Git Push卡住并出现Bad File Descriptor问题求助

Problem Details #

• Issue occurs only in a single Git repository
• git push gets stuck immediately after outputting:

  Writing objects: 100% (823/823), 73.56 MiB | 34.07 MiB/s, done.
  Total 823 (delta 522), reused 752 (delta 454), pack-reused 0
  

• Adjusting buffer with git config --global pack.windowMemory "32m" improved transfer speed but did not resolve the stuck issue
• strace -efile -f git push output shows:

  Writing objects: 100% (823/823), 73.56 MiB | 34.07 MiB/s, done.
  Total 823 (delta 522), reused 752 (delta 454), pack-reused 0
  [pid  2380] newfstatat(1, "", 0x7ffea1c08270, AT_EMPTY_PATH) = -1 EBADF (Bad file descriptor)
  [pid  2380] +++ exited with 0 +++
  [pid  2375] --- SIGCHLD {si_signo=SIGCHLD, si_code=CLD_EXITED, si_pid=2380, si_uid=1000, si_status=0, si_utime=70 /* 0.70 s */, si_stime=20 /* 0.20 s */}
  

Troubleshooting & Solutions #

1. Reset Remote Connection #

• Remove and re-add the remote origin to fix potential connection corruption:

  git remote remove origin
  git remote add origin <your-remote-repo-url>
  

• Pull latest changes to avoid conflicts before pushing:

  git pull origin <your-branch-name> --rebase
  

2. Repair Local Repository Corruption #

Single-repository issues often stem from local repo damage. Run these commands to fix:

• Clean up local cache aggressively:

  git gc --prune=now --aggressive
  

• Check for and repair repo integrity issues:

  git fsck --full
  

  If git fsck reports errors, re-cloning the repository is the most reliable fix (back up uncommitted changes first).

3. Disable Progress Output #

The EBADF error suggests a problem with stdout/stderr handling. Try pushing without progress output:

git push --no-progress

If this succeeds, configure the repo to disable progress by default:

git config --local transfer.hideProgress true
git config --local core.compression 0

4. Fix File Descriptor Issues #

EBADF indicates an invalid file descriptor. Try these steps:

• Open a new terminal window and re-run git push (current shell environment may be corrupted)
• Check current file descriptor limits:

  ulimit -n
  

• Temporarily raise the limit if it's too low:

  ulimit -n 10240
  

  Then attempt the push again.

5. Re-clone the Repository #

If all else fails:

1. Stash or back up uncommitted changes:

   git stash push -m "temp backup"
   

2. Delete the local repo and re-clone from remote:

   rm -rf <your-local-repo-dir>
   git clone <your-remote-repo-url>
   

3. Restore your changes and push:

   git stash pop
   git push
