* Introduce str_slice runtime functionBrian Anderson2011-05-112-0/+19
| | | | | | | This reduces the time to execute the new lib-str tests from 1:40ish to a few seconds and will eventually allow the full lib-sha1 test to run in a reasonable amount of time. XFAIL lib-str in stage0 - it will run very slowly until the next snapshot.

* Change the setup so that rust_activate_glue returns to rust_exit_task_glueRafael Ávila de Espíndola2011-05-051-38/+19
| | | | | | | | | | | and rust_exit_task_glue calls the rust main. This is simpler since we only need to setup one frame. It also matches what ld.so does, so gdb is happy and stops a backtrace at rust_exit_task_glue instead of continuing past whatever function happened to be before rust_exit_task_glue is the object file. This is the rt part and should be merged after the rust0 part.

* Mark valgrind's _qzz_res as unused to silence warnings on gcc 4.6.Ralph Giles2011-05-052-18/+18
| | | | | | | | | | | This applies c11675 by Julian Seward from valgrind trunk (svn://svn.valgrind.org/valgrind/trunk) to rustrt's included copies of memcheck.h and valgrind.h, effectively backporting the fix from the unreleased 3.6.2. The commit simply applies the gcc 'unused' attribute to the relevant declarations. This change allows compilation of the runtime code under gcc 4.6 with -Werror, as the makefile currently requests.

| | | | | | | | | | | duplication, but we will hopefully drop the rustboot one soon. This is also a preparation for changing the rustc one to have the activate glue return to the exit glue which will then call the main function. This (returning to the function that calls main) matches what happens when loader stats a program or a new thread. It lets gdb produce good backtraces and should help with EH too.

* Overhaul logging system in runtimeMarijn Haverbeke2011-04-1923-633/+459
| | | | | | | | | | | | | | See https://github.com/graydon/rust/wiki/Logging-vision The runtime logging categories are now treated in the same way as modules in compiled code. Each domain now has a log_lvl that can be used to restrict the logging from that domain (will be used to allow logging to be restricted to a single domain). Features dropped (can be brought back to life if there is interest): - Logger indentation - Multiple categories per log statement - I possibly broke some of the color code -- it confuses me

* Temporarily turn off logging initializationMarijn Haverbeke2011-04-181-3/+4
| | | | | Will be restored as soon as I find a way for the runtime to figure out whether it is on rustboot or rustc.
* Update foregoing patches to leave rust_crate alone.Marijn Haverbeke2011-04-185-93/+89
| | | | | | | | | Apparently it can't live in the main binary, since on non-Linux platforms, dynamics libs won't find symbols in the binary. This removes the crate_map pointer from rust_crate again, and instead passes it as an extra argument to rust_start. Rustboot doesn't pass this argument, but supposedly that's okay as long as we don't actually use it on that platform.
* Make log the log level configurable per moduleMarijn Haverbeke2011-04-184-2/+95
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This overloads the meaning of RUST_LOG to also allow 'module.submodule' or 'module.somethingelse=2' forms. The first turn on all logging for a module (loglevel 3), the second sets its loglevel to 2. Log levels are: 0: Show only errors 1: Errors and warnings 2: Errors, warnings, and notes 3: Everything, including debug logging Right now, since we only have one 'log' operation, everything happens at level 1 (warning), so the only meaningful thing that can be done with the new RUST_LOG support is disable logging (=0) for some modules. TODOS: * Language support for logging at a specific level * Also add a log level field to tasks, query the current task as well as the current module before logging (log if one of them allows it) * Revise the C logging API to conform to this set-up (globals for per-module log level, query the task level before logging, stop using a global mask) Implementation notes: Crates now contain two extra data structures. A 'module map' that contains names and pointers to the module-log-level globals for each module in the crate that logs, and a 'crate map' that points at the crate's module map, as well as at the crate maps of all external crates it depends on. These are walked by the runtime (in rust_crate.cpp) to set the currect log levels based on RUST_LOG. These module log globals are allocated as-needed whenever a log expression is encountered, and their location is hard-coded into the logging code, which compares the current level to the log statement's level, and skips over all logging code when it is lower.
