We currently will always allocate the user list's preferred size, so it
will grow indefinitely and never scroll; limit the height instead to
get the desired scrolling behavior when necessary.
https://bugzilla.gnome.org/show_bug.cgi?id=754525
When the user successfully types their password, we should hide
the spinner from the button well right away, so it doesn't
consume resources until reset (which may happen significantly later
if the user is vt switched away)
https://bugzilla.gnome.org/show_bug.cgi?id=753891
The code previously tried to stop spinner after it was hidden, but
due to an incorrect check was only stoppig it after it was shown.
Also, it was only stopping after hiding due to an animation, and
failing to stop it in the non-animated case.
This left the spinner hidden and running while VT switched away
from the login screen, only stopping when the auth prompt was
reset when switching back.
https://bugzilla.gnome.org/show_bug.cgi?id=753891
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.
https://bugzilla.gnome.org/show_bug.cgi?id=753181
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;
https://bugzilla.gnome.org/show_bug.cgi?id=737586
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.
https://bugzilla.gnome.org/show_bug.cgi?id=740142
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.
https://bugzilla.gnome.org/show_bug.cgi?id=703972
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.
https://bugzilla.gnome.org/show_bug.cgi?id=740141
Incorrect braces meant that if the ShellUserVerifier was destroyed before
the call to fprintManager.GetDefaultDeviceRemote(), the reply would result in
an error.
https://bugzilla.gnome.org/show_bug.cgi?id=738256
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.
https://bugzilla.gnome.org/show_bug.cgi?id=721868
When set to fill, the label will always end up left-aligned, which
is only correct in LTR locales. Set the alignment explicitly to
work in both RTL and LTR locales.
https://bugzilla.gnome.org/show_bug.cgi?id=712638
After a user types in their password at the login screen, one
of two things can happen
1) a new session is started
2) an existing session is switched to
In the latter case, GDM sends a reset signal to the login screen,
so it knows to go back to the user list and wait to be summoned
again.
Unfortunately, all reset signals are ignored after verification
success. The reason is because the reset handler was copied from
the unlock dialog as part of a deduplication effort in commit
7e7295f259 and the unlock dialog
handler at the time also emitted a "failed" signal on reset
(which wouldn't make sense to emit after success).
These days "failed" is handled in a different way.
This commit changes the code to let reset signals through after
successful verification.
https://bugzilla.gnome.org/show_bug.cgi?id=710456
oVirt is software for managing medium-to-large scale deployments of
virtual machine guests across multiple hosts. It supports a feature
where users can authenticate with a central server and get
transparently connected to a guest system and then automatically get logged
into that guest to an associated user session.
Guests using old versions of GDM support this single-sign-on capability
by means of a greeter plugin, using the old greeter's extension
API.
This commit adds similar support to the gnome-shell based login screen.
How it works:
* The OVirtCredentialsManager singleton listens for
'org.ovirt.vdsm.Credentials.UserAuthenticated'
D-Bus signal on the system bus from the
'org.ovirt.vdsm.Credentials'
bus name. The service that provides that bus name is called
the oVirt guest agent. It is also responsible for interacting
with the the central server to get user credentials.
* This UserAuthenticated signal passes, as a parameter, the a token
which needs to be passed through to the PAM service that is specifically
set up to integrate with the oVirt authentication architecture.
The singleton object keeps the token internally so it can be queried
later on.
* The OVirtCredentialsManager emits a signal 'user-authenticated' on
it's object once the dbus signal is triggered
* When the 'user-authenticated' signal is emitted, the login screen
tells GDM to start user verification using the PAM service. The
authentication stack of the service includes a PAM module
provided by oVirt that securely retrieves user credentials
from the oVirt guest agent. The PAM module then forwards those
credentials on to other modules in the stack so, e.g.,
the user's gnome keyring can be automatically unlocked.
* In case of the screen shield being visible, it also will react on that
'user-authenticated' signal and lift the shield.
In that case the login screen will check on construction time if
the signal has already been triggered, and a token is available.
If a token is available it will immediately trigger the functionality
as described above.

A conversation is finished after failing, and we are expecting a new
one to be started shortly after. However if we encounter an existing
reference to a previously set _queryingService, we will clear the
password entry, which might already contain a partially typed password
at that point. The behavior does make sense in the case of conflicting
conversations, but in the failure case it is both unexpected and
annoying, so clear _queryingService early to prevent this.
https://bugzilla.gnome.org/show_bug.cgi?id=708186
Right now we only show the session menu button when verifying,
but we should also show it when verification is failed or we
can end up in situation where the session menu disappears during
an authentication retry.
https://bugzilla.gnome.org/show_bug.cgi?id=707064
This commit consolidates the styles of the various
message types into one 'login-dialog-message' style
and then adds additional styles on top to cover the
differences.
This allows us to give the message label an initial
style so that is padded properly before any messages
are displayed.
https://bugzilla.gnome.org/show_bug.cgi?id=706670
Right now, we rely on PAM to ask for the username if disable-user-list
is TRUE. This is suboptimal because it means we can't check if we
should show a session menu.
This commit changes disable-user-list==TRUE to ask for a username up
front, rather than have PAM do it.
https://bugzilla.gnome.org/show_bug.cgi?id=706607
This commit detects when a user inserts a smartcard,
and then initiates user verification using the gdm-smartcard
PAM service.
Likewise, if a user removes their smartcard, password verification
(or the user list depending on auth mode and configuration) are initiated
https://bugzilla.gnome.org/show_bug.cgi?id=683437
The duplication makes the function look a lot more complicated
than it actually is.
This commit moves the common code to a new _startService function.
https://bugzilla.gnome.org/show_bug.cgi?id=683437
Some pam modules prompt without expecting the user to type
an answer back (e.g. "Please swipe finger"). We need to
emit prompted in this case too, so the the dialog will get shown.
https://bugzilla.gnome.org/show_bug.cgi?id=683437
Currently, fingerprint authentication is always a secondary thing.
If a user wants to swipe their finger when the computer is asking
for a password, so be it.
This commit paves the way for making fingerprint auth optionally
be the main way to authenticate. Currently there's no way to enable
this, but in a future commit will honor
enable-password-authentication=false
in gsettings.
https://bugzilla.gnome.org/show_bug.cgi?id=683437
Right now, the primary way a user logs in is with
a password. They can also swipe their finger, if their
fingerprint is enrolled, but it's expected the fingerprint
auth service won't ask questions the user has to respond to
by typing. As such, we ignore questions that comes from
anything but the main auth service: gdm-password.
In the future, if a user inserts a smartcard, we'll want
to treat the gdm-smartcard service as the main auth service,
and let any questions from it get to the user.
This commit tries to prepare for that eventuality by storing
the name of the default auth service away in a _defaultService variable
before verification has begun, and then later checking incoming
queries against that service instead of checking against
string 'gdm-password' directly.
Of course, right now, _defaultService is always gdm-password.
https://bugzilla.gnome.org/show_bug.cgi?id=683437
This commit introduces a new BeginRequestType enum which gets
passed to the 'reset' signal to specify whether
a username should be provided to the begin() method and changes
the loginDialog to comply.
Currently, the signal only ever gets emitted with
AuthPrompt.BeginRequestType.PROVIDE_USERNAME
but that will change in the future when providing smartcard
support.
https://bugzilla.gnome.org/show_bug.cgi?id=683437
We currently emit "failed" any time the UserVerifier is reset,
and user verification didn't succeed prior.
A more conceptually clear time to emit "failed" would be if
the UserVerifier is reset and user verification failed prior,
and to emit "failed" if the user cancels unlock.
This commit restructures things to do that. Aside from being
more conceptually clear, it also lays the groundwork for us
to be able to reset the unlock screen without failing.
https://bugzilla.gnome.org/show_bug.cgi?id=683437
authPrompt.reset() currently only leaves the authPrompt in a
sane state if the user isn't verifying.
This commit makes sure to cancel verification if a reset happens
while verification is in process.

Swap out the implementation of SystemIndicator with a dummy,
and build the aggregate menu. At the same time, remove the
poweroff and login screen menus, as those were fake aggregate
menus beforehand.
We lose some flexibility as we lose session-mode-based menu
layout, but as each component of the aggregate menu is supposed
to be "smart" in response to updating itself when session
state changes, I believe it's better than a declarative model.
https://bugzilla.gnome.org/show_bug.cgi?id=705845
We can't silently replace the old behavior of separate status
icons into a new system. Replace SystemStatusButton with a new
SystemIndicator class which will allow for the flexibility we
need. For now, make it a subclass of Button so that it mostly
feels the same, but we'll soon be swapping it out with a dummy
implementation that the aggregate menu will use.
I think the code cleanup here is worth it.
https://bugzilla.gnome.org/show_bug.cgi?id=705845
onAskQuestion has this code:
if (this.verifyingUser)
this.cancelButton.show();
else
this.cancelButton.hide();
but onAskQuestion can only be called when this.verifyingUser is true.
Also, cancelButton is public, and it only ever otherwise gets hidden
from callers.
This commit drops mucking with cancelButton visibility, leaving it
entirely up to the callers to deal with.
https://bugzilla.gnome.org/show_bug.cgi?id=683437
If the first question asked to a user is from the
shell and not from the PAM service (i.e. Username: ),
then we'll save what the user types until PAM asks
a question and then try to send it to PAM.
This commit makes sure the preemptive answer can be used
before the PAM conversation gets started, and makes sure
to discard the preemptive answer if we're not expecting it.
https://bugzilla.gnome.org/show_bug.cgi?id=705370
Right now we have two booleans that specify when user verification
is happening and when it succeeded, respectively.
This commit consolidates them into one AuthPromptStatus enumeration.
This clean up will allow us to check for verification failure more
easily.
https://bugzilla.gnome.org/show_bug.cgi?id=683437
The only time we ever call _reset directly is when
detecting changes to disable-user-list. We can implicitly
trigger a reset for this case, just as easily by calling
this._authPrompt.reset()
This commit makes that change for consistency and to make
it easier to adjust the authprompt workflow later.
https://bugzilla.gnome.org/show_bug.cgi?id=683437
Right now the whole authPrompt spreads out if a PAM message
comes in that longer than the entry.
This commit changes it to wrap instead, by forcing the
auth prompt to be a fixed width (slightly bigger than
the entry width was sized to previously).
https://bugzilla.gnome.org/show_bug.cgi?id=705037
When a ShellUserVerifier is asked to verify a user at the login
screen it will transparently first try to reauthenticate the user
against an existing session and then fall back to logging a user
into a new session. The former is used for user switching.
It's useful to know which type of verification is happening, so
the next button can be made to say "Unlock" instead of "Sign In" when
a user is already signed in.
This commit exports a new "reauthenticating" property on the
ShellUserVerifier that the auth prompt checks when deciding which
label to use for its next button.
https://bugzilla.gnome.org/show_bug.cgi?id=704795
If there are no messages in the queue and a user starts to
type then we can safely hide the message label since the
user has probably already read it.
This fixes a weirdness where "Incorrect Password" messages stay
around, even as the user types in the new correct password.
https://bugzilla.gnome.org/show_bug.cgi?id=704817
There's quite a bit of duplicated code between the login dialog
and the unlock dialog dealing with the various signals from the
ShellUserVerifier.
This commit moves that duplicated code into the AuthPrompt.
https://bugzilla.gnome.org/show_bug.cgi?id=704707
Right now there is a lot of duplicated code between the unlock
dialog and the login dialog.
This commit moves the login dialog's auth prompt to a separate

unlock dialog.
https://bugzilla.gnome.org/show_bug.cgi?id=702308
A bug got introduced when moving the login dialog away from modal
dialog, such that it listens for escape key presses in a mouse
event handler instead of a keyboard event handler.
This commit fixes that code to correctly listen for key-press-event
instead of button-press-event.
https://bugzilla.gnome.org/show_bug.cgi?id=702308
Right now if disable-user-list is true we show it briefly, just so
that we can fade it out to the user entry.
This commit avoids the fade in that case.
https://bugzilla.gnome.org/show_bug.cgi?id=704471
this._clearMessageQueue() is a noop when this.hasPendingMessages is
false so calling it in that case doesn't make sense.
This commit drops that call.
https://bugzilla.gnome.org/show_bug.cgi?id=704347
Now that we preallocate space for the prompt message there is
a lot of loose space between the entry and the buttons.
This commit helps tighten things up by getting rid
of the large top padding set above the login buttons.

commit ea02380c15 changed the login
dialog to not use ModalDialog anymore. There's still one lingering
setInitialKeyFocus method call in the source, which will cause an

https://bugzilla.gnome.org/show_bug.cgi?id=703874
There are some issues with the existing session menu. First, it looks
kinda bad. It seems like it's hanging around there, but it doesn't really know
what to do with itself.
Second, when it expands down it requires that the buttons below move
down with it. This kind of movement is awkward and looks a bit weird.
Third, its current position makes the "dialog" tall and unwieldy when
you add things like messages for fingerprint readers or authentication errors.
This commit moves the session list to a menu behind a button to address
the above problems.
Based on a patch by Jasper St. Pierre.
https://bugzilla.gnome.org/show_bug.cgi?id=702818
Right now, there's a weird flicker at start up where the
Not Listed? button shows up before the user list, which looks
pretty bad if you're watching for it.
This commit fixes that problem by hiding the Not Listed button
initially and showing it at the appropriate time.
https://bugzilla.gnome.org/show_bug.cgi?id=703132
The login screen is no longer even remotely dialog-like, so
using ModalDialog is pretty weird. It also makes it difficult
to put the session list in the same place as the spinner.
This commit moves loginDialog away from using modal dialog.
https://bugzilla.gnome.org/show_bug.cgi?id=702818
The optional logo on the login screen is currently shown in the
top bar, which is not only a rather unprominent position, it also
gives the wrong suggestion of a clickable element.
Newer designs call for the logo to be shown horizontally centered
at the bottom of the screen, so implement that instead.
https://bugzilla.gnome.org/show_bug.cgi?id=694912
For classic mode, we want to use a different styling for the spinner,
so we will pick up the image filename from CSS to make use of mode
specific styling. As the CSS will give us a full pathname, adapt the
API to take a full pathname instead of building it inside AnimatedIcon
from the passed basename.
https://bugzilla.gnome.org/show_bug.cgi?id=693688
Right now, if multiple messages come in, they just sort of
clobber each other.
This commit sets up a message queue, and introduces pauses
long enough for the user to hopefully be able to read those
messages.
https://bugzilla.gnome.org/show_bug.cgi?id=694688
Right, the common code between the login screen and
the unlock screen handles clearing the user verifier
when GDM sends a reset.
We don't actually always want to clear the messages on
reset in the unlock case, though, so doing it implicitly
is problematic.
This commit moves the clear() call from the common code
to the specific reset handlers.
https://bugzilla.gnome.org/show_bug.cgi?id=694688
Some of the conditions for showing the user list were not
properly inverted, causing the session list to be hidden
when it shouldn't be and shown when it shouldn't be.
https://bugzilla.gnome.org/show_bug.cgi?id=694784
We disable the entry after a user answers a question while we
process it, but we don't reactivate it later if asked another
one.
This commit makes sure the entry is always reactive when we
are waiting for an answer from the user.
https://bugzilla.gnome.org/show_bug.cgi?id=691806
The user list and the "Not Listed?" button get shown and hidden at the
same time, so we can simplify the code by putting them in a new
subcontainer.
This commit creates a userSelectionBox container that both actors get
put in, and changes all the code that shows and hides these actors to
show and hide userSelectionBox instead.
https://bugzilla.gnome.org/show_bug.cgi?id=694062
The sessionList and the prompt hint are all really
part of the prompt, so we should have the code that
hides those things in hidePrompt instead of in
showUserList.
This commit does that.
https://bugzilla.gnome.org/show_bug.cgi?id=694062
Right now, when a user item is clicked we remove all other users from
the list and position the item in the appropriate place on screen.
Ultimately, we're going to want to crossfade from the fully populated
list to the user prompt. Since we're going to need to show the user
avatar in two different positions we can't simply move it.
This commit leaves the user item for the user list, and instead shows
a UserWidget actor during user verification, in the same way the
unlock dialog shows a UserWidget actor during reauthentication.
https://bugzilla.gnome.org/show_bug.cgi?id=694062
Right now we very abruptly kill the login screen

This commit introduces a fade out of the dialog and
panels.

The latest mockups don't animate between states by
resizing actors. Instead, crossfades are employed.
This commit strips out many of the existing animations
as a first step toward implementing the new ones.

Since commit 1ae0fadbf4 we
no longer start a PAM conversation as soon as the user clicks
the "Not Listed?" button. Instead we defer starting the PAM
conversation until the user types their username.
Unfortunately, the cancel button resets the dialog back to the
user list indrectly by cancelling the current PAM conversation.
This means if the user hasn't yet entered thier username then
the cancel button doesn't work.
This commit performs a direct dialog reset in the case the
PAM conversation hasn't been started yet.

In a gdm session, we may not know what mouse orientation the user
may be in, so it makes sense to support both the left and right
mouse buttons to activate login or other items.
Additionally, add the behavior to all modal dialog items, even in
a user session, because it's unlikely that the user will right-click
on buttons, and it makes for an easier implementation.

Due to limitations and bugs in SpiderMonkey's GC, wrapper objects
for cairo contexts and similar may not get cleaned up immediately
after repainting, leading to leaking memory. Explicitly disposing
of such objects after they're not needed can clean up large portions
of memory for cairo surfaces.

We need to do a better job of indicating login process. This can
sometimes take a few seconds (particularly if you get your password
wrong): we need to give better feedback of what's going on.
This adds a spinner next to the login button if the authorization takes
some time.
https://bugzilla.gnome.org/show_bug.cgi?id=687113
The login dialog had these issues:
- the entry was not really disabled, you could still edit text
- the sensitivity state was not reset on verification failure
- the session list was not disabled
The unlock dialog had these issues:
- "Login as another user..." was not insensitive
- redundant password char setting, overwriting the one given by the
question
The entry insensitive style was also wrong.
https://bugzilla.gnome.org/show_bug.cgi?id=687113
For now we just use it to assign an identifier to modal modes in
which we want to allow some keybindings, but we don't use it for
any actual filtering; we'll start doing this shortly.
https://bugzilla.gnome.org/show_bug.cgi?id=688202
If I click on "Not listed?" in the login screen, I come to a username
field with two buttons: "Cancel" and "Sign In".
Clicking on "Sign In" doesn't actually sign me in though - it takes me
to the login entry. It would be better to rename "Sign In" to "Next" for
the username stage, therefore.
Gdm emit a signal to ask a question or a secret, but we can not know if
this is the last authentication question, hence we only use "Sign In"
for secret questions which improve the situation a lot.
https://bugzilla.gnome.org/show_bug.cgi?id=687656
In some deployments showing a user list at the login
screen is undesirable.
GDM's fallback login screen has a configuration key:
org.gnome.login-screen disable-user-list false
that causes the user-list to get hidden.
This commit adds similar functionality to the normal,
shell-based login screen.
Based on a series of patches by Marius Rieder.
https://bugzilla.gnome.org/show_bug.cgi?id=660660
Right now when a user clicks "Not Listed?" they end up
seeing a session list that gets reset after they enter their
username.
This commit hides the session list until the username has
been entered.
https://bugzilla.gnome.org/show_bug.cgi?id=660660
For the "Not Listed?" case we will need to be able
to identify when the user has entered their username.
Once we have a way of tracking when the username is
entered, we can then defer showing the session list
too early, before the user can reliably pick a
session.
This username tracking will also be important for
implementing a disable-user-list configuration key.
If the config key gets toggled off at runtime, we'll
need to know if we're at a disruptive part of
the authentication process or not, so we know whether
we can can expose the user list right away, or wait
until the authentication conversation finishes.
Right now, we pass null in for an initial username,
and let the PAM machinery ask the user, which means we
have no good way of knowing when the username is entered.
This commit changes the "Not Listed?" code to ask the
user their username up front, before starting the PAM
conversation in much the same way we do if the user
picks a user from the user list.
https://bugzilla.gnome.org/show_bug.cgi?id=660660
You can't login until something has been entered in the password field.
We should therefore make the login button insensitive until you have
entered some text.

If it is updated after checking, it counts the number of failures
not including the current one, so it allows one extra attempt. Instead,
by updating it before checking, we get the expected result of dropping the
curtain at the third password.
https://bugzilla.gnome.org/show_bug.cgi?id=687132
When the user has the entered the password for the second time
and clicked OK, clear messages from the previous attempt, so any
new failure is shown clearly.
https://bugzilla.gnome.org/show_bug.cgi?id=687132
GDM has a 'logo' key in its schema to allow distributors to add
some branding. It is currently placed above the user list, which
no longer works too well since the login screen lost its dialog
window. Display the logo in the top-left corner instead of the
Activities button instead.
https://bugzilla.gnome.org/show_bug.cgi?id=685852
Check an environment variable, GDM_GREETER_TEST. If 1, LoginDialog will
skip anything that fails outside a GDM session.
It is therefore possible to test the GDM greeter without installing it
system-wide, by attempting login as the already logged in user (uses the
same code path as the unlock dialog).
https://bugzilla.gnome.org/show_bug.cgi?id=683725
GDM's GSettings schema contains a 'disable-restart-buttons' key
that currently is only supported by the fallback greeter.
Implement support in the shell greeter as well.
https://bugzilla.gnome.org/show_bug.cgi?id=686247
Adding a group to the Ctrl-Alt-Tab popup will also add it to the
focus manager. Due to that, we currently end up with two focus
groups added for the login dialog - an explicit one for the entire
dialog, and an implicit one for the main content group.
When doing keynav, we ascend in the widget hierarchy from the
currently focused actor until we find a valid focus root, so
adding a children of the dialog as focus root breaks keynav to
any actors that are not inside the main content group.
The simple fix is to use the same group in both cases.
https://bugzilla.gnome.org/show_bug.cgi?id=684730
Now that we use a different text style for the username depending on
whether the user list is expanded or not, changing the :expanded style
before the actual transition looks disruptive. Adding the style right
before fading in other items and removing it right after fading them
out gives a better result.
https://bugzilla.gnome.org/show_bug.cgi?id=685201
Currently the layout of the password prompt differs slightly between
login dialog and unlock screen - for the former, the prompt is
displayed next to the user avatar, replacing the user name, for
the latter, it is diplayed below both avatar and name.
https://bugzilla.gnome.org/show_bug.cgi?id=685201
_moveFocusToItems seems to be called to early causing
clutter_actor_grab_key_focus not to be called.
So queue another attempt with BEFORE_REDRAW priority when
this happens to make sure we actually move the focus sucessfully.
https://bugzilla.gnome.org/show_bug.cgi?id=684650
Currently the default action is performed twice when pressing Return
in the login dialog, once in response to the entry's 'activate' signal,
and again by activating the default button. Usually this is not a
problem, as the second invocation is simply ignored, however it breaks
the case where multiple consecutive questions are asked (e.g. username
and password in the 'Not listed' case).
Fix the problem by not handling the 'activate' signal at all.
https://bugzilla.gnome.org/show_bug.cgi?id=685511
Instead of leaving the login or unlock dialogs in an inconsistent state,
catch DBus errors and show an Authentication Error message. The error
details are logged in the session logs.

commit e333263fd6 changed fingerprint.js
to not throw an exception when fprintd is uninstalled, by adding the
flags DO_NOT_LOAD_PROPERTIES and DO_NOT_AUTO_START
DO_NOT_LOAD_PROPERTIES is correct. Loading the properties is what makes
it fail at initialization time when not installed. DO_NOT_AUTO_START is
not correct though. It means fprintd will never get activated implicitly
when we need it.
This commit removes DO_NOT_AUTO_START thus making fprintd start when we
need it, but not fail at initialization time when not around.
https://bugzilla.gnome.org/show_bug.cgi?id=683131
Instead of showing a notification, add a small message immediately
below the entry, and give the user two more attempts to login,
before going back to the welcome or lock screen.
https://bugzilla.gnome.org/show_bug.cgi?id=682544
Ensure that all async callbacks check and ignore G_IO_ERROR_CANCELLED.
Ensure that all runs of authentication have their own GCancellable, so
that .begin() can be called multiple times on the same user verifier.
Check for fingerprint reader when beginning authentication, and not
when reset by GDM.

Otherwise the second attempt tot login after pressing "escape" key

The fingerprint message is useful for users that click their
names in the user list to let them know if fingerprint login
is available.
This same place on screen (below the login entry) can potentially
be used for other messages as well.
This commit changes the variable and style names surrounding
this feature to be more generic.
A subsequent commit will leverage this functionality to provide
a hint on how to log in to the local enterprise domain controller
(if relevant).

Various code around had different paths for ConsoleKit and
logind. Consolidate it by making an abstract class that all
callers can use, which hides the implementation details of the
two daemons.
https://bugzilla.gnome.org/show_bug.cgi?id=682096
In preparation for accessing it in the screenshield, factor out
common code for ConsoleKit and Systemd.
Also, clean up ConsoleKit manager, as the daemon is required in
a non systemd installation. In particular:
- We allow it to be autostarted at session startup (or really,
we expect it to be already there, started by GDM during session
opening).
- We no longer silently assume that the session is active if
it can't start.
https://bugzilla.gnome.org/show_bug.cgi?id=682096
GetUserVerifier can only be called from the greeter session,
and fails with AccessDenied in all other cases. Also, calling it
hides the real error from OpenReauthenticationChannel, which
instead should be logged.
https://bugzilla.gnome.org/show_bug.cgi?id=680750
Unlike the fallback gdm UI, we do not indicate in the user list
whether a user already has an open session or not. This information
is useful, so use a spotlight effect similar to the running-app
indicator to mark logged in users.
https://bugzilla.gnome.org/show_bug.cgi?id=658185
We want to style user list items differently depending on whether
the list is expanded or shrunk; instead of manually updating the
items' style, we can just expose the :expanded style on the list
itself and use that in the CSS.
https://bugzilla.gnome.org/show_bug.cgi?id=658185
The current animation time of two seconds may result in some
confusion, as the reason of the behavior only becomes apprent
when the auto-activating item becomes visible; make the animation
a lot faster and ease it out a bit.
https://bugzilla.gnome.org/show_bug.cgi?id=660913
Until the recent style changes, the same element was used to indicate
both item focus and progress for timed logins. As focus is now indicated
by the item's background style, rename the indicator from focusBin to
timedLoginIndicator and make some minor adjustments to better fit the
new style:
- move it next to the icon below the text
- give it a white color and a shadow
- update animation to grow from the left instead of the center
https://bugzilla.gnome.org/show_bug.cgi?id=660913
Rather than changing the text color to indicate hover and an underline
to mark the focused item, use the same semi-transparent white background
as in the overview.
https://bugzilla.gnome.org/show_bug.cgi?id=660913
The design calls for the curtain to appear in the gdm greeter too.
Implement this by having the screenshield manage the login dialog
(delegating its creation to SessionMode).
https://bugzilla.gnome.org/show_bug.cgi?id=619955
Add 'default' parameter to setButtons, that controls the binding
of Return (unless overridden) and applies the 'default' pseudo-class.
Currently it has no effect, but it will start having after the
login dialog redesign.

When setting an explicit size as we do currently, rounding errors
(for instance introduced by padding not specified in pixels) may
affect the parent's size allocation, e.g. making it shrink or grow
each time the size is reset.
Rather than taking care of possible rounding errors, set up focusBin
to take up the available width and use scaling for the animation.

When GDM was moved over to GDBus it dropped the libgdmgreeter
library and introduced a new libgdm library with a somewhat
different API.
The main differences in the API are:
1) open_connection is now implicit and automatic
2) conversations don't need to be started explicitly, they're
started just-in-time when verification is requested
3) The functions are split up between the client, and new
helper objects that correspond to the dbus interfaces
they were generated from (one for user verification,
one for greeter specific operations, and a couple more
that aren't used by gnome-shell).
4) libgdm supports reauthenticating in an already running
session, so user switching should now affect the users
session more like screen unlocking does.
This commit moves the shell over to the new library.
Based on work by Giovanni Campagna <gcampagna@src.gnome.org>
https://bugzilla.gnome.org/show_bug.cgi?id=676401
When using dbus-glib, single return values were special-cased to

We seem to have a lot of code that does something along the lines of:
if (condition)
actor.show();
else

ClutterActor already has such a thing for exactly this purpose: the 'visible'

ConsoleKit is obsoleted by systemd-logind. Accordingly, port
the current CK code to systemd. In order to be nice to
the Debian people fall back to CK if systemd is not found,
so that the code makes the best of whatever it runs on.
Commit 25948f214e replaced the old hardcoded scaling behavior of
background-images with the CSS-compliant option to control that
behavior with the background-size property. Fix some fallout from
the changed default scaling behavior.
The last patch in the sequence. Every place that was previously
setting prototype has been ported to Lang.Class, to make code more
concise and allow for better toString().
https://bugzilla.gnome.org/show_bug.cgi?id=664436
All classes that have at least one other derived class (and thus
benefit from the framework) have been now ported. These includes
NMDevice, SearchProvider, AltTab.SwitcherList, and some other

Users don't expect the bullets they just typed into an entry
field to disappear as soon as they hit enter.
Instead, they want the dialog to become insensitive during the
authentication process, so that it's clear that what they typed
in is being processed.

Right now we show "(or swipe finger)" at the user login prompt
any time we detect a fingerprint reader.
Checking for the presense of a fingerprint reader isn't really
sufficient for knowing if it is appropriate or not to show the
message, though. Often, a user's fingerprint won't be enrolled
in the system even if the machine has a fingerprint reader.
In this scenario, we end up in a situation where the code will
fade out the message right after fading it in, or worse, fade
out the message while fading it in.
The former case looks flickery and bad, and the latter case
causes the login dialog to lock up since it never completes its
"show prompt" animation and we don't procede with the login
process until after that animation.
If a user is enrolled in the system, the fingerprint pam module
tries to tell the user to swipe their finger. We never show the
user that message because it's redundant with our own "(or swipe
finger)" message and because it uses techy words like "UPEK" and
"TouchStrip".
This commit changes the code to defer showing "(or swipe
finger)" until the fingerprint pam module forwards us its own
message. This makes it less likely we'll show the message when
fingerprint login won't work, and also removes the fingerprint
animation from the critical path "show prompt" animation.

If there's no scrollbar in the user list it grows as the

Making users have to log in to power off the machine isn't a good idea.

In order for transformation animations to look good, they need to be
incremental and have some order to them (e.g., fade out hidden items,
then shrink to close the void left over).
Chaining animations in this way can be error prone and wordy using just
Tweener callbacks.
This commit adds a new set of classes to help:
- Task. encapsulates schedulable work to be run in a specific scope.
- ConsecutiveBatch. runs a series of tasks in order and completes
when the last in the series finishes.
- ConcurrentBatch. runs a set of tasks at the same time and completes
when the last to finish completes.
- Hold. prevents a batch from completing the pending task until
the hold is released.
The tasks associated with a batch are specified in a list at batch
construction time as either task objects or plain functions.
Batches are task objects, themselves, so they can be nested.
For now, these APIs are temporarily getting staged in a gdm/ specific
subdirectory so they will be available for use by GDM. They aren't
specific to GDM, or even to doing animations, though, so the API may eventually
move in some form or another to a more general location. Alternatively, the
APIs may ultimately get dropped entirely and replaced by something else.
