| mso | hi all, can someone point me into the right direction ? | 02:05 |
|---|---|---|
| mso | i have a datasoruce "nocloud" that i can (re)run when the machine is up, however, it does not work during boot | 02:06 |
| mso | the nocloud seed is configured in the cloud.cfg | 02:07 |
| mso | i am actualy totally lost where to go now, the environment is running ovirt and i am trying to deploy machines through foreman | 02:08 |

| kol | Hello , where do I make changes in cloud-init ? I see a cloud-config.txt file , but it is always empty even when i run cloud-init , i'm not able to figure it out :/ | 07:30 |
| kol | or is it like it like i have to edit in etc / cloud . cloud.cfg ? | 07:30 |

| smoser | kol, you can put config files in /etc/cloud/cloud.cfg.d or edit /etc/cloud/cloud.cfg. | 13:59 |
| smoser | /var/lib/cloud/instance/cloud-config.txt is written by what is read in from user-data. | 13:59 |
| smoser | if you've not passed any '#cloud-config' in user-datta, then it will be empty. | 13:59 |

| Odd_Bloke | smoser: LC_ALL was set to C because that's what it is set to in some clouds (e.g. Azure), and it changes Python's encoding/decoding behaviour. | 14:08 |
| smoser | hm.. | 14:10 |
| Odd_Bloke | smoser: So I think with your change, the test in http://bazaar.launchpad.net/~cloud-init-dev/cloud-init/trunk/revision/1059.1.2 would pass without my fix. | 14:10 |
| Odd_Bloke | s/the test/the test I added/ | 14:10 |
| smoser | why does encode/decode change? | 14:10 |
| smoser | is it just that encode() changes ? with no 'utf-8' arg ? | 14:11 |
| Odd_Bloke | Because Python determines the default encoding it should use from the environment. | 14:11 |
| Odd_Bloke | (If you don't specify one) | 14:11 |
| smoser | right. so we should always be specifying one. | 14:11 |
| smoser | there is lots of slop right now in that respect. | 14:11 |
| Odd_Bloke | smoser: Agreed; setting LC_ALL=C will help catch places we're assuming that encoding will be UTF-8 when it may actually end up as something else. | 14:12 |
| smoser | Odd_Bloke, yes, it will . and apparently will also catch places in other code (httpretty) | 14:13 |
| smoser | which idont want to catch :) | 14:13 |
| Odd_Bloke | smoser: :) | 14:14 |
| Odd_Bloke | smoser: Can we pin to an older version of HTTPretty in the meantime, or do we need some of the more recent behaviour? | 14:14 |
| smoser | 0.8.0 would be fine. | 14:15 |
| smoser | and we could pin to that. | 14:15 |
| smoser | (that is what is in vivid) | 14:15 |
| smoser | at some point in the future, it might be useful to have tox environments that describe versions of dependencies on a particular release | 14:15 |
| smoser | so i could: | 14:16 |
| smoser | tox -e trusty-34 | 14:16 |
| smoser | er.. trusty-py34 | 14:16 |
| smoser | hey, strikov | 14:39 |
| smoser | so yeah, looking at bug 1424900 | 14:39 |
| strikov | hey | 14:39 |
| smoser | the issue is that python2 made all this magic. | 14:39 |
| smoser | and we didn't have to think about what might be in content of a read() (whether that be http or file) | 14:39 |
| smoser | all "just worked" | 14:39 |
| smoser | but in python3 you have to be much more careful | 14:40 |
| strikov | correct, you need to know what you read | 14:40 |
| strikov | because when you read ascii but think that you read utf -- bad things happen | 14:40 |
| smoser | and the python3 port of cloud-init tried to keep us from having to know such things. | 14:41 |
| smoser | but unfortunately that just isntt going to work | 14:41 |
| strikov | well, it treated everything as utf | 14:41 |
| strikov | basically we don't want t have binary -> string -> binary convertion at all for userdata | 14:42 |
| strikov | can we read it to binary objject somehow? | 14:42 |
| strikov | because to me it looks like python-requests converting userdata to utf-8 string | 14:43 |
| smoser | i think we need to be able to | 14:43 |
| strikov | when you call it from readurl | 14:43 |
| smoser | python-requests definitely does support reading binary data | 14:43 |
| smoser | as i use that for cloud-init | 14:43 |
| strikov | maybe requests can handle that for us? | 14:44 |
| smoser | but i think the way we're using it doesnt | 14:44 |
| smoser | er... above, "as i use that for simplestreams" | 14:44 |
| strikov | yeah, i got it | 14:44 |
| strikov | OR we may generate correct utf-8 bitstream on the server | 14:45 |
| strikov | maybe that's the better way | 14:45 |
| strikov | because right now (I assume) server generates ascii bitstream | 14:45 |
| strikov | i.e. raw bytes | 14:45 |
| strikov | hm, i thought a bit and server-based way seems wrong | 14:46 |
| strikov | smoser: I wonder why userdata content is marked as text/html on metadata server | 14:55 |
| strikov | smoser: Not sure, but marking differently may solve the issue | 14:56 |
| smoser | well, we need to treat it as bytes. | 14:57 |
| smoser | basically, we need to treat as bytes, and try to uncompress, if that doesnt work, then try to encode as utf-8 | 14:57 |
| strikov | smoser: how about that; read_url returns bytes all the time; we have default translator (http://bazaar.launchpad.net/~cloud-init-dev/cloud-init/trunk/view/head:/cloudinit/sources/helpers/openstack.py#L256) which convert data to utf-8 string; userdata is the only field which doesn't use this translator | 15:00 |
| strikov | smoser: url_helper.py has UrlResponse object; right now it has only contents() method which refers to _response.text of python-requests; we may add raw() method which would refer to _reponse.raw which is a file object | 15:07 |
| smoser | strikov, right | 15:08 |
| smoser | strikov, i was investigating that | 15:08 |
| smoser | http://paste.ubuntu.com/10409455/ | 15:08 |
| smoser | that is where i was right now | 15:08 |
| smoser | basically doing raw.read() rather than .text | 15:08 |
| strikov | smoser: awesome! | 15:13 |
