[issue13157] Build Python outside the source directory

[Roumen Petrov]

Roumen Petrov  added the comment:

I wonder why you are not stopped by:
configure: error: source directory already configured; run "make distclean" 
there first.
(for sure you remove some files but not all)

Applied patch is save but I cannot understand what actually is resolved.
Note that someone already report as bug(?) attempt to build outside when first 
project is compiled in source.

Good bye cross compilation!
Any attempt  to improve python build system to support cross-build,  multilib

[issue13193] test_packaging and test_distutils failures

[Roumen Petrov]

Roumen Petrov  added the comment:

Test test_install and test_command_install_data interference cache . Adding 
clear_cache as clean up routine  will resolve reported issue with Spamlib. The 
patch is trivial. Also one of the test set clear_cache as cleanup.

Most important is why packaging use global variables . To me good solution will 
not use globals , but this  require authors to rewrite packaging itself.

[issue1597850] Cross compiling patches for MINGW

[Roumen Petrov]

Roumen Petrov  added the comment:

-1 for the patch (after review of cross-3.0-0.7.diff) :
1) AC_CHECK_TOOLS(CC,gcc cc) and AC_CHECK_TOOLS(CXX,g++ c++) is bogus 
2) "$CC -dumpmachine" when is added AC_CANONICAL_HOST is bogus
3) if (strcmp(buffe,me) "123")) is buggy

Good point is setup.py is to exclude default searches for header/libraries in 
/usr/XXX directories . Note that this is requested in other issues not related 
to cross compilation.

About pgen build i'm not sure that is wort to cross-build as there is no reason 
to recreate files , right ? To me this is only dependency issue.

It seems to me I forgot to upload version after updates in Lib/sysconfig.py

I could not understand what Florent Xicluna (flox). I could not reproduce it. 
To me update abspath -> realpath is bogus and with reverted update of 
Lib/sysconfig.py test_sysconfig pass.

This patch is restored previous behaviour and now symlinked system python into 
cross build tree will behave as before i.e. as expected ;)

- As configure script add new "substitute variable" LDVERSION" why do not use 
LDVERSION in Makefile instead $(VERSION)$(ABIFLAGS). Note first to replace in 
configure script LDVERSION="$(VERSION)" to LDVERSION="$VERSION" !

- May be $(LN) -s is not portable. What about to add macro AC_PROG_LN_S in

return value. Then replace all calls of sys.platform and get_platform() 
to use host_platform.

In the patch for this issue _get_platform is modiffed to return mingw32 
if   so host_platform will be 'minwg32'. Including compiler and etc. 
don't work well in cross-compilation environment as the build script is 
run with python from build system.

[Roumen Petrov]

Roumen Petrov  added the comment:

a) NoneType object is not iterable. If the function don't return empty list 
later distutil will fail on the lines like  libraries.extend(self.dll_libraries)

b) method for detection of a msvc runtime is not correct. If the method return 
a library GCC will link to two c-runtimes. Also some function dearation are not 
visible if is not specified appropriate preprocessor directive.

So I could not found reason this method to exist .

[issue1204] readline configuration for shared libs w/o curses dependencies

[Roumen Petrov]

Roumen Petrov <[EMAIL PROTECTED]> added the comment:

In the configure{.in} exist another bug:
--
AC_CHECK_LIB(readline, readline)
if test "$ac_cv_have_readline_readline" = no
then
  AC_CHECK_LIB(termcap, readline)
fi
--
but "grep _readline_readline configure" show that variable in use is
$ac_cv_lib_readline_readline, so the check for function termcap in
readline can be removed safely - it is never reached.

I would like to propose another patch that don't use possible unresolved
symbol to detect presence of library. The new patch will define
HAVE_LIBREADLINE. If necessary will check for dependent library
and link it in correct order. The script print messages like next:
--
checking how to link readline libs... -lreadline -lncursesw
checking for rl_callback_handler_install in -lreadline... yes
checking for rl_pre_input_hook in -lreadline... yes
checking for rl_completion_matches in -lreadline... yes
--

The patch is for branch release25-maint.
It is without changes in configure script, i.e autoconf has to run to
recreate it after applying.
The patch can be applied to trunk as well.

[issue3718] environment variable MACHDEP and python build system

[Roumen Petrov]

New submission from Roumen Petrov <[EMAIL PROTECTED]>:

A) The reason to propose this patch following paragraph
from README:

2) To set sys.platform to something sensible, pass the
   following environment variable to the configure script:

 MACHDEP=unicosmk

The sentence above is not true in all cases. It don't state how to pass
as example
1) MACHDEP=abcd
   export MACHDEP
   ./configure 
2) MACHDEP=abcd ./configure 
3) ./configure MACHDEP=abcd 

The Makefile.pre.in contain dependency rule "Run the configure script": 
that create config.status if file "configure" is changed as run the script.
>From above three samples for environment varaible passing only 3) will
save MACHDEP
into variable CONFIG_ARGS from generated Makefile.
The case 2) alwais lost it if config.status is created from makefile rule.
The case 1) will work only if developer don't remeber to set it every day.


B) The test case (note that MACHDEP isn't valid name!):
$ MACHDEP=linuxTEST ./configure --disable-ipv6
checking MACHDEP... linuxTEST

checking for build directories... done
configure: creating ./config.status

creating Makefile

Now lets see if "configure" script is changed:
$ touch configure; make
/bin/sh ./configure '--disable-ipv6'
checking MACHDEP... linux2 <-- MACHDEP is lost

checking for build directories... done
configure: creating ./config.status
config.status: creating Makefile.pre
config.status: creating Modules/Setup.config
config.status: creating pyconfig.h
config.status: pyconfig.h is unchanged
creating Modules/Setup
creating Modules/Setup.local
creating Makefile
CONFIG_FILES=Makefile.pre CONFIG_HEADERS= /bin/sh config.status
config.status: creating Makefile.pre
make -f Makefile.pre Makefile
make[1]: Entering directory `/python-release25-maint'
make[1]: `Makefile' is up to date. <--- extra
make[1]: Leaving directory `/python-release25-maint'
/bin/sh ./Modules/makesetup -c ./Modules/config.c.in \

The Makefile was updated, you may need to re-run make.
gcc -pthread -c 


Note an extra attempt to create Makefile.


C) Next lets see after patch:
(the python configuration is the same as above):
$ touch configure; make
/bin/sh ./config.status --recheck
running CONFIG_SHELL=/bin/sh /bin/sh ./configure  --disable-ipv6
MACHDEP=linuxTEST  --no-create --no-recursion
checking MACHDEP... linuxTEST  <-- MACHDEP is same as at
configure time

checking for build directories... done
configure: creating ./config.status
creating Modules/Setup
creating Modules/Setup.local
creating Makefile
/bin/sh ./config.status Makefile.pre
config.status: creating Makefile.pre
/bin/sh ./Modules/makesetup -c ./Modules/config.c.in \
-s Modules \
Modules/Setup.config \
Modules/Setup.local \
Modules/Setup
The Makefile was updated, you may need to re-run make.
gcc -pthread -c - 
(ignore failure here since MACHDEP=linuxTEST is used only to show problem)


D) Rerefence (from autoconf textinfo sections):
4.8.5 Automatic Remaking
7.2 Setting Output Variables (see macro AC_ARG_VAR)
16 config.status Invocation

[issue3754] minimal cross-compilation support for configure

[Roumen Petrov]

New submission from Roumen Petrov <[EMAIL PROTECTED]>:

This is minimal patch that add basic cross-compilation possibilities for
python build (configure script).

The patch add macro AC_CANONICAL_HOST.
This macro require files config.guess, config.sub. The patch don't
include them. You may obtain them from GNU automake tarbal.

As result of macro new variable $host ("host triplet":=cpu-verdor-os) is
used to detect so called "host system".

Since this is basic patch, detection of build system in native builds
based on $ac_sys_system and/or $ac_sys_release isn't replaced. This
detection isn't appropriate for cross-compilation environment as contain
values for "build system" and has to be replaces in addition by future
patches.


Also the patch posted in http://bugs.python.org/issue3718 (about
environment variable MACHDEP) isn't required for native builds, but will
help in case of cross-compilation.

[issue3871] cross building python for mingw32 with distutils

[Roumen Petrov]

New submission from Roumen Petrov <[EMAIL PROTECTED]>:

This is a completely new patch against trunk that try to resolve mingw32
build. The first version to show problems with current python builds
system, to propose solutions/work-arounds and to be stating point for
discussion. Also I prefer some issues to be resolved later when we agree
on the basic issues.

The patch is tested in cross-compilation environment and native build
has to be tested too. Also the patch show how to use cross-compilation
environment and require patch posted in
issue 3754 ("minimal cross-compilation support for configure") to be
applied first.

The new patch share many commons with issue 841454 "Cross building
python for mingw32" posted by Andreas Ames, on 2003-11-13), but build
process use distutils instead scons.
Also some mingw related changes from issue 1597850 ("Cross compiling
patches for MINGW" - Han-Wen Nienhuys, from 2006-11-16) are shared too,
but we differ in concept how to use cross-compilation environment.
The correct way is to use $host variable (see issue 3754).

Also my patch use python installed on build system along with some hacks
to overcome distutils limitations.

The main issue "how to select correct compiler" in cross-compilation
environment isn't resolved at all. The patch is tested with installed
python version 2.4. 
Usually the cross-compiler is installed in same directories as native
compiler but tools are prefixed by -- (see meanign of "host
triplet"). In this environment we can't cross-compile even if we select
mingw as compiler in arguments for "setup.py":
The method get_versions() from cygwinccompiler.py call find_executable
for to find gcc, ld, dllwrap but on build system they point to native
compiler and that aren't prefixed. Also the expression "result =
re.search('(\d+\.\d+(\.\d+)*)',out_string)" return as example
'2.17.50.0.6' and later StrictVersion fail since value is not in format
N.N{.N{A{N}}}. If we replace '*' with '?" in regular expression we will
get correct  result, but this isn't right solution.
So the question is 'how to pass compiler to distutils' (as example for
python 2.4) remain open.

Work-around: install mingw cross-suite in own directory (MINGW_ROOT) and
prepend PATH environment variable with both paths:
- $MINGW_ROOT/bin
- $MINGW_ROOT//bin where  is something like
i586-pc-mingw32 (depend from you host selected when you build suite).
In this case find_executable will find mingw ld and since -v option
return something like "GNU ld version 2.17.50 20060824", regular
expresion value that make StrictVersion happy.

Note that in both environment configure script find compiler tools
prefixed as example by "i586-pc-mingw32-".
My mingw is build for host "i386-mingw32msvc"(this isn't correct, but is
acceptable for host. For next version I plan to use for build the
correct one, i.e i386-pc-mingw32). So in the final Makefile I see:
CC= i386-mingw32msvc-gcc
AR= i386-mingw32msvc-ar
RANLIB= i386-mingw32msvc-ranlib

Also setup.py set compiler attribute linker_so - for details see
comments in the patch.

Another point is to link installed python in top-build directory so that
on posix system distutils read variables from our makefile instead from
installed in build system. In this case python_build (an internal to
distutils flag) is set.

A, but not common, build issue is that some python 2.4 versions will
search for pyconfig-32.h instead pyconfig.h.
Symptoms:
===

running build
running build_ext
error: ./pyconfig-32.h: No such file or directory

===
I see this on cent-os (5.0?), but I can't see on slackware 11.0.
This patch don't address this.
Just go in top-build directory and create a link, i.e. "ln -s
./pyconfig.h pyconfig-32.h".


If you system support emulation after build you may run python.
The build python search for modules. After patch modules are with suffix
same as for native build - .pyd. You may thin them to the top-build
directory or to follow binary distribution - create directory DLLs,
enter into it and link pyd-files:
$ for f in ../build/lib.*/*.pyd; do ln -sf $f; done


Differences between mingw build python and binary distribution(native
build):
Mingw build follow posix rules and will create more modules than native
build. In the native build they are part from main executable(buildin).
This is the list:
array, audioop, binascii, _bisect, _bytesio, cmath, _codecs_cn,
_codecs_hk, _codecs_iso2022, _codecs_jp, _codecs_kr, _codecs_tw,
_collections, cPickle, cStringIO, _csv, datetime, _fileio, _functools,
future_builtins, _heapq, _hotshot, imageop, itertools, _json, _locale,
_lsprof, math, mmap, msvcrt, _multibytecodec, operator, parser, _random,
strop, _struct, _sub

[issue3708] os.urandom(1.1): infinite loop

[Roumen Petrov]

Roumen Petrov <[EMAIL PROTECTED]> added the comment:

It seems to me that test case will fail on windows and vms platforms.
The case contain os.urandom(1.1) but in posixmodule.c for urandon
functions (windows and vms) exits:
  PyArg_ParseTuple(args, "i:urandom", &howMany))

./python.exe -c 'import os; print "%s" %(os.urandom(1.9))' =>
-c:1: DeprecationWarning: integer argument expected, got float

[issue2445] Use The CygwinCCompiler Under Cygwin

[Roumen Petrov]

Roumen Petrov <[EMAIL PROTECTED]> added the comment:

May be check for compiler.compiler_type (from sysconfig.py ) has to be
replaced with a check for descendant classes of UnixCCompiler, i.e. to
include mingw32 too ?

Also CygwinCCompiler __init__ has to be reviewed too. As example :
-
# Hard-code GCC because that's what this is all about.
# XXX optimization, warnings etc. should be customizable.
self.set_executables(compiler='gcc -mcygwin -O -Wall',
.
-
May override in unexpected way settings from customize_compiler.

I thin that proposed modification in sysconfig.py with removing(or
replacing)  of self.set_executables from CygwinCCompiler __init__  will
help me for issue3871 (cross building python for mingw32 with distutils). 

As example I will remove a hack in the setup.py:
---
@@ -196,8 +196,26 @@
 if compiler is not None:
 (ccshared,cflags) =
sysconfig.get_config_vars('CCSHARED','CFLAGS')
 args['compiler_so'] = compiler + ' ' + ccshared + ' ' + cflags
+
+# FIXME: Is next correct ?
+# To link modules we need LDSHARED passed to setup.py otherwise
+# distutils will use linker from build system if cross-compiling.
+linker_so = os.environ.get('LDSHARED')
+if linker_so is not None:
+args['linker_so'] = linker_so
+
 self.compiler.set_executables(**args)
---
Thanks to Hirokazu who point me, in an another thread, that cygwin build
don't use CygwinCCompiler.

[issue3871] cross building python for mingw32 with distutils

[Roumen Petrov]

Roumen Petrov <[EMAIL PROTECTED]> added the comment:

For the protocol: issue2445 impact proposed patch.
Also I finish the tests and I will upload soon new patch - I the current
patch (  rpetrov, 2008-09-15 02:08) "Modules/selectmodule.c" isn't
ported and this prevent socked and related modules to work.
Also I understand the one of the reasons python 2.6x to be linked with
msvcr90 - many of bugs related to math functions are fixed in this
version of runtime.

I forgot  an another issue in CygwinCCompiler __init__:
if gcc isn't version "2.91.57" then method will set dll_libraries to

About experimental_distutils.patch - extra changes that has to go in a

[issue3547] Ctypes is confused by bitfields of varying integer types

[Roumen Petrov]

Roumen Petrov <[EMAIL PROTECTED]> added the comment:

Yes this extra define was the problem.
Instead hint /* Windows */ what about /* MSVC, GCC(with -mms-bitfields) */ ?

The option -mms-bitfields is available for GCC compiler on mingw and
cygwin targets.


About test_bitfields.py:
- comment in test_mixed_4: if GCC compiler has option -mms-bitfields it
will produce code compatible with MSVC. May be comment has to include
this information. 

- may be method test_mixed_1 need similar comment as test_mixed_4, but
even without comment is fine with me.

[issue3995] iso-xxx/cp1252 inconsistencies in Python 2.* not in 3.*

[Roumen Petrov]

Roumen Petrov <[EMAIL PROTECTED]> added the comment:

I don't know iso codeset that define characters in code range 0x80 0x9f.
This range is reserved for control symbols.

The code of euro is 0xa4 in iso-8859-15. Also changes include symbols
like 1/2, 3/4 and I forgot other differences.

[issue3995] iso-xxx/cp1252 inconsistencies in Python 2.* not in 3.*

[Roumen Petrov]

Roumen Petrov <[EMAIL PROTECTED]> added the comment:

Thanks Martin for correction: yes not reserved - assigned.

Jean-Michel, you test case is incorrect. You terminal is run in CP1252
where byte \x80 is shown as euro sing. But if you run terminal(if is
possible in reported operating system) in ISO-8859-{1|15} this byte is a
control character without visual representation.

To avoid "visual" ambiguity you should use hex representation of characters:
1) >>> unicode('\x80', 'cp1252')
u'\u20ac'
2) >>> unicode('\xa4','iso-8859-15')
u'\u20ac'

For the second case in you terminal you should enter:
>>> unicode('¤','iso-8859-15')
u'\u20ac'
'¤'(cp1252) = \xa4 = 164 = '€'(iso-8859-15)

I guess you understand what is incorrect in you report.

[issue4010] configure options don't trickle down to distutils

[Roumen Petrov]

Roumen Petrov <[EMAIL PROTECTED]> added the comment:

One of the problems that I see in that LDFLAGS is Makefile variable and
Makefile is part of distribution for posix build systems.
If you set specific LDFLAGS and you want to distribute own python build
user will get you specific settings.
One another environment variable is OPT (if compiler don't accept -R XXX
may be -Wl,-rpath,XXX ?) and we may use it. Also OPT environment
variable is also Makefile variable and user specific settings will go
into distribution too :( .

I quick look into distutils code show that sysconfig.py don't parse
LDFLAGS and append environment variable LDFLAGS as is to the ldshared
variable.
So the first question is why setup.py parse only -L flags instead to
pass variable value as is (aka sysconfig.py).
The second question is why LDFLAGS is a Makefile variable ? 


For now I would like to know if you set on Solaris suitable
LD_RUN_PATH(for the build) and LD_LIBRARY_PATH (when run) did you
succeed to build and run python ?
