[issue14059] Implement multiprocessing.Barrier

[Charles-François Natali]

Charles-François Natali  added the comment:

> Here is an initial implementation.

Wouldn't it be simpler with a mp.Condition?

Otherwise, this should be added to Lib/multiprocesing.synchronize.py, and the 
tests to test_multiprocessing.

[issue14060] Implement a CSP-style channel

[Matt Joiner]

Matt Joiner  added the comment:

As I see it, here are the desirable features of CSP-style concurrency as it 
pertains to channels:

1) At least an unbuffered mode
2) Can be marked closed
3) Block on multiple send/receives until one can proceed

Specifically features 1 and 2 could be bolted onto queue.Queue with excellent 
backward compatibility with existing usage of Queue. As mentioned on the 
mailing list, maxsize=None would mean infinite queue, and maxsize=0 would 
become the unbuffered mode Currently maxsize<=0 means infinite. Existing code 
that assumed one or the other and explicitly created Queues this way would have 
to change (I'd suspect almost no code would be affected).

Feature 3 allows for all the awesomeness of CSP channels, but I think it 
requires a redesign under the covers of Queue to allow waiters to be woken from 
arbitrary Queues to which they are subscribed. The synchronization internals 
are quite complex.

There appears to be several ways to proceed:

1) Add unbuffered mode, closing, and other syntactical sugar to queue.Queue.
2) Do (1) and additionally rework the internals to allow blocking on on several 
Queue actions at once.
3) Add an unbuffered-only, closable threading.Channel for use with higher level 
primitives (as Guido suggested).
4) Make no changes to queue, and create a brand-new module with full blown CSP 
channels.

[issue14071] allow more than one hash seed per process (move _Py_HashSecret into PyInterpreterState)

[Gregory P. Smith]

New submission from Gregory P. Smith :

The newly added hash randomization seed (issue 13703) is a global defined in 
object/object.c that is initialized only once within a process by a call from 
Py_InitializeEx().

For applications embedding Python interpreters it may be useful for them to NOT 
share a hash randomization seed across all interpreter instances within that 
process.  That way long living processes or processes serving many independent 
tasks can avoid using the same hash seed for separate tasks.

[issue13703] Hash collision security issue

[Georg Brandl]

Georg Brandl  added the comment:

That is a good question.  I don't really care either way, but let's say +0 for 
turning it off when seed == 0.

-R still needs to be made default in 3.3 - that's one reason this issue is 
still open.

[issue13703] Hash collision security issue

[Gregory P. Smith]

Gregory P. Smith  added the comment:

Question: Should sys.flags.hash_randomization be True (1) when 
PYTHONHASHSEED=0?  It is now.

Saying yes "working as intended" is fine by me.

sys.flags.hash_randomization seems to simply indicate that doing something with 
the hash seed was explicitly specified as opposed to defaulting to off, not 
that the hash seed was actually chosen randomly.

What this implies for 3.3 after we make hash randomization default to on is 
that sys.flags.hash_randomization will always be 1.

[issue13703] Hash collision security issue

[Gregory P. Smith]

Gregory P. Smith  added the comment:

The bug report is the easiest thing to search for and follow when checking when 
something is resolved so it is nice to have a link to the relevant patch(es) 
for each branch.  I just wanted to note the major commit here so that all 
planned branches had a note recorded.  I don't care that it wasn't automatic. :)

For observers: There have been several more commits related to fixing this 
(test dict/set order fixes, bug/typo/merge oops fixes for the linked to 
patches, etc). Anyone interested in seeing the full list of diffs should look 
at their specific branch on our around the time of the linked to changelists.  
Too many to list here.

[issue13641] decoding functions in the base64 module could accept unicode strings

[Guido van Rossum]

Guido van Rossum  added the comment:

Aside: I, too, at first thought this would be a bad idea because it brings back 
the Python 2 issue of accepting some but not all Unicode strings. But then I 
realized that by their nature these functions only accepts a very specific set 
of characters -- so the restriction to (a subset of) ASCII is intrinsic to the 
functionality, and there is no possibility of confusion. If anything, accepting 
bytes is more likely to be confusing (they could be EBCDIC! :-). So no 
objection here. And a slight preference for ValueError.

[Nick Coghlan]

Nick Coghlan  added the comment:

FWIW, I doubt you'd get many objections if you ended up wanting to make time a 
builtin module and inject it into the bootstrapping namespace.

While I don't think the delay in noticing filesystem changes is reasonable as 
the default behaviour, it might be interesting to see how tricky it would be to 
create a custom importer (for either meta_path or path_hooks) that did this.

When developing Python code, I often find myself needing to run "rm *.pyc" so 
that the interpreter will ignore any new changes that I have made to source 
files. It's really frustrating when forgotten.

Adding a flag to the reload builtin would go a long way to simplify this 
process.

[issue2661] Mapping tests cannot be passed by user implementations

[Éric Araujo]

Éric Araujo  added the comment:

I think it would be great to test the stdlib’s mapping classes against common 
tests; there is a patch to add more MutableMapping methods to dbm classes for 
example, and it was not trivial to get good test coverage.

Not sure about the status of the module though, i.e. if we should officially 
support people using mapping_tests to check their code; it would be very useful 
for classes that don’t inherit from an ABC, but the whole test package is not 
intended for public use.

[issue5411] Add xz support to shutil

[Éric Araujo]

Éric Araujo  added the comment:

Note that there is a way to get fully automated support for tar formats: 
tarfile could expose, in addition to the list compression_formats, another 
structure with the descriptions (e.g. “gzip’ed tar file”) and file extensions 
(e.g. ['.gz', '.tgz'] —no, it’s not '.tar.gz', which is unfortunate, and could 
cause Lars to reject that idea).  I’m just putting this here for reference, but 
my preference is still for the second idea I talk about in my precedent message.

[issue5411] Add xz support to shutil

[Éric Araujo]

Éric Araujo  added the comment:

I have a working updated shutil module, tests pass and the documentation is 
improved.  I will make sure to make different commits for improving the tests, 
cleaning up some things, adding tarfile.compression_formats and removing 
duplication in shutil (see dep bugs), to be sure not to introduce regressions.

Before I finish and post the patch, I’d like feedback on a choice I made.  I 
don’t think it’s possible to have shutil automatically support all the formats 
that tarfile does, because of the spelling issue I mentioned.  Here’s what the 
code would look like (let me know if I should post it elsewhere or as a file to 
let you get syntax coloring):
  
  _ARCHIVE_FORMATS = {}
  _UNPACK_FORMATS = {}

  for fmt in tarfile.compression_formats:
  code = fmt + 'tar'
  ext = '.' + fmt
  desc = "%s'ed tar file" % fmt
  _ARCHIVE_FORMATS[code] = (_make_tarball, [('compress', fmt)], desc)
  _UNPACK_FORMATS[code] = ([ext], _unpack_tarfile, [], desc)

  # kludge to add alternate extension
  if 'gztar' in _ARCHIVE_FORMATS:
  _UNPACK_FORMATS['gztar'][0].append('.tgz')
  # XXX desc should say "gzip'ed tar file", not "gz'ed"

  # rectify naming incompatibility
  if 'bz2tar' in _ARCHIVE_FORMATS:
  # XXX alternative: make 'bztar' alias for 'bz2tar', but would complicate
  # manipulating the registries
  del _ARCHIVE_FORMATS['bz2tar']
  del _UNPACK_FORMATS['bz2tar']
  desc = "bzip2'ed tar file"
  _ARCHIVE_FORMATS['bztar'] = (_make_tarball, [('compress', 'bz2')], desc)
  _UNPACK_FORMATS['bztar'] = (['.bz2'], _unpack_tarfile, [], desc)

  # now add uncompressed tar and zip file

I really don’t like that code.  Given that tarfile is not extensible at run 
time, it is not a big deal to have to update shutil whenever we add a 
compression format to tarfile.  Therefore, I backtracked on my “automatic 
support” idea but kept a lot of cleanup in did in the code.  Here’s what the 
code looks like:

  _ARCHIVE_FORMATS = {}
  _UNPACK_FORMATS = {}

  if 'xz' in tarfile.compression_formats:
  desc = "xz'ed tar file"
  # XXX '.xz' is not great, '.tar.xz' would be better
  _ARCHIVE_FORMATS['xztar'] = (_make_tarball, [('compress', 'xz')], desc)
  _UNPACK_FORMATS['xztar'] = (['.xz'], _unpack_tarfile, [], desc)

  if 'bz2' in tarfile.compression_formats:
  desc = "bzip2'ed tar file"
  _ARCHIVE_FORMATS['bztar'] = (_make_tarball, [('compress', 'bz2')], desc)
  _UNPACK_FORMATS['bztar'] = (['.bz2'], _unpack_tarfile, [], desc)

  if 'gz' in tarfile.compression_formats:
  desc = "gzip'ed tar file"
  _ARCHIVE_FORMATS['gztar'] = (_make_tarball, [('compress', 'gz')], desc)
  _UNPACK_FORMATS['gztar'] = (['.gz', '.tgz'], _unpack_tarfile, [], desc)

So, do you agree that “not automated but not ugly” is better than “automated 
with ugly klutches”?

It's not ignored, it raises ValueError. Since the common case it to feed
valid (not invalid) baseXX data to these functions, that's a very benign

[issue13964] os.utimensat() and os.futimes() should accept Decimal, drop os.futimens()

[STINNER Victor]

STINNER Victor  added the comment:

Here is a first step: add _PyTime_ObjectToTimespec() to pytime.h and use it for 
signal.sigtimedwait().

signal.sigtimedwait(sigwait, (timeout_sec, timeout_nsec)) becomes 
signal.sigtimedwait(sigwait, timeout).

I chose pytime.h instead of timefuncs.h because I plan to use 
_PyTime_ObjectToTimespec() in the posix module. I don't want to have a copy of 
this function in each module: timefuncs.h requires to compile the module with 
_time.c.

[issue14053] Make Tools/scripts/patchcheck.py compatible with mercurial mqueues.

[Nadeem Vawda]

Nadeem Vawda  added the comment:

Hmm... it looks like mq_changed_files() duplicates a chunk of logic from
the existing changed_files() code. You can get rid of this redundancy by
replacing mq_changed_files() with a function that checks for applied MQ
patches; let's call it mq_patches_applied(). Then you can say:

if mq_patches_applied():
cmd += ' --rev qparent'

before the call to Popen in changed_files(), and leave the rest of the
function unmodified. The basic logic that the code will follow is this:

if :
return files listed by 'hg status --added --modified --no-status --rev 
qparent'
else:
return files listed by 'hg status --added --modified --no-status'


The mq_patches_applied() function can be implemented by running
'hg qapplied' and checking whether it (a) prints at least one patch name,
(b) prints out nothing, or (c) gives an error.

[issue14053] Make Tools/scripts/patchcheck.py compatible with mercurial mqueues.

[Francisco Martín Brugué]

Francisco Martín Brugué  added the comment:

The patch is updated. Notice about:
[...]Ideally, it
  should distinguish between this and other errors by checking the
  subprocess's stderr, so that if a different error occurs, we can still
  print out the error message.
[…]
that should be improved as now stderr is ignored in 'mq_changed_files'
(user case: 'no mq extension enabled'). Suggestions are welcome!

> [..] but this is a bit orthogonal.
IMHO the MQ feature works very well for pydev newbies (as I'm) and it's
a good recommendation (it's a taste thing ...)

> The easiest thing to do is to make some changes and use
> "hg diff>  patch.diff" and the devguide should advertise this IMHO.  This 
> also works fine with `make patchcheck`.

There is some small differences between diff, qdiff and status but if one uses 
MQ then diff isn't enough. One really wants to know the changes from qparent to 
qtip and using 'status' as proposed I thing that it's the best solution.

Cheers,
francis

[issue14066] Crash in imputil.imp.find_module when a *directory* exists with the given name due to double-close of FILE*

[Dave Malcolm]

New submission from Dave Malcolm :

$ mkdir some_directory_ending_with_a.py
$ python -c "import imputil; 
imputil.imp.find_module('some_directory_ending_with_a')"
*** glibc detected *** python: double free or corruption (!prev): 
0x01589bf0 ***
Aborted

What's happening is that call_find_module opens fp, and tries to create a 
PyFileObject from it:

  2844 if (fp != NULL) {
>>2845 fob = PyFile_FromFile(fp, pathname, fdp->mode, fclose);
  2846 if (fob == NULL) {
  2847 fclose(fp);
  2848 return NULL;
  2849 }
  2850 }

The call fails at the very end of fill_file_fields() inside the call to 
dircheck() here:
   180  f->f_fp = fp;
   181  f = dircheck(f);
   182  return (PyObject *) f;
   183  }
   184  

but f->fp == fp

Hence when fill_file_fields returns NULL, and f is cleaned up here:
   484  if (fill_file_fields(f, fp, o_name, mode, close) == NULL) {
>> 485  Py_DECREF(f);
   486  Py_DECREF(o_name);
   487  return NULL;
   488  }

then f->fp is closed within file_dealloc()

Then, when PyFile_FromFile returns NULL, call_find_module calls fclose(fp):
  2844 if (fp != NULL) {
  2845 fob = PyFile_FromFile(fp, pathname, fdp->mode, fclose);
  2846 if (fob == NULL) {
>>2847 fclose(fp);
  2848 return NULL;
  2849 }
  2850 }

and it attempts to close fp for the second time.

The documentation for PyFile_FromFile:
  http://docs.python.org/c-api/file.html#PyFile_FromFile
says:
"Return NULL and close the file using close on failure".

It therefore looks like call_find_module's fclose(fp) is incorrect here, and is 
what leads to the double-free.

[issue14052] importlib mixes up '.' and os.getcwd()

[Brett Cannon]

Brett Cannon  added the comment:

The test suite does use importlib for some imports as finders from importlib 
for some packages stick around. I brought this up a way back but people thought 
it was actually a good idea to let importlib handle imports to stress test it.

Anyway, if it can't be reproduced then I don't think this is worth worrying 
about. As Nick pointed out, everything should be absolute anyway.

Nice feedback !

One question :

>An alternative approach that solves all three of these problems is to
>check whether we have any patches applied (using "hg qapplied"), and if
>this is the case, then add "--rev qbase" to the "hg status" command

Shouldn't be --rev qparent ? with --rev qbase the first MQ patch applied 
changes are not listed ... (one wants the changes between
qparent and qtip)

[issue14059] Implement multiprocessing.Barrier

[sbt]

sbt  added the comment:

Here is an initial implementation.  Differences from threading.Barrier:

- I have not implemented reset().

- wait() returns 0 or -1.  One thread returns 0, the remainder return -1.
  This is different to threading.Barrier where each of the N threads 
  returns a unique index in range(N).

- I added an "action_args" parameter to the constructor.  This is a tuple 
  which provides argument to the "action" callback.  (This is because closures
  are not picklable, making no-argument callbacks rather limiting for 
  multiprocessing.)

[issue14065] Element should support cyclic GC

[Martin v . Löwis]

New submission from Martin v. Löwis :

The C implementation of xml.etree.ElementTree.Element needs to support cyclic 
GC. The attached script demonstrates the lack to support that: in 3.2, the 
script passes; in 3.3 (7697223df6df) it fails with an AssertionError as the 
cycle was not cleared. 

This is an incompatible change from 3.2.

[issue6884] Impossible to include file in sdist that starts with 'build' on Win32

[Nadeem Vawda]

Nadeem Vawda  added the comment:

> (2.7.2 doesn’t include neither Antoine’s changeset nor mine, right?)

Correct; it dates back to June last year, before issue 13193 was filed.


> Can you reproduce the “include buildout.cfg” bug too?

Yes, that problem is present in 2.7.2, but not in the current revision of
the 2.7 branch. In 2.7.2, the offending regex is r'^build\.*' (since
translate_pattern() uses os.path.join, and doesn't escape the separator),
whereas in 2.7-head the regex is r'^build/.*' (using a hardcoded "/").
2.7-head with your patch applied gives r'^build\\.*' (the correct value).

In this case (unlike #9691 and #14004), the problem was fixed by the
changes in issue 13193, since the offending code is in the
"if prefix is not None:" codepath of translate_pattern(), rather than in
glob_to_re().


While we're talking about translate_pattern(), I have a question about
this line:

pattern_re = "^%s/.*%s" % (prefix_re, pattern_re)

It seems that if you specify both a prefix and a (nonempty) pattern, the
resulting regexp is something like "/.*", using the
pattern argument as a suffix. Is this the intended behavior? I would have
expected something like "/(.*/)?", defaulting to
"/.*" if pattern is empty. For example, it seems wrong that
"recursive-include foo bar.*" matches foo/test_bar.py.
