      Prefer HTTPS to FTP and HTTP in documentation · bc511a64
      Paul Eggert authored
      Most of this change is to boilerplate commentary such as license URLs.
      This change was prompted by ftp://ftp.gnu.org's going-away party,
      planned for November.  Change these FTP URLs to https://ftp.gnu.org
      instead.  Make similar changes for URLs to other organizations moving
      away from FTP.  Also, change HTTP to HTTPS for URLs to gnu.org and
      fsf.org when this works, as this will further help defend against
      man-in-the-middle attacks (for this part I omitted the MS-DOS and
      MS-Windows sources and the test tarballs to keep the workload down).
      HTTPS is not fully working to lists.gnu.org so I left those URLs alone
      for now.

      Module assertions: check for garbage collections · b7dab24b
      Philipp Stephani authored
      It's technically possible to write a user pointer finalizer that calls
      into Emacs module functions.  This would be disastrous because it
      would allow arbitrary Lisp code to run during garbage collection.
      Therefore extend the module assertions to check for this case.
      
      * src/emacs-module.c (module_assert_thread): Also check whether a
      garbage collection is in progress.
      
      * test/data/emacs-module/mod-test.c (invalid_finalizer)
      (Fmod_test_invalid_finalizer): New test module functions.
      (emacs_module_init): Register new test function.

      (module--with-temp-directory): New helper macros.
      (module--test-assertions--load-non-live-object): Rename existing

      Implement module assertions for users · cf971327
      Philipp Stephani authored
      Add a new command-line option '-module-assertions' that users can
      enable developing or debugging a module.  If this option is present,
      Emacs performs additional checks to verify that modules fulfill their
      requirements.  These checks are expensive and crash Emacs if modules
      are invalid, so disable them by default.
      
      This is a command-line option instead of an ordinary variable because
      changing it while Emacs is running would cause data structure
      imbalances.
      
      * src/emacs.c (main): New command line option '-module-assertions'.
      
      * src/emacs-module.c (module_assert_main_thread)
      (module_assert_runtime, module_assert_env, module_assert_value):
      New functions to assert module requirements.
      (syms_of_module): New uninterned variable 'module-runtimes'.
      (init_module_assertions, in_main_thread, module_abort): New helper
      functions.
      (initialize_environment): Initialize value list.  If assertions are
      enabled, use a heap-allocated environment object.
      (finalize_environment): Add assertion that environment list is never
      empty.
      (finalize_runtime_unwind): Pop module runtime object stack.
      (value_to_lisp): Assert that the value is valid.
      (lisp_to_value): Record new value if assertions are enabled.
      (mark_modules): Mark allocated object list.
      (MODULE_FUNCTION_BEGIN_NO_CATCH)
      (module_non_local_exit_check, module_non_local_exit_clear)
      (module_non_local_exit_get, module_non_local_exit_signal)
      (module_non_local_exit_throw): Assert thread and environment.
      (module_get_environment): Assert thread and runtime.

      (module_funcall, module_make_integer, module_make_float)
      (module_make_string, module_make_user_ptr, module_vec_get)
      (funcall_module, Fmodule_load): Adapt callers.
      (module_make_global_ref): If assertions are enabled, use the global
      environment to store global values.
      (module_free_global_ref): Remove value from global value list.
      
      * test/Makefile.in (EMACSOPT): Enable module assertions when testing
      modules.
      
      * test/data/emacs-module/mod-test.c (Fmod_test_invalid_store)

      the Emacs binary file.

      Rework printing of module functions · 3b0080de
      Philipp Stephani authored
      Fix a FIXME in emacs-module.c.  Put the printing into print.c, like
      other types.
      
      * src/print.c (print_vectorlike): Add code to print module functions.
      
      * src/emacs-module.c (funcall_module): Stop calling

      objects, they can be added to signal data directly.
      (module_handle_signal): Remove now-unused function
      'module_format_fun_env'.
      
      * test/src/emacs-module-tests.el (mod-test-sum-test): Adapt unit test.

      Reimplement module functions · 31fded03
      Philipp Stephani authored
      Instead of a lambda, create a new type containing all data required to
      call the function, and support it in the evaluator.  Because this type
      now also needs to store the function documentation, it is too big for
      Lisp_Misc; use a pseudovector instead.  That also has the nice benefit
      that we don't have to add special support to the garbage collector.
      
      Since the new type is user-visible, give it a predicate.
      
      Now we can easily support 'help-function-args' and 'func-arity'; add
      unit tests for these.
      
      * src/lisp.h (allocate_module_function, MODULE_FUNCTIONP)
      (XMODULE_FUNCTION): New pseudovector type 'module function'.
      
      * src/eval.c (FUNCTIONP): Also treat module functions as functions.
      (funcall_lambda, Ffuncall, eval_sub): Add support for calling module
      functions.
      (Ffunc_arity): Add support for detecting the arity of module
      functions.
      
      * src/emacs-module.c (module_make_function): Adapt to new structure.
      Return module function object directly instead of wrapping it in a
      lambda; remove FIXME.
      (funcall_module): New function to call module functions.  Replaces
      `internal--module-call' and is called directly from eval.c.
      (syms_of_module): Remove internal helper function, which is no longer
      needed.
      (module_function_arity): New helper function.
      
      * src/data.c (Ftype_of): Adapt to new implementation.
      (Fmodule_function_p, syms_of_data): New user-visible function.  Now
      that module functions are first-class objects, they deserve a
      predicate.  Define it even if not compiled with --enable-modules so
      that Lisp code doesn't have to check for the function's existence.
      
      * src/doc.c (Fdocumentation): Support module functions.
      
      * src/print.c (print_object): Adapt to new implementation.
      
      * src/alloc.c (mark_object): Specialized garbage collector support is
      no longer needed.
      
      * lisp/help.el (help-function-arglist): Support module functions.
      While there, simplify the arity calculation by using `func-arity',
      which does the right thing for all kinds of functions.
      
      * test/data/emacs-module/mod-test.c: Amend docstring so we can test
      the argument list.
      
      * test/src/emacs-module-tests.el (mod-test-sum-docstring): Adapt to
      new docstring.
      (mod-test-non-local-exit-signal-test): Because `internal--module-call'
      is gone, the backtrace has changed and no longer leaks the
      implementation.
      (module--func-arity): New test for `func-arity'.
      (module--help-function-arglist): New test for `help-function-arglist'.
