Re: [DynInst_API:] Deleting snippets

[Marc BrÃnink <marc@xxxxxxxxx>]

Hi,

I think I never got an answer to this one, did I?
-> Is it safe to delete snippets while a thread is executing them?

I suppose not. BPatchAddressSpace::deleteSnippet also seems to support the âno, not safeâ assumption.

So what is the best practice to delete a snippet?
Currently I just disable them using a flag. 

To actually delete them the way forward seems to be to 
1. Disable the snippet
2. Queue them for deletion
3. Wait until I get lucky enough that no thread is actually executing the snippet.

#3 might never happen, though.

So how to delete snippets?
