Subject: Let the request processor handle the exceptions
X-Git-Tag: v1.31.0~27
X-Git-Url: https://gerrit.simantics.org/r/gitweb?a=commitdiff_plain;h=8a609b2a6559fef3d2f21224253d87c414473187;p=simantics%2Fplatform.git

Let the request processor handle the exceptions

Prior to this failed write transactions were not cancelled. For
consistency the read transactions are now handled the same way.
Also deprecated legacy implementations.

refs #7633
