      Tune base64 decoding · 5abaea33
      Paul Eggert authored
      This improves performance of base64-decode-region by about 7.5% on
      my platform, and gets rid of some macros.
      * src/fns.c (IS_ASCII, IS_BASE64, IS_BASE64_IGNORABLE)
      (base64_value_to_char, base64_char_to_value):
      Now an array of two arrays.  All uses changed.
      (base64url_value_to_char, base64url_char_to_value):
      Remove.  All uses changed to the other array.
      (base64_char_to_value): Entries are now of type signed char, not
      short, since we can assume C99.  Use C99 initializers; this is
      clearer and caters to the (theoretical) possibility of systems
      that do not use ASCII or do not have 8-bit bytes.  Allow any index
      in the range 0..UCHAR_MAX instead of limiting it to 0..127, so
      that uses need not check for in-range indexes.  Also record
      padding chars.  All uses changed.
      (base64_decode_1): Always store number of chars in *NCHARS_RETURN,
      for simplicity.  All callers changed.  Speed up the byte-fetching.

      Use copy_file_range to copy files · 486a81f3
      Paul Eggert authored
      The copy_file_range syscall (introduced in Linux kernel
      version 4.5) can copy files more efficiently via server-side
      copy etc.

      * lib/copy-file-range.c, m4/copy-file-range.m4:
      New files, copied from Gnulib.
      * lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
      * src/fileio.c (Fcopy_file): Try copy_file_range first,
      falling back on read+write only if copy_file_range failed or
      if the input is empty and so could be a /proc file.

      Fix overflow issues in image rotation · 7c26e0b1
      Paul Eggert authored
      Also, do some refactoring to simplify code.
      * src/dispextern.h (INIT_MATRIX, COPY_MATRIX, MULT_MATRICES): Remove.
      * src/image.c (matrix3x3): New type, replacing all uses of 3x3 double.
      (matrix3x3_copy, matrix3x3_mult): New functions, replacing
      COPY_MATRIX, MULT_MATRICES.  Replace INIT_MATRIX by C initializers.
      (image_set_rotation): Use Fmod to avoid undefined behavior on
      double-to-int conversion and to reduce bignum rotations correctly.
      (image_set_crop): Finish up previous correction, by not re-setting
      width and height if compute_image_size has set them.
      Prefer shifting right by 1 to dividing by 2 if either will do.
