Mangle compilation units of dune generated modules #2364

rgrinberg · 2019-07-05T10:44:22Z

As discussed, we want to minimize the chance of compilation units of libraries colliding with the executables. For dune generated exe's (as opposed to user defined ones), I think we can change the scheme unilaterally without the user noticing.

I've opted for some fairly simple mangling for these modules. Just to make sure we don't introduce unnecessary recompilation.

rgrinberg · 2019-07-07T10:10:18Z

@diml I've added a slightly simpler name mangling scheme based on the project name and the source dir. This seems safe enough and is friendlier to incremental compilation. Also, we don't need the linking closure to just compute the module names of executables.

Agreed for not using the closed list of modules. Though using the project name feels a bit odd. In particular, as we discussed recently in another PR it's possible that we'll allow project names to not be unique at some point.

As long as we have __ in the prefix, this would only break if someone was using __ in a library name, which is very unlikely. What about always using dune__exe as prefix? Or bin__prefix (this is similar to what we use inside Jane Street).

Another point I just thought of: it's nice if the full object name is easily predictable as one has to deal with such names when debugging with gdb.

Indeed, but otherwise I'm not really sure what's a good name for alias modules which are shared between executables. Note that the project name is mainly added for debugging rather than uniqueness.

ghost · 2019-07-08T10:43:27Z

I suppose we could just use Bin__prefix__, just as for libraries.

Are you thinking of gdb debugging BTW? i.e. that including the project name will help determine what executable we are talking about when debugging with gdb?

Yup. Otherwise, all alias modules for executables are going to look quite generic.

ghost · 2019-07-08T11:00:38Z

Is that an issue though? You can't have two such sets in a gdb session.

rgrinberg · 2019-07-08T11:20:33Z

I suppose that's true. I'll get rid of it if you prefer that.

ghost · 2019-07-08T11:52:27Z

I prefer that, yeah. Let's keep things as simple as possible unless we really need the complexity.

Looks good. We do need a changelog entry though

rgrinberg · 2019-07-08T13:58:50Z

Simplifying the name mangling reveals a new problem:

When we have multiple executables in one directory, we attempt to generate the alias file twice. Wondering how to best address this. A couple of simple options:

Memoize the function which generates the rule for the alias file
Generate the alias source in the object directory

rgrinberg · 2019-07-08T14:25:03Z

I've renamed the option to wrapped_executables. I don't believe that we're using abbreviations in the project file currently. Might as well not start now.

ghost · 2019-07-08T15:21:08Z

What about generating the alias file in the object directory?

Executables generated by dune are mangled by default. Executables that are written by the user are mangled starting from 2.0. The user can turn off this option per project with the `wrapped_exes` option. Signed-off-by: Rudi Grinberg <rudi.grinberg@gmail.com>

Previously, we'd attempt to generate the rules for the alias module twice. Now we just generate the alias module in the object directory. Signed-off-by: Rudi Grinberg <rudi.grinberg@gmail.com>

Signed-off-by: Rudi Grinberg <rudi.grinberg@gmail.com>

If an executable has only a single module then it doesn't need wrapping. This saves us from generating and compiling a single source file. Signed-off-by: Rudi Grinberg <rudi.grinberg@gmail.com>

What about generating the alias file in the object directory?

I ended up doing that. But I'm not really liking this solution as we end up generating the same source multiple times. I think it would be better if simply memoized the generation rules.

A couple of other minor fixed I did:

The alias module is unnecessary for executables with only a single module.
.merlin files are now correctly generated for mangled executables

And I've also enabled this mode in dune itself. Let's make sure it doesn't introduce any problems in our workflow before releasing to the public.

ghost · 2019-07-09T07:19:02Z

Why do we generate the same source multiple times? Is it in the case where we have several executable stanzas in the same dune file?

And I've also enabled this mode in dune itself. Let's make sure it doesn't introduce any problems in our workflow before releasing to the public.

That's a good idea!

rgrinberg · 2019-07-09T08:21:03Z

Yup

ghost · 2019-07-09T09:44:09Z

But aren't the sources different in such case?

rgrinberg · 2019-07-09T10:33:07Z

But aren't the sources different in such case?

Hmm, good question. I recall considering this before. IIRC, I wanted to generate a single alias module as it would be quite annoying to need the top closure of every executable before generating the alias module. For some reason I thought that it shoudld still be possible to link in an alias module if we don't have an implementation for every module it references. This seems to work I think

ghost · 2019-07-09T11:03:38Z

Yep, that works fine. What we want is to have a single alias module per executable or executables stanza. However, we don't want to share the alias module between different stanzas as that seems like unnecessary complication for minimal gain.

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.

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#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. (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)

Fix alias module of multi exes in same dir

f958f53

Previously, we'd attempt to generate the rules for the alias module twice. Now we just generate the alias module in the object directory. Signed-off-by: Rudi Grinberg <rudi.grinberg@gmail.com>

Simplify wrapping of 1 module exes

f3fdaae

If an executable has only a single module then it doesn't need wrapping. This saves us from generating and compiling a single source file. Signed-off-by: Rudi Grinberg <rudi.grinberg@gmail.com>
