* python: remove shebangs of non-main scripts and make others executableNiels de Vos2018-10-021-0/+0
| | | | | | | | | | | | | | | Some of the scripts that have a #!/usr/bin/python3 shebang do not have a main() like function. These scripts will not get executed but only imported. They do not need the shebang. A few others are not installed with 'make install', but do have a main() like function. These scripts are expected to be used by developers for different tasks (mostly code generation). Marking these scripts executable to make it easier to identify them.

(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. Change-Id: Idae21d3b6f58b32372e1daa0d234e491e563198f updates: #411 Signed-off-by: Kaleb S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Note 1) we're not supposed to be using #!/usr/bin/env python, see https://fedoraproject.org/wiki/Packaging:Guidelines?rd=Packaging/Guidelines#Shebang_lines Note 2) we're also not supposed to be using "!/usr/bin/python, see https://fedoraproject.org/wiki/Changes/Avoid_usr_bin_python_in_RPM_Build#Quick_Opt-Out The previous patch (https://review.gluster.org/19767) tried to do too much in one patch, so it was abandoned. This patch does two things: 1) minor cleanup of configure(.ac) to explicitly use python2 2) change all the shebang lines to #!/usr/bin/python2 and add them where they were missing based on warnings emitted during rpmbuild. In a follow-up patch python2 will eventually be changed to python3. Before that python2-isms (e.g. print, string.join(), etc.) need to be converted to python3. Some of those can be rewritten in version agnostic python. E.g. print statements become print() with "from __future_ import print_function". The python 2to3 utility will be used for some of those. Also Aravinda has given guidance in the comments to the first patch for changes. updates: #411 Change-Id: I471730962b2526022115a1fc33629fb078b74338 Signed-off-by: Kaleb S.

* libglusterfs: replace default functions with generated versionsJeff Darcy2015-10-221-0/+80
Replacing repetitive code like this with code generated from a more compact "canonical" definition carries several advantages. * Ease the process of adding new fops (e.g. GF_FOP_IPC). * Ease the process of making global changes to existing fops (e.g. adding "xdata"). * Ensure strict consistency between all of the pieces that must be compatible with each other, through both kinds of changes. What we have right now is just a start. The above benefits will only truly be realized when we use the same definitions to generate stubs, syncops, and perhaps even parts of gfapi or glupy. This same infrastructure can also be used to reduce code duplication and potential for error in many of our translators. NSR already uses a similar technique, using a few hundred lines of templates to generate a few *thousand* lines of code. The ability to make a global "aspect" change (e.g. to quorum checking) in one place instead of seventy has already been demonstrated there. Other candidates for code generation include the AFR/EC transaction infrastructure, or stub creation/resumption in io-threads.
