This is inspired by SF patch 581742 (by Jonathan Hogg, who also
submitted the bug report, and two other suggested patches), but
separates the non-GC case from the GC case to avoid testing for GC
several times.
Had to fix an assert() from call_finalizer() that asserted that the
object wasn't untracked, because it's possible that the object isn't
GC'ed!
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().)
if we are running in an OSX framework enabled build directory, test that
the framework infrastructure exists. This catches the very common
error of doing "make install" in stead of "make frameworkinstall".
at compile time: use PBGetCatInfoSync() to get FInfo data in stead of
GetFInfo. The latter doesn't work for folders. The former does, at
least on OSX, and insofar the info makes sense for a folder.
setup.py (indirectly) script to build the standard dynamically loaded
modules, the errno module is being made static so it will always be
available.
Closes SF bug #591205 (needed on trunk only).
1) Do not attempt to exec a file which does not exist
just to find out what error the operating system
returns. This is an exploitable race on all platforms
that support symbolic links.
2) Immediately re-raise the exception if we get an
error other than errno.ENOENT or errno.ENOTDIR. This
may need to be adapted for other platforms.
(As a security issue, this should be considered for 2.1
and 2.2 as well as 2.3.)
where it was: it is really a configuration file, not a normal module.
By moving it into Mac/Lib we can now also store the location of bgen
itself in there, which is needed because bgen isn't installed.
