      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.

      Improve make-temp-file performance on local files · a6ad98ad
      Paul Eggert authored
      For the motivation behind this patch, please see Bug#28023 and:
      http://emacshorrors.com/posts/make-temp-name.html
      Although, given the recent changes to Tramp, the related security
      problem in make-temp-file is already fixed, make-temp-file still has
      several unnecessary system calls.  In the typical case on GNU/Linux,
      this patch replaces 8 syscalls (symlink, open, close, readlinkat, uname,
      getpid, unlink, umask) by 2 (open, close).
      * admin/merge-gnulib (GNULIB_MODULES): Add tempname, now
      that Emacs is using it directly.
      * configure.ac (AUTO_DEPEND): Remove AC_SYS_LONG_FILE_NAMES;
      no longer needed.
      * lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
      * lisp/files.el (files--make-magic-temp-file): Rename from
      make-temp-file.
      (make-temp-file): Use make-temp-file-internal for
      non-magic file names.
      * src/fileio.c: Include tempname.h.
      (make_temp_name_tbl, make_temp_name_count)
      (make_temp_name_count_initialized_p, make_temp_name): Remove.
      (Fmake_temp_file_internal): New function.
      (Fmake_temp_name): Use it.
      * src/filelock.c (get_boot_time): Use Fmake_temp_file_internal
      instead of make_temp_name.
