[Allow tests to be divided into generic, and uuu-only tests
Phil Frost <indigo@xxxxxxxxxxx>**20050304005014
With this, it is possible to run only the tests that are expected to pass on
any python platform.
]
[remove now unneeded uuu.thread
Phil Frost <indigo@xxxxxxxxxxx>**20050303180928
The only thing this did was provide read_usec_timer() to snap, and snap no
longer needs this as it uses gettimeofday().
]
[write tests for some known problems
Phil Frost <indigo@xxxxxxxxxxx>**20050303162652]
[create uuu.test.uuunittest, like unittest, but better.
Phil Frost <indigo@xxxxxxxxxxx>**20050303161719
Most importantly, this allows tests to be skipped, or to be marked as expected
to fail.
]
[add options to save builds from test process
Phil Frost <indigo@xxxxxxxxxxx>**20050303032042
This is useful especially for publishing builds on the unununium.org website.
]
[make 'stty sane' command failure when running tests non-fatal
Phil Frost <indigo@xxxxxxxxxxx>**20050302200546
"stty sane" fails when stdout isn't a tty. Ignore that failure.
]
[add a testing framework
Phil Frost <indigo@xxxxxxxxxxx>**20050302141302
It has yet no tests, but is otherwise complete.
]
[By default search for oskit in /usr then /usr/local.
Phil Frost <indigo@xxxxxxxxxxx>**20050302135209
This should eliminate the need to manually configure oskitprefix for many
people.
]
[Crank the stack size up to 2 Mib
Phil Frost <indigo@xxxxxxxxxxx>**20050301041748
This makes the recently developed hacks to get twisted to run unneeded.
Hopefully, it will reduce the frequency of random crashing, too.
]
[add some commands to the shell for playing with twisted
Phil Frost <indigo@xxxxxxxxxxx>**20050228170747]
[Build more standard python C extension as shared objects
Phil Frost <indigo@xxxxxxxxxxx>**20050228113447]
[slightly more useful error message when getting the working directory for the
prompt
Phil Frost <indigo@xxxxxxxxxxx>**20050228101913
This is broken in oskit, somehow. Rather than fix oskit, make the error more
obvious by printing the exception in the prompt, rather than just '???'
]
[get rid of siginterrupt; python has been made to not need it
Phil Frost <indigo@xxxxxxxxxxx>**20050228094326]
[use build-conf.py to set build options
Phil Frost <indigo@xxxxxxxxxxx>**20050227054613]
[fix some directory handling errors in the (now unused) ext2 module
Phil Frost <indigo@xxxxxxxxxxx>**20050220052356]
[wrap oskit.blkio objects in process locks
Phil Frost <indigo@xxxxxxxxxxx>**20050220050141
Somehow I fear there are a dozen more things that need locks around them. Tried
putting them around the filesystem, which made qemu crash. Locking just the
blkio seems to make the bootable cd images work on hardware.
]
[tweak bootable CD build
Phil Frost <indigo@xxxxxxxxxxx>**20050220012030
- Use long filenames instead of 8.3 DOS crap in addition to rock ridge
extensions.
- Don't include the release string as a dependency, so the image is not rebuilt
when nothing has changed.
]
[make scons always complain when oskitprefix is not right
Phil Frost <indigo@xxxxxxxxxxx>**20050219234503]
[include a release identifier in bootable cd images
Phil Frost <indigo@xxxxxxxxxxx>**20050219174756]
[update documentation, and change cd build target from 'iso' to 'cd'.
Phil Frost <indigo@xxxxxxxxxxx>**20050219173830]
[add 'iso' build target, and make fixes to allow it to be mounted
Phil Frost <indigo@xxxxxxxxxxx>**20050219165356]
[link snap libs against the extension modules, instead of the core.
Phil Frost <indigo@xxxxxxxxxxx>**20041220140008]
[add a working, but minimal irc client
Phil Frost <indigo@xxxxxxxxxxx>**20050119134618
To use, create an instance of uuu.irc.Client and call its mainloop method, or
use the 'irc' command in the shell.
]
[enable the oskit fancy-console
Phil Frost <indigo@xxxxxxxxxxx>**20050119133050]
[fix printf declaration in interrupts.pyx
Phil Frost <indigo@xxxxxxxxxxx>**20050119012725]
[abort the build if the oskit symlink can not be created
Phil Frost <indigo@xxxxxxxxxxx>**20050118151304]
[enable networking; it works
Phil Frost <indigo@xxxxxxxxxxx>**20050116235346]
[kill unused make_interrupt_handler()
Phil Frost <indigo@xxxxxxxxxxx>**20050116184252]

Phil Frost <indigo@xxxxxxxxxxx>**20041224133729]
[clean up arch/ia32 directory
Phil Frost <indigo@xxxxxxxxxxx>**20041218132337]
[add python stdlib to install targets
Phil Frost <indigo@xxxxxxxxxxx>**20041219211532]
[add README in two flavors
Phil Frost <indigo@xxxxxxxxxxx>**20041217015848]
[add help on available options
Phil Frost <indigo@xxxxxxxxxxx>**20041216185004]
[mega rearangement of source and build system
Phil Frost <indigo@xxxxxxxxxxx>**20041216140636
- python modules are easier to integrate to the build and have installed
- option 'debug' to include debug symbols or not. Builds go in different
directories.
- remove src/, moving things to top level
- make build system has been made less centralized and more readable
- delete old crufty code
]
[don't load modules if possible at boot
Phil Frost <indigo@xxxxxxxxxxx>**20041215220026
Now that filesystem is provided by oskit, getting a filesystem working has less
bootstrap mess. Also, the last patch added a runtime linker, so now C
extensions can be loaded.
There is a new option INSTALLDIR which gives a directory to install all the
stuff. An alias 'install' now exists to install unununium.o and the uuu modules
to that directory.
]
[give unununium the power to load shared libs with dlopen and friends
Phil Frost <indigo@xxxxxxxxxxx>**20041215130406]
[fix path to python modules loaded at init
Phil Frost <indigo@xxxxxxxxxxx>**20041215130131]
[make shell.py use standard os module interface for file manipulation
Phil Frost <indigo@xxxxxxxxxxx>**20041212015448
oskit now provides filesystem functionality, and the old VFS interface is no
longer used.
]
["fix on the timming at thread.pyx"
alphakiller@xxxxxxxxxxxxx**20041212015751]
[move undefined symbol hacks to a separate file, undefined_symbols.c
Phil Frost <indigo@xxxxxxxxxxx>**20041212044600]
[oskit wrapper cleanup; release references when done
Phil Frost <indigo@xxxxxxxxxxx>**20041212044427]
[disable network init for now, until it works
Phil Frost <indigo@xxxxxxxxxxx>**20041212042729]
[remove some old cruft
Phil Frost <indigo@xxxxxxxxxxx>**20041212030336]
[remove src/lib/c
Phil Frost <indigo@xxxxxxxxxxx>**20041212011153
this was a modified version of dietlibc, but is no longer needed as oskit
provides the C library.
