* bpo-32746: Fix multiple typos (GH-5144)Leo Arias2018-02-041-1/+1
| | | Fix typos found by codespell in docs, docstrings, and comments.
* bpo-32571: Avoid raising unneeded AttributeError and silencing it in C code ↵Serhiy Storchaka2018-01-251-92/+47
| | | | | (GH-5222) Add two new private APIs: _PyObject_LookupAttr() and _PyObject_LookupAttrId()
* bpo-32503: Avoid creating too small frames in pickles. (#5127)Serhiy Storchaka2018-01-201-9/+9

* bpo-31993: Do not use memoryview when pickle large strings. (#5154)Serhiy Storchaka2018-01-121-2/+3
| | | | | | PyMemoryView_FromMemory() created a memoryview referring to the internal data of the string. When the string is destroyed the memoryview become referring to a freed memory.
* bpo-31993: Do not create frames for large bytes and str objects (#5114)Serhiy Storchaka2018-01-111-94/+86
| | | | | | | when serialize into memory buffer with C pickle implementations. This optimization already is performed when serialize into memory with Python pickle implementations or into a file with both implementations.
* bpo-31993: Do not allocate large temporary buffers in pickle dump. (#4353)Olivier Grisel2018-01-061-24/+114
| | | | | | | | | | | | | | | | | The picklers do no longer allocate temporary memory when dumping large bytes and str objects into a file object. Instead the data is directly streamed into the underlying file object. Previously the C implementation would buffer all content and issue a single call to file.write() at the end of the dump. With protocol 4 this behavior has changed to issue one call to file.write() per frame. The Python pickler with protocol 4 now dumps each frame content as a memoryview to an IOBytes instance that is never reused and the memoryview is no longer released after the call to write. This makes it possible for the file object to delay access to the memoryview of previous frames without forcing any additional memory copy as was already possible with the C pickler.
* bpo-28416: Break reference cycles in Pickler and Unpickler subclasses (#4080)Serhiy Storchaka2017-11-301-38/+98
| | | | with the persistent_id() and persistent_load() methods.
* bpo-32037: Use the INT opcode for 32-bit integers in protocol 0 pickles. (#4407)Serhiy Storchaka2017-11-161-23/+23

* bpo-32013: _pickle: Add missing Py_DECREF in error case in fast_save_enter() ↵Mat M2017-11-131-1/+5
| | | | (#4384)
* bpo-31572: Get rid of using _PyObject_HasAttrId() in pickle. (#3729)Serhiy Storchaka2017-10-221-30/+33

* bpo-28411: Support other mappings in PyInterpreterState.modules. (#3593)Eric Snow2017-09-151-39/+68
| | | | | The concrete PyDict_* API is used to interact with PyInterpreterState.modules in a number of places. This isn't compatible with all dict subclasses, nor with other Mapping implementations. This patch switches the concrete API usage to the corresponding abstract API calls. We also add a PyImport_GetModule() function (and some other helpers) to reduce a bunch of code duplication.
* bpo-31338 (#3374)Barry Warsaw2017-09-151-2/+1
| | | | | | | * Add Py_UNREACHABLE() as an alias to abort(). * Use Py_UNREACHABLE() instead of assert(0) * Convert more unreachable code to use Py_UNREACHABLE() * Document Py_UNREACHABLE() and a few other macros.
* bpo-31404: Revert "remove modules from Py_InterpreterState (#1638)" (#3565)Eric Snow2017-09-141-2/+10
| | | PR #1638, for bpo-28411, causes problems in some (very) edge cases. Until that gets sorted out, we're reverting the merge. PR #3506, a fix on top of #1638, is also getting reverted.
* bpo-30860: Move windows.h include out of internal/*.h. (#3458)Eric Snow2017-09-121-1/+1
| | | PR #3397 introduced a large number of warnings to the Windows build. This patch fixes them.
* bpo-30860: Consolidate stateful runtime globals. (#3397)Eric Snow2017-09-081-0/+7
| | | | | | | * group the (stateful) runtime globals into various topical structs * consolidate the topical structs under a single top-level _PyRuntimeState struct * add a check-c-globals.py script that helps identify runtime globals Other globals are excluded (see globals.txt and check-c-globals.py).
* _pickle: Fix whichmodule() (#3358)Victor Stinner2017-09-051-1/+1
| | | | | | _PyUnicode_FromId() can return NULL: replace Py_INCREF() with Py_XINCREF(). Fix coverity report: CID 1417269.
* bpo-28411: Remove "modules" field from Py_InterpreterState. (#1638)Eric Snow2017-09-041-10/+2
| | | sys.modules is the one true source.
* bpo-29865: Use PyXXX_GET_SIZE macros rather than Py_SIZE for concrete types. ↵Serhiy Storchaka2017-03-211-9/+9

* Issue #29368: Fix _Pickle_FastCall() usage in do_append()Victor Stinner2017-02-021-1/+0
| | | | | _Pickle_FastCall() has a surprising API: it decrements the reference counter of its second argument.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Issue #28915: Replace _PyObject_CallMethodId() with _PyObject_CallMethodIdObjArgs() in various modules when the format string was only made of "O" formats, PyObject* arguments. _PyObject_CallMethodIdObjArgs() avoids the creation of a temporary tuple and doesn't have to parse a format string.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace _PyObject_CallArg1(func, arg) with PyObject_CallFunctionObjArgs(func, arg, NULL) Using the _PyObject_CallArg1() macro increases the usage of the C stack, which was unexpected and unwanted. PyObject_CallFunctionObjArgs() doesn't have this issue.

* | Avoid inefficient way to call functions without argumentVictor Stinner2016-09-061-1/+1
