and I am kind of dissapointed there is not a marketing department to share them with the world

Can ye help me install this great piece of software please? Really keen to test it out

java -version gives

@groldan

ok, I see. And geogig --version?

Shane Carey

@careyshan_gitlab

geogig --version gives

@groldan

well, if you're kind to wait a little bit I'll cut an alpha release out of master right away

should be much better than the one you have even if it worked, which might be 1.2, way too old

Shane Carey

@careyshan_gitlab

Ok cool, that would be great

Thanks

Gabriel Roldan

@groldan

ok deal

Jody Garnett

@jodygarnett

fun

what is the problem above BTW?

Shane Carey

@careyshan_gitlab

I've no idea, @groldan might know. I hope I can get it working. Looks awesome!

Shane Carey

@careyshan_gitlab

Hey @groldan ,Just wondering when do you think you might get to this? Just curious so that I can try it out. Thanks very much

Gabriel Roldan

@groldan

cought me in the middle of cutting a geotools/geowebcache/geoserver release also, and that might take a couple more hours. I think I can compromise to have it by tomorrow though

Shane Carey

@careyshan_gitlab

Ok cool -thanks. You might drop me a message when its cooked :) Thanks

Gabriel Roldan

@groldan

@careyshan_gitlab I've just released 1.4.0-beta.1, you can download the binaries from this link: https://github.com/locationtech/geogig/releases/download/v1.4.0-beta.1/geogig-1.4.0-beta.1.zip

The "unable to provision" error is most definitely due to using Java 11 instead of Java 8.

I don't have time right now to investigate what to fix for it to run on java 11, but will definitely need to do so asap

Shane Carey

@careyshan_gitlab

Hey @groldan - This worked like a charm and its pure magic! I love it! Well done to all involved :)

Could anyone help me configure Geogig 1.2 with the Geoserver? At the moment I have Geoserver 2.16.1 installed. Im following the instructions to configure the Geoserver plugin using the "geogig-1.2.1-geoserver-2.12-plugin.zip" release but whenever I reach the point of checking out a Geoserver branch (say 2.16.x), I am told that "Not a git repository (or any of the parent directories): .git". Any guidance on how to connect Geogig and Geoserver

Jody Garnett

@jodygarnett

GeoGig was rewritten so the servlet could be independent of GeoServer. I am not sure if their is a maintained geotools datastore for use in GeoServer right now.

The instructions here (http://geogig.org/docs/interaction/geoserver_ui.html) for example may be out of date.

I can see something here https://github.com/locationtech/geogig/tree/master/src/geotools/datastore

AStarzec

@AStarzec

@jodygarnett if GeoGig is now independent of GeoServer, do you have any recommendations/suggestions on where remote repositories can be hosted for multiple users to push and pull commits to/from?

Jody Garnett

@jodygarnett

The project includes a server I think

Matthias Kuhn

@m-kuhn

Wow, I noticed that there is new release coming up, lovely to see!

Is there information around about which operating systems are supported?
I especially wonder if someone is running GeoGig on iOS

Jody Garnett

@jodygarnett

It is a Java app, so not available on iOS

The approach could be used, and an iOS app could be written to use the web API

Much like how the QGIS plugin is done

Matthias Kuhn

@m-kuhn

Is there a description of the web API?
Is it possible to calculate diffs / individual commits client side to reduce data transfer volume?

Luigi Pirelli

@luipir

@m-kuhn probably ls of api are changed... but an "old" base can be found in https://github.com/planetfederal/qgis-geogig-plugin

Matthias Kuhn

@m-kuhn

Thanks @luipir and @jodygarnett
Do you have any feedback on the specific question (it would be easier than trying to read through the plugin code ;) )

Matthias Kuhn

@m-kuhn

@jodygarnett @groldan are there any plans or desire to add support for this kind of operation on mobile platforms?
Or is it not wanted / not feasible / missing ressources?

Jody Garnett

@jodygarnett

It was part of the plan, but boundless has packed it in.

Idea is to make client libraries that can build up Diffs to send to that servlet

I am sure Gab still has the design in his head. Not sure I’d code was cut.

Matthias Kuhn

@m-kuhn

So that'd mean writing core parts in C++ and cross compile or writing and maintaining these pieces in parallel in several languages ?

Jody Garnett

@jodygarnett

I think the diffs sent to the servlet are pretty simple problem to mange by comparison to all the version control stuff.

So I would view this as writing a client and not writing a core part.

Could have a look at the QGIS plugin which is just such a client to get an idea of the work involved.

It would be GPL which prevents direct reuse of the code for iOS, but a working example is worth something.

(Note I am not Gab or Blasby so my knowledge is second hand beyond some IP help)

Matthias Kuhn

@m-kuhn

It will also need to be able to apply the diffs to merge back changes on a possibly modified local base... I guess there would be one or the other versioning challenge to master anyway.

RE license: If it's rewritten as a client app it does not necessarily need to be GPL and iOS does not prevent GPL (it's the appstore that is ... well questionable... to put it mildly)

Jody Garnett

@jodygarnett

It may be worth scheduling a chat or something with gab / blasby if you have something in mind.
