User Agent: Mozilla/5.0 (X11; Linux i686; rv:39.0) Gecko/20100101 Firefox/39.0 Iceweasel/39.0
Build ID: 20150703101329

Steps to reproduce:

1) Open a page with long title, example: http://детский-мир.net/%D0%A0%D0%B0%D1%81%D0%BA%D1%80%D0%B0%D1%81%D0%BA%D0%B8/7932.htm 
2) Try to print it using CUPS printer



Actual results:

Firefox gives no error, nut no page printed. CUPS log (/var/log/cups/error_log) contain following error:

E [18/Jul/2015:16:20:40 +0300] [Client 17] Returning IPP client-error-attributes-or-values-not-supported for Print-Job (ipp://localhost:631/printers/HP_LaserJet_1018) from localhost


Expected results:

Page should be printed.
I find similar bug in Thunderbird (https://bugzilla.mozilla.org/show_bug.cgi?id=917340) - both bugs related to a long print jobname which is constructed from page title. If I reduce title length using developers tools - firefox will successfully print this page.
The same problem when the title-tag is empty and Firefox automatically uses the URL (in my case the length was 309).
By using firebug (or developer tools) and adding a short title inside the header-section, the Problem was solved.

https://tools.ietf.org/html/rfc2911
4.1.2 'name'

   This syntax type is used for user-friendly strings, such as a Printer
   name, that, for humans, are more meaningful than identifiers. Names
   are never translated from one natural language to another. The
   'name' attribute syntax is essentially the same as 'text', including
   the REQUIRED support of UTF-8 except that the sequence of characters
   is limited so that its encoded form MUST NOT exceed 255 (MAX) octets.

   Also like 'text', 'name' is really an abbreviated notation for either
   'nameWithoutLanguage' or 'nameWithLanguage'. That is, all IPP
   objects and clients MUST support both the 'nameWithoutLanguage' and
   'nameWithLanguage' attribute syntaxes. However, in actual usage and
html file for reproducing problem
I´m not sure if this belongs here but the same problem exist also in Thunderbird see here:

https://bugzilla.mozilla.org/show_bug.cgi?id=917340
This bug still exists in FF47, I'm currently updating the system and will confirm it for FF49.

The solution seems to be according to the RFC above to truncate the name field to 255 characters.
Not only is Unix, but macOS also has the same problem.
The IPP disallow over 256 characters for job-title[1], but Gecko passes the long title.
Blink and Webkit cuts this title length[2][3][4].

Note:
1) Gecko cuts 255 lengths on windows[5].
2) GNOME Evince has the same problem(i.e. we can't print long title via IPP). I think that Evince should cut title as well.

Oh, this is skia version.

Windows is here(Cairo):
https://dxr.mozilla.org/mozilla-central/rev/f9a5e9ed62103c84e4cde915f4d08f1ce71be83e/gfx/thebes/PrintTargetWindows.cpp#66-70

In any way, windows already shorten the title.
Thank you for the links.

There are two bugs reported here, on Linux:

1) The failure to print.

2) The lack of any error message.

The first bug is a problem with the GTK cups print backend, where is generates
the IPP name.  (Gecko uses gtk_print_job_new(), for which the title parameter
is not necessarily associated with IPP and has no length restrictions in fixed
versions.)
The initial report https://bugzilla.gnome.org/show_bug.cgi?id=755988
was fixed in
https://git.gnome.org/browse/gtk+/log/gtk/gtkprintoperation.c?h=3.18.2
The fixed was moved to the cups implementation for

Have you reproduced on MacOS?
Is there an error message?

https://developer.apple.com/documentation/applicationservices/1460149-pmprintsettingssetjobname?language=objc
doesn't say anything about IPP.

> Note:

https://msdn.microsoft.com/en-us/library/windows/desktop/aa365247(v=vs.85).aspx
indicates that Gecko is cutting to 259 octets on WINNT.

That's the GTK cups print backend bug.

Bug 1185236 - Shorten print job name when GTK version is older than 3.18.2.

https://reviewboard.mozilla.org/r/178650/#review184350

I'm happy to take a workaround for older GTK versions, but please restrict the
workaround to those versions, and please don't split UTF-8 multi-byte
characters as this has the potential to confuse other consumers.
GLib provides g_utf8_find_prev_char(), which could be useful.
I don't know whether or not Gecko has a similar utility.

We should get someone else to review a Cocoa change, so please do that in a
separate patch.

Yes, I got the following messages in cups error message with CUPS debug mode:

As far as I can see in the open radar, there are not same bugs.

Oh, Windows has the same problem as well. I can reproduce via ipp print.
I think that we should cut job-name length on windows. I confirmed prevent this phenomenon if we will cut job-name length.

Using Length of the C string with the UTF16 string doesn't look right.

MAX_IPP_JOB_NAME_LENGTH would be a little clearer.
If this won't be needed outside the .cpp file, then please move the define to the .cpp file.

Please name this AdjustPrintJobNameForIPP or AdjustJobNameForIPP.

NS_ConvertUTF16toUTF8 is a class, and so this would be

NS_ConvertUTF16toUTF8 title(aJobName);

That looks odd to me though, and so I suggest

nsCString title;
AppendUTF16toUTF8(aJobName, title);

Another option is:

CopyUTF16toUTF8(aJobName, aAdjustedJobName);

RewindToPriorUTF8Codepoint() should be a bit more efficient here, and may even be a little simpler.

::: gfx/thebes/PrintTarget.cpp:175
(Diff revision 1)
> +    if (!IsUTF8(title)) {

As title is from a conversion to UTF8, it should be safe to assume that it is valid UTF8, and so this path is not necessary.

Either "Print job names exceeding 255 bytes are safe with GTK version 3.18.2 or newer."

CopyUTF16toUTF8(aTitle, mTitle)

And the Truncate() above can be removed.

|aTitle| was a UTF16 string, and so I assume UniChar is similar.  |title| is a C string, i.e. bytes.
It needs to be converted back to UTF16 before casting its data to UniChar.

I assume the WINNT port would benefit from something similar, and so I'd suggest two static methods on PrintTarget():

AdjustPrintJobNameForIPP(nsCString& aJobName);
AdjustPrintJobNameForIPP(nsString& aJobName);

The latter would use the former.

Please remove the (uint32_t) reinterpret_cast as an explicit cast is not necessary.

A second parameter of RewindToPriorUTF8Codepoint() defined as UnsignedT, So I think we need this cast.

Ah, thanks.  How about replacing "3" with "3U", so that the result of the expression is unsigned even without the cast?
