Thread-safety issue in cmake support ?

[David Nolden]

The big lock wouldn't eliminate multithreading at all.

For example in the c++ support, it is needed only once at the beginning of a
parse job to get the include paths, and maybe a few times during the code
completion, which is quite tightly coupled to the UI anyway. Ok, it would
also be required for using the new smart-ranges for highlighting, but that
could be combined into one single locking per parsed open document, and thus
wouldn't be critical.

The important task is just to make sure the lock is used as seldomly as
possible, and to make sure that all the heavy-lifting is done in a long
continuous phase without the lock. That is easy for c++ support at least.

Greetings, David

Both can be done in parallel, actually. If a BKL were implemented, it would
then be possible to walk around and eliminate each usage of it (except in
the
main thread)
