| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | symbol table for each top-level compilation unit. The information in the symbol table allows the elimination of the later optimize() pass; the bytecode generation emits the correct opcodes. The current version passes the complete regression test, but may still contain some bugs. It's a fairly substantial revision. The current code adds an assert() and a test that may lead to a Py_FatalError(). I expect to remove these before 2.1 beta 1. The symbol table (struct symtable) is described in comments in the code. The changes affects the several com_XXX() functions that were used to emit LOAD_NAME and its ilk. The primary interface for this bytecode is now com_addop_varname() which takes a kind and a name, where kind is one of VAR_LOAD, VAR_STORE, or VAR_DELETE. There are many other smaller changes: - The name mangling code is no longer contained in ifdefs. There are two functions that expose the mangling logical: com_mangle() and symtable_mangle(). - The com_error() function can accept NULL for its first argument; this is useful with is_constant_false() is called during symbol table generation. - The loop index names used by list comprehensions have been changed from __1__ to [1], so that they can not be accessed by Python code. - in com_funcdef(), com_argdefs() is now called before the body of the function is compiled. This provides consistency with com_lambdef() and symtable_funcdef(). - Helpers do_pad(), dump(), and DUMP() are added to aid in debugging the compiler.

* Two changes to from...import:Guido van Rossum2001-01-121-30/+54
| | | | | | | | | | | 1) "from M import X" now works even if M is not a real module; it's basically a getattr() operation with AttributeError exceptions changed into ImportError. 2) "from M import *" now looks for M.__all__ to decide which names to import; if M.__all__ doesn't exist, it uses M.__dict__.keys() but filters out names starting with '_' as before. Whether or not __all__ exists, there's no restriction on the type of M.

Added regression tests to detect errors for this.

* Revised implementation of CALL_FUNCTION and friends.Jeremy Hylton2001-01-031-296/+429
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | More revision still needed. Much of the code that was in the mainloop was moved to a series of helper functions. PyEval_CallObjectWithKeywords was split into two parts. The first part now only does argument handling. The second part is now named call_object and delegates the call to a call_(function,method,etc.) helper. XXX The call_XXX helper functions should be replaced with tp_call functions for the respective types. The CALL_FUNCTION implementation contains three kinds of optimization: 1. fast_cfunction and fast_function are called when the arguments on the stack can be passed directly to eval_code2() without copying them into a tuple. 2. PyCFunction objects are dispatched immediately, because they are presumed to occur more often than anything else. 3. Bound methods are dispatched inline. The method object contains a pointer to the function object that will be called. The function is called from within the mainloop, which may allow optimization #1 to be used, too. The extened call implementation -- f(*args) and f(**kw) -- are implemented as a separate case in the mainloop. This allows the common case of normal function calls to execute without wasting time on checks for extended calls, although it does introduce a small amount of code duplication. Also, the unused final argument of eval_code2() was removed. This is probably the last trace of the access statement :-).

Fix Demo/pyserv/pyserv.c to include getopt.h itself, instead of relying on Python to provide it.
