Use a separate delete command for deleting text, because using regular
composition events for deleting text doesn't seem to work well in
Facebook comment boxes.
Turns out the Facebook comment box doesn't work well if we send
compositions alongside set/remove span events. This patch adds back the
update composition flag, but only sends composition when necessary,
which is only right before we send key events.
Because onImeUpdateComposition is no longer associated with a separate
action, it no longer sends back a reply using AutoIMESynchronize.
Expand RemoveIMEComposition with a flag to allow canceling the
composition. Also, remove the "ideographic space" hack from before
because it's no longer applicable (the test remains so we can catch
any regressions).
When a Gecko text change spans larger than our original request, we have
to do the replacement in parts in order to preserve any spans from the
original request. There was a bug where the selection is moved to the
wrong offset after the three replacements. This patch switches the order
of the two replacements and manually fixes up the selection.
For any text changes that originated on the Gecko side, this patch also
splits the replacement into two parts (delete + insert), so that old
composing spans are properly cleared first. This new behavior changes
the expected result for the test added by bug 1051556, so the test is
changed as well.. I think this new behavior is more correct, but if it
results in regressions, we can reevaluate.
Right now we send a "process-gecko-events" message to
GeckoInputConnection in order to wait on Gecko during testing. However,
now we have GeckoThread.waitOnGecko() to do that, so we can just use
that directly.
Under asynchronous IME, when we check text/selection for correctness, we
have to wait for the IC thread to sync the shadow text first. In order
to do that inside the assert methods, we have to move them to inside
InputConnectionTest, so that they can call processGeckoEvents() and
processInputConnectionEvents().
Also, ignore a single newline character, if present, at the end of the
actual text, because it's a side effect of some editing operations in
Gecko (e.g. clearing all text in an HTML editor).
When switching the IC thread from one thread to another, we can no
longer block on the old IC thread waiting for the Gecko thread. However,
we still block on the new IC thread, waiting for the old IC thread to
finish processing any old events.
Sync the shadow text to the current text when the selection or text
changes on the Gecko side, provided we are not in batch mode and if we
don't have pending actions. Otherwise, remember the skipped sync and
re-sync when we exit batch mode and/or finish all pending actions.
We used to flush the Java side text upon receiving the acknowledge-focus
event, at which point the Java side is waiting on the Gecko side.
Because of the async IME refactoring, we can no longer wait on the Java
side, so we have to flush the text early, before sending the first focus
notification. Also, the acknowledge-focus event is no longer needed as a
result.
Our call to InputMethodManager to restart input also has to changed due
to the change in calling sequence between notifyIME and
notifyIMEContext.
Due to async IME refactoring, we no longer need the blocking mechanism
in ActionQueue. As a result of the simplified code, we can remove
ActionQueue entirely and move its code to under GeckoEditable.
ActionQueue.offer() is now icOfferAction().
This patch also makes mText an instance of AsyncText, and change all
accesses to mText to reflect the new async interface, i.e. accesses on
the Gecko thread go through getCurrentText() and the current*** methods,
and accesses on the IC thread go through getShadowText() and the
shadow*** methods.
AsyncText keeps two copies of the text - the current copy on the Gecko
thread that is the authoritative version of the text, and the shadow
copy on the IC thread that reflects what we think the current text is.
When editing the text on the IC thread, the shadow copy is modified
directly, and then the modification is sent to the Gecko thread, which
modifies the current copy concurrently. Depending on what Gecko does to
the text, the current copy may diverge from the shadow copy, but
periodically, the shadow copy is synced to the current copy through
AsyncText.syncShadowText() to make the two copies identical again.
As part of async IME refactoring, we will no longer send composition
updates separately. Instead, composition updates will be integrated into
the set-span and remove-span events, similar to what we already do for
replace-text events.
GeckoEditable implemented GeckoEditableListener because GeckoAppShell
called its methods through GeckoEditableListener, but now we use JNI to
call GeckoEditable methods directly, so GeckoEditable no longer has to
implement GeckoEditableListener.
This change also lets us simplify GeckoEditableListener by making
onTextChange and onSelectionChange no longer have any parameters.
Currently, clearSpans calls are carried out immediately, but that makes
it out of order in relation to other calls, which have to go through
Gecko. This patch fixes this issue.
This removes the obsolete toolkit directory. A few references to dialogOverlay
have been updated to just used <dialog> directly. The InlineSpellCheckerUI var
has also been moved directly to browser.js and defined as lazy getter.
