      Use alignas to fix GCALIGN-related bugs · b1573a97
      Paul Eggert authored
      Use alignas and unions to specify alignments of objects needing
      addresses that are at least a multiple of GCALIGNMENT.  Using
      these standard C facilities should be safer than relying on ad hoc
      and poorly-understood features like GCC’s __attribute__
      ((aligned (N))), the root cause for recent porting bugs like
      Bug#29040.  The alignas macro was standardized by C11 and Gnulib
      supports alignas for pre-C11 platforms.  I have tested this on Sun
      Studio 12 sparc (2007) and GCC 4.4.7 x86-64 (2012) as well as on
      more recent platforms like GCC 7.2.1 (2017) on Fedora 26 (both
      x86-64 and x86).
      * lib-src/make-docfile.c (close_emacs_globals): lispsym is now
      just an array of struct Lisp_Symbol, since struct Lisp_Symbol is
      now properly aligned.  All uses changed.
      * src/alloc.c (NEXT_FREE_LISP_STRING): Just use the new u.next
      member; this is simpler and safer than casting a pointer that
      might not be aligned properly.
      (aligned_Lisp_Symbol): Remove.  No longer needed, now that struct
      Lisp_Symbol is aligned properly.  All uses replaced with struct
      Lisp_Symbol.
      * src/lisp.h (GCALIGNED): Remove, as it does not work as expected:
      it can cause the natural alignment to be ignored.  All uses
      replaced by unions with a ‘char alignas (GCALIGNMENT)’ member as
      described below.
      (struct Lisp_Symbol, struct Lisp_Cons, struct Lisp_String):
      Change definition from ‘struct TAG { MEMBERS };’ to
      ‘struct TAG { union { struct { MEMBERS } s; char alignas
      (GCALIGNMENT) gcaligned; } u; };’.  This guarantees ‘struct TAG’
      to have an alignment that at least max (GCALIGNMENT, N) where N is
      its old alignment.  All uses like ‘PTR->MEMBER’ changed to
      ‘PTR->u.s.MEMBER’; these uses were supposed to be mostly private
      anyway.  Verify that the resulting ‘struct TAG’ is properly
      aligned for Emacs.
      (union vectorlike_header): New member ‘gcaligned’ to guarantee
      that this type, and its containing types like ‘struct Lisp_Subr’,
      ‘struct buffer’ and ‘struct thread_state’, are all properly
      aligned for Emacs.
      (struct Lisp_String): New union member ‘next’, for the benefit
      of NEXT_FREE_LISP_STRING.
      (union Aligned_Cons, union Aligned_String): Remove.  All uses
      replaced by struct Lisp_Cons and struct Lisp_String, since they
      are now properly aligned.
      (USE_STACK_CONS, USE_STACK_STRING): Simplify now that we can
      assume struct Lisp_Cons and struct Lisp_String are properly
      aligned.

      Tweak Fdocumentation's error for an undefined function · 6a00914d
      Glenn Morris authored
      * src/doc.c (Fdocumentation): Restore the pre-25 behavior
      of signalling a void-function error for an undefined function.
      This seems cleaner than Emacs 25's "invalid-function: nil" error,

      Findirect_function.

      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.

      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'.

      Revamp quitting and fix infloops · b01ac672
      Paul Eggert authored
      This fixes some infinite loops that cannot be quitted out of,
      e.g., (defun foo () (nth most-positive-fixnum '#1=(1 . #1#)))
      when byte-compiled and when run under X.  See:
      http://lists.gnu.org/archive/html/emacs-devel/2017-01/msg00577.html
      This also attempts to keep the performance improvements I recently
      added, as much as possible under the constraint that the infloops
      must be caught.  In some cases this fixes infloop bugs recently
      introduced when I removed immediate_quit.
      * src/alloc.c (Fmake_list):
      Use rarely_quit, not maybe_quit, for speed in the usual case.
      * src/bytecode.c (exec_byte_code):
      * src/editfns.c (Fcompare_buffer_substrings):
      * src/fns.c (Fnthcdr):
      * src/syntax.c (scan_words, skip_chars, skip_syntaxes)
      (Fbackward_prefix_chars):
      Use rarely_quit so that users can C-g out of long loops.
      * src/callproc.c (call_process_cleanup, call_process):
      * src/fileio.c (read_non_regular, Finsert_file_contents):
      * src/indent.c (compute_motion):
      * src/syntax.c (scan_words, Fforward_comment):

      * src/fileio.c (Fcopy_file, read_non_regular, Finsert_file_contents):
      * src/lread.c (safe_to_load_version):
      * src/sysdep.c (system_process_attributes) [GNU_LINUX]:
      Use emacs_read_quit instead of emacs_read in places where
      C-g handling is safe.
      * src/eval.c (maybe_quit): Move comment here from lisp.h.
      * src/fileio.c (Fcopy_file, e_write):
      Use emacs_write_quit instead of emacs_write_sig in places where
      C-g handling is safe.
      * src/filelock.c (create_lock_file): Use emacs_write, not
      plain write, as emacs_write no longer has a problem.
      (read_lock_data): Use emacs_read, not read, as emacs_read
      no longer has a problem.
      * src/fns.c (rarely_quit): Move to lisp.h and rename to
      incr_rarely_quit.  All uses changed..
      * src/fns.c (Fmemq, Fmemql, Fassq, Frassq, Fplist_put, Fplist_member):
      * src/indent.c (compute_motion):
      * src/syntax.c (find_defun_start, back_comment, forw_comment)
      (Fforward_comment, scan_lists, scan_sexps_forward):
      Use incr_rarely_quit so that users can C-g out of long loops.
      * src/fns.c (Fnconc): Move incr_rarely_quit call to within
      inner loop, so that it catches C-g there too.
      * src/keyboard.c (tty_read_avail_input): Remove commented-out
      and now-obsolete code dealing with interrupts.
      * src/lisp.h (rarely_quit, incr_rarely_quit): New functions,
      the latter moved here from fns.c and renamed from rarely_quit.
      (emacs_read_quit, emacs_write_quit): New decls.
      * src/search.c (find_newline, search_buffer, find_newline1):
      Add maybe_quit to catch C-g.
      * src/sysdep.c (get_child_status): Always invoke maybe_quit
      if interruptible, so that the caller need not bother.
      (emacs_nointr_read, emacs_read_quit, emacs_write_quit):
      New functions.
      (emacs_read): Rewrite in terms of emacs_nointr_read.
      Do not handle C-g or signals; that is now for emacs_read_quit.
      (emacs_full_write): Replace PROCESS_SIGNALS two-way arg
      with INTERRUPTIBLE three-way arg.  All uses changed.

      but does not include it directly.  As a general rule, a source
      file should include foo.h if it needs the interfaces that foo.h
      defines.

      Omit unnecessary \ before paren in C docstrings · 032ce1c7
      Paul Eggert authored
      Although \( is needed in docstrings in Elisp code, it is not needed in
      docstrings in C code, since C function definitiions do not start with
      a parenthesis.  The backslashes made the docstrings a bit harder to
      read and to format in columns.  Also, some C docstrings had ( in
      column 1 and this did not appear to be causing any problems.  So,
      simplify C docstrings by replacing \( with ( and \) with ).

      Go back to grave quoting in source-code docstrings etc. · 6afef3f6
      Paul Eggert authored
      This reverts almost all my recent changes to use curved quotes
      in docstrings and/or strings used for error diagnostics.
      There are a few exceptions, e.g., Bahá’í proper names.

      This means we no longer need %qs, so remove that format.
      While we’re at it, fix an unlikely bug and lessen the pressure

      (Fsubstitute_command_keys): Prefer AUTO_STRING to build_string
      when pure ASCII now suffices.  Fix unlikely bug when parsing
      unibyte string containing non-ASCII bytes.  Use inline code

      More-conservative ‘format’ quote restyling · fbb5531f
      Paul Eggert authored
      Instead of restyling curved quotes for every call to ‘format’,
      create a new function ‘format-message’ that does the restyling,
      and using the new function instead of ‘format’ only in contexts
      where this seems appropriate.

      Prefer ‘format’ to ‘substitute-command-keys’ when either will do
      to implement quoting style.  This generally makes the code simpler.

      Extend ‘format’ to translate curved quotes · 244c8016
      Paul Eggert authored
      This is a followup to the recent doc string change, and deals with
      diagnostics and the like.  This patch is more conservative than
      the doc string change, in that the behavior of ‘format’ changes
      only if its first arg contains curved quotes and the user prefers
      straight or grave quotes.  (Come to think of it, perhaps we should
      be similarly conservative with doc strings too, but that can wait.)
      The upside of this conservatism is that existing usage is almost
      surely unaffected.  The downside is that we'll eventually have to
      change Emacs's format strings to use curved quotes in places where
      the user might want curved quotes, but that's a simple and
      mechanical translation that I'm willing to do later.  (Bug#21222)
