"rebase -i" ceased to run post-commit hook by mistake in an earlier update, which has been corrected. * pw/post-commit-from-sequencer: sequencer: run post-commit hook move run_commit_hook() to libgit and use it there sequencer.h fix placement of #endif t3404: remove uneeded calls to set_fake_editor t3404: set $EDITOR in subshell t3404: remove unnecessary subshell

# Helper functions used by interactive rebase tests.
|
|
|
|
# After setting the fake editor with this function, you can
|
|
#
|
|
# - override the commit message with $FAKE_COMMIT_MESSAGE
|
|
# - amend the commit message with $FAKE_COMMIT_AMEND
|
|
# - check that non-commit messages have a certain line count with $EXPECT_COUNT
|
|
# - check the commit count in the commit message header with $EXPECT_HEADER_COUNT
|
|
# - rewrite a rebase -i script as directed by $FAKE_LINES.
|
|
# $FAKE_LINES consists of a sequence of words separated by spaces.
|
|
# The following word combinations are possible:
|
|
#
|
|
# "<lineno>" -- add a "pick" line with the SHA1 taken from the
|
|
# specified line.
|
|
#
|
|
# "<cmd> <lineno>" -- add a line with the specified command
|
|
# ("pick", "squash", "fixup", "edit", "reword" or "drop") and the
|
|
# SHA1 taken from the specified line.
|
|
#
|
|
# "exec_cmd_with_args" -- add an "exec cmd with args" line.
|
|
#
|
|
# "#" -- Add a comment line.
|
|
#
|
|
# ">" -- Add a blank line.
