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.

core/various: python3 compat, prepare for python2 -> python3

2018-06-04T19:55:35+00:00

see https://review.gluster.org/#/c/19788/,
    https://review.gluster.org/#/c/19871/, and
    https://review.gluster.org/#/c/19952/

This patch adds version agnostic imports for urllib, cpickle,
socketserver, _thread, queue, etc., suggested by Aravinda in
https://review.gluster.org/#/c/19767/1

Note: Fedora packaging guidelines require explicit shebangs, so
popular practices like #!/usr/bin/env python and #!/usr/bin/python
are not allowed; they must be #!/usr/bin/python2 or #!/usr/bin/python3

Note: Selected small fixes from 2to3 utility. Specifically apply,
basestring, funcattrs, idioms, numliterals, set_literal, types, urllib,
and zip have already been applied.

Note: these 2to3 fixes report no changes are necessary: exec, execfile,
exitfunc, filter, getcwdu, intern, itertools, metaclass, methodattrs, ne,
next, nonzero, operator, paren, raw_input, reduce, reload, renames, repr,
standarderror, sys_exc, throw, tuple_params, xreadlines.

Any 2to3 fixes not in the above two lists have more extensive changes
which will follow in separate patches.

most unicode changes suggested by 2to3 will need to be applied at the
same time as changing the shebangs from python2 to python3. Prashanth
notes that unicode strings in py2 need 'u' prefix; unicode strings in
py3 3.0, 3.1, and 3.2 a 'u' prefix will throw an error, but in py3 3.3+
it is legal (or just ignored). All Linux dists we care about have 3.3
or later so we can leave 'u' prefixes on unicode strings.

core/build/various: python3 compat, prepare for python2 -> python3

2018-04-12T11:04:27+00:00

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.

tools/glusterfind: add --end-time option

2017-06-12T05:14:08+00:00

Add optional --end-time argument to be used with --since-time
when using the "query" command.

"start" and "end" times are passed in the command-line to
changelog.py only if --full has not been specified on command-line.
-1 is passed to changelog.py as end time if user has not supplied
--end-time on command-line.

brickfind.py:
Remove unused "start" command-line argument.

Also:
Minor indentation changes to keep flake8-2.7 happy.

tools/glusterfind: kill remote processes and separate run-time directories

2016-10-25T12:00:54+00:00

Problem #1:
Hitting CTRL+C leaves stale processes on remote nodes if glusterfind pre
has been initiated.

Solution #1:
Adding "-t -t" to ssh command-line forces pseudo-terminal to be assigned
to remote process. When local process receives Keyboard Interrupt,
SIGHUP is immediately conveyed to the remote terminal causing remote
changelog.py process to terminate immediately.

Problem #2:
Concurrent glusterfind pre runs are not possible on the same glusterfind
session in case of a runaway process.

Solution #2:
glusterfind pre runs now add random directory name to the working
directory to store and manage temporary database and changelog
processing.
If KeyboardInterrupt is received, the function call
run_cmd_nodes("cleanup", args, tmpfilename=gtmpfilename)
cleans up the remote run specific directory.

Patch:
7571380 cli/xml: Fix wrong XML format in volume get command
broke "gluster volume get  changelog.rollover-time --xml"
Now fixed function utils.py::get_changelog_rollover_time()

Fixed spurious trailing space getting written if second path is empty in
main.py::write_output()
Fixed repetitive changelog processing in changelog.py::get_changes()

tools/glusterfind: Handling Unicode file names

2016-03-30T13:37:18+00:00

Unicode filenames handled cleanly with this patch. Changelog
files and output files are opened with utf-8 encoding using codecs.open.

urllib.quote_plus and unquote_plus will not handle Unicode so, encode
Unicode to 8-bit string version before calling unquote. urllib.quote_plus
requires 8-bit string itself so do not decode to Unicode if we need to use
quote_plus(when --no-encode=false). Decode to unicode in --no-encode is set.

tools/glusterfind: New option --no-encode

2016-02-26T10:11:08+00:00

New option added to skip encoding path in output file. Also handled
Unicode strings.

File paths can have newline characters, to differentiate between each
path patch is encoded according to
RFC3986(https://www.ietf.org/rfc/rfc3986.txt). Due to this consumer
applications have to decode the path before consuming it. With this
option Paths are not encoded, can be directly consumed by
applications.

Unicode encoding is handled automatically
