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.

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).
