Release 3.18.0 · ocaml/dune

CHANGES:

Support HaikuOS: don't call execve since it's not allowed if other pthreads
have been created. The fact that Haiku can't call execve from other threads
than the principal thread of a process (a team in haiku jargon), is a
discrepancy to POSIX and hence there is a bug about
it. (@Sylvain78, #10953)
Fix flag ordering in generated Merlin configurations (#11503, @voodoos, fixes
ocaml/merlin#1900, reported by @vouillon)

Add (format-dune-file <src> <dst>) action. It provides a replacement to
dune format-dune-file command. (#11166, @nojb)
Allow the --prefix flag when configuring dune with ocaml configure.ml.
This allows to set the prefix just like $ dune install --prefix. (#11172,
@rgrinberg)
Allow arguments starting with + in preprocessing definitions (starting with
(lang dune 3.18)). (@amonteiro, #11234)
Support for opam (maintenance_intent ...) in dune-project (#11274, @art-w)
Validate opam maintenance_intent (#11308, @art-w)
Support not in package dependencies constraints (#11404, @art-w, reported
by @hannesm)

Warn when failing to discover root due to reads failing. The previous
behavior was to abort. (@KoviRobi, #11173)
Use shorter path for inline-tests artifacts. (@hhugo, #11307)
Allow dash in dune init project name (#11402, @art-w, reported by @saroupille)
On Windows, under heavy load, file delete operations can sometimes fail due to
AV programs, etc. Guard against it by retrying the operation up to 30x with a
1s waiting gap (#11437, fixes #11425, @MSoegtropIMC)
Cache: we now only store the executable permission bit for files (#11541,
fixes #11533, @ElectreAAS)
Display negative error codes on Windows in hex which is the more customary
way to display NTSTATUS codes (#11504, @MisterDA)
