Worktree creation fails when path's are too long

[pingu2k4]

I have a repo with particularly long filenames, but they are in a folder close to the root of my drive and fit within the limit. When I try and create a worktree for this repo, it fails as it uses a longer base path.

This is on Windows.

Git command failed in GitCore.createWorktree: git worktree add -b t3code/1982b5aa C:\Users\ukdevaccount1\.t3\worktrees\studio\t3code-1982b5aa feature/1234-branch-name (C:\Users\ukdevaccount1\Dev\project) - Preparing worktree (new branch 't3code/1982b5aa') Updating files: 10% (240/2375) Updating files: 11% (262/2375) Updating files: 12% (285/2375) Updating files: 13% (309/2375) Updating files: 14% (333/2375) Updating files: 15% (357/2375) Updating files: 16% (380/2375) Updating files: 17% (404/2375) Updating files: 18% (428/2375) Updating files: 19% (452/2375) Updating files: 19% (463/2375) Updating files: 20% (475/2375) Updating files: 21% (499/2375) Updating files: 22% (523/2375) Updating files: 23% (547/2375) Updating files: 24% (570/2375) Updating files: 25% (594/2375) Updating files: 26% (618/2375) Updating files: 27% (642/2375) Updating files: 28% (665/2375) Updating files: 29% (689/2375) Updating files: 30% (713/2375) Updating files: 31% (737/2375) Updating files: 31% (740/2375) Updating files: 32% (760/2375) Updating files: 33% (784/2375) Updating files: 34% (808/2375) Updating files: 35% (832/2375) Updating files: 36% (855/2375) Updating files: 37% (879/2375) Updating files: 38% (903/2375) Updating files: 39% (927/2375) Updating files: 40% (950/2375) Updating files: 41% (974/2375) Updating files: 42% (998/2375) Updating files: 42% (1015/2375) Updating files: 43% (1022/2375) Updating files: 44% (1045/2375) Updating files: 45% (1069/2375) Updating files: 46% (1093/2375) Updating files: 47% (1117/2375) Updating files: 48% (1140/2375) Updating files: 49% (1164/2375) Updating files: 50% (1188/2375) Updating files: 51% (1212/2375) Updating files: 52% (1235/2375) Updating files: 53% (1259/2375) error: unable to create file src/ProcessOps1/AppA1/src/ProcessOps1.AppA1.Web.Portal/Views/CompanySpace/CompanySpaceView/Tabs/SupplierProfiles/UpdateSupplierProfileStatusX/Services/UpdateSupplierProfileStatusXServiceLoggerExtensions.cs: Filename too long Updating files: 53% (1282/2375) Updating files: 54% (1283/2375) Updating files: 55% (1307/2375) Updating files: 56% (1330/2375) Updating files: 57% (1354/2375) Updating files: 58% (1378/2375) Updating files: 59% (1402/2375) Updating files: 60% (1425/2375) Updating files: 61% (1449/2375) Updating files: 62% (1473/2375) Updating files: 63% (1497/2375) Updating files: 63% (1515/2375) Updating files: 64% (1520/2375) Updating files: 65% (1544/2375) Updating files: 66% (1568/2375) Updating files: 67% (1592/2375) Updating files: 68% (1615/2375) Updating files: 69% (1639/2375) Updating files: 70% (1663/2375) Updating files: 71% (1687/2375) Updating files: 72% (1710/2375) Updating files: 73% (1734/2375) Updating files: 74% (1758/2375) Updating files: 75% (1782/2375) Updating files: 75% (1788/2375) Updating files: 76% (1805/2375) Updating files: 77% (1829/2375) Updating files: 78% (1853/2375) Updating files: 79% (1877/2375) Updating files: 80% (1900/2375) Updating files: 81% (1924/2375) Updating files: 82% (1948/2375) Updating files: 83% (1972/2375) Updating files: 84% (1995/2375) Updating files: 85% (2019/2375) Updating files: 86% (2043/2375) Updating files: 86% (2055/2375) Updating files: 87% (2067/2375) Updating files: 88% (2090/2375) Updating files: 89% (2114/2375) Updating files: 90% (2138/2375) Updating files: 91% (2162/2375) Updating files: 92% (2185/2375) Updating files: 93% (2209/2375) Updating files: 94% (2233/2375) Updating files: 95% (2257/2375) Updating files: 96% (2280/2375) Updating files: 96% (2291/2375) Updating files: 97% (2304/2375) Updating files: 98% (2328/2375) Updating files: 99% (2352/2375) Updating files: 100% (2375/2375) Updating files: 100% (2375/2375), done. fatal: Could not reset index file to revision 'HEAD'.

Error while creating worktree

Context

• Operation: GitCore.createWorktree
• Repository: C:\Users\ukdevaccount1\Dev\project
• Command:
  git worktree add -b t3code/1982b5aa C:\Users\ukdevaccount1\.t3\worktrees\studio\t3code-1982b5aa feature/1234-branch-name

Observed result

• The worktree creation started successfully.

• File checkout progressed until 53%.

• Git then failed with a Windows path-length error on the following file:

  src/ProcessOps1/AppA1/src/ProcessOps1.AppA1.Web.Portal/Views/CompanySpace/CompanySpaceView/Tabs/SupplierProfiles/UpdateSupplierProfileStatusX/Services/UpdateSupplierProfileStatusXServiceLoggerExtensions.cs

Error output

• error: unable to create file : Filename too long
• fatal: Could not reset index file to revision 'HEAD'

Relevant log excerpt

• Preparing worktree (new branch 't3code/1982b5aa')
• Updating files...
• error: unable to create file src/ProcessOps1/AppA1/src/ProcessOps1.AppA1.Web.Portal/Views/CompanySpace/CompanySpaceView/Tabs/SupplierProfiles/UpdateSupplierProfileStatusX/Services/UpdateSupplierProfileStatusXServiceLoggerExtensions.cs: Filename too long
• fatal: Could not reset index file to revision 'HEAD'

Likely cause

• The target worktree path on Windows is too long once combined with a very deeply nested repository file path.

Worktree path

• C:\Users\ukdevaccount1\.t3\worktrees\studio\t3code-1982b5aa

Base branch

• feature/1234-branch-name

New branch

• t3code/1982b5aa
