| Summary | 0004446: remote includes: rehash never finishes if DNS server is down | ||||
| Description | I killed my DNS today for testing (due to other issue). UnrealIRCd boots OK, after 15sec timeout, using cached version instead etc. etc. Then, when I /REHASH on IRC, it says: [11:32:10] -maintest.test.net- *** Syzop is rehashing server config file [11:32:10] /home/syzop/unrealircd/conf/unrealircd.conf Rehashing and that's it... it never finishes. I forgot about it and it was still like this 1 hour later. If you try to /REHASH again it says 'A rehash is already in progress', IOTW: the server is now un-rehashable. Not good. | ||||
| Additional Information | Latest UnrealIRCd build libcurl/7.45.0 OpenSSL/1.0.1k zlib/1.2.8 c-ares/1.10.0 libidn/1.29 libssh2/1.4.3 so compiled with c-ares etc. | ||||

Event is being called fine every second... (gdb) b curl_socket_timeout Breakpoint 1 at 0x47e77e: file url.c, line 345. (gdb) c Continuing. Breakpoint 1, curl_socket_timeout (data=0x0) at url.c:345 345 { (gdb) n 348 curl_multi_socket_action(multihandle, CURL_SOCKET_TIMEOUT, 0, &dummy); (gdb) 349 } (gdb) quit |

After 15 seconds url_socket_cb gets called to unmap/close the fd, but.. other than that nothing... no curl function is called to say that the downloading failed or has finished I've been breaking on: b url_socket_cb b url_check_multi_handles b download_file_async b conf_download_complete b remote_include |
