python3: assume python3 unless building _packages_ on sys without py3

2018-09-27T19:31:53+00:00

The jenkins release-new job runs on a CentOS 7 box, which does not
have python3. As a result it runs (autogen.sh and) configure before
producing the dist tar file, converting all the python3 shebangs to
python2 shebangs in the dist tar file.

Then when that tar file is "carried" to, e.g. Fedora koji build
system to build packages, the shebangs are incorrect, despite having
originally been correct in the git repo.

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.

rpm: add "--with asan" build option

2018-09-11T04:20:13+00:00

RHEL-6 does not have libasan, enabling the "--with asan" option is a
no-op there.

RHEL-7 has an earlier version of libasan, and that does not have the
__asan_init symbol. Test for __asan_report_error in confiure.as instead.

build: Make building of glupy more obvious

2018-09-10T13:16:06+00:00

Yet again glupy..!!

Core changes:
* Provide --disable-glupy(instead of --enable-glupy) since we try to
  build it by default.
* AC_SUBST macro is considered/executed even if it is inside an if
  condition. As a result GLUPY_SUBDIR was always substituted which in
  turn would make compilation enter glupy/ translator sources in absence
  of python{2/3}-devel and fails.

Miscellaneous changes:
* Remove an explicit echo for printing PYTHON version.
* Replace hard coded python version in warning message displayed in
  absence of python{2/3}-devel.
* Redirect pushd and popd output to /dev/null

shebangs changed from /usr/bin/python2 to /usr/bin/python3.
(Reminder, various distribution packaging guidelines require use
of explicit python version and don't allow '#!/usr/bin/env python',
regardless of how handy that idiom may be.)

glusterfs.spec(.in) package python{2,3}-gluster and python2 or
python3 dependencies as appropriate.

configure(.ac):
+ test for and use python2 or python3 as appropriate. If build
  machine has python2 and python3, use python3. Override by
  setting PYTHON=/usr/bin/python2 when running configure.
+ PYTHONDEV_CPPFLAGS from python[23]-config --includes is a
  better match to the original python sysconfig.get_python_inc().
  All those other extraneous flags breaks the build.
+ Only change the shebangs once. Changing them over and over
  again, e.g., during a `make glusterrpms` in extras/LinuxRPM
  just sends make (is it really make that's looping?) into an
  infinite loop. If you figure out why, let me know.
+ Oldest python2 is python2.6 on CentOS 6 and Debian 8 (Jessie).
  Everything else has 2.7 or 3.x
+ logic from https://review.gluster.org/c/glusterfs/+/21050, which
  needs to be removed/merged after that patch is merged.

Builds on CentOS 6, CentOS 7, Fedora 28, Fedora rawhide, and the
mysterious RHEL > 7.

build: add --enable-asan configure options

2018-08-30T05:41:26+00:00

Introduce a `./configure --enable-asan` to build with
`-fsanitize=address -fno-omit-frame-pointer` options. This uses the
libasan.so shared library, so that needs to be available.

While running builds with the ASAN options, several linker issues
surfaced and these have been addressed with this change as well.
Building with --enable-asan has been tested on Fedora 28.

build: use standard PKG_CHECK_MODULES for libxml2 availability

2018-08-16T06:55:21+00:00

In case the development parts of libxml2 are not installed, it was
required to re-run ./autogen.sh to cleanup the cached values for the
check. This is not nice towards users. By using the standard
PKG_CHECK_MODULES for libxml-2.0 the results of the check are not cached
and will be probed again when running ./configure.

build: remove bundled arg-standalone

2018-07-28T12:54:33+00:00

libargp or argp-standalone is available on all commonly used
distributions. There is no need to bundle an unmaintained version of
argp-standalone in this repository anymore.

FreeBSD places the argp.h file in /usr/local/include when
argp-standalone is installed. This path is not added to CPPFLAGS by
default, so thats done in configure.ac as well.

build: remove uuid from contrib/

2018-07-27T17:37:32+00:00

Bundling libuuid is not needed anymore, all current distributions
provide it now.

Some OS's provide their own uuid_*() functions in libc. These may not be
fully compatible with libuuid.so found on Linux systems. In that case,
either e2fsprogs-libuuid can be installed, or support for the native
uuid_*() functions can be added to libglusterfs/src/compat-uuid.h.
