BUG: 364 (Segfault in io-cache)
URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=364

performance/io-cache: don't use stat got in read_cbk if it is zero-filled.

2009-12-02T09:01:39+00:00

- translators like io-cache, read-ahead return a zero-filled stbuf in
    readv_cbk and usage of zero filled stat for cache validation is not
    correct.

performance/io-cache: remove caching in lookup.

2009-10-15T16:26:37+00:00

- caching file contents in io-cache during lookup is obsolete since quick-read
    does the same work.

io-cache: fix table->max_pri to 1 as the lowest priority

2009-09-16T14:11:41+00:00

patch http://patches.gluster.com/patch/1319/ breaks when no priority
is mentioned in the config. the patch makes ioc_get_priority() return
1 as the value when no priority is given, but ioc_get_priority_list()
was still returning 0 as the max_pri (maximum priority) which would
result in lru list heads not getting initialized

2.0.6 patch for io-cache pattern-matched non-caching

2009-09-15T12:36:16+00:00

Hello all,

here is a small feature patch. Its intention is to give the user more control
over the files performance/io-cache really caches. If the user knows exactly
which files should be cached and which shouldn't there is currently no way to
tell glusterfs _not_ to cache certain pattern. This patch allows you to
disable caching by setting the priority of a pattern to "0". If you do not
give any priority option it works just like before and caches everything.
Honestly I am not totally sure that disabling caching works the way we did it,
please comment.
