This is part 2 in the series to make tests hash independent. This series introduces an SHA1 prerequisite which checks if the hash in use is SHA-1, and can be used to skip the test if it is not. Additionally, because NewHash will be 256-bit, I introduced aliases for the test constants $_x40 and $_z40 which will be less confusing when the hash isn't 40 hex characters long. I opted to leave the old names in place for the moment to prevent any potential conflicts with other series and will clean up any stragglers later.
Several tests are skipped because of SHA-1-specific dependencies: some of these are core tests which test basic expected hash values, some depend on colliding short names, and some depend on specially named object (the pack tests). Elsewhere, tests are modified to compute values using git hash-object and git rev-parse. There is one cleanup patch that fixes indentation so we can use an indented heredoc in the following patch. The order in this series is by patch type, then roughly by test number. All of these tests pass with an alternate 160-bit hash as well as SHA-1. An additional series cleaning up the remainder of the tests is required to make the entire testsuite pass with an alternate 160-bit hash. brian m. carlson (28): t/test-lib: add an SHA1 prerequisite t/test-lib: introduce ZERO_OID t: switch $_z40 to $ZERO_OID t/test-lib: introduce FULL_HEX t: switch $_x40 to $FULL_HEX t0000: annotate with SHA1 prerequisite t1007: annotate with SHA1 prerequisite t1512: skip test if not using SHA-1 t4044: skip test if not using SHA-1 t: skip pack tests if not using SHA-1 t2203: abstract away SHA-1-specific constants t3103: abstract away SHA-1-specific constants t3702: abstract away SHA-1-specific constants t3905: abstract away SHA-1-specific constants t4007: abstract away SHA-1-specific constants t4008: abstract away SHA-1-specific constants t4014: abstract away SHA-1-specific constants t4020: abstract away SHA-1-specific constants t4022: abstract away SHA-1-specific constants t4029: fix test indentation t4029: abstract away SHA-1-specific constants t4030: abstract away SHA-1-specific constants t/lib-diff-alternative: abstract away SHA-1-specific constants t4205: sort log output in a hash-independent way t4042: abstract away SHA-1-specific constants t4045: abstract away SHA-1-specific constants t4208: abstract away SHA-1-specific constants t5300: abstract away SHA-1-specific constants t/diff-lib.sh | 4 +- t/lib-diff-alternative.sh | 12 ++++-- t/t0000-basic.sh | 24 ++++++------ t/t0090-cache-tree.sh | 2 +- t/t1000-read-tree-m-3way.sh | 2 +- t/t1001-read-tree-m-2way.sh | 2 +- t/t1002-read-tree-m-u-2way.sh | 2 +- t/t1006-cat-file.sh | 8 ++-- t/t1007-hash-object.sh | 16 ++++---- t/t1012-read-tree-df.sh | 2 +- t/t1400-update-ref.sh | 2 +- t/t1407-worktree-ref-store.sh | 8 ++-- t/t1450-fsck.sh | 4 +- t/t1501-work-tree.sh | 6 +-- t/t1512-rev-parse-disambiguation.sh | 6 +++ t/t1601-index-bogus.sh | 2 +- t/t1700-split-index.sh | 2 +- t/t2011-checkout-invalid-head.sh | 2 +- t/t2025-worktree-add.sh | 8 ++-- t/t2027-worktree-list.sh | 2 +- t/t2107-update-index-basic.sh | 4 +- t/t2201-add-update-typechange.sh | 16 ++++---- t/t2203-add-intent.sh | 14 +++---- t/t3100-ls-tree-restrict.sh | 2 +- t/t3101-ls-tree-dirname.sh | 2 +- t/t3103-ls-tree-misc.sh | 3 +- t/t3200-branch.sh | 4 +- t/t3510-cherry-pick-sequence.sh | 8 ++-- t/t3702-add-edit.sh | 7 ++-- t/t3905-stash-include-untracked.sh | 12 +++--- t/t4002-diff-basic.sh | 2 +- t/t4006-diff-mode.sh | 2 +- t/t4007-rename-3.sh | 17 +++++---- t/t4008-diff-break-rewrite.sh | 59 ++++++++++++++++------------- t/t4014-format-patch.sh | 11 +++--- t/t4020-diff-external.sh | 18 +++++---- t/t4022-diff-rewrite.sh | 5 ++- t/t4027-diff-submodule.sh | 6 +-- t/t4029-diff-trailing-space.sh | 38 ++++++++++--------- t/t4030-diff-textconv.sh | 5 ++- t/t4042-diff-textconv-caching.sh | 16 +++++--- t/t4044-diff-index-unique-abbrev.sh | 6 +++ t/t4045-diff-relative.sh | 6 ++- t/t4046-diff-unmerged.sh | 14 +++---- t/t4054-diff-bogus-tree.sh | 12 +++--- t/t4058-diff-duplicates.sh | 12 +++--- t/t4150-am.sh | 4 +- t/t4200-rerere.sh | 2 +- t/t4201-shortlog.sh | 2 +- t/t4205-log-pretty-formats.sh | 8 ++-- t/t4208-log-magic-pathspec.sh | 3 +- t/t5150-request-pull.sh | 2 +- t/t5300-pack-object.sh | 8 ++-- t/t5308-pack-detect-duplicates.sh | 6 +++ t/t5309-pack-delta-cycles.sh | 6 +++ t/t5516-fetch-push.sh | 22 +++++------ t/t5527-fetch-odd-refs.sh | 2 +- t/t5571-pre-push-hook.sh | 8 ++-- t/t6006-rev-list-format.sh | 4 +- t/t6012-rev-list-simplify.sh | 2 +- t/t6111-rev-list-treesame.sh | 2 +- t/t6120-describe.sh | 2 +- t/t6300-for-each-ref.sh | 2 +- t/t6301-for-each-ref-errors.sh | 2 +- t/t7009-filter-branch-null-sha1.sh | 2 +- t/t7011-skip-worktree-reading.sh | 2 +- t/t7064-wtstatus-pv2.sh | 58 ++++++++++++++-------------- t/t7506-status-submodule.sh | 2 +- t/t9010-svn-fe.sh | 14 +++---- t/t9300-fast-import.sh | 6 +-- t/test-lib.sh | 11 +++++- 71 files changed, 331 insertions(+), 268 deletions(-)
