There are two new reconfiguration endpoints: smart and app-preferences. +* The smart interface allows you to send a JSON of keys that are either in app_preferences, app_config, or both. The broker figures out the overlaps, refreshes them in Consul, and makes the appropriate CDAP reconfiguration calls. The preferences API allows you to simply reset a CDAP app's application preferences (analagous to the call that was already in here for app_config). +* I broke the original app_config API to make all three reconfiguration APIs consistent. You give it "reconfiguration_type" and "config" for all three APIs. And hopefully for any future reconfiguration APIs, e.g., for hydrator pipelines. +* Hardcodes the cute short name "config_binding_service", now that DCAE is using short names. Obliterates usage of the env variable and removes passing it around all over the place. + +## [3.4.8] - May 16 2017 +* support JARs hosted at https webservers +* trim JAR URLs to prevent problems due to whitespace +* add a primitive get_version.sh script for the build team to use.. needs to be actually implemented instead of printing a fixed version right now.. + +## [3.4.7] - May 15 2017 +* EELF part 6... pretty much done at this point, some less-important logs could still be cleaned up maybe. +* All HTTP requests made from the broker to another HTTP API now include the XER. +* All functions in `src/workflows` are now EELF compliant, and produce detailed metrics logs. Workflows is the workhorse of all the major API calls so this tracks pretty much all requests the broker makes to to it's job. +* App Config reconfiguration is now a workflow + +## [3.4.6] - May 12 2017 +* All HTTP GETs issued by this broker now pass an/the XER... even if the downstream server is not expecting it #ExpectUs.. + +## [3.4.5] - May 10 2017 +* error EELF field implemented, three important Metrics EELF fields added +* src/workflows has no more lager (non EELF) statements... though it could use *more* EELF statements because part of it is not covered by logs.. + +## [3.4.4] - Apr 28 2017 +* four more EELF fields implemented, one ignored. + +## [3.4.3] - Apr 27 2017 +* Fixes audit records not being used at the end of API calls (they now are, and elapsed time is computed) +* Implements ISO8601 timestamps in all log records +* Implements a few more of the EELF fields, still more to go + +## [3.4.2] - Apr 26 2017 +* Towards Implementing the "ONAP logging requirements" aka "EELF": +* Logs are now written to /tmp/log/cdapbroker/... and are in three files: error.log, audit.log, metrics.log (logs are still also written to stdout) +* X-ECOMP-RequestID is now parsed and logged, and generated if missing, for all main broker APIs. It does not yet generate it's own for the call to the CBS. +* EELF logging functions added to a new source file `src/logging`. +* The field list formats and delimiters in each of those follow version 1.0 of the ONAP logging requirements. However, many required fields are left blank right now, this needs to be fixed. Parsing the fields should work though as each has the correct positional arguments and correct number of positions. +* Only functions in `src/resource_handler` are using the EELF logging functions right now, this needs to be fixed + +## [3.4.1] +* Move tests, update README + +## [3.4.0] +* Only healthcheck programs that are part of an intial program-flowlet PUT. The use case for this was a CDAP application that had flows that were purposely not wanting to be started by the component developer (whether that is valid is another question...) + The broker thought their application was in an unhealthy state because it was sourcing the programs to get the health of from CDAP itself, and not the intial PUT request. + This actually goes back to the way healthcheck used to work, but this now does it in a better way, because the application table is now used for multiple types of CDAP apps +* To accomplish the above, this creates a "supplementary" table for program-flowlet apps, that right now stores the programs that are in the intial PUT, but could be extended later with more properties. +* Paves the way for a "hydrator supplemental" table if that is ever needed +* Starts the painful process of adding function and type definitions so that the Erlang Dialyzer ("bolt on" static typing tool) is of some use; sick of huge positional tuples +* Fixes a bug where undeploy would not "plow through" if CDAP was totally unreachable (or gone) + +## [3.3.0] +* Broker now includes it's own API version in information endpoint + +## [3.2.1] +* Fix an error found in HTTP error reporting (a bad request type of error is now correctly caught) +* Fix errors in test cases found while testing a new version of CDAP. Tests are now more agnostic to json key ordering. + +## [3.2.0] +* Returns more information in the "infomation endpoint" ('/'). Specifically, now returns the CDAP GUI port and the CDAP cluster version. +This is mostly to aid component developers in testing that are hitting the broker via the DCAE CLI tool. +* Introduces the first unit test (eunit; the rest of the test suite is ran via common_test). + +## [3.1.0] +* Persistence. This is an important feature. This persists the MNesia database to disk so that you can stop and start the broker without losing state. NOTE: Catching Docker SIGTERM is not yet implemented. It turns out this is non-trivial to do in Erlang. So, in rare cases, if `docker stop` is called immediately after `delete`, the deletion may not persist to the database. +* Erlang 19.3 is supposed to handle SIGTERM at the BEAM level. That is not out yet as Docker (it was just announced a week ago.). +The proper way to shut down an Erlang node is to execute a command to the BEAM. +I don't know what Erlang developers did for 20 years, but to date the BEAM does not handle SIGTERM, so a wrapper script is needed if you want to kill the BEAM gracefully on a SIGTERM. +This was needed because this broker runs in Docker. With database persistence, the broker has a graceful stop function that ensures any transactions in cache (RAM) are persisted to disk before the shutdown. +I need this function called, so I need SIGTERM to be handled in a way that gracefully terminates the VM, which in turn gracefully shuts down my application, which in turn calls this function. Supposedly, this will be no longer necessary soon: http://www.erlang.org/news/110 + +## [3.0.0] +* Waterfall CDAP_CLUSTER_TO_MANAGE +* Handle CBS moving while broker is up +* For program-flowlet apps, return configuration when info requested +* make /application only return the appnames (API change) +* make testing more stable by not using order-dependent Expected JSONs +* Reconfiguring with an invalid request returns a 4xx instead of 5xx now (bugfix) +* Dead programs/flowlets now triggers a failing healthcheck (bugfix) +* Rename "reconfigure_app_config" to make way for reconfiguring preferences (API change) + +## [2.2.0] +* Implements healthchecking for Pipelines based on Terry S's healthCheck.py script + +## [2.1.0] +* Added a text file of some example commands that can be useful for demos and understanding this repo +* Fixed a bug in a workaround for https://issues.cask.co/browse/CDAP-7191?filter=-2 +* Added the ability to deploy Pipelines that contain custom JARs + +## [2.0.0] + +* Add support for primitive CDAP Pipelines.

To isolate CDAP developers from the complexity of the DCAE platform. The only thing CDAP developers should need to interface with are the CDAP APIs. They should not need to know about concepts like "service discovery" or "confiuration discovery". They should specify what external systems they should talk to in their configuration template and the rest should be hidden from them. </li> + +2. To minimize the onboarding process for CDAP developers. Their *only* deliverables should be a JAR (with built in metrics), and their configuration template. </li> + +3.

That is because a CDAP application can have multiple services behind it, so there is no way to register a CDAP application in Consul. + +The CDAP client library for collectors (or anything upstream of a CDAP app) will be required to do the following: + +1. do a consul service discovery GET on `appname` +2. Take that serviceaddress and port, and form `serviceaddress:port/application/appname` +3. Do a GET on that, which is the broker +4. Parse out `connectionurl` and `serviceendpoints`, which is input and output connection information for the CDAP app. See the swagger spec (in the swagger folder in this repo) for the schema of those. + +# Special charcters: hackaround +CDAP application names cannot have special characters in them. +When this broker talks southbound to CDAP, it maps `APPNAME` into `APPNAME_WITHOUT_SPECIAL_CHARACTERS`. So in CDAP you will see the latter. However, + when communicating with this broker API, you should still pass in `APPNAME`. The conversion is handled internally. + +# Logs +The broker conforms to ONAP/ECOMP logging requirements (aka EELF). The logs are written to `/tmp/log/cdapbroker/..`. If running in Docker, you'll want to mount this outside into a safe store. + +# Running and testing + +## Runtime Assumptions +In a real deployment setting, these assumptions are handled by the ONAP Docker plugin when this is launched. +When doing local testing, you must set up these assumptions yourself. + +1. `HOSTNAME` is set as an env variable in this runtime environment and is a Consul key that holds this broker's configuration. + +2. `CONSUL_HOST` is set as an env variable and is either an IP address or a resolvable name (Via real DNS whereever you are running this). It should not include the port, the broker currently hardcodes 8500. + +3. `CDAP_CLUSTER_TO_MANAGE` is an env variable, and cooresponds to a CDAP cluster registered in `CONSUL_HOST`. This is the CDAP cluster the broker will manage when it runs. The CDAP API port must be registered as well, that is, the broker does *not* hardcode "well known ports" and retrieves it from Consul. (Currently for CDAP 3 that port is 10000 and CDAP 4 it is 11011.) + +4. `CONFIG_BINDING_SERVICE` is set as an env variable, and cooresponds to the name that the CBS is registered in `CONSUL_HOST`. + +5. The user that runs this application needs write access to the directory '/var/mnesia'. This works in Docker, but on your local machine, this may not be owned by your local user.In this case, create the dictory and CHOWN it to your user. The broker writes it's database backup to that location. + +## The integration test suite +Bestides the unit tests, the broker comes with an integration suite that touches both Consul and CDAP (the ones pointed to via `CONSUL_HOST` and `CDAP_CLUSTER_TO_MANAGE`. It will actually deploy test apps, test configurations into Consul, and then delete them after the test suite is over. Please note that this is not a unit test, it touches the real systems the broker is connected to. It can be used to verify a signifigant portion of the DCAE, including CDAP, Consul, the broker, and the config binding service. + +The integration test suite requires several test artifacts to be loaded into a Nexus Raw Webserver. In the test suite, the root of this server is read from the env `NEXUS_RAW_ROOT`. Thus, in order to run the integration suite, in addition to the above runtime assumptions, this env must be set. +(TODO: Talk about the specific artifacts to be loaded in) + +## Docker + +### Build +Note: doing a Docker build *automatically* runs the unit tests.

Deleting the stream or it's data on the deletion of A1 would clobber A2. + +This leaves the question of who/what/when/where/why/how streams and datasets should be cleaned up from CDAP clusters in DCAE. +For now, this is an open question.
