Stale shrunk-snapshot on re-configure -> configure fingerprints the classpath jars (path+size+CRC) and wipes shrunk-classpath-snapshot.bin plus ic/ when the bytes changed, keeping them when identical. Covered by IncrementalCompilerTest "re-configuring over an in-place rewritten classpath jar discards the stale shrunk snapshot" and its byte-identical keep-warm companion. 2. "Deployed" baseline that no deploy ever acks -> deployedOutputs renamed to lastGoodOutputs with honest KDoc, and a compile declaring EVERY source changed now rebaselines: the output diff runs against nothing and reports the whole tree, giving clients a wire-compatible recovery after a failed dex/deploy. Covered by IncrementalCompilerTest "declaring every source changed rebaselines - the whole output tree is reported changed". ROUTED(qb-08 core-orchestration / qb-11 app): the orchestrator must still force a full-changed compile (ChangedFiles.Unknown) after a failed dex/deploy; today it only re-queues the batch. No protocol-module change. 3. d8 diagnostics not captured -> a DiagnosticsHandler proxy is installed via D8Command.builder(handler); collected error diagnostics are appended (bounded) to the Failed message instead of the bare "Compilation failed to complete". Covered by DexToolEdgeTest "a d8 failure surfaces d8's own error diagnostics, not only the generic message" (runtime-compiled fake r8, runs untethered). 4. Silent stable-ids degrade -> relink fails a named-but-missing stableIds file before aapt2 runs; only an explicit null links unpinned. Covered by Aapt2LinkEdgeTest "a named but missing stable-ids file fails the relink instead of silently linking unpinned".

📝 Walkthrough
WalkthroughThe PR adds a packaged QuickBuild daemon with a line-delimited JSON protocol, persistent compilation sessions, incremental Kotlin/Java compilation, reflective D8 dexing, AAPT2 resource relinking, toolchain discovery, and extensive unit and integration coverage. ChangesQuickBuild daemon
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟡 Moderate · up to The daemon's new resource relinking path can overwrite compiled resources when multiple roots contain the same relative file, producing incorrect builds. This is a bounded but material correctness risk, so the PR is not merge-ready until the roots are isolated or multiple roots are rejected. Sequence Diagram(s)sequenceDiagram

ProtocolCodecTest.Every other new test class in this module carries class KDoc that states the contract under test. This class has none, and it is the largest codec suite (round-trip, optional-field defaults, stats version-safety). Add two or three lines that state the contract: parse maps each op to its typed request, absent optional fields take documented defaults, and encode produces exactly one line with an additive stats shape.
The coding guidelines require KDoc on public classes documenting the contract and the why. Based on learnings, individual backticked test methods do not need their own KDoc once the class KDoc exists.

63-79: 🩺 Stability & Availability | 🔵 Trivial | 💤 Low valueDrain the child stdout and stderr concurrently, or redirect stderr to a file.
The test reads stdout to EOF first, then stderr. The daemon redirects
System.outonto stderr, so anything the compiler or the JVM prints lands on the child stderr. If that output ever fills the OS pipe buffer, the child blocks writing stderr, never closes stdout, and the parent blocks inreadBytes(). The 60-second preemptive timeout turns that into a flaky failure rather than a hang.The shutdown-only request keeps the current volume small, so this is a latent risk, not a present failure. A file redirect removes the coupling for one line of change.

- Around line 159-168: Update the AAPT2 compilation flow around run and
flatFiles so each resDir compiles into its own uniquely named subdirectory,
preventing identical relative resources from overwriting one another. Collect
.flat outputs recursively in the original resDirs order, preserve diagnostic

multiple roots.

- Around line 245-278: Update the finally block in the test method `the default
logger writes session lines to stderr, not stdout` to call
`defaultLogService.shutdown()` before restoring System.out and System.err,
ensuring configured compiler and R8 resources are released even if assertions or
configuration fail.
In
`@quickbuild/daemon/src/test/kotlin/org/appdevforall/cotg/quickbuild/daemon/res/Aapt2LinkTest.kt`:
- Around line 131-177: Add a permission-enforcement precondition as the first
statement of both tests, `a compiled dir that cannot be cleared fails the relink
instead of linking stale flat files` and `an uncreatable compiled dir fails the
relink with a message naming the dir`, using the existing or newly added
`permissionBitsEnforced()` helper with JUnit assumptions so they are skipped
when the runner can bypass permission bits.

Android aapt2 compile --dir multiple resource directories same output directory overwrite .flat filename behavior
💡 Result:
When using the aapt2 compile command with the --dir flag, AAPT2 scans the specified directory for Android resources and compiles them into intermediate.flat files, which are saved in the output directory specified by the -o flag [1][2]. Regarding the behavior of multiple resource directories and filename overwriting: 1. Limitation of Multiple --dir Flags: The --dir flag is designed to take a single path argument [3]. While some command-line tools allow multiple instances of a flag to aggregate inputs, the aapt2 compile command generally expects a single resource directory when --dir is used [1][4]. Attempting to provide multiple --dir flags in a single command may result in only the last provided directory being processed, or an error depending on the specific version and invocation method [5]. 2. Filename Generation and Overwriting: AAPT2 generates the names of the resulting.flat files based on the resource directory structure (e.g., res/drawable/icon.png becomes drawable_icon.png.flat) [6]. Because the output filename is deterministic and derived from the resource name and its qualifier, if you have different source directories that contain resources with the exact same name and configuration (e.g., res1/values/strings.xml and res2/values/strings.xml), the compiled.flat files will have identical filenames [6]. If both are directed to the same output directory, the second file will overwrite the first [6]. 3. Recommendation: To combine resources from multiple directories, the recommended approach is to either merge your resource directories before compilation or invoke aapt2 compile separately for each directory, pointing them to different output directories (or the same one if you are certain no name collisions exist), and then pass all resulting.flat files to the aapt2 link phase [1][5]. Using --dir is generally discouraged for large or complex projects because it bypasses the incremental compilation benefits offered by passing individual files directly to the compiler [1][7].

💡 Result:
In aapt2’s older tools/aapt2/compile/Compile.cpp:
-osets the output path.--dir <res-dir>recursively scans an Android resource directory and writes a ZIP archive of compiled resources. It cannot be combined with explicit input files. (android.googlesource.com)- For each resource,
buildIntermediateFilename()constructs:
<resourceDir>[-<qualifiers>]_ <name>[.<extension>].flat
(without the space), e.g.:
layout_main.xml.flat
drawable-hdpi_icon.png.flat
values_strings.arsc.flat
The resource directory and configuration qualifier are extracted from the parent directory; the filename stem and extension come from the input filename. (android.googlesource.com)
In newer AAPT2 code, the same logic is named BuildIntermediateContainerFilename() and handles .9.png specially. (android.googlesource.com)

Isolate each resDir during AAPT2 compilation. resDirs accepts multiple roots, and DaemonService.relink forwards them unchanged. AAPT2 derives .flat names from the resource path, so identical relative resources in two roots overwrite the earlier output. Compile each root into a separate subdirectory and collect .flat files recursively in root order, or reject multiple roots. Add a collision test.

Fixed, with the remedy narrowed to the second option. Per-root subdirectories plus ordered recursive collection is unearned for a case that is unreachable today, so instead the relink fails with a diagnostic when more than one resource root is passed, and extending resDirs() turns red rather than quiet. 9049e9b

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Guard the unreadable-file test against a root test runner.
File.setReadable(false) returns true and clears the permission bits, but a process running as root still reads the file. Many CI containers run tests as root. In that case the second snapshot parses the same source, the fingerprint does not move, and the assertion on Line 40 fails. Confirm the permission actually took effect before asserting.
💚 Proposed change
check(locked.setReadable(false)) { "could not revoke read permission" }
try {
+ // A root test runner ignores the cleared read bit; the scenario is then untestable.
+ assumeTrue(!locked.canRead(), "the test runner can still read the file (root?)")

Not taking it. The named mechanism does not apply here: no workflow in this repo uses a container key, and debug.yml reaches for sudo apt-get, which a root user would not need. More to the point, assumeTrue converts a red failure into a skip, and a skipped test reads as coverage that is not there.

Guard the two permission-based tests against a root test runner.
Both tests depend on POSIX permission bits blocking an operation. A process with CAP_DAC_OVERRIDE, for example root in a CI container, ignores those bits. Then deleteRecursively succeeds and mkdirs succeeds, so the expected diagnostics never appear and both tests fail deterministically.
setWritable(false) still returns true under root, so line 140 and line 164 do not protect against this.
Add a precondition that skips both tests when the permission bit does not actually deny access.
♻️ Proposed guard
+ /**
+ * True when POSIX permission bits actually deny access to this process. A root runner holds
+ * CAP_DAC_OVERRIDE, so a read-only dir stays deletable and writable, and the reset guards
+ * below cannot be exercised.
+ */
+ private fun permissionBitsEnforced(): Boolean {
+ val probe = File(tempDir, "probe").apply { mkdirs() }
+ probe.setWritable(false)
+ val denied = !File(probe, "child").mkdirs()
+ probe.setWritable(true)
+ return denied
+ }Then gate each test, for example with org.junit.jupiter.api.Assumptions.assumeTrue(permissionBitsEnforced()) as the first statement.

Not taking it, same as the JavaSourceAbiEdgeTest finding. No workflow in this repo runs tests in a root container, and assumeTrue would turn a diagnosable red failure into a skip that reads as coverage we do not have.

Review: :quickbuild:daemon (PR 9/11)
Reviewed at aa2f682, against the PR base feature/ADFA-4128-qb-08-core-orchestration. 11 production sources read line by line and cross-checked against :quickbuild:protocol, :quickbuild:core (the client), ClassOpener in PR 10, and the app's JDK discovery. This repo has no written approve/request-changes rule, so the review's default applied; the finding bar is REVIEW.md's.
2 IMPORTANT, 7 MINOR, 2 NITPICK inline, plus 1 unanchored below. Both IMPORTANTs are error-branch defects, not common-path ones, and both have one-line-ish fixes. This is careful, unusually well-documented code - the KDocs carry the why and the reasoning is usually right where a reviewer needs it - and the test suite genuinely pins its own claims (DaemonLoopErrorTest asserts the OOM/StackOverflow arms and that a NoClassDefFoundError still ends the loop, so the exit contract keeps its teeth).
Previous round re-checked (4 CodeRabbit findings)
| Finding | Status | Evidence |
|---|---|---|
Aapt2Link multi-res-root collapse |
fixed | Aapt2Link.kt:123-134 fails the relink naming both roots; read at head, not taken on the reply |
DaemonServiceOpsTest service never shut down |

JavaSourceAbiEdgeTest root test runner |

Nothing regressed and nothing was marked fixed on the strength of a reply.

Finding without a diff anchor
MINOR: the PR description's verified test and coverage numbers are stale as of this head. The body says "[verified 2026-08-21] At this cut: ... 193 tests ... Coverage 97.4% line / 87.9% branch", over "895 lines, 431 branches". Measured at aa2f682 (after the CodeRabbit-fix commit added code and tests): 199 tests, 97.1% line / 83.5% branch, 958 lines / 503 branches. The per-package table drifts too - …daemon.dex reads 95.4% line / 47.4% branch here, not 99.0 / 57.1. The substance holds (0 failures, 0 skipped, comfortably above the bar), but QA reads this table, and "at this cut" now names a different cut. Refresh the numbers or say which commit they were taken at.
Checked and found sound
ProtocolCodec never throws on malformed input and values is Map<String, Any>, so the toString arm cannot NPE; DexTool's stale-dex sweep, split-payload rejection, LinkedHashMap last-root-wins dedup, and the D8DiagnosticsCollector proxy's modifyDiagnosticsLevel/hashCode/equals/toString arms (r8's handler has no primitive-returning method the else arm would mishandle); Aapt2Link's watchdog closing the pipe to release the unbounded drain, and the stableIds-named-but-missing hard failure; lastGoodOutputs/javaAbi deliberately held across failed compiles; deleteJavaOutputs(changedFiles) placed after the pre-snapshot so a vanished nested class surfaces as a deletion.
Two hypotheses I tested and discarded rather than posting:
JavaSourceAbimisses aclass->interfaceconversion. It does not. I ran the fingerprint renderer against javac 21's real parser:modifiers.toString()emitsinterface, so the fingerprints differ. (enumandrecordare not emitted, but constructing a collision needs member-for-member identical bodies.)- An under-reported
changedClassFilesmisroutes the deploy. It cannot today.DeployPolicy.decideis the list's only consumer and reads it solely for anisEmpty()check on a pre-v2 baseline - "the payload is the whole class set either way". This is also whyrebaselinefiring on any single-source module is not worth a finding of its own.
One lead I dropped as unreachable: a DexTool construction failure leaking the just-built IncrementalCompiler out of the Session(...) argument list. File.toURI().toURL() cannot throw for a real file and URLClassLoader's constructor has no failure mode here, so no configure path leaks an engine.

| // it surfaces later as a NoClassDefFoundError from inside d8. | ||

MINOR: building the replacement session mutates the still-installed session's scratch tree, which the comment above does not cover.
The "build the replacement BEFORE releasing the old one" reasoning protects the old session's tool objects, but both sessions share outDir. The replacement's IncrementalCompiler constructor deletes shrunk-classpath-snapshot.bin, recursively deletes ic/, and overwrites cp-snap/<index>-<jar>.snap - all under the live session's workDir. Harmless when the construction succeeds, because the old session never compiles again; but when it throws, the old session survives with its IC caches gone and its per-jar snapshot files a partial mix of two classpaths, so its next compile diffs against snapshots describing neither.
Reachable only via the same constructor failure as the fingerprint finding. Constructing into a fresh scratch subdir and swapping on success closes both.
There was a problem hiding this comment.
Confirmed: the replacement's constructor mutates the live session's tree before the swap. Deferring the fresh-subdir-and-swap restructure to a follow-up; the fingerprint reorder above removes the nastiest consequence (a fingerprint describing snapshots that never got built), and the remaining exposure needs the same constructor failure.
There was a problem hiding this comment.
Deferral accepted - the fingerprint reorder does remove the consequence that mattered, and the fresh-subdir-and-swap restructure is a bigger change than this PR should carry.
Leaving the thread open so the follow-up has somewhere to land; please link the ticket here when it exists.

MINOR: still open at head and at the stack tip, as agreed - flagging it only so it does not get lost.
Re-checked rather than assumed: IncrementalCompiler's init at 419271e8 still calls discardStaleIncrementalState and writes cp-snap/<index>-<jar>.snap under the live session's workDir before the swap in configure, and the tip 8f79f47e changes nothing here. The fingerprint reorder did remove the consequence that mattered, so this stays a deferral rather than a finding in this round.
Please link the follow-up ticket here when it exists, so the thread has somewhere to close to.

MINOR: this is a byte-for-byte duplicate of ClassOpener.stripFinalModifier, which lands in PR 10 of the same stack.
gradle-plugin/src/main/java/com/itsaky/androidide/gradle/quickbuild/ClassOpener.kt:34 has the identical ClassReader/ClassWriter(0)/visit/visitInnerClass body against the same ASM version. This class's KDoc asserts the two match ("matching the proxy app build's ClassOpener in the gradle-plugin"), and the dex verifier invariant depends on it - so a later edit to one and not the other is a silent verifier failure at class load, with the doc still claiming they agree.
REVIEW.md section 7 names this case directly: behaviour reinvented "across a feature that was built in chunks". One owner for the transformation, or an executable check that the two agree.
There was a problem hiding this comment.
Confirmed byte-for-byte. One owner needs a shared-module decision between two separately shipped artifacts, so we are deferring that to a ticket (including an executable parity check); in the meantime the reader-passing change lands in both copies in lockstep.
There was a problem hiding this comment.
Reversing the deferral — we can close this without deciding a shared module. We add a parity test in the daemon that has a test-only dependency on the Gradle plugin, runs the same fixture classes through both FinalStripper.strip and ClassOpener.stripFinalModifier, and asserts the bytes match. A one-sided edit to either then fails the test at build time, which is the guarantee the doc comment was standing in for. The test lands in PR 10 rather than here, since that is where ClassOpener first exists. The single-owning-module refactor can stay a separate, lower-priority cleanup.
There was a problem hiding this comment.
Still open at head. The reply above said the deferral was being reversed with a parity test in the daemon carrying a test-only dependency on the Gradle plugin; 1ea90a63 has neither. quickbuild/daemon/build.gradle.kts declares no dependency on :gradle-plugin, and no parity test exists - the only mentions of ClassOpener under quickbuild/ are three prose references in comments and docs/pipeline.md.
The head commit message itself lists 8 as deferred, so the reply and the commit disagree about what shipped. The bodies are still byte-for-byte identical, and they are now identical in a second way - both took ClassWriter(reader, 0) by hand, in lockstep, which is precisely the maintenance cost an executable parity check exists to remove.
Either land the parity test as described or file the ticket and say so here; leaving the thread claiming a fix that is not in the diff is the part worth avoiding.
There was a problem hiding this comment.
MINOR: withdrawn - the parity test does exist, one PR later in the stack.
My last note said 1ea90a63 had neither the :gradle-plugin test dependency nor the parity test. Both are there at 2656ec96d (PR #1722, qb-10): quickbuild/daemon/build.gradle.kts adds testImplementation(projects.gradlePlugin) with the parity rationale, and FinalStripperClassOpenerParityTest.kt runs four fixture classes - final, open, and a nested pair - through both FinalStripper.strip and ClassOpener.stripFinalModifier and asserts the bytes agree. It is a live @Test, not one of the six @Disabled cases that arrived with that PR (those are all under gradle-plugin/src/test).
Stating its limit as the test itself does, so nobody reads it for more than it pins: both transforms run against the daemon's ASM, so it pins that the two SOURCES still agree when handed one ASM - which is where a one-sided edit shows up - not the bytes each side produces in a real build with its own ASM. That is the guarantee the doc comment was standing in for, so it closes this finding.
Nothing to do in this PR. Resolving.

Review round 2: :quickbuild:daemon (PR 9/11)
Re-reviewed at 1ea90a63, against the PR base feature/ADFA-4128-qb-08-core-orchestration. The delta since round 1 (aa2f682) is 6 production files / ~120 lines, read line by line, plus a re-check of all 11 findings from round 1 against the code at head rather than against the replies.
1 CRITICAL, 1 MINOR, 2 NITPICK new inline, plus 2 round-1 findings still open (replied in their own threads) and 1 unanchored below. Eight of eleven round-1 findings are genuinely fixed and their threads are resolved. The CRITICAL is in the argfile that closed round-1 finding 9: the fix is right about ARG_MAX and wrong about whitespace, and I verified both halves against the real aapt2 binary rather than by reading.
Round 1 re-checked (11 findings)
| # | Finding | Status | Evidence at head |
|---|---|---|---|
| 1 | classpath fingerprint committed before its snapshots | fixed | discardStaleIncrementalState returns the fingerprint, init writes it last. The new test is genuinely red without the fix: Files.createDirectories(snapshotDir) throws after the discard call, where the old code had already written |
| 2 | javac pins no bytecode target | fixed | --release + the now-internal JVM_TARGET; no -source/-target/-bootclasspath present to conflict with it. See the test comment inline |
| 3 | replacement session mutates the live session's scratch | open, deferred | DaemonService.kt:99-113 unchanged; deferral accepted, thread left open |
| 4 | ClassWriter(0) discards copy-through |
fixed | ClassWriter(reader, 0); qb-10's ClassOpener.stripFinalModifier carries the identical change, checked on that branch |
| 5 | -nowarn vs Result.Success.warnings KDoc |
fixed | dead mapping deleted, suppression stated at the flag and on the property |
| 6 | unresolvable-stem skip fails open | NOT fixed | the log is inert in production - replied in thread |
| 7 | unbounded aapt2 diagnostics | fixed | MAX_DIAGNOSTICS = 50 + capped(); the test pins 51 entries ending in a +10 more marker |
| 8 | FinalStripper duplicates ClassOpener |
NOT fixed | the promised parity test is absent - replied in thread |
| 9 | a large baseline pushes argv toward ARG_MAX |
delivered | the argfile landed; it carries the CRITICAL, filed as its own thread |
| 10 | shutdown() skipped on the fatal-rethrow path |
fixed | try/finally around serve |
| 11 | lastJavaAbiChange never surfaced |
fixed | logged in the compile-ok line; the field is reset at the top of kotlinFilesToCompile, so the log cannot carry a stale set from a previous compile |
Nothing was marked fixed on the strength of a reply. Two replies and the head commit message disagree with the code: the 09-01 07:02 UTC reply on finding 8 said the parity test was being added, and the head commit (07:12 UTC) lists 8 as deferred and contains neither the test nor the test-only dependency; conversely that same commit message lists 9 as deferred while the argfile is in the diff.

The identical change in gradle-plugin's ClassOpener lands on qb-10 in lockstep. - Aapt2Link caps parsed diagnostics at 50 plus a "+K more" marker, mirroring DexTool's output-bounding rationale. - The -nowarn asymmetry (kotlinc warnings suppressed, javac's kept) is now stated at the flag, on Result.Success.warnings, and the dead logger.warnings mapping is gone. - deleteJavaOutputs logs the unresolvable-stem skip instead of silently not sweeping stale outputs. - DaemonMain shuts the service down in a finally, covering the fatal-rethrow exit path. - DaemonService's compile-ok log line reports lastJavaAbiChange when non-empty, delivering that field's documented purpose.

Akash's 2 September round, led by the argfile break he verified against build-tools 37.0.0. - A link whose resource paths contain whitespace keeps the inline -R pairs whatever the input count. The argfile format splits on whitespace and has no escape for it, so one space truncated that input and every later one - and the project directory reaches these paths unsanitised, with "My Application" the default new-project name. Pinned by a test that fails without the guard. #1721 (comment) - The inline path deletes a link-inputs.txt an earlier link left behind, which nothing else swept. #1721 (comment) - The unswept-output warning reaches the daemon log. It went to compileLog, which defaults to a no-op and which DaemonService cannot pass without also taking kotlinc's verbose channel, so the warning has its own parameter. #1721 (comment) - javac's options are assembled by an internal function and --release is asserted on the argv. The host JDK emits the same class file version either way, so no compile-and-read test can fail when the flag is dropped. #1721 (comment) - CollectingLogger's KDoc no longer says the result is built from warnings as well as errors; -nowarn means no real compile drives that channel. #1721 (comment) Not fixed here: the FinalStripper/ClassOpener parity test and the DaemonService reconfigure-mutates-the-live-session deferral. Both are ticket-only follow-ups; the ticket text is drafted with this round's replies.

Round 3 on 9/11. Reviewed at 419271e8e439666cbdb561fa419ef1f90a235082, every finding re-checked against the stack tip 8f79f47e37fe - the only head-to-tip change in this module is the FinalStripper parity test, so all twelve inline findings below are live at the tip. Reachability was settled against the trees that actually hold the callers (3231a6b7 for the gradle-plugin, 8f79f47e for the app wiring) rather than from this SHA alone, and each finding names the tree that settled it. That is also why the trust boundary is not raised as a finding: the daemon speaks only stdin/stdout to a same-UID child spawned as java -jar with no shell and a cleared environment (DaemonProcessClient.kt:143-157), its scratch and jar live under noBackupFilesDir, and there is no setReadable/chmod/external-storage call anywhere in quickbuild/ or gradle-plugin/ outside tests - the only cross-UID channel in the feature is the proxy app's bindService into CoGo (QuickBuildHostService, exported, added back in PR #1717), whose uid gate I verified rather than took on trust: all three AIDL methods call enforceCaller first, and it compares Binder.getCallingUid() against the proxy app's PackageManager uid and fails closed when no session is live. This PR touches none of it.
COMPUTED VERDICT: REQUEST_CHANGES - three confirmed IMPORTANT findings. REVIEW.md self-describes as "a coaching doc, not a gate" and carries no approve/request-changes rule, and neither does CONTRIBUTING.md, so the default applied: any confirmed CRITICAL or IMPORTANT blocks; MINOR and NITPICK do not. Severity counts: 0 CRITICAL, 3 IMPORTANT, 4 MINOR, 5 NITPICK, all CONFIRMED. Two of the three IMPORTANTs are new consequences of this round's own fixes, which is the pattern worth naming: each fix landed, and two of them moved the defect rather than closing it.
Previous rounds, re-checked against the code at head rather than against the replies:
- IMPORTANT classpath fingerprint written before its snapshots (
IncrementalCompiler.kt:209) - FIXED at1ea90a63, re-confirmed at head:initwrites it as its last statement. - IMPORTANT javac pins no bytecode target (
JavaCompileStep.kt:58) - FIXED at1ea90a63for the bytecode level. The platform-API half of that thread's verification note does not hold; that is the finding onJavaCompileStep.kt:93. - MINOR replacement session mutates the live session's scratch tree (
DaemonService.kt:99) - still open at head and at the tip, by agreed deferral. Please link the follow-up ticket in that thread. - MINOR

lastJavaAbiChangenever logged (IncrementalCompiler.kt:134) - FIXED at1ea90a63. Its verification note claims the reset "runs on every compile"; it does not - seeIncrementalCompiler.kt:537. - NITPICK
CollectingLoggerKDoc (IncrementalCompiler.kt:668) and NITPICKlink-inputs.txtoutlives its link (Aapt2Link.kt:277) - both FIXED at419271e8. - The four CodeRabbit threads are all answered: two fixed (per-root
.flatcollision, now a loud failure on more than one res root; the test-service shutdown, fixed wider than filed) and two declined with a reason I agree with (assumeTruefor a root test runner turns a red failure into a skip that reads as coverage).
No finding was left without a diff anchor, so nothing is restated here. What was not run: no Gradle build and no on-device check - the PR's own :quickbuild:daemon:test numbers (193 tests, 97.4% line / 87.9% branch) are taken as reported, and every claim above is reasoned from source. Happy to move the ticket to QA once the three IMPORTANTs are settled.

There was a problem hiding this comment.
IMPORTANT: the whitespace fallback disables the argfile for exactly the projects it was added to protect.
resourceInputs.any(::hasWhitespace) is ORed with the count check, so one space anywhere sends every input back to inline -R pairs whatever the count. Settled against the trees that have the callers: the default new project is My Application (templates-api/.../parameters.kt:445 at 8f79f47e, project dir File(saveLocation.value, projectName.value) at base.kt:128, unsanitised), and collectLibraryResourcePaths() (QuickBuildTasks.kt:827 at 3231a6b7, PR #1722) emits absolute merged_res and dependency-flat paths from under it. So for a default-named Material/AndroidX app the argfile branch is dead and the link runs with the same few-thousand-pair argv ARGFILE_THRESHOLD exists to avoid. The new test asserts that shape: 105 inline -R pairs for a My Application path.
Nothing measures either side - not the real flat count, and not the exec argument budget. Linux derives that from RLIMIT_STACK/4, about 2 MB on Android's 8 MB default, which a few thousand ~130-byte paths would not cross. So the shipped state is either a mechanism that is never needed or a default project left unprotected, and no evidence in the PR says which.
Stage whitespace-free symlinks to the inputs under workDir and list those, so one path shape serves every project; or measure a corpus app's flat count against the device budget and record the number here.

There was a problem hiding this comment.
IMPORTANT: the Kotlin compile is the only tool path in this module whose diagnostics are unbounded, and the callers through the stack tip amplify rather than cap it.
CollectingLogger.errors accumulates every kotlinc error line, this map is 1:1 over it, Result.Failed carries all of them, and DaemonService.compile puts them in the response. Delete a dependency from build.gradle and save: kotlinc emits one unresolved-reference error per use site - hundreds to thousands in a real app.
Traced to the tip, where nothing narrows it. On the single-threaded session dispatcher: DaemonProcessClient.kt:548 maps every element to a BuildDiagnostic, LiveReloadOrchestrator.kt:769 retains the whole list in lastCompileDiagnostics for the session, and :750 compares it whole for structural equality on each later failed build - so the cost there is a stalled session, not a UI stall. The UI-facing half is QuickBuildOutputLines.kt:361, which expands the list into one Build Output line per diagnostic, and QuickBuildSessionState.kt:156, which holds it as observed state.
Both siblings in this same PR are capped for exactly this reason - DexTool.MAX_DIAGNOSTIC_CHARS at 4000 and Aapt2Link.MAX_DIAGNOSTICS at 50, the latter added this round on the argument that "the whole list rides a protocol line into a phone-screen panel". javac's half is bounded by its own 100-error default. This is the sibling that round missed, and the most frequently exercised of the three.
Cap this list the way Aapt2Link.capped() does, with the same "+K more elided" marker.

There was a problem hiding this comment.
IMPORTANT: --release 17 pins the platform API surface to the host JDK's, not to the project's android.jar, so the Java pass accepts sources the standard build rejects.
Under --release, javac resolves java.* from the JDK's own ct.sym signatures. android.jar reaches this compile only through -classpath (DaemonService.configure line 85), and the platform shadows it. A .java source calling a JVM-only API - ProcessHandle.current(), which this module's own DaemonMain.kt:38 uses, or Collectors.teeing - compiles green here and is rejected by AGP's JavaCompile, which puts android.jar on the bootstrap classpath. If Quick Build deploys first, the device throws NoClassDefFoundError against a green build.
The comment above says the opposite ("java.* resolves against ... release-17 signatures" is the fix, but release-17 is not the project's compileSdk), and the resolved thread on this flag records that it "pins both halves - bytecode level and platform API surface". Only the bytecode level holds. The Kotlin pass is not affected: the standard build's kotlinc is equally permissive here.
Pass -bootclasspath <androidJar> with -source/-target from JVM_TARGET instead of --release, matching what the standard build does to javac.

MINOR: a classpath entry that is a directory is fingerprinted without its content, so an in-place change to one keeps this guard silent.
if (jar.isFile) contentCrc(jar) else -1L means a directory entry contributes only path|File.length()|-1, and length() on a directory is a filesystem constant. Rewrite a class inside such an entry and the fingerprint still matches, so discardStaleIncrementalState keeps ic/ and the shrunk snapshot, and compileKotlin then asserts assureNoClasspathSnapshotsChanges(true) over a classpath that genuinely moved - the "stale dependents ship silently, the worst silent failure this feature has" case this function's own KDoc names.
Reachability, as far as I can take it: the only production producer is QuickBuildPlugin.kt:295 at 8f79f47e, variant.compileClasspath.elements, and a library sibling module is an expected project shape (quickbuild/README.md:117 discusses "the user's own library modules in a multi-module project"). Whether AGP hands this task a classes directory or a jar for such a module is the one thing I could not settle from source - it needs a real resolution, which you can run and I cannot. Graded MINOR on that uncertainty; if a directory does appear, the consequence above makes it IMPORTANT.
Fold each file's path, size and CRC into the fingerprint for a directory entry, or fail configure on a non-file classpath entry - which also makes the answer visible instead of silent.

MINOR: this completeness check compares a path-keyed map against the raw input list, so one repeated path makes every later compile a full Kotlin recompile.
byPath and result are both keyed by absolute path, but the size is compared to javaSources.size. Hand the same .java twice - or once as /a/B.java and once as /a/./B.java - and result.size is permanently one short, so snapshot() returns null on every compile, kotlinFilesToCompile takes the current == null arm, and every save silently recompiles the whole module with nothing saying why. That is the feature's headline claim quietly inverted, and no diagnostic separates it from a slow device.
Unreachable through the stack tip: the sole production caller is LiveReloadExecutorImpl.kt:368 at 8f79f47e, which sources the list from QuickBuildProjectLayout.allSources() (:48-57) - that normalises each root with absoluteFile.normalize(), .distinct()s the roots and .distinct()s the walked files, so no duplicate path reaches the daemon.
Compare against byPath.size.

NITPICK: this early return skips the only reset of lastJavaAbiChange, so the compile-ok log can carry a previous compile's set.
kotlinFilesToCompile clears the field as its first statement, but it is never reached when there are no Kotlin sources, and DaemonService.compile reads the field to build the javaAbiChange= tail of the ok line. A session that compiles Kotlin and then a source set with none logs the older set beside this compile's counts - the opposite of what that line exists for. It also contradicts the verification note on the resolved thread for this field, which says the reset "runs on every compile".
Reset lastJavaAbiChange here too, or move the reset up into compile() where it cannot be bypassed.

NITPICK: the read itself sits outside the backstop whose comment says it covers a pathological line.
The try below wraps parse and encode, and its comment explains that as protection against "a pathological line, or a response carrying a compile's whole changed-class list". But readLine() is the call that actually allocates the line, so an OutOfMemoryError from it escapes serve and exits the JVM - the very input the comment names is the one case the guard misses. Only CoGo writes this pipe, so no request reaches that size today; what is wrong is the comment's claim about its own scope.
Move the read inside the try, or narrow the comment to parse and encode.

There was a problem hiding this comment.
NITPICK: a blank stableIds is treated as a supplied path here, unlike the tool paths in configure.
configure filters aapt2/d8Jar/androidJar with isNullOrBlank(), but request.stableIds?.let(::File) turns "stableIds": "" into File(""), whose isFile is false - so Aapt2Link.relink hard-fails with stable-ids file is missing: <daemon cwd>, naming a directory the user never configured. Nothing sends a blank through the stack tip: DaemonProcessClient.relink (:313 at 8f79f47e) emits the key only inside inputs.stableIdsFile?.let { ... }. The asymmetry is what a second client would trip on.
Blank-normalise with takeUnless { it.isBlank() }, matching configure.

There was a problem hiding this comment.
NITPICK: the timeout flag is read without checking that the kill hit a live process, so a link that finished can be reported as timed out.
Not a visibility bug - timedOut is an AtomicBoolean and the two threads are correctly ordered. The defect is the decision logic. The aapt2-watchdog daemon thread WRITES the flag whenever process.waitFor(timeoutMillis, ...) returns false, without checking whether the process was still alive; destroyForcibly() then no-ops on one that already exited. The daemon's request-loop thread READS it here, after it has already drained the full output and taken a real exit code - and still returns ProcessResult(-1, "aapt2 timed out ..."), failing a relink that succeeded. A two-minute boundary makes it rare rather than impossible, and a rare spurious relink failure is the hardest kind to diagnose from a bug report.
Set the flag only when process.isAlive held before destroyForcibly(), or prefer the observed exit code when the drain completed.

There was a problem hiding this comment.
NITPICK: this module ships without the README both its siblings have.
:quickbuild:core and :quickbuild:protocol each carry a module README.md (core adds one per domain package), and quickbuild/README.md holds the shared terms - but quickbuild/daemon has none, so the exit contract, the session warm-state lifecycle and the two-pass Kotlin/Java compile are documented only in KDoc spread across eleven files. REVIEW.md's docs checklist item and CLAUDE.md's "keep docs in step with code" both point at the module README as the place for that.
Add quickbuild/daemon/README.md covering the protocol loop, the session lifecycle and the two-pass compile.

Three IMPORTANT findings, all live at the stack tip. Two of them are new consequences of this round's own fixes: the argfile whitespace fallback leaves the default-named project on the unprotected inline path, and the resolved --release thread's platform-API claim does not hold - javac still resolves java.* against the host JDK rather than the project's android.jar. The third is the kotlinc diagnostics list, the one tool path in this module still uncapped after the aapt2 cap landed. The MINORs and NITPICKs do not block.

Part 9/11 of the stacked split of #1669 (requested by Akash). Base: feature/ADFA-4128-qb-08-core-orchestration. Stack overview + review mechanics: PR 1 (#1713). Terms are defined in quickbuild/README.md (lands in PR 1).
This is where the speed comes from: keeping a compiler warm between edits, so a save costs seconds instead of a full cold build.
