* chore: Only replace `CHKSUM_FILE` when a change has been processed
* chore: Change Detection service should be the last daemon started
* chore: Remove 10 second startup delay for change detector
There should be no concern with conflicts as any writes should have already been done by the time this daemon service is started.
* tests(fix): `smtp_delivery.bats` must wait for Amavis
The change event for adding a user can be processed much sooner now, which means Amavis may not yet be ready.
Added extra condition to wait on at least the Amavis port being reachable, and some failure asserts with the mail queue to better catch / debug when this problem occurs.
* chore: Add some minor delay to avoid Amavis failing to connect
* tests(refactor): Make test cases for opendkim keysizes DRY
- These all do roughly the same logic that can be split into two separate methods.
- `_should_generate_dkim_key()` covers a bit more logic as it can be leveraged to handle other test cases that also perform the same logic.
- The `config/opendkim/` doesn't seem necessary for tests. Only the first few test cases here are testing against it, so we can conditionally make that available. `process_check_restart.bats` also depended on it to run OpenDKIM successfully, but this was due to the `setup-stack.sh` config defaults failing to find an "empty" file forcing `supervisord` to constantly restart the process..
- With this, there we inverse the default opendkim config, so we don't have to mount unique / empty subfolders for each test case, followed by copying over the two extra configs.
* tests(refactor): DRY up more test cases
All the remaining test cases but the last one were refactored here for a clean commit diff. The last test case will be refactored in the following commit.
Plenty of repeated logic spread across these test cases, now condensed into shared methods.
* tests(refactor): Make final test case DRY
* chore: Migrate to new testing helpers
* chore: Revise test case descriptions
* tests(refactor): Improve and simplify assertions
* tests(refactor): Use common container setup instead of `docker run`
- As the majority of test cases are only running `open-dkim` helper, we don't actually have to wait for a full container setup. So an alternative container start is called.
- Also improves assertions a bit more instead of just counting lines.
- Some test cases don't bind mount all of `/tmp/docker-mailserver` contents, thus don't raise permission errors on subsequent test runs.
- Instead of `rm -f` on some config files, have opted to mount them read-only instead, or alternatively mount an anonymous empty volume instead.
- Collapsed the first three test cases into one, thus no `setup_file()` necessary.
- Shift the `_wait_for_finished_setup_in_container()` method into `_common_container_setup()` instead since nothing else is using `_common_container_start()` yet, this allows for avoiding the wait.
* tests(refactor): Collapse dkim key size test cases into single test case
This makes these tests a bit more DRY, and enhances the raised quality issue with these tests. Now not only is the domain checked in the generated DNS dkim record, but we also verify the key size is corrected in the public and private keys via openssl.
* chore: Revise container names
* chore: Swap order of test case 1 and 2
* tests(refactor): Assert generated log output
- `__should_have_tables_trustedhosts_for_domain` shifted in each test case to just after generating the domains keys.
- Asserts `open-dkim` logs instead of just counting them.
- Added checks for domains that should not be present in a test case.
- Additional coverage and notes about the alias from vhost `@localdomain.com`
- Single assert statement with switch statement as all are using common args.
* chore: Minor changes
* tests(refactor): Share `find` logic in helpers and tests
* tests(fix): Listing file content does not need to match line order
The order printed from local system vs CI differed causing the CI to fail. The order of lines is irrelevant so `--index` is not required.
Additionally correct the prefix of the called method to be only one `_` now that it's a `common.bash` helper method.
* chore: Collapse custom DKIM selector test into custom DKIM domain test
These cover the same test logic for the most part, the first domain could also be testing the custom selector.
`special_use_folders.bats` + `mailbox_format_dbox` can assert lines instead, removing the need for `--partial`.

* chore: Extract out accounts test cases from `tests.bats`
Standard test file format, the test cases have been copied over unmodified.
* chore: Revise test case descriptions
* tests(refactor): `accounts.bats`
Revised test cases:
- Some common test case logic extracted to test methods.
- Update direct user management commands to use the `setup email ...` variants.
- Improved assertions.
- Removed `sleep 2` lines as the need for that is ambiguous (may no longer be relevant?)
- Additional commentary for maintaining
- Two test cases for missing `postfix-accounts.cf` opted to just run the image without any volumes instead, as the `without-accounts/` folder was empty anyway. 2nd test case can instead use a single `docker run` to check the newly created`postfix-accounts.cf` content.
- `test/config/without-accounts/` remains as `open_dkim.bats` presently uses it.
* chore: Remove unnecessary account removal assert
Traced this back to the original PR where it appears to have been a typo and was probably intended as a cleanup on the `user4` account. Not necessary, removing.
* chore: Rename `accounts.bat` -> `account_management.bats`

* tests: Migrate and combine ENV tests for `*_INET_PROTOCOLS`
These two features + tests were introduced years apart but serve the same purpose for both Postfix and Dovecot.
Using `--openssl` uses the native `openssl` package within the image instead of the older `1.0.2` bundled from `testssl.sh`.
The test is only testing cipher suite compatibility is what we expect it to be, thus we do not need to run `testssl.sh` with a broader range of ciphers.
* add functionality for filtering mail log by ID
This was not planned, but as @polarthene mentioned in
https://github.com/docker-mailserver/docker-mailserver/pull/3033#issuecomment-1407169569
, filtering the mail log by email ID would be (the only) correct
approach for the Rspamd test (to eliminate race conditions).
I asserted the currect state, and came to the conclusion that this might
(or actually is) something we want in more than one place. So I went
ahead and implemented a solution.
The solution for acquiring the ID is a bit slower because it ensures the
mail queue is empty _before_ and _after_ the mail is sent. This is the
tradeoff one has to make if they want to send multiple emails in one
test file and get their IDs.
I hope you like this approach. I will provide another PR that adjusts
our current tests to use these new functions.
* added note about our helper functions in the docs
I think our work for our custom test framework should be noted in the
docs for newcomers to better understand what they should do.
* adjust Rspamd test to use new helpers for sending
* improve filter helpers further
* add sanity check when acquiring mail ID
* re-add `refute_output` to test which should now work well
This doesn't make any difference to the tests performed here (_partly due to `--preference`_).
It would make a difference if performing a test for receiving a grade, which would otherwise fail due to chain of trust not being verifiable for a self-signed certificate (_or a signed certificate without a CA public key to verify against_)
* chore: Use a common method to check domain and fqdn config
* chore: Shift other test cases into shared test methods
* chore: Add another shared method for checking mail headers
* chore: Add another shared method for checking hostname
* refactor: Improve quality of shared test methods
Based on changes from an earlier closed hostname PR from Oct 2021 with additional revision to use `assert_output` and more thorough checking of values expected in output.
* chore: Move clean shutdown test to `process-check-restart.bats`
This was originally a single test case in `tests.bats` intended for `supervisord` testing.
It seems at some point it got reassigned to a hostname override test container, and then migrated to separate test file for hostname override test by accident.
It now belongs in the correct place again, as hostname config should have nothing to do with a graceful shutdown?
* chore: Prepare for migrating to use `test/helper/setup.bash`
* chore: Rename containers and configured FQDN settings
* chore: Convert to using common container setup helpers
Wait for SMTP port is left at the end to avoid additional start-up delays.
* chore: Use `_run_in_container_bash` helper
* chore: Be more specific on matching mail headers
- I could do multiple container grep calls instead, but opted to match by lines in file. This better ensures values are being matched to the correct lines.
- Renamed the test case descriptions.
- Expanded test coverage of the 4th container as it represents another DNS config, while the 3rd is just the 4th container with the `SRS_DOMAINNAME` env added, no value in more coverage there.
* chore: Remove redundant test coverage in `tests.bats`
These checks are performed in `mail_hostname.bats` with better coverage.
* chore: Move each containers setup into it's own test-case instead
* chore: Re-arrange container name IDs
The original `fqdn-with-subdomain` is now `with-nis-domain` which is more accurate. A new test case will properly cover the default `--hostname` only config that is not a bare domain.
* chore: Re-arrange test cases to align with new ID ordering
This commit just shifts the test cases, no new changes to any content beyond that.
* chore: Add new test case for default config
* chore: Review feedback `_run_in_container_bash` to `_run_in_container`
Co-authored-by: Georg Lauterbach <44545919+georglauterbach@users.noreply.github.com>
* chore: Additional review feedback
- Fix a suggested change bug with quote wrapping an interpolated variable.
- Convert two other `_bash` methods that were missed from review.
- Apply the last two suggested changes from review.
* chore: `_exec_in_container_bash` to `_exec_in_container`
The `| head -n 1` can be dropped if we know for sure it's only one line, which is what we expect. Quotes can then be dropped too.

* tests(fix): `spam_junk_folder.bats` Wait on Amavis port to be ready
Postfix can potentially be ready before Amavis is. This caused test failures as mail was sent before Amavis was ready to process it.
Both test cases shared the same test logic, except for the expected location to deliver the spam to. Extracted into a shared test method, and moved the port conditions into there.
* tests(chore): `spam_junk_folder.bats` minor revisions
Test case descriptions, container names and test prefix are now more descriptive of what is under test here (an ENV for Amavis).
* tests(chore): Move Amavis bounce test into `spam_junk_folder.bats`
These two tests seem to be related to the same feature. Grouping them into a single test file instead.
* tests(refactor): Split shared method into smaller methods
Now it can be better shared with the bounce test case.
* tests(chore): Shift test cases to match their CONTAINER_NAME order
No changes to code, just cut + paste of the `CONTAINER3_NAME` test case to shift it to the last test case position.
* added options to toggle OpenDKIM & OpenDMARC
rspamd can provide DKIM signing and DMARC checking itself, so users
should be able to disable OpenDKIM & OpenDMARC. The default is left at
1, so users have to to opt-in when the want to disable the features.
* misc small enhancements
* adjusted start of rspamd
The order of starting redis + rspamd was reversed (now correct) and
rspamd now starts with the correct user.
* adjusted rspamd core configuration
The main configuration was revised. This includes AV configuration as
well as worker/proxy/controller configuration used to control the main
rspamd processes.
The configuration is not tested extensively, but well enough that I am
confident to go forward with it until we declare rspamd support as
stable.
* update & improve the documentation
* add tests
These are some initial tests which test the most basic functionality.
* tests(refactor): Improve consistency and documentation for test helpers (#3012)
* added `ALWAYS_RUN` target `Makefile` recipies (#3013)
This ensures the recipies are always run.

* chore: Co-locate process checking and process restart verification
Extract the test cases for checking a process is running and properly restarts from various test files into a single one:
Core (always running):
opendkim, opendmarc, master (postfix)
ENV dependent:
amavi (amavisd-new), clamd, dovecot, fail2ban-server (fail2ban), fetchmail, postgrey, postsrsd, saslauthd
These now run off a single container with the required ENV and call a common function (the revised version in parallel test cases).
* fix(saslauthd): Quote wrap supervisor config vars
`saslauth.conf` calls `-O` option for most commands defined with an ENV that may be empty/null. This would cause the process to silently fail / die.
This doesn't happen if quote wrapping the ENV, which calls `-O` with an empty string.
Not necessary, but since one of `postgrey` ENV were quote wrapped in `supervisor-app.conf`, I've also done the same there.
* fix(postsrsd): Change supervisor `autorestart` policy to `true`
The PR that introduced the config switched from `true` to `unexpected` without any context. That prevents restart working when the process is killed. Setting to `true` instead will correctly restart the service.
* chore: Remove disabled postgrey test file
`mail_with_postgrey_disabled_by_default.bats` only checked the migrated test cases, removed as no longer serving a purpose.
* tests(refactor): Make `_should_restart_when_killed()` more reliable
The previous version did not ensure that the last checks process was actually restarted, only that it was running.
It turns out that `pkill` is only sending the signal, there can be some delay before the original process is actually killed and restarted.
This can be identified with `pgrep --older <seconds>`. First ensure the process is at a specified age, then after killing check that the process is not running that is at least that old, finally check that there is a younger process actually running.. (_could fail if a process doesn't restart, or there is a delay such as imposed by `sleep` in wrapper scripts for postfix and fail2ban_)
The helper method is not used anywhere else now, move it into this test instead. It has been refactored to accomodate the needs for `--older`, and `--list-full` provides some output that can be matched (similar for `pkill --echo`).
* test(docs): Add inline notes about processes
* chore: Compress test cases into single case with loop
Moves the list of processes into array vars to iterate through instead.
If a failure occurs, the process name is visible along with line number in `_should_restart_when_killed()` to identify what went wrong.
* chore: Handle `FETCHMAIL_PARALLEL=1` process checks as well
* tests: Add test case for disabled ENV
Additional coverage to match what other test files were doing before, ensuring that these ENV can prevent their respective service from running.
* chore: Move `clamd` enabled check to it's own test case
Not sure about this.
It reduces the time of CPU activity (sustained full load on a thread) and increase in memory usage (1GB+ loading signatures database), but as a separate test case it also adds 10 seconds without reducing the time of the test case it was extracted from.
* chore: Make `disabled` variant the 1st test case
* fix: Adjust test cases to pass when using slower wrapper scripts
* tests(refactor): `mail_fetchmail.bats` updated to new format
Additionally merges in the parallel test file.
* chore: Move `config/fetchmail.cf` into separate sub-directory
Keep out of the default base config for tests.
* chore: Change `fetchmail.cf` FQDNs to `.test` TLD
Changed the first configs remote and local user values to more clearly document what their values should represent (_and that they don't need to be a full mail address, that's just what our Dovecot is configured with for login_).
Shifted the `here` to the end of the `is` line. It's optional syntax, only intended to contrast with the remote `there` for readability.
Additionally configured imap protocol. Not tested or verified if that's correct configuration for usage with imap protocol instead. The fetchmail feature tests are currently lacking.
Added an inline doc into the fetchmail test to reference a PR about the importance of the trailing `.` in the config. Updated the partial matching to ensure it matches for that in the value as well.
* chore: Finalize `process-check-restart.bats`
Few minor adjustments. The other ENV for clamd doesn't seem to provide any benefit, trim out the noise. Added a note about why it's been split out.
Fetchmail parallel configs are matching the config file path in the process command that is returned. The `.rc` suffix is just to add further clarity to that.
* tests(refactor): `mail_changedetector.bats` - Leverage DRY methods
`supervisorctl tail` is not the most reliably way to get logs for the latest change detection and has been known to be fragile in the past.
We can instead read the full log for the service directly with `tac` and `sed` to extract all log content since the last change detection.
Common asserts have also been extracted out into separate methods.
* tests(chore): Remove sleep and redundant change event
Container 1 is still blocked at this point from an existing lock and change event.
Make the lock stale immediately and no extra sleep is required when paired with the helper method to wait until the event is processed (which should remove the stale lock).
* tests(refactor): Add more DRY methods
- Simplify the test case so it's easier to grok.
- 2nd test case (blocking) extracts out initial setup into a separate method and merges the later service restart logic which is redundant.
- Additional comments for improved context of what is going on / expected.
* tests(chore): Revise the change detection helper method
- Add explicit counting arg to change detection support.
- Extract revised logic into it's own generic helper method.
- Utilize this for a separate method that monitors for a change event having started, but not waiting for completion.
This allows dropping the 40 sec of remaining `sleep` in `mail_changedetector` test. It was also required due to potentially missing the timing of a change event completing concurrently in a 2nd container that needed to be waited on and then checked.
* tests(chore): Migrate to current test conventions
- Switch to common container setup helpers
- Update container name and change usage to variables instead.
- Adopt the new convention of prefix variable for test cases (revised test case descriptions).
* tests(chore): Remove legacy change detection
This has since been replaced with the new helper watches the `changedetector` service logs directly instead of only detecting a change has occurred via checksum comparison.
No tests use this method anymore, it was originally for `tests.bats`. Thus the tests in `test_helper.bats` are being dropped too. The new helper has test coverage in `changedetector` tests.
* chore: Lock removal should not incur `sleep 5` afterwards
- A new lock should be created by this script after removal. The sleep doesn't help avoid a race condition with lock file creation after removal.
- Reduces test time as a bonus.
- Added some additional comments to test.
* tests(chore): `tls_letsencrypt.bats` leverage improved change detection
- No need to wait on the change detection service anymore during container startup.
- No need to count change events processed either as waiting a fixed duration is no longer relied on.
- This makes the reload count method redundant, dropped.
* tests(chore): Convert `setup-cli.bats` to new test conventions
This test file was already adapted to the original common setup helpers.
- `TEST_NAME` replaced with `CONTAINER_NAME`.
- Prefix var added, test case descriptions drop explicit prefix.
- No other changes.
* tests(chore): Extract out helpers related to change-detection
- New helper file for sharing these helpers to tests.
- Includes the helpful log method from changedetector tests.
- No longer need to maintain duplicate copies of these methods during the test migration. All tests that use them are now importing the separate helper file.
- `tls_letsencrypt.bats` has switched to using the log helper.
- Generic log count helper is removed from `test_helper/common.bash` as any test that needs it in future can adapt to `helper/common.bash`.
* tests(refactor): `tls_letsencrypt.bats` remove `_get_service_logs()`
This helper does not seem useful as moving away from `supervisorctl tail` and no other tests had a need for it.
* tests(chore): Remove common setup methods from `test_helper/common.bash`
No other tests depend on this. Future tests will adopt the revised versions from `helper/setup.bash`.
Additionally updates `helper/setup.bash` comments that are no longer applicable to `TEST_TMP_CONFIG` and `CONTAINER_NAME`.
* chore: Use `|| true` to simplify setting `EXPECTED_COUNT` correctly
* chore: Drop ENV `ENABLE_POSTFIX_VIRTUAL_TRANSPORT`
* tests(chore): Remove redundant `dovecot-lmtp` config
None of this is needed. Only relevant change is changing the LMTP service listener for Dovecot and that can be delegated to `user-patches.sh`.
* tests(refactor): Use `user-patches.sh` instead of replacing config file
The only relevant changes in `test/config/dovecot-lmtp` regarding LMTP was:
- `/etc/dovecot/dovecot.conf` (`protocols = imap lmtp`) and `/etc/dovecot/protocols.d/` (`protocols = $protocols lmtp`).
- `conf.d/10-master.conf` only changed the LMTP service listener from a unix socket to TCP on port 24 (_this was the only change required for the test to pass_).
None of those configs are required as:
- `protocols = imap pop3 lmtp` [is the upstream default](https://doc.dovecot.org/settings/core/#core_setting-protocols), no need to add `lmtp`.
- The LMTP service listener is now configured for the test with `user-patches.sh`.
* tests(refactor): `mail_lmtp_ip.bats`
- Converted to new testing conventions and common container helpers.
- `ENABLE_POSTFIX_VIRTUAL_TRANSPORT` was not relevant, dropped.
- Revised test cases, logic remains the same.
- Large custom config used was not documented and doesn't appear to serve any purpose. Simplified by replacing with a single modification with `user-patches.sh`.
- Added some additional comments for context of test and improvements that could be made.
* tests(chore): Adjust comments
The comment from `mail_hostname` provides no valid context, it was likely copied over from `tests.bats` in Oct 2020 by accident.
The email sent is just for testing, nothing relevant to LMTP.
---
Added additional comment for test to reference extra information from.
* tests(chore): Update similar log line matching
Extracts out the match pattern and formatting commands into separate vars (reduces horizontal scrolling), and includes extra docs about what the matched line should be expected to look like.
* chore: Remove `backup` target from Makefile
- The `backup` target is no longer serving any value to us. It was made redundant with changes added in Oct 2020.
- `clean` target inline docs revised.
- `.gitignore` remove test lines that are no longer valid.
* chore: Parallel test target split to multi-line
* tests(fix): Test `setup.sh` with temporary config dir
The `no_containers.bats` test has many redundant test cases already covered by `setup-cli`. They're basically identical. Removed all but one.
This removes some config dirs that were being explicitly created instead of using the test helper to generate a directory that can be used to test the `-p` option instead.
* ci: Ensure tests are run when `Makefile` is modified
* fix: Workaround `postconf` write settle logic
After updating `main.cf`, to avoid an enforced delay from reading the config by postfix tools, we can ensure the modified time is at least 2 seconds in the past as a workaround. This should be ok with our usage AFAIK.
Shaves off 2+ seconds roughly off each container startup, reduces roughly 2+ minutes off tests.
* chore: Only modify `mtime` if less than 2 seconds ago
- Slight improvement by avoiding unnecessary writes with a conditional check on the util method.
- Can more comfortably call this during `postfix reload` in the change detection cycle now.
- Identified other tests that'd benefit from this, created a helper method to call instead of copy/paste.
- The `setup email restrict` command also did a modification and reload. Added util method here too.
* tests(fix): `mail_smtponly.bats` should wait for Postfix
- `postfix reload` fails if the service is not ready yet.
- `service postfix reload` and `/etc/init.d/postfix reload` presumably wait until it is ready? (as these work regardless)
* chore: Review feedback - Move reload method into utilities
* tests(chore): `tls-dh-params.bats` - Drop `ONE_DIR` ENV variants
There is no longer special handling for this ENV with this feature, these variant test cases serve no value.
* tests(refactor): `tls-dh-params.bats`
Converted to new common setup helper methods and testing structure.
No `setup_file` needed. Only two test cases used now, the Mozilla check is bundled into the default params test case where it's relevant.
Refactored some logic into common functions. Should be easier to grok intention.
* chore: Apply review feedback
Co-authored-by: Casper <casperklein@users.noreply.github.com>
* chore: Inline functions into test cases
As per review feedback
While working on tests, I noticed that some of the configs being mounted were adding a few seconds to the start-up time of each container. Notably `postfix-*` and `dovecot.conf` config files, which have been extracted out into their own tests with those files moved into a separate config folder.
`tests.bats` has been adapted to the common setup helper, and removed ENV no longer required to run those tests. Future PRs will extract out more tests.
Review may be easier via individual commit diffs and their associated commit messages describing relevant changes.

```markdown
tests(chore): `tests.bats` - Remove redundant config
===
- ONEDIR volume support no longer relevant, this should have been dropped.
- ClamAV ENV no longer relevant as related tests have been extracted already.
- Same with the some of the SpamAssassin ENV config.
- `VIRUSMAILS_DELETE_DELAY` is tested in the file, but doesn't use this ENV at all? (runs a separate instance to test the ENV instead)
- Hostname updated in preparation for migrating to new test helpers. Relevant test lines referencing the hostname have likewise been updated.
```
```markdown
tests(chore): `tests.bats` - Convert to common setup
===
ENV remains the same, but required adding `ENABLE_AMAVIS=1` to bring that back, while the following became redundant as they're now defaulting to explicitly disabled in the helper method:
- `ENABLE_CLAMAV=0`
- `LOG_LEVEL=debug`
- `ENABLE_UPDATE_CHECK=0`
- `--hostname` + `--tty` + standard `--volume` lines
- `-e` option expanded to long-name `--env`, and all `\` dropped as no longer necessary.
`wait_for_finished_setup_in_container` is now redundant thanks to `common_container_setup`.
```
```markdown
tests(refactor): `tests.bats` - Extract out Dovecot Sieve tests
===
Sieve test files relocated into `test/config/dovecot-sieve/` for better isolation.
`dovecot.sieve` was not using the `reject` import, and we should not encourage it? (docs still do):
https://support.tigertech.net/sieve#the-sieve-reject-jmp
```
```markdown
tests: `tests.bats` - Extract out `checking smtp` tests
===
Migrated to the standard template and copied over the original test cases with `_run_in_container` adjustment only.
Identified minimum required ENV along with which mail is required for each test case.
```
```markdown
tests(refactor): `smtp-delivery.bats`
===
- Disabled `ENABLE_SRS=1`, not necessary for these tests.
- Added a SpamAssassin related test (X-SPAM headers) which requires `SA_TAG` to properly pass (or `ENABLE_SRS=1` to deliver into inbox).
- Many lines with double quotes changed to single quote wrapping, and moving out `grep` filters into `assert_output --partial` lines instead.
- Instead of `wc -l` making failures less helpful, switch to the helper method `_should_output_number_of_lines`
- x2 `assert_output` with different EOF style of usage was not actually failing on tests when it should. Changed to assert partial output of each expected line, and count the number of lines instead.
- Added additional comments related to the test cases with a `TODO` note about `SPAMASSASSIN_SPAM_TO_INBOX=1`.
- Revised test case names, including using the common prefix var.
- `tests.bats` no longer needs to send all these emails, no other test cases require them. This affects a test checking a `/mail` folder exists which has been corrected, and a quotas test case adjusted to expect an empty quota size output.
```
```markdown
tests: `tests.bats` - Extract out test cases for config overrides
===
Slight improvement by additionally matching `postconf` output to verify the setting is properly applied.
```
```markdown
tests: `tests.bats` - Extract out Amavis SpamAssassin test case
===
Removes the need for SpamAssassin ENV in `tests.bats`.
```
</details>
- `disabled_clamav_spamassassin`:
- Just shuffling the test order around, and removing the restart test at the end which doesn't make sense.
- `postscreen`:
- Now uses common helper for getting container IP
- Does not appear to need the `NET_ADMIN` capability?
- Reduced startup time for the 2nd container + additional context about it's relevance.
- Test cases are largely the same, but refactored the `nc` alternative that properly waits it's turn. This only needs to run once. Added additional commentary and made into a generic method if needed in other tests.
- `fail2ban`:
- Use the common container IP helper method.
- Postscreen isn't affecting this test, it's not required to do the much slower exchange with the mail server when sending a login failure.
- IP being passed into ENV is no longer necessary.
- `sleep 5` in the related test cases doesn't seem necessary, can better rely on polling with timeout.
- `sleep 10` for `setup.sh` also doesn't appear to be necessary.
- `postgrey`:
- Reduced POSTGREY_DELAY to 3, which shaves a fair amount of wasted time while still verifying the delay works.
- One of the checks in `main.cf` doesn't seem to need to know about the earlier spamhaus portion of the line to work, removed.
- Better test case descriptions.
- Improved log matching via standard method that better documents the expected triplet under test.
- Removed a redundant whitelist file and test that didn't seem to have any relevance. Added a TODO with additional notes about a concern with these tests.
- Reduced test time as 8 second timeouts from `-w 8` don't appear to be required, better to poll with grep instead.
- Replaced `wc -l` commands with a new method to assert expected line count, better enabling assertions on the actual output.
- `undef_spam_subject`:
- Split to two separate test cases, and initialize each container in their case instead of `setup_file()`, allowing for using the default `teardown()` method (and slight benefit if running in parallel).
- `permit_docker`:
- Not a parallel test, but I realized that the repeat helper methods don't necessarily play well with `run` as the command (can cause false positive of what was successful).
- The usual serial to parallel test conversion to utilize the `setup.bash` common setup structure, and adding a `TEST_PREFIX` var for each test case to leverage.
- Standardize on parallel test naming conventions for variables / values.
- More consistent use of `bash -c` instead of `/bin/bash -c` or `/bin/sh -c`.
- Using the `_run_in_container` helper instead of `run docker exec ${CONTAINER_NAME}`.
- Updates tests to use the `check_if_process_is_running` helper.
---
chore: Revise inline docs for the `ssl_letsencrypt` test
- Moves the override to be in closer proximity to the `initial_setup` call, and better communicates the intent to override.
- Removes top comment block that is no longer providing value or correct information to maintainers.
- Revised `acme.json` test case inline doc comments.
`tls.bash` helper was adapted to the new helper scripts location. The `setup.bash` helper saw a bugfix (expanding the array properly) and updates the container default config to configure for IPv4 explicitly.
The IPv4 default was added after recent Docker pushes and I saw weird IPv6 related errors in the logs.. now we're sure IPv4 is the default during tests.
Added functionality to check if a process is running:
- This change adds a helper function to check whether a program is running inside a container or not.
- This added the need for a function like `_run_in_container` but allowing for providing an explicit container name.
- Future PRs can use this helper function now to check whether a process is running or not. This was done for the tests of Fail2Ban, but can be used for other tests in the future as well.
---
chore: Restructured BATS flags in `Makefile`
The `Makefile` has seen a bit of a restructuring when it comes to flags:
1. The `MAKEFLAGS` variables is used by `make`, and allows for adding additional flags that can be used within in recursive calls (via `$(MAKE)`) too, thus DRY approach.
2. The flags for calling BATS were adjusted. `--no-parallelize-within-files` has been added as well to ensure tests _inside_ a single file are run sequentially.
`dms-test` prefix matching changed to expect a `_` suffix as a delimiter.
---
docs: Add a note regarding output from running tests in parallel
* chore: Set `TLS_INTERMEDIATE_SUITE` to only use TLS 1.2 ciphersuites
Removes support of the following cipher suites that are only valid for TLS 1.0 + 1.1:
- `ECDHE-ECDSA-AES128-SHA`
- `ECDHE-RSA-AES128-SHA`
- `ECDHE-ECDSA-AES256-SHA`
- `ECDHE-RSA-AES256-SHA`
- `DHE-RSA-AES128-SHA`
- `DHE-RSA-AES256-SHA`
* chore: Update TLS version min and ignore settings
These are now the same as modern settings.
* fix: Remove min TLS support workaround
No longer required now that outdated TLS versions have been dropped.
* tests: Remove support for TLS 1.0 and 1.1 ciphersuites
* tests: Remove support for TLS 1.0 and 1.1 ciphersuites (Port 25)
The removed SHA1 cipher suites are still supported in TLS 1.2, thus they've been excluded for port 25 via the `SHA1` exclusion pattern in `main.cf`.
With `reload` a change detection event during local testing can be processed in less than a second according to logs. Previously this was 5+ seconds (_plus additional downtime for Postfix/Dovecot to become available again_).
In the past it was apparently an issue to use `<service> reload` due to a concern with the PID for wrapper scripts that `supervisorctl` managed, thus `supervisorctl <service> restart` had been used. Past discussions with maintainers suggest this is not likely an issue anymore, and `reload` should be fine to switch to now 👍
---
**NOTE:** It may not be an issue in the CI, but on _**local systems running tests may risk failure in `setup-cli.bats` from a false positive**_ due to 1 second polling window of the test helper method, and a change event being possible to occur entirely between the two checks undetected by the current approach.
If this is a problem, we may need to think of a better way to catch the change. The `letsencrypt` test counts how many change events are expected to have been processed, and this could technically be leveraged by the test helper too.
---
**NOTE:** These two lines (_with regex pattern for postfix_) are output in the terminal when using the services respective `reload` commands:
```
postfix/master.*: reload -- version .*, configuration /etc/postfix
dovecot: master: Warning: SIGHUP received - reloading configuration
```
I wasn't sure how to match them as they did not appear in the `changedetector` log (_**EDIT:** they appear in the main log output, eg `docker logs <container name>`_).
Instead I've just monitored the `changedetector` log messages, which should be ok for logic that previously needed to ensure Dovecot / Postfix was back up after the `restart` was issued.
---
Commit history:
* chore: Change events `reload` Dovecot and Postfix instead of `restart`
Reloading is faster than restarting the processes.
Restarting is a bit heavy handed here and may no longer be necessary for general usage?
* tests: Adapt tests to support service `reload` instead of `restart`
* chore: Additional logging for debugging change event logs
* fix: Wait on change detection, then verify directory created
Change detection is too fast now (0-1 seconds vs 5+).
Directory being waited on here was created near the end of a change event, reducing that time to detect a change by the utility method further.
We can instead check that the directory exists after the change detection event is completed.
* chore: Keep using the maildir polling check
We don't presently use remote storage in tests, but it might be relevant in future when testing NFS.
This at least avoids any confusing failure happening when that scenario is tested.
As per deprecation notice from v11.3 release notes, and a related prior PR; this ENV is to be removed.
It's no longer considered useful, and none of the tests that configured it were actually using it for relaying anything.
- Introduced `CONTAINER_NAME` and `TEST_NAME_PREFIX` as new vars for better managing test consistency (DRY).
- `CONTAINER_NAME` replaces any repeated container name with the variable. The value will differ slightly as the prior prefix (`mail_`) has been changed to `dms-test-`.
- `TEST_NAME_PREFIX` provides a prefix value for each `@test` description string.
---
chore: Add a reference template for tests
The current `test/test_helper/common.bash` was getting large. Setup logic has been extracted out into a new file.
`common.bash` resides in a directory named `test_helper/`, the `test_` prefix is redundant.
As an interim solution this provides a new approach for the updated tests, while the "old" tests can use the "old" `common.bash`. Eventually all tests should migrate to the new approach in `helper/` instead of the older `test_helper/`.
The new helper files are located under `test/helper/` (_which drops the `test_` prefix_). The new and updated helpers apply the new naming convention for ENV variables (_such as `CONTAINER_NAME` or `IMAGE_NAME`_).
---
Some refactoring occurred, including new methods like `_run_in_container()` and `_default_teardown()`.
---
I encountered a situation before in which the updated tests would fail because there were collisions of ENV names in the tests (_for example with `CONTAINER_NAME`_).
Allows for using `load` with an absolute path instead of a relative one, which makes it possible to group tests into different directories.
Parallel tests differ slightly, loading the newer `helper/common.bash` and `helper/setup.bash` files instead of the older `test_helper/common.bash` which serial tests continue to use.
- `test_helper.bats` needs more work than this PR provides to be compatible with parallel tests, so must remain as a serial test for now.
- `spam_bounced.bats` had failures as a serial test, but works well converted to a parallel test in a future commit.
Currently a change detection would be triggered and during processing, a CRLF is converted to LF, which updates the `postfix-accounts.cf` file and triggers another change event.
No need for the first approach to add an account, and it is the culprit for causing the CRLF to appear.
This new script is a clean way of handling the installation of packages.
I think the huge `RUN` command in `Dockerfile` was hard to read and
maintain.
Using a script is a non-issue, as the image is rebuilt whenever the
script is touched.

* tests: Ensure excessive FD limits are avoided
Processes that run as daemons (`postsrsd` and `fail2ban-server`) initialize by closing all FDs (File Descriptors).
This behaviour queries that maximum limit and iterates through the entire range even if only a few FDs are open. In some environments (Docker, limit configured by distro) this can be a range exceeding 1 billion (from kernel default of 1024 soft, 4096 hard), causing an 8 minute delay with heavy CPU activity.
`postsrsd` has since been updated to use `close_range()` syscall, and `fail2ban` will now iterate through `/proc/self/fd` (open FDs) which should resolve the performance hit. Until those updates reach our Docker image, we need to workaround it with `--ulimit` option.
NOTE: If `docker.service` on a distro sets `LimitNOFILE=` to approx 1 million or lower, it should not be an issue. On distros such as Fedora 36, it is `LimitNOFILE=infinity` (approx 1 billion) that causes excessive delays.
* chore: Use Docker host limits instead
Typically on modern distros with systemd, this should equate to 1024 (soft) and 512K (hard) limits. A distro may override the built-in global defaults systemd sets via setting `DefaultLimitNOFILE=` in `/etc/systemd/user.conf` and `/etc/systemd/system.conf`.
* tests(fix): Better prevent non-deterministic failures
- `no_containers.bats` tests the external script `setup.sh` (without `-c`). It's expected that no existing DMS container is running - otherwise it may attempt to use that container and fail. Detect this and fail early via `setup_file()` step.
- `mail_hostname.bats` had a odd timing failure with teardown due to the last tests bringing the containers down earlier (`docker stop` paired with the `docker run --rm`). Adding a moment of delay via `sleep` helps avoid that false positive scenario.
## Quick Summary
Resolves a `TODO` task with `addmailuser`.
## Overview
The main change is adding three new methods in `common.bash`, which replace the completion delay in `addmailuser` / `setup email add` command.
Other than that:
- I swapped `sh -c 'addmailuser ...'` to `setup email add ...`.
- Improved three tests in `setup-cli.bats` for `setup email add|update|del` (_logic remains effectively the same still_).
- Rewrote the `TODO` comment for `setup-cli.bats` test on `setup email del` to better clarify the concern, but the test itself was no longer affected due to changes prior to this PR, so I enabled the commented out assertion.
- Removed unnecessary waits. The two `skip` tests in `test/tests.bats` could be enabled again after this PR.
- Additional fixes to tests were made during the PR (see discussion comments for details), resolving race conditions.
Individual commit messages of the PR provide additional details if helpful.

## Relevant commit messages
* chore: Remove creation delay in `addmailuser`
This was apparently only for supporting tests that need to wait on account creation being ready to test against.
As per the removed inline docs, it should be fine to remove once tests are updated to work correctly without it.
* tests(feat): Add two new common helper methods
`wait_until_account_maildir_exists()` provides the same logic `addmailuser` command was carrying, to wait upon the account dir creation in `/var/mail`.
As this was specifically to support tests, it makes more sense as a test method.
`add_mail_account_then_wait_until_ready()` was added to handle the common pattern of creating account and waiting on it. An internal assert will ensure the account was successfully created first during the test before attempting to wait.
* tests(feat): Add common helper for waiting on change event to be processed
The current helper is more complicated for no real benefit, it only detects when a change is made that would trigger a change event in the `changedetector` service. Our usage of this in tests however is only interested in waiting out the completion of the change event.
Remove unnecessary change event waits. These waits should not be necessary if handled correctly.
* tests: `addmailuser` to `add_mail_account_then_wait_until_ready mail()`
This helper method is used where appropriate.
- A password is not relevant (optional).
- We need to wait on the creation on the account (Dovecot and `/var/mail` directory).
* tests: `setup-cli` revise `add`, `update`, `del` tests
The delete test was failing as the `/var/mail` directory did not yet exist.
There is now a proper delay imposed in the `add` test now shares the same account for both `update` and `del` tests resolving that failure.
Additionally tests use better asserts where appropriate and the wait + sleep logic in `add` has been improved (now takes 10 seconds to complete, approx half the time than before).
The `del` test TODO while not technically addressed is no longer relevant due to the tests being switched to `-c` option (there is a separate `no container` test file, but it doesn't provide a `del` test).
* tests(fix): Ensure Postfix is reachable after waiting on ClamAV
There is not much reason to check before waiting on ClamAV.
It is more helpful to debug failures from `nc` mail send commands if we know that nothing went wrong inbetween the ClamAV wait time.
Additionally added an assertion which should provide more information if this part of the test setup fails again.
* tests(fix): Move health check to the top
This test is a bit fragile. It relies on defaults for the healthcheck with intervals of 30 seconds.
If the check occurs while Postfix is down due a change event from earlier tests and the healthcheck kicks in at that point, then if there is not enough time to refresh the health status from `unhealthy`, the test will fail with a false-positive as Postfix is actually working and up again..
* tests(fix): Wait on directory to be removed
Workaround that tries not to introduce heavier delays by waiting on a full change event to complete in the previous `email update` if possible.
There is a chance that the account has the folder deleted, but restored from an active change event (for password update, then the account delete).
The new version uses our `log.sh` helper to simplify logging
significantly. Moreover, the script was adjusted to the current style
and the GitHub workflow was streamlined. The workflow is ot providing
the version anymore (which was useless anyway), and has been compacted.
* outsourcing env variable setup
This commit contains major parts of the work of refactoring the setup
and usage of environment variables. It outsources the setup into its own
script and provides dedicated functions to be executed at a later point in time.
A **new** env variable was added: `USER_PROVISIONG` which provides a
better way of defining which method / protocol to use when it comes to
setting up users. This way, the `ENABLE_LDAP` variable is deprecated,
but all of this is backwards compatible due to a "compatibility layer", a function provided by the new variables script.
This is not a breaking change. It mostly refators internal scripts. The
only change facing the user-side is the deprecation of `ENABLE_LDAP`. We
can prolong the period of deprecation for this variable as long as we
want, because the new function that ensures backwards compatibility
provides a clean interface for the future.

* tests: Update testing submodules (bats-assert, bats-support)
These two submodules were migrated to the `bats-core` organization, where they continued to receive updates.
* tests: Use tagged release of `bats-core/bats-support`
This is technically one commit backwards, but no relevant difference has been made since, other than moving the submodule to the `bats-core` organization.
* tests: Bump `bats-assert` to August 2022 (master)
No official release tag since Nov 2018, but a fair amount of changes since then.
* tests: Bump `bats-core` to `v1.7.0` release
* tests(fix): Correctly use assertions
Some tests were updated as the upgrade of bats submodules had `assert` methods raise awareness of incorrect usage.
This additionally revealed some existing tests that weren't meant to be using `run`, which swallowed failures from surfacing.
See the associated PR for more detailed commentary on specific changes.
### Commands refactored:
- User (**All:** add / list / update / del + _dovecot-master variants_)
- Quota (**All:** set / del)
- Virtual Alias (**All:** add / list /del)
- Relay (**All:** add-relayhost / add-sasl / exclude-domain)
### Overall changes involve:
- **Fairly common structure:**
- `_main` method at the top provides an overview of logical steps:
- After all methods are declared beneath it (_and imported from the new `helpers/database/db.sh`_), the `_main` is called at the bottom of the file.
- `delmailuser` additionally processes option support for `-y` prior to calling `_main`.
- `__usage` is now consistent with each of these commands, along with the `help` command.
- Most logic delegated to new helper scripts. Some duplicate content remains on the basis that it's low-risk to maintenance and avoids less hassle to jump between files to check a single line, usually this is arg validation.
- Error handling should be more consistent, along with var names (_no more `USER`/`EMAIL`/`FULL_EMAIL` to refer to the same expected value_).
- **Three new management scripts** (in `helpers/database/manage/`) using a common structure for managing changes to their respective "Database" config file.
- `postfix-accounts.sh` unified not only add and update commands, but also all the dovecot-master versions, a single password call for all 4 of them, with a 5th consumer of the password prompt from the relay command `addsaslpassword`.
- These scripts delegate actual writes to `helpers/database/db.sh` which provides a common API to support the changes made.
- This is more verbose/complex vs the current inline operations each command currently has, as it provides generic support instead of slightly different variations being maintained, along with handling some edge cases that existed and would lead to bugs (notably substring matches).
- Centralizing changes here seems wiser than scattered about. I've tried to make it easy to grok, hopefully it's not worse than the current situation.
- List operations were kept in their respective commands, `db.sh` is only really managing writes. I didn't see a nice way for removing the code duplication for list commands as the duplication was fairly minimal, especially for `listalias` and `listdovecotmasteruser` which were quite simple in their differences in the loop body.
- `listmailuser` and `delmailuser` also retain methods exclusive to respective commands, I wasn't sure if there was any benefit to move those, but they were refactored.
* chore: Create bare new test file `setup-cli.bats`
Bare minimum to setup a new test.
* chore: Transfer over relevant tests
* chore: `mail` container name to dynamic `${TEST_NAME}`
Only applied where it's relevant. Next commit will handle the config path correction.
* chore: Use `TEST_TMP_CONFIG` for referencing local config directory
Could technically use the existing function call. Some paths were using a hard-coded config location.
Both have been converted to `TEST_TMP_CONFIG` and related `grep` calls normalizing the quote mark usage, escaping doesn't seem necessary.
* tests(fix): Create container without providing extra args reference var
If a variable name (of an array) was not provided to reference, this would fail trying to reference `'`.
* 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.
* chore: Fix typo
* chore: Apply explicit chroot default for `sender-cleanup`
The implicit default is set to `y` as a compatibility fallback, but otherwise it is [advised to set to `n` going forward](http://www.postfix.org/COMPATIBILITY_README.html#chroot).
Test was changed to catch any backwards-compatibility logs, not just those for `chroot=y`. `using` added as a prefix to avoid catching log message whenever a setting is changed that the default compatibility level is active.
* chore: Set `compatibility_level` in `main.cf`
We retain the level`2` value previously set via scripts. This avoids log noise that isn't helpful.
Applied review feedback to give maintainers some context with this setting and why we have it presently set to `2`.
* chore: Extract change-detection method to it's own helper
This doesn't really belong in `helpers/ssl.sh`. Moving to it's own helper script.
* chore: Co-locate related change-detection method from container startup
It seems relevant to migrate the related support during startup for the change detection feature into this helper.
I opted to move the call from `start-mailserver.sh` into the `_setup` call at the end for a more explicit/visible location.
* chore: Move `CHKSUM_FILE` into `helpers/change-detection.sh`
It belongs there, not in `helpers/index.sh`.
* chore: Revise inline documentation
* tests(fix): Ensure correct functionality
Presently `test/test_helper.bats` is using it's own `CHKSUM_FILE` instead of sourcing the var for the filepath.
`test_helper/common.bash` was calling a method to check for changes, but this helper may not correctly detect letsencrypt related changes as these are not ENV rely on, but global vars handled by `helpers/dns.sh`, so that should be run first like it is for `check-for-changes.sh`.
* tests(chore): Use `CHKSUM_FILE` var from helper
* chore: `addmailuser` should use `CHKSUM_FILE` var
* chore: Update `check-for-changes.sh` log message with correct path
* 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.
Dovecot master accounts can now be configured in DMS via `setup.sh`.
A master account is useful for administration purposes, or to perform mailbox backups of every user account over IMAP.

* chore: Extract letsencrypt logic into methods
This allows other scripts to share the functionality to discover the correct letsencrypt folder from the 3 possible locations (where specific order is important).
As these methods should now return a string value, the `return 1` after a panic is now dropped.
* chore: Update comments
The todo is resolved with this PR, `_setup_ssl` will be called by both cert conditional statements with purpose for each better documented to maintainers at the start of the logic block.
* refactor: Defer most logic to helper/ssl.sh
The loop is no longer required, extraction is delegated to `_setup_ssl` now.
For the change event prevention, we retrieve the relevant FQDN via the new helper method, beyond that it's just indentation diff.
`check-for-changes.sh` adjusted to allow locally scoped var declarations by wrapping a function. Presently no loop control flow is needed so this seems fine. Made it clear that `CHANGED` is local and `CHKSUM_FILE` is not.
Panic scope doesn't require `SSL_TYPE` for context, it's clearly`letsencrypt`.
* fix: Correctly match wildcard results
Now that the service configs are properly updated, when the services restart they will return a cert with the SAN `DNS:*.example.test`, which is valid for `mail.example.test`, however the test function did not properly account for this in the regexp query.
Resolved by truncating the left-most DNS label from FQDN and adding a third check to match a returned wildcard DNS result.
Extracted out the common logic to create the regexp query and renamed the methods to communicate more clearly that they check the FQDN is supported, not necessarily explicitly listed by the cert.
* tests(letsencrypt): Enable remaining tests
These will now pass. Adjusted comments accordingly.
Added an additional test on a fake FQDN that should still be valid to a wildcard cert (SNI validation in a proper setup would reject the connection afterwards).

* first adjustments to use Fail2Ban with nftables
* replace `iptables` -> `nftables` and adjust tests
nftables lists IPs a bit differently , so the order was adjusted for the
tests to be more flexible.
* line correction in mailserver.env
* change from `.conf` -> `.local` and remove redundant config
* revert HEREDOC to `echo`
Co-authored-by: Casper <casperklein@users.noreply.github.com>
* refactored `check-for-changes.sh`
I refactored `check-for-changes.sh` and used the new log. `_notify` can
therefore be deleted as it is used no more.
I opted to source `/etc/dms-settings` as a whole to
future-proof the script. When the DNS adjustments PRs (that do not exist
by now but will exit in the future) are done, we can then remove
`_obtain_hostname_and_domainname` because we're already writing the
variables to `/etc/dms-settings`. I left instructions in the script in
the form of TODO comments.
Because we now log the date for all messages of the changedetector, we
need to `tail` a bit more log than before.
* disabled unreliable test
The "quota exceeded" test is unreliable and failed too often lately for
my taste. Therefore, I'd like to disable it because there is no use in
having such a test.
* corrected PR id in URL
* refactored scripts located under `target/bin/`
The scripts under `target/bin/` now use the new log and I replaced some
`""` with `''` on the way. The functionality stays the same, this mostly
style and log.
* corrected fail2ban (script and tests)
* corrected OpenDKIM log output in tests
* reverted (some) changes to `sedfile`
Moreover, a few messages for BATS were streamlined and a regression in
the linting script reverted.
* apple PR feedback
* improve log output from `fail2ban` script
The new output has a single, clear message with the '[ ERROR ] '
prefix, and then output that explains the error afterwards. This is
coherent with the logging style which should be used while providing
more information than just a single line about IPTables not functioning.
* simplified `setquota` script
* consistently named the `__usage` function
Before, scripts located under `target/bin/` were using `usage` or
`__usage`. Now, they're using `__usage` as they should.
* improved `sedfile`
With `sedfile`, we cannot use the helper functions in a nice way because
it is used early in the Dockerfile at a stage where the helper scripts
are not yet copied. The script has been adjusted to be canonical with
all the other scripts under `target/bin/`.
* fixed tests
* removed `__usage` from places where it does not belong
`__usage` is to be used on wrong user input, not on other failures as
well. This was fixed in `delquota` and `setquota`.
* apply PR review feedback
* added new `_log` function
With `_log`, the `_notify` method wa rendered obsolete. `_notify` was
not completely removed due to test failures in `check-for-changes.sh`.
The new `_log` function properly uses log levels such as `trace`,
`debug`, `info`, `warn` and `error`. It provides a cleaner solution
and renders `DMS_DEBUG` obsolete too (as only `_notify` depends on it).
* converted all helper script to new `_log` function
* converted all startup stacks to new `log` function
* `start-mailserver.sh` now uses new `_log` function
* final test and misc small script adjustments
* updated documentation
The new setup will now set env variables on one place and on one place
only. The old setup used two separate places wich is not DRY and
confusing.
Some default values changed:
1. PFLOGSUMM_TRIGGER: logrotate => none
2. REPORT_SENDER: mailserver-report@HOSTNAME => mailserver-report@DOMAIN
3. REPORT_RECIPIENT: "0" => POSTMASTER_ADDRESS
One env variable was renamed: REPORT_INTERVAL => LOGROTATE_INTERVAL
I believe these defaults to be more sensible, especially the REPORT_RECIPIENT
address. The PFLOGSUMM_TRIGGER value was changed to `none` because otherwise
people would start getting daily Postfix log summary reports automatically.
Now, this is opt-in, and reports are sent only when enabled properly.
Some of the variables changed were marked as deprecated. I removed the note,
as the variables now bear some (sane) defaults again for other variables
(i.e.) REPORT_RECIPIENT is now default for other recipient addresses.
