The commit f863a9b567 had modified
jquery.filedrop's paste method to exit early if any of the items in the
clipboardData is of the string kind. The early exit was added to prevent pasting
an image thumbnail for text copied from software like MS Word, instead of
pasting the actual copied text content. When copying an image in a (modern?)
Browser, though, the clipboard seems to contain a html `img` tag item, along
with the actual image file. This resulted in pastes being broken.
This commit modifies the condition checked for the early exit. We now actually
look at the html content in the clipboard to see if it is an `img` tag, in which
case we upload the image, instead of exiting early.
Closes#7130.
We were missing it but it is added in the upstream, so just added it
at the appropriate place in plugin code(in the upstream there is some
code refactoring but this seems to be the most appropriate place).
The first argument to the error callback is *usually* a string code
from a list in the filedrop source; but sometimes it was the text
the server sent in the HTTP status line, instead. The latter isn't
predictable, and so it's not possible to write app code that uses it
to handle error consistently.
Instead, use that parameter for the numeric HTTP status code. This
still isn't totally clean in that sometimes it's internal filedrop
errors, as strings, and sometimes it's HTTP status codes, as numbers;
but at least both of those are things we can sanely handle with a
`switch` statement.
Also pass through `serverResponse`, which for a nice JSON error from
the server will contain meaningful information about the error which
the calling code can use for nice error handling. And just drop the
HTTP status text, which at best is redundant with the numeric code.
In passing, fix one case where for no obvious reason filedrop was
passing the file object but not the index.
This should be a pure refactor.
We'll replace this primarily with per-realm quotas (plus the simple
per-file limit of settings.MAX_FILE_UPLOAD_SIZE, 25 MiB by default).
We do want per-user quotas too, but they'll need some more management
apparatus around them so an admin has a practical way to set them
differently for different users. And the error handling in this
existing code is rather confused. Just clear this feature out
entirely for now; then we'll build the per-realm version more cleanly,
and then we can later add back per-realm quotas modelled after that.
The migration to actually remove the field is in a subsequent commit.
