* gfapi: fix issue when glfs_set_logging is called concurrentlyZhang Huan2017-12-061-5/+0
| | | | | | | | | | | | glfs_set_logging changes THIS->ctx without lock, during initialization THIS refers to global_xlator. Concurrently changing it could result in global_xlator.ctx being some fs->ctx. After that fs->ctx is destroyed, global_xlator.ctx refers to an invalid pointer and that causes crash in sbusequent access.

* *.pc: Fix include path in CflagsAndrea Bolognani2017-11-081-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* gfapi: Duplicate the buffer sent in setxattr callsPoornima G2017-08-073-6/+21
| | | | | | | | | | | | | | | | | | | | | 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.

* 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.

* gfapi: add mem_pools_init and mem_pools_fini callsKaleb S. KEITHLEY2017-07-051-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | The most common pattern, both in our code and elsewhere, is this: struct _xyz { ... }; typedef struct _xyz xyz_t; These exceptions - especially call_frame/call_stack - have been slowing down code navigation for years. By converging on a single pattern, navigating from xyz_t in code to the actual definition of struct _xyz (i.e. without having to visit the typedef first) might even be automatable.

But often applications may need extra information, like for eg., NFS-Ganesha which operates on handles needs handles for each of those dirents returned. So this would require extra calls to the backend, in this case LOOKUP (which is very expensive operation) resulting in very low readdir performance. To address that introducing this new API using which applications can make request for any extra information to be returned as part of readdirplus response. Currently this new api returns stat and handles as demanded by application. The synopsis of the API is noted in glfs.h. @todo: * Enhance test script using this new API Below were the perf results on single brick volume with and without these changes - Dataset used - 10*100 directories and each directory containing 100 empty files.

| | | | | | | | | | | | | | | | | | | | | | | This patch adds support for multiple brick translator stacks running in a single brick server process. This reduces our per-brick memory usage by approximately 3x, and our appetite for TCP ports even more. It also creates potential to avoid process/thread thrashing, and to improve QoS by scheduling more carefully across the bricks, but realizing that potential will require further work. Multiplexing is controlled by the "cluster.brick-multiplex" global option. By default it's off, and bricks are started in separate processes as before. If multiplexing is enabled, then *compatible* bricks (mostly those with the same transport options) will be started in the same process.

In general any call-back function executed in epoll thread should not call any blocking call which waits on a network reply either directly or indirectly, e.g. syncop functions should not be called in these threads. As a fix we should not wait for migration in the call-back path.

* gfapi: async fops should unref in callbacksRaghavendra Talur2016-11-051-18/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If fd is unref'd at the end of async call then the unref in cbks would lead to double unref and possible crash. Removing duplicate unrefs. Added unref only in failure cases. A simple test case has been added to test async write case. Need to extend the same for other async APIs too. Details: All glfd based calls in libgfapi, except for glfs_open and glfs_close, behave in the same way. At the start of the operation, they take a ref on glfd and fd. At the end of the operation, they unref it. Async calls are a little different as they unref in the cbk function. A successfull open call does not unref either the glfd or fd, thereby functioning as a reference for a OPEN file object. glfs_close makes a syncop_flush call sandwiched between a fd ref and unref(this can be removed, more on this below), followed by a call to glfs_mark_glfd_for_deletion which unrefs glfd and also calls glfs_fd_destroy as a release function thereby doing a unref on fd too. Functionally, there is no problem with how everything works when as described above. However, it is a little non-intuitive that we need to perform a fd_unref as a consequence of a implicit fd_ref that happens within glfs_resolve_fd. As we perform a GF_REF_GET(glfd) at the start of every operation, it would be worthwhile to remove the fd_ref that glfs_resovle_fd takes and do away with explicit fd_unref()s at the end of every operation. This is the same reason why we don't need the fd_ref in glfs_close. This is however not in the scope of this patch.
