Bug 267928 – sys-apps/hal-0.5.12_rc1 hald does not find hald-runner with longer default PATH

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description SpanKY 2009-04-29 22:57:09 UTC]

i have a lot of cross-compilers installed thus:
# echo ${#PATH}
2224

which means when i run hald:
# hald --verbose=yes --daemon=no
18:54:45.677 [I] hald.c:671: hal 0.5.12rc1
18:54:45.677 [I] hald.c:736: Will not daemonize
18:54:45.677 [I] hald_dbus.c:5417: local server is listening at unix:abstract=/var/run/hald/dbus-Ngz5QjsjCl,guid=c10bb6b8b61b898d78c281b749f8dab5
18:54:45.679 [I] ck-tracker.c:391: got seat '/org/freedesktop/ConsoleKit/Seat1'
18:54:45.679 [I] ck-tracker.c:342: Got all sessions on seat '/org/freedesktop/ConsoleKit/Seat1'
18:54:45.679 [I] ck-tracker.c:418: Got seats
18:54:45.679 [I] ck-tracker.c:816: Got seats and sessions
18:54:45.680 [E] hald_runner.c:294: Could not spawn runner : 'Failed to execute child process "hald-runner" (No such file or directory)'

and when i run things through `strace`, it shows clearly that my PATH has been truncated and the critical /usr/libexec/ component has not been added:
# grep hald-runner out
...
18945 execve("/usr/x86_64-pc-linux-gnu//hald-runner", ["hald-runner"], [/* 2 vars */]) = -1 ENOENT (No such file or directory)

there is no "/usr/x86_64-pc-linux-gnu/" in my PATH, but it looks like hald is chopping my PATH at 512 bytes

ive added a workaround to the init.d script in the mean time

Patch removing the PATH 512 byte limit in hald

[Comment 3 Maciej Grela 2009-09-07 20:12:32 UTC]

OP, can you test the attached patch ? It should fix your problem without hacks in the initscript.

It was included by upstream in 0.5.14, then, that version should fix this problem

[Comment 5 SpanKY 2010-02-09 17:15:08 UTC]

hmm, i missed that test request

`/etc/init.d/hald restart` works on my ~amd64 system after dropping the $PATH check, so things look OK now

[Comment 6 Pacho Ramos 2010-02-10 09:02:54 UTC]

Then, I think that this can be closed. Upstream commit is:
http://cgit.freedesktop.org/hal/commit/?id=b296289566a97fa112c7de2fe09389d690841a6a

Best regards

[Comment 7 SpanKY 2010-03-07 06:32:14 UTC]

the PATH hack in the init.d script should be dropped then
