Hello Everyone I’ve had a mild issue about

ShellTask

, in which a

git clone

command doesn’t return some of the stdout lines (despite using

return_all=True

). The command is as follows:

git clone https://{some_url}.git dbt_project -v -b master --depth 1

. Running it from bash logs the following to stdout:

Cloning into 'dbt_project'...
POST git-upload-pack (156 bytes)
POST git-upload-pack (165 bytes)
remote: Counting objects: 40, done.
remote: Compressing objects: 100% (34/34), done.
remote: Total 40 (delta 2), reused 0 (delta 0)
Unpacking objects: 100% (40/40), done.

While running the same command through

ShellTask

, and iterating over the resulting list of stdout lines logs the following:

[2020-03-19 09:57:50,792] INFO - prefect.Task: print_task | Cloning into 'dbt_project'...
[2020-03-19 09:57:50,792] INFO - prefect.Task: print_task | POST git-upload-pack (168 bytes)
[2020-03-19 09:57:50,793] INFO - prefect.Task: print_task | POST git-upload-pack (177 bytes)

By any means, I am not well versed on bash, and this may very well be an issue about how

git clone

logs to stdout. Wondering if anybody else encountered a similar issue, and if they managed to come up with a fix?

I guess it's possible that git is printing that missing output only if it detects an interactive session, or that the

ShellTask

is not picking up stderr altogether from the subprocess

Thanks, git was indeed printing the progress status to stderr, which isn’t picked up by

ShellTask

. The

--progress

flag forces git to print progress logs to stdout, as far as I understand.
