| 0 | I am having trouble running github-backup under tor. A normal run works like this: | |
| 1 | ||
| 2 | $ github-backup --no-forks anarcat | |
| 3 | New repository: alabaster | |
| 4 | Clonage dans 'alabaster'... | |
| 5 | remote: Enumerating objects: 13, done. | |
| 6 | remote: Counting objects: 100% (13/13), done. | |
| 7 | remote: Compressing objects: 100% (11/11), done. | |
| 8 | remote: Total 1572 (delta 2), reused 11 (delta 2), pack-reused 1559 | |
| 9 | Réception d'objets: 100% (1572/1572), 508.50 KiB | 2.12 MiB/s, fait. | |
| 10 | Résolution des deltas: 100% (929/929), fait. | |
| 11 | [...] | |
| 12 | ||
| 13 | But running under tor (with [torsocks](https://github.com/dgoulet/torsocks)) hangs forever: | |
| 14 | ||
| 15 | $ torsocks github-backup --no-forks anarcat | |
| 16 | [blank, hangs forever] | |
| 17 | ||
| 18 | `strace` shows the process is looping over this: | |
| 19 | ||
| 20 | recvfrom(3, "", 2, 0, NULL, NULL) = 0 | |
| 21 | select(4, [3], NULL, NULL, NULL) = 1 (in [3]) | |
| 22 | ||
| 23 | file descriptor `3` is this, according to lsof: | |
| 24 | ||
| 25 | github-ba 18134 anarcat 3u IPv4 162905 0t0 TCP localhost:35828->localhost:9050 (CLOSE_WAIT) | |
| 26 | ||
| 27 | ... that's the local SOCKS connexion over to the tor daemon that | |
| 28 | `torsocks` reroutes the traffic to, with `LD_PRELOAD`, which I suspect | |
| 29 | is playing badly with the Haskell stack behind `github-backup`. | |
| 30 | ||
| 31 | So I understand this might be a compatibility issue - maybe the best | |
| 32 | would be to add SOCKS proxy support to github-backup? Not sure how | |
| 33 | best to solve this... --[[anarcat]] |
