Description Steve Grubb 2004-09-11 10:47:59 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i586; en-US; rv:1.4.2)

Description of problem:
The hal daemon does not set it pid file.

From configure:

#### Set up the pid file
if ! test -z "$with_pid_file"; then
elif test x$operating_system = xredhat ; then

Let's see where its used:

grep -rl HALD_PID_FILE *

Only the make files and init script uses it.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. service haldaemon stop
2. service haldaemon start

Actual Results:  [root@buildhost root]# service haldaemon stop
Stopping HAL daemon:                                       [FAILED]
[root@buildhost root]# service haldaemon start
Starting HAL daemon:                                       [  OK  ]
/etc/init.d/haldaemon: line 31: /var/run/hald/pid: No such file or

Additional info:

looking deeper into this message: 

/var/run/hald/pid: No such file or directory

The /var/run/hald directory doesn't even exist.

The initscript is responsible for maintaining the pid file and in the
Fedora RPM's the pidfile used is /var/run/ 

If you want to use a different path, then you might need some 'mkdir
-p' stuff in e.g. the %pre section of the RPM file. Or something else.
If you have a patch for the hal.spec to fix this I'll be happy to
apply it.

The initscripts cannot maintain it. How do they know what its pid is
after a fork? All software is supposed to write its own pidfile and
then the initscripts will use it. Stunnel.c is a good & simple example.

Also, the configure should probably be called using: 

>If you have a patch for the hal.spec to fix this I'll be happy

I'll send a patch later. Let me get the pid file being created after
the fork and then we'll see what other fixing up there is.
Comment 3 David Zeuthen 2004-09-12 12:24:54 EDT
OK, I concur, the daemon should be writing the pid file instead.
Awaiting your patch.

Patch to create pid

The least intrusive way to solve this was to add the HALD_PID_FILE define to
config.h and then use it in the hald.c file. I'm testing this patch and it
seems to work fine for me.

I also found the root of some of my problems. The configure script uses
/etc/redhat-release to make some decisions, but that is not a BuildRequires. It
really should be for people doing bootstrap builds. It also helps document what
contributes to the build process.
Comment 5 David Zeuthen 2004-09-16 18:22:00 EDT
Hi, sorry for the lag. I've committed the patch upstream and also
modified the hald/ file which is used as a basis for the
Red Hat initscript. Will close this bug when I've fixed the spec file
and made a new release.

Thanks for the patch,
Comment 6 David Zeuthen 2004-09-21 03:50:36 EDT
I've changed the spec file such that --with-pid-file is passed to
configure - that way we don't rely on /etc/redhat-release for this
package. Available in hal-0.2.98-4.
