* bpo-35133: Fix mistakes when concatenate string literals on different lines. ↵Serhiy Storchaka2018-11-051-1/+1
| | | | | | | | | | (GH-10284) Two kind of mistakes: 1. Missed space. After concatenating there is no space between words. 2. Missed comma. Causes unintentional concatenating in a list of strings.
* bpo-35081: Move accu.h to Include/internal/pycore_accu.h (GH-10271)Victor Stinner2018-11-011-1/+1
| | | | | | | The accu.h header is no longer part of the Python C API: it has been moved to the "internal" headers which are restricted to Python itself. Replace #include "accu.h" with #include "pycore_accu.h".
* bpo-35081: Add pycore_ prefix to internal header files (GH-10263)Victor Stinner2018-10-311-1/+1
| | | | | | | | | | | | | | | | | | | | * 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-35062: Fix parsing _io.IncrementalNewlineDecoder's *translate* argument. ↵Xiang Zhang2018-10-311-1/+1
| | | | | | (GH-10217) _io.IncrementalNewlineDecoder's initializer possibly assigns out-of-range value to the bitwise struct field.

* bpo-32236: open() emits RuntimeWarning if buffering=1 for binary mode (GH-4842)Alexey Izbyshev2018-10-201-0/+9
| | | | | | | | | If buffering=1 is specified for open() in binary mode, it is silently treated as buffering=-1 (i.e., the default buffer size). Coupled with the fact that line buffering is always supported in Python 2, such behavior caused several issues (e.g., bpo-10344, bpo-21332). Warn that line buffering is not supported if open() is called with binary mode and buffering=1.
* bpo-34070: open() only checks for isatty if buffering < 0 (GH-8187)David Herberth2018-10-191-3/+3
|
* bpo-24658: Fix read/write greater than 2 GiB on macOS (GH-1705)Stéphane Wirtel2018-10-171-5/+3
| | | On macOS, fix reading from and writing into a file with a size larger than 2 GiB.

* bpo-25862: Fix several bugs in the _io module. (GH-8026)Serhiy Storchaka2018-06-302-8/+17
| | | | | | | | | | | They can be exposed when some C API calls fail due to lack of memory. * Failed Py_BuildValue() could cause an assertion error in the following TextIOWrapper.tell(). * input_chunk could be decrefed twice in TextIOWrapper.seek() after failed Py_BuildValue(). * initvalue could leak in StringIO.__getstate__() after failed PyDict_Copy().
* bpo-25862: Fix assertion failures in io.TextIOWrapper.tell(). (GH-3918)Zackery Spytz2018-06-291-0/+5
|
* Fix Windows build of Python for latest WinSDK. (GH-6874)Carl Meyer2018-05-171-1/+1
|
* bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. ↵Siddhesh Poyarekar2018-04-295-6/+6
| | | | | | | | | (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-31966: Fixed WindowsConsoleIO.write() for writing empty data. (GH-5754)Serhiy Storchaka2018-02-241-0/+3

* bpo-32228: Reset raw_pos after unwinding the raw stream (#4858)Nitish Chandra2018-01-281-4/+10
| | | Ensure that ``truncate()`` preserves the file position (as reported by ``tell()``) after writes longer than the buffer size.
* bpo-32571: Avoid raising unneeded AttributeError and silencing it in C code ↵Serhiy Storchaka2018-01-254-64/+37
| | | | | (GH-5222) Add two new private APIs: _PyObject_LookupAttr() and _PyObject_LookupAttrId()

* bpo-32186: Release the GIL during lseek and fstat (#4652)Nir Soffer2017-12-011-1/+5
| | | | | | In _io_FileIO_readall_impl(), lseek() and _Py_fstat_noraise() were called without releasing the GIL. This can cause all threads to hang for unlimited time when calling FileIO.read() and the NFS server is not accessible.
* bpo-31976: Fix race condition when flushing a file is slow. (#4331)benfogle2017-11-101-5/+9
|
* Replace KB unit with KiB (#4293)Victor Stinner2017-11-082-2/+2
| | | | | | | | | | | kB (*kilo* byte) unit means 1000 bytes, whereas KiB ("kibibyte") means 1024 bytes. KB was misused: replace kB or KB with KiB when appropriate. Same change for MB and GB which become MiB and GiB. Change the output of Tools/iobench/iobench.py. Round also the size of the documentation from 5.5 MB to 5 MiB.
* bpo-25359: Add missed "goto error" after setting an exception. (#3712)Serhiy Storchaka2017-09-231-0/+1

* bpo-17852: Maintain a list of BufferedWriter objects. Flush them on exit. ↵Neil Schemenauer2017-09-223-1/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (#3372) * Maintain a list of BufferedWriter objects. Flush them on exit. In Python 3, the buffer and the underlying file object are separate and so the order in which objects are finalized matters. This is unlike Python 2 where the file and buffer were a single object and finalization was done for both at the same time. In Python 3, if the file is finalized and closed before the buffer then the data in the buffer is lost. This change adds a doubly linked list of open file buffers. An atexit hook ensures they are flushed before proceeding with interpreter shutdown. This is addition does not remove the need to properly close files as there are other reasons why buffered data could get lost during finalization. Initial patch by Armin Rigo. * Use weakref.WeakSet instead of WeakKeyDictionary. * Simplify buffered double-linked list types. * In _flush_all_writers(), suppress errors from flush(). * Remove NEWS entry, use blurb. * Take more care when flushing file buffers from atexit. The previous implementation was not careful enough to avoid causing issues in multi-threaded cases. Check for buf->ok and buf->finalizing before actually doing the flush. Also, increase the refcnt to ensure the object does not disappear.
* bpo-30860: Consolidate stateful runtime globals. (#3397)Eric Snow2017-09-081-1/+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).

| | | | | | | | The function '_PyArg_ParseStack()' and '_PyArg_UnpackStack' were failing (with error "XXX() takes Y argument (Z given)") before the function '_PyArg_NoStackKeywords()' was called. Thus, the latter did not raise its more meaningful error : "XXX() takes no keyword arguments".
