Previously, our use of abort() would break anywhere that we didn't
include stdlib.h. This was especially troublesome in case where
tor_assert_nonfatal() was used with ALL_BUGS_ARE_FATAL, since that
one seldom gets tested.
As an alternative, we could have just made this header include
stdlib.h. But that seems bloaty.
Fixes bug 30189; bugfix on 0.3.4.1-alpha.
In 9c132a5f9e we replaced "buf" with a pointer and replaced
one instance of snprintf with asprintf -- but there was still one
snprintf left over, being crashy.
Fixes bug 29967; bug not in any released Tor. This is CID 1444262.
We already do this in our log_debug() macro, but there are times
when we'd like to avoid allocating or precomputing something that we
are only going to log if debugging is on.
Our previous definition implied that code would never keep running
if a BUG occurred (which it does), and that BUG(x) might be true
even if x was false (which it can't be).
Closes ticket 26890. Bugfix on 0.3.1.4-alpha.
That place is git-revision.c; git-revision.c now lives in lib/log.
Also fix the compilation rules so that all object files that need
micro-revision.i depend on it.
Fun fact: these files used to be called log.[ch] until we ran into
conflicts with systems having a log.h file. But now that we always
include "lib/log/log.h", we should be fine.
The smartlist_core library now contains only the parts of smartlists
that are needed for the logging library. This resolves the
circularity between "container" and "log".
The "containers" library still uses the logging code, and has the
higher-level smartlist functions.
This patch:
- introduces an fdio module for low-level fd functions that don't
need to log.
- moves the responsibility for opening files outside of torlog.c,
so it won't need to call tor_open_cloexec.
The locking code gets its own module, since it's more fundamental
than the higher-level locking code.
Extracting the logging code was the whole point here. :)
