Can you run 'ls -la /var/lib/mlocate'

# ls -la /var/lib/mlocate
drwxr-x--- 2 root slocate 80 2007-04-13 19:19 .
drwxr-xr-x 11 root root 296 2007-04-13 19:19 ..
-rw-r----- 1 root mlocate 2303261 2007-04-13 19:19 mlocate.db

Hm... Shouldn't mlocate.db be writeable for mlocate group? ;)

ok somethings gone foo bar :-/

'grep locate /etc/groups' please

The mlocate and slocate groups share the same gid, but slocate should have been removed from /etc/groups when you removed slocate.

Roman: No only readable, the problem is /usr/bin/locate and /var/lib/mlocate are root:slocate, they should be root:mlocate

$ grep locate /etc/group
slocate:x:21:
mlocate:x:101:

I also have another machine with the older version of mlocate on it (0.15-1). There is no /var/lib/mlocate on that machine, only /var/lib/slocate. On that machine,
# ls -al /var/lib/slocate/
total 653
drwxr-x--- 2 root mlocate 80 2007-03-19 21:50 .
drwxr-xr-x 8 root root 224 2007-03-26 06:35 ..
-rw-r----- 1 root mlocate 666372 2007-03-19 21:50 slocate.db

and
$ grep locate /etc/group
mlocate:x:21:

I think one locate group would be ok for slocate/mlocate/rlocate packages, wouldn't it?

Strange, not sure how it's ended up in this state. As far as I know it's never used /var/lib/slocate.

As root run 'groupdel slocate ; pacman -S mlocate' and agree to reinstall mlocate, this should fix the permission problems.

Roman; Your right, they all have the same gid according, might as well make it the same group name.

I removed the slocate group and reinstalled mlocate. The same problem persists.
$ grep locate /etc/group
mlocate:x:101:

# ls -al /var/lib/mlocate/
total 2254
drwxr-x--- 2 root 21 80 2007-04-13 19:52 .
drwxr-xr-x 11 root root 296 2007-04-13 19:51 ..
-rw-r----- 1 root mlocate 2303329 2007-04-13 19:52 mlocate.db

group 21 was the slocate group id. Should it now be 101, or perhaps mlocate should be group 21?

mlocate should be gid 21, and there should be no slocate group in /etc/groups.

Where did you get the mlocate package from?

Well, slocate is gone (since I deleted the group), but mlocate is not group 21.

The mlocate package comes from http://mirror.cs.vt.edu/pub/ArchLinux/extra/os/i686

It's the package (mlocate-0.16-1.pkg.tar.gz) that's broken not the PKGBUILD.

To fix your system run (as root)
chown root:mlocate /usr/bin/locate /var/lib/mlocate /var/lib/mlocate.db

I'll submit a patch for *locate to follow Roman's suggestion and switch to one group called locate for all *locate packages.

Thanks! Things are working properly now.

Interestingly, I removed mlocate, deleted the mlocate group, and then reinstalled mlocate. The mlocate group was then created with the correct group id, 21.

patches to tidy up {s,m}locate, both now use the same group (locate gid 21). I've added some code to post_upgrade to fix permissions/groups.

Also there's no need to distribute an empty {s,m}locate.db, updatedb sets the correct permissions on the file when it creates/updates it, and both {s,m}locate return errors when the file is zero length.

A request to re-open the task has been made by Andrew Fyfe (space-m0nkey).
Reason for request: Can you also apply the slocate patch please.

mlocate command is technically locate, but slocate is symlinked and still works.
You should run updatedb as root.
[root@sawernew borje4]# chown root:mlocate /usr/bin/locate /var/lib/mlocate /var/lib/mlocate.db
chown: `root:mlocate': invalid group

linfan

There's no need to run the chown command mlocate-0.16-2 has been fixed.

The mlocate group (and slocate group once it's patched), no longer exist, they've been replaced by a single group named locate.

that meant that you manually have to remove the slocate from /etc/group - will try that
linfan

Did not work still get: updatedb
updatedb: can not find group `mlocate'

when i run updatedb

linfan

But if i do nano -w /etc/group and change locate:x:21: to mlocate:x:21: then it works. Is that ok?

linfan

mlocate-0.16-2.pkg.tar.gz is broken. It is using the old mlocate.install, can somebody rebuild this package and make sure it uses the upto date PKGBUILD and mlocate.install from CVS. Thanks.

Also the package should NOT contain var/lib/mlocate/mlocate.db, I'm not sure how this got in it's not created by the PKGBUILD anymore. The database is created the first time the user runs updatedb, updatedb will make sure it has the correct owners/permissions.

Attached is a patch for mlocate.install to fix any broken permissions caused by previous upgrades.

there is something missing in the extra mlocate 0.16-2 package - the file system/mlocate/mlocate.db is empty.

linfan

you need to run 'updatedb' as root.

as i already told you i get the above errors.

But I tried to download the files from the home page and there is a file called mlocate.db - but it doesn't contain anything it is blank and I cannot nano -w a file that is empty, can I? Maybe I should to nano -w mlaocate.db and type only a hash (#) and then save it.

I am confused,

linfan

Ok, i patched it but had manually to rm -rf /var/lib/mlocate* and NB! mlocate:x:21: was added to /etc/group, not simply locate:x:21:


linfan

The mlocate package is borked.
I just installed the update, and it removed my old mlocate group, and put in the locate group.
mlocate appears to still want the mlocate group, however...as Börje already noted. I created the group manually (which the update had removed *sigh*) and it ran fine.

Was this package update tested at all before being pushed to extra?
I would think a cursory install and attempt to run the binary would have shown the problem...

The package in the repository is broken. The changes do work and have been tested, but the PKGBUILD and mlocate.install bein used to create the package don't match whats in CVS.

I've built it myself and uploaded a working and tested version to http://linux.neptune-one.net/mlocate/mlocate-0.16-3-i686.pkg.tar.gz

You can find the working PKGBUILD and mlocate.install there as well.

ty, Andrew :)

Your package works fine.

The extra package just sucks - something is still wrong with that one in there.

linfan

Andrew's package works fine for me too.

Thanks.

darn, i coulda sworn i commented here... im having no luck whatsoever with this package :/

so, i put -3 in the repos yesterday, does it work for you? Does for me.

James

Ok, James, worked here now on all my three computers - p2, p4 and 32 bits amd64.

Thanks :)
