- Replace extractSlow() per-item extraction with IInArchive.extract() bulk API
in 7-Zip-JBinding. Solid RAR archives no longer re-decode from the beginning
for each item, bringing extraction speed close to native WinRAR/7z.exe (~375 MB/s
instead of ~43 MB/s).
- Add BulkExtractCallback implementing both IArchiveExtractCallback and
ICryptoGetTextPassword for proper password handling during bulk extraction.
- Fix resolveArchiveItemsFromList with multi-level fallback matching:
1. Pattern match (multipart RAR, split ZIP/7z, generic splits)
2. Exact filename match (case-insensitive)
3. Stem-based fuzzy match (handles debrid service filename modifications)
4. Single-item archive fallback
- Simplify caching from Set+Array workaround back to simple Map<string, T>
(the original "caching failure" was caused by resolveArchiveItemsFromList
returning empty arrays, not by Map/Set/Object data structure bugs).
- Add comprehensive tests for archive item resolution (14 test cases)
and JVM extraction progress callbacks (2 test cases).

- JVM extractor now supports --daemon mode: starts once, processes
multiple archives via stdin JSON protocol, eliminating ~5s JVM boot
per archive
- TypeScript side: daemon manager starts JVM once, sends requests via
stdin, falls back to spawning new process if daemon is busy
- Fix extraction progress caching: replaced Object.create(null) + in
operator with Set<string> + linear Array scan — both Map.has() and
the in operator mysteriously failed to find keys that were just set
- Daemon auto-shutdown on app quit via shutdownDaemon() in before-quit
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Replace Map-based archive item cache with plain Object.create(null)
to work around mysterious Map.has() returning false despite set()
being called with the same key — this caused resolveArchiveItems
to run on every 1.1s pulse instead of being cached, preventing
extraction progress (Entpacken X%) from ever showing in the UI
- Apply same fix to both hybrid and full extraction paths
- Increase JVM heap from 512MB to 1GB for better extraction throughput
- Use SerialGC for faster JVM startup on short-lived extract processes
- Add download lifecycle logging (package add + item download start)
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Log when packages are added (count + names)
- Log when individual item downloads start (filename, size, provider)
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Change OS priority from IDLE/BELOW_NORMAL to NORMAL/BELOW_NORMAL so
extraction runs at full speed (matching manual 7-Zip/WinRAR performance)
- Use "high" priority in both hybrid and full extraction paths
- Increase hybrid extraction threads from hardcoded 2 to dynamic
calculation (half CPU count, min 2, max 8)
- Fix emitState forced emit being silently dropped when a non-forced
timer was already pending — forced emits now always replace pending
timers to ensure immediate UI feedback during extraction transitions
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Force immediate emitState when first resolving archive items so UI
transitions from 'Ausstehend' to 'Entpacken X%' instantly
- Use BELOW_NORMAL priority (instead of IDLE) for final extraction
when all downloads are complete — matches manual extraction speed
- Add diagnostic logging for resolveArchiveItems matching
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add "Download fertig: filename (size), pkg=name" log line when an item
finishes downloading, enabling precise timing analysis of when archive
parts become available for extraction.

- Run collectMkvFilesToLibrary in background after each hybrid extraction
round so MKVs are moved to the library as episodes are extracted, not
only after the entire package finishes
- Add timing logs to identify bottlenecks:
- Post-process slot wait time
- Per-round duration with requeue status
- Recovery loop duration
- Setup time in handlePackagePostProcessing
- findReadyArchiveSets duration when > 200ms
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
After a hybrid extraction round completes, set the requeue flag so the
do-while loop immediately checks for more ready archive sets. Previously,
if all items completed before the task started processing, the single
requeue flag was consumed and no new completions triggered re-extraction,
causing 25+ second gaps until the next download completion.
Also change runHybridExtraction return type from void to number
(extracted count) to enable conditional self-requeue only when archives
were actually extracted, preventing infinite requeue loops.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Release post-process slot immediately after main extraction completes.
All slow post-extraction work (nested extraction, auto-rename, archive
cleanup, link/sample removal, empty directory cleanup, MKV collection)
now runs in background via runDeferredPostExtraction so the next package
can start unpacking without delay.
- Export hasAnyFilesRecursive, removeEmptyDirectoryTree, cleanupArchives
from extractor.ts for use in deferred handler
- Import removeDownloadLinkArtifacts, removeSampleArtifacts from cleanup
- Expand runDeferredPostExtraction with full post-cleanup pipeline:
nested extraction, rename, archive cleanup, link/sample removal,
empty dir tree removal, resume state clearing, MKV collection

DDownload is a direct file hoster, not a debrid service. DDownload URLs
are now automatically handled by the DDownload provider when configured,
before trying any debrid providers. Remove DDownload from the
primary/secondary/tertiary provider dropdowns since it only handles its
own URLs and doesn't belong in the debrid fallback chain.

Add proactive disk-busy detection: lower STREAM_HIGH_WATER_MARK from 2 MB

actual backpressure hits.

maxParallelExtract now controls how many archives extract simultaneously
within a single package (e.g. 4 episodes at once). Packages still

handler updated to track multiple active archives independently.

Previously maxParallelExtract allowed multiple packages to extract

When SevenZipJBinding reports "Archive file can't be opened with any
of the registered codecs", the extractor now falls back to legacy
UnRAR instead of failing immediately. Previously, backend mode "jvm"

findNextQueuedItem(), hasQueuedItems(), hasDelayedQueuedItems() and

Require near-complete file size checks in Item-Recovery and hybrid ready-set detection so partially downloaded RAR parts are not marked completed and extracted prematurely.
- Add automatic retry with 3s delay when JVM extractor fails with

(handles transient Windows file locks after download completion)
- Log archive file size before JVM extraction in hybrid mode
- Remove unused ArchiveFormat import, RAR_MULTIPART_RE/RAR_OLDSPLIT_RE

- Keep simple openSevenZipArchive with currentVolumeName tracking

The previous fix blocked ALL multi-part extractions when any item in the

- findReadyArchiveSets: for .part1.rar, require ALL package items

- JVM extractor: remove CRCERROR from isPasswordFailure() — only

7z-JBinding falsely reports encrypted no longer triggers password
cycling.

Root cause: SevenZip.initSevenZipFromPlatformJAR() was never called, so
native compression codecs (RAR5, LZMA2, etc.) were not loaded. Archives
could be opened (header parsing is pure Java) but all extractSlow() calls
returned UNSUPPORTEDMETHOD because no native decoder was available.
- Add ensureSevenZipInitialized() with lazy init before extraction
- Pass password to extractSlow(outStream, password) for RAR5 compatibility
- Add UNSUPPORTEDMETHOD -> legacy fallback in extractor.ts as safety net

Java's getCanonicalFile() resolves subst drives inconsistently,

WinRAR doesn't support \?\ prefix (interprets it as UNC network path).
Replace with subst drive mapping: maps targetDir to a short drive letter
