Fails on MacOS: "readlink: illegal option -- f"

[lzkelley]

daedalus:illpy lzkelley$ ../fast-export/hg-fast-export.sh -r ../_illpy/
readlink: illegal option -- f
usage: readlink [-n] [file ...]

Error: The option core.ignoreCase is set to true in the git
repository. This will produce empty changesets for renames that just
change the case of the file name.
Use --force to skip this check or change the option with
git config core.ignoreCase false

It looks like this parameter only works on linux. They fixed the issue here just checking what the OS is.

Temporary (local) Fix: removing the -f flag in hg-fast-export.sh works fine.

Also: I did have issues with the path resolution also. If I run the script as ../fast-export/hg-fast-export.sh -r ../_illpy/ it couldn't find hg-fast-export.py... so I ended up just copying all of the scripts to my current directory (my new git repository) and running the script from there.

Unfortunately the fix you referred to just avoids the crash, it does not canonicalize the path.

Please try the fix in this branch and report back. It should behave as before the symlink support was added if you call fast-export by the full path and give a proper error message if it is called via a symlink and readlink is missing or does not understand `-f.

If you want fast-export callable using a symlink you need to install coreutils using Homebrew or MacPorts.

@frej I just tried the readlink-fix-branch and it worked for me, when using the full path!

Thanks!
