----------------------------------------
Summary: Properly serialize multiple bundle installations
Key: FELIX-3523
URL: https://issues.apache.org/jira/browse/FELIX-3523
Project: Felix
Issue Type: Improvement
Components: Web Console
Affects Versions: webconsole-3.1.8
Reporter: Felix Meschberger
Consider an administrator wishing to install a number of interdependent bundles
through the Web Console. There are basically two options:
(1) Multiple requests with one bundle after the other. Problem is that
installation takes place asynchronously and there is no easy and direct
feedback on the installation. Thus sending successive requests must be timed.
Not nice.
(2) Send one single request with multiple bundlefile parameters. Unfortunately,
this does not work either, because each bundle is installed in its own thread.
Not nice.
I see two solutions:
(a) add an option requesting synchronous installation instead of background
installation. When using HTTP clients such as cURL such an option can easily be
used and leveraged because there is little chance of deadlocks (which lead to
the asynchronous installation in the first place)
(b) implement a proper queue for asynchronous installation such that the
installation of multiple bundles can be properly serialized. This would have
the added benefit of not creating a new thread for each installation.
Caveat for synchronization: If the Web Console itself is to be updated,
synchronous installation/update may fail. Such an implementation much take
precaution.
