3.24.0~alpha0

CHANGES:

Fixed

• Fix promotion failure when a target changes from a directory to a file
  between builds, causing "Is a directory" errors.
  (#14371, fixes #5647, fixes #6575, @Alizter)

• Make dune build @doc pick up an odoc installed via dune tools install odoc even without DUNE_CONFIG__LOCK_DEV_TOOL=enabled, mirroring how
  dune fmt consumes a locked ocamlformat (#14426, fixes #14235, @mt-caret)

• Reject (package ...) inside a named dependency binding
  ((deps (:name (package foo)))). Previously this was silently accepted but
  %{name} would resolve to an empty path list. (#14499, @Alizter)

• Fix incorrect dependency in the .cmxs build for libraries with
  mode-dependent foreign stubs: the rule depended on the byte stubs archive
  instead of the native one, so parallel builds could fail to find
  -l<lib>_stubs_native. (#14500, fixes #12964, @Alizter)

• Fix dune build failing with "No rule found" when lock_dir paths in
  dune-workspace contain a subdirectory (e.g. (path sub/dune.lock)).
  (#14524, fixes #14523, @Alizter)

• Artifact substitution repairs executable bit if it's not set correctly in the workspace
  (#14556, @rgrinberg)

• Ignore EINVAL when accepting sockets on MacOS (#14612, fixes #12660, @rgrinberg)

• Validate profile names. Profile names must be non-empty and can only contain
  letters, digits, _ and -. The name _ is reserved as a wildcard in
  (env ...) stanzas. (#14657, fixes #14630, @rlepigre)

Added

• Add %{pkg:<package>:<section>:<path>} pform for resolving package install
  files. Works with workspace packages, lock-file packages, and installed
  packages. (#14200, fixes #14193, fixes #3378, @Alizter)

• Enable the relocatable compiler by default for package management (#14357,
  fixes #14012, @Alizter)

• Add changed source files to the build-start trace event for watch-mode
  restarts, showing the paths that triggered the rebuild (#14396, @rgrinberg)

• Add dune's rusage information in start/finish build trace events (#14402, @rgrinberg)

• Add a status message for RPC clients that manage to connect (#14424, @rgrinberg)

• Allow blang expressions in the runtest_alias field in the cram stanza (#14425, @rgrinberg)

• Extend the stat based cache to cache the contents of directories and not just
  source files (#14469, @rgrinberg).

• Show the number of connected RPC clients in the watch mode status line
  (#14489, @rgrinberg)

• Promote directory targets from experimental to generally available in 3.24
  (#14579, @rgrinberg)

Changed

• Use / as directory separator when appending local paths to external paths,
  making path construction consistent across platforms. (#14278, @Alizter)

• On Windows, normalise process paths to \ before passing them to
  CreateProcessW so that programs which scan argv[0] (notably cmd.exe)
  do not misparse mixed separators. (#14278, @Alizter)

• %{bin:NAME} now resolves to the build artifact path rather than
  the install staging path. Rules with %{bin:NAME} deps additionally
  get a per-rule .binaries directory prepended to the action's
  PATH, containing correctly-named symlinks for each declared bin
  pform dep. (#14432, fixes #3324, @Alizter)

• Replace the Rocq language field (stdlib ...) with the presence-only field
  (no_corelib) in Rocq language 0.14. (#14452, fixes #14358, @Durbatuluk1701)

• Throttle sandbox creation to 250 concurrent sandboxes. (#14464, @rgrinberg)

• The package solver now uses cached revision store lookups for improved
  performance. (#14494, fixes #12637, @Alizter, @rgrinberg)

• Remove the deprecated (lang coq) Coq Build Language. Use the
  Rocq Build Language ((using rocq <version>)) instead. Projects that
  still declare (using coq <version>) now get an error pointing them
  at Rocq. (#14525, fixes #12788, @Alizter)
