Is there a reason that the default ripping directory needs to change?
This would create a breaking change for users which rely on the default config file (especially those using Docker or a unix-like environment)

I just did a fresh install of HandBrake (Windows 11, 64bit) the default install path was 'C:\Program Files\HandBrake', but there's no HandBrakeCLI.exe file, just 'HandBrake.exe' and 'HandBrake.Worker.exe'.
I'm not super familiar with the CLI for HandBrake; which of these should AutoRip be using?

I asked AI to update the documentation for the HandbrakeCLI (which is a separate install). Does it work better now?

Thanks for the work on this @johnml1135! I left comments on a few specific areas of your changes.
Additionally, how would this work for users using MakeMKV-Auto-Rip via Docker? So far, the goal has been to maintain feature parity between the Docker distribution and other installations. I'd prefer to maintain that if you're willing to contribute the energy to solving that issue. Alternatively, we should at least call it out in the README and other documentation until myself or someone else has time to implement it.
Similar to my Docker comment, the web interface should also be updated so that the new HandBrake configuration options can be modified from the existing configuration menus too.
P.S. It looks like code coverage dropped a bit below the 80% target with this PR as well.

I don't think this retry code is getting called anywhere. I'm fairly sure that conversion would fail to retry if a situation that required a retry occurred.
I'm a little on the fence for how necessary it is to have a retry ability in the first place for something like this. I wonder what situations would cause HandBrake to fail at first, but succeed when ran a second time.
But overall, a good addition as long as it's properly implemented.

I don't know either - would you like me to rip it out? AI added it.

I don't see the 'HANDBRAKE_STRICT_VALIDATION' var used anywhere in the code, what is this supposed to accomplish?

A few things I noticed about the HandBrake argument handling
Issues:
- Silent failure (warning only) means users won't know their args were ignored
- The regex doesn't catch all dangerous patterns (e.g., >, <, \n, etc.)
Recommendation:
- Throw an error instead of just warning
- Use child_process.spawn with array arguments instead of exec with a shell string

Why remove the object freeze logic from this? Originally I had added this to help prevent accidentally mutating our constants in the app logic.

We should do something similar to how we report a success/failure array for ripping discs for when HandBrake processing passes/fails, so that users have good visibility into the status of each disc.

I don't fully know what you are asking for here.

I can try to make a few of these fixes - but honestly, I am experienced as a C# and python developer, but not with JS. I had copilot do 99% of it. I can make more changes, but it would be merely instructing Copilot to do it and I don't know if it is doing something wrong (without more effort than I am able to put in right now). |
- Reverted movie_rips_dir to ./media (no breaking change) - Disabled HandBrake by default in config.yaml - Updated HandBrakeCLI documentation - clarified it's a SEPARATE download from GUI * Added direct links to CLI download page (downloads2.php) * Noted Windows CLI comes as ZIP file, not installer * Updated example paths to reflect user's extraction location - Restored Object.freeze() on all constants to prevent mutation - Enhanced argument validation to throw errors (not just warn) for unsafe characters - Improved dangerous character regex to catch more patterns (>&<\n\r) - Implemented retry logic - now properly called on conversion failures * Automatic fallback to simpler presets on failure * Original MKV always preserved on failure - Added HandBrake success/failure tracking arrays * goodHandBrakeArray and badHandBrakeArray similar to disc ripping * Results displayed in displayResults() method - Removed unused HANDBRAKE_STRICT_VALIDATION environment variable from docs - Updated integration test to expect new error-throwing behavior All 433 tests passing

Hi @johnml1135 I'll take a look this weekend, sorry I haven't gotten back to you sooner. Super busy week for me haha |

No, rush - honestly I just made the updates for myself and I can use them as-is. I hope others can benefit from the work as well. |
- Consolidate duplicate validation: Use validateHandBrakeConfig() from handbrake-config.js in AppConfig.validate() instead of duplicating logic - Convert sync file operations to async: Replace fs.existsSync/statSync/openSync/readSync with fs/promises in validateOutput() - Add log verbosity control: Add Logger.debug() method and verbose mode toggle to reduce console noise - Convert verbose logging to debug: Change ~30 Logger.info() calls to Logger.debug() for detailed output - Add tests for Logger: Add 8 new tests for debug() and setVerbose()/isVerbose() methods - Update handbrake.service tests: Fix mocks for new async fs/promises implementation Coverage: 80.77% overall (473 tests passing)
Rip mode frequently stopped picking up the next disc. Four causes: - The loop waited for the drives to be seen *empty* before it would rip again. Detection is paused for the whole rip cycle, so a disc swapped in during that window meant the drive was never observed empty and the loop waited forever with a fresh disc sitting in it. It now also treats a disc whose drive/label differs from the one just ripped as new. - A failed detection returned "no discs", which read as "the disc was removed" and let the still-loaded disc be ripped a second time. Detection failures are now distinguished from an empty drive. - The rip cycle blocked on the HandBrake queue, so the drive sat idle - and the loop stayed blind to disc changes - for the length of an encode. Rip mode now keeps one RipService per session and lets HandBrake encode in the background while the next disc is detected and ripped. - Mount-detection polling could re-report a disc the initial detection had already found, and both entries were ripped: two MakeMKV jobs against one drive, leaving a spurious "-1" copy. Discs are now merged by drive. Also: WebService.listen() passed its callback to server.listen(), which is the 'listening' listener, not an error callback - so EADDRINUSE went unhandled and a second `npm run web` could keep running headless, polling and ripping alongside the first instance. It now fails with a clear message. Cleanups: give the rip exec() a real maxBuffer (exceeding the 1 MB default kills makemkvcon mid-rip), use the folder handed to MakeMKV as the authoritative output dir instead of re-parsing it out of the log, and move the per-line MakeMKV output dump to debug level.

Replace the regex-based config.yaml writer with the yaml library's document API. The old version resolved a nested key by matching the first line in the file using that name at any indentation, so saving from the web UI wrote `handbrake.enabled` (and then `handbrake.subtitles.enabled`) into `paths.logging.enabled`, and never saved the HandBrake flag at all. The replacement sets values by full key path and preserves comments, ordering and quoting; it is ~35 lines instead of ~150, and now has tests, which that path had none of. Also removed with it: deepMerge and deleteKeyValue (both dead), an unused yaml import, and currentStopRequested (written in four places, read in none). Other fixes: - cli/commands.js awaited AppConfig.validate(), so a bad config surfaced as an unhandled rejection instead of the command's own error handling. - createUniqueFolder now creates parent directories, so a configured media directory that does not exist yet does not fail the rip with ENOENT. - FileSystemUtils.readdir/unlink logged two info lines per call, which the web UI shows; they are debug now.

Diagnosis of the 2-hour TL15_MARTIN_LUTHER rip, from logs/Log-TL15_MARTIN_LUTHER* and the process tree: two web instances were ripping the same disc at once, each seeking to a different title on one drive. 2h05m of video took 2h16m - about 1x. The second instance then failed with "MEDIUM NOT PRESENT - TRAY OPEN" when the first one finished and ejected. The instance conflict is fixed by the EADDRINUSE handling in the previous commits; this commit covers what that episode exposed. Recovery visibility. The helper script sent ddrescue's status display to /dev/null, so a recovery that can run for an hour logged nothing between "pass 1 start" and "pass 1 done". ddrescue's status block is now parsed and summarised once a minute (immediately for the first sample): [ddrescue] DISC: Recovering: 44.65% of the disc read - 2.02 GB of 4.52 GB recovered - 12 damaged area(s), 1.4 MB unreadable so far - 5m 12s elapsed, 1m 40s of it on damaged areas - about 6m 30s left - 14m of recovery budget left Time is attributed to damaged areas when a sample shows new read errors or more unreadable bytes than the previous one, or when ddrescue is in a trim/scrape/retry phase. Recovery budget. max_runtime was a flat 90m regardless of the disc. The budget is now a multiple of the rip that just failed (max_runtime_ratio, default 1), floored at min_runtime (10m) and still capped by max_runtime, so best-effort recovery costs roughly one extra rip rather than an open-ended hour. Tray-open is no longer treated as disc damage. MakeMKV reports a removed disc through the same MSG:2003 read-error code as a bad sector; imaging a disc that is not in the drive is pointless. Those failures now say what actually happened instead of starting a recovery. Speed and visibility during the rip itself: - makemkvcon --progress=-same drives a once-a-minute progress line, so a disc reading at 1x is visible while it happens. PRG* lines are stripped from the saved log so it stays readable. - New ripping.read_cache_mb (makemkvcon --cache, default 256). - HandBrake encodes run at below-normal priority; now that they overlap the next disc's rip, they should never be what MakeMKV waits behind.

The summaries added in the previous commit were emitted from the operation's own output stream, so they stopped exactly when they mattered: a drive grinding through a defect produces no ddrescue status lines and no MakeMKV PRGV lines for minutes at a time, and the log went quiet. A shared ProgressHeartbeat now owns the timing. The streams only update state; the timer asks for a description every 60s and always logs one: - Ripping: percentage and elapsed time, plus "no progress for 4m (the drive may be retrying a damaged area)" once nothing has advanced for 90s. Before any progress arrives it still reports elapsed time. - Recovery: the full ddrescue summary, including "waiting for the first ddrescue status" before the first sample and the same stall notice after. - Encoding: percentage parsed from HandBrakeCLI's output and elapsed time. This phase had no periodic reporting at all, and it runs for tens of minutes alongside the next disc's rip. Timers are unref'd and stopped on close/error, so they cannot outlive the work or hold the process open. Recovery elapsed time is now wall clock rather than ddrescue's own run time, which excludes setup and flushing the image - a live check showed it reporting "2s elapsed" 25 seconds in. The budget is wall clock, so the reported figure should be too. formatBytes/formatDuration moved to utils/format.js; three modules need them now, and reaching into recovery.service.js for a formatter was the wrong shape.

A hard MakeMKV failure ran the recovery gate twice: ripSingleDisc checked isReadErrorFailure itself, then called attemptReadErrorRecovery which checks the same thing plus platform, tooling and the new medium-absent case. The two copies had already drifted - a tray-open failure passed the caller's check but not the callee's, so the "the disc was removed" explanation was only reachable from the success path. Worse, the caller treated "recovery did not throw" as "the disc was salvaged", so a rip that failed with recovery disabled, or unavailable, or producing nothing, resolved as a successful rip and was recorded in neither the good nor the bad list. attemptReadErrorRecovery now returns whether it actually produced a title, the caller gates on that, and the duplicated check is gone. Also removed: - RecoveryProgressTracker.totals(), which I added last commit and never called from anything but its own tests; the summary already reports those numbers, so the tests now assert on it. - FileSystemUtils.ensureDirectoryExists and MakeMKVMessages.hasCriticalErrors, neither called from anywhere. - RIP_PROGRESS_INTERVAL_MS, a second copy of the heartbeat's own 60s default. Added tests for the encode-phase progress and priority code, which had none. Verified against Node that promisify(execFile) really does expose .child with live stdout/stderr, since silently getting that wrong would have made encode progress a no-op.

rip.service.js was 1,388 lines across four jobs. The read-error recovery
workflow - imaging a damaged disc, re-ripping from the image, image locking,
free-space and retention handling - is now ReadErrorRecovery in its own module
(898 + 584 lines). It needs exactly two things from the ripper, so both are
injected: a cancellation seam and a callback for handing recovered files to the
encode queue. Its tests target it directly instead of reaching through
RipService, which is what they were really testing all along.
That also removed a duplicated block: queueing MKVs for HandBrake existed twice
with slightly different guards. One queueForEncoding method now serves the
normal rip path and recovery.
waitForDriveMount had two problems. It counted poll attempts rather than
elapsed time, and each attempt costs two makemkvcon invocations - so on a slow
drive a "10 second" wait could run for minutes. It is wall-clock now. It also
tracked "discs new since we started", with a baseline that a failed first poll
left at zero, making every disc look new; since the caller merges by drive
number anyway, it simply reports everything it can see. That deletes the
baseline bookkeeping and one makemkvcon call per wait.
NativeOpticalDrive.isNativeAvailable threw on the first call when the addon was
missing and returned false on every call after, so the same failure produced
two different errors depending on ordering. It answers false consistently now.
Also dropped: its unused ejectAllDrives/loadAllDrives (OpticalDriveUtil does its
own iteration), four `try { ... } catch (e) { throw e }` wrappers, and
getDefaultHandBrakeConfig/mergeHandBrakeConfig, a second source of truth for
HandBrake defaults that nothing called.
Verified the app still boots and serves /api/status, /api/info and
/api/config/structured after the move.
