Guido van Rossum	c474deaaf6	Expand one level of symbolic link in sys.argv[0] before inserting its dirname in sys.path. This means that you can create a symbolic link foo in /usr/local/bin pointing to /usr/yourname/src/foo/foo.py, and then invoking foo will insert /usr/yourname/src/foo in sys.path, not /usr/local/bin. This makes it easier to have multifile programs (before, the program would have to do an os.readlink(sys.argv[0]) itself and insert the resulting directory in sys.path -- Grail does this). Note that the expansion is only used for sys.path; sys.argv[0] is still the original, unadorned filename (/usr/local/bin/foo in the example).	29 years ago
Guido van Rossum	03a7466b8f	OK, ready to make 'assert' a keyword (instead of '__assert__').	29 years ago
Guido van Rossum	7844e38a98	Keep Microsoft VC happy.	29 years ago
Guido van Rossum	6bf62dad9e	Keep gcc -Wall and Microsoft VC happy.	29 years ago
Guido van Rossum	1d2e240954	(Jack:) On the Mac, don't automatically enable dynamic loading.	29 years ago
Guido van Rossum	62bf108392	(Jack:) Don't define TRUE and FALSE if already defined.	29 years ago
Guido van Rossum	6976a52099	(Jack:) On the Mac, use standard strerror() if using MSL C-library.	29 years ago
Guido van Rossum	644a12b00c	Tweaks to keep the Microsoft compiler quier.	29 years ago
Guido van Rossum	5f5e817e00	Support for alternative string quotes (a"xx", b"xx", c"xx", ...). In interactive mode, do generate code for single-string statements.	29 years ago
Guido van Rossum	2a7f58de1c	Allow passing a .pyo file. Print correct name in fatal error from PyErr_Print.	29 years ago
Guido van Rossum	228d7f3f67	Added assert statement.	29 years ago
Guido van Rossum	8ecd1ad785	Added assert grammar.	29 years ago
Guido van Rossum	c6472e9ee1	1. Add string conversions to int(), long(), float(). (Not to complex()!) 2. Fix two bugs in complex(): - Memory leak when using complex(classinstance) -- r was never DECREF'ed. - Conversion of the second argument, if not complex, was done using the type vector of the 1st.	29 years ago
Guido van Rossum	45b83915f8	New form of PyFPE_END_PROTECT macro.	29 years ago
Guido van Rossum	6af0c00ab6	Fix dumb bug calling parsestrplus with wrong node as argument. Add prototypes for parsestr() and parsestrplus() (unrelated, but seemed to make sense.)	29 years ago
Guido van Rossum	1c6a459921	Define __debug__ as 0 if -O is given, 1 otherwise. Also test for errors in initializing the dictionary.	29 years ago
Guido van Rossum	7c53111d5b	Added support for ``if __debug__:'' -- if -O is given, this form is recognized by the code generator and code generation for the test and the subsequent suite is suppressed. One must write exactly ``if __debug__:'' or ``elif __debug__:'' -- no parentheses or operators must be present, or the optimization is not carried through. Whitespace doesn't matter. Other uses of __debug__ will find __debug__ defined as 0 or 1 in the __builtin__ module.	29 years ago
Guido van Rossum	0824f63cfc	When -O is given, use ".pyo" instead of ".pyc".	29 years ago
Guido van Rossum	c43b685054	Clarify error message for unexpected keyword parameter.	29 years ago
Guido van Rossum	82598051e6	Greatly renamed. Not a very thorough job -- I'm going to restructure it anyway.	29 years ago
Guido van Rossum	8e793d925c	Add global Py_OptimizeFlag. SET_LINENO is omitted again unless this is nonzero.	29 years ago
Guido van Rossum	0ae748d3c4	Changes for Lee Busby's SIGFPE patch set. New file pyfpe.c and exception FloatingPointError. Surround some f.p. operations with PyFPE macro brackets.	29 years ago
Guido van Rossum	0f4bbd2f34	Keep gcc -Wall happy.	29 years ago
Guido van Rossum	2dc466169e	Oops, remove an unused variable from PyErr_Format().	29 years ago
Guido van Rossum	7433b12a5c	Added new global flag variable Py_InteractiveFlag and new function Py_FdIsInteractive(). The flag is supposed to be set by the -i command line option. The function is supposed to be called instead of isatty(). This is used for Lee Busby's wish #1, to have an option that pretends stdin is interactive even when it really isn't.	29 years ago
Guido van Rossum	1548bacb14	Added convenience function PyErr_Format(exception, formatstring, ...) -> NULL.	29 years ago
Guido van Rossum	0d85be19e2	Don't kill all local variables on function exit. This will be done by the frameobject dealloc when it is time for the locals to go. When there's still a traceback object referencing this stack frame, we don't want the local variables to disappear yet. (Hmm... Shouldn't they be copied to the f_locals dictionary?)	29 years ago
Guido van Rossum	e8811f85ed	Added intern() function.	29 years ago
Guido van Rossum	deb0c5e66c	Two small changes: - Use co->... instead of f->f_code->...; save an extra lookup of what we already have in a local variable). - Remove test for nlocals > 0 before setting fastlocals to f->f_localsplus; 0 is a rare case and the assignment is safe even then.	29 years ago
Guido van Rossum	d0eb429b88	Plug a leak with calling something other than a function or method is called with keyword arguments -- the keyword and value were leaked. This affected for instance with a __call__() method. Bug reported and fix supplied by Jim Fulton.	29 years ago
Guido van Rossum	950361c6ca	Patches for (two forms of) optional dynamic execution profiling -- i.e., counting opcode frequencies, or (with DXPAIRS defined) opcode pair frequencies. Define DYNAMIC_EXECUTION_PROFILE on the command line (for this file and for sysmodule.c) to enable.	29 years ago
Guido van Rossum	8c5df06ec7	Change the control flow for error handling in the function prelude to jump to the "Kill locals" section at the end. Add #ifdef macintosh bandaid to make sure we call sigcheck() on the Mac.	29 years ago
Guido van Rossum	43f1b8d6e4	Added optional interface for dynamic execution profile (to be gathered in ceval.c).	29 years ago
Guido van Rossum	b3f515af64	Get the line number from PyCode_Addr2Line instead of believing tb_lineno. Store it in tb_lineno for the user.	29 years ago
Guido van Rossum	99d182550b	New magin number (because of linenumber table).	29 years ago
Guido van Rossum	d031c89891	Marshal the line number table of code objects.	29 years ago
Guido van Rossum	da4eb5c3b5	Instead of emitting SET_LINENO instructions, generate a line number table which is incorporated in the code object. This way, the runtime overhead to keep track of line numbers is only incurred when an exception has to be reported.	29 years ago
Guido van Rossum	a4240132ec	Kill all local variables on function return. This closes a gigantic leak of memory and file descriptors (thanks for Roj for reporting that!). Alas, the speed goes down by 5%. :-(	29 years ago
Guido van Rossum	70d44787a3	Only call sigcheck() at the ticker code if we don't have true signals. This is safe now that both intrcheck() and signalmodule.c schedule a sigcheck() call via Py_AddPendingCall(). This gives another 7% speedup (never run such a test twice ;-).	29 years ago
Guido van Rossum	1aa14838d2	Cleanup: - fix bug in Py_MakePendingCalls() with threading - fix return type of do_raise - remove build_slice (same as PySlice_New) - remove code inside #if 0 - remove code inside #ifdef CHECK_STACK - remove code inside #ifdef SUPPORT_OBSOLETE_ACCESS - comment about newimp.py should refer to ni.py	29 years ago
Guido van Rossum	554fa49500	get build info from elsewhere	29 years ago
Guido van Rossum	768360243a	Changes for frame object speedup: - get fastlocals differently - call newframeobject() with fewer arguments - toss getowner(), which was unused anyway	29 years ago
Guido van Rossum	7eb883a18e	Remove unused variable.	29 years ago
Guido van Rossum	8d75161671	Intern the string "__complex__".	29 years ago
Guido van Rossum	7b89b6a660	Intern all names and varnames in newcodeobject(), plus those string literals that look like identifiers. Also intern all strings used as names during the compilation.	29 years ago
Guido van Rossum	3dfd53b4c8	Add "if (x != NULL) continue;" (or similar for err==0) before the break to most cases, as suggested by Tim Peters. This gives another 8-10% speedup.	29 years ago
Guido van Rossum	98a9b312e8	Marshal the new stacksize item in code objects.	29 years ago
Guido van Rossum	7af8130857	Working semaphore implementation by Sjoerd.	29 years ago
Guido van Rossum	dd5db43905	New MAGIC number (code objects have one more item when marshalled).	29 years ago
Guido van Rossum	62f7d15d0b	Use the stack size from the code object and the CO_MAXBLOCKS constant from compile.h. Remove all eval stack overflow checks.	29 years ago
