Subject: ecore_con/ecore_ipc: flush should wait for connection.
X-Git-Tag: upstream/1.20.0~2797
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a7657e821f81eab59a719c81d3994194492476a6;p=platform%2Fupstream%2Fefl.git

ecore_con/ecore_ipc: flush should wait for connection.

Some applications will create the handle, immediately send data, flush
and delete it, expecting the data to be sent to remote peer.

This is a bad behavior as the application would become unresponsive
until the connection is established, data can be written (since
depends on server consuming it), then allow it to be closed.

A proper behavior here would be to chain based on events, with the
usage of a copier would be simply wait for "done" event.

However the legacy API allowed this and terminology depends on this
awkward "feature", thus be bug-compatible.

This fixes T5015.
