Description Pablo Mendez Hernandez 2024-02-21 19:14:21 UTC
Description of problem:

When trying to use `capsule-certs-generate` concurrently (using Ansible, for example) to install several capsules at the same time, it fails with this error:

```
Traceback (most recent call last):
File "/bin/katello-ssl-tool", line 11, in <module>
load_entry_point('Katello-Certs-Tools==2.9.0', 'console_scripts', 'katello-ssl-tool')()
File "/usr/lib/python3.6/site-packages/katello_certs_tools/katello_ssl_tool.py", line 955, in main
_main()
File "/usr/lib/python3.6/site-packages/katello_certs_tools/katello_ssl_tool.py", line 924, in _main
genServerRpm(DEFS, options.verbose)
File "/usr/lib/python3.6/site-packages/katello_certs_tools/katello_ssl_tool.py", line 828, in genServerRpm
os.unlink(postun_scriptlet)
FileNotFoundError: [Errno 2] No such file or directory: '/root/ssl-build/postun.scriptlet'
```

The reason for it is that every execution of the command "shares" the `postun.scriptlet` making it impossible to manage it atomically.


Version-Release number of selected component (if applicable):

- 6.15
- Stream

I'm currently investigating in which other releases this is an issue (I have memories of this since at least 6.13, but I'll double check and create clones if needed).


How reproducible:

Always


Steps to Reproduce:
1. Run the following code in parallel for two of more capsules:

capsule-certs-generate --certs-tar /var/www/html/pub/capsule-1.example.com-certs.tar --foreman-proxy-fqdn capsule-1.example.com

capsule-certs-generate --certs-tar /var/www/html/pub/capsule-2.example.com-certs.tar --foreman-proxy-fqdn capsule-2.example.com

. . .

2.
3.

Actual results:

```

/root/ssl-build/capsule-X.example.redhat.com/capsule-X.example.com-puppet-client-1.0-1.src.rpm

Traceback (most recent call last):
File "/bin/katello-ssl-tool", line 11, in <module>

_main()
File "/usr/lib/python3.6/site-packages/katello_certs_tools/katello_ssl_tool.py", line 924, in _main
genServerRpm(DEFS, options.verbose)
File "/usr/lib/python3.6/site-packages/katello_certs_tools/katello_ssl_tool.py", line 828, in genServerRpm
os.unlink(postun_scriptlet)
FileNotFoundError: [Errno 2] No such file or directory: '/root/ssl-build/postun.scriptlet'
. . .
```


Expected results:

Certs are generated.


Additional info:

I've implemented a fix:

https://github.com/Katello/katello-certs-tools/pull/46

which will create the `postun.scriptlet` file inside each capsule directory created on top of `/root/ssl-build/`.

I've checked that the bug exists at least since Satellite 6.11.
