Hi! I have a very fundamental problem with the current state of Tamaya. It grows and grows and grows and grows. But what for? What are the key benefits of all those classes?
I bet I don't see all the details, so please lets get a discussion started. As a simple start I just like to compare 2 known mechanisms: 1.) DeltaSpike The whole configuration system consists of 5 classes with in summary 800 lines of code (including license headers, tons of javadoc, etc). 2.) Tamaya 123 classes with 7500 lines of code So as you can see there is a HUGE difference in complexity. And to be honest I cannot see much justification yet. Even if you add the ProjectStage (3 classes, 500 LOC) and the full CDI integration (4 classes, 400 LOC) to DeltaSpikes configuration (features Tamaya don't yet have) then you are still way below Tamaya. But even with way more functionality. To be honest, I was reading through JavaDocs and sources and so far it was by far more WTFs than aha. Of course I most probably miss some features, so please help me to find those gaps and fill them. I'd like to suggest that we start a small game and collect use cases and how those might get solved with Tamaya and with DeltaSpike-config. In general we have to abstract 4 different aspects: 1.) the API/SPI 2.) the server provided functionality 3.) a user way to customize/extend the configuration functionality 4.) the user way to read the configured values I'll give you an example of a use case: A company uses REST endpoints and need to talk to those. So we need to configure a few things: 1.) the endpoint URL 2.) the username which should be used to connect (e.g. over https, BASIC auth, whatever) 3.) the passphrase which should be used to connect. The security credentials (passphrase) should not get stored in plaintext but encrypted using PKI. It should of course also not get logged out in clear text but shall get masked if logging out the configured values is enabled. In DeltaSpike I'd just register a ConfigFilter to do the password decoding on the fly. So this is pretty much straight forward. How is this handled in Tamaya? Now it's your turn: give me some use case where you think the current tamaya source is strong. And then we gonna discuss it. If something is not needed or easily solvable otherwise then we gonna drop those parts which are superfluous. NOW is the time to do such things! If all features and sources turn out to be there for a good reason than I'm happy to keep them. If there is no VERY GOOD reason, then it will get cut out. Not sure about the others around here, but I personally am a really big fan of KISS (Keep It Simple and Stupid) when it comes to such fundamental (in the sense of important fundament and foundation) pieces. txs and LieGrue, strub
