* Issue #8914: fix various warnings from the Clang static analyzer v254.Brett Cannon2011-02-221-2/+2

* Remove filename variable from ceval.cVictor Stinner2011-02-211-16/+0
| | | | | | | Issue #11168: Remove filename debug variable from PyEval_EvalFrameEx(). It encoded the Unicode filename to UTF-8, but the encoding fails on undecodable filename (on surrogate characters) which raises an unexpected UnicodeEncodeError on recursion limit.
* Issue #10655: Fix the build on PowerPC on Linux with GCC when building withDavid Malcolm2011-01-061-4/+5
| | | | | | timestamp profiling (--with-tsc): the preprocessor test for the PowerPC support now looks for "__powerpc__" as well as "__ppc__": the latter seems to only be present on OS X; the former is the correct one for Linux with GCC.

* #4617: Previously it was illegal to delete a name from the localAmaury Forgeot d'Arc2010-09-101-16/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | namespace if it occurs as a free variable in a nested block. This limitation of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF). This sample was valid in 2.6, but fails to compile in 3.x without this change:: >>> def f(): ... def print_error(): ... print(e) ... try: ... something ... except Exception as e: ... print_error() ... # implicit "del e" here This sample has always been invalid in Python, and now works:: >>> def outer(x): ... def inner(): ... return x ... inner() ... del x There is no need to bump the PYC magic number: the new opcode is used for code that did not compile before.

* Make (most of) Python's tests pass under Thread Sanitizer.Jeffrey Yasskin2010-05-031-19/+44
| | | | | | | | | | | | | | | | | | http://code.google.com/p/data-race-test/wiki/ThreadSanitizer is a dynamic data race detector that runs on top of valgrind. With this patch, the binaries at http://code.google.com/p/data-race-test/wiki/ThreadSanitizer#Binaries pass many but not all of the Python tests. All of regrtest still passes outside of tsan. I've implemented part of the C1x atomic types so that we can explicitly mark variables that are used across threads, and get defined behavior as compilers advance. I've added tsan's client header and implementation to the codebase in dynamic_annotations.{h,c} (docs at http://code.google.com/p/data-race-test/wiki/DynamicAnnotations). Unfortunately, I haven't been able to get helgrind and drd to give sensible error messages, even when I use their client annotations, so I'm not supporting them.

This patch adds a PyCode_NewEmpty wrapper which lets the user specify just the filename, function name, and first line number, instead of also requiring lots of code internals. ........ r72488 | jeffrey.yasskin | 2009-05-08 18:23:21 -0400 (Fri, 08 May 2009) | 13 lines Issue 5954, PyFrame_GetLineNumber: Most uses of PyCode_Addr2Line (http://www.google.com/codesearch?q=PyCode_Addr2Line) are just trying to get the line number of a specified frame, but there's no way to do that directly. Forcing people to go through the code object makes them know more about the guts of the interpreter than they should need. The remaining uses of PyCode_Addr2Line seem to be getting the line from a traceback (for example, http://www.google.com/codesearch/p?hl=en#u_9_nDrchrw/pygame-1.7.1release/src/base.c&q=PyCode_Addr2Line), which is replaced by the tb_lineno field. So we may be able to deprecate PyCode_Addr2Line entirely for external use. ........ r72879 | jeffrey.yasskin | 2009-05-23 19:23:01 -0400 (Sat, 23 May 2009) | 14 lines Issue #6042: lnotab-based tracing is very complicated and isn't documented very well. There were at least 3 comment blocks purporting to document co_lnotab, and none did a very good job. This patch unifies them into Objects/lnotab_notes.txt which tries to completely capture the current state of affairs. I also discovered that we've attached 2 layers of patches to the basic tracing scheme. The first layer avoids jumping to instructions that don't start a line, to avoid problems in if statements and while loops. The second layer discovered that jumps backward do need to trace at instructions that don't start a line, so it added extra lnotab entries for 'while' and 'for' loops, and added a special case for backward jumps within the same line. I replaced these patches by just treating forward and backward jumps differently. ........

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch by Antoine Pitrou optimizes the bytecode for conditional branches by merging the following "POP_TOP" instruction into the conditional jump. For example, the list comprehension "[x for x in l if not x]" produced the following bytecode: 1 0 BUILD_LIST 0 3 LOAD_FAST 0 (.0) >> 6 FOR_ITER 23 (to 32) 9 STORE_FAST 1 (x) 12 LOAD_FAST 1 (x) 15 JUMP_IF_TRUE 10 (to 28) 18 POP_TOP 19 LOAD_FAST 1 (x) 22 LIST_APPEND 2 25 JUMP_ABSOLUTE 6 >> 28 POP_TOP 29 JUMP_ABSOLUTE 6 >> 32 RETURN_VALUE but after the patch it produces the following bytecode: 1 0 BUILD_LIST 0 3 LOAD_FAST 0 (.0) >> 6 FOR_ITER 18 (to 27) 9 STORE_FAST 1 (x) 12 LOAD_FAST 1 (x) 15 POP_JUMP_IF_TRUE 6 18 LOAD_FAST 1 (x) 21 LIST_APPEND 2 24 JUMP_ABSOLUTE 6 >> 27 RETURN_VALUE Notice that not only the code is shorter, but the conditional jump (POP_JUMP_IF_TRUE) jumps right to the start of the loop instead of going through the JUMP_ABSOLUTE at the end. "continue" statements are helped similarly. Furthermore, the old jump opcodes (JUMP_IF_FALSE, JUMP_IF_TRUE) have been replaced by two new opcodes: - JUMP_IF_TRUE_OR_POP, which jumps if true and pops otherwise - JUMP_IF_FALSE_OR_POP, which jumps if false and pops otherwise
