* Fix couple of dead code paths (GH-7418)David Carlier2019-05-171-2/+0
|
* bpo-36946: Fix possible signed integer overflow when handling slices. (GH-13375)Zackery Spytz2019-05-171-1/+2
| | | | | | | The final addition (cur += step) may overflow, so use size_t for "cur". "cur" is always positive (even for negative steps), so it is safe to use size_t here. Co-Authored-By: Martin Panter <vadmium+py@gmail.com>
* bpo-36900: Replace global conf vars with config (GH-13299)Victor Stinner2019-05-141-2/+4
| | | | | | Replace global configuration variables with core_config read from the current interpreter. Cleanup dynload_hpux.c.
* bpo-36254: Fix invalid uses of %d in format strings in C. (GH-12264)Serhiy Storchaka2019-03-131-1/+1
|
* bpo-35552: Fix reading past the end in PyUnicode_FromFormat() and ↵Serhiy Storchaka2019-01-121-3/+9
| | | | | | PyBytes_FromFormat(). (GH-11276) Format characters "%s" and "%V" in PyUnicode_FromFormat() and "%s" in PyBytes_FromFormat() no longer read memory past the limit if precision is specified.
* bpo-33817: Fix _PyBytes_Resize() for empty bytes object. (GH-11516)Serhiy Storchaka2019-01-121-0/+13
| | | | Add also tests for PyUnicode_FromFormat() and PyBytes_FromFormat() with empty result.
* bpo-35444: Unify and optimize the helper for getting a builtin object. ↵Serhiy Storchaka2018-12-111-2/+3
| | | | | | | | (GH-11047) This speeds up pickling of some iterators. This fixes also error handling in pickling methods when fail to look up builtin "getattr".
* bpo-35059: PyObject_INIT() casts to PyObject* (GH-10674)Victor Stinner2018-11-231-3/+3
| | | | | | PyObject_INIT() and PyObject_INIT_VAR() now cast their first argument to PyObject*, as done in Python 3.7. Revert partially commit b4435e20a92af474f117b78b98ddc6f515363af5.
* bpo-35081: Add Include/internal/pycore_object.h (GH-10640)Victor Stinner2018-11-211-0/+1
| | | | Move _PyObject_GC_TRACK() and _PyObject_GC_UNTRACK() from Include/objimpl.h to Include/internal/pycore_object.h.
* bpo-35081: Rename internal headers (GH-10275)Victor Stinner2018-11-121-2/+2
| | | | | | | | | | | | | | Rename Include/internal/ headers: * pycore_hash.h -> pycore_pyhash.h * pycore_lifecycle.h -> pycore_pylifecycle.h * pycore_mem.h -> pycore_pymem.h * pycore_state.h -> pycore_pystate.h Add missing headers to Makefile.pre.in and PCbuild: * pycore_condvar.h. * pycore_hamt.h * pycore_pyhash.h
* bpo-35081: Add pycore_ prefix to internal header files (GH-10263)Victor Stinner2018-10-311-2/+2
| | | | | | | | | | | | | | | | | | | | * Rename Include/internal/ header files: * pyatomic.h -> pycore_atomic.h * ceval.h -> pycore_ceval.h * condvar.h -> pycore_condvar.h * context.h -> pycore_context.h * pygetopt.h -> pycore_getopt.h * gil.h -> pycore_gil.h * hamt.h -> pycore_hamt.h * hash.h -> pycore_hash.h * mem.h -> pycore_mem.h * pystate.h -> pycore_state.h * warnings.h -> pycore_warnings.h * PCbuild project, Makefile.pre.in, Modules/Setup: add the Include/internal/ directory to the search paths of header files. * Update includes. For example, replace #include "internal/mem.h" with #include "pycore_mem.h".
* bpo-35064 prefix smelly symbols that appear with COUNT_ALLOCS with _Py_ ↵Pablo Galindo2018-10-281-5/+5
| | | | | | | (GH-10152) Configuring python with ./configure --with-pydebug CFLAGS="-D COUNT_ALLOCS -O0" makes "make smelly" fail as some symbols were being exported without the "Py_" or "_Py" prefixes.
* bpo-35059: Convert PyObject_INIT() to function (GH-10077)Victor Stinner2018-10-261-3/+3
| | | | | * Convert PyObject_INIT() and PyObject_INIT_VAR() macros to static inline functions. * Fix usage of these functions: cast to PyObject* or PyVarObject*.
* bpo-34984: Improve error messages for bytes and bytearray constructors. ↵Serhiy Storchaka2018-10-211-2/+3
| | | | (GH-9874)
* bpo-34973: Fix crash in bytes constructor. (GH-9841)Serhiy Storchaka2018-10-211-35/+69
| | | Constructing bytes from mutating list could cause a crash.
* bpo-34974: Do not replace unexpected errors in bytes() and bytearray(). ↵Serhiy Storchaka2018-10-141-1/+4
| | | | | | | (GH-9852) bytes and bytearray constructors converted unexpected exceptions (e.g. MemoryError and KeyboardInterrupt) to TypeError.
* bpo-34879: Fix a possible null pointer dereference in bytesobject.c (GH-9683)Zackery Spytz2018-10-031-1/+1
| | | | | formatfloat() was not checking if PyBytes_FromStringAndSize() failed, which could lead to a null pointer dereference in _PyBytes_FormatEx().
* bpo-34436: Fix check that disables overallocation for the last fmt specifier ↵Alexey Izbyshev2018-08-231-3/+3
| | | | | (GH-8826) Reported by Svace static analyzer.
* bpo-34170: Add _PyCoreConfig.bytes_warning (GH-8447)Victor Stinner2018-07-241-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add more fields to _PyCoreConfig: * _check_hash_pycs_mode * bytes_warning * debug * inspect * interactive * legacy_windows_fs_encoding * legacy_windows_stdio * optimization_level * quiet * unbuffered_stdio * user_site_directory * verbose * write_bytecode Changes: * Remove pymain_get_global_config() and pymain_set_global_config() which became useless. These functions have been replaced by _PyCoreConfig_GetGlobalConfig() and _PyCoreConfig_SetGlobalConfig(). * sys.flags.dont_write_bytecode value is now restricted to 1 even if -B option is specified multiple times on the command line. * PyThreadState_Clear() now uses the config from the current interpreter rather than using global Py_VerboseFlag
* bpo-20180: complete AC conversion of Objects/stringlib/transmogrify.h (GH-8039)Tal Einat2018-07-061-7/+5
| | | | * converted bytes methods: expandtabs, ljust, rjust, center, zfill * updated char_convertor to properly set the C default value
* bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. ↵Siddhesh Poyarekar2018-04-291-17/+17
| | | | | | | | | (GH-6030) METH_NOARGS functions need only a single argument but they are cast into a PyCFunction, which takes two arguments. This triggers an invalid function cast warning in gcc8 due to the argument mismatch. Fix this by adding a dummy unused argument.
* bpo-32677: Add .isascii() to str, bytes and bytearray (GH-5342)INADA Naoki2018-01-271-0/+2

* bpo-31338 (#3374)Barry Warsaw2017-09-151-1/+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-30860: Consolidate stateful runtime globals. (#3397)Eric Snow2017-09-081-0/+2
| | | | | | | * 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).

| | | | | | | | | | | | | | | | | | Issue #28858: The change b9c9691c72c5 introduced a regression. It seems like _PyObject_CallArg1() uses more stack memory than PyObject_CallFunctionObjArgs().
* | | Replace PyObject_CallFunctionObjArgs() with fastcallVictor Stinner2016-12-011-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * PyObject_CallFunctionObjArgs(func, NULL) => _PyObject_CallNoArg(func) * PyObject_CallFunctionObjArgs(func, arg, NULL) => _PyObject_CallArg1(func, arg) PyObject_CallFunctionObjArgs() allocates 40 bytes on the C stack and requires extra work to "parse" C arguments to build a C array of PyObject*. _PyObject_CallNoArg() and _PyObject_CallArg1() are simpler and don't allocate memory on the C stack. This change is part of the fastcall project. The change on listsort() is related to the issue #23507.
