The side-band demultiplexer that is used to display progress output
from the remote end did not clear the line properly when the end of
line hits at a packet boundary, which has been corrected. Also
comes with test clean-ups.
* jx/sideband-cleanup:
test: refactor to use "get_abbrev_oid" to get abbrev oid
test: refactor to use "test_commit" to create commits
test: compare raw output, not mangle tabs and spaces
sideband: don't lose clear-to-eol at packet boundary
|

Before comparing with the expect file, we used to call function
"make_user_friendly_and_stable_output" to filter out trailing spaces in
output. Ævar recommends using pattern "s/Z$//" to prepare expect file,
and then compare it with raw output.
Since we have fixed the issue of occasionally missing the clear-to-eol
suffix when displaying sideband #2 messages, it is safe and stable to
test against raw output.

Ævar reported that the function `make_user_friendly_and_stable_output()`
failed on a i386 box (gcc45) in the gcc farm boxes with error:
sed: couldn't re-allocate memory
It turns out that older versions of bash (4.3) or dash (0.5.7) cannot
evaluate expression like `${A%${A#???????}}` used to get the leading 7
characters of variable A.
Replace the incompatible parameter expansion so that t6020 works on
older version of bash or dash.

Removal of GIT_TEST_GETTEXT_POISON continues.
* ab/detox-gettext-tests:
tests: remove most uses of test_i18ncmp
tests: remove last uses of C_LOCALE_OUTPUT
tests: remove most uses of C_LOCALE_OUTPUT
tests: remove last uses of GIT_TEST_GETTEXT_POISON=false
|

As a follow-up to d162b25f956 (tests: remove support for
GIT_TEST_GETTEXT_POISON, 2021-01-20) remove most uses of test_i18ncmp
via a simple s/test_i18ncmp/test_cmp/g search-replacement.
I'm leaving t6300-for-each-ref.sh out due to a conflict with in-flight
changes between "master" and "seen", as well as the prerequisite
itself due to other changes between "master" and "next/seen" which add
new test_i18ncmp uses.

Rename the recently introduced test-bundle-functions.sh to be
consistent with other lib-*.sh files, which is the convention for
these sorts of shared test library functions.
The new test-bundle-functions.sh was introduced in 9901164d81d (test:
add helper functions for git-bundle, 2021-01-11). It was the only
test-*.sh of this nature.

In order to create an incremental bundle, we need to pass many arguments
to let git-bundle ignore some already packed commits. It will be more
convenient to pass args via stdin. But the current implementation does
not allow us to do this.
This is because args are parsed twice when creating bundle. The first
time for parsing args is in `compute_and_write_prerequisites()` by
running `git-rev-list` command to write prerequisites in bundle file,
and stdin is consumed in this step if "--stdin" option is provided for
`git-bundle`. Later nothing can be read from stdin when running
`setup_revisions()` in `create_bundle()`.
The solution is to parse args once by removing the entire function
`compute_and_write_prerequisites()` and then calling function
`setup_revisions()`. In order to write prerequisites for bundle, will
call `prepare_revision_walk()` and `traverse_commit_list()`. But after
calling `prepare_revision_walk()`, the object array `revs.pending` is
left empty, and the following steps could not work properly with the
empty object array (`revs.pending`). Therefore, make a copy of `revs`
to `revs_copy` for later use right after calling `setup_revisions()`.
The copy of `revs_copy` is not a deep copy, it shares the same objects
with `revs`. The object array of `revs` has been cleared, but objects
themselves are still kept. Flags of objects may change after calling
`prepare_revision_walk()`, we can use these changed flags without
calling the `git rev-list` command and parsing its output like the
former implementation.
Also add testcases for git bundle in t6020, which read args from stdin.

`git rev-list` will list one commit for the following command:
$ git rev-list 'main^!'
<tip-commit-of-main-branch>
But providing the same rev-list args to `git bundle`, fail to create
a bundle file.
$ git bundle create - 'main^!'
# v2 git bundle
-<OID> <one-line-message>
fatal: Refusing to create empty bundle.
This is because when removing duplicate objects in function
`object_array_remove_duplicates()`, one unique pending object which has
the same name is deleted by mistake. The revision arg 'main^!' in the
above example is parsed by `handle_revision_arg()`, and at lease two
different objects will be appended to `revs.pending`, one points to the
parent commit of the "main" branch, and the other points to the tip
commit of the "main" branch. These two objects have the same name
"main". Only one object is left with the name "main" after calling the
function `object_array_remove_duplicates()`.
And what's worse, when adding boundary commits into pending list, we use
one-line commit message as names, and the arbitory names may surprise
git-bundle.
Only comparing objects themselves (".item") is also not good enough,
because user may want to create a bundle with two identical objects but
with different reference names, such as: "HEAD" and "refs/heads/main".
Add new function `contains_object()` which compare both the address and
the name of the object.

Move git-bundle related functions from t5510 to a library, and this lib
will be shared with a new testcase t6020 which finds a known breakage of
"git-bundle".
