* performance/quick-read: don't try to validate again if qr_readv is called ↵Raghavendra G2010-04-272-9/+21
| | | | | | | | | | just after validation. Signed-off-by: Raghavendra G <raghavendra@gluster.com> Signed-off-by: Anand V. Avati <avati@dev.gluster.com> BUG: 852 (QR cache-timeout 0 causes high CPU usage and app hangs) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=852

* performance/quick-read: make use of nanosecond resolution of mtime to decide ↵Raghavendra G2010-04-081-2/+6
| | | | | | | | | | whether to keep cache or not. Signed-off-by: Raghavendra G <raghavendra@gluster.com> Signed-off-by: Anand V. Avati <avati@dev.gluster.com> BUG: 801 (Direct io-mode support and related changes in caching translators.) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=801
* performance/quick-read: change the maximum value of max-file-size to 1000KB ↵Raghavendra G2009-11-281-4/+4
| | | | | | | | | | | | | | | from 1MB. - protocol restricts the maximum buffer size that can be received over network to 1MB. Since the buffer holding reply of lookup should also contain the lookup header and other key/value pairs of xattr_reply dict, the maximum file size that can be fetched through dictionary cannot be equal to 1MB.

Avati <avati@dev.gluster.com> BUG: 419 (Issues with writing files of size >= 1MB) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=419

* performance/quick-read: frame->local need not be set in qr_open_cbk.Raghavendra G2009-10-151-4/+1
| | | | | | | | | | - local is used only by certain operations and hence it need not be set by all the operations invoking open. Signed-off-by: Anand V. Avati <avati@dev.gluster.com> BUG: 323 (fd leak with quick-read loaded in translator tree) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=323
* performance/quick-read: flush should proceed with winding if fd-context is ↵Raghavendra G2009-10-151-2/+1
| | | | | | | | | | | | not found. - if the fd-context is not set, quick-read has no role to play other than just passing down the call to underlying translators. Signed-off-by: Anand V.

* performance/quick-read: refine logic of qr_readv.Raghavendra G2009-09-221-3/+14
| | | | | | | | | | - An extra vector was being allocated when the number of bytes being read from cache were equal to the iobuf size. Signed-off-by: Anand V.

* performance/quick-read: optimizations to lookupRaghavendra G2009-09-221-24/+49
| | | | | | | | | | | - qr_lookup not to send request for file-content if the cache is already present during revalidates. - flush the cache in qr_lookup_cbk if the cache is not in sync with the file.

* performance/quick-read: refine the logic in qr_lookup.Raghavendra G2009-09-221-40/+54
| | | | | | | | | | | | | - a new size has to be set in xattr_req only if (quick-read is configured with a maximum file size limit && ((xattr_req does not have a request key for getting content) || (the size requested in xattr_req is not equal to configured size in quick-read))) Signed-off-by: Anand V.

* performance/quick-read: access glusterfs_ctx from xlator instead of using ↵Raghavendra G2009-09-171-1/+1
| | | | | | | | | | | | | | glusterfs_get_ctx - since glusterfs_get_ctx gets the global context pointer, there can be problems in a multithreaded application running on libglusterfsclient doing multiple glusterfs_inits. Hence use context specific to the current xlator tree stored in each xlator object. Signed-off-by: Anand V.
