test_rewrite_subject() is prone to failure when it checks for the delivered message, because fetch_all_messages() raises "ValueError: no messages in imap folder". The check has the potential to happen before the server has had a chance to deliver the message to the user's inbox. - Added a function try_n_times() that attempts to call a function the specified number of times, with a 1-second sleep between calls. The call is retried until it doesn't raise an exception. The last call is made without a 'try' block, so that the final exception passes through to the caller if it does not return. - Wrapped call to fetch_all_messages() in try_n_times(), with 5 attempts specified.

Revised test_deployed_state() to perform the same error-handling on Git commands that cmdeploy does. If 'git rev-parse' returns an error, the value "unknown" is used. If 'git diff' returns an error, the null string is used. - This fixes failures in environments where Git is not installed or where the .git subdirectory is not present (as long as the server was deployed in the same way). --- cmdeploy/src/cmdeploy/tests/online/test_1_basic.py | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) diff --git a/cmdeploy/src/cmdeploy/tests/online/test_1_basic.py b/cmdeploy/src/cmdeploy/tests/online/test_1_basic.py index 822b71f..28a4a51 100644 --- a/cmdeploy/src/cmdeploy/tests/online/test_1_basic.py +++ b/cmdeploy/src/cmdeploy/tests/online/test_1_basic.py @@ -223,8 +223,14 @@ def test_expunged(remote, chatmail_config): def test_deployed_state(remote): - git_hash = subprocess.check_output(["git", "rev-parse", "HEAD"]).decode() - git_diff = subprocess.check_output(["git", "diff"]).decode() + try: + git_hash = subprocess.check_output(["git", "rev-parse", "HEAD"]).decode() + except Exception: + git_hash = "unknown\n" + try: + git_diff = subprocess.check_output(["git", "diff"]).decode() + except Exception: + git_diff = "" git_status = [git_hash.strip()] for line in git_diff.splitlines(): git_status.append(line.strip().lower()) From f21e4ff55bee8049ddbfc36e8479ea001ced843d Mon Sep 17 00:00:00 2001 From: missytake Date: Wed, 15 Oct 2025 14:14:06 +0200 Subject: [PATCH 38/52] opendkim: increase DNSTimeout from 5 (default) to 60 fix #667 --- CHANGELOG.md | 3 +++ cmdeploy/src/cmdeploy/opendkim/opendkim.conf | 1 + 2 files changed, 4 insertions(+) diff --git a/CHANGELOG.md b/CHANGELOG.md index 3505485..e8f3a1c 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -17,6 +17,9 @@ - Ignore all RCPT TO: parameters ([#651](https://github.com/chatmail/relay/pull/651)) +- Increase opendkim DNS Timeout from 5 to 60 seconds + ([#672](https://github.com/chatmail/relay/pull/672)) + - Add config parameter for Let's Encrypt ACME email ([#663](https://github.com/chatmail/relay/pull/663)) diff --git a/cmdeploy/src/cmdeploy/opendkim/opendkim.conf b/cmdeploy/src/cmdeploy/opendkim/opendkim.conf index 2cc930e..188d69d 100644 --- a/cmdeploy/src/cmdeploy/opendkim/opendkim.conf +++ b/cmdeploy/src/cmdeploy/opendkim/opendkim.conf @@ -13,6 +13,7 @@ OversignHeaders From On-BadSignature reject On-KeyNotFound reject On-NoSignature reject +DNSTimeout 60 # Signing domain, selector, and key (required).
