Description Göran Uddeborg 2015-09-01 16:35:42 EDT
Description of problem:
When starting gdb, I get error messages about incorrect Python syntax in gdb-heap/heap/__init__.py

Version-Release number of selected component (if applicable):

How reproducible:
Every time.

Steps to Reproduce:
1. Create a file with debug information.  E.g.:
cat > c.c << EOF
int main()
  return 0;

2. Compile with debug information.
cc -g c.c -o c

3. Start gdb on it.
gdb c

4. Set a breakpoint.
b main

5. Run

Actual results:
Gdb prints an error message:
Traceback (most recent call last):
  File "/usr/share/gdb/auto-load/usr/lib64/ld-2.22.so-gdb.py", line 18, in <module>
    from heap.commands import register_commands
  File "/usr/share/gdb-heap/heap/__init__.py", line 58
    print 'type cache miss: %r' % typename
SyntaxError: invalid syntax

Expected results:
No error message.

Additional info:
To me, this looks very much like a python2/python3 issue.  The print statement is apparently in python2 syntax, but gdb links with the python3 libraries.

If I add parenthesis around the string and variable, I instead get an error message around the except clause two lines further down.  Again, it uses python2 syntax.

From what I can understand, a conversion 2to3 is needed on the Python files in the package.
