Re: [PATCH] t5540-http-test: shorten grep pattern

Hmm...

Is it sensible to replace $x40 with X40 and $x38 with X38 on any line
anywhere for the purpose of this test? As the downstream test is only
interested in a line with HTTP request line that asks for a specific path
under objects/??/?{38}_?{40}, wouldn't it make more sense to replace
occurrences of only such line?

	sed -n \
            -e "s/PUT /OP " \
	    -e "s/MOVE /OP /" \
	    -e "s|/objects/$x2/$x38_$x40|WANTED_PATH_REQUEST|p" \
	    "$HTTPD_ROOT_PATH/access.log" |
	grep -e "\"OP .*WANTED_PATH_REQUEST HTTP/[.0-9]*\" 20[0-9] "

On OS X, the grep pattern

    "\"OP .*/objects/$x2/X38_X40 HTTP/[.0-9]*\" 20[0-9] "

is too long ($x38 and $x40 represent 38 and 40 copies of [0-9a-f]) for
grep to handle.  In order to still be able to match this, use the sed
invocation to replace what we're looking for with a token.

Yes, of course.  The reason it ended up the way it did was that I first
tried replacing $x40 with SHA-1, but that was still too long.  Your way
makes more sense in the end, although the $x38_$x40 bit needs to be
${x38}_$x40 so the shell looks for the right variable.
