This commit prepares the frontend code to be consumed by webpack.
It is a hack: In theory, modules should be declaring and importing the
modules they depend on and the globals they expose directly.
However, that requires significant per-module work, which we don't
really want to block moving our toolchain to webpack on.
So we expose the modules by setting window.varName = varName; as
needed in the js files.
With past logic, on fast upload progress bar don't appears because
uploadFinished is called as soon as upload is finished so
progress bar get disappeared. To make these hiding of progress bar
smooth we set setTimeout for every hiding of progress bar as well
as complete status element.
Here `file.lastModified` is unique for each upload so it is used
to track each upload individually.
Also, we have used `uploadStarted` function because it is
called for each file during an upload.
Fixes: #9068.
Previous logic was little buggy, as many time there can be considerable
difference between uploadFinished and progressUpdated as progressUpdated
can finish much earlier(on a slow connection) and the "uploaded file"
markdown text is inserted with some delay.
It is also a preliminary commit for making each progress bar independent
as currently progressUpdated may close upload_bar even after only
one file out of many files is uploaded.
We used uploadStarted for drop callback which is kind of confusing
for new contributors as there is a big difference between uploadStarted
and drop like uploadStarted is called for each file in an upload whereas
the drop is called once when the file(s) are uploaded.
There was already a progress bar set up, but it became non-functional
after refactoring. This fixes it.
The default animation was getting cut off when `uploadFinished` is
called, so we add a delay before removing the upload bar to make it
get to the end.
Tweaked by tabbott to have a more natural feeling animation setup
(where we don't animate the width adjustments; just the disappearance
of the bar).
Fixes#8863.
This provides a slightly clearer interface, allowing us to remove the
unnecessary split of the code for the clone_file_input concept across
multiple modules (we now just clone it on-demand).
If your cursor is in the middle of a word when you upload
an image, the code will now properly put spaces in the markdown
around the attachment link.
Fixes: #7212.
Now, all the various DOM elements are named by a variable, keyed off
the configuration of the upload_options object.
This is most of the work required to support file upload in the
message edit area.
This is a nonfunctional refactor that is key preparation for allowing
uploading files in message editing.
Note that this makes no actual changes to the code; it just changes
the function structure.
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.
Based in part on work by Vishnu Ks (hackerkid).
Tweaked by tabbott to move changes from the next commit that are
required for this to pass tests into this commit.
Note that this exports a few items that were not previously exported.
