[issue14961] map() and filter() methods for iterators
Robert Lehmann lehman...@gmail.com added the comment: Your proposal seems two-fold: (a) make map/filter lazy and (b) have them as methods instead of functions. It seems Tim borrowed Guido's time machine and already implemented (a) in Python 3.x, see http://docs.python.org/py3k/library/functions.html#map and http://docs.python.org/py3k/library/functions.html#filter. Your second proposal-- which is better suited for python-ideas, really --is obstructed by iterators being merely a protocol (the next/__next__ method) which makes it hard to add those methods to one particular type. (This very discussion pops up every so often for str.join too.)

[issue13435] Copybutton does not hide tracebacks
New submission from Robert Lehmann lehman...@gmail.com: The recently added copybutton.js (r18bbfed9aafa) does not work with the 2.7 docs since they are deployed with JQuery 1.2 (which is shipped with Sphinx 0.6). Copybutton is an unobtrusive Javascript feature which adds a little button to all doctests that removes the interactive prompts in order to copy the code as-is into Python scripts. I think that feature could well be ported to Sphinx itself. In line 44 and 51 of Doc/tools/sphinxext/static/copybutton.js the code uses jQuery.nextUntil(), which is new in JQuery 1.4. That results in tracebacks being only partially hidden. Reproduce the error at http://docs.python.org/tutorial/errors.html#exceptions for example. The Python 3.2+ documentation is not affected as it is built with Sphinx 1.0, which ships with JQuery 1.4. JQuery Untils are available as a separate plugin (http://benalman.com/projects/jquery-untils-plugin/). -- assignee: docs@python components: Documentation messages: 147962 nosy: docs@python, ezio.melotti, lehmannro priority: normal severity: normal status: open title: Copybutton does not hide tracebacks type: behavior versions: Python 2.7 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13435 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue10576] Add a progress callback to gcmodule
Robert Lehmann lehman...@gmail.com added the comment: A few issues I'd like to raise: (1) Multiple callback chains. Is there any code in your existing use case of GC callbacks where you don't check for the phase argument and follow different code paths depending on it? If not, having two callback chains should be fine and takes the burden from the programmer to the implementors. (This is feasible if we *only ever* have two values for the phase.) (2) Single collections. Currently, neither PyGC_Collect nor gc.collect() invoke the callbacks (since they do not call collect_generations). Is this an oversight or intentional? (3) Error checking. What about callbacks which are bound to fail on each and every invocation, ie. because of wrong signatures. Should these be flat-out rejected in some way *on registration*, automagically removed when first encountered, or are we okay with errors slammed into the user's face every so often because he should REALLY fix them? (4) Interop. Can this be supported as easily on other VMs? (That's perhaps a good reason for the statistics to be a dict, for GCs providing vastly different amounts of information.) -- nosy: +lehmannro ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10576 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue5754] Shelve module writeback parameter does not act as advertised
Robert Lehmann lehman...@gmail.com added the comment: I think you're misquoting Python's shelve module documentation in your first sentence. The documentation says: By default modified objects are written only when assigned to the shelf [...]. If the optional writeback parameter is set to True, all entries accessed are cached in memory, and written back at close time [...]. The emphasis should be on the word only: it does *always* write to the database when assigned to the shelf but, iff writeback=True, *also* to the cache. Also consider the consequences of *only* caching keys: (a) __contains__ and has_key have to consult the dict and the cache for membership tests. (b) keys and __len__ need to compute a union of both sources. (c) __delitem__ is no longer guaranteed to fail on the cache if it failed for the database. I admit the docs could spell this out more clearly. I attached a patch ensuring the behaviour I described in a test and updating the docs. (Note: shelve is no extension module -- it's part of the stdlib. Patch applies to 3.x as well.) -- components: +Library (Lib) -Extension Modules keywords: +patch nosy: +lehmannro Added file: http://bugs.python.org/file14909/issue5754.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue5754 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue6932] Open shelves fail when Python exits
New submission from Robert Lehmann lehman...@gmail.com:
I'm reopening issue5483 by Zhigang Wang (zhigang) as a separate bug.
Shelves that are still open when Python terminates will try to sync. If
writeback=True, this pickles cached items.
In this example, serialization of Test() re-imports __main__, which is
already gc'd, and raises:
Exception cPickle.PicklingError: Can't pickle class '__main__.Test':
it's not the same object as __main__.Test in bound method
Shelf.__del__ of {'a': __main__.Test object at 0x...}
The error is ignored (due to Python already tearing down) but all cached
modifications are lost.
The promise [t]he __del__() method of the Shelf class calls the close()
method, so the programmer generally need not do this explicitly is not
true with writeback enabled.
I'm unsure if this error can be fixed (probably with atexit/weakref, but
that's more trouble than gain). I attached a patch to the docs simply
warning the user of this issue (+ documenting Shelf.close, + removing
above quote).

[issue5483] [PATCH]Add FastDbfilenameShelf: shelf nerver sync cache even when writeback=True
Robert Lehmann lehman...@gmail.com added the comment: If I understand you correctly, your proposal is the following: use Shelf.cache to cache *all* objects instead of only keeping live references. Your patch retains the cache forever instead of purging it on sync. (All these changes only apply with writeback=True, which you enabled by default; nothing changes with writeback=False.) This speeds up *repeated* reads/writes as they are kept in-memory instead of querying the-- probably slow --database every time. I do not think this is a feasible solution for two reasons: (1) writeback was never intended to do such thing. It was introduced as a solution to make shelve less surprising. If you remove its sync-on-close characteristics, shelve is as surprising as before. See issue553171. (2) If you intend to implement caching on *any* database I'd suggest not using shelve for that matter. Using it for serialization is all okay but I'd rather add an additional layer of indirection to implement caching strategies if you want to do that The Right Way. (Shelf.cache is really only a map of objects that were touched during runtime.) I'm -1 on this patch but generally +1 on a generic caching wrapper. The error you describe later on appears because Python is already tearing down when gc'ing the Shelf (calling __del__ - close - sync). With writeback=True this currently tries to pickle the cache again which emits the error you observed. This should be handled in a separate issue. -- nosy: +lehmannro ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue5483 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue6105] json.dumps doesn't respect OrderedDict's iteration order
Robert Lehmann lehman...@gmail.com added the comment:
This only seems to be the case with the C implementation of json (_json).
json.encoder.c_make_encoder = None
json.dumps(OrderedDict(items))
'{one: 1, two: 2, three: 3, four: 4, five: 5}'
I think the culprit is encoder_listencode_dict (Modules/_json.c:2049).
It uses PyDict_Next to fetch all items from the dictionary and thereby
loses order. A special code branch for dict subclasses
(!PyDict_CheckExact) which uses PyIter* instead should solve the
problem. (PyDict_Next should not honor order no matter what IMO.)
If nobody beats me to it I can try to come up with a patch.

[issue5034] itertools.fixlen
Robert Lehmann lehman...@gmail.com added the comment: When I started writing this patch this was actually what I intended. But having ``fixlen(range(3), 2)`` return 0 1 2 struck me as odd. Renaming the function to `pad` would help there indeed. It depends on which use case is more common: either fixing an iterator to a certain length (slicing/padding applied as required) or obtaining an iterator of *at least* some number of elements (padded as required)? The thread on python-ideas suggests the latter while the example Python code brought up there implements the former. OTOH the latter cannot be composed *that easily* of other itertools but the former is more useful for unpacking. On a related note: what should happen if `length` is negative? `itertools.repeat` just defaults to 0 in such cases but I am unsure how applicable that is in this case. ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue5034 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

This is missing when you entered the code, that's why Python is throwing an exception there. -- nosy: +lehmannro __ Tracker [EMAIL PROTECTED] http://bugs.python.org/issue2201 __ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue2120] broken links in advocacy HOWTO
Robert Lehmann added the comment: Right, the second link requires a tilde -- I just tried the first one (which works without). You should change all lines to be 80 characters wide maximum, though (can quickly be done by any commiter, not worth a new patch IMO). The dash thing looks okay, --- is used a couple of times throughout the docs. __ Tracker [EMAIL PROTECTED] http://bugs.python.org/issue2120 __ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue1758] Wrong link in documentation
Robert Lehmann added the comment: This problem has been removed in the current version of the documentation (http://docs.python.org/dev/install/index.html) -- old docs aren't updated. It has an own section now (http://docs.python.org/dev/bugs.html). Issue can be closed. -- nosy: +lehmannro __ Tracker [EMAIL PROTECTED] http://bugs.python.org/issue1758 __ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
