g-ir-scanner fails with python-3.8

g-ir-scanner fails with python-3.8

[Ken Brown]

Trying to build harfbuzz, I get the following python failure with python-3.8

Traceback (most recent call last):
   File "/usr/bin/g-ir-scanner", line 65, in <module>
     from giscanner.scannermain import scanner_main

<module>
     from giscanner._giscanner import collect_attributes
ImportError: dynamic module does not define module export function 
(PyInit__giscanner)

The log of my last successful build of harfbuzz shows that python-3.6 was 
installed.  Do any of the python experts out there (Marco?  Jon?) know what the 
problem could be?

Thanks.

This a problem with the gobject-introspection package.

_giscanner.dll is linked with python2, but the shbang names 'python', 
which is now python3.

I have been working on rebuilding this package, but not quite there yet.

You can work around this by fixing the shebang in /usr/bin/g-ir-scanner 
to explicitly name python3.

Here are patches...

* 0002-gobject-introspection-1.54.1-4.patch:
    python3.8 is used explicitly.
      Shebangs of g-ir-doc-tool and g-ir-scanner are '/usr/bin/env python3.8'
      _giscanner.dll is linked with libpython3.8.dll

* 0001-Fix-a-patch-for-giscanner-shlibs.py-to-pass-a-pep8-c.patch:
    This has no effect while building.
    But needed in order to avoid an error in a test
      cygport gobject-introspection.cygport test

And with them, following build and test by cygport has succeeded
both in x86_64 and i686, on my local machine.

  cygport gobject-introspection.cygport download finish all test


But on scallywag, only x86_64 build is successful:

are you sure of those patches ?

*** ERROR: patch 
0001-Fix-a-patch-for-giscanner-shlibs.py-to-pass-a-pep8-c.patch will not 
apply

it does not work alone or together with the old patch

can you send the gobject-introspection.cygport ?

These patches are the last two commit from here for the time being:

https://cygwin.com/git-cygwin-packages/?p=git/cygwin-packages/playground.git;a=commitdiff;h=1f435122b29fdc5a7c3f71f6da0cb28bbb843847

which forked from the gobject-introspection 1.54.1-3
https://cygwin.com/git-cygwin-packages/?p=git/cygwin-packages/gobject-introspection.git;a=commit;h=cd7b82d762911316ae43708b30941fea4d7f718d

Atattched files are modified files based on 1.54.1-3.

gobject-introdpection.cygport: modified.
1.54.1-2-cygwin.patch: removed a trailing space.

Thanks, Lem.

I've rebuilt gobject-introspection for python39, using these patches. 
Sorry that took so long to get around to.

(It would be nice to update this to a later version, but that seems to 
require glib to be updated also...)

Oh, I overlooked them.


I looked into a log corresponding to the current version 1.54.1-3 [1].

[1]: https://cygwin.com/cgi-bin2/jobs.cgi?srcpkg=gobject-introspection&id=2763


* i686: No syntax error related to '__float128' [2]
  at gobject-introspection-1.54.1/gir/GL-1.0.gir.
  So, it is newly introduced

[2]: https://ci.appveyor.com/project/cygwin/scallywag/builds/39168275/job/11sd0x8ywqfe3v2c#L1456


* x86_64: There are similar errors ('unexpected typedef-name') already [3].

[3]: https://ci.appveyor.com/project/cygwin/scallywag/builds/39168275/job/4637hbqdc6b6htvj#L1476

This is 'expected', since (this version of?) g-ir-compiler doesn't know 
about __float128 as a built-in type.

There's no input which can legitimately make gcc terminate with segv, so 
trying to blame this on gobject-introspection is incorrect. There is a 
something going wrong in gcc, or (more probably) cygwin.

 From previous reports [1], [2] it seems to be a problem which only 
manifests itself on WOW64.

I think it just didn't get far enough, the same error is seen when 
building locally (which is how I had to build the package, because of 
the 'signal 11' problem)

Yeah, I don't know why the x86 build fails in the AppVeyor environment.

Downloading the builddir artifact, there isn't even a stackdump file, so 
the only way I can think of investigating futher is to RDP into the 
AppVeyor VM and try to trigger the crash with 'CYGWIN=error_start:gdb' set.

replace PyMODINIT_FUNC with PyObject* inside the PyInit code

I never really understood why , maybe is due to a wrong 
__declspec(dllexport) somewhere

Any tentative to change from python side instead of the packages side
has been ineffective.
