bolt: [Bug] Failed to parse SVG image with text/html mime type

After updating Bolt to 3.2.9, the “Select from Server” function in the backend does not work anymore, the dialog shows a spinning dotted disk and then fails with a reload symbol. This is likely to be a config specific error and not a general Bolt 3.2.9 error since other people (running 3.2.9) dont experience this behaviour. The same error occurs on the local staging server running php 5.6 / nginx and the “production” server running apache. i doublechecked file permissions and file / dir ownerships on both machines. As in the other referenced issue, “Upload File” and “Select from Stack” still works fine.

Details

Bolt 3.2.9
Composer Install
PHP version: [ 5.6 & 7.0 ]
Used web server: [ Apache & Nginx ] nginx 1.11
All Browsers

Browser Console error: Failed to load resource: the server responded with a status of 500 (Internal Server Error)

Nginx Error Log:

probably unrelated since the same error happens with nginx and apache: http://serverfault.com/questions/587386/an-upstream-response-is-buffered-to-a-temporary-file

maybe related but unlike in this issue, a different php version didnt solve the issue (tried on Apache with php 5.6 & php 7 - and on nginx with php 5.6) https://github.com/bolt/bolt/issues/4745

Still could be a rewrite issue, but the servers are using unmodified versions of the Nginx config example and the .htaccess file from the bolt distribution - so no idea how to fix this.

@cdowdy didn’t know GitHub supported collapsible blocks, thanks for that 😉

finfo still doesn’t work and since we you all are using bolt’s version of flysystem this wont work you’ll get null or text/plain using finfo

Flysystem uses Finfo.

flysystem needs the <?xml version="1.0" encoding="utf-8"?> block in the head…

Yes, that fixes the detection for the “bad” svg image.

Maybe we could do something like this:

$type = Flysystem\Util::guessMimeType($file, $data);
if ($type === 'text/html' && strpos($data, '<svg') === 0) {
    $data = '<?xml version="1.0" encoding="utf-8"?>' . $data;
    $type = Flysystem\Util::guessMimeType($file, $data);
}
