package ocaml_plugin

v0.11

• Rework the API of Ocaml_plugin to use the new stdless idiom. (Keep the old one as deprecated) Also, the following modules were renamed:

  • Ocaml_plugin.Std.Ocaml_dynloader is now accessible at Ocaml_plugin.Dynloader

  • Ocaml_plugin.Std.Ocaml_compiler is now accessible at Ocaml_plugin.Compiler

113.43.00

• In Ocaml_plugin, drop t_of_sexp on an unstable type not meant to expose this. This was most probably added either temporarily or maybe by mistake.

• Allow the specification of the permissions with which to create in_dir (the directory where ocaml_plugin does its compilation).

• If a persistent compiler archive is modified, ocaml_plugin will probably fail at compiling. Make it more robust by considering the archive invalid instead. This can easily happen when deleting a bunch of cmi/cmx/exe recursively and inadvertently messing up the ocaml_plugin archive.

  On the way, I simplify things by passing more information from ocaml_embed_compiler (at compile time) to ocaml_plugin (at runtime) without having to look in the archive.

113.33.00

• Improve the check plugin command that comes with ocaml-plugin:

  1. Improve documentation, add readme to include more info about what is being checked exactly.

  2. Avoid the switch -code-style _ for application that have made a choice of code style statically. Having the swtich available at runtime is just confusing, since only 1 style is going to work anyway.

113.24.02

• Added an ocamlbuild plugin to ease the creation of embed programs

113.24.00

• Switch to ppx.

• Allow ppx-style code to be loaded by plugin-applications build using ocaml_plugin.

• Follow Core & Async evolution.

113.00.00

• Made Ocaml_plugin.Plugin_cache.Config.t stable.

112.35.00

• In copy_source_files_to_working_dir, exclude files that start with a dot.

  emacs creates temporary files that cannot be read with names like .#foo.ml, and attempting to copy those causes this function to fail.

112.24.00

Minor update: follow Async evolution.

112.17.00

• Fixed spurious interface mismatch error when a plugin cache is shared by incompatible compilers.

  When a plugin cache directory is used by several executables with incompatible cmis/compilers, and the cache config option try_old_cache_with_new_exec is set to true, this could lead to the following error:

  Plugin failed: (ocaml_dynloader.ml.Dynlink_error "interface mismatch")
  

  This feature fixes this.

  Since it modifies some record, for later changes it seems easier and more conservative to allow field additions without breaking older version. Thus we allow extra fields in persisted records.

  let t_of_sexp = Sexp.of_sexp_allow_extra_fields t_of_sexp
  

  New executables can read both old and new caches, but old executables will either blow away new caches, or if the config says the cache is read-only, fail.

  Take the chance to modernize part of the code.

• Switched tests to unified tests.

• Fixed bugs dealing with paths with spaces in them.

• Check that plugins have the expected type before running them rather than after, which is what one would expect.

  Also check that runtime and compile types match in check_ocaml_src_files and compile_ocaml_src_files_into_cmxs_file.

112.06.00

• Stopped using the ~exclusive with Reader, because it doesn't work on read-only file systems.

  It's not even needed because these files are written atomically.

• Used a generative functor in the generated code, so the user code can apply generative functors at toplevel, or unpack first class modules that contain type components.

• Fixed bug when mli file references something defined only in another ml.

• Made it possible to compile a plugin in one process, and dynload the compiled cmxs file without starting async in another process.

  This was done with two new APIs in Ocaml_dynloader.S:

    val compile_ocaml_src_files_into_cmxs_file
      : dynloader
      -> string list
      -> output_file:string
      -> unit Deferred.Or_error.t
  
    val blocking_load_cmxs_file : string -> t Or_error.t
  

• Allowed plugins to optionally have a shebang line.

• Made Ocaml_dynloader.find_dependencies also support files with shebang lines.

112.01.00

• Changed to not use rm -r when it is expected to remove one file.

111.28.00

• Fixed a bug in tests that could leave the repository in a state where running the tests would fail.

  The bug happened if the tests were interrupted after creating read-only directories but before cleaning then up.

111.25.00

• ignore more warnings by default

111.21.00

• Fixed a bug in ocaml_embed_compiler on 32-bit machines.

  ocaml_embed_compiler tries to read the full contents of the file as a string, but the string might be too big on 32bits:

111.11.00

• Added a tag to exceptions coming from the toplevel execution of plugins so that we do not confuse them with exceptions coming from the library.

  Also, added a function to check a plugin without executing it. And captured the common pattern of checking the compilation of a plugin in a Command.t offered in the library.

111.08.00

• Use ocamldep to generate the dependencies of an .ml file, if requested.

  Added a function to find the dependencies of a module, but did not change the existing behavior and interface of the library if one does not choose to use this functionality.

110.01.00

• Added cmi's so that plugins can use lazy, recursive modules, and objects.

109.53.00

Bump version number

109.45.00

• Made executables link without error even if no archive is embedded in them.

  This is often the desired behavior (for inline tests of libraries using transitively ocaml-plugin for instance).

109.41.00

• Added option -strict-sequence, which is set to true by default.

109.35.00

• Changed the execution of plugin's toplevel to run in async instead of In_thread.run, unless a config parameter says otherwise.

109.32.00

• Fixed the slow and memory-consuming compilation of > 100MB .c files generated by ocaml_embed_compiler.

  This was done by having them contain one big string instead of one big array.

• Added more unused-value warnings in plugins.

  If { Ui , M } are the modules that constitute a given plugin of expected module type S, then previously we generated a file like:

  module Ui : sig
    ...
  end = struct
    ...
  end
  
  module M : sig
    ...
  end = struct
    ...
  end
  
  let () = ##register (M : S)
  

  Doing that, we did not get unused variables:

  1. for the toplevel of Ui if Ui does not have a mli.

  2. for unused values of Ui and M if they have an mli exporting them.

  OCaml plugin now allows one to get these warnings. Since (2) is rather annoying for utils kind of file, this comes only if a config flag is enabled.

109.31.00

• Fixed OCaml Plugin on CentOS 5 -- it had problems because the generated c files did not end with a newline.

• Finished the transition from Command_deprecated to Command.

109.30.00

• Support for Mac OSX

  Removed the dependency of ocaml-plugin on objcopy and /proc.

109.20.00

• Removed a test that (rarely) failed nondeterministically.
