* build: export minimum symbols from xlators for correct resolutionKaleb S. KEITHLEY2015-09-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | We've been lucky that we haven't had any symbol collisions until now. Now we have a collision between the snapview-client's svc_lookup() and libntirpc's svc_lookup() with nfs-ganesha's FSAL_GLUSTER and libgfapi. As a short term solution all the snapview-client's FOP methods were changed to static scope. See http://review.gluster.org/11805. This works in snapview-client because all the FOP methods are defined in a single source file. This solution doesn't work for other xlators with FOP methods defined in multiple source files. To address this we link with libtool's '-export-symbols $symbol-file' (a wrapper around `ld --version-script ...` --- on linux anyway) and only export the minimum required symbols from the xlator sharedlib. N.B. the libtool man page says that the symbol file should be named foo.sym, thus the rename of *.exports to *.sym. While foo.exports worked, we will follow the documentation. Signed-off-by: Kaleb S.

* all: reduce "inline" usageJeff Darcy2015-09-011-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | There are three kinds of inline functions: plain inline, extern inline, and static inline. All three have been removed from .c files, except those in "contrib" which aren't our problem. Inlines in .h files, which are overwhelmingly "static inline" already, have generally been left alone. Over time we should be able to "lower" these into .c files, but that has to be done in a case-by-case fashion requiring more manual effort. This part was easy to do automatically without (as far as I can tell) any ill effect. In the process, several pieces of dead code were flagged by the compiler, and were removed.

* Avoid conflict between contrib/uuid and system uuidEmmanuel Dreyfus2015-04-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glusterfs relies on Linux uuid implementation, which API is incompatible with most other systems's uuid. As a result, libglusterfs has to embed contrib/uuid, which is the Linux implementation, on non Linux systems. This implementation is incompatible with systtem's built in, but the symbols have the same names. Usually this is not a problem because when we link with -lglusterfs, libc's symbols are trumped. However there is a problem when a program not linked with -lglusterfs will dlopen() glusterfs component. In such a case, libc's uuid implementation is already loaded in the calling program, and it will be used instead of libglusterfs's implementation, causing crashes. A possible workaround is to use pre-load libglusterfs in the calling program (using LD_PRELOAD on NetBSD for instance), but such a mechanism is not portable, nor is it flexible. A much better approach is to rename libglusterfs's uuid_* functions to gf_uuid_* to avoid any possible conflict. This is what this change attempts.

* glfs_fini: Clean up all the resources allocated in glfs_new.Poornima G2015-03-041-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Initially even after calling glfs_fini(), all the threads created during init and many other resources like memory pool, iobuf pool, event pool and other memory allocs were not being freed. With this patch these resources are freed in glfs_fini(). The two thumb rules followed in this patch are: - The threads are not killed, they are made to exit voluntarily, once the queued tasks are completed. The main thread waits for the other threads to exit. - Free the memory pools and destroy the graphs only after all the other threads are stopped, so that there are less chances of hitting access after free. Resources freed and its order: 1. Destroy the inode table of all the graphs - Call forget on all the inodes. This will not be required when the cleanup during graph switch is implemented to perform inode table destroy. 2. Deactivate the current graph, call fini of all the xlators. 3. Syncenv destroy - Join the synctask threads and cleanup syncenv resources Sets the destroy mode, complete the existing synctasks, then join the synctask threads. After entering the destroy mode, -if a new synctask is submitted, it fails. -if syncenv_new() is called, it will end up creating new threads, but this is called only during init. 4. Poller thread destroy Register an event handler which sets the destroy mode for the poller. Once the poller is done processing all the events, it exits. 5. Tear down the logging framework The log file is closed and the log level is set to none, after this point no log messages appear either in log file or in stderr. 6. Destroy the timer thread Set the destroy bit, once the pending timer events are processed the timer thread exits. Note: Log infrastructure should be shutdown before destroying the timer thread as gf_log uses timers. 7. Destroy the glusterfs_ctx_t For all the graphs(active and passive), free graph, xlator structs and few other lists. Free the memory pools - iobuf pool, event pool, dict, logbuf pool, stub mem pool, stack mem pool, frame mem pool. Few things not addressed in this patch: 1. rpc_transport object not destroyed, the PARENT_DOWN should have destroyed this object but has not, needs to be addressed as a part of different patch 2. Each xlator fini should clean up the local pool allocated by its xlator. Needs to be addresses as a part of different patch. 3. Each xlator should implement forget to free its inode_ctx. Needs to be addresses as a part of different patch. 3.

Zerofill writes zeroes to a file in the specified range. This fop will be useful when a whole file needs to be initialized with zero (could be useful for zero filled VM disk image provisioning or during scrubbing of VM disk images). Client/application can issue this FOP for zeroing out. Gluster server will zero out required range of bytes ie server offloaded zeroing. In the absence of this fop, client/application has to repetitively issue write (zero) fop to the server, which is very inefficient method because of the overheads involved in RPC calls and acknowledgements. WRITESAME is a SCSI T10 command that takes a block of data as input and writes the same data to other blocks and this write is handled completely within the storage and hence is known as offload . Linux ,now has support for SCSI WRITESAME command which is exposed to the user in the form of BLKZEROOUT ioctl. BD Xlator can exploit BLKZEROOUT ioctl to implement this fop. Thus zeroing out operations can be completely offloaded to the storage device , making it highly efficient. The fop takes two arguments offset and size. It zeroes out 'size' number of bytes in an opened file starting from 'offset' position. This patch adds zerofill support to the following areas: - libglusterfs - io-stats - performance/md-cache,open-behind - quota - cluster/afr,dht,stripe - rpc/xdr - protocol/client,server - io-threads - marker - storage/posix - libgfapi Client applications can exloit this fop by using glfs_zerofill introduced in libgfapi.FUSE support to this fop has not been added as there is no system call for this fop. Changes from previous version 3: * Removed redundant memory failure log messages Changes from previous version 2: * Rebased and fixed build error Changes from previous version 1: * Rebased for latest master TODO : * Add zerofill support to trace xlator * Expose zerofill capability as part of gluster volume info Here is a performance comparison of server offloaded zeofill vs zeroing out using repeated writes.

As we can see there is a performance improvement of around 20% with this fop.

* build: remove useless explicit -fPIC -shared fromJeff Darcy2012-10-031-2/+2
| | | | | | | | | | | | | | | | | | | | CFLAGS libtool will automatically add "-fPIC" to the compiler command line as needed, so there is no need to specify it separately. "-shared" is normally a linker flag and has an odd effect when used with libtool --mode=compile, namely that it inhibits production of static objects. For that however, using AC_DISABLE_STATIC is a lot simpler.

| | | | | | | | | | | | | | | | | | | | | | fopen-keep-cache disables unconditional page-cache invalidations on file open in fuse (via FOPEN_KEEP_CACHE) and replaces that behavior with detection of remote changes and explicit invalidations from mount/fuse. This option improves local caching through the page cache and native client. This change defines a new 'invalidate' translator callback to identify when an inode's cache mapping has been determined to be invalid. md-cache implements the policy to detect and invoke inode invalidations. fuse-bridge and io-cache implement invalidate handlers to invalidate the respective caches (page cache in the case of fuse).

* localtime and ctime are not MT-SAFEKaleb S. KEITHLEY2012-06-291-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a number of nit-level issues throughout the source with the use of localtime and ctime. While they apparently aren't causing too many problems, apart from the one in bz 828058, they ought to be fixed. Among the "real" problems that are fixed in this patch: 1) general localtime and ctime not MT-SAFE. There's a non-zero chance that another thread calling localtime (or ctime) will over-write the static data about to be used in another thread 2) localtime(& <64-bit-type>) or ctime(& <64-bit-type>) generally not a problem on 64-bit or little-endian 32-bit. But even though we probably have zero users on big-ending 32-bit platforms, it's still incorrect. 3) multiple nested calls passed as params. Last one wins, i.e. over- writes result of prior calls. 4) Inconsistent error handling. Most of these calls are for logging, tracing, or dumping. I submit that if an error somehow occurs in the call to localtime or ctime, the log/trace/dump still should still occur. 5) Appliances should all have their clocks set to UTC, and all log entries, traces, and dumps should use GMT. 6) fix strtok(), change to strtok_r() Other things this patch fixes/changes (that aren't bugs per se): 1) Change "%Y-%m-%d %H:%M:%S" and similar to their equivalent shorthand, e.g. "%F %T" 2) change sizeof(timestr) to sizeof timestr. sizeof is an operator, not a function. You don't use i +(32), why use sizeof(<var>). (And yes, you do use parens with sizeof(<type>).) 3) change 'char timestr[256]' to 'char timestr[32]' where appropriate. Per-thread stack is limited. Time strings are never longer than ~20 characters, so why waste 220+ bytes on the stack? Things this patch doesn't fix: 1) hodgepodge of %Y-%m-%d %H:%M:%S versus %Y/%m/%d-%H%M%S and other variations. It's not clear to me whether this ever matters, not to mention 3rd party log filtering tools may already rely on a particular format. Still it would be nice to have a single manifest constant and have every call to localtime/strftime consistently use the same format.

* core: utilize mempool for frame->local allocationsAmar Tumballi2012-02-213-20/+22

It would be good to utilize the mem pool framework for xlator's local structures, so there is no allocation overhead.
