Add a MappedROM::find_chunk_starting_with() helper since that's a very
common usage pattern in clients of this code.
Also convert MultiProcessorParser from a persistent singleton object
to a temporary object constructed via a failable factory function.
This patch adds a MappedROM abstraction to the Kernel VM subsystem.
It's basically the read-only byte buffer equivalent of a TypedMapping.
We use this in the ACPI and MP table parsers to scan for interesting
stuff in low memory instead of doing a bunch of address arithmetic.
For singly-indirect blocks, "callback" is just "add_block".
For doubly-indirect blocks, "callback" is the lambda function
iterating on singly-indirect blocks: so instead of adding itself to the
list, the doubly-indirect block will add all its childs, but they add
themselves again when they run the callback of singly-indirect blocks.
And nothing adds the doubly-indirect block itself :(
This leads to a double free of all child blocks of the doubly-indirect
block, which is the failed assert described in #1549.
Closes: #1549.
This patch adds a GetterSetterPair object. Values can now store pointers
to objects of this type. These objects are created when using
Object.defineProperty and providing an accessor descriptor.
If a model doesn't specify a text alignment for a given field, we now
fall back to CenterLeft. This will look better than Center in the vast
majority of cases.
If the cursor happened to be blinking in the invisible state, it would
take 500ms before we actually see the cursor in a newly focused editor
widget. This patch makes it show up right away.
Right now the default is an empty value, which we accidentally exposed
in set{Interval,Timeout}() by not providing a custom this value, which
should't happen at all. Let's just make it a required argument instead.
You can now pass a dictionary of request headers when starting a new
download in ProtocolServer.
The HTTP and HTTPS protocol will include the headers in their requests.
To achieve this, the API was tweaked a bit to allow for easier tracking
of completions.
This API change is non-disruptive to any application that does not use
anchored styles.
This commit also adds the concept of "anchored" styles, which are
applied to a specific part of the line, and are tracked to always stay
applied to that specific part.
Inserting text in the middle of an anchored style extends it, and
removing the styled substring causes the style to be removed as well.
Apparently that's allowed and the RFC is just unclear about it.
Some servers seem to zero-pad the chunk size for whatever reason, and
previously, we interpreted that as the last chunk.
