Tony Lownds: [ Patch #101816 ] Fixes shared modules on Mac OS X
1. Mac OS X is recognized by the Next-ish host recognition code as
"Darwin/1.2"
2. When specifying just --with-dyld, modules can compile as shared
3. --with-dyld and --with-next-framework, modules can compile as
shared
4. --with-suffix=.exe, and Lib/plat-darwin1.2 is being made, the regen
script invokes python as python.exe
[I had to reformat this patch a bit to make it work. Please test!]
Dan Wolfe: [ Patch #101823 ] Fix Darwin POSIX Thread redefinition
The patch below fixes the redefinition problem in Darwin with
_POSIX_THREADS. I'm not sure if this is the correct long term fix but
for now it fixes the problem and the fix is specific to Darwin.
Dan Wolfe: [ Patch #101824 ] On Darwin, remove unrecognized option
`-OPT:Olimit=0'
After many, many, many compiles, I finally got itchy of this warning
cluttering up the output... so I scratched (Darwin configs only) and
it's gone! :-)

Apparently, on SunOS 4.1.4_JL (and other?) OSes, -d on an empty string
always returns true. This closes SF bug #115392.
-D_HPUX_SOURCE and also turns on long long support.
Suggestion by stnor@sweden.hp.com (Stefan Norberg).
Please test this if you have access to HP-UX!!!
I can't test this, so I'm just checking it in with blind faith in Andy.
I've tested that it doesn't broeak a non-Pth build on Linux.
Changes include:
- There's a --with-pth configure option.
- Instead of _GNU_PTH, we test for HAVE_PTH.
- Better signal handling.
- (The config.h.in file is regenerated in a slightly different order.)
This allows dbmmodule.c to use either without having to add additional
options to the Modules/Setup file or make source changes.
(At least some Linux systems use gdbm to emulate ndbm, but only install
the ndbm.h header as /usr/include/gdbm/ndbm.h.)
enable it), but db.h was not found, the WITH_LIBDB macros was still being
defined, resulting in compilation errors. Also added a short explain when
bsddb support wasn't enabled (because db.h wasn't found) when the user
explicitly used --with-libdb on the configure command line.
- Fix bug in thread_pthread.h::PyThread_get_thread_ident() where
sizeof(pthread) < sizeof(long).
- Add 'configure' for:
- SIZEOF_PTHREAD is pthread_t can be included via <pthread.h>
- setting Monterey system name
- appropriate CC,LINKCC,LDSHARED,OPT, and CCSHARED for Monterey
- Add section in README for Monterey build
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.
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.
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.
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.
