CATS Proxy Authentication?

Is the problem still existing?

Think so, at least I didn't touch it =)

Just tried again. Downloaded the same version of cats, and now get a version error for both renderfarm.fi and burp.renderfarming.net

"Could not attach to http://www.renderfarm.fi not a BURP-based project or not using the correct version of CATS"

Couldn't get any further.

I've been hacking at CATS all day and think I figured out the proxy issue (this was my first look at java code).

I managed to track it down to the getBaseURL() function in /src/cats/domain/Project.java The connection instruction doesn't check the proxy settings. I changed this...

<code>
     HttpURLConnection conn = (HttpURLConnection) ((new URL(url)).openConnection());
</code>

...to this...

<code>
     URL correctURL = null;
     URL proxyURL = Core.getProxyURL();
     if (proxyURL == null){
       correctURL = new URL(url);
     }else{
       correctURL = new URL("http",proxyURL.getHost(),proxyURL.getPort(),url);
     }

     HttpURLConnection conn = (HttpURLConnection)correctURL.openConnection();
</code>

It now appears to be attaching under a proxy (when configured). But now fails to get files in the DownloaderThread :( So I put similar code in the loadFiles() function of /src/cats/domain/Frame.java

Added...

<code>
     URL correctURL = null;
     URL proxyURL = Core.getProxyURL();
     if (proxyURL == null){
       correctURL = new URL((String)fileMap.get("url"));
     }else{
       correctURL = new URL("http",proxyURL.getHost(),proxyURL.getPort(),(String)fileMap.get("url"));
     }
</code>

...and replaced <code>new URL((String)fileMap.get("url"))</code> with <code>correctURL</code> in the imageFiles.put() function

There's still the issue of a new user without a cats.cfg file. They can't attach the first time if they're behind a proxy because there's no option in the GUI to setup the proxy (until after they connect). But I'll leave that to the experts.

Of course it's not "live" until one of you admins makes the changes to the real code (and verifies my work!). Hopefully my hacks didn't break anything else. :)

Thanks alot for the code suggestion Overkill. I promise we'll take a look at it during next week :).

Thanks for following up on CATS. I hope it helps.

I was just using CATS to download my frames (session 469) and realized the filenames are padded with 3 zeros (%03d) but my session has over 1000 frames. So frame "999.png" doesn't sort nicely with frame "1000.png".  :(

Looked at the code and noticed a (hidden?) format "%f4id" for 4 zeros (%04d) in DownloaderThread.java. Can this be the new default when configuring the filename syntax?

Thanks.

If you can verify that Blender loads in these files without any issues then sure it can.

I wouldn't think Blender cares either way. It's just the local filename and shouldn't affect burp or blender at all. I did a few tests with blender (2.52) and it appears they use %04d for the .png files it creates (while rendering animations).

Ideally CATS could do some fancy determination based on the last frame rendered (i.e. if the last frame is "100", use %03d, if frame "1000" use %04d, if frame "10000" use %05d, etc.). This is probably "overkill" :) , but I modified more code to make the zero prefix length automatic...

.
Updated the Locales files and StartDownloadFrame.* files to make "%f0id" the defailt for "Zero prefixed frame number" (search/replaced "%f3id" with "%f0id"). Then examined the length of getEndFrame() to determine the correct padding...

In DownloaderThread.java I removed the %03d and %04d lines...

<code>
     filename = filename.replace("%f3id", String.format("%03d", frm.getFrameNumber()));
     filename = filename.replace("%f4id", String.format("%04d", frm.getFrameNumber()));
</code>

And added the following to automatically adjust the prefix ("%f0id").

<code>
     String endFrame = ""+downloadSpec.getEndFrame();
     String autofmt = "%0"+endFrame.length()+"d";
     filename = filename.replace("%f0id", String.format(autofmt, frm.getFrameNumber()));
</code>

Tested on session 1031 (1-1 frames). It formatted with "%01d" (1.png)
Tested session 271 (1-25 frames). It formatted with "%02d" (01.png-25.png)
Tested session 526 (1-200 frames). It formatted with "%03d" (001.png-200.png)
And tested session 932 (810-1830 frames) It formatted with "%04d" (0810.png-1830.png)

Hope it makes the next version.

I downloaded CATS and wanted to bump this thread again to see if anyone (devs) has had a chance to look at it. I'm using my "overkill version" with these changes, and it seems to be working well (proxy authentication & zero prefixed filenames).

File naming changed 3 days ago. I'll recompile a new CATS for us.
