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.

Gregory P. Smith dd96db63f6 This reverts r63675 based on the discussion in this thread:
http://mail.python.org/pipermail/python-dev/2008-June/079988.html

Python 2.6 should stick with PyString_* in its codebase.  The PyBytes_* names
in the spirit of 3.0 are available via a #define only.  See the email thread.

Christian Heimes 593daf545b Renamed PyString to PyBytes 2008-05-26 12:51:38 +00:00
Amaury Forgeot d'Arc 588ff93f13 Crashers of the day: Py_CLEAR must be used when there is a chance that the
function can be called recursively.
This was discussed in issue1020188.

In python codebase, all occurrences of Py_[X]DECREF(xxx->yyy) are suspect,
except when they appear in tp_new or tp_dealloc functions, or when
the member cannot be of a user-defined class.
Note that tp_init is not safe.

I do have a (crashing) example for every changed line.
Is it worth adding them to the test suite?

Example:

class SpecialStr(str):
    def __del__(self):
        s.close()

import cStringIO
s = cStringIO.StringIO(SpecialStr("text"))
s.close() # Segfault

Neal Norwitz 1ac754fa10 Check return result from Py_InitModule*(). This API can fail.
Probably should be backported.
2006-01-19 06:09:39 +00:00
Jeremy Hylton af68c874a6 Add const to several API functions that take char *.
In C++, it's an error to pass a string literal to a char* function
without a const_cast().  Rather than require every C++ extension
module to put a cast around string literals, fix the API to state the
const-ness.

I focused on parts of the API where people usually pass literals:
PyArg_ParseTuple() and friends, Py_BuildValue(), PyMethodDef, the type
slots, etc.  Predictably, there were a large set of functions that
needed to be fixed as a result of these changes.  The most pervasive
change was to make the keyword args list passed to
PyArg_ParseTupleAndKewords() to be a const char *kwlist[].

One cast was required as a result of the changes:  A type object
mallocs the memory for its tp_doc slot and later frees it.
PyTypeObject says that tp_doc is const char *; but if the type was
created by type_new(), we know it is safe to cast to char *.

Michael W. Hudson 10402a306f Patches #1298449 and #1298499: Add some missing checks for error
returns in cStringIO.c.  Thanks to Andrew Bennetts.

This must be a backport candidate.

Tim Peters 037b3ee44e Patch 1012740: cStringIO's truncate doesn't
truncate() left the stream position unchanged, which meant the
"truncated" data didn't go away:

>>> io.write('abc')
>>> io.truncate(0)
>>> io.write('xyz')
>>> io.getvalue()
'abcxyz'

Patch by Dima Dorfman.

Tim Peters e7c053233f sizeof(char) is 1, by definition, so get rid of that expression in
places it's just noise.

Raymond Hettinger 6ec099658a SF patch #907403: Improvements to cStringIO.writelines()
The writelines() method now accepts any iterable argument and writes
the lines one at a time rather than using ''.join(lines) followed by
a single write.  Results in considerable memory savings and makes
the method suitable for use with generator expressions.

Raymond Hettinger bc72c5ae8b Speed-up the joiner call by avoiding Py_BuildValue(). 2004-02-27 10:30:49 +00:00
Raymond Hettinger 8ae4689657 Simplify and speedup uses of Py_BuildValue():
* Py_BuildValue("(OOO)",a,b,c)  -->  PyTuple_Pack(3,a,b,c)
* Py_BuildValue("()",a)         -->  PyTuple_New(0)
* Py_BuildValue("O", a)         -->  Py_INCREF(a)

Skip Montanaro eb2f0612e1 reverting to 2.41 version (distinct tp_names) - will add verbiage to the
docs
2003-08-11 14:51:15 +00:00
Skip Montanaro e138828d03 shit - just change the visible name, not the comments - strictly speaking,
the tp_name is not correct, but what's exposed to users is known visibly as
"StringIO", not "StringI" or "StringO".

Martin v. Löwis 14f8b4cfcb Patch #568124: Add doc string macros. 2002-06-13 20:33:02 +00:00
Guido van Rossum a883a3d5fd See discussion at SF bug 547537.
Unicode objects are currently taken as binary data by the write()
method.  This is not what Unicode users expect, nor what the
StringIO.py code does.  Until somebody adds a way to specify binary or
text mode for cStringIO objects, change the format string to use "t#"
instead of "s#", so that it will request the "text buffer" version.
This will try the default encoding for Unicode objects.

This is *not* a 2.2 bugfix (since it *is* a semantic change).

Jeremy Hylton b189b07dcc Fix SF bug #526518
The doc string for cStringIO suggested that str() of a StringIO object
was equivalent to getvalue().  This was never true, so repair the doc
string.  (doctest would have helped here.)

Bug fix candidate for any past versions.

Guido van Rossum 146483964e Patch supplied by Burton Radons for his own SF bug #487390: Modifying
type.__module__ behavior.

This adds the module name and a dot in front of the type name in every
type object initializer, except for built-in types (and those that
already had this).  Note that it touches lots of Mac modules -- I have
no way to test these but the changes look right.  Apologies if they're
not.  This also touches the weakref docs, which contains a sample type
object initializer.  It also touches the mmap test output, because the
mmap type's repr is included in that output.  It touches object.h to
put the correct description in a comment.

Guido van Rossum 2f09812efa O_cwrite(): rewrote for clarity, replacing all the (Oobject *)self
casts with a variable oself that has the proper type.  A smart
compiler may put this thing into a register.

(I'm not sure what good this does except satisfy my desire to
understand this function; I got a report about an uninitialized read
from Insure++ about this function and it hurt my eyes to even look at
it.  I gotta run away or I'll get tempted to reformat the entire
file...)

Jeremy Hylton cafd495dfe In O_writelines: Replace use of string.joinfields with "".join. 2001-02-09 23:44:22 +00:00
Jim Fulton e60de4d309 Added a new "base" type, IOobject for which most of the
operations are defined.  This will, hopefully clarify
some of the logic.

Added close test to raise proper error when operations
are performed on closed StringIOs.

Added a position argument to the truncate method.

Added a size argument to readline.

Added PyArg_Parse calls for methods that don't take arguments to
make sure they don't take arguments.
