Jason Tishler 6bc06eca70 Bug #794140: cygwin builds do not embed
The embed2.diff patch solves the user's problem by exporting the missing
symbols from the Python core so Python can be embedded in another Cygwin
application (well, at lest vim).

Neil Schemenauer 00b0966f20 Don't use the module object setattr when importing submodules. Instead,
operate on the module dictionary directly.  This prevents spurious
depreciation warnings from being raised if a submodule name shadows
a builtin name.

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.

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.

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.

2002-02-26 11:41:34 +00:00
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.

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).

(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???)

Tim Peters d1e87a8288 More MacOSX fiddling. As noted in a comment, I believe all variations

Tim Peters dbe6ebbeff More fiddling w/ the new-fangled Mac import code. 2001-03-01 08:47:29 +00:00
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 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.
2001-02-28 05:34:27 +00:00
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.
2001-02-20 21:43:24 +00:00
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.

2001-02-02 19:12:16 +00:00
Tim Peters d9b9ac855c It's unclear whether PyMarshal_XXX() are part of the public or private API.
They're named as if public, so I did a Bad Thing by changing
PyMarshal_ReadObjectFromFile() to suck up the remainder of the file in one
gulp:  anyone who counted on that leaving the file pointer merely at the
end of the next object would be screwed.  So restored
PyMarshal_ReadObjectFromFile() to its earlier state, renamed the new greedy
code to PyMarshal_ReadLastObjectFromFile(), and changed Python internals to
call the latter instead.
2001-01-28 00:27:39 +00:00
Jeremy Hylton 64949cb753 PEP 227 implementation
The majority of the changes are in the compiler.  The mainloop changes
primarily to implement the new opcodes and to pass a function's
closure to eval_code2().  Frames and functions got new slots to hold
the closure.

Include/compile.h
    Add co_freevars and co_cellvars slots to code objects.
    Update PyCode_New() to take freevars and cellvars as arguments
Include/funcobject.h
    Add func_closure slot to function objects.
    Add GetClosure()/SetClosure() functions (and corresponding
    macros) for getting at the closure.
Include/frameobject.h
    PyFrame_New() now takes a closure.
Include/opcode.h
    Add four new opcodes: MAKE_CLOSURE, LOAD_CLOSURE, LOAD_DEREF,
    STORE_DEREF.
    Remove comment about old requirement for opcodes to fit in 7
    bits.
compile.c
    Implement changes to code objects for co_freevars and co_cellvars.

    Modify symbol table to use st_cur_name (string object for the name
    of the current scope) and st_cur_children (list of nested blocks).
    Also define st_nested, which might more properly be called
    st_cur_nested.  Add several DEF_XXX flags to track def-use
    information for free variables.

    New or modified functions of note:
    com_make_closure(struct compiling *, PyCodeObject *)
        Emit LOAD_CLOSURE opcodes as needed to pass cells for free
        variables into nested scope.
    com_addop_varname(struct compiling *, int, char *)
        Emits opcodes for LOAD_DEREF and STORE_DEREF.
    get_ref_type(struct compiling *, char *name)
        Return NAME_CLOSURE if ref type is FREE or CELL
    symtable_load_symbols(struct compiling *)
        Decides what variables are cell or free based on def-use info.
        Can now raise SyntaxError if nested scopes are mixed with
        exec or from blah import *.
    make_scope_info(PyObject *, PyObject *, int, int)
        Helper functions for symtable scope stack.
    symtable_update_free_vars(struct symtable *)
        After a code block has been analyzed, it must check each of
        its children for free variables that are not defined in the
        block.  If a variable is free in a child and not defined in
        the parent, then it is defined by block the enclosing the
        current one or it is a global.  This does the right logic.
    symtable_add_use() is now a macro for symtable_add_def()
    symtable_assign(struct symtable *, node *)
        Use goto instead of for (;;)

    Fixed bug in symtable where name of keyword argument in function
    call was treated as assignment in the scope of the call site. Ex:
        def f():
            g(a=2) # a was considered a local of f

ceval.c
    eval_code2() now take one more argument, a closure.
    Implement LOAD_CLOSURE, LOAD_DEREF, STORE_DEREF, MAKE_CLOSURE>

    Also: When name error occurs for global variable, report that the
    name was global in the error mesage.

Objects/frameobject.c
    Initialize f_closure to be a tuple containing space for cellvars
    and freevars.  f_closure is NULL if neither are present.
Objects/funcobject.c
    Add support for func_closure.
Python/import.c
    Change the magic number.
Python/marshal.c
    Track changes to code objects.

Barry Warsaw 84294487df _PyImport_Fini(): Closed small memory leak when an embedded app calls
Py_Initialize()/Py_Finalize() in a loop.  _PyImport_Filetab needed to
be deallocated.  Partial closure of SF #110681, Jitterbug PR#398.

Tim Peters 42c83afd14 The 2.0b2 change to write .pyc files in exclusive mode (if possible)
unintentionally caused them to get written in text mode under Windows.
As a result, when .pyc files were later read-- in binary mode --the
magic number was always wrong (note that .pyc magic numbers deliberately
include \r and \n characters, so this was "good" breakage, 100% across
all .pyc files, not random corruption in a subset).  Fixed that.

Thomas Wouters dd13e4f91f Replace the run-time 'future-bytecode-stream-inspection' hack to find out
how 'import' was called with a compiletime mechanism: create either a tuple
of the import arguments, or None (in the case of a normal import), add it to
the code-block constants, and load it onto the stack before calling
IMPORT_NAME.

Thomas Wouters 5215225ea1 Apply SF patch #101135, adding 'import module as m' and 'from module import
name as n'. By doing some twists and turns, "as" is not a reserved word.

There is a slight change in semantics for 'from module import name' (it will
now honour the 'global' keyword) but only in cases that are explicitly
undocumented.

Thomas Wouters 0be5aab04d Merge UNPACK_LIST and UNPACK_TUPLE into a single UNPACK_SEQUENCE, since they
did the same anyway.

I'm not sure what to do with Tools/compiler/compiler/* -- that isn't part of
distutils, is it ? Should it try to be compatible with old bytecode version ?

Thomas Wouters 2f2370bfc9 Oops. One of last nights ANSIfication patches accidentily upped the bytecode
MAGIC number. When updating it next time, be sure it's higher than 50715 *
constants. (Shouldn't be a problem if everyone keeps to the proper
algorithm.)

Fred Drake 4c82b2366f Trent Mick <trentm@activestate.com>:
This patch fixes possible overflow in the use of
PyOS_GetLastModificationTime in getmtime.c and Python/import.c.

Currently PyOS_GetLastModificationTime returns a C long. This can
overflow on Win64 where sizeof(time_t) > sizeof(long). Besides it
should logically return a time_t anyway (this patch changes this).

As well, import.c uses PyOS_GetLastModificationTime for .pyc
timestamping.  There has been recent discussion about the .pyc header
format on python-dev.  This patch adds oveflow checking to import.c so
that an exception will be raised if the modification time
overflows. There are a few other minor 64-bit readiness changes made
to the module as well:

- size_t instead of int or long for function-local buffer and string
length variables

- one buffer overflow check was added (raises an exception on possible
overflow, this overflow chance exists on 32-bit platforms as well), no
other possible buffer overflows existed (from my analysis anyway)

Closes SourceForge patch #100509.

Guido van Rossum b18618dab7 Vladimir Marangozov's long-awaited malloc restructuring.
For more comments, read the patches@python.org archives.
For documentation read the comments in mymalloc.h and objimpl.h.

(This is not exactly what Vladimir posted to the patches list; I've
made a few changes, and Vladimir sent me a fix in private email for a
problem that only occurs in debug mode.  I'm also holding back on his
change to main.c, which seems unnecessary to me.)

Guido van Rossum 96774c1347 Marc-Andre Lemburg:
Changed all references to the MAGIC constant to use a global
pyc_magic instead. This global is initially set to MAGIC, but can be
changed by the _PyImport_Init() function to provide for
special features implemented in the compiler which are settable
using command line switches and affect the way PYC files are
generated.

Currently this change is only done for the -U flag.
