cluster/stripe: Mount issues with Stripe xlator

2013-02-03T23:29:59+00:00

Problem:
* 'CONNECTING' is taken as CHILD_UP.
* Sending notifications (default_notify()) for all the events individually
   while mounting.

Solution:
* Consider Child up only after the event CHILD_UP is received.
* Send a single notification for all the children's events only
   while mounting.

build: split CPPFLAGS from CFLAGS

2012-10-03T19:26:45+00:00

Automake provides a separate variable for preprocessor flags
(*_CPPFLAGS). They are already uses in a few places, so make it
consistent and use it everywhere. Note that cflags obtained from
pkg-config often are cppflags, which is why LIBXML2_CFLAGS moves with
into AM_CPPFLAGS, for example.

build: remove useless explicit -fPIC -shared from

2012-10-03T19:24:59+00:00

 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.

build: remove -nostartfiles flag

2012-10-02T20:11:43+00:00

The "-nostartfiles" is a discouraged option and is documented to
potentially result in undesired behavior. Since I see no reason why it
should be in glusterfs, remove it.

build: consolidate common compilation flags into one variable

2012-10-01T23:44:50+00:00

Some -D flags are present in all files, so collect them.
This adds -D${GF_HOST_OS} to some compiler command lines,
but this should not be a problem.

libglusterfs/dict: make 'dict_t' a opaque object

2012-09-06T07:34:15+00:00

* ie, don't dereference dict_t pointer, instead use APIs everywhere
* other than dict_t only 'data_t' should be the valid export from dict.h

* added 'dict_foreach_fnmatch()' API
* changed dict_lookup() to use data_t, instead of data_pair_t

cluster/stripe: handle short writes and errors in writev callback

2012-07-30T18:39:03+00:00

cluster/stripe write callback handling is broken in the event of
server side errors and short writes due to crudely summing up the
return values from each node. This can produce incorrect results
or cause an application to rewrite the wrong portions of a buffer
in an attempt to handle this condition.

Modify cluster/stripe writev handling to record the requested size
of each write and use this data to return the number of consecutive
bytes written from the original request. This allows an application
to retry a write at the point of error (and potentially consume
said error).

cluster: fix crash on link of named pipe in stripe/replicate vol

2012-07-25T22:03:57+00:00

A crash occurs when attempting to link a named pipe on a striped,
replicated volume. The cause for this crash is attempting to deref
a NULL inode pointer in stripe_link_cbk(). The RCA for this bug
uncovered a couple of problems:

- AFR ignores the inode pointer it receives on failure (returning
  NULL).
- stripe assumes the inode pointer is valid on failure.

Either one of these changes addresses the crash, but this patch
includes both changes. AFR is modified to pass along the inode
pointer it receives (which could still be NULL). stripe is
modified to not assume the inode pointer is valid on fop failure.
