This test delivers all possible (single-root) four-message threads in all possible orders and checks that notmuch successfully links them into threads in every case.
This is introduced as a new test (rather than just adding it to T050-new) because it's much easier for this to start with an empty database. --- I thought I saw a bug in the thread linking code. It turned out to be okay, but I wrote this test to convince myself. As far as I can tell, we don't have any tests specifically for thread linking. We certainly don't have any that are this systematic. test/T051-new-linking.sh | 43 +++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 43 insertions(+) create mode 100755 test/T051-new-linking.sh diff --git a/test/T051-new-linking.sh b/test/T051-new-linking.sh new file mode 100755 index 0000000..b6d778a --- /dev/null +++ b/test/T051-new-linking.sh @@ -0,0 +1,43 @@ +#!/usr/bin/env bash +test_description='"notmuch new" thread linking' + +. ./test-lib.sh + +test_begin_subtest "All four-message threads get linked in all delivery orders" +# Generate all possible single-root four message thread structures. +# Each line in THREADS is a thread structure, where the n'th field is +# the parent of message n. +THREADS=$(python -c ' +def mkTrees(free, tree={}): + if not free: + print(" ".join(map(str, [msg[1] for msg in sorted(tree.items())]))) + return + # Attach each free message to each message in the tree (if there is + # no tree, make the free message the root) + for msg in sorted(free): + parents = sorted(tree.keys()) if tree else ["none"] + for parent in parents: + ntree = tree.copy() + ntree[msg] = parent + mkTrees(free - set([msg]), ntree) +mkTrees(set(range(4)))') +for ((n = 0; n < 4; n++)); do + # Deliver the n'th message of every thread + thread=0 + while read -a parents; do + parent=${parents[$n]} + generate_message \ + [id]=m$n at t$thread [in-reply-to]="\<m$parent at t$thread\>" \ + [subject]=p$thread [from]=m$n + thread=$((thread + 1)) + done <<< "$THREADS" + notmuch new > /dev/null +done +output=$(notmuch search '*' | notmuch_search_sanitize) +nthreads=$(wc -l <<< "$THREADS") +expected=$(for ((i = 0; i < $nthreads; i++)); do + echo "thread:XXX 2001-01-05 [4/4] m3, m2, m1, m0; p$i (inbox unread)" + done) +test_expect_equal "$output" "$expected" + +test_done -- 1.8.4.rc3
