Subject [jira] [Commented] (THRIFT-4124) Connection to non-thrift server crashes android app
Date Wed, 27 Nov 2019 21:45:00 GMT

    [ https://issues.apache.org/jira/browse/THRIFT-4124?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16983951#comment-16983951

Qinghui Xu commented on THRIFT-4124:
------------------------------------

Have a quick look at THRIFT-5021 and it seems it is currently implemented (only?) for .net
core
I create a ticket for adding a doc (THRIFT-5037) and a ticket for the support in java binding
(THRIFT-5038).
I will be happy to work on that with the community (I could provide patches or review if other
people contribute a patch).

>             Project: Thrift
>          Issue Type: Bug
>          Components: Java - Library
>    Affects Versions: 0.10.0
>         Environment: Android Studio
>            Reporter: Alexey Andronov
>            Assignee: Qinghui Xu
>            Priority: Major
>              Labels: async

> I connect to server like this:
> {code}m_client = new DispatchBackend.AsyncClient(
>     new TBinaryProtocol.Factory(),
>     new TAsyncClientManager(),
>     new TNonblockingSocket("google.com", 80)
> );{code}
> Then I execute request:
> {code}
> try {
>     m_client.request();
> } catch (TException e) {
>     // never reaches here
> }{code}
> And my app crashes with OOM error.
> The problem is that I can't catch exception from thrift library inside my application
i.e.
> inner library exception always crashes my app which is very sad.
> P.S. I tried to catch Throwable instead of TException and it didn't help
> Stacktrace:
> {code}E/art: Throwing OutOfMemoryError "Failed to allocate a 1213486172 byte allocation
with 3514240 free bytes and 122MB until OOM"
> E/AndroidRuntime: FATAL EXCEPTION: TAsyncClientManager#SelectorThread 9112
>    Process: com.myapp, PID: 20608
>    java.lang.OutOfMemoryError: Failed to allocate a 1213486172 byte allocation with 3514240
