Description

rudder 3.0.2

If I run manually "cf-agent -KI" on the policy server, it is apparently stuck right after:

2015-03-26T09:25:55+0100     info: /default/root_component_check/methods/'any'/default/compress_webapp_log/files/'/var/log/rudder/webapp'[0]: Transforming '/bin/gzip "/var/log/rudder/webapp/2015_03_13.stderrout.log"'

After some time I got bored and pressed Enter, and I could see the following log line:

2015-03-26T09:26:02+0100     info: /default/root_component_check/methods/'any'/default/compress_webapp_log/files/'/var/log/rudder/webapp'[0]: gzip: /var/log/rudder/webapp/2015_03_13.stderrout.log.gz already exists; do you wish to overwrite (y or n)?       not overwritten
2015-03-26T09:26:02+0100    error: /default/root_component_check/methods/'any'/default/compress_webapp_log/files/'/var/log/rudder/webapp'[0]: Finished command related to promiser '/var/log/rudder/webapp' -- an error occurred, returned 2
2015-03-26T09:26:02+0100    error: /default/root_component_check/methods/'any'/default/compress_webapp_log/files/'/var/log/rudder/webapp'[0]: Transformer '/var/log/rudder/webapp/2015_03_13.stderrout.log' => '/bin/gzip "/var/log/rudder/webapp/2015_03_13.stderrout.log"' returned error

Then it's stuck the same way for 2015_03_16.stderrout.log…

I guess you should do what's necessary to ensure the commands called are not in interactive mode. ;-)

Thanks.

Hello,

Thanks for the report. As far as I understand, there is two problems here:

- of course gzip should not be used in interactive mode ever !
- we have already an archive for the 2015_03_13 logs. This should not happen.

For the second part, I can see two causes, and 4 choices about what to do. Let's start with the choices:

if both xxx and xxx.gz exists:

- 1/ do nothing
- 2/ keep the gz and delete the xxx
- 3/ delete the gz and gzip the xxx (or overwrite the existing gz)
- 4/ create a xxx.1.gz (or any other unique id that it is an other archive for the log - maybe a timestamp, so that it is really unique without dealing with incrementing things)

So for the possible cause to have both files present:

- 1/ some user uncompressed the archive not in place (to keep both, for example with gunzip c or gzcat)
 2/ somehow, the application created some more entries in the xxx file (rotated to early ? badly closed file descriptor ? )

The cause 2 is the one we want to manage correctly, because it means that loosing any file loose information. By consequence, choice 2 and 3 are not possible. I don't know what is the best one, thought.

Moreover, perhaps we should treat the two problems in two bugs. But they seem rather hard linked one to each other.
Benoit, any thought ?

I got stuck as well, on a freshly installed server. Don't know why it compressed immediately the log thought

  • Found in version(s) old 3.0.3 added

We think the problem is:
- We use the range between 2 days ago and now to detect is a file should not be compressed
- If the current log file is written during execution, its change time will be after the "now" of cfengine
- The techniques then decides to compress current log whereas it shouldn't
