* core: Resolve dict_leak at the time of destroying graphMohit Agrawal2019-01-141-2/+2
| | | | | | | | | | | | Problem: In gluster code some of the places it call's get_new_dict to create a dictionary without taking reference so at the time of dict_unref it has become a leak Solution: To resolve the same call dict_new instead of get_new_dict updates bz#1650403 Change-Id: I3ccbbf5af07079a4fa09aad2cd0458c8625b2f06 Signed-off-by: Mohit Agrawal <moagrawal@redhat.com>
* libglusterfs: Move devel headers under glusterfs directoryShyamsundarR2018-12-051-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | libglusterfs devel package headers are referenced in code using include semantics for a program, this while it works can be better especially when dealing with out of tree xlator builds or in general out of tree devel package usage. Towards this, the following changes are done, - moved all devel headers under a glusterfs directory - Included these headers using system header notation <> in all code outside of libglusterfs - Included these headers using own program notation "" within libglusterfs This change although big, is just moving around the headers and making it correct when including these headers from other sources. This helps us correctly include libglusterfs includes without namespace conflicts.

* build: rename event.h to gf-event.hNiels de Vos2018-07-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Newer FreeBSD versions (noticed with 10.3-RELEASE) provide a event.h file that on occasion gets included instead of the libglusterfs file. When this happens, 'struct event_pool' will not be defined and building will fail with errors like: autoscale-threads.c:18:55: error: incomplete definition of type 'struct event_pool' int thread_count = pool->eventthreadcount; ~~~~^ autoscale-threads.c:17:16: note: forward declaration of 'struct event_pool' struct event_pool *pool = ctx->event_pool; ^ This problem is caused by 'pkg-config --cflags uuid' that adds /usr/local/include to the GF_CPPFLAGS. The use of libuuid is preferred so that the contrib/uuid/ directory can be removed. By renaming event.h to gf-event.h there is no conflict between the different event.h files anymore and compiling on FreeBSD works without issues.

* gfapi: mark glfs_ipc() for internal use onlyNiels de Vos2017-07-261-10/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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

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.

This can lead to dead lock if we consume all the epoll threads. 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The glfs_callback_arg and glfs_callback_inode_arg were allocated by gfapi, and expected to be free()'d by the application. However it is not reasonable to expect that applications use the same memory allocator to as the compiled libgfapi.so. For instance, it is possible that gfapi uses glibc malloc/free, and an application like NFS-Ganesha the versions from jemalloc. Mismatching of the malloc() and free() functions causes segmentation faults at best. In order to prevent problems like this in the future, the API for applications that consume upcalls has been remodeled. Any of the structures that gfapi allocates, should be free'd with glfs_free(). The members of the structures can not be accessed directly anymore, each has its own function to access now. Correcting the naming of the functions, structures and constants is a continuation of commit 2775dc64101ed37c8d9809bf9852dbf0746ee2b6. These new improvements not only have correct prefixes for the functions and structures, the naming also reflects more to the upcall framework and does not use "callback" anymore.

* api: use versioned symbols for minor ABI changeKaleb S KEITHLEY2016-06-141-6/+6
| | | | | | | | | | | | | | | | | | | | | | | No need to expand the API/ABI. E.g., see how glfs_lookupat changed between 3.7.0 and 3.7.4 IIRC (I originally argued against versioning the library. I wanted to just add new functions as they were needed, as was initially done for glfs_ipc and glfs_ipc_xd in the master branch for 4.0. But others strongly wanted versioning.) Having made the decision to use versioning, I believe we should continue. At least until we have a public decision that we're no longer going to use versioning.

* libglusterfs (timer): race conditions, illegal mem access, mem leakKaleb S KEITHLEY2016-06-011-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | While investigating gfapi memory consumption with valgrind, valgrind reported several memory access issues. Also see the timer 'registry' being recreated (shortly) after being freed during teardown due to the way it's currently written. Passing ctx as data to gf_timer_proc() is prone to memory access issues if ctx is freed before gf_timer_proc() terminates. (And in fact this does happen, at least in valgrind.) gf_timer_proc() doesn't need ctx for anything, it only needs ctx->timer, so just pass that. Nothing ever calls gf_timer_registry_init(). Nothing outside of timer.c that is. Making it and gf_timer_proc() static.

| | | | | | | | | | | | | | | | | | | | | | | | NSR needs logging that is different than our existing changelog in several ways: * Full data, not just metadata * Pre-op, not post-op * High performance * Supports the concept of time-bounded "terms" Others (for example EC) might need the same thing. This patch adds such a translator. It also adds code to dump the resulting journals, and to replay them using syncops, plus (very rudimentary) tests for all of the above.

* libgfapi: glfd close is not correctly handled for async fopRajesh Joseph2016-02-101-22/+28
| | | | | | | | | | | | | | | | | | | | | | | There is chance that before the async fop is complete client can send a close. libgfapi destroys glfd on close. Therefore it can lead to crash or unexpected behaviour when the pening fop reaches libgfapi layer. Currently we don't provide any api to cancel these outstanding fops neither we check if the glfd is already closed or not. Therefore as a fix provided refcount for glfd. Each fop (sync or async) will take a ref and once the fop is complete it will unref the refcount. We should not call the registered callback function if glfd is already closed. To achieve this we maintain state of glfd so that we can safely take a call if the fd is closed or not.
