1517074 - Cannot save "HTML Only"

Status: VERIFIED FIXED

(Core :: Widget: Gtk, defect)

Description

[Dan Jacobson]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:64.0) Gecko/20100101 Firefox/64.0

Steps to reproduce:

1. CTRL+S Save Page As
2. Choose HTML only
3. Push Save


Actual results:

The choice is switched to "Webpage Complete" before the action begins.
(But that is too fast for the user to see.)
As is evidenced by what is saved on disk,
and as is evidenced by "Webpage Complete" being the default chosen the
next time the user hits CTRL+S.

So try as he may, "HTML Only" cannot really be chosen.
There always will be a directory created "..._files" anyway.

I can reproduce this with Firefox64 on Ubuntu18.04LTS and this is a regression.

[Jared Wein [:jaws] (please needinfo? me)]

Martin, could you look in to this as you reviewed the regressing patch?

Comment 3

[Martin Stránský [:stransky] (ni? me)]

Sure.

It's known Gtk+ issue - https://gitlab.gnome.org/GNOME/gtk/issues/1492.

Comment 5

[Martin Stránský [:stransky] (ni? me)]

Unfortunately there's no fix available for it. I tried to get the filter as a property from the dialog but it's saves as a property of an inner widget (GtkFileChooserWidget) and only when GtkFileChooserDialog fallback is used - so it's really hacky approach which may lead to even more failures.

I suggest to switch back to GtkFileChooserDialog and use GtkFileChooserNative under a pref which makes sense for KDE users and/or enable it for KDE only by default. When https://gitlab.gnome.org/GNOME/gtk/issues/1492 is fixed we can enable it for the appropriate Gtk+ version only.

Attachment: Bug 1517074 - [Linux/Gtk] Enable native (xdg-desktop based) file dialog on KDE only due to Gtk+ regression, r=jhorak

Also add widget.allow-gtk-native-file-chooser preference value to force enable on all systems.

Bug 1517074 - [Linux/Gtk] Enable native (xdg-desktop based) file dialog on KDE only due to Gtk+ regression, r=jhorak

[Triage Comment]
Works around a Linux-only GTK bug which causes "HTML Only" webpage saving to not work. Approved for 65.0b11.

I successfully reproduced the issue on Firefox Beta 64.0b4 under Ubuntu 18.04 (x64) using the STR from Comment 0.

The issue is no longer reproducible on Firefox Beta 65.0b11 and latest Nightly 66.0a1 (2019-01-15) under Ubuntu 18.04 (x64).

I see this with FF 74.0 from Fedora repos and Qt file dialog (GTK_USE_PORTAL=1).
Saving web page with "html only" - getting directory created also (while it shall not).

This still doesn't work despite https://gitlab.gnome.org/GNOME/gtk/issues/1492 having been fixed in the meantime. From my analysis, the problem is that 'gtk_file_chooser_get_filter' still does not work for 'GtkFileChooserNative', only 'gtk_file_chooser_set_filter' (i.e. the function to set preselect a specific filter, not to get the one that is finally selected) was implemented.

For 'gtk_file_chooser_get_filter', there is another upstream GNOME bug report that is still open: https://gitlab.gnome.org/GNOME/gtk/-/issues/1820

As a clarification, this does not work when using a portal (e.g. with 'GTK_USE_PORTAL=1' set).

That issue has been fixed now, so this also works now with 'GTK_USE_PORTAL=1' set when using the current development versions of gtk, xdg-desktop-portal and xdg-desktop-portal-gtk. For xdg-desktop-portal-kde (i.e. the KF5/KDE Plasma native file choosers), there is a pending merge request to fix it there as well at https://invent.kde.org/plasma/xdg-desktop-portal-kde/-/merge_requests/5/ .

See https://gitlab.gnome.org/GNOME/gtk/-/issues/1820 for more details.
