Subject: rev-parse: exit with non-zero status if ref@{n} is not valid.
X-Git-Tag: v1.7.3-rc0~4^2~3
X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/e6eedc31d5c3d448d000eecb678ce891a4800b54?hp=e6eedc31d5c3d448d000eecb678ce891a4800b54

rev-parse: exit with non-zero status if ref@{n} is not valid.

"The current behaviour of ref@{...} syntax parser is suboptimal:

$ git rev-parse --verify jch@{99999} && echo true
warning: Log for 'jch' only has 1368 entries.
cfb88e9a8d4926b0011ae2dd67e1f57a98f4b768
true

It even knows that it is running off the cut-off point; it should just
cause the caller to notice that fact.  I don't think changing it to error
out should cause any harm to existing callers."

With this change:

$ git rev-parse --verify jch@{99999} || echo false
fatal: Log for 'jch' only has 1368 entries.
false

$ git rev-parse jch@{99999} || echo false
fatal: Log for 'jch' only has 1368 entries.
false
