2020-03-27Port the 'module/async-pipe' test to MS-WindowsEli Zaretskii1-7/+41
These changes let the code compile and produce a valid DLL, but the test hangs. It looks like the hang is in Fdelete_process, when it closes one of the descriptors of the pipe process. In addition, this use of the pipe process cannot currently work on MS-Windows, since make-pipe-process doesn't set up the reader thread to read from the Emacs's side of the pipe, so the select emulation doesn't know there's stuff to read from that pipe. * test/data/emacs-module/mod-test.c [WINDOWSNT]: Include windows.h. (ALIGN_STACK) [!__x86_64__]: Define for 32-bit builds. (sleep_for_half_second): New function. (write_to_pipe): Declare return type differently for WINDOWSNT. Call sleep_for_half_second. (Fmod_test_async_pipe) [WINDOWSNT]: Use _beginthread as substitute for pthread_create. (invalid_finalizer): Replace non_ASCII character in a comment. * test/src/emacs-module-tests.el (module/async-pipe): Skip on MS-Windows, as the test fails and then hangs.
2020-03-26Add a module function to open a file descriptor connected to a pipe.Philipp Stephani1-2/+55
A common complaint about the module API is that modules can't communicate asynchronously with Emacs. While it isn't possible to call arbitrary Emacs functions asynchronously, writing to a pipe should always be fine and is a pretty low-hanging fruit. This patch implements a function that adapts an existing pipe process. That way, users can use familiar tools like process filters or 'accept-process-output'. * src/module-env-28.h: Add 'open_channel' module function. * src/emacs-module.c (module_open_channel): Provide definition for 'open_channel'. (initialize_environment): Use it. * src/process.c (open_channel_for_module): New helper function.

(signal_errno): Use it. (write_to_pipe): New function running in the background. (Fmod_test_async_pipe): New test module function. (emacs_module_init): Export it. * doc/lispref/internals.texi (Module Misc): Document new module function. * doc/lispref/processes.texi (Asynchronous Processes): New anchor for pipe processes. * etc/NEWS: Document 'open_channel' function.

2020-01-05Also print function data when printing module functions.Philipp Stephani1-1/+4
This is especially useful in cases where modules only use a single entry point and use the data to dispatch to the actual function. Such a design is common for languages such as Go and C++. * src/emacs-module.c (module_function_data): New function. * src/print.c (print_vectorlike): Use it to print module function data if not NULL.

2019-12-04Change module interface to no longer use GMP objects directly.Philipp Stephani1-14/+97
As described in the new comment added to emacs-module.c, using GMP directly in the module interface has significant downsides: it couples the module interface directly to the implementation and requires module authors to link their module against the same GMP library as Emacs itself, which is often difficult and an unnecessary burden. By picking a representation for the magnitude that often matches the one used by GMP, we can avoid overhead when converting from and to GMP in most cases. Loading the test module in test/data/emacs-module and evaluating (dotimes (_ 10000) (mod-test-double (* 2 most-negative-fixnum))) under Callgrind shows that on my (GNU/Linux) machine Emacs only spends 10% of the CPU time of mod-test-double in mpz_import and mpz_export combined, even though that function does little else. (By contrast, 30% is spent in allocate_pseudovector.) * src/emacs-module.h.in: Don't check EMACS_MODULE_GMP. Don't include gmp.h. Remove emacs_mpz structure. Instead, define type alias emacs_limb_t and macro EMACS_LIMB_MAX. * src/module-env-27.h: Change interface of extract_big_integer and make_big_integer to take a sign-magnitude representation instead of mpz_t. * src/emacs-module.c: Don't check EMACS_MODULE_GMP or EMACS_MODULE_HAVE_MPZ_T. Add a comment about the chosen implementation. (module_extract_big_integer, module_make_big_integer): Reimplement without using mpz_t in the interface. * doc/lispref/internals.texi (Module Values): Adapt function documentation and example. Stop mentioning GMP and EMACS_MODULE_GMP. * test/data/emacs-module/mod-test.c: Don't define EMACS_MODULE_GMP or EMACS_MODULE_HAVE_MPZ_T. (memory_full, extract_big_integer, make_big_integer): New helper functions, identical to example in the Info documentation. (Fmod_test_nanoseconds, Fmod_test_double): Adapt to new interface.

2019-04-24Unbreak build when building without GMP support.Philipp Stephani1-2/+7
Add support for a new preprocessor macro EMACS_MODULE_HAVE_MPZ_T to emacs-module.h. If this macro is defined, assume that mpz_t is already defined and don’t include gmp.h. Don’t document the new macro for now, as it’s unclear whether we want to support this in modules outside the Emacs tree. * src/emacs-module.h.in: Allow user to prevent inclusion of gmp.h. * src/emacs-module.c: Use mini-gmp if GMP is unavailable. Don’t include gmp.h. * src/lisp.h: Don’t require gmp.h. It’s not needed for lisp.h. * test/Makefile.in (GMP_LIB, GMP_OBJ): New variables.

2019-04-24Add conversions to and from struct timespec to module interface.Philipp Stephani1-0/+13
Time values are a fundamental data type, and such conversions are hard to implement within modules because of the various forms of time values in Emacs Lisp. Adding dedicated conversion functions can significantly simplify module code dealing with times. This approach uses nanosecond precision. While Emacs in theory has support for higher-precision time values, in practice most languages and standards, such as POSIX, C, Java, and Go, have settled on nanosecond-precision integers to represent time. * src/emacs-module.h.in: Add header for struct timespec. * src/module-env-27.h: Add module functions for time conversion. * src/emacs-module.c (module_extract_time, module_make_time): New functions.

2019-02-24Ignore pending_signals when checking for quits.Philipp Stephani1-1/+68
pending_signals is often set if no quit is pending. This results in bugs in module code if the module returns but no quit is actually pending.

2017-09-13Prefer HTTPS to FTP and HTTP in documentationPaul Eggert1-1/+1
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.

It's technically possible to write a user pointer finalizer that calls into Emacs module functions.

2017-06-12Implement module assertions for usersPhilipp Stephani1-0/+24
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.
