long datastore names

[Fabrice Bacchella]

I committed a patch that should allow longer than 20 characters for datasource name. I raised the limit to 65535 characters.

https://github.com/rrd4j/rrd4j/commit/68c3569ac2dd252485d5a05db03f3701c7ddae9f

I needed to encode a offset in the dsname, using the private use area from unicode (https://en.wikipedia.org/wiki/Private_Use_Areas). So if a long name is used and the rrd read by an old library, the name returned will be the long name reduced to about 17 or 18 characters, depending of the length of the file, with a  few undisplayable characters appended. But if this area is already used for some custom usage, some strange results will happens.

Perfect!!!
This has been a weak spot of the lib.

Thank you for your super work!!!
In which version is the patch entered?

[Fabrice Bacchella]

It will be in the next 3.2.

But if you want to play with it, you can have a look at:

Hi Fabrice,

we are very interested in having long data source names. Is there already a date scheduled for the 3.2 release?
Having a release version would greatly simplify consuming this feature.

Kind regards,

Not yet sorry, but I can feel a lot of pressure about it, other features are waiting too.

I will try to schedule it for october.
