t3419: prevent failure when run with EXPENSIVE
This test runs a function which itself runs several assertions. The
last of these assertions cleans up the .git/rebase-apply directory,
since when run with EXPENSIVE set, the function is invoked a second time
to run the same tests with a larger data set.
However, as of 2ac0d6273f ("rebase: change the default backend from "am"
to "merge"", 2020-02-15), the default backend of rebase has changed, and
cleaning up the rebase-apply directory has no effect: it no longer
exists, since we're using rebase-merge instead.
Since we don't really care which rebase backend is in use, let's just
use the command "git rebase --quit", which will do the right thing
regardless.

git-gui: create a new namespace for chord script evaluation
Evaluating the script in the same namespace as the chord itself creates
potential for variable name collision. And in that case the script would
unknowingly use the chord's variables.
For example, say the script has a variable called 'is_completed', which
also exists in the chord's namespace. The script then calls 'eval' and
sets 'is_completed' to 1 thinking it is setting its own variable,
completely unaware of how the chord works behind the scenes. This leads
to the chord never actually executing because it sees 'is_completed' as
true and thinks it has already completed.
Avoid the potential collision by creating a separate namespace for the
script that is a child of the chord's namespace.

git-gui: reduce Tcl version requirement from 8.6 to 8.5
On some MacOS distributions like High Sierra, Tcl 8.5 is shipped by
default. This makes git-gui error out at startup because of the version
mismatch.
The only part that requires Tcl 8.6 is SimpleChord, which depends on
TclOO. So, don't use it and use our homegrown class.tcl instead.
This means some slight syntax changes. Since class.tcl doesn't have an
"unknown" method like TclOO does, we can't just call '$note', but have
to use '$note activate' instead. The constructor now needs a proper
namespace qualifier. Update the documentation to reflect the new syntax.
As of now, the only part of git-gui that needs Tcl 8.5 is a call to
'apply' in lib/index.tcl::lambda. Keep using it until someone shows up
shouting that their OS ships with 8.4 only. Then we would have to look
into implementing it in pure Tcl.

t6022, t6046: fix flaky files-are-updated checks
Several tests wanted to verify that files were actually modified by a
merge, which it would do by checking that the mtime was updated. In
order to avoid problems with the merge completing so fast that the mtime
at the beginning and end of the operation was the same, these tests
would first set the mtime of a file to something "old". This "old"
value was usually determined as current system clock minus one second,
truncated to the nearest integer. Unfortunately, it appears the system
clock and filesystem clock are different and comparing across the two
runs into race problems resulting in flaky tests.
From https://stackoverflow.com/questions/14392975/timestamp-accuracy-on-ext4-sub-millsecond:
date will call the gettimeofday system call which will always return
the most accurate time available based on the cached kernel time,
adjusted by the CPU cycle time if available to give nanosecond
resolution. The timestamps stored in the file system however, are
only based on the cached kernel time. ie The time calculated at the
last timer interrupt.
No, this depends on clock granularity. For example, gettimeofday()
can return times in microseconds on my system, but ext4 rounds
timestamps down to the previous ~10ms (but not exactly 10ms)
increment, with the surprising result that a newly-created file is
almost always created in the past:
So, instead of trying to compare across what are effectively two
different clocks, just avoid using the system clock. Any new updates to
files have to give an mtime at least as big as what is already in the
file, so we could define "old" as one second before the mtime found in
the file before the merge starts. But, to avoid problems with leap
seconds, ntp updates, filesystems that only provide two second
resolution, and other such weirdness, let's just pick an hour before the
mtime found in the file before the merge starts.
Also, clarify in one test where we check the mtime of different files
that it really was intentional. I totally forgot the reasons for that
and assumed it was a bug when asked.

fsck: detect gitmodules URLs with embedded newlines
The credential protocol can't handle values with newlines. We already
detect and block any such URLs from being used with credential helpers,
but let's also add an fsck check to detect and block gitmodules files
with such URLs. That will let us notice the problem earlier when
transfer.fsckObjects is turned on. And in particular it will prevent bad
objects from spreading, which may protect downstream users running older
versions of Git.
We'll file this under the existing gitmodulesUrl flag, which covers URLs
with option injection. There's really no need to distinguish the exact
flaw in the URL in this context. Likewise, I've expanded the description
of t7416 to cover all types of bogus URLs.

credential: detect unrepresentable values when parsing urls
The credential protocol can't represent newlines in values, but URLs can
embed percent-encoded newlines in various components. A previous commit
taught the low-level writing routines to die() when encountering this,
but we can be a little friendlier to the user by detecting them earlier
and handling them gracefully.
This patch teaches credential_from_url() to notice such components,
issue a warning, and blank the credential (which will generally result
in prompting the user for a username and password). We blank the whole
credential in this case. Another option would be to blank only the
invalid component. However, we're probably better off not feeding a
partially-parsed URL result to a credential helper. We don't know how a
given helper would handle it, so we're better off to err on the side of
matching nothing rather than something unexpected.
The die() call in credential_write() is _probably_ impossible to reach
after this patch. Values should end up in credential structs only by URL
parsing (which is covered here), or by reading credential protocol input
(which by definition cannot read a newline into a value). But we should
definitely keep the low-level check, as it's our final and most accurate
line of defense against protocol injection attacks. Arguably it could
become a BUG(), but it probably doesn't matter much either way.
Note that the public interface of credential_from_url() grows a little
more than we need here. We'll use the extra flexibility in a future
patch to help fsck catch these cases.

t/lib-credential: use test_i18ncmp to check stderr
The credential tests have a "check" function which feeds some input to
git-credential and checks the stdout and stderr. We look for exact

the credential protocol. But for stderr, we may be showing various
diagnostic messages, or the prompts fed to the askpass program, which
could be translated. Let's mark them as such.

credential: avoid writing values with newlines
The credential protocol that we use to speak to helpers can't represent
values with newlines in them. This was an intentional design choice to
keep the protocol simple, since none of the values we pass should
generally have newlines.
However, if we _do_ encounter a newline in a value, we blindly transmit
it in credential_write(). Such values may break the protocol syntax, or
worse, inject new valid lines into the protocol stream.
The most likely way for a newline to end up in a credential struct is by
decoding a URL with a percent-encoded newline. However, since the bug
occurs at the moment we write the value to the protocol, we'll catch it
there. That should leave no possibility of accidentally missing a code
path that can trigger the problem.
At this level of the code we have little choice but to die(). However,
since we'd not ever expect to see this case outside of a malicious URL,
that's an acceptable outcome.

Back when "git am" was written, it was not considered a bug that the

but honestly, I'd have to say that it is a bug in "git am" in that
over time it wasn't adjusted to the new world order where we
encourage users to describe what they did when the automation
hiccuped by opening an editor. These days, even when automation
worked well (e.g. a clean auto-merge with "git merge"), we open an
editor. The world has changed, and so should the expectations.
Junio also suggested providing a workaround such as allowing --no-edit
together with git rebase --continue, but that should probably be done in

Unfortunately, this also means we bypassed the clearing of the
