git lfs throws "expected OID error"

Hello, Everyone!

I using Microsoft Windows to building ParaView in version5.13.0

I am getting the following error when trying to clone the repository

Error downloading object: data/README.md (b30a14a): Smudge error: Error downloading data/README.md (b30a14a308f64c6fc2
969e2b959d79dacdc5affda1d1c0e24f8e176304147146): expected OID b30a14a308f64c6fc2969e2b959d79dacdc5affda1d1c0e24f8e1763

it seems as if the repo is corrupt, Can you fix it?

I am using git version 2.51.0.windows.2 and git-lfs/3.7.0 (GitHub; windows amd64; go 1.24.4; git 92dddf56)

the processing of cloning the repo as follow:

cd C:
mkdir pv
cd pv
git clone https://gitlab.kitware.com/paraview/paraview.git
mv paraview pv
mkdir pvb
cd pv
git checkout v5.13.0

Seems to be related to the new security we added on our gitlab.

Can you try clone this repo directly: https://gitlab.kitware.com/vtk/vtk-m ?

no, it’s failed for cloning vtk-m repo directly

Hi, Monsieur Mathieu.

I’m not sure when you will be able to resolve this issue. In the case of a failed git clone, I want to compile and build ParaView on Windows. Based on the following messages, can I download the corresponding submodule archives (VTK, VisItBridge, vtkicet, vtkqttesting) from GitLab, extract the submodules to the corresponding paths, i.e., the ‘path’ in the submodule, and then build according to the method described at ParaView/Documentation/dev/build.md at master · Kitware/ParaView · GitHub?

But the problem I’m concerned about is that I don’t know which commits of these submodules to download.

$ cat ./.gitmodules
[submodule "VTK"]
        path = VTK
        url = https://gitlab.kitware.com/vtk/vtk.git
        branch = paraview/release
[submodule "Utilities/VisItBridge"]
        path = Utilities/VisItBridge
        url = https://gitlab.kitware.com/paraview/visitbridge.git
[submodule "ThirdParty/IceT/vtkicet"]
        path = ThirdParty/IceT/vtkicet
        url = https://gitlab.kitware.com/paraview/icet.git
        branch = for/paraview
[submodule "ThirdParty/QtTesting/vtkqttesting"]
        path = ThirdParty/QtTesting/vtkqttesting
        url = https://gitlab.kitware.com/paraview/qttesting.git
7

You should be able to clone ParaView master without issues, as the git lfs project is gone.

Okay, Thank you for your reply!

I try clone the vtk-m repo directly again，But it seems that the previous problem still exists

and It also throws “expected OID error” after running command git submodule update --init --recursive

vtk-m is not a submodule anymore of ParaView, this is what i mean by the fact that you can clone ParaView master and submodules without issues.

10

Okay, I see, Thank you!

In Paraview’s master branch, I can run $ git submodule update --init --recursive without any problems. The relevant information is as follows. May I ask if this means that I have successfully cloned paraview master?

If I want to build ParaView v5.13.0 in windows, I have to checkout branch to tag v5.13.0
and In this branch, It still throws “expected OID error”

This means, I can only develop paraview based on the master branch. If I want to develop based on Tagv5.13.0, I have no way.

If I want to develop based on Tagv5.13.0, I have no way.

If you want to update submoduule in v5.13.0, you need to remove vtk-m for the .gitsubmodules files

12

Alternatively you can also:

export GIT_LFS_SKIP_SMUDGE=1

13

you mean .gitmodule file,
but in branch v5.13.0, there is not exist the URL of vtk-m in the .gitmodule file

$ cat ./.gitmodules
[submodule "VTK"]
        path = VTK
        url = https://gitlab.kitware.com/vtk/vtk.git
        branch = paraview/release
[submodule "Utilities/VisItBridge"]
        path = Utilities/VisItBridge
        url = https://gitlab.kitware.com/paraview/visitbridge.git
[submodule "ThirdParty/IceT/vtkicet"]
        path = ThirdParty/IceT/vtkicet
        url = https://gitlab.kitware.com/paraview/icet.git
        branch = for/paraview
[submodule "ThirdParty/QtTesting/vtkqttesting"]
        path = ThirdParty/QtTesting/vtkqttesting
        url = https://gitlab.kitware.com/paraview/qttesting.git
14

Indeed, its in VTK/.gitmodules

15

This is probably the easiest solution. You don’t have to monkey with the git configuration files, and skipping the LFS files should be OK even if you build VTK-m as part of ParaView.

yes, I run git lfs install --skip-smudge firstly, and than clone the submodule, It’s also working.
