Neal Norwitz aa754b70b0 Remove unused file spotted by Paul Hankin 2007-03-21 06:39:48 +00:00
Jeremy Hylton dd2cf1cb84 Clean up formatting of this file.
The file should now follow PEP 7, except that it uses 4 space indents
(in the style of Py3k).  This particular code would be really hard to
read with the regular tab idents.

Other changes:
 - reflow long lines
 - change multi-line conditionals to have test at end of line

Georg Brandl 7b9c555520 Bug #1678647: write a newline after printing an exception in any
case, even when converting the value to a string failed.
2007-03-12 14:30:05 +00:00
Georg Brandl 871f1bc601 Backport from Py3k branch:
Patch #1591665: implement the __dir__() special function lookup in PyObject_Dir.

Had to change a few bits of the patch because classobjs and __methods__ are still
in Py2.6.

Georg Brandl aa2321b0f8 Patch #703779: unset __file__ in __main__ after running a file. This
makes the filenames the warning module prints much more sensible when
a PYTHONSTARTUP file is used.

Georg Brandl 49aafc9f2c Variant of patch #697613: don't exit the interpreter on a SystemExit

on other exceptions or normal program exit.

Neal Norwitz f83b751f4b SF #1669182, 2.5 was already fixed. Just assert in 2.6 since string exceptions
are gone.
2007-02-26 23:48:27 +00:00
Neal Norwitz 88516a6039 When printing an unraisable error, don't print exceptions. before the name.
This duplicates the behavior whening normally printing exceptions.

Neal Norwitz 7b7d1c8282 Fix a couple of problems in generating the AST code:
* use %r instead of backticks since backticks are going away in Py3k
 * PyArena_Malloc() already sets PyErr_NoMemory so we don't need to do it again
 * the signature for ast2obj_int incorrectly used a bool, rather than a long

Jeremy Hylton c5ceb251b3 Fix crash in exec when unicode filename can't be decoded.
I can't think of an easy way to test this behavior.  It only occurs
when the file system default encoding and the interpreter default
encoding are different, such that you can open the file but not decode
its name.

Brett Cannon 0db62aaf09 Modify Parser/asdl_c.py so that the __version__ number for Python/Python-ast.c
is specified at the top of the file.  Also add a note that Python/Python-ast.c
needs to be committed separately after a change to the AST grammar to capture
the revision number of the change (which is what __version__ is set to).

Brett Cannon 129bd52146 No more raising of string exceptions!
The next step of PEP 352 (for 2.6) causes raising a string exception to trigger
a TypeError.  Trying to catch a string exception raises a DeprecationWarning.
References to string exceptions has been removed from the docs since they are
now just an error.

Thomas Wouters afea529088 SF patch #1630975: Fix crash when replacing sys.stdout in sitecustomize
When running the interpreter in an environment that would cause it to set
stdout/stderr/stdin's encoding, having a sitecustomize that would replace
them with something other than PyFile objects would crash the interpreter.
Fix it by simply ignoring the encoding-setting for non-files.

This could do with a test, but I can think of no maintainable and portable
way to test this bug, short of adding a sitecustomize.py to the buildsystem
and have it always run with it (hmmm....)

Neal Norwitz 21997afb0c Fix bug #1565514, SystemError not raised on too many nested blocks.
It seems like this should be a different error than SystemError, but
I don't have any great ideas and SystemError was raised in 2.4 and earlier.

Will backport.
2006-10-28 21:19:07 +00:00
Neal Norwitz 837ce9389e Add some asserts. In sysmodule, I think these were to try to silence
some warnings from Klokwork.  They verify the assumptions of the format
of svn version output.

The assert in the thread module helped debug a problem on HP-UX.

Andrew M. Kuchling 1f3ebe0b10 [Bug #1542016] Report PCALL_POP value. This makes the return value of sys.callstats() match its docstring.
Backport candidate.  Though it's an API change, this is a pretty obscure
portion of the API.

Armin Rigo 7ccbca93a2 Forward-port of r52136,52138: a review of overflow-detecting code.
* unified the way intobject, longobject and mystrtoul handle
  values around -sys.maxint-1.

* in general, trying to entierely avoid overflows in any computation
  involving signed ints or longs is extremely involved.  Fixed a few
  simple cases where a compiler might be too clever (but that's all
  guesswork).

* more overflow checks against bad data in marshal.c.

* 2.5 specific: fixed a number of places that were still confusing int
  and Py_ssize_t.  Some of them could potentially have caused
  "real-world" breakage.

* list.pop(x): fixing overflow issues on x was messy.  I just reverted
  to PyArg_ParseTuple("n"), which does the right thing.  (An obscure
  test was trying to give a Decimal to list.pop()... doesn't make
  sense any more IMHO)

* trying to write a few tests...

Jeremy Hylton 82271f13e7 Fix for SF bug 1569998: break permitted inside try.
The compiler was checking that there was something on the fblock
stack, but not that there was a loop on the stack.  Fixed that and
added a test for the specific syntax error.

Bug fix candidate.

Georg Brandl ec6c2dfb63 Forward-port of rev. 51857:
Building with HP's cc on HP-UX turned up a couple of problems.
_PyGILState_NoteThreadState was declared as static inconsistently.
Make it static as it's not necessary outside of this module.

Some tests failed because errno was reset to 0. (I think the tests
that failed were at least: test_fcntl and test_mailbox).
Ensure that errno doesn't change after a call to Py_END_ALLOW_THREADS.
This only affected debug builds.

Neal Norwitz dac090d3e6 Bug #1520864 (again): unpacking singleton tuples in list comprehensions and
generator expressions (x for x, in ... ) works again.

Sigh, I only fixed for loops the first time, not list comps and genexprs too.
I couldn't find any more unpacking cases where there is a similar bug lurking.

This code should be refactored to eliminate the duplication.  I'm sure
the listcomp/genexpr code can be refactored.  I'm not sure if the for loop
can re-use any of the same code though.

Will backport to 2.5 (the only place it matters).

Neal Norwitz 8a87f5d37e Patch #1538606, Patch to fix __index__() clipping.
I modified this patch some by fixing style, some error checking, and adding

Neal Norwitz edb2168079 This code is actually not used unless WITHOUT_COMPLEX is defined.

Neal Norwitz 84167d09cd Even though _Py_Mangle() isn't truly public anyone can call it and
there was no verification that privateobj was a PyString.  If it wasn't

I wonder if this should be PyString_CheckExact?  Must identifiers be strings
or can they be subclasses?

Neal Norwitz 6f5ff3f3eb Klocwork made another run and found a bunch more problems.

Neal Norwitz 4ffedadb10 Bug #1191458: tracing over for loops now produces a line event
on each iteration.  I'm not positive this is the best way to handle
this.  I'm also not sure that there aren't other cases where
the lnotab is generated incorrectly.  It would be great if people
that use pdb or tracing could test heavily.

Also:
 * Remove dead/duplicated code that wasn't used/necessary
   because we already handled the docstring prior to entering the loop.
 * add some debugging code into the compiler (#if 0'd out).

Phillip J. Eby f7575d0cb7 Bug #1529871: The speed enhancement patch #921466 broke Python's compliance

used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
excessive filesystem operations during imports.
2006-07-28 21:12:07 +00:00
Tim Peters bc24eee333 Bug #1521947: possible bug in mystrtol.c with recent gcc.
In general, C doesn't define anything about what happens when
an operation on a signed integral type overflows, and PyOS_strtol()
did several formally undefined things of that nature on signed
longs.  Some version of gcc apparently tries to exploit that now,
and PyOS_strtol() could fail to detect overflow then.

Tried to repair all that, although it seems at least as likely to me
that we'll get screwed by bad platform definitions for LONG_MIN
and/or LONG_MAX now.  For that reason, I don't recommend backporting
this.

Note that I have no box on which this makes a lick of difference --
can't really test it, except to note that it didn't break anything
on my boxes.

Silent change:  PyOS_strtol() used to return the hard-coded 0x7fffffff
in case of overflow.  Now it returns LONG_MAX.  They're the same only on
32-bit boxes (although C doesn't guarantee that either ...).

in a huge "#ifdef WITH_THREAD" block (I didn't realize it /was/ in
one).

Changed test_sys's test_current_frames() so it passes with or without
thread supported compiled in.

Note that test_sys fails when Python is compiled without threads,
but for an unrelated reason (the old test_exit() fails with an
indirect ImportError on the `thread` module).  There are also
other unrelated compilation failures without threads, in extension
modules (like ctypes); at least the core compiles again.

Do we really support --without-threads?  If so, there are several
problems remaining.

v2 can be NULL if exception2 is NULL.  I don't think that condition can happen,
but I'm not sure it can't either.  Now the code will protect against either
being NULL.

Tim Peters 02f1d0dc78 _PySys_Init(): It's rarely a good idea to size a buffer to the
exact maximum size someone guesses is needed.  In this case, if
we're really worried about extreme integers, then "cp%d" can
actually need 14 bytes (2 for "cp" + 1 for \0 at the end +
11 for -(2**31-1)).  So reserve 128 bytes instead -- nothing is
actually saved by making a stack-local buffer tiny.
2006-06-06 00:25:07 +00:00
Brett Cannon 4f7a7220c1 Add 3 more bytes to a buffer to cover constants in string and null byte on top of 10 possible digits for an int.

are multiple causes with seemingly no immediate prospects for
repairing them.  See python-dev discussion.

Tim Peters 7df5e7f4b2 Patch 1145039.
set_exc_info(), reset_exc_info():  By exploiting the
likely (who knows?) invariant that when an exception's
`type` is NULL, its `value` and `traceback` are also NULL,
save some cycles in heavily-executed code.

This is a "a kronar saved is a kronar earned" patch:  the
speedup isn't reliably measurable, but it obviously does
reduce the operation count in the normal (no exception
raised) path through PyEval_EvalFrameEx().

The tim-exc_sanity branch tries to push this harder, but
is still blowing up (at least in part due to pre-existing
subtle bugs that appear to have no other visible
consequences!).

Not a bugfix candidate.

Tim Peters b713ec2531 Bug #1334662 / patch #1335972: int(string, base) wrong answers.
In rare cases of strings specifying true values near sys.maxint,
and oddball bases (not decimal or a power of 2), int(string, base)
could deliver insane answers.  This repairs all such problems, and
also speeds string->int significantly.  On my box, here are %
speedups for decimal strings of various lengths:

length speedup
------ -------
 1       12.4%
 2       15.7%
 3       20.6%
 4       28.1%
 5       33.2%
 6       37.5%
 7       41.9%
 8       46.3%
 9       51.2%
10       19.5%
11       19.9%
12       23.9%
13       23.7%
14       23.3%
15       24.9%
16       25.3%
17       28.3%
18       27.9%
19       35.7%

Note that the difference between 9 and 10 is the difference between
short and long Python ints on a 32-bit box.  The patch doesn't
actually do anything to speed conversion to long:  the speedup is
due to detecting "unsigned long" overflow more quickly.

This is a bugfix candidate, but it's a non-trivial patch and it
would be painful to separate the "bug fix" from the "speed up" parts.

Thomas Wouters 9df4e6f673 - Add new Warning class, ImportWarning
- Warn-raise ImportWarning when importing would have picked up a directory
   as package, if only it'd had an __init__.py. This swaps two tests (for
   case-ness and __init__-ness), but case-test is not really more expensive,
   and it's not in a speed-critical section.

 - Test for the new warning by importing a common non-package directory on
   sys.path: site-packages

 - In regrtest.py, silence warnings generated by the build-environment
   because Modules/ (which is added to sys.path for Setup-created modules)
   has 'zlib' and '_ctypes' directories without __init__.py's.

Thomas Wouters 1ddba60e3d Define MAXPATHLEN to be at least PATH_MAX, if that's defined. Python uses
MAXPATHLEN-sized buffers for various output-buffers (like to realpath()),
and that's correct on BSD platforms, but not Linux (which uses PATH_MAX, and
does not define MAXPATHLEN.) Cursory googling suggests Linux is following a
newer standard than BSD, but in cases like this, who knows. Using the
greater of PATH_MAX and 1024 as a fallback for MAXPATHLEN seems to be the
most portable solution.

As note in Python.asdl says, we might want to rethink how attributes

the primary difference being how they are defined for all types within
a sum.

Also fix asdl_c so that constructors with int fields don't fail when
passed a zero value.

def foo((x)): was getting recognized as requiring tuple unpacking

	def foo((x,)):

test_inpsect was incorrect before.  I'm not sure why it was passing,
but that has been corrected with a test for both functions above.
This means the test (and therefore inspect.getargspec()) are broken in 2.4.

Tim Peters c9d78aa470 Years in the making.
objimpl.h, pymem.h:  Stop mapping PyMem_{Del, DEL} and PyMem_{Free, FREE}
to PyObject_{Free, FREE} in a release build.  They're aliases for the
system free() now.

_subprocess.c/sp_handle_dealloc():  Since the memory was originally
obtained via PyObject_NEW, it must be released via PyObject_FREE (or
_DEL).

pythonrun.c, tokenizer.c, parsermodule.c:  I lost count of the number of
PyObject vs PyMem mismatches in these -- it's like the specific
function called at each site was picked at random, sometimes even with
memory obtained via PyMem getting released via PyObject.  Changed most
to use PyObject uniformly, since the blobs allocated are predictably
small in most cases, and obmalloc is generally faster than system
mallocs then.

If extension modules in real life prove as sloppy as Python's front
end, we'll have to revert the objimpl.h + pymem.h part of this patch.
Note that no problems will show up in a debug build (all calls still go
thru obmalloc then). Problems will show up only in a release build, most
likely segfaults.

Thomas Wouters f7f438ba3b SF patch #1438387, PEP 328: relative and absolute imports.
- IMPORT_NAME takes an extra argument from the stack: the relativeness of
   the import. Only passed to __import__ when it's not -1.

 - __import__() takes an optional 5th argument for the same thing; it
   __defaults to -1 (old semantics: try relative, then absolute)

 - 'from . import name' imports name (be it module or regular attribute)
   from the current module's *package*. Likewise, 'from .module import name'
   will import name from a sibling to the current module.

 - Importing from outside a package is not allowed; 'from . import sys' in a
   toplevel module will not work, nor will 'from .. import sys' in a
   (single-level) package.

 - 'from __future__ import absolute_import' will turn on the new semantics
   for import and from-import: imports will be absolute, except for
   from-import with dots.

Includes tests for regular imports and importhooks, parser changes and a
NEWS item, but no compiler-package changes or documentation changes.

Tim Peters f4e6928c4d Patch 1413181, by Gabriel Becedillas.
PyThreadState_Delete():  if the auto-GIL-state machinery knows about
the thread state, forget it (since the thread state is being deleted,
continuing to remember it can't help, but can hurt if another thread
happens to get created with the same thread id).

I'll backport to 2.4 next.

Thomas Wouters dca3b9c797 PEP 308 implementation, including minor refdocs and some testcases. It
breaks the parser module, because it adds the if/else construct as well as
two new grammar rules for backward compatibility. If no one else fixes
parsermodule, I guess I'll go ahead and fix it later this week.

The TeX code was checked with texcheck.py, but not rendered. There is
actually a slight incompatibility:

>>> (x for x in lambda:0)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: iteration over non-sequence

changes into

>>> (x for x in lambda: 0)
  File "<stdin>", line 1
    (x for x in lambda: 0)
                     ^
SyntaxError: invalid syntax

Since there's no way the former version can be useful, it's probably a
bugfix ;)

Implement change suggested by Jiwon Seo on python-dev.
['(' gen_for ')'] is redundant with test, so remove it.

Neal Norwitz 20dd93f427 Fix compiler warning on amd64. We can't use zd here since this is

Brett Cannon 82a9394237 Add doc discussing how AST compiler is structured and designed.
It is out of date, though, thanks to lacking info on the arena API.  It also
should eventually be removed in favor of updating PEP 339.

Jeremy Hylton c960f26044 Improved handling of syntax errors.
Expand set of errors caught in set_context().  Some new errors, some
old error messages changed for consistency.

Fixed error checking in generator expression code.  The first set of
tests were impossible condition given the grammar.  In general, the
ast code uses REQ() for those sanity checks.

Fix some error handling for augmented assignments.  As comments in the
code explain, set_context() ought to work here, but I got unexpected
crashes when I tried it.  Should come back to this.

Add note to Grammar that yield expression is a special case.

Add doctest cases for SyntaxErrors raised by ast.c.

Tim Peters 5db42c4c50 alias_for_import_name(): Dueling compiler warnings ;-)
Squash new warnings from VC 7.1 about mixing signed and
unsigned types in comparisons.  I can see why `len` was
changed to size_t here, but don't see why `i` was also
changed.  Change `i` back to int.

Tim Peters d8fe7ab711 analyze_cells(): This no longer compiled under VC 7.1.

Neal Norwitz 51abbc7b4a Fix Armin's bug 1333982. He found it, he didn't created it :-)
This code generated a C assertion:
        assert 1, ([s for s in x] +
                   [s for s in x])
        pass

assert was completely broken, it needed to use the proper block.
compiler_use_block() is now no longer used, so remove it.
