--- Comment #2 from Sergey Katunin <sulmp...@yandex.ru> --- (In reply to Magnus Boman from comment #0) > With kio 5.249.0 I can no longer open plain text documents on my NFS share I think you mean it's not that you can't open them at all by specifying a text editor manually, but that it doesn't open a file automatically through the default editor for text files. In general, the current behavior corresponds to the behavior of kio-fuse (protocols in dolphin like nfs://, webdav://) because it defines the type by extension via the Qt method `QMimeDatabase::mimeTypeForUrl` by remote url. > An option to disable this behavior would be greatly appreciated. This is of course one of the solutions, but I would like to suggest a different one. When you open the file, `KIO::OpenUrlJob` is executed by Dolphin, which in turn can call `KIO::MimeTypeFinderJob` to determine the mimetype (and this determination is more complicated than just by extension and, accordingly, defines a text file). The problem is that Dolphin calls the `KIO::OpenUrlJob` with an explicit indication of the mimetype that it defined earlier by extension - https://invent.kde.org/system/dolphin/-/commit/3b4676b3871cad5cd0e4695b211581f8db8accd0 (and mimetype most likely was determined here https://invent.kde.org/system/dolphin/-/blob/7f3967cf38f8ab707681981dd0bc6b220c3dbf83/src/kitemviews/kfileitemmodel.cpp#L1864, but it doesn't matter). This leads to the fact that `KIO::OpenUrlJob` does not call the `KIO::MimeTypeFinderJob`, and tries to open a file with the type "application/octet-stream". So, I suggest one of the following solutions: 1. If mimetype "application/octet-stream" and fileItem.isSlow() (so, it is this case with remote file with no extension) then call `KIO::OpenUrlJob` in Dolphin when opening a file without specifying the mimetype. If we do that, than `KIO::OpenUrlJob` will call `KIO::MimeTypeFinderJob` and determine mimetype, and I think it is okay to determine mimetype by content here, because we are opening file anyway and downloading a file for this here is not the same as downloading files in the background to determine the type when just opening a folder (like it was before PR with determining mimetypes from extensions for remote FS). 2. Determine the situation with mimetype "application/octet-stream" and fileItem.isSlow() inside `KIO::OpenUrlJob`, even if the "application/octet-stream" mimetype was specified explicitly when creating the job in Dolphin. I think first solution is a more suitable place, but the second solution may be able to solve a similar problem when this job is called not by Dolphin, but by some other program with the same purpose. After that, if we would open plain text file via click enter or mouse button, Dolphin will open file in default text editor. -- You are receiving this mail because: You are watching all bug changes.
