Teams webhook (extra/gitdiff-msteams.sh) - max message size problem

mopi3456 · 21 November 2024 09:54

Hi

We use:
Oxidized-web v.0.14.0, Oxidized v.0.30.1

Sometimes the diffs get very large and hit the max for teams webhooks ¹

I am sadly not proefficient in bash, but would like to do a tweak with one of two solution:
a: cut of the git output before the max message size and add a message like “Commit output truncated to fit the 28KB limit.”
b: create and send multiple messages each under 28KB

I’m writing here in the hope that somebody else might have made such modifications in their environment.

I will do a pull request to get this into oxidized, but if it does not get accepted, i post here for others to use.
I created a solution, and spiced it up with a link to our internal github to view the diff:

github.com

mopi3456/oxidized/blob/new-teams-webhook/extra/gitdiff-msteams.sh

#!/bin/bash
# Posts a git diff to MS Team Channel using webhooks
#
# Usage:
#   Make sure jq and curl are installed.
#   Save this script in /var/lib/oxidized/extra/
#   Add to oxidized config:
#
# hooks:
#  ms_teams_webhook:
#    type: exec
#    events: [post_store]
#    cmd: '/var/lib/oxidized/extra/gitdiff-msteams.sh'
#    async: true
#    timeout: 120
#
# Add webhook to your MS Teams channel and set the next variable to the full url
