Re: [PyQt] double free issue with OUT-argument
Which version of SIP? I think this is fixed in SIP v4.10. It in fact is, and upgrading from a 4.9 release candidate or some such helped. Thanks. Unrelated... There is a memory leak in your %ConvertToTypeCode as PySequence_GetItem() returns a new reference to the item. However you should use the PyTuple functions anyway (which don't return a new reference) because you are using PyArg_ParseTuple() to do the conversion. Thank you for pointing that out... my wrap-fu isn't to great ;) diez ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
[PyQt] double free issue with OUT-argument
Hi,
wrapping happily away a 3D-engine, I encounter the following problem:
import irrlicht
core = irrlicht.irr.core
q = core.quaternion()
q.toEuler()
python(3701) malloc: *** error for object 0x474b70: double free
*** set a breakpoint in malloc_error_break to debug
(0.0, -0.0, 0.0)
This is the declaration of toEuler in .sip:
void toEuler(irr::core::vector3df euler /Out/) const;
As you can see, it's supposed to modify a passed vector in place.
However, I declared vectors to be converted from to tuples, by this
code mapping:
%MappedType irr::core::vector3df
{
%TypeHeaderCode
#include vector3d.h
%End
%ConvertFromTypeCode
if (!sipCpp)
return PyTuple_New(0);
irr::core::vector3df *v = (irr::core::vector3df *)sipCpp;
return PyTuple_Pack(3,
PyFloat_FromDouble(v-X),PyFloat_FromDouble(v-Y),PyFloat_FromDouble(v-Z));
%End
%ConvertToTypeCode
if (sipIsErr == NULL) {
if(PySequence_Check(sipPy) PySequence_Length(sipPy) == 3) {
for(int j = 0; j 3; j++) {
PyObject *v = PySequence_GetItem(sipPy, j);
if(!PyFloat_Check(v) !PyInt_Check(v)) {
return false;
}
}
return true;
}
return false;
}
if (sipPy == Py_None) {
*sipCppPtr = NULL;
return 0;
}
irr::core::vector3df *v = new irr::core::vector3df();
PyErr_Clear();
irr::core::vector3df t = *v;
if(PyArg_ParseTuple(sipPy, fff, t.X, t.Y, t.Z)) {
*sipCppPtr = v;
return 1;
} else {
delete v;
*sipIsErr = 1;
return 0;
}
%End
};
Looking at the generated code, it seems to me it is perfectly fine - it
creates a new vector instance, passes that in, converts it to a tuple,
and deletes it.
extern C {static PyObject *meth_irr_core_quaternion_toEuler(PyObject
*, PyObject *);}
static PyObject *meth_irr_core_quaternion_toEuler(PyObject *sipSelf,
PyObject *sipArgs)
{
int sipArgsParsed = 0;
{
irr::core::vector3df * a0;
irr::core::quaternion *sipCpp;
if
(sipParseArgs(sipArgsParsed,sipArgs,B,sipSelf,sipType_irr_core_quaternion,sipCpp))
{
PyObject *sipResult;
a0 = new irr::core::vector3df();
sipCpp-toEuler(*a0);
sipResult =
sipConvertFromNewType(a0,sipType_irr_core_vector3df,NULL);
delete a0;
return sipResult;
}
}
/* Raise an exception if the arguments couldn't be parsed. */
sipNoMethod(sipArgsParsed,sipName_quaternion,sipName_toEuler);
return NULL;
}
I don't understand the behavior - anything I miss?
Regards,
Diez

[PyQt] casting issues
Hi, when wrapping a C++-library with SIP ( 4.9-snapshot-20090821) I run into a couple of issues. First of all, the library I wrap has a hierarchy of classes (all descending from ISceneNode) which I wrapped. Now through an instance of a so-called ISceneManager, I can access instances of the current scene-graph which are ISceneNode-instances. Consequently, the signature for one of the accessory-methods looks like this: ISceneNode *getSceneNodeFromID(int) So far, so good. Now problem number one comes up: I *know* a certain node is of type e.g. IMeshSceneNode. But when I access it via the above method, all I get is an ISceneNode. My C++-foo is rusty, and I know that RTTI isn't always available - I just wonder: is there a way for SIP to figure out the actual type of the instance returned, and wrap it accordingly? If yes, what do I need to do to enable that feature? However, the library in question offers a getType()-call on ISceneNodes, and this I can use to write casting-code myself. So I tried sip.cast, and that's my second issue for today: this dramatically segfaults for me. What works though is sip.unwrapinstance and sip.wrapinstance called in succession. The subsequent tinkering with the nodes shows that it actually works. So the question is - why does sip.cast bomb? I use it like this: sip.cast(terrain, scene.IMeshSceneNode) Regards, Diez ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

[PyQt] banging my head on returning short* as void*
Hi, I'm trying to wrap a method with the following signature: virtual const u16* getIndices() const where u16 is typedef'd as simple unsigned short. Actually, what I'm really just need is a void* here - the indices are passed to some other function which takes them as such. So I tried various things - just giving the above signature makes sip fail (understandably) with sip: irr::scene::SMeshBuffer::getIndices() unsupported function return type - provide %MethodCode and a C++ signature error: command '/Library/Frameworks/Python.framework/Versions/2.6/bin/sip' failed with exit status 1 So I tried altering the return-type to void*, what made GCC fail with cc1plus: warning: command line option -Wstrict-prototypes is valid for C/ObjC but not for C++ sipirrlichtirrsceneSMeshBuffer.cpp:37: warning: deprecated covariant return type for ‘virtual void* sipirr_scene_SMeshBuffer::getVertices() const’ ../irrlicht-1.5_svn/include/CMeshBuffer.h:47: warning: overriding ‘const void* irr::scene::CMeshBufferT::getVertices() const [with T = irr::video::S3DVertex]’ sipirrlichtirrsceneSMeshBuffer.cpp:40: error: conflicting return type specified for ‘virtual void* sipirr_scene_SMeshBuffer::getIndices() const’ ../irrlicht-1.5_svn/include/CMeshBuffer.h:77: error: overriding ‘const irr::u16* irr::scene::CMeshBufferT::getIndices() const [with T = irr::video::S3DVertex]’ sipirrlichtirrsceneSMeshBuffer.cpp: In member function ‘virtual void* sipirr_scene_SMeshBuffer::getVertices() const’: sipirrlichtirrsceneSMeshBuffer.cpp:105: error: invalid conversion from ‘const void*’ to ‘void*’ sipirrlichtirrsceneSMeshBuffer.cpp: In member function ‘virtual void* sipirr_scene_SMeshBuffer::getIndices() const’: sipirrlichtirrsceneSMeshBuffer.cpp:150: error: invalid conversion from ‘const void*’ to ‘void*’ irr_scene.sip: In function ‘PyObject* meth_irr_scene_SMeshBuffer_append(PyObject*, PyObject*)’: irr_scene.sip:1062: warning: comparison between signed and unsigned integer expressions irr_scene.sip:1065: warning: comparison between signed and unsigned integer expressions error: command 'gcc-4.2' failed with exit status 1 I found sipConvertFromVoidPtr, but don't know how to really use that.

Re: [PyQt] sip 4.8.2 error: sip: Unsupported type argument to type2string()
Hi, as always, your support is plain awesome! See below for a follow-up-question: the subject pretty much says it all. I upgraded to the latest SIP because I experienced a strange endless-loop-kind of behavior in the 4.7.* I had before, and now my building bails out with the sip: Unsupported type argument to type2string() error message. You can find the mercurial repository at https://bitbucket.org/deets/irrsinn/ Any ideas? Two changes in tonight's snapshot... ...to fix the type2string() problem ...to detect recursive class hierarchies - it's now obvious what's causing your looping. Great, I've been bitten by that before - but this time there was quite a bit of time between altering the source, and trying to compile it again, so I forgot. You also have a couple of syntax errors - forgetting the // around annotations. Yep, saw these - it was the first time I was using them anyway, and thus I hadn't the syntax down. And the reason I started with them is that I have a memory-management-issue that is beyond my current understanding. The library I'm wrapping employs it's own refcounting-scheme. The calls grab and drop are used to in- and decrease the refcounter. Now this leaves me with the problem that - when I drop() an object, it get's garbage-collected by C++ - but Python keeps a reference, and will of course attempt to de-allocate the object again. - when I *don't* drop(), and the object is GC'ed by python, there should be an implicit drop() called. I don't see a special method __del__ which I could use to do that. So - any suggestions how to tie these two memory-management-systems together?

It needs to be what the documentation calls a generated type object which

I missed your call to sipFindClass().
Ah, ok, I was wondering if sip changed so much. Good to know it didn't,
but also good to know I can get a static reference don't need the
extra call.
It's almost certainly a bug in your handwritten code somewhere - not
necessarily in the code above.
I don't doubt that - I just don't find it... I created some test-code
that toys around with S3DVertex-objecs, and all works fine. I can
construct them, I can compare them using their overloaded ==-operator
,which invokes
sipParseArgs(sipArgsParsed,sipArg,1JA,sipClass_irr_video_S3DVertex,a0)
and that is working. I can access their members, some of them which are
mapped types.
Do you have any idea how to go about this - can I build SIP in
debug-mode, and then step into the conversion-code itself? How about
building the extension in debug-mode - it does have the -g-flag, but
also a -O3.

It's a wrapped structure, with the original name irr::video::S3DVertex.
After reading the aforementioned docs, I was under the impression that I need
to get a sipTypeDef to check convert. At least pointers of that kind are
taken from sipConvertToInstance and sipCanConvertToInstance.

[PyQt] wchar_t type mapping
Hi,
I want to wrap a method with the following signature:
virtual irr::gui::IGUIStaticText* addStaticText(const wchar_t* text,
const irr::core::rectirr::s32 rectangle,

TypeError: argument 1 of IGUIEnvironment.addStaticText() has an invalid type
So I tried to map the wchar_t from and to PyUnicode-objects. But this
gives me an error that says

[PyQt] problem with abstract classes
Hi,
I'm in the process of wrapping the irrlicht 3d engine. So far, things
have been working smoothly. However, now I stumbled over a problem that
so far has not been willing to be disappearing, intensive gdb-use
notwithstanding.
There is a pure abstract class in Irrlicht, IEventReceiver. It looks
like this:
//! Interface of an object which can receive events.
class IEventReceiver
{
public:
virtual ~IEventReceiver() {};
//! called if an event happened. returns true if event was processed
virtual bool OnEvent(SEvent event) = 0;
};
This class I wrapped in SIP this way:
class IEventReceiver /Abstract/ {
%TypeHeaderCode
#include IEventReceiver.h
%End
public:
bool OnEvent(irr::SEvent event);
};
Which seems to work fine. Now of course I'm having troubles subclassing
this class in Python, which is the reason I created a dummy-implemntation
namespace irr {
class PyIEventReceiver : public IEventReceiver {
public:
virtual ~PyIEventReceiver();
bool OnEvent(SEvent event);
};
};
It is declared in my SIP-file as this:
class PyIEventReceiver : irr::IEventReceiver {
public:
bool OnEvent(irr::SEvent event);
};
I can subclass this class in python, and my SEvent-marshalling-code
works fine as well, as the following test-script shows:
class MyER(irrlicht.irr.PyIEventReceiver):
def OnEvent(self, event):
print event
er = MyER()
event = (irrlicht.irr.EET_MOUSE_INPUT_EVENT, 100, 100, .5, 1)
er.OnEvent(event)
But now if I set this IEventReceiver to my IrrlichtDevice, I get the
following error (inside GDB):
Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_PROTECTION_FAILURE at address: 0x0008

UserReceiver here is a pointer to a IEventReceiver, which seems to be
correctly set. I tried stepping into the code, but wasn't able to.
This is with OSX 10.4, Python2.5, latest stable sip (4.7).
Any suggestions? Am I doing something fundamentally wrong wrt
implementation of C++-interfaces?

text() returns a QString, which you should look up in the qt-reference-manual.
That reveals the method
QString::utf8()

Then you need to _decode_ it as utf-8 to yield a unicode object. So the whole

Re: [PyKDE] QString in PyQt4 - Request for Comments
I disagree with Giovanni. I signal signatures could be made somewhat more pythonic without the adverse impact. For example, it could remove the C++ constant, pointer and reference indicators (const, * and ) that Python-only programmers don't really understand. As long as the change was consistent, you would not need to use a second manual. And it would make it easier to remember some signatures without referring to a manual or wondering whether the parameter was a constant, pointer or reference. If the change could be made whilst supporting the old fully qualified format, I'm all for it. Regarding the more general questions, I also think that things should be made a bit more pythonic without deviating much from the Qt API. Python unicode strings should be returned in place of QString, maybe with a way of using a switch to get the QString if desired. And I think that Python containers should be used in place of Qt's template containers. These two points I totally support - QString has bitten me more than once, and using the template classes appears somewhat archaic to me - especially because python is so strong and neatly integrated in the field of iterators and so on.

[PyKDE] latest eric3 snapshot rocks!
Hi, just got around testing the latest snapshot - great! The toolbar-search is close to what I always dreamt of. Only a few questions arose: - it's a combo-box - but for me, it doesn't do anything. - is it possible to bind the incremental search to some key? - same for search next/prev incremental. I looked in the shortcuts, but no luck. Maybe I missed it - it's pretty crowded in there by now. And some semantics of the emacs incremental search I really like, so maybe they are feasible, too: 1) If one presses C-s, the minibuffer opens, and one can start typing. The equivalent here would be that the first press would put the focus into the search field 2) if C-s is pressed again while in the minibuffer, the search next functionality is executed - thus, no shortcut is wasted. So if the focus is in the search field, pressing the same shortcut would search again. 3) Pressing C-w while searching will expand the search term to the word-boundary the cursor is currently over. I better explain this by example: Let's say you have a few methods called show_*, where * is of course something like tables or images or whatever. Now when I want to find one of these, e.g. show_tables, I type C-s, then type show_. I then repeat pressing C-s. Of course all strings containing show_ are found. Now when the cursor is positioned over something like self.show_^tables with ^ indicating the cursor position. I can press C-w, which will expand the search term to the next word boundary - in this case show_tables. So I only search for that subsequently. 4) Pressing C-s twice when not in the minibuffer (or, so to speak, once again with an empty buffer, as the first puts the focus there) will reuse the last search term. I don't know if and which of these things is easy to implement - I guess having at least the possibility of shortcuts for search next/prev shouldn't be too hard. All other stuff is just a suggestion. All in all, it's always impressing at which speed eric evolves and how useful for me it becomes - so far it's the only IDE that lured me away from XEmacs, and that includes TogetherJ and Eclipse as failing competitors...

Re: [PyKDE] [eric3] file/class browser
How should the editor know, which class a variable belongs to. Python is a dynamically typed language. This means, that the type of an object is determined at runtime. This is a very big difference to C++ or Java, where a scanner can parse the source and determine the type of an object even before the code is compiled. I'm pretty well aware of that - but I'm talking about visiting a file via the tabs, detecting code in it like self.foobar() and then one wants to visit foobar - which is located in the same file. So syncing the classbrowser with the currently visited file is nice. No reflection/type inference here. Somebody recommended to make a toolbar with an entry for the search expression and a find and find next button. The search should use the flags set last time the search dialog was used. How about that? The important part for me would be that it's fully Key-operated - in emacs, I press C-s for forward search, then start typing which does incrementally search. Pressing C-c twice makes the last search expression appear. C-r does the same backwards. Displaying the search term in a toolbar is ok, but the advantage of the minibuffer-style is that it occupies precious screenspace only when needed. And the ability to search forward/backward from the current cursor position with possible wrap arounds instead of always beginning at the top would also be great. Any chances for this? That is in. Just select the backwards checkbox and select Find Again (or press F3). It's not about searching backward, but about searching from the cursor position - instead of the beginnig, which is AFAIK the eric behaviour .I'm on my mac now and haven't eric running, so I can't check that out - but I was annoyed by that, and usually I know how to operate GUIs so I'd seen an option that changes that behaviour - I hope at least.

That could be added. What would it be good for? It's sometimes nice in larger projects when you browse a file that e.g. contains a class which has a method foo, which in turn calls a bar method in that very class. Then you can simply use the object browser to jump there instead of skimming through the file. BTW, a feature that I'm personally missing most in all not emacs/vi-flavoured editors is an incremental search with a minibuffer-style search dialog.The reason is simply that the rather large search dialog obstructs the editor view.

Re: [PyKDE] PyQt and sip: WId is undefined
I don't know PyQt myself (as I am helping with packaging), but we hope to have a consistent environment from Darwin, Mac OS X, Solaris, and NetBSD (which all have X). But maybe the PyQt-mac for Mac OS X will behave the same. What are your worries? I use PyQt on mac - and it doesn't require me to run X11, which I as a user think is very good. And there is no os-specific stuff in my apps to do (at least not regarding qt itself). The whole purpose of Qt is to behave the same - regardless of the platform. That's why it's called platform independed.. :) Diez ___ PyKDE mailing listPyKDE@mats.imk.fraunhofer.de http://mats.imk.fraunhofer.de/mailman/listinfo/pykde

Hello,
I'm working on my first PyQt application, and to get a feel for signals

is Not implemented yet, which tells me I'm doing something wrong.
Here is my ui.h code:

I've also tried the simple statement print %s, e, but I also get the

Can anyone help point me in the right direction?
The ui.h file is of no use here AFAIK. What you do is to subclass your
generated widget class and then override the slot method - that's all.

Re: [PyKDE] Re: [Eric] How to use ipython ?
Actually the IPython feature I'm the most missing, if not the only one, is completion. This is a valuable improvement over the standard python interpreter, when in the implementation/testing phase ; that's why it made sense to me to have IPython run inside a python IDE... My eric has tab-completion working in it's interpreter already - in form of a window popping up giving me the possible choices. Which is nice, but could IMHO enhanced a great deal by implementing in incrementally, like the autocompletion in scintill. Any chances we see that coming, Detlev?

Re: [PyKDE] pyuic doesn't import kde modules
As $subject says, pyuic does not seem to be aware of the fact that kde modules are needed when compiling .ui files that are using KDE widgets. To reproduce it: snip I came across this when designing a GUI (d'oh!), as soon as I added the first KDE widget, I had to manually add the missing includes before I was able to test. Did I miss something? In qt-designer you can add a form-comment that starts with Python: - all that follows will be copied literally into the generated source. So that's the place to put import kde statements. No idea how that works with kdevdesigner, didn't use it. But if its based on qt-designer, it will work.

Re: [PyKDE] Eric3 Usability Questions / Feedback
That could be done. Right now, directories don't have a context menu. Maybe, you can specify the entries, a context menu for directories should have in the various project browser. I'll look into that, hopefully this weekend. You are right. I just checked the Qt documentation and that is, what it should do. Unfortunately, I cannot see a reason, why the toolbars aren't shown in the context menu. Maybe you spot something. Hm. My own app doesn't make much use of toolbars so far, so I don't have expirience so far. But I'll see what happens to me if I try to extend my toolbars. The default file extension for the open dialog is determined by the extension of the current editor. That means, if the current editor is a Python file, *.py is selected, if it is an IDL file, *.idl is selected and so on. Good to know . What do you mean by outline view?

Is there any way to remove some of the toolbars? I can undock them, but can't seem to get rid of them. I second all these remarks on the usability - they are my concerns too. However I can see that point 1 is more complicated than it may seem, as creating a ui file most certainly needs some initial setup like base-class and name and so on, so that a dialog for that will resemble more or less the qt-designer new-ui file dialog/wizard. Which shouldn't be too complicated for simpler widgets, but the more elaborate wizards certainly take effort to reproduce whilst having limited benefit (its not too often that one creates an ui file compared to editing it) Regards, Diez ___ PyKDE mailing listPyKDE@mats.imk.fraunhofer.de http://mats.imk.fraunhofer.de/mailman/listinfo/pykde

None of the options I've tried seem to work. Is this possible??
As I learned from Phil two days ago, for your case there exists
self.sender()
that you can call to get the source of your signal.
Before I knew that, I suggested this solution:
class Magic(QObject):
def __init__(self, dialog, key):
QObject.__init__(self)
self.dialog = dialog
self.key = key
def focusLost(self):
self.dialog.keyLostFocus(self.key)
magic = Magic(self, key).focusLost
self.connect(key, SIGNAL(focusLost()), magic)
self.magics.append(magic)
That should allow you to pass arbitrary parameters to to magic, that you then
in return can invoke your slot with.
Unfortunately, you have to keep a reference to magic-objects as otherwise the
GC will hit, and the connection is lost. Found that just yesterday - one
never stops to learn.

I get a segfault with this stack: #0 0x41c84829 in _Xutf8DefaultDrawImageString () from /usr/X11R6/lib/X11/locale/lib/common/xomGeneric.so.2 #1 0x41c84f73 in _Xutf8DefaultDrawImageString () from /usr/X11R6/lib/X11/locale/lib/common/xomGeneric.so.2 #2 0x41c851ea in _Xutf8DefaultDrawImageString () from /usr/X11R6/lib/X11/locale/lib/common/xomGeneric.so.2 #3 0x41c8552f in _Xutf8DefaultDrawImageString () from /usr/X11R6/lib/X11/locale/lib/common/xomGeneric.so.2 #4 0x41c85868 in _Xutf8DefaultDrawImageString () from /usr/X11R6/lib/X11/locale/lib/common/xomGeneric.so.2 #5 0x41c85e09 in destroy_fontdata () from /usr/X11R6/lib/X11/locale/lib/common/xomGeneric.so.2 #6 0x4142f461 in XCreateOC () from /usr/X11R6/lib/libX11.so.6 #7 0x4142e7f5 in XCreateFontSet () from /usr/X11R6/lib/libX11.so.6 #8 0x40d71345 in QMapPrivateQFont::Script, QString::clear () from /usr/lib/libqt-mt.so.3 #9 0x40d71fe1 in QInputContext::QInputContext () from /usr/lib/libqt-mt.so.3 #10 0x40d9122c in QWidget::createInputContext () from /usr/lib/libqt-mt.so.3 #11 0x40d58798 in QApplication::x11ProcessEvent () from /usr/lib/libqt-mt.so.3 #12 0x40d6e7d4 in QEventLoop::processEvents () from /usr/lib/libqt-mt.so.3 #13 0x40dd7498 in QEventLoop::enterLoop () from /usr/lib/libqt-mt.so.3 #14 0x40dd7348 in QEventLoop::exec () from /usr/lib/libqt-mt.so.3 #15 0x40dc3d51 in QApplication::exec () from /usr/lib/libqt-mt.so.3 #16 0x40a04027 in meth_QApplication_exec_loop (sipSelf=0x41beed6c, sipArgs=0x401a5034) at sipqtpart0.cpp:426590 #17 0x0810ea96 in PyCFunction_Call (func=0x4021137c, arg=0x401a5034, kw=0x0) at Objects/methodobject.c:73 #18 0x080c38d0 in call_function (pp_stack=0xb784, oparg=0) at Python/ceval.c:3439 #19 0x080bffe6 in eval_frame (f=0x8166d1c) at Python/ceval.c:2116 #20 0x080c1de6 in PyEval_EvalCodeEx (co=0x401fd658, globals=0x401c1df4, locals=0x401c1df4, args=0x0, argcount=0, kws=0x0, kwcount=0, defs=0x0, defcount=0, closure=0x0) at Python/ceval.c:2663 #21 0x080ba6ac in PyEval_EvalCode (co=0x401fd658, globals=0x401c1df4, locals=0x401c1df4) at Python/ceval.c:537 #22 0x080e87a2 in run_node (n=0x401b9348, filename=0xbb84 examples3/tut3.py, globals=0x401c1df4, locals=0x401c1df4, flags=0xb958) at Python/pythonrun.c:1267 #23 0x080e8745 in run_err_node (n=0x401b9348, filename=0xbb84 examples3/tut3.py, globals=0x401c1df4, locals=0x401c1df4, flags=0xb958) at Python/pythonrun.c:1254 #24 0x080e8707 in PyRun_FileExFlags (fp=0x8155008, filename=0xbb84 examples3/tut3.py, start=257, globals=0x401c1df4, locals=0x401c1df4, closeit=1, flags=0xb958) at Python/pythonrun.c:1245 #25 0x080e7493 in PyRun_SimpleFileExFlags (fp=0x8155008, filename=0xbb84 examples3/tut3.py, closeit=1, flags=0xb958) at Python/pythonrun.c:862 #26 0x080e6cb7 in PyRun_AnyFileExFlags (fp=0x8155008, filename=0xbb84 examples3/tut3.py, closeit=1, flags=0xb958) at Python/pythonrun.c:659 #27 0x08055683 in Py_Main (argc=2, argv=0xba34) at Modules/main.c:415 #28 0x08054e36 in main (argc=2, argv=0xba34) at Modules/python.c:23 Googling gave me only one message from nov 2003 that stated a problem with ui-designer - nothing more so far.

[PyKDE] Segmentation faults in pyqt
Hi,
I've been struggling with this for a while now. I've got pyqt in various
versions running on two machines - as debian testing package, or self-built.
It works nice and smoothly.
But on the machine I care most about - the one sitting on my desk at home - it
segfaults - regardless of what I try: latest versions of sip, snapshots and
debian packages. Also no difference if I use python 2.2 instead of 2.3.
When stracing, the last thing I get from it is this:
lect(4, [3], NULL, NULL, NULL)= 1 (in [3])
read(3, \1%\336\0\0\0\0\0\0\0\377\277\326\251\r\10\30\356C\10 ..., 32) = 32
writev(3, [{1\0\v\0\1\0!\0, 8}, {-*-*-medium-r-*-*-16-*-ISO8859-1..., 33},
{\0\0\0, 3}], 3) = 44
read(3, 0xbfffefd0, 32) = -1 EAGAIN (Resource temporarily
unavailable)
select(4, [3], NULL, NULL, NULL)= 1 (in [3])
read(3, \1%\337\0\17\0\0\0\1\0\377\277\326\251\r\10\30\356C\10..., 32) = 32
readv(3, [{:-ttf-andale mono-medium-r-norma..., 60}, {, 0}], 2) = 60
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++
These are the various versions of sip/pyqt I tried:
sip-4.0rc3 sip-snapshot-20040329
sip-4.0rc4 sip-snapshot-20040501
PyQt-x11-gpl-3.12 PyQt-x11-gpl-snapshot-20040502
PyQt-x11-gpl-snapshot-20040413
I didn't try every possible cobination - usually one of the sip4 and after
that a snapshot. When 3.12 was released, I tried that. Building always went
fine.
The only app that doesn't segfault is tut2.py.
Any pointers to how to debug this are appreciated - if neccessary, I'll built
python, qt and sip/pyqt from scratch as debug versions, but I'd prefer to
have someone saying that that actually makes debugging possible before I
undetake that tedious task.
regardless from the trouble at home - where I got the chance to work with
pyqt, it surely rocks
Regards,
Diez

[PyKDE] problem compiling PyKDE-3.11alpha7 kio module

Re: [PyKDE] segfault with pyqt sip latest snapshots
I had this problem but with a different version of both. I found that removing and rebuilding and reinstalling both solved this problem. I don't know why the problem occured though. The second time i didn't use any build options at all, just python build.py How exactly did you remove the installed stuff - is there a make target?

[PyKDE] segfault with pyqt sip latest snapshots
Hi, I'm experiencing nasty segfaults with these components: PyQt-x11-gpl-snapshot-20040413 sip-snapshot-20040329-196 Python 2.3.3 (#2, Feb 24 2004, 09:29:20) [GCC 3.3.3 (Debian)] on linux2 Building installing worked fine. The only example that works is tut2.py - everything else flashes for a splitsecond, then the program terminates. any suggestions? btw: I tried sip 4.0 rc 3 before - same thing there. And as there was no way to uninstall it, I simply overinstalled it using the sip snapshot. Afterwards, I recompiled/reinstalled pyqt without any problems. Regards, Diez B.

Re: [PyKDE] DCOP Problems and Solutions
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, I'd be interested in hearing opinions on any of this. I'll make some decision on kab in the next few days depending on what feedback I get. Now obviously I'm for putting kab in pyKDE :) I'm not sure what kjs exactly does - but working in python and then allowing java-script for scripting - doesn't make much sense to me. For the problem I want kab for - python play out its strenghs when dealing with conversions between different sorts of (string-based) formats. And there's plethorea of PDA/CellPhones out there, that could benefit from an fairly easy way to be synchronized, because all of them have their own format... Of course I'm not sure what kdepim is up to - maybe they will change great parts of the related interface, so putting effort into kab would make not much sense - at least now. Does anybody know what they are going to change for kde 3.2?
