cloning a repo with git-lfs support generates NumberFormatException: For input string: "t" [message #1837374]

Hi Folks,

ENV:
- OSX 11.1 (Big Sur)
- eclipse
Eclipse IDE for Enterprise Java Developers (includes Incubating components)

Version: 2020-12 (4.18.0)
Build id: 20201210-1552

- java
openjdk version "15.0.2" 2021-01-19
OpenJDK Runtime Environment AdoptOpenJDK (build 15.0.2+7)
OpenJDK 64-Bit Server VM AdoptOpenJDK (build 15.0.2+7, mixed mode, sharing)

Since upgrading I've needed to re-enable git support, namely git lfs. In the past I had no luck getting the "Enable git-lfs support" button to "enable" but was able to get around it by adding a path variable so eclipse could find git-lfs. But now it seems like egit/jgit support for this works, I can click the enable button and it tells me support has been enabled.

The issue I'm having is when I try and clone a repository which requires git-lfs, I get the following stack:

!ENTRY org.eclipse.egit.ui 4 0 2021-01-28 13:16:15.767
!MESSAGE For input string: "t"
!STACK 0

I'd prefer to use egit/jgit for all of this, but if I have to I guess I could disable that and go back to the system binaries but I'd prefer not to.

Any help is most appreciated.

Looks like .gitattributes is set up wrongly, and the LFS filter gets run on a non-LFS object? Is the repo being clond public, so that we could try to reproduce?

I've opened bug 570744 for this. But all the same I wonder what .gitattributes says.

Hi - thanks for responding.
The repo is not public, but the .gitattributes file shows this:

* text=auto

# Text formats
*.txt text
*.sh text

# Binary Formats
*.tgz binary
*.rpm binary

*.tar filter=lfs diff=lfs merge=lfs -text

I should also note that I am getting around this by running git from the command line and it's not having any issues with lfs, etc.

Is there any tar-file in the repo that is not a LFS pointer? Possibly one that was committed before the repo moved to using git-lfs? (I suspect that tar file contains C sources.)

That might explain the error.

Not sure, but from looking at the git-lfs sources it seems to me that standard git-lfs would pass through such an already committed tar file normally. (Might become a LFS pointer/file if checked-in again, though). JGit's internal SmudgeFilter doesn't appear to do so.

When I clone the repo on the commandline, I get this (obviously obfuscated in a silly way but you get the idea):

Encountered 1 file(s) that should have been pointers, but weren't:
	misc/foo/filename.tar

Just the one file.

That file causes your trouble. Is the file checked out correctly with command-line git? I.e., not empty, and you can actually untar it? And please satisfy my curiosity: does it contain C sources? :-)

Yes, it checks out fine. I can untar it, and it's C sources. :)

Great, thanks. Opened another bug 570758 for this.
