We've had a number of errors reported from our previous
model filter implementation. This simplifies the impliementation
using a simple cross-reference structure with GSequenceIter in
both sequences.
We try extra hard to not emit signals when doing invalidation.
The lib/ directory was getting a bit out of hand, so this tries
to organize things a bit so it is easier going forward to locate
the code people want to patch.
This gives us the ability to locate symbols by directory in a much more
maintainable manner. Library consumers can adjust their location based
on where they know symbols are likely to be located.
This is a simple cache that keeps x,y pairs for use when drawing
visualizers. To keep this generic, and save on memory, we simply
store the x,y coordinates as floats between 0.0 and 1.0. This
saves us roughly 50% on each data point over the 2 8-byte
numbers we would otherwise store.
Obviously, we could take this further and make some fancy index
storage with run-length-encode values, but this should work for
now and allow us to get more exotic later.
This is a major redesign a modernization of Sysprof. The core data
structures and design are largely the same, but it has been ported to
Gtk3 and has lots of additions that should make your profiling experience
smoother. Especially for those that are new to profiling.
There are some very simple help docs added, but we really need the
experts to come in and write some documentation here.
