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 allows us to have a sysroot different than /, so that we can resolve
symbols that are not necessarily installed on the system. For example, if
we are running an application in an alternate mount namespace, we will want
to resolve the symbols starting from the location of the checkout for that
namespace.
Generally alternate mount namespaces will have paths like "/newroot/usr/.."
so by setting the source to "/newroot/usr/" to "~/.local/" you can do
some fancy remapping.
When we see addresses in libgobject-introspection, give them the
"Introspection" tag to make it clear which library the symbol came from.
This is particularly useful since so many functions overlap with g_
prefixes.
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.
