Package: vdirsyncer Version: 0.16.7-2 Severity: normal Hi, it is very nice that Debian packages vdirsyncer and thus helps to maintain it. (As you may know, the original upstream author is not happy about how this is handled, but also does not put much time into vdirsyncer anymore. This makes the Debian packages even more valuable in my eyes).
* What led up to the situation? When upgrading to Buster, I've switched using vdirsyncer-latest [0.17.0a5~0+gac45bdc.d20180613] from an external package source to the standard version with buster There are three calendars configured, which are all just read_only from a CALDAV source (all on the same server) to a singlefile .ics. When trying a sync, vdirsyncer hangs on one calendar, the other two work. strace -p on the process shows futex(0x7f387429e890, FUTEX_WAIT_BITSET_PRIVATE|FUTEX_CLOCK_REALTIME, 0, NULL, FUTEX_BITSET_MATCH_ANY * What outcome did you expect instead? A complete sync or an error message, helping to diagnose the problem. This is mainly for documenting the issue first, to see if others run into the same issues. Hints and potential solutions are appreciated, of course. :) If time permitts, I'll do more analysis, possibly: * check if I can get https://wiki.python.org/moin/DebuggingWithGdb to get a better idea where it hangs in the application * try the 0.17. version with a manual install, to see if this is different (a short search on github did not reveal anything obviously related to this defect and 0.16.7 is the latest released version, even after 0.17a5.) * as it is read-only database, I may try to see, if it does away with fresh setup, though this may destroy the testable case.
