      * src/fileio.c: Fix bug#36431 · fec111c9
      Stefan Monnier authored
      (decide_coding_unwind): Re-introduce.  Move text back to the gap.
      Return the new `inserted` via the unwind_data.
      (Finsert_file_contents): Use it.
      Make sure `inserted` is always 0 when we jump straight to `notfound`.
      Don't insert the text in the buffer until we know it's properly decoded
      for the byteness of the buffer.
      
      * test/src/fileio-tests.el (fileio-tests--insert-file-interrupt):
      Allow insert-file-contents to return an empty buffer in case of
      non-local exit in set-auto-coding-function.

      Clean up use of XFIXNUM etc. · 4893a09c
      Paul Eggert authored
      A few bits of the code were relying on the fact that XFIXNUM,
      XFIXNAT, and XUFIXNUM do something even with arguments that
      are not fixnums/fixnats.  Separate these rare uses out into
      XFIXNUM_RAW and XUFIXNUM_RAW.

      Fix range-checking bug if AREF (status, i) is out of int range.
      * src/data.c (arith_driver): Use XFIXNUM_RAW as we want
      efficient garbage if the value is not a fixnum.
      * src/dosfns.c (Fint86, Fdos_memput):
      Check that args are nonnegative.
      * src/image.c (lookup_image): Check that args are in range.

      semantics of the old functions without _RAW.
      (FIXNUMP): Move definition up to avoid forward use.

      check (when debugging) that the argument has the proper form.

      Remove fixnum restriction on some display vars · dfed333b
      Paul Eggert authored
      This is a minor patch to remove some fixnum restrictions.
      Many more such patches are needed, but one thing at a time.
      * doc/emacs/custom.texi (Examining): Update fill-column example.
      * src/buffer.c (fill-column, left-margin, tab-width)
      (buffer-saved-size, left-margin-width, right-margin-width)
      (left-fringe-width, right-fringe-width, scroll-bar-width)
      (scroll-bar-height, buffer-display-count):
      Allow any integer; do not restrict to fixnums.
      * src/character.h (SANE_TAB_WIDTH): Do not assume tab_width
      is a nonnegative fixnum.
      (sanitize_tab_width): Take a Lisp_Object integer, not an
      EMACS_INT.  Only use changed.
      * src/data.c (store_symval_forwarding): Remove unnecessary
      SYMBOLP since the predicate (e.g., Qintegerp) is always a
      symbol (leave the test in as an eassert).  Avoid assignments
      inside if-conditions.
      * src/fileio.c (Fdo_auto_save): Do not assume
      buffer-saved-size is a fixnum.  Avoid undefined behavior
      on EMACS_INT overflow by multiplying a fixnum by at most 4,
      not by at most 13.
      * src/window.c (set_window_buffer): When buffer-display-count
      is too large for a fixnum, make it a bignum.
      * src/xdisp.c (FILL_COLUMN_INDICATOR_NEEDED): Remove macro, ...
      (fill_column_indicator_column): ... replacing with this new function.
      All uses changed.  The function is a bit pickier, to prevent
      problems with non-character fixnums and columns out of range
      for int, and to remove the assumption that integers are in
      fixnum range.
      (append_space_for_newline, extend_face_to_end_of_line):
      Avoid undefined behavior with signed integer overflow.
      Simplify.

      Formerly they were fixnums, which led to problems when dealing

      Fix recent change in fileio.c · 4a5a1750
      Eli Zaretskii authored
      * src/fileio.c (get_homedir) [WINDOWSNT]: Convert $HOME to UTF-8.
      (Fexpand_file_name): Don't convert it here.

      Act like POSIX sh if $HOME is relative · 90027650
      Paul Eggert authored
      POSIX says sh ~/foo should act like $HOME/foo even if $HOME is
      relative, so be consistent with that (Bug#33255).
      * admin/merge-gnulib (GNULIB_MODULES): Add dosname.
      * src/buffer.c (init_buffer): Use emacs_wd to get
      initial working directory with slash appended if needed.
      (default-directory): Say it must be absolute.
      * src/emacs.c (emacs_wd): New global variable.
      (init_cmdargs): Dir arg is now char const *.
      (main): Set emacs_wd.
      * src/emacs.c (main) [NS_IMPL_COCOA]:
      * src/fileio.c (Fexpand_file_name):
      Use get_homedir instead of egetenv ("HOME").
      * src/fileio.c: Include dosname.h, for IS_ABSOLUTE_FILE_NAME.
      (splice_dir_file, get_homedir): New functions.
      * src/xrdb.c (gethomedir): Remove.  All callers changed
      to use get_homedir and splice_dir_file.
      * test/src/fileio-tests.el (fileio-tests--relative-HOME): New test.

      file-attributes cleanup · 662bee7d
      Paul Eggert authored
      Mostly, this replaces magic-number calls like (nth 4 A) with
      more-informative calls like (file-attribute-access-time A).
      It also fixes some documentation and minor timestamp coding

      Improve bignum support for system types · d77d01d2
      Paul Eggert authored
      Use bignums when Emacs converts to and from system types like
      off_t for file sizes whose values can exceed fixnum range.
      Formerly, Emacs sometimes generted floats and sometimes ad-hoc
      conses of integers.  Emacs still accepts floats and conses for
      these system types, in case some stray Lisp code is generating
      them, though this usage is obsolescent.
