[issue8514] Create fs_encode() and fs_decode() functions in os.path
STINNER Victor victor.stin...@haypocalc.com added the comment: Please follow the naming convention used in os.path. The functions would have to be called os.path.fsencode() and os.path.fsdecode(). Ok Other than that, I'm +0 on the patch: the sys.filesystemencoding logic doesn't really work well in practice - on Unix and BSD platforms, there's no such thing as a single system-wide file system Today, most POSIX system uses utf8 by default for all partitions. If you mount an USB key, CD-Rom or network shared directory with the wrong options, you may get filenames in a different encoding. But this issue is not about fixing your OS configuration, but helping the most common case: a system using the same encoding everywhere (for the whole file system). You are still free to use directly the native OS type (unicode on Windows, bytes on other OS), ie. don't use fsencode()/fsdecode(). Python3 prefers unicode, eg. print expects an unicode string, not a byte string. I mean it's more pratical to use unicode everywhere in Python, and so fsencode()/fsdecode() can be really useful on POSIX systems. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8514 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue8529] subclassing builtin class (str, unicode, list...) needs to override __getslice__
New submission from Florent Xicluna florent.xicl...@gmail.com: It looks like a bug, because __getslice__ is deprecated since 2.0. If you subclass a builtin type and override the __getitem__ method, you need to override the (deprecated) __getslice__ method too. And if you run your program with python -3, it Example script: class Upper(unicode): def __getitem__(self, index): return unicode.__getitem__(self, index).upper() #def __getslice__(self, i, j): #return self[i:j:] if __name__ == '__main__': text = Upper('Lorem ipsum') print text[:] print text[::] -- components: Interpreter Core messages: 104148 nosy: flox priority: normal severity: normal status: open title: subclassing builtin class (str, unicode, list...) needs to override __getslice__ type: behavior versions: Python 2.7 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8529 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue8530] Stringlib fastsearch can read beyond the front of an array
New submission from Alex alex.gay...@gmail.com: In Objects/stringlib/fastsearch.h the lines: if (!STRINGLIB_BLOOM(mask, s[i-1])) and if (!STRINGLIB_BLOOM(mask, s[i-1])) can read beyond the front of the array that is passed to it when the loop enters with i = 0. I originally noticed this when porting the algorithm to PyPy (which has bounds checking :)), all tests pass if I simple add `if i-1 = 0` before the conditional. This doesn't appear to actually cause the algorithm to ever break, but it is unsafe. -- messages: 104149 nosy: alex severity: normal status: open title: Stringlib fastsearch can read beyond the front of an array ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8530 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

R.

However, onerror is free to correct the problem and then call rmtree. (The danger, of course, is infinite recursion, but I don't think it is our responsibility to protect the author of an onerror handler from that potential mistake.) By analogy to the other place rmtree returns after an onerror call, the above fix does fix a real bug, regardless of the disposition of the feature request, since currently if onerror returns we get a name error. -- components: +Library (Lib) -Extension Modules keywords: +easy nosy: +r.david.murray priority: - low stage: - unit test needed type: - behavior versions: +Python 2.6, Python 2.7, Python 3.1, Python 3.2 -Python 2.5 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8523 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue8532] Refinements to Python 3 New GIL
New submission from David Beazley d...@dabeaz.com: The attached patch makes two simple refinements to the new GIL implemented in Python 3.2. Each is briefly described below. 1. Changed mechanism for thread time expiration In the current implementation, threads perform a timed-wait on a condition variable. If time expires and no thread switches have occurred, the currently running thread is forced to drop the GIL. In the patch, timeouts are now performed by a special GIL monitor thread. This thread runs independently of Python and simply handles time expiration. Basically, it records the number of thread switches, sleeps for a specified interval (5ms), and then looks at the number of thread switches again. If no switches occurred, it forces the currently running thread to drop the GIL. With this monitor thread, it is no longer necessary to perform any timed condition variable waits. This approach has a few subtle benefits. First, threads no longer sit in a wait/timeout cycle when trying to get the GIL (so, there is less overhead). Second, you get FIFO scheduling of threads. When time expires, the thread that has been waiting the longest on the condition variable runs next. Generally, you want this. 2. A very simple two-level priority mechanism A new attribute 'cpu_bound' is added to the PyThreadState structure. If a thread is ever forced to drop the GIL, this attribute is simply set True (1). If a thread gives up the GIL voluntarily, it is set back to False (0). This attribute is used to set up simple scheduling (described next). There are now two separate condition variables (gil_cpu_cond) and (gil_io_cond) that separate waiting threads according to their cpu_bound attribute setting. CPU-bound threads wait on gil_cpu_cond whereas I/O-bound threads wait on gil_io_cond. Using the two condition variables, the following scheduling rules are enforced: - If there are any waiting I/O bound threads, they are always signaled first, before any CPU-bound threads. - If an I/O bound thread wants the GIL, but a CPU-bound thread is running, the CPU-bound thread is immediately forced to drop the GIL. - If a CPU-bound thread wants the GIL, but another CPU-bound thread is running, the running thread is immediately forced to drop the GIL if its time period has already expired. Results --- This patch gives excellent results for both the ccbench test and all of my previous I/O bound tests.

There's a couple of fixes for do_handshake there (including timeout issues). -- nosy: +pitrou priority: - normal versions: +Python 3.1, Python 3.2 -Python 3.0 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4171 ___ -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4171 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue7946] Convoy effect with I/O bound threads and New GIL
Gregory P. Smith g...@krypto.org added the comment: Nice dabeaz. One potential concern with dabeaz_gil.patch 2010-04-25 21:13 is that it appears to always leave the gil_monitor thread running. This is bad on mobile/embedded platforms where waking up at regular intervals prevents advanced sleep states and wastes power/battery. (practical example: the OLPC project has run into this issue in other code in the past) Could this be modified so that gil_monitor stops looping (blocks) so long as there are only IO bound Python threads running or while no python thread owns the GIL? In that situation a multithreaded python process that has either reverted to one thread or has all threads blocked in IO would be truly idle rather than leaving the gil_monitor polling. -- nosy: +gregory.p.smith ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7946 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue8514] Create fsencode() and fsdecode() functions in os.path
Gregory P. Smith g...@krypto.org added the comment: i'm +0.7 on fsencode/fsdecode going into os.path. My bikeshed 0.7? They're also useful for dealing with environment variables which are not strictly filesystem (fs) related but also suffer from the same issue requiring surrogate escape. But other than just calling these os.encode and os.decode I don't have any brilliant alternate naming suggestions. thoughts? I could easily live with os.path.fsencode/fsdecode, I just wanted to point the other use out. -- nosy: +gregory.p.smith ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8514 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
