Screenshots don't show up

[Scott Grayban]

Maybe I'm just stupid but I don't know where these screenshots are suppose to be viewed at.

I click on the nav menu for it and I only get the description for it and the source says no image.

<div id="content" class="screenshots">
  <div class="title">
    <h1>Screenshots</h1>
  </div>

  <div class="header">
    <b>Component:</b> core (Non gui core bugs.) <b>Version:</b> 1.0 
  </div>

  <div class="images">
    <div class="previous">
      
        
          <a class="noimage" href="#"></a>
        
      
        
          <a class="noimage" href="#"></a>
        
      
    </div>

Nevermind -- I still had that broken HackInstallPlugin still.

But still have issues with seeing the screenshots still.

Is path = <path_to_screenshots> full path or relative to the project? EG; site/screenshots/

Because the link to the screen shot is giving me ​http://dev-1.borgforge.net/castpodder/screenshots/castpodder_screenshot_large.png when it should be ​http://dev-1.borgforge.net/castpodder/chrome/site/screenshots/castpodder_screenshot_large.png

Hello,

path variable is absolute so you should set it as ie. /var/lib/trac/project_1/screenshots . If you set path as this example and your problems will be otlasting, please remove HackInstallPlugin or solve problems with it and post me log output here. Note that ImageMagick tools properly installed is needed for running this plugin.

Still not working and I removed the hackinstall already.

I think you need to set the path relative to the project. EG; site/screenshots where site would always be /var/trac/project/htdocs

Because the htdocs is the public web folder and anything outside of that will not work as a link.

[Scott Grayban]

whoops sorry -- I forgot to login.

This is what I have in my trac.ini

[screenshots]
path = /var/trac/project/castpodder/htdocs/screenshots
title = Screenshots

The link for the image is wrong no matter what I set it to.

You use a static link which is bad => ​http://dev-1.borgforge.net/castpodder/screenshots/castpodder_screenshot_large.png

When it SHOULD use => ​http://dev-1.borgforge.net/castpodder/chrome/site/screenshots/castpodder_screenshot_large.png

See the problem?

Your path is for saving the screenshots and not for the links/thumbs.

[Radek Bartoň]

With URL ​http://dev-1.borgforge.net/castpodder/screenshots/castpodder_screenshot_large.png is nothing wrong. This URL is inside the plugin interpreted to filename and then appended to the end of path config variable and returned to the request object. So there is problem with this appending and returning. The reason why URL ​http://dev-1.borgforge.net/castpodder/chrome/site/screenshots/castpodder_screenshot_large.png is working is coincidence that you have stored you screenshots inside htdocs dir, but image is returned to the request by core trac modules. Of course you have to set you path variable to directory which is to the web server accesible (ie. has apache ownwer), but it can be everywhere on the system. I'll take a close look on the code to consider what could be wrong but debug log output should tell me more. Unfortunately I'm afraid that there is no enough relevant debug prints in the code so I'll make a new changeset which you could try evoke error with.

[Scott Grayban]

Your thinking apache -- you can't -- I and alot of others use the standalone server. It's faster then apache.

You need to make sure the thumbs and link for the pictures are set to use the template paths here.

Standalone server can't use rewrite rules.

The graphviz plugin is a good example to follow. He uses template paths to render and show the graphic. And a separate path for the URL.

[graphviz]
cache_dir = /usr/share/trac/htdocs/graphviz
prefix_url = http://dev-1.borgforge.net/castpodder/chrome/common/graphviz

[Radek Bartoň]

By standalone server you mean tracd? Because I'm testing with tracd and there is no problem with it. I tried plugin with apache now and there problem is. Image is returned by req.send_file(path, type) so it should work everywhere.

[Radek Bartoň]

I've commited new changeset 1078 which fix mistake in mime type returning. It should help so please try it.

[Scott Grayban]

It works now :)

Now all you need to do is add config options to set the default component and version to use.

[Scott Grayban]

Oh and maybe a modify feature as well.

I do like this plugin since I can make screen shots depending on the version if any changes where changed.

Another cool feature would be the use of the tags plugin so you can also tag the screenshots.

But I will close this ticket and post a new one for the features.

[Radek Bartoň]

I was considering make option to assing one screenhsot to more component or versions too.
