------------------------------------------
Summary: Make sure the local console is fully working before the
user can type commands
Key: KARAF-1640
URL: https://issues.apache.org/jira/browse/KARAF-1640
Project: Karaf
Issue Type: Bug
Reporter: Christian Schneider
Fix For: 3.0.0
The console bundle starts early as it contains jline, gogo and karaf specific
console interfaces and tools that all commands need.
The problem with this is that the user can start typing commands before all
commands are started. So it can happen that a command is not available at that
point. This leads to (from the user point of view) errors in completion and
when executing commands.
So the idea is to still start the console bundle early but make sure the shell
is only opened when all commands are started.
As commands often use blueprint to startup we can not simply check the bundle
status as it will be active before the commands are activated.
So one option to improve the situation is to split the shell starting from the
rest of console and do it in a separate bundle with a high start level. So most
of the commands would be present. Still because of the blueprint startup we
could miss some bundles.
Another option is to start a thread that somehow watches the start of the
bundles and that opens the shell when all bundles are really active. We could
use the new status checking from the bundle module that also can watch
spring-dm and blueprint status. The advantage with this aproach is that we
could display the live startup status while waiting.
We could also allow the user to press e.g. enter to open the console at any
point.
So for example we could show something like this:
Karaf startup ...
Press Enter to open a shell now
Bundles started (11/78), 3 failures
