Impossibile inviare un determinato messaggio in chat

Firepup650 · 17 Settembre 2024, 12:56am

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:

Kinda long log

Sta cercando di inserire nella tabella chat e la colonna è limitata a 1000 caratteri.

Forse prova questo in data explorer:

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

C’è una lunghezza massima definita in qualche modo nel tuo schema?

value too long for type character varying(1000) mi indica che è correlato all’estratto. Questo è sorprendente perché tecnicamente limitiamo gli estratti a 150 caratteri, quindi questo caso non dovrebbe mai verificarsi. Inizialmente ho pensato che fosse un bug nel nostro generatore di estratti, ma guardando il codice dell’estratto in chat ho visto questo:

def build_excerpt
  # mostra solo l'URL se l'intero messaggio è un URL, perché non possiamo estrarre onebox
  return message if UrlHelper.relaxed_parse(message).is_a?(URI)

  # i messaggi solo di upload sono meglio rappresentati come il nome del file
  return uploads.first.original_filename if cooked.blank? && uploads.present?

  # questo potrebbe restituire vuoto per alcune cose complesse come le citazioni, il che è accettabile
  PrettyText.excerpt(cooked, EXCERPT_LENGTH, strip_links: true, keep_mentions: true)
end

Un rapido debug ha dimostrato che in realtà non raggiungiamo mai PrettyText.excerpt e ci fermiamo al primo return. Apparentemente i ??? fanno credere al nostro codice che si tratti di un URL:

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

Abbiamo identificato la correzione, ma ci vorrà del tempo per implementarla nella versione principale.
