| | | | | | | | | | | | guarantee to keep valid pointers in its slots. tests: Moved ExtensionSaver from test_copy_reg into pickletester, and use it both places. Once extension codes get assigned, it won't be safe to overwrite them willy nilly in test suites, and ExtensionSaver does a thorough job of undoing any possible damage. Beefed up the EXT[124] tests a bit, to check the smallest and largest codes in each opcode's range too.
* cPickle now generates proto 2 EXT[124] when appropriate.Tim Peters2003-02-041-2/+67
| | | | | Moved such EXT tests as currently exist from TempAbstractPickleTests to AbstractPickleTests, so that test_cpickle runs them too.

* Rename the extension registry variables to have leading underscores --Guido van Rossum2003-02-041-6/+6
| | | | | | | | | this clarifies that they are part of an internal API (albeit shared between pickle.py, copy_reg.py and cPickle.c). I'd like to do the same for copy_reg.dispatch_table, but worry that it might be used by existing code. This risk doesn't exist for the extension registry.

* Brought some module variables into synch with pickle.py's current values.Tim Peters2003-02-041-16/+47
| | | | | Imported the extension-registry dicts from copy_reg.py, in preparation for tackling EXT[124].

| | | | | | | because it seems more consistent with the rest of the code. cPickle_PyMapping_HasKey(): This extern function isn't used anywhere in Python or Zope, so got rid of it.
* PDATA_PUSH and PDATA_APPEND. documented, and reformatted for betterTim Peters2003-02-031-30/+38
| | | | | | | | | readability. load_bool(): Now that I know the intended difference between _PUSH and _APPEND, used the right one. Pdata_grow(): Squashed out a redundant overflow test.

| | | | | | | | | | | | | | a function, then p->f(arg1, arg2, ...) is semantically the same as (*p->f)(arg1, arg2, ...) Changed all instances of the latter into the former. Given how often the code embeds this kind of expression in an if test, the unnecessary parens and dereferening operator were a real drag on readability.

* dump(): Fixed a stupid bug in new code. It wasn't possible for the bugTim Peters2003-02-021-1/+1
| | | | | to have an effect before protocol 3 is invented, so no test can be written for this (yet).
* Add cPickle support for PROTO. Duplicated PROTO/LONG1/LONG4 code inTim Peters2003-02-021-2/+56
| | | | | the hitherto unknown (to me) noload() cPickle function, which is (a) something we don't test at all, and (b) pickle.py doesn't have.
* cPickle.c: Full support for the new LONG1 and LONG4. Added comments.Tim Peters2003-02-021-21/+161
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Assorted code cleanups; e.g., sizeof(char) is 1 by definition, so there's no need to do things like multiply by sizeof(char) in hairy malloc arguments. Fixed an undetected-overflow bug in readline_file(). longobject.c: Fixed a really stupid bug in the new _PyLong_NumBits. pickle.py: Fixed stupid bug in save_long(): When proto is 2, it wrote LONG1 or LONG4, but forgot to return then -- it went on to append the proto 1 LONG opcode too. Fixed equally stupid cancelling bugs in load_long1() and load_long4(): they *returned* the unpickled long instead of pushing it on the stack. The return values were ignored. Tests passed before only because save_long() pickled the long twice. Fixed bugs in encode_long(). Noted that decode_long() is quadratic-time despite our hopes, because long(string, 16) is still quadratic-time in len(string). It's hex() that's linear-time. I don't know a way to make decode_long() linear-time in Python, short of maybe transforming the 256's-complement bytes into marshal's funky internal format, and letting marshal decode that. It would be more valuable to make long(string, 16) linear time. pickletester.py: Added a global "protocols" vector so tests can try all the protocols in a sane way. Changed test_ints() and test_unicode() to do so. Added a new test_long(), but the tail end of it is disabled because it "takes forever" under pickle.py (but runs very quickly under cPickle: cPickle proto 2 for longs is linear-time).

* Patch #661760: Cygwin auto-import module patchJason Tishler2003-01-061-4/+2
| | | | | | | | | | | | The attached patch enables shared extension modules to build cleanly under Cygwin without moving the static initialization of certain function pointers (i.e., ones exported from the Python DLL core) to a module initialization function. Additionally, this patch fixes the modules that have been changed in the past to accommodate Cygwin.

* Fix indentation.Jeremy Hylton2002-07-181-5/+5

* staticforward bites the dust.Jeremy Hylton2002-07-171-2/+2
| | | | | | | | | | | | | | | The staticforward define was needed to support certain broken C compilers (notably SCO ODT 3.0, perhaps early AIX as well) botched the static keyword when it was used with a forward declaration of a static initialized structure. Standard C allows the forward declaration with static, and we've decided to stop catering to broken C compilers. (In fact, we expect that the compilers are all fixed eight years later.) I'm leaving staticforward and statichere defined in object.h as static. This is only for backwards compatibility with C extensions that might still use it. XXX I haven't updated the documentation.
* Given the persistent id code a shot at a class before calling save_global().Jeremy Hylton2002-07-161-5/+5
| | | | | Some persistent picklers (well, probably, the *only* persistent pickler) would like to pickle some classes in a special way.

* Do more robust test of whether global objects are accessible.Jeremy Hylton2002-07-111-4/+3
| | | | | | | | PyImport_ImportModule() is not guaranteed to return a module object. When another type of object was returned, the PyModule_GetDict() call return NULL and the subsequent GetItem() seg faulted. Bug fix candidate.

* Repair widespread misuse of _PyString_Resize. Since it's clear peopleTim Peters2002-04-271-7/+1
| | | | | | | | | | | | | | | | | | | | | | don't understand how this function works, also beefed up the docs. The most common usage error is of this form (often spread out across gotos): if (_PyString_Resize(&s, n) < 0) { Py_DECREF(s); s = NULL; goto outtahere; } The error is that if _PyString_Resize runs out of memory, it automatically decrefs the input string object s (which also deallocates it, since its refcount must be 1 upon entry), and sets s to NULL. So if the "if" branch ever triggers, it's an error to call Py_DECREF(s): s is already NULL! A correct way to write the above is the simpler (and intended) if (_PyString_Resize(&s, n) < 0) goto outtahere; Bugfix candidate.
