Changelog:

Changes

Pin

  • [BUG] Fix an opam 2.1 regression where the initial pin of a local VCS directory would store untracked and ignored files. Those files would usually be cleaned before building the package, however git submodules would not be cleaned and would cause issues when paired with the new behaviour added in 2.3.0~alpha1 which makes opam error when git submodules fail to update (was previously a warning) [#6221 @rjbou - fix #5809]

Var

  • [BUG] Fix a regression which would make opam crash on platforms where getconf LONG_BIT is not available (e.g. OpenBSD) [#6230 @kit-ty-kate - fix #6215]

Actions

  • [BUG] Fix the installed packages internal cache, which was storing the wrong version of the opam file after a build failure. This could be triggered easily for users with custom repositories with non-populated extra-files [#6213 @kit-ty-kate]

Lint

  • [BUG] Fix a regression in lint W59 with local urls that are not archives [#6219 @rjbou - fix #6218]

Build

  • Bump to lang dune to 2.8 and bump the requirement to dune >= 2.8, which was actually required in the previous alpha release [#6204 @kit-ty-kate]
  • Bump the vendored version of dune to 3.16.0, cppo to 1.7.0 and extlib to 1.8.0 [#6223 @kit-ty-kate]
  • Fix compilation with OCaml 5.3 when using the vendored extlib by updating to the 5.3 compatible version (e.g. make cold or ./configure --with-vendored-deps) [#6223 @kit-ty-kate]
  • Fix the compilation of opam on Windows with OCaml >= 5.0 (again) [#6216 @kit-ty-kate]

Release scripts

  • Fix the release script after the bump of dune lang to 2.6 [#6204 @kit-ty-kate]
  • Fix the release script after the introduction of opam_core_stubs [#6204 @kit-ty-kate]
  • Improve the release script by ignoring interactive questions asked by the FreeBSD package manager [#6204 @kit-ty-kate]

Testing and documentation

API updates

opam-state

  • OpamSwitchState.Installed_cache: export load function [#6233 @rjbou]

opam-core

  • OpamStd.Sys.{get_terminal_columns,uname,getconf,guess_shell_compat}: Harden the process calls to account for failures [#6230 @kit-ty-kate - fix #6215]
  • OpamStd.Sys.{uname,getconf}: now accepts only one argument as parameter, as per their documentation [#6230 @kit-ty-kate]
  • OpamSystem: add is_archive_from_string that does the same than is_archive but without looking at the file, only analysing the string (extension) [#6219 @rjbou]
