* Use an internalClass to represent formals and locals in CallContextsLars Knoll2013-12-041-13/+20
| | | | | | | | | | formals and locals in a CallContext where so far accessed through a linear search in ExecutionContext::getProperty. Fix this by introducing an internalClass for the Function used by the call context. Change-Id: I1141efa12b19d6de4a354bfd6e769c5ffcb8898b Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>
* Remove unused inline wrapperLars Knoll2013-12-041-1/+1
| | | | | | | | | The wrapper method for Function::code() was still there from the times we used C++ exceptions. It's not needed any more, so get rid of it. Change-Id: I2ec25fbca71eeef9d7a94a38b5adfa42e4de3a84 Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>
* V4 debugging: fix step-over and step-out.Erik Verbruggen2013-11-141-11/+14
| | | | | | | | | | | | | | | | - step-out: only stop if we’re leaving the context for the function we previously stopped at, so intermediate calls between the current position and the end do not stop the engine - step-over: set breakpoints on all lines in current function and continue to run. When hitting a breakpoint, see if we are in the same context, because recursive calls might happen. Breakpoints on all lines are needed, because the (pure) next line might be jumped over (like when doing step-over a single-line then clause, where the next line might be in the else clause).

* Refactor marking GC'ed objectsLars Knoll2013-11-051-4/+4
| | | | | | | | | | | Don't use recursive function calls anymore. Instead, push marked objects onto the JS stack, and then pop them off when their children are being marked. Should reduce stack memory usage, and improves performance by ~5%. Change-Id: I2d37d97579144fcba87ec8e9fd545dd220c01fbb Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>

* Prevent objects from being collected while in their constructorLars Knoll2013-09-221-4/+3
| | | | | | | | | | | | | While objects are being constructed, we don't have a reference to them on the JS stack yet. So the constructor needs to protect itself against being collected by putting the this object onto the JS stack. Added an environment switch MM_EXACT_GC to test exact garbage collection.

* Fix invalid reads with stringsSimon Hausmann2013-08-181-2/+2
| | | | | | | | | | | It may happen that a dynamically created compilation unit disappears before any QV4::Strings it created. Those strings would still have a reference to the QString data in the compilation unit. I don't see a choice other than making a copy of the string data ;(. But this patch adds a flag that would allow for avoiding it if we happen to know that the compilation unit data is static.
