Feels like we've gone back and forth a few times on this method already. Have you had a chance to test this under both Python 2 and 3? |
|
I haven't tested it under Python 3, no. Is there already a simple way to do so inside a Docker container? (I'll install Python 3 in a VM if I absolutely have to, but I'd rather avoid it). |
|
OK, I've added checks to the integration test and can confirm that it runs under Python 3.3 (a flurry of failures in other tests notwithstanding; think that file needs a bit of love in general.) |
Docker introduced newlines in stream output in version 0.9 (moby/moby#4276), but not to all endpoints - POST /images/create, for example, does not include them. This reverts to the old, less pleasant implementation of _stream_helper(), with a manual check for newlines to fix the problem described in docker#176 and fixed in docker#184, without the accompanying regression. It should work against Docker 0.8, 0.9 and 0.10, both when building and when pulling.

LGTM |

We've been back and forth on this several times indeed. If this has been successfully tested (on all methods!) with both Python 2.x and 3.x, talking to Docker daemons 0.7, 0.8, 0.9 and 0.10, then I'm ok with the change. |
|
This works well on 0.11. we need this fix. |
|
I've tested it by hand by running the integration test against 0.8.0, 0.9.0 and 0.10.0 and Python 2.7/3.3, but is there a more robust/automated way to do it? (Related: other parts of the integration test break for me - is it maintained?) |
|
LGTM then. Thanks a lot! |

Docker introduced newlines in stream output in version 0.9 (moby/moby#4276), but not to all endpoints -
POST /images/create, for example, does not include them. This means that #184, though it fixed #176, introduced a regression inclient.pull('ubuntu', stream=True), as reported in #199.This reverts to the old, less pleasant implementation of
_stream_helper(), with a manual check for newlines to fix the original problem, without the accompanying regression. It should work against Docker 0.8, 0.9 and 0.10, both when building and when pulling.Fixes #199.
