getmemoryinfo
Returns an object containing information about memory usage.
Result:
{
"locked": { (json object) Information about locked memory manager
"used": xxxxx, (numeric) Number of bytes used
"free": xxxxx, (numeric) Number of bytes available in current arenas
"total": xxxxxxx, (numeric) Total number of bytes managed
"locked": xxxxxx, (numeric) Amount of bytes that succeeded locking. If this number is smaller than total, locking pages failed at some point and key data could be swapped to disk.
}
}
Examples:
> bitcoin-cli getmemoryinfo
> curl --user myusername --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getmemoryinfo", "params": [] }' -H 'content-type: text/plain;' http://127.0.0.1:8332/

Add a pool for locked memory chunks, replacing LockedPageManager.
This is something I've been wanting to do for a long time. The current
approach of locking objects where they happen to be on the stack or heap
in-place causes a lot of mlock/munlock system call overhead, slowing
down any handling of keys.
Also locked memory is a limited resource on many operating systems (and
using a lot of it bogs down the system), so the previous approach of
locking every page that may contain any key information (but also other
information) is wasteful.

Replace these with vectors allocated from the secure allocator.
This avoids mlock syscall churn on stack pages, as well as makes
it possible to get rid of these functions.
Please review this commit and the previous one carefully that
no `sizeof(vectortype)` remains in the memcpys and memcmps usage
(ick!), and `.data()` or `&vec[x]` is used as appropriate instead of
&vec.

| | | | | | | | | | | | | |
Change CCrypter to use vectors with secure allocator instead of buffers
on in the object itself which will end up on the stack. This avoids
having to call LockedPageManager to lock stack memory pages to prevent the
memory from being swapped to disk. This is wasteful.

This splits the output comparison for `bitcoin-tx` into two steps:
- First, check for data mismatch, parsing the data as json or hex
depending on the extension of the output file
- Then, check if the literal string matches
For either of these cases give a different error.
This prevents wild goose chases when e.g. a trailing space doesn't match
exactly, and makes sure that both test output and examples are valid
data of the purported format.

The consistency is helpful for gauging Gitian build progress. Right now it's necessary to remember which platform builds in which order, which can be confusing if you're attempting to get a quick idea of how far along your builds are.

fa1c3c2 [net] Remove assert(nMaxInbound > 0) (MarcoFalke)

nMaxInbound might very well be 0 or -1, if the user prefers to keep
a small number of maxconnections.
Note: nMaxInbound of -1 means that the user set maxconnections
to 8 or less, but we still want to keep an additional slot for
the feeler connection.

> This new feature is enabled by default if Bitcoin Core is listening, and a connection to Tor can be made. It can be configured with the -listenonion, -torcontrol and -torpassword settings. To show verbose debugging information, pass -debug=tor.
But it is correct to say that the feature is enabled *regardless* of whether a connection to Tor can be made.
I propose to clarify that so that users can eliminate these in their logs (when `listen=1` and no Tor).
And I think it's okay to clarify about the `listen` option, because on several occasions when I read this before I always assumed `listening` meant `server=1` which cost me a lot of time in troubleshooting.

dfe7906 Add missing cs_main lock to ::GETBLOCKTXN processing (Matt Corallo)
|
| | | | | | | | | | | |
| | | | | | | | | | |

| | | | | | | | | | |
| | | | | | | | | | |
| | | | | | | | | | |
| | | | | | | | | | | |
Note that this is not a major issue as, in order for the missing
lock to cause issues, you have to receive a GETBLOCKTXN message
while reindexing, adding a block header via RPC, etc, which results
in either a table rehash or an insert into the bucket which you are
currently looking at.
