Serving content from a WARC
The proxy should remove unknown headers, such as X-Frame-Options SAMEORIGIN.
using the firefox extension, the filepicker doesn't allow me to select any .warc.gz
firefox 16.0.2 on osx
https://github.com/alard/warc-proxy/blob/master/firefox-addon/lib/main.js#L22
what is the right procedure to rebuild the xpi?
thank you
I tried to load a WARC with a few larger (200-300 MB) files in it. During the process of loading (indexing) the WARC, memory usage of the python process (that worked on the indexing) increased up to, like, 700 MB, and then ran out of memory, leaving the following error message in the terminal:
Loading /media/datadisk/upload_queue/hajduvolan_hu_2015_05.warc.gz

The progress bar stuck, the indexing stopped.
I bet on the big files being responsible for this, as I've been using this great tool for long and haven't experienced such a problem so far (this was the first time that I tried to load a WARC with files larger than a few tens of megabytes). However, I can't imagine why warc-proxy would need 700 MB of mermoy for indexing a 250 MB file.
I think you can easily reproduce the problem: you can find the problematic WARC here: https://archive.org/details/hajduvolan_hu_2015_05. The probably problematic files are http://www.hajduvolan.hu/files/userfiles/Flash/EU_projekt_2010-2012.flv (249 MB) and http://www.hajduvolan.hu/files/userfiles/Flash/EU_projekt.flv (146 MB).
Usually the bottle-neck is HDD/Flash speed, but in the case of the warc-proxy the command "top" shows on 4-core Raspberry Pi 3 that the "waiting" part is about a few %, while the python process that runs the warc-proxy consumes only slightly more than 1 CPU-core. The rest of the 2-point-something cores sit idle.
An initial workaround might be to read the number of cores from the
/proc/cpuinfo
and then start that many very-low-level threads, one thread per importable WARC-file. A more proper solution is to try to prepare for utilizing hundreds of CPU-cores (archival copy).
I installed the addon to Firefox 24.0 on Ubuntu Linux but it does not appear in the Tools menu. It does appear in the Addons list. Suggestions?

The ~560MiB sized WARC-file that probably was used, when this happened, MIGHT be available from
http://temporary.softf1.com/2017/bugs/www.clausewitz.com-2017-02-09-8df72096-00000.warc.gz
It might have happened with some other WARC-file, I'm not totally sure, but the referenced one also fails to load for what ever reason.
HTTPS traffic is not going to the WARC proxy. The proxy settings should be changed to do that. The proxy code should be changed to be able to serve the HTTPS records.
In stead of scanning the disk for file system changes at the moment, when the file selection dialog is opened, the disk is scanned for file system changes only when the web application page at the web-browser is reloaded (by pushing the F5 button).
The result is that new WARC-files that are created after the web application has been launched, are not visible at the file selection dialog. People, who are new to the application do not necessarily expect that they have to refresh the whole web page to see the updates.
Hello! I'm a new one in these Python and Warc themes, so please be gentle.
Well, I've performed some actions, as seted out in steps 1-5: installed Python 3.6.2, tornado 4.5.2, ran the proxy and setted my browser to required parameters regarding proxy.
And what is next? How should I use this viewer? Can anyone explain me in more details?
Thank you.
