The hppa ubuntu box sometimes hangs forever in these tests. My guess
is that the wait is failing for some reason. Use WNOHANG, so we won't
wait until the buildbot kills the test suite.
I haven't been able to reproduce the failure, so I'm not sure if
this will help or not. Hopefully, this change will cause the test
to fail, rather than hang. That will be better since we will get
the rest of the test results. It may also help us debug the real problem.
*** The reason this originally failed was because there were many
zombie children outstanding before rev 47158 cleaned them up.
There are still hangs in test_subprocess that need to be addressed,
but that will take more work. This should close some holes.
Add a new function uses_seh() to the _ctypes extension module. This
will return True if Windows Structured Exception handling (SEH) is
used when calling functions, False otherwise.
str() or repr()) would work, just not multi-value tuples. Probably not a
backport candidate, since it changes the behaviour of passing a
single-element tuple:
>>> string.Template("$foo").substitute(dict(foo=(1,)))
'(1,)'
versus
'1'
will return True if Windows Structured Exception handling (SEH) is
used when calling functions, False otherwise.
Currently, only MSVC supports SEH.
Fix the test so that it doesn't crash when run with MingW compiled
_ctypes. Note that two tests are still failing when mingw is used, I
suspect structure layout differences and function calling conventions
between MSVC and MingW.
handler would cause a segfault. This merges in Expat's lib/xmlparse.c
revisions 1.154 and 1.155, which fix this and a closely related problem
(the later does not affect Python).
Moved the crasher test to the tests for xml.parsers.expat.
be called at the end of each test that spawns children (perhaps it
should be called from regrtest instead?). This will hopefully prevent
some of the unexplained failures in the buildbots (hppa and alpha)
during tests that spawn children. The problems were not reproducible.
There were many zombies that remained at the end of several tests.
In the worst case, this shouldn't cause any more problems,
though it may not help either. Time will tell.
(modified patch by Sam Ruby; changed to use separate REs for start and end
tags to reduce matching cost for end tags; extended tests; updated to avoid
breaking previous changes to support IPv6 addresses in unquoted attribute
values)
consistent with os.wait() returning immediately because some other
subprocess had previously exited; the test suite then immediately
tries to lock the mailbox and gets an error saying it's already
locked.
To fix this, do a waitpid() so the test suite only continues once
the intended child process has exited.
remove the flock() calls.
On FreeBSD, the two methods lockf() and flock() end up using the same
mechanism and the second one fails. A Linux man page claims that the
two methods are orthogonal (so locks acquired one way don't interact
with locks acquired the other way) but that clearly must be false.
Without this patch IDLE will get unresponsive when you open the debugger
window on OSX. This is both using the system Tcl/Tk on Tiger as the latest
universal download from tk-components.sf.net.
('[' and ']' were not accepted in unquoted attribute values)
- cleaned up tests of character and entity reference decoding so the
tests cover the documented relationships among handle_charref,
handle_entityref, convert_charref, convert_codepoint, and
convert_entityref, without bringing up Unicode issues that sgmllib
cannot be involved in
both a subclass of Warning and a subclass of types.ClassType. The latter is no
longer true thanks to new-style exceptions.
Closes bug #1510580. Thanks to AMK for the test.
The problem of checking too eagerly for recursive calls is the
following: if a RuntimeError is caused by recursion, and if code needs
to normalize it immediately (as in the 2nd test), then
PyErr_NormalizeException() needs a call to the RuntimeError class to
instantiate it, and this hits the recursion limit again... causing
PyErr_NormalizeException() to never finish.
Moved this particular recursion check to slot_tp_call(), which is not
involved in instantiating built-in exceptions.
Backport candidate.
constructor, meaning it is treated as *args, not as a single argument. This
means using the 'message' attribute won't work (until Py3K comes around),
and so one must grab from 'arg' to get the error number.
os.environ (setting envar COLUMNS), which at least caused
test_float_default() to fail if the tests were run more than once.
This repairs the test_optparse -R failures Neal reported on
python-dev. It also explains some seemingly bizarre test_optparse
failures we saw a couple weeks ago on the buildbots, when
test_optparse failed due to test_file failing to clean up after
itself, and then test_optparse failed in an entirely different
way when regrtest's -w option ran test_optparse a second time.
It's now obvious that make_parser() permanently changing os.environ
was responsible for the second half of that.

issues that crop up from time to time, but this change seems to have been
pretty stable (no spurious warnings) for about a week.
Other modules which use threads may require similar use of
threading_setup/threading_cleanup from test_support.
of this test. It probably still requires more disk space
than most buildbots have, and in any case is still so
intrusive that if we don't find another way to test this I'm
taking my buildbot offline permanently ;-)
This will hopefully get the buildbots to pass. Not sure this
test will be feasible or even work. But everything is red now,
so it can't get much worse.
now works reliably. It has been updated to use automatic BerkeleyDB
deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
database calls that would previously deadlock. [SF python bug #775414]
until Gerhard has time to fully debug the issue. This affects versions
before 3.2.1 (possibly only versions earlier than 3.1.3).
Based on discussion on python-checkins.
This backs out the test changes in 46962 which prevented crashes
by not running the tests via a version check. All the version checks
added in that rev were removed from the tests.
Code was added to the error handler in connection.c that seems
to work with older versions of sqlite including 3.1.3.
SQLite versions.
- Added version checks in test suite so that we don't execute tests that we
know will fail with older (buggy) SQLite versions.
Now, all tests should run against all SQLite versions from 3.0.8 until 3.3.6
(latest one now). The sqlite3 module can be built against all these SQLite
versions and the sqlite3 module does its best to not trigger bugs in SQLite,
but using SQLite 3.3.3 or later is recommended.
adjacent triples in the result list describe non-adjacent matching
blocks. That's _nice_ to have, and Guido said he wanted it.
Not a bugfix candidate: Guido or not ;-), this changes visible
endcase semantics (note that some tests had to change), and
nothing about this was documented before. Since it was working
as designed, and behavior was consistent with the docs, it wasn't
"a bug".
arguments in reverse, the interpreter would infinitely recourse trying to get a
coercion that worked. So put in a recursion check after a coercion is made and
the next call to attempt to use the coerced values.
Fixes bug #992017 and closes crashers/coerce.py .
Heavily revised, comprising revisions:
46640 - original trunk revision (backed out in r46655)

not related to these changes).
more comments about why it's this way at all; and removed what looked
like needless expense (sorting (i, j, k) triples directly should give
exactly the same order as sorting (i, (i, j, k)) pairs).
when running with -O.
test_simple_validation_error still fails under -O. That appears to be because
wsgiref's validate.py uses `assert` statements all over the place to check
arguments for sanity. That should all be changed (it's not a logical error
in the software if a user passes bogus arguments, so this isn't a reasonable
use for `assert` -- checking external preconditions should generally raise
ValueError or TypeError instead, as appropriate).
a search path setup, some of these hosts resolve to the wrong address.
By appending a period to the hostname, the hostname should only resolve
to what we want it to resolve to. Hopefully this doesn't break different bots.
Also add more info to failure message to aid debugging test failure.

versus generator period. While this was a real weakness of the
older WH generator for lists with just a few dozen elements,
and so could potentially bite the naive ;-), the Twister should
show excellent behavior up to at least 600 elements.
Module docstring: reflowed some jarringly short lines.
Summary of changes:
- support for 'variable sized' data
- support for anonymous structure/union fields
- fix severe bug with certain arrays or structures containing more than 256 fields
