The "Step Out" action continues execution until the current function
returns.
Also, LibDebug/StackFrameUtils was introduced to eliminate the
duplication of stack frame inspection logic between the "Step Out"
action and the BacktraceModel.
We can now step into library code in the debugger.
Since we now need the whole source code of our libraries
(and not just the headers), we clone the whole serenity git repo into
/usr/share/serenity.
Previously, we did source-level singlestepping by inserting a
breakpoint at every source line and continued execution until we hit
a breakpoint. We did this because we used to not generate source
locations debug info for library code, and it allowed us to not single
step through lots of library code to get to the next source line
(which is super slow).
Since we now do generate source locations debug info for libraries
(-g1), we can improve the way we implement source level stepping by
stepping at the assembly level until we reach a different source code
location.
This also resolves some typing issues that only 'accidentally' worked, like declaring
a function to return type A, and the definition actually returning type B (which works
if type B is a subtype of type A). I like to call these "ninja imports".
To prevent problems like this in the future, I put all globals in a HackStudio.h.
I'm not sure about the name, but main.h and common.h felt wrong.
Since the vast majority of message boxes should be modal, require
the parent window to be passed in, which can be nullptr for the
rare case that they don't. By it being the first argument, the
default arguments also don't need to be explicitly stated in most
cases, and it encourages passing in a parent window handle.
Fix up several message boxes that should have been modal.
Get rid of the weird old signature:
- int StringType::to_int(bool& ok) const
And replace it with sensible new signature:
- Optional<int> StringType::to_int() const
This patch adds a context menu to variables in the debugger variable
tree view that has an option to set the value of a variable. An input
box will pop up asking for the new value of the variable, which
is then parsed and used to set the actual variable.
.. and make travis run it.
I renamed check-license-headers.sh to check-style.sh and expanded it so
that it now also checks for the presence of "#pragma once" in .h files.
It also checks the presence of a (single) blank line above and below the
"#pragma once" line.
I also added "#pragma once" to all the files that need it: even the ones
we are not check.
I also added/removed blank lines in order to make the script not fail.
I also ran clang-format on the files I modified.
