libglusterfs (timer): race conditions, illegal mem access, mem leak

2016-06-01T13:50:13+00:00

While investigating gfapi memory consumption with valgrind, valgrind
reported several memory access issues.

Also see the timer 'registry' being recreated (shortly) after being
freed during teardown due to the way it's currently written.

Passing ctx as data to gf_timer_proc() is prone to memory access
issues if ctx is freed before gf_timer_proc() terminates. (And in
fact this does happen, at least in valgrind.) gf_timer_proc() doesn't
need ctx for anything, it only needs ctx->timer, so just pass that.

Nothing ever calls gf_timer_registry_init(). Nothing outside of
timer.c that is. Making it and gf_timer_proc() static.

all: reduce "inline" usage

2015-09-01T11:55:15+00:00

There are three kinds of inline functions: plain inline, extern inline,
and static inline.  All three have been removed from .c files, except
those in "contrib" which aren't our problem.  Inlines in .h files, which
are overwhelmingly "static inline" already, have generally been left
alone.  Over time we should be able to "lower" these into .c files, but
that has to be done in a case-by-case fashion requiring more manual
effort.  This part was easy to do automatically without (as far as I can
tell) any ill effect.

In the process, several pieces of dead code were flagged by the
compiler, and were removed.

build: do not #include "config.h" in each file

2015-05-29T12:43:17+00:00

Instead of including config.h in each file, and have the additional
config.h included from the compiler commandline (-include option).

When a .c file tests for a certain #define, and config.h was not
included, incorrect assumtions were made. With this change, it can not
happen again.

libgfapi, timer: Fix a crash seen in timer when glfs_fini was invoked.

2015-03-18T05:42:12+00:00

The crash is seen when, glfs_init failed for some reason
and glfs_fini was called for cleaning up the partial initialization.

The fix is in two folds:

1. In timer store and restore the THIS, previously
   it was being overwritten.
2. In glfs_free_from_ctx() and glfs_fini() check for
   NULL before destroying.
