Description of problem:
If try to use rhc commands with newer API version than server, all other commands can work well exept using rhc tail. Please refer to the error as below:
# rhc tail -a app9

Version-Release number of selected component (if applicable):
devenv_state_197
git clone latest rhc client and rake package on devenv_2341 (Which already contains changes for US2853 )


How reproducible:
always

Steps to Reproduce:
1. Launch an old stage instance, like stage 197 which supported API version is 1.0
2. Using latest rhc client with supported API version is newer, this client supports 1.0, 1.1, 1.2 
3. Try to use rhc tail
  
Actual results:
Error is shown.

Expected results:
"rhc tail" function can work well with following warning message shown.

WARNING: API version mismatch. This client supports 1.0, 1.1, 1.2
but server at ec2-23-20-167-201.compute-1.amazonaws.com supports 1.0

Additional info:

Comment 1 Hiro Asari 2012-10-19 18:54:40 UTC
The line in question is: https://github.com/openshift/rhc/blob/rhc-0.99.7-1/lib/rhc/rest/application.rb#L128

The message suggests that "cartridges" is somehow empty. The API version 1.0 should allow retrieval of cartridges, but we are getting an empty list. Since this server is only running a broker that supports API version 1.0, it is conceivable that it is a bug lies with the broker, rather than with the client. I tried connecting to the server mentioned, but was unable to.

What does:

    curl -H "Accept: application/json;version=1.0" https://openshift.redhat.com/broker/rest/api

return?

Looking at the returned data, look at the part that says: "LIST_CARTRIDGES". The hash value for that key has a pair that looks like:

"href":"https://openshift.redhat.com/broker/rest/cartridges"

Run:

  curl -H "Accept: application/json;version=1.0" https://openshift.redhat.com/broker/rest/cartridges # use the URL given above

And see if it returns anything. If it's blank, the broker is not holding up its end of the API contract, so there is not much the client can do.

Comment 2 joycezhang 2012-10-22 05:22:23 UTC
It's not blank when using rest api to get cartridges as below:

So assign it back. Thanks.

Comment 3 Hiro Asari 2012-10-22 23:42:22 UTC
Please advise what version of AMI for the OpenShift server I should use to test this.

And also, please verify what the server reports in JSON.

Thank you.

Comment 4 Hiro Asari 2012-10-23 00:01:43 UTC
Using the latest AMI (devenv_2362) and rev e090ab3 (https://github.com/openshift/rhc/commit/e090ab39f0b289438e76ff82b7566aab866e9a19), I get:

Also, can you check with 0.99.8-1 or 0.99.9-1 and pass '-d' flag?

Comment 5 joycezhang 2012-10-23 02:32:26 UTC
This bug is occurred when the rhc client API version (1.0, 1.1, 1.2) is newer than the server API version (1.0). So we lanched devenv_stage_197 for this testing as the description. It works well with other rhc commands in this case, reasonable warning message are shown and functions are ok except using rhc tail.
Here are the steps for your reference:

Build:
devenv_stage_197 (Supported API 1.0)
Tested with following clients supported API 1.0, 1.1, 1.2
git clone latest rhc client and rake package on devenv_2341 (Which already contains changes for US2853 )
rhc-0.99.10
rhc-0.99.9

Steps:
1. Create an app.
2. Run rhc tail:
# rhc tail php5 -d

Comment 6 Hiro Asari 2012-10-23 05:37:58 UTC
Thank you for the information.

Could you confirm that you had not added any cartridge after creating the app under the testing scenario?

If you have not, does the error persist if you add any cartridge?

If you have, does the same error message appear if the server's API versions include newer ones?

Comment 7 joycezhang 2012-10-23 06:54:57 UTC
Thanks for your quick feedback. Yes, I didn't add any cartridges to the app. 
I just tried to add mysql to the app, it's different as below:

Chris, can you take a look?

Thank you.

Comment 9 chris alfonso 2012-10-23 12:33:26 UTC
When an application is created, there should be a standalone cartridge created, correct?  The list of cartridges is empty with the 1.0 server API.  The new api for tailing a log requires that we use the cartridge name in the path for the default file glob.  Perhaps in the case of the 1.0 server api, we should fall back to using the application name as the root directory for the file glob.

Even if we did have the standalone cartridge name with the 1.0 server API, if we tried to use the standalone cartridge name as the root directory for the file glob, it probably wouldn't work since it was as recent change to the broker that switched from the application name to the standalone cartridge name.

Hiro, do you concur?

Comment 10 Hiro Asari 2012-10-23 15:45:27 UTC
Chris,

If the 'tail' command requires API > 1.0 and there is nothing reasonable to show under such conditions, then we need to bail out. But if there is anything at all to show, I'd rather see that instead.

Comment 11 chris alfonso 2012-10-23 18:58:38 UTC
After discussing this with clayton, we will not be supporting an api previous to 1.2.  Furthermore, we will not have any servers running an api < 1.2.  We should however build into the rest client a method for each command to call if they required an api version, for use after the 1.2 api release.

Comment 12 Hiro Asari 2012-10-23 20:40:33 UTC
Given the above discussion, then, I am going to mark this bug as "WONTFIX", assuming that we will not encounter any OpenShift server that does not support 1.2 in the wild.

Comment 13 Clayton Coleman 2012-10-26 17:43:40 UTC
Hiro, this is the item we discussed earlier this sprint that you were going to own - adding support to the rest client to require a specific app version in a command by command basis (rest_client(:at_least => 1.2))

Comment 14 Hiro Asari 2012-10-29 20:55:17 UTC

Comment 15 Wei Sun 2012-12-21 10:50:59 UTC
Test on devenv_2621,rhc client is rhc 1.3.2

If client API version is changed to server supported lowest version 1.0, error "NilClass (NoMethodError)" is shown when using rhc tail.

Comment 16 Fabiano Franz 2013-07-22 19:53:20 UTC
Not an issue anymore on OSE since we only officially support 1.2.
