Bug 11533 - Code::Blocks History

Bug #11533 2007-07-10 13:09

New class browser crash

Related to the switch-file crash.

Windows XP, rev. 4238.

Steps to reproduce:

1. Start up codeblocks. The codeblocks.cbp should be opened by default. Some of the files in the project should also be open.

2. Switch to the symbols tab. Wait until the class browser is updated.

3. Move the scrollbar to the bottom.

4. Switch the scope to "Current file"

5. While the class browser is still blank, click the "scroll up (up arrow)" button above the scrollbar. CRASH.

I could replicate the crash using this procedure more than 5 times.

(As a side note, in my development branch this bug doesn't appear - the nodes are removed too fast to be able to reproduce the bug - I'll copy the RemoveInvalid nodes function from my development branch to the trunk and see if they solve this bug)

Update: After I recompiled with my version of RemoveInvalidNodes, i managed to get rid of the 8-second delay when deleting the nodes, so to reproduce the bug I had to be really fast and tricky, put the mouse on the "up arrow" button and change the scope with the keyboard (it won't happen accidentally, that's for sure). However, the bug was STILL reproduced. :(

Fixed!

In ClassBrowserBuilderThread::BuildTree()

m_pTreeTop->Hide();

m_pTreeBottom->Hide();

m_pTreeTop->Freeze();

m_pTreeBottom->Freeze();

and on the exit parts:

m_pTreeBottom->Thaw();

m_pTreeTop->Thaw();

m_pTreeBottom->Show();

m_pTreeTop->Show();

This solves the bug. It also ensures that the user won't be able to click on any item during tree construction, so it's a clear indicator that the tree is non-functional during construction :)

Fixed and committed :)
