Just van Rossum showed a weird, but clever way for pure python code to
trigger the BadInternalCall. The C code had assumed that calling a class
constructor would return an instance of that class; however, classes that
abuse __new__ can invalidate that assumption.
some of the more compilcated cases (CF, Res) haven't been done yet. Also,
various types should inherit from each other (anything with an as_Resource
method should be a Resource subtype, the CF types should become one family).
real module, by filtering out aliased methods. This, combined with
the recent fixes to pyclbr, make it possible to enable more tests with
fewer exceptions.
- The _modules cache now uses the full module name.
- The meaning of the (internal!!!) inpackage argument is changed: it
now is the parent package name, or None. readmodule() doesn't
support this argument any more.
- The meaning of the path argument is changed: when inpackage is set,
the module *must* be found in this path (as is the case for the real
package search).
- Miscellaneous cleanup, e.g. fixed __all__, changed some comments and
doc strings, etc.
- Adapted the unit tests to the new semantics (nothing much changed,
really). Added some debugging code to the unit tests that print
helpful extra info to stderr when a test fails (interpreting the
test failures turned out to be hard without these).
Use OSSAudioError much less frequently -- all real I/O errors (ie. any
time open(), read(), write(), ioctl(), or select() return an error)
become IOError. OSSAudioError is only used now for bad open() mode.
Added _EXPORT_INT macro to export an integer constant to Python-space.
Use it for all the AFMT_* constants, and update the list of AFMT_*
constants to match what's in Linux 2.4: add AFMT_{QUERY,IMA_ADPCM,
MPEG,AC3}. This should probably be tested with older versions of OSS,
eg. with Linux 2.2 and 2.0.
Export all SNDCTL_* ioctl numbers (where "all" is the set found in
/usr/include/linux/soundcard.h on my Debian 3.0 system -- again
Linux 2.4). Again needs to be tested with older OSS versions.
it impossible to access blocking mode!
* Rename write() to writeall(), and add a write() method that just
does one write().
* Rearrange/simplify writeall(): in particular, don't supply a timeout
to select(). Let it block forever if it has to.
* Add a bunch of simple ioctl() wrappers: nonblock(), setfmt(),
getfmts(), channels(), speed(), sync(), reset(), post(). These
wrap, respectively, SNDCTL_DSP_NONBLOCK, SNDCTL_DSP_SETFMT,
SNDCTL_DSP_GETFMTS, etc.
* Reduce flush() (which was a wrapper for the SNDCTL_DSP_SYNC ioctl) to
an alias for sync().
* Rearrange the lad_methods list to reflect the order in which the
methods are defined, and add some grouping comments.
