Allow everything to be built from the top level directory with just
'make', cleaned with 'make clean', and installed with 'make
install'. Also support these in any particular subdirectory.
Specifying 'make VERBOSE=1' will print each ld/g++/etc. command as
it runs.
Kernel and early host tools (IPCCompiler, etc.) are built as
object.host.o so that they don't conflict with other things built
with the cross-compiler.
The "Invert tree" checkbox was accidentally defaulted to display true when the actual tree wasn't being inverted, causing the checkbox to say the opposite of the tree state initially. This change just brings the visual indicator in line with what the code is actually doing.
Inverting the tree turns all of the innermost stack frames into roots,
allowing them to accumulate their total sample counts with other
instances of the same frame being innermost. This is an essential
feature of any cool profiler, and now we have it. :^)
Instead of fetching these from JSON in every paint event, we now have a
separate "SampleData" vector that can be iterated.
This optimization was made possible by profiling ProfileViewer and then
analyzing the profile with ProfileViewer! :^)
You can now select the time range you want on the profile timeline.
The tree view will update automatically as you alter the range.
Unfortunately this causes the treeview to collapse all of its nodes.
It would be nice to solve this somehow in the future so that nodes
can stay open.
We begin with a simple treeview that shows a recorded profile.
To record and view a profile of a process with <PID>, simply do this:
$ profile <PID> on
... wait while PID does something interesting ...
$ profile <PID> off
$ cat /proc/profile > my-profile.prof
$ ProfileViewer my-profile.prof
Make the results of a "find in files" operation look a lot nicer by
presenting them in a table format, instead of in a single-column list.
Since we don't yet support rich text in table view cells, use the
marker glyphs in the system default fixed-width font to show where the
matched text begins and ends on the line we found it on. :^)
Using int was a mistake. This patch changes String, StringImpl,
StringView and StringBuilder to use size_t instead of int for lengths.
Obviously a lot of code needs to change as a result of this.
This patch introduces code generation for the WindowServer IPC with
its clients. The client/server endpoints are defined by the two .ipc
files in Servers/WindowServer/: WindowServer.ipc and WindowClient.ipc
It now becomes significantly easier to add features and capabilities
to WindowServer since you don't have to know nearly as much about all
the intricate paths that IPC messages take between LibGUI and WSWindow.
The new system also uses significantly less IPC bandwidth since we're
now doing packed serialization instead of passing fixed-sized structs
of ~600 bytes for each message.
Some repaint coalescing optimizations are lost in this conversion and
we'll need to look at how to implement those in the new world.
The old CoreIPC::Client::Connection and CoreIPC::Server::Connection
classes are removed by this patch and replaced by use of ConnectionNG,
which will be renamed eventually.
Goodbye, old WindowServer IPC. You served us well :^)
Previously it was not possible to see what each thread in a process was
up to, or how much CPU it was consuming. This patch fixes that.
SystemMonitor and "top" now show threads instead of just processes.
"ps" is gonna need some more fixing, but it at least builds for now.
Fixes#66.
Client-side connection objects must now provide both client and server
endpoint types. When a message is received from the server side, we try
to decode it using both endpoint types and then send it to the right
place for handling.
This now makes it possible for AudioServer to send unsolicited messages
to its clients. This opens up a ton of possibilities :^)
While you are typing in HackStudio, we re-lex the C++ as you type,
so this means we also need to keep re-checking for matching curlies and
parentheses at the cursor.
Fixes#769 (although it's not optional, because it's too cool. :^)
This works for C++ syntax highlighted text documents by caching the C++
token type in a new "arbitrary data" member of GTextDocumentSpan.
When the cursor is placed immediately before a '{' or immediately after
a '}', we highlight both of these brace buddies by changing their
corresponding spans to have a different background color.
..and spans can also now have a custom background color. :^)
I originally put it in FormWidget because CursorTool was clueless about
painting. This patch adds Tool::on_second_paint() which allows all the
tools to hook into the second paint pass.
This patch implements basic rubber-banding. Perhaps this mechanism can
be generalized somehow, but it's not clear to me how that would work
at the moment.
The Shell also puts each command into its own process group,
which interferes with us trying to do the same here. We don't
really need the shell here anyway, but it means we'll have to
do command splitting ourselves.
This patch adds pthread_create() and pthread_exit(), which currently
simply wrap our existing create_thread() and exit_thread() syscalls.
LibThread is also ported to using LibPthread.
You can now manipulate the widget selection either by clicking and
dragging the widgets using the cursor tool, or by interacting with
the form widget tree view. :^)
Using the default cursor bitmap as the cursor tool icon in HackStudio
was predictably making it impossible to tell if it's the real cursor
or not. Replace it with a color-inverted cursor. :^)
We now use the magical widget registry to factory-construct widgets and
place them into the form.
This will need all kinds of work, but it's nice that the mechanism is
working as intended.
