Question

I just downloaded TWiki-4.0.4.tgz and hotfix-4.0.4-1.tgz from twiki.org, and it seems to me that the tar archives are gzipped twice. Is this correct or did I download some bogus version ?

Also, is there some checksum available to see if the downloaded archives are genuine ?

Environment

TWiki version: TWikiRelease04x00x04
TWiki plugins: DefaultPlugin, EmptyPlugin, InterwikiPlugin
Server OS:  
Web server:  
Perl version:  
Client OS:  
Web Browser:  
Categories: Installation, Security

ALERT! If you answer a question - or someone answered one of your questions - please remember to edit the page and set the status to answered. The status selector is below the edit box.

You probably downloaded with Internet Explorer. It has an idea that it should rename .tgz files to .gz. And sometimes even .zip to .tgz. It has something to do with interactions between Apache, mime-types and the browsers. Something we do not quite understand. But it happens also if I put a .tgz file in a plain directory on my Apache server.

If someone knows how to setup Apache to force IE to just plain download the file without any renaming then we would like to know.

The workaround for people with the problem is simple.

  • Either download with Firefox
  • Or rename the file to blabla.tgz after the file is downloaded.

The files that are uploaded are correct.

I just made a change to the apache configuration to not compress archive files when delivered by the viewfile script.

Could anyone please check if this fixes the issue, assuming identical environment as before when the problem occured?

It now works for TWiki-4.0.4.tgz, but the problem still remains for some plugins (e.g. DirectGraphPlugin, CompareRevisionsAddOn, FindElsewherePlugin, HistoryPlugin, RevCommentPlugin) which I all downloaded last week. (And I do use firefox, also during my first try to download TWiki)

Please try again. The reason for the difference is probably that the TWiki-4.0.4.tgz is downloaded using a direct URL to the pub directory. The plugins you download from the attachment table below the topic which means that you download using the viewfile script. Some changes were done to the Apache setup with respect to deflating with viewfile. It solved the problem in Firefox and in IE with zip files. tgz files are still renamed to .gz by IE.

Please reopen this if it is still an issue.
