* build: export minimum symbols from xlators for correct resolutionKaleb S KEITHLEY2015-12-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | Revisiting http://review.gluster.org/#/c/11814/, which unintentionally introduced warnings from libtool about the xlator .so names. According to [1], the -module option must appear in the Makefile.am file(s); if -module is defined in a macro, e.g. in configure(.ac), then libtool will not recognize that this is a module and will emit a warning.

* build: export minimum symbols from xlators for correct resolutionKaleb S. KEITHLEY2015-09-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | We've been lucky that we haven't had any symbol collisions until now. Now we have a collision between the snapview-client's svc_lookup() and libntirpc's svc_lookup() with nfs-ganesha's FSAL_GLUSTER and libgfapi. As a short term solution all the snapview-client's FOP methods were changed to static scope. See http://review.gluster.org/11805. This works in snapview-client because all the FOP methods are defined in a single source file. This solution doesn't work for other xlators with FOP methods defined in multiple source files. To address this we link with libtool's '-export-symbols $symbol-file' (a wrapper around `ld --version-script ...` --- on linux anyway) and only export the minimum required symbols from the xlator sharedlib. N.B. the libtool man page says that the symbol file should be named foo.sym, thus the rename of *.exports to *.sym. While foo.exports worked, we will follow the documentation. Signed-off-by: Kaleb S.

* cluster/ec: Add self-heal-daemon command handlersPranith Kumar K2015-03-091-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces the changes required in ec xlator to handle index/full heal. Index healer threads: Ec xlator start an index healer thread per local brick. This thread keeps waking up every minute to check if there are any files to be healed based on the indices kept in index directory. Whenever child_up event comes, then also this index healer thread wakes up and crawls the indices and triggers heal. When self-heal-daemon is disabled on this particular volume then the healer thread keeps waiting until it is enabled again to perform heals. Full healer threads: Ec xlator starts a full healer thread for the local subvolume provided by glusterd to perform full crawl on the directory hierarchy to perform heals. Once the crawl completes the thread exits if no more full heals are issued. Changed xl-op prefix GF_AFR_OP to GF_SHD_OP to make it more generic.

* ec: Removed SSE2 dependencyXavier Hernandez2014-09-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | This patch implements the Galois Field multiplications using pure C code without any assembler support. This makes the ec xlator portable to other architectures. In the future it will be possible to use an optimized implementation of the multiplications using architecture dependent facilities (it will be automatically detected and configured). To allow bricks with different machine word sizes to be able to work seamlessly in the same volume, the minimum fragment length to be stored in any brick has been fixed to 512 bytes. Otherwise, different implementations will corrupt the data (SSE2 used 128 bytes, while new implementation would have used 64). This patch also removes the '-msse2' option added on patch http://review.gluster.org/8395/ Change-Id: Iaf6e4ef3dcfda6c68f48f16ca46fc4fb61a215f4 BUG: 1125166 Signed-off-by: Xavier Hernandez <xhernandez@datalab.es> Reviewed-on: http://review.gluster.org/8413 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Dan Lambright <dlambrig@redhat.com>
* ec: Add -msse2 option to avoid fedora/rawhide compilation errorsXavier Hernandez2014-07-311-1/+1
| | | | | | | | | | | | | | | | | This solves a compilation error on some compiler versions. To avoid compilation issues on non-Intel architectures, patch http://review.gluster.org/8366/ has already been merged. It disables ec on those architectures. These modifications are temporary patches until a proper solution for bug #1125166 is ready.
