* Unpickler.load_inst(), Unpickler.load_obj(), Unpickler.load_build():Barry Warsaw1998-01-261-7/+28
| | | | | | | | | | | | Fixed problems when unpickling in restricted execution environments. These methods try to assign to an instance's __class__ attribute, or access the instances __dict__, which are prohibited in REE. For the first two methods, I re-implemented the old behavior when assignment to value.__class__ fails. For the load_build() I also re-implemented the old behavior when inst.__dict__.update() fails but this means that unpickling in REE is semantically different than unpickling in unrestricted mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | The attached patch adds the following behavior to the handling of REDUCE codes: - A user-defined type may have a __reduce__ method that returns a string rather than a tuple, in which case the object is saved as a global object with a name given by the string returned by reduce. This was a feature added to cPickle a long time ago. - User-defined types can now support unpickling without executing a constructor. The second value returned from '__reduce__' can now be None, rather than an argument tuple. On unpickling, if the second value returned from '__reduce__' during pickling was None, then rather than calling the first value returned from '__reduce__', directly, the '__basicnew__' method of the first value returned from '__reduce__' is called without arguments. I also got rid of a few of Chris' extra ()s, which he used to make python ifs look like C ifs.
* Don't specify base 0 to string.atoi when unpickling integers in textGuido van Rossum1997-12-101-1/+1
| | | | | | mode. The pickler always uses base 10 so the default base should be fine. (The base gets us in trouble when there's no strop module, as the atoi() in string.py only supports base 10. This is for JPython.)
* When instantiating a class with no arguments and where the class doesGuido van Rossum1997-12-051-135/+40
| | | | | | | | | | | not define __getinitargs__, bypass the __init__ constructor completely. This uses the trick of instantiating an empty dummy class and then changing inst.__class__ to the real class. This is done in two places: once for the INST and once for the OBJ format code. Also replaced the much outdated long doc string with a short summary of the module; the information of that doc string is already incorporated in the library reference manual.
* Three independent changes:Guido van Rossum1997-09-121-5/+10
| | | | | | | | | - Don't use "from copy_reg import *". - Use cls.__module__ instead of calling whichobject(cls, cls.__name__); also try __module__ in whichmodule(), just in case. - After calling save_reduce(), add the object to the memo.
* *Semantic change*: when unpickling the instance variables of anGuido van Rossum1997-09-081-2/+1
| | | | | | | | | | instance, use inst.__dict__.update(value) instead of a for loop with setattr() over the value.keys(). This is more consistent (the pickling doesn't use getattr() either but pickles inst.__dict__) and avoids problems with instances that have a __setattr__ hook. But it *is* a semantic change (because the setattr hook is no longer used). So beware!
* Add the same _keep_alive patch (by Michael Scharff) that was added toGuido van Rossum1997-09-031-0/+19
| | | | | copy.deepcopy() a while ago. Can't reproduce this but it doesn't break anything and it looks like the code could have the same problem.
* Restore two features of the original 1.4 pickle:Guido van Rossum1997-04-251-5/+6
| | | | | | - which_module() search __main__ last; - load_inst() no longer checks that the classname really refers to a class.

* Optimizations and one intentional loophole by Jim Fulton.Guido van Rossum1996-07-221-58/+82
| | | | | | | | | | The optimizations consist mostly of using local variables to cache methods or instance variables used a lot (e.g. "self.write"). The loopholes allows marshalling extension types as long as they have a __class__ attribute (in which case they may support the rest of the class piclking protocol as well). This allows pickling MESS extension types.
* Set the base for atoi() and atol() to 0, since we're reading PythonGuido van Rossum1996-05-151-3/+3

* Don't atoi() the memo key.Guido van Rossum1996-04-121-7/+16
