From 8d56136d038a611ee69cfd6531a5b86028ef147b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=86var=20Arnfj=C3=B6r=C3=B0=20Bjarmason?= Date: Thu, 27 Jan 2022 06:26:43 +0100 Subject: [PATCH 1/7] object-name tests: add tests for ambiguous object blind spots MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Extend the tests for ambiguous objects to check how we handle objects where we return OBJ_BAD when trying to parse them. As noted in [1] we have a blindspot when it comes to this behavior. Since we need to add new test data here let's extend these tests to be tested under SHA-256, in d7a2fc82491 (t1512: skip test if not using SHA-1, 2018-05-13) all of the existing tests were skipped, as they rely on specific SHA-1 object IDs. For these tests it only matters that the first 4 characters of the OID prefix are the same for both SHA-1 and SHA-256. This uses strings that I mined, and have the same prefix when hashed with both. We "test_cmp" the full output to guard against any future regressions, and because a subsequent commit will tweak it. Showing a diff of how the output changes is helpful to explain those subsequent commits. The "sed" invocation in test_cmp_failed_rev_parse() doesn't need a "/g" because under both SHA-1 and SHA-256 we'll wildcard match any trailing part of the OID after our known starting prefix. We'd like to convert all of that to just "..." for the "test_cmp" which follows. 1. https://lore.kernel.org/git/YZwbphPpfGk78w2f@coredump.intra.peff.net/ Signed-off-by: Ævar Arnfjörð Bjarmason Signed-off-by: Junio C Hamano --- t/t1512-rev-parse-disambiguation.sh | 82 +++++++++++++++++++++++++++++ 1 file changed, 82 insertions(+) diff --git a/t/t1512-rev-parse-disambiguation.sh b/t/t1512-rev-parse-disambiguation.sh index 7891a6becf..010d9c1b8a 100755 --- a/t/t1512-rev-parse-disambiguation.sh +++ b/t/t1512-rev-parse-disambiguation.sh @@ -25,6 +25,88 @@ export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME . ./test-lib.sh +test_cmp_failed_rev_parse () { + dir=$1 + rev=$2 + + cat >expect && + test_must_fail git -C "$dir" rev-parse "$rev" 2>actual.raw && + sed "s/\($rev\)[0-9a-f]*/\1.../" actual && + test_cmp expect actual +} + +test_expect_success 'ambiguous blob output' ' + git init --bare blob.prefix && + ( + cd blob.prefix && + + # Both start with "dead..", under both SHA-1 and SHA-256 + echo brocdnra | git hash-object -w --stdin && + echo brigddsv | git hash-object -w --stdin && + + # Both start with "beef.." + echo 1agllotbh | git hash-object -w --stdin && + echo 1bbfctrkc | git hash-object -w --stdin + ) && + + test_must_fail git -C blob.prefix rev-parse dead && + test_cmp_failed_rev_parse blob.prefix beef <<-\EOF + error: short object ID beef... is ambiguous + hint: The candidates are: + hint: beef... blob + hint: beef... blob + fatal: ambiguous argument '\''beef...'\'': unknown revision or path not in the working tree. + Use '\''--'\'' to separate paths from revisions, like this: + '\''git [...] -- [...]'\'' + EOF +' + +test_expect_success 'ambiguous loose bad object parsed as OBJ_BAD' ' + git init --bare blob.bad && + ( + cd blob.bad && + + # Both have the prefix "bad0" + echo xyzfaowcoh | git hash-object -t bad -w --stdin --literally && + echo xyzhjpyvwl | git hash-object -t bad -w --stdin --literally + ) && + + test_cmp_failed_rev_parse blob.bad bad0 <<-\EOF + error: short object ID bad0... is ambiguous + hint: The candidates are: + fatal: invalid object type + EOF +' + +test_expect_success POSIXPERM 'ambigous zlib corrupt loose blob' ' + git init --bare blob.corrupt && + ( + cd blob.corrupt && + + # Both have the prefix "cafe" + echo bnkxmdwz | git hash-object -w --stdin && + oid=$(echo bmwsjxzi | git hash-object -w --stdin) && + + oidf=objects/$(test_oid_to_path "$oid") && + chmod 755 $oidf && + echo broken >$oidf + ) && + + test_cmp_failed_rev_parse blob.corrupt cafe <<-\EOF + error: short object ID cafe... is ambiguous + hint: The candidates are: + error: inflate: data stream error (incorrect header check) + error: unable to unpack cafe... header + error: inflate: data stream error (incorrect header check) + error: unable to unpack cafe... header + hint: cafe... unknown type + hint: cafe... blob + fatal: ambiguous argument '\''cafe...'\'': unknown revision or path not in the working tree. + Use '\''--'\'' to separate paths from revisions, like this: + '\''git [...] -- [...]'\'' + EOF +' + if ! test_have_prereq SHA1 then skip_all='not using SHA-1 for objects' From 6780e6804087a89bddfb0333171d005b309941a1 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=86var=20Arnfj=C3=B6r=C3=B0=20Bjarmason?= Date: Thu, 27 Jan 2022 06:26:44 +0100 Subject: [PATCH 2/7] object-name: explicitly handle OBJ_BAD in show_ambiguous_object() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Amend the "unknown type" handling in the code that displays the ambiguous object list to assert() that we're either going to get the "real" object types we can pass to type_name(), or a -1 (OBJ_BAD) return value from oid_object_info(). See [1] for the current output, and [1] for the commit that added the "unknown type" handling. We are never going to get an "unknown type" in the sense of custom types crafted with "hash-object --literally", since we're not using the OBJECT_INFO_ALLOW_UNKNOWN_TYPE flag. If we manage to otherwise unpack such an object without errors we'll die() in parse_loose_header_extended() called by sort_ambiguous() before we get to show_ambiguous_object(), as is asserted by the test added in the preceding commit. So saying "unknown type" here was always misleading, we really meant to say that we had a failure parsing the object at all, i.e. that we had repository corruption. If the problem is only that it's type is unknown we won't reach this code. So let's emit a generic "[bad object]" instead. As our tests added in the preceding commit show, we'll have emitted various "error" output already in those cases. We should do better in the truly "unknown type" cases, which we'd need to handle if we were passing down the OBJECT_INFO_ALLOW_UNKNOWN_TYPE flag. But let's leave that for some future improvement. In a subsequent commit I'll improve the output we do show, and not having to handle the "unknown type" (as in OBJECT_INFO_ALLOW_UNKNOWN_TYPE) simplifies that change. 1. 5cc044e0257 (get_short_oid: sort ambiguous objects by type, then SHA-1, 2018-05-10) 2. 1ffa26c461 (get_short_sha1: list ambiguous objects on error, 2016-09-26) Signed-off-by: Ævar Arnfjörð Bjarmason Signed-off-by: Junio C Hamano --- object-name.c | 14 ++++++++++++-- t/t1512-rev-parse-disambiguation.sh | 2 +- 2 files changed, 13 insertions(+), 3 deletions(-) diff --git a/object-name.c b/object-name.c index fdff4601b2..9750634ee7 100644 --- a/object-name.c +++ b/object-name.c @@ -361,6 +361,16 @@ static int show_ambiguous_object(const struct object_id *oid, void *data) return 0; type = oid_object_info(ds->repo, oid, NULL); + + if (type < 0) { + strbuf_addstr(&desc, "[bad object]"); + goto out; + } + + assert(type == OBJ_TREE || type == OBJ_COMMIT || + type == OBJ_BLOB || type == OBJ_TAG); + strbuf_addstr(&desc, type_name(type)); + if (type == OBJ_COMMIT) { struct commit *commit = lookup_commit(ds->repo, oid); if (commit) { @@ -374,9 +384,9 @@ static int show_ambiguous_object(const struct object_id *oid, void *data) strbuf_addf(&desc, " %s", tag->tag); } - advise(" %s %s%s", +out: + advise(" %s %s", repo_find_unique_abbrev(ds->repo, oid, DEFAULT_ABBREV), - type_name(type) ? type_name(type) : "unknown type", desc.buf); strbuf_release(&desc); diff --git a/t/t1512-rev-parse-disambiguation.sh b/t/t1512-rev-parse-disambiguation.sh index 010d9c1b8a..0282ada133 100755 --- a/t/t1512-rev-parse-disambiguation.sh +++ b/t/t1512-rev-parse-disambiguation.sh @@ -99,7 +99,7 @@ test_expect_success POSIXPERM 'ambigous zlib corrupt loose blob' ' error: unable to unpack cafe... header error: inflate: data stream error (incorrect header check) error: unable to unpack cafe... header - hint: cafe... unknown type + hint: cafe...
