[pygccxml-development] What am I doing wrong?

[Neal B. <ndb...@gm...>]

OK, back to my previous test.  gccxml cvs is now updated so the problem I 
reported last week is fixed (thanks!)

But still no luck.  Any hints?  (I have to say pyplusplus error messages could 
probably be more helpful)

gccxml now runs without errors.

But I get this:
parsing files - started
Reading project files: file by file
Reading source file: [hello_world.hpp].
File has not been found in cache, parsing...
 Command line for GCC-XML: /usr/bin/gccxml  -I"." -I"/usr/local/src/boost.cvs"

This is from 'generate_code.py', which is this:
import os
#from environment import settings
from pyplusplus import module_builder

mb = module_builder.module_builder_t(
        
files=['hello_world.hpp'],include_paths=['/usr/local/src/boost.cvs'],compilation_verbose=True
)

Here is hello_world.hpp:

Well, you are right messages could be much better.  In most cases they are.
In your case, I did not expect this code to fail. I guess this is
because of your
version of GCCXML. I will look at it.

Thanks for bug reporting.

It is a problem in 
(Pdb) n
> /usr/lib64/python2.4/site-packages/_xmlplus/sax/__init__.py(31)parse()
-> parser.parse(filename_or_stream)
(Pdb) n
KeyError: <exceptions.KeyError instance at 0x2aaab05c7dd0>

Something sax doesn't like.  Not sure how to debug it, one thing does look 
strange in the xml file:
  <File id="f55" name="/usr/include/c++/4.1.0/cstring"/>
  <File id="f56" name="&lt;internal&gt;"/>
  <File id="f57" name="/usr/include/c++/4.1.0/ext/new_allocator.h"/>

Anyway I put the xml here:

Neal, I found the problem.
Description: GCC-XML changed serialization of unnamed declarations (
enums + namespaces )
In previous version of GCC-XML, an element, that describes the
declaration has attribute "name" with some content. Now it does not
have this attribute.

By the way, it was nothing wrong with SAX, but with my code. pygccxml
uses SAX to
parse XML files. It gaves huge speed improvement.

The fix is simple:
file pygccxml/parser/scanner.py

search and replace next string
attrs[ XML_AN_NAME ]
with
attrs.get( XML_AN_NAME, '' )

Or you can replace the file with one I attach with this mail.

Thanks!

I replaced scanner.py in pygccxml source, ran python setup.py build + install, 
but the same problem is still there.  I confirmed that scanner.py is updated.

I run all tests I have.
Can you run unittests? You have unittests dir. Within this directory
there is file "autoconfig.py"
Please adjust the settings and run next command:

python test_all.py

Only 2 tests should fail.

Also can you debug the problem?

Thanks

[Roman Y. <rom...@gm...>]

Neal, I found another set of problems with GCCXML. I will fix
pygccxml/pyplusplus
and will send the patches to the list.

Sorry for inconvenience

[Roman Y. <rom...@gm...>]

I hope this time I provides almost complete fix for the bug.
Description:

First of all I missed some index operator on attrs - in Python
function, that read C++ function
declaration.
So what happened? For some constructors GCC-XML does not generates
"name" attribute.
I guess he does it for compiler generated constructors or may be for
something else.
I still need to find out. Until now about the problem. Now about a solution=
.

The solution consist from 2 parts:
1. to modify scanner_t.__read_calldef function:
    calldef.name =3D attrs[ XML_AN_NAME ] =3D=3D> calldef.name =3D
attrs.get(XML_AN_NAME, '')
2. to modify linker_t.visit_class member function. In this function,
for unnamed constructors
    pygccxml will assign class name.

So why almost? Because I want to play on safe-side :-)

Neal, please try it and report the problems.

Thanks!

At least the previous test now runs to completion.  Now on to bigger tests...
