Neal Norwitz 9b483f153a Remove ancient platforms: AIX 3 and Irix 5. (AIX 4 and Irix 6 remain.) 2007-04-17 08:19:58 +00:00
Guido van Rossum d76e7796c9 Instead of pickling the whole decoder, use the new getstate/setstate API. 2007-04-17 02:38:04 +00:00
Walter Dörwald 3abcb013b8 Apply SF patch #1698994: Add getstate() and setstate() 
methods to incrementalcodecs.

Also forward port r54786 (fix the incremental
utf_8_sig decoder).
 2007-04-16 22:10:50 +00:00
Guido van Rossum 8981ad05c0 Check in the inevitable change to the version number. 
I'll add this step to PEP 306.

Nick Coghlan 650f0d06d3 Hide list comp variables and support set comprehensions 2007-04-15 12:05:43 +00:00
Guido van Rossum 6ef6306dd6 Oops, don't test for a name attribute here. That's a higher-level feature. 2007-04-13 19:02:54 +00:00
Guido van Rossum 13633bb8c5 Support name and mode attributes on all file types. 
Don't read more than one line when reading text from a tty device.
Add peek() and read1() methods.
Return str instead of unicode when return ASCII characters in text mode.
 2007-04-13 18:42:35 +00:00
Guido van Rossum 913dd0be52 struct.unpack() allows a bytes string too (if it has the right size). 2007-04-13 03:33:53 +00:00
Guido van Rossum 98f9746740 Support marshal.dump(x, f) where f is not a real file. 
Support ord(b) where b is a 1-byte string.
In zipfile.py, work around bytes being ints instead of chars, sometimes.
 2007-04-13 03:31:13 +00:00
Guido van Rossum 84d79ddce2 Disallow u"..." + b"..." and b"..." + u"...". 2007-04-13 02:23:57 +00:00
Guido van Rossum ad7d8d10b7 Rough and dirty job -- allow concatenation of bytes and arbitrary 
buffer-supporting objects (Unicode always excluded), and also of
str and bytes.
(For some reason u"" + b"" doesn't fail, I'll investigate later.)
 2007-04-13 01:39:34 +00:00
Guido van Rossum dc0b1a1069 Make a few more tests pass with the new I/O library. 
Fix the truncate() semantics -- it should not affect the current position.
Switch wave.py/chunk.py to struct.unpack_from() to support bytes.
Don't use writelines() on binary files (test_fileinput.py).
 2007-04-12 22:55:07 +00:00
Guido van Rossum b6f1fdc90c Clean up trailing whitespace. 2007-04-12 22:49:52 +00:00
Guido van Rossum 682faf8fe0 Fix most XXX remarks. 2007-04-12 14:56:58 +00:00
Guido van Rossum 31c3a57480 Test closed, mode attribute; don't test __exit__(). 2007-04-12 14:51:49 +00:00
Guido van Rossum d410395ea7 Make sure that writing an array instance returns the number of bytes, 
not the number of array elements.
 2007-04-12 05:44:49 +00:00
Guido van Rossum aa43ed95cd TextIO improvement: 
- 25% speed increse in tell();
- f.seek(0, 1) now maps to f.seek(f.tell(), 0) instead of to f.tell().
 2007-04-12 05:24:24 +00:00
Georg Brandl 57b39e0916 Bug #1697782: remove all remaining code that uses types.InstanceType. 2007-04-11 19:24:50 +00:00
Guido van Rossum b5ddcfd2a2 Make array().tofile() work with a new I/O object. 2007-04-11 17:08:28 +00:00
Guido van Rossum d0712817ac Re-enable cleanup code. 2007-04-11 16:32:43 +00:00
Guido van Rossum b9c4c3e455 Speed up next() by disabling snapshot updating then. 2007-04-11 16:07:50 +00:00
Guido van Rossum cba608cadb More efficient implementation of tell(); _read_chunk() doesn't have to 
call self.buffer.tell().
 2007-04-11 14:19:59 +00:00
Guido van Rossum 0dd32e246c Real pickling for bytes. 
Restore complex pickling.
Use cPickle in io.py.
 2007-04-11 05:40:58 +00:00
Guido van Rossum 0ad0812edb An example of action-at-a-distance: fix the problems I had in test_io.py 
without touching io.py or test_io.py.  The cause of the failure was that
bytes objects didn't pickle right.  As a stop-gap measure, I'm providing
bytes pickling via copy_reg.  Eventually, we should use a more efficient
protocol, e.g. __reduce_ex__ or __getstate__/__setstate__.
 2007-04-11 04:37:43 +00:00
Guido van Rossum 9b76da6a8f Checkpoint so I can continue to work on this at a different box. 
There is somewhat working (but slow) code supporting seek/tell for text files,
but extensive testing exposes a bug I can't nail down.
 2007-04-11 01:09:03 +00:00
Guido van Rossum 8742977b33 truncate() returns the new size and position. 
write() returns the number of bytes/characters written/buffered.
FileIO.close() calls self.flush().
Implement readinto() for buffered readers.
Tests th check all these.
Test proper behavior of __enter__/__exit__.
 2007-04-10 21:06:59 +00:00
Guido van Rossum 34d69e57e3 Skip large file tests on Windowns and OSX. 
Reduce large file size to 2**31 (and a bit).
 2007-04-10 20:08:41 +00:00
Guido van Rossum 53807dabf0 Implement long positioning (Unix only, probably). 
Etc., etc.
 2007-04-10 19:01:47 +00:00
Guido van Rossum cce92b27d6 BufferedIOBase and TextIOBase should derive from IOBase, not from RawIOBase! 2007-04-10 14:41:39 +00:00
Guido van Rossum 141f767d46 More cleanup. Renamed BlockingIO to BlockingIOError. 
Removed unused _PyFileIO class.
Changed inheritance structure.
TODO: do the same kinds of things to TextIO.
 2007-04-10 00:22:16 +00:00
Guido van Rossum ebea9beab3 Bytes should never equal unicode. 
Add tests for str <cmpop> bytes.
 2007-04-09 00:49:13 +00:00
Guido van Rossum 343e97ff7f For Make Benefit Glorious Nation of Backwards Compatibility, 
bytes objects can now be compared to anything that supports the buffer API.
 2007-04-09 00:43:24 +00:00
Guido van Rossum 62cbc8a261 Make sure that a forked child process exits even if it raises an exception. 2007-04-09 00:41:25 +00:00
Guido van Rossum 933520b5ba Fix a place where it's pretty clear that a binary open mode was intended. 
(The new I/O library revealed the problem.)
 2007-04-09 00:00:23 +00:00
Guido van Rossum 4f0db6e4a1 Cleanup. 
Add closed attribute.
Support int argument to open() -- wrapping a file descriptor.
For b/w compat, support readline(n).
Support readlines() and readlines(n).
Flush on __del__.
Added some XXX comments.
 2007-04-08 23:59:06 +00:00
Guido van Rossum b04281592e Make it possible to instantiate a _FileIO() with an integer file descriptor 
instead of a filename.
Add a 'closed' attribute.
 2007-04-08 17:44:42 +00:00
Guido van Rossum b8551ae68f Somehow this contained a bogus reference to "exceptions" which caused 
"import exceptions" to behave bizarrely.
 2007-04-07 03:14:46 +00:00
Guido van Rossum 756aa93763 A class used as an exception should inherit from Exception. 
(Should be backported to 2.6, really.)
 2007-04-07 03:04:01 +00:00
Guido van Rossum 9be5597abf Add some backwards compatibility stuff. 
This now appears to work when io.open is substituted for the real open
in fileinput.py -- at least the latter's unit tests pass.
 2007-04-07 02:59:27 +00:00
Guido van Rossum 76c5d4d72d Checkpoint. 
Some cleanup of test_io.py and io.py.
Added seeking to buffered reader and writer, but no tests yet.
 2007-04-06 19:10:29 +00:00
Guido van Rossum 186685905c Get rid of duplicate definition of BufferedIOBase. 2007-04-06 18:11:47 +00:00
Guido van Rossum 78892e4613 Added a working Text I/O layer, by Mark Russell. 
This is essentially a checkpoint.
 2007-04-06 17:31:18 +00:00
Fred Drake 0e074483e7 make the markup match that of the trunk to avoid insane spread of 
mystery italics
 2007-03-29 23:11:24 +00:00
Guido van Rossum 6b18a5bb32 Fix refcounting bug reported by Amaury Forgeot d'Arc. 2007-03-29 20:49:57 +00:00
Collin Winter 42dae6a89b Make readonly members defined in C throw an AttributeError on modification. This brings them into sync with Python-level attributes. Fixes bug #1687163. 2007-03-28 21:44:53 +00:00
Guido van Rossum d84da1b67a More fixes related to removal of exception slicing. 2007-03-28 21:03:48 +00:00
Guido van Rossum 782ff275b8 Fix errors in bsddb3 tests due to removal of exception slicing. 
(There was also a segfault but it disappeared when the tests
stopped erroring out; I presume the segfault is a pre-existing
problem somewhere in a destructor.)
 2007-03-28 21:02:43 +00:00
Guido van Rossum cef2098cfa Moving xreload to the sandbox for now. 2007-03-28 00:30:15 +00:00
Guido van Rossum e27dc72308 By default, != returns the opposite of ==, unless the latter returns 
NotImplemented.

(Is this worth backporting to 2.6?  It seems so useful...!)
 2007-03-27 22:37:34 +00:00
Guido van Rossum a4335b1e6b Looks like this file wasn't checked in. 2007-03-27 22:34:34 +00:00
