Improvements to `diff?` semantics #2486

aalekseyev · 2019-07-31T12:20:02Z

As proposed in #2482, this PR changes the semantics of diff? in two ways:

the first argument becomes a required dependency
the second argument is treated as an intermediate file and is consumed by diff?. It's moved to the .promotion-staging directory where dune promote can still find it.

aalekseyev · 2019-08-02T16:46:37Z

It seems that the change does not require versioning the language because:

it's overwhelmingly common to have the first file be a source file (in ocaml-platform I have not found a single exception from this rule)
It was never supported to use the correction file for anything but promotion (it didn't work as a target, for example). I can't think of no use case that this would break.

Agreed, we should delete this code

Agreed regarding the versioning. We can always revisit if we find a problem at release time, but it's very unlikely.

BTW, we don't delete files from the staging area after promoting them. It feels like we should, what do you think?

…lugin, dune-private-libs and dune-glob (2.0.0+draft1) CHANGES: - Introduce `alias` and `package` fields to the `rule` stanza. This is the preferred way of attaching rules to aliases. (ocaml/dune#2744, @rgrinberg) - Add field `(optional)` for executable stanzas (ocaml/dune#2463, fixes ocaml/dune#2433, @bobot) - Infer targets for rule stanzas expressed in long form (ocaml/dune#2494, fixes ocaml/dune#2469, @NathanReb) - Indicate the progress of the initial file tree loading (ocaml/dune#2459, fixes ocaml/dune#2374, @bobot) - Build `.cm[ox]` files for executables more eagerly. This speeds up builds at the cost of building unnecessary artifacts in some cases. Some of these extra artifacts can fail to built, so this is a breaking change. (ocaml/dune#2268, @rgrinberg) - Do not put the `<package>.install` files in the source tree unless `-p` or `--promote-install-files` is passed on the command line (ocaml/dune#2329, @diml) - Change `implicit_transive_deps` to be false. Implicit transitive deps now must be manually enabled (ocaml/dune#2306, @rgrinberg) - Compilation units of user defined executables are now mangled by default. This is done to prevent the accidental collision with library dependencies of the executable. (ocaml/dune#2364, fixes ocaml/dune#2292, @rgrinberg) - Enable `(explicit_js_mode)` by default. (ocaml/dune#1941, @nojb) - Add an option to clear the console in-between builds with `--terminal-persistence=clear-on-rebuild` - Stop symlinking object files to main directory for stanzas defined `jbuild` files (ocaml/dune#2440, @rgrinberg) - Library names are now validated in a strict fashion. Previously, invalid names would be allowed for unwrapped libraries (ocaml/dune#2442, @rgrinberg) - mli only modules must now be explicitly declared. This was previously a warning and is now an error. (ocaml/dune#2442, @rgrinberg) - Modules filtered out from the module list via the Ordered Set Language must now be actual modules. (ocaml/dune#2442, @rgrinberg) - Actions which introduce targets where new targets are forbidden (e.g. preprocessing) are now an error instead of a warning. (ocaml/dune#2442, @rgrinberg) - No longer install a `jbuilder` binary. (ocaml/dune#2441, @diml) - Stub names are no longer allowed relative paths. This was previously a warning and is now an error (ocaml/dune#2443, @rgrinberg). - Define (paths ...) fields in (context ...) definitions in order to set or extend any PATH-like variable in the context environment. (ocaml/dune#2426, @nojb) - The `diff` action will always normalize newlines before diffing. Perviousy, it would not do this normalization for rules defined in jbuild files. (ocaml/dune#2457, @rgrinberg) - Modules may no longer belong to more than one stanza. This was previously allowed only in stanzas defined in `jbuild` files. (ocaml/dune#2458, @rgrinberg) - Remove support for `jbuild-ignore` files. They have been replaced by the the `dirs` stanza in `dune` files. (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.

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)
