Unlike other test helper functions, 'test_oid' doesn't terminate its
output with a LF, but, alas, the reason for this, if any, is not
mentioned in 2c02b110da
(t: add test functions to translate
hash-related values, 2018-09-13)).
Now, in the vast majority of cases 'test_oid' is invoked in a command
substitution that is part of a heredoc or supplies an argument to a
command or the value to a variable, and the command substitution would
chop off any trailing LFs, so in these cases the lack or presence of a
trailing LF in its output doesn't matter. However:
- There appear to be only three cases where 'test_oid' is not
invoked in a command substitution:
$ git grep '\stest_oid ' -- ':/t/*.sh'
t0000-basic.sh: test_oid zero >actual &&
t0000-basic.sh: test_oid zero >actual &&
t0000-basic.sh: test_oid zero >actual &&
These are all in test cases checking that 'test_oid' actually
works, and that the size of its output matches the size of the
corresponding hash function with conditions like
test $(wc -c <actual) -eq 40
In these cases the lack of trailing LF does actually matter,
though they could be trivially updated to account for the presence
of a trailing LF.
- There are also a few cases where the lack of trailing LF in
'test_oid's output actually hurts, because tests need to compare
its output with LF terminated file contents, forcing developers to
invoke it as 'echo $(test_oid ...)' to append the missing LF:
$ git grep 'echo "\?$(test_oid ' -- ':/t/*.sh'
t1302-repo-version.sh: echo $(test_oid version) >expect &&
t1500-rev-parse.sh: echo "$(test_oid algo)" >expect &&
t4044-diff-index-unique-abbrev.sh: echo "$(test_oid val1)" > foo &&
t4044-diff-index-unique-abbrev.sh: echo "$(test_oid val2)" > foo &&
t5313-pack-bounds-checks.sh: echo $(test_oid oidfff) >file &&
And there is yet another similar case in an in-flight topic at:
https://public-inbox.org/git/813e81a058227bd373cec802e443fcd677042fb4.1670862677.git.gitgitgadget@gmail.com/
Arguably we would be better off if 'test_oid' terminated its output
with a LF. So let's update 'test_oid' accordingly, update its tests
in t0000 to account for the extra character in those size tests, and
remove the now unnecessary 'echo $(...)' command substitutions around
'test_oid' invocations as well.
