* It's unclear whether PyMarshal_XXX() are part of the public or private API.Tim Peters2001-01-281-33/+49
| | | | | | | | | | 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.

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.

* SF bug 119622: compile errors due to redundant atof decls. I don't understandTim Peters2000-11-141-2/+0
| | | | | | the bug report (for details, look at it), but agree there's no need for Python to declare atof itself: we #include stdlib.h, and ANSI C sez atof is declared there already.
* Obscure marshal fixes:Tim Peters2000-09-191-4/+4
| | | | | | | | When reading a short, sign-extend on platforms where shorts are bigger than 16 bits. When reading a long, repair the unportable sign extension that was being done for 64-bit machines (it assumed that signed right shift sign-extends).
* REMOVED all CWI, CNRI and BeOpen copyright markings.Guido van Rossum2000-09-011-9/+0
| | | | This should match the situation in the 1.6b1 tree.
* Included assert.h in Python.h -- it's absurd that this basic tool ofTim Peters2000-07-231-1/+1
| | | | | | | | good C practice hasn't been available to everything all along. Added Py_SAFE_DOWNCAST(VALUE, WIDE, NARROW) macro to pyport.h; this just casts VALUE from type WIDE to type NARROW, but assert-fails if Py_DEBUG is defined and info is lost due to casting. Replaced a line in Fredrik's fix to marshal.c to use the new macro.

* Urmpf. Quality control on this patch lapsed a bit. :-(Guido van Rossum2000-06-281-2/+6
| | | | | | | | | | | The depth field was never decremented inside w_object(), and it was never initialized in PyMarshal_WriteObjectToFile(). This caused imports from .pyc files to fil mysteriously when the .pyc file was written by the broken code -- w_object() would bail out early, but PyMarshal_WriteObjectToFile() doesn't check the error or return an error code, and apparently the marshalling code doesn't call PyErr_Check() either. (That's a separate patch if I feel like it.)
* Michael Hudson <mwh21@cam.ac.uk>:Fred Drake2000-06-281-3/+22
| | | | | | | | | | | | | As I really do not have anything better to do at the moment, I have written a patch to Python/marshal.c that prevents Python dumping core when trying to marshal stack bustingly deep (or recursive) data structure. It just throws an exception; even slightly clever handling of recursive data is what pickle is for... [Fred Drake:] Moved magic constant 5000 to a #define. This closes SourceForge patch #100645.
* Vladimir Marangozov's long-awaited malloc restructuring.Guido van Rossum2000-05-031-4/+4
| | | | | | | | | | For more comments, read the patches@python.org archives. For documentation read the comments in mymalloc.h and objimpl.h. (This is not exactly what Vladimir posted to the patches list; I've made a few changes, and Vladimir sent me a fix in private email for a problem that only occurs in debug mode. I'm also holding back on his change to main.c, which seems unnecessary to me.)

* When unmarshalling, add test for negative lengths on strings, tuplesGuido van Rossum1998-06-081-2/+14
| | | | | | and lists; if the size is negative, raise an exception. Also raise an exception when an undefined type is found -- all this to increase the chance that garbage input causes an exception instead of a core dump.

* Make new gcc -Wall happyGuido van Rossum1998-04-101-4/+7

* Plugged a leak. (The same as the one plugged in compile.c -- forgotGuido van Rossum1997-07-261-0/+1

| | | | Tested with AMK's help.
* Tentative changes to make this work better on 64-bit machines.Guido van Rossum1996-12-051-3/+66
| | | | | A plain int that doesn't fit in 32 bits will be marshalled using a new type. 32 bits machines can't handle this and will issue a warning.
* New permission notice, includes CNRI.Guido van Rossum1996-10-251-13/+20
|
* Ellipses -> Ellipsis rename (the dictionary really says that it shouldGuido van Rossum1996-10-111-6/+6
| | | | | | | | be Ellipsis!). Bumped the API version because a linker-visible symbol is affected. Old C code will still compile -- there's a b/w compat macro. Similarly, old Python code will still run, builtin exports both Ellipses and Ellipsis.
* Added *PyMarshal_WriteObjectToString() (moved the relevant code thereGuido van Rossum1996-08-191-18/+25

The second interrupt prints a message explaining this to the user.
