v1.2.3

daisy v1.2.3

A bug-fix release for the 1.x line. It fixes runs that hang when a worker
process dies, and server address detection on hosts where the default-route
lookup gives the wrong interface. This is the last 1.x release before
daisy 2.0

Fixes

• Dead workers are detected and replaced. A worker that dies without
  reporting back (SIGKILL, OOM kill, SystemExit) used to leave the server
  waiting forever, because no error was queued and no block came back. The
  server now checks worker liveness on every event-loop iteration and starts
  replacements. (#67)
• Workers that exit normally are not replaced. This fixes a follow-on bug
  from #67, where workers that finished cleanly were replaced over and over,
  so the worker count grew without limit. (#68)
• TCP server address detection falls back to loopback. The server finds
  its address by sending UDP toward 8.8.8.8 and reading the default-route IP.
  On some hosts that address can't be used (macOS's application firewall,
  for example, made every TCP test fail with ENOTCONN). daisy now checks
  the detected address with a loopback connection test and falls back to
  127.0.0.1 if it fails. Server and TCPServer take an optional host
  argument to set the address explicitly. (#66)
• No SyntaxWarning on Python 3.14. A return inside a finally block
  is rewritten to suppress exceptions explicitly
  (PEP 765), which removes the warning
  from the logs of downstream daisy/volara workflows. (#65)

Documentation

• The docs build with GitHub Actions, and the API and release pages are
  updated. A new tutorial runs as part of the docs build, so it stays
  up to date and runnable. The old minimal_example and visualize.py
  examples were removed. (#60)

Development

• black is replaced by ruff in the dev extra. A new docs extra
  installs the docs build dependencies.
