| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of doing GMP by hand, use the Gnulib libgmp module. * .gitignore: Add lib/gmp.h. * admin/merge-gnulib (GNULIB_MODULES): Add libgmp. * configure.ac (GMP_LIB, GMP_OBJ): Remove. Gnulib uses the name LIB_GMP, so all uses changed. All uses of GMP_OBJ removed. (HAVE_GMP): Set this from Gnulib’s variables. * lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate. * lib/mini-gmp-gnulib.c, lib/mini-gmp.c, lib/mini-gmp.h, m4/libgmp.m4: New files, copied from Gnulib. * src/bignum.h, test/data/emacs-module/mod-test.c: Include gmp.h unconditionally. * src/mini-gmp-emacs.c, src/mini-gmp.c, src/mini-gmp.h: Remove. This moves these files from src to lib, and updates them to the current GMP version. * test/Makefile.in (GMP_H): New macro. ($(test_module)): Use it to decide whether to compile mini-gmp-gnulib.c too.
* | Port the 'module/async-pipe' test to MS-WindowsEli Zaretskii2020-03-271-7/+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.
* | Add a module function to open a file descriptor connected to a pipe.Philipp Stephani2020-03-261-2/+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.

* | Also print function data when printing module functions.Philipp Stephani2020-01-051-1/+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. (print_object): Adapt size of buffer. * test/data/emacs-module/mod-test.c (emacs_module_init): Pass some non-NULL data to ‘mod-test-sum’. (Fmod_test_sum): Check that correct data is passed through. * test/src/emacs-module-tests.el (mod-test-sum-test) (module-function-object): Adapt unit tests.

* Change module interface to no longer use GMP objects directly.Philipp Stephani2019-12-041-14/+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.
* * test/lisp/minibuffer-tests.el (completion-table-test-quoting): New testStefan Monnier2019-11-261-0/+0
| | | | * test/data/minibuffer-test-cttq$tion: New file-name test data.
* Add an Exif parsing libraryLars Ingebrigtsen2019-09-211-0/+0
| | | | | | * lisp/image/exif.el: New file (bug#23070). * test/lisp/image/exif-tests.el: Add some basic tests.
* Port mod-test to --enable-gcc-warningsPaul Eggert2019-05-051-0/+2
| | | | | | * test/data/emacs-module/mod-test.c (NDEBUG): Undef, to prevent GCC from complaining “error: unused variable ‘dummy’” and failing to build the test, if --enable-gcc-warnings.
* Fix compilation of mod-test.c on MinGWEli Zaretskii2019-05-051-0/+4
| | | | | | * test/data/emacs-module/mod-test.c (Fmod_test_nanoseconds) [__MINGW32__]: Use _Static_assert, not static_assert, as the latter is not available in mingw.org's MinGW's assert.h.
* Use extract_time in test module.Philipp Stephani2019-05-051-17/+1
| | | | | | | | | * test/data/emacs-module/mod-test.c (Fmod_test_sleep_until): Use extract_time for time argument. (signal_wrong_type_argument): Remove unused function. * test/src/emacs-module-tests.el (mod-test-sleep-until): Remove unnecessary ‘float-time’.
* Export major version of latest Emacs supported by emacs-module.h.Philipp Stephani2019-04-281-0/+5
| | | | | | | | | | | | | | | This is useful if module authors want to support multiple versions of emacs-module.h. * configure.ac (emacs_major_version): Define substitution. * src/emacs-module.h.in (EMACS_MAJOR_VERSION): Define macro. * doc/lispref/internals.texi (Module Initialization): Document EMACS_MAJOR_VERSION preprocessor macro. * test/data/emacs-module/mod-test.c (emacs_module_init): Verify behavior of EMACS_MAJOR_VERSION.
* Unbreak build when building without GMP support.Philipp Stephani2019-04-241-2/+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. ($(test_module)): Use them. * test/data/emacs-module/mod-test.c: Use mini-gmp if GMP is unavailable.
* Clarify rounding mode when converting to struct timespec.Philipp Stephani2019-04-241-0/+17
| | | | | | | | | | | * doc/lispref/internals.texi (Module Values): Clarify that the truncation is towards negative infinity. * test/data/emacs-module/mod-test.c (Fmod_test_nanoseconds): Add test function. (emacs_module_init): Define it. * test/src/emacs-module-tests.el (mod-test-nanoseconds): New unit test.
* Add module functions to convert from and to big integers.Philipp Stephani2019-04-241-0/+19
| | | | | | | | | | | | | | | | | | | * src/module-env-27.h: Add new module functions to convert big integers. * src/emacs-module.h.in (emacs_mpz): Define if GMP is available. * src/emacs-module.c (module_extract_big_integer) (module_make_big_integer): New functions. (initialize_environment): Use them. * test/data/emacs-module/mod-test.c (Fmod_test_double): New test function. (emacs_module_init): Define it. * test/src/emacs-module-tests.el (mod-test-double): New unit test. * doc/lispref/internals.texi (Module Values): Document new functions.
* Add conversions to and from struct timespec to module interface.Philipp Stephani2019-04-241-0/+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. (initialize_environment): Use them. * test/data/emacs-module/mod-test.c (Fmod_test_add_nanosecond): New test function. (emacs_module_init): Define it. * test/src/emacs-module-tests.el (mod-test-add-nanosecond/valid) (mod-test-add-nanosecond/nil, mod-test-add-nanosecond/invalid): New unit tests. * doc/lispref/internals.texi (Module Values): Document time conversion functions.
