/pr/bs returned HTTP 500 on a Galaxy Note 20 Ultra (Android 13): no such function: JSON_OBJECT. The query was fine — it runs against the same documentation.db under desktop sqlite3 3.44 — but that device's system SQLite has no JSON1 extension, so the Dynamic Bookshelf could not be opened at all. Every desktop test passes, so nothing catches this before hardware.

The fix

The payload is now assembled from a plain relational query plus gson, which work everywhere. Same keys, same nesting, same explicit nulls (gson gets serializeNulls, because JSON_OBJECT emitted "description": null and the template was written against that), and the same 1/0 pdf flag rather than a boolean.

readBookshelf() takes the database as a parameter so the payload is testable without starting a server. Twenty-one tests across two classes cover the grouping and order, the pdf flag, the empty bookshelf, and the exact JSON string the template receives.

Two behavior differences, both improvements:

  • An empty bookshelf renders as an empty page instead of failing. The old query turned it into a 500: group_concat over no rows is NULL, so the concatenated JSON was NULL and reading it as a blob threw. Not hypothetical — see below.
  • A path ending .PDF is flagged as a PDF. The old SUBSTR comparison was case-sensitive; all 15 PDFs in the database are lowercase, so nothing changes today.

Grouping keys on the raw category, so a NULL category and a literal "General" stay two separate groups that both render as "General" — deliberately, because that is what the query this replaces did (it grouped by BC.category while coalescing only in the payload). an unlabelled category and a literal General stay separate groups pins it. An earlier draft of this description claimed the opposite.

Verified on device

Fresh install of a build with this fix stacked on ADFA-5176 (which carries ADFA-5153, needed to decode this database's templates at all):

  • /pr/bszero JSON_OBJECT errors in logcat, where before it was a 500 naming that function. The payload assembly runs to completion.
  • /pr/db 200, /pr/ex 200, /pr/pr 200 — the other developer endpoints are unaffected.

What this does not fix, which is worth knowing

The bookshelf still doesn't render on that device, for two data reasons — the endpoint now returns 404 instead of 500:

  1. Bookshelf.bookCategoryID is NULL on all 15 rows, so the content join is empty.
  2. There is no bookshelf row in Templates at all — it holds three: layout.pebble, nav.peb, page.peb. That lookup is what 404s.

This is not a stale developer file: the app was uninstalled and reinstalled from scratch, and its freshly provisioned database is byte-identical to the sdcard copy (md5 34c8795…), so a clean device gets a database that cannot render a bookshelf. Fixing that belongs in docdb-studio, not here — details on ADFA-5179.

Testing

:app:assembleV8Debug, spotlessCheck and the full :app unit-test suite pass. One wrinkle found and fixed along the way: the new test class left mockk's instrumentation installed, which broke BrotliDictionaryDecodeTest's @BeforeClass native load later in the same JVM — reproduced both directions, fixed with the unmockkAll() teardown every other mockk test in the module already has.

…SON1
/pr/bs returned HTTP 500 on a Galaxy Note 20 Ultra (Android 13): "no such
function: JSON_OBJECT". The query was fine -- it runs against the same
documentation.db under desktop sqlite3 3.44 -- but that device's system SQLite
has no JSON1 extension, so the bookshelf could not be opened at all. Nothing
catches this before real hardware, since every desktop test passes.
The JSON is now assembled from a plain relational query and gson, which work
everywhere. Same keys, same nesting, same explicit nulls (gson gets
serializeNulls, because JSON_OBJECT emitted "description": null and the bookshelf
template was written against that), and the same 1/0 pdf flag rather than a
boolean.
Two behavior differences, both improvements, neither reachable in the data seen
so far:
- An empty bookshelf now renders as an empty page instead of failing. The old
query turned it into a 500: group_concat over no rows is NULL, so the
concatenated JSON was NULL and reading it as a blob threw. That case is not
hypothetical -- the sdcard documentation.db copy on the test device has a NULL
bookCategoryID on all 15 Bookshelf rows, so the join yields nothing and the
endpoint would have failed there even with JSON1 present.
- A path ending .PDF is flagged as a PDF. The old SUBSTR comparison was
case-sensitive; the 15 PDFs in the database are all lowercase, so this changes
nothing today.
Grouping also collapses a NULL category into an existing "General" rather than
producing two sections with the same name, since it groups by the coalesced label
instead of the raw column.
readBookshelf() takes the database as a parameter so the payload is testable
without starting a server. Four tests cover the grouping and order, the pdf flag
including the case difference, the empty bookshelf, and the exact JSON the
template receives.
Not yet verified on device: the phone was disconnected before this could be
installed. What needs checking is that /pr/bs returns 200 both against the sdcard
copy (expect an empty bookshelf, given its data) and against the installed asset
database with the sdcard copy moved aside (expect real content).
The new test class left mockk's instrumentation installed for the rest of the
JVM, and the next test to run in it -- BrotliDictionaryDecodeTest -- then failed
in @BeforeClass with 'Failed to load Brotli native library'. Reproduced both
ways: the full app suite passes with this class excluded and fails with it
included, deterministically.
Every other mockk-using test in this module already unmocks in teardown; this one
just missed it.

📝 Walkthrough
  • Replaced SQLite JSON1 payload construction with relational queries and Kotlin Gson serialization.
  • Fixed /pr/bs HTTP 500 errors on Android devices without SQLite JSON1 support.
  • Preserved JSON keys, nesting, explicit nulls, query ordering, and numeric pdf flags.
  • Kept unlabeled categories separate from categories named "General".
  • Preserved the first category description, including a first-row null description.
  • Skipped and logged rows with null Content.path using the content ID.
  • Added empty-bookshelf handling and case-insensitive .PDF detection.
  • Added real SQLite query tests and expanded payload tests for grouping, ordering, null values, paths, PDF detection, empty shelves, UTF-8 data, and exact JSON output.
  • Centralized test server configuration.
  • Documented the SQLite JSON1 limitation and the recommended Kotlin JSON assembly approach.
  • Verified :app:assembleV8Debug, spotlessCheck, and the full app unit-test suite.
  • Device verification found no JSON_OBJECT errors.
  • Remaining 404 responses require bookshelf data and templates in the database.
  • Risk: The implementation uses an object-to-string-to-bytes-to-string-to-map JSON round trip.
  • Risk: Class-wide serializeNulls() and positional column indices can increase maintenance risk.
  • Risk: The relaxed empty-shelf mock may not fully model production query behavior.

Walkthrough

The bookshelf endpoint now assembles ordered relational query rows into JSON. It preserves null descriptions, separates null and "General" categories, skips rows with null paths, and logs content IDs for skipped rows. Tests cover SQLite queries, payload serialization, and shared test configuration.

Changes

Bookshelf flow

Layer / File(s)Summary
Bookshelf payload assembly
app/src/main/java/com/itsaky/androidide/localWebServer/WebServer.kt, docs/documentation-database.md
Defines internal payload models and explicit JSON names. Builds ordered category groups from relational rows, preserves null descriptions, detects PDF paths case-insensitively, skips null paths, logs content IDs, and serializes UTF-8 JSON without SQLite JSON1 functions.
SQLite query validation
app/src/test/java/com/itsaky/androidide/localWebServer/BookshelfQueryTest.kt
Tests column mapping, inner-join behavior, fallback "General" labels, title ordering, and empty databases against SQLite.
Payload and test configuration validation
app/src/test/java/com/itsaky/androidide/localWebServer/BookshelfPayloadTest.kt, app/src/test/java/com/itsaky/androidide/localWebServer/TestServerConfig.kt, app/src/test/java/com/itsaky/androidide/localWebServer/WebServerTest.kt
Tests category grouping, first-row descriptions, null-path skipping, UTF-8 JSON, and shared test-safe server configuration.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk:🟡 Moderate · up to 84988

Uncategorized bookshelf entries can still be omitted from the generated payload despite the intended General-category fallback, which may produce incomplete shelves for affected databases; merge should wait for that correctness issue to be fixed or explicitly accepted.

Review pointed at IFNULL(BC.category, 'General') and read it as dead code,
on the grounds that the join already drops a book whose bookCategoryID is
NULL. The join does drop those -- deliberately, since that is what the query
this PR replaced did -- but the IFNULL is not about them: BookCategories.category
has no NOT NULL constraint, so a book can be linked to a category row that has no
label, and that is the case it covers.
Both of the query's fallbacks are now expressed in Kotlin instead, which makes
which case each one handles visible at the point it applies, and lets a test pin
them: a category row with no label files its books under General, and a book with
no title of its own shows its path. Neither was covered before, because the SQL
is not exercised by unit tests -- the cursor is mocked.
Behavior is unchanged in every case.

The review is right. The old JSON1 query grouped by BC.category and applied
IFNULL(BC.category, 'General') only when building the payload, so a category row
with no label and a row labelled "General" were two groups that both rendered as
"General", each with its own description. Coalescing before grouping merged them
and kept whichever description came first.
The maps are now keyed by the raw nullable category and the label is applied when
the BookshelfCategory is constructed. This PR is a port whose whole claim is that
the payload is identical, so a behaviour change here -- even a defensible one --
does not belong in it.
Latent rather than live: no BookCategories row in the current database has a NULL
category. The column is nullable, so the case is reachable.

…a path
Three findings from the review of this PR.
putIfAbsent was the wrong tool for "the first description wins".
java.util.Map counts a key mapped to null as absent -- HashMap.putVal
only skips the write when oldValue != null -- so a category whose first
row had a NULL description was overwritten by whatever the next row
carried, which is the opposite of what the comment claimed and what the
query this replaced did. The two parallel maps keyed by the same
category are now one map of a small holder, so the description is read
once, when the group is created, and nothing can write it again. That
also removes the second lookup per row and the possibility of the two
maps disagreeing. The holder's type has to stay non-null for this to
hold: getOrPut treats a null value as absent too, so a map of nullable
descriptions would reintroduce the same bug in a different shape.
A NULL Content.path took the whole endpoint down. cursor.getString(4)
is a platform type, so handing it to BookshelfBook(link: String)
inserts an intrinsic null check -- an NPE caught upstairs as an HTTP
500 for every book on the shelf, where the old SQL degraded to
"link": null for the one row. The schema says NOT NULL and the
maintained database honours it, but this endpoint exists because a
shipped copy had NULLs nobody expected. The row is skipped and logged.
Bookshelf, BookshelfCategory and BookshelfBook are internal rather than
public. They are one endpoint's payload shape, and common's classes
ship in the plugin-api coordinate; three very generic names did not
belong in that surface. internal, not private: a private top-level
class cannot be the return type of an internal function, and the tests
in this module read them.
Three tests added. Two of them fail against the code as it stood --
"expected: null but was : Arrived late" and a NullPointerException --
for the reasons they are named for. 276 app tests pass.
Found in review of PR #1700.

Pushed b9f337b (rebased onto the stage merge that just landed). Three findings from review.

putIfAbsent was the wrong tool for "the first description wins".java.util.Map counts a key mapped to null as absent — HashMap.putVal only skips the write when oldValue != null — so a category whose first row had a NULL description was overwritten by whatever the next row carried. That is the opposite of what the comment claimed and of what the query this replaced did.

Fixed structurally rather than with a guard: the two parallel maps keyed by the same category are now one map of a small holder, so the description is read once, when the group is created, and there is no second write to get wrong. It also drops the second lookup per row and removes the chance of the two maps disagreeing.

Worth knowing for anyone touching this later: the holder's type has to stay non-null. getOrPut treats a null value as absent too, so a LinkedHashMap<String?, String?> of descriptions would reintroduce the identical bug in a different shape — which is why the narrow containsKey fix would have been the more fragile one.

A NULL Content.path took down the whole endpoint.cursor.getString(4) is a platform type, so passing it to BookshelfBook(link: String) inserts an intrinsic null check — an NPE, caught upstairs as an HTTP 500 for every book on the shelf, where the old SQL degraded to "link": null for the one row. The schema says NOT NULL and the maintained database honours it, but this endpoint exists precisely because a shipped copy had NULLs nobody expected. That row is skipped and logged now.

The three payload classes are internal. They are one endpoint's payload shape with very generic names, and common's classes ship in the plugin-api coordinate. internal rather than private, because a private top-level class cannot be the return type of an internal function and the tests read them.

Three tests added; two fail against the code as it stood — expected: null but was : Arrived late and a NullPointerException — for the reasons they are named for. 276 app tests pass.

Separately, this PR's bug reproduces on real hardware. On a Galaxy Note 20 Ultra running the current build, /pr/bs returns HTTP 500:

E SQLiteLog: (1) no such function: JSON_OBJECT in "SELECT '{"result" : [' || group_concat(Item) ...

The same database served the same query fine under desktop sqlite3 3.44.4 minutes earlier — which is the constraint this PR is about, and the reason it is worth landing. It also gates on-device verification of #1707, since the bookshelf template cannot render until the payload builds.

Still open from the review, not addressed here: the JSON round-trip (object → string → bytes → string → map) that forces serializeNulls() onto the class-wide gson shared with the Tier 3 path, the gsonForTest accessor whose test re-composes the pipeline instead of pinning the production one, the positional column indices over two columns both named description, and the relaxed mock that makes an empty bookshelf is an empty list unfalsifiable.

One doc gap worth closing before this merges: the JSON1 constraint lives only in readBookshelf's KDoc. docs/documentation-database.md opens with "read this before writing SQL against this database" and has a Known rough edges section that does not mention it — so the next person writes JSON_OBJECT in a tooltip query, validates on desktop, and ships a 500 that only appears on a device. Happy to add the bullet if you want it in this PR.

Reviewed at depth against b9f337b. The core change is right: dropping JSON1 is the correct fix for the ticket, the relational query is the one I would have written, and the KDoc explaining why earns its space.

b9f337b landed while I was reading, and it already fixes four things I had written up -- putIfAbsent, the NULL-path NPE, the two parallel maps, and the over-broad visibility. Everything below is re-verified against that commit, not the one before it.

Two things I would want resolved before merge.

  1. The payload is not identical. The KDoc at WebServer.kt:1049 says it is. I ran the old JSON1 query and the new one side by side against the current documentation.db and found two real differences: book ordering within a category (line 1071) and case-insensitive .pdf matching (line 1122). Neither is wrong -- the new ordering is arguably better -- but both should be stated rather than described as a no-op, or someone will file the swapped Java books as a regression.

  2. The gson field names are unprotected against R8 (line 66). They are the JSON keys the Pebble template reads by name, and only the temporary-dontobfuscate/-dontshrink in proguard-rules.pro is holding them up -- the block labelled "revert once ADFA-5156 lands a targeted fix".

Worth weighing: no test executes the new SQL (BookshelfPayloadTest.kt:52). The mock intercepts on a substring and returns canned rows, so the query text, the column order and the ORDER BY are all uncovered -- on a ticket whose subject is SQL that only failed on real hardware. Details inline.

One finding I cannot leave inline, since the file is not in the diff:docs/documentation-database.md. Line 85 still describes the bookshelf payload in its old shape, and the Known rough edges section at line 105 is the natural home for "JSON1 is absent from the system SQLite on some devices". That constraint currently lives only in a KDoc -- a repo-wide grep finds no other JSON1 use, so this is the only place the lesson is written down, and the next person writing SQL against this DB will reach for it again and reproduce the Note 20 Ultra failure. CLAUDE.md asks for docs to move with the code, or a ticket if that is out of scope.

The rest is smaller: one wasted JSON round trip, a test-only accessor, and some test-fixture duplication.

Review findings from hal-eisen-adfa.
The KDoc claimed the payload was identical. It is not, in two ways,
both checked against the shipped database rather than reasoned about:
Books within a category are now genuinely sorted by title. The old
ORDER BY was inert for them -- it ordered the groups, while
JSON_GROUP_ARRAY aggregated in scan order and B.title was a bare column
under GROUP BY. Against the current documentation.db this reverses the
two Java books, since a space sorts before a comma. Deterministic order
is worth having; claiming nothing changed is not.
The pdf flag is now case-insensitive, where SUBSTR(path, -4) == '.pdf'
compared under BINARY collation. No shipped row spells the extension
any other way -- GLOB '*.[Pp][Dd][Ff]' excluding '*.pdf' returns zero --
so nothing changes today, but the widening was undocumented.
Nothing ran the new SQL. The existing tests hand readBookshelf canned
cursor rows through a mockk matcher, so the column order, the joins and
the ORDER BY were never executed -- on a ticket whose whole subject is a
query that passed on a desktop and failed on a device. BookshelfQueryTest
runs it against a real SQLite database. It earns its place: reordering
the two columns both named `description` in the SELECT list, leaving the
reader alone, fails that test and leaves all ten mock-based tests green.
gsonForTest is gone. The test that pinned the payload's keys, nesting
and explicit nulls asserted on a re-composed
gson.toJson(readBookshelf(...)) -- the same expression as production,
which is not the same thing as the production path, and could not fail
if that line changed. Both now call bookshelfJson().
An empty shelf is logged. It is a 200 with an empty page either way, but
it was indistinguishable from a working shelf in a bug report, and it is
the state ADFA-5204 produced.
The JSON keys are pinned with @SerializedName instead of being derived
reflectively from field names. The template reads them literally, so a
renamed field is a page of blanks with nothing failing. -dontobfuscate
currently keeps them intact, but that is a global build flag two open
tickets are changing, not a contract this payload should rest on.
ServerConfig's eight fields were copied field-for-field between two test
classes in the same package; both now call testServerConfig().
281 app tests pass.
Still open from the same review: the JSON round trip through text that
instantiatePebbleTemplate immediately parses back into a map, which
needs an overload taking a prepared context; and the unmockkAll coupling
with BrotliDictionaryDecodeTest, which wants a shared rule rather than a
copy per class.

The warning said "Bookshelf row for content id {}" and logged
cursor.getString(2), which is B.title -- the SELECT had no C.id. It
pointed a reader at the wrong column while diagnosing the malformed-data
case the branch exists for, and in that branch the title is often null
too, so it identified nothing while claiming to.
C.id is appended to the SELECT, not inserted: every read here is by
positional index, so a column added anywhere else silently re-points the
four above it.
The cursor mock now answers a missing index with null rather than
throwing, so a test row need only give the columns its case cares about,
the way a NULL column would read.
308 app tests pass.
Found in review of PR #1700.

1057-1062: 📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

Use a message that covers skipped rows.

readBookshelf skips rows whose Content.path is NULL at Lines 1143-1148. If every matched row has a NULL path, this branch logs that the query matched no rows even though it did return rows. Change the message to state that no categories remained after filtering, or return matched/skipped counts if that distinction is required.

Proposed fix
- log.info("Bookshelf query matched no rows; serving an empty shelf.")+ log.info("Bookshelf produced no categories after filtering; serving an empty shelf.")

The empty-shelf log claimed the query matched no rows. A row whose
Content.path is NULL is skipped a few lines below, so the query can
return rows and still leave nothing to serve -- in which case the line
said something false about the database while diagnosing the case it
exists for. It reports no categories now, and each skipped row already
logs its own warning, which is what distinguishes the two states.

Picking up the one finding from the 18:48 review that landed outside the diff and so has no thread of its own — WebServer.kt 1057-1062, the empty-shelf log.

It's right, and it's about the line I added in the previous round. A row whose Content.path is NULL is skipped a few lines below, so the query can return rows and still leave nothing to serve — in which case "Bookshelf query matched no rows" says something false about the database while diagnosing exactly the malformed-data case it exists for.

Fixed in fe66bbc: it reports no categories rather than no rows, with a comment recording why the distinction matters. I didn't add matched/skipped counts, because each skipped row already logs its own warning naming the content id — so the two states are already distinguishable in a log, and a count would restate what those warnings say.

15 bookshelf tests pass.

For the record on the rest of that review round: the two threads still open on this PR are open on purpose, both answered above — the JSON round trip (needs an instantiatePebbleTemplate overload that takes a prepared context; it touches the path every documentation page renders through, and this PR has to be trusted not to change the page) and the unmockkAll coupling with BrotliDictionaryDecodeTest (module-wide, wants a shared rule rather than a copy per class). Neither is forgotten; both are deliberately not passengers here.

The constraint this ticket exists for lived only in readBookshelf's
KDoc. docs/documentation-database.md opens with "read this before
writing/editing SQL against this database" and carries the list of
gotchas found writing these scripts, and said nothing about it -- so the
next person writes JSON_OBJECT, validates it under sqlite3 3.44 where
JSON1 is built in, and ships a 500 that only appears on a device.
The bullet says which functions, what the failure looks like, that the
desktop will not warn you, and that every reader of this database is
exposed -- a docdb-studio script, ToolTipManager, and
PluginDocumentationManager as much as WebServer.
Prompted by reproducing it on hardware while testing PR #1707: /pr/bs
returned HTTP 500 with "no such function: JSON_OBJECT" on a Galaxy Note
20 Ultra, minutes after the same database served the same query fine
under the desktop CLI.
…s a category
Review findings, all in the parts of this change that alter what a user
sees.
The books were sorted on B.title but displayed as B.title ?: C.path, and
under BINARY collation with NULLs first that is a different order: an
untitled book rendered as its path at the top of its section, and every
capitalised title sorted ahead of every lower-case one. ORDER BY now
uses COALESCE(B.title, C.path) COLLATE NOCASE, so the sort key is the
string on the page. The KDoc claimed the books were "genuinely sorted by
title" with no qualification; the new test fails against the old clause,
putting d/zebra.pdf first.
A category whose books all have a NULL Content.path now disappears
entirely. The old query emitted the section with "link": null in it --
broken but present -- because it built JSON per row before any
filtering; skipping the row here happens before its group exists. The
skip is still right, but it was a fourth behaviour change absent from
the KDoc's list of three. Now listed, and pinned by a test.
Both new log lines are gated on debugEnabled, like everything else on
this path. On the database this ticket exists for -- every Bookshelf row
joining to nothing -- the empty shelf is the steady state, so the info
line fired on every page load, and the per-row warning was unbounded.
BookshelfCategory.books is handed a copy. It is typed as a List but was
the accumulator's own MutableList, which a future caller that keeps the
map could mutate afterwards.
Also: a test now pins that an empty shelf serialises to {"result":[]}
rather than something blank -- instantiatePebbleTemplate throws for a
blank or "null" context, and that guard sits outside this endpoint's
try/catch, so the empty-page promise depended on a property nothing
checked. And a comment miscounted the columns preceding C.id as four.
310 app tests pass.
