Overpass API developpement

[Roland Olbricht <>]

Dear all,

to get towards merging outstanding pull requests, I have pushed the 
current state of affairs as a new version:
http://dev.overpass-api.de/releases/osm-3s_v0.7.52.tar.gz
This version is the version operational at the new production server 
overpass-api.de resp. 46.4.41.83 .
All older versions can be found at
http://dev.overpass-api.de/releases/

Please check in your local environment whether there are unexpected 
problems. This would allow to republish an improved version if necessary.

The core feature is the database compression by default. The compressed 
database with history since 2012-09-12 has currently a size of 254 GB, 
the compressed database without history is about 152 GB. It is planned 
to make this compressed database accesible per cloning, but this doesn't 
work the way it should at the moment, see below.

The release v0.7.52 should also be the base for all future development 
to faciliate later merging.

Therefore, I have removed all completed or abandoned branches from my 
copy of the repository. For the two remaining branches, I will first 
merge from v0.7.52 before doing further development. I would like to ask 
you to also merge v0.7.52 into all branches that you later plan to use 
for pull requests.

The thing I will do next is to pick by hand the necessary changes from 
branch
https://github.com/mmd-osm/Overpass-API/tree/backend_compression_lz4_map
to enable Random_File compression which is useful for databases on extracts.

The thing I will do afterwards is to get branch
https://github.com/drolbr/Overpass-API/tree/out_csv_finetuning
complete. This is a roadblocker to make "out:csv" and "count" 
productive, and there is not that much to do left.

Given that I will have to prepare two workshops for the SotM-US from 
June 6th to June 8th, it is unlikely that much more will happen before 
that date. If possible, I would like to make a similar branch to 
out_csv_finetuning for purely tag based filters to enable the 
development of the date comparator asked for by Richard Welty.

If you have other urgent matters, please let me know. I'm happy to 
change development priorities for greater general benefit.

Cheers,

Roland
