WikiBugs/CamelCaseImageUploadCausesProblemsWithDisplay

Fixed in 1.0.2 --MarkusLude

---

Enable uploads and upload an image with a CamelCase name, for example CamelCase.png. Then try to display the image inline with this code:

upload:CamelCase.png

Rather than getting an inline image, it shows the word CamelCase as a missing document (clickable question mark to create a new document, provided, of course, the document doesn't exist):

upload:CamelCase?.png

and "upload:CamelCase" is a link to the image (without its extension).

upload:lowercase.png works as I would expect.

If the wiki page CamelCase actually exists, my system shows the image properly.

---

I can confirm this as well. Can anyone offer a fix?

Workaround: Set $WikiLinks to 0. (But then if you've been relying on the wiki link style, you're out of luck.)

I tried prefixing "(?<!upload:)" (a negative look-behind) on $LinkPattern but still had problems. If the filename is something like MyCamelCase.png, the link is to the document CamelCase.... so this fixes my problem. It may make a problem for you, though ;-)

The fix is to ensure wiki-style links' names are the starts of their words.

Side-effects:

• "whatAboutUnconventionalSpellings?" no longer links to the document "AboutUnconventionalSpellings?". It is no longer a link.

This patch did not work for me it trashed other links types. So I just moved

    if ($UseUpload) {
      s/$UploadPattern/&StoreUpload($1)/geo;
    }

to just after the EvalLocalRules? in CommonMarkup.

That works quite nicely! Thanks! -- Ke4roh

I may have sinned by editing my patch after posting it, editing it with bug fixes. I'm curious now if you applied the patch above or the old patch that I know would trash other link types. I haven't figured out what link types this patch might trash yet. Thanks! -- Ke4roh

I also think moving these three lines up a bit is the correct approach - but they only need to go to just above the "if ($WikiLinks) {" line (about 9 lines up). -- DavidClaughton
