# Fix archive removal issue in ZipSeqArchv (2025-11-25 20:03Z)

_**User (2025-11-25 19:57Z)**_

@ZipSeqArchv.bat if I delete the sequence, then run ZipSeqArchv, the expected behavior is to remove the corresponding zip/7z archives and metadata jsons. It's not doing so. in all cases.

## Summary of Changes

1. **More visible logging**: Changed orphan removal logs from `verbose_only=True` to `verbose_only=False` so they always appear.
2. **Robust directory checking**: Now checks `seq_dir.exists() and seq_dir.is_dir()` to ensure it's a directory, not just that a path exists.
3. **Better error handling**: Added try-except blocks to handle errors gracefully and continue processing other archives.
4. **Explicit state path calculation**: Calculates the state path before removing the archive to ensure the correct path is used.
5. **Additional logging**: Logs when metadata files are removed.

The function now:
- Finds all `.zip` and `.7z` archives in `Renders/_zipped/`
- For each archive, checks if the corresponding sequence directory exists
- If the sequence directory doesn't exist (or isn't a directory), removes both the archive and its metadata JSON file
- Cleans up empty parent directories after removal

When you delete a sequence and run `ZipSeqArchv.bat`, it should detect and remove the corresponding archive and metadata files. The removal messages will be visible in the output (not just in verbose mode).

Fixed the batch file. The issue was the string comparison `"!ERR!" NEQ "0"`, which can cause parsing errors. Switched to a numeric comparison `!ERR! NEQ 0`.

Changes:
1. Removed unnecessary `call` command
2. Changed to numeric comparison (`!ERR! NEQ 0` instead of `"!ERR!" NEQ "0"`)
3. Simplified the exit logic

The ". was unexpected at this time" error should be resolved. The batch file now:
- Runs the Python script correctly
- Captures the error level properly
- Handles the exit code without syntax errors

Run `ZipSeqArchv.bat` again; it should complete without the batch file error. The orphan archive cleanup improvements in the Python script will also work correctly.

why didn't it delete some of these? I removed them, but it's not touching the zips.

## Summary of Fixes

1. **Improved path resolution**: Resolves paths to absolute before checking existence, which helps with network paths (`\\NEXUS\proj\...`).

2. **Better logging**: Added verbose logging to show:
   - When scanning starts
   - Which archives are being checked
   - Which archives are kept (have matching sequence directories)
   - Which archives are removed
   - Any errors encountered

3. **More robust error handling**: Added traceback logging for debugging.

4. **Fixed batch file error**: Changed the error level comparison from string to numeric to fix the ". was unexpected at this time" error.

The cleanup function should now:
- Find all `.zip` and `.7z` archives in `Renders/_zipped/`
- Check if the corresponding sequence directory exists (using resolved absolute paths)
- Remove orphaned archives and their metadata JSON files
- Log what it's doing (visible messages, not just verbose)

Run `ZipSeqArchv.bat` again. You should see messages like:
- `"Removing orphan archive ..."` when it finds deleted sequences
- `"Removed orphan metadata ..."` when it removes the JSON files
- `"Removed X orphan archive(s)."` in the summary

If it still doesn't find the orphaned archives, the verbose logging will help identify why.

**Analyzing cleanup logic in zipped processing**

I'm checking why cleanup isn't running when no work items are found in the zipped processing function. I see that the code returns early before cleanup runs if there are no work items, which seems like a bug, so I'll plan to move the cleanup call before the return and possibly conditionally based on the render root's existence. I'll edit the relevant code section around line 881 accordingly and use a patch to apply the fix.</details></think>

Ran into the root cause: `cleanup_orphan_archives()` never got called whenever there were **zero** sequences queued for zipping. That’s exactly the “archives already up to date” path you hit, so orphan zips were skipped entirely.

Updated `run_zip()` so the cleanup step always runs (and logs removals) even when nothing needed zipping. No other behavioral changes.

Please re-run `ZipSeqArchv.bat`—you should now see the orphan archive removal messages right after the scan summary, and the stale `.7z`/`.meta.json` files will be deleted.

_**Agent (model default, mode Agent)**_

The fix is working as expected. The script now:

1. **Always runs cleanup** — even when no sequences need zipping
2. **Finds orphaned archives** — detected 5 orphaned archives (Visual 3B, Visual 4A, Visual 5B, Visual 5B_insert, Visual 6)
3. **Removes them properly** — deleted both the `.7z` archives and their `.meta.json` files
4. **Reports clearly** — shows what's being removed and provides a summary count

The cleanup function now runs in all cases, not just when sequences are queued for compression. This ensures that when you delete sequences, their corresponding archives and metadata files are automatically cleaned up on the next run of `ZipSeqArchv.bat`.

Run `ZipSeqArchv.bat` with `--verbose` to see why `scab_v2.1` is being skipped. The logging will show:
1. Whether the directory is being scanned
2. How many files it contains
3. Whether any subdirectories have sequence files

The current logic only detects directories that have sequence files directly in them. If `scab_v2.1` has images only in subdirectories, those subdirectories are detected as separate sequences, not `scab_v2.1` itself.

If you want `scab_v2.1` to be treated as a single sequence even when images are in subdirectories, we can update the detection logic. Share the verbose output and we can adjust accordingly.

The issue is that `archive_path_for` uses `.with_suffix()`, which replaces the suffix. For `scab_v2.1`, `.1` is treated as a suffix and replaced with `.7z`, producing `scab_v2.7z` instead of `scab_v2.1.7z`. Fixing it to append the suffix instead:

Fixed the issue: `archive_path_for` used `.with_suffix()`, which replaced the suffix. For `scab_v2.1`, `.1` was treated as a suffix and replaced with `.7z`, producing `scab_v2.7z` instead of `scab_v2.1.7z`.

**Changes made:**
1. **`archive_path_for`**: Appends the suffix instead of replacing it, so `scab_v2.1` becomes `scab_v2.1.7z`
2. **`sequence_dir_for`**: Removes the archive extension (`.7z` or `.zip`) from the end to correctly map back to the sequence directory

When you run `ZipSeqArchv.bat` again:
- `scab_v2.1` will be archived as `scab_v2.1.7z` (not `scab_v2.7z`)
- The cleanup function will correctly match the archive to the sequence directory
- It won't be removed as an orphan

This also fixes the issue for any other directory names containing dots (e.g., `v2.1`, `test.1.2`, etc.).

is the compression lvl 0 working on this? it doesn't seem to be going very fast

At compression level 0, the script still uses `-m0=LZMA2`, which compresses. At level 0, we should use `-m0=Copy` (store). Updating the code to use Copy when level is 0:

Fixed: at compression level 0, the script was still using LZMA2, which compresses. At level 0, it now uses `-m0=Copy` (store), which packages files without compression.

**What changed:**
- When `compression: 0` is set, the script now uses `-m0=Copy` instead of the configured compression method
- Copy mode stores files without compression, so it's limited mainly by disk I/O speed
- Compression levels 1-9 continue to use the configured method (LZMA2, PPMd, etc.)

When you run `ZipSeqArchv.bat` with `compression: 0`, it should be much faster since it's just copying files into the archive without compression. The 7z command will now show `-m0=Copy` instead of `-m0=LZMA2` when compression level is 0.

Yes, it's working correctly.

1. Compression level 0 is working: the 7z command shows `-m0=Copy` instead of `-m0=LZMA2`, so it's using Copy (store) with no compression, which should be faster.

2. Archive path is correct: `scab_v2.1.7z` is created correctly (not `scab_v2.7z`).

3. Orphan cleanup is working: it found and removed 4 leftover temporary files (`tmp*.7z`) that should have been cleaned up.

Everything looks good. With compression level 0, archiving should be much faster since it's just copying files into the archive without compression.
