The toolchain builds just fine without the git repository (tested on
windows and linux). We can skip setting up the repo and apply the
patches directly when we aren't working on the toolchain itself. A
flag `--dev` has been added for cases when git repo is needed. Without
the flag, regular patch is applied. This significantly improves build
times for first time builds.
Implement the syntax and behavor necessary to support array literals
such as [...[1, 2, 3]]. A type error is thrown if the target of the
spread operator does not evaluate to an array (though it should
eventually just check for an iterable).
Note that the spread token's name is TripleDot, since the '...' token is
used for two features: spread and rest. Calling it anything involving
'spread' or 'rest' would be a bit confusing.
Previously we blindly just called update_next_timer_due() when
ever we modified the timer list. Since we know the list is sorted
this is a bit wasteful, and we can do better.
This change refactors the code so we only update the next due time
when necessary. In places where it was possible the code was modified
to directly modify the next due time, instead of having to go to the
front of the list to fetch it.
Now FileManager will paste the clipboard contents inside a folder if the
paste action was clicked through a folder context menu, being the target
directory the selected folder.
This mimicks most of the behaviours that the different file managers
have.
The public consumers of the timer API shouldn't need to know
the how timer id's are tracked internally. Expose a typedef
instead to allow the internal implementation to be protected
from potential churn in the future.
It's also just good API design.
Add a test case that the timeout argument to pthread_cond_timedwait
works in LibPthread. This change also validates the new support for
timeouts to the futex syscall, as that's how condition variables are
implemented.
Now that the futex implementation actually supports timeouts,
we can fix the LibPthread implementation of pthread_cond_timedwait
to support the timeout argument.
Utilize the new Thread::wait_on timeout parameter to implement
timeout support for FUTEX_WAIT.
As we compute the relative time from the user specified absolute
time, we try to delay that computation as long as possible before
we call into Thread::wait_on(..). To enable this a small bit of
refactoring was done pull futex_queue fetching out and timeout fetch
and calculation separation.
This change plumbs a new optional timeout option to wait_on.
The timeout is enabled by enqueing a timer on the timer queue
while we are waiting. We can then see if we were woken up or
timed out by checking if we are still on the wait queue or not.
The current API of add_timer makes it hard to use as
you are forced to do a bunch of time arithmetic at the
caller. Ideally we would have overloads for common time
types like timespec or timeval to keep the API as straight
forward as possible. This change moves us in that direction.
While I'm here, we should really also use the machines actual
ticks per second, instead of the OPTIMAL_TICKS_PER_SECOND_RATE.
Normally the storage would be expanded by set_shape() upon transition
to a new shape, but if the shape is already unique, there is no new
transition so we have to expand the storage manually.
It turns out "delete" is actually a unary op :)
This patch implements deletion of object properties, it doesn't yet
work for casually deleting properties from the global object.
When deleting a property from an object, we switch that object to
having a unique shape, no longer sharing shapes with others.
Once an object has a unique shape, it no longer needs to care about
shape transitions.
This allows us to start WebServer on a port other than 8000, or multiple
instances of it at the same time :^)
Also print out what port was being used in the end.
This is a special case that was previously not implemented.
The idea is that you can dispatch a signal to all other processes
the calling process has access to.
There was some minor refactoring to make the self signal logic
into a function so it could easily be easily re-used from do_killall.
The kill system call accepts negative pids, as they
have special meaning:
pid == -1 means all processes the calling process has access to.
pid < -1 means every process who's process group ID is -pid.
I don't see any reason why the user space program should mask this.
