The verbose output of the test 'reword without issues functions as
intended' in 't3423-rebase-reword.sh', added in a9279c6785 (sequencer:
do not squash 'reword' commits when we hit conflicts, 2018-06-19),
contains the following error output:
sed: -e expression #1, char 2: extra characters after command
This error comes from within the 'fake-editor.sh' script created by
'lib-rebase.sh's set_fake_editor() function, and the root cause is the
FAKE_LINES="pick 1 reword 2" variable in the test in question, in
particular the "pick" word. 'fake-editor.sh' assumes 'pick' to be the
default rebase command and doesn't support an explicit 'pick' command
in FAKE_LINES. As a result, 'pick' will be used instead of a line
number when assembling the following 'sed' script:
sed -n picks/^pick/pick/p
which triggers the aforementioned error.
Luckily, this didn't affect the test's correctness: the erroring 'sed'
command doesn't write anything to the todo script, and processing the
rest of FAKE_LINES generates the desired todo script, as if that
'pick' command were not there at all.
The minimal fix would be to remove the 'pick' word from FAKE_LINES,
but that would leave us susceptible to similar issues in the future.
Instead, teach the fake-editor script to recognize an explicit 'pick'
command, which is still a fairly trivial change.
In the future we might want to consider reinforcing this fake editor
script with an &&-chain and stricter parsing of the FAKE_LINES
variable (e.g. to error out when encountering unknown rebase commands
or commands and line numbers in the wrong order).

# 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.
