write-behind: fixes issues with iobuf length for large writes

2012-12-13T22:46:42+00:00

Use of an unsigned type in some calculations of size would lead to segmentation
faults, if several large adjacent writes came in concurrently.

Also, improves buffer allocation code to take the size required into account.

Credits for the patch go to Amar.

write-behind: use uint64_t for overlap comparison

2012-10-13T17:41:59+00:00

off_t is 'long int' (signed word) and therefore ULLONG_MAX - 1

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.
