Bugs item #3464439, was opened at 2011-12-23 08:15 Message generated for change (Comment added) made by fabiankeil You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=111118&aid=3464439&group_id=11118 Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: None Group: None Status: Pending Resolution: None Priority: 5 Private: No Submitted By: Kevin (photo2110) Assigned to: Fabian Keil (fabiankeil) Summary: Page truncation Initial Comment: When working with Opera 11.60 and Privoxy, pages, images, etc will randomly get truncated. It just started with the Opera upgrade, so it might be a bug with Opera, but when I stopped using Privoxy, I couldn't get any pages to fail. Note: 'stopped using' means configuring Opera to not go through Privoxy, simply unchecking 'Enable' on the Privoxy menu doesn't do it. I attempted to capture data with Wireshark, but the pages I caught were gzipped and I can't be certain that they were good. I did notice that they were http 1.1, if that makes a difference. Only one other person has mentioned on the Opera news group that they are having an issue like this. They too are running Privoxy. NYTimes.com seems especially bad to me, but it happens on all sites including SouceForge. Privoxy 3.0.18. Opera 11.60 Windows 7 and Windows XP (I have two machines, both have the trouble) No other proxy software. Windows Firewall and MSE on both machines.

I tried reproducing it by sending the same headers Opera used, but the response appears to be complete. Unfortunately Privoxy's log buffer is smaller than the receive buffer so full receive buffers aren't logged completely in which case the received data can't be reconstructed. Can you still reproduce the problem if you enable +prevent-compression? A log file without compressed content would probably be easier to analyze. ---------------------------------------------------------------------- Comment By: qqqqqw (qqqqqw) Date: 2012-01-17 11:31 Message: I never use turbo mode ---------------------------------------------------------------------- Comment By: Lee (ler762) Date: 2012-01-15 12:59 Message: Try disabling turbo mode in Opera. I installed Opera and, with extremely limited testing, it worked fine until I enabled "turbo mode". At which point it broke. Changing the privoxy config to keep-alive-timeout 0 helped some, but did NOT fix all of the problems. I had wireshark capturing traffic during my testing. I thought I'd figured out the problem but now I'm not so sure :( I need to look at the packet traces again.

I have never page truncation on https 2. If i have page truncation on a site and the i use a cgi proxy to go to the same page i have no page truncation ---------------------------------------------------------------------- Comment By: Fabian Keil (fabiankeil) Date: 2012-01-13 14:23 Message: Downloading the file from zshare.net doesn't work for me. The download server doesn't even bother to return HTTP headers. In theory you should be able to upload a file through the "Add a file" section on this page. ---------------------------------------------------------------------- Comment By: qqqqqw (qqqqqw) Date: 2012-01-13 03:30 Message: Page truncation on mashable.com with Opera 11.60 + Privoxy 3.0.19 and socks4a + Tor Log file with this debug enabled: debug 1 debug 2 debug 4 debug 8 debug 64 debug 128 debug 256 debug 512 debug 1024 debug 4096 debug 8192 debug 32768 Log file is here: http://www.zshare.net/download/986014474c9073b3/ How can i attach log file in this discussion? ---------------------------------------------------------------------- Comment By: qqqqqw (qqqqqw) Date: 2012-01-01 10:09 Message: Yes, i use Opera 11.60 and the problem is always on same site (i dont know why) After the upgrade to 3.0.19 and a quick surf seem that the problem is socks5 + Tor (so Privoxy 3.0.18 for bug in socks4a) and NOT socks4a + Tor (so Privoxy 3.0.19) But i need more test (surf to more internet pages and try to use socks5 on Privoxy 3.0.19) If i have other page truncation i post a log ---------------------------------------------------------------------- Comment By: Fabian Keil (fabiankeil) Date: 2011-12-31 05:02 Message: qqqqqw, are you using Opera as well? Is the problem easy to reproduce? Can you provide a logfile with the usual debug directives and additionally "debug 16" and "debug 32768"? It would be especially useful to additionally get a pcap file that shows the packages Privoxy was receiving and sending. I think it's unlikely that upgrading to 3.0.19 makes a difference. You could try the recently uploaded privoxy-3.0.19-ipv4only.zip as it uses different code paths, but it probably will not make a difference either. ---------------------------------------------------------------------- Comment By: Kevin (photo2110) Date: 2011-12-29 11:58 Message: Sorry I've not replied sooner. Xmas break took priority. I put in a section to downgrade the NYTimes, and couldn't get any more issues with that site. So, I put in a downgrade for all of .com, and haven't seen anymore short pages on a .com site. I'll have to try the new .19 version. ---------------------------------------------------------------------- Comment By: qqqqqw (qqqqqw) Date: 2011-12-29 11:53 Message: I have the same problem. Initially i think that this problem is related with socks4a/5 bug, but after read this i'm not so sure. I have page truncation with Privoxy 3.0.18, not with 3.0.17. Now i try with 3.0.19 ---------------------------------------------------------------------- Comment By: Fabian Keil (fabiankeil) Date: 2011-12-23 11:21 Message: Thanks. I can't see any obvious problems in the log. Please additionally add "debug 16" so the data written to the network is included as well. Does it make a difference if you add the following to one of your action files?: {+downgrade-http-version} # Sticky Actions = +downgrade-http-version # URL = http://www.nytimes.com/pages/travel/index.html .nytimes.com/ ---------------------------------------------------------------------- Comment By: Kevin (photo2110) Date: 2011-12-23 10:06 Message: New log file added with debug 32768 turned on.

I'm apparently not understanding the log file, it looks like it grabbed the page twice, with the second grab bad. ---------------------------------------------------------------------- Comment By: Fabian Keil (fabiankeil) Date: 2011-12-23 08:36 Message: Thanks for the report. Please reproduce the problem after enabling logging as described at http://www.privoxy.org/user-manual/contact.html#CONTACT-BUGS and provide a log file. If you can make the pcap file created with Wireshark available, that may be useful, too. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=111118&aid=3464439&group_id=11118 |
