From 504590c99d297ebd376d66c15e911dc785355d47 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Hallvard=20Nyg=C3=A5rd?= <168380+HNygard@users.noreply.github.com> Date: Sat, 31 Jan 2026 16:17:37 +0100 Subject: [PATCH 1/7] Replace Laminas Mail with Zbateson mail-mime-parser MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Why: Laminas Mail strictly enforces RFC compliance and throws exceptions when parsing emails with common real-world violations. Norwegian government email servers frequently send emails with: - Raw UTF-8 bytes in headers (e.g., 'Lødingen Kommune' in Received headers) - Charset mismatches (UTF-8 bytes declared as ISO-8859-1) - Malformed encoded-words (missing ?= delimiters) This required ~720 lines of workaround code to sanitize emails before Laminas could parse them. Zbateson handles all these cases natively, allowing us to delete the workarounds and simplify the email parsing architecture significantly. Changes: - Replace laminas/laminas-mail with zbateson/mail-mime-parser - Remove sanitization methods: fixCharsetMismatchInEncodedWords(), sanitizeNonAsciiInHeaderValue(), stripProblematicHeaders(), readLaminasMessage_withErrorHandling(), and debugging helpers - Simplify extractContentFromEmail() to use Zbateson's getTextContent() and getHtmlContent() which handle encoding automatically - Update tests for new parser behavior Co-Authored-By: Claude Opus 4.5 --- .../ThreadEmailExtractorEmailBody.php | 894 ++------------ organizer/src/class/Imap/ImapEmail.php | 24 +- organizer/src/composer.json | 2 +- organizer/src/composer.lock | 1060 ++++++++++------- .../ThreadEmailExtractorEmailBodyTest.php | 478 ++++---- .../Extraction/ZbatesonValidationTest.php | 414 +++++++ organizer/src/tests/Imap/ImapEmailTest.php | 24 +- 7 files changed, 1335 insertions(+), 1561 deletions(-) create mode 100644 organizer/src/tests/Extraction/ZbatesonValidationTest.php diff --git a/organizer/src/class/Extraction/ThreadEmailExtractorEmailBody.php b/organizer/src/class/Extraction/ThreadEmailExtractorEmailBody.php index c1e894d0..d8c8337e 100644 --- a/organizer/src/class/Extraction/ThreadEmailExtractorEmailBody.php +++ b/organizer/src/class/Extraction/ThreadEmailExtractorEmailBody.php @@ -8,39 +8,18 @@ require_once __DIR__ .
