For some reason on two different non-Meta forums, this exact message cannot be sent in chat:

Removing either the ??? from the first line, or the last line of that log snippet causes it to send properly.

For some reason, I cannot reproduce this on Meta however.

It causes the error both at https://forum.obl.ong/ and https://amcforum.wiki/, it causes a 500 error, logs from AMC are:

إنه يحاول الإدراج في جدول الدردشة والعمود محدود بـ 1000 حرف.

ربما جرب هذا في مستكشف البيانات:

SELECT
    column_name,
    data_type,
    character_maximum_length
FROM
    information_schema.columns
WHERE
    table_name = 'chat_messages'
    AND column_name IN ('cooked', 'message')

هل هناك حد أقصى للطول محدد بطريقة ما في مخططك؟

يشير value too long for type character varying(1000) بالنسبة لي إلى أنه متعلق بالملخص. هذا مفاجئ لأننا من الناحية الفنية نحد الملخصات عند 150 حرفًا، لذلك لا ينبغي أن تحدث هذه الحالة أبدًا. في البداية اعتقدت أنه خطأ في مُنشئ الملخصات الخاص بنا، ولكن بالنظر إلى كود الملخص في الدردشة رأيت هذا:

def build_excerpt
  # نعرض الرابط فقط إذا كانت الرسالة بأكملها رابطًا، لأننا لا نستطيع تلخيص الروابط المميزة
  return message if UrlHelper.relaxed_parse(message).is_a?(URI)

  # الرسائل التي تحتوي على مرفقات فقط يتم تمثيلها بشكل أفضل باسم الملف
  return uploads.first.original_filename if cooked.blank? && uploads.present?

  # قد يُرجع هذا قيمة فارغة لبعض الأشياء المعقدة مثل الاقتباسات، وهذا مقبول
  PrettyText.excerpt(cooked, EXCERPT_LENGTH, strip_links: true, keep_mentions: true)
end

أظهر التصحيح السريع أننا في الواقع لا نصل أبدًا إلى PrettyText.excerpt ونتوقف عند أول return. يبدو أن ??? يجعل الكود الخاص بنا يعتقد أن هذا رابط:

[1] pry(main)> UrlHelper.relaxed_parse("???\ntest").is_a?(URI)
=> true

لقد حددنا الإصلاح، لكن الأمر سيستغرق بعض الوقت حتى يتم تطبيقه في النظام الرئيسي.
