Created attachment 6066 [details] polipo-log.1395243368.31949_android-backup-post polipo-1.0.4-alt1.1.qa1 My polipo is configured to listen on port 8117 and to forward connections through TOR. I've discovered that on some requests from Android, it crashes. Here is a report, and the request is attached (polipo-log.1395243368.31949_android-backup-post): [imz@localhost after-core-2]$ /sbin/service polipo status polipo is running [imz@localhost after-core-2]$ netcat 0 8117 < polipo-log.1395243368.31949_android-backup-post HTTP/1.1 405 Method not allowed Connection: keep-alive Date: Thu, 20 Mar 2014 15:14:04 GMT Content-Type: text/html Content-Length: 440 Expires: 0 Cache-Control: no-cache Pragma: no-cache <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html><head> <title>Proxy error: 405 Method not allowed.</title> </head><body> <h1>405 Method not allowed</h1> <p>The following error occurred while trying to access <strong>/backup</strong>:<br><br> <strong>405 Method not allowed</strong></p> <hr>Generated Thu, 20 Mar 2014 19:14:04 MSK by Polipo on <em>vaio:8117</em>. </body></html> HTTP/1.1 405 Method not allowed Connection: keep-alive Date: Thu, 20 Mar 2014 15:14:04 GMT Content-Type: text/html Content-Length: 440 Expires: 0 Cache-Control: no-cache Pragma: no-cache <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html><head> <title>Proxy error: 405 Method not allowed.</title> </head><body> <h1>405 Method not allowed</h1> <p>The following error occurred while trying to access <strong>/backup</strong>:<br><br> <strong>405 Method not allowed</strong></p> <hr>Generated Thu, 20 Mar 2014 19:14:04 MSK by Polipo on <em>vaio:8117</em>. </body></html> [imz@localhost after-core-2]$ /sbin/service polipo status polipo is dead, but stale PID file exists [imz@localhost after-core-2]$ The request is a kind of a POST request (since it's binary and not plain text, you'd better take it from the attachement): [imz@localhost after-core-2]$ cat polipo-log.1395243368.31949_android-backup-post POST /backup HTTP/1.1 Content-Length: 942 Host: android.clients.google.com Connection: Keep-Alive User-Agent: Android-Backup/1.0 (GT-P7500 HMJ37) Íùƚö3com.android.providers.settings2Ù ￭CONFIG_WIFIÆ proxySettingsNONEid<UͯeostDHCP ipAssignmentSTATIC proxySettingsNONEid²·eos254.178.30dns169.254.178.30ss proxySettingsNONEidíÛeosipAssignmentDHCP proxySettingsNONEidùleosipAssignmentDHCP proxySettingsNONEidVk1neosAssignmentDHCP proxySettingsNONEid°]zfeosipAssignmentDHCP proxySettingsSTATIC proxyHostnmentDHCP exclusionLisgrani.ruidÆÔpeos 192.168.1.2 proxyPort¶ proxySettingsNONEidmeosr DQAAAMoAAADhMjZo4Hm2tf0w2NgZod1o1Rt4QIOJb5u6ThuQLfV58uZox5-UclYXvwOLiLfRLh73XoxfW4n-fEegFKwaKG5i9Bha0Un65H47NVK4iyDNp9DLsp-DGM-pDvnr11ua_xjkDh80rHR84fiIjoiIktN_ItFYAWjqog-Vdy6N6dREc2W-JPNBbigyPGlxDo0xzpnwZvqKDM24eheEHp1Xo1ACbN9SJPcCGCYMebmUvaN8wJOAsipbA6kx192QedhLBquZJt8p8El9w94UQm4GItcx[imz@localhost after-core-2]$ A backtrace: [imz@localhost after-core-2]$ gdb -c core.polipo.30971 -e /usr/bin/polipo GNU gdb (GDB) 7.5.0.20121002-alt3 (ALT Linux) Copyright (C) 2012 Free Software Foundation, Inc.

(gdb) There seems to be nothing more intersting in the logs, even after raising polipo's log level to 0xFF.
According to the mailing list http://sourceforge.net/p/polipo/mailman/polipo-users/?style=threaded&limit=250, there is a newer version of polipo in the HEAD of their VCS. It should be tested. They haven't yet made a newer release though.
I was able to find out the "bad" request and to write this report, after I learned how to turn on core dumps in my system (http://www.altlinux.org/Features/Core ), and invented a way to intercept and log the requests going to polipo (with a combination of xinetd, tee, and netcat; simply using netcat, and tee, and netcat was not that good because it failed to listen to "parallel" incoming connections).

В сизифе уже версия 1.1.1. Проблема ещё актуальна?
Раз молчание, значит, уже неактуально.
