No obvious logging to suggest anything was closing down Ktor version 1 2 4

rocketraman · Answer

I ve had that too but never figured out why it was happening

rocketraman · Answer

Not having time to debug that I ended up switching to the CIO client Which has its own issues but seems to generally work well

Jonathan Mew · Answer

Thanks < rocketraman> this is the first time I ve seen it but haven t been using it long That makes me a bit nervous about using the Apache client in production anyone got any idea what could have happened

Jonathan Mew · Answer

I was assuming the Apache client would be pretty well tested and widely used

rocketraman · Answer

If you google that error all you really find is that the Apache client should never get into that state So its almost certainly a problem with how Ktor is using it

rocketraman · Answer

I ve used the Apache client on its own pretty extensively and never had that issue

Jonathan Mew · Answer

Yeah likewise would be interested in hearing from people who do use the Apache client or whether others have hit the same error

Jonathan Mew · Answer

Can t see an open issue on Github either

Jonathan Mew · Answer

Ugh Was just me being stupid disappointed closed the issue

rocketraman · Answer

> I had passed an HttpClient instance rather than the provider and was trying to reuse a single instance Just curious into what The `Apache` object into the `HttpClient` constructor function

Jonathan Mew · Answer

I have a DAO and pass it a client provider lambda It creates a client while handling a particular request and uses it to make one request itself calling httpClient use which closes the client I pass the lambda at construction so that test instances can use a test HttpClient implementation which doesn t send any request But instead of passing the provider I passed the instance a refactoring fail But the client would work for one call so wasn t immediately obvious it was broken

rocketraman · Answer

Ah ok thanks for the explanation I don t believe that was my situation but since I haven t used the Apache client in months I d have to go spelunking through our git history to check
