* Require Python 3 and remove support for Python 2.Ben Pfaff2019-09-271-127/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Python 2 reaches end-of-life on January 1, 2020, which is only a few months away. This means that OVS needs to stop depending on in the next release that should occur roughly that same time. Therefore, this commit removes all support for Python 2. It also makes Python 3 a mandatory build dependency. Some of the interesting consequences: - HAVE_PYTHON, HAVE_PYTHON2, and HAVE_PYTHON3 conditionals have been removed, since we now know that Python3 is available. - $PYTHON and $PYTHON2 are removed, and $PYTHON3 is always available. - Many tests for Python 2 support have been removed, and the ones that depended on Python 3 now run unconditionally. This allowed several macros in the testsuite to be removed, making the code clearer. This does make some of the changes to the testsuite files large due to indentation level changes. - #! lines for Python now use /usr/bin/python3 instead of /usr/bin/python. - Packaging depends on Python 3 packages.

* tests: Always use --no-chdir with --detach.Ben Pfaff2018-11-191-12/+12
| | | | | | | | | With --detach but not --no-chdir, core files and Address Sanitizer logs don't go into the testsuite directory but end up dropped because it tries to write them in the root directory. Acked-by: Mark Michelson <mmichels@redhat.com> Signed-off-by: Ben Pfaff <blp@ovn.org>
* Permit to build OVS with only Python3 installedTimothy Redaelli2018-07-241-7/+7
| | | | | | | | | | | | | | | | | | This commit renames HAVE_PYTHON to HAVE_PYTHON2 and PYTHON to PYTHON2 and adds HAVE_PYTHON and PYTHON with a different semantics: - If PYTHON environment variable is set, use it as PYTHON - If a python2 interpreter is available, PYTHON became the python2 interpreter - If a python3 interpreter is available, PYTHON became the python3 interpreter PYTHON is only used to run the python scripts needed by the build system NOTE: Since currently most of the utilities and bugtool doesn't support Python3, they're installed only if python2 is available. This will be fixed in later commits. Signed-off-by: Timothy Redaelli <tredaelli@redhat.com> Signed-off-by: Ben Pfaff <blp@ovn.org>

* vlog.at: Avoid using GNU sed extensionYAMAMOTO Takashi2016-03-241-2/+2
| | | | | | | | | | | | | | | BRE alternative (\|) is an GNU sed extension. [1] It isn't available in NetBSD sed. [1] http://www.gnu.org/software/sed/manual/sed.html#Regular-Expressions regexp1\|regexp2 Matches either regexp1 or regexp2. Use parentheses to use complex alternative regular expressions. The matching process tries each alternative in turn, from left to right, and the first one that succeeds is used. It is a GNU extension.

| | | | | | | | | | A lot of tests need to initialize the OVS_RUNDIR, OVS_LOGDIR, etc. variables to point to the directory in which the tests run. Until now, each of them has had to do this individually, which is redundant. This commit starts to do this automatically.

* vlog: Ability to override the default log facility.Gurucharan Shetty2015-01-281-0/+63
| | | | | | | | | | | | | | | When Open vSwitch is run in hundreds of hypervisors, it is useful to collect log messages through log collectors. To collect log messages like this, it is useful to log them in a particular RFC5424 facility in the local system. The log collectors can then be used to collect logs anytime desired. This commit provides a sysadmin the ability to specify the facility through which the log messages are logged.

* vlog: Rename the currently used term 'facility' as 'destination'.Gurucharan Shetty2015-01-081-3/+3
| | | | | | | | | | | | In OVS, we currently use the term 'facility' to mean the place where we log (syslog, console or file). In Linux's syslog() and rfc5424, the term 'facility' is used to specify what type of program is logging the message (e.g: LOG_DAEMON). This causes confusion while reading vlog's code. This commit changes the term 'facility' to 'destination'. Signed-off-by: Gurucharan Shetty <gshetty@nicira.com> Acked-by: Ben Pfaff <blp@nicira.com>
* Python Logging Formatting ImprovementsDave Tucker2014-04-281-37/+45
| | | | | | | | | | | | | | | | | | The Open vSwitch daemons written in C support user-configured logging patterns as described in ovs-appctl(8). This commit adds this capability to the daemons written in Python. - Add a '__log_patterns' attribute to the Vlog class - Populate this using the default patterns in ovs-appctl(8) - Add a '__start_time' attribute to the Vlog class to support '%r' - Update the '_log' method to build the log message according to the pattern - Add a 'set_pattern' method to allow the default patterns to be changed - Update 'set_levels_from_string' to support setting the pattern from a string Signed-off-by: Dave Tucker <dave@dtucker.co.uk> Signed-off-by: Ben Pfaff <blp@nicira.com>

* tests: New m4 macro ON_EXIT to add a cleanup action.Ben Pfaff2012-08-201-5/+4
| | | | | | | | | | | | | | | Several of the tests start daemons and then need to make sure that the daemons get killed when the test completes, even if it completes in the middle due to an early failure. Until now, they have been using manual shell "trap" calls to do this. This works well enough for simple cases, but sometimes multiple macros start daemons in a single test, and then each "trap" has to be carefully written to kill off the daemons for the previously invoked macros. This commit introduces a new macro ON_EXIT whose use is composable: each call appends a new action to the ones already specified. Signed-off-by: Ben Pfaff <blp@nicira.com>

* python: Create new vlog module.Ethan Jackson2011-09-271-0/+105
Currently, each python daemon has to come up with it's own logging solution. These logging strategies are not consistent across the python code or with the C vlog module. This patch adds a new logging module which hopes to solve the problem. This new module generates log messages in a manner consistent with the C code. Furthermore, it can easily be extended to support things like rate limiters in the future. This patch does not update any python code to use the new module.
