glusterfs.git/api/examples, branch release-3.8-fb gfapi: build a *working* glfsxmp to show how it's done 2017-09-08T04:42:17+00:00 Jeff Darcy jdarcy@fb.com 2017-07-05T12:31:14+00:00 92ccb288e388fb7fbdb9944999ad20ff7e2f13c3 Summary: Previously, glfsxmp would fail way down in XDR code. The reasons are still a bit unclear, but exactly duplicating the build flags etc. we use for other programs seems to fix the issue. With this change, we have one example of one set of flags that can be used to build other GFAPI programs.

libgfapi: adding 'follow' flag to glfs_h_lookupat() 2015-08-24T16:21:51+00:00 Jiffin Tony Thottan jthottan@redhat.com 2015-08-11T10:30:47+00:00 1ead86a8bcbfe4045729466e4b98f765f3c13c8d Previously glfs_h_lookupat won't follow the symlink, this patch introduces new flag `follow` which will resolve the same.

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]
