* afr: thin-arbiter read txn changesRavishankar N2018-09-055-19/+320
| | | | | | | | | | | | | | | | If both data bricks are up, read subvol will be based on read_subvols. If only one data brick is up: - First qeury the data-brick that is up. If it blames the other brick, allow the reads. - If if doesn't, query the TA to obtain the source of truth. TODO: See if in-memory state can be maintained for read txns (BZ 1624358). updates: bz#1579788 Change-Id: I61eec35592af3a1aaf9f90846d9a358b2e4b2fcc Signed-off-by: Ravishankar N <ravishankar@redhat.com>
* New flag to glusterfsd binary to print libexec dirAravinda VK2018-09-056-1/+23
| | | | | | | | | | | | New CLI option for `glusterfsd` binary to get the path of libexec directory. This helps glusterd2 to detect the installed path of `gsyncd` and other binaries. Usage: `glusterfsd --print-libexecdir` Updates: bz#1193929 Change-Id: I8c1a74afd9acec7ee7bd3deabed9d9f20fe3fb5f Signed-off-by: Aravinda VK <avishwan@redhat.com>
* cli : fix coverity issue in cli-cmd-parser.cSunny Kumar2018-09-051-13/+8
| | | | | | | | | | | | This patch fixes 1175017 and 1382401. This patch fixes resource leak by validating brick_count is valid or not. If brick_count is not valid we are coming out in "cli_cmd_bricks_parse" without allocating memory to "brick_str" which is eventually pointed by bricks.

* cluster/afr: Delegate name-heal when possiblePranith Kumar K2018-09-043-27/+197
| | | | | | | | | | | | | | | | | | | | | | | | | Problem: When name-self-heal is triggered on the mount, it blocks lookup until name-self-heal completes. But that can lead to hangs when lot of clients are accessing a directory which needs name heal and all of them trigger heals waiting for other clients to complete heal. Fix: When a name-heal is needed but quorum number of names have the file and pending xattrs exist on the parent, then better to delegate the heal to SHD which will be completed as part of entry-heal of the parent directory. We could also do the same for quorum-number of names not present but we don't have any known use-case where this is a frequent occurrence so not changing that part at the moment. When there is a gfid mismatch or missing gfid it is important to complete the heal so that next rename doesn't assume everything is fine and perform a rename etc fixes bz#1622821 Change-Id: I8b002c85dffc6eb6f2833e742684a233daefeb2c Signed-off-by: Pranith Kumar K <pkarampu@redhat.com>

* libgfchangelog: Fix changelog history APIKotresh HR2018-08-314-5/+325
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: If requested start time and end time doesn't fall into first HTIME file, then history API fails even though continuous changelogs are avaiable for the requested range in other HTIME files. This is induced by changelog disable and enable which creates fresh HTIME index file. Cause and Analysis: Each HTIME index file represents the availability of continuous changelogs. If changelog is disabled and enabled, a new HTIME index file is created represents non availability of continuous changelogs. So as long as the requested start and end falls into single HTIME index file and not across, history API should succeed. But History API checks for the changelogs only in first HTIME index file and errors out if not available. Fix: Check in all HTIME index files for availability of continuous changelogs for requested change. fixes: bz#1622549 Change-Id: I80eeceb5afbd1b89f86a9dc4c320e161907d3559 Signed-off-by: Kotresh HR <khiremat@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | If this option is "ON' and if there is a lock contention for a file from 2 clients/self-heal daemon, an up call will be sent to all the clients holding that locks. Clients can handle this notification and may release the locks at the right time asap. If this option is ON, we get "instant" lock contention notification on client side. In next version of thin arbiter, we need to implement lock contention notification handling and two domain locking to synchronize update/access of xattrs of thin arbiter replica id file. This option is an efficient way to find out lock contention. In this case it is also helping to implement two domain locking for replica id file.

Instead, use snprintf(). Ensure sprintf() results do not truncate. Also: - save the result of strlen() and re-use it when possible. - move from strlen to SLEN or sizeof() for const strings. - move ret from int32 to int. Compile-tested only!

| | | | | | | | | | | | | | 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.

Also, unrelated, implemented str_to_data() via strn_to_data().
