Currently, I am working on [this](https://gitlab.com/mailman/mailman/merge_requests/528) PR. A problem arose with some SQLite tests and I made changes to the latest migration file. This is my output of `alembic -c src/mailman/config/alembic.cfg history` command >2d2d0ef0828f -> 58858f75303c (head), Added new bounce attributes >15401063d4e3 -> 2d2d0ef0828f, add tag column >b2e694dfde35 -> 15401063d4e3, roster_visibility >89913992dd5a -> b2e694dfde35, unique email contraint >dfe82cf73702 -> 89913992dd5a, remove mime_is_default_digest >3f31035ed0d7 -> dfe82cf73702, add_alias_domain >4bd95c99b2e7 -> 3f31035ed0d7, further_increase_pendedkeyvalue_value_size >3002bac0c25a -> 4bd95c99b2e7, Fix template password field. >a46993b05703 -> 3002bac0c25a, dmarc_attributes >448a93984c35 -> a46993b05703, increase pendedkeyvalue value size >fa0d96e28631 -> 448a93984c35, unsubscription_workflow >7b254d88f122 -> fa0d96e28631, File cache and template manager. >d4fbb4fd34ca -> 7b254d88f122, Members and list moderation action. >bfda02ab3a9b -> d4fbb4fd34ca, Add a numerical position column to sort header >matches. >781a38e146bf -> bfda02ab3a9b, Ban indexes >70af5a4e5790 -> 781a38e146bf, MailingList indexes >47294d3a604 -> 70af5a4e5790, digests >3e09bb4a5dc -> 47294d3a604, Pendable indexes >33bc0099223 -> 3e09bb4a5dc, Add indexes on the Member table. >42756496720 -> 33bc0099223, Add member indexes >2bb9b382198 -> 42756496720, header_matches >16c2b25c7b -> 2bb9b382198, Workflow state table >46e92facee7 -> 16c2b25c7b, List subscription policy >33e1f5f6fa8 -> 46e92facee7, add_serverowner_domainowner >51b7f92bd06c -> 33e1f5f6fa8, Migration from Python 2 to Python 3. ><base> -> 51b7f92bd06c, Initial migration.
On doing `alembic -c src/mailman/config/alembic.cfg current -v` >Current revision(s) for >sqlite:////home/aaryan/mailman/mailman/var/data/mailman.db: >Rev: 2d2d0ef0828f >Parent: 15401063d4e3 >Path: >/home/aaryan/mailman/mailman/src/mailman/database/alembic/versions/2d2d0ef0828f_add_tag_column.py > > add tag column > > Revision ID: 2d2d0ef0828f > Revises: 15401063d4e3 > Create Date: 2019-04-27 08:58:48.496854 But when I run `alembic -c src/mailman/config/alembic.cfg upgrade head`. It gives a long traceback, the main gist of which is >sqlalchemy.exc.OperationalError: (sqlite3.OperationalError) duplicate column >name: bounce_info [SQL: 'ALTER TABLE address ADD COLUMN bounce_info BLOB'] >(Background on this error at: >http://sqlalche.me/e/e3q8) The whole traceback is [here[(https://gist.github.com/berserker1/6b214626042a6c976f780b33d2d12f32) I did `alembic -c src/mailman/config/alembic.cfg downgrade 2d2d0ef0828f` to ensure it has restored to the previous version but still, again the error pops up Basically, Alembic is not able to properly downgrade and hence recognising a duplicate column when I upgrade. Any pointer to this would be helpful. _______________________________________________ Mailman-Developers mailing list -- mailman-developers@python.org To unsubscribe send an email to mailman-developers-le...@python.org https://mail.python.org/mailman3/lists/mailman-developers.python.org/ Mailman FAQ: https://wiki.list.org/x/AgA3 Security Policy: https://wiki.list.org/x/QIA9
