Smartgit keep launching git-lfs.exe clean process for LFS track files when checkout commit

[Chee-Yang Chau]

I am using SmartGit on Windows 10.  This is the environment:

• SmartGit: version 21.1.3 #17160, installed: #17142
• Java: 11.0.8-Syntevo+0
• Git: git version 2.34.1.windows.1
• Git LFS: git-lfs/3.0.2 (GitHub; windows amd64; go 1.17.2)

I create a local repository and define commits as follow:

1. Commit 1: git lfs install, git lfs track "*.obj"
2. Commit 2: push 100 *.obj files
3. Commit 3: push another 100 *.obj files

Now my HEAD is commit 3.

Scenario A

• Log windows is on
• Working Tree Windows is off
• Low Level Properties: log.workingTreeState=False
• Outcome: Checkout Commit 2 or Commit 3 is smooth, just like how I use git console command.

Scenario B

• Log windows is on
• Working Tree Windows is on
• Low Level Properties: log.workingTreeState=True
• Outcome: Checkout commit 2 or commit 3, the SmartGit show Please wait... and freeze  the window.

In Scenario B, I notice SmartGit keep launching git-lfs.exe clean for each *.obj files.  This behavior is painfully slow.  If I have thousand of LFS objects, perform such checkout is takes a lot of time.  This only happen to SmartGit, so far it doesn't happen to `git` console operation.

Can you please capture periodical thread dumps and send to smar...@syntevo.com?

https://docs.syntevo.com/SmartGit/HowTos/Periodical-Thread-Dumps.html

It would be really helpful if you can set up a test repository on GitHub for which the problem becomes reproducible for us (I'm on Windows 10, too).

Hi,

I have created a git repository in Github to show the issue:  https://github.com/ccy/SmartGit-LFS-Test

There is a commit to store the Periodical Thread dump log to show the git-lfs.exe clean issue too.

Thanks! I could reproduce the problem now. Please give the latest build 17170 a try and add following line to smartgit.properties (in the Settings directory) before restarting:

smartgit.status.forceUpdateIndexForLfsRepositories=true

Does this resolve the problem for you? If not, please send compressed logs/logs.txt.0 directly to smar...@syntevo.com .

Hi,

After update to build 17170, there is another case where the git-lfs.exe clean processes issue happen.

1. Clone the repository: https://github.com/ccy/SmartGit-LFS-Test
2. Checkout commit obj files #2
   
3. Cherry pick obj files #1
   
4. git-lfs.exe clean happen again

Thanks for reporting! For conflicts, unfortunately there is no easy fix here, hence I have scheduled this for 22.1 (SG-15071).
