SymPy Bot

The goal of SymPy Bot is to do all the automated testing for a pull request and report back into the pull request with the results.

So far one has to run the bot manually, but eventually we would like to create a web service for it.

Usage

List all pull requests, sorted by date:

./sympy-bot list

Make an automatic review of a pull request:

./sympy-bot review 268

This will run all tests and then comment in the pull request (under your name) with the results.

To review all open pull requests, do:

./sympy-bot review all

to only review mergeable pull requests, do:

./sympy-bot review mergeable

Tips

By default, the sympy repository is fully downloaded from the web, so you don't need to have any local copy. However, if you do have a local copy already, you can skip most of the download (which might take a few minutes on slower connections) by passing a --reference option to sympy-bot:

./sympy-bot --reference ~/repo/git/sympy review 268

This gets passed to git, see git clone --help for more information. Then sympy-bot starts testing the branch immediately, even if you have a slower connections.

Configuration

You can avoid providing your username and password, give a reference to a local clone of SymPy's repository, or use a custom test command every time when you use SymPy Bot by creating a configuration file for SymPy Bot at ~/.sympy/sympy-bot.conf and adding the following lines to it:

user = "your user name"
token = "your GitHub API token"
reference = "path to a local clone of SymPy's repository"
repository = "remote SymPy's repository (default is sympy/sympy)"
interpreter = "interpreter to run tests with (default is 'python')"
testcommand = "command to run tests with (default is 'setup.py test')"

Note that with configuration file you can use only token-based GitHub authentication mechanism (this is for your safety, but anyway make sure that the configuration file has proper permissions assigned, e.g. 600). You may leave any value that you don't want to include empty, and the default will be used. If you supply a username and not an API token, then sympy-bot will ask you for your GitHub password on each invocation.

You can get your GitHub API token by going to https://github.com/account/admin.

Foreign repositories

SymPy Bot can be also used with other remote repository than sympy/sympy. You can change the remote with -R flag to sympy-bot or by setting repository in configuration file. The new remote doesn't have to be SymPy's repository, but any repository on GitHub. Note that in this case you man need to setup customized testcommand.

Custom Master Commit

By default, sympy-bot merges with master before testing, failing if the merge fails. You can customize this behavior with the -m option to sympy-bot. Pass any valid git commit name to this option, and it will use it to merge the master branch. The default is origin/master, which is the current master. If you don't want to merge at all, pass HEAD, which will perform a noop merge against the branch you are testing.

If you use --reference, git will pull in all commits from the local repository. Thus, you can merge with commits that are not in the official sympy/sympy repository by using this and passing the SHA1 of the commit you want.

This is also useful for bisecting problems with SymPy Bot. Simply use git to bisect in your local SymPy repository and pass the SHA1's it picks to sympy-bot -n -m.

Web interface integration with github

This way is a bit complicated in set up than previous (poll github for new pulls), but that will update information about pulls in real time.

SymPy Bot web-interface (which located in under web/) supports integration with github via mechanism called hooks http://developer.github.com/v3/repos/hooks/

To use that feature you need to follow these steps:

Go to http://example.com/upload_pull, sign in as administrator and press generate button. After that, all admins will recieve notification with secret URL (you can see a log of all generations in table on that page)
You need to tell github to use this URL, so here steps (replace username and repo with you values):
- Go to https://github.com/user/repo/admin/hooks
- Click on WebHook URLs and add secret URL there.
- Find the hook that you want to modify by:
```
curl -u username https://api.github.com/repos/username/repo/hooks
```
  the id field gives the hook ID, copy and paste the path in the "url" field into the command:
```
curl -u username -d '{ "events": [ "pull_request" ] }'
https://api.github.com/repos/username/repo/hooks/ID
```
  You will see that the "events" part:
```
"events": [
    "push"
],
```
  changed to:
```
"events": [
    "pull_request"
],
```
