[issue18309] Make python slightly more relocatable
Mathias Fröhlich added the comment: Hi Ronald, Eric, Nick, Looking up the symbol name of the current function should work also. And I am free to rename these functions to whatever you like. Attached is version 2 of the patch with the suggested changes. The windows implementation is still untested. It would be interesting to know if this kind of lookup scheme can be included into PEP 432. Provided the spirit of this PEP, I can imagine to provide several functions to build up the pythonpath starting from something. So say, have a 'get python path from argv[0]', a 'get python path from shared python library' and a 'get python path from prefix' function (I may miss a variant). Also a 'build python path from python home root entry point' function would be useful and could be used by the above functions. An application embedding python can then call those functions that are sensible for its own use and installation scheme to set the module path in the PyConfig struct. The Py_ReadConfig function will internally use the above suggested functions to build up the default configuration if not already provided.

[issue18305] [patch] Fast sum() for non-numbers
Sergey added the comment: This patch implements another solution to the same bug. But instead of changing default code it adds a special case optimization for lists, tuples and strings, similar to those two special cases for numbers, that are already there. === Lists === No patch: $ ./python -mtimeit --setup=x=[[1,2,3]]*1 sum(x,[]) 10 loops, best of 3: 885 msec per loop fastsum.patch: $ ./python -mtimeit --setup=x=[[1,2,3]]*1 sum(x,[]) 1000 loops, best of 3: 524 usec per loop fastsum-special.patch: $ ./python -mtimeit --setup=x=[[1,2,3]]*1 sum(x,[]) 1000 loops, best of 3: 298 usec per loop Result: 3000 times faster. === Tuples === No patch: $ ./python -mtimeit --setup=x=[(1,2,3)]*1 sum(x,()) 10 loops, best of 3: 585 msec per loop fastsum.patch: $ ./python -mtimeit --setup=x=[(1,2,3)]*1 sum(x,()) 10 loops, best of 3: 585 msec per loop fastsum-special.patch: $ ./python -mtimeit --setup=x=[(1,2,3)]*1 sum(x,()) 1000 loops, best of 3: 536 usec per loop Result: 1000 times faster. === Strings === No patch (just string check removed): $ ./python -mtimeit --setup=x=['abc']*10 sum(x,'') 10 loops, best of 3: 1.52 sec per loop fastsum.patch (+ string check removed): $ ./python -mtimeit --setup=x=['abc']*10 sum(x,'') 10 loops, best of 3: 1.52 sec per loop fastsum-special.patch $ ./python -mtimeit --setup=x=['abc']*10 sum(x,'') 10 loops, best of 3: 27.8 msec per loop join: $ ./python -mtimeit --setup=x=['abc']*10 ''.join(x) 1000 loops, best of 3: 1.66 msec per loop Result: 50 times faster, but still constantly slower than join. NB: The string part of this patch is a Proof-of-Concept, just for tests, to demonstrate, that sum can really be O(n) for strings. It was written for python 2.7.5, won't work for python3, and is not expected to be applied to python2, as it changes the behavior of sum, allowing it to sum strings. But! If string part is stripped from the patch it works for both python2 and python3, and does not change existing behavior, except making sum faster. -- Added file: http://bugs.python.org/file30769/fastsum-special.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18305 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue18329] for line in socket.makefile() speed degradation
Christian Heimes added the comment: I first suspected that file based IO involves too many syscalls and context switches. However ``strace -c`` showed only minor differences in the amount of syscalls. The difference between read() and recvfrom() should not make any difference. perf revealed that the makefile() test uses much more CPU cycles. A quick check with python3.3 -m profile points to Python method call overhead. Five methods are called more than 122,000 times each and a couple of attributes are checked, too. Perhaps we can optimize away _checkReadable() and _checkClosed()? I think I know what's going on here. For socket IO readline() uses a readahead buffer size of 1. For each char a cascade of Python functions is called. os.fdopen() uses a default buffering of 4096 (or more) so it's not affected. -- Added file: http://bugs.python.org/file30770/perf.txt ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18329 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

COUNT = 100 LINELEN = 1000 int(LINELEN * COUNT / 8192) 122070 The number looks familiar, doesn't it? :) I still stand by my analysis that the slow down is caused by Python's method call overhead and the extra function call to _checkReadable(), readable and _checkClosed(). A C implementation of the raw SocketIO class would reduce the overhead. The implementation of SocketIO assumes that performance is dominated by IO (e.g. slow internet connection).

[issue18329] for line in socket.makefile() speed degradation
STINNER Victor added the comment: On Python 2, socket.makefile(rb) duplicates the file descriptor and creates a new file object: fileobj.read() calls the C function read(). On Python 3, socket.makefile(rb) creates a SocketIO wrapped in BufferedReader: fileobj.read() calls the C function recv() (recvfrom() syscall). For a UNIX socket, read() is maybe more efficient than recv(). -- nosy: +haypo ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18329 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Readline on TCP is much faster on Python 3.4 than 2.7: 788.4 MB/s vs 234.9 MB/s (3.4x faster). I don't know why, but I don't want to investigate (it is not a regression) :-) The slowdown on other readline tests are less interesting: Python 3.4 is 16% slower for TCP mode, fdopen method and 20% slower for UNIX mode, fdopen method. It would be interesting to have the same benchmark implemented in C to compare raw performances, so it would be possible to measure the overhead of Python. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18329 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue18279] IDLE Unit test for RstripExtension.py
Terry J. Reedy added the comment: I want to make two separate commits. First add mock Text into mock_tk.py, and add a new test_text.py. I suggested looking at the tkinter Text test. I turns out that it only tests a few special search cases. I am guessing that they have something to do with the tkinter interface. If neither you nor Todd feel like writing the Text test, I will. Let me know either way. Second, add the new mock_idle and test_rstrip files. For the latter, at least one line should have no whitespace, and one should have an indent. With an indent, the test would fail if rstrip in the tested file were changed to strip. In the tearDown method, the apparent purpose of self.rstripextension = None is to actually do del self.rstripextension and that happens automatically when self disappears. With a mock editor window, there is no need for root.destroy and hence for the close call, and hence for the tearDown method. With only one test method, the setUp lines can be part of the test. For the attribute names, I strongly prefer 'rstrip' to 'rstripExtension' and 'editor' to 'mockEditorWindow'. I am curious about this comment: # Note: Tkinter always adds a newline at the end of the text widget, # hence the newline in the expected_text string In live Idle, I tried 'strip trailing whitespace' with text that did not end with \n and there was none visible after. An annoyance is that after stripping the filename is prefixed with * to indicate that it has been changed and needs to be changed, even when it has not (or should not have been). Closing brings up the unnecessary 'Changed, save?' box. Is this related to the comment? -- stage: - patch review ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18279 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
