Gregory P. Smith 7b7ce7854c Fix issue1789: The tutorial contained a misuse of the struct module.
(also remove an unneeded import struct from test_largefile)

Jason Tishler 063606a0d5 test_largefile can leave its temp file open if one of many tests fail. On
platforms (e.g., Cygwin) that are "particular" about open files, this will
cause other regression tests that use the same temp file to fail:

    $ ./python.exe -E -tt Lib/test/regrtest.py -l
    test_largefile test_mmap test_mutants
    test_largefile
    test test_largefile failed -- got -1794967295L, but expected 2500000001L
    test_mmap
    test test_mmap crashed -- exceptions.IOError: [Errno 13] Permission denied: '@test'
    test_mutants
    test test_mutants crashed -- exceptions.IOError: [Errno 13] Permission denied: '@test'

This patch solves the problem by adding missing "try/finally" blocks. Note
that the "large" size of this patch is due to many white space changes --
otherwise, the patch is small.

I tested this patch under Red Hat Linux 8.0 too.

Guido van Rossum 3b10dc3554 Require 'largefile' resource for Mac OSX as well. 2002-12-02 10:42:30 +00:00
Barry Warsaw 04f357cffe Get rid of relative imports in all unittests. Now anything that
imports e.g. test_support must do so using an absolute package name
such as "import test.test_support" or "from test import test_support".

This also updates the README in Lib/test, and gets rid of the
duplicate data dirctory in Lib/test/data (replaced by
Lib/email/test/data).

Now Tim and Jack can have at it. :)

Tim Peters 8f01b680c8 Change Windows file.truncate() to (a) restore the original file position,
and (b) stop trying to prevent file growth.

Beef up the file.truncate() docs.

Change test_largefile.py to stop assuming that f.truncate() moves the
file pointer to the truncation point, and to verify instead that it leaves
the file position alone.  Remove the test for what happens when a
specified size exceeds the original file size (it's ill-defined, according
to the Single Unix Spec).

Tim Peters fb05db2cae file_truncate(): provide full "large file" support on Windows, by
dropping MS's inadequate _chsize() function.  This was inspired by
SF patch 498109 ("fileobject truncate support for win32"), which I
rejected.

libstdtypes.tex:  Someone who knows should update the availability
blurb.  For example, if it's available on Linux, it would be good to
say so.

test_largefile:  Uncommented the file.truncate() tests, and reworked to
do more.  The old comment about "permission errors" in the truncation
tests under Windows was almost certainly due to that the file wasn't open
for *write* access at this point, so of course MS wouldn't let you
truncate it.  I'd be appalled if a Unixish system did.

CAUTION:  Someone should run this test on Linux (etc) too.  The
truncation part was commented out before.  Note that test_largefile isn't
run by default.

Martin v. Löwis df8adcd7ba Ignore SIGXFSZ. Fixes #490453. 2001-12-11 17:57:26 +00:00
Guido van Rossum f49dcea233 Remove two XXX comments that have been resolved. 2001-09-10 15:03:48 +00:00
Guido van Rossum a31ddbbd7b Move the global variables 'size' and 'name' to the top -- these are
"module parameters", and used in the Windows test (which crashed
because size was undefined -- sigh).

Guido van Rossum 47f40343b3 Change the criteria for skipping the test.
If on Windows, we require the 'largefile' resource.

If not on Windows, we use a test that actually writes a byte beyond
the 2BG limit -- seeking alone is not sufficient, since on some
systems (e.g. Linux with glibc 2.2) the sytem call interface supports
large seek offsets but not all filesystem implementations do.

Note that on Windows, we do not use the write test: on Win2K, that
test can take a minute trying to zero all those blocks on disk, and on
Windows our code always supports large seek offsets (but again, not
all filesystems do).  This may mean that on Win95, or on certain other
backward filesystems, test_largefile will *fail*.

Tim Peters b8c0230a27 Dubious assumptions:
1. That seeking beyond the end of a file increases the size of a file.
2. That files so extended are magically filled with null bytes.

I find no support for either in the C std, and #2 in particular turns out
not to be true on Win32 (you apparently see whatever trash happened to be
on disk).  Left #1 intact, but changed the test to check only bytes it
explicitly wrote.  Also fiddled the "expected" vs "got" failure reports
to consistently use repr (%r) -- they weren't readable otherwise.

Tim Peters 6e13a562ae Enable large file support on Win32 systems.
Curious:  the MS docs say stati64 etc are supported even on Win95, but
Win95 doesn't support a filesystem that allows partitions > 2 Gb.

test_largefile:  This was opening its test file in text mode.  I have no
idea how that worked under Win64, but it sure needs binary mode on Win98.
BTW, on Win98 test_largefile runs quickly (under a second).

Guido van Rossum 198c1d8b59 Remove a debug print left in the code by Fred. 2001-09-05 17:52:31 +00:00
Barry Warsaw 7fdfc3885c Use test_support.requires() to decide whether additional largefile
tests should be run.
2001-08-20 22:37:34 +00:00
Guido van Rossum a5af2148ee When doing the quick test to see whether large files are supported,
catch IOError as well as OverflowError.  I found that on Tru64 Unix
this was raised; probably because the OS (or libc) doesn't support
large files but the architecture is 64 bits!

Fred Drake 004d5e6880 Make reindent.py happy (convert everything to 4-space indents!). 2000-10-23 17:22:08 +00:00
Fred Drake dce5641856 Make sure the temporary file is cleaned up even when we raise TestSkipped. 2000-10-23 16:38:20 +00:00
Trent Mick f29f47b38b Add largefile support for Linux64 and WIn64. Add test_largefile and some minor
change to regrtest.py to allow optional running of test_largefile ('cause it's
slow on Win64).
