Neal Norwitz 08ea61ad45 Remove PyArg_ParseTuple() for methods which take no args,
use METH_NOARGS instead
2003-02-17 18:18:00 +00:00
Neal Norwitz 2294c0d4ec Cleanup from patch #683257:
Add missing INCREFs and re-indent returns to be consistent.
 Add \n\ for lines in docstring
 Add a pathetic test
 Add docs

Guido van Rossum c4f4ca91e1 Provide access to the import lock, fixing SF bug #580952. This is
mostly from SF patch #683257, but I had to change unlock_import() to
return an error value to avoid fatal error.

Should this be backported?  The patch requested this, but it's a new
feature.

Jack Jansen 9363dca3f8 MacPython-OS9 specific fix: If there are non-string items on sys.path don't try to intern them. This has the theoretical problem that resource filenames on sys.path cannot be unicode objects, but in practice that shouldn't matter. 2003-01-24 16:15:45 +00:00
Just van Rossum 52e14d640b PEP 302 + zipimport:
- new import hooks in import.c, exposed in the sys module
- new module called 'zipimport'
- various changes to allow bootstrapping from zip files

I hope I didn't break the Windows build (or anything else for that
matter), but then again, it's been sitting on sf long enough...

Regarding the latest discussions on python-dev: zipimport sets
pkg.__path__ as specified in PEP 273, and likewise, sys.path item such as
/path/to/Archive.zip/subdir/ are supported again.

Martin v. Löwis 79acb9edfa Patch #614055: Support OpenVMS. 2002-12-06 12:48:53 +00:00
Just van Rossum 3eb166b49b Slightly improved version of patch #642578: "Expose PyImport_FrozenModules
in imp". This adds two functions to the imp module: get_frozenmodules()
and set_frozenmodules().

Guido van Rossum f689492070 Because MWH changed the bytecode again, moved the magic number *back*
to 62011.  This should get the snake-farm to throw away its old .pyc
files, amongst others.

[ 587993 ] SET_LINENO killer

Many sundry changes to document and adapt to this change.

Walter Dörwald 3430d70e03 Apply diff2.txt from SF patch http://www.python.org/sf/566999
This patch enhances Python/import.c/find_module() so
that unicode objects found in sys.path will be treated
as legal directory names (The current code ignores
anything that is not a str). The unicode name is
converted to str using Py_FileSystemDefaultEncoding.

Guido van Rossum 5e2c5fa1bd imp_load_module(): correct and comment the sense of the test for '+'
in the mode (it's forbidden).
2002-05-30 17:33:07 +00:00
Jeremy Hylton 4ae6faed9f Cover a few corners in the 'U' mode integration to make imp work.
get_file() must convert 'U' to "r" PY_STDIOTEXTMODE before calling
fopen().

imp_load_module() must accept 'r' or 'U' or something with '+'.

Also reflow some long lines.
2002-05-30 17:15:25 +00:00
Jack Jansen c88da1faa5 File modes in filedescr entries are also passed to Python, so we now put "U"
in there, and convert it to "rb" (or "r" for non-universal-newline builds)
before passing it to fopen().

Fixes #561326.
2002-05-28 10:58:19 +00:00
Jack Jansen 7b8c7546eb Mass checkin of universal newline support.
Highlights: import and friends will understand any of \r, \n and \r\n
as end of line. Python file input will do the same if you use mode 'U'.
Everything can be disabled by configuring with --without-universal-newlines.

See PEP278 for details.

Marc-André Lemburg bd3be8f0ca Fix to the UTF-8 encoder: it failed on 0-length input strings.
Fix for the UTF-8 decoder: it will now accept isolated surrogates
(previously it raised an exception which causes round-trips to
fail).

Added new tests for UTF-8 round-trip safety (we rely on UTF-8 for
marshalling Unicode objects, so we better make sure it works for
all Unicode code points, including isolated surrogates).

Bumped the PYC magic in a non-standard way -- please review. This
was needed because the old PYC format used illegal UTF-8 sequences
for isolated high surrogates which now raise an exception.

Jack Jansen 550fdae2f5 On the macintosh don't take a quick exit in find_module() for frozen submodule imports: the frozen import goes through a different mechanism. 2001-10-30 13:08:39 +00:00
Fred Drake 9cd0efcee9 Use PyDict_Copy() and PyDict_Update() instead of using PyObject_CallMethod()
to call the corresponding methods.  This is not a performance improvement
since the times are still swamped by disk I/O, but cleans up the code just
a little.

Guido van Rossum e2ae77b8b8 SF patch #474590 -- RISC OS support 2001-10-24 20:42:55 +00:00
Guido van Rossum 8f4d3316de First part of SF patch #416704: More robust freeze, by Toby Dickenson.
This fixes the behavior reported by SF bug #404545, where a file
x.y.py could be imported by the statement "import x.y" when there's a
frozen package x (I believe even if x.y also exists as a frozen
module).

Guido van Rossum f48f11cd79 SF Patch #441791, with changes: when "import foo.bar" fails with an
exception in the execution of bar, ensure that foo.bar exists.
(Previously, while sys.modules['foo.bar'] would exist, foo.bar would
only be created upon successful execution of bar.  This is
inconvenient; some would say wrong. :-)

Tim Peters 0f9431fb18 SF bug #438295: [Windows] __init__.py cause strange behavior
Probable fix (the bug report doesn't have enough info to say for sure).
find_init_module():  Insist on a case-sensitive match for __init__ files.
Given __INIT__.PY instead, find_init_module() thought that was fine, but
the later attempt to do find_module("__INIT__.PY") didn't and its caller
silently suppressed the resulting ImportError.  Now find_init_module()
refuses to accept __INIT__.PY to begin with.
Bugfix candidate; specific to platforms with case-insensitive filesystems.
2001-07-05 03:47:53 +00:00
Tim Peters cab3f68f61 SF bug #417093: Case sensitive import: dir and .py file w/ same name
Directory containing
    Spam.py
    spam/__init__.py
Then "import Spam" caused a SystemError, because code checking for
the existence of "Spam/__init__.py" finds it on a case-insensitive
filesystem, but then bails because the directory it finds it in
doesn't match case, and then old code assumed that was still an error
even though it isn't anymore.  Changed the code to just continue
looking in this case (instead of calling it an error).  So
    import Spam
and
    import spam
both work now.

Guido van Rossum 59d1d2b434 Iterators phase 1. This comprises:
new slot tp_iter in type object, plus new flag Py_TPFLAGS_HAVE_ITER
new C API PyObject_GetIter(), calls tp_iter
new builtin iter(), with two forms: iter(obj), and iter(function, sentinel)
new internal object types iterobject and calliterobject
new exception StopIteration
new opcodes for "for" loops, GET_ITER and FOR_ITER (also supported by dis.py)
new magic number for .pyc files
new special method for instances: __iter__() returns an iterator
iteration over dictionaries: "for x in dict" iterates over the keys
iteration over files: "for x in file" iterates over lines

TODO:

documentation
test suite
decide whether to use a different way to spell iter(function, sentinal)
decide whether "for key in dict" is a good idea
use iterators in map/filter/reduce, min/max, and elsewhere (in/not in?)
speed tuning (make next() a slot tp_next???)
