* core/various: python3 compat, prepare for python2 -> python3Kaleb S. KEITHLEY2018-05-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | see https://review.gluster.org/#/c/19788/ and https://review.gluster.org/#/c/19871/ Selected small fixes from 2to3 utility. Specifically apply, basestring, funcattrs, idioms, numliterals, set_literal, types, urllib, zip Note: these 2to3 fixes report no changes are necessary: exec, execfile, exitfunc, filter, getcwdu, intern, itertools, metaclass, methodattrs, ne, next, nonzero, operator, paren, raw_input, reduce, reload, renames, repr, standarderror, sys_exc, throw, tuple_params, xreadlines. Any 2to3 fixes not in the above two lists have more extensive changes which will follow in separate patches. most unicode changes suggested by 2to3 will need to be applied at the same time as changing the shebangs from python2 to python3. Prashanth notes that unicode strings in py2 need 'u' prefix; unicode strings in py3 3.0, 3.1, and 3.2 a 'u' prefix will throw an error, but in py3 3.3+ it is legal (or just ignored). All Linux dists we care about have 3.3 or later so we can leave 'u' prefixes on unicode strings. Change-Id: I49bba2f328b0ee24b9a8115a7183be979981563e updates: #411 Signed-off-by: Kaleb S.

* libgfapi: Fix lookup on rootKotresh HR2018-05-281-2/+2
| | | | | | | | | | | | | | | | | | | Lookup on root was sending "/" as the path. This will break the basename calculation in loc_copy and hence lookup on root was failing if the loc_copy was involved in the stack. With ctime, a first lookup on root initiates a metadata self heal because of ctime xattr not being same on all afr subvolumes. This results in loc_copy and hence the failure of lookup. Fix would be to send path with "." for the root. fixes: bz#1582516 Change-Id: Iafe4b99f249a4f5034ad34c1d30590de0e35aa0d Signed-off-by: Kotresh HR <khiremat@redhat.com>

* gfapi: various broken symbol versionsKaleb S. KEITHLEY2018-05-106-80/+107
| | | | | | | | | | | | | | | | | | | | | | lots of breakage in symbol versions: symbols added in 4.1 incorrectly, and symbols added in 4.1 but labeled 4.0.0, and symbols added in 3.13 incorrectly Not noticed until someone tried to build 3.13.2 on FreeBSD 11.1, despite the fact that we build on FreeBSD 10.3 IIRC, somehow the 3.13 errors aren't a build error there. Note: in rereading the Ulrich Drepper write-up I noticed that when a symbol version is changed, you are supposed to leave the old symbol in its original section in addition to adding it to its new section. Adding back those symbols to their original sections. Reported-by: Roman Serbski <mefystofel@gmail.com> Change-Id: I9a883546d08e0847f7228d8ea5943bc54275b319 fixes: bz#1575716 Signed-off-by: Kaleb S.

* gfapi: acutally avoid recall callback when closedv4.2devThomas Hindoe Paaboel Andersen2018-05-061-1/+2
| | | | | | | | | | | | Due to missing curly braces we end up calling the callback function even when state is GLFD_CLOSE. This patch adds the curly braces so both the log and actual callback is skipped.

* gfapi : RECALL_LEASE implementationSoumya Koduri2018-05-048-28/+532
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Right now there are two types of upcalls * poll method * registering callback But callback can be registered per fs and same callback fn shall be used for any lease recall with object handle as argument as done for cache invalidation. TODO: RECALL LEASE for each glfd (for future reference) (may be needed fo Samba as they do not deal with object handles. In case of RECALL_LEASE, we could associate separate cbk function for each glfd either by - extending pub_glfs_lease to accept new args (recall_cbk_fn, cookie) - or by defining new API "glfs_register_recall_cbk_fn (glfd, recall_cbk_fn, cookie) . In such cases, flag it and instead of calling below upcall functions, define a new one to go through the glfd list and invoke each of theirs recall_cbk_fn. Plus added following as well * passed lease id to dict in required arguments * added flag check in pub_glfs_open Updates: #350 Change-Id: I07a971f0f26ec6aae0b9f9a5613504317dee153b Signed-off-by: Soumya Koduri <skoduri@redhat.com> Signed-off-by: Poornima G <pgurusid@redhat.com> Signed-off-by: Jiffin Tony Thottan <jthottan@redhat.com>

This patch does two things: 1) minor cleanup of configure(.ac) to explicitly use python2 2) change all the shebang lines to #!/usr/bin/python2 and add them where they were missing based on warnings emitted during rpmbuild. In a follow-up patch python2 will eventually be changed to python3. Before that python2-isms (e.g. print, string.join(), etc.) need to be converted to python3. Some of those can be rewritten in version agnostic python. E.g. print statements become print() with "from __future_ import print_function". The python 2to3 utility will be used for some of those. Also Aravinda has given guidance in the comments to the first patch for changes. updates: #411 Change-Id: I471730962b2526022115a1fc33629fb078b74338 Signed-off-by: Kaleb S.

Outside of libgfapi, nothing now uses/needs this old typedef, move it into the C file that needs it. Similarly glfs_realpath34() decl should not be in glfs.h. Period. Old applications were compiled with the then glfs_realpath() decl and linked with glfs_realpath@@GFAPI_3_4.0. New applications should only call glfs_realpath() and it will be linked to the new/current glfs_realpath().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The include path in glusterfs-api.pc looks like -I${includedir}/glusterfs However, client code will include the glusterfs headers using #include <glusterfs/api/glfs.h> rather than #include <api/glfs.h> which makes the "/glusterfs" part entirely unnecessary. More importantly, on some platforms such as FreeBSD, the header files for glusterfs will be installed in /usr/local/include, which is *not* part of the compiler's default include path, so compilation will fail with something like fatal error: 'glusterfs/api/glfs.h' file not found #include <glusterfs/api/glfs.h> ^~~~~~~~~~~~~~~~~~~~~~ The fix is to simply drop the extra "/glusterfs". The same change is applied to other *.pc files as well, althought I haven't actually tested those. A test program (gfapi-load-volfile) and the glfsxmp example application were using the wrong include paths, so they had to be fixed as well.

This can be made use by the process like aux mount done by quota, geo-rep, etc by adding another option in the aux mount " -o process-name=gsync_mount" Updates: #178 Signed-off-by: hari gowtham <hgowtham@redhat.com> Change-Id: Ie4d02257216839338043737691753bab9a974d5e Reviewed-on: https://review.gluster.org/17957 Smoke: Gluster Build System <jenkins@build.gluster.org> Tested-by: hari gowtham <hari.gowtham005@gmail.com> Reviewed-by: Amar Tumballi <amarts@redhat.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Atin Mukherjee <amukherj@redhat.com> Reviewed-by: Aravinda VK <avishwan@redhat.com> Reviewed-by: Niels de Vos <ndevos@redhat.com>

| | | | | | | | | | | | | | | | | | | | | Issue: The caller of glfs_setxattr sends a buffer to set as the value. We create a dict in which the pointer to the value is set. Underlying layers like md-cache take a ref on this dict to store the value for a longer time. But the moment setxattr is complete, the caller of glfs_setxattr can free the value memory. Solution: memcpy the setxattr value to the gluster buffer.

* gfapi: mark glfs_ipc() for internal use onlyNiels de Vos2017-07-265-20/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | The 3.7 version of glfs_ipc() has never been used by external applications. There is little use for internal xlator communication that is triggered from outside of core GlusterFS executables. This function has now been removed from libgfapi.so. For Gluster 4.0 a new variation for glfs_ipc() has been added. The function expects dict_t parameters, which are currently not available for external applications. There is no sense in providing glfs_ipc() for non-core GlusterFS executables. Therefore, glfs_ipc() has been marked as private, and the declaration is now in the glfs-internal.h header. The Python test case (tests/features/ipctest.py) is not correct and will be re-written in C to prevent portability issues. This test is currently disabled (commit d26f0bac149d495fa93710c3f7b6b63c36cb8387).

* mem-pool: initialize pthread_key_t pool_key in mem_pool_init_early()Niels de Vos2017-07-191-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is not possible to call pthread_key_delete for the pool_key that is intialized in the constructor for the memory pools. This makes it difficult to do a full cleanup of all the resources in mem_pools_fini(). For this, the initialization of pool_key should be moved to mem_pool_init(). However, the glusterfsd binary has a rather complex initialization procedure. The memory pools need to get initialized partially to get mem_get() functionality working. But, the pool_sweeper thread can get killed in case it is started before glusterfsd deamonizes. In order to solve this, mem_pools_init() is split into two pieces: 1. mem_pools_init_early() for initializing the basic structures 2. mem_pools_init_late() to start the pool_sweeper thread With the split of mem_pools_init(), and placing the pthread_key_create() in mem_pools_init_early(), it is now possible to correctly cleanup the pool_key with pthread_key_delete() in mem_pools_fini(). It seems that there was no memory pool initialization in the CLI. This has been added as well now. Without it, the CLI will not be able to call mem_get() successfully which results in a hang of the process.

* gfapi: prevent mem-pool leak in case glfs_new_fs() failsNiels de Vos2017-07-121-12/+21
| | | | | | | | | | | | | | | | | | | | | | | | Commit 7039243e187 adds a call to mem_pools_init() so that the memory pool cleanup thread ("sweeper") is started. However, now it is possible that users of gfapi can not cleanup this thread because glfs_new() can return NULL, but the sweeper is still running. In case glfs_fs_new() fails, mem_pools_fini() needs to be called as well. This seems more correct than calling mem_pools_init() after glfs_fs_new(), and this makes using memory pools possible *really* early in the gfapi initialization.

* mgtm/core : use sha hash function for volfile checkMohammed Rafi KC2017-07-101-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We are storing the entire volfile and using this to check volfile change. With brick multiplexing there will be lot of graphs per process which will increase the memory foot print of the process. So instead of storing the entire graph we could use sha256 and we can compare the hash to see whether volfile change happened or not. Also with Brick multiplexing, the direct comparison of vol file is not correct. There are two problems. Problem 1: We are currently storing one single graph (the last updated volfile) whereas, what we need is the entire graph with all atttached bricks. If we fix this issue, we have second problem Problem 2: With multiplexing we have a graph that contains multiple bricks. But what we are checking as part of the reconfigure is, comparing the entire graph with one single graph, which will always fail. Solution: We create list in glusterfs_ctx_t that stores sha256 hash of individual brick graphs. When a graph changes happens we compare the stored hash and the current hash. If the hash matches, then no need for reconfigure. Otherwise we first do the reconfigure and then update the hash. For now, gfapi has not changed this way. Meaning when gfapi volfile fetch or reconfigure happens, we still store the entire graph and compare, each memory. This is fine, because libgfapi will not load brick graphs. But changing the libgfapi will make the code similar in both glusterfsd-mgmt and api. Also it helps to reduce some memory.

| | | | | | | | | | | | | | | | | | | | | | | | These are both needed because GFAPI clients are a bit unique. They can be long-running, so they can potentially benefit from the memory reclamation that mem_pools_init will enable. On the other hand, they might completely tear down their Gluster environment well before the process exits, so they need mem_pools_fini as well. Our main and auxiliary daemons do need mem_pools_init but don't need to call it themselves because that's handled for them in glusterfsd.c right after they daemonize. They don't need mem_pools_fini, because the only place they could *safely* call it is right before exit and then it won't do them any good. Transient processes (e.g. gf_attach) don't benefit from either because, well, they're transient. They'll be gone before memory reclamation matters.
