Support for the new -U command line option option:
with the option enabled the Python compiler
interprets all "..." strings as u"..." (same with r"..." and
ur"...").
utime(path, NULL) call, setting the atime and mtime of the file to the
current time. The previous signature utime(path, (atime, mtime)) is
of course still allowed.
Follow a suggestion in an /*XXX*/ comment [in com_add()] to speed up
compilation by using supplemental dictionaries to keep track of names
and constants, eliminating quadratic behavior. With this patch in
place, the time to import a 5000-line file with lots of constants [at
the global level] is reduced from 20 seconds to under 3 on my system.
Here's a patch which changes modsupport to add 'u' and 'u#',
to support building Unicode objects from a null-terminated
Py_UNICODE *, and a Py_UNICODE * with length, respectively.
[Conversion from 'U' to 'u' by Fred, based on python-dev comments.]
Note that the use of None for NULL values of the Py_UNICODE* value is
still in; I'm not sure of the conclusion on that issue.
remaining object references if the environment variable PYTHONDUMPREFS
exists. The default behaviour caused problems for background or
otherwise invisible processes that use the debug build of Python.
Fixed a reference leak in the allocator.
Renamed utf8_string to _PyUnicode_AsUTF8String() and made
it external for use by other parts of the interpreter.
Fixed a memory leak found by Fredrik Lundh. Instead of
PyUnicode_AsUTF8String() we now use _PyUnicode_AsUTF8String() which
returns the string object without incremented refcount (and assures
that the so obtained object remains alive until the Unicode object is
garbage collected).
even if it's already absolute. Currently only implemented for Unix; I'm
not entirely sure of the right thing to do for DOS/Windows, and have no
clue what to do for Mac OS.
This patch is a workaround for Macintosh, where the GUSI I/O library
(time, stat, etc) use the MacOS epoch of 1-Jan-1904 and the MSL C
library (ctime, localtime, etc) uses the (apparently ANSI standard)
epoch of 1-Jan-1900. Python programs see the MacOS epoch and we
convert values when needed.
The previous checkin (2.84) added a PyErr_Format call that made the
cost of raising an AttributeError much more expensive. In general
this doesn't matter, except that checks for __init__ and
__del__ methods, where exceptions are caught and cleared in C, also
got much more expensive.
The fix is to split instance_getattr1 into two calls:
instance_getattr2 checks the instance and the class for the attribute
and returns it or returns NULL on error. It does not raise an
exception.
instance_getattr1 does rexec checks, then calls instance_getattr2. It
raises an exception if instance_getattr2 returns NULL.
PyInstance_New and instance_dealloc now call instance_getattr2
directly.
This patch changes posixmodule.c:execv to
a) check for zero length args (does this to execve, too), raising
ValueError.
b) raises more rational exceptions for various flavours of duff arguments.
I *hate*
TypeError: "illegal argument type for built-in operation"
It has to be one of the most frustrating error messages ever.
get_rfc_url(): New function; returns the URL for a numbered IETF RFC.
do_cmd_rfc(): Use get_rfc_url() instead of hard-coding in the HTML
formatting.
do_cmd_seerfc(): New function.
do_env_definitions(): Small change to avoid "local".
in command-line options, and in two phases at that: first, we expand
'install_base' and 'install_platbase', and then the other 'install_*'
options. This lets us do tricky stuff like
install --prefix='/tmp$sys_prefix'
...oooh, neat.
Simplified 'select_scheme()' -- it's no longer responsible for expanding
config vars, tildes, etc.
Define installation-specific config vars in 'self.config_vars', rather than
in a local dictionary of one method. Also factored '_expand_attrs()' out
of 'expand_dirs()' and added 'expand_basedirs()'.
Added a bunch of debugging output so I (and others) can judge the
success of this crazy scheme through direct feedback.
