of three macros, one which replaces some of the current conventions used in
the module sections:
\declaremodule: Requires two parameters: module type (standard, builtin,
extension), and the module name. An optional parameter should be
given as the basis for the module's "key" used for linking to or
referencing the section. The "key" should only be given if the
module's name contains underscores, and should be the name with the
underscore's stripped. This should be the first thing after the
\section used to introduce the module.
\modulesynopsis: Requires a single parameter: a short, one-liner
description of the module that can be used as part of the chapter
introduction. This should probably be placed just after the
\declaremodule, but may be placed anywhere in the same section.
\localmoduletable: No parameters. If a .syn file exists for the current
chapter (or for the entire document in howto docs), a synopsistable
is created with the contents loaded from the .syn file.
Some re-organization due to module synopsis support.
Some \def's changed to \newcommand's.
exceptions:
posix_error_with_filename(): New function which calls
PyErr_SetFromErrnoWithFilename()
The following methods have been changed to call
posix_error_with_filename():
posix_1str()
posix_strint()
posix_strintint()
posix_do_stat()
posix_mkdir()
posix_utime()
posix_readlink()
posix_open()
INITFUNC(): os.error (nee PosixError) is PyExc_OSError
an exception from errno, with a supplied filename (primarily used by
IOError and OSError). If class exceptions are used then the exception
is instantiated with a 3-tuple: (errno, strerror, filename). For
backwards compatibility reasons, if string exceptions are used,
filename is ignored.
PyErr_SetFromErrno(): Implement in terms of
PyErr_SetFromErrnoWithFilename().
involve a filesystem path. To that end:
- Changed IOError to EnvironmentError and added a hack which checks
for arg of len 3. When constructed with a 3-tuple, the third item
is the filename and this is squirreled away in the `filename'
attribute. However, for in-place unpacking backwards
compatibility, self.args still only gets the first two items. Added
a __str__() which prints the filename if it is given.
- IOError now inherits from EnvironmentError
- New class OSError which also inherits from EnvironmentError and is
used by the posix module.
OSError. The EnvironmentError serves primarily as the (common
implementation) base class for IOError and OSError. OSError is used
by posixmodule.c
Also added tuple definition of EnvironmentError when using string
based exceptions.
Fix the implementation of quote_plus(). (It wouldn't treat '+' in the
original data right.)
Add urlencode(dict) which is handy to create the data for sending a
POST request with urlopen().
before calling it. This check was there when the objects were of the
same type *before* coercion, but not if they initially differed but
became the same *after* coercion.
according to an idea by Harri Pasanen (but with different syntax).
This affects the 'break' and 'clear' commands and their help
functions. Also added a helper method lookupmodule().
Also:
- Try to import readline (important when pdb is used from/as a script).
- Get rid of reference to ancient __privileged__ magic variable.
- Moved all import out of functions to the top.
- When used as a script, check that the script file exists.
not calling self.search(); instead, call self.code.match() directly
and interpret the list of registers it returns directly. This saves
the overhead of instantiating a MatchObject for each hit, basically
inlining search() as well as group(). When a MatchObject is still
needed, one is allocated and reused for the duration of the scan.
Sparc Solaris 2.6 (fully patched!) that I don't want to dig into, but
which I suspect is a bug in the multithreaded malloc library that only
shows up when run on a multiprocessor. (The program wasn't using
threads, it was just using the multithreaded C library.)
In the bbox method of Group (Canvas.py file), you should read
return self.canvas._getints(self._do('bbox'))
instead of
return self._getints(self._do('bbox'))
low-level Python exit handler. This can attempt to call Python code
at a point that the interpreter and thread state have already been
destroyed, causing a Bus Error. Given the intended use of
Py_AtExit(), I'm not convinced that it's a good idea to call it
earlier during Python's finalization sequence... (Although this is
the only use for it in the entire distribution.)
create the preferences file. This is so that frozen programs don't
interfere with an existing Python installation, or leave turds in the
Preferences folder.
There's also new support for importing code fragments: if a file on
sys.path contains a PYD resource with resourcename equal to the name
of the module to be imported this PYD resource should contain a
(pascal) string with the name of a code fragment to load. This allows
freezing Python programs without access to source or a development
environment.
