* It's unclear whether PyMarshal_XXX() are part of the public or private API.Tim Peters2001-01-283-35/+51
| | | | | | | | | | They're named as if public, so I did a Bad Thing by changing PyMarshal_ReadObjectFromFile() to suck up the remainder of the file in one gulp: anyone who counted on that leaving the file pointer merely at the end of the next object would be screwed. So restored PyMarshal_ReadObjectFromFile() to its earlier state, renamed the new greedy code to PyMarshal_ReadLastObjectFromFile(), and changed Python internals to call the latter instead.
* SF bug http://sourceforge.net/bugs/?func=detailbug&bug_id=130242&group_id=5470Tim Peters2001-01-271-0/+1
| | | | | | | | SF patch http://sourceforge.net/patch/?func=detailpatch&patch_id=103453&group_id=5470 PyMember_Set of T_CHAR always raises exception. Unfortunately, this is a use of a C API function that Python itself never makes, so there's no .py test I can check in to verify this stays fixed. But the fault in the code is obvious, and Dave Cole's patch just as obviously fixes it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The majority of the changes are in the compiler. The mainloop changes primarily to implement the new opcodes and to pass a function's closure to eval_code2(). Frames and functions got new slots to hold the closure. Include/compile.h Add co_freevars and co_cellvars slots to code objects. Update PyCode_New() to take freevars and cellvars as arguments Include/funcobject.h Add func_closure slot to function objects. Add GetClosure()/SetClosure() functions (and corresponding macros) for getting at the closure. Include/frameobject.h PyFrame_New() now takes a closure. Include/opcode.h Add four new opcodes: MAKE_CLOSURE, LOAD_CLOSURE, LOAD_DEREF, STORE_DEREF. Remove comment about old requirement for opcodes to fit in 7 bits. compile.c Implement changes to code objects for co_freevars and co_cellvars. Modify symbol table to use st_cur_name (string object for the name of the current scope) and st_cur_children (list of nested blocks). Also define st_nested, which might more properly be called st_cur_nested. Add several DEF_XXX flags to track def-use information for free variables. New or modified functions of note: com_make_closure(struct compiling *, PyCodeObject *) Emit LOAD_CLOSURE opcodes as needed to pass cells for free variables into nested scope. com_addop_varname(struct compiling *, int, char *) Emits opcodes for LOAD_DEREF and STORE_DEREF. get_ref_type(struct compiling *, char *name) Return NAME_CLOSURE if ref type is FREE or CELL symtable_load_symbols(struct compiling *) Decides what variables are cell or free based on def-use info. Can now raise SyntaxError if nested scopes are mixed with exec or from blah import *. make_scope_info(PyObject *, PyObject *, int, int) Helper functions for symtable scope stack. symtable_update_free_vars(struct symtable *) After a code block has been analyzed, it must check each of its children for free variables that are not defined in the block. If a variable is free in a child and not defined in the parent, then it is defined by block the enclosing the current one or it is a global. This does the right logic. symtable_add_use() is now a macro for symtable_add_def() symtable_assign(struct symtable *, node *) Use goto instead of for (;;) Fixed bug in symtable where name of keyword argument in function call was treated as assignment in the scope of the call site. Ex: def f(): g(a=2) # a was considered a local of f ceval.c eval_code2() now take one more argument, a closure. Implement LOAD_CLOSURE, LOAD_DEREF, STORE_DEREF, MAKE_CLOSURE> Also: When name error occurs for global variable, report that the name was global in the error mesage. Objects/frameobject.c Initialize f_closure to be a tuple containing space for cellvars and freevars. f_closure is NULL if neither are present. Objects/funcobject.c Add support for func_closure. Python/import.c Change the magic number. Python/marshal.c Track changes to code objects.

| | | | | | | | | | | | | module__doc__: Document the Warning subclass heirarchy. make_class(): Added a "goto finally" so that if populate_methods() fails, the return status will be -1 (failure) instead of 0 (success). fini_exceptions(): When decref'ing the static pointers to the exception classes, clear out their dictionaries too. This breaks a cycle from class->dict->method->class and allows the classes with unbound methods to be reclaimed. This plugs a large memory leak in a common Py_Initialize()/dosomething/Py_Finalize() loop.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | 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.

* 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 :-).
