* gfapi : making glfs_setattr/glfs_fsetattr as publicArjun2019-01-161-1/+1
| | | | | | | | | | Initially glfs_fsetattr and glfs_setattr, both functions accepted iatt as arguements but now they accept stat and later in the function the stat is being converted to iatt so that it can be passed to syncop_fsetattr/syncop_setattr.

* libglusterfs: Move devel headers under glusterfs directoryShyamsundarR2018-12-051-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | 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.

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

| | | | | | | | | | | | | | | | | | | | | 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/handleops: Introducing glfs_xreaddirplus_r() fop for handleopsSoumya Koduri2017-05-021-0/+45

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.

* gfapi: redesign the public interface for upcall consumersNiels de Vos2016-09-281-60/+166
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* gfapi: do not cache upcalls if the application is not interestedNiels de Vos2016-08-251-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the volume option 'features.cache-invalidation' is enabled, upcall events are sent from the brick process to the client. Even if the client is not interested in upcall events itself, md-cache or other xlators may benefit from them. By adding a new 'cache_upcalls' boolean in the 'struct glfs', we can enable the caching of upcalls when the application called glfs_h_poll_upcall(). NFS-Ganesha sets up a thread for handling upcalls in the initialization phase, and calls glfs_h_poll_upcall() before any NFS-client accesses the NFS-export. In the future there will be a more flexible registration API for enabling certain kind of upcall events. Until that is available, this should work just fine. Verificatio of this change is not trivial within our current regression test framework. The bug report contains a description on how to reliably reproduce the problem with the glusterfs-coreutils.

| | | | | | | | | | | | | | | | | | | | | | | | | In "glfs_h_poll_cache_invalidation", we need to send upcall only if there is a corresponding inode entry in the gfapi inode table for that handle. That's because the application will have reference to the inode as long as it operates on any handle. That means the only case in which we cannot find inode is when the application has closed the handle (either as part of unlink or for any other purpose). But since it will have no more references and will not be interested in any upcall event for that handle, we can safely ignore such cases. Note: This will affect only that particular applicaiton process/local libgfapi client.

* gfapi: Use inode_forget in case of handle objectsSoumya Koduri2016-02-231-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently with gfapi, even if applications release their reference on paritular inode entries, those entries never get destroyed as they shall always have positive nlookup count unless inode_table exceeds lru limit. Since inodes and their contexts can consume considerable amount of memory, applications may end up consuming lot of memory and may even get OOM killed. To avoid that, have considered below approaches (for handle based access)- a) Do 'inode_lookup' only if the corresponding inode is created for the first time and forget it during close of the handle This shall not work as multiple handle objects can refer to same inode entry and inode_forget from second handle object onwards shall result in assert. b) Do 'inode_lookup' during a handle or fd creation But this approach shall affect the performance of the fops which operate on neither handle nor fd. c) current approach taken- Applications using glfs handle objects hold a reference on corresponding inode entries. Hence it is safe to forget those inodes and make nlookup count to '0' while trying to delete those handle objects. That way the last unref (i.e, from the last handle close) shall result in inode_destroy().

* libgfapi: glfd close is not correctly handled for async fopRajesh Joseph2016-02-101-5/+10
| | | | | | | | | | | | | | | | | | | | | | | 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.
