* See discussion at SF bug 547537.Guido van Rossum2002-04-291-1/+1
| | | | | | | | | | | Unicode objects are currently taken as binary data by the write() method. This is not what Unicode users expect, nor what the StringIO.py code does. Until somebody adds a way to specify binary or text mode for cStringIO objects, change the format string to use "t#" instead of "s#", so that it will request the "text buffer" version. This will try the default encoding for Unicode objects. This is *not* a 2.2 bugfix (since it *is* a semantic change).
* Mostly in SequenceMatcher.{__chain_b, find_longest_match}:Tim Peters2002-04-293-34/+84
| | | | | | | | | | | | This now does a dynamic analysis of which elements are so frequently repeated as to constitute noise. The primary benefit is an enormous speedup in find_longest_match, as the innermost loop can have factors of 100s less potential matches to worry about, in cases where the sequences have many duplicate elements. In effect, this zooms in on sequences of non-ubiquitous elements now. While I like what I've seen of the effects so far, I still consider this experimental. Please give it a try!

* Moving pymalloc along.Tim Peters2002-04-282-112/+131
| | | | | | | | | | As threatened, PyMem_{Free, FREE} also invoke the object deallocator now when pymalloc is enabled (well, it does when pymalloc isn't enabled too, but in that case "the object deallocator" is plain free()). This is maximally backward-compatible, but it leaves a bitter aftertaste. Also massive reworking of comments.
* _PyObject_GC_New: Could call PyObject_INIT with a NULL 1st argument.Tim Peters2002-04-281-2/+6
| | | | | | _PyObject_GC_NewVar: Could call PyObject_INIT_VAR likewise. Bugfix candidate.
* Repair widespread misuse of _PyString_Resize. Since it's clear peopleTim Peters2002-04-2714-90/+54
| | | | | | | | | | | | | | | | | | | | | | don't understand how this function works, also beefed up the docs. The most common usage error is of this form (often spread out across gotos): if (_PyString_Resize(&s, n) < 0) { Py_DECREF(s); s = NULL; goto outtahere; } The error is that if _PyString_Resize runs out of memory, it automatically decrefs the input string object s (which also deallocates it, since its refcount must be 1 upon entry), and sets s to NULL. So if the "if" branch ever triggers, it's an error to call Py_DECREF(s): s is already NULL! A correct way to write the above is the simpler (and intended) if (_PyString_Resize(&s, n) < 0) goto outtahere; Bugfix candidate.
* SF patch 549375: Compromise PyUnicode_EncodeUTF8Tim Peters2002-04-271-108/+70
| | | | | | | | | | | | | | | | | | | | This implements ideas from Marc-Andre, Martin, Guido and me on Python-Dev. "Short" Unicode strings are encoded into a "big enough" stack buffer, then exactly as much string space as they turn out to need is allocated at the end. This should have speed benefits akin to Martin's "measure once, allocate once" strategy, but without needing a distinct measuring pass. "Long" Unicode strings allocate as much heap space as they could possibly need (4 x # Unicode chars), and do a realloc at the end to return the untouched excess. Since the overallocation is likely to be substantial, this shouldn't burden the platform realloc with unusably small excess blocks. Also simplified uses of the PyString_xyz functions. Also added a release- build check that 4*size doesn't overflow a C int. Sooner or later, that's going to happen.

* - New builtin function enumerate(x), from PEP 279. Example:Guido van Rossum2002-04-267-0/+281
| | | | | enumerate("abc") is an iterator returning (0,"a"), (1,"b"), (2,"c"). The argument can be an arbitrary iterable object.

* PyNumber_CoerceEx: this took a shortcut (not doing anything) when theGuido van Rossum2002-04-262-1/+8
| | | | | | | | | | | | | | | | | | | | | left and right type were of the same type and not classic instances. This shortcut is dangerous for proxy types, because it means that coerce(Proxy(1), Proxy(2.1)) leaves Proxy(1) unchanged rather than turning it into Proxy(1.0). In an ever-so-slight change of semantics, I now only take the shortcut when the left and right types are of the same type and don't have the CHECKTYPES feature. It so happens that classic instances have this flag, so the shortcut is still skipped in this case (i.e. nothing changes for classic instances). Proxies also have this flag set (otherwise implementing numeric operations on proxies would become nightmarish) and this means that the shortcut is also skipped there, as desired. It so happens that int, long and float also have this flag set; that means that e.g. coerce(1, 1) will now invoke int_coerce(). This is fine: int_coerce() can deal with this, and I'm not worried about the performance; int_coerce() is only invoked when the user explicitly calls coerce(), which should be rarer than rare.

* Make sure that tp_free frees the int the same way as tp_dealloc would.Guido van Rossum2002-04-261-0/+8
| | | | | | | | | This fixes the problem that Barry reported on python-dev: >>> 23000 .__class__ = bool crashes in the deallocator. This was because int inherited tp_free from object, which uses the default allocator. 2.2. Bugfix candidate.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | better auto-recognition of a Jython file vs. a CPython (or agnostic) file by looking at the #! line more closely, and inspecting the import statements in the first 20000 bytes (configurable). Specifically, (py-import-check-point-max): New variable, controlling how far into the buffer it will search for import statements. (py-jpython-packages): List of package names that are Jython-ish. (py-shell-alist): List of #! line programs and the modes associated with them. (jpython-mode-hook): Extra hook that runs when entering jpython-mode (what about Jython mode? <20k wink>). (py-choose-shell-by-shebang, py-choose-shell-by-import, py-choose-shell): New functions. (python-mode): Use py-choose-shell. (jpython-mode): New command. (py-execute-region): Don't use my previous hacky attempt at doing this, use the new py-choose-shell function. One other thing this file now does: it attempts to add the proper hooks to interpreter-mode-alist and auto-mode-alist if they aren't already there. Might help with Emacs users since that editor doesn't come with python-mode by default.
