Consider migration to dl-repository-shared layer

[izaera]

Hi @topolik:

I didn't know you had created this connector. Looks good and it's a great idea.

I was wondering if you could be interested in looking at dl-repository-shared layer, which is a JAR file I wrote to make implementation of connectors much easier and maintainablec.

It's in here: https://github.com/liferay/liferay-plugins/tree/master/shared/dl-repository-shared
You can see how it is used in Documentum and Sharepoint connectors in liferay-plugins-ee.

If some day you consider to migrate to this new layer don't hesitate to ask me for any advice.

Cheers,
Ivan

HI @izaera

Looks promising, thanks!

If you finally decide to apply it, ask me and I will give you a brief introduction on how it is supposed to work. Basically what I did is separating the portal stuff from the external repository stuff, so that you only have to deal with the external repository and not with Liferay portal.

For example, when using dl-repository-shared you don't need to work with Liferay ids, only with the ones from your external repo. You don't even need to manipulate the RepositoryEntry table because it is not referenced anywhere in the interfaces you need to implement. You just provide an implementation for the file, folder and version object, and another one with the operations the repository support and that's all.

This looks very very good. I had to implement that myself, all the mapping.

Btw. does it support DL permissions? Once the IDs are on the framework side the implementation cannot work with resource permissions.

I'm not sure of what you mean. There's a place where you have to map
"Liferay permissions" to "your repo permissions". See this file:

https://github.com/liferay/liferay-plugins/blob/master/shared/dl-repository-shared/src/com/liferay/repository/external/ExtRepositoryObject.java

method containsPermission() receives an ExtRepositoryPermission, which
is an enum defined at the end of that class. Those are based on
Liferay's ones, but it's only a subset of what is needed. For example I
removed CREATE_SHORTCUT because there's no support for shortcuts in
external repos.

I mean - portal admin creates custom role that is able to create DL
folders. Does it check that permission and make sure it cannot reach my
code when user doesn't have the permission?

No idea :-(. I would have to check it in the code. I suppose the answer
is yes, but I cannot give you the answer off the top of my head.
