2019-05-16 05:40:32 UTC - Jin Choi: One question: I have a web action which emits an HTML as the result. The thing is, even if I `curl` it with `--compressed` option the HTML comes in the plain text regarding the headers. Using Chrome browser as a client doesn't make a change. So, can I have my web action's result encoded in gzip in response?

2019-05-16 07:08:03 UTC - Rodric Rabbah: If the action compressed the output and base64 encoded it, and sets the proper header, I’d expect it to work.

2019-05-16 07:13:35 UTC - Dominic Kim: @Jin Choi I am not sure this is relevant to your case, but when I download `csv` file via a web action, I used following headers:
```
'headers': {
'Content-Type': 'text/csv',
'content-length': str(len(results)),
'Content-Encoding': 'UTF-32',
'charset': 'UTF-32LE',
'Content-Disposition': 'attachment;filename=ExportedData.csv'
},
```

2019-05-16 07:15:02 UTC - Dominic Kim: You may need more headers for it.

2019-05-16 07:26:13 UTC - Jin Choi: For Nginx, it's just about turning on/off an option for gzip, isn't it?
https://openwhisk-team.slack.com/archives/C3UDXSFA6/p1557991573054100?thread_ts=1557990483.050700&cid=C3UDXSFA6
----
2019-05-16 07:27:54 UTC - Jin Choi: Whether you request a specific Content-Encoding is a different matter from whether you get a result in the requested format.
What do you see in the response header for the action call?

2019-05-16 07:29:24 UTC - Dominic Kim: I am trying to enable gzip compression in a webaciton, how can I confirm the html is passed with compressions in chrome?

----
2019-05-16 07:30:05 UTC - Jin Choi: I think you need an extension in Chrome to be able to tweak the options. Why don't you use `curl` on terminal?

----
2019-05-16 07:36:37 UTC - Jin Choi: `-H "Accept-Encoding: gzip"` on curl option was all you needed to see the `Content-Encoding: gzip` on response header, wasn't it? Did you do something special on your action code for gzip?

2019-05-16 15:27:05 UTC - Robert Munteanu: Hi!
I come here from <ma...@infra.apache.org> where I was told that the OpenWhisk project has some integration around Slack which is based on Functions. If that is correct? If it is, where can I find out more details about it? In Apache Sling we are exploring the idea of running our own bots for GitHub integration but don't want to manage the infrastructure so I'm interested in what others are doing.
Thanks!

2019-05-16 15:51:47 UTC - Dave Grove: Hi @Robert Munteanu I am aware of two slack integrations that use functions. We’ve linked our TravisCI testing to slack notifications using <https://github.com/rabbah/travis-to-slack>. I think we also have a Slack signup process that automates allowing people to join our slack that uses functions as a backend (I don’t know the details of how this works). I think @Rodric Rabbah has made some changes to the Slack/Github integration in the last couple of months, so he may be able to tell you more. our <#C3W9D3UM8|dev> and #dev-pr channel get notified on github operations.

2019-05-16 15:52:21 UTC - Dave Grove: @Rodric Rabbah also built automation that sends a daily digest of slack to our dev list. I think that is also based on functions

2019-05-16 15:55:52 UTC - Robert Munteanu: Thanks @Dave Grove! I would be interested in getting more details about how they are implemented and where they are 'hosted'. Hopefully @Rodric Rabbah has that

----
2019-05-16 16:12:03 UTC - Rodric Rabbah: Hi Robert. Are you asking if there’s an Apache hosted openwhisk/functions service to use? Or what functions already exist for project management that you might be able to reuse?
