Firefox sent an accept header for application/xml, not application/json,
and also weakened the priority to 0.8. So that stuff is not to be trusted;
instead I found a better way: When an ajax upload is *not* being made,
the Upload Attachment button will be used, so enable ajax if an upload
is being made without that button having been used.
Also, testing with firefox revealed it refused to process a response that
was type application/json, and checking the demo page for the jquery file
upload plugin, it actually returns the json with type text/html. Ugh.
Followed suite.
Now tested with: chromium, chromium (w/o js), firefox, firefox (w/o js),
and w3m.
Needed for attachment to return json when requested.
I think some browsers send Accept: * , so I made sure to check that json
was explicitly listed as to be accepted, as well as having a high
priority.
removed most of the css, going for standard plain ikiwiki look
Removed support for image previews, file size limits, delete buttons,
maximum number of files, file size display. Ikiwiki handles all that.
Turned on autoupload.
Left out confirmation of removal for held attachments because
a) they're not in the wiki yet, so confirmation is a bit unnecessary
b) it would be hard
c) eases later integration of jquery file upload interface
Also changed where attachments of index are held (to match where they're
stored in the srcdir).
Note that the attachment formbuilder hook was made to run last, so that
the list of attachments is not generated before removal, in the fast path
w/o confirm.
Note that it's possible for an attachment in the holding area to be older
than an attachemnt in the wiki with the same name. I intentionally
show the one in the holding area in this (unlikely) case, since saving the
page will overwrite the wiki's file with the held attachment. It does not
seem worth the bother of doing something more intelligent, since in this
case two people have basically conflicted with one-another.. and both
attachment contents will be stored in revision control in case it needs to
be sorted out.
I had to remove the hyperlink for attachments in the holding area, since
they're not yet live on the web. This could be annoying/confusing. Added
a moseover notice instead.
