As explained in the commit message for the patch itself, this is +a ‘forgotten part’ from a previous page vs destpage fix which has +already been included upstream. + +> Applied. --[[Joey]] + +>> Thanks. + +The second patch, ‘inline: improve feed title and description +management’, aligns feed title and description management by introducing +a `title` option to complement `description`, and by basing the +description on the page description if the entry is missing. If no +description is provided by either the directive parameter or the page +metadata, we use a user-configurable default based on both the page +title and wiki name rather than hard-coding the wiki name as description. + +> Reviewing, this seems ok, but I don't like that +> `feed_desc_fmt` is "safe => 0". And I question if that needs +> to be configurable at all. I say, drop that configurable, and +> only use the page meta description (or wikiname for index). +> +> Oh, and could you indent your `elsif` the same as I? --[[Joey]] + +>> I hadn't even realized that I was nesting ifs inside else clauses, +>> sorry. I think you're also right about the safety of the key, after +>> all it only gets interpolated with known, safe strings. + +>>> I did not mean to imply that I thought it safe. --[[Joey]] + +>>>> Sorry for assuming you implied that. I do think it is safe, though +>>>> (I defaulted to not safe just to err on the safe side). + +>> The question is what to do for pages that do not have a description +>> (and are not the index). With your proposal, the Atom feed subtitle +>> would turn up empty.

But I see no reason to add the complexity +>>> of an option to configure a default value for a field that +>>> few RSS consumers likely even use. That's about 3 levels below useful. +>>> --[[Joey]] + +>>>> The way I see it, there are three possibilities for non-index pages +>>>> which have no description meta: (1) we leave the +>>>> description/subtitle in feed blank, per your current proposal here +>>>> (2) we hard-code some string to put there and (3) we make the +>>>> string to put there configurable. Honestly, I think option #1 sucks +>>>> aesthetically and option #2 is conceptually wrong (I'm against +>>>> hard-coding stuff in general), which leaves option #3: however +>>>> rarely used it would be, I still think it'd be better than #2 and +>>>> less unaesthetical than #1. + +>>>> I'm also not sure what's ‘complex’ about having such an option: +>>>> it's definitely not going to get much use, but does it hurt to have +>>>> it? I could understand not wasting time putting it in, but since +>>>> the code is written already … (but then again I'm known for being a +>>>> guy who loves options). + +The third patch, ‘inline: allow assigning an id to postform/feedlink’, +does just that. I don't currently use it, but it can be particularly +useful in the postform case for example for scriptable management of +multiple postforms in the same page. + +> Applied. --[[Joey]] + +>> Thanks. + +In one of my wiki setups I had a terminating '/' in `$config{url}`. You +mention that it should not be present, but I have not seen this +requirement described anywhere. Rather than restricting the user input, +I propose a patch that prevents double slashes from appearing in links +created by `urlto()` by fixing the routine itself. + +> If this is fixed I would rather not put the overhead of fixing it in +> every call to `urlto`. And I'm not sure this is a comprehensive +> fix to every problem a trailing slash in the url could cause. --[[Joey]] + +>> Maybe something that sanitizes the config value would be better instead? +>> What is the policy about automatic changing user config? + +>>> It's impossible to do for perl-format setup files. --[[Joey]] + +>>>> Ok. In that case I think that we should document that it must be +>>>> slash-less. I'll cook up a patch in that sense. + +The inline plugin is also updated (in a separate patch) to use `urlto()` +rather than hand-coding the feed urls. You might want to keep this +change even if you discard the urlto patch. + +> IIRC, I was missing a proof that this always resulted in identical urls, +> which is necessary to prevent flooding. I need such a proof before I can +> apply that. --[[Joey]] + +>> Well, the URL would obviously change if the `$config{url}` ended in +>> slash and the `urlto` patch (or other equivalent) went into effect. + +>> Aside from that, if I read the code correctly, the only other extra +>> thing that `urlto` does is to `beautify_url_path` the `"/".$to` part, +>> and the only way this would cause the url to be altered is if the +>> feed name was "index" (which can easily happen) and +>> `$config{htmlext}` was set to something like `.rss` or +>> `.rss.1`. + +>> So there is a remote possibility that a different URL would be +>> produced.
