merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc. I was slightly helpful at the end. :) Following are the log messages from the io-c branch: Merged revisions 68683-68685,68687-68689,68693,68704,68741-68743,68745,68747,68752-68754,68756,68758,68812,68816-68817,68820-68822,68824-68825,68828,68876-68877,69037,69044,69104,69115,69194,69626-69629,69636,69638,69641-69642,69644-69654,69656-69661,69671,69677,69812-69815,69817,69827-69830,69839,69841-69845,69848,69850,69852,69854,69860,69865-69866,69868,69872-69873,69885,69888,69891-69893,69911,69913-69916,69963,70033,70035,70038,70041-70048,70067-70070,70075,70112,70133,70135,70140 via svnmerge from svn+ssh://pythondev@svn.python.org/python/branches/io-c ........ r68683 | antoine.pitrou | 2009-01-17 17:13:48 -0600 (Sat, 17 Jan 2009) | 3 lines Merge in changes from the io-c sandbox.

merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc. I was slightly helpful at the end. :) Following are the log messages from the io-c branch: Merged revisions 68683-68685,68687-68689,68693,68704,68741-68743,68745,68747,68752-68754,68756,68758,68812,68816-68817,68820-68822,68824-68825,68828,68876-68877,69037,69044,69104,69115,69194,69626-69629,69636,69638,69641-69642,69644-69654,69656-69661,69671,69677,69812-69815,69817,69827-69830,69839,69841-69845,69848,69850,69852,69854,69860,69865-69866,69868,69872-69873,69885,69888,69891-69893,69911,69913-69916,69963,70033,70035,70038,70041-70048,70067-70070,70075,70112,70133,70135,70140 via svnmerge from svn+ssh://pythondev@svn.python.org/python/branches/io-c ........ r68683 | antoine.pitrou | 2009-01-17 17:13:48 -0600 (Sat, 17 Jan 2009) | 3 lines Merge in changes from the io-c sandbox.

merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc. I was slightly helpful at the end. :) Following are the log messages from the io-c branch: Merged revisions 68683-68685,68687-68689,68693,68704,68741-68743,68745,68747,68752-68754,68756,68758,68812,68816-68817,68820-68822,68824-68825,68828,68876-68877,69037,69044,69104,69115,69194,69626-69629,69636,69638,69641-69642,69644-69654,69656-69661,69671,69677,69812-69815,69817,69827-69830,69839,69841-69845,69848,69850,69852,69854,69860,69865-69866,69868,69872-69873,69885,69888,69891-69893,69911,69913-69916,69963,70033,70035,70038,70041-70048,70067-70070,70075,70112,70133,70135,70140 via svnmerge from svn+ssh://pythondev@svn.python.org/python/branches/io-c ........ r68683 | antoine.pitrou | 2009-01-17 17:13:48 -0600 (Sat, 17 Jan 2009) | 3 lines Merge in changes from the io-c sandbox.

merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc. I was slightly helpful at the end. :) Following are the log messages from the io-c branch: Merged revisions 68683-68685,68687-68689,68693,68704,68741-68743,68745,68747,68752-68754,68756,68758,68812,68816-68817,68820-68822,68824-68825,68828,68876-68877,69037,69044,69104,69115,69194,69626-69629,69636,69638,69641-69642,69644-69654,69656-69661,69671,69677,69812-69815,69817,69827-69830,69839,69841-69845,69848,69850,69852,69854,69860,69865-69866,69868,69872-69873,69885,69888,69891-69893,69911,69913-69916,69963,70033,70035,70038,70041-70048,70067-70070,70075,70112,70133,70135,70140 via svnmerge from svn+ssh://pythondev@svn.python.org/python/branches/io-c ........ r68683 | antoine.pitrou | 2009-01-17 17:13:48 -0600 (Sat, 17 Jan 2009) | 3 lines Merge in changes from the io-c sandbox.

r"""Open file and return a stream. Raise IOError upon failure.
file is either a text or byte string giving the name (and the path
if the file isn't in the current working directory) of the file to
be opened or an integer file descriptor of the file to be
wrapped. (If a file descriptor is given, it is closed when the
returned I/O object is closed, unless closefd is set to False.)
mode is an optional string that specifies the mode in which the file
is opened. It defaults to 'r' which means open for reading in text
mode. Other common values are 'w' for writing (truncating the file if
it already exists), and 'a' for appending (which on some Unix systems,
means that all writes append to the end of the file regardless of the
current seek position). In text mode, if encoding is not specified the
encoding used is platform dependent. (For reading and writing raw
bytes use binary mode and leave encoding unspecified.) The available
modes are:
========= ===============================================================
Character Meaning
--------- ---------------------------------------------------------------
'r' open for reading (default)
'w' open for writing, truncating the file first
'a' open for writing, appending to the end of the file if it exists
'b' binary mode
't' text mode (default)
'+' open a disk file for updating (reading and writing)
'U' universal newline mode (for backwards compatibility; unneeded
for new code)
========= ===============================================================
The default mode is 'rt' (open for reading text). For binary random
access, the mode 'w+b' opens and truncates the file to 0 bytes, while
'r+b' opens the file without truncation.
Python distinguishes between files opened in binary and text modes,
even when the underlying operating system doesn't. Files opened in
binary mode (appending 'b' to the mode argument) return contents as
bytes objects without any decoding. In text mode (the default, or when
't' is appended to the mode argument), the contents of the file are
returned as strings, the bytes having been first decoded using a
platform-dependent encoding or using the specified encoding if given.
buffering is an optional integer used to set the buffering policy.
Pass 0 to switch buffering off (only allowed in binary mode), 1 to select
line buffering (only usable in text mode), and an integer > 1 to indicate
the size of a fixed-size chunk buffer. When no buffering argument is
given, the default buffering policy works as follows:
* Binary files are buffered in fixed-size chunks; the size of the buffer
is chosen using a heuristic trying to determine the underlying device's
"block size" and falling back on `io.DEFAULT_BUFFER_SIZE`.
On many systems, the buffer will typically be 4096 or 8192 bytes long.
* "Interactive" text files (files for which isatty() returns True)
use line buffering. Other text files use the policy described above
for binary files.
merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc. I was slightly helpful at the end. :) Following are the log messages from the io-c branch: Merged revisions 68683-68685,68687-68689,68693,68704,68741-68743,68745,68747,68752-68754,68756,68758,68812,68816-68817,68820-68822,68824-68825,68828,68876-68877,69037,69044,69104,69115,69194,69626-69629,69636,69638,69641-69642,69644-69654,69656-69661,69671,69677,69812-69815,69817,69827-69830,69839,69841-69845,69848,69850,69852,69854,69860,69865-69866,69868,69872-69873,69885,69888,69891-69893,69911,69913-69916,69963,70033,70035,70038,70041-70048,70067-70070,70075,70112,70133,70135,70140 via svnmerge from svn+ssh://pythondev@svn.python.org/python/branches/io-c ........ r68683 | antoine.pitrou | 2009-01-17 17:13:48 -0600 (Sat, 17 Jan 2009) | 3 lines Merge in changes from the io-c sandbox.

encoding is the name of the encoding used to decode or encode the
file. This should only be used in text mode. The default encoding is
platform dependent, but any encoding supported by Python can be
passed. See the codecs module for the list of supported encodings.
errors is an optional string that specifies how encoding errors are to
be handled---this argument should not be used in binary mode. Pass
'strict' to raise a ValueError exception if there is an encoding error
(the default of None has the same effect), or pass 'ignore' to ignore
errors. (Note that ignoring encoding errors can lead to data loss.)
See the documentation for codecs.register for a list of the permitted
encoding error strings.
newline controls how universal newlines works (it only applies to text
mode). It can be None, '', '\n', '\r', and '\r\n'. It works as
follows:
* On input, if newline is None, universal newlines mode is
enabled. Lines in the input can end in '\n', '\r', or '\r\n', and
these are translated into '\n' before being returned to the
caller. If it is '', universal newline mode is enabled, but line
endings are returned to the caller untranslated. If it has any of
the other legal values, input lines are only terminated by the given
string, and the line ending is returned to the caller untranslated.
* On output, if newline is None, any '\n' characters written are
translated to the system default line separator, os.linesep. If
newline is '', no translation takes place. If newline is any of the
other legal values, any '\n' characters written are translated to
the given string.
If closefd is False, the underlying file descriptor will be kept open
when the file is closed. This does not work when a file name is given
and must be True in that case.
open() returns a file object whose type depends on the mode, and
through which the standard file operations such as reading and writing
are performed. When open() is used to open a file in a text mode ('w',
'r', 'wt', 'rt', etc.), it returns a TextIOWrapper. When used to open
a file in a binary mode, the returned class varies: in read binary
mode, it returns a BufferedReader; in write binary and append binary
modes, it returns a BufferedWriter, and in read/write mode, it returns
a BufferedRandom.
It is also possible to use a string or bytearray as a file for both
reading and writing. For strings StringIO can be used like a file
opened in a text mode, and for bytes a BytesIO can be used like a file
opened in a binary mode.

Even though IOBase does not declare read, readinto, or write because
their signatures will vary, implementations and clients should
consider those methods part of the interface. Also, implementations
may raise a IOError when operations they do not support are called.
The basic type used for binary data read from or written to a file is
bytes. bytearrays are accepted too, and in some cases (such as
readinto) needed. Text I/O classes work with str data.
Note that calling any method (even inquiries) on a closed stream is
undefined. Implementations may raise IOError in this case.
IOBase (and its subclasses) support the iterator protocol, meaning
that an IOBase object can be iterated over yielding the lines in a
stream.
IOBase also supports the :keyword:`with` statement. In this example,
fp is closed after the suite of the with statement is complete:
with open('spam.txt', 'r') as fp:

merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc.

merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc. I was slightly helpful at the end. :) Following are the log messages from the io-c branch: Merged revisions 68683-68685,68687-68689,68693,68704,68741-68743,68745,68747,68752-68754,68756,68758,68812,68816-68817,68820-68822,68824-68825,68828,68876-68877,69037,69044,69104,69115,69194,69626-69629,69636,69638,69641-69642,69644-69654,69656-69661,69671,69677,69812-69815,69817,69827-69830,69839,69841-69845,69848,69850,69852,69854,69860,69865-69866,69868,69872-69873,69885,69888,69891-69893,69911,69913-69916,69963,70033,70035,70038,70041-70048,70067-70070,70075,70112,70133,70135,70140 via svnmerge from svn+ssh://pythondev@svn.python.org/python/branches/io-c ........ r68683 | antoine.pitrou | 2009-01-17 17:13:48 -0600 (Sat, 17 Jan 2009) | 3 lines Merge in changes from the io-c sandbox.

merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc. I was slightly helpful at the end. :) Following are the log messages from the io-c branch: Merged revisions 68683-68685,68687-68689,68693,68704,68741-68743,68745,68747,68752-68754,68756,68758,68812,68816-68817,68820-68822,68824-68825,68828,68876-68877,69037,69044,69104,69115,69194,69626-69629,69636,69638,69641-69642,69644-69654,69656-69661,69671,69677,69812-69815,69817,69827-69830,69839,69841-69845,69848,69850,69852,69854,69860,69865-69866,69868,69872-69873,69885,69888,69891-69893,69911,69913-69916,69963,70033,70035,70038,70041-70048,70067-70070,70075,70112,70133,70135,70140 via svnmerge from svn+ssh://pythondev@svn.python.org/python/branches/io-c ........ r68683 | antoine.pitrou | 2009-01-17 17:13:48 -0600 (Sat, 17 Jan 2009) | 3 lines Merge in changes from the io-c sandbox.

merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc. I was slightly helpful at the end. :) Following are the log messages from the io-c branch: Merged revisions 68683-68685,68687-68689,68693,68704,68741-68743,68745,68747,68752-68754,68756,68758,68812,68816-68817,68820-68822,68824-68825,68828,68876-68877,69037,69044,69104,69115,69194,69626-69629,69636,69638,69641-69642,69644-69654,69656-69661,69671,69677,69812-69815,69817,69827-69830,69839,69841-69845,69848,69850,69852,69854,69860,69865-69866,69868,69872-69873,69885,69888,69891-69893,69911,69913-69916,69963,70033,70035,70038,70041-70048,70067-70070,70075,70112,70133,70135,70140 via svnmerge from svn+ssh://pythondev@svn.python.org/python/branches/io-c ........ r68683 | antoine.pitrou | 2009-01-17 17:13:48 -0600 (Sat, 17 Jan 2009) | 3 lines Merge in changes from the io-c sandbox.

merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc. I was slightly helpful at the end. :) Following are the log messages from the io-c branch: Merged revisions 68683-68685,68687-68689,68693,68704,68741-68743,68745,68747,68752-68754,68756,68758,68812,68816-68817,68820-68822,68824-68825,68828,68876-68877,69037,69044,69104,69115,69194,69626-69629,69636,69638,69641-69642,69644-69654,69656-69661,69671,69677,69812-69815,69817,69827-69830,69839,69841-69845,69848,69850,69852,69854,69860,69865-69866,69868,69872-69873,69885,69888,69891-69893,69911,69913-69916,69963,70033,70035,70038,70041-70048,70067-70070,70075,70112,70133,70135,70140 via svnmerge from svn+ssh://pythondev@svn.python.org/python/branches/io-c ........ r68683 | antoine.pitrou | 2009-01-17 17:13:48 -0600 (Sat, 17 Jan 2009) | 3 lines Merge in changes from the io-c sandbox.

merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc.

merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc. I was slightly helpful at the end. :) Following are the log messages from the io-c branch: Merged revisions 68683-68685,68687-68689,68693,68704,68741-68743,68745,68747,68752-68754,68756,68758,68812,68816-68817,68820-68822,68824-68825,68828,68876-68877,69037,69044,69104,69115,69194,69626-69629,69636,69638,69641-69642,69644-69654,69656-69661,69671,69677,69812-69815,69817,69827-69830,69839,69841-69845,69848,69850,69852,69854,69860,69865-69866,69868,69872-69873,69885,69888,69891-69893,69911,69913-69916,69963,70033,70035,70038,70041-70048,70067-70070,70075,70112,70133,70135,70140 via svnmerge from svn+ssh://pythondev@svn.python.org/python/branches/io-c ........ r68683 | antoine.pitrou | 2009-01-17 17:13:48 -0600 (Sat, 17 Jan 2009) | 3 lines Merge in changes from the io-c sandbox.

merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc. I was slightly helpful at the end. :) Following are the log messages from the io-c branch: Merged revisions 68683-68685,68687-68689,68693,68704,68741-68743,68745,68747,68752-68754,68756,68758,68812,68816-68817,68820-68822,68824-68825,68828,68876-68877,69037,69044,69104,69115,69194,69626-69629,69636,69638,69641-69642,69644-69654,69656-69661,69671,69677,69812-69815,69817,69827-69830,69839,69841-69845,69848,69850,69852,69854,69860,69865-69866,69868,69872-69873,69885,69888,69891-69893,69911,69913-69916,69963,70033,70035,70038,70041-70048,70067-70070,70075,70112,70133,70135,70140 via svnmerge from svn+ssh://pythondev@svn.python.org/python/branches/io-c ........ r68683 | antoine.pitrou | 2009-01-17 17:13:48 -0600 (Sat, 17 Jan 2009) | 3 lines Merge in changes from the io-c sandbox.

merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc. I was slightly helpful at the end. :) Following are the log messages from the io-c branch: Merged revisions 68683-68685,68687-68689,68693,68704,68741-68743,68745,68747,68752-68754,68756,68758,68812,68816-68817,68820-68822,68824-68825,68828,68876-68877,69037,69044,69104,69115,69194,69626-69629,69636,69638,69641-69642,69644-69654,69656-69661,69671,69677,69812-69815,69817,69827-69830,69839,69841-69845,69848,69850,69852,69854,69860,69865-69866,69868,69872-69873,69885,69888,69891-69893,69911,69913-69916,69963,70033,70035,70038,70041-70048,70067-70070,70075,70112,70133,70135,70140 via svnmerge from svn+ssh://pythondev@svn.python.org/python/branches/io-c ........ r68683 | antoine.pitrou | 2009-01-17 17:13:48 -0600 (Sat, 17 Jan 2009) | 3 lines Merge in changes from the io-c sandbox.

merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc. I was slightly helpful at the end. :) Following are the log messages from the io-c branch: Merged revisions 68683-68685,68687-68689,68693,68704,68741-68743,68745,68747,68752-68754,68756,68758,68812,68816-68817,68820-68822,68824-68825,68828,68876-68877,69037,69044,69104,69115,69194,69626-69629,69636,69638,69641-69642,69644-69654,69656-69661,69671,69677,69812-69815,69817,69827-69830,69839,69841-69845,69848,69850,69852,69854,69860,69865-69866,69868,69872-69873,69885,69888,69891-69893,69911,69913-69916,69963,70033,70035,70038,70041-70048,70067-70070,70075,70112,70133,70135,70140 via svnmerge from svn+ssh://pythondev@svn.python.org/python/branches/io-c ........ r68683 | antoine.pitrou | 2009-01-17 17:13:48 -0600 (Sat, 17 Jan 2009) | 3 lines Merge in changes from the io-c sandbox.

merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc. I was slightly helpful at the end. :) Following are the log messages from the io-c branch: Merged revisions 68683-68685,68687-68689,68693,68704,68741-68743,68745,68747,68752-68754,68756,68758,68812,68816-68817,68820-68822,68824-68825,68828,68876-68877,69037,69044,69104,69115,69194,69626-69629,69636,69638,69641-69642,69644-69654,69656-69661,69671,69677,69812-69815,69817,69827-69830,69839,69841-69845,69848,69850,69852,69854,69860,69865-69866,69868,69872-69873,69885,69888,69891-69893,69911,69913-69916,69963,70033,70035,70038,70041-70048,70067-70070,70075,70112,70133,70135,70140 via svnmerge from svn+ssh://pythondev@svn.python.org/python/branches/io-c ........ r68683 | antoine.pitrou | 2009-01-17 17:13:48 -0600 (Sat, 17 Jan 2009) | 3 lines Merge in changes from the io-c sandbox.

"""A buffered reader and writer object together.
A buffered reader object and buffered writer object put together to
form a sequential IO object that can read and write. This is typically
used with a socket or two-way pipe.
reader and writer are RawIOBase objects that are readable and
writeable respectively. If the buffer_size is omitted it defaults to

merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc. I was slightly helpful at the end. :) Following are the log messages from the io-c branch: Merged revisions 68683-68685,68687-68689,68693,68704,68741-68743,68745,68747,68752-68754,68756,68758,68812,68816-68817,68820-68822,68824-68825,68828,68876-68877,69037,69044,69104,69115,69194,69626-69629,69636,69638,69641-69642,69644-69654,69656-69661,69671,69677,69812-69815,69817,69827-69830,69839,69841-69845,69848,69850,69852,69854,69860,69865-69866,69868,69872-69873,69885,69888,69891-69893,69911,69913-69916,69963,70033,70035,70038,70041-70048,70067-70070,70075,70112,70133,70135,70140 via svnmerge from svn+ssh://pythondev@svn.python.org/python/branches/io-c ........ r68683 | antoine.pitrou | 2009-01-17 17:13:48 -0600 (Sat, 17 Jan 2009) | 3 lines Merge in changes from the io-c sandbox.

merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc. I was slightly helpful at the end. :) Following are the log messages from the io-c branch: Merged revisions 68683-68685,68687-68689,68693,68704,68741-68743,68745,68747,68752-68754,68756,68758,68812,68816-68817,68820-68822,68824-68825,68828,68876-68877,69037,69044,69104,69115,69194,69626-69629,69636,69638,69641-69642,69644-69654,69656-69661,69671,69677,69812-69815,69817,69827-69830,69839,69841-69845,69848,69850,69852,69854,69860,69865-69866,69868,69872-69873,69885,69888,69891-69893,69911,69913-69916,69963,70033,70035,70038,70041-70048,70067-70070,70075,70112,70133,70135,70140 via svnmerge from svn+ssh://pythondev@svn.python.org/python/branches/io-c ........ r68683 | antoine.pitrou | 2009-01-17 17:13:48 -0600 (Sat, 17 Jan 2009) | 3 lines Merge in changes from the io-c sandbox.

merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc. I was slightly helpful at the end. :) Following are the log messages from the io-c branch: Merged revisions 68683-68685,68687-68689,68693,68704,68741-68743,68745,68747,68752-68754,68756,68758,68812,68816-68817,68820-68822,68824-68825,68828,68876-68877,69037,69044,69104,69115,69194,69626-69629,69636,69638,69641-69642,69644-69654,69656-69661,69671,69677,69812-69815,69817,69827-69830,69839,69841-69845,69848,69850,69852,69854,69860,69865-69866,69868,69872-69873,69885,69888,69891-69893,69911,69913-69916,69963,70033,70035,70038,70041-70048,70067-70070,70075,70112,70133,70135,70140 via svnmerge from svn+ssh://pythondev@svn.python.org/python/branches/io-c ........ r68683 | antoine.pitrou | 2009-01-17 17:13:48 -0600 (Sat, 17 Jan 2009) | 3 lines Merge in changes from the io-c sandbox.

merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc. I was slightly helpful at the end. :) Following are the log messages from the io-c branch: Merged revisions 68683-68685,68687-68689,68693,68704,68741-68743,68745,68747,68752-68754,68756,68758,68812,68816-68817,68820-68822,68824-68825,68828,68876-68877,69037,69044,69104,69115,69194,69626-69629,69636,69638,69641-69642,69644-69654,69656-69661,69671,69677,69812-69815,69817,69827-69830,69839,69841-69845,69848,69850,69852,69854,69860,69865-69866,69868,69872-69873,69885,69888,69891-69893,69911,69913-69916,69963,70033,70035,70038,70041-70048,70067-70070,70075,70112,70133,70135,70140 via svnmerge from svn+ssh://pythondev@svn.python.org/python/branches/io-c ........ r68683 | antoine.pitrou | 2009-01-17 17:13:48 -0600 (Sat, 17 Jan 2009) | 3 lines Merge in changes from the io-c sandbox.

merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc. I was slightly helpful at the end. :) Following are the log messages from the io-c branch: Merged revisions 68683-68685,68687-68689,68693,68704,68741-68743,68745,68747,68752-68754,68756,68758,68812,68816-68817,68820-68822,68824-68825,68828,68876-68877,69037,69044,69104,69115,69194,69626-69629,69636,69638,69641-69642,69644-69654,69656-69661,69671,69677,69812-69815,69817,69827-69830,69839,69841-69845,69848,69850,69852,69854,69860,69865-69866,69868,69872-69873,69885,69888,69891-69893,69911,69913-69916,69963,70033,70035,70038,70041-70048,70067-70070,70075,70112,70133,70135,70140 via svnmerge from svn+ssh://pythondev@svn.python.org/python/branches/io-c ........ r68683 | antoine.pitrou | 2009-01-17 17:13:48 -0600 (Sat, 17 Jan 2009) | 3 lines Merge in changes from the io-c sandbox.

merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc.

merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc. I was slightly helpful at the end. :) Following are the log messages from the io-c branch: Merged revisions 68683-68685,68687-68689,68693,68704,68741-68743,68745,68747,68752-68754,68756,68758,68812,68816-68817,68820-68822,68824-68825,68828,68876-68877,69037,69044,69104,69115,69194,69626-69629,69636,69638,69641-69642,69644-69654,69656-69661,69671,69677,69812-69815,69817,69827-69830,69839,69841-69845,69848,69850,69852,69854,69860,69865-69866,69868,69872-69873,69885,69888,69891-69893,69911,69913-69916,69963,70033,70035,70038,70041-70048,70067-70070,70075,70112,70133,70135,70140 via svnmerge from svn+ssh://pythondev@svn.python.org/python/branches/io-c ........ r68683 | antoine.pitrou | 2009-01-17 17:13:48 -0600 (Sat, 17 Jan 2009) | 3 lines Merge in changes from the io-c sandbox.

encoding gives the name of the encoding that the stream will be
decoded or encoded with. It defaults to locale.getpreferredencoding.
errors determines the strictness of encoding and decoding (see the
codecs.register) and defaults to "strict".
newline can be None, '', '\n', '\r', or '\r\n'. It controls the
handling of line endings. If it is None, universal newlines is
enabled. With this enabled, on input, the lines endings '\n', '\r',
or '\r\n' are translated to '\n' before being returned to the
caller. Conversely, on output, '\n' is translated to the system
default line seperator, os.linesep. If newline is any other of its
legal values, that newline becomes the newline when the file is read
and it is returned untranslated. On output, '\n' is converted to the
newline.
If line_buffering is True, a call to flush is implied when a call to
write contains a newline character.

merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc. I was slightly helpful at the end. :) Following are the log messages from the io-c branch: Merged revisions 68683-68685,68687-68689,68693,68704,68741-68743,68745,68747,68752-68754,68756,68758,68812,68816-68817,68820-68822,68824-68825,68828,68876-68877,69037,69044,69104,69115,69194,69626-69629,69636,69638,69641-69642,69644-69654,69656-69661,69671,69677,69812-69815,69817,69827-69830,69839,69841-69845,69848,69850,69852,69854,69860,69865-69866,69868,69872-69873,69885,69888,69891-69893,69911,69913-69916,69963,70033,70035,70038,70041-70048,70067-70070,70075,70112,70133,70135,70140 via svnmerge from svn+ssh://pythondev@svn.python.org/python/branches/io-c ........ r68683 | antoine.pitrou | 2009-01-17 17:13:48 -0600 (Sat, 17 Jan 2009) | 3 lines Merge in changes from the io-c sandbox.

merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc. I was slightly helpful at the end. :) Following are the log messages from the io-c branch: Merged revisions 68683-68685,68687-68689,68693,68704,68741-68743,68745,68747,68752-68754,68756,68758,68812,68816-68817,68820-68822,68824-68825,68828,68876-68877,69037,69044,69104,69115,69194,69626-69629,69636,69638,69641-69642,69644-69654,69656-69661,69671,69677,69812-69815,69817,69827-69830,69839,69841-69845,69848,69850,69852,69854,69860,69865-69866,69868,69872-69873,69885,69888,69891-69893,69911,69913-69916,69963,70033,70035,70038,70041-70048,70067-70070,70075,70112,70133,70135,70140 via svnmerge from svn+ssh://pythondev@svn.python.org/python/branches/io-c ........ r68683 | antoine.pitrou | 2009-01-17 17:13:48 -0600 (Sat, 17 Jan 2009) | 3 lines Merge in changes from the io-c sandbox.

merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc. I was slightly helpful at the end. :) Following are the log messages from the io-c branch: Merged revisions 68683-68685,68687-68689,68693,68704,68741-68743,68745,68747,68752-68754,68756,68758,68812,68816-68817,68820-68822,68824-68825,68828,68876-68877,69037,69044,69104,69115,69194,69626-69629,69636,69638,69641-69642,69644-69654,69656-69661,69671,69677,69812-69815,69817,69827-69830,69839,69841-69845,69848,69850,69852,69854,69860,69865-69866,69868,69872-69873,69885,69888,69891-69893,69911,69913-69916,69963,70033,70035,70038,70041-70048,70067-70070,70075,70112,70133,70135,70140 via svnmerge from svn+ssh://pythondev@svn.python.org/python/branches/io-c ........ r68683 | antoine.pitrou | 2009-01-17 17:13:48 -0600 (Sat, 17 Jan 2009) | 3 lines Merge in changes from the io-c sandbox.

merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc.

merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc. I was slightly helpful at the end. :) Following are the log messages from the io-c branch: Merged revisions 68683-68685,68687-68689,68693,68704,68741-68743,68745,68747,68752-68754,68756,68758,68812,68816-68817,68820-68822,68824-68825,68828,68876-68877,69037,69044,69104,69115,69194,69626-69629,69636,69638,69641-69642,69644-69654,69656-69661,69671,69677,69812-69815,69817,69827-69830,69839,69841-69845,69848,69850,69852,69854,69860,69865-69866,69868,69872-69873,69885,69888,69891-69893,69911,69913-69916,69963,70033,70035,70038,70041-70048,70067-70070,70075,70112,70133,70135,70140 via svnmerge from svn+ssh://pythondev@svn.python.org/python/branches/io-c ........ r68683 | antoine.pitrou | 2009-01-17 17:13:48 -0600 (Sat, 17 Jan 2009) | 3 lines Merge in changes from the io-c sandbox.

The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc. I was slightly helpful at the end. :) Following are the log messages from the io-c branch: Merged revisions 68683-68685,68687-68689,68693,68704,68741-68743,68745,68747,68752-68754,68756,68758,68812,68816-68817,68820-68822,68824-68825,68828,68876-68877,69037,69044,69104,69115,69194,69626-69629,69636,69638,69641-69642,69644-69654,69656-69661,69671,69677,69812-69815,69817,69827-69830,69839,69841-69845,69848,69850,69852,69854,69860,69865-69866,69868,69872-69873,69885,69888,69891-69893,69911,69913-69916,69963,70033,70035,70038,70041-70048,70067-70070,70075,70112,70133,70135,70140 via svnmerge from svn+ssh://pythondev@svn.python.org/python/branches/io-c ........ r68683 | antoine.pitrou | 2009-01-17 17:13:48 -0600 (Sat, 17 Jan 2009) | 3 lines Merge in changes from the io-c sandbox.

merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc. I was slightly helpful at the end. :) Following are the log messages from the io-c branch: Merged revisions 68683-68685,68687-68689,68693,68704,68741-68743,68745,68747,68752-68754,68756,68758,68812,68816-68817,68820-68822,68824-68825,68828,68876-68877,69037,69044,69104,69115,69194,69626-69629,69636,69638,69641-69642,69644-69654,69656-69661,69671,69677,69812-69815,69817,69827-69830,69839,69841-69845,69848,69850,69852,69854,69860,69865-69866,69868,69872-69873,69885,69888,69891-69893,69911,69913-69916,69963,70033,70035,70038,70041-70048,70067-70070,70075,70112,70133,70135,70140 via svnmerge from svn+ssh://pythondev@svn.python.org/python/branches/io-c ........ r68683 | antoine.pitrou | 2009-01-17 17:13:48 -0600 (Sat, 17 Jan 2009) | 3 lines Merge in changes from the io-c sandbox.

merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc. I was slightly helpful at the end. :) Following are the log messages from the io-c branch: Merged revisions 68683-68685,68687-68689,68693,68704,68741-68743,68745,68747,68752-68754,68756,68758,68812,68816-68817,68820-68822,68824-68825,68828,68876-68877,69037,69044,69104,69115,69194,69626-69629,69636,69638,69641-69642,69644-69654,69656-69661,69671,69677,69812-69815,69817,69827-69830,69839,69841-69845,69848,69850,69852,69854,69860,69865-69866,69868,69872-69873,69885,69888,69891-69893,69911,69913-69916,69963,70033,70035,70038,70041-70048,70067-70070,70075,70112,70133,70135,70140 via svnmerge from svn+ssh://pythondev@svn.python.org/python/branches/io-c ........ r68683 | antoine.pitrou | 2009-01-17 17:13:48 -0600 (Sat, 17 Jan 2009) | 3 lines Merge in changes from the io-c sandbox.

merge the io-c branch: C implementation of the io module The main io module now uses the C implementation. The Python one still exists in Lib/_pyio.py for ease of testing new features and usefulness to other implementers. The rewrite was done by Antoine Pitrou and Amaury Forgeot d'Arc.
