0.2.0

Release Notes

The first four changes below can change what an existing project sends or
requires; read them before upgrading.

Changed

• The server needs Python 3.7 or later. Ulak sends its helpers over SSH
  without installing anything. A command that synchronizes stops before
  sending anything if the server lacks python3; ulak doctor reports it.
• A file edited on both ends is held as a conflict instead of last write
  winning. Sync compares both copies with the content the two ends last
  agreed on. A file changed on both is kept on both and named in a warning,
  and a file deleted here is not deleted there if the server changed it.
  Before there is agreed content, [sync] no_history decides: send (the
  default) sends this machine's copy and names each file it sent; hold
  keeps both. ULAK_SYNC_NO_HISTORY sets it too.
• .gitignore is no longer read, because Docker does not read it either.
  Mounted directories sync whole except .git, .DS_Store and Ulak's
  temporary files; build contexts are still filtered by .dockerignore. Use
  [sync] exclude to keep paths local; [sync] include overrides both.
• [sync] paths are relative to the Compose project directory, not to
  the workspace anchor; ../ reaches a sibling. Projects whose anchor is the
  project directory are unaffected.
• Saves, deletions and small server output travel over one persistent SSH
  channel; large files and new directories still use rsync. A full sync
  compares both ends by directory digests and hands rsync only what differs.
  On Linux servers with Python 3.9 or later, files the stack writes come back
  shortly after they change.
• Pulled files land through directories held open from the project root, so
  a directory swapped for a symlink cannot redirect them.
• The background service picks up [sync] changes without a restart.

Added

• ulak ui (beta): a full-screen terminal dashboard for the server's Docker.
  It shows containers grouped by Compose project with live CPU and memory,
  merged stack logs with search, inspect, stats, images, volumes, networks
  and this machine's live stacks. Keys and layout may still change; see
  docs/dashboard.md.
• ulak status, sync, doctor and clean take a stack's Compose project
  name and work from any directory; ulak status alone shows every stack
  declared in the checkout. Write name@server when two servers have a stack
  of that name; see docs/stacks.md.
• --raw on those four commands prints suggested commands in full instead of
  by stack name.

Fixed

• A file saved during a sync no longer becomes a permanent conflict: it is
  sent as it is then, or, if it changes while being read, waits for the next
  sync.
• A directory a pull brings home keeps the server's mode, so later pushes no
  longer fail on directories the SSH user does not own.
• A profile that stays inside the project keeps the wider layout the
  workspace already uses, instead of asking to run again on every run.
• After a reinstall, the service warns that it is still running the build it
  started from.
