Jonathan NiederMake sure that the sample hooks do not use any shell features that the shell used to execute them does not support.
The documentation at the end of the sample pre-rebase script will never be executed, but "sh -n" does not know that. Convert it to a HERE document to avoid spurious failures.
If the shell specified in a hook’s #! line has a space in it, the new test will break it into words, not even taking quoting into account. So
#!"c:/Program Files/bin/bash.exe"
specifies a shell named ‘"c:/Program’ with argument ‘Files/bin/bash.exe"’. On Unix, that is exactly what exec() would do; on Windows, it is close to what the exec() compatibility layer does (actually, the ‘Files/bin/bash.exe"’ argument is thrown away by parse_interpreter()). To honor quoting during tests would be to set unreasonable expectations for runtime.
The user may want to avoid specifying a path to the shell at all, by building with
make 'SHELL_PATH=/usr/bin/env bash'
The rules used in tests and at runtime on Unix allow this.
Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> --- As before[1], the real motivation is the change to appease sh -n for pre-rebase, since I occasionally run a test like this locally. Patch is against master.
Thoughts?
