Description Patrick Silva 2017-09-15 17:21:36 UTC 
k3b-git installed on Arch from AUR...

create a dvd-video/data project, add some files to it
click "burn" button, check "only create image", click "start" button
Progress bars show no progress.
Comment 1 Leslie Zhai 2017-09-25 01:44:22 UTC 
My question is: failed to save a project to an ISO file? if not failed I need to check DataJob.
Comment 2 Patrick Silva 2017-09-25 02:26:26 UTC 
ISO file is successfully created.
Comment 3 Leslie Zhai 2017-09-25 02:47:34 UTC 
then how to reproduce the issue?


mkisofs
-----------------------
/usr/bin/genisoimage: No such file or directory. Failed to open VIDEO_TS.IFO
/usr/bin/genisoimage: Can't open VMG info for '/tmp/k3bVideoDvd20vsLE/'.
/usr/bin/genisoimage: Unable to parse DVD-Video structures.
/usr/bin/genisoimage: Could not find correct 'VIDEO_TS' directory.
Possible reasons:
  - VIDEO_TS subdirectory was not found on specified location
  - VIDEO_TS has invalid contents

mkisofs calculate size command:
-----------------------
/usr/bin/genisoimage -gui -graft-points -print-size -quiet -volid untitled -volset  -appid K3B THE CD KREATOR (C) 1998-2017 SEBASTIAN TRUEG, MICHAL MALEK AND LESLIE ZHAI -publisher  -preparer  -sysid LINUX -volset-size 1 -volset-seqno 1 -sort /tmp/k3b.h10397 -no-cache-inodes -udf -iso-level 1 -path-list /tmp/k3b.X10397 -dvd-video -f /tmp/k3bVideoDvd20vsLE


I have no idea how to create COPYRIGHT *legal* DVD image...
Comment 4 Patrick Silva 2017-09-25 02:56:36 UTC 
create a data project
add some files to it
click "burn" button
check "only create image"
click "start" button
Comment 5 Leslie Zhai 2017-09-25 03:06:38 UTC 
but it updates the percentage for me:

so the testcase 'create a data project' can *not* reproduce the issue.
Comment 6 Patrick Silva 2017-09-25 18:46:16 UTC 
On Arch the progess bars dont work with k3b-git from AUR nor with k3b 17.08.1 from oficial repositories.
With k3b 17.08.1 I can test only data project, it does not create dvd-video ISO because a bug not fixed in this release.

I cant reproduce this bug on neon dev unstable.
Comment 7 Patrick Silva 2017-11-18 02:40:58 UTC 
k3b 17.12 beta has the same bug on Arch Linux.
Comment 8 Patrick Silva 2017-12-05 16:19:20 UTC 
My Arch Linux runs k3b 17.08.3, cdrtools 3.02a07-2 and mkisofs 3.2a07.

I tested other distros...

kaos running k3b 17.08.2, cdrtools-3.02a07-1 and mkisofs 3.2a07: progress bars don't work.

gecko (based on opensuse tumbleweed) running k3b 17.08.2, cdrkit-cdrtools-compact and mkisofs 1.1.11: progress bars work.
But progress bars stopped working after I replaced cdrkit-cdrtools-compact and mkisofs 1.1.11 with cdrtools 3.02-a07-2.3 and mkisofs 3.2a07.

neon user edition running k3b 17.11.80 and mkisofs 1.1.11: progress bars work.
But progress bars stopped working after I replaced mkisofs 1.1.11 with mkisofs 3.2a07.

On Arch when I click on "show debugging output" button after ISO creation, K3b log shows progress information.
But the progress bars in K3b GUI show no progress.

Seems there is some problem between K3b and mkisofs 3.2a07.
Comment 9 Leslie Zhai 2017-12-06 03:05:18 UTC 
Sorry I do not use ArchLinux any more, I am using Fedora for ARMmbed development, because there are more RedHat engineers working for GNU and LLVM Toolchain, and I can not reproduce this issue for Fedora.

Comment 13 Thomas Schmitt 2017-12-07 08:49:37 UTC 
Hi,

the function to read the progress percentage, parseMkisofsProgress
in libk3b/projects/datacd/k3bmkisofshandler.cpp, obviously expects that
no other text is written before the percent number. Like in

    1.29% done, estimate finish Mon Sep 25 11:04:34 2017

This would not work with xorrisofs messages

  xorriso : UPDATE :  0.54% done, estimate finish Wed Dec 06 14:27:33 2017
  
@Dr. Chapatin:
Can you show a progress line from mkisofs 3.2a07 (or any other that causes
the lack of progrss bar) ?
It should be in the K3B log or may get produced by a shell terminal run like

  mkisofs -v -o /dev/null /...some.big.directory.tree...


> $ rpm -qf /usr/bin/mkisofs
> genisoimage-1.1.11-31.fc24.x86_64
> xorriso-1.4.8-1.fc25.x86_64

I actually discourage distros to install xorriso as "mkisofs". That would
rather be a decision of the end user after considering all desired use cases.

But if Fedora does this, then K3B should better prepare for decoding xorrisofs
pacifier lines.

Have a nice day :)

Hi Thomas
This line appears in K3b log
  0,08% done, estimate finish Thu Dec  7 07:05:20 2017
Comment 15 Thomas Schmitt 2017-12-07 09:49:41 UTC 
Hi,

>   0,08% done, estimate finish Thu Dec  7 07:05:20 2017

I guess the comma instead of the decimal point is to blame.
It probably stems from internationalization (i18n) which could be a new
feature in mkisofs-3.x.

One could test the theory by testing whether

   QString perStr = "0,08";
   bool ok;

   double p = perStr.toDouble( &ok );

yields (ok == false) or 0.0 as resulting number.
(Sorry, i don't have enough KDE/Qt for testing this.)

The reverse test could be to set the environment for english language
before starting K3B:

  export LANGUAGE=en_US:en
  /usr/bin/k3b

mkisofs should then emit decimal points rather than commas.
I assume that mkisofs uses GNU gettext which would use that variable.
See https://www.gnu.org/software/gettext/manual/html_node/Locale-Environment-Variables.html


If the theory is right, then K3B needs internationalization for its own
number decoding, or it needs to set mkisofs to english language and number
formats.
(xorriso is intentionally not using i18n. It is painful to analyse the
 output of the own program when all words are replaced by a language which
 i do not know.)

Have a nice day :)

Comment 16 Patrick Silva 2017-12-07 10:06:03 UTC 
You are right Thomas.
I changed "Formats" to en-US in KDE regional settings on Arch Linux, progress bars are working now.
Comment 17 Thomas Schmitt 2017-12-07 10:38:29 UTC 
Hi,

> I changed "Formats" to en-US in KDE regional settings

(I wonder how it looks if you choose Inuit or Samaritan Aramaic.)

> progress bars are working now.

So the cheapest, but possibly incomplete, fix would be to replace commas
by decimal points in
  int K3b::MkisofsHandler::parseMkisofsProgress( const QString& line )
of libk3b/projects/datacd/k3bmkisofshandler.cpp before interpreting the
number by
    double p = perStr.toDouble( &ok );

If one wants to prepare for xorrisofs, then one should submit to the
converter function .toDouble() the text beginning at its first digit or
decimal point.

A complete solution for mkisofs would be either to decode numbers with i18n 
in mind, or to prevent i18n of mkisofs. The latter seems to be the better 
solution in respect to preventing other i18n surprises and in order to keep 
the debugging output of mkisofs readable for international developers.

Have a nice day :)
