Subject: t/lib-pager: use sane_unset() to avoid breaking &&-chain

This test intentionally breaks the &&-chain following `unset` since it
doesn't know if `unset` will succeed or fail and doesn't want a local
`unset` failure to abort the test overall. We can do better by using
sane_unset() which can be linked into the &&-chain as usual.

Subject: t1010: fix unnoticed failure on Windows

On Microsoft Windows, a directory name should never end with a period.
Quoting from Microsoft documentation[1]:

    Do not end a file or directory name with a space or a period.
    Although the underlying file system may support such names, the
    Windows shell and user interface does not.

Naming a directory with a trailing period is indeed perilous:

    % git init foo
    % cd foo
    % mkdir a.
    % git status
    warning: could not open directory 'a./': No such file or directory

The t1010 "setup" test:

    for d in a a. a0
    do
        mkdir "$d" && echo "$d/one" >"$d/one" &&
        git add "$d"
    done &&

runs afoul of this Windows limitation, as can be observed when running
the test verbosely:

    error: open("a./one"): No such file or directory
    error: unable to index file 'a./one'
    fatal: adding files failed

The reason this problem has gone unnoticed for so long is twofold.
First, the failed `git add` is swallowed silently because the loop is
not terminated explicitly by `|| return 1` to signal the failure.
Second, none of the tests in this script care about the literal
directory names ("a", "a.", "a0") or the specific number of tree
entries. They care instead about the order of entries in the tree, and
that the tree synthesized in the index and created by `git write-tree`
matches the tree created by the output of `git ls-tree` fed into `git
mktree`, thus the absence of "a./one" has no impact on the tests.

Skipping these tests on Windows by, for instance, checking the
FUNNYNAMES predicate would avoid the problem, however, the funny-looking
name is not what is being tested here. Rather, the tests are about
checking that `git mktree` produces stable results for various input
conditions, such as when the input order is not consistent or when an
object is missing.

Therefore, resolve the problem simply by using a directory name which is
legal on Windows and sorts the same as "a.". While at it, add the
missing `|| return 1` to the loop body in order to catch this sort of
problem in the future.

Subject: t1020: avoid aborting entire test script when one test fails

Although `exit 1` is the proper way to signal a test failure from within
a subshell, its use outside any subshell should be avoided since it
aborts the entire script rather than aborting only the failed test.
Instead, a simple `return 1` is the proper idiom for signaling failure
outside a subshell since it aborts only the test in question, not the
entire script.

Subject: t4202: clarify intent by creating expected content less cleverly

Several tests assign the output of `$(...)` command substitution to an
"expect" variable, taking advantage of the fact that `$(...)` folds out
the final line terminator while leaving internal line terminators
intact. They do this because the "actual" string with which "expect"
will be compared is shaped the same way. However, this intent (having
internal line terminators, but no final line terminator) is not
necessarily obvious at first glance and may confuse casual readers. The
intent can be made more obvious by using `printf` instead, with which
line termination is stated clearly:

    printf "sixth\nthird"

In fact, many other tests in this script already use `printf` for
precisely this purpose, thus it is an established pattern. Therefore,
convert these tests to employ `printf`, as well.

While at it, modernize the tests to use test_cmp() to compare the
expected and actual output rather than using the semi-deprecated
`verbose test "$x" = "$y"`.

Subject: t5516: drop unnecessary subshell and command invocation

To create its "expect" file, this test pipes into `sort` the output of
`git for-each-ref` and a copy of that same output but with a minor
textual transformation applied. To do so, it employs a subshell and
commands `cat` and `sed` even though the same result can be accomplished
by `sed` alone (without a subshell).

Subject: t6300: make `%(raw:size) --shell` test more robust

This test populates its `expect` file solely by appending content but
fails to ensure that the file starts out empty. The test succeeds only
because no earlier test populated a file of the exact same name, however
this is an accident waiting to happen. Make the test more robust by
ensuring that it contains exactly the intended content.

While at it, simplify the implementation via a straightforward `sed`
application and by avoiding dropping out of the single-quote context
within the test body (thus eliminating a hard-to-digest combination of
apostrophes and backslashes).

Subject: t9107: use shell parameter expansion to avoid breaking &&-chain

This test intentionally breaks the &&-chain when using `expr` to parse
"[<path>]:<ref>" since the pattern matching operation will return 1
(failure) when <path> is empty even though an empty <path> is legitimate
in this test and should not cause the test to fail. However, it is
possible to parse the input without breaking the &&-chain by using shell
parameter expansion (i.e. `${i%%...}`). Other ways to avoid the problem
would be `{ expr $i : ... ||:; }` or test_might_fail(), however,
parameter expansion seems simplest.

IMPLEMENTATION NOTE

The rewritten `if` expression:

    if test "$ref" = "${ref#refs/remotes/}"`; then continue; fi

is perhaps a bit subtle. At first glance, it looks like it will
`continue` the loop if $ref starts with "refs/remotes/", but in fact
it's the opposite: the loop will `continue` if $ref does not start with
"refs/remotes/".

In the original, `expr` would only match if the ref started with
"refs/remotes/", and $ref would end up empty if it didn't, so `test -z`
would `continue` the loop if the ref did not start with "refs/remotes/".

With parameter expansion, ${ref#refs/remotes/} attempts to strip
"refs/remotes/" from $ref. If it fails, meaning that $ref does not start
with "refs/remotes/", then the expansion will just be $ref unchanged,
and it will `continue` the loop. On the other hand, if stripping
succeeds, meaning that $ref begins with "refs/remotes/", then the
expansion will be the value of $ref with "refs/remotes/" removed, hence
`continue` will not be taken.

Subject: tests: use test_write_lines() to generate line-oriented output

Take advantage of test_write_lines() to generate line-oriented output
rather than using for-loops or a series of `echo` commands. Not only is
test_write_lines() a natural fit for such a task, but there is less
opportunity for a broken &&-chain.

From 74d2f5695dab4454097b2d1693f7206e8328724a Mon Sep 17 00:00:00 2001
From: Eric Sunshine <sunshine@sunshineco.com>
Date: Thu, 9 Dec 2021 00:11:06 -0500
Subject: tests: fix broken &&-chains in compound statements

The top-level &&-chain checker built into t/test-lib.sh causes tests to
magically exit with code 117 if the &&-chain is broken. However, it has
the shortcoming that the magic does not work within `{...}` groups,
`(...)` subshells, `$(...)` substitutions, or within bodies of compound
statements, such as `if`, `for`, `while`, `case`, etc. `chainlint.sed`
partly fills in the gap by catching broken &&-chains in `(...)`
subshells, but bugs can still lurk behind broken &&-chains in the other
cases.

Fix broken &&-chains in compound statements in order to reduce the
number of possible lurking bugs.

Subject: tests: fix broken &&-chains in `$(...)` command substitutions

The top-level &&-chain checker built into t/test-lib.sh causes tests to
magically exit with code 117 if the &&-chain is broken. However, it has
the shortcoming that the magic does not work within `{...}` groups,
`(...)` subshells, `$(...)` substitutions, or within bodies of compound
statements, such as `if`, `for`, `while`, `case`, etc. `chainlint.sed`
partly fills in the gap by catching broken &&-chains in `(...)`
subshells, but bugs can still lurk behind broken &&-chains in the other
cases.

Fix broken &&-chains in `$(...)` command substitutions in order to
reduce the number of possible lurking bugs.

Subject: tests: apply modern idiom for signaling test failure

Simplify the way these tests signal failure by employing the modern
idiom of making the `if` or `case` statement resolve to false when an
error is detected.

Subject: tests: apply modern idiom for exiting loop upon failure

Rather than maintaining a flag indicating a failure within a loop and
aborting the test when the loop ends if the flag is set, modern practice
is to signal the failure immediately by exiting the loop early via
`return 1` (or `exit 1` if inside a subshell). Simplify these loops by
following the modern idiom.

Subject: tests: simplify by dropping unnecessary `for` loops

Rather than manually looping over a set of items and plugging those
items into a template string which is printed repeatedly, achieve the
same effect by taking advantage of `printf` which loops over its
arguments automatically.

From db5875aa9fe056c2db3a463989091c5f70d6c8d1 Mon Sep 17 00:00:00 2001
From: Eric Sunshine <sunshine@sunshineco.com>

Subject: t0000-t3999: detect and signal failure within loop

Failures within `for` and `while` loops can go unnoticed if not detected
and signaled manually since the loop itself does not abort when a
contained command fails, nor will a failure necessarily be detected when
the loop finishes since the loop returns the exit code of the last
command it ran on the final iteration, which may not be the command
which failed. Therefore, detect and signal failures manually within
loops using the idiom `|| return 1` (or `|| exit 1` within subshells).

From cbe1d9d630e529d3dd240eacf3d1c9799fef702b Mon Sep 17 00:00:00 2001
From: Eric Sunshine <sunshine@sunshineco.com>
Date: Thu, 9 Dec 2021 00:11:13 -0500
Subject: t4000-t4999: detect and signal failure within loop

Failures within `for` and `while` loops can go unnoticed if not detected
and signaled manually since the loop itself does not abort when a
contained command fails, nor will a failure necessarily be detected when
the loop finishes since the loop returns the exit code of the last
command it ran on the final iteration, which may not be the command
which failed. Therefore, detect and signal failures manually within
loops using the idiom `|| return 1` (or `|| exit 1` within subshells).

Subject: t5000-t5999: detect and signal failure within loop

Failures within `for` and `while` loops can go unnoticed if not detected
and signaled manually since the loop itself does not abort when a
contained command fails, nor will a failure necessarily be detected when
the loop finishes since the loop returns the exit code of the last
command it ran on the final iteration, which may not be the command
which failed. Therefore, detect and signal failures manually within
loops using the idiom `|| return 1` (or `|| exit 1` within subshells).

From 0c51d6b4aec9f1959d148960cb55155b676cec78 Mon Sep 17 00:00:00 2001
From: Eric Sunshine <sunshine@sunshineco.com>

Subject: t6000-t9999: detect and signal failure within loop

Failures within `for` and `while` loops can go unnoticed if not detected
and signaled manually since the loop itself does not abort when a
contained command fails, nor will a failure necessarily be detected when
the loop finishes since the loop returns the exit code of the last
command it ran on the final iteration, which may not be the command
which failed. Therefore, detect and signal failures manually within
loops using the idiom `|| return 1` (or `|| exit 1` within subshells).
