Description

The atom feed from a Project does not truncate the subjects, but using the link for All Projects does it.
Even using redmine.org > Projects > View all issues > Atom, issue 33965 is truncated:

    <title>Redmine - Defect #33965 (New): REST API: Method Not Available see used Status list as per the tra...</title>
    <link rel="alternate" href="https://www.redmine.org/issues/33965"/>

In fact, all atom feeds (not only for all project, but aslo por an individual project) are truncating issue subject to 100 chars.
Example in Redmine project:

    <title>Defect #33953 (Confirmed): Repository Tab will not showing if no repository is set as "Main repos...</title>
    <link rel="alternate" href="https://www.redmine.org/issues/33953"/>

The probelm with "all projects" is that it adds the Project's name as prefix, so it is easier to truncate the value

I agree that 100 chars is too short because the maximum length of Issue#title can be 255 chars. So, at least 255 chars of titles are handled without truncation.

Atom feeds are added in r670 in 2007. At that time, Redmine already trimmed down the title to 100 chars.

Also take into account that generating the atom from All Projects > View all issues, it adds the project's name as prefix in the title field, so it will have more characters....

The following patch changes the length limit of the title to 300. Since the maximum length of Issue#title is 255 chars, I think 300 is enough for most cases.

Why truncate to 300 if the column length is 255?

Maybe it's better to not truncate anymore.

Although the maximum length of a subject is 255, a feed title includes additional information such as tracker name and project name.

I agree. The max length of a project name and a tracker name is 255 and 30, so I don't think there is any problem without truncate.

The truncate was initially introduced in #1356.

When changing this to not truncate titles, we should still try to avoiding multi-line event titles (e.g. by cutting of on the first newline or at least transforming newlines to spaces as currently done in ApplicationHelper#truncate_single_line)

Thank you for the explanation.
I think my first patch in #note-4 is better than 34025.diff.

Setting the target version to 6.0.0.
