build: cleanup xlator link, --no-undefined, libuuid

2018-09-12T14:38:13+00:00

While attempting to build a (pre-)5.0 of glusterfs on Ubuntu
bionic and cosmic, it became apparent that there are some gremlins
hiding in the combination of the xlator export-symbols, the newish
addition of -Wl,--no-undefined, and the new switch to libuuid from
the old contrib/uuid.

Note: even though Fedora 28 (and later) and Ubuntu bionic (and
later) have the same nominal version of libtool, the Fedora version
appears to do a better job of recursing through dependencies to
determine the libraries to link with.

Examination of the build logs showed that despite appearing to work
on Fedora, not all xlators and shared libs were linked with -Wl,
--no-undefined, and -luuid. And in the case of the gnfs xlator, it
was not only not linked with -Wl,--no-undefined but alsos not linked
with -lgfxdr and -lgfrpc.

Added GF_XLATOR_LDFLAGS, similar to GF_XLATOR_DEFAULT_LDFLAGS.
GF_XLATOR_DEFAULT_LDFLAGS is for xlators that export/expose the
default or common set of symbols. GF_XLATOR_LDFLAGS is for those
remaining xlators that export/expose non-default symbols, e.g. dht
and glupy. This removes the need in the future to add things like
$(UUID_LIBS) to every xlator's Makefile.am. Just add it to
GF_XLATOR_LDFLAGS and GF_XLATOR_DEFAULT_LDFLAGS in configure.ac
and you're done.

This patch was tested on Fedora 28 (build, rpmbuild), Fedora
Rawhide/30 (rpmbuild), RHEL8 (rpmbuild), CentOS7 (rpmbuild), Fedora
koji --scratch build for f30/rawhide, and a Launchpad build for
Ubuntu cosmic/18.10.

Move to GF_MALLOC() instead of GF_CALLOC() when possible

It doesn't make sense to calloc (allocate and clear) memory
when the code right away fills that memory with data.
It may be optimized by the compiler, or have a microscopic
performance improvement.

In some cases, also changed allocation size to be sizeof some
struct or type instead of a pointer - easier to read.
In some cases, removed redundant strlen() calls by saving the result
into a variable.

1. Only done for the straightforward cases. There's room for improvement.
2. Please review carefully, especially for string allocation, with the
terminating NULL string.

Only compile-tested!

.. and allocate memory as much as needed.

xlators/nfs/server/src/mount3.c :

Don't blindly allocate PATH_MAX, but strlen() the string and allocate
appropriately.
Also, align error messges.

NFS server (mount3.c, nfs-inodes.c): strncpy()->sprintf(), reduce strlen()'s

2018-08-31T06:17:20+00:00

xlators/nfs/server/src/mount3.c
xlators/nfs/server/src/nfs-inodes.c

strncpy may not be very efficient for short strings copied into
a large buffer: If the length of src is less than n,
strncpy() writes additional null bytes to dest to ensure
that a total of n bytes are written.

Instead, use snprintf().

Compile-tested only!

All: remove memset() before sprintf()

2018-08-14T05:15:04+00:00

It's not needed.
There's a good chance the compiler is smart enough to remove it
anyway, but it can't hurt - I hope.
