booster: Fix build problems with various libtool versions

2009-06-30T22:24:53+00:00

We've been facing a problem on some test systems where the
booster.so is built by libtool as an executable rather than
a dynamically loadable library.

This problem is probably caused by it seeing a _init function in
the source. This is the name of the libc initiliazation
function so it could be the source of the problem.

In any case, ld-preloadable libraries must not have a function
called _init, instead they need to have __attribute ((constructor))
as the attribute for any and all functions the library wants
executed before the program's main(). Our earlier approach was
inherently problematic.
This commit also cleans up the booster Makefile for better
build behaviour. Credit: Harsha.

booster: Another attempt to fix 32 and 64 bit interoperability

2009-06-30T21:55:49+00:00

With this patch, we might have finally arrived at a solution
to the problem of function definition conflicts between
our functions and those of libc while over-riding the libc versions.

This commit defines functions which do not conflict with libc,
then it uses libc's own macro to redirect/rename these functions
to the actual sys call names in the binary.

booster: Add new booster-specific fd-table

2009-06-30T21:36:28+00:00

The reason we need a booster specific fd-table is because
the libglusterfs fd-table has come to a point where it is
optimized for libglusterfs-style of fd allocations.
This conflicts with the way booster requires fds to be allocated
so this commit brings in a re-based version of a booster-specific
fd-table written by Raghu.

booster: fix memory corruption in booster_cleanup

2009-06-30T21:36:26+00:00

- calling glusterfs_umount_all leads to memory corruption.
    hence commenting out for timebeing.

booster: remove mount table which maps a path to glusterfs handler.

2009-06-30T21:36:23+00:00

- if there are any glusterfs mounts(real, not virtual) which are not specified
    through booster-fstab those mounts are also added to the virtual mountpoint
    list of libglusterfsclient. This also removes the mount table in booster and
    all the mounts whether they are real or virtual are handled by
    libglusterfsclient.
