Prepared a patch + but it's not good. +* [glib's garray test timeouts on Hurd](https://bugzilla.gnome.org/show_bug.cgi?id=568760). + The tests passes if the timeout is increased. The current upstream timeout + (10s) is quite small (it fails on many Debian builds for some Linux arches). + However on Hurd it needs a very big time it seems (like more than 100s). + Maybe do an allocation benchmarch? +* Investigated glib's unix-fd test failure: getsockopt() isn't implemented + on Hurd. Need to implement it in hurd/pflocal/socket.c. +* Investigated coreutils' ln EIEIO, with Samuel's help. linkat() is buggy. + Reported as [bug 29655](https://savannah.gnu.org/bugs/?29655). Prepared a + patch, waiting on the copyright paperwork before submitting it to libc-alpha. + Got part of it already (committed)[http://sources.redhat.com/ml/libc-alpha/2010-04/msg00046.html]. +* Investigated coreutils' cp EACCES. Test case: 'mkfifo a && cp -R --copy-contents a b'. + Problem is that O_NOFOLLOW adds O_NOTRANS. + + +### April 28 - May 5 +* Submitted a talk proposal on Hurd with Michael Banck for DebConf +* Sent request to assign copyright to the FSF for Hurd/Mach/libc + +### May 5 - May 12 +* Read http://www.gnu.org/software/hurd/hurd-paper.html +* Improved the linkat() patch +* Fixed the issues mentioned in bug 28934, but after doing so I realized + that wouldn't work well. The only good solution is to pass file_name + from execve() to the exec server, so we need new RPCs. + +### May 12 - May 19 +* Read http://www.gnu.org/software/hurd/hurd-talk.html +* Half read http://www.gnu.org/software/hurd/hacking-guide/hhg.html +* Read many Hurd interfaces (fs.defs, auth.defs, fsys.defs, io.defs, + password.defs). + + +## TODO + + +## Documentation +* [Towards a New Strategy of OS Design, an architectural overview by Thomas Bushnell, BSG](http://www.gnu.org/software/hurd/hurd-paper.html) +* [The Hurd, a presentation by Marcus Brinkmann](http://www.gnu.org/software/hurd/hurd-talk.html) +* [The Hurd Hacking Guide](http://www.gnu.org/software/hurd/hacking-guide/hhg.html) |
