Mark Dickinson 154b7ad07e Issue #1530559: When packing a non-integer with any integer conversion
code using struct.pack, attempt to convert to an integer first using
the argument's __int__ method (if present).  Also raise a
DeprecationWarning for any such usage of __int__.

This fixes a regression from 2.6, where some (but not all) integer
conversion codes already used __int__.

Mark Dickinson 1c0c78c61f Fix incorrect stacklevel for DeprecationWarnings originating from the struct module.
Also clean up related tests in test_struct.
The stacklevel fix should be backported to 2.6 once that branch is unfrozen.

Gregory P. Smith 2839985c7e The unittest.TestCase.assertEqual() now displays the differences in lists,
tuples, dicts and sets on failure.

Many new handy type and comparison specific assert* methods have been added
that fail with error messages actually useful for debugging.  Contributed in
by Google and completed with help from mfoord and GvR at PyCon 2009 sprints.

Discussion lives in http://bugs.python.org/issue2578.

Brett Cannon 672237dc6c warnings.catch_warnings() now returns a list or None instead of the custom
WarningsRecorder object. This makes the API simpler to use as no special object
must be learned.

Closes issue 3781.

Gregory P. Smith 9d53457e59 Merge in release25-maint r60793:
Added checks for integer overflows, contributed by Google. Some are
 only available if asserts are left in the code, in cases where they
 can't be triggered from Python code.

Mark Dickinson c23b8a7af9 Issue 705836: Fix struct.pack(">f", 1e40) to behave consistently
across platforms:  it should now raise OverflowError on all
platforms.  (Previously it raised OverflowError only on
non IEEE 754 platforms.)

Also fix the (already existing) test for this behaviour
so that it actually raises TestFailed instead of just
referencing it.

Thomas Heller f3c0559b5e Issue 1872: Changed the struct module typecode from 't' to '?', for
compatibility with PEP3118.

Brett Cannon 2ee4128e9b Remove test.test_support.guard_warnings_filter.
test.test_support.catch_warning is more full-featured and provides the same
functionality.

Since guard_warnings_filter was added in 2.6 there is no
backwards-compatibility issues.

Bob Ippolito e6c9f982a0 Fix #1530559, struct.pack raises TypeError where it used to convert.
Passing float arguments to struct.pack when integers are expected
now triggers a DeprecationWarning.

Tim Peters 852eae1bc1 Access _struct attributes directly instead of mucking with getattr.
string_reverse():  Simplify.

assertRaises():  Raise TestFailed on failure.

test_unpack_from(), test_pack_into(), test_pack_into_fn():  never
use `assert` to test for an expected result (it doesn't test anything
when Python is run with -O).

Martin Blais af2ae72cb2 Fixes in struct and socket from merge reviews.
- Following Guido's comments, renamed

  * pack_to -> pack_into
  * recv_buf -> recv_into
  * recvfrom_buf -> recvfrom_into

- Made fixes to _struct.c according to Neal Norwitz comments on the checkins
  list.

- Converted some ints into the appropriate -- I hope -- ssize_t and size_t.

Tim Peters aba19bc45f deprecated_err(): Stop bizarre warning messages when the tests
are run in the order:

    test_genexps (or any other doctest-based test)
    test_struct
    test_doctest

The `warnings` module needs an advertised way to save/restore
its internal filter list.

Martin Blais 2856e5f390 Support for buffer protocol for socket and struct.
* Added socket.recv_buf() and socket.recvfrom_buf() methods, that use the buffer
  protocol (send and sendto already did).

* Added struct.pack_to(), that is the corresponding buffer compatible method to
  unpack_from().

* Fixed minor typos in arraymodule.

Tim Peters d50ade68ec SF bug 705836: struct.pack of floats in non-native endian order
pack_float, pack_double, save_float:  All the routines for creating
IEEE-format packed representations of floats and doubles simply ignored
that rounding can (in rare cases) propagate out of a long string of
1 bits.  At worst, the end-off carry can (by mistake) interfere with
the exponent value, and then unpacking yields a result wrong by a factor
of 2.  In less severe cases, it can end up losing more low-order bits
than intended, or fail to catch overflow *caused* by rounding.

Bugfix candidate, but I already backported this to 2.2.

In 2.3, this code remains in severe need of refactoring.

Guido van Rossum 68468eba63 Get rid of many apply() calls. 2003-02-27 20:14:51 +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 0891ac017d The 'p' (Pascal string) pack code acts unreasonably when the string size
and count exceed 255.  Changed to preserve as much of the string as
possible (instead of count%256 characters).
2001-09-15 02:35:15 +00:00
Tim Peters 3eec38af37 Added "i" and "l" to the list of std-mode struct codes that don't range-
check correctly on pack().  While these were checking OK on my 32-bit box,
Mark Favas reported failures on a 64-bit box (alas, easy to believe).

Tim Peters 17e17d4406 Generalize the new qQ std-mode tests to all int codes (bBhHiIlLqQ).
Unfortunately, the std-mode bBhHIL codes don't do any range-checking; if
and when some of those get fixed, remove their letters from the
IntTester.BUGGY_RANGE_CHECK string.  In the meantime, a msg saying that
range-tests are getting skipped is printed to stdout whenever one is
skipped.
