Turns out when we press yY, we get three events:
Qt.Key_Y, Qt.NoModifier
Qt.Key_Shift, Qt.ShiftModifier
Qt.Key_Y, Qt.ShiftModifier
If we don't ignore the second one, our keychain will be interrupted by the Shift
keypress.
Now that we don't rely on str(KeyInfo) being empty anywhere, there's no reason
to return an empty string for only-modifier keypresses anymore.
While those keys can't be bound (QKeySequence('Shift') == Qt.Key_unknown)
there's also no reason to explicitly ignore them.

This feels like fixing the symptom instead of the problem but I am not
sure how such a situation would arise. Never the less, the crash logs
clearly show that `_inject_userjs()` is being called with a deleted
frame sometimes. It is being called from a closure that gets triggered
on frame.loadFinished so I am not sure how frame could be deleted at
that time unless:
* the error message is misleading and it is actually some reference to
the object that is no longer valid
* the frame gets deleted from some other handler of loadFinished.
Previously to add a greasemonkey script you had to write it to the
greasemonkey data directory and call load_scripts(). Now you can just
make a new GreasemonkeyScript and pass it to add_script(), yay.
There are no users of the method yet although I could have used it while
writing the tests.
When `@require`ing local files (with the `file://` scheme) the
greasemonkey manager was not catching the DownloadItem.finished signal
because it was being emitted before it had managed to connect.
I didn't see this happening while testing with files that should have
been in cache but I wouldn't be surprised.
I had to change the download mock to be able to give it the appearance
of asynchronicity. Now when using it one must set download.successful
appropriately before firing download.finished. I also added a list of
downloads to the stub so a test could enumerate them in case the
unit-under-test didn't have a reference to them.
This is for the case where a script uses `@require` to pull down another
greasemonkey script. Since QWebEngineScript doesn't support `@require`
we pass scripts to it with any required ones pre-pended. To avoid
QWebEngineScript parsing the first metadata block, the one from the
required script, we indent the whole lot. Because the greasemonkey spec
says that the //==UserScript== text must start in the first column.
Apparently the currently available QtWebkit's javascript engine doesn't
support Object.entries[1]. It was only using that because I had copied
it from the official gm4 polyfill (maybe I should open an issue there?).
Tested with libqt5webkit5 version 5.212.0~alpha2-5 (debian) and I was
getting the same type of failures as Travis so it looks like this is the
case in arch too.

This is to support the non-interactive use case of setting a
`FileDownloadTarget` and passing auto_remove and not caring if the target
file exists or not.
An alternative to adding the attribute to `FileDownloadTarget` and
having set_target pull it out would be to add a new param to `fetch()`
and `set_target()`. But it would only be used for one target type
anyway.
Based on the gm4-polyfill.js script from the greasemonkey devs. But not
the same because that script doesn't work for us for a couple of
reasons:
* It assumes all GM_* functions are attributes of `this` which in
this case is the global window object. Which breaks it out of our iife.
It is possible to change what `this` is within the iife but then we
would have to do something weird to ensure the functions were available
with the leading `this.`. And I don't think user javascripts tend to
call GM functions like that anyway, that polyfill script is just making
weird assumptions and then claiming it'll work for "any user script
engine".
* It tries to provide implementations of GM_registerMenuCommand and
GM_getResource text which do unexpected thins or implement a circular
dependency on the new version, respectively.
The greasemonkey spec states that user scripts should be able to put the URL
of a javascript source as the value of an `@require` key and expect to have
that script available in its scope. This commit supports deferring a user
script from being available until it's required scripts are downloaded,
downloading the scripts and prepending them onto the userscripts code before
placing it all in an iffe.
TODO:
* should I be saving the scripts somewhere else? Maybe the cache dir?
The are just going to data/greasemonkey/requires/ atm.
