Subject: [PATCH] HTTP2: Delay any communication until encrypted() can be responded to
|
||||
|
||||
We have the encrypted() signal that lets users do extra checks on the
|
||||
established connection. It is emitted as BlockingQueued, so the HTTP
|
||||
thread stalls until it is done emitting. Users can potentially call
|
||||
abort() on the QNetworkReply at that point, which is passed as a Queued
|
||||
call back to the HTTP thread. That means that any currently queued
|
||||
signal emission will be processed before the abort() call is processed.
|
||||
|
||||
In the case of HTTP2 it is a little special since it is multiplexed and
|
||||
the code is built to start requests as they are available. This means
|
||||
that, while the code worked fine for HTTP1, since one connection only
|
||||
has one request, it is not working for HTTP2, since we try to send more
|
||||
requests in-between the encrypted() signal and the abort() call.
|
||||
|
||||
This patch changes the code to delay any communication until the
|
||||
encrypted() signal has been emitted and processed, for HTTP2 only.
|
||||
It's done by adding a few booleans, both to know that we have to return
|
||||
early and so we can keep track of what events arose and what we need to
|
||||
resume once enough time has passed that any abort() call must have been
|
||||
processed.
|
||||
|
||||
Fixes: QTBUG-126610
|
||||
Pick-to: 6.8 6.7 6.5 6.2 5.15 5.12
