Re: OBR and automatic bundle update

2012-04-05 Thread Matias SM

Hi Richard,
I've given this issue some more thought and I realized that my starting 
point stands (a copy of the original mail is at the end of this one).

If I try to execute these steps:

g! deploy -s DA
g! deploy -s A@1.0.0.1
g! refresh
g! deploy -s DexA

The deployment of DexA fails. If I understood correctly our discussion 
about bundle's location string (first mail quote after this one)and OBR 
, it shouldn't fail since OBR should try to deploy A@1.0.0.2 as an 
update of A@1.0.0.1 (or, at least, to install it using a different 
location string).


The execution of the presented test case throws the following exception 
(note I changed the output's bundle names and versions to accommodate to 
the examples ones):


Target resource(s):

As I suggest you need to have two different paths.

However, this isn't an issue for OBR since it uses an arbitrary location 
string, so it is always unique when it does an install, which you can't easily 
do from the shell, like I said before.

Am I missing something? Do you prefer I create a JIRA issue with

Ok, thank you very much for your comments Richard.
I will keep them in mind and do further experimentation.

The location string is a deployer assigned persistent identifier, so it cannot

location string for simple installs, but the two are unrelated in reality.

Ok, I see. Shouldn't the location string be replaced (with the updated

confusing.

Thank you very much for the clarification, I will do some more

As I suggest you need to have two different paths.

However, this isn't an issue for OBR since it uses an arbitrary

location string, so it is always unique when it does an install, which
you can't easily do from the shell, like I said before.

Hi everybody,
I'm using OBR to help me resolve bundle deployment. Everything works

Here is my test scenario:
I have the following bundles in an OBR repository:
* SymbolicName: A | Bundle-Version: 1.0.0.1 | exports: (package: p.a 
version: 1)
* SymbolicName: A | Bundle-Version: 1.0.0.2| exports: (package: p.a

* SymbolicName: DexA | Bundle-Version: 1| depends: (package: p.a 
version: [1 , 2) ) and (bundle: A version: [1.0.0.2, 1.0.0.2] )


Then my test runs as follows:
g! deploy -s DA
== this also deploys A version 1.0.0.2 (I guess because it is the 
newer bundle that exports pa version 1)


g! deploy -s A@1.0.0.1
== this __updates__ the previously deployed A (version 1.0.0.2)

First issue, if I run:
g!deploy -s A@1.0.0.2

(since there is an updated version of it already resolved). I know 
this is the expected behavior, but I would like to be able to deploy 
A@1.0.0.2


It seems like OBR should probably be performing a refresh after it does 
an update, so there isn't an older version hanging around.




Second (and worse) issue, if I now run:
g!refresh
== so A@1.0.0.2 is completely uninstalled from the framework
And then:
g!deploy -s DexA
== this deployment __fails__ because A@1.0.0.2 can't be 
reinstalled in the framework!!


Not sure why that would be. Are you seeing some sort of error?

Still not clear to me what the actual issue is or the solution, but at a 
minimum OBR should probably refresh after update.

No. OBR doesn't keep some set of desired deployed bundles or anything 
like that...it isn't that sophisticated. It simply tries to deploy 
bundles given the current context of the framework. So, the fact that 
you told OBR to deploy foo in some previous request has no bearing on 
subsequent requests other than the fact that it impacts the set of 
installed bundles from which it starts to perform its operation...but 
that is no different than if you installed a given bundle manually and 
didn't use OBR at all.

Hi everybody,
I'm using OBR to help me resolve bundle deployment. Everything 
works great and as expected but I'm facing a situation I don't 
know how to solve.


---
Here is my test scenario:
I have the following bundles in an OBR repository:
* SymbolicName: A | Bundle-Version: 1.0.0.1 | exports: (package: 
p.a version: 1)
* SymbolicName: A | Bundle-Version: 1.0.0.2| exports: (package: 
p.a version: 1)
* SymbolicName: DA | Bundle-Version: 1| depends: (package: p.a 
version: [1 , 2) )
* SymbolicName: DexA | Bundle-Version: 1| depends: (package: 
p.a version: [1 , 2) ) and (bundle: A version: [1.0.0.2, 
1.0.0.2] )


Then my test runs as follows:
g! deploy -s DA
== this also deploys A version 1.0.0.2 (I guess because it 
is the newer bundle that exports pa version 1)


g! deploy -s A@1.0.0.1
== this __updates__ the previously deployed A (version 1.0.0.2)

First issue, if I run:
g!deploy -s A@1.0.0.2
== then OBR executes successfully but A@1.0.0.2 is not 
installed (since there is an updated version of it already 
resolved). I know this is the expected behavior, but I would like 
to be able to deploy A@1.0.0.2


It seems like OBR should probably be performing a refresh after it 
does an update, so there isn't an older version hanging around.




Second (and worse) issue, if I now run:
g!refresh
== so A@1.0.0.2 is completely uninstalled from the framework
And then:
g!deploy -s DexA
== this deployment __fails__ because A@1.0.0.2 can't be 
reinstalled in the framework!!


Not sure why that would be. Are you seeing some sort of error?



I think that the problem here is that to be able to update the 
dependency again to A@1.0.0.2, OBR should withhold A@1.0.0.1 (that 
was deployed in step 2). I don't think this should be a valid thing 
to do.


Still seems like it should be possible for OBR to deploy DexA by 
updating 1.0.0.1 to 1.0.0.2.


Wouldn't that break the request that bundle A@1.0.0.1 is deployed 
(step 2 in test)?


No. OBR doesn't keep some set of desired deployed bundles or 
anything like that...it isn't that sophisticated. It simply tries to 
deploy bundles given the current context of the framework. So, the 
fact that you told OBR to deploy foo in some previous request has no 
bearing on subsequent requests other than the fact that it impacts the 
set of installed bundles from which it starts to perform its 
operation...but that is no different than if you installed a given 
bundle manually and didn't use OBR at all.


Ok, now I understand your point. Though I can see that this behavior may 
lead to some issues if bundle A@1.0.0.1 has some kind of functionality 
other than defining classes to export.

In the OBR project web page [1] can be read:
OBR's deployment algorithm appears simple at first glance, but 
it is actually somewhat complex due to the nature of deploying 
independently developed bundles. For example, in an ideal world, 
if an update for a bundle is made available, then updates for all 
of the bundles satisfying its dependencies are also made 
available. Unfortunately, this may not be the case, thus the 
deployment algorithm might have to install new bundles during an 
update to satisfy either new dependencies or updated dependencies 
that can no longer be satisfied by existing local bundles. In 
response to this type of scenario, ___the OBR deployment 
algorithm tries to favor updating existing bundles, if possible, 
as opposed to installing new bundles to satisfy dependencies.


I don't fully understand this explanation but I get that the 
described behavior is as intended.


Not sure which part you don't understand.


What I don't understand is how the need to favor updating existing 
bundles is concluded from the problem stated in the previous 
sentences. It is not clear to me the relation between the need to 
install new bundles during an update and the algorithm that 
tries to favor updating existing bundles instead of installing new 
ones.


Ok, I see your point now. No, the one doesn't necessarily follow the 
other. The reason to favor updating existing bundles is the reason I 
gave below.








My questions are:
1- Is there a way to force the installation of different bundle 
versions (instead of the update of older ones) when deploying 
through OBR?


No, I don't think so.

2- What kind of issues may this behavior (installation of 
different versions) rise? (this is not considering the problem 
of having a lot of bundles installed)


Lots of providers is generally a bad thing since it creates many 
partitions in the overall class spaces of the bundles, meaning 
that

Yes, you are using the same path when you try to install the first bundle the 
second time and this will not work since that path is used as a unique key, 
which is why it returns the same bundle id as printed in your session since it 
did not install anything the second time.

As I suggest you need to have two different paths.

However, this isn't an issue for OBR since it uses an arbitrary location 
string, so it is always unique when it does an install, which you can't easily 
do from the shell, like I said before.

Ok, I see. Shouldn't the location string be replaced (with the updated 
version location) when the bundle is updated? It seems a little confusing.


Thank you very much for the clarification, I will do some more 
experimentation keeping in mind what we discussed.

Re: OBR and automatic bundle update

2012-04-02 Thread Richard S. Hall
The location string is a deployer assigned persistent identifier, so it cannot 
change. Your confusion arises because frameworks use the URL as the default 
location string for simple installs, but the two are unrelated in reality.
