Guido van Rossum 2db4f47fdd Patch by Jason Trowbridge. (Followup to his PR#110.) (Slightly
reformatted.)

- Illegal padding is now ignored.  (Recommendation by GvR.)

- Padding no longer removes characters from data string (resulting in
lost data/strings with negative lengths).

- Illegal characters outside the ASCII range are now ignored, instead
of possibly being remapped to a valid character.

Guido van Rossum d5753e15e2 John DuBois tells us that SCO OpenServer 5.0 and later requires _SVID3
before it reveals the needed definitions in sys/statvfs.h.

Fred Drake 2a6875e172 parser__pickler(): Don't drop the third argument to
parser_ast2tuple().  Create an temporary empty dictionary to
        use.  Bug reported by Mark Favas <m.favas@per.dem.csiro.au>.

Fix a couple of comments.

Guido van Rossum 9376b74c42 (1) On Linux, we really need to trust the configure script to select
the right variant of gethostbyname_r for us, since not all Linuxes are
equal in this respect.  Reported by Laurent Pointal.

(2) On BeOS, Chris Herborth reports that instead of arpa/inet.h you
must include net/netdb.h to get the inet_ntoa() and inet_addr()
prototypes.
1999-09-15 22:01:40 +00:00
Guido van Rossum a2e48552d2 It appears that inet_aton() doesn't really exist except in libresolv;
the proper function to call is inet_addr().  Since we already had code
to do that (for MS-Windows), this simplifies things a lot!

Fred Drake 7a15ba595a Added keyword parameter support to all public interfaces; keyword
names match the documentation.

Removed broken code that supports the __methods__ attribute on ast
objects; the right magic was added to Py_FindMethod() since this was
originally written.  <ast-object>.__methods__ now works, so dir() and
rlcompleter are happy.

Fred Drake 762e206706 posix_putenv(): Constrain memory leakage when setting the same

Guido van Rossum 6a619f44c5 It turns out that modifying the environment strings is not safe.
Treat them as read-only, and make a copy as appropriately.  This was
first reported by Bill Janssend and later by Craig Rowland and Ron
Sedlmeyer.  This fix is mine.

Guido van Rossum 2f80d96c04 Patch by Stephen Turner, who writes:
"""
It fixes a memory corruption error resulting from BadPickleGet
exceptions in load_get, load_binget and load_long_binget.  This was
initially reported on c.l.py as a problem with Cookie.py; see the thread
titled "python core dump (SIGBUS) on Solaris" for more details.

If PyDict_GetItem(self->memo, py_key) call failed, then py_key was being
Py_DECREF'd out of existence before call was made to
PyErr_SetObject(BadPickleGet, py_key).

The bug can be duplicated as follows:

import cPickle
cPickle.loads('garyp')

This raises a BadPickleGet exception whose value is a freed object.  A
core dump will soon follow.
"""

Jim Fulton approves of the patch.

Guido van Rossum 9068da4b6d Milton L. Hankin reports that on Windows it is possible to have two
different values in the environ dict with the same key (although he
couldn't explain exactly how this came to be).  Since getenv() uses
the first one, Python should do too. (Some doubts about case
sensitivity, but for now this at least seems the right thing to do
regardless of platform.)

Guido van Rossum c03158bfc7 Jim Fulton writes:
I've updated cPickle.c to use class exceptions:

Changed pickle error types to classes:

  PickleError
     PicklingError
        UnpickleableError
     UnpicklingError

And change the handling of unpickleable objects so that an UnpickleableError
is raised with the unpickleable object as the argument.  UnpickleableError
has a reasonable string representation and provides access to the problem
object, which is useful during debugging.

[I'm still waiting for patches to do the same to pickle.py.]

Barry Warsaw f63b8cc07c posix_listdir(): When an error occurs, call
posix_error_with_filename() instead of posix_error(), passing in the
name argument, so you get information on which directory was being
listed.

Guido van Rossum ea424e19f1 Apparently __GNU_LIBRARY__ is defined for glibc as well as for libc5.
The test really wanted to distinguish between the two.  So now we test
for __GLIBC__ instead.  I have confirmed that this works for glibc and
I have an email from Christian Tanzer confirming that it works for
libc5, so it should be fine.

Guido van Rossum 1b9e0aae6e Jim Fulton writes:
I have attached a new cPickle that adds a new control attribute
to unpicklers:

  Added new Unpickler attribute, find_global.  If set to None, then
  global and instance pickles are disabled.  Otherwise, it should be set to
  a callable object that takes two arguments, a module name and an
  object name, and returns an object.  If the attribute is unset, then
  the default mechanism is used.

  This feature provides an additional mechanism for controlling which
  classes can be used for unpickling.

Guido van Rossum 7a1229991d Put back __osf__ support for gethostbyname_r(); the real bug was that
it was being used even without threads.  This of course might be an
all-platform problem so now we only use the _r variant when we are
using threads.

Guido van Rossum b729a1d0a8 Patch by Andrew Kuchling to unflush() (flush() for deflating).
Without this, if inflate() returned Z_BUF_ERROR asking for more output
space, we would report the error; now, we increase the buffer size and
try again, just as for Z_OK.

Guido van Rossum 57731607c3 Chris Lawrence writes:
"""
The GNU folks, in their infinite wisdom, have decided not to implement
altzone in libc6; this would not be horrible, except that timezone
(which is implemented) includes the current DST setting (i.e. timezone
for Central is 18000 in summer and 21600 in winter).  So Python's
timezone and altzone variables aren't set correctly during DST.

Here's a patch relative to 1.5.2b2 that (a) makes timezone and altzone
show the "right" thing on Linux (by using the tm_gmtoff stuff
available in BSD, which is how the GLIBC manual claims things should
be done) and (b) should cope with the southern hemisphere.  In pursuit
of (b), I also took the liberty of renaming the "summer" and "winter"
variables to "july" and "jan".  This patch should also make certain
time calculations on Linux actually work right (like the tz-aware
functions in the rfc822 module).

(It's hard to find DST that's currently being used in the southern
hemisphere; I tested using Africa/Windhoek.)

Andrew M. Kuchling b95227db4f Add an .unused_data attribute to decompressor objects. If .unused_data
is not an empty string, this means that you have arrived at the

whatever follows the compressed stream.

Guido van Rossum e7de2061b4 Implement two suggestions by Jonathan Giddy: (1) in AIX, clear the
data struct before calling gethostby{name,addr}_r(); (2) ignore the
3/5/6 args determinations made by the configure script and switch on
platform identifiers instead:

AIX, OSF have 3 args
Sun, SGI have 5 args
Linux has 6 args

On all other platforms, undef HAVE_GETHOSTBYNAME_R altogether.

1999-03-23 19:00:55 +00:00
Guido van Rossum 3baaa1375b Clean up pass for the previous patches.
- Use HAVE_GETHOSTBYNAME_R_6_ARG instead of testing for Linux and
glibc2.

- If gethostbyname takes 3 args, undefine HAVE_GETHOSTBYNAME_R --
don't know what code should be used.

- New symbol USE_GETHOSTBYNAME_LOCK defined iff the lock should be used.

- Modify the gethostbyaddr() code to also hold on to the lock until
after it is safe to release, overlapping with the Python lock.

(Note: I think that it could in theory be possible that Python code
executed while gethostbyname_lock is held could attempt to reacquire
the lock -- e.g. in a signal handler or destructor.  I will simply say
"don't do that then.")

Guido van Rossum 955becc3d9 Jonathan Giddy writes:
Here's a patch to fix the race condition, which wasn't fixed by Rob's
patch.  It holds the gethostbyname lock until the results are copied out,
which means that this lock and the Python global lock are held at the same
time.  This shouldn't be a problem as long as the gethostbyname lock is
always acquired when the global lock is not held.
