* Small changes to map() and filter():Guido van Rossum1998-07-101-5/+8
| | | | | | | (1) If a sequence S is shorter than len(S) indicated, don't fail -- just use the shorter size. (I.e, len(S) is just a hint.) (2) Implement the special case map(None, S) as list(S) -- it's faster.

* Sigh. The hack to enable special treatment for errno on SGI machinesGuido van Rossum1998-07-071-0/+4
| | | | | | | | | must be enabled here, otherwise the errno we set on overflows is not the errno that's being read by compile.c. Wonder how many other files that do their own "#include config.h" need this too :-( (Because of the structure of autoconf, it's not so simple to get this into config.h...)

* Moved cmp_member() to abstract.c, as PySequence_Contains() [withGuido van Rossum1998-05-221-53/+2
| | | | | | | | swapped arguments]. Also make sure that no use of a function pointer gotten from a tp_as_sequence or tp_as_mapping structure is made without checking it for NULL first.
* A bunch of functions are now properly implemented in abstract.c, andGuido van Rossum1998-05-221-356/+40
| | | | | | | | | | | the code here becomes much simpler. In particular: abs(), divmod(), pow(), int(), long(), float(), len(), tuple(), list(). Also make sure that no use of a function pointer gotten from a tp_as_sequence or tp_as_mapping structure is made without checking it for NULL first. A few other cosmetic things, such as properly reindenting slice().
* Trivial little change: when setting a member to an object, hold theGuido van Rossum1998-05-201-1/+3
| | | | | | | old value in a temporary and XDECREF it only after then new value has been set. This prevents the (unlikely) case where the destructor of the member uses the containing object -- it would find it in an undefined state.
* Fix a curious bug: statements like "import sys.time" would succeed,Guido van Rossum1998-05-191-3/+10
| | | | | | because the path through the code would notice that sys.__path__ did not exist and it would fall back to the default path (builtins + sys.path) instead of failing). No longer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Date: Thu, 14 Sep 1995 12:18:20 -0400 From: Alan Morse <alan@dvcorp.com> To: python-list@cwi.nl Subject: getargs bug in 1.2 and 1.3 BETA We have found a bug in the part of the getargs code that we added and submitted, and which was incorporated into 1.1. The parsing of "O?" format specifiers is not handled correctly; there is no "else" for the "if" and therefore it can never fail. What's worse, the advancing of the varargs pointer is not handled properly, so from then on it is out of sync, wreaking all sorts of havoc. (If it had failed properly, then the out-of-sync varargs would not have been an issue.) Below is the context diff for the change. Note that I have made a few stylistic changes beyond adding the else case, namely: 1) Making the "O" case follow the convention established by the other format specifiers of getting all their vararg arguments before performing the test, rather than getting some before and some after the test passes. 2) Making the logic of the tests parallel, so the "if" part indicates that the format is accepted and the "else" part indicates that the format has failed. They were inconsistent with each other and with the the other format specifiers. -Alan Morse (amorse@dvcorp.com)

* New APIs to write to sys.stdout or sys.stderr using a printf-like interface.Guido van Rossum1998-05-121-0/+90
| | | | | | | | | | | | | | | | | | | | | | | | Adapted from code submitted by Just van Rossum. PySys_WriteStdout(format, ...) PySys_WriteStderr(format, ...) The first function writes to sys.stdout; the second to sys.stderr. When there is a problem, they write to the real (C level) stdout or stderr; no exceptions are raised (but a pending exception may be cleared when a new exception is caught). Both take a printf-style format string as their first argument followed by a variable length argument list determined by the format string. *** WARNING *** The format should limit the total size of the formatted output string to 1000 bytes. In particular, this means that no unrestricted "%s" formats should occur; these should be limited using "%.<N>s where <N> is a decimal number calculated so that <N> plus the maximum size of other formatted text does not exceed 1000 bytes. Also watch out for "%f", which can print hundreds of digits for very large numbers.

* Add a single Python-wide (!) lock on import. Only one thread at aGuido van Rossum1998-03-031-8/+71
| | | | | | | | | | | | | | | | | | | | time can be in PyImport_ImportModuleEx(). Recursive calls from the same thread are okay. Potential problems: - The lock should really be part of the interpreter state rather than global, but that would require modifying more files, and I first want to figure out whether this works at all. - One could argue that the lock should be per module -- however that would be complicated to implement. We would have to have a linked list of locks per module name, *or* invent a new object type to represent a lock, so we can store the locks in the module or in a separate dictionary. Both seem unwarranted. The one situation where this can cause problems is when loading a module takes a long time, e.g. when the module's initialization code interacts with the user -- during that time, no other threads can run. I say, "too bad."
