This adds a configure check and if all goes well turns on the
PTHREAD_SCOPE_SYSTEM thread attribute for new threads.
This should remove the need to add tiny sleeps at the start of threads
to allow other threads to be scheduled.
support on Linux (and Solaris, I expect) for real.
The necessary symbols are defined once and for all,
under the assumption that they won't harm elsewhere.
out of the box on OSX 10.1. Untested by me (except for not having adverse
effects on 10.0.4) but it looks good, for now. Eventually we should not
trigger on the darwin version but test for something, but until I have
the time to install 10.1 myself I have no clue what to test on.
It would be nice if this got in to the 2.2a3 distribution.
I don't know what difference it makes, but '/' indeed makes less sense
as an include dir than '.', so I'm changing the default. Just so I
can close the bug. ;-)
I believe this works on Linux (tested both on a system with large file
support and one without it), and it may work on Solaris 2.7.
The changes are twofold:
(1) The configure script now boldly tries to set the two symbols that
are recommended (for Solaris and Linux), and then tries a test
script that does some simple seeking without writing.
(2) The _portable_{fseek,ftell} functions are a little more systematic
in how they try the different large file support options: first
try fseeko/ftello, but only if off_t is large; then try
fseek64/ftell64; then try hacking with fgetpos/fsetpos.
I'm keeping my fingers crossed. The meaning of the
HAVE_LARGEFILE_SUPPORT macro is not at all clear.
I'll see if I can get it to work on Windows as well.
- Do not compile unicodeobject, unicodectype, and unicodedata if Unicode is disabled
- check for Py_USING_UNICODE in all places that use Unicode functions
- disables unicode literals, and the builtin functions
- add the types.StringTypes list
- remove Unicode literals from most tests.
- Give a warning if you're on a case-insensitive filesystem and have
not specified --with-suffix.
- Don't require --with-dyld, it is now default for OSX/Darwin (suggested
by Martin v. Loewis)
- Don't define _POSIX_THREADS on Darwin, it's done by standard headers already
(fix by Tony Lownds)
- Don't use the Mac subtree anymore, the routines relevant to OSX/Darwin
have moved to a new file Python/mactoolboxglue.c.
the --with-suffix=.exe, but it seems that that is also true for cygwin
(or not? should I automatically set it?)
- Got --with-next-framework to build on OSX. This is only the build bit,
the install still has to be done manually. Moreover, the Python build order
isn't really suited to frameworks (where you want to do 'build lib',
'install lib and framework', 'link executable against installed framework'
in that order).
Also note that it isn't just Linux nice() that is broken: at least FreeBSD
and BSDI also have this problem. os.nice() should probably just be emulated
using getpriority()/setpriority(), if they are available, but I'll get to
that later.
This patch allows the readline module to build cleanly with GNU
readline 4.2 without breaking the build for earlier GNU readline
versions. The configure script checks for the presence of
rl_completion_matches in libreadline.
Add configure option --enable-unicode.
Add config.h macros Py_USING_UNICODE, PY_UNICODE_TYPE, Py_UNICODE_SIZE,
SIZEOF_WCHAR_T.
Define Py_UCS2.
Encode and decode large UTF-8 characters into single Py_UNICODE values
for wide Unicode types; likewise for UTF-16.
Remove test whether sizeof Py_UNICODE is two.
Mac/macglue.c into the core interpreter. This file contains the glue code that
allows extension modules for Mac toolboxes to live in different shared libraries
but still communicate with each other. The glue code is controlled by the
USE_MAC_TOOLBOX_GLUE define. [checked in for Jack]
into Makefile.pre.in; the configure script will only determine the basename
of the file.
This fixes installation of a Python built using C++, reported by Greg
Wilson.
builds during which he forgot to uncomment crucial library lines in
Setup, walks into Guido's East End nightclub with a tactical nuclear
weapon on his shoulder. Said nuclear weapon is promptly deployed
exactly where it will do the most good, right in the middle of
configure.in.
With this patch, the set of libraries autoconfigured in is extended to
include ndbm, gdbm, and crypt. This essentially eliminates any need to
tweak Setup for a normal Linux build.

of dbmmodule dynamically by default (otherwise it can pull in
dependencies with libdb that croak pybsddb3). This change moves the
Setup line for dbmmodule to Setup.config.in.
- when compiling with GCC on Solaris, use "$(CC) -shared" instead
of "$(CC) -G" to generate .so files
- when compiling with GCC on any platform, add "-fPIC" to OPT
(without this, "$(CC) -shared" dies horribly)
regardless of whether the system getopt() does what we want. This avoids the
hassle with prototypes and externs, and the check to see if the system
getopt() does what we want. Prefix optind, optarg and opterr with _PyOS_ to
avoid name clashes. Add new include file to define the right symbols. Fix
Demo/pyserv/pyserv.c to include getopt.h itself, instead of relying on
Python to provide it.
-Wstrict-prototypes options. This will make it a lot easier to keep
warnings under control in the first place in the future.
There is one known warning at this time, caught by the -Wstrict-prototypes
option. In Modules/main.c, the declaration of getopt() without parameters
gets a complaint (rightly) that it is not a proper prototype. The lack of
a complete prototype information should be corrected when the right
portability conditions have been identified.
Approved by the Guido.
Tony Lownds: [ Patch #101816 ] Fixes shared modules on Mac OS X
1. Mac OS X is recognized by the Next-ish host recognition code as
"Darwin/1.2"
2. When specifying just --with-dyld, modules can compile as shared
3. --with-dyld and --with-next-framework, modules can compile as
shared
4. --with-suffix=.exe, and Lib/plat-darwin1.2 is being made, the regen
script invokes python as python.exe
[I had to reformat this patch a bit to make it work. Please test!]
Dan Wolfe: [ Patch #101823 ] Fix Darwin POSIX Thread redefinition
The patch below fixes the redefinition problem in Darwin with
_POSIX_THREADS. I'm not sure if this is the correct long term fix but
for now it fixes the problem and the fix is specific to Darwin.
Dan Wolfe: [ Patch #101824 ] On Darwin, remove unrecognized option
`-OPT:Olimit=0'
After many, many, many compiles, I finally got itchy of this warning
cluttering up the output... so I scratched (Darwin configs only) and
it's gone! :-)
test -d "$directory"
to
test ! -z "directory" -a -d "directory"
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!!!
