[issue44070] Regression with relative paths in sys.path in python 3.8.10

[Andy Fiddaman]

Andy Fiddaman  added the comment:

I've just found this while investigating a regression with my project following 
update to 3.9.5. It took me some time to discover that the new test failures 
were due to __file__ now being fully qualified when it wasn't before.

As far as I can tell so far it is just breaking the tests, not the software 
(https://github.com/omniosorg/pkg5) but this doesn't feel like a change that 
should be made in a minor release.

[issue42173] Drop Solaris support

[Andy Fiddaman]

Andy Fiddaman  added the comment:

Jakub's results looks very familiar to me, having been working on python 3.9 on 
illumos.

For OmniOS, we currently skip these tests via --ignorefile:

# wchar_t related failures
*.test_re.ReTests.test_locale_compiled
*.test_re.ReTests.test_locale_caching
# illumos does not support multiple SCM_RIGHTS messages in a packet
*FDPassSeparate*
# These tests fail on illumos and the first consumes a significant
# amount of memory. Investigation required.
test.test_socket.SendfileUsingSendfileTest.testCount
test.test_socket.SendfileUsingSendfileTest.testWithTimeout
test.test_socket.SendfileUsingSendfileTest.testOffset
#
test.test_asyncio.test_sendfile.*
test.test_asyncio.test_subprocess.SubprocessMultiLoopWatcherTests.*


We are also carrying some local patches for the following. Several come from 
Solaris.

- Stop python detecting and using epoll() on illumos

- scheduling priorities can be < 0
https://github.com/citrus-it/omnios-build/blob/python39/build/python39/patches/mod-posix-sched_priority.patch

- differences in sendfile behaviour (improves the situation but is not complete)
https://github.com/citrus-it/omnios-build/blob/python39/build/python39/patches/mod-posix-sendfile.patch

- Enable sendfile for shutil.copy (mismatch between library and testsuite in 
terms of whether sendfile() is enabled on illumos)
https://github.com/citrus-it/omnios-build/blob/python39/build/python39/patches/mod-shutil-sendfile.patch

- Fixes for building the socket module (_XOPEN_SOURCE=600)
https://github.com/citrus-it/omnios-build/blob/python39/build/python39/patches/mod-socket-xpg6.patch

- Emulate clock_gettime(CLOCK_THREAD_CPUTIME_ID)
https://github.com/citrus-it/omnios-build/blob/python39/build/python39/patches/mod-time-threadtime.patch

- PTY patch
https://github.com/citrus-it/omnios-build/blob/python39/build/python39/patches/pty.patch

and a few others, not all of which are suitable for upstream.
https://github.com/citrus-it/omnios-build/tree/python39/build/python39/patches


With all of this in place, the headline test stats for OmniOS Python 3.9 are:

401 tests OK.

24 tests skipped:
test_dbm_gnu test_epoll test_gdb test_idle test_kqueue test_msilib
test_ossaudiodev test_smtpnet test_socketserver test_startfile
test_tcl test_timeout test_tix test_tk test_ttk_guionly
test_ttk_textonly test_turtle test_urllib2net test_urllibnet
test_winconsoleio test_winreg test_winsound test_xmlrpc_net
test_zipfile64

Tests result: SUCCESS

and, additionally, the dtrace tests succeed (we test them separately as they 
require elevated privileges).

[issue42173] Drop Solaris support

Re: Downloads

OmniOS makes modules like 'six' available through its own IPS packaging system 
(which is written in Python) so installations won't show up pypi stats.

six is a core module on the platform so it is installed on 1000s of OmniOS 
machines (and then large numbers of SmartOS, OpenIndiana and tribblix ones too 
- all using the SunOS tag). The numbers aren't going to be in the same league 
as other platforms but the downloads stats definitely don't represent the 
illumos installation base and dependency on Python.

Andy Fiddaman  added the comment:

We at OmniOS (an illumos distribution) are in the process of upgrading to 
Python 3.9 and working on getting tests clean. We're in pretty good shape with 
a few local patches and only having to skip a few tests at the moment, and most 
of those patches should be suitable for integrating generally.

Some of the tests just need adjusting to be aware of the different platform 
(e.g. illumos does not support multiple SCM_RIGHTS messages in a single 
packet), some still need investigating to find the root cause, but the list is 
small.
