New issue 268: FlushError: Instance <UserLog at 0x7f2cecab6f10> has a NULL identity key. https://bitbucket.org/conservancy/kallithea/issues/268/flusherror-instance-has-a-null-identity
Stephan Riedel: Hi, I'm currently trying to migrate the kallithea database from from sqlite to postgresql via pgloader. Kallithea version: 0.3.2 ``` #!bash # sqlite3 --version 3.8.7.1 2014-10-29 13:59:56 3b7b72c4685aa5cf5e675c2c47ebec10d9704221 # psql --version psql (PostgreSQL) 9.4.9 # pgloader --version pgloader version "3.2.2" compiled with SBCL 1.3.1.debian ``` When trying to push or pull a repository, I get an HTTP error 500 and the following stack trace in the syslog: ``` #!

If this is an auto-generated value, check that the database table allows generation of new primary key values, and that the mapped Column object is configured to expect these generated values. Ensure also that this flush() is not occurring at an inappropriate time, such as within a load() event. ``` Google tells me, that this might be connecte to the AUTOINCREMENT feature of sqlite but on first sight, all tables/columns using AUTOINCREMENT in sqlite were converted correctly to postgres (I think at least). Can you give me a hint where Kallithea is crashing or which tables might get corrupted during conversion? Also, is there any official guide on how to convert the Kallithea sqlite DB to postgres? The grate command (as proposed in the docs) requires some metadata for the migration. Where can I find it? _______________________________________________ kallithea-general mailing list kallithea-general@sfconservancy.org https://lists.sfconservancy.org/mailman/listinfo/kallithea-general
