…nly log DocumentationDatabaseVersion holds exactly one row -- the format version the database *is*, not a history of what it has been. The comments and the doc bullet described an append-only log, which was my reading of the ticket's INSERT-based update example and is wrong. resolveMajorVersion keeps ORDER BY rowid DESC, now stated as a defence rather than a model: a file that breaks the one-row contract still reads deterministically, and a downgrade still reads as a downgrade where MAX(major) would report the highest version ever declared. The two tests that asserted last-row-wins across several rows collapse into one that says what that ordering is actually for. The writer side is OfflineDocumentationTools#29.

The reader tolerates several rows on purpose -- ordering by rowid keeps the answer deterministic -- but it did so silently, so a database built by something that appended instead of replacing looked identical to a correct one. The count now rides along with the version in the same query, and more than one row is logged with the major actually used. The doc bullet stated the one-row rule twice over nine lines; it now says it once. Verified: the query returns (last major, total count) against sqlite directly, for one row, several rows, and none. The instrumented assertion for the single-row path is added but not executed -- no device is attached at the moment. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…orst case Review of this PR found that merging the two ordering tests deleted the only one that distinguished "highest rowid" from "lowest major": every remaining expectation happened to be the minimum major present, so MIN(major) would have passed the whole suite while the test named for the row written last proved nothing. Both directions are back -- the last row higher, and the last row a downgrade. The NULL check ran before the count was read, so a file that is both multi-row and ends in a NULL major returned null with nothing logged: the most malformed state there is, reported exactly like a database that has no version table. The count is read first now, and there is a test, which needs a table created without the shipped DDL's NOT NULL -- fitting, since this reader exists to defend against files another producer wrote. WebServerTest's cursor stub never answered getInt(1), so a relaxed mock returned a row count of 0 -- a state the production code has just excluded by getting a row back at all. It returns 1 now, so those tests exercise something reachable. The doc claimed docdb-studio logs a warning for a multi-row file. It does not; only this reader does. It also lost the reason highest-rowid beats MAX(major), which is the fact that stops someone simplifying the query later. Both fixed. Verified on device this time, not just compiled: 12 instrumented tests pass on a Galaxy Note 20 Ultra, and the warning appears three times in logcat -- once per multi-row case, the NULL-major one included.

This file was one of two in common/utils still using android.util.Log where ten
siblings use SLF4J, so the whole file moves rather than just the new warning --
a file mixing both would be worse than either. The duplicate-row warning takes a
{} placeholder with rows as an argument.
The malformed-table fixture built its INSERT by concatenating literals; the
values are bound now, like every other insert in this test.
Verified on device: 12 instrumented tests pass and the warning still reaches
logcat three times through the SLF4J binding.

Review follow-ups on the single-version-row reader. ORDER BY rowid DESC picked "the row written last" only by accident: rowid is not insertion order, and SQLite is free to reuse the rowid of a deleted row. The table carries a changeTime column that records exactly what the comment claims to want, so order by that and let rowid break ties. On a downgrade -- major 3 written, then 2 -- the old ordering could hand back 3 and attach the shared dictionary to content that is plain brotli. A NULL major now logs. It still reads as "no declared version", because that is the answer the caller is built to handle, but it and a database predating the table are no longer indistinguishable in the log: one is an old file behaving correctly, the other is a malformed one silently losing dictionary decoding. formatVersion returned "" when changeTime, set and who were all blank, which callers stored and displayed as a stamp. Return VERSION_UNKNOWN. The existing tests are in common/src/androidTest, which no workflow runs -- CI assembles :app:assembleV8DebugAndroidTest and runs two named app classes. The branch logic now has JVM tests that execute. Four of them pin behaviour that was already correct but unproven; the ordering test fails against the previous query.

The intro still credited Tier 3 solely to WebServer; since ADFA-5176 the interceptor serves it in-process with WebServer as the HTTP fallback. And DocumentationContentSource is the one *Tier 3* pipeline reading the database -- ToolTipManager reads it too, as the section intro itself says.

DocumentationDatabaseVersionholds exactly one row — the format version the database is, not a history of what it has been. The comments and the doc bullet merged in #1726 described an append-only log instead. That was my reading of ADFA-5220'sINSERT-based update example, and it was wrong.No longer just comments. That was true of the first commit; since then this PR changes the query (the row count now rides along with the version), adds a
rows > 1warning, and fixes the order of the NULL check — so the behavioural part deserves a real look rather than the "comments only" skim the original summary invited.Verified on hardware: 12 instrumented tests pass on a Galaxy Note 20 Ultra, and the warning appears three times in logcat — once per multi-row case, including a file whose last row has a NULL major.
The query stays; its justification changes
resolveMajorVersionkeepsORDER BY rowid DESC LIMIT 1, now stated as a defence rather than a model. Nothing in the DDL enforces the one-row rule, so if a file ever turns up carrying several rows, this reads the one written last rather than whichever SQLite happens to return — and a downgrade still reads as a downgrade, whereMAX(major)would report the highest version the file ever declared.The two tests asserting last-row-wins across several inserted rows became one test saying what that ordering is for:
majorVersionIsTheRowWrittenLast_whenADatabaseCarriesSeveral.Writer side
OfflineDocumentationTools#29 now replaces the row instead of appending, and collapses a database that accumulated several back to one — so a file that broke the contract gets repaired the next time the pipeline touches it, rather than being read around forever.
