The save panel adjustment has been kept and modified a bit to position the
window nicely. It too uses the BWindow::CenterIn() method that adjusts based
on the screen edges.
BAlert::AlertPosition() has been superceded by the new BWindow method and should
be considered deprecated. Note that the alert position is not in the direct center of the
screen, it is offset vertically like before.
* These methods now return the new point after centering.
* But more importantly CenterIn() does some new adjustments to keep the window
position inside the screen edge. If you pass the screen frame into CenterIn()
it skips these adjustments.
* moved the inlined BRect constructor of IntRect to the cpp file. GCC will inline the method
anyway.
* impacted methods were both AGGTextRenderer::RenderString() in
src/servers/app/drawing/Painter/AGGTextRenderer.cpp, calling the StringRenderer constructor
with a BRect reference.
* unless someone comes up with an explanation, I'll try to come with a smaller testcase to
submit this problem upstream.
Return as many dirents as fit into the provided buffer. The readdir()
implementation in libroot tries to get many dirents and caches them to
reduce the amount of syscalls and the associated overhead.
This reduces the syscall count dramatically for use cases where a lot
of directories are enumerated. A "git status" on a Haiku repository for
example goes from over 50k read dir syscalls down to just under 7k.
The performance gain is only around a moderate 5% in that use case
though.
This usually wasn't a problem as the key buffer is generally large
enough to hold a single value. Still on short buffers or very long
it could have silently overrun before.
This replaces waiting a fixed time of 300ms for the device power to
stabilize. In the ideal case this reduces the boot time by 200ms per
connected device (including internal hubs).
This is very similar to what Linux implements and we use the same time
values. An interval of 25ms is used to check for connection state
changes, the stable time is at least 100ms as per the USB specs and the
whole process times out after 1.5 seconds.
- Sometimes the return type doesn't appear to have a
an associated byte size attribute. If so, simply
revert to using the architecture's register width,
since at least empirically all such cases appear
to be primitive types that fit into one anyways.
- If a node was already expanded, and we then removed/replaced
its children, those wouldn't automatically get their value nodes
added. Consequently, value retrieval for them would fail until
the parent was collapsed/re-expanded. If we encounter such a
model node when receiving a value request, notify the table model so
it can construct the value node appropriately.
- When removing a value node in response to ValueNodeChildrenDeleted,
we need to recurse down and ensure that each node's children are
likewise notified/removed. Otherwise we end up with deleted child
nodes in the node table, which in turn led to potential crashes when
either adjusting a node's type and/or its visible array range.
- Objects that act as ranged containers now expose a menu option
which allows the user to input a comma-separated list of ranges to
show. These need not be contiguous, ergo one can show only
the first and last elements of an array, or some random set of
indices in the middle as well.
Apparently it isn't ready yet. I haven't found a single syslog on Trac
that shows a successful initialization of the driver, and on my
machine, where it does that at least, the system freezes during boot.
