Error in rsync protocol data stream

Posted on by

So I was running a backup with rsync and I saw this:

lib/mysql/ibdata1
        437.40M  33%    4.53MB/s    0:03:10  
inflate returned -3 (0 bytes)
rsync error: error in rsync protocol data stream (code 12) at token.c(557) [receiver=3.1.2]
rsync: connection unexpectedly closed (155602 bytes received so far) [generator]
rsync error: error in rsync protocol data stream (code 12) at io.c(235) [generator=3.1.2]

The issue seems to be that if you're using rsync compression and the remote file gets changed while the rsync copy is in progress then shit gets corrupted. My solution was to handle error level '12' and retry without compression. If the file changes while the rsync is in progress the file will be corrupt, so you shouldn't rely on the integrity of such files.

I was getting an error like this:

/etc/cron.daily/etckeeper:

etckeeper warning: bzr add failed
Committing to: /etc/
modified apache2/passwd.htdigest

Committed revision 87.

I've tried to fix it by adding:

export LANG=en_AU.UTF-8
export LANGUAGE=en_AU:en

As lines 2 and 3 in /etc/cron.daily/etckeeper.

Now I'll wait a day or two and see if it worked...

gnutls_handshake failed using git

Posted on by

Today I ran into this error:

jj5@mercy:~/public-git$ git push origin master
error: gnutls_handshake() failed: A TLS warning alert has been received. while accessing https://demo@demo.personalserver.com/public/git/info/refs

The solution, of all things, was to add a ServerName spec into my Apache configuration file /etc/apache2/sites-enabled/default-ssl.conf, e.g.:

ServerName demo.personalserver.com

Bug fixed!!

UnsupportedClassVersionError in Closure

Today while Getting Started with the Closure Compiler Application I ran into the following trouble:

jj5@mercy:~/Desktop/compiler-latest$ java -jar compiler.jar --help

Exception in thread "main" java.lang.UnsupportedClassVersionError: com/google/javascript/jscomp/CommandLineRunner : Unsupported major.minor version 51.0

To fix the problem I installed jdk-7:

Fixing mailman can’t discard/defer message via web config

Posted on by

I had a notice from Mailman for one of my lists that there was a message that required administrative attention (i.e. it was spam). The mailman web-interface provides a facility for treating email, however when I went to discard the message it wouldn't go away. I tried a heap of things and it took a long time to figure out, but eventually I noticed that in the mailman web page the domain name it was using was "intranet.blackbrick.com" whereas that should have been "www.intranet.blackbrick.com". So I did a little searching about how to configure a list's base URL and discovered this, which fixed my issue:

/usr/lib/mailman/bin/withlist -l -r fix_url support \
  --urlhost=www.intranet.blackbrick.com

Where 'support' above is 'list name'.

Error: post-commit hook failed (exit code 255) with no output

In subversion I was getting the error "post-commit hook failed (exit code 255) with no output" after trying to configure my post-commit hook to send email notifications. At first I thought the problem must have been related to the mailer, but I ran the mail command manually and it worked fine. Eventually I figured out that the problem was that the hooks/post-commit file hadn't been marked executable. So it was a simple chmod +x to fix the problem.
