* glib/grand.c: Don't include <unistd.h> unless
HAVE_UNISTD_H. Include <process.h> on G_OS_WIN32.
(g_rand_new): Use getppid() only on G_OS_UNIX.
Fri Dec 19 11:49:21 2003 George Lebl <jirka@5z.com>
* glib/grand.c
glib/grand.h (g_rand_new) (g_rand_new_with_seed)
(g_rand_new_with_seed_array) (g_rand_set_seed_array): Add
the init_by_array functionality from the reference implementation
of the mersenne twister (mt19937ar.c) and change the naming
to fit with the rest of the grand API. New functions are
g_rand_new_with_seed_array, g_rand_set_seed_array. This is only
reliable/tested for the 2.2 version of the seeding as that's what
the reference implementation uses. Also modify g_rand_new to
get 4 longs from /dev/urandom since that will always be available
anyway and we get more entropy and if /dev/urandom is unavailable
use also 4 longs for seeding using secs, usecs, getpid and getppid.
For version 2.0 use only a simple seed again but be more careful
about seeding with secs/usecs in this case.
* glib/grand.c
glib/grand.h (g_rand_copy): Add g_rand_copy function to copy the
current state of the random number generator.
* glib/grand.c (g_rand_new): Add testing for EINTR when reading
from /dev/urandom
* tests/rand-test.c: add testing of the array seeding stuff against
the reference implementation, plus add statistical sanity check
to see that the values outputted are truly kind of random. And
check that g_rand_copy truly copies the state by checking a few
terms.

Fixes for #101264 and #99372:
* glib/gconvert.h, glib/gmain.c, glib/gmem.c, glib/gmessages.c,
glib/grand.c: Include gthreadinit.h and rename the thread
initialization functions a bit and let them start with _, so that
later we can stop exporting them.
* glib/gmem.c, glib/gmessages.c: Move the g_private_new() calls to
new functions. They have to be called after setting
g_threads_got_initialized to TRUE (see #101264).
* glib/gthread.c: Include gthreadinit.h. Renamed g_mutex_init() to
g_thread_init_glib(). Call the thread initialization functions
(which are not allowed to call g_private_new), then set
g_threads_got_initialized to TRUE, then call the other thread
initialization functions (which must not call anything but
g_private_new()).
* glib/gthreadinit.h: New private header to cleanly declare all
thread initialization functions.
* gthread/gthread-impl.c: Include gthreadinit.h. In
g_thread_init() just call g_thread_init_glib(), which in turn calls the
other functions (see #99372).
* glib/Makefile.am: Added gthreadinit.h.
2002-12-10 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* glib/grand.c (g_rand_int_range): Improve generation of
pseudo-random integers. (#99720, Morten Welinder <terra@diku.dk>)
* README.in, docs/reference/glib/running.sgml,
docs/reference/glib/tmpl/random_numbers.sgml,
docs/reference/glib/changes.sgml: Added notes about the new
algorithm.
2002-11-26 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* glib/grand.c, gthread/gthread-impl.c, tests/rand-test.c:
Improved the seeding algorithm. Old behaviour can be achived by
setting envvar G_RANDOM_VERSION to "2.0". (#99262)
* docs/reference/glib/glib-docs.sgml,
docs/reference/glib/Makefile.am: Renamed
docs/reference/glib/changes-2.0.sgml to
docs/reference/glib/changes.sgml and added section for changes
from 2.0 to 2.2 (Also corrected 1.0 to 1.2).
* README.in, docs/reference/glib/running.sgml,
docs/reference/glib/tmpl/random_numbers.sgml,
docs/reference/glib/changes.sgml: Added notes about the new
seeding algorithm.
2001-09-24 Bruno Haible <haible@clisp.cons.org>
* glib/gwin32.c (g_win32_getlocale): When the sublangid is
SUBLANG_DEFAULT, return the locale of the language's main country,
not a country-neutral locale. E.g. "en_US" instead of "en". Add
handling of LANG_SORBIAN. Fix typo for SUBLANG_CHINESE_SIMPLIFIED
(China == CN, CH == Switzerland). Ignore empty environment
variable values.
2001-09-28 Tor Lillqvist <tml@iki.fi>
* glib/makefile.{mingw,msc}.in: Add localcharset.o. Just copy the
source file from libcharset and compile in this directory.
* glib/giochannel.c: Mark rest of g_set_error strings for
translation, too.
* glib/giowin32.c: Add some debugging output functions, call them
when debugging.
(create_events, g_io_win32_msg_write): Free message fetched with
g_win32_error_message ().
(g_io_win32_check): Indentation fixes.
(g_io_win32_fd_read,g_io_win32_sock_read): Don't always return
G_IO_STATUS_NORMAL. Do return G_IO_STATUS_EOF if we got 0 bytes,
like on Unix. This helps making the test programs run
successfully.
* glib/gmain.c (g_poll): Return the code ifdeffed out with
TEST_WITHOUT_THIS. Can't remember why it was ifdeffed out. Things
seem to work as previously with the code in place. Especially
spawn-test didn't work with the code ifdeffed out (Bug#61067).
* glib/grand.c (g_rand_new): Don't try to use /dev/urandom unless
on Unix.
* glib/gspawn-win32-helper.c (WinMain): Remove Sleep(10000)
accidentally left in.
gthread:
2001-09-28 Tor Lillqvist <tml@iki.fi>
* gthread-win32.c: Use an extra level of indirection for GMutex.
It is now a pointer either to a pointer to a CRITICAL_SECTION
struct, or to a mutex HANDLE. This is needed in case the user
defines G_ERRORCHECK_MUTEXES. G_MUTEX_SIZE must correctly reflect
the size of *GMutex, but this used to vary depending on whether we
at run-time chose to use CRITICAL_SECTIONs or mutexes.
(g_mutex_free_win32_cs_impl, g_cond_free_win32_impl): Call
DeleteCriticalSection() when done with it.
* gthread-impl.c (g_thread_init_with_errorcheck_mutexes): Call
g_thread_impl_init() before accessing
g_thread_functions_for_glib_use_default, as the
g_thread_impl_init() function might modify it.
po:
2001-09-28 Tor Lillqvist <tml@iki.fi>
* POTFILES.in: Add iochannel.c and giowin32.c.
* sv.po: Remove a bogus fuzziness indicator.
2000-12-19 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* grand.c: Updated G_RAND_DOUBLE_TRANSFORM to be more
accurate. Redid g_rand_double() such that it returns 52 bits after
the point instead of 32 as before. That OTOH requires calling
g_rand_int() twice. Overhauled g_rand_int_range(), which is easier
now thanks to the new precision of g_rand_double(). Thanks to
Sverre Johansen <sj@ifi.uio.no> for the hint.
* grand.h: Added g_rand_boolean() and g_random_boolean()
macros. While they could be omitted due to extreme simplicity,
they make intention clearer in code and are therefore good to have.
* grand.c, grand.h: Renamed all 'min' and 'max' parameters to'
begin' and 'end' resp. to avoid making people think, that 'max' is
included in the interval. 'end' now isn't, whereas 'begin'
is. That's similar to the use in the STL.
* glib/glib-sections.txt: Added g_rand_boolean and
g_random_boolean macros.
* glib/tmpl/random_numbers.sgml: Updated.
2000-10-13 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* grand.c: Added inline documentation.
* docs/refernce/glib/glib-sections.txt: Added misc items.
* docs/refernce/glib/tmpl/random_numbers.sgml: Documentation for
the random number generator.
Wed Jul 26 12:59:31 2000 Tim Janik <timj@gtk.org>
* *.[hc]: applied patch from Andreas Persenius <ndap@swipnet.se> that
updates the license headers to the GNU Lesser General Public License,
as well as updating the copyright year to 2000.
1999-07-23 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* grand.c (g_rand_new): Use /dev/urandom, as it doesn't block,
which /dev/random might do. Do not XOR the time, when getting the
seed form /dev/urandom, as this is good itself. Prevent the
initial seed from being zero, which causes the PRNG to produce
only zeros. Hints from Colin Plumb <colin@pgp.com>.
1999-04-12 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* glib.h: Moved struct declaration up. Style fixes.
* grand.c: Style fixes. Only try to open /dev/random once.
* tests/rand-test.c (main): New tests; Slight bug fix.
1999-04-09 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* grand.c, tests/rand-test.c: New files to implement the Mersenne
Twister Pseudo Random Number Generator.
* glib.h, AUTHORS, Makefile.am, tests/Makefile.am: Changed
accordingly.
