Fixed a bug that caused spurious DEL characters (\177) to appear in double-quoted expansion where the RHS is evaluated to the empty string. so, in particular, I've removed all of the '' from the tests. I also downloaded bash 4.2 and tested everything with that. Seems to be working well! Thanks for catching this! --- This patchset now depends "[PATCH 1/8] tests (rebase): spell out the `--keep-empty` option" which is the first patch of Johannes's "Do not use abbreviated options in tests" patchset[1]. (Thanks for catching that, Johannes!) Changes since v1: * Squashed old set into one patch * Fixed indentation style and dangling else * Added more documentation after discussion with Ævar Changes since v2: * Add testing for rebase --fork-point behaviour * Add testing for rebase fast-forward behaviour * Make rebase --onto fast-forward in more cases * Update documentation to include use-case Changes since v3: * Fix tests failing on bash 4.2 * Fix typo in t3431 comment [1]: https://public-inbox.org/git/a1b4b74b9167e279dae4cd8c58fb28d8a714a66a.1553537656.git.gitgitgadget@gmail.com/ Denton Liu (4): t3431: add rebase --fork-point tests t3432: test rebase fast-forward behavior rebase: fast-forward --onto in more cases rebase: teach rebase --keep-base Documentation/git-rebase.txt | 30 +++++++++++-- builtin/rebase.c | 72 +++++++++++++++++++++++--------- t/t3400-rebase.sh | 2 +- t/t3404-rebase-interactive.sh | 2 +- t/t3416-rebase-onto-threedots.sh | 57 +++++++++++++++++++++++++ t/t3431-rebase-fork-point.sh | 57 +++++++++++++++++++++++++ t/t3432-rebase-fast-forward.sh | 62 +++++++++++++++++++++++++++ 7 files changed, 258 insertions(+), 24 deletions(-) create mode 100755 t/t3431-rebase-fork-point.sh create mode 100755 t/t3432-rebase-fast-forward.sh Interdiff against v3: diff --git a/t/t3431-rebase-fork-point.sh b/t/t3431-rebase-fork-point.sh index 0311bcbc68..e63040932f 100755 --- a/t/t3431-rebase-fork-point.sh +++ b/t/t3431-rebase-fork-point.sh @@ -11,7 +11,7 @@ test_description='git rebase --fork-point test' # \ # C*---F---G (side) # -# C was formerly part of master but is side out +# C was formerly part of master but master was rewound to remove C # test_expect_success setup ' test_commit A && @@ -29,29 +29,29 @@ test_expect_success setup ' test_rebase() { expected="$1" && shift && - test_expect_success "git rebase $@" " + test_expect_success "git rebase $*" " git checkout master && git reset --hard E && git checkout side && git reset --hard G && - git rebase $@ && + git rebase $* && test_write_lines $expected >expect && git log --pretty=%s >actual && test_cmp expect actual " } -test_rebase 'G F E D B A' '' -test_rebase 'G F D B A' '--onto D' -test_rebase 'G F B A' '--keep-base' -test_rebase 'G F C E D B A' '--no-fork-point' -test_rebase 'G F C D B A' '--no-fork-point --onto D' -test_rebase 'G F C B A' '--no-fork-point --keep-base' -test_rebase 'G F E D B A' '--fork-point refs/heads/master' -test_rebase 'G F D B A' '--fork-point --onto D refs/heads/master' -test_rebase 'G F B A' '--fork-point --keep-base refs/heads/master' -test_rebase 'G F C E D B A' 'refs/heads/master' -test_rebase 'G F C D B A' '--onto D refs/heads/master' -test_rebase 'G F C B A' '--keep-base refs/heads/master' +test_rebase 'G F E D B A' +test_rebase 'G F D B A' --onto D +test_rebase 'G F B A' --keep-base +test_rebase 'G F C E D B A' --no-fork-point +test_rebase 'G F C D B A' --no-fork-point --onto D +test_rebase 'G F C B A' --no-fork-point --keep-base +test_rebase 'G F E D B A' --fork-point refs/heads/master +test_rebase 'G F D B A' --fork-point --onto D refs/heads/master +test_rebase 'G F B A' --fork-point --keep-base refs/heads/master +test_rebase 'G F C E D B A' refs/heads/master +test_rebase 'G F C D B A' --onto D refs/heads/master +test_rebase 'G F C B A' --keep-base refs/heads/master test_done diff --git a/t/t3432-rebase-fast-forward.sh b/t/t3432-rebase-fast-forward.sh index 8585c21c5c..f493ce64c4 100755 --- a/t/t3432-rebase-fast-forward.sh +++ b/t/t3432-rebase-fast-forward.sh @@ -18,34 +18,34 @@ test_expect_success setup ' test_rebase_same_head() { status="$1" && shift && - test_expect_$status "git rebase $@ with $changes is no-op" " + test_expect_$status "git rebase $* with $changes is no-op" " oldhead=\$(git rev-parse HEAD) && test_when_finished 'git reset --hard \$oldhead' && - git rebase $@ && + git rebase $* && newhead=\$(git rev-parse HEAD) && test_cmp_rev \$oldhead \$newhead " } changes='no changes' -test_rebase_same_head success '' -test_rebase_same_head success 'master' -test_rebase_same_head success '--onto B B' -test_rebase_same_head success '--onto B...
