* #1920: when considering a block starting by "while 0", the compiler ↵Amaury Forgeot d'Arc2008-01-241-1/+4
| | | | | | | | | | | | | | | | | optimized the whole construct away, even when an 'else' clause is present:: while 0: print("no") else: print("yes") did not generate any code at all. Now the compiler emits the 'else' block, like it already does for 'if' statements. Will backport.

| | | | The "can't load dll" message box on Windows is suppressed while an extension is loaded by calling SetErrorMode in dynload_win.c. The error is still reported properly.

* Provide a sanity check during PyThreadState_DeleteCurrent() andGregory P. Smith2008-01-211-0/+10
| | | | | | | | | | | | | | PyThreadState_Delete() to avoid an infinite loop when the tstate list is messed up and has somehow becomes circular and does not contain the current thread. I don't know how this happens but it does, *very* rarely. On more than one hardware platform. I have not been able to reproduce it manually. Attaching to a process where its happening: it has always been in an infinite loop over a single element tstate list that is not the tstate we're looking to delete. It has been in t_bootstrap()'s call to PyThreadState_DeleteCurrent() as a pthread is exiting.

* Continue rolling back pep-3141 changes that changed behavior from 2.5. ThisJeffrey Yasskin2008-01-051-17/+25
| | | | | | | | | | | | round included: * Revert round to its 2.6 behavior (half away from 0). * Because round, floor, and ceil always return float again, it's no longer necessary to have them delegate to __xxx___, so I've ripped that out of their implementations and the Real ABC. This also helps in implementing types that work in both 2.6 and 3.0: you return int from the __xxx__ methods, and let it get enabled by the version upgrade. * Make pow(-1, .5) raise a ValueError again.

* Partial port of r59682 from py3k.Amaury Forgeot d'Arc2008-01-041-1/+2
| | | | | | | | | | | On Windows, when import fails to load a dll module, the message says "error code 193" instead of a more informative text. It turns out that FormatMessage needs additional parameters for some error codes. For example: 193 means "%1 is not a valid Win32 application". Since it is impossible to know which parameter to pass, we use FORMAT_MESSAGE_IGNORE_INSERTS to get the raw message, which is still better than the number.

The only significant difference is that round(x) returns a float to preserve backward-compatibility. See http://bugs.python.org/issue1689.

* Give meaning to the oparg for BUILD_MAP: estimated size of the dictionary.Raymond Hettinger2007-12-182-5/+3
| | | | | | | | | | | Allows dictionaries to be pre-sized (upto 255 elements) saving time lost to re-sizes with their attendant mallocs and re-insertions. Has zero effect on small dictionaries (5 elements or fewer), a slight benefit for dicts upto 22 elements (because they had to resize once anyway), and more benefit for dicts upto 255 elements (saving multiple resizes during the build-up and reducing the number of collisions on the first insertions). Beyond 255 elements, there is no addional benefit.
* Speed-up dictionary constructor by about 10%.Raymond Hettinger2007-12-183-5/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | New opcode, STORE_MAP saves the compiler from awkward stack manipulations and specializes for dicts using PyDict_SetItem instead of PyObject_SetItem.
