Re: [issue16500] Add an 'afterfork' module
2012/11/20 Christian Heimes rep...@bugs.python.org IFF we are going to walk the hard and rocky road of exception handling, then we are going to need at least four hooks and a register function that takres four callables as arguments: register(prepare, error, parent, child). Each prepare() call pushes an error handling onto a stack. In case of an exception in a prepare handler, the error stack is popped until all error handlers are called. This approach allows a prepare handler to actually prevent a fork() call from succeeding. FWIW, PyPy already has a notion of fork hooks: https://bitbucket.org/pypy/pypy/src/b4e4017909bac6c102fbc883ac8d2e42fa41553b/pypy/module/posix/interp_posix.py?at=default#cl-682 Various subsystems (threads cleanup, import lock, threading.local...) register their hook functions. You may want to experiment from there :-) A new atfork module would be easy to implement. -- Amaury Forgeot d'Arc ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Also, I am not going to try to convince you it is a good idea, since I have long figured out that you are against any contributions from me on some sort of principle. However, even if you cannot agree that it is a good idea, can you explain to me how it is a BAD idea? How can expanding object references to strings to all objects, using the same mechanism, be bad? How can it be bad to make the marshal format more complete with minimal effort?

[issue16475] Support object instancing and recursion in marshal
Kristján Valur Jónsson added the comment: Serhiy, to answer your questions: Can you please measure the time of unmarshalling? Sure. Normally, I wouldn't consider time to be important here because for code objects, unmarshaling is done only once per run However, testing it is simple: I added timeit(number=100) for unmarshaling of the different version code. 0.09614 0.09605 0.582672 0.553599 0.05590 0.05628 0.293370 0.285517 0.05703 0.05754 0.294601 0.292070 The lines are version 2, 3, and 4(*) respectively. The columns are test_marshal.py, recode.intern(test_marshal.py), decimal.py and recode.intern(decimal.py) As you see, loading time is almost halfed with version 3 and 4 compared to 2. Version 3 is also slightly faster than 4 (*)verion 4 is a special version that only instances strings. If you can count the statistics about marshalled types (what percent of shared and non shared integers, strings, etc), it would also be very interesting. That's more tricky, at least on a type=by-type basis, but I could do a global object count. Later. There is at least one reason. This increases size of the refs table. I checked this, by printing out the size of the instance list when loads() was done: 457 1571 297 1163 429 1539 The columns are test_marshal.py and decimal.py the lines are version 3, version 4( only strings ) and special version5 which is like 3 but omits ints. As you see, the ints correspond to roughly 6% and 2% of the instances respectively. The bulk of the list is taken up by strings (65% and 74%) This shows that adding instancing of all other types on top of the strings does not typically expand the instance list more than 50% -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16475 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue16513] SGMLParser processing tr which include two a will have problem
Ezio Melotti added the comment:
Sorry, I misread your code, looks like you want the href *without* 'cve'.
In that case change my code to use 'cve' not in attrs['href'] (also avoid
using s.find('cve') == -1 , and use the more readable and idiomatic 'cve' not
in s ).
I think your original script doesn't work for two reasons:
1) you are looking for a table with class=tablesorter, but in the HTML the
table doesn't have that class, so self.is_table is never set to True;
2) you are finding the href of the a with a style attribute and correctly
setting it to self.href_name, but the value is then replaced by when the
following a without style is found;
That said, I still suggest you to abandon sgmllib and use HTMLParser, or
possibly an external module like BeautifulSoup or LXML.

[issue16514] Cryptic traceback when sys.path[0] is None
New submission from Barry A. Warsaw: When sys.path[0] is None, attempting to import a module produces a cryptic chained traceback. This is a regression from 3.2 where the import would succeed. The basic issue is that in 3.2's import.c, non-string/bytes items on sys.path are essentially ignored (see the loop in import.c:1708 find_module()) while they are not ignored in 3.3's importlib. This means that because zipimporter.zipimiporter is by default the first thing on sys.path_hooks, zipimporter.zipimporter(None) gets called. This raises a TypeError which starts the chained exception. Note that the fact that zipimporter.zipimporter(None) raises a TypeError is *not* a regression. The regression is that None makes its way to sys.path_hooks at all. I think this will be relatively easy to fix, if we agree that the current regressive behavior is a bug. -- assignee: barry components: Interpreter Core keywords: 3.3regression messages: 175996 nosy: barry priority: high severity: normal status: open title: Cryptic traceback when sys.path[0] is None type: behavior versions: Python 3.3, Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16514 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

I think there are two main options if a prepare callback fails: 1) The fork should not occur and the exception should be raised 2) The fork should occur and the exception should be only be printed I favour option 1 since, if they want, users can always wrap their prepare callbacks with try: ... except: sys.excepthook(*sys.exc_info()) With option 1 I don't see why error callbacks are necessary. Just unwind the stack of imaginary try...finally... clauses and let any exceptions propagate out using exception chaining if necessary. This is what pure-python-atfork.patch does. Note, however, that if the fork succeeds then any subsequent exception is only printed. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16500 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue8713] multiprocessing needs option to eschew fork() under Linux
Richard Oudkerk added the comment:
http://hg.python.org/sandbox/sbt#spawn now contains support for starting
processes via a separate server process. This depends on fd passing support.
This also solves the problem of mixing threads and processes, but is much
faster than using fork+exec. It seems to be just as fast as using plain fork.
I have tested it successfully on Linux and a MacOSX buildbot. (OpenSolaris
does not seem to support fd passing.)
At the begining of your program you write
multiprocessing.set_start_method('forkserver')
to use the fork server.
Alternatively you can use
multiprocessing.set_start_method('spawn')
to use _posixsubprocess.fork_exec() with closefds=True on Unix or
multiprocessing.set_start_method('fork')
to use the standard fork method.
This branch also stops child processes on Windows from automatically inheriting
inheritable handles.
The test suite can be run with the different start methods by doing
python -m test.test_multiprocessing_fork
python -m test.test_multiprocessing_spawn
python -m test.test_multiprocessing_forkserver

Martin v. Löwis added the comment: Am 20.11.12 18:02, schrieb Antoine Pitrou: It is a bad idea because features have to be supported in the long-term, which means more maintenance effort. So, basically, this is the same reason we don't accept every feature request + patch that gets posted to the tracker. For marshal, this actually is of less concern - we are free to change it whenever we please (and people actually did change it when they pleased). Of course, there still must be a demonstrated gain, and that must be significant enough to justify the size of the change (in diffstat). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16475 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue16516] argparse types (and actions) must be hashable
New submission from Joel Nothman:
The argparse documentation states that type= can take any callable that takes
a single string argument and returns the converted value. The following is an
exception:
import argparse
ap = argparse.ArgumentParser()
ap.add_argument('foo', type={}.get)
Traceback (most recent call last):
File stdin, line 1, in module
File /usr/lib/python3/argparse.py, line 1294, in add_argument
type_func = self._registry_get('type', action.type, action.type)
File /usr/lib/python3/argparse.py, line 1236, in _registry_get
return self._registries[registry_name].get(value, default)
TypeError: unhashable type: 'dict'
Sadly, a method bound to an unhashable type is unhashable! (Of course, is
trivial to use partial or lambda to make any function hashable.)
The offending line in _registry_get is intended to look up named types (or
actions), so it perhaps only relevant for string type= and action= values,
which could be handled explicitly instead of using dict.get(x, x) to handle
both cases. Alternatively, the TypeError could be caught and default returned.

[issue16518] add buffer protocol to glossary
New submission from Chris Jerdonek: This issue is to add buffer protocol (or perhaps buffer object) to the glossary. The concept is currently described here: http://docs.python.org/dev/c-api/buffer.html#buffer-protocol Éric initially suggested doing this in the comments to issue 13538. Such a glossary entry would be useful because the buffer protocol (or buffer object) should likely be cited, for example, wherever a function accepts a bytes object, bytearray object, or any object that supports the buffer protocol. The str() constructor is one example where this is done: http://hg.python.org/cpython/file/59acd5cac8b5/Doc/library/functions.rst#l1275 Buffer object might be the more useful term to add to the glossary because it would help to have a briefer way of saying any object that supports the buffer protocol. (I'm assuming this is what buffer object actually means.) The patch for this issue should also do a comprehensive review of occurrences of buffer object/protocol throughout the docs and add or update links and index entries where appropriate. -- assignee: docs@python components: Documentation messages: 176042 nosy: chris.jerdonek, docs@python, eric.araujo, ezio.melotti, pitrou priority: normal severity: normal status: open title: add buffer protocol to glossary type: enhancement versions: Python 3.2, Python 3.3, Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16518 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue16519] site.venv() should use abspath(executable)
New submission from Christian Heimes: While I was testing #16499 I found a small bug in the venv code of the site module. The code in site.venv() doesn't use abspath() to sanitize the path to executable_dir. This leads to wrong behavior when a venv is created in the root of a hg checkout and the non-venv interpreter is called with a relative path: (venv) heimes@hamiller:~/dev/python/cpython/venv$ ../python -c import sys; print(sys.path) ['', '/usr/local/lib/python34.zip', '/home/heimes/dev/python/cpython/Lib', '/home/heimes/dev/python/cpython/Lib/plat-linux', '/home/heimes/dev/python/cpython/build/lib.linux-x86_64-3.4-pydebug', '/home/heimes/dev/python/cpython/venv/lib/python3.4/site-packages'] The fix is simple, straight forward and totally harmless: --- a/Lib/site.py +++ b/Lib/site.py @@ -484,7 +484,7 @@ executable = os.environ['__PYVENV_LAUNCHER__'] else: executable = sys.executable -executable_dir, executable_name = os.path.split(executable) +executable_dir, executable_name = os.path.split(os.path.abspath(executable)) site_prefix = os.path.dirname(executable_dir) sys._home = None if sys.platform == 'win32': -- components: Interpreter Core messages: 176043 nosy: christian.heimes priority: normal severity: normal status: open title: site.venv() should use abspath(executable) type: behavior versions: Python 3.3, Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16519 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
