## How to add new functions
|
||
|
|
|
||
|
|
Try to put as little logic in the SQL extension as possible and
|
||
|
|
just use it as a wrapper to the Python module functionality.
|
||
|
|
|
||
|
|
### Python
|
||
|
|
|
||
|
|
...
|
||
|
|
|
||
|
|
### SQL
|
||
|
|
|
||
|
|
* Generate a **new subfolder version** for `sql` and `test` folders to define the new functions and tests
|
||
|
|
* Use symlinks to avoid file duplication between versions that don't update them
|
||
|
|
* Add or upgrade your SQL server functions
|
||
|
|
* Create tests for the client and server functions -- at least, to check that those are created
|
||
|
|
|
||
|
|
* Generate the **upgrade and downgrade files** for the extension for both client and server
|
||
|
|
|
||
|
|
* Update the control files and the Makefiles to generate the complete SQL file for the new created version
|
||
|
|
* These new version file (`crankshaft--X.Y.Z.sql`)
|
||
|
|
must be pushed and frozen. You should add it to the `.gitignore` file.
|
||
|
|
|
||
|
|
* Update the public docs! ;-)

## Naming things

# SQL
|
||
|
|
|
||
|
|
Use snake case (i.e. `snake_case` and not `CamelCase`) for all
|
||
|
|
functions. Prefix functions intended for public use with `cdb_`
|
||
|
|
and private functions (to be used only internally inside
|
||
|
|
the extension) with `_cdb_`.
