      Fix subtle bug when checking liveness of module values. · 6355a3ec
      Philipp Stephani authored
      We can't simply look up the Lisp object in the global reference table
      because an invalid local and a valid global reference might refer to
      the same object.  Instead, we have to test the address of the global
      reference against the stored references.

      (value_to_lisp): Use it.

      Port the 'module/async-pipe' test to MS-Windows · f98ee21c
      Eli Zaretskii authored
      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.

      Add a module function to open a file descriptor connected to a pipe. · d28b0047
      Philipp Stephani authored
      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'.

      Fix time-add rounding bug · f9fd12a3
      Paul Eggert authored
      Without this fix, time arithmetic yielded results that were not
      mathematically accurate, even though the exact results were
      representable; for example, (time-add 0 1e-13) yielded a timestamp
      equal to 0 instead of to 1e-13.

      Let time-add do its thing rather than using floating point
      internally, which has rounding errors.  We now have bignums and so

      Add conversions to and from struct timespec to module interface. · bffceab6
      Philipp Stephani authored
      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.

      Properly integrate modules into the loading process (Bug#30164). · 0443411f
      Philipp Stephani authored
      * src/lread.c (Fload): Don't defer to module-load immediately when
      encountering a module, but use the normal loading machinery to
      properly set up load-history, check for recursive loads, print
      messages, etc.
      
      * test/src/emacs-module-tests.el (module/load-history): New test.
      (module/describe-function-1): Adapt test.
      
      * etc/NEWS: Mention fixed behavior.

      This puts functions defined in the module into the 'load-history'.

      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.

      Fix crashing emacs-module tests on MS-Windows · 7fc27ea7
      Eli Zaretskii authored
      * src/w32fns.c (syms_of_w32fns) <w32-disable-abort-dialog>: New
      variable.
      (emacs_abort): If w32-disable-abort-dialog is non-nil, abort right
      away, without displaying the Abort dialog, which waits for the user.
      
      * test/src/emacs-module-tests.el (module--test-assertion): Run the
      inferior Emacs with the w32 abort dialog disabled.  Expect the
      status of the aborted Emacs sub-process to be 3 on MS-Windows and
      2 on MS-DOS.
