[Bug 2051371] Re: Backspace in gnome-terminal often deletes cluster

2024-01-26 Thread Egmont Koblinger
Maybe the bug you _really_ wanted to report is that gnome-terminal
doesn't use the "surrounding text" feature of input methods?

[Bug 2051371] Re: Backspace in gnome-terminal often deletes cluster

2024-01-26 Thread Egmont Koblinger
By the way... absolutely independently from terminals...

U+17d2 is a combining accent. When I checked (many years ago), major
graphical toolkits (e.g. GTK and QT) disagreed whether the backspace
keypress should delete only the combining accent, or the entire glyph
(base character + combining accents) at once. GTK did one, QT did the
other (I can't recall which one did which).

I don't know if the world has changed since and has settled with one of
these behaviors, having found out that one of these behaviors is clearly
superior to the other. I would _guess_ that not much has changed. That
is, both possible behaviors are reasonable, both have their pros and
cons, and probably you cannot claim that the behavior _must_ be the one
you're looking for.

If your input method cannot generate the symbols you need, and you need
to press backspace as a workaround to get that, moreover, you need to
rely on one particular behavior of backspace, then I'd argue that it's
all the fault of your input method, it should be able to produce
straight away whatever you wish to end up with.

[Bug 2051381] Re: gnome-terminal-server crashed with SIGSEGV in g_utf8_pointer_to_offset()

2024-01-26 Thread Egmont Koblinger
Correct me please if I'm wrong, but it looks to me that you have studied
the relevant source code and even located the problem in one of the ibus
related package.

So I'm wondering, shouldn't you have filed this bug against that
component, rather than gnome-terminal?

Is there anything gnome-terminal's developers could and should do to fix
this crash? As far as I understand you, it doesn't look the case to me.

Could you please re-assign this bug to the software package where the
bug actually is and whose developers thus have a chance of fixing it?

[Bug 2051371] Re: Backspace in gnome-terminal often deletes cluster

2024-01-26 Thread Egmont Koblinger
It's never the terminal emulator (whether GNOME Terminal or any other
terminal app) that decides what to print on a backspace. The only thing
it does is that it tells over the tty line that the backspace key has
been pressed.

It's the remote party, which could be the application running inside
(such as "bash", "vim" etc.), or the kernel's cooked mode handler code
(e.g. if you're running "cat") that decides what to tell to the terminal
how to update its canvas (such as e.g. retreat the cursor by one, print
a space, and retreat the cursor again -> to achieve the visual effect of
deleting the last single-cell character). The terminal emulator has no
other choice than to blindly execute these instructions and update its
canvas accordingly. (It cannot even tell if this requested display
update was in any way connected to the backspace keypress or not, nor
should it care.)

That's just the way this whole architecture looks like. You have to file
a bugreport against whichever applications where backspace doesn't work
as you'd expect it.

[Bug 2051381] [NEW] gnome-terminal-server crashed with SIGSEGV in g_utf8_pointer_to_offset()

2024-01-26 Thread Eberhard Beilharz
Public bug reported:

When I'm using ibus-keyman with the IPA (SIL) keyboard in gnome-terminal
and type n> (or just backspace after the n), gnome-terminal crashes.

The reason is that in text_input_delete_surrounding_text()
(modules/input/imwayland.c:253) before_length doesn't get checked. If we
don't have surrounding text (as in this case) cursor_pointer is NULL and
thus (cursor_pointer - before_length) results in an invalid pointer.

The other question is why we don't have surrounding text, but that's a
different problem. In any case we shouldn't crash in
text_input_delete_surrounding_text().

I believe this is a different bug from #2036647 because of the different
callstack and that we shouldn't call g_utf8_pointer_to_offset with
invalid pointers.

[Bug 1865226] Re: gdm-smartcard pam config needs to be updated for Ubuntu and installed

2024-01-26 Thread Treviño
Sorry, I missed the previous comments.

> Do I read the gnome-settings-daemon patches correctly, and this
actually just entirely drops support for auth via NSS? So the regression
potential is that if someone has set up auth via a custom system nss
database, this *will* break login for them?

Well, yes that's a regression potential that may indeed be mentioned,
it's also something that we never supported though, since that required
some extra setup in various places (write a gdm pam configuration,
create the NSS database and configure pam-pkcs11/pam_sss). But indeed it
could potentially affect someone who went through all this.

However... The SSSD side of this (lp:1905790), if one had configured a
NSS database in the canonical location, it will be migrated (using this
tool https://github.com/3v1n0/nss-database-pem-exporter).

So, it's quite a remote possibility but worth to mention in a clearer
way (it was somewhat written already).

> Unrelatedly, patches like smartcard-Use-autopointers.patch and
smartcard-manager-Use-mutex-auto-lockers-when-convenient.patch are the
sort of refactoring patches that we prefer not to see in SRUs. I don't
think they're a blocker, but they make reviewing more difficult

Let me know if I should drop them, one reason why they were added is
that they were part of the upstream changes too, and so it made easier
to ensure that we're both in the same line if problems may happen,
making easier to backport patches in future if needed.

text, the codepoints have to be deleted by emitting several backspace
keypresses. Because of the deletion of the cluster the result in gnome-
terminal is `មែរ` (U+1798 U+17c2 U+179a).

[Bug 2018539] Re: File selector extremely slow

2024-01-26 Thread Andres Hernandez
I also have this issue. The first time the file dialog opens (e.g. in
Firefox, when you right-click and do save as on an image) the dialog
appears instantly. However, each subsequent file save seems to take
exponentially longer. To the second time it's 1 second, then 2 seconds,
5 seconds, and keeps going until it's like 1 minute (at this point I
stop). Strangely, if I then attempt to open Nautilus (through the OS
menu) then Nautilus also takes 10 seconds or whatever to open. However
(with Firefox still open) if I do save as at that point, then it becomes
instant for the first save (and then continues to increase as before).
Is there any information I can provide to assist in solving this?
