Max length of the comment's content using ticket.update()

[Anonymous]

Hi,

I'm using XMLRPC to automatically add comments on existing tickets in Trac. So, I'm mostly using ticket.update().

It was working well, until I had the case of a comment too long. I had an error "data too long". Actually, the comment contained almost 1,000 lines...

I can understand that there is a limit, but I didn't find the value of this limit.

What is the max length of the comment's content ?

Then, I could modify my script to deal with this limit.

Thank you !

If you are using MySQL, the limitation is caused by that Trac uses text type, max is 65536 characters. See ​trac:#8396.

There's also [ticket] max_comment_size (TracIni#ticket-section) which will be applicable for all databases, but I haven't looked at whether it's enforced when adding a comment through XmlRpc.

I also found the value : 262,144 characters max for comment's content.
That corresponds to the constant [ticket] max_comment_size

Thank you !
