- 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.
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.
added message attribute compared to the previous version of Exception. It is
also a new-style class, making all exceptions now new-style. KeyboardInterrupt
and SystemExit inherit from BaseException directly. String exceptions now
raise DeprecationWarning.
Applies patch 1104669, and closes bugs 1012952 and 518846.
- New semantics for __exit__() -- it must re-raise the exception
if type is not None; the with-statement itself doesn't do this.
(See the updated PEP for motivation.)
- Added context managers to:
- file
- thread.LockType
- threading.{Lock,RLock,Condition,Semaphore,BoundedSemaphore}
- decimal.Context
- Added contextlib.py, which defines @contextmanager, nested(), closing().
- Unit tests all around; bot no docs yet.
- IMPORT_NAME takes an extra argument from the stack: the relativeness of
the import. Only passed to __import__ when it's not -1.
- __import__() takes an optional 5th argument for the same thing; it
__defaults to -1 (old semantics: try relative, then absolute)
- 'from . import name' imports name (be it module or regular attribute)
from the current module's *package*. Likewise, 'from .module import name'
will import name from a sibling to the current module.
- Importing from outside a package is not allowed; 'from . import sys' in a
toplevel module will not work, nor will 'from .. import sys' in a
(single-level) package.
- 'from __future__ import absolute_import' will turn on the new semantics
for import and from-import: imports will be absolute, except for
from-import with dots.
Includes tests for regular imports and importhooks, parser changes and a
NEWS item, but no compiler-package changes or documentation changes.
This was started by Mike Bland and completed by Guido
(with help from Neal).
This still needs a __future__ statement added;
Thomas is working on Michael's patch for that aspect.
There's a small amount of code cleanup and refactoring
in ast.c, compile.c and ceval.c (I fixed the lltrace
behavior when EXT_POP is used -- however I had to make
lltrace a static global).
breaks the parser module, because it adds the if/else construct as well as
two new grammar rules for backward compatibility. If no one else fixes
parsermodule, I guess I'll go ahead and fix it later this week.
The TeX code was checked with texcheck.py, but not rendered. There is
actually a slight incompatibility:
>>> (x for x in lambda:0)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: iteration over non-sequence
changes into
>>> (x for x in lambda: 0)
File "<stdin>", line 1
(x for x in lambda: 0)

SyntaxError: invalid syntax
Since there's no way the former version can be useful, it's probably a
bugfix ;)
- The copy module now "copies" function objects (as atomic objects).
- dict.__getitem__ now looks for a __missing__ hook before raising
KeyError.
- Added a new type, defaultdict, to the collections module.
This uses the new __missing__ hook behavior added to dict (see above).
Google for: eu_ES decimal point
shows that BSD locales had the eu_ES decimal point as
a single quote (') instead of a comma (,).
This was seems to have been fixed 15 months ago, but it's not on our
Mac and presumably others. So skip this broken locale.
test suite.
For urllib2, move the import of gopherlib into the
only function that uses it: users (including the
test suite) certainly shouldn't see a deprecation
warning just because they import urllib2! If they
actually use gopher_open(), fine, _then_ they should
see a deprecation warning.
test_file to fail on Windows in reality (can't delete
a still-open file), but a new bare "except:" hid that
test_file failed on Windows, and leaving behind the
still-open TESTFN caused a cascade of bogus failures
in later tests.
So, close the file, and stop hiding failure to unlink.
readline/readlines/read/readinto, loudly break by raising ValueError, rather
than silently deliver data out of order or hitting EOF prematurely.
Probably not a bugfix candidate, even though it affects no 'working' code.
Based on lsprof (patch #1212837) by Brett Rosen and Ted Czotter.
With further editing by Michael Hudson and myself.
History in svn repo: http://codespeak.net/svn/user/arigo/hack/misc/lsprof
* Module/_lsprof.c is the internal C module, Lib/cProfile.py a wrapper.
* pstats.py updated to display cProfile's caller/callee timings if available.
* setup.py and NEWS updated.
* documentation updates in the profiler section:
- explain the differences between the three profilers that we have now
- profile and cProfile can use a unified documentation, like (c)Pickle
- mention that hotshot is "for specialized usage" now
- removed references to the "old profiler" that no longer exists
* test updates:
- extended test_profile to cover delicate cases like recursion
- added tests for the caller/callee displays
- added test_cProfile, performing the same tests for cProfile
* TO-DO:
- cProfile gives a nicer name to built-in, particularly built-in methods,
which could be backported to profile.
- not tested on Windows recently!
Not sure why/how _handlers/_handlerList is out of sync. This could
indicate a deeper problem.
In test_logging, the only absolutely necessary change to get working
was tcpserver.abort = 1. But we don't want to wait infinitely
to join the threads, so give a 2.0 second timeout.
There doesn't appear to be a need for a local abort variable
in serve_until_stopped, so just use the instance member.
Note the problem is only on HEAD, not in 2.4.
on both Unix (SVR4 and BSD) and Windows. Restores behaviour of passing -1
for anonymous memory on Unix. Use MAP_ANONYMOUS instead of _ANON since
the latter is deprecated according to Linux (gentoo) man pages.
Should we continue to allow mmap.mmap(0, length) to work on Windows?
0 is a valid fd.
Will backport bugfix portions.
tty opened by os.openpty() isn't always a tty according to os.isatty(), when
it's tested inside the process that opened it. Doesn't affect actual
functionality, as using a tty this way is rarely, if ever, useful. Ignoring
the failure allows the test for actual functionality to continue.
Will backport to 2.4-maint.
Expand set of errors caught in set_context(). Some new errors, some
old error messages changed for consistency.
Fixed error checking in generator expression code. The first set of
tests were impossible condition given the grammar. In general, the
ast code uses REQ() for those sanity checks.
Fix some error handling for augmented assignments. As comments in the
code explain, set_context() ought to work here, but I got unexpected
crashes when I tried it. Should come back to this.
Add note to Grammar that yield expression is a special case.
Add doctest cases for SyntaxErrors raised by ast.c.
before the listener was ready (on gentoo x86 buildslave). This
caused the listener to not exit normally since nobody connected to it
(waited in accept()). The exception was raised in the other thread
and the test failed.
This fix doesn't completely eliminate the race, but should make it
near impossible to trigger. Hopefully it's good enough.
SF bug #1403349 solution for email 3.0; some MUAs use the 'file' parameter
name in the Content-Distribution header, so Message.get_filename() should fall
back to using that. Will port to the Python 2.5 trunk.
Also, bump the email package version to 3.0.1 for eventual release. Of
course, add a test case too.
XXX Need to update the documentation.
bugs which cause the interpreter to crash. I'm sure we can find a few
more. Many missing bugs deal with variations on unchecked infinite recursion
(like coerce.py).
cases if TERM isn't set or is unknown (perhaps we should only check if
unset or empty?)
Skip the test if TERM isn't set. This seems to occur when running under
buildbot and presumably cron.

Will backport if it works.
the tests. This stops the confusing/annoying:
No handlers could be found for logger "cookielib"
message we got whenever some test running after test_logging
happened to use cookielib.py (when not using regrtest's -r,
this happened during test_urllib2; when using -r, it varied).
returning 'a' as the delimiter. It now returns '|', but not because I
understood better what the code was supposed to do. Would someone that
understands the idea behind _guess_delimiter() (see its doc string) look to
see if my fallback choice is better than before or if it's just serendipity
that I picked the proper delimiter?
* set sq_repeat and sq_concat to NULL for user-defined new-style
classes, as a way to fix a number of related problems. See
test_descr.notimplemented()). One of these problems was fixed
in r25556 and r25557 but many more existed; this is a general
fix and thus reverts r25556-r25557.
* to avoid having PySequence_Repeat()/PySequence_Concat() failing
on user-defined classes, they now fall back to nb_add/nb_mul if
sq_concat/sq_repeat are not defined and the arguments appear to
be sequences.
* added tests.
Backport candidate.
last field was empty it would strip the delimiter and incorrectly guess that
"" was the delimiter. Reported in c.l.py by Laurent Laporte. Will
backport.
cookielib.LWPCookieJar and .MozillaCookieJar are documented to raise
cookielib.LoadError on attempt to load an invalid cookies file, but
raise IOError instead. Compromise by having LoadError subclass IOError.
This code generated a C assertion:
assert 1, ([s for s in x] +
[s for s in x])
pass
assert was completely broken, it needed to use the proper block.
compiler_use_block() is now no longer used, so remove it.
svn:ignore *.pyc *.pyo

The .py files appear to have been checked in with Windows or inconsistent line
endings. The current check-in disrupts the 'svn blame', but hopefully it is
irrelevant for freshly imported code.
If a line had multiple semi-colons and ended with a semi-colon, we would
loop too many times and access a NULL node. Exit the loop early if
there are no more children.
