Description jospezial 2014-11-20 21:12:55 UTC
with dev-util/ccache-3.2 installed I get:

ccache: error: /var/tmp/ccache//ccache.conf: Permission denied

-rw------- 1 root portage 14 20. Nov 21:53 /var/tmp/ccache/ccache.conf

chmod -v g+rw /var/tmp/ccache/ccache.conf does not help. Something does set the wrong permissions back.

odd, it keeps getting set to -rw-r--r-- on my system.  what are the perms of the other files in that dir ?

No other files here, because it apparently errors out before it can create any:

   $ ls -la /var/cache/ccache/
   total 12
   drwxrwsr-x  2 root portage 4096 Nov 21 09:07 .

   -rw-------  1 root portage   14 Nov 21 09:07 ccache.conf

This is with:

Comment 5 SpanKY gentoo-dev 2014-11-21 08:19:20 UTC
(In reply to Ulrich Müller from comment #4)

if you clear the dir and build, does it die before it gets a chance to build ?  i cleared the whole thing and rebuilt ccache a few times ... using userfetch userpriv usersandbox as well.

i'm not seeing ccache doing any permission modifications itself.  it just creates the file if it didn't already exist.  it uses O_CREAT/0666 as to be expected.

i know portage does some permission adjustment on the ccache dir ...

using it by hand outside of the sandbox look weird too ?

Comment 9 Viktor Yu. Kovalskii 2014-11-22 08:53:32 UTC
Permissions are changed after setting cache size by ccache -M:

# ls -l ~/.ccache/ccache.conf
-rw-r--r-- 1 root portage 16 Nov 22 14:49 /root/.ccache/ccache.conf

# ccache -M 10G
Set cache size limit to 10.0 GB

# ls -l ~/.ccache/ccache.conf
-rw------- 1 root portage 15 Nov 22 14:50 /root/.ccache/ccache.conf
Comment 10 jospezial 2014-11-22 14:08:41 UTC
Could this be set wrong by default?:

umask (CCACHE_UMASK)

This setting specifies the umask for ccache and all child processes (such as the compiler). This is mostly useful when you wish to share your cache with other users. Note that this also affects the file permissions set on the object files created from your compilations.

Does this affact the config file?
Comment 11 Nick Herman 2014-11-22 14:22:19 UTC
This is the ccache code change that makes 'ccache -M' always update ccache.conf mode to 0600 in ccache v3.2 (as create_tmp_file() creates files with 0600 in mode bits):

https://git.samba.org/?p=ccache.git;a=blobdiff;f=conf.c;h=92c70c0648d5f5339fc28c889107f32f61c4bbb9;hp=56adb484ecd4079906e50aef03f930c5d98f7b79;hb=fc61ca9a9232f26ee3f714d4b8738d916f6948ff;hpb=f49770a4b142e82a3cf1f5e1da158f69e0447972
Comment 12 jospezial 2014-11-22 15:15:37 UTC
very inconsistent behaviour:
ccache -M 10G and ccache -s produce the new configfile with different permissions.

bastellinux ~ # rm -r /var/tmp/ccache
bastellinux ~ # ccache -M 10G
Set cache size limit to 10.0 GB
bastellinux ~ # ls -la /var/tmp/ccache/

Also you see no portage group used.

@ Nick Herman:
Did you try to reverse the commit?
Comment 13 Nick Herman 2014-11-22 15:41:33 UTC
@jospezial

I tried reversing just those two lines in diff and ccahce.conf seems to always have 644 mode after applying ccache -M now.

$ CCACHE_DIR=/tmp/.ccache ./ccache -M 3G
Set cache size limit to 3.0 GB
$ ll /tmp/.ccache/
total 4.0K
-rw-r--r-- 1 gen gen 14 Nov 22 18:39 ccache.conf
$ chmod 0600 /tmp/.ccache/ccache.conf
$ ll /tmp/.ccache/
total 4.0K
-rw------- 1 gen gen 14 Nov 22 18:40 ccache.conf
$ CCACHE_DIR=/tmp/.ccache ./ccache -M 2G
Set cache size limit to 2.0 GB
$ ll /tmp/.ccache/
total 4.0K

@vapier: How about package.masking ccache-3.2 until this issue is resolved?
Comment 15 Justin Lecher (RETIRED) gentoo-dev 2014-11-23 09:45:03 UTC
As a workaround, I dropped the CCACHE_SIZE from make.conf (The default changed from 1-5 GB) and deleted the ccache.conf.
Comment 16 jospezial 2014-11-23 22:22:30 UTC
something more to the inconsistency of the permissions:

I deleted /var/tmp/ccache/ , removed the ccache size and path settings from /etc/make.conf and deleted the file in /etc/env.d . (don't forget to do env-update and reboot or do source /etc/profile)

After the reboot I emerged updates (worked without problems).
And this is the ccache.conf that emerge creates:

ls -la /var/tmp/ccache/

Here we have write permission for the group too.

For next I will try to set the path in the new /etc/ccache.conf (does not yet exist on my system).
If you set nowhere CCACHE_DIR then emerge uses /var/tmp/ccache/ .
But then ccache -s creates and uses ~/.ccache/ for the user.
Comment 17 jospezial 2014-11-24 01:16:51 UTC
If you want to set the path in /etc/ccache.conf for systemwide you need the to write it in lower letters as you can see in manpage because it is not an environment variable.
Note the little difference (not ccache_dir):

cache_dir=/var/tmp/ccache

Don't use " and no / on the end of line.

The funny thing is the output of ccache -s as normal user. It shows all counters zero even if the user is in the portage group.

joerg@bastellinux ~ $ ccache -s
cache directory                     /var/tmp/ccache
primary config                      /var/tmp/ccache/ccache.conf
secondary config      (readonly)    /etc/ccache.conf
cache hit (direct)                     0
cache hit (preprocessed)               0
cache miss                             0
files in cache                         0
cache size                           0.0 kB
max cache size                       5.0 GB

That's because the the stats files are not readable by group (portage).

With this being pretty clearly an upstream bug I filed it as such.  Could someone (the author?) with the privs put this link in the URL field?

https://bugzilla.samba.org/show_bug.cgi?id=10978

(For now I'm simply masking 3.2.  If 3.1.10-r1 was working before, it should continue working a bit longer.  I have a new printer and need to rebuild some stuff with USE=cups.)

Comment 20 Weedy 2014-12-08 19:34:25 UTC
Going forward can we make sure things like the new config file, stats files, whatever CACHEDIR.TAG is all get 664? Not to mention the cached files themselves are sometimes 600 for lord knows what reasons.

I use all the user* FEATURES and it's playing havoc with calling ccache -s
Comment 21 Marc Schiffbauer gentoo-dev 2014-12-11 22:04:41 UTC
3.2.1 has been released, which seems to fix that issue:

https://ccache.samba.org/releasenotes.html#_new_features_and_improvements

"Fixed regression in temporary file handling, which lead to incorrect permissions for stats, manifest and ccache.conf files in the cache. "

Please bump ;)
