pgsql: invalid byte sequence for encoding "UTF8": 0x00 when updating the last error message on repo table for corrupt repo

Created by: mike-r-mclaughlin

• Sourcegraph version: 3.27.4

Steps to reproduce:

Unclear. Requires a "corrupt" git repository. Errors in gitserver at the time show:

fatal: unable to read `<git_sha>`
aborting due to possible repository corruption on the remote side

on pgsql pod we see:

2021-04-29 15:11:20.085 GMT [3272] ERROR:  invalid byte sequence for encoding "UTF8": 0x00

We see a similar error when we try to do a git clone from the command line.

Expected behavior:

No error in the pgsql logs

Actual behavior:

Error is displayed in the pgsql logs:

2021-04-29 15:11:20.085 GMT [3272] ERROR:  invalid byte sequence for encoding "UTF8": **0x00**
