	== Prepaing release of Marauroa 4.0 ==		== Prepaing release of Marauroa 4.0 ==

		⚫	A couple of years ago we started to experiment with web clients. We did several attempts using different technologies. To cut a long story short: Only recent browser developments enabled us to build a working webclient. All this time, most of Marauroa's development was done on a branch named perception_json, with only minor changes being backported to master.
	* After years of development, perception_json was merged into master.

⚫	* Release bockers are tagged with [https://sourceforge.net/p/arianne/developers/search/?q=labels:%22MARAUROA_03_99%22 MARAUROA_03_99]
			Without a real working client, I was afraid that the Marauroa interface were not tested against real requirement. But the last attempt to write a Stendhal webclient is very promissing (although there is still a lot of work required). So perception_json branch was merged into master recently.

		⚫	We should do a Marauroa release in the near future: Release bockers are tagged with [https://sourceforge.net/p/arianne/developers/search/?q=labels:%22MARAUROA_03_99%22 MARAUROA_03_99]
	20:39hendrik2. Marauroa 4.0

⚫	~~20:40hendrikA~~ couple of years ago we started to experiment with web clients. We did several attempts using different technologies. To cut a long story short: Only recent browser developments enabled us to build a working webclient.
		⚫	* Most important is updating documentation and examples.
	20:40hendrikAll this time, most of Marauroa's development was done on a branch named perception_json, with only minor changes being backported to master.
			* Stendhal should be able load the maps from transfer-content so that that part of the json protocol gets tested as well. Currently Stendhal uses Marauroa's binary serialization internally to provide content. So either the JavaScript needs to understand it, or the server needs to provide alternative content
	20:41travis-ciarianne/stendhal#103 (master - 98affef : Hendrik Brummermann): The build passed.
			* Changing structure of gameEvents table to use references instead of source string. Postponed after 4.0
	20:41travis-ciChange view : https://github.com/arianne/stendhal/compare/c4c927c49d7c...98affef72de0
			* Re-adding support for Marven which was deleted because mvn test is broken and Travis insists on using Maven instead of Ant. We should aim to restore it before release. But this is not a release blocker.
	20:41travis-ciBuild details : https://travis-ci.org/arianne/stendhal/builds/100661020
	20:41*hendrik glares at travis: That was not suppose to happen. But it has to wait until later.
	20:42kiheruwhy not? the config says "on_success: always"
	20:42hendrikI changed that with the recent commit to "change2.
	20:43kiheruprobably not. you changed stendhal/.classpath, not stendhal/.travis.yml
	20:43hendrikargh.
	20:44hendrikWithout a real working client, I was afraid that the Marauroa interface were not tested against real requirement.
	20:44hendrikBut the last attempt to write a Stendhal webclient is very promissing (although there is still a lot of work required).
	20:44hendrikSo I merged the perception_json branch into master, updated CHANGES.txt.
	20:45hendrikI think we should do a Marauroa release in the near future.
	20:45hendrikhttps://sourceforge.net/p/arianne/developers/search/?q=labels:%22MARAUROA_03_99%22
	20:46hendrikThat is a list of tickets concerning aspects that we should think about before releasing.
⚫	~~20:46hendrikMost~~ important is updating documentation and examples.
	20:46kiheruprobably should try to make the webclient load the maps from transfercontent so that that part of the json protocol gets tested as well
	20:48*hendrik nods: That is one major remaining problem: Stendhal makes use of Marauroas transfer protocol.
	20:48hendrikThat is, at least some layers such as tileset and map_data, contain serialized Marauroa objects.
	20:49kiheruusing the binary serialization?
	20:50hendrikYes :-/
	20:51hendrik"typed arrays javascript" is something to look into.
	20:51kiheruouch
	20:51hendrikI am not sure if that will help.
	20:52hendrikWe could blame it on Stendhal. But perhaps there is a way to solve the issue in Marauroa. I am not sure, yet.
	20:52kiheruat which point is the serialization format decided? I mean most of the traffic gets serialized to json, but apparently some using the binary
	20:53kiheru(I should remember what map_data does, but apparently I don't)
	20:53hendrikIt is decided when a Message is sent to the client. The subclasses of Message have both methods.
	20:53hendrikSo a json message with the transfer data is sent to the client. This part works.
	20:54hendrikBut the data that Stendhal tells Marauroa to transfer, is already binary serialized.
	20:55hendrikpublic void transferContent(RPObject target, List<TransferContent> content) {
	20:55hendrikin RPServerManager.
	20:56hendrikI still need to look at the Stendhal side.
	20:58hendrikLet's postpone that until after the meeting.
	20:59hendrikAnother open issue is, that I deleted the Maven pom.xml file.
	20:59hendrikI was unable to get travis pick up "ant test" with the pom.xml file existing. And "maven test" is not working.
	21:00hendrikWhile I don't think that Maven support is a blocker, it would be nice to restore it.
	21:00hendrikAnd then there is the breaking change of gameEvents.source (String) to gameEvents.character_id (int).
	21:00markusI could look into that. :)
	21:01hendrikthank you.
	21:01hendrikWhile I prefer to use references, I am not sure about changing the table structure before 4.0
	21:02markusIf we want to release soon we should consider delaying that one. Although I think it is a good idea.
	21:02hendrikHaving a new major version number is kind of a justification for such changes.
	21:02hendrikBut, ... what Markus just said.
	21:04hendrikDatabasewise, I would automatically rename the existing gameEvents table and create a new one with the new structure, setting the id to the last id from the old table.
	21:05hendrikAs updating the data will likely take a couple of days.
	21:05postmanarianne: balaur * developers #274 [Marauroa] Maven for Marauroa http://sf.net/p/arianne/developers/274
	21:06hendrikBut there are cases in which source is not refering to player. For example on kill events, source refers to the killer, which may be a creature.
	21:09hendrikbalaur raised some other important points about Maven in the linked ticket.
	21:09markusyes, saw that :)
	21:10hendrikAnything else we need to keep in mind for the Marauroa release?
	21:10markusmaking character_id nullable is no option?
	21:11hendrikAnd have that in addition to source?
	21:13hendrikThis may need some more thinking. I tend to exclude it from 4.0.
	21:13hendrikOpinions about including or excluding?
	21:14markusI'd go for excluding.
	21:14markusMight be an option to make that an addional column.
	21:16hendrikOkay, so let's consider that change not a release blocker.
