trying to return a complete line even if a size parameter was given (see
http://www.python.org/sf/1076985). This leads to buffer overflows with long
source lines under Windows if e.g. cp1252 is used as the source encoding.
This patch reverts the behaviour of readline() to something that behaves more
like Python 2.3: If a size parameter is given, read() is called only once.
As a side effect of this, readline() now supports all types of linebreaks
supported by unicode.splitlines().
Note that the tokenizer is still broken and it's possible to provoke segfaults
(see http://www.python.org/sf/1089395).
This is to avoid a problem that inconsistently comes up where the environment
variable is unset while the Makefile clearly has the values set and are used
during ``make``.
Closes bug #1081045.
* Improve algorithm -- no more O(n) steps except sched.cancel().
* Improve thread safety of sched.run() and sched.empty()
(other threads could alter the queue between the time the queue was
first checked and when the lead event was deleted).
* Localize variable access in sched.run() to minimize overhead.
* Added missing error checks.
* Fixed O(n**2) growth pattern. Modeled after lists to achieve linear
amortized resizing. Improves construction of "tuple(it)" when "it" is
large and does not have a __len__ method. Other cases are unaffected.
more. Thanks to Simon Percivall!
The patch makes changes to inspect.py in two places:
* the pattern to match against functions at line 436 is
modified: lambdas should be matched even if not
preceded by whitespace, as long as "lambda" isn't part
of another word.
* the BlockFinder class is heavily modified. Changes are:
- checking for "def", "class" or "lambda" names
before setting self.started to True. Then checking the
same line for word characters after the colon (if the
colon is on that line). If so, and the line does not
end with a line continuation marker, raise EndOfBlock
immediately.
- adding self.passline to show that the line is to be
included and no more checking is necessary on that
line. Since a NEWLINE token is not generated when a
line continuation marker exists, this allows getsource
to continue with these functions even if the following
line would not be indented.
Also add a bunch of
'quite-unlikely-to-occur-in-real-life-but-working-anyway' tests.
Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
alias file); the encoding lookup was enhanced to use Python's
encoding alias table
As sige-effect, this fixes SF bug [ 1080864 ] locale.py doesn't recognize
valid locale setting.
