GNU Mes 0.19 released

GNU Mes 0.19 released

[Jan Nieuwenhuizen]

[-- Attachment #1: Type: text/plain, Size: 6640 bytes --]

We are pleased to announce the release of GNU Mes 0.19, representing
100 commits over 10 weeks.

Mes has now brought the Reduced Binary Seed bootstrap to Guix (bootstrap
a GNU/Linux system without binary GNU toolchain or equivalent) and work
is ongoing to audit and verify this bootstrap path in NixOS.

This release introduces strings as byte-array, hash-tables and native
structs.  While that does increase the footprint somewhat, it fixes
our performance issue; tinycc is now compiled in ~8min (WAS: ~1h30).

Next targets:

 - translate mes.c into unsnarfed mes.M2
 - use Gash to remove bash, coreutils&co, grep, sed, tar from the Guix
   bootstrap binaries
 - replace the NixOS bootstrap
 - use dietlibc, uClibc, ... for bootstrapping GNU (bash, binutils,
   gcc, tar) and remove Mes C lib+gnu?
 - bootstrap gcc-3.x or 4.x directly, drop initial gcc-2.95.3 target?
 - have M1+hex2 create gcc/tcc-usable object files?  archives?
 - Debian?
 - ARM, the Hurd?

Packages are available from Guix's core-updates branch.

* About

  GNU Mes[0] brings a Reduced Binary Seed bootstrap[1] to Guix[2] and
  potentially to any other interested GNU/Linux distribution, and aims
  to help create a full source bootstrap as part of the
  bootstrappable builds[3] effort.

  It consists of a mutual self-hosting Scheme interpreter written in
  ~5,000 LOC of simple C and a Nyacc-based C compiler written in Scheme.
  This mes.c is being simplified[4] to be transpiled by M2-Planet[5].

  The Scheme interpreter (mes.c) has a Garbage Collector, a library of
  loadable Scheme modules-- notably Dominique Boucher's LALR[6], Pre-R6RS
  [portable syntax-case[7] with R7RS ellipsis, Matt Wette's Nyacc[8] --and test
  suite just barely enough to support a simple REPL and simple
  C-compiler: MesCC.

  Mes+MesCC can compile an only lightly patched TinyCC[9] that is
  self-hosting.  Using this tcc and the Mes C library we now have a
  Reduced Binary Seed bootstrap for the gnutools triplet: glibc-2.2.5,
  binutils-2.20.1, gcc-2.95.3.  This is enough to bootstrap Guix for
  i686-linux and x86_64-linux.

  Mes is inspired by The Maxwell Equations of Software: LISP-1.5[10] -- John
  McCarthy page 13, GNU Guix's source/binary packaging transparency and
  Jeremiah Orians's stage0[11] ~500 byte self-hosting hex assembler.

* Download

  git clone git://git.savannah.gnu.org/mes.git

  Here are the compressed sources and a GPG detached signature[*]:
    https://ftp.gnu.org/gnu/mes/mes-0.19.tar.gz
    https://ftp.gnu.org/gnu/mes/mes-0.19.tar.gz.sig

  Use a mirror for higher download bandwidth:
    https://ftpmirror.gnu.org/mes/mes-0.19.tar.gz
    https://ftpmirror.gnu.org/mes/mes-0.19.tar.gz.sig

  Here are the MD5 and SHA1 checksums:

  99e134df87adc5fc5fd2c04941929c23  mes-0.19.tar.gz
  c9781b3b6a814acc985c2ac68caa111a56583bca  mes-0.19.tar.gz

  [*] Use a .sig file to verify that the corresponding file (without the
  .sig suffix) is intact.  First, be sure to download both the .sig file
  and the corresponding tarball.  Then, run a command like this:

    gpg --verify mes-0.19.tar.gz.sig

  If that command fails because you don't have the required public key,
  then run this command to import it:

    gpg --keyserver keys.gnupg.net --recv-keys 1A858392E331EAFDB8C27FFBF3C1A0D9C1D65273

  and rerun the 'gpg --verify' command.

Mes runs from the source tree and can also be built, packaged and
installed in Guix from a git checkout by running

    guix package -f .guix.scm

* Changes in 0.19 since 0.18
 ** Core
 *** The build system has been simplified.
 *** Mes now prints a backtrace upon error.
 *** Performance has been improved 2-8 times, making Mes 2-10 times slower than Guile.
 *** Mes now supports a module type and uses a `boot-module'.
 *** Mes now supports a hash_table type.
 *** Mes now supports a struct type.
 *** Mes now supports building a %bootstrap-mes seed from Guix.
 ** Language
 *** Records are now implemented using struct (WAS: vector).
 *** 44 new functions
 ceil, char-downcase, char-set-adjoin, char-set-complement,
 char-upcase, current-time, delete-file, dup, dup2, file-exists?,
 floor, frame-printer, get-internal-run-time, getcwd, gettimeofday,
 hash, hash-ref, hash-set!, hash-table-printer, hashq,
 hashq-get-handle, hashq-ref, hashq-set, inexact->exact,

 struct-vtable, with-error-to-file.
 ** MesCC
 *** Assembly defines have been cleaned-up: duplicates deleted, missing added, wrong fixed.
 *** MesCC now supports compiling GNU Bash and GNU Tar.
 **** 6 New functions
 getegid, geteuid, getppid, setgid, setuid, sigdelset, sigprocmask.

 _POSIX_VERSION.
 ** Noteworthy bug fixes
 *** Mes now supports characters #\xNN.
 *** Mes now supports assq-ref and assoc-ref with alist == #f.
 *** Mes now supports \xNN in strings.  This allows using Nyacc-0.86.0.
 *** MesCC now supports the unary plus operator.

Wow! I did not expect such a huge difference.

Is this about configure+make?

Do you have a document showing the bootstrap path — ideally in graph
form, i.e. with plantuml activity diagram?
http://plantuml.com/activity-diagram-legacy

The Hurd would be nice!

Thank you for your great work!

Best wishes,
Arne

Hi Arne,

You can see the current bootstrap path here:

    https://bootstrappable.org/projects/mes.html

This is without the path from virtually nothing to mes + mescc tools,
i.e. mes and mescc tools currently are bootstrap binaries here.

>>  - use Gash to remove bash, coreutils&co, grep, sed, tar from the Guix

You can see in the graph that “bootstrap-binaries” is a collection of
statically linked binaries including tar, gzip, patch, coreutils, etc.
Most if not all of these could be removed with Gash.

This is really cool! Thank you!

I do not see gmake in there. Is that covered by one of them, or can it
be built with them?

`make-mesboot0' is the initial build of GNU make.  You can read the full
Guix bootstrap build recipe here:

Ah, nice!

Again: Thank you very much!
