Description Robert Scheck 2021-10-18 17:59:17 UTC

Description of problem:
NGINX logrotate may end like this:

--- snipp ---
/etc/cron.daily/logrotate:

error: Compressing program wrote following message to stderr when compressing log /var/log/nginx/access.log-20211017:
gzip: stdin: file size changed while zipping
--- snapp ---

Version-Release number of selected component (if applicable):
nginx-1.14.1-9.module+el8.0.0+4108+af250afe.x86_64

How reproducible:
Always.

Steps to Reproduce:
1. Ensure NGINX logging to /var/log/nginx/access.log

Actual results:
NGINX logrotate leads to "gzip: stdin: file size changed while zipping"

Expected results:
NGINX logrotate must not lead to "gzip: stdin: file size changed while zipping"

Additional info:
From my point of view, this also affects Fedora and CentOS 9 Stream.

Cross-filed case #03060134 at the Red Hat customer portal.

Fix in Fedora: https://src.fedoraproject.org/rpms/nginx/c/3ba5cb0faa010f2c7281404c1f1c8fe4ea0e657c?branch=rawhide

Comment 3 Joe Orton 2021-11-02 13:40:03 UTC

Thanks for the report and upstrema link.

Note that nginx:1.14 is already retired so we'd likely fix this only for nginx:1.20 unless there is a specific need for it in 1.18 as well?

Comment 4 Robert Scheck 2021-11-02 13:57:15 UTC

The issue affects any nginx version, thus also nginx:1.20 and nginx:1.18. Given I don't see nginx:1.20 there yet, a fix for nginx:1.18 would be really appreciated.
