2020-11-28Revert "Fix incorrect handling of module runtime and environment pointers."Eli Zaretskii1-10/+0
This reverts commit cdc632fbe6e149318147a98cccf1b7af191f2ce8. Those changes are too significant and non-trivial to be suitable for a release branch at this time.
2020-11-27Fix incorrect handling of module runtime and environment pointers.Philipp Stephani1-0/+10
We used to store module runtime and environment pointers in the static lists Vmodule_runtimes and Vmodule_environments. However, this is incorrect because these objects have to be kept per-thread. With this naive approach, interleaving module function calls in separate threads leads to environments being removed in the wrong order, which in turn can cause local module values to be incorrectly garbage-collected. Instead, turn Vmodule_runtimes and Vmodule_environments into hashtables keyed by the thread objects. The fix is relatively localized and should therefore be safe enough for the release branch. Module assertions now have to walk the pointer list for the current thread, which is more correct since they now only find environments for the current thread. Also add a unit test that exemplifies the problem. It interleaves two module calls in two threads so that the first call ends while the second one is still active. Without this change, this test triggers an assertion failure. * src/emacs-module.c (Fmodule_load, initialize_environment) (finalize_environment, finalize_runtime_unwind): Store runtime and environment pointers in per-thread lists. (syms_of_module): Initialize runtimes and environments hashtables. (module_assert_runtime, module_assert_env, value_to_lisp): Consider only objects for the current thread. (module_gc_hash_table_size, module_hash_push, module_hash_pop): New generic hashtable helper functions.

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.

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.

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.
2019-11-26* test/lisp/minibuffer-tests.el (completion-table-test-quoting): New testStefan Monnier1-0/+0
* test/data/minibuffer-test-cttq$tion: New file-name test data.
2019-09-21Add an Exif parsing libraryLars Ingebrigtsen1-0/+0
* lisp/image/exif.el: New file (bug#23070). * test/lisp/image/exif-tests.el: Add some basic tests.
2019-05-05Port mod-test to --enable-gcc-warningsPaul Eggert1-0/+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.
2019-05-05Fix compilation of mod-test.c on MinGWEli Zaretskii1-0/+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.
2019-05-05Use extract_time in test module.Philipp Stephani1-17/+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’.
2019-04-28Export major version of latest Emacs supported by emacs-module.h.Philipp Stephani1-0/+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.
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. ($(test_module)): Use them. * test/data/emacs-module/mod-test.c: Use mini-gmp if GMP is unavailable.
2019-04-24Clarify rounding mode when converting to struct timespec.Philipp Stephani1-0/+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.
2019-04-24Add module functions to convert from and to big integers.Philipp Stephani1-0/+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.
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. (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.
