2018-10-18T13:26:29+00:00

This patch fixes below issues in gfapi lease code-path
* 'glfs_setfsleasid' should allow NULL input to be
   able to reset leaseid
* Applications should be allowed to (un)register for
  upcall notifications of type GLFS_EVENT_LEASE_RECALL
* APIs added to read contents of GLFS_EVENT_LEASE_RECALL
  argument which is of type "struct glfs_upcall_lease"

api: fill out attribute information if not valid

2018-10-17T23:36:13+00:00

translators like readdir-ahead selectively retain entry information of
iatt (gfid and type) when rest of the iatt is invalidated (for write
invalidating ia_size, (m)(c)times etc). Fuse-bridge uses this
information and sends only entry information in readdirplus
response. However such option doesn't exist in gfapi. This patch
modifies gfapi to populate the stat by forcing an extra lookup.

Thanks to Shyamsundar Ranganathan  and Prashanth
Pai  for tests.

gfapi: revert several patchs that introduced pre/post attrs

2018-09-17T14:26:06+00:00

Reverted the following:
  - 248152767b0599986bbb6bb35fc27197f6be6964
  - 09943beb499617212f2985ca8ea9ecd1ed1b470e
  - d01f7244e9d9f7e3ef84e0ba7b48ef1b1b09d809

The reverts are redone by hand, due to clang format changes
that made using git to revert the changes more tedious.

gfapi: revert "gfapi: return pre/post attributes at callback for glfs api"

2018-09-17T14:26:06+00:00

This reverts commit 384562b294e9a7847403961e878a4daa0fff33eb.

The revert is done manually owing to the clang format changes,
and the 4.1 patch that reverts this fix is used as the source
for the revert.

The 4.1 patch has the commit ID: 98376e0c0a

shebangs changed from /usr/bin/python2 to /usr/bin/python3.
(Reminder, various distribution packaging guidelines require use
of explicit python version and don't allow '#!/usr/bin/env python',
regardless of how handy that idiom may be.)

glusterfs.spec(.in) package python{2,3}-gluster and python2 or
python3 dependencies as appropriate.

configure(.ac):
+ test for and use python2 or python3 as appropriate. If build
  machine has python2 and python3, use python3. Override by
  setting PYTHON=/usr/bin/python2 when running configure.
+ PYTHONDEV_CPPFLAGS from python[23]-config --includes is a
  better match to the original python sysconfig.get_python_inc().
  All those other extraneous flags breaks the build.
+ Only change the shebangs once. Changing them over and over
  again, e.g., during a `make glusterrpms` in extras/LinuxRPM
  just sends make (is it really make that's looping?) into an
  infinite loop. If you figure out why, let me know.
+ Oldest python2 is python2.6 on CentOS 6 and Debian 8 (Jessie).
  Everything else has 2.7 or 3.x
+ logic from https://review.gluster.org/c/glusterfs/+/21050, which
  needs to be removed/merged after that patch is merged.

Builds on CentOS 6, CentOS 7, Fedora 28, Fedora rawhide, and the
mysterious RHEL > 7.

build: add --enable-asan configure options

2018-08-30T05:41:26+00:00

Introduce a `./configure --enable-asan` to build with
`-fsanitize=address -fno-omit-frame-pointer` options. This uses the
libasan.so shared library, so that needs to be available.

While running builds with the ASAN options, several linker issues
surfaced and these have been addressed with this change as well.
Building with --enable-asan has been tested on Fedora 28.

glfs-fops.c, glfs.c: strncpy() -> sprintf(), reduce strlen()'s

2018-08-24T16:26:36+00:00

strncpy may not be very efficient for short strings copied into
a large buffer: If the length of src is less than n,
strncpy() writes additional null bytes to dest to ensure
that a total of n bytes are written.

Instead, use snprintf().

Also, save the result of strlen() and re-use it when possible.

Compile-tested only!
