The Prisma CLI is a Node program that installs a private Node runtime on its
first invocation. That one-time install shared the 60s budget that bounds each
migration command, so on a slow or cold machine it was killed before it could
finish. Prisma then decides whether to reinstall by testing the cache
directory for existence alone, and a killed install leaves that directory
behind, so every later attempt skipped the install and failed on a node binary
that was never written. The existing four-attempt retry loop could not help:
each attempt hit the same missing binary, which turned a slow start into a
container that never migrated again.
Migrations now prepare the toolchain as its own step under its own budget, and
a cache directory that exists without a node binary is deleted first so an
interrupted install reinstalls instead of persisting. Both budgets are
overridable, LITELLM_PRISMA_BOOTSTRAP_TIMEOUT for the install and
LITELLM_PRISMA_COMMAND_TIMEOUT for each Prisma command, and every previously
hardcoded timeout now goes through one helper rather than thirteen literals.
The per-command default stays at 60s.
An override is only honoured when it parses as a finite positive number.
Infinity and NaN parse as floats and survive a plain positivity check, and
subprocess treats either as no deadline at all, so a value like `inf` or a
fat-fingered `1e400` would have silently disabled the timeout it was meant to
configure.
Logical replication consumers need FULL replica identity to reconstruct the
old row of an UPDATE or DELETE, and prisma leaves every table it creates at
the postgres default. Operators had to re-apply the setting by hand after
each migration run.
Setting LITELLM_SET_REPLICA_IDENTITY_FULL now re-asserts it on every LiteLLM
table at the end of a successful migration run, through the prisma CLI so the
dependency-free proxy-extras package stays that way. Tables that are already
FULL are skipped, foreign tables in the same schema are left alone, and a
database that refuses the ALTER is reported rather than failing the run.
