This fixes an issue that shows up as a nice crash when "^R<enter>^C",
which is actually the event loop trying to call into a deleted object
(the search editor).
Move some more complex globals into a Singleton, which allows it being
used from global destructors. It solves problems where some global
variables, such as HashMaps may already be deleted, triggering crashes
trying to use them.
This allows adding and removing of asynchronous signal handlers while
executing signal handlers, even if it is for the same signal that is
being handled right now.
These changes are arbitrarily divided into multiple commits to make it
easier to find potentially introduced bugs with git bisect.Everything:
The modifications in this commit were automatically made using the
following command:
find . -name '*.cpp' -exec sed -i -E 's/dbg\(\) << ("[^"{]*");/dbgln\(\1\);/' {} \;
This patch moves the user account password hashes from /etc/passwd,
where they were world-readable, to /etc/shadow, where only root can
access them.
The Core::Account class is extended to support both authentication
against, and modification of /etc/shadow.
The default password for "anon" as of this commit is "foo" :^)
This was missing a "toInt32()" which returns 0 for NaN and Infinity.
From the spec:
6.1.6.1.2 Number::bitwiseNOT ( x )
The abstract operation Number::bitwiseNOT takes argument x (a Number).
It performs the following steps when called:
Let oldValue be ! ToInt32(x).
Return the result of applying bitwise complement to oldValue.
The mathematical value of the result is exactly representable as
a 32-bit two's complement bit string.
Fixes#4868.
Instead of doing a forced layout synchronously whenever an element's
style is changed, use a zero-timer to do the forced relayout on next
event loop iteration.
This effectively coalesces a lot of layouts and makes many pages such
as GitHub spend way less time doing redundant layout work.
Previously the client would only learn the mime type of what was being
dropped on it once the drop occurred. To enable more sophisticated
filtering of drag & drop, we now pass along the list of mime types being
dragged to the client with each MouseMove event.
(Note that MouseMove is translated to the various Drag* events in LibGUI
on the client side.)
If a widget accept()'s a "drag enter" event, that widget now becomes
the application-wide "pending drop" widget. That state is cleared if
the drag moves over another widget (or leaves the window entirely.)
We were using the "accept" flag on the event to break out of the
bubbling loop, but this had lasting consequences since all events that
bubbled too far came out looking as if someone had accepted them.
If an event is ignored by everyone, it should appear ignored.
These events allow widgets to react when a drag enters/leaves their
rectangle. The enter event carries position + mime type, while the
leave event has no information.
AT_SECURE is set in the auxiliary vector when we execute setuid/setgid
programs.
In those cases, we do not want to read environment variables that
influence the logic of the dynamic loader, as they can be controlled
by the user.
Previously, when trying to parse the location info of a member
variable, we asserted that the location info of its parent is of type
'Address'.
However, there are cases where we cannot compute the location info of
the parent (for example - because we do not yet support the type of
debug info generated for it).
In those cases, it is better to just leave the location info of the
member variable empty instead of crashing.
DebugSession now makes the loader stop after loading the libraries,
and parses the loaded libraries of the program before continuing its
execution.
DebugSession now also supports inserting a breakpoint at a given symbol
or source position.
Additionally, DebugInfo now takes the base address of its object into
consideration.
If set, the dynamic loader will perform a software breakpoint after
loading all libraries, and just before jumping to the main entry point.
This allows a debugger to inspect the loaded libraries before the
program starts executing.
This patch implements the "remove irrelevant boxes" and "generate
missing child wrappers" parts of table fixup.
"Generate missing parents" is left as a task for our future selves.
