fix(files): handle double-extensions in withCollisionSuffix
The legacy implementation used lastIndexOf('.') which splits inside
compressed-tarball extensions: foo.tar.gz collided to foo.tar (1).gz,
which then isn't valid as a .gz to unpack and is also ugly.

Recognize the common double-extensions (.tar.gz, .tar.bz2, .tar.xz,
.tar.zst, .tar.lz, .tar.lzma) and treat the entire suffix as a single
logical extension when collision-renaming. So:

  foo.txt          → foo (1).txt              (unchanged)
  foo.tar.gz       → foo (1).tar.gz           (fixed)
  archive.tar.bz2  → archive (1).tar.bz2      (fixed)
  ARCHIVE.TAR.XZ   → ARCHIVE (1).TAR.XZ       (case-insensitive detect)
  subdir/foo.tar.gz → subdir/foo (1).tar.gz   (works with nested paths)
  backup.tar       → backup (1).tar           (single .tar, unchanged)
  config.local.json → config.local (1).json   (multi-dot non-tar, unchanged)
  README           → README (1)               (no extension, unchanged)
  .hidden          → ' (1).hidden'            (legacy quirk preserved)

Detection is lowercase against the basename only, so /path/with.dots/
in folder names doesn't trip the match.

The .hidden edge case (leading-dot basename, no extension) keeps its
legacy '" (1).hidden"' result — fixing it requires changing the dot >
slash predicate which would also shift other behaviors. Marked
separately if anyone wants to revisit.

The helper is exposed on window.__filesOverlay.withCollisionSuffix
and is called from two paths in uploads.js (the upload-conflict
'keep both' branch and the move-conflict 'keep both' branch via
askConflict). Both paths now produce a sensible filename when the
colliding path uses a double-extension.

No pytest tests added: the helper is JS-only and the project has no
JS test framework (per the plan's Out-of-Scope clause). Chromium
manual verification via window.__filesOverlay.withCollisionSuffix
called on 10 inputs confirms each case above.

l4d2-web-app

Flask web app for managing L4D2 servers through user-private blueprints.

Key v1 behaviors

  • Local username/password login; no public signup
  • Admin-managed overlay catalog
  • Private blueprints per user
  • Server creation from blueprints (live-linked; no per-server blueprint overrides)
  • Async job model with persisted command logs in job_logs
  • Desired vs actual state model
  • Live logs for jobs and servers via SSE endpoints
  • Host operations go through l4d2ctl via a local host command runner, not direct l4d2host imports

Frontend constraints

  • Server-rendered templates (Jinja)
  • Vendored HTMX (static/vendor/htmx.min.js)
  • Custom CSS only
  • Tokenized, consistent link and accent colors

Development

From the workspace root (../):

uv sync          # creates .venv, installs l4d2host + l4d2web editable, plus dev deps
uv run pytest l4d2web/tests -q

Configuration

The web app reads these settings from the environment:

  • DATABASE_URL: SQLAlchemy database URL, for example sqlite:////var/lib/left4me/left4me.db.
  • SECRET_KEY: Flask secret key used for sessions and CSRF-sensitive state.
  • JOB_WORKER_THREADS: number of background job worker threads.

In the systemd deployment, environment is loaded from /etc/left4me/host.env and /etc/left4me/web.env.

Admin Bootstrap

Create the first admin account with the Flask CLI. Provide the password through LEFT4ME_ADMIN_PASSWORD:

LEFT4ME_ADMIN_PASSWORD='change-me' flask create-user <username> --admin
