Jeremy Hylton e298c3018c if the GzipFile constructor fails, the __del__ method is still
called.  catch the resulting AttributeError and exit cleanly.

Guido van Rossum 4b8c6eaf8b Actually, the previous batch's comment should have been different;
*this* set of patches is Ka-Ping's final sweep:

The attached patches update the standard library so that all modules
have docstrings beginning with one-line summaries.

A new docstring was added to formatter.  The docstring for os.py
was updated to mention nt, os2, ce in addition to posix, dos, mac.

Guido van Rossum 54f22ed30b More trivial comment -> docstring transformations by Ka-Ping Yee,
who writes:

Here is batch 2, as a big collection of CVS context diffs.
Along with moving comments into docstrings, i've added a
couple of missing docstrings and attempted to make sure more
module docstrings begin with a one-line summary.

I did not add docstrings to the methods in profile.py for
fear of upsetting any careful optimizations there, though
i did move class documentation into class docstrings.

The convention i'm using is to leave credits/version/copyright
type of stuff in # comments, and move the rest of the descriptive
stuff about module usage into module docstrings.  Hope this is
okay.

Guido van Rossum 5606801b64 Make read() and readlines() conform more to the file object interface:
the default arg for read() is -1, not None, and readlines() has an
optional argument (which for now is ignored).

Andrew M. Kuchling 2d813e5140 Fixed 'return EOFError' that should be 'raise EOFError', caught by
Skip Montanaro's return-value patches.

Andrew M. Kuchling 916fcc3b18 Added __del__ method to GzipFile class that will flush and close the
object, if required.

Guido van Rossum 95bdd0b604 Two different changes.
1. Jack Jansen reports that on the Mac, the time may be negative, and
solves this by adding a write32u() function that writes an unsigned
long.

2. On 64-bit platforms the CRC comparison fails; I've fixed this by
casting both values to be compared to "unsigned long" i.e. modulo
0x100000000L.

Fred Drake fa1591c129 Oops, missed mode parameter to open(). 1999-04-05 18:37:59 +00:00
Fred Drake 9bb76d1b73 Made the default mode 'rb' instead of 'r', for better cross-platform
support.  (Based on comment on the documentation by Bernhard Reiter
<bernhard@csd.uwm.edu>).

Andrew M. Kuchling f4f119c055 Based on a suggestion from bruce@hams.com, make a trivial change to
allow using the 'a' flag as a mode for opening a GzipFile.  gzip
files, surprisingly enough, can be concatenated and then decompressed;
the effect is to concatenate the two chunks of data.

If we support it on writing, it should also be supported on reading.
This *wasn't* trivial, and required rearranging the code in the
reading path, particularly the _read() method.

Raise IOError instead of RuntimeError in two cases, 'Not a gzipped file'
and 'Unknown compression method'

Jeremy Hylton c19f9972a1 use struct instead of bit-manipulate in Python 1999-03-23 23:05:34 +00:00
Guido van Rossum 84c6fc9653 Patch by Ron Klatchko: fix invariant in _unread(). Also fixed
readlines() to behave like it should (return lines with "\n" appended).

Jeremy Hylton ee918cb487 Fix bug reported by Harri Pasanen: gzip + cPickle doesn't work. The
problem was a couple of bugs in the readline implementation.

1. Include the '\n' in the string returned by readline
2. Bug calculating new buffer size in _unread

Also remove unncessary import of StringIO

Guido van Rossum 45e2fbc2e7 Mass check-in after untabifying all files that need it. 1998-03-26 21:13:24 +00:00
Guido van Rossum b16a3b8450 (This fix is really by Jeremy)
Here's my suggested replacement for gzip.py for 1.5.1.  I've
re-implemeted methods readline and readlines, added an _unread, and
tweaked read and _read.

I tried a more complicated buffer scheme for unread (using a list of
strings and string.join), but it was more complicated and slower.
This version is a lot faster than the current version and is still
pretty simple.

Guido van Rossum 51ca6e3e42 When there's no filename, don't make one up.
Added _test() that behaves (a bit) like gzip.
Fix a comment (*sequential* access is okay -- *random* access it out!)
1997-12-30 20:09:08 +00:00
Guido van Rossum 68de37973f Add the option to pass an open file object to GzipFile. This obviates
the need for the StringIO subclass.

Guido van Rossum 1526219431 Adding Jeremy Hylton's gzip module.
This requires Andrew Kuchling's zlib extension module.
It still needs some doc strings.
