2.1.0~beta4 Pre-release
Pre-release

This is a third beta release of opam 2.1.0 (there was a glitch with the number).

This beta release contains quite a few improvements and fixes upon beta3.

Binaries and full archive are signed by opam dev team (fingerprint 92C5 26AE 50DF 3947 0EB2 911B ED4C F1CA 67CB AA92 ).

Overview

A more complete overview of opam 2.1.0~beta4 is on the platform blog.

CLI Versioning

--cli was added in the first beta, but is now used throughout the CLI (see #4385). When invoking opam from a script or program, we recommend using --cli=2.1. If you need to be compatible with 2.0, you can set the environment variable OPAMCLI to 2.0 (this is done automatically by opam when building packages).

As with changes in the Dune language, changes to opam's CLI are now immediate - for example, --unlock-base is now unavailable without selecting the opam 2.0 CLI (you must use --update-invariant). Like Dune, opam tries to be helpful and the errors include pointers to the new syntax.

Other new features

  • opam now exits with code 31 if all failures were during fetch operations (#4214)
  • opam install now has a --download-only flag (#4036), allowing opam's caches to be primed
  • opam init now advises the correct shell-specific command for eval $(opam env) (#4427)
  • post-install hooks are now allowed to modify or remove installed files (#4388)
  • New package variable opamfile-loc with the location of the installed package opam file (#4402)
  • opam update now has --depexts flag (#4355), allowing the system package manager to update too
  • depext support NetBSD and DragonFlyBSD added (#4396)
  • The format-preserving opam file printer has been overhauled (#3993, #4298 and #4302)
  • pins are now fetched in parallel (#4315)
  • os-family=ubuntu is now treated as os-family=debian (#4441)
  • opam lint now checks that strings in filtered package formulae are booleans or variables (#4439)

Bug fixes

  • Sandboxing and init script fixes (#4368 and #4482)
  • stdout of pre- and post-session hooks is now propagated to the user (#4359)
  • Switch-specific hooks now work (#4472)
  • Various fixes to architecture detection (#4462)
  • Don't advertise upgrades to hidden versions (#4432)
  • Don't recompile when modifying the package flags (#4477)
  • opam remove --autoremove <PKG> no longer removes unrelated packages or triggers conflicts with orphaned packages (#4250 and #4332)
  • opam switch --update-invariant not changing the invariant when removing or changing package name (#4353)
  • Fixed updates of the invariant with --update-invariant (#4431) ** NO DESCRIPTION **
  • Various pinning fixes (#4255, #4365, #4348 and #4399)
  • --working-dir now works with local switches (#4433)
  • Handling of filename-encoded pkgname in opam files now works (#4401)
  • Display of package variables when there's no config file now no longer loads switch state and works (#4428)
  • Allow short names and full name paths for ports-based systems for depext; affects OpenBSD, FreeBSD and Gentoo (#4396)
  • Fixed opam option depext-bypass-=["XXX"] (#4428) ** NO DESCRIPTION **
  • opam admin cache now uses the archives cache (#4352)
  • opam admin check --cycles no longer explodes on repositories with huge cliques (#4392)
  • Solver fixes (#4362, #4393 and #4357)
  • Fixed permission denied fallback calling openssl (#4449 - part of #4448)
  • --read-only now causes fewer cache updates (#4467 - part of #4354)

2.1.0~alpha Pre-release
Pre-release

This is the alpha release of opam 2.1.0.

This alpha release contains many new features, please see blog post for some highlights and upgrade instructions.

Binaries and full archive are signed by @AltGr.

Changelog (possibly scripts breaking changes are prefixed with ✘):

New features

Recursive pin

Opam now handles lookup for opam files on subdirectories with recursive, subpath based, and subpath recursive pin: --recursive and --subpath PATH options. On recursive mode, opam goes through subdirectories to find opam files & pin them to their subdirectories. On subpath based mode, opam goes to the given subdirectory to find opam file & pin it to this subdirectory.

Switch Invariant

Define switch base packages as a switch invariant, a generic dependency formula instead of an immutable specific package/version.

  • Define switch invariants rather than "base packages" [#3894 @AltGr] {2.1.0-alpha}

  • Don't warn on switch creation with 'ocaml' as invariant [#4108 @AltGr] {2.1.0-alpha}

  • Better error handling on switch creation [#4121 @AltGr] {2.1.0-alpha}

Lock

opam-lock was during a long time an opam plugin, and it is now integrated into opam. Option --locked permits to lock an opam package, according the current switch. It produces a locked file (by default <pkgname>.opam.locked, can be specified with --lock-suffix) that contains the original opam file with its depends: field all package are set to their exact version available in the current switch.

Options configuration

Replace switch and global variables settings opam config set options, by opam var and opam option to generalize them to all modifiable options and variables:

  • opam var|option: list modifiable options and their values

  • opam var|option foo: display foo value, available for all

  • opam var|option foo(=|-=|+=)bar: update foo value

  • opam var|option foo=: remove/revert foo value

By default, acts on switch scope. It can be specified with --global or --switch sw.

It deprecates opam config (set|unset|set-global-unset-global) commands.

  • Add configuration modifications as opam config subcommands [#3992 @rjbou] {2.1.0-alpha}

  • opam var and opam option outside of opam config [#4116 @rjbou - fix #4119] {2.1.0-alpha}

  • Enable option var optim switch load [#4138 @rjbou] {2.1.0-alpha}

Depext

opam-depext is also a long time opam plugin, used to show / install external dependencies of opam packages. It is now fully integrated in the opam workflow:

  • check of installed package dependencies

  • on install, check that required dependencies are present, show / propose to install if not

Global configuration option depext, depext-verify, depext-cannot-install, depext-run-installs, and depext-bypasspermit to configure depext use and interactions. CLI options--assume-depextsand--no-depexts` can also be used for a single command.

New options

Install

  • opam install --check <pkg> checks that <pkg> dependencies are already installed in the switch. It reports missing ones and exits with 1, 0 otherwise. It is used on a check only purpose, additionally to --deps-only. [#3854 @rjbou - fix #3823] {2.1.0-alpha}

  • --ignore-conflicts to use with --deps-only in case it is needed to install dependencies without taking conflicts into account. [#3853 @rjbou - fix #3846] {2.1.0-alpha}

Show

  • opam show --just-file <file> shows information of a given file, without loading the switch state. It can be combined with other options, as field filter --field. It deprecates --file option. [#3729 @rjbou - fix #3721] {2.1.0-alpha}

  • opam show --all-versions <pkg> displays information of all versions of the given package. It can be used in combination of field filter. [#3867 @rjbou - fix #2980] {2.1.0-alpha}

  • opam show --sort <pkg> display on stdout a sorted opam file: all fields are alphabetically sorted. [#3866 @rjbou - fix ocaml-opam/opam2web#173] {2.1.0-alpha}

  • Better error handling. [#4118 @rjbou - fix #3875] {2.1.0-alpha}

Lint

  • opam lint --check-upstream enables lint checks on archive urls. This option lead to download archives to check their checksum. [#3758 @rjbou] {2.0.5}

List

  • --silent to not write in the output, exit with return code 0 if the list is not empty, 1 otherwise. [#3533 @rjbou - fix #3525] {2.0.1}

Env

  • opam env --check permit to indicates if an opam environment is synchronized: returns 0 if up-to-date, 1 otherwise. [#4074 @rjbou - fix #3725] {2.1.0-alpha}

Switch export

  • --freeze option record VCS commit hash when a VCS url is specified. [#4055 @hannesm] {2.1.0-alpha}

  • With --full option, include extra-files in switch export, on import create an overlay directory with the file contents. [#4040 @hannesm] {2.1.0-alpha}

Enhancements, updates, and fixes

Repository Management

  • Optimize repository loading: we store the repository contents as .tar.gz files in ~/.opam/repo instead. Rather than resorting to a complex in-memory structure, we just untar them to /tmp when they need to be read, and re-tar them after modification (opam update, or format upgrade only). Then we let the OS disk cache do the job: in normal operation, the tree never needs to be flushed to disk, and loading the .tar.gz is orders of magnitude faster than loading the individual files. [#3752 @AltGr - fix l#3721] {2.1.0-alpha}

Fixes

  • Remove mismatching extra-files: sort list before comparing them. [#3744 @rjbou] {2.0.4}

  • Handle failure or interruption of tar during opam update. [#3861 @AltGr] {2.1.0-alpha}

  • Fallback in case repository archive doesn't exist. [#4008 @rjbou] {2.1.0-alpha}

  • In case repository archive is corrupted, delete it and ask to launch an update. [#4075 @rjbou - fix #4053] {2.1.0-alpha}

  • When adding a repository, an error is displayed in case of mismatching urls, now both urls are displayed. [#4086 @rjbou - fix #4085] {2.1.0-alpha}

Update

  • Handle url backend change to VCS of a package from repository. [#4007 @rjbou - fix #3991] {2.1.0-alpha}

Switch & install

  • Allow local compiler switch creation. [#3720 @rjbou - fix #3713] {2.1.0-alpha}

  • Fix multiple compiler candidate. [#3884 @rjbou - fix #3874] {2.1.0-alpha}

  • Make reinstall handling stricter. [#3907 @AltGr] {2.1.0-alpha}

List

Show

  • opam show with local opam file returns local file information. Fixes also the non 1.2 conversion to 2.0 format of local files with opam show --raw. [#3536 @rjbou - fix #3423] {2.0.1}

  • Fields are no longer required to end with a colon. [#3931 @rjbou] {2.1.0-alpha}

  • ✘ With --normalise disable terminal width wrapping. [#3868 @rjbou - fix #3751] {2.1.0-alpha}

  • String fields printed with quotes, as lists. [#3368 @rjbou - fix #3365] {2.0.1}

  • Remove pin depends messages. [#3679 @rjbou] {2.0.2}

Pinning

  • Update source of (version) pinned directory [#3726 @rjbou - fix #3651] {2.0.4}

  • Pin edit: fix editing an opam file without a name field. [#3535 @rjbou] {2.0.1}

  • Upgrade pin depends on pinning. [#3684 @rjbou - fix #3508] {2.0.2}

  • Update pin-depends confirmation message to add a skip option. [#3852 @rjbou - fix #3840] {2.1.0-alpha}

  • To avoid lint warning 57 (description error) on 1.2 opam file pinning, add auxiliary files (descr, url) before linting. [#3687 @rjbou] {2.0.2}

  • Fix --ignore-pin-depends with autopin. [#3736 @AltGr] {2.0.4}

  • Fix pin not installing/upgrading already pinned package. [#3800 @AltGr] {2.0.4}

Working directory

  • Add OPAMDROPWORKINGDIR environment variable for C. [#3792 @rjbou - fix #3727] {2.1.0-alpha}

  • Don't restrain copy to versioned file. [#3759 @rjbou] {2.1.0-alpha}

  • Don't fetch sources when working-dir is set. [#4046 @rjbou] {2.1.0-alpha}

  • Update in place source copy:

    • review sync_dirty on VCS:
      • use VCS to synchronize, then rsync & remove others files
      • exclude _build, _opam & VCS directories
    • when --inplace-build is given, it does a dirty synchronization of the
      sources, in order to keep tracking package stats (clean, local or dirty). [#3948 @rjbou] {2.1.0-alpha}

  • Fix working-dir messages on update command. [#3824 @rjbou] {2.1.0-alpha}

  • Working-dir fixes. [#3982 @rjbou] {2.1.0-alpha}

Download & url management

Download

  • Don't execute validation hook if update is empty. [#3490 @hannesm] {2.0.1}

  • Don't check hash with --no-checksum on pull_upstream. [#3658 @rjbou - fix #3652] {2.0.2}

  • Update download errors handling during actions processing. [#3811 @AltGr] {2.1.0-alpha}

  • Update ftp command, to pass url last. [#3910 @hannesm] {2.1.0-alpha}

  • Terminate (with double dashes) list of command-line download optio...
