Thomas Wouters 4d70c3d9dd Partially merge trunk into p3yk. The removal of Mac/Tools is confusing svn
merge in bad ways, so I'll have to merge that extra-carefully (probably manually.)

Merged revisions 46495-46605 via svnmerge from
svn+ssh://pythondev@svn.python.org/python/trunk

  Quality control, meet exceptions.c.

  Fix a number of problems with the need for speed code:

  One is doing this sort of thing:

      Py_DECREF(self->field);
      self->field = newval;
      Py_INCREF(self->field);

  without being very sure that self->field doesn't start with a
  value that has a __del__, because that almost certainly can lead
  to segfaults.

  As self->args is constrained to be an exact tuple we may as well
  exploit this fact consistently.  This leads to quite a lot of
  simplification (and, hey, probably better performance).

  Add some error checking in places lacking it.

  Fix some rather strange indentation in the Unicode code.

  Delete some trailing whitespace.

  More to come, I haven't fixed all the reference leaks yet...

  Quality control, meet exceptions.c, round two.

  Make some functions that should have been static static.

  Fix a bunch of refleaks by fixing the definition of
  MiddlingExtendsException.

  Remove all the __new__ implementations apart from
  BaseException_new.  Rewrite most code that needs it to cope with
  NULL fields (such code could get excercised anyway, the
  __new__-removal just makes it more likely).  This involved
  editing the code for WindowsError, which I can't test.

  This fixes all the refleaks in at least the start of a regrtest
  -R :: run.

  ("Forward-port" of r46506)

  Remove various dependencies on dictionary order in the standard library
  tests, and one (clearly an oversight, potentially critical) in the
  standard library itself - base64.py.

  Remaining open issues:
   * test_extcall is an output test, messy to make robust
   * tarfile.py has a potential bug here, but I'm not familiar
     enough with this code.  Filed in as SF bug #1496501.
   * urllib2.HTTPPasswordMgr() returns a random result if there is more
     than one matching root path.  I'm asking python-dev for
     clarification...

  PyLong_FromString():  Continued fraction analysis (explained in
  a new comment) suggests there are almost certainly large input
  integers in all non-binary input bases for which one Python digit
  too few is initally allocated to hold the final result.  Instead
  of assert-failing when that happens, allocate more space.  Alas,
  I estimate it would take a few days to find a specific such case,
  so this isn't backed up by a new test (not to mention that such
  a case may take hours to run, since conversion time is quadratic
  in the number of digits, and preliminary attempts suggested that
  the smallest such inputs contain at least a million digits).

  [Bug #1473048]
  SimpleXMLRPCServer and DocXMLRPCServer don't look at
  the path of the HTTP request at all; you can POST or
  GET from / or /RPC2 or /blahblahblah with the same results.
  Security scanners that look for /cgi-bin/phf will therefore report
  lots of vulnerabilities.

  Fix: add a .rpc_paths attribute to the SimpleXMLRPCServer class,
  and report a 404 error if the path isn't on the allowed list.

  Possibly-controversial aspect of this change: the default makes only
  '/' and '/RPC2' legal.  Maybe this will break people's applications
  (though I doubt it).  We could just set the default to an empty tuple,
  which would exactly match the current behaviour.

  Patch #1357836:

  Prevent an invalid memory read from test_coding in case the done flag is set.
  In that case, the loop isn't entered.  I wonder if rather than setting
  the done flag in the cases before the loop, if they should just exit early.

  This code looks like it should be refactored.

  Backport candidate (also the early break above if decoding_fgets fails)

  pprint functions used to sort a dict (by key) if and only if
  the output required more than one line.  "Small" dicts got
  displayed in seemingly random order (the hash-induced order
  produced by dict.__repr__).  None of this was documented.
  Now pprint functions always sort dicts by key, and the docs
  promise it.

Tim Peters e564e7f939 new_mmap_object(), Windows flavor.
On a box where sizeof(size_t) == 4, C doesn't define
what happens when a size_t value is shifted right by
32 bits, and this caused test_mmap to fail on Windows
in a debug build.  So use different code to break
the size apart depending on how large size_t actually
is.

This looks like an illusion, since lots of code in this
module still appears to assume sizes can't be more
than 32 bits (e.g., the internal _GetMapSize() still
returns an int), but at least test_mmap passes again.

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 *.

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.

Tim Peters 5ebfd36afa CVS patch #477161: New "access" keyword for mmap, from Jay T Miller.
This gives mmap() on Windows the ability to create read-only, write-
through and copy-on-write mmaps.  A new keyword argument is introduced
because the mmap() signatures diverged between Windows and Unix, so
while they (now) both support this functionality, there wasn't a way to
spell it in a common way without introducing a new spelling gimmick.
The old spellings are still accepted, so there isn't a backward-
compatibility issue here.

Tim Peters d401eddf91 Fix new compiler warnings. Also boost "start" from (C) int to long and
return a (C) long:  PyArg_ParseTuple and Py_BuildValue may not let us get
at the size_t we really want, but C int is clearly too small for a 64-bit
box, and both the start parameter and the return value should work for
large mapped files even on 32-bit boxes.  The code really needs to be
rethought from scratch (not by me, though ...).

                   the use of getpagesize(), which is deprecated and

* After discussion with Trent, all INT_PTR references have been removed in favour of the HANDLE it should always have been.  Trent can see no 64bit issues here.

* In this process, I noticed that the close operation was dangerous, in that we could end up passing bogus results to the Win32 API.  These result of the API functions passed the bogus values were never (and still are not) checked, but this is closer to "the right thing" (tm) than before.

Tested on Windows and Linux.

There is a minor style issue involved: Guido seems to have preferred English

2000-04-05 14:15:31 +00:00
Fred Drake 56a87a0905 Patch from Hrvoje Niksic <hniksic@iskon.hr>:
The bug is in mmap_read_line_method(), and its loop that searches for
newlines.  After the loop reaches EOF, eol is incremented and points
after the end of the memory.  This results in readline() method
sometimes picking up and returning a byte after the end of the string.
This is usually a bogus \0, but it could cause SIGSEGV if it's after
the end of the page).

The patch fixes the problem.  Also, it uses memchr() for finding a
character, which is in fact the "strnchr" the comment is asking for.
memchr() is already used in Python sources, so there should be no
portability problems.

The win32 specific "tag" param is now optional.  The end result is
that the exact same test suite runs on Windows (definately a worthy
goal!).

* I changed the error object.  All occurences of the error, except
for 1, corresponds to an underlying OS error.  This one was changed
to a ValueError (a better error for that condition), and the module
error object is now simply EnvironmentError.  All win32 error
routines now call the new Windows specific error handler.
