Hi Martin-Éric,

I've seen your decision about becoming a DM in the recent changelog
update. Congratulations and thanks for taking over the responsibility!


However, I'd like to challenge your decision of closing this bug:

On 2025-03-11 19:28, Martin-Éric Racine wrote:

Since this is merely a question of preferred behavior that can be
easily configured by changing the value for TitlePref, I'm closing
this bug.

since I'm quite confident that there *is* a bug if one wants to use TitlePref=0. Which I happen to do.


As I mentioned already in my update #40 [1] (with different email
address back then), the following block from cups-pdf.c

------------------------------ snip ------------------------------
if (sscanf(buffer, "%%%%Title: %"TBUFSIZE"c", title)==1) {
log_event(CPDEBUG, "found title in ps code: %s", title);
is_title=1;
}
------------------------------ snip ------------------------------

is buggy since sscanf does not zero-terminate the string.

I can provide a patch for that if you see any chances to get this
incorporated.

Thanks again

Jens

Sounds good, thanks for the offer.

Two follow-up questions:

- The upstream of cups-pdf seems to be inactive for quite some
time already, correct? So fixing this issue directly in
Debian is the best we could hope for, correct?

- I haven't yet provided patches to a Debian project. Would
the description found, for example, here:

https://raphaelhertzog.com/2011/07/04/how-to-prepare-patches-for-debian-packages/

be OK for you and cups-pdf? If you have a more recent or
more appropriate description, please let me know.

Thanks

Jens

Upstream became a father a couple of years ago, and he has a busy job
in a medical research lab. His time outside of that has become
extremely limited.

Yes or just follow what dpkg-source says when it notifies you that you
have modified the source and generates the patch template for you.

Here is my patch, then. Plus a small postscript test document with
an extra short title to demonstrate the difference in file name without
my patch (generating job 29):

Thanks. I'm curious to see what upstream thinks of this first. I just
pinged him.

Any reaction on that ping of yours? It has been a while now.
But OTOH there has has been even an upstream release just after
your last reply to this bug, so there might still be hope!

Thanks

None, other than a short e-mail informing me of that small release incorporating only the Ghostscript patch and telling me that he might
find the time to address other pending issues later this year.

Thanks. Will wait patiently, then.
