Martin v. Löwis 6238d2b024 Patch #569753: Remove support for WIN16.

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.

Neal Norwitz 7fdcb41131 Fix SF bug # 561858 Assertion with very long lists
Write 4 bytes for co_stacksize, etc. to prevent writing out
bad .pyc files which can cause a crash when read back in.

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.

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.

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???)

Tim Peters 677898a391 Thanks to Steven Majewski, finally putting MacOS X imports to bed for 2.1b1. 2001-03-02 03:28:03 +00:00
Tim Peters d1e87a8288 More MacOSX fiddling. As noted in a comment, I believe all variations
of these "search the directory" schemes (including this one) are still prone
to making mistakes.

Fred Drake c63d3e9453 Suppress a compiler warning under OpenVMS; time_t is unsigned on (at least)
the more recent versions of that platform, so we use the value (time_t)(-1)
as the error value.  This is the type used in the OpenVMS documentation:

http://www.openvms.compaq.com/commercial/c/5763p048.htm#inde

This closes SF tracker bug #404240.

Also clean up an exception message when detecting overflow of time_t values
beyond 4 bytes.

Tim Peters 430f5d401d In Steven's apparent absence, check in *something* with a non-zero chance
of making new-fangled Mac imports work again.  May not work, and may not
even compile on his boxes, but should be at worst very close on both.

Tim Peters 50d8d37b3f Implement PEP 235: Import on Case-Insensitive Platforms.
http://python.sourceforge.net/peps/pep-0235.html

Renamed check_case to case_ok.  Substantial code rearrangement to get
this stuff in one place in the file.  Innermost loop of find_module()
now much simpler and #ifdef-free, and I want to keep it that way (it's
bad enough that the innermost loop is itself still in an #ifdef!).

Windows semantics tested and are fine.

Jason, Cygwin *should* be fine if and only if what you did before "worked"
for case_ok.

Jack, the semantics on your flavor of Mac have definitely changed (see
the PEP), and need to be tested.  The intent is that your flavor of Mac
now work the same as everything else in the "lower left" box, including
respecting PYTHONCASEOK.

Steven, sorry, you did the most work here so far but you got screwed the
worst.  Happy to work with you on repairing it, but I don't understand
anything about all your Mac variants.  We need to add another branch (or
two, three, ...?) inside case_ok.  But we should not need to change
anything else.

Guido van Rossum 85cd1d690c The code in PyImport_Import() tried to save itself a bit of work and
save the __builtin__ module in a static variable.  But this doesn't
work across Py_Finalise()/Py_Initialize()!  It also doesn't work when
using multiple interpreter states created with PyInterpreterState_New().

So I'm ripping out this small optimization.

This was probably broken since PyImport_Import() was introduced in
1997!  We really need a better test suite for multiple interpreter
states and repeatedly initializing.

This fixes the problems Barry reported in Demo/embed/loop.c.

Marc-André Lemburg 3c61c3525f This modified version of a patch by Thomas Heller allows __import__
hooks to take over the Python import machinery at a very early stage
in the Python startup phase.

If there are still places in the Python interpreter which need to
bypass the __import__ hook, these places must now use
PyImport_ImportModuleEx() instead. So far no other places than in
the import mechanism itself have been identified.
