kdiff3 no longer works for me

Hello All,

I use kdiff3 quite frequently, usually in combination with git (git difftool -t kdiff3). This has stopped working
for me recently, presumably after an archlinux update. It is not just in combination with git. Also attempting
to diff two random text files doing kdiff3 FILE1 FILE2 fails. It opens, does not display the contents for the
file but instead shows an error window saying 'Opening of these files failed: <name of file> Opening
<name of file> failed. Unknown error'.

Anyone any idea?

Kind Regards,
Chris

Re: kdiff3 no longer works for me

Worksforme™

Your system is up to date/no partial updates? Particularly kio is going to be relevant. Do you see any other message from a terminal run?

Re: kdiff3 no longer works for me

Hello V1del,

Yes, I update the system quite regularly (pacman -Syu). Just did an update to check and I still have the problem.
kio is at 6.1.0. Terminal does not say anything particular.

[chrisd@chrispc ~]$ kdiff3 bla TODO
org.kde.kdiff3: Loading A:  "/home/chrisd/bla"
org.kde.kdiff3: Loading B:  "/home/chrisd/TODO"

I also tried on another PC and there kdiff3 works, so it does seem to be something particular about this
machine.

O well, it is not that important, I can also just kompare.

Kind Regards,
Chris

Re: kdiff3 no longer works for me

error window saying 'Opening of these files failed: <name of file> Opening <name of file> failed. Unknown error'.

strace -o /tmp/kdiff.strace -f -tt kdiff3 bla TODO

Then check/upload the strace.

Re: kdiff3 no longer works for me

Hello Seth,

I uploaded the strace: http://0x0.st/X8K8.txt .

Note that after the error appeared I pressed Ctrl-C to end kdiff3. This is also visible at the
end of the strace.

Kind Regards,
Chris

and assuming the tail of that is to show you the error dialog, this seems a complete false positive.

The file contents seem to be vastly different, have you tried comparing two files where one is actually just a slight deviation of the other?

Re: kdiff3 no longer works for me

Hello Seth,

Yes, usually I use kdiff3 on files that only differ in a few places. But I just retried that again. It also
displays the error and not the files in that case.

The whole thing sounds like it reads the data correctly but for some reason, incorrectly, decides
that it failed reading the data and therefore displays the error instead of the content of the files.

Kind Regards,
Chris

not sure what a diff needs a config for, but try to move that away…

Re: kdiff3 no longer works for me

------------------ EDIT 2024-06-19 14:33 UTC ------------------

The issue is still happening occasionally with longer filenames / paths, same symptomatic as before. But I can no longer get it to reproduce with kdiff3 /tmp/a /tmp/b /tmp/c

Error is no longer occurring all the time. Some diffs work fine without an error, some don't.

------------------ EDIT 2024-06-19 14:30 UTC ------------------
*just* as I finished testing this, I was doing a system upgrade (apt-upgrade) after seeing new packages when installing strace - and with today's system upgrade, the issue is finally gone and kdiff3 works as intended again.

Here is my relevant /var/log/apt/history.log: http://0x0.st/XT2a.log

As you can see, the latest system update was only 2 days old, so that today's update (that fixed the issue? Or was it the system reboot I did after deleting .config/kdiff3rc?) only installed relatively few changes - but it did bring a kernel update to version 6.8.12:

$ uname -a
Linux computer 6.8.12-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.8.12-1 (2024-05-31) x86_64 GNU/Linux

The version of kdiff3 is unchanged at 1.11.1 (64 bit)

------------------ ORIGINAL POST BELOW ------------------

I would like to add a "can reproduce" to this issue - I am having the exact(?) same problem on debian since my upgrade to trixie a few months ago

$ uname -a
Linux computer 6.7.12-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.7.12-1 (2024-04-24) x86_64 GNU/Linux
$ kdiff3 --version
kdiff3 1.11.1 (64 bit)

Prior to submitting this report, and prior to getting the reported results, I deleted ~/.config/kdiff3rc

I performed an strace as recommended by seth 2024-05-07 08:29:42

strace -o /tmp/kdiff.strace -f -tt kdiff3 a b c

Resulting in this tracefile: http://0x0.st/XTew.strace

$ kdiff3 a b c

starts kdiff3 with the error message:

File open error -- KDiff3
Opening of these files failed:

- /tmp/a
Opening /tmp/a failed. Uknown error
- /tmp/b
Opening /tmp/b failed. Uknown error

Information I can add to the original issue description:
The error about file /tmp/a is not always reproducible, most of the time it only complains about /tmp/b.
I have never seen the error mentioning file /tmp/c.

Confirming the error with "OK" opens "Dialog -- KDiff3" which allows to select files to open and pre-selects the command line arguments with full path
A (Base):        /tmp/a
B:                   /tmp/b
C: (Optional): /tmp/c

Confirming that dialog unchanged with "OK" succeeds in opening the three files in kdiff3 as expected.

Invoking kdiff3 with absolute paths like so

kdiff3 /tmp/a /tmp/b /tmp/c

exhibits the exact same error.

locale looks unsupicious, but kdiff3rc still shows up in the strace?

If by kdiff3rc you refer to the file in .config - it appears to get re-created (as I would expect) on every start of kdiff3?

Is there a specific bug you wanted to point me to, or was the => arrow suggesting I should open a bug report?

Cheers,

Re: kdiff3 no longer works for me

I should open a bug report

There's no indication in either strace that "Opening /tmp/a failed. Uknown error" so there there's a bug in kdiff's logic that has to be identified and fixed.

One of the next days I'll try to open a bug report - I've been quite busy & just wanted to add something to the analysis here.

Re: kdiff3 no longer works for me

Still happening to me, but I add that when trying to open the very same files that failed in the GUI, they open correctly.

Re: kdiff3 no longer works for me

1.11.5 contains a fix for one cause of this error. This has was released within the last week. Still getting reports of this at least on windows. Its not imminently clear my the gui doesn't trigger the issue. I have been test with direct command line use to see there's another reproducible  bug there.
