New Tables and data were created by modbus client. The tables are listed correctly under the Database detail screen (My Databus -> Databases), but the Dashboard view still shows a series of [presumably fictitious] Tables and charts.

Requesting high priority because it makes the system difficult to demonstrate.
[Priority: 8 high]

When you click on the name of a table, you see a list of the columns in the table and a column indicating whether those columns are indexed. It would be helpful to also see the type for each column (integer, float, string) so that you know what type of data to expect when you download it. Thanks,

I have an Android app that sends data files every minute to databus. Every once in a while I get back an http error 400 (bad request). However when I try to send this file again either through the same code or via curl, it uploads fine.

When I looked at the databus log file for the time period of the error I see

WARN: There was a problem parsing the JSON request.
org.codehaus.jackson.JsonParseException: Unexpected end-of-input: expected close marker for ARRAY (from [Source: java.io.StringReader@898e150; line: 1, column: 1])
at [Source: java.io.StringReader@898e150; line: 1, column: 24607]
at org.codehaus.jackson.JsonParser._constructError(JsonParser.java:1433) ~[jackson-core-asl-1.9.8.jar:1.9.8]

But the file is valid json (I ran it through jsonlint and it also sends correctly the 2nd time). Given that databus is reporting the error on the first character, and this is a 26K file, my guess is that the problem is really some kind of temporary network connection issue and it is not actually getting the complete file, or not getting any file in the http POST, but the databus code is not catching that at a higher level and is sending bad or empty data to the parser, which generates the 400 error.

The problem is that then I can't detect the difference between a legitimately bad file and a temporary connection error, in which case I want to retry sending the file.

When using the internal user list for authentication, log in as an administrative user and create a user. Then delete the user, and create a new user with the same name (for a password reset for example). Now the user list shows two entries for that username. Repeat the delete and create, and now there are three entries, etc. The user can log in with the most recent password, but if the user was listed as an administrator, they will not have administrator privileges.

The pages for csv upload through the web interface do not have any navigation buttons. Request: add the standard header & footer, or some other form of navigation elements, to the pages related to csv uploatd. In particular, the "success" page has no navigation elements at all.
Priority medium because the ratio of value for demo ("polish") to effort is high.
[Priority 5 medium]

In the web interface, when you click a button for Add User, Add Robot, or Add Group, the resulting screen for entering the information for the User/Robot/Group is always labeled "Add User".

In the prototype "System Summary" view, my database is listed twice (DataBase1).
NB: I created this database using a prior build.
Created a new Database with current build, and it is also listed twice.

I'd like to run DataBus on a publicly-accessible server and I can't use our organizational Active Directory server for authentication in this case (IT dept. says no). The number of people who will need access to the server is very small and easily managed. So, feature request: another way to manage user authentication and log in to DataBus. Maybe using the server's user list with PAM or similar? Or, if I understand correctly, DB is keeping a small database of users who have logged in; can there be an interface to modify this user database?

The web interface shows "version 1.0 beta" in a relatively large and visible location. That value hasn't been changing, and its not (IMHO) a good use of the space. Request: display a more granular version number (build number?) in a sub-menu or About link, so that the admin can verify that the latest updates were applied correctly.

When a new DataBus installation is created, it is populated with lots of "demo" data, like agg1Db, groupofusersandgroups, etc. This is useful for Demo mode, but not for Production. Note this demo data is created in Production mode for installations that are not using Active Directory.

I am trying to register my table columns via java code, but I always get an internal server error 500 result with error message "Oops, an error occured". I am logging the json string I am sending to the registerV1 api and if I copy that string from the log and paste it into a file and send using curl, it works fine. If I then try again with my code, I get the error that the table exists, so I know that the register module is getting to the point of parsing my json. I am sending the json as a stream entity. This code works fine when I send data using the postdataV1 api.

Code looks like so:
logger.info("post data to: " + registerUrl);
HttpPost httpPost = new HttpPost(registerUrl);
httpPost.setHeader("Content-Type", "application/json");
DefaultHttpClient httpClient = new DefaultHttpClient();
httpClient.getCredentialsProvider().setCredentials( new AuthScope(mServer, 9000),
new UsernamePasswordCredentials("robot-robotTest2", "45580RCV5S.ALPHA1.1PT80JZFNKHUG"));

String androidID = Settings.Secure.getString(mContext.getContentResolver(), Settings.Secure.ANDROID_ID);
String tableJson = "{"datasetType":"RELATIONAL_TABLE", "modelName":"ANDROID4_" + androidID + "", "schema":"sensorTest", " + tableCols + "}";
try {
httpPost.setEntity(new StringEntity(tableJson));
} catch (UnsupportedEncodingException e1) {
logger.severe("encoding error in json string");
e1.printStackTrace();
return;
}

try {
// do the post
logger.info("sending table data: " + tableJson);
HttpResponse response = httpClient.execute(httpPost);
StatusLine status = response.getStatusLine();
logger.info("http post response: " + status.getStatusCode() + " - " + status.getReasonPhrase());

It appears that the "initial turn-on" for the Databus code that external users can download has a sort of "demo mode" built-in, with some fake users, and fake data. Is this correct?

This seems like it is asking for trouble- you have to have a build system which supports production and test builds, or modes or something, and the code contains a lot of stuff that is not related to the core functionality.

Instead, is it possible instead to a "demo script" which would provision a Database, make a few Tables, and load them with fake data? A new user could run this script after installing Databus for the first time. The script could even have "pause and press any key" features, where the user is invited to look at the web interface and see the new database listed, now click on Tables and see the tables, now click on Charts and see the data, etc.

This would make for cleaner code, illustrate the API capabilities, and serve as a programming example.

Hi,

Thanks for creating a great product. We're writing a AngularJS frontend to interact with Databus, but it seems like the API does not support CORS or JSONP to allow HTML5 cross site applications to work.

We really only want to do GET requests to get time series out for plotting and displaying.

It seems like something you can add relatively easily. I found these links:

The application secret key is the same for all installations. It would be better if a new key was generated during the build process, so that different customers will not have the same key. A simple (not super high crypto validated) random generator would be fine here.

Request for the ability to delete Databases and Tables. Especially necessary while Table names must be unique in the system. Prefer web interface because it is an administrative thing, not likely to be automated, but API interface would be fine in the short term.

Setting the log level in the configuration file with

application.log

does not seem to affect the output from Play. I was assuming I could use the log4j levels TRACE, DEBUG, INFO, WARN, ERROR and FATAL ?

When uploading multiple entries, you have to specify the table for every entry. For example:

{"_dataset":[
            {"_tableName":"timeSeriesExample","time":1360006292000,"value":162.6911},
            {"_tableName":"timeSeriesExample","time":1360006293000,"value":163.6911}
    ]
}

The name of the table is redundant. The message would be more efficient if the table could be specified once per upload message. Something like:

{"_tableName":"timeSeriesExample","_dataset":[
            {"time":1360006292000,"value":162.6911},
            {"time":1360006293000,"value":163.6911}
    ]
}

Request: Ability to add/modify/delete Tables in the Web Interface
[Priority: 3 low]

The web interface page listing Tables (My Databus -> Tables) does not show any tables.
