Prose and benchmark tables use MultiforaDB; the binary, the CLI usage
line, the log-message prefix and the default database file use
multiforadb.
Two consequences worth noting:
- build.zig.zon's fingerprint is derived from the package name, so it
had to change with it (Zig refuses to build otherwise). A consumer
pinning this package by fingerprint needs updating.
- the default --db path is now multiforadb.log, and getCmdLineOpts
reports it as dbpath. An existing mongo-lite.log has to be passed
explicitly with --db.
The e2e harness abbreviated the old name as ML_; that is now MFDB_,
including the documented ML_BIN override (MFDB_BIN) and the scratch
file names. MD_ (mongod) is untouched.
compare-run.sh spawned the server by absolute path under a
sandbox/mongo-lite directory that no longer exists; that block already
runs from tests/e2e, so it uses a relative path now.
The archived reports under tests/e2e/results/ keep the old name: they
record what the old binary measured.
compare-run.sh answers "how do we compare to MongoDB"; it says nothing
about whether a change made things better or worse than last week. Add a
harness that records each run and diffs it against the previous one.
bench-run.sh wraps compare-run.sh, adds a concurrent durable-write
comparison (concurrent.js: N clients each doing sequential insertOne with
{w:1, j:true}, exercising the group-commit path under real contention),
writes a versioned name<TAB>value report to results/bench-<timestamp>.txt,
and prints a diff of our numbers against results/bench-latest.txt.
Also:
- compare-run.sh polled with fixed sleeps, which are flaky once earlier
benchmark phases have warmed the machine; both servers now wait on a
real driver connection instead.
- a dispatch error only reached the client as a generic InternalError,
with nothing on the server side naming the failing command; log the
connection, command and error name before replacing the reply.
