Satsuki

Satsuki (pronounced SAHT-ski) is a Python package that helps manage GitHub releases and release assets. Satsuki is especially useful paired with Continuous Integration/ Continuous Deployment (CI/CD) tools such as Travis CI and AppVeyor.

Why not just use the Travis CI GitHub Releases provider? Good question. The simple answer is that the provider doesn't work very well yet. In specific, you can't update an existing release or add files (assets) to a release or provide a release message and a release asset at the same time.

Satsuki and Travis CI Example

This example shows setting up Travis CI with your GitHub OAUTH token for use by Satsuki, and then creating releases and uploading assets.

Step 1: Encrypt OAUTH Token

Using Travis's command line tool, encrypt your OAUTH token with the environment variable name. NOTE: Travis CI encrypts values on a repo by repo basis. Thus, a value encrypted for one repo will not work in another repo, even if commonly owned.

$ cd myrepodir
$ travis encrypt SATS_TOKEN=YOUR_GITHUB_OATH_TOKEN
Please add the following to your .travis.yml file:

secure: "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"

Step 2: Add Token to Travis YAML

Now, we'll add this secure value to the .travis.yml file in our repo. Only Travis CI can decrypt this value now. (Although this shows Python as the language, Satsuki will work with projects in other languages as long as you install Python 3 and pip.)

language: python
sudo: false
env:
  global:
    - secure: 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

Step 3: Setup the Travis YAML Script Step

We'll use the script step to build an application into an OS/machine specific binary using GravityBee.

install:
  - pip install gravitybee satsuki
script:
  - gravitybee --src-dir src --clean

Step 4: Setup the Travis YAML Before Deploy Step

Next, ssign values to environment variables so that Satsuki can use them to create the release and tag. Optionally, you can also use special variables in Satsuki that will be substituted with values from GravityBee. See Variable Substitution below.

before_deploy:
  - export SATS_TAG=$(grep "version = " $TRAVIS_BUILD_DIR/setup.cfg | sed "s/version = //")
  - export SATS_BODY="* Here is the message for the release"
  - export SATS_FILE="mysuperapp-1.2.3-standalone-linux-x86_64"

Step 5: Setup the Travis YAML Deploy Step

Everything should be set now to deploy.

deploy:
  - provider: script
    script: satsuki
    skip_cleanup: true
    on:
      branch: master
      repo: YakDriver/mysuperapp
      python: "3.6"

Now if you've enabled your repo on Travis CI, when you commit to the master branch, if all goes well, you'll get a release with your binary file associated with it.

Reference

Satsuki can be used with command line (CL) options or environment variables, or a mix of both. If both are provided, command line options take precedence.

Options

Using Satsuki, you can create releases. A release is a GitHub feature. However, a release is related to a tag, which is a pure Git feature. (If the tag doesn't exist, Satsuki will create it along with the release.) You can also create assets (e.g., binary files) that are associated with releases. Thus Satsuki has options that relate to each: Asset ==> Release ==> Tag.

Options from each, tag, release, and asset, can be provided at the same time, and Satsuki will attempt to act appropriately on each. For example, in one command you can create a tag, release, and asset.

Release/Satsuki Related

Local logging can be configured in satsuki/logging.conf.

ENV VAR	CL Options	Desciption
SATS_TOKEN	--token	[Required] An OAUTH token with repo access.
SATS_COMMAND	-c, --command	The operation to perform on the GitHub release. Choose from upsert or delete. If delete is selected and a file is provided, the file (release asset) is deleted instead of the release. Default: upsert
SATS_RECREATE_OK	--recreate	[Flag] Indicates whether a release commitish can be updated by deleting and recreating the release. Otherwise, a release cannot be updated with a new commit SHA. If this flag is set, --include-tag is implied. Default: not
SATS_SLUG	-s, --slug	[Required] Either repo and user or the slug (in the form user/repo) must be provided. If not provided, it will default to the value provided by Travis CI, Azure Pipelines or AppVeyor, if any.
SATS_REPO	-r, --repo	[Required] The GitHub repository to work with.
SATS_USER	-u, --user	[Required] The owner of the repository to work with.
SATS_REL_NAME	-n, --rel-name	The name of the release. Available for variable substitution. See below. Default: tag name
SATS_LATEST	--latest	[Required][Flag] Either this option OR --tag must be used. When used, Satsuki will perform any operations on the latest release. Default: Not
SATS_BODY	-b, --body	The message that shows up with releases. Available for variable substitution. See below. Default: Release <tag>
SATS_PRE	-p, --pre	[Flag] Whether or not this release is a prerelease. Default: Not
SATS_DRAFT	-d, --draft	[Flag] Whether or not this release is a draft. Default: Not
SATS_FORCE	--force	[Flag] Force Satsuki to delete items when normally it would not. CAUTION: You could easily delete every release in your repository with this. Default: Not

Tag Related

ENV VAR	CL Options	Desciption
SATS_TAG	-t, --tag	[Required] Either the tag OR the --latest option must be provided. If both are used, tag takes precedence. In finding existing releases, the "tag" value may be either the release ID (e.g., 10746271) or tag name (e.g., v0.1.0). However, if a release ID is provided, and it does not exist, an error will be thrown to avoid creating a tag with an ID-like name. Available for variable substitution. See below. If not provided, will default to the value provided by Travis CI or AppVeyor, if any.
SATS_COMMITISH	--commitish	Can be any branch or commit SHA. Unused if the Git tag already exists. If not provided, it will default to the TRAVIS_COMMIT environment variable provided by Travis CI or BUILD_SOURCEVERSION from Azure Pipelines or APPVEYOR_REPO_COMMIT from AppVeyor, if any. If none is provided, GitHub will default to the default branch.
SATS_INCLUDE_TAG	--include-tag	Whether to delete the tag when deleting the release. If the provided tag does not match a release, the tag will be deleted. If the tag includes a POSIX-style filename pattern match, all tags which aren't associated with releases will be deleted. This is handy for cleaning up tags. If you have many tags to cleanup, you may need to run this multiple times to complete the cleaning. Default: Not

Asset Related

These options can be used multiple times. If there is one label or one MIME type, and multiple files, the same label and MIME type will be applied to each file. Otherwise, there must be the same number of labels and/or MIME types as files, or an error will be thrown.

ENV VAR	CL Options	Desciption
SATS_FILE	-f, --file	File(s) to be uploaded as release asset(s). If the file name contains an asterik (*) it will be treated as a POSIX-style glob and all matching files will be uploaded. This option can be used multiple times to upload multiple files. Default: No file is uploaded.
SATS_LABEL	-l, --label	Label to display for files instead of the file name. Not recommended with multiple file upload since all will share the same label. Available for variable substitution. See below. Default: GitHub will use the raw file name.
SATS_MIME	-m, --mime	The mime type for files. Default: A guess of the file type or application/octet-stream if all else fails.
SATS_FILE_SHA	--file-sha	Whether to create SHA256 hashes for upload files, and either append them to the file label or upload them in a separate file. Valid options are: none, file, and label. Default: none
SATS_FILES_FILE	--files-file	Name of JSON file with information about file(s) to upload. See below. Default: Will look for gravitybee-files.json

Variable Substitution

For certain values, you can optionally include variables that will be substituted using information from GravityBee. Whether variables are replaced depends on all the following conditions being met:

• The GravityBee info file (gravitybee-info.json) is in the current directory.
• The file is correctly formatted JSON.
• The file uses the correct structure defined by GravityBee.
• The variables within the environment variables are spelled correctly and not replaced prior to getting to Satsuki (e.g., by the shell or OS).

If you're having trouble getting substitutions to work, try displaying environment variables (e.g., using env on POSIX systems or SET on Windows) to make sure $s haven't been replaced. On POSIX, use single quotes when setting environment variables to prevent premature substitution.

These are the variables you can use.

VARIABLE	Desciption
$gb_pkg_ver	The version of the package extracted by GravityBee from setup.py or setup.cfg.
$gb_pkg_name	The name of the package extracted by GravityBee from setup.py or setup.cfg, which is often the application name.
$gb_pkg_name_lower	Same as $gb_pkg_name but lowercase.
$gb_sa_app	The name of the binary file, standalone application created by GravityBee.

An example of using substitution.

$ export SATS_TAG='$gb_pkg_ver' # will be replaced with 4.2.6, for example

The Files File

Satsuki also accepts a JSON-formatted file containing information about assets to be uploaded (see the --files-file option above). The file can contain information about multiple files and should contain information about files accessible to Satsuki, with paths relative to the directory in which Satsuki is run. A file in the correct format is generated by GravityBee.

Satsuki will always look in the current directory for a GravityBee files file (gravitybee-files.json). If found, Satsuki will upload the specified files. To avoid this behavior, remove a GravityBee files file from the current directory. You can also use a GravityBee files file in another location, besides the current directory, by using the --files-file flag.

This is an example of the format.

[{'filename': 'gbtestapp-4.2.6-standalone-osx-x86_64',
  'label': 'gbtestapp Standalone Executable (gbtestapp-4.2.6-standalone-osx-x86_64) [GravityBee Build]',
  'mime-type': 'application/x-executable',
  'path': '/path/to/file/gbtestapp-4.2.6-standalone-osx-x86_64'}]

Command-Line Examples

Here is an example of using Satsuki to clean up tags. This command will delete all tags not connected to a release that match the pattern Test-*. To be able to clean tags, Satsuki must be run from the git directory of the repo.

$ satsuki -s "<OWNER>/<REPO>" --token <YOUR_GITHUB_OATH_TOKEN> \
--tag Test-* -c delete -v

Delete the release asset with the filename release-asset.exe from the release tagged with Test-ve8226c.

$ satsuki -s "<OWNER>/<REPO>" --token <YOUR_GITHUB_OATH_TOKEN> \
--tag Test-ve8226c -c delete -v --file release-asset.exe

Create a new release and tag called testtag based on the given commit SHA, and upload the file release-asset.exe as an asset of the new release.

$ satsuki -s "<OWNER>/<REPO>" --token <YOUR_GITHUB_OATH_TOKEN> \
--tag testtag --commitish 42b8b9f3f44e0a11071cd3c56eaed29a305c3339 \
-v --file release-asset.exe

Delete the release called 1.2.3.

$ satsuki -s "<OWNER>/<REPO>" --token <YOUR_GITHUB_OATH_TOKEN> \
--tag 1.2.3 -c delete -v

Delete the release and local and/or remote tags called 1.2.3.

$ satsuki -s "<OWNER>/<REPO>" --token <YOUR_GITHUB_OATH_TOKEN> \
--tag 1.2.3 -c delete -v --include-tag

Delete ALL releases and local and/or remote tags matching Test-*. USE CAUTION!

$ satsuki -s "<OWNER>/<REPO>" --token <YOUR_GITHUB_OATH_TOKEN> \
--tag Test-* -v -c delete --include-tag --force
