Add (paths ...) field to (context ...) definition #2426

nojb · 2019-07-18T14:03:00Z

This PR proposes a new field (add-to-path <string list>) to the env stanza. The strings are interpreted as paths and added to the PATH. This happens before the context is set up, so in particular the resulting PATH is used to look up the compiler tools.

Like env-vars, it is only supported on the workspace file for now.

The main motivation is #1692 (allowing to set the compiler path independently of the environment)

Allowing to add paths to a build context seems like a good idea. However, if we allow to do this in the env stanza, then one is able to modify the path in any dune file. That part feels a bit dodgy to me, or at least it requires to think carefully about how it impacts binaries resolution.

What about adding this field to Workspace.Context.Common.t instead?

Well, actually this is only interpreted in the workspace file (like env-vars I think); it is ignored in other dune files.

But yes, I agree we can add it to the context stanza directly, that's enough for my use case. I will do the change.

nojb · 2019-07-18T15:02:28Z

I did the suggested change and added some words to to the manual about the new field.

nojb · 2019-07-18T15:43:04Z

I wonder if we should support a more general (add-to-list VAR ...) to extend any PATH-like variable.

nojb · 2019-07-18T15:48:34Z

(I'm thinking of things like CAML_LD_LIBRARY_PATH)

rgrinberg · 2019-07-21T06:02:30Z

How about having an OSL field for path?

For example: (paths :standard new-path). This seems a bit more consistent with the rest of the dune language.

I don't see why not. Here :standard is supposed to stand for the existing value of the environment variable, right?

For analogy with env-vars and to make it a bit more general, what do you think about :

(env-path (PATH :standard new-entry) (CAML_LD_LIBRARY_PATH ...))

rgrinberg · 2019-07-22T06:03:57Z

Sounds good to me. Which just need a better name than env-path.

nojb · 2019-07-22T21:49:14Z

Sounds good to me. Which just need a better name than env-path.

I went with (paths ...) like you suggested.

nojb · 2019-07-22T21:52:28Z

This can be reviewed again.

ghost · 2019-07-23T12:04:18Z

src/context.ml

+  in
+  let vars =
+    let cwd = Sys.getcwd () in
+    let of_filename_relative_to_cwd s =


What about: Path.of_string s |> Path.to_absolute_filename? That would make the path be interpreted relative to the workspace root, which is consistent with how other paths are interpreted.

I thought the current code did that (isn't cwd the workspace root?), but anyway your suggestion is much cleaner.

Yep, the current does that but it seems better to me to leave that job to Path

ghost · 2019-07-23T12:06:29Z

src/context.ml

+    in
+    let sep = String.make 1 Bin.path_sep in
+    let f l = String.concat ~sep (List.map ~f:of_filename_relative_to_cwd l) in
+    Env.Map.of_list_reduce t ~f:List.append |> Env.Map.map ~f


Does this of_list_reduce means that we can have the same variable several times inside (paths ...)?

i.e.:

(paths (PATH ...) (PATH ...) )

?

That feels dodgy. We should forbid such cases.

Yes, it means that; and yes, it is dodgy. Will amend the code to fail in that case.

This is now fixed.

nojb · 2019-07-24T20:04:38Z

I think all issues have been addressed.

ghost · 2019-07-25T12:39:24Z

Looks good! Could you just move the duplicated variable check to workspace.ml directly? This way we get the error right at parsing time. Appart from that it's good to merge.

This is done, but the test fails on Windows it seems; I am investigating.

nojb · 2019-07-25T15:02:21Z

Ok, I figured out why it wasn't working on Windows (see last commit) and am happy again. Unless someone objects I will merge once I get the CI to pass.

rgrinberg · 2019-07-25T15:17:44Z

Looks good but please squash the commits or rewrite the history into something that can be followed.

nojb · 2019-07-25T15:19:44Z

Thanks, I will squash before merging, it is a small patch anyway.

Oh no! I meant to click on squash and merge but made a mistake and did a regular merge. Sorry everyone!

ghost · 2019-07-29T08:28:13Z

no worries, but yeah, in general let's try to keep master tidy :)

(ocaml/dune#2659, RFC ocaml/dune#2650, @snowleopard) - Add (deprecated_package_names) field to (package) declaration in dune-project. The names declared here can be used in the (old_public_name) field of (deprecated_library_name) stanza. These names are interpreted as library names (not prefixed by a package name) and appropiate redirections are setup in their META files. This feaure is meant to migrate old libraries which do not follow Dune's convention of prefixing libraries with the package name.

(ocaml/dune#2456, @rgrinberg) - Add a new config option `sandboxing_preference`, the cli argument `--sandbox`, and the dep spec `sandbox` in dune language. These let the user control the level of sandboxing done by dune per rule and globally. The rule specification takes precedence. The global configuration merely specifies the default. (ocaml/dune#2213, @aalekseyev, @diml) - Remove support for old style subsystems. Dune will now emit a warning to reinstall the library with the old style subsystem. (ocaml/dune#2480, @rgrinberg) - Add action (with-stdin-from <file> <action>) to redirect input from <file> when performing <action>. (ocaml/dune#2487, @nojb) - Change the automatically generated odoc index to only list public modules. This only affects unwrapped libraries (ocaml/dune#2479, @rgrinberg) - Set up formatting rules by default. They can be configured through a new `(formatting)` stanza in `dune-project` (ocaml/dune#2347, fixes ocaml/dune#2315, @emillon) - Change default target from `@install` to `@all`. (ocaml/dune#2449, fixes ocaml/dune#1220, @rgrinberg) - Include building stubs in `@check` rules. (@rgrinberg, ocaml/dune#2530) - Get rid of ad-hoc rules for guessing the version. Dune now only relies on the version written in the `dune-project` file and no longer read `VERSION` or similar files (ocaml/dune#2541, @diml) - In `(diff? x y)` action, require `x` to exist and register a dependency on that file. (ocaml/dune#2486, @aalekseyev) - On Windows, an .exe suffix is no longer added implicitly to binary names that already end in .exe. Second, when resolving binary names, .opt variants are no longer chosen automatically. (ocaml/dune#2543, @nojb) - Make `(diff? x y)` move the correction file (`y`) away from the build directory to promotion staging area. This makes corrections work with sandboxing and in general reduces build directory pollution. (ocaml/dune#2486, @aalekseyev, fixes ocaml/dune#2482) - `c_flags`, `c_names` and `cxx_names` are now supported in `executable` and `executables` stanzas. (ocaml/dune#2562, @nojb) Note: this feature has been subsequently extended into a separate `foreign_stubs` field. (ocaml/dune#2659, RFC ocaml/dune#2650, @snowleopard) - Remove git integration from `$ dune upgrade` (ocaml/dune#2565, @rgrinberg) - Add a `--disable-promotion` to disable all modification to the source directory. There's also a corresponding `DUNE_DISABLE_PROMOTION` environment variable. (ocaml/dune#2588, fix ocaml/dune#2568, @rgrinberg) - Add a `forbidden_libraries` field to prevent some library from being linked in an executable. This help detecting who accidently pulls in `unix` for instance (ocaml/dune#2570, @diml) - Fix incorrect error message when a variable is expanded in static context: `%{lib:lib:..}` when the library does not exist. (ocaml/dune#2597, fix ocaml/dune#1541, @rgrinberg) - Add `--sections` option to `$ dune install` to install subsections of .install files. This is useful for installing only the binaries in a workspace for example. (ocaml/dune#2609, fixes ocaml/dune#2554, @rgrinberg) - Drop support for `jbuild` and `jbuild-ignore` files (ocaml/dune#2607, @diml) - Add a `dune-action-plugin` library for describing dependencies direcly in the executable source. Programs that use this feature can be run by a new action (dynamic-run <progn> ...). (ocaml/dune#2635, @staronj, @aalekseyev) - Stop installing the `ocaml-syntax-shims` binary. In order to use `future_syntax`, one now need to depend on the `ocaml-syntax-shims` package (ocaml/dune#2654, @diml) - Add support for dependencies that are re-exported. Such dependencies are marked with`re_export` and will automatically be provided to users of a library (ocaml/dune#2605, @rgrinberg) - Add a `deprecated_library_name` stanza to redirect old names after a library has been renamed (ocaml/dune#2528, @diml) - Error out when a `preprocessor_deps` field is present but not `preprocess` field is. It is a warning with Dune 1.x projects (ocaml/dune#2660, @Julow) - Dune will use `-output-complete-exe` instead of `-custom` when compiling self-contained bytecode executables whenever this options is available (OCaml version >= 4.10) (ocaml/dune#2692, @nojb) - Add action `(with-accepted-exit-codes <pred> <action>)` to specify the set of successful exit codes of `<action>`. `<pred>` is specified using the predicate language. (ocaml/dune#2699, @nojb) - Do not setup rules for disabled libraries (ocaml/dune#2491, fixes ocaml/dune#2272, @bobot) - Configurator: filter out empty flags from `pkg-config` (ocaml/dune#2716, @AltGr) - `no_keep_locs` is a no-op for projects that use `lang dune` older than 2.0. In projects where the language is at least `2.0`, the field is now forbidden. (ocaml/dune#2752, fixes ocaml/dune#2747, @rgrinberg) - Extend support for foreign sources and archives via the `(foreign_library ...)` stanza as well as the `(foreign_stubs ...)` and `(foreign_archives ...)` fields. (ocaml/dune#2659, RFC ocaml/dune#2650, @snowleopard) - Add (deprecated_package_names) field to (package) declaration in dune-project. The names declared here can be used in the (old_public_name) field of (deprecated_library_name) stanza. These names are interpreted as library names (not prefixed by a package name) and appropiate redirections are setup in their META files. This feaure is meant to migrate old libraries which do not follow Dune's convention of prefixing libraries with the package name. (ocaml/dune#2696, @nojb) - The fields `license`, `authors`, `maintainers`, `source`, `bug_reports`, `homepage`, and `documentation` of `dune-project` can now be overriden on a per-package basis. (ocaml/dune#2774, @nojb) - Change the default `modes` field of executables to `(mode exe)`. If one wants to build a bytecode program, it now needs to be explicitly requested via `(modes byte exe)`. (ocaml/dune#2851, @diml) - Allow `ccomp_type` as a variable for evaluating `enabled_if`. (ocaml/dune#2855, @dra27, @rgrinberg) - Stricter validation of file names in `select`. The file names of conditional sources must match the prefix and the extension of the resultant filename. (ocaml/dune#2867, @rgrinberg) - Add flag `disable_dynamically_linked_foreign_archives` to the workspace file. If the flag is set to `true` then: (i) when installing libraries, we do not install dynamic foreign archives `dll*.so`; (ii) when building executables in the `byte` mode, we statically link in foreign archives into the runtime system; (iii) we do not generate any `dll*.so` rules. (ocaml/dune#2864, @snowleopard) - Reimplement the bootstrap procedure. The new procedure is faster and should no longer stack overflow (ocaml/dune#2854, @dra27, @diml) - Allow `.opam.template` files to be generated using rules (ocaml/dune#2866, @rgrinberg)
