From 88124ab263670b4252be7c13d03754a127cee90e Mon Sep 17 00:00:00 2001 From: Jeff King Date: Fri, 27 Mar 2020 04:03:00 -0400 Subject: test-lib-functions: make packetize() more efficient The packetize() function takes its input on stdin, and requires 4 separate sub-processes to format a simple string. We can do much better by getting the length via the shell's "${#packet}" construct. The one caveat is that the shell can't put a NUL into a variable, so we'll have to continue to provide the stdin form for a few calls. There are a few other cleanups here in the touched code: - the stdin form of packetize() had an extra stray "%s" when printing the packet - the converted calls in t5562 can be made simpler by redirecting output as a block, rather than repeated appending Signed-off-by: Jeff King Signed-off-by: Junio C Hamano --- t/t5562-http-backend-content-length.sh | 19 ++++++++++++------- 1 file changed, 12 insertions(+), 7 deletions(-) (limited to 't/t5562-http-backend-content-length.sh') diff --git a/t/t5562-http-backend-content-length.sh b/t/t5562-http-backend-content-length.sh index 4a110b307e..3f4ac71f83 100755 --- a/t/t5562-http-backend-content-length.sh +++ b/t/t5562-http-backend-content-length.sh @@ -53,15 +53,20 @@ test_expect_success 'setup' ' test_commit c1 && hash_head=$(git rev-parse HEAD) && hash_prev=$(git rev-parse HEAD~1) && - printf "want %s" "$hash_head" | packetize >fetch_body && - printf 0000 >>fetch_body && - printf "have %s" "$hash_prev" | packetize >>fetch_body && - printf done | packetize >>fetch_body && + { + packetize "want $hash_head" && + printf 0000 && + packetize "have $hash_prev" && + packetize "done" + } >fetch_body && test_copy_bytes 10 fetch_body.trunc && hash_next=$(git commit-tree -p HEAD -m next HEAD^{tree}) && - printf "%s %s refs/heads/newbranch\\0report-status\\n" "$ZERO_OID" "$hash_next" | packetize >push_body && - printf 0000 >>push_body && - echo "$hash_next" | git pack-objects --stdout >>push_body && + { + printf "%s %s refs/heads/newbranch\\0report-status\\n" \ + "$ZERO_OID" "$hash_next" | packetize && + printf 0000 && + echo "$hash_next" | git pack-objects --stdout + } >push_body && test_copy_bytes 10 push_body.trunc && : >empty_body ' -- cgit v1.2.3
