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.

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).

Make sure that writing an array instance returns the number of bytes,
...
not the number of array elements.

TextIO improvement:
...
- 25% speed increse in tell();
- f.seek(0, 1) now maps to f.seek(f.tell(), 0) instead of to f.tell().

Speed up next() by disabling snapshot updating then.

More efficient implementation of tell(); _read_chunk() doesn't have to
...
call self.buffer.tell().

Real pickling for bytes.
...
Restore complex pickling.
Use cPickle in io.py.

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.

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

Implement long positioning (Unix only, probably).
...
Etc., etc.

BufferedIOBase and TextIOBase should derive from IOBase, not from RawIOBase!
2007-04-10 14:41:39 +00:00

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
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
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
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

Get rid of duplicate definition of BufferedIOBase.

Added a working Text I/O layer, by Mark Russell.
...
This is essentially a checkpoint.

Check in Daniel Stutzbach's _fileio.c and test_fileio.py
...
(see SF#1671314) with small tweaks.
The io module now uses this instead of its own implementation
of the FileIO class, if it can import _fileio.

Change the specs for readinto() -- it should *not* shorten the buffer to
...
the amount of data read.

New version from Mike Verdone (sat in my inbox since 2/27).
...
I cleaned up whitespace but otherwise didn't change it.
This will need work to reflect the tentative decision to drop nonblocking I/O
support from the buffering layers.
2007-03-07 01:00:12 +00:00

Mike Verdone's checkpoint, cleaned up.
...
Also implemented Neal's suggestion (add fileno() to SocketIO)
and some unrelated changes, e.g. remove Google copyright
and make BytesIO a subclass of BufferedIOBase.
