ADFA-4934: Install a .cgp or .cgt file opened from outside the app

[davidschachterADFA]

Summary

Opening a .cgp (plugin) or .cgt (template collection) file from outside CoGo — e.g. an email attachment — now prompts to install it, instead of doing nothing (ADFA-4934).

• New ExternalFileInstallActivity with a VIEW intent-filter for .cgp/.cgt (both content:// and file://, typed and untyped — see manifest comments for why each variant is needed).
• .cgp files are copied to a temp file and forwarded into the existing PluginManagerActivity install flow (conflict/signature-check, overwrite confirmation) — reused verbatim, no new plugin UI.
• .cgt files get a new TemplateCollectionRepository, since no import/conflict backend existed for template collections before: validates the archive via the existing ZipTemplateReader, and on a filename collision offers overwrite / rename & install / ignore, using the archive's filename as its identity (templates.json has no collection-level name field).
• The .cgt install/conflict/rename dialogs are built in Jetpack Compose per ADR 0009 (caught by an architecture-review pass before opening this PR) — first Compose UI in the app module itself, reusing floating-window's FloatingTheme for visual consistency with the IDE's XML theme.
• Mechanical prep: introduced a shared PLUGIN_ARCHIVE_EXTENSION constant, replacing ~7 duplicated .cgp string literals.

Test plan

• :app:testV8DebugUnitTest — full suite passes, including 18 new tests (ExternalFileInstallViewModelTest, TemplateCollectionRepositoryImplTest)
• :app:assembleV8Debug builds and installs cleanly
• Verified end-to-end on a physical arm64 device (Galaxy Note20 Ultra, Android 13):
  • "Open with" chooser correctly lists Code on the Go for both .cgp and .cgt
  • Fresh .cgt install → confirm dialog shows filename + parsed template names → installs, template picker sees it without restart
  • Colliding .cgt → all three paths (Overwrite / Rename & Install / Ignore) verified
  • .cgp → forwards into Plugin Manager's existing install dialog; invalid file correctly rejected with no crash and no broken entry
  • No crashes anywhere in logcat across the session

Two things were found and fixed during on-device testing (not caught by unit tests or a clean build):

1. A rendezvous effect channel could silently drop the first UI effect on a fast synchronous path — switched to a buffered channel.
2. dumpsys package showed a mimeType on any <data> tag applies to the whole <intent-filter>, not just that tag, breaking untyped file:// matching — split into dedicated typed/untyped filters (see manifest comments).

📝 Walkthrough

• Added support for installing external .cgp plugin and .cgt template collection files.
• Added typed and untyped content:// and file:// intent filters for lowercase and uppercase extensions.
• Added .cgt validation, conflict detection, overwrite, rename, ignore, retry, and cleanup flows.
• Added Compose dialogs using FloatingTheme.
• Added path-traversal protection, safe staging, failed-write preservation, and rename fallback handling.
• Improved cold-start, process-recreation, duplicate-event, cancellation, and temporary-file cleanup handling.
• Added shared archive-extension and FileProvider utilities.
• Added regression tests for installation safeguards, URI handling, collisions, cleanup, and retry behavior.
• Builds and physical-device verification completed successfully.
• Known limitation: Filename-less content:// URIs cannot match manifest filters.
• Risk: The exported activity processes external file intents. URI validation and temporary-file cleanup must remain correct.
• Risk: Confirmed overwrite replaces an existing template archive. The reserved core archive remains protected.

Walkthrough

The change adds external .cgp and .cgt installation through exported intents and Compose UI. It adds template collection storage, source-aware plugin cleanup, shared FileProvider utilities, archive-extension centralization, flashbar support, and Robolectric coverage.

Changes

External Archive Installation

Layer / File(s)	Summary
Shared archive extension composite-builds/.../constants.kt, app/src/main/java/.../actions/file/*, app/src/main/java/.../handlers/*, app/src/main/java/.../repositories/*, plugin-manager/.../PluginManager.kt	The shared archive extensions replace hardcoded plugin checks across discovery, validation, installation, editor handling, and file actions.
Template collection repository app/src/main/java/.../repositories/TemplateCollectionRepository*.kt, app/src/test/java/.../repositories/TemplateCollectionRepositoryImplTest.kt	The repository inspects archives, detects collisions, validates names and paths, installs collections, reloads templates, and reports feature availability.
External archive intake and UI app/build.gradle.kts, app/src/main/AndroidManifest.xml, app/src/main/java/.../activities/ExternalFileInstall*.kt, app/src/main/java/.../viewmodels/ExternalFileInstallViewModel.kt, resources/src/main/res/values/strings.xml	The exported activity accepts archive intents. The ViewModel validates and stages files. The Compose screen handles confirmation, conflict, rename, retry, success, and error states.
Source-aware plugin installation app/src/main/java/.../ui/models/PluginManagerUiState.kt, app/src/main/java/.../viewmodels/PluginManagerViewModel.kt, app/src/main/java/.../activities/PluginManagerActivity.kt, ARCHITECTURE.md	Plugin installation distinguishes content URIs from local files, suppresses duplicate forwarded dialogs, and applies source cleanup across installation outcomes.
Shared FileProvider routing common/src/main/java/.../FileProviderUtils.kt, app/src/main/java/.../dnd/*, app/src/main/java/.../utils/{ApkInstaller,IntentUtils}.kt, common/src/main/java/.../{FeedbackEmailHandler,FeedbackManager}.kt	FileProvider authority and URI creation move to shared context utilities used by drag-and-drop, installers, intent helpers, and feedback attachments.
Flashbar synchronization and support common/src/main/java/.../Flashbar{Activity,}Utils.kt	Flashbar success and error helpers can await display completion with a bounded timeout and foreground-activity handling.
Validation coverage app/src/test/java/.../viewmodels/ExternalFileInstallViewModelTest.kt, app/src/test/java/.../repositories/TemplateCollectionRepositoryImplTest.kt, common/src/test/java/.../utils/FileProviderUtilsTest.kt	Tests cover archive validation, feature availability, forwarding, conflicts, retries, cleanup, sanitization, unique-name generation, repository safety, and FileProvider authority generation.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk:🟠 High · up to 8bfe6

The new external archive installation flow still has unsafe overwrite, cancellation, retry, and request-lifecycle paths that can lose template collections, bypass conflict handling, or disrupt an active install. Merge should be blocked until these correctness and data-preservation issues are addressed.

A rabbit brings an archive bright,
Through Compose screens and dialogs light.
Plugins hop through guarded doors,
Templates settle on new shores.
URIs share one trusted lane—
Cleaned up neatly after rain.

Preserve coroutine cancellation and use the project logger.

The repository's runCatching blocks convert CancellationException into Result.failure, so normal coroutine cancellation can be reported as an install or validation failure. Rethrow CancellationException and catch only expected validation or I/O failures. Replace android.util.Log in this repository and ExternalFileInstallViewModel with SLF4J LoggerFactory and parameterized messages.

Ran /code-review on this PR and fixed everything it found (2 more commits):

Real correctness bugs:

• "Delete installation file after install" silently did nothing for a .cgp forwarded from ExternalFileInstallActivity — DocumentsContract.deleteDocument() only works against a real SAF DocumentsProvider; our own IDEFileProvider isn't one, so it returned true unconditionally without deleting anything. Now dispatches to contentResolver.delete() for our own authority (verified via decompiling FileProvider.class) and no longer even shows the checkbox for forwarded installs — there's no source worth optionally keeping.
• Cold-start race: isPluginManagerAvailable()/isTemplatesFeatureAvailable() could run before IDEApplication's async setup finished if the OS cold-started straight into the trampoline activity. Now polled briefly instead of failing on the first check.
• Two process-death drops (ExternalFileInstallActivity and PluginManagerActivity both gated on savedInstanceState == null, which is wrong for exactly the recreation case that most needs to reprocess). Replaced with per-ViewModel-instance idempotency.
• installCollection()'s collision check was case-sensitive, bypassing findExistingCollision()'s case-insensitive matching.
• A failed template install used to delete the temp file and close the screen, forcing a full re-open of the original attachment to retry. Now the dialog stays open and just shows an error.
• Rename dialog: an async name suggestion could clobber in-progress user input.
• ShowTemplateNameConflict.info was computed but silently dropped instead of shown.

Manifest gaps:

• .CGP/.CGT (uppercase) never matched — pathPattern has no case-insensitive mode. Added uppercase variants and consolidated 6 filters down to 3.
• Documented (as an explicit, accepted limitation) that a sender whose content:// Uri never carries the filename in its path — some email providers' attachment Uris look like this — can't match regardless; the alternative (a pathPattern-less mimeType="*/*" filter) would register this app for every file-view intent on the device, which is worse.

ADR 0009 violation, fixed before any of the above: the three new .cgt dialogs were MaterialAlertDialogBuilder (View-based); ADR 0009 requires new dialogs to be Compose. Rebuilt them as composables, reusing floating-window's FloatingTheme.

One regression caught by re-testing on-device after the review fixes:installCollection() tried File.renameTo() as an "atomic move" — this silently fails on the test device even within the app's own private storage (a known Android renameTo() unreliability), so template installs would have always failed. Fixed with a copy+delete fallback.

Re-verified the full flow on a physical device after every fix: fresh install, rename, overwrite, retry-after-failure, and the delete-checkbox's absence for forwarded installs.

Rethrow coroutine cancellation.

runCatching captures CancellationException in both repository operations. A canceled caller can receive a failure Result instead of cancellation.

Catch CancellationException explicitly and rethrow it. Catch only expected recoverable I/O and archive parsing failures for the Result path.

As per coding guidelines: “In coroutine code, catch exceptions inside the launching coroutine, rethrow CancellationException, and avoid broad catches where narrower types suffice.” Based on learnings: “prefer narrow exception handling that catches only the specific exception type reported in crashes ... instead of a broad catch-all.”

Use the shared plugin archive extension.

The .cgp literals duplicate the archive-extension contract. Build this suffix from PLUGIN_ARCHIVE_EXTENSION so intake, validation, and temporary-file handling cannot diverge.

As per coding guidelines: “Reuse existing helpers, extract duplicated logic, replace repeated magic values with named constants, and maintain loose coupling with one owner per concern.”

Match the archive extension case-insensitively.

findCollisionFile filters with file.extension == TEMPLATE_ARCHIVE_EXTENSION. This comparison is case-sensitive. The base-name comparison on the next line is case-insensitive, so the two checks disagree. The manifest accepts uppercase .CGT files, so a stored MyTemplates.CGT is not detected as a collision and a second, case-differing collection can be created.

🐛 Proposed fix

 templatesDir
- .listFiles { file -> file.extension == TEMPLATE_ARCHIVE_EXTENSION }+ .listFiles { file -> file.extension.equals(TEMPLATE_ARCHIVE_EXTENSION, ignoreCase = true) }
?.firstOrNull { it.nameWithoutExtension.equals(baseName, ignoreCase = true) }

Announce the long-press help action to accessibility services.

combinedClickable receives an empty onClick and no labels. Two effects follow. First, the element becomes a focusable click target that performs no action. Second, screen readers cannot discover the long-press help action, because onLongClickLabel is not set.

Pass an onLongClickLabel from a cd_* string resource that describes the action. If the tooltip is the only action, keep the empty onClick but label the long press.

As per coding guidelines: "Content descriptions must use cd_* string resources, describe the action rather than the icon, and be state-aware for toggles."

Addressed the remaining CodeRabbit findings in f896c47:

Fixed:

• Path traversal via targetBaseName in TemplateCollectionRepositoryImpl.installCollection (reject separators/./.., plus a canonical-path containment check).
• Data-loss risk on overwrite: the incoming archive is now staged fully under templatesDir before the existing file is deleted.
• PluginManagerViewModel.installPlugin no longer converts cancellation into an install-failure toast; cleanup runs under NonCancellable.
• Switched the two new files' logging to SLF4J (ExternalFileInstallViewModel, TemplateCollectionRepositoryImpl), per REVIEW.md.
• Added FileProviderUtilsTest, path-traversal + preserve-existing-on-failure tests, and switched ExternalFileInstallViewModelTest to use tempFolder.root.

Dismissed (with reasoning in-thread):

• "Hostless file:// URIs are rejected by host=\"*\"" - verified on-device this is incorrect for the standard file:///path form (empty-string authority, not null); pm query-activities resolves ExternalFileInstallActivity as isDefault=true for exactly that URI shape.

Already fixed by earlier commits on this branch (confirmed against current code, marked resolved): long-press tooltips on the three dialogs, and CancellationException rethrow in findExistingCollision.

Verification: full relevant unit test suite green (ExternalFileInstallViewModelTest, TemplateCollectionRepositoryImplTest, FileProviderUtilsTest), plus a fresh on-device regression pass on the .cgt install/overwrite/rename flows on the physical Note20 Ultra (no stray .tmp/temp files left behind in any path).

Included review availability: Your plan includes up to 2 reviews per rolling hour; 0 remain after this review.

Ran a max-effort /code-review pass over the whole PR and fixed everything it found (commit 6fbf4c1):

Data-loss / security fixes:

• PluginRepositoryImpl: case-sensitive .cgp check could permanently delete an uppercase-named plugin file - now case-insensitive.
• PluginManagerViewModel: the same-ID signature check could be skipped if Install was tapped before the async plugin list finished its first load - now awaits that load first.
• PluginManagerViewModel: declining an overwrite, or a failed install, no longer deletes a user-picked file (only our own disposable forwarded-temp copies are ever cleaned up before a success) - matches the "delete after install" checkbox's actual meaning.
• TemplateCollectionRepositoryImpl: replaced delete-then-write with a backup-swap-restore, so a failed final copy can no longer destroy the existing collection; staging/backup filenames are now unique per call so concurrent installs of the same collection can't race on the same path.

Other correctness fixes:

• PluginManagerActivity: both install dialogs route back-press/tap-outside through the same cancel path as their buttons, so a "silently cancelable" dialog can no longer leak a forwarded temp file.
• AndroidManifest.xml: added keyboard|keyboardHidden|navigation to both install-flow activities' configChanges - closes the same class of bug (a config change silently dropping the forwarded-install dialog) for another axis.
• ExternalFileInstallScreen.kt: all three dialogs now disable dismiss/cancel while an install is in flight, so a fast tap can't race a file delete against the in-progress install.
• TemplateProviderImpl: template directory scan is now case-insensitive, matching the repository's already-case-insensitive install/collision logic (an uppercase .CGT collection could previously install successfully but never actually appear in the template list).
• Replaced a blind 300ms delay before finishing ExternalFileInstallActivity with a real Flashbar "entrance animation finished" signal (new flashSuccessAwaitShown/flashErrorAwaitShown in common), and widened the IDE-setup-wait budget from ~2.7s to ~8s to better match a real cold start.

Deferred, with reasoning:TemplateProviderImpl's per-archive parse failures are still only logged, not surfaced back to installCollection's caller. Properly closing that needs exposing per-archive load state across the templates-api/templates-impl module boundary - a larger change than proportionate for how speculative that specific failure mode is. Flagging rather than silently skipping.

Verification: full relevant unit test suite green, spotlessApply clean, a self-run architecture-review pass (0 violations against ARCHITECTURE.md/ADRs), and a fresh on-device regression pass on the .cgt install/overwrite flow on the physical Note20 Ultra (no crashes, no stray temp/backup files).

Ran a follow-up /code-review high pass and fixed what it found (commit 0d899a7):

• TemplateCollectionRepositoryImpl: a failed backup restore (after an already-failed swap) was silently discarding its return value - now logged loudly instead of leaving the user's original collection invisible under a .bak filename. Also stopped a ITemplateProvider reload failure from reporting the whole install as failed when the actual file swap had already succeeded (that was leaving destFile installed on disk while the caller believed nothing happened and would hit a spurious "already exists" on retry).
• ExternalFileInstallViewModel.suggestUniqueBaseName: capped its search loop so a pathological repository can't hang the Rename dialog forever.
• New InstallTempFiles util: extracted the near-identical filesDir/temp staging code duplicated between ExternalFileInstallViewModel and PluginManagerViewModel's ContentUri branch, and added an hour-old-orphan sweep - covers a temp file being left behind forever if a forwarded .cgp's hand-off to PluginManagerActivity never completes (e.g. process death mid-handoff).
• FlashbarActivityUtils: extracted a shared configureFlashbar() so showFlashBar()/showFlashBarAwaitShown() (added earlier this PR) can't silently diverge in their builder setup - confirmed duplication from the previous round.

Documented rather than fixed (with reasoning in the manifest comments): a mixed-case .cgp/.cgt extension (e.g. Plugin.Cgp) won't match android:pathPattern's lowercase/UPPERCASE-only variants - full case-permutation enumeration would bloat the manifest disproportionately for how rare a genuinely mixed-case sender is; and suppressing Activity recreation for dialog continuity (uiMode/locale/etc.) means already-inflated View content can look stale until back-and-return - a pre-existing, already-accepted tradeoff this PR only extended to more config axes, not introduced.

Verified: relevant unit tests green (plus a new test for the suggestion-cap), spotlessApply clean.

Another /code-review high pass, fixed what it found (commit 65c7003):

The headline bug: this PR introduces .cgt as a new installable archive type, but two pre-existing archive-extension allowlists elsewhere in the app were never updated to include it:

• CodeEditorView's ARCHIVE_EXTENSIONS - opening a .cgt from the file tree would have edited its raw zip bytes as text, silently corrupting the archive on save.
• FileTreeActionHandler's archive exemption - a .cgt over 10MB would get blocked by the "File is too big!" guard that every other archive type is exempt from.

Both fixed by adding TEMPLATE_ARCHIVE_EXTENSION alongside the existing PLUGIN_ARCHIVE_EXTENSION entries.

Other fixes:

• ExternalFileInstallActivity: added singleTask + onNewIntent, closing a race where rapidly double-tapping the same external file could spin up two Activity/ViewModel instances - each minting an independent temp file that PluginManagerViewModel's path-based dedup guard couldn't recognize as the same source, risking two stacked install dialogs / concurrent installs. Verified on-device: a duplicate launch now hits the existing instance ("intent has been delivered to currently running top-most instance") and shows a single dialog.
• PluginManagerActivity: checks the forwarded temp file still exists before showing its install-confirmation dialog (it could have been removed by InstallTempFiles' stale-file sweep from a couple commits ago); also merged the forced/normal install-dialog code paths into one builder so a future change can't be applied to only one branch.
• PluginManagerViewModel: a cancelled install now cleans up its forwarded temp file too (previously only success/failure did), and deleteSourceDocument() no longer swallows CancellationException.

Not fixed, judged out of proportion:ITemplateProvider.reload() re-parsing every installed collection on each install (pre-existing architecture, not a regression), suggestUniqueBaseName's per-iteration directory scan (already bounded to 50 by the previous round's cap, and templates directories are realistically small), and a suggested cross-file "ArchiveType" abstraction spanning 6 files (the two concrete bugs it would have prevented are now fixed directly; the broader refactor is a separate, larger change).

Verified: unit tests green, spotlessApply clean, and an on-device regression pass specifically targeting the singleTask fix (confirmed via dumpsys activity + a clean single-dialog screenshot) plus a .cgt install/cleanup re-check.

One more /code-review high pass turned up a genuine regression from my own previous fix - fixed now (commit 007ce66):

The regression: the singleTask fix from the last round (collapsing a duplicate VIEW intent into one Activity instance) traded one bug for a related one. My first attempt cleaned up the previous pending file at the start of a new onReceived() call - but two onReceived() calls run as independent coroutines with no guarantee the first one finishes (and registers its pending file) before the second one starts its own cleanup check. Verified on-device: sending two different .cgt files in quick succession left both temp files on disk instead of cleaning up the superseded one.

The fix: a generation counter, assigned synchronously (not inside the launched coroutine) so it always reflects real intent-arrival order. Each request checks, right before committing to show its dialog, whether it's still the current generation - if a newer request has since arrived, it abandons itself (and cleans up its own temp file) instead of emitting a stale effect. Re-verified on-device: now exactly one temp file remains, matching whichever file's dialog is actually showing.

Also fixed:

• A narrower version of the same class of bug in PluginManagerViewModel: a cancellation landing exactly as a ContentUri copy finished could skip the .also{} that recorded the temp file, leaking it past the finally block's cleanup. Fixed by assigning the file reference as a plain statement before the copy runs.
• Extracted a deleteIfLocalFile() helper replacing 6 copies of the same guard, and removed CancelPendingInstall's now-dead deleteSourceAfterInstall field.

Verified: unit tests green (including a new test locking in the supersession-cleanup behavior), spotlessApply clean, and the exact race re-tested on-device with the fix in place.

Another /code-review high pass, fixed what it found (commit 08202f8):

A genuine, higher-severity bug this time:TemplateCollectionRepositoryImpl's backup step (moving an existing destFile aside before the swap) had no copyTo fallback - unlike the swap and restore steps a few lines below it, which already have one specifically because renameTo() is known unreliable on-device even for a same-directory move (confirmed earlier in this PR). That meant every overwrite install could fail on exactly the device class this PR already fixed the same issue for elsewhere. Applied the identical fallback to the backup step.

Follow-on from the last fix: the generation-gating I added for the dialog-supersession race didn't cover the installation-completion path - a slow install for an abandoned dialog could still tear down the whole Activity (Finish) out from under a newer, unrelated dialog, and could re-lock that newer dialog's buttons via a shared _isInstalling flag. Extended the same generation check to confirmTemplateInstall()'s completion and to resetting _isInstalling whenever a new dialog is shown.

Also fixed:InstallTempFiles.sweepStale() was doing a full directory scan on every single temp-file creation despite only being able to find anything stale once an hour - throttled to once per 10 minutes.

Note on verification: the physical test device disconnected mid-session, so I couldn't re-verify this round on-device the way I did the last two. Verified instead via the full relevant unit test suite (including a new test locking in the isInstalling scoping fix) and careful tracing - the fix is a direct, narrow extension of the generation-check mechanism from the previous commit, which was verified on-device.

Follow-up: the physical device reconnected, so I re-verified commit 08202f8 on-device after all — fresh install, overwrite (the fixed backup-fallback path), and the dialog-supersession race (two different files in quick succession) all still work correctly, no stray temp/backup files left behind, no crashes in logcat.

`@app/src/main/java/com/itsaky/androidide/repositories/TemplateCollectionRepositoryImpl.kt`:
- Around line 136-164: The replacement flow around installCollection() must
serialize concurrent installations targeting the same canonical destination
path. Hold a per-destination lock across collision detection, staging, backup,
swap, cleanup, and provider reload, so only one call can replace a given
destFile at a time while allowing different destinations to proceed
concurrently.
In `@app/src/main/java/com/itsaky/androidide/utils/InstallTempFiles.kt`:
- Around line 32-33: Update newTempFile and its caller
ExternalFileInstallViewModel.onReceived so temp-directory creation and
sweepStaleIfDue filesystem work run on Dispatchers.IO, either by making
newTempFile suspend or invoking the sweep within the existing IO block; preserve
the current stale-file cleanup behavior.
In
`@app/src/test/java/com/itsaky/androidide/repositories/TemplateCollectionRepositoryImplTest.kt`:
- Around line 93-101: Configure the app test task and dependencies to use the
existing JUnit 4/Robolectric setup from projects.testing.unit rather than
Jupiter; retain RobolectricTestRunner for TemplateCollectionRepositoryImplTest
at
app/src/test/java/com/itsaky/androidide/repositories/TemplateCollectionRepositoryImplTest.kt:93-101
and ExternalFileInstallViewModelTest at
app/src/test/java/com/itsaky/androidide/viewmodels/ExternalFileInstallViewModelTest.kt:141-163,
with no direct migration to Jupiter or useJUnitPlatform() unless supported
integration is added and verified.
In
`@app/src/test/java/com/itsaky/androidide/viewmodels/ExternalFileInstallViewModelTest.kt`:
- Around line 192-193: Update the test around ExternalFileInstallViewModel so
completing the superseded first install does not produce a ShowSuccess effect
for the active request. Verify the UI effect stream remains free of a completion
effect after installDeferred completes, then keep assertions focused on the
second request’s behavior.

On-device verification of d6eb6d0's stuck-dialog fix (R5CN80KZCKD, physical device):

1. Opened core.cgt -> name-collision dialog ("core" already installed) -> tapped Overwrite -> failed with "reserved name" error, dialog stayed open as designed.
2. Tapped Overwrite again (retry) -> logcat confirms a fresh installCollection() call fired and failed the same way - pre-fix, this second tap would have silently no-op'd (pendingConfirmationTempFile stayed null after the first failure).
3. Tapped Cancel on the still-open dialog -> Activity finished cleanly - pre-fix, this would have also silently no-op'd.

No crashes. Confirms the fix works as intended.
