Guile 1.7.91 has been released.

Guile 1.7.91 has been released.

[Marius Vollmer]

We are pleased to announce the release of Guile 1.7.91.  This is a
release candidate for Guile 1.8.  It can be found here:

    ftp://alpha.gnu.org/gnu/guile/guile-1.7.91.tar.gz

Its MD5 checksum is

    b2106c1b574e22ec67c4c2178074b5ec  guile-1.7.91.tar.gz

The plan is to release version 1.8.0 next weekend, 2006-01-19, if all
goes well.


The NEWS file is quite long.  Here are the most interesting entries:

  Changes since 1.6:

  * Guile is now licensed with the GNU Lesser General Public License.

  * The manual is now licensed with the GNU Free Documentation License.

  * We now use GNU MP for bignums.

  * We now have exact rationals, such as 1/3.

  * We now use native POSIX threads for real concurrent threads.

  * There is a new way to initalize Guile that allows one to use Guile
    from threads that have not been created by Guile.

  * Mutexes and condition variables are now always fair.  A recursive
    mutex must be requested explicitely.

  * The low-level thread API has been removed.

  * There is now support for copy-on-write substrings and
    mutation-sharing substrings.

  * A new family of functions for converting between C values and
    Scheme values has been added that is future-proof and thread-safe.

  * The INUM macros like SCM_MAKINUM have been deprecated.

  * The macros SCM_STRINGP, SCM_STRING_CHARS, SCM_STRING_LENGTH,
    SCM_SYMBOL_CHARS, and SCM_SYMBOL_LENGTH have been deprecated.

  * There is a new way to deal with non-local exits and re-entries in
    C code, which is nicer than scm_internal_dynamic_wind.

  * There are new malloc-like functions that work better than
    scm_must_malloc, etc.

  * There is a new way to access all kinds of vectors and arrays from
    C that is efficient and thread-safe.

  * The concept of dynamic roots has been factored into continuation
    barriers and dynamic states.

See NEWS and the manual for more details.

Re: Guile 1.7.91 has been released.

[Michael Tuexen]

Hi Marius,

the check for socklen_t fails incorrectly because socklen_t is
defined in /sys/socket.h on Mac OS X, and on BSD systems in general.

What about using

AC_MSG_CHECKING(for socklen_t)
AC_TRY_COMPILE([#ifdef HAVE_SYS_TYPES_H
                 #include <sys/types.h>
                 #endif
                 #include <sys/socket.h>],
                [socklen_t x = 1; return 0;],
                [AC_MSG_RESULT(yes)],
                [AC_MSG_RESULT(int)
                 AC_DEFINE(socklen_t, int, [Define a type for  
socklen_t.])])

instead of

AC_CHECK_TYPE(socklen_t, int)


Best regards
Michael

FYI, on `powerpc-unknown-linux-gnu', everything seems to work fine: all
standalone C tests pass, and all Scheme tests do as well.

  Totals for this test run:
  passes:                 11538
  failures:               0
  unexpected passes:      0

  unresolved test cases:  9
  untested test cases:    0
  unsupported test cases: 9
  errors:                 0

  PASS: check-guile

BTW, I'd strongly recommend using SHA1 sums (e.g., via `sha1sum', part
of GNU Coreutils) rather than MD5.  See the example at
http://www.cits.rub.de/MD5Collisions/ if in doubt.  ;-)

Thanks,

Re: Guile 1.7.91 has been released.

In solaris 10, I think the readdir_r usage is incorrect.

 gcc -DHAVE_CONFIG_H -I. -I. -I.. -I.. -I.. -g -O2 -Wall -Wmissing-prototypes -MT filesys.lo -MD -
MP -MF .deps/filesy

filesys.c:860: error: (Each undeclared identifier is reported only once
filesys.c:860: error: for each function it appears in.)
filesys.c:863: error: too many arguments to function `readdir_r'

readdir_r is now:

     struct dirent *readdir_r(DIR *dirp, struct dirent *entry);

I changed filesys.c line 860 (or thereabouts) from:

    union {
      struct dirent ent;
      char pad1 [sizeof(struct dirent) + NAME_MAX];
      char pad2 [offsetof (struct dirent, d_name) + NAME_MAX + 1];
    } u;
    SCM_SYSCALL (readdir_r ((DIR *) SCM_CELL_WORD_1 (port), &u.ent, &rdent));

to:

    struct dirent ent;
    SCM_SYSCALL (readdir_r ((DIR *) SCM_CELL_WORD_1 (port), &ent));

and the rest went smoothly, although I had to remove -Werror from libguile/Makefile
because:

Well, they get to choose both texts that have a MD5 collision.
Looking at the PostScript source reveals that the texts have been
rigged, which should be enough if this goes to court.  In our case, an
attacker would need to find a second meaningful text that collides
with the text that we provide.  I guess that is much harder to do.

And the tarball is signed with a SHA1 hash anyway.  Maybe I should
include the signature in the announcement and not a checksum...

This is recommended for portability by the glibc manual.

You've probably got NAME_MAX, is it hiding in some strange header?

Re: Guile 1.7.91 has been released.

[Bill Schottstaedt]

I don't think NAME_MAX is defined anywhere -- the documentation says
you should use pathconf instead.  Here's the portion of limits.h where
they commented out NAME_MAX:

/*
 * POSIX 1003.1a, section 2.9.5, table 2-5 contains [NAME_MAX] and the
 * related text states:
 *
 * A definition of one of the values from Table 2-5 shall be omitted from the
 * <limits.h> on specific implementations where the corresponding value is
 * equal to or greater than the stated minimum, but where the value can vary
 * depending on the file to which it is applied. The actual value supported for
 * a specific pathname shall be provided by the pathconf() (5.7.1) function.
 *
 * This is clear that any machine supporting multiple file system types
 * and/or a network can not include this define, regardless of protection
 * by the _POSIX_SOURCE and _POSIX_C_SOURCE flags.
 *
 * #define      NAME_MAX        14
 */


I'd be happy to test anything, of course.  (The d_name field is still defined
to be 1 char long, so I think the glibc comment still pertains to Solaris,
but I'm really no expert about this system!).

I guess that means you can't just define a struct.  What does the
readdir_r man page say you should do?  pathconf like you said?

Yes, here's the relevent portion of man readdir_r:


The caller must allocate storage pointed to by entry  to  be
     large  enough  for  a dirent structure with an array of char
     d_name  member  containing  at  least  NAME_MAX  (that   is,
     pathconf(directory,   _PC_NAME_MAX))   plus   one  elements.
     (_PC_NAME_MAX is defined in  <unistd.h>.)


I found some examples by Googling for readdir_r and _PC_NAME_MAX.

Incomplete bit of code below, it's not pretty but I guess it's what
has to be done.


#if HAVE_READDIR_R
    /* On Solaris 2.7, struct dirent only contains "char d_name[1]" and the
       application is expected to provide a buffer of "sizeof(struct dirent)
       + NAME_MAX" bytes.

       The glibc 2.3.2 manual notes this sort of thing too, and advises
       "offsetof(struct dirent,d_name) + NAME_MAX + 1".

       On Solaris 2.10, there's no NAME_MAX because it varies according to
       the filesystem, one is expected to use pathconf().

       So the code below tries a plain struct dirent, plus all three of the
       above possibly bigger sizes, to establish the buffer.  If we're not
       using pathconf then the size is a constant and we don't need to
       malloc/free, but let's assume for modern systems pathconf is usual so
       most of the time we'll be wanting a dynamic size.  */

    size_t  bufsize = sizeof (struct dirent);
    char    *buf;
    int     old_errno;
#ifdef NAME_MAX
    bufsize = SCM_MAX (bufsize, sizeof(struct dirent) + NAME_MAX);
    bufsize = SCM_MAX (bufsize, offsetof (struct dirent, d_name) + NAME_MAX + 1\);
#endif
#ifdef _PC_NAME_MAX
    {
      char *c_dirname = scm_to_locale_string (SCM_FILENAME (port));
      long name_max = pathconf (c_dirname, _PC_NAME_MAX);

      errno = old_errno;

Oops, I see opendir doesn't record the opened directoryname.  Hmm.  It
might be easiest for now to just stick a mutex around plain readdir()
and worry later about readdir_r and its buffer size.

trying to get this, I haven't figured it out yet.

Well, since *you* are malicious, you could very well have prepared a
second tarball whose MD5 is the same and which you will propagate
during the days following the announcement.  ;-)

Seriously, this kind of attack is really about the level of trust one
can have in the *emitter* of the tarball and checksum.

Right.

Thanks,

GNU (aka. GNU/Hurd) may very well have the same problem. (arbitrary

check this?

Hi Marius,

what is your plan for maintaining the branches?  I've just put Ludovic's
scm_t_sweep_statistics patch in HEAD, can I also put it 1.8?

BTW, maybe you should also announce it on `info-gnu@gnu.org' (which is
relayed as the `gnu.announce' newsgroup).

Ahh, that never occured to me... I don't tend to think of _me_ as the

The release-1-6 branch remains stable of course, and the release-1-8
branch will be stable after 1.8.0 has been released, and is now in
feature freeze.  "Stable" should mean "we try very hard to not
regress and to remain binary compatible".

No. :-) I will look at it more closely, tho.  Maybe it makes sense to
put it into 1.8.1.

Perhaps you're on to something -- the "inline" business reminded me of
the old pstate bug where a variable was being optimized off the stack
causing premature gc, or something like that.  So, I rebuilt guile using
-g3 and not -O2, and the build ran to completion!  Unfortunately, it's still
not right; guile doesn't segfault but I get:

What happens after the check fails?  Will Guile compile correctly
anyway?

(I tried 1.7.90 on a friends Powerbook.  It compiled, but the
testsuite didn't run.)

If that's gcc 4 then it might be the same thing afflicting i386 under
-O3, that ceval/deval end up using a lot of stack.  Try increasing the
stack limit, ie. the guile one, wherever the default for that hides in
the sources ...

Also, on PPC, I can hardly get Guile running when compiled with `-O0': I
get "stack overflow" errors early during the startup phase when I do so.
If that is what you tried, I'd suggest compiling with at least `-O1'.

Thanks,
Ludovic.

Re: Guile 1.7.91 has been released (x86-64 segfault)

[Bill Schottstaedt]

I may be chasing pure randomness, but I find that the only file that cannot
be compiled -O2 is read.c -- I can switch back and forth between the segfault
and the stack overflow just by changing the optimization switch on that
file (optimizing all the rest).

I wonder if this might be related to a change I made recently in the
area of letrec initializers.  Would you mind reproing this under GDB,
with a breakpoint on the 

      ASSERT_SYNTAX_2 (scm_ilength (binding) == 2,
                       s_bad_binding, binding, expr);

line in check_bindings() in eval.c, and let me know what callstack you
have at that point?

Re: Guile 1.7.91 has been released.

Here it is -- I noticed while poking around earlier that the thing it
doesn't like is <#winder...> -- it was apparently expecting to call
cadr on it or something like that -- been kinda busy at work, so I
haven't had time to look into it.  (I had to insert an abort after expanding
the ASSERT_SYNTAX_2 macro -- it wasn't clear how to get into gdb
in .libs/lt-guile from the makefile otherwise, and .libs/lt-guile by
itself hits a different error).  Let me know if I can help in any way.
