6045 callback error

[ssaraf]

Hi,

I am getting error calling success callback using bindonce

CefCreateClosureTask(base::BindOnce(
&Callback::Success,
callback,
responseJson
));

Can we see the sample usage of how the success callback can be called after the current changes ?

[ssaraf]

Is there any change for this?

[magreenblatt]

Please provide a complete code example.

[ssaraf]

void OnSuccess(const CefRefPtr<Callback>& callback, const std::string& responseJson) noexcept {
if (CefCurrentlyOn(TID_UI)) {
return callback->Success(responseJson);
}

CefCreateClosureTask(base::BindOnce(
&Callback::Success,
callback,
responseJson
));

CefPostTask(TID_UI, task);

}

[magreenblatt]

What is the declaration of Callback::Success? Also, |task| is an undefined variable in your code.

See https://bitbucket.org/chromiumembedded/ ... ting-tasks

[ssaraf]

Task is defined before, failure callback works normally without any change/error from previous versions.

[magreenblatt]

The success callback can be called from any thread. You don't need to post it to the UI thread.

So the issue is:
In case of failure callback this works -

void OnFailure(const CefRefPtr<Callback>& callback, const std::string& errorJson) noexcept {
constexpr int errorCode = -1;
if (CefCurrentlyOn(TID_UI)) {
return callback->Failure(errorCode, errorJson);
}

CefRefPtr<CefTask> task = CefCreateClosureTask(base::BindOnce(
&Callback::Failure,
callback,
errorCode,
errorJson
));

if (!CefPostTask(TID_UI, task)) {
ATLAS_LOG(AtlasLog::ERR) << "Unable to post failure callback task";
}
}

But for success -

void OnSuccess(const CefRefPtr<Callback>& callback, const std::string& responseJson) noexcept {
if (CefCurrentlyOn(TID_UI)) {
return callback->Success(responseJson);
}

CefRefPtr<CefTask> task = CefCreateClosureTask(base::BindOnce(
&Callback::Success,
callback,
responseJson
));

if (!CefPostTask(TID_UI, task)) {
ATLAS_LOG(AtlasLog::ERR) << "Unable to post success callback task";
}
}

I see the below errors starting v6045

Hi, we see a similar issue. How can we use success callback with UI_Thread?

[ssaraf]

The success callback can be called from any thread. You don't need to post it to the UI thread.

Is there a way to do it through UI thread like it was done before ? Can you give an example for success callback with UI thread ?
