* bpo-32176: Set CO_NOFREE in the code object constructor (GH-4675)Nick Coghlan2017-12-031-1/+9
| | | | | | | | Previously, CO_NOFREE was set in the compiler, which meant it could end up being set incorrectly when code objects were created directly. Setting it in the constructor based on freevars and cellvars ensures it is always accurate, regardless of how the code object is defined.

Changes: * assemble_lnotab(): if line number delta is less than -128 or greater than 127, emit multiple (offset_delta, lineno_delta) in co_lnotab * update functions decoding co_lnotab to use signed 8-bit integers - dis.findlinestarts() - PyCode_Addr2Line() - _PyCode_CheckLineNumber() - frame_setlineno() * update lnotab_notes.txt * increase importlib MAGIC_NUMBER to 3361 * document the change in What's New in Python 3.6 * cleanup also PyCode_Optimize() to use better variable names

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. ........
