We only need the user verifier for the purpose of user verification.
Once it's complete we should clear it so it doesn't get in the way
later.
This fixes a bug introduced in commit 3c8c5a5570 that leads to the
user session crashing when the login screen is reactivated.
https://bugzilla.gnome.org/show_bug.cgi?id=753181
We fade out the authentication prompt when a user successfully
logs into a user session. We reset it and fade it back in when
the user switches back to the login screen VT.
The problem is, we only fade it back in if the auth prompt status is
VERIFICATION_SUCCEEDED. It's possible for it to be NOT_VERIFYING
if the authprompt gets reset for some other reason in the interim.
This commit changes the check to be more precise. We now only skip
the fade-in, if we're already faded in, and we only skip the reset if
we're already reset.

The user should be allowed to cancel if verification hasn't
started yet and they're typing in their username. This
commit changes the authPrompt cancel function to not
ignore such requests.
https://bugzilla.gnome.org/show_bug.cgi?id=752739
Normally the user isn't allowed to proceed passed
the username question until they've filled it in.
To ensure this, the authprompt code desensitizes
the next button when the number of characters change to
zero.
Unfortunately it fails to desensitize the next button
up front when the entry starts out empty.
This commit addresses that bug.
https://bugzilla.gnome.org/show_bug.cgi?id=752739
If the next button ever gets set to Sign In, it won't
get reset to next until the next question asked by pam.
This commit ensures it gets reset to Next when asking
for the username.
https://bugzilla.gnome.org/show_bug.cgi?id=752739
We currently only cancel the user verifier on reset if
verifying, but that means we don't properly cancel it when
asking for a username at the Not Listed screen.
The object already handles getting called when there is
nothing to cancel, so just cancel it unconditionally.
https://bugzilla.gnome.org/show_bug.cgi?id=752438
It's possible for a user to type their password so quickly
that GDM hasn't even had time to ask for the password yet,
much less have time to process the answer.
In that situation, we tuck the user response away as
_preemptiveAnswer, and pass it along to GDM when GDM is finally
ready for it.
The problem is, there's a bug in the code, where we send
null for the service name in the answer, instead of the right
service name (say "gdm-password").
This commit addresses the bug by making sure we don't pass the
answer along, until the service name is properly set in
_queryingService. To ensure that, answering query (answerQuery)
based on _preemptiveAnswer has been shifted right below
this._queryingService = serviceName;

If the login screen actors aren't placed at pixel
boundaries then they will show up blurred with fuzzy
text.
This commit ensures all actor allocations are floored
to integer coordinates.
https://bugzilla.gnome.org/show_bug.cgi?id=746912
User read time per character has been changed from 16ms to 48ms because the
message of information about last login is displayed for half a sec that is not
a good user experience. So time to read a character is increased to 48ms from 16ms.
https://bugzilla.gnome.org/show_bug.cgi?id=720885
Currently the menu position below the button means that the menu
can extend to roughly half the screen height before ending up partly
off-screen. This is plenty of space for commonly installed sessions,
but some users have a significantly higher number of sessions in the
list. Move the menu to the side of the button in that case to maximize
the vertical space the menu may take up.
https://bugzilla.gnome.org/show_bug.cgi?id=734352
There's some vestigial code for hiding the user list
that runs at the same time its parent is hidden.
Only the parent should be hidden, at this point, so
there's situations where the user list hides and
never comes back.
This commit fixes that, by deleting the vestigial code.
https://bugzilla.gnome.org/show_bug.cgi?id=719418
We currently use the setActiveSession method to both mark a menu item as
selected, and also tell gdm about the current session the user selected.
Since gdm is ultimately in charge of the state, we should decouple this
and simply ask gdm to set the session, and have the menu item reflect
what gdm thinks is the current session.
This prevents state getting mismatched and oscillations from happening,
where we get in a loop of constantly telling gdm what the session is.

If a smartcard is missing from the reader when we start up,
and the system is configured to disable password authentication,
then we need to ask the user to insert their smartcard.
This commit fixes that.
https://bugzilla.gnome.org/show_bug.cgi?id=740143
The problem is caused by '_askForUsernameAndBeginVerification' being
called multiply times. So when we click 'next', the old connected
function will also be executed.
After the login banner is shown and hidden, the first user
in the user list becomes non-reactive. This is because the
banner is given an opacity of 0, but still allocated.
This commit fixes that by hiding the banner explicitly.
https://bugzilla.gnome.org/show_bug.cgi?id=743370
Normally when a user uses the login screen to log in, the
login screen gets killed and the user session takes over
the display.
This doesn't happen for wayland sessions, though. Instead,
the login screen gets reset, and the wayland session is started
on another VT.
The greeter proxy object needs to be recreated after this reset,
since it's associated with state no longer coupled to the login
screen after the reset.
This commit moves greeter proxy creation to happen at reset time.
https://bugzilla.gnome.org/show_bug.cgi?id=743371
Frequently banner messages are longer than can reasonable
fit in a one column view, which leads to a smooshed layout.
This commit changes the layout to a two column view, with the
banner on the left and the prompt on the right, if the banner
message is long enough that it can't fit well above the prompt.
If there isn't enough space for two columns then we keep the
one column layout but add scrollbars.

The login screen supports showing a banner message which admins
can use to mention login rules or disclaimers.
This message only shows up currently if the user list is enabled.
Most people who want to show a banner message also want to disable
the user list.
This commit moves the banner message to display when the user is
prompted for login credentials instead of when showing the user
list. It also adds a scrollbar if the message is too long.
https://bugzilla.gnome.org/show_bug.cgi?id=703972
The login screen is pretty custom full screen container and the standard
layout managers aren't really a good fit for the kind of layout that's
happening. This will be even more problematic with upcoming changes
to login banners, so we need to switch techniques.
This commit moves login dialog over to using a custom allocate handler
that has specific domain knowledge of the parts of the login screen
and where they go.
https://bugzilla.gnome.org/show_bug.cgi?id=703972
If the user list is disabled and the user clicks cancel quickly enough
after typing their username, they can get in a state where the
auth prompt gets stuck in the insensitive state.
This is because the login dialog code makes the prompt insensitive
while while pam is processing the provided username, but the prompt
only makes itself sensitive again when it is hidden.
This commit makes it sensitive right before asking for a username again.
https://bugzilla.gnome.org/show_bug.cgi?id=740141
Once verification has succeeded, the train's already
left the building and we shouldn't allow canceling.
This commit renders the cancel button non-reactive
and makes the cancel function be a noop after
verification succeeds.

Incorrect braces meant that if the ShellUserVerifier was destroyed before
the call to fprintManager.GetDefaultDeviceRemote(), the reply would result in
an error.

When a user logs in to a wayland session, we keep the login screen
running on the X server with the login screen running in a deactivated mode.
This commit makes sure it get reactivated when the user comes back to
the VT (from user switching, logout or just ctrl-alt-f1).
https://bugzilla.gnome.org/show_bug.cgi?id=726989
The smartcard service is put in the foreground in two cases:
1) If password service is disabled by admin configuratoin
2) if a smartcard is inserted
In either case we don't want to ask the user to pick a user from the
userlist. We currently only avoid asking in case 2.
This commit fixes case 1.
https://bugzilla.gnome.org/show_bug.cgi?id=726263
We only want to react to the card the user logged in with, at
the unlock screen. We check "at the unlock screen" by checking
the "reauthenticating" state variable. That variable is the
wrong one, though. It gets set too late, and in some cases, gets
set at the login screen, too. We should be checking this._reauthOnly
instead.
This commit fixes that.
https://bugzilla.gnome.org/show_bug.cgi?id=726262
Loading the user list can be expensive, for instance when there is
a large number of users and/or their avatars have to be fetched over
the network. In case the user list is disabled anyway, there is no
point in doing that work just to hide it, so stop doing that.
https://bugzilla.gnome.org/show_bug.cgi?id=725905
Right now we queue populating the user list in the middle of setting
up the dialog actors. Of course, the actual population happens some time
later after going back to the main loop.
It's more logical to structure the code so the the actors are
instantiated first in one block and then other things after that.
This commit moves the user list population enqueuing operation to the
bottom of the constuctor.
https://bugzilla.gnome.org/show_bug.cgi?id=721868
In some cases we load the user list after going back
to main loop and in other cases we load the user list
right away (depending on if accounts service is ready).
In the case we load the user list right away we cause a
traceback because loading the user list forces a reset,
which then tries to reset actors which aren't instantiated
yet.
This commit ensures the user list is loaded after the constructor
finishes and the event loop runs irregardless of the accountsservice
state.
