* debug/sink: add xlator to aid in resource leak debuggingNiels de Vos2017-04-252-0/+177
| | | | | | | | | | | | | | | | | | | | | | This new xlator does not allocate any resources on init(). This makes it a good option to use for debugging xlator releated resources leaks on fini(). By putting the sink xlator as single xlator in a .vol file, and loading it through gfapi, we can investigate the resource leaks that are happening through gfapi (and the Gluster core). By extending the .vol file with additional xlators, it is possible to analyze resource leaks of single xlators.

* libgfapi: adding 'follow' flag to glfs_h_lookupat()Jiffin Tony Thottan2015-08-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously glfs_h_lookupat won't follow the symlink, this patch introduces new flag `follow` which will resolve the same. Applications linking against the new library will need to use the new glfs_h_lookupat API call. In order to stay compatible with existing binaries that use the previous glfs_h_lookupat() function, the old symbol needs to stay available. Verification that there are two versions of glfs_h_lookupat: $ objdump -T /usr/lib64/libgfapi.so.0 | grep -w glfs_h_lookupat 0000000000015070 g DF .text 000000000000021e GFAPI_3.7.4 glfs_h_lookupat 0000000000015290 g DF .text 0000000000000008 (GFAPI_3.4.2) glfs_h_lookupat Testing with a binary (based on anonymous_fd_read_write.c from ./tests/) that was linked against the old library: $ objdump -T ./lookupat | grep -w glfs_h_lookupat 0000000000000000 DF *UND* 0000000000000000 GFAPI_3.4.2 glfs_h_lookupat Enable debugging for 'ld.so' so that we can check that the GFAPI_3.4.2 version of the symbol gets loaded: $ export LD_DEBUG_OUTPUT=lookupat.ld.log LD_DEBUG=all $ ./lookupat $ grep -w glfs_h_lookupat lookupat.ld.log.2543 2543: symbol=glfs_h_lookupat; lookup in file=./lookupat [0] 2543: symbol=glfs_h_lookupat; lookup in file=/lib64/libgfapi.so.0 [0] 2543: binding file ./lookupat [0] to /lib64/libgfapi.so.0 [0]: normal symbol `glfs_h_lookupat' [GFAPI_3.4.2] Change-Id: I8bf9b1c19a0585f681bc1a7f84aad1ccd0f75f6a BUG: 1252410 Signed-off-by: Jiffin Tony Thottan <jthottan@redhat.com> Signed-off-by: Niels de Vos <ndevos@redhat.com> Reviewed-on: http://review.gluster.org/11883 Reviewed-by: soumya k <skoduri@redhat.com> Reviewed-by: Kaleb KEITHLEY <kkeithle@redhat.com> Tested-by: NetBSD Build System <jenkins@build.gluster.org>
* glusterd: initialize the daemon services on demandAtin Mukherjee2015-07-271-3/+6
| | | | | | | | | | | | | | | | | | | | | | As of now all the daemon services are initialized at glusterD init path. Since socket file path of per node daemon demands the uuid of the node, MY_UUID macro is invoked as part of the initialization. The above flow breaks the usecases where a gluster image is built following a template could be Dockerfile, Vagrantfile or any kind of virtualization environment. This means bringing instances of this image would have same UUIDs for the node resulting in peer probe failure. Solution is to lazily initialize the services on demand.
