# Nominatim contribution guidelines
-## Workflow
+## Reporting Bugs
-We operate the "Fork & Pull" model explained at
+Bugs can be reported at https://github.com/openstreetmap/Nominatim/issues.
+Please always open a separate issue for each problem. In particular, do
+not add your bugs to closed issues. They may looks similar to you but
+often are completely different from the maintainer's point of view.
+
+## Workflow for Pull Requests
+
+We love to get pull requests from you. We operate the "Fork & Pull" model
+explained at
https://help.github.com/articles/using-pull-requests
You should fork the project into your own repo, create a topic branch
there and then make one or more pull requests back to the openstreetmap repository.
-Your pull requests will then be reviewed and discussed.
+Your pull requests will then be reviewed and discussed. Please be aware
+that you are responsible for your pull requests. You should be prepared
+to get change requests because as the maintainers we have to make sure
+that your contribution fits well with the rest of the code. Please make
+sure that you have time to react to these comments and amend the code or
+engage in a conversion. Do not expect that others will pick up your code,
+it will almost never happen.
+
+Please open a separate pull request for each issue you want to address.
+Don't mix multiple changes. In particular, don't mix style cleanups with
+feature pull requests. If you plan to make larger changes, please open
+an issue first or comment on the appropriate issue already existing so
+that duplicate work can be avoided.
+
+### Using AI-assisted code generators
+
+PRs that include AI-generated content, may that be in code, in the PR
+description or in documentation need to
+
+1. clearly mark the AI-generated sections as such, for example, by
+ mentioning all use of AI in the PR description, and
+2. include proof that you have run the generated code on an actual
+ installation of Nominatim. Adding and excuting tests will not be
+ sufficient. You need to show that the code actually solves the problem
+ the PR claims to solve.

## Coding style
Nominatim historically hasn't followed a particular coding style but we
-are in process of consolodating the style. The following rules apply:
+are in process of consolidating the style. The following rules apply:
* Python code uses the official Python style
- * indention
+ * indentation
* SQL use 2 spaces
- * all other use files TABs
+ * all other file types use 4 spaces
* [BSD style](https://en.wikipedia.org/wiki/Indent_style#Allman_style) for braces
* spaces
* spaces before and after equal signs and operators
* leave out space between a function name and bracket
but add one between control statement(if, while, etc.) and bracket
+The coding style is enforced with pylint. It can be tested with:
-This coding style must be applied to any new or changed code. You are also
-welcome to fix the coding style of existing code but please submit separate
-PRs for this.

## Testing

+## Releases
+
+Nominatim follows semantic versioning. Major releases are done for large changes
+that require (or at least strongly recommend) a reimport of the databases.
+Minor releases can usually be applied to existing databases. Patch releases
+contain bug fixes only and are released from a separate branch where the
+relevant changes are cherry-picked from the master branch.
+
+Checklist for releases:
+
+* [ ] increase versions in
+ * `src/nominatim_api/version.py`
+ * `src/nominatim_db/version.py`
+ * CMakeLists.txt
+* [ ] update `ChangeLog` (copy information from patch releases from release branch)
+* [ ] complete `docs/admin/Migration.md`
+* [ ] update EOL dates in `SECURITY.md`
+* [ ] commit and make sure CI tests pass
+* [ ] test migration
+ * download, build and import previous version
+ * migrate using master version
+ * run updates using master version
+* [ ] prepare tarball:
+ * `git clone --recursive https://github.com/osm-search/Nominatim` (switch to right branch!)
+ * `rm -r .git* osm2pgsql/.git*`
+ * copy country data into `data/`
+ * add version to base directory and package
+* [ ] upload tarball to https://nominatim.org
+* [ ] prepare documentation
+ * check out new docs branch
+ * change git checkout instructions to tarball download instructions or adapt version on existing ones
+ * build documentation and copy to https://github.com/osm-search/nominatim-org-site
+ * add new version to history
+* [ ] check release tarball
+ * download tarball as per new documentation instructions
+ * compile and import Nominatim
+ * run `nominatim --version` to confirm correct version
+* [ ] tag new release and add a release on github.com
+* [ ] build pip packages and upload to pypi
