* No need to emit co_lnotab item when both offsets are zeros.Amaury Forgeot d'Arc2008-02-041-0/+3
| | | | | | r60579 broke a test test_compile, which seems to test an "implementation detail" IMO. Also test that this correction does not impact the debugger.

| | | | | | | | | | | | | | iteration of a while statement. The mapping between bytecode offsets and source lines (lnotab) did not contain an entry for the beginning of the loop. Now it does, and the lnotab can be a bit larger: in particular, several statements on the same line generate several entries. However, this does not bother the settrace function, which will trigger only one 'line' event. The lnotab seems to be exactly the same as with python2.4.

| | | | | | | | | | | | | | | | | 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. Backport of r60265.

* Backport 52504:Neal Norwitz2006-10-281-1/+4
| | | | | | Fix bug #1565514, SystemError not raised on too many nested blocks. It seems like this should be a different error than SystemError, but I don't have any great ideas and SystemError was raised in 2.4 and earlier.
* Fix #1569998: no break inside try statement (outside loop) allowed.Georg Brandl2006-10-081-1/+13

* Even though _Py_Mangle() isn't truly public anyone can call it andNeal Norwitz2006-08-121-2/+2
| | | | | | | | | | there was no verification that privateobj was a PyString. If it wasn't a string, this could have allowed a NULL pointer to creep in below and crash. I wonder if this should be PyString_CheckExact? Must identifiers be strings or can they be subclasses? Klocwork #275
* Bug #1333982: string/number constants were inappropriately storedNeal Norwitz2006-08-041-2/+4
| | | | | in the byte code and co_consts even if they were not used, ie immediately popped off the stack.
* Bug #1191458: tracing over for loops now produces a line eventNeal Norwitz2006-08-041-7/+46
| | | | | | | | | | | | on each iteration. I'm not positive this is the best way to handle this. I'm also not sure that there aren't other cases where the lnotab is generated incorrectly. It would be great if people that use pdb or tracing could test heavily. Also: * Remove dead/duplicated code that wasn't used/necessary because we already handled the docstring prior to entering the loop. * add some debugging code into the compiler (#if 0'd out).
* Add some asserts and update commentsNeal Norwitz2006-07-301-0/+1

* If the for loop isn't entered, entryblock will be NULL. If passedNeal Norwitz2006-07-231-0/+2

* per Jeremy's email, remove the _WITH_CAST versions of macros. g++Anthony Baxter2006-04-121-46/+24
| | | | | still has errors from the casts of asdl_seq_GET to cmpop_ty, but otherwise it's C++ clean.
* more low-hanging fruit to make code compile under a C++ compiler. NotAnthony Baxter2006-04-111-54/+85
| | | | | entirely happy with the two new VISIT macros in compile.c, but I couldn't see a better approach.

* Generate line number table entries for except handlers.Jeremy Hylton2006-04-041-0/+2
| | | | Re-enable all the tests in test_trace.py except one. Still not sure that these tests test what they used to test, but they pass. One failing test seems to be caused by undocumented line number table behavior in Python 2.4.

* Um, I thought I'd already checked this in.Guido van Rossum2006-03-101-3/+1
| | | | | | | Anyway, this is the changes to the with-statement so that __exit__ must return a true value in order for a pending exception to be ignored. The PEP (343) is already updated.

* Generally inehrit codeflags that are in PyCF_MASK, instead of writing it outThomas Wouters2006-02-281-4/+4

* SF patch #1438387, PEP 328: relative and absolute imports.Thomas Wouters2006-02-281-0/+27
| | | | | | | | | | | | | | | | | | | | | | | - IMPORT_NAME takes an extra argument from the stack: the relativeness of the import. Only passed to __import__ when it's not -1. - __import__() takes an optional 5th argument for the same thing; it __defaults to -1 (old semantics: try relative, then absolute) - 'from . import name' imports name (be it module or regular attribute) from the current module's *package*. Likewise, 'from .module import name' will import name from a sibling to the current module. - Importing from outside a package is not allowed; 'from . import sys' in a toplevel module will not work, nor will 'from .. import sys' in a (single-level) package. - 'from __future__ import absolute_import' will turn on the new semantics for import and from-import: imports will be absolute, except for from-import with dots. Includes tests for regular imports and importhooks, parser changes and a NEWS item, but no compiler-package changes or documentation changes.
