* NEWS: Corrected remarks about SCM_API.

        * configure.in: Defining USE_DLL_IMPORT definition to indicate
        usage of DLL import macros in `libguile/__scm.h'.
        (LIBOBJS): Removed `fileblocks.o' from the list of object files.
        Somehow Jim Blandy's patch from 1997 did not survive.

2001-11-04  Stefan Jahn  <stefan@lkcc.org>

        * configure.in (EXTRA_DEFS): Follow-up patch.  Using SCM_IMPORT
        instead of __SCM_IMPORT__.

        * readline.c (scm_readline_init_ports): Disable input/output
        stream redirection for Win32.  The readline package for Win32
        does not support this.  The guile-readline library works fine
        for command line editing.

        * readline.h (SCM_RL_API): Renamed __FOO__ macros into FOO.

2001-11-04  Stefan Jahn  <stefan@lkcc.org>

        * Makefile.am (libguile_la_LIBADD): Added $(THREAD_LIBS_LOCAL)
        here (was at guile_LDADD) which describes the dependency
        correctly and allows a clean build on Win32.

        * __scm.h (SCM_API): Follow-up patch.  Renamed __FOO__ macros
        into FOO.

        * __scm.h: USE_DLL_IMPORT indicates the usage of the DLL
        import macros for external libraries (libcrypt, libqthreads,
        libreadline and libregex).

        * coop-defs.h: Include <winsock2.h> for `struct timeval'.

        * posix.c (flock): Added support for flock() in M$-Windows.

        * guile.c (SCM_IMPORT): Follow-up patch.  Use SCM_IMPORT instead
        of __SCM_IMPORT__.

        * fports.c (getflags): Differentiate reading and writing pipes
        descriptors.

        * filesys.c (S_IS*): Redefine all of the S_IS*() macros for
        M$-Windows.

        * coop.c (coop_condition_variable_timed_wait_mutex): Use
        conditionalized error code if `ETIMEDOUT' is not available.
        (scm_thread_usleep): Remove bogus declaration of `struct timeval
        timeout'.

        * numbers.c (PTRDIFF_MIN): Moved this definition where it actually
        belongs.  That is because NO_PREPRO_MAGIC gets undefined after
        each inclusion of `num2integral.i.c'.
        (SIZE_MAX): Define NO_PREPRO_MAGIC if SIZE_MAX is undefined.

2001-11-04  Stefan Jahn  <stefan@lkcc.org>

        * md/Makefile.am (EXTRA_DIST): Added `i386.asm'.

        * md/i386.asm: New file.  Contains the Intel syntax version for
        nasm/tasm/masm of the file `i386.s'.

        * qt.h.in: Definition of QT_API, QT_IMPORT and QT_EXPORT.
        Prefixed each symbols which is meant to go into a DLL.

        * Makefile.am (libqthreads_la_LDFLAGS):  Put `-no-undefined'
        into LDFLAGS to support linkers which do not allow unresolved
        symbols inside shared libraries.
        (EXTRA_DIST): Add `libqthreads.def', which is an export file
        definition for M$-Windows.  It defines exported symbols.  This is
        necessary because the M$VC linker does not know how to export
        assembler symbols into a DLL.

2001-11-04  Stefan Jahn  <stefan@lkcc.org>

        * srfi-13.h, srfi-14.h, srfi-4.h: Follow-up patch.  Renamed
        __FOO__ macros into FOO.

2001-11-04  Stefan Jahn  <stefan@lkcc.org>

        * tests/ports.test: Run (close-port) before (delete-file) if
        necessary/advisory.

This directory contains some tests for Guile, and some generic test
support code.

To run these tests, you will need a version of Guile more recent than
15 Feb 1999 --- the tests use the (ice-9 and-let*) and (ice-9
getopt-long) modules, which were added to Guile around then.

For information about how to run the test suite, read the usage
instructions in the comments at the top of the guile-test script.

You can reference the file `lib.scm' from your own code as the module
(test-suite lib); it also has comments at the top and before each
function explaining what's going on.

Please write more Guile tests, and send them to bug-guile@gnu.org.
We'll merge them into the distribution.  All test suites must be
licensed for our use under the GPL, but I don't think I'm going to
collect assignment papers for them.



Some test suite philosophy:

GDB has an extensive test suite --- around 6300 tests.  Every time the
test suite catches a bug, it's great.

GDB is so complicated that folks are often unable to get a solid
understanding of the code before making a change --- we just don't
have time.  You'll see people say things like, "Here's a fix for X; it
doesn't cause any regressions."  The subtext is, I made a change that
looks reasonable, and the test suite didn't complain, so it must be
okay.

I think this is terrible, because it suggests that the writer is using
the test suite as a substitute for having a rock-solid explanation of
why their changes are correct.  The problem is that any test suite is
woefully incomplete.  Diligent reasoning about code can catch corner
conditions or limitations that no test suite will ever find.



Jim's rule for test suites:

Every test suite failure should be a complete, mysterious surprise,
never a possibility you were prepared for.  Any other attitude
indicates that you're using the test suite as a crutch, which you need
only because your understanding is weak.
