* libglusterfs: add library wrapper for time()Dmitry Antipov2020-08-171-5/+5

* upcall: Avoid sending notifications for invalid inodesSoumya Koduri2019-06-141-1/+18
| | | | | | | | | | | | | | | | | | | For nameless LOOKUPs, server creates a new inode which shall remain invalid until the fop is successfully processed post which it is linked to the inode table. But incase if there is an already linked inode for that entry, it discards that newly created inode which results in upcall notification. This may result in client being bombarded with unnecessary upcalls affecting performance if the data set is huge. This issue can be avoided by looking up and storing the upcall context in the original linked inode (if exists), thus saving up on those extra callbacks.

* libglusterfs: Move devel headers under glusterfs directoryShyamsundarR2018-12-055-20/+20
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* md-cache: Do not invalidate cache post set/remove xattrPoornima G2018-07-111-9/+4
| | | | | | | | | | | | | | | Since setxattr and removexattr fops cbk do not carry poststat, the stat cache was being invalidated in setxatr/remoxattr cbk. Hence the further lookup wouldn't be served from cache. To prevent this invalidation, md-cache is modified to get the poststat in set/removexattr_cbk in dict. Co-authored with Xavi Hernandez.

* build: add --without-server optionNiels de Vos2018-02-191-0/+2
| | | | | | | | | | | | | | | | With Gluster 4.0 we will not provide the server components for EL6 and older. At one point Gluster 4.x will get GlusterD2, which requires Golang tools in the distribution. EL6 does not contain these at the moment. With this change, it is possible to `./configure --without-server` which prevents building glusterd and the xlators for the bricks. Building RPMs can pass `--without server` and the glusterfs-server sub-package will not be created.

* gfapi: Duplicate the buffer sent in setxattr callsPoornima G2017-08-071-2/+2
| | | | | | | | | | | | | | | | | | | | | 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.

* marker: Fix inode value in loc, in setxattr fopPoornima G2017-02-201-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | On recieving a rename fop, marker_rename() stores the, oldloc and newloc in its 'local' struct, once the rename is done, the xtime marker(last updated time) is set on the file, but sending a setxattr fop. When upcall receives the setxattr fop, the loc->inode is NULL and it crashes. The loc->inode can be NULL only in one valid case, i.e. in rename case where the inode of new loc can be NULL. Hence, marker should have filled the inode of the new_loc before issuing a setxattr. marker_rename_cbk was already fixed in a previous commit. Fixing marker_rename_done to send valid inode in this commit. Also in upcall check for NULL inode so that there is no crash.

* md-cache, afr: Reduce the window of stale readPoornima G2016-10-203-114/+283
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Consider a replica setup, where one mount writes data to a file and the other mount reads the file. In afr, read operations are not transaction based, a brick(read subvolume) is chosen as a part of lookup or other operations, read is always wound only to the read subvolume, even if there was write from a different client that failed on this brick. This stale read continues until there is a lookup or any write operation from the mount point. Currently, this is not a major issue, as a lookup is issued before every read and it will switch the read subvolume to a correct one. But with the plan of increasing md-cache timeout to 600s, the stale read problem will be more pronounced, i.e. stale read can continue for 600s(or more if cascaded with readdirp), as there will be no lookups. Solution: Afr doesn't have any built-in solution for stale read(without affecting the performance). The solution that came up, was to use upcall. When a file on any brick is marked bad for the first time, upcall sends a notification to all the clients that had recently accessed the file. The solution has 2 parts: - Identifying when a file is marked bad, on any of the bricks, for the first time - Client side actions on recieving the notifications Identifying when a file is marked bad on any of the bricks for the first time: ----------------------------------------------------------------------------- The idea is to track xattrop in upcall. xattrop currently comes with 2 afr xattrs - afr dirty bit and afr pending xattrs. Dirty xattr is set to 1 before every write, and is unset if write succeeds. In certain scenarios, dirty xattr can be 0 and still the file could be bad copy. Hence do not track dirty xattr. Pending xattr is set on the good copy, indicating the other bricks that have bad copy. It is still not as simple as, notifying when any of the pending xattrs change. It could lead to flood of notifcations, in case the other brick is completely down or consistantly failing. Hence it is important to notify only once, the first time a good copy is marked bad. Client side actions on recieving pending xattr change, notification: -------------------------------------------------------------------- md-cache will invalidate the cache of that file, so that further lookup is passed down to afr and hence update the read subvolume. Invalidating only in md-cache is not enough, consider the folling oder of opertaions: - pending xattr invalidation - invalidate md-cache - readdirp on the bad read subvolume - fill md-cache - lookup (served from md-cache) - read - wound to the old read subvol. Hence, along with invalidating md-cache, it is very important to reset the read subvolume for that file, in afr. Design Credit: Anuradha Talur, Ravishankar N 1. xattrop doesn't carry info saying post op/pre op. 2. Pre xattrop will have 0 value for all pending xattrs, the cbk of pre xattrop carries the on-disk xattr value. Non zero indicated healing is required. 3. Post xattrop will have non zero value for any of the pending xattrs, if the fop failed on any of the bricks.

Rewrite the make rules to do what xdrgen does. Now we can get rid of xdrgen. Note 1. netbsd6's sed doesn't do -i. Why are we still running smoke tests on netbsd6 and not netbsd7? We barely support netbsd7 as it is. Note 2. Why is/was libgfxdr.so (.../rpc/xdr/src/...) linked with libglusterfs? A cut-and-paste mistake? It has no references to symbols in libglusterfs. Note3. "/#ifndef\|#define\|#endif/" (note the '\'s) is a _basic_ regex that matches the same lines as the _extended_ regex "/#(ifndef|define|endif)/". To match the extended regex sed needs to be run with -r on Linux; with -E on *BSD. However NetBSD's and FreeBSD's sed helpfully also provide -r for compatibility. Using a basic regex avoids having to use a kludge in order to run sed with the correct option on OS X. Note 4. Not copying the bit of xdrgen that inserts copyright/license boilerplate. AFAIK it's silly to pretend that machine generated files like these can be copyrighted or need license boilerplate. The XDR source files have their own copyright and license; and their copyrights are bound to be more up to date than old boilerplate inserted by a script. From what I've seen of other Open Source projects -- e.g. gcc and its C parser files generated by yacc and lex -- IIRC they don't bother to add copyright/license boilerplate to their generated files. It appears that it's a long-standing feature of make (SysV, BSD, gnu) for out-of-tree builds to helpfully pretend that the source files it can find in the VPATH "exist" as if they are in the $cwd. rpcgen doesn't work well in this situation and generates files with "bad" #include directives. E.g. if you `rpcgen ../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.x`, you get an #include directive in the generated .c file like this: ... #include "../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.h" ... which (obviously) results in compile errors on out-of-tree build because the (generated) header file doesn't exist at that location. Compared to `rpcgen ./glusterfs3-xdr.x` where you get: ... #include "glusterfs3-xdr.h" ... Which is what we need. We have to resort to some Stupid Make Tricks like the addition of various .PHONY targets to work around the VPATH "help". Warning: When doing an in-tree build, -I$(top_builddir)/rpc/xdr/... looks exactly like -I$(top_srcdir)/rpc/xdr/... Don't be fooled though. And don't delete the -I$(top_builddir)/rpc/xdr/... bits Change-Id: Iba6ab96b2d0a17c5a7e9f92233993b318858b62e BUG: 1330604 Signed-off-by: Kaleb S KEITHLEY <kkeithle@redhat.com> Reviewed-on: http://review.gluster.org/14085 Tested-by: Niels de Vos <ndevos@redhat.com> Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Niels de Vos <ndevos@redhat.com>

* md-cache: Register the list of xattrs with cache-invalidationPoornima G2016-08-303-10/+125
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue: md-cache caches a specified list of xattrs, and when cache invalidation is enabled, it makes sense to recieve invalidation only when those xattrs are modified by other clients. But the current implementation of upcall is that, it will send invalidation when any of the on-disk xattrs is modified. Solution: md-cache sends a list of xattrs that it is interested in, to upcall by issuing an ipc(). The challenge here is to make sure everytime a brick goes offline and comes back up, the ipc() needs to be issued to the bricks. Hence ipc() is sent from md-cache every time there is a CHILD_UP/CHILD_MODIFIED event. TODO: There will be patches following, in cluster xlators, to implement ipc fop.

Also "UP_PARENT_DENTRY_FLAGS" has to be set only for the fops which shall result in two invalidations requests - one for the inode on which fop is being performed and another on parent entry. In case of CREATE/MKDIR/MKNOD fops, there shall be only one invalidation request sent, that too on parent inode. We send invalidation directly on parent inode's gfid. So there is no necessity to set these flags which when set shall endup invalidating the parent's parent entry.

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.
