This is + * a very useful and long desired include file which contains several + * very precise definitions for integer scalar types that is + * critically important for making portable several classes of + * applications including cryptography, hashing, variable length + * integer libraries and so on. But for most developers its likely + * useful just for programming sanity. + * + * The problem is that most compiler vendors have decided not to + * implement the C99 standard, and the next C++ language standard + * (which has a lot more mindshare these days) will be a long time in + * coming and its unknown whether or not it will include stdint.h or + * how much adoption it will have. Either way, it will be a long time + * before all compilers come with a stdint.h and it also does nothing + * for the extremely large number of compilers available today which + * do not include this file, or anything comparable to it. + * + * So that's what this file is all about. Its an attempt to build a + * single universal include file that works on as many platforms as + * possible to deliver what stdint.h is supposed to. A few things + * that should be noted about this file: + * + * 1) It is not guaranteed to be portable and/or present an identical + * interface on all platforms. The extreme variability of the + * ANSI C standard makes this an impossibility right from the + * very get go. Its really only meant to be useful for the vast + * majority of platforms that possess the capability of + * implementing usefully and precisely defined, standard sized + * integer scalars. Systems which are not intrinsically 2s + * complement may produce invalid constants. + * + * 2) There is an unavoidable use of non-reserved symbols. + * + * 3) Other standard include files are invoked. + * + * 4) This file may come in conflict with future platforms that do + * include stdint.h. The hope is that one or the other can be + * used with no real difference. + * + * 5) In the current verison, if your platform can't represent + * int32_t, int16_t and int8_t, it just dumps out with a compiler + * error. + * + * 6) 64 bit integers may or may not be defined. Test for their + * presence with the test: #ifdef INT64_MAX or #ifdef UINT64_MAX. + * Note that this is different from the C99 specification which + * requires the existence of 64 bit support in the compiler.

At the heart of the bstring library +(Bstrlib for short) is the management of "bstring"s which are a significant +improvement over '\0' terminated char buffers. + +=============================================================================== + +Motivation +---------- + +The standard C string library has serious problems: + + 1) Its use of '\0' to denote the end of the string means knowing a + string's length is O(n) when it could be O(1). + 2) It imposes an interpretation for the character value '\0'. + 3) gets() always exposes the application to a buffer overflow. + 4) strtok() modifies the string its parsing and thus may not be usable in + programs which are re-entrant or multithreaded. + 5) fgets has the unusual semantic of ignoring '\0's that occur before + '\n's are consumed. + 6) There is no memory management, and actions performed such as strcpy, + strcat and sprintf are common places for buffer overflows. + 7) strncpy() doesn't '\0' terminate the destination in some cases. + 8) Passing NULL to C library string functions causes an undefined NULL + pointer access. + 9) Parameter aliasing (overlapping, or self-referencing parameters) + within most C library functions has undefined behavior. + 10) Many C library string function calls take integer parameters with + restricted legal ranges. Parameters passed outside these ranges are + not typically detected and cause undefined behavior. + +So the desire is to create an alternative string library that does not suffer +from the above problems and adds in the following functionality: + + 1) Incorporate string functionality seen from other languages. + a) MID$() - from BASIC + b) split()/join() - from Python + c) string/char x n - from Perl + 2) Implement analogs to functions that combine stream IO and char buffers + without creating a dependency on stream IO functionality. + 3) Implement the basic text editor-style functions insert, delete, find, + and replace. + 4) Implement reference based sub-string access (as a generalization of + pointer arithmetic.) + 5) Implement runtime write protection for strings. + +There is also a desire to avoid "API-bloat". So functionality that can be +implemented trivially in other functionality is omitted. So there is no +left$() or right$() or reverse() or anything like that as part of the core +functionality. + +Explaining Bstrings +------------------- + +A bstring is basically a header which wraps a pointer to a char buffer. Lets +start with the declaration of a struct tagbstring: + + struct tagbstring { + int mlen; + int slen; + unsigned char * data; + }; + +This definition is considered exposed, not opaque (though it is neither +necessary nor recommended that low level maintenance of bstrings be performed +whenever the abstract interfaces are sufficient). The mlen field (usually) +describes a lower bound for the memory allocated for the data field. The +slen field describes the exact length for the bstring. The data field is a +single contiguous buffer of unsigned chars. Note that the existence of a '\0' +character in the unsigned char buffer pointed to by the data field does not +necessarily denote the end of the bstring. + +To be a well formed modifiable bstring the mlen field must be at least the +length of the slen field, and slen must be non-negative. Furthermore, the +data field must point to a valid buffer in which access to the first mlen +characters has been acquired. So the minimal check for correctness is: + + (slen >= 0 && mlen >= slen && data != NULL) + +bstrings returned by bstring functions can be assumed to be either NULL or +satisfy the above property. (When bstrings are only readable, the mlen >= +slen restriction is not required; this is discussed later in this section.) +A bstring itself is just a pointer to a struct tagbstring: + + typedef struct tagbstring * bstring; + +Note that use of the prefix "tag" in struct tagbstring is required to work +around the inconsistency between C and C++'s struct namespace usage. This +definition is also considered exposed. + +Bstrlib basically manages bstrings allocated as a header and an associated +data-buffer. Since the implementation is exposed, they can also be +constructed manually. Functions which mutate bstrings assume that the header +and data buffer have been malloced; the bstring library may perform free() or +realloc() on both the header and data buffer of any bstring parameter. +Functions which return bstring's create new bstrings. The string memory is +freed by a bdestroy() call (or using the bstrFree macro). + +The following related typedef is also provided: + + typedef const struct tagbstring * const_bstring; + +which is also considered exposed. These are directly bstring compatible (no +casting required) but are just used for parameters which are meant to be +non-mutable. So in general, bstring parameters which are read as input but +not meant to be modified will be declared as const_bstring, and bstring +parameters which may be modified will be declared as bstring. This convention +is recommended for user written functions as well. + +Since bstrings maintain interoperability with C library char-buffer style +strings, all functions which modify, update or create bstrings also append a +'\0' character into the position slen + 1. This trailing '\0' character is +not required for bstrings input to the bstring functions; this is provided +solely as a convenience for interoperability with standard C char-buffer +functionality. + +Analogs for the ANSI C string library functions have been created when they +are necessary, but have also been left out when they are not. In particular +there are no functions analogous to fwrite, or puts just for the purposes of +bstring. The ->data member of any string is exposed, and therefore can be +used just as easily as char buffers for C functions which read strings. + +For those that wish to hand construct bstrings, the following should be kept +in mind: + + 1) While bstrlib can accept constructed bstrings without terminating + '\0' characters, the rest of the C language string library will not + function properly on such non-terminated strings. This is obvious + but must be kept in mind. + 2) If it is intended that a constructed bstring be written to by the + bstring library functions then the data portion should be allocated + by the malloc function and the slen and mlen fields should be entered + properly. The struct tagbstring header is not reallocated, and only + freed by bdestroy. + 3) Writing arbitrary '\0' characters at various places in the string + will not modify its length as perceived by the bstring library + functions. In fact, '\0' is a legitimate non-terminating character + for a bstring to contain. + 4) For read only parameters, bstring functions do not check the mlen. + I.e., the minimal correctness requirements are reduced to: + + (slen >= 0 && data != NULL) + +Better pointer arithmetic +------------------------- + +One built-in feature of '\0' terminated char * strings, is that its very easy +and fast to obtain a reference to the tail of any string using pointer +arithmetic. Bstrlib does one better by providing a way to get a reference to +any substring of a bstring (or any other length delimited block of memory.) +So rather than just having pointer arithmetic, with bstrlib one essentially +has segment arithmetic. This is achieved using the macro blk2tbstr() which +builds a reference to a block of memory and the macro bmid2tbstr() which +builds a reference to a segment of a bstring. Bstrlib also includes +functions for direct consumption of memory blocks into bstrings, namely +bcatblk () and blk2bstr (). + +One scenario where this can be extremely useful is when string contains many +substrings which one would like to pass as read-only reference parameters to +some string consuming function without the need to allocate entire new +containers for the string data. More concretely, imagine parsing a command +line string whose parameters are space delimited. This can only be done for +tails of the string with '\0' terminated char * strings. + +Improved NULL semantics and error handling +------------------------------------------ + +Unless otherwise noted, if a NULL pointer is passed as a bstring or any other +detectably illegal parameter, the called function will return with an error +indicator (either NULL or BSTR_ERR) rather than simply performing a NULL +pointer access, or having undefined behavior. + +To illustrate the value of this, consider the following example: + + strcpy (p = malloc (13 * sizeof (char)), "Hello,"); + strcat (p, " World"); + +This is not correct because malloc may return NULL (due to an out of memory +condition), and the behaviour of strcpy is undefined if either of its +parameters are NULL. However: + + bstrcat (p = bfromcstr ("Hello,"), q = bfromcstr (" World")); + bdestroy (q); + +is well defined, because if either p or q are assigned NULL (indicating a +failure to allocate memory) both bstrcat and bdestroy will recognize it and +perform no detrimental action. + +Note that it is not necessary to check any of the members of a returned +bstring for internal correctness (in particular the data member does not need +to be checked against NULL when the header is non-NULL), since this is +assured by the bstring library itself. + +bStreams +-------- + +In addition to the bgets and bread functions, bstrlib can abstract streams +with a high performance read only stream called a bStream. In general, the +idea is to open a core stream (with something like fopen) then pass its +handle as well as a bNread function pointer (like fread) to the bsopen +function which will return a handle to an open bStream. Then the functions +bsread, bsreadln or bsreadlns can be called to read portions of the stream. +Finally, the bsclose function is called to close the bStream -- it will +return a handle to the original (core) stream. So bStreams, essentially, +wrap other streams. + +The bStreams have two main advantages over the bgets and bread (as well as +fgets/ungetc) paradigms: + +1) Improved functionality via the bunread function which allows a stream to + unread characters, giving the bStream stack-like functionality if so + desired. +2) A very high performance bsreadln function. The C library function fgets() + (and the bgets function) can typically be written as a loop on top of + fgetc(), thus paying all of the overhead costs of calling fgetc on a per + character basis. bsreadln will read blocks at a time, thus amortizing the + overhead of fread calls over many characters at once. + +However, clearly bStreams are suboptimal or unusable for certain kinds of +streams (stdin) or certain usage patterns (a few spotty, or non-sequential +reads from a slow stream.) For those situations, using bgets will be more +appropriate. + +The semantics of bStreams allows practical construction of layerable data +streams. What this means is that by writing a bNread compatible function on +top of a bStream, one can construct a new bStream on top of it. This can be +useful for writing multi-pass parsers that don't actually read the entire +input more than once and don't require the use of intermediate storage. + +Aliasing +-------- + +Aliasing occurs when a function is given two parameters which point to data +structures which overlap in the memory they occupy. While this does not +disturb read only functions, for many libraries this can make functions that +write to these memory locations malfunction. This is a common problem of the +C standard library and especially the string functions in the C standard +library. + +The C standard string library is entirely char by char oriented (as is +bstring) which makes conforming implementations alias safe for some +scenarios. However no actual detection of aliasing is typically performed, +so it is easy to find cases where the aliasing will cause anomolous or +undesirable behaviour (consider: strcat (p, p).) The C99 standard includes +the "restrict" pointer modifier which allows the compiler to document and +assume a no-alias condition on usage. However, only the most trivial cases +can be caught (if at all) by the compiler at compile time, and thus there is +no actual enforcement of non-aliasing. + +Bstrlib, by contrast, permits aliasing and is completely aliasing safe, in +the C99 sense of aliasing. That is to say, under the assumption that +pointers of incompatible types from distinct objects can never alias, bstrlib +is completely aliasing safe. (In practice this means that the data buffer +portion of any bstring and header of any bstring are assumed to never alias.) +With the exception of the reference building macros, the library behaves as +if all read-only parameters are first copied and replaced by temporary +non-aliased parameters before any writing to any output bstring is performed +(though actual copying is extremely rarely ever done.) + +Besides being a useful safety feature, bstring searching/comparison +functions can improve to O(1) execution when aliasing is detected. + +Note that aliasing detection and handling code in Bstrlib is generally +extremely cheap. There is almost never any appreciable performance penalty +for using aliased parameters. + +Reenterancy +----------- + +Nearly every function in Bstrlib is a leaf function, and is completely +reenterable with the exception of writing to common bstrings. The split +functions which use a callback mechanism requires only that the source string +not be destroyed by the callback function unless the callback function returns +with an error status (note that Bstrlib functions which return an error do +not modify the string in any way.) The string can in fact be modified by the +callback and the behaviour is deterministic. See the documentation of the +various split functions for more details. + +Undefined scenarios +------------------- + +One of the basic important premises for Bstrlib is to not to increase the +propogation of undefined situations from parameters that are otherwise legal +in of themselves. In particular, except for extremely marginal cases, usages +of bstrings that use the bstring library functions alone cannot lead to any +undefined action. But due to C/C++ language and library limitations, there +is no way to define a non-trivial library that is completely without +undefined operations. All such possible undefined operations are described +below: + +1) bstrings or struct tagbstrings that are not explicitely initialized cannot + be passed as a parameter to any bstring function. +2) The members of the NULL bstring cannot be accessed directly. (Though all + APIs and macros detect the NULL bstring.) +3) A bstring whose data member has not been obtained from a malloc or + compatible call and which is write accessible passed as a writable + parameter will lead to undefined results. (i.e., do not writeAllow any + constructed bstrings unless the data portion has been obtained from the + heap.) +4) If the headers of two strings alias but are not identical (which can only + happen via a defective manual construction), then passing them to a + bstring function in which one is writable is not defined. +5) If the mlen member is larger than the actual accessible length of the data + member for a writable bstring, or if the slen member is larger than the + readable length of the data member for a readable bstring, then the + corresponding bstring operations are undefined. +6) Any bstring definition whose header or accessible data portion has been + assigned to inaccessible or otherwise illegal memory clearly cannot be + acted upon by the bstring library in any way. +7) Destroying the source of an incremental split from within the callback + and not returning with a negative value (indicating that it should abort) + will lead to undefined behaviour. (Though *modifying* or adjusting the + state of the source data, even if those modification fail within the + bstrlib API, has well defined behavior.) +8) Modifying a bstring which is write protected by direct access has + undefined behavior. + +While this may seem like a long list, with the exception of invalid uses of +the writeAllow macro, and source destruction during an iterative split +without an accompanying abort, no usage of the bstring API alone can cause +any undefined scenario to occurr. I.e., the policy of restricting usage of +bstrings to the bstring API can significantly reduce the risk of runtime +errors (in practice it should eliminate them) related to string manipulation +due to undefined action. + +C++ wrapper +----------- + +A C++ wrapper has been created to enable bstring functionality for C++ in the +most natural (for C++ programers) way possible. The mandate for the C++ +wrapper is different from the base C bstring library. Since the C++ language +has far more abstracting capabilities, the CBString structure is considered +fully abstracted -- i.e., hand generated CBStrings are not supported (though +conversion from a struct tagbstring is allowed) and all detectable errors are +manifest as thrown exceptions. + +- The C++ class definitions are all under the namespace Bstrlib. bstrwrap.h + enables this namespace (with a using namespace Bstrlib; directive at the + end) unless the macro BSTRLIB_DONT_ASSUME_NAMESPACE has been defined before + it is included. + +- Erroneous accesses results in an exception being thrown. The exception + parameter is of type "struct CBStringException" which is derived from + std::exception if STL is used. A verbose description of the error message + can be obtained from the what() method. + +- CBString is a C++ structure derived from a struct tagbstring. An address + of a CBString cast to a bstring must not be passed to bdestroy. The bstring + C API has been made C++ safe and can be used directly in a C++ project. + +- It includes constructors which can take a char, '\0' terminated char + buffer, tagbstring, (char, repeat-value), a length delimited buffer or a + CBStringList to initialize it. + +- Concatenation is performed with the + and += operators. Comparisons are + done with the ==, !=, <, >, <= and >= operators. Note that == and != use + the biseq call, while <, >, <= and >= use bstrcmp. + +- CBString's can be directly cast to const character buffers. + +- CBString's can be directly cast to double, float, int or unsigned int so + long as the CBString are decimal representations of those types (otherwise + an exception will be thrown). Converting the other way should be done with + the format(a) method(s). + +- CBString contains the length, character and [] accessor methods. The + character and [] accessors are aliases of each other. If the bounds for + the string are exceeded, an exception is thrown. To avoid the overhead for + this check, first cast the CBString to a (const char *) and use [] to + dereference the array as normal. Note that the character and [] accessor + methods allows both reading and writing of individual characters. + +- The methods: format, formata, find, reversefind, findcaseless, + reversefindcaseless, midstr, insert, insertchrs, replace, findreplace, + findreplacecaseless, remove, findchr, nfindchr, alloc, toupper, tolower, + gets, read are analogous to the functions that can be found in the C API. + +- The caselessEqual and caselessCmp methods are analogous to biseqcaseless + and bstricmp functions respectively. + +- Note that just like the bformat function, the format and formata methods do + not automatically cast CBStrings into char * strings for "%s"-type + substitutions: + + CBString w("world"); + CBString h("Hello"); + CBString hw; + + /* The casts are necessary */ + hw.format ("%s, %s", (const char *)h, (const char *)w); + +- The methods trunc and repeat have been added instead of using pattern. + +- ltrim, rtrim and trim methods have been added. These remove characters + from a given character string set (defaulting to the whitespace characters) + from either the left, right or both ends of the CBString, respectively. + +- The method setsubstr is also analogous in functionality to bsetstr, except + that it cannot be passed NULL. Instead the method fill and the fill-style + constructor have been supplied to enable this functionality. + +- The writeprotect(), writeallow() and iswriteprotected() methods are + analogous to the bwriteprotect(), bwriteallow() and biswriteprotected() + macros in the C API. Write protection semantics in CBString are stronger + than with the C API in that indexed character assignment is checked for + write protection. However, unlike with the C API, a write protected + CBString can be destroyed by the destructor. + +- CBStream is a C++ structure which wraps a struct bStream (its not derived + from it, since destruction is slightly different). It is constructed by + passing in a bNread function pointer and a stream parameter cast to void *. + This structure includes methods for detecting eof, setting the buffer + length, reading the whole stream or reading entries line by line or block + by block, an unread function, and a peek function. + +- If STL is available, the CBStringList structure is derived from a vector of + CBString with various split methods. The split method has been overloaded + to accept either a character or CBString as the second parameter (when the + split parameter is a CBString any character in that CBString is used as a + seperator). The splitstr method takes a CBString as a substring seperator. + Joins can be performed via a CBString constructor which takes a + CBStringList as a parameter, or just using the CBString::join() method. + +- If there is proper support for std::iostreams, then the >> and << operators + and the getline() function have been added (with semantics the same as + those for std::string). + +Multithreading +-------------- + +A mutable bstring is kind of analogous to a small (two entry) linked list +allocated by malloc, with all aliasing completely under programmer control. +I.e., manipulation of one bstring will never affect any other distinct +bstring unless explicitely constructed to do so by the programmer via hand +construction or via building a reference. Bstrlib also does not use any +static or global storage, so there are no hidden unremovable race conditions. +Bstrings are also clearly not inherently thread local. So just like +char *'s, bstrings can be passed around from thread to thread and shared and +so on, so long as modifications to a bstring correspond to some kind of +exclusive access lock as should be expected (or if the bstring is read-only, +which can be enforced by bstring write protection) for any sort of shared +object in a multithreaded environment. + +Bsafe module +------------ + +For convenience, a bsafe module has been included. The idea is that if this +module is included, inadvertant usage of the most dangerous C functions will +be overridden and lead to an immediate run time abort. Of course, it should +be emphasized that usage of this module is completely optional. The +intention is essentially to provide an option for creating project safety +rules which can be enforced mechanically rather than socially. This is +useful for larger, or open development projects where its more difficult to +enforce social rules or "coding conventions". + +Problems not solved +------------------- + +Bstrlib is written for the C and C++ languages, which have inherent weaknesses +that cannot be easily solved: + +1. Memory leaks: Forgetting to call bdestroy on a bstring that is about to be + unreferenced, just as forgetting to call free on a heap buffer that is + about to be dereferenced. Though bstrlib itself is leak free. +2. Read before write usage: In C, declaring an auto bstring does not + automatically fill it with legal/valid contents. This problem has been + somewhat mitigated in C++. (The bstrDeclare and bstrFree macros from + bstraux can be used to help mitigate this problem.) + +Other problems not addressed: + +3. Built-in mutex usage to automatically avoid all bstring internal race + conditions in multitasking environments: The problem with trying to + implement such things at this low a level is that it is typically more + efficient to use locks in higher level primitives. There is also no + platform independent way to implement locks or mutexes. +4. Unicode/widecharacter support. + +Note that except for spotty support of wide characters, the default C +standard library does not address any of these problems either. + +Configurable compilation options +-------------------------------- + +All configuration options are meant solely for the purpose of compiler +compatibility. Configuration options are not meant to change the semantics +or capabilities of the library, except where it is unavoidable. + +Since some C++ compilers don't include the Standard Template Library and some +have the options of disabling exception handling, a number of macros can be +used to conditionally compile support for each of this: + +BSTRLIB_CAN_USE_STL + + - defining this will enable the used of the Standard Template Library. + Defining BSTRLIB_CAN_USE_STL overrides the BSTRLIB_CANNOT_USE_STL macro. + +BSTRLIB_CANNOT_USE_STL + + - defining this will disable the use of the Standard Template Library. + Defining BSTRLIB_CAN_USE_STL overrides the BSTRLIB_CANNOT_USE_STL macro. + +BSTRLIB_CAN_USE_IOSTREAM + + - defining this will enable the used of streams from class std. Defining + BSTRLIB_CAN_USE_IOSTREAM overrides the BSTRLIB_CANNOT_USE_IOSTREAM macro. + +BSTRLIB_CANNOT_USE_IOSTREAM + + - defining this will disable the use of streams from class std. Defining + BSTRLIB_CAN_USE_IOSTREAM overrides the BSTRLIB_CANNOT_USE_IOSTREAM macro. + +BSTRLIB_THROWS_EXCEPTIONS + + - defining this will enable the exception handling within bstring. + Defining BSTRLIB_THROWS_EXCEPTIONS overrides the + BSTRLIB_DOESNT_THROWS_EXCEPTIONS macro. + +BSTRLIB_DOESNT_THROW_EXCEPTIONS + + - defining this will disable the exception handling within bstring. + Defining BSTRLIB_THROWS_EXCEPTIONS overrides the + BSTRLIB_DOESNT_THROW_EXCEPTIONS macro. + +Note that these macros must be defined consistently throughout all modules +that use CBStrings including bstrwrap.cpp. + +Some older C compilers do not support functions such as vsnprintf.

The Bstrlib alternatives do +not suffer from those sorts of problems. + +The substitute for strncat can be performed with higher performance by using +the blk2tbstr macro to create a presized second operand for bconcat. + +C-library Bstring alternative CBString alternative +--------- ------------------- -------------------- +strspn strspn acceptable strspn acceptable +strcspn strcspn acceptable strcspn acceptable +strnset strnset acceptable strnset acceptable +printf printf acceptable printf acceptable +puts puts acceptable puts acceptable +fprintf fprintf acceptable fprintf acceptable +fputs fputs acceptable fputs acceptable +memcmp memcmp acceptable memcmp acceptable + +Remember that Bstring (and CBstring) functions will automatically append the +'\0' character to the character data buffer. So by simply accessing the data +buffer directly, ordinary C string library functions can be called directly +on them. Note that bstrcmp is not the same as memcmp in exactly the same way +that strcmp is not the same as memcmp. + +C-library Bstring alternative CBString alternative +--------- ------------------- -------------------- +fread balloc + fread ::alloc + fread +fgets balloc + fgets ::alloc + fgets + +These are odd ones because of the exact sizing of the buffer required. The +Bstring and CBString alternatives requires that the buffers are forced to +hold at least the prescribed length, then just use fread or fgets directly. +However, typically the automatic memory management of Bstring and CBstring +will make the typical use of fgets and fread to read specifically sized +strings unnecessary. + +Implementation Choices +---------------------- + +Overhead: +......... + +The bstring library has more overhead versus straight char buffers for most +functions. This overhead is essentially just the memory management and +string header allocation. This overhead usually only shows up for small +string manipulations. The performance loss has to be considered in +light of the following: + +1) What would be the performance loss of trying to write this management + code in one's own application? +2) Since the bstring library source code is given, a sufficiently powerful + modern inlining globally optimizing compiler can remove function call + overhead. + +Since the data type is exposed, a developer can replace any unsatisfactory +function with their own inline implementation. And that is besides the main +point of what the better string library is mainly meant to provide. Any +overhead lost has to be compared against the value of the safe abstraction +for coupling memory management and string functionality. + +Performance of the C interface: +............................... + +The algorithms used have performance advantages versus the analogous C +library functions. For example: + +1. bfromcstr/blk2str/bstrcpy versus strcpy/strdup. By using memmove instead + of strcpy, the break condition of the copy loop is based on an independent + counter (that should be allocated in a register) rather than having to + check the results of the load. Modern out-of-order executing CPUs can + parallelize the final branch mis-predict penality with the loading of the + source string. Some CPUs will also tend to have better built-in hardware + support for counted memory moves than load-compare-store. (This is a + minor, but non-zero gain.) +2. biseq versus strcmp. If the strings are unequal in length, bsiseq will + return in O(1) time. If the strings are aliased, or have aliased data + buffers, biseq will return in O(1) time. strcmp will always be O(k), + where k is the length of the common prefix or the whole string if they are + identical. +3. ->slen versus strlen. ->slen is obviously always O(1), while strlen is + always O(n) where n is the length of the string. +4. bconcat versus strcat. Both rely on precomputing the length of the + destination string argument, which will favor the bstring library. On + iterated concatenations the performance difference can be enormous. +5. bsreadln versus fgets. The bsreadln function reads large blocks at a time + from the given stream, then parses out lines from the buffers directly. + Some C libraries will implement fgets as a loop over single fgetc calls. + Testing indicates that the bsreadln approach can be several times faster + for fast stream devices (such as a file that has been entirely cached.) +6. bsplits/bsplitscb versus strspn. Accelerators for the set of match + characters are generated only once. +7. binstr versus strstr. The binstr implementation unrolls the loops to + help reduce loop overhead. This will matter if the target string is + long and source string is not found very early in the target string. + With strstr, while it is possible to unroll the source contents, it is + not possible to do so with the destination contents in a way that is + effective because every destination character must be tested against + '\0' before proceeding to the next character. +8. bReverse versus strrev. The C function must find the end of the string + first before swaping character pairs. +9. bstrrchr versus no comparable C function. Its not hard to write some C + code to search for a character from the end going backwards. But there + is no way to do this without computing the length of the string with + strlen. + +Practical testing indicates that in general Bstrlib is never signifcantly +slower than the C library for common operations, while very often having a +performance advantage that ranges from significant to massive. Even for +functions like b(n)inchr versus str(c)spn() (where, in theory, there is no +advantage for the Bstrlib architecture) the performance of Bstrlib is vastly +superior to most tested C library implementations. + +Some of Bstrlib's extra functionality also lead to inevitable performance +advantages over typical C solutions. For example, using the blk2tbstr macro, +one can (in O(1) time) generate an internal substring by reference while not +disturbing the original string. If disturbing the original string is not an +option, typically, a comparable char * solution would have to make a copy of +the substring to provide similar functionality. Another example is reverse +character set scanning -- the str(c)spn functions only scan in a forward +direction which can complicate some parsing algorithms. + +Where high performance char * based algorithms are available, Bstrlib can +still leverage them by accessing the ->data field on bstrings. So +realistically Bstrlib can never be significantly slower than any standard +'\0' terminated char * based solutions. + +Performance of the C++ interface: +................................. + +The C++ interface has been designed with an emphasis on abstraction and safety +first. However, since it is substantially a wrapper for the C bstring +functions, for longer strings the performance comments described in the +"Performance of the C interface" section above still apply. Note that the +(CBString *) type can be directly cast to a (bstring) type, and passed as +parameters to the C functions (though a CBString must never be passed to +bdestroy.) + +Probably the most controversial choice is performing full bounds checking on +the [] operator. This decision was made because 1) the fast alternative of +not bounds checking is still available by first casting the CBString to a +(const char *) buffer or to a (struct tagbstring) then derefencing .data and +2) because the lack of bounds checking is seen as one of the main weaknesses +of C/C++ versus other languages. This check being done on every access leads +to individual character extraction being actually slower than other languages +in this one respect (other language's compilers will normally dedicate more +resources on hoisting or removing bounds checking as necessary) but otherwise +bring C++ up to the level of other languages in terms of functionality. + +It is common for other C++ libraries to leverage the abstractions provided by +C++ to use reference counting and "copy on write" policies. While these +techniques can speed up some scenarios, they impose a problem with respect to +thread safety. bstrings and CBStrings can be properly protected with +"per-object" mutexes, meaning that two bstrlib calls can be made and execute +simultaneously, so long as the bstrings and CBstrings are distinct. With a +reference count and alias before copy on write policy, global mutexes are +required that prevent multiple calls to the strings library to execute +simultaneously regardless of whether or not the strings represent the same +string. + +One interesting trade off in CBString is that the default constructor is not +trivial. I.e., it always prepares a ready to use memory buffer. The purpose +is to ensure that there is a uniform internal composition for any functioning +CBString that is compatible with bstrings. It also means that the other +methods in the class are not forced to perform "late initialization" checks. +In the end it means that construction of CBStrings are slower than other +comparable C++ string classes. Initial testing, however, indicates that +CBString outperforms std::string and MFC's CString, for example, in all other +operations. So to work around this weakness it is recommended that CBString +declarations be pushed outside of inner loops. + +Practical testing indicates that with the exception of the caveats given +above (constructors and safe index character manipulations) the C++ API for +Bstrlib generally outperforms popular standard C++ string classes. Amongst +the standard libraries and compilers, the quality of concatenation operations +varies wildly and very little care has gone into search functions. Bstrlib +dominates those performance benchmarks. + +Memory management: +.................. + +The bstring functions which write and modify bstrings will automatically +reallocate the backing memory for the char buffer whenever it is required to +grow. The algorithm for resizing chosen is to snap up to sizes that are a +power of two which are sufficient to hold the intended new size. Memory +reallocation is not performed when the required size of the buffer is +decreased. This behavior can be relied on, and is necessary to make the +behaviour of balloc deterministic. This trades off additional memory usage +for decreasing the frequency for required reallocations: + +1. For any bstring whose size never exceeds n, its buffer is not ever + reallocated more than log_2(n) times for its lifetime. +2. For any bstring whose size never exceeds n, its buffer is never more than + 2*(n+1) in length. (The extra characters beyond 2*n are to allow for the + implicit '\0' which is always added by the bstring modifying functions.) + +Decreasing the buffer size when the string decreases in size would violate 1) +above and in real world case lead to pathological heap thrashing. Similarly, +allocating more tightly than "least power of 2 greater than necessary" would +lead to a violation of 1) and have the same potential for heap thrashing. + +Property 2) needs emphasizing. Although the memory allocated is always a +power of 2, for a bstring that grows linearly in size, its buffer memory also +grows linearly, not exponentially. The reason is that the amount of extra +space increases with each reallocation, which decreases the frequency of +future reallocations. + +Obviously, given that bstring writing functions may reallocate the data +buffer backing the target bstring, one should not attempt to cache the data +buffer address and use it after such bstring functions have been called. +This includes making reference struct tagbstrings which alias to a writable +bstring. + +balloc or bfromcstralloc can be used to preallocate the minimum amount of +space used for a given bstring. This will reduce even further the number of +times the data portion is reallocated. If the length of the string is never +more than one less than the memory length then there will be no further +reallocations. + +Note that invoking the bwriteallow macro may increase the number of reallocs +by one more than necessary for every call to bwriteallow interleaved with any +bstring API which writes to this bstring. + +The library does not use any mechanism for automatic clean up for the C API. +Thus explicit clean up via calls to bdestroy() are required to avoid memory +leaks. + +Constant and static tagbstrings: +................................ + +A struct tagbstring can be write protected from any bstrlib function using +the bwriteprotect macro. A write protected struct tagbstring can then be +reset to being writable via the bwriteallow macro. There is, of course, no +protection from attempts to directly access the bstring members. Modifying a +bstring which is write protected by direct access has undefined behavior. + +static struct tagbstrings can be declared via the bsStatic macro. They are +considered permanently unwritable. Such struct tagbstrings's are declared +such that attempts to write to it are not well defined. Invoking either +bwriteallow or bwriteprotect on static struct tagbstrings has no effect. + +struct tagbstring's initialized via btfromcstr or blk2tbstr are protected by +default but can be made writeable via the bwriteallow macro. If bwriteallow +is called on such struct tagbstring's, it is the programmer's responsibility +to ensure that: + +1) the buffer supplied was allocated from the heap. +2) bdestroy is not called on this tagbstring (unless the header itself has + also been allocated from the heap.) +3) free is called on the buffer to reclaim its memory. + +bwriteallow and bwriteprotect can be invoked on ordinary bstrings (they have +to be dereferenced with the (*) operator to get the levels of indirection +correct) to give them write protection. + +Buffer declaration: +................... + +The memory buffer is actually declared "unsigned char *" instead of "char *". +The reason for this is to trigger compiler warnings whenever uncasted char +buffers are assigned to the data portion of a bstring. This will draw more +diligent programmers into taking a second look at the code where they +have carelessly left off the typically required cast. (Research from +AT&T/Lucent indicates that additional programmer eyeballs is one of the most +effective mechanisms at ferreting out bugs.) + +Function pointers: +.................. + +The bgets, bread and bStream functions use function pointers to obtain +strings from data streams. The function pointer declarations have been +specifically chosen to be compatible with the fgetc and fread functions. +While this may seem to be a convoluted way of implementing fgets and fread +style functionality, it has been specifically designed this way to ensure +that there is no dependency on a single narrowly defined set of device +interfaces, such as just stream I/O. In the embedded world, its quite +possible to have environments where such interfaces may not exist in the +standard C library form. Furthermore, the generalization that this opens up +allows for more sophisticated uses for these functions (performing an fgets +like function on a socket, for example.) By using function pointers, it also +allows such abstract stream interfaces to be created using the bstring library +itself while not creating a circular dependency. + +Use of int's for sizes: +....................... + +This is just a recognition that 16bit platforms with requirements for strings +that are larger than 64K and 32bit+ platforms with requirements for strings +that are larger than 4GB are pretty marginal. The main focus is for 32bit +platforms, and emerging 64bit platforms with reasonable < 4GB string +requirements. Using ints allows for negative values which has meaning +internally to bstrlib. + +Semantic consideration: +....................... + +Certain care needs to be taken when copying and aliasing bstrings. A bstring +is essentially a pointer type which points to a multipart abstract data +structure. Thus usage, and lifetime of bstrings have semantics that follow +these considerations. For example: + + bstring a, b; + struct tagbstring t; + + a = bfromcstr("Hello"); /* Create new bstring and copy "Hello" into it. */ + b = a; /* Alias b to the contents of a. */ + t = *a; /* Create a current instance pseudo-alias of a. */ + bconcat (a, b); /* Double a and b, t is now undefined. */ + bdestroy (a); /* Destroy the contents of both a and b. */ + +Variables of type bstring are really just references that point to real +bstring objects. The equal operator (=) creates aliases, and the asterisk +dereference operator (*) creates a kind of alias to the current instance (which +is generally not useful for any purpose.) Using bstrcpy() is the correct way +of creating duplicate instances. The ampersand operator (&) is useful for +creating aliases to struct tagbstrings (remembering that constructed struct +tagbstrings are not writable by default.) + +CBStrings use complete copy semantics for the equal operator (=), and thus do +not have these sorts of issues. + +Debugging: +.......... + +Bstrings have a simple, exposed definition and construction, and the library +itself is open source. So most debugging is going to be fairly straight- +forward. But the memory for bstrings come from the heap, which can often be +corrupted indirectly, and it might not be obvious what has happened even from +direct examination of the contents in a debugger or a core dump. There are +some tools such as Purify, Insure++ and Electric Fence which can help solve +such problems, however another common approach is to directly instrument the +calls to malloc, realloc, calloc, free, memcpy, memmove and/or other calls +by overriding them with macro definitions. + +Although the user could hack on the Bstrlib sources directly as necessary to +perform such an instrumentation, Bstrlib comes with a built-in mechanism for +doing this. By defining the macro BSTRLIB_MEMORY_DEBUG and providing an +include file named memdbg.h this will force the core Bstrlib modules to +attempt to include this file. In such a file, macros could be defined which +overrides Bstrlib's useage of the C standard library. + +Rather than calling malloc, realloc, free, memcpy or memmove directly, Bstrlib +emits the macros bstr__alloc, bstr__realloc, bstr__free, bstr__memcpy and +bstr__memmove in their place respectively. By default these macros are simply +assigned to be equivalent to their corresponding C standard library function +call. However, if they are given earlier macro definitions (via the back +door include file) they will not be given their default definition. In this +way Bstrlib's interface to the standard library can be changed but without +having to directly redefine or link standard library symbols (both of which +are not strictly ANSI C compliant.) + +An example definition might include: + + #define bstr__alloc(sz) X_malloc ((sz), __LINE__, __FILE__) + +which might help contextualize heap entries in a debugging environment. + +The NULL parameter and sanity checking of bstrings is part of the Bstrlib +API, and thus Bstrlib itself does not present any different modes which would +correspond to "Debug" or "Release" modes. Bstrlib always contains mechanisms +which one might think of as debugging features, but retains the performance +and small memory footprint one would normally associate with release mode +code. + +Integration Microsoft's Visual Studio debugger: +............................................... + +Microsoft's Visual Studio debugger has a capability of customizable mouse +float over data type descriptions. This is accomplished by editting the +AUTOEXP.DAT file to include the following: + + ; new for CBString + tagbstring =slen=<slen> mlen=<mlen> <data,st> + Bstrlib::CBStringList =count=<size()> + +In Visual C++ 6.0 this file is located in the directory: + + C:\Program Files\Microsoft Visual Studio\Common\MSDev98\Bin + +and in Visual Studio .NET 2003 its located here: + + C:\Program Files\Microsoft Visual Studio .NET 2003\Common7\Packages\Debugger + +This will improve the ability of debugging with Bstrlib under Visual Studio. + +Security +-------- + +Bstrlib does not come with explicit security features outside of its fairly +comprehensive error detection, coupled with its strict semantic support. +That is to say that certain common security problems, such as buffer overrun, +constant overwrite, arbitrary truncation etc, are far less likely to happen +inadvertently. Where it does help, Bstrlib maximizes its advantage by +providing developers a simple adoption path that lets them leave less secure +string mechanisms behind. The library will not leave developers wanting, so +they will be less likely to add new code using a less secure string library +to add functionality that might be missing from Bstrlib. + +That said there are a number of security ideas not addressed by Bstrlib: + +1. Race condition exploitation (i.e., verifying a string's contents, then +raising the privilege level and execute it as a shell command as two +non-atomic steps) is well beyond the scope of what Bstrlib can provide. It +should be noted that MFC's built-in string mutex actually does not solve this +problem either -- it just removes immediate data corruption as a possible +outcome of such exploit attempts (it can be argued that this is worse, since +it will leave no trace of the exploitation). In general race conditions have +to be dealt with by careful design and implementation; it cannot be assisted +by a string library. + +2. Any kind of access control or security attributes to prevent usage in +dangerous interfaces such as system(). Perl includes a "trust" attribute +which can be endowed upon strings that are intended to be passed to such +dangerous interfaces. However, Perl's solution reflects its own limitations +-- notably that it is not a strongly typed language. In the example code for +Bstrlib, there is a module called taint.cpp. It demonstrates how to write a +simple wrapper class for managing "untainted" or trusted strings using the +type system to prevent questionable mixing of ordinary untrusted strings with +untainted ones then passing them to dangerous interfaces. In this way the +security correctness of the code reduces to auditing the direct usages of +dangerous interfaces or promotions of tainted strings to untainted ones. + +3. Encryption of string contents is way beyond the scope of Bstrlib. +Maintaining encrypted string contents in the futile hopes of thwarting things +like using system-level debuggers to examine sensitive string data is likely +to be a wasted effort (imagine a debugger that runs at a higher level than a +virtual processor where the application runs). For more standard encryption +usages, since the bstring contents are simply binary blocks of data, this +should pose no problem for usage with other standard encryption libraries. + +Compatibility +------------- + +The Better String Library is known to compile and function correctly with the +following compilers: + + - Microsoft Visual C++ + - Watcom C/C++ + - Intel's C/C++ compiler (Windows) + - The GNU C/C++ compiler (cygwin and Linux on PPC64) + - Borland C + - Turbo C + +Setting of configuration options should be unnecessary for these compilers +(unless exceptions are being disabled or STLport has been added to WATCOM +C/C++). Bstrlib has been developed with an emphasis on portability. As such +porting it to other compilers should be straight forward. This package +includes a porting guide (called porting.txt) which explains what issues may +exist for porting Bstrlib to different compilers and environments. + +ANSI issues +----------- + +1. The function pointer types bNgetc and bNread have prototypes which are very +similar to, but not exactly the same as fgetc and fread respectively. +Basically the FILE * parameter is replaced by void *. The purpose of this +was to allow one to create other functions with fgetc and fread like +semantics without being tied to ANSI C's file streaming mechanism. I.e., one +could very easily adapt it to sockets, or simply reading a block of memory, +or procedurally generated strings (for fractal generation, for example.) + +The problem is that invoking the functions (bNgetc)fgetc and (bNread)fread is +not technically legal in ANSI C. The reason being that the compiler is only +able to coerce the function pointers themselves into the target type, however +are unable to perform any cast (implicit or otherwise) on the parameters +passed once invoked. I.e., if internally void * and FILE * need some kind of +mechanical coercion, the compiler will not properly perform this conversion +and thus lead to undefined behavior. + +Apparently a platform from Data General called "Eclipse" and another from +Tandem called "NonStop" have a different representation for pointers to bytes +and pointers to words, for example, where coercion via casting is necessary. +(Actual confirmation of the existence of such machines is hard to come by, so +it is prudent to be skeptical about this information.) However, this is not +an issue for any known contemporary platforms. One may conclude that such +platforms are effectively apocryphal even if they do exist. + +To correctly work around this problem to the satisfaction of the ANSI +limitations, one needs to create wrapper functions for fgets and/or +fread with the prototypes of bNgetc and/or bNread respectively which performs +no other action other than to explicitely cast the void * parameter to a +FILE *, and simply pass the remaining parameters straight to the function +pointer call. + +The wrappers themselves are trivial: + + size_t freadWrap (void * buff, size_t esz, size_t eqty, void * parm) { + return fread (buff, esz, eqty, (FILE *) parm); + } + + int fgetcWrap (void * parm) { + return fgetc ((FILE *) parm); + } + +These have not been supplied in bstrlib or bstraux to prevent unnecessary +linking with file I/O functions. + +2. vsnprintf is not available on all compilers. Because of this, the bformat +and bformata functions (and format and formata methods) are not guaranteed to +work properly. For those compilers that don't have vsnprintf, the +BSTRLIB_NOVSNP macro should be set before compiling bstrlib, and the format +functions/method will be disabled. + +The more recent ANSI C standards have specified the required inclusion of a +vsnprintf function. + +3. The bstrlib function names are not unique in the first 6 characters. This +is only an issue for older C compiler environments which do not store more +than 6 characters for function names. + +4. The bsafe module defines macros and function names which are part of the +C library. This simply overrides the definition as expected on all platforms +tested, however it is not sanctioned by the ANSI standard. This module is +clearly optional and should be omitted on platforms which disallow its +undefined semantics. + +In practice the real issue is that some compilers in some modes of operation +can/will inline these standard library functions on a module by module basis +as they appear in each. The linker will thus have no opportunity to override +the implementation of these functions for those cases. This can lead to +inconsistent behaviour of the bsafe module on different platforms and +compilers. + +=============================================================================== + +Comparison with Microsoft's CString class +----------------------------------------- + +Although developed independently, CBStrings have very similar functionality to +Microsoft's CString class. However, the bstring library has significant +advantages over CString: + +1. Bstrlib is a C-library as well as a C++ library (using the C++ wrapper). + + - Thus it is compatible with more programming environments and + available to a wider population of programmers. + +2. The internal structure of a bstring is considered exposed. + + - A single contiguous block of data can be cut into read-only pieces by + simply creating headers, without allocating additional memory to create + reference copies of each of these sub-strings. + - In this way, using bstrings in a totally abstracted way becomes a choice + rather than an imposition. Further this choice can be made differently + at different layers of applications that use it. + +3. Static declaration support precludes the need for constructor + invocation. + + - Allows for static declarations of constant strings that has no + additional constructor overhead. + +4. Bstrlib is not attached to another library. + + - Bstrlib is designed to be easily plugged into any other library + collection, without dependencies on other libraries or paradigms (such + as "MFC".) + +The bstring library also comes with a few additional functions that are not +available in the CString class: + + - bsetstr + - bsplit + - bread + - breplace (this is different from CString::Replace()) + - Writable indexed characters (for example a[i]='x') + +Interestingly, although Microsoft did implement mid$(), left$() and right$() +functional analogues (these are functions from GWBASIC) they seem to have +forgotten that mid$() could be also used to write into the middle of a string. +This functionality exists in Bstrlib with the bsetstr() and breplace() +functions. + +Among the disadvantages of Bstrlib is that there is no special support for +localization or wide characters. Such things are considered beyond the scope +of what bstrings are trying to deliver. CString essentially supports the +older UCS-2 version of Unicode via widechar_t as an application-wide compile +time switch. + +CString's also use built-in mechanisms for ensuring thread safety under all +situations. While this makes writing thread safe code that much easier, this +built-in safety feature has a price -- the inner loops of each CString method +runs in its own critical section (grabbing and releasing a light weight mutex +on every operation.) The usual way to decrease the impact of a critical +section performance penalty is to amortize more operations per critical +section. But since the implementation of CStrings is fixed as a one critical +section per-operation cost, there is no way to leverage this common +performance enhancing idea. + +The search facilities in Bstrlib are comparable to those in MFC's CString +class, though it is missing locale specific collation. But because Bstrlib +is interoperable with C's char buffers, it will allow programmers to write +their own string searching mechanism (such as Boyer-Moore), or be able to +choose from a variety of available existing string searching libraries (such +as those for regular expressions) without difficulty. + +Microsoft used a very non-ANSI conforming trick in its implementation to +allow printf() to use the "%s" specifier to output a CString correctly. This +can be convenient, but it is inherently not portable. CBString requires an +explicit cast, while bstring requires the data member to be dereferenced. +Microsoft's own documentation recommends casting, instead of relying on this +feature. + +Comparison with C++'s std::string +--------------------------------- + +This is the C++ language's standard STL based string class. + +1. There is no C implementation. +2. The [] operator is not bounds checked. +3. Missing a lot of useful functions like printf-like formatting. +4. Some sub-standard std::string implementations (SGI) are necessarily unsafe + to use with multithreading. +5. Limited by STL's std::iostream which in turn is limited by ifstream which + can only take input from files. (Compare to CBStream's API which can take + abstracted input.) +6. Extremely uneven performance across implementations. + +Comparison with ISO C TR 24731 proposal +--------------------------------------- + +Following the ISO C99 standard, Microsoft has proposed a group of C library +extensions which are supposedly "safer and more secure". This proposal is +expected to be adopted by the ISO C standard which follows C99. + +The proposal reveals itself to be very similar to Microsoft's "StrSafe" +library. The functions are basically the same as other standard C library +string functions except that destination parameters are paired with an +additional length parameter of type rsize_t. rsize_t is the same as size_t, +however, the range is checked to make sure its between 1 and RSIZE_MAX. Like +Bstrlib, the functions perform a "parameter check". Unlike Bstrlib, when a +parameter check fails, rather than simply outputing accumulatable error +statuses, they call a user settable global error function handler, and upon +return of control performs no (additional) detrimental action. The proposal +covers basic string functions as well as a few non-reenterable functions +(asctime, ctime, and strtok). + +1. Still based solely on char * buffers (and therefore strlen() and strcat() + is still O(n), and there are no faster streq() comparison functions.) +2. No growable string semantics. +3. Requires manual buffer length synchronization in the source code. +4. No attempt to enhance functionality of the C library. +5. Introduces a new error scenario (strings exceeding RSIZE_MAX length). + +The hope is that by exposing the buffer length requirements there will be +fewer buffer overrun errors. However, the error modes are really just +transformed, rather than removed. The real problem of buffer overflows is +that they all happen as a result of erroneous programming. So forcing +programmers to manually deal with buffer limits, will make them more aware of +the problem but doesn't remove the possibility of erroneous programming. So +a programmer that erroneously mixes up the rsize_t parameters is no better off +from a programmer that introduces potential buffer overflows through other +more typical lapses. So at best this may reduce the rate of erroneous +programming, rather than making any attempt at removing failure modes. + +The error handler can discriminate between types of failures, but does not +take into account any callsite context. So the problem is that the error is +going to be manifest in a piece of code, but there is no pointer to that +code. It would seem that passing in the call site __FILE__, __LINE__ as +parameters would be very useful, but the API clearly doesn't support such a +thing (it would increase code bloat even more than the extra length +parameter does, and would require macro tricks to implement). + +The Bstrlib C API takes the position that error handling needs to be done at +the callsite, and just tries to make it as painless as possible. Furthermore, +error modes are removed by supporting auto-growing strings and aliasing. For +capturing errors in more central code fragments, Bstrlib's C++ API uses +exception handling extensively, which is superior to the leaf-only error +handler approach. + +Comparison with Managed String Library CERT proposal +---------------------------------------------------- + +The main webpage for the managed string library: +http://www.cert.org/secure-coding/managedstring.html + +Robert Seacord at CERT has proposed a C string library that he calls the +"Managed String Library" for C. Like Bstrlib, it introduces a new type +which is called a managed string. The structure of a managed string +(string_m) is like a struct tagbstring but missing the length field. This +internal structure is considered opaque. The length is, like the C standard +library, always computed on the fly by searching for a terminating NUL on +every operation that requires it. So it suffers from every performance +problem that the C standard library suffers from. Interoperating with C +string APIs (like printf, fopen, or anything else that takes a string +parameter) requires copying to additionally allocating buffers that have to +be manually freed -- this makes this library probably slower and more +cumbersome than any other string library in existence. + +The library gives a fully populated error status as the return value of every +string function. The hope is to be able to diagnose all problems +specifically from the return code alone. Comparing this to Bstrlib, which +aways returns one consistent error message, might make it seem that Bstrlib +would be harder to debug; but this is not true. With Bstrlib, if an error +occurs there is always enough information from just knowing there was an error +and examining the parameters to deduce exactly what kind of error has +happened. The managed string library thus gives up nested function calls +while achieving little benefit, while Bstrlib does not. + +One interesting feature that "managed strings" has is the idea of data +sanitization via character set whitelisting. That is to say, a globally +definable filter that makes any attempt to put invalid characters into strings +lead to an error and not modify the string. The author gives the following +example: + + // create valid char set + if (retValue = strcreate_m(&str1, "abc") ) { + fprintf( + stderr, + "Error %d from strcreate_m.\n", + retValue + ); + } + if (retValue = setcharset(str1)) { + fprintf( + stderr, + "Error %d from setcharset().\n", + retValue + ); + } + if (retValue = strcreate_m(&str1, "aabbccabc")) { + fprintf( + stderr, + "Error %d from strcreate_m.\n", + retValue + ); + } + // create string with invalid char set + if (retValue = strcreate_m(&str1, "abbccdabc")) { + fprintf( + stderr, + "Error %d from strcreate_m.\n", + retValue + ); + } + +Which we can compare with a more Bstrlib way of doing things: + + bstring bCreateWithFilter (const char * cstr, const_bstring filter) { + bstring b = bfromcstr (cstr); + if (BSTR_ERR != bninchr (b, filter) && NULL != b) { + fprintf (stderr, "Filter violation.\n"); + bdestroy (b); + b = NULL; + } + return b; + } + + struct tagbstring charFilter = bsStatic ("abc"); + bstring str1 = bCreateWithFilter ("aabbccabc", &charFilter); + bstring str2 = bCreateWithFilter ("aabbccdabc", &charFilter); + +The first thing we should notice is that with the Bstrlib approach you can +have different filters for different strings if necessary. Furthermore, +selecting a charset filter in the Managed String Library is uni-contextual. +That is to say, there can only be one such filter active for the entire +program, which means its usage is not well defined for intermediate library +usage (a library that uses it will interfere with user code that uses it, and +vice versa.) It is also likely to be poorly defined in multi-threading +environments. + +There is also a question as to whether the data sanitization filter is checked +on every operation, or just on creation operations. Since the charset can be +set arbitrarily at run time, it might be set *after* some managed strings have +been created. This would seem to imply that all functions should run this +additional check every time if there is an attempt to enforce this. This +would make things tremendously slow. On the other hand, if it is assumed that +only creates and other operations that take char *'s as input need be checked +because the charset was only supposed to be called once at and before any +other managed string was created, then one can see that its easy to cover +Bstrlib with equivalent functionality via a few wrapper calls such as the +example given above. + +And finally we have to question the value of sanitation in the first place. +For example, for httpd servers, there is generally a requirement that the +URLs parsed have some form that avoids undesirable translation to local file +system filenames or resources. The problem is that the way URLs can be +encoded, it must be completely parsed and translated to know if it is using +certain invalid character combinations. That is to say, merely filtering +each character one at a time is not necessarily the right way to ensure that +a string has safe contents. + +In the article that describes this proposal, it is claimed that it fairly +closely approximates the existing C API semantics. On this point we should +compare this "closeness" with Bstrlib: + + Bstrlib Managed String Library + ------- ---------------------- + +Pointer arithmetic Segment arithmetic N/A + +Use in C Std lib ->data, or bdata{e} getstr_m(x,*) ... free(x) + +String literals bsStatic, bsStaticBlk strcreate_m() + +Transparency Complete None + +Its pretty clear that the semantic mapping from C strings to Bstrlib is fairly +straightforward, and that in general semantic capabilities are the same or +superior in Bstrlib. On the other hand the Managed String Library is either +missing semantics or changes things fairly significantly. + +Comparison with Annexia's c2lib library +--------------------------------------- + +This library is available at: +http://www.annexia.org/freeware/c2lib + +1. Still based solely on char * buffers (and therefore strlen() and strcat() + is still O(n), and there are no faster streq() comparison functions.) + Their suggestion that alternatives which wrap the string data type (such as + bstring does) imposes a difficulty in interoperating with the C langauge's + ordinary C string library is not founded. +2. Introduction of memory (and vector?) abstractions imposes a learning + curve, and some kind of memory usage policy that is outside of the strings + themselves (and therefore must be maintained by the developer.) +3. The API is massive, and filled with all sorts of trivial (pjoin) and + controvertial (pmatch -- regular expression are not sufficiently + standardized, and there is a very large difference in performance between + compiled and non-compiled, REs) functions. Bstrlib takes a decidely + minimal approach -- none of the functionality in c2lib is difficult or + challenging to implement on top of Bstrlib (except the regex stuff, which + is going to be difficult, and controvertial no matter what.) +4. Understanding why c2lib is the way it is pretty much requires a working + knowledge of Perl. bstrlib requires only knowledge of the C string library + while providing just a very select few worthwhile extras. +5. It is attached to a lot of cruft like a matrix math library (that doesn't + include any functions for getting the determinant, eigenvectors, + eigenvalues, the matrix inverse, test for singularity, test for + orthogonality, a grahm schmit orthogonlization, LU decomposition ... I + mean why bother?) + +Convincing a development house to use c2lib is likely quite difficult. It +introduces too much, while not being part of any kind of standards body. The +code must therefore be trusted, or maintained by those that use it. While +bstring offers nothing more on this front, since its so much smaller, covers +far less in terms of scope, and will typically improve string performance, +the barrier to usage should be much smaller. + +Comparison with stralloc/qmail +------------------------------ + +More information about this library can be found here: +http://www.canonical.org/~kragen/stralloc.html or here: +http://cr.yp.to/lib/stralloc.html + +1. Library is very very minimal. A little too minimal. +2. Untargetted source parameters are not declared const. +3. Slightly different expected emphasis (like _cats function which takes an + ordinary C string char buffer as a parameter.) Its clear that the + remainder of the C string library is still required to perform more + useful string operations. + +The struct declaration for their string header is essentially the same as that +for bstring. But its clear that this was a quickly written hack whose goals +are clearly a subset of what Bstrlib supplies. For anyone who is served by +stralloc, Bstrlib is complete substitute that just adds more functionality. + +stralloc actually uses the interesting policy that a NULL data pointer +indicates an empty string. In this way, non-static empty strings can be +declared without construction. This advantage is minimal, since static empty +bstrings can be declared inline without construction, and if the string needs +to be written to it should be constructed from an empty string (or its first +initializer) in any event. + +wxString class +-------------- + +This is the string class used in the wxWindows project. A description of +wxString can be found here: +http://www.wxwindows.org/manuals/2.4.2/wx368.htm#wxstring + +This C++ library is similar to CBString. However, it is littered with +trivial functions (IsAscii, UpperCase, RemoveLast etc.) + +1. There is no C implementation. +2. The memory management strategy is to allocate a bounded fixed amount of + additional space on each resize, meaning that it does not have the + log_2(n) property that Bstrlib has (it will thrash very easily, cause + massive fragmentation in common heap implementations, and can easily be a + common source of performance problems). +3. The library uses a "copy on write" strategy, meaning that it has to deal + with multithreading problems. + +Vstr +---- + +This is a highly orthogonal C string library with an emphasis on +networking/realtime programming. It can be found here: +http://www.and.org/vstr/ + +1. The convoluted internal structure does not contain a '\0' char * compatible + buffer, so interoperability with the C library a non-starter. +2. The API and implementation is very large (owing to its orthogonality) and + can lead to difficulty in understanding its exact functionality. +3. An obvious dependency on gnu tools (confusing make configure step) +4. Uses a reference counting system, meaning that it is not likely to be + thread safe. + +The implementation has an extreme emphasis on performance for nontrivial +actions (adds, inserts and deletes are all constant or roughly O(#operations) +time) following the "zero copy" principle. This trades off performance of +trivial functions (character access, char buffer access/coersion, alias +detection) which becomes significantly slower, as well as incremental +accumulative costs for its searching/parsing functions. Whether or not Vstr +wins any particular performance benchmark will depend a lot on the benchmark, +but it should handily win on some, while losing dreadfully on others. + +The learning curve for Vstr is very steep, and it doesn't come with any +obvious way to build for Windows or other platforms without gnu tools. At +least one mechanism (the iterator) introduces a new undefined scenario +(writing to a Vstr while iterating through it.) Vstr has a very large +footprint, and is very ambitious in its total functionality. Vstr has no C++ +API. + +Vstr usage requires context initialization via vstr_init() which must be run +in a thread-local context. Given the totally reference based architecture +this means that sharing Vstrings across threads is not well defined, or at +least not safe from race conditions. This API is clearly geared to the older +standard of fork() style multitasking in UNIX, and is not safely transportable +to modern shared memory multithreading available in Linux and Windows. There +is no portable external solution making the library thread safe (since it +requires a mutex around each Vstr context -- not each string.) + +In the documentation for this library, a big deal is made of its self hosted +s(n)printf-like function. This is an issue for older compilers that don't +include vsnprintf(), but also an issue because Vstr has a slow conversion to +'\0' terminated char * mechanism. That is to say, using "%s" to format data +that originates from Vstr would be slow without some sort of native function +to do so. Bstrlib sidesteps the issue by relying on what snprintf-like +functionality does exist and having a high performance conversion to a char * +compatible string so that "%s" can be used directly. + +Str Library +----------- + +This is a fairly extensive string library, that includes full unicode support +and targetted at the goal of out performing MFC and STL. The architecture, +similarly to MFC's CStrings, is a copy on write reference counting mechanism. + +http://www.utilitycode.com/str/default.aspx + +1. Commercial. +2. C++ only. + +This library, like Vstr, uses a ref counting system. There is only so deeply +I can analyze it, since I don't have a license for it. However, performance +improvements over MFC's and STL, doesn't seem like a sufficient reason to +move your source base to it. For example, in the future, Microsoft may +improve the performance CString. + +It should be pointed out that performance testing of Bstrlib has indicated +that its relative performance advantage versus MFC's CString and STL's +std::string is at least as high as that for the Str library. + +libmib astrings +--------------- + +A handful of functional extensions to the C library that add dynamic string +functionality. +http://www.mibsoftware.com/libmib/astring/ + +This package basically references strings through char ** pointers and assumes +they are pointing to the top of an allocated heap entry (or NULL, in which +case memory will be newly allocated from the heap.) So its still up to user +to mix and match the older C string functions with these functions whenever +pointer arithmetic is used (i.e., there is no leveraging of the type system +to assert semantic differences between references and base strings as Bstrlib +does since no new types are introduced.) Unlike Bstrlib, exact string length +meta data is not stored, thus requiring a strlen() call on *every* string +writing operation. The library is very small, covering only a handful of C's +functions. + +While this is better than nothing, it is clearly slower than even the +standard C library, less safe and less functional than Bstrlib. + +To explain the advantage of using libmib, their website shows an example of +how dangerous C code: + + char buf[256]; + char *pszExtraPath = ";/usr/local/bin"; + + strcpy(buf,getenv("PATH")); /* oops! could overrun! */ + strcat(buf,pszExtraPath); /* Could overrun as well! */ + + printf("Checking...%s\n",buf); /* Some printfs overrun too! */ + +is avoided using libmib: + + char *pasz = 0; /* Must initialize to 0 */ + char *paszOut = 0; + char *pszExtraPath = ";/usr/local/bin"; + + if (!astrcpy(&pasz,getenv("PATH"))) /* malloc error */ exit(-1); + if (!astrcat(&pasz,pszExtraPath)) /* malloc error */ exit(-1); + + /* Finally, a "limitless" printf! we can use */ + asprintf(&paszOut,"Checking...%s\n",pasz);fputs(paszOut,stdout); + + astrfree(&pasz); /* Can use free(pasz) also. */ + astrfree(&paszOut); + +However, compare this to Bstrlib: + + bstring b, out; + + bcatcstr (b = bfromcstr (getenv ("PATH")), ";/usr/local/bin"); + out = bformat ("Checking...%s\n", bdatae (b, "<Out of memory>")); + /* if (out && b) */ fputs (bdatae (out, "<Out of memory>"), stdout); + bdestroy (b); + bdestroy (out); + +Besides being shorter, we can see that error handling can be deferred right +to the very end. Also, unlike the above two versions, if getenv() returns +with NULL, the Bstrlib version will not exhibit undefined behavior. +Initialization starts with the relevant content rather than an extra +autoinitialization step. + +libclc +------ + +An attempt to add to the standard C library with a number of common useful +functions, including additional string functions. +http://libclc.sourceforge.net/ + +1. Uses standard char * buffer, and adopts C 99's usage of "restrict" to pass + the responsibility to guard against aliasing to the programmer. +2. Adds no safety or memory management whatsoever. +3. Most of the supplied string functions are completely trivial. + +The goals of libclc and Bstrlib are clearly quite different. + +fireString +---------- + +http://firestuff.org/ + +1. Uses standard char * buffer, and adopts C 99's usage of "restrict" to pass + the responsibility to guard against aliasing to the programmer. +2. Mixes char * and length wrapped buffers (estr) functions, doubling the API + size, with safety limited to only half of the functions. + +Firestring was originally just a wrapper of char * functionality with extra +length parameters. However, it has been augmented with the inclusion of the +estr type which has similar functionality to stralloc. But firestring does +not nearly cover the functional scope of Bstrlib. + +Safe C String Library +--------------------- + +A library written for the purpose of increasing safety and power to C's string +handling capabilities. +http://www.zork.org/safestr/safestr.html + +1. While the safestr_* functions are safe in of themselves, interoperating + with char * string has dangerous unsafe modes of operation. +2. The architecture of safestr's causes the base pointer to change. Thus, + its not practical/safe to store a safestr in multiple locations if any + single instance can be manipulated. +3. Dependent on an additional error handling library. +4. Uses reference counting, meaning that it is either not thread safe or + slow and not portable. + +I think the idea of reallocating (and hence potentially changing) the base +pointer is a serious design flaw that is fatal to this architecture. True +safety is obtained by having automatic handling of all common scenarios +without creating implicit constraints on the user. + +Because of its automatic temporary clean up system, it cannot use "const" +semantics on input arguments. Interesting anomolies such as: + + safestr_t s, t; + s = safestr_replace (t = SAFESTR_TEMP ("This is a test"), + SAFESTR_TEMP (" "), SAFESTR_TEMP (".")); + /* t is now undefined. */ + +are possible. If one defines a function which takes a safestr_t as a +parameter, then the function would not know whether or not the safestr_t is +defined after it passes it to a safestr library function. The author +recommended method for working around this problem is to examine the +attributes of the safestr_t within the function which is to modify any of +its parameters and play games with its reference count. I think, therefore, +that the whole SAFESTR_TEMP idea is also fatally broken. + +The library implements immutability, optional non-resizability, and a "trust" +flag. This trust flag is interesting, and suggests that applying any +arbitrary sequence of safestr_* function calls on any set of trusted strings +will result in a trusted string. It seems to me, however, that if one wanted +to implement a trusted string semantic, one might do so by actually creating +a different *type* and only implement the subset of string functions that are +deemed safe (i.e., user input would be excluded, for example.) This, in +essence, would allow the compiler to enforce trust propogation at compile +time rather than run time. Non-resizability is also interesting, however, +it seems marginal (i.e., to want a string that cannot be resized, yet can be +modified and yet where a fixed sized buffer is undesirable.) + +=============================================================================== + +Examples +-------- + + Dumping a line numbered file: + + FILE * fp; + int i, ret; + struct bstrList * lines; + struct tagbstring prefix = bsStatic ("-> "); + + if (NULL != (fp = fopen ("bstrlib.txt", "rb"))) { + bstring b = bread ((bNread) fread, fp); + fclose (fp); + if (NULL != (lines = bsplit (b, '\n'))) { + for (i=0; i < lines->qty; i++) { + binsert (lines->entry[i], 0, &prefix, '?'); + printf ("%04d: %s\n", i, bdatae (lines->entry[i], "NULL")); + } + bstrListDestroy (lines); + } + bdestroy (b); + } + +For numerous other examples, see bstraux.c, bstraux.h and the example archive. + +=============================================================================== + +License +------- + +The Better String Library is available under either the 3 clause BSD license +(see the accompanying license.txt) or the Gnu Public License version 2 (see +the accompanying gpl.txt) at the option of the user. + +=============================================================================== + +Acknowledgements +---------------- + +The following individuals have made significant contributions to the design +and testing of the Better String Library: + +Bjorn Augestad +Clint Olsen +Darryl Bleau +Fabian Cenedese +Graham Wideman +Ignacio Burgueno +International Business Machines Corporation +Ira Mica +John Kortink +Manuel Woelker +Marcel van Kervinck +Michael Hsieh +Richard A.

You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software.

To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this.

At the heart of the bstring library +is the management of "bstring"s which are a significant improvement over '\0' +terminated char buffers. See the accompanying documenation file bstrlib.txt +for more information. + +=============================================================================== + +Identifying the Compiler +------------------------ + +Bstrlib has been tested on the following compilers: + + Microsoft Visual C++ + Watcom C/C++ (32 bit flat) + Intel's C/C++ compiler (on Windows) + The GNU C/C++ compiler (on Windows/Linux on x86 and PPC64) + Borland C++ + Turbo C + +There are slight differences in these compilers which requires slight +differences in the implementation of Bstrlib. These are accomodated in the +same sources using #ifdef/#if defined() on compiler specific macros. To +port Bstrlib to a new compiler not listed above, it is recommended that the +same strategy be followed. If you are unaware of the compiler specific +identifying preprocessor macro for your compiler you might find it here: + +http://predef.sourceforge.net/precomp.html + +Note that Intel C/C++ on Windows sets the Microsoft identifier: _MSC_VER. + +16-bit vs. 32-bit vs. 64-bit Systems +------------------------------------ + +Bstrlib has been architected to deal with strings of length between 0 and +INT_MAX (inclusive). Since the values of int are never higher than size_t +there will be no issue here. Note that on most 64-bit systems int is 32-bit. + +Dependency on The C-Library +--------------------------- + +Bstrlib uses the functions memcpy, memmove, malloc, realloc, free and +vsnprintf. Many free standing C compiler implementations that have a mode in +which the C library is not available will typically not include these +functions which will make porting Bstrlib to it onerous. Bstrlib is not +designed for such bare bones compiler environments. This usually includes +compilers that target ROM environments. + +Porting Issues +-------------- + +Bstrlib has been written completely in ANSI/ISO C and ISO C++, however, there +are still a few porting issues. These are described below. + +1. The vsnprintf () function. + +Unfortunately, the earlier ANSI/ISO C standards did not include this function. +If the compiler of interest does not support this function then the +BSTRLIB_NOVSNP should be defined via something like: + + #if !defined (BSTRLIB_VSNP_OK) && !defined (BSTRLIB_NOVSNP) + # if defined (__TURBOC__) || defined (__COMPILERVENDORSPECIFICMACRO__) + # define BSTRLIB_NOVSNP + # endif + #endif + +which appears at the top of bstrlib.h. Note that the bformat(a) functions +will not be declared or implemented if the BSTRLIB_NOVSNP macro is set. If +the compiler has renamed vsnprintf() to some other named function, then +search for the definition of the exvsnprintf macro in bstrlib.c file and be +sure its defined appropriately: + + #if defined (__COMPILERVENDORSPECIFICMACRO__) + # define exvsnprintf(r,b,n,f,a) {r=__compiler_specific_vsnprintf(b,n,f,a);} + #else + # define exvsnprintf(r,b,n,f,a) {r=vsnprintf(b,n,f,a);} + #endif + +Take notice of the return value being captured in the variable r. It is +assumed that r exceeds n if and only if the underlying vsnprintf function has +determined what the true maximal output length would be for output if the +buffer were large enough to hold it. Non-modern implementations must output a +lesser number (the macro can and should be modified to ensure this). + +2. Weak C++ compiler. + +C++ is a much more complicated language to implement than C. This has lead +to varying quality of compiler implementations. The weaknesses isolated in +the initial ports are inclusion of the Standard Template Library, +std::iostream and exception handling. By default it is assumed that the C++ +compiler supports all of these things correctly. If your compiler does not +support one or more of these define the corresponding macro: + + BSTRLIB_CANNOT_USE_STL + BSTRLIB_CANNOT_USE_IOSTREAM + BSTRLIB_DOESNT_THROW_EXCEPTIONS + +The compiler specific detected macro should be defined at the top of +bstrwrap.h in the Configuration defines section. Note that these disabling +macros can be overrided with the associated enabling macro if a subsequent +version of the compiler gains support. (For example, its possible to rig +up STLport to provide STL support for WATCOM C/C++, so -DBSTRLIB_CAN_USE_STL +can be passed in as a compiler option.) + +3. The bsafe module, and reserved words. + +The bsafe module is in gross violation of the ANSI/ISO C standard in the +sense that it redefines what could be implemented as reserved words on a +given compiler. The typical problem is that a compiler may inline some of the +functions and thus not be properly overridden by the definitions in the bsafe +module. It is also possible that a compiler may prohibit the redefinitions in +the bsafe module. Compiler specific action will be required to deal with +these situations. + +Platform Specific Files +----------------------- + +The makefiles for the examples are basically setup of for particular +environments for each platform. In general these makefiles are not portable +and should be constructed as necessary from scratch for each platform. + +Testing a port +-------------- + +To test that a port compiles correctly do the following: + +1. Build a sample project that includes the bstrlib, bstraux, bstrwrap, and + bsafe modules. +2. Compile bstest against the bstrlib module. +3. Run bstest and ensure that 0 errors are reported. +4. Compile test against the bstrlib and bstrwrap modules. +5. Run test and ensure that 0 errors are reported. +6. Compile each of the examples (except for the "re" example, which may be + complicated and is not a real test of bstrlib and except for the mfcbench + example which is Windows specific.) +7. Run each of the examples. + +The builds must have 0 errors, and should have the absolute minimum number of +warnings (in most cases can be reduced to 0.) The result of execution should +be essentially identical on each platform. + +Performance +----------- + +Different CPU and compilers have different capabilities in terms of +performance. It is possible for Bstrlib to assume performance +characteristics that a platform doesn't have (since it was primarily +developed on just one platform). The goal of Bstrlib is to provide very good +performance on all platforms regardless of this but without resorting to +extreme measures (such as using assembly language, or non-portable intrinsics +or library extensions.) + +There are two performance benchmarks that can be found in the example/ +directory. They are: cbench.c and cppbench.cpp. These are variations and +expansions of a benchmark for another string library. They don't cover all +string functionality, but do include the most basic functions which will be +common in most string manipulation kernels. + +............................................................................... + +Feedback +-------- + +In all cases, you may email issues found to the primary author of Bstrlib at +the email address: [email protected] + +=============================================================================== diff --git a/build/tools/HLSLcc/May_2014/src/cbstring/security.txt b/build/tools/HLSLcc/May_2014/src/cbstring/security.txt new file mode 100644 index 0000000..9761409 --- /dev/null +++ b/build/tools/HLSLcc/May_2014/src/cbstring/security.txt @@ -0,0 +1,221 @@ +Better String library Security Statement +---------------------------------------- + +by Paul Hsieh + +=============================================================================== + +Introduction +------------ + +The Better String library (hereafter referred to as Bstrlib) is an attempt to +provide improved string processing functionality to the C and C++ languages. +At the heart of the Bstrlib is the management of "bstring"s which are a +significant improvement over '\0' terminated char buffers.

Nevertheless a good faith effort has been made to minimize +such flaws in Bstrlib. Also, use of Bstrlib by itself will not make an +application secure or free from implementation failures. However, it is the +author's conviction that use of Bstrlib can greatly facilitate the creation +of software meeting the highest possible standards of security. + +Part of the reason why this document has been created, is for the purpose of +security auditing, or the creation of further "Statements on Security" for +software that is created that uses Bstrlib. An auditor may check the claims +below against Bstrlib, and use this as a basis for analysis of software which +uses Bstrlib. + +=============================================================================== + +Statement on Security +--------------------- + +This is a document intended to give consumers of the Better String Library +who are interested in security an idea of where the Better String Library +stands on various security issues. Any deviation observed in the actual +library itself from the descriptions below should be considered an +implementation error, not a design flaw. + +This statement is not an analytical proof of correctness or an outline of one +but rather an assertion similar to a scientific claim or hypothesis. By use, +testing and open independent examination (otherwise known as scientific +falsifiability), the credibility of the claims made below can rise to the +level of an established theory. + +Common security issues: +....................... + +1. Buffer Overflows + +The Bstrlib API allows the programmer a way to deal with strings without +having to deal with the buffers containing them. Ordinary usage of the +Bstrlib API itself makes buffer overflows impossible. + +Furthermore, the Bstrlib API has a superset of basic string functionality as +compared to the C library's char * functions, C++'s std::string class and +Microsoft's MFC based CString class. It also has abstracted mechanisms for +dealing with IO. This is important as it gives developers a way of migrating +all their code from a functionality point of view. + +2. Memory size overflow/wrap around attack + +Bstrlib is, by design, impervious to memory size overflow attacks. The +reason is it is resiliant to length overflows is that bstring lengths are +bounded above by INT_MAX, instead of ~(size_t)0. So length addition +overflows cause a wrap around of the integer value making them negative +causing balloc() to fail before an erroneous operation can occurr. Attempted +conversions of char * strings which may have lengths greater than INT_MAX are +detected and the conversion is aborted. + +It is unknown if this property holds on machines that don't represent +integers as 2s complement. It is recommended that Bstrlib be carefully +auditted by anyone using a system which is not 2s complement based. + +3. Constant string protection + +Bstrlib implements runtime enforced constant and read-only string semantics. +I.e., bstrings which are declared as constant via the bsStatic() macro cannot +be modified or deallocated directly through the Bstrlib API, and this cannot +be subverted by casting or other type coercion. This is independent of the +use of the const_bstring data type. + +The Bstrlib C API uses the type const_bstring to specify bstring parameters +whose contents do not change. Although the C language cannot enforce this, +this is nevertheless guaranteed by the implementation of the Bstrlib library +of C functions. The C++ API enforces the const attribute on CBString types +correctly. + +4. Aliased bstring support + +Bstrlib detects and supports aliased parameter management throughout the API. +The kind of aliasing that is allowed is the one where pointers of the same +basic type may be pointing to overlapping objects (this is the assumption the +ANSI C99 specification makes.) Each function behaves as if all read-only +parameters were copied to temporaries which are used in their stead before +the function is enacted (it rarely actually does this). No function in the +Bstrlib uses the "restrict" parameter attribute from the ANSI C99 +specification. + +5. Information leaking + +In bstraux.h, using the semantically equivalent macros bSecureDestroy() and +bSecureWriteProtect() in place of bdestroy() and bwriteprotect() respectively +will ensure that stale data does not linger in the heap's free space after +strings have been released back to memory. Created bstrings or CBStrings +are not linked to anything external to themselves, and thus cannot expose +deterministic data leaking. If a bstring is resized, the preimage may exist +as a copy that is released to the heap. Thus for sensitive data, the bstring +should be sufficiently presized before manipulated so that it is not resized. +bSecureInput() has been supplied in bstraux.c, which can be used to obtain +input securely without any risk of leaving any part of the input image in the +heap except for the allocated bstring that is returned. + +6. Memory leaking + +Bstrlib can be built using memdbg.h enabled via the BSTRLIB_MEMORY_DEBUG +macro. User generated definitions for malloc, realloc and free can then be +supplied which can implement special strategies for memory corruption +detection or memory leaking. Otherwise, bstrlib does not do anything out of +the ordinary to attempt to deal with the standard problem of memory leaking +(i.e., losing references to allocated memory) when programming in the C and +C++ languages. However, it does not compound the problem any more than exists +either, as it doesn't have any intrinsic inescapable leaks in it. Bstrlib +does not preclude the use of automatic garbage collection mechanisms such as +the Boehm garbage collector. + +7. Encryption + +Bstrlib does not present any built-in encryption mechanism. However, it +supports full binary contents in its data buffers, so any standard block +based encryption mechanism can make direct use of bstrings/CBStrings for +buffer management. + +8. Double freeing + +Freeing a pointer that is already free is an extremely rare, but nevertheless +a potentially ruthlessly corrupting operation (its possible to cause Win 98 to +reboot, by calling free mulitiple times on already freed data using the WATCOM +CRT.) Bstrlib invalidates the bstring header data before freeing, so that in +many cases a double free will be detected and an error will be reported +(though this behaviour is not guaranteed and should not be relied on). + +Using bstrFree pervasively (instead of bdestroy) can lead to somewhat +improved invalid free avoidance (it is completely safe whenever bstring +instances are only stored in unique variables). For example: + + struct tagbstring hw = bsStatic ("Hello, world"); + bstring cpHw = bstrcpy (&hw); + + #ifdef NOT_QUITE_AS_SAFE + bdestroy (cpHw); /* Never fail */ + bdestroy (cpHw); /* Error sometimes detected at runtime */ + bdestroy (&hw); /* Error detected at run time */ + #else + bstrFree (cpHw); /* Never fail */ + bstrFree (cpHw); /* Will do nothing */ + bstrFree (&hw); /* Will lead to a compile time error */ + #endif + +9. Resource based denial of service + +bSecureInput() has been supplied in bstraux.c. It has an optional upper limit +for input length. But unlike fgets(), it is also easily determined if the +buffer has been truncated early. In this way, a program can set an upper limit +on input sizes while still allowing for implementing context specific +truncation semantics (i.e., does the program consume but dump the extra +input, or does it consume it in later inputs?) + +10. Mixing char *'s and bstrings + +The bstring and char * representations are not identical. So there is a risk +when converting back and forth that data may lost. Essentially bstrings can +contain '\0' as a valid non-terminating character, while char * strings +cannot and in fact must use the character as a terminator. The risk of data +loss is very low, since: + + A) the simple method of only using bstrings in a char * semantically + compatible way is both easy to achieve and pervasively supported. + B) obtaining '\0' content in a string is either deliberate or indicative + of another, likely more serious problem in the code. + C) the library comes with various functions which deal with this issue + (namely: bfromcstr(), bstr2cstr (), and bSetCstrChar ()) + +Marginal security issues: +......................... + +11. 8-bit versus 9-bit portability + +Bstrlib uses CHAR_BIT and other limits.h constants to the maximum extent +possible to avoid portability problems. However, Bstrlib has not been tested +on any system that does not represent char as 8-bits. So whether or not it +works on 9-bit systems is an open question. It is recommended that Bstrlib be +carefully auditted by anyone using a system in which CHAR_BIT is not 8. + +12. EBCDIC/ASCII/UTF-8 data representation attacks. + +Bstrlib uses ctype.h functions to ensure that it remains portable to non- +ASCII systems. It also checks range to make sure it is well defined even for +data that ANSI does not define for the ctype functions. + +Obscure issues: +............... + +13.
