Subject: [PATCH 01/40] [feature] Add QT4 test suite and XQuery Update support

Add qt4cg/qt4tests as a downloadable test suite (--xqts-version QT4). Parse and execute multi-step XQuery Update test cases with mutable in-memory documents. Add XP40/XQ40 spec values and XQUpdate feature. Handle revalidation and put dependency types.

Subject: [PATCH 02/40] [feature] Add XQFTTS 1.0.4 (W3C Full Text Test Suite)
 support

Add W3C XQFTTS as a downloadable test suite (--xqts-version FTTS). Handle Fragment and Inspect comparison types. Support stop-word and thesaurus URI maps with thread-safe registration.

Subject: [PATCH 03/40] [feature] Register EXPath File module for expath-file
 test set

Add exist-expath dependency and register the ExpathFileModule
(http://expath.org/ns/file) in the embedded server's conf.xml.
This resolves all 190 expath-file test failures caused by
XPST0017 "Call to undeclared function: file:exists".

Subject: [PATCH 05/40] [ci] Fix assembly build and execution for exist-expath
 dependency

- Move jetty-jakarta-servlet-api exclusion to global excludeDependencies
  so it covers transitive paths through exist-expath (fixes dedup error)
- Disable prepended shell script in CI builds (corrupts ZIP offsets,
  causing "An unexpected error" from the Java launcher)
- Use explicit java -jar in CI test step

Subject: [PATCH 06/40] [feature] Implement XQTS sandpit support for writable
 test directories

Parse the <sandpit> element from test environments, copy the sandpit
source directory to a per-test-case temp directory before execution,
set the static base URI to the temp directory so relative file paths
resolve correctly, and clean up after execution.

This enables the EXPath File test set (190 tests) and upd-fn-put
test set (17 tests) which require a writable working directory.

Subject: [PATCH 09/40] [bugfix] Use admin authentication for embedded server
 connections

Change getBroker() to authenticate("admin", "") to get an admin-level

Subject: [PATCH 10/40] [bugfix] Pass result as context item for single-item
 assert evaluations

The XQTS assert expressions like ?columns and ?get(1,1) use unary
lookup which requires a context item. Previously, the result was only
available as $result variable but not as the context item, causing
XPDY0002 errors for any assertion using the ? lookup operator.

Only set context for single-item results (e.g., maps from parse-csv)
to avoid per-item evaluation for multi-item sequences like csv-to-arrays.

Subject: [PATCH 11/40] [bugfix] Preserve namespace URI in error code
 comparison for non-standard namespaces

The runner was extracting only the local part of XPathException error
codes, losing the namespace URI. QT4 test catalogs use EQName notation
(e.g., Q{http://expath.org/ns/file}is-dir) for extension module error
codes. Now error codes from non-standard namespaces (not xqt-errors or
exist-xqt-errors) are formatted as Q{ns}local for proper matching.

Subject: [PATCH 12/40] [bugfix] Handle AllOf assertions containing Error in
 test case evaluation

When a query returns an error and the expected result is an AllOf
assertion containing an Error assertion, match the error code against
the Error inside the AllOf. Previously, only direct Error and AnyOf
assertions were matched; AllOf was not handled, causing false failures
for tests like EXPath File read-binary bounds checking where the
catalog wraps the expected error in <all-of>.

Subject: [PATCH 13/40] [bugfix] Treat assertion evaluation errors as failures,
 not runner errors
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When an XPath assertion (assert, assert-eq, assert-deep-eq,
assert-permutation, assert-serialization) raises a query error
during evaluation (e.g., XPTY0004 type mismatch), this indicates
the assertion failed — not that the runner itself errored.

Previously these were reported as ErrorResults, inflating the error
count and masking the real nature of the failure. Now they are
reported as FailureResults with the error details in the message.

Fixes fn-parse-json-717 and fn-parse-json-731 which errored due to
type mismatches in assertion XPath evaluation.

Subject: [PATCH 15/40] [bugfix] Propagate static base URI to assertion
 evaluation context
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The sandpit implementation (fab30c15) sets the static base URI for test
query execution, but assertion evaluation ran in a separate XQuery
context that defaulted to the JVM working directory. This caused 21
EXPath File tests to fail because assertion expressions like
Q{http://expath.org/ns/file}read-text("test.txt") resolved relative
paths against the wrong directory.

Thread the test case's static base URI through processAssertion → all
assertion methods → executeQueryWith$Result → connection.executeQuery,
so assertion expressions see the same base URI as the test query.

Subject: [PATCH 17/40] [bugfix] Fix test set completion detection and add
 shutdown safeguards

Fix isTestSetCompleted() to compare completed test cases against started tests rather than the full catalog (which includes test cases filtered by spec/feature requirements). Add fallback path for when ParsedTestSet is stuck in the Pekko mailbox. Prevent duplicate serialization. Reduce stall timeout from 600s to 60s with hung test reporting. Add 30-second shutdown deadline for actor system termination.

Subject: [PATCH 19/40] [feature] Add parallel batch execution to runner script

Add --parallel N flag to run-batched.sh that distributes batches across
N concurrent streams. Each stream runs in its own JVM with an isolated
eXist-db home directory (via -Dexist.home) to avoid BrokerPool data
directory lock conflicts.

Batches are distributed round-robin across streams. Results accumulate
in the same output directory (JUnit XML files have unique names per
test set, so no conflicts).

QT4 full run: 5m37s with --parallel 3 (was ~9m sequential).
FTTS verified: identical results between sequential and parallel modes.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The set +e / set -e toggle inside run_batch() caused backgrounded
subshells to exit after the first batch failure. When set -e is
re-enabled inside a function running in a backgrounded subshell,
any subsequent command failure terminates the entire stream.

Fix: replace set +e / set -e with || true pattern to capture the
timeout exit code without toggling errexit. This allows each stream
to continue processing all its batches regardless of individual
batch outcomes.

Before: --parallel 3 produced 150 results (1 batch per stream).
After: --parallel 3 produces 630 results (all 13 batches).

Subject: [PATCH 21/40] [bugfix] Normalize old map syntax (:=) in XQTS
 assertion and query expressions

The W3C XQTS 3.1 test suite uses the deprecated map{key:=value} syntax
in some assertion expressions and test queries. Since eXist-db no longer
supports := in maps, these fail with XPST0003.

Uses a heuristic: replace := preceded by a non-whitespace char (map
entries like "key":=value) but not variable bindings ($var := value
which have a space before :=).

Subject: [PATCH 23/40] [feature] Add jstack thread dump capture on batch
 timeout
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When a batch approaches its 300s timeout, automatically capture a
thread dump of the Java process via jstack. The dump is saved to
$OUTPUT_DIR/jstack-batch-N.txt, showing exactly which threads are
stuck and what locks they're contending on.

Tested with op-to (known OOM hanger): thread dump reveals Pekko
dispatcher threads BLOCKED on java.lang.Shutdown monitor — OOM'd
threads all trying to call System.exit() simultaneously, deadlocking
on the JVM shutdown lock.

 runner JVM args
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

OOM during test execution causes multiple Pekko dispatcher threads to
call System.exit() simultaneously, deadlocking on java.lang.Shutdown's
monitor. ExitOnOutOfMemoryError makes the JVM call _exit() immediately
on OOM — no shutdown hooks, no deadlock. The batch runner's timeout +
jstack handles diagnostics; the JVM just needs to die cleanly.

Subject: [PATCH 26/40] [bugfix] Exclude all Jetty transitive dependencies for
 Jetty 12 compatibility
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The runner doesn't use Jetty directly — it only needs exist-core for
XQuery evaluation. But Jetty comes in as a transitive dependency, and
Ivy can't resolve Jetty 12 Maven POM constructs (property references
in dependencyManagement), producing broken pseudo-versions.

Exclude all org.eclipse.jetty group IDs (core, toolchain, websocket,
ee10) so the runner builds against both Jetty 11 (develop) and
Jetty 12 (next) branches of eXist-db.

Subject: [PATCH 27/40] [bugfix] Fix Not assertion parsing and
 serializationMatches query building
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two bugs blocking serialization tests:

1. Not assertion parsing (9 tests): stepOutAssertions only handled
   Assertions (AllOf/AnyOf) on the stack, not Not. When </not>
   triggered stepOutAssertions with a Not(Some(...)) on top, it threw
   "Unable to associate non-assertions object". Also consolidated the
   duplicate ALL_OF end-element handler — ALL_OF, ANY_OF, and NOT are
   now handled in a single case.

2. serializationMatches query building (4 tests): The method embedded
   the expected regex in a backtick string constructor ``[...]``, but
   patterns containing <? (e.g., <?xml) trigger an eXist parser bug
   where <? is interpreted as a processing instruction start inside
   the string constructor (XPST0003). Fixed by passing the regex and
   flags as external variables.

Note: The eXist parser bug with <? inside backtick string constructors
should be investigated separately — ``[<?xml]`` should be valid XQuery.

Subject: [PATCH 28/40] [bugfix] Fix Not assertion parsing and serialization
 option extraction
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Bug 1: Not(None) inside AllOf/AnyOf — When <not> is a child of <all-of>
or <any-of>, addAssertion() appended Not() to the Assertions list, then
appended the inner assertion as a sibling instead of nesting it inside
the Not. Fix: check if the last element of an Assertions container is
Not(None) and fill it with the new assertion.

Bug 2: Serialization options lost after context.reset() — The runner
called the 3-arg XQuery.execute() which passes null for outputProperties.
eXist's execute() calls context.checkOptions(null) (no-op) then
context.reset(), clearing declared serialization options before the
runner could read them. Fix: pass a Properties object to execute() so
eXist extracts options BEFORE resetting the context. This restores
declare option output:method "html" etc. for serialization tests.

Subject: [PATCH 29/40] [bugfix] Add configurable batch timeout and process
 cleanup

- Add --timeout flag (default 180s, was hardcoded 300s) for faster
  recovery when BrokerPool shutdown hangs
- Kill lingering Java processes after each batch via pkill -9 matching
  the batch's unique exist.home directory
- Adjust jstack capture timing relative to the configurable timeout

The FLWOR fix increased rd parser test execution by ~4,483 tests,
overwhelming the batch runner with BrokerPool shutdown hangs on
13/13 batches. Shorter timeout + process cleanup allows the runner
to recover and continue.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

180s was too short for rd parser batches — the rd parser legitimately
takes longer on some test sets (FLWOR parsing complexity), causing
32/32 batches to timeout during test execution. Keep the configurable
--timeout flag and process cleanup, just set the default higher.

Exit code 1 from the XQTS runner means "some test failures found" —
normal expected behavior. Only count timeout (124/137) and crashes
(exit > 1, not 255) as batch failures. Exit 255 is a runner error
(non-fatal, produces partial results).

Subject: [PATCH 35/40] [bugfix] Add module location hints and catch namespace
 mismatches

Register addModuleLocationHint before importModule so sub-modules
can resolve their imports during compilation. Catch XPathException
from importModule to handle XQTS catalog entries that map a
namespace to a file declaring a different namespace.

Subject: [PATCH 36/40] [bugfix] Prepend xquery version per test spec
 dependency
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The QT4 XQTS catalog inherits many test cases authored against pre-XQ40
semantics (XQ10/XQ30/XQ31). Without a version declaration in the test
body, those tests run under whatever default eXist applies — typically
XQ4 in QT4 mode — which breaks tests whose expected error/result depends
on rules that changed in 4.0:

  * Reserved function names (XQ10 originally allowed `function attribute()`).
  * Default function namespace mapping for unprefixed declarations.
  * Default parameter values (`:= expr`) only legal in XQ4.
  * Subtype substitutability of xs:integer/xs:decimal.

Look at `<dependency type="spec" value="...">` on the test case and
prepend a matching `xquery version "<v>";`:

  * Any "+" form (XQ10+, XQ30+, XQ31+, XQ40+) → "4.0".
  * Strict XQ40 → "4.0". Strict XQ31 → "3.1". XQ30 → "3.0". XQ10 → "1.0".
  * No spec dep → unchanged (let ExistServer's default apply).

This restores the right outcome for ~25 prod-FunctionDecl tests that
the QT4 catalog inherits from XQ10/XQ30 with no version decl.

Also: stop calling exist-core's `addModuleLocationHint` directly. That
method was added on a newer branch and is missing on older worktrees
(e.g. v2/*), which prevents the runner from even compiling against
those branches. Use reflection so the call is a no-op when the method
is absent — the subsequent `importModule` still works either way.

Subject: [PATCH 38/40] [bugfix] Propagate testCase environment namespaces to
 assertion queries

executeQueryWith\$Result passed Seq.empty for namespaces, so XPath
assertions like \$result/*/*[1] instance of element(j:string,xs:untyped)
failed with XPST0081 even when the testCase's environment defined the
prefix (e.g. <namespace prefix="j" uri="..."/>).

Capture the current testCase's namespaces in a private actor field
when an assertion is dispatched (actors are single-threaded so this is
safe), and forward them to the embedded ExistConnection.executeQuery
call. Cleared after the assertion completes.

This unblocks ~9 fn-json-to-xml tests, ~7 op-union and op-except
"fn-*-node-args-*" assertion tests, and any other QT4 assertion that
uses a prefix declared in the test-set <environment>.

Subject: [PATCH 39/40] [bugfix] Filter QT4 tests by spec dependency to avoid
 XQ40 false failures

The QT4 runner prepends `xquery version "4.0"` to every test, then ran every
test regardless of its `<dependency type="spec" ...>`. Tests with strict
(non-"+") spec deps that exclude XQ40 -- e.g. zero-arg constructor tests
declaring `<dependency type="spec" value="XP20 XQ10"/>` and XQ10/XQ30+
test pairs like K-SeqExprCast-71a/71b -- were therefore evaluated under
XQ40 semantics, where they fail spuriously: under XQ40's focus-constructor
rule `xs:double()` is legal, so tests expecting XPST0017 see a valid result
instead.

Restrict the default enabled specs for `--xqts-version QT4` to {XP40, XQ40}
so that strict pre-XQ40 spec deps fail the dependency check and the test is
correctly recorded as AssumptionFailed rather than RUN-and-FAIL. Plus-form
deps (e.g. `XP30+ XQ10+`) continue to expand via Spec.atLeast and match
XQ40, so they still run.

Effect on prod-CastExpr (next-v3, ANTLR parser): F=34 -> F=4, with 55
additional tests now correctly skipped. Other XQTS versions (3.1, HEAD,
FTTS) keep the historical "all specs enabled" defaults.

Subject: [PATCH 40/40] [bugfix] Await in-flight TestSetResults acks during
 forced shutdown
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When the watchdog (or any other early-exit path) calls
forceSerializeAndShutdown(), the previous behaviour was to send pending
TestSetResults to the JUnitResultsSerializerRouter and immediately call
shutdown(), which terminated the actor system before the router's
children could finish writing. The in-flight messages landed in
deadLetters, causing scattered test results to silently disappear from
the JUnit output (observed: 4 prod-ModuleImport tests lost across
catalog positions 18/36/87/94 in a recent run, plus 17 pekkoDeadLetter
warnings for TestSetResults sent to terminated children).

Reuse the existing SerializedTestSetResults / FinalizeSerialization /
FinishedSerialization handshake to drain in flight before terminating:

- forceSerializeAndShutdown now sets a forcedShutdown flag, sends
  pending results, tracks them in unserializedTestSets, and returns —
  the existing ack handler triggers FinalizeSerialization once
  unserializedTestSets drains. Idempotent so repeated watchdog ticks
  cannot start parallel drains.
- SerializedTestSetResults handler relaxes its finalize trigger under
  forcedShutdown (hung-but-never-completed test cases mean
  allTestSetsCompleted() can never become true), and guards
  FinalizeSerialization against being sent twice.
- A 60s drain backstop terminates anyway if the serializer itself is
  wedged (separate from the existing 30s actor-system-termination
  backstop in shutdown()).
- shutdown() is now idempotent so the backstop's self-message and the
  normal FinishedSerialization path can't race.
