- patch_ui.py: wrap shutil.copy2 backup in try/except OSError so a
permission or read-only filesystem error prints a specific diagnostic
instead of crashing the script with a generic 'exited non-zero' message
- install.sh: add early guard that detects pipe-install (bash <(curl ...))
and exits with a clear error pointing to the git clone workflow
- patch_ui.py: find_bundle now matches MARKER so already-patched files
return early and print 'UI already patched' instead of the misleading
'filterByProviders pattern not found' warning
- install.sh: scope warning grep to current run only (record log offset
before apply.sh, tail -c +N to read only new bytes)
- install.sh: fix misleading 'before continuing' wording on warning banner
- install.sh: fix grep anchor (^WARNING: missed [truecloud-patch] WARNING: lines)
- uninstall.sh: add import-middlewared verification after Python detection,
matching apply.sh fallback logic
install.sh: running install.sh after a recover.sh left /data/truecloud-patch/disabled
in place, so apply.sh silently skipped all patching and middlewared restarted
without the patch. Clear the kill switch file before running apply.sh.
uninstall.sh: midclt initshutdownscript.delete was unguarded under set -euo pipefail,
so a delete failure (already-removed entry, transient API error) aborted the script
before sitecustomize.py was cleaned up or /data/truecloud-patch/ was removed. Now
guarded with an if/else that warns and continues.
sitecustomize.py: move importlib.machinery/.util imports inside the if block in
find_spec so they only execute when intercepting our two target modules, not on
every module import across the whole process. In _install(), import os before
importlib.util so the kill switch check (cheap) runs before the importlib import
(slightly heavier on first use). Remove the unused orig variable in _patch_restic.
patch_ui.py: add explicit encoding="utf-8" to both open() calls. errors="replace"
on read so malformed bytes in a bundle don't silently skip a candidate file.
If the patch ever prevents middlewared from starting, users now have a
clear escape hatch that requires no knowledge of Python internals:
bash /data/truecloud-patch/recover.sh
Or at a bare shell prompt:
touch /data/truecloud-patch/disabled
systemctl restart middlewared
sitecustomize.py checks for /data/truecloud-patch/disabled at Python
startup and skips the import hook entirely when the file exists.
apply.sh does the same so the PREINIT script also does nothing on reboot.
recover.sh is copied to /data/truecloud-patch/ by install.sh so it is
available even without the original repo directory.
README gains an "Emergency recovery" section above Troubleshooting.
Patches middlewared at runtime via sitecustomize.py (no file edits to /usr/)
and widens the UI credential dropdown from Storj-only to S3+B2+Storj.
Persists across TrueNAS updates via PREINIT initshutdownscript stored in DB.
