sqlite3.OperationalError: database is locked #240

Open stuart12 opened 2 years ago

stuart12 commented 2 years ago

hello, I am trying to debug https://github.com/etesync/etesync-dav/issues/206 and am being distracted by database is locked error messages. I am just importing, modifying and deleting calendar entries from a single Thunderbird instance.

This problem is on Linux running the last version of etesync-dav.

Same error here, is there a way to "unlock" the database, I think it got into a weird state while upgrading versions.

EDIT: deleting the database files (the three of them, quite arbitrarily) in the etesync data dir solved it for me.

devurandom commented 8 months ago

I encounter the same error:

  1. I stopped etesync-dav (sudo systemctl stop etesync-dav)
  2. I deleted any existing database in /var/lib/private/etesync-dav/*
  3. I started etesync-dav (sudo systemctl start etesync-dav)
  4. I added my account on http://localhost:37358/.web/add/
  5. I try to add a CalDAV in KDE PIM (http://localhost:37358/$USERNAME/) and get a 500 Internal Server Error
  6. I try to open the "collections list" (http://localhost:37358/.web/user/$USERNAME) and get a 500 Internal Server Error and a stacktrace in journald

Further observations:

  1. After listing the collections from the etesync-dav web UI, a file etebase_data.db exists and is few kilobytes in size.
  2. When trying to discover the CalDAV collections with KDE PIM, two additional files etebase_data.db-shm and etebase_data.db-wal appear.
  3. The DB grows by a few kilobytes and stops.
  4. The WAL file grows to a few hundred kilobytes and stops.
  5. KDE PIM reports etesync-dav responding with 500 Internal Server Error.
  6. The WAL file grows for a while by about 100 kilobyte per second and then stops at a size of few megabytes.
  7. The DB file jumps to a size slightly smaller than the WAL file.
  8. In KDE PIM I try to fetch the collections again and this time it succeeds and lists all collections.
  9. The WAL file still exists at (about) the same size as in step 6, even if I wait several minutes.
  10. I set the CalDAV and CardDAV URL in KDE PIM and finalize creating the Akonadi / KDE PIM resource.
  11. At the time the contacts appear in KAddressbook, the WAL file has vanished.
