First one is the only one exclusive to OpenBSD (tested with 6.7)
while the other 2 are likely also needed in other POSIX systems.

Seems to trigger a bug in at least OpenBSD's 6.7 sh where it is
interpreted as a history lookup and therefore fails 125-126, 128,
130.

Remove the subshell and get a space between ! and grep, so tests
pass successfully.

6c722cbe5a (bisect: allow CRLF line endings in "git bisect replay"
input, 2020-05-07) includes CR as a field separator, but doesn't
account for it being included in the last field, breaking when
running at least under OpenBSD 6.7's sh.

Read the revision into a raw variable and strip it of any possible
embeded CR characters, before use.

Instead of using a BRE, that broke tests 30-32, 37-39, 42 at least with
OpenBSD 6.7; use a simpler ERE.

That's quite unsatisfactory, as the whole point of adding CR to IFS
was to avoid having to spawn extra processes for this kind of text
processing.  If we were to do the preprocessing, we are better off
just passing the whole input thru "tr -d '\015'".

As we know that "rev" ought to consist of just hexadecimal and
cannot be split into two at $IFS even if we don't tell "read" that
"everything at the end of line is 'rev'", can we do

	while read git bisect command rev ignored

so that we'll get an empty string after CR in $ignored when reading
CRLF input, and an empty string because we ran out of the tokens
when reading LF input?

That is, ...

Thanks.  We already do use "test_i18ngrep -E" in another test, so
this should be safe.

It's strange that somebody thinks of doing history lookup in
non-interactive use.

But even more curious is why we have this in a subshell in the first
place.  I do not see a reason why we need subshell, nor use of the
double-quote in the outer layer that forces us to use backslashes.

This is obviously the minimum fix, so I'm willing to take the change
as-is, but if we were writing it today, perhaps

	! grep 'statistics:{"filter_not_present":' "$TRASH_DIRECTORY/trace.perf" &&

is how we write it.  I do not see any reason why we want to use the
"-q" option either.

that works (kind of), but will cause test t6030.66 to fail, with a git
segfault nonetheless, because we can't handle anymore a line line:

git bisect start '--term-new' 'term1' '--term-old' 'term2' '32a594a3fdac2d57cf6d02987e30eec68511498c' '88bcdc1839f0ad191ffdd65cae2a2a862d682151'

IMHO it will be probably still cleaner to do `tr -d '\015'`, even if the
patch below avoids all current issues from the testsuite.

will follow up with a fix for the segfault, unless someone else beats me to
it.

Subject: [PATCH v2] bisect: avoid tailing CR characters from revision in
 replay

6c722cbe5a (bisect: allow CRLF line endings in "git bisect replay"
input, 2020-05-07) includes CR as a field separator, but relies on
it not being included in the last field, which breaks at least when
running under OpenBSD 6.7's sh.

Instead of just assume the CR will get swallowed, read the rest of
the line into an otherwise unused variable and ignore it everywhere
except on the call for git bisect start, where it matters.

My initial attempt to handle CRLF logs was shaped like this:

	tr -d '\r' <"$file" | while read ...

This introduces a subshell, so there were concerns about propagating
variables and exits. So, Peff also suggested preprocessing to a file. Around
the same time Junio tried using IFS, and that was simpler.

It would be pretty easy to tr -d '\r' >"$GIT_DIR/BISECT_REPLAY_LOG" (or some
other name) and then read from that.

Two things I'm not sure of with such an approach:

1. Is $GIT_DIR the right place to put this? If not, is there a helper to
   create a temporary file? mktemp may not be available everywhere. I only
   see git-mergetool.sh using it and only behind the mergetool.writeToTemp
   variable.

2. How and when does this temp file need to be cleaned up? Looking at using
   something like trap "rm -f \"$temp_file\"" 0 will conflict with the traps
   that git-bisect.sh's bisect_start installs, and bisect_replay calls
   bisect_start. I could introduce a helper like
   maybe_unlink_temp_replay_log and invoke that from a trap installed in
   both bisect_replay and bisect_start.

   I looked at whether bisect.c's bisect_clean_state() is the right place to
   add such clean up: it does not look like the right place. It would result
   in the temp file getting deleted while it was being read. (git-bisect.sh
   -> bisect_replay()'s loop -> bisect_start() -> bisect--helper.c's
   bisect_start() -> bisect.c's bisect_clean_state()) Alas, not all file
   systems are OK with that happening.

Any guidance?

Here's a sketch that leaves cleanup on non-successful paths unaddressed.

bisect_replay () {
	file="$1"
	test "$#" -eq 1 || die "$(gettext "No logfile given")"
	test -r "$file" || die "$(eval_gettext "cannot read \$file for replaying")"
	git bisect--helper --bisect-reset || exit

	scrubbed_file="$GIT_DIR/BISECT_CLEANED_LOG"
	tr -d '\r' <"$file" >"scrubbed_file" || die "badness"

	while read git bisect command rev
	do ... done <"$scrubbed_file"

	rm -f "$scrubbed_file"
	bisect_auto_next

One thing was that extra processes and temporary files are pure
overhead when people don't use misbehaving editors, so we could just
say "don't do it then".  It may not be worth paying the cost of
being pessimistic and preparing for the worst.  The "$IFS will split
the tokens on the line for free for us" was a no-cost solution and
that was why I suggested it.

In any case, I think there are folks who are rewriting bisect piece
by piece to C, and at that point it would just be the matter of
using strbuf_getline_lf() vs strbuf_getline() to get rid of the
unwanted CR for free.
