Gregory P. Smith aa63d0d4af Make file objects as thread safe as the underlying libc FILE* implementation.
close() will now raise an IOError if any operations on the file object
are currently in progress in other threads.

Most code was written by Antoine Pitrou (pitrou).  Additional testing,
documentation and test suite cleanup done by me (gregory.p.smith).

Fixes issue 815646 and 595601 (as well as many other bugs and
references to this problem dating back to the dawn of Python).

Christian Heimes e93237dfcc #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, Py_TYPE and Py_REFCNT. Macros for b/w compatibility are available. 2007-12-19 02:37:44 +00:00
Martin v. Löwis 6819210b9e PEP 3123: Provide forward compatibility with Python 3.0, while keeping
backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
PyVarObject_HEAD_INIT.

Kristján Valur Jónsson 0a440d4184 Export function sanitize_the_mode from fileobject.c as _PyFile_SanitizeMode(). Use this function in posixmodule.c when implementing fdopen(). This fixes test_subprocess.py for a VisualStudio 2005 compile. 2007-04-26 09:15:08 +00:00

Guido van Rossum 7a6e95948c SF patch 580331 by Oren Tirosh: make file objects their own iterator.
For a file f, iter(f) now returns f (unless f is closed), and f.next()
is similar to f.readline() when EOF is not reached; however, f.next()
uses a readahead buffer that messes up the file position, so mixing
f.next() and f.readline() (or other methods) doesn't work right.
Calling f.seek() drops the readahead buffer, but other operations
don't.

The real purpose of this change is to reduce the confusion between
objects and their iterators.  By making a file its own iterator, it's
made clearer that using the iterator modifies the file object's state
(in particular the current position).

A nice side effect is that this speeds up "for line in f:" by not
having to use the xreadlines module.  The f.xreadlines() method is
still supported for backwards compatibility, though it is the same as
iter(f) now.

(I made some cosmetic changes to Oren's code, and added a test for
"file closed" to file_iternext() and file_iter().)

Guido van Rossum a0a6c5a042 Add missing \ to macro definition only used when universal newlines
are disabled.

Tim Peters 058b141ef7 Py_UniversalNewlineFread(): Many changes.
+ Continued looping until n bytes in the buffer have been filled, not
  just when n bytes have been read from the file.  This repairs the
  bug that f.readlines() only sucked up the first 8192 bytes of the file
  on Windows when universal newlines was enabled and f was opened in
  U mode (see Python-Dev -- this was the ultimate cause of the
  test_inspect.py failure).

+ Changed prototye to take a char* buffer (void* doesn't make much sense).

+ Squashed size_t vs int mismatches (in particular, besides the unsigned
  vs signed distinction, size_t may be larger than int).

+ Gets out under all error conditions now (it's possible for fread() to
  suffer an error even if it returns a number larger than 0 -- any
  "short read" is an error or EOF condition).

+ Rearranged and simplified declarations.

Jack Jansen 7b8c7546eb Mass checkin of universal newline support.
Highlights: import and friends will understand any of \r, \n and \r\n
as end of line. Python file input will do the same if you use mode 'U'.
Everything can be disabled by configuring with --without-universal-newlines.

See PEP278 for details.

Martin v. Löwis f6eebbb435 Patch #530105: Allow file object may to be subtyped 2002-03-15 17:42:16 +00:00
Tim Peters c1bbcb87aa PyFile_WriteString(): change prototype so that the string arg is
const char* instead of char*.  The change is conceptually correct, and
indirectly fixes a compiler wng introduced when somebody else innocently
passed a const char* to this function.

Tim Peters 59c9a645e2 SF bug [#460467] file objects should be subclassable.
Preliminary support.  What's here works, but needs fine-tuning.

Guido van Rossum 938178283c new names for lots of new functions 1995-01-17 16:01:01 +00:00
Guido van Rossum caa6380886 The great renaming, phase two: all header files have been updated to
use the new names exclusively, and the linker will see the new names.
Files that import "Python.h" also only see the new names.  Files that
import "allobjects.h" will continue to be able to use the old names,
due to the inclusion (in allobjects.h) of "rename2.h".
1995-01-12 11:45:45 +00:00
Guido van Rossum 5799b52008 Added 1995 copyright.
object.h: made sizes and refcnts signed ints.
stringobject.h: make getstrsize() signed int.
methodobject.h: add METH_VARARGS and METH_FREENAME flag bit definitions.
