which I can cast void* to and back again without losing information".
In pyport.h, we typedef Py_uintptr_t to mean this thing, which if the
platform supports, will be uintptr_t (otherwise, other accomodations
are made).
- Don't call both AC_CHECK_FUNCS and AC_REPLACE_FUNC for 'hypot', as the
latter already does everything the former does (because it's implemented as
a call to the former.)
- Don't call AC_CHECK_FUNC() without any 'action' clauses or with an action
clause that just defines HAVE_<function>. Instead, call AC_CHECK_FUNCS,
which defines 'HAVE_<function>' of itself, possibly with aditional 'action'
clauses.
No checks are removed by this patch, only moved around, and some duplicates
are removed.
Patch by Thomas Wouters <thomas@xs4all.net> with small changes of mine
(in main(), use return instead of exit).
Closes patch #100832
(but I can't assign it to myself, nor close it -- sorry)
disables it. The gc test is moved to just after the thread test, as
is the wctype-functions test.
Modules/Setup.config is generated instead of Modules/Setup.thread.
Applied SF patch #100684 (loewis) to fix help alignment bug.
64-bit readiness (the config values are needed for patches that I will
be submitting later today. The changes are as follows:
- add SIZEOF_OFF_T #define's to PC/config.h (it was already in configure.in)
- add SIZEOF_TIME_T #define to PC/config.h and configure
Needed for some buffer overflow checking because sizeof(time_t) is
different on Win64.
- add SIZEOF_FPOS_T #define
Needed for the Win64 large file support implementation.
- add SIZEOF_HKEY in PC/config.h only
Needed for proper Win32 vs. Win64 handling in PC/winreg.c
- #define HAVE_LARGEFILE_SUPPORT for Win64
- typedef long intptr_t; for all Windows except Win64 (which defines it
itself)
This is a new ANSI (I think) type that is useful (and used by me) for
proper handling in msvcrtmodule.c and posixmodule.c
- indent the nested #ifdef's and #defines in PC/config.h
This is *so* much more readable. There cannot be a compiler
compatibilty issue here can there? Perl uses indented #defines and it
compiles with everything.
threads use --without-threads. No extra tests of thread/compiler
combinations have been added.
--with(out)-thread and --with(out)-threads are completely
interchangeable.
--with-threads still supports the =DIRECTORY option for specifying
where to find thread libraries.
This patch adds the openpty() and forkpty() library calls to posixmodule.c,
when they are available on the target
system. (glibc-2.1-based Linux systems, FreeBSD and BSDI at least, probably
the other BSD-based systems as well.)
Lib/pty.py is also rewritten to use openpty when available, but falls
back to the old SGI method or the "manual" BSD open-a-pty
code. Openpty() is necessary to use the Unix98 ptys under Linux 2.2,
or when using non-standard tty names under (at least) BSDI, which is
why I needed it, myself ;-) forkpty() is included for symmetry.
create shared extensions rather than 'ld -G'. This ensures that shared
extensions link against libgcc.a, in case there are any functions in the
GCC runtime not already in the Python core.
Solaris 2 has stub implementations of the POSIX thread functions such as
pthread_detach in libc. This means that configure tries to use them without
-lpthread, then the test of pthread_create fails and the configuration
falls back to the Solaris thread library. This patch moves the test for
pthread_create in -lpthread ahead of the test for pthread_detach in libc.
The patch also ensures that -lpthread is at the start of the library list
when linking, to pick up POSIX thread semantics for fork (see below).
Justification.
Use of POSIX threads on Solaris ensures that the fork() call only runs the
thread that called fork() in the child. This is desirable to prevent (for
example) parent server or database threads running in the child. Sun's
-lthread library uses a traditional fork() which replicates all the
parent's threads in the child. I find this undesirable.
Digression.
The configure.in seems to always test for -lthread even if a POSIX library
is found. I'm not enough of a configure.in wizard to decide whether this is
desirable or how to fix it. It is also irrelevant to this patch - I just
spotted it while testing.
End of Digression.
least on Solaris (sometimes it's Unix98, sometimes it conforms to an
early draft).
Properly generate config.h.in using autoheader instead of editing it
manually; thanks, Guido!
Duzan, for AIX, to support C++ objects with static initializers, when
using the genuine IBM C++ compiler (namely xlC/xlC_r).
See accompanying patches to acconfig.h and importdl.c.
The following patches (relative to 1.5.2b1) enable Python dynamic
loading to work on NetBSD platforms that use ELF (presnetly mips and
alpha systems). They automaticly determine wether the system is ELF or
a.out rather than using astatic list of platforms so that when other
NetBSD platforms move to ELF, python will continue to work without
change.
Added AC_CHECK_SIZEOF(void *).
Added yet another test for pthreads (pthread_create may be in libc).
Added pthread_init to list of functions whose existence is checked.
(1) reorder the tests for -Olimit 1500 and -OPT:Olimit=0 so that the
latter test is performed first, and if it works, the former test is
skipped. This should get rid of the problem that the new SGI
compilers accept both but emit a warning about -Olimit 1500.
(2) The DGUX hack was somehow split in two by the Olimit tests,
probably as the result of a non-context diff. Moved this back
together again, after the Olimit tests.
it seems harmless for other platforms. It plays tricks with the name
of the library used to link with. Apparently DG/UX really wants a
shared library to link with if it wants shared modules to use symbols
from the library. I'm not sure why this wasn't an issue with 1.4;
DG/UX seems to be the only platform where moving to a single library
made things harder!
BTW This adds a target to create libpython$(VERSION).so; however this
target is *only* for DG/UX.
- add test for strptime (not used by the core but needed by Marc Lemburg's
Date object).
- Test for GNU ld on Solaris; need to add an extra linker option to
export symbols in that case.
enabled. This is done through a substitution in Modules/Setup.thread(.in).
Bill Janssen will be happy. The original idea was by Lele Gaifax (though
I changed the implementation to use a separate file).
from the main program to shared libraries. On mklinux, the old
'-rdynamic' doesn't work; the new '-Xlinker -export-dynamic' works
both there and on Intel Linux platforms.
Makefile.in: run config.status in "make recheck".
configure.in: add test for hypot().
config.h.in, configure: since configure.in changed.
rest: the usual boring stuff.
more trouble than it's worth at CWI and most other people seem to
install Python in the default (/usr/local) anway. Changed comment
describing --prefix in Makefile.in
