# Release & Deployment Process
|
|
|
|
Please read the Working Process/Quickstart Guide in README.md
|
|
and the Development guidelines in CONTRIBUTING.md.
|
|
|
|
The release process of a new version of the extension
|
|
shall be performed by the designated *Release Manager*.
|
|
|
|
Note that we expect to gradually automate more of this process.
|
|
|
|
Having checked PR to be released it shall be
|
|
merged back into the `master` branch to prepare the new release.
|
|
|
|
The version number in `pg/cranckshaft.control` must first be updated.
|
|
To do so [Semantic Versioning 2.0](http://semver.org/) is in order.
|
|
|
|
Thew `NEWS.md` will be updated.
|
|
|
|
We now will explain the process for the case of backwards-compatible
|
|
releases (updating the minor or patch version numbers).
|
|
|
|
TODO: document the complex case of major releases.
|
|
|
|
The next command must be executed to produce the main installation
|
|
script for the new release, `release/cranckshaft--X.Y.Z.sql` and
|
|
also to copy the python package to `release/python/X.Y.Z/crankshaft`.
|
|
|
|
```
|
|
make release
|
|
```
|
|
|
|
Then, the release manager shall produce upgrade and downgrade scripts
|
|
to migrate to/from the previous release. In the case of minor/patch
|
|
releases this simply consist in extracting the functions that have changed
|
|
and placing them in the proper `release/cranckshaft--X.Y.Z--A.B.C.sql`
|
|
file.
|
|
|
|
The new release can be deployed for staging/smoke tests with this command:
|
|
|
|
```
|
|
sudo make deploy
|
|
```
|
|
|
|
This will copy the current 'X.Y.Z' released version of the extension to
|
|
PostgreSQL. The corresponding Python extension will be installed in a
|
|
virtual environment in `envs/X.Y.Z`.
|
|
|
|
It can be activated with:
|
|
|
|
```
|
|
source envs/X.Y.Z/bin/activate
|
|
```
|
|
|
|
But note that this is needed only for using the package directly;
|
|
the 'X.Y.Z' version of the extension will automatically use the
|
|
python package from this virtual environment.
|
|
|
|
The `sudo make deploy` operation can be also used for installing
|
|
the new version after it has been released.
|
|
|
|
To install a specific version 'X.Y.Z' different from the current one
|
|
(which must be present in `releases/`) you can:
|
|
|
|
```
|
|
sudo make deploy RELEASE_VERSION=X.Y.Z
|
|
```
|
|
|
|
TODO: testing procedure for the new release.
|
|
|
|
TODO: procedure for staging deployment.
|
|
|
|
TODO: procedure for merging to master, tagging and deploying
|
|
in production.
|
|
|
|
## Relevant release & deployment tasks available in the Makefile
|
|
|
|
```
|
|
* `make help` show a short description of the available targets
|
|
|
|
* `make release` will generate a new release (version number defined in
|
|
`src/pg/crankshaft.control`) into `release/`.
|
|
Intended for use by the release manager.
|
|
|
|
* `sudo make deploy` will install the current release X.Y.Z from the
|
|
`release/` files into PostgreSQL and a Python virtual environment
|
|
`envs/X.Y.Z`.
|
|
Intended for use by the release manager and deployment jobs.
|
|
|
|
* `sudo make deploy RELEASE_VERSION=X.Y.Z` will install specified version
|
|
previously generated in `release/`
|
|
into PostgreSQL and a Python virtual environment `envs/X.Y.Z`.
|
|
Intended for use by the release manager and deployment jobs.
|
|
