Directory diff seg faults

[astromme]

SlickEdit Pro 2023 (v28.0.0.2 64-bit Qt4) on Ubuntu 22.04.2 LTS.

I configure git to use vsdiff as its diff and directory diff tool.  When I try to do a diff between commits, vsdiff seg faults.

This also seg faults on Beta 1, but not Slickedit 2021.

[diff]
    tool = vsdiff
    submodule = log
    mnemonicprefix = true
[difftool]
    prompt = false
[difftool "vsdiff"]
    cmd = "~/bin/vsdiff" "$LOCAL" "$REMOTE"

!"git difftool --dir-diff"

I will look into this.

[Dan]

 I haven't been able to get it to run vsdiff so far.  I seem to remember that there is another setting elsewhere to tweak (in another file), or an environment variable?

[astromme]

I don't have anything else in my environment related to it..

I do have this in my .gitconfig:


[alias]
    dd = !"git difftool --dir-diff"


The above instead of the partial line starting with the ! in the initial post.

Dan, make sure you specify a file that is modified. Otherwise, it won't even try to run your configured diff tool.

Code: [Select]

git difftool readme.html
git dd

where readme.html is modified.

This works fine for me. No crash. I tested beta 1 and beta 2. I tested Linux Mint 21 and Ubuntu 22.

Does it crash if you run git difftool on a single file?

[astromme]

Does it crash if you run git difftool on a single file?

It does not.  I tried running

Code: [Select]

git difftool <commit> <file> and it didn't crash.

I also tried running

Code: [Select]

git difftool <commit> WITHOUT a file, and it didn't crash; it just shows vsdiff as a single window with the first file.. when I exit that diff, it opens another vsdiff window with the next file, etc.

When I run

Code: [Select]

git difftool --dir-diff <commit> a window titled "Multi-File Diff Finding Files" with the temp directories briefly opens with no content (just a gray background) then closes after a second, and the shell says

Code: [Select]

Segmentation fault (core dumped)
Previous working behavior is to open the multifile diff window that shows the tree.

Sorry it took a while to reply.

When you say <commit> you're giving the SHA hash for the commit?  The full one, or an abbreviation?  I have tried this, and I still don't get a crash.

I'm using the Qt4 version of Beta 2. Is there anything about your system that you could tell us that might help?

Generally the short version, or a short version.

It's more or less vanilla Ubuntu..

One thing that may or may not be relevant - I wanted to create a single directory link to switch between versions of Slickedit when I install a new one, but sometimes I run into difficulties..

Code: [Select]

stromme@WORK:~$ ls -la ~/bin

lrwxrwxrwx  1 stromme stromme   25 Aug 10 16:56 vsmerge -> slickedit-dir/bin/vsmerge
I tried this, but ran into some issues where vs didn't want to start.

Then I tried replacing the link from vs to slickedit-dir to this script:

Code: [Select]

#!/bin/bash
$(dirname "$0")/slickedit-dir/bin/vsbut that didn't really work right either, so I gave up and just did this:

Code: [Select]

vs -> /opt/slickedit-pro2023beta2/bin/vs
Could these links be causing weird behavior?

The main behavior I want is to type "vs somefile" from any shell anywhere and have it open in my Slickedit instance.

[Clark]

Using a symbolic link (i.e. 'ln -s /opt/slickedit-pro2023beta2/bin/vs vs") will have no effect on this. "bin/vs" is a script which resolves symbolic links. Take a look at the script source and you'll see the loop which resolves symbolic links.

I built an installer with added debug in vsdiff that hopefully will tell us something. Please install and test with this debug vsdiff.

vsdiff may be crashing when diffing a particular file. If so, this test will let us know which file. I removed the theading (this uses only 1 thread), so that the debug info will be much easier to figure out.

The debug will be written to /home/<username>/.slickedit/28.0.0/logs/vs.log

After vsdiff crashes, dump the contents of vs.log. If it looks like it crashed on a particular file. Run it again and see if it still crashes on the same file. Keep me posted.

v28 beta 2 installer with debug for vsdiff:

https://support.slickedit.com/outbound/2800/se_28000002_linux64qt5_beta2_vsdiff_debug1.tar.gz

[astromme]

Incidentally, I switched to qt5 version (via softlinks) we talked about here: https://community.slickedit.com/index.php/topic,19267.msg76904.html#msg76904 and it doesn't crash.. I switched back to to the "original" 2023 beta 2 and it crashes again.

Would you still like me to try the debug version you created?

[Clark]

Not sure I completely follow your post.

Does the Qt 5 v28 beta 2 vsdiff work for you?

[astromme]

Yes.

SlickEdit Pro 2023 (v28.0.0.2 64-bit Qt5) vsdiff works fine.

SlickEdit Pro 2023 (v28.0.0.2 64-bit Qt4) vsdiff crashes as described earlier.

[Clark]

No need to test this installer. Glad Qt 5 vsdiff works!
