* libglusterfs (timer): race conditions, illegal mem access, mem leakKaleb S KEITHLEY2016-06-081-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. backport mainline: > http://review.gluster.org/14247 > BUG: 1333925 Change-Id: Ia28454dda0cf0de2fec94d76441d98c3927a906a BUG: 1342620 Signed-off-by: Kaleb S KEITHLEY <kkeithle@redhat.com> Reviewed-on: http://review.gluster.org/14644 Smoke: Gluster Build System <jenkins@build.gluster.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.com>
* build: do not #include "config.h" in each fileNiels de Vos2015-05-291-5/+0
| | | | | | | | | | | | | | | | | | 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.

* uss: disable memory accounting for the snapshot daemonRaghavendra Bhat2015-01-281-1/+2
| | | | | | | | | | | | | | | | | | * Bring in option to disable memory accounting for a glusterfs process This reverses the changes done by the commit 7fba3a88f1ced610eca0c23516a1e720d75160cd. * Change the key from "memory-accounting" to "no-memory-accounting", as by default all the glusterfs process enable memory accounting now. So to disable memory accounting for some process, "no-mem-accounting" argument has to be passed.

| | | | | | | | | | | | | | | | memory accounting are constant time operations which involve a few pointer dereferences and integer increments (no loops or searches etc.) benefits of having memory usage info outweigh the minor accounting overheads Change-Id: If9bc6db5ffd0e00f0fd64b2f6eed094bf3543996 BUG: 1089216 Signed-off-by: Anand Avati <avati@redhat.com> Reviewed-on: http://review.gluster.org/7543 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Harshavardhana <harsha@harshavardhana.net>

* glusterfs_ctx_t: un-globalize the filesystem contextAnand Avati2012-07-171-0/+47
So far there has been a global glusterfs_ctx_t object which represents the running instance of the filesystem (client or server). It contains the various graphs, connection to the management daemon over which new graphs are obtained, calls stacks issued on this filesystem, and a bunch of such things. With the introduction of libgfapi, it is no more true that there will be only one filesystem context in a process. Applications can be written to use libgfapi and obtain serveral instances of different filesystems/volumes in the same process. This involves messy untangling of assumptions inside libglusterfs that there would only be one global glusterfs_ctx_t and offload that assumption to glusterfsd/ and cli/ (where it is true).
