* chore: Remove `SYS_PTRACE` capability from docs and configs
* chore: Remove `SYS_PTRACE` capability from tests
Doesn't seem to be required. It was originally added when the original change detection feature PR apparently needed it to function.
This helper was to support an earlier ENV for SASL auth support. When extracting logic into individual helpers, it was assumed this was separate from relay support, which it appears was not the case.
---
The `SASL_PASSWD` ENV is specified in tests but no longer used. There is no `external-domain.com` relay configured or tested against anywhere in the project.
The ENV was likely used in tests prior to improved relay support that allowed for adding more than a single set of relay credentials.
---
It likewise has no real relevance anywhere else outside of `relay.sh` as it's the only portion of code to operate with it.
It's only relevant for SASL auth as an SMTP client, not the SMTP server (`smtpd`) SASL support that is delegated to Dovecot. Functionality has been completely migrated into `relay.sh` as a result.
Documentation is poor for this ENV, it is unlikely in wide use? Should consider for removal.
---
The ENV has been dependent upon `RELAY_HOST` to actually enable postfix to use `/etc/postfix/sasl_passwd`, thus not likely relevant in existing setups?
---
Migrate `/etc/postfix/sasl_passwd` check from `tests.bats` as it belongs to relay tests.
* tests(fix): Increase some timeouts
Running tests locally via a VM these tests would fail sometimes due to the time from being queued and Amavis actually processing being roughly around 30 seconds.
There should be no harm in raising this to 60 seconds, other than delaying a failure case which will ripple through other time sensitive tests.
It's better to pass when functionality is actually correct but just needs a bit longer to complete.
* tests(fix): Don't setup an invalid hostname
During container startup `helpers/dns.sh` would panic with `hostname -f` failing.
Dropping `--domainname` for this container is fine and does not affect the point of it's test.
---
It's unclear why this does not occur in CI. Possibly changes within the docker daemon since as CI runs docker on Ubuntu 20.04? (2020).
For clarity, this may be equivalent to setting a hostname of `domain.com.domain.com`, or `--hostname` value truncated the NIS domain (`--domainname`) of the same value.
IIRC, it would still fail with both options using different values if `--hostname` was multi-label. I believe I've documented how non-deterministic these options can be across different environments.
`--hostname` should be preferred. There doesn't seem to be any reason to actually need `--domainname` (which is NIS domain name, unrelated to the DNS domain name). We still need to properly investigate reworking our ENV support that `dns.sh` manages.
---
Containers were also not removing themselves after failures either (missing teardown). Which would cause problems when running tests again.
* chore: Normalize white-space
Sets a consistent indent size of 2 spaces. Previously this varied a fair bit, sometimes with tabs or mixed tabs and spaces.
Some formatting with blank lines.
Easier to review with white-space in diff ignored. Some minor edits besides blank lines, but no change in functionality.
* fix: `setup.sh` target container under test
Some of the `setup.sh` commands did not specify the container which was problematic if another `docker-mailserver` container was running, causing test failures.
This probably doesn't help with `test/no_container.bats`, but at least prevents `test/tests.bats` failing at this point.
Previously, only postfix-relaymap.cf and postfix-accounts.cf would be
used to populate the relayhost_map file.
Now, also use postfix-virtual.cf when present. To me, there is nothing
absurd about sending mail "From:" a virtual account (or more
specifically its domain) so it makes sense that when a $RELAY_HOST is
defined it should be used for virtual accounts as well.
check-for-changes.sh did not have a special case to handle lines in
postfix-relaymap.cf consisting of only a domain (indicating that said
domain should never be relayed). This case is handled by
start-mailserver.sh so when such a line existed, things would work well
until a config file update was detected by check-for-changes.sh. After
that, the generated relayhost_map file would be corrupted.
Fixed by factoring a 'populate_relayhost_map' function out of
start-mailserver.sh and into helper_functions.sh and reusing it in
check-for-changes.sh.
Note: There are certainly quite a few more pieces of code that could be
refactored in a similar fashion.
Note2: check-for-changes.sh would previously never update the
relayhost_map file when $ENABLE_LDAP was set to 1. I don't think this
was intended —there is after all no such condition in
start-mailserver.sh— and so this condition no longer applies.
