[rgrinberg]

Embed build informations inside executable

• Project page: https://github.com/ocaml/dune
• Documentation: https://dune.readthedocs.io/

CHANGES:

• Write intermediate files in a .mdx folder for each mdx stanza
  to prevent the corresponding actions to be executed as part of the @all
  alias (Write mdx files to .mdx dir to avoid running mdx as part of @all dune#3659, @NathanReb)

• Read Coq flags from env ([coq] pick flags from profile dune#3547 , fixes [wish] setting coq.theory.flags from a profile dune#3486, @gares)

• Allow bisect_ppx to be enabled/disabled via dune-workspace. (Stop passing external lib deps mode dune#3404,
  @stephanieyou)

• Formatting of dune files is now done in the executing dune process instead of
  in a separate process. (Format dune files in core dune#3536, @nojb)

• Add a --debug-artifact-substution flag to help debug problem with
  version not being captured by dune-build-info (Add a flag --debug-artifact-substitution to help debug problems related to dune-build-info dune#3589,
  @jeremiedimino)

• Allow the use of the context_name variable in the enabled_if fields of
  executable(s) and install stanzas. (Allow context_name in enabled_if of exectuable(s) and install stanzas dune#3568, fixes Allow context_name in enable_if dune#3566, @voodoos)

• Fix compatibility with OCaml 4.12.0 when compiling empty archives; no .a file
  is generated. (In OCaml 4.12.0, empty archives no longer generate .a files dune#3576, @dra27)

• $ dune utop no longer tries to load optional libraries that are unavailable
  (filter unavailable optional libs for utop dune#3612, fixes dune utop fails with optional packages dune#3188, @anuragsoni)

• Fix dune-build-info on 4.10.0+flambda (Protect link-time code generation placeholders with Sys.opaque_identity dune#3599, @emillon, @jeremiedimino).

• Allow multiple libraries with inline_tests to be defined in the same
  directory (Allow multiple inline tests in a directory dune#3621, @rgrinberg)

• Run exit hooks in jsoo separate compilation mode (Fix separate compilation of jsoo dune#3626, fixes Discrepancy between jsoo whole program compilation and separate compilation.  dune#3622,
  @rgrinberg)

• Add (alias ...), (mode ...) fields to (copy_fields ...) stanza (Add (alias ...), (mode ...) fields to (copy_files ...) stanza dune#3631, @nojb)

• (copy_files ...) now supports copying files from outside the workspace using
  absolute file names ((copy_files ...): support external paths dune#3639, @nojb)

• Dune does not use ocamlc as an intermediary to call C compiler anymore.
  Configuration flags ocamlc_cflags and ocamlc_cppflags are always prepended
  to the compiler arguments. (Directly call the C compiler  dune#3565, fixes Change the way we call the C compiler dune#3346, @voodoos)

• Revert the build optimization in Build .cmx/.o files more eagerly for executables dune#2268. This optimization slows down building
  individual executables when they're part of an executables stanza group
  (Revert optimization introduced in #2268 dune#3644, @rgrinberg)

• Use {dev} rather than {pinned} in the generated .opam file. (Opam file generation: Use {dev} instead of {pinned} when calling dune subst dune#3647,
  @kit-ty-kate)

• Insert correct extension name when editing dune-project files. Previously,
  dune would just insert the stanza name. (Fix #3624 dune#3649, fixes Dune appends (using coq.theory 0.2) instead of (using coq 0.2) dune#3624, @rgrinberg)

• Fix crash when evaluating an mdx stanza that depends on unavailable
  packages. (Fix evaluate-time error with MDX stanza and unavailable packages dune#3650, @craigfe)

• Fix typo in cache-check-probablity field in dune config files. This field
  now requires 2.7 as it wasn't usable before this version. (Fix typo in (cache-check-probablity) dune#3652, @edwintorok)

• Add "odoc" {with-doc} to the dependencies in the generated .opam files.
  (opam file generation: Add odoc {with-doc} to the dependencies dune#3667, @kit-ty-kate)

• Do not allow user actions to capture dune's stdin (Launch process without stdin by default dune#3677, fixes User actions are connected to dune's stdin dune#3672,
  @rgrinberg)

• (subdir ...) stanzas can now appear in dune files used via (include ...).
  (Allow (subdir ...) in dune files used via (include ...) dune#3676, @nojb)

[kit-ty-kate]

I believe ocaml/dune#3585 should've been merged before releasing this version. It seems a bit inconsistent to me if dune 2.6.2 supports OCaml 4.12 but not dune 2.7.0

[kit-ty-kate]

oh nevermind, the commit has been cherry-picked but the PR is still there for some reason

[avsm]

@voodoos notes that there is a regression:

Dune now checks that the field name(s) in exectuable(s) stanzas contains only valid module names. (ocaml/dune#3646)
However in https://github.com/garrigue/lablgtk the example folder contains an executable with name dialog-thread in a file named dialog-thread.ml.
The compiler accepts that file but the new dune doesn't.

[voodoos]

We decided to postpone that new check of the name field of executables stanzas.

[rgrinberg]

I've glanced over the failures, and I don't see anything noteworthy.

[avsm]

Also lgtm, just waiting for CI run to pass in a few hours

[kit-ty-kate]

Looks good. Thanks!
