of the implementation classes.  (Remove the "Impl" from two names.)

 2002-06-18 18:51:30 +00:00
Fred Drake 074712112b Played contortionist games with the argument_list production so it 
might be easier to understand.
This relates to SF bug #493243, which will be closed.
 2002-06-18 18:42:01 +00:00
Fred Drake 4837fa3a54 \productioncont: Replace leading spaces with   so that it's 
possible to control the indentation of continuation lines.

cfuncline_helper():  Only mark the argument names are <var>, not the
    whole argument list.  This leaves the argument types in the same
    font as the return type.  Based on a casual suggestion from
    Guido.
 2002-06-18 18:30:28 +00:00

Fred Drake 6fc22f6c3d Ensure \verbatiminput always uses a unique filename for each input file in 
the "Download as text" link.  Previously, it could map multiple source files

I've seen \constant{True} in other places.

Closes SF bug #568577.
 2002-06-13 17:54:06 +00:00
Guido van Rossum 11ba094957 Major overhaul of timeout sockets: 
- setblocking(0) and settimeout(0) are now equivalent, and ditto for
  setblocking(1) and settimeout(None).

- Don't raise an exception from internal_select(); let the final call
  report the error (this means you will get an EAGAIN error instead of
  an ETIMEDOUT error -- I don't care).

- Move the select to inside the Py_{BEGIN,END}_ALLOW_THREADS brackets,
  so other theads can run (this was a bug in the original code).

- Redid the retry logic in connect() and connect_ex() to avoid masking
  errors.  This probably doesn't work for Windows yet; I'll fix that
  next.  It may also fail on other platforms, depending on what
  retrying a connect does; I need help with this.

- Get rid of the retry logic in accept().  I don't think it was needed
  at all.  But I may be wrong.
 2002-06-13 15:07:44 +00:00

Michael W. Hudson 5efaf7eac8 This is my nearly two year old patch 
[ 400998 ] experimental support for extended slicing on lists

somewhat spruced up and better tested than it was when I wrote it.

Includes docs & tests.  The whatsnew section needs expanding, and arrays
should support extended slices -- later.
 2002-06-11 10:55:12 +00:00
Fred Drake 55ad7f84a4 Completely revise markup for the list of list methods; the new markup matches 
the semantics and presentation used in the library reference.
Added an explanation of the use of [...] to denote optional arguments, since
this is the only use of this in a signature line.
Closes SF bug #567127.

Fred Drake 6c6d662760 Fix some markup errors and adjust wording slightly. 2002-06-06 21:57:48 +00:00
Guido van Rossum be946bfea7 SF patch 555085 (timeout socket implementation) by Michael Gilfix. 
I've made considerable changes to Michael's code, specifically to use
the select() system call directly and to store the timeout as a C
double instead of a Python object; internally, -1.0 (or anything
negative) represents the None from the API.

I'm not 100% sure that all corner cases are covered correctly, so
please keep an eye on this.  Next I'm going to try it Windows before
Tim complains.

No way is this a bugfix candidate. :-)
 2002-06-06 21:51:01 +00:00
Martin v. Löwis 446a25fa3c Patch 473512: add GNU style scanning as gnu_getopt. 2002-06-06 10:58:36 +00:00
Fred Drake 293dd4b77b Fix up Guido's markup. 2002-06-04 16:25:57 +00:00
Walter Dörwald 474458da48 Add constants BOM_UTF8, BOM_UTF16, BOM_UTF16_LE, BOM_UTF16_BE, 
BOM_UTF32, BOM_UTF32_LE and BOM_UTF32_BE that represent the Byte
Order Mark in UTF-8, UTF-16 and UTF-32 encodings for little and
big endian systems.

The old names BOM32_* and BOM64_* were off by a factor of 2.

This closes SF bug http://www.python.org/sf/555360
 2002-06-04 15:16:29 +00:00
Guido van Rossum 92cf95f45b Addressed SF bug 421973 (finally). 
Rewrote the subsection on coercion rules (and made it a proper
subsection, with a label).  The new section is much less precise,
because precise rules would be too hard to give (== I don't know what
they are any more :-).  OTOH, the new section gives much more
up-to-date information.

Also noted that __coerce__ may return NotImplemented, with the same
meaning as None.

I beg Fred forgiveness: my use of \code{} is probably naive.  Please
fix this and other markup nits.  An index entry would be nice.

This could be a 2.2 bugfix candidate, if we bother about old docs
(Fred?)
 2002-06-03 19:06:41 +00:00
Guido van Rossum 59b2a74c75 SF bug 533625 (Armin Rigo). rexec: potential security hole 
If a rexec instance allows writing in the current directory (a common
thing to do), there's a way to execute bogus bytecode.  Fix this by
not allowing imports from .pyc files (in a way that allows a site to
configure things so that .pyc files *are* allowed, if writing is not
allowed).

I'll apply this to 2.2 and 2.1 too.
 2002-05-31 21:12:53 +00:00

Fred Drake bfc18bdf03 Integrated SF patch #539487 by Matthias Klose: 
This patch adds Milan Zamazal's conversion script and

Fred Drake fe3db7d6f0 Work around limitation of Cygwin Perl: To avoid a permission denial, we need 
to do the inplace-edit with a backup file.  A quick test leads me to
believe this is sufficient to allow building the documentation on Cygwin;
a full test is in progress.

Fred Drake 56aa6280f6 list_documented_items(): Basic implementation. 
This still does not work well since ctags does not do a good job with the

Fred Drake 432425e834 Small markup adjustments for consistency. 2002-04-29 15:17:16 +00:00
Tim Peters 81b9251d59 Mostly in SequenceMatcher.{__chain_b, find_longest_match}: 
This now does a dynamic analysis of which elements are so frequently
repeated as to constitute noise.  The primary benefit is an enormous
speedup in find_longest_match, as the innermost loop can have factors
of 100s less potential matches to worry about, in cases where the
sequences have many duplicate elements.  In effect, this zooms in on
sequences of non-ubiquitous elements now.

While I like what I've seen of the effects so far, I still consider
this experimental.  Please give it a try!

Tim Peters 5de9842b34 Repair widespread misuse of _PyString_Resize. Since it's clear people 
don't understand how this function works, also beefed up the docs.  The
most common usage error is of this form (often spread out across gotos):

	if (_PyString_Resize(&s, n) < 0) {
		Py_DECREF(s);
		s = NULL;
		goto outtahere;
	}

The error is that if _PyString_Resize runs out of memory, it automatically
decrefs the input string object s (which also deallocates it, since its
refcount must be 1 upon entry), and sets s to NULL.  So if the "if"
branch ever triggers, it's an error to call Py_DECREF(s):  s is already
NULL!  A correct way to write the above is the simpler (and intended)

	if (_PyString_Resize(&s, n) < 0)
		goto outtahere;

Bugfix candidate.
