AutoColumnize throws an Exception with multiple files if no bookmarks are found

[Hirogen]

Drag and Dropped 2 logfiles in the empty (new instance) of logexpert
This did happen a few Times, due to an important log analysis I had to switch to 1.6.13, after that I couldn't reproduce the error :/

The Exception in the bottom have been thrown (logexpert needed to be closed shutdown), after restarting the same problem.

• LogExpert Version: 1.6.14
• Windows Version: yes
• Network: 2 files from network
• AutoColumnizer was chosen automatically
• Can only happen with Version 1.6.14+, AutoColumnizer was added!
• Size of the files
  1.) 350mb
  2.) 250mb

Feature

AutoColumnicer

IMPORTANT NOTE:
Filename + Folders was about 244 Characters long!

The method or operation is not implemented.

Luckily Logexpert logs its own logfile in the app-data of the user following exception was inserted there:

Workaround could be to set the default columnizer again to "Default (single line)" in the Settings under Tools -> Settings

Was one or both files already opened and did you create some bookmarks for this? Currently I'm not able to reproduce this error. Maybe it could help to delete the "session" directory located here
<user dir>\Documents\LogExpert\. Did you use MultiFile or Single File?

[Hirogen]

Currently trying to reproduce the exception, did It once today, but can not figure out what the problem seems to be.

Last time I had 5 Instances open and the same exception occurred.

Seems to happen, if a Bookmark is created in one instance and somehow the new instance trys to find the bookmark in the new logfile.

Will be testing a little bit more. Hopefully I can find a way to easily recreate it.

[Hirogen]

I could finally reproduce it, reliable.

5 Logfiles in Folder structure
Drag and Drop 5 Folders (with the logfiles) into logexpert => will not open
Close the first with "strg + w" / "ctrl + w"

Ok, I think I'm able to reproduce your error.

• create 5 folder with one log file in it
• drag and drop the created 5 folder
• close one tab with "ctrl + w"
• -> Exception

I understand this is a error, but is this a use case? Or do I miss a point?

[miltob]

Hi guys,

I am able to reproduce it. I'll working on this if you don't mind.

[zarunbal]

Feel free, I really appreciate this help!

[miltob]

So far I find it's easy to reproduce this problem in 1.6.14 but not in latest master or development branch.

To reproduce this problem on 1.6.14:

1. Create two files.
2. First file with name: 0123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901.log.txt
3. Second file with name: 012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890.log.lll
4. Open both files with LogExpert.
5. Close LogExpert.
6. Change the postfix of both file to something different.
7. Open LogExpert again.
8. Click the first tab.
9. Get exception above and LogExpert crashes.

I believe this problem has been fixed in 1.7.0. @Hirogen please try it here https://github.com/zarunbal/LogExpert/releases/tag/v1.7.0

However, I'll submit a refactor anyway.

[Hirogen]

I will test it on monday

[Hirogen]

Ok, I think I'm able to reproduce your error.
* create 5 folder with one log file in it
* drag and drop the created 5 folder
* close one tab with "ctrl + w"
* -> Exception
I understand this is a error, but is this a use case? Or do I miss a point?

So with 1.7.0 i couldn't recreate the exception, currently It seems to be fixed.

Regarding the use case. I work a lot with big logfiles in different folders, we have between 1 and 10 Workstations that generate Logfiles and sometimes I need to check 3-4, so I just drag and drop the logfiles in the window and sometimes I forget that files in a folder structure are not opened (I create a separate issue for that)

[zarunbal]

Thank you @Hirogen for the testing!
