# |
|
# fatal: 'origin': unable to chdir or not a git archive |
|
# fatal: The remote end hung up unexpectedly |
|
# |
|
# because git would find the .git/config for the "trash directory" |
|
# repo, not for the clone-repo repo. The "trash directory" repo |
|
# had no entry for origin. Git found the wrong .git because |
|
# git rev-parse --show-cdup printed a path relative to |
|
# clone-repo/subdir/, not subdir-link/. Git rev-parse --show-cdup |
|
# used the correct .git, but when the git pull shell script did |
|
# "cd `git rev-parse --show-cdup`", it ended up in the wrong |
|
# directory. A POSIX shell's "cd" works a little differently |
|
# than chdir() in C; "cd -P" is much closer to chdir(). |
