<p><strong>Each migration is one transaction, and the <code>_migrations</code> row is written

inside it.</strong> SQLite autocommits every statement otherwise, so a migration
|
||
that failed partway — low disk, an OOM kill, the process dying mid-boot —
|
||
used to leave its earlier statements applied while recording nothing.
|
||
<code>execute_batch</code> aborts on the first error, so the retry on the next launch
|
||
then failed at statement 1 (“duplicate column name”) and kept failing
|
||
forever; <code>Database::open</code> turns that into a panic, so the app never
|
||
started again and the only fix was clearing app data. Committing the
|
||
schema change and the bookkeeping together makes a migration all-or-nothing
|
||
and a retry always safe.</p>
|
||
<p>Every migration is pure DDL/DML, which SQLite runs transactionally — a
|
||
<code>PRAGMA</code> or <code>VACUUM</code> added to one would not roll back and must not be.</p>
|
||
<p>Runs on the bare connection, before the writer thread takes it, so
|

tests can also inject a failing migration through <code>migrate_with</code>.</p>
