Feedchecker Version 0.4

Änderungen

Nach Feedback auf den letzten Blogeintrag habe ich mich nochmal an das Feedchecker Script gemacht und ein paar Änderungen eingepflegt:

  • Ruby 1.8 Kompatibilität (da ich selbst auf Ruby 1.9 entwickle)
  • Vereinfachtes Suchen der Urls durch XPath-Expression
  • Konfigurierbare Anzahl der parallel abzuholenden Feeds

./feedchecker.rb -h
This is a simple, script which takes an opml file and checks all contained feeds for
errors.

 Usage:

feedchecker.rb [options] -i <filename>

where [options] are:
          --input, -i <s>:   Input opml file
        --timeout, -t <i>:   Timeout interval in seconds (default: 60)
            --age, -a <i>:   Specify the minimum age in days (default: 365)
  --fetchparallel, -f <i>:   Specify the amount of feeds to fetch parallel (default: 5)
            --version, -v:   Print version and exit
               --help, -h:   Show this message
 

Mehr Details gibts in der Commit-History auf github.

Geschwindigkeit

In meinen Tests verwende ich meine Liste mit ca. 160 Feeds. Einmal mit den Standardeinstellungen und einmal mit der Option, dass 10 Feeds parallel abgeholt werden.

Zuerst ein paar Vorbereitungen:


wget http://github.com/pfleidi/feedchecker/raw/master/feedchecker.rb
chmod +x feedchecker.rb
 

Mit Standardeinstellungen:


time ./feedchecker.rb -i feeds.opml
...
real    1m33.162s
user    0m18.909s
sys     0m1.296s
 

Mit 10 Threads:


time ./feedchecker.rb -i feeds.opml -f 10
...
real    1m20.754s
user    0m19.493s
sys     0m1.340s
 

Mit 10 Threads und aggressiveren Timeouts von 20 statt 60 Sekunden:


time ./feedchecker.rb -i feeds.opml -f 10 -t 20
...
real    0m39.808s
user    0m19.205s
sys     0m1.472s
 

Viel Spaß damit und ein frohes Fest euch allen!
