Walter Dörwald 7a6dc139de Fix for SF bug #1175396: readline() will now read one more character, if
the last character read is "\r" (and size is None, i.e. we're allowed to
call read() multiple times), so that we can return the correct line ending
(this additional character might be a "\n").

If the stream is temporarily exhausted, we might return the wrong line ending
(if the last character read is "\r" and the next one (after the byte stream
provides more data) is "\n", but at least the atcr member ensure that we
get the correct number of lines (i.e. this "\n" will not be treated as
another line ending.)

Will backport to 2.4.

Walter Dörwald 9fa0946771 Fix and test for SF bug #1098990: codec readline() splits lines apart. 2005-01-10 12:01:39 +00:00
Walter Dörwald e57d7b179a The changes to the stateful codecs in 2.4 resulted in StreamReader.readline()
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).

Hye-Shik Chang af5c7cff56 SF #1048865: Fix a trivial typo that breaks StreamReader.readlines() 2004-10-17 23:51:21 +00:00
Walter Dörwald 69652035bc SF patch #998993: The UTF-8 and the UTF-16 stateful decoders now support
decoding incomplete input (when the input stream is temporarily exhausted).
codecs.StreamReader now implements buffering, which enables proper
readline support for the UTF-16 decoders. codecs.StreamReader.read()
has a new argument chars which specifies the number of characters to
return. codecs.StreamReader.readline() and codecs.StreamReader.readlines()
have a new argument keepends. Trailing "\n"s will be stripped from the lines
if keepends is false. Added C APIs PyUnicode_DecodeUTF8Stateful and
PyUnicode_DecodeUTF16Stateful.

Neal Norwitz 6ec0a8ab93 sys was already imported, remove second import 2002-12-30 23:36:02 +00:00
Marc-André Lemburg b28de0d79f Patch to make _codecs a builtin module. This is necessary since
Python 2.3 will support source code encodings which rely on the
builtin codecs being available to the parser.

Remove struct dependency from codecs.py

Walter Dörwald 7f82f7955e Add missing documentation for the PEP 293 functionality to

2002-11-19 21:42:53 +00:00
Walter Dörwald 4dbf192f2b Add next() and __iter__() methods to StreamReader, StreamReaderWriter
and StreamRecoder.

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.

Raymond Hettinger 54f0222547 SF 563203. Replaced 'has_key()' with 'in'. 2002-06-01 14:18:47 +00:00
Martin v. Löwis b786e61b1c Set default value for readlines.sizehint to None. Change needed for 2.2.1
as well.

Marc-André Lemburg 716cf91839 Moved the encoding map building logic from the individual mapping
codec files to codecs.py and added logic so that multi mappings
in the decoding maps now result in mappings to None (undefined mapping)
in the encoding maps.
2001-05-16 09:41:45 +00:00
Tim Peters 30324a7363 Just changed "x,y" to "x, y" everywhere (i.e., inserted horizontal space
after commas that didn't have any).
2001-05-15 17:19:16 +00:00
Skip Montanaro e99d5ea25b added __all__ lists to a number of Python modules
added test script and expected output file as well
this closes patch 103297.
__all__ attributes will be added to other modules without first submitting
a patch, just adding the necessary line to the test script to verify
more-or-less correct implementation.

Tim Peters 88869f9787 Whitespace normalization. 2001-01-14 23:36:06 +00:00
Marc-André Lemburg a866df806d This patch changes the default behaviour of the builtin charmap
codec to not apply Latin-1 mappings for keys which are not found
in the mapping dictionaries, but instead treat them as undefined
mappings.

The patch was originally written by Martin v. Loewis with some
additional (cosmetic) changes and an updated test script
by Marc-Andre Lemburg.

The standard codecs were recreated from the most current files
available at the Unicode.org site using the Tools/scripts/gencodec.py
tool.

This patch closes the bugs #116285 and #119960.

Fred Drake d254c0095c Remove redundent information from a docstring. 2000-10-02 22:11:47 +00:00
Thomas Wouters 7e47402264 Spelling fixes supplied by Rob W. W. Hooft. All these are fixes in either
comments, docstrings or error messages. I fixed two minor things in
test_winreg.py ("didn't" -> "Didn't" and "Didnt" -> "Didn't").

There is a minor style issue involved: Guido seems to have preferred English
grammar (behaviour, honour) in a couple places. This patch changes that to
American, which is the more prominent style in the source. I prefer English
myself, so if English is preferred, I'd be happy to supply a patch myself ;)

Guido van Rossum 1c89b0eeef Deleted trailing whitespace. This is really a way to be able to add
a missing part of the previous checkin message:

Marc-Andre Lemburg:

Added encoding name attributes to wrapper classes which
allow applications to check the used encoding names.

Guido van Rossum d8855fde88 Marc-Andre Lemburg:
Attached you find the latest update of the Unicode implementation.
The patch is against the current CVS version.

It includes the fix I posted yesterday for the core dump problem
in codecs.c (was introduced by my previous patch set -- sorry),
adds more tests for the codecs and two new parser markers
"es" and "es#".
