I’ll try harder to write the reports then. One additional benefit they have is that I take the opportunity to read threads/bugzillas which I originally skipped, so this is beneficial to me too.

I like the idea of monthly reports, but it is not easy to keep it rolling during the time… we always have several others activities to do (and blogs are not the first ehehehe).

However, I think it is a good idea and I’m glad to read it always.

The U3 is good. I have one of the very few iriver T10 that made it into Argentina. (http://iriverinc.com/support/ultra/)

O melhor resumo disso foi o que eu escutei de um amigo que faz mestrado de economia na usp, “poker de gente grande onde as fichinhas é a cadeia produtiva do mundo”.

Só para constar o Nassif agrega textos de terceiros no blog dele, que por sinal é muito bom.

Você sabe o nome daquele artista que contou o ” causo ” do cinema?
Muito engraçado, foi levado no último programa do Sr. Brasil.
Gostaria de rever , mas no You tube não encontrei.

But it’s true that GDB is lagging behind from other debuggers in terms of features. Lately, the GDB community has been regaining development speed, so perhaps we can catch up.

This shows one more time that the Open Source community copies ideas from others more often than invent new stuff.

Although generating expression string and passing it to gdb.evaluate() looks little ugly, if it will work then I am happy with it.

What I tried was to print all elements in an AVL tree using python scripting.
The equivalent gdb user command(not working) is given below. Although the following command to specific to my project, I hope it will better explain my requirement.

define descriptor
set $arg0 = (VM_DESCRIPTOR_PTR)$arg0
if ! IS_AVL_TREE_LEFT_LIST_END( $arg0->tree_node )
set $left = STRUCT_ADDRESS_FROM_MEMBER( (AVL_TREE_PTR)AVL_TREE_LEFT_NODE( &$arg0->tree_node ), VM_DESCRIPTOR, tree_node)
descriptor $left
end
printf “%3d %10p %10p %10p %4d “, $arg0->reference_count, $arg0->start, $arg0->end, $arg0->unit, ($arg0->end-$arg0->start)/PAGE_SIZE
vm_prot &$arg0->protection.user_write
printf “\n”

if ! IS_AVL_TREE_RIGHT_LIST_END( $arg0->tree_node )
set $right = STRUCT_ADDRESS_FROM_MEMBER( (AVL_TREE_PTR)AVL_TREE_RIGHT_NODE( &$arg0->tree_node ), VM_DESCRIPTOR, tree_node)
descriptor $right
end
end

In the above example, IS_AVL_TREE_LEFT_LIST_END(), IS_AVL_TREE_RIGHT_LIST_END(),STRUCT_ADDRESS_FROM_MEMBER(),AVL_TREE_LEFT_NODE(), AVL_TREE_RIGHT_NODE() are macros. If gdb.evaluate() is implemented then I can use that function to execute/expand these C macros inside gdb get the value back into python.

http://sourceware.org/gdb/wiki/PythonGdb says – Breakpoints, blocks, frames, symbols, symbol tables, types, and values have Python representations. That means I can represent a C type inside python?

I would be very helpful, if you can write a small documentation for the existing work.

Thank you very much for the good effort.

Do you mean storing an expression and then being able to eventually ask it to be evaluated by GDB? If so, would it solve your problem if you could store an expression as a string, and then pass it to a gdb.evaluate() function which would return a value for it?

If so, we can add such function, it should be easy. If not, what functionality would you need out of a python representation of an expression?

Thanks for your feedback, this is exactly the kind of input I need at this point.

On the bright side, what we already merged into mainline GDB will appear in GDB’s weekly snapshot tarball. Though for now I admit there’s nothing useful there regarding Python support (as I mentioned in this post).

…that page contains no links to the git repo, from what I can tell. A search for PythonGDB brings up nothing useful for that page. A search for gdb-python brings up the git repo, at least. This is an extraordinarily interesting project, but you guys need to do some PR work. =)

In the case of my post it’s the GNU Compiler Collection, which is an important tool for software development (to put it in layman terms).

According to Google, it can also be:

Gulf Cooperation Council
Global Corporate Challenge
General Chiropractic Council
Grace Community Church

Among others.
