8:33 a.m.
Max, Emanuel and I discussed the usability aspects of the cli today. We
agreed on the following:
1) drop the '/' prefix for the commands;
2) instead of '~' signifying the root node use '/';
3) instead of ',' as a node separator in the address (node path) use
'/'. so the format of an operation will look like
[node-type=node-name (/node-type=node-name)*] : operation-name
['('param=value (,param=value)*')']
This (2 and 3) will make the path look more linux-like, so hopefully
more friendly for an admin.
4) in the same spirit, the tab-completion for operations will start with
'./', e.g. './subsystem=web/connector=http:read-resource'
5) for the command names, Max likes
cn (change node) - current /prefix or /to.
cwn (current working node) - again current /prefix or /to w/o arguments.
I'd even go for cd to change the node. The reason I didn't add it
originally was 'directory' doesn't belong here. But cd is kind of habit
for this kind of thing, so I could add it as an alias.
Any objections or suggestions?
Thanks,
Alexey

How does this relate to the discussion of low-level commands vs high level?
Other than that question, what you describe here sounds fine (including
the 'cd' alias, which I know would be what I'd naturally use).

Other than that question, what you describe here sounds fine (including
the 'cd' alias, which I know would be what I'd naturally use).
It's basically a switch. In the current impl commands require '/' as a
prefix and operations don't require anything. Here it's the opposite.
Operations performed at the current level (prefix address) would require
':'.
Operations performed at a deeper level than the current one (if they
need to specify additional address part) would start with './' then the
address part, then ':' + operation name.
Or, if you want to start from the root node, you'll have to start with '/'.
Commands won't require any prefix.

Thanks. I realize now my question was stupid. "1) drop the '/' prefix
for the commands" tells me the answer pretty clearly!

How does this relate to the discussion of low-level commands vs high level?
It was a long discussion - but let me see if I can summarize what drove this.
There are some subjectivity in parts of this but mostly its driven by not making the
shell being "weird" compared to what users otherwise sees in the wild...thus /
is suggested as a separator to match filesystem and url paths.
When starting up the cli it also just feels so weird and wrong to require typing / to get
to a command
(unless of course you are an IRC guy - but thats not really the audience we cater to is it
?:)
Thus my suggestion was to make the logic so if you just type a string, i.e.
"help"
then it will mean "execute the command or alias named help" nothing else. Just
like a normal shell.
If you want to "execute" something in the current node/path you need to (just
like in a bash/zsh etc. without a PATH setup)
to put ./<path>:<operation> to execute it.
so the suggested syntax allow you to type things like:
jboss-admin.sh
$ connect
[/] # default connect is root.
$ cn subsystem=web
[/subsystem=web]
$ :read-resource-configuration #executing operation against current node.
$ ..:read-resource-configuration # executing against parent node (not sure if this should
actually be ../:read-resource-configuration?)
$ cn ../hosts=undefined/server=server1 # up one level and into the path.
[/hosts=undefined/server=server1]
$ /subsystem=web:read-resource-configuration # execute based on root ignoring the current
node
[/hosts=undefined/server=server1]
$ rr # a command/alias that will execute :read-reosource-configuration
<return the result>
We even discussed if it should be legal to do:
[/hosts=undefined/server=server1]
$ =server2:read-resource-configuration # execute the operation in context of current
nodetype, but change the name vs requiring eplicit typing.
$../server=server2:read-resource-configuration
With this tab completion still can know if it should be completing names, children or
operations AND we get a "navigational" syntax that mimicks well known paths.
We could even go all the way and allowed / instead of = you could actually copy the paths
directly between your curl/browser and the cli - only diff would be the operation syntax.
Hope that gave some more context - at least with these changes the CLI navigation
doesn't feel so alien to newbies...their brains can spend more
energy to actually understand the semantics of the operations than the syntax.

New subject: Recent jboss-modules' JAXP-related changes and JAXB impl
Hi,
after the latest changes in jboss-modules for loading our own set of
jaxp factories, I'm seeing some regressions in the jbossws-cxf testsuite
against AS7:
java.lang.ClassCastException: __redirected.__TransformerFactory cannot
be cast to javax.xml.transform.sax.SAXTransformerFactory

basically the JAXB impl expects the configured TransformerFactory to be
an instance of SAXTransformerFactory:
public static TransformerHandler createTransformerHandler() {
try {
synchronized(JAXBContextImpl.class) {
if(tf==null)
tf =
(SAXTransformerFactory)TransformerFactory.newInstance();
return tf.newTransformerHandler();
}
} catch (TransformerConfigurationException e) {
throw new Error(e); // impossible
}
}
Jason, what do we want to do? Implement SAXTransformerFactory too in
jboss-modules' __TransformerFactory ?

Also, getting rid of leading spaces when entering a command before parsing it, e.g.:
[/] connect
Unexpected command ' connect'. Type 'help' for the list of supported
commands.
[/]connect #works
[/] :add-system-property(name=foo,value=bar)
Unexpected command ' :add-system-property(name=foo,value=bar) '. Type
'help' for the list of supported commands.

We need to think about the security implications of this. Implementing
it basically means recording a history of commands in some store somewhere.
As an aside, for people playing with the CLI, you can actually bounce
the server, rebuild, do whatever, without closing the CLI process. If
the next time you type a command the server is available, it will all work.
No promises this will continue to be the case, but for now it's a
convenient way to keep command history -- just keep the process alive. ;)

Why wouldn't this continue to be the case ? it's all pretty stateless HTTP
operations ain't it ?

Why wouldn't this continue to be the case ? it's all pretty stateless HTTP
operations ain't it ?
It uses the native API. I don't see why it can't continue to be the
case, and I want it to be the case, but I didn't promise it because the
comment was just a quick FYI tangent on a thread.

A nice feature would be some history between cli sessions
agreed....
one thought though - is the intent to make the jboss-admin a full blown shell like
experience or is that
better served by other means ? i.e. integrate the cli into something like Seam Forge and
we benefit
from all the work in that shell...
...or using some clever bash/zsh magic to actually provide tab completion of AS7 commands
on a normal command line ?
