base class (WrapperTestCase) instead, and call it repeatedly in the
methods that used to have a loop-over-subcases. Much simpler.
Rename perennial temp variable 't' to 'text'.
<peter@engcorp.com> based on a test script that's been kicking around my
home directory for a couple of months now and only saw the light of day
because I included it when I sent textwrap.py to python-dev for review.
Also, don't call gettempdir() in the default expression for the 'dir'
argument to various functions; use 'dir=None' for the default and
insert 'if dir is None: dir = gettemptir()' in the bodies. That way
the work done by gettempdir is postponed until needed.
[ 587993 ] SET_LINENO killer
Remove SET_LINENO. Tracing is now supported by inspecting co_lnotab.
Many sundry changes to document and adapt to this change.

to the docs is ready to go, but blocked by another JackMacLock in the
doc directory.
do bizarre things to get a temp file, I changed it to use mkstemp instead
of NamedTemporaryFile. This tried to leave the file open while passing
its name to execfile(). On Win2K (but not Win9X), though, a file created
with O_TEMPORARY cannot be opened again, so the test failed with a
permission error when execfile tried to open it. Closer to the truth:
a file created with O_TEMPORARY can be opened again, but only if the
file is also created with SHARE_DELETE access via the Win32 CreateFile()
function. There's no way to get at that from MS's version of libc, though
(we'd have to ditch the "std" C file functions in favor of Win32 API
calls).
Close the bug report again -- this time for Cygwin due to a newlib bug.
See the following for the details:

Note that this commit is only a documentation (i.e., comment) change.
test was written. So boosted the number of "digits" this generates, and
also beefed up the "* / divmod" test to tickle numbers big enough to
trigger the Karatsuba algorithm. It takes about 2 seconds now on my box.
rewrite, by Zack Weinberg). This replaces most code in tempfile.py
(please review!!!) and adds extensive unit tests for it.
This will cause some warnings in the test suite; I'll check those in
soon, and also the docs.
least on OS/2 (see note on SF patch 555085 by A I MacIntyre) but
looks like the test *could* fail on any other platform too -- there's
no guarantee that recv() reads all data.
prints function and module names, which is more informative now that
we repeat some tests in slightly modified subclasses.
Add a test for read() until EOF.
Add test suites for line-buffered (bufsize==1) and a small custom
buffer size (bufsize==2).
Restructure testUnbufferedRead() somewhat to avoid a potentially
infinite loop.
and this broke a Zope "pipelining" test which read multiple responses
from the same connection (this attaches a new file object to the
socket for each response). Added a test for this too.
(I want to do some code cleanup too, but I thought I'd first fix
the problem with as little code as possible, and add a unit test
for this case. So that's what this checkin is about.)
on Windows. The test_sequence() ERROR is easily repaired if we're
willing to add an os.unlink() line to mhlib's updateline(). The
test_listfolders FAIL I gave up on -- I don't remember enough about Unix
link esoterica to recall why a link count of 2 is something a well-
written program should be keenly interested in <wink>.
Added new heapify() function, which transforms an arbitrary list into a
heap in linear time; that's a fundamental tool for using heaps in real
life <wink>.
Added heapyify() test. Added a "less naive" N-best algorithm to the test
suite, and noted that this could actually go much faster (building on
heapify()) if we had max-heaps instead of min-heaps (the iterative method
is appropriate when all the data isn't known in advance, but when it is
known in advance the tradeoffs get murkier).
at random, and replaces the elements at those positions with new random
values. I was pleasantly surprised by how fast this goes! It's hard to
conceive of an algorithm that could special-case for this effectively.
Plus it's exactly what happens if a burst of gamma rays corrupts your
sorted database on disk <wink>.

and age of rampant computer breakins I imagine there are plenty of systems
with telnet disabled. Successful check of at least one getservbyname() call
is required for success
in the stability tests.
Bizarre: this takes 11x longer to run if and only if test_longexp is
run before it, on my box. The bigger REPS is in test_longexp, the
slower this gets. What happens on your box? It's not gc on my box
(which is good, because gc isn't a plausible candidate here).
The slowdown is massive in the parts of test_sort that implicitly
invoke a new-style class's __lt__ or __cmp__ methods. If I boost
REPS large enough in test_longexp, even the test_sort tests on an array
of size 64 visibly c-r-a-w-l. The relative slowdown is even worse in
a debug build. And if I reduce REPS in test_longexp, the slowdown in
test_sort goes away.
test_longexp does do horrid things to Win98's management of user
address space, but I thought I had made that a whole lot better a month
or so ago (by overallocating aggressively in the parser).
If the long is large enough, the return value will be a negative int.
In this case, calling the function a second time won't return the
original value passed in.
imports of test modules now import from the test package. Other
related oddities are also fixed (like DeprecationWarning filters that
weren't specifying the full import part, etc.). Also did a general
code cleanup to remove all "from test.test_support import *"'s. Other
from...import *'s weren't changed.
See there for a description.
Added test case.
Bugfix candidate for 2.2.x, not sure about previous versions:
probably low priority, because virtually no one runs debug builds.
