The failure definitely seems timing related. This change *seems* to work.
Since the failure isn't doesn't occur consistently, it's hard to tell.
Running these tests on Solaris in this order:
test_urllibnet test_operator test_cgi \
test_isinstance test_future test_ast test_logging
generally caused a failure (about 50% of the time) before the sleep.
I couldn't provoke the failure with the sleep.
This should really be cleaned up by using threading.Events or something
so it is not timing dependent and doesn't hang forever on failure.
test_codecmaps_tw test_importhooks test_socket_ssl
I don't completely understand the cause, but there's a lot of import magic
going on and this is the smallest change which fixes the problem.
want to wait forever if we don't receive the last message. But we also
don't want the test to fail if we shutdown too quickly. I can't reliably
reproduce this failure, so I'm kinda guessing this is the problem.
We'll see if this band-aid helps.
- regenerate ast.py
- add future flags for absolute-import and with-statement so they
(hopefully) properly get set in code-object flags
- try out if/else expressions in actual code for the hell of it.
Seems to generate the same kind of bytecode as the normal compiler.
but without a specified encoding: decoding_fgets() (and decoding_feof()) can
return NULL and fiddle with the 'tok' struct, making tok->buf NULL. This is
okay in the other cases of calls to decoding_*(), it seems, but not in this
one.
This should get a test added, somewhere, but the testsuite doesn't seem to
test encoding anywhere (although plenty of tests use it.)
It seems to me that decoding errors in other places in the code (like at the
start of a token, instead of in the middle of one) make the code end up
adding small integers to NULL pointers, but happen to check for error states
before using the calculated new pointers. I haven't been able to trigger any
other crashes, in any case.
I would nominate this file for a comlete rewrite for Py3k. The whole
decoding trick is too bolted-on for my tastes.
to an unsigned int (and back again) on 64-bit machines, even though the
actual value of the Py_ssize_t variable is way below 31 bits. I suspect
compiler-error.
The culprit was an expression-less yield -- the first apparently in
the standard library. I added a unit test for this.
Also removed the hack to force compilation of test_with.py.
