Instead of dying there, let the caller high up in the callchain
notice the error and handle it (by dying, still).
The only caller of fast_forward_to(), do_pick_commit() already checks
the return value and passes it on to its callers, so its caller must
be already prepared to handle error returns, and with this step, we
make it notice an error return from this function.
So this is a safe conversion to make fast_forward_to() callable from
new callers that want it not to die, without changing the external
behaviour of anything existing.

Note that the function git_config_from_file(), called from

because the do_config_from_file() function sets die_on_error = 1). We do
not try to fix that here, as it would have larger ramifications on the
config code, and we also assume that we write the opts file
programmatically, hence any parse errors would be bugs.

Instead of dying there, let the caller high up in the callchain

There are two call sites of read_and_refresh_cache(), one of which is
pick_commits(), whose callers were already prepared to do the right
thing given an "error" return from it by an earlier patch, so the
conversion is safe.
The other one, sequencer_pick_revisions() was also prepared to relay
an error return back to its caller in all remaining cases in an
earlier patch.

The recursive merge machinery accumulates its output in an output
buffer, to be flushed at the end of merge_recursive(). At this point,
we forgot to release the output buffer.
When calling merge_trees() (i.e. the non-recursive part of the recursive
merge) directly, the output buffer is never flushed because the caller
may be merge_recursive() which wants to flush the output itself.
For the same reason, merge_trees() cannot release the output buffer: it
may still be needed.
Forgetting to release the output buffer did not matter much when running
git-checkout, or git-merge-recursive, because we exited after the
operation anyway. Ever since cherry-pick learned to pick a commit range,
however, this memory leak had the potential of becoming a problem.

A helper function that takes the contents of a commit object and
finds its subject line did not ignore leading blank lines, as is
commonly done by other codepaths. Make it ignore leading blank
lines to match.

reset --hard: skip blank lines when reporting the commit subject
sequencer: use skip_blank_lines() to find the commit subject
commit -C: skip blank lines at the beginning of the message
commit.c: make find_commit_subject() more robust

Previously, callers of merge_trees() or merge_recursive() expected that
code to die() with an error message. This used to be okay because we
called those commands from scripts, and had a chance to print out a
message in case the command failed fatally (read: with exit code 128).
As scripting incurs its own set of problems (portability, speed,
idiosyncrasies of different shells, limited data structures leading to
inefficient code), we are converting more and more of these scripts into
builtins, using library functions directly.
We already tried to use merge_recursive() directly in the builtin
git-am, for example. Unfortunately, we had to roll it back temporarily
because some of the code in merge-recursive.c still deemed it okay to
call die(), when the builtin am code really wanted to print out a useful
advice after the merge failed fatally. In the next commits, we want to
fix that.
The code touched by this commit expected merge_trees() to die() with
some useful message when there is an error condition, but merge_trees()
is going to be improved by converting all die() calls to return error()
instead (i.e. return value -1 after printing out the message as before),
so that the caller can react more flexibly.
This is a step to prepare for the version of merge_trees() that no
longer dies, even if we just imitate the previous behavior by calling
exit(128): this is what callers of e.g. `git merge` have come to expect.
Note that the callers of the sequencer (revert and cherry-pick) already
fail fast even for the return value -1; The only difference is that they
now get a chance to say "<command> failed".
A caller of merge_trees() might want handle error messages themselves
(or even suppress them). As this patch is already complex enough, we
leave that change for a later patch.

Mark entire sentences of error message rather than assembling one using
placeholders (e.g. "Cannot %s during a %s").
That would facilitate translation work because it is easier to translate
a entire sentence than translating pieces. We would have better
translations at the expense of source code verbosity.
Moreover, translators can now 1) translate the terms "revert" and
"cherry-pick" if they please 2) have more leeway to adapt their
translations.

For a commit with sha1 "1234abcd" and subject "foo", this
function produces a struct with three strings:
1. "foo"
2. "1234abcd... foo"
3. "parent of 1234abcd... foo"
It takes advantage of the fact that these strings are
subsets of each other, and allocates only _one_ string, with
pointers into the various parts. Unfortunately, this makes
the string allocation complicated and hard to follow.
Since we keep only one of these in memory at a time, we can
afford to simply allocate three strings. This lets us build
on tools like xstrfmt and avoid manual computation.
While we're here, we can also drop the ad-hoc
reimplementation of get_git_commit_encoding(), and simply
call that function.

The strbuf_getline() interface allows a byte other than LF or NUL as
the line terminator, but this is only because I wrote these
codepaths anticipating that there might be a value other than NUL
and LF that could be useful when I introduced line_termination long
time ago. No useful caller that uses other value has emerged.
By now, it is clear that the interface is overly broad without a
good reason. Many codepaths have hardcoded preference to read
either LF terminated or NUL terminated records from their input, and
then call strbuf_getline() with LF or NUL as the third parameter.
This step introduces two thin wrappers around strbuf_getline(),
namely, strbuf_getline_lf() and strbuf_getline_nul(), and
mechanically rewrites these call sites to call either one of
them. The changes contained in this patch are:
* introduction of these two functions in strbuf.[ch]
* mechanical conversion of all callers to strbuf_getline() with
either '\n' or '\0' as the third parameter to instead call the
respective thin wrapper.
After this step, output from "git grep 'strbuf_getline('" would
become a lot smaller. An interim goal of this series is to make
this an empty set, so that we can have strbuf_getline_crlf() take
over the shorter name strbuf_getline().

To prepare for allowing a different "ref" backend to be plugged in

One of the most common uses of git_path() is to pass a
constant, like git_path("MERGE_MSG"). This has two
drawbacks:
1. The return value is a static buffer, and the lifetime
is dependent on other calls to git_path, etc.
2. There's no compile-time checking of the pathname. This
is OK for a one-off (after all, we have to spell it
correctly at least once), but many of these constant
strings appear throughout the code.
This patch introduces a series of functions to "memoize"
these strings, which are essentially globals for the
lifetime of the program. We compute the value once, take
ownership of the buffer, and return the cached value for
subsequent calls. cache.h provides a helper macro for
defining these functions as one-liners, and defines a few
common ones for global use.
Using a macro is a little bit gross, but it does nicely
document the purpose of the functions. If we need to touch
them all later (e.g., because we learned how to change the
git_dir variable at runtime, and need to invalidate all of
the stored values), it will be much easier to have the
complete list.
Note that the shared-global functions have separate, manual
declarations. We could do something clever with the macros
(e.g., expand it to a declaration in some places, and a
declaration _and_ a definition in path.c). But there aren't
that many, and it's probably better to stay away from
too-magical macros.
Likewise, if we abandon the C preprocessor in favor of
generating these with a script, we could get much fancier.
E.g., normalizing "FOO/BAR-BAZ" into "git_path_foo_bar_baz".
But the small amount of saved typing is probably not worth
the resulting confusion to readers who want to grep for the
function's definition.

"git cherry-pick" used to clean-up the log message even when it is
merely replaying an existing commit. It now replays the message
verbatim unless you are editing the message of resulting commits.
* mg/sequencer-commit-messages-always-verbatim:
sequencer: preserve commit messages
|
|
sequencer calls "commit" with default options, which implies
"--cleanup=default" unless the user specified something else in their
config. This leads to cherry-picked commits getting a cleaned up commit
message, which is usually not an intended side-effect.
Make the sequencer use "--cleanup=verbatim" so that it preserves commit
messages independent of the default, unless the user has set config for "commit"
or the message is amended with -s or -x.

(i.e. explaining how you resolved conflicts is much more important
than mentioning what you did to every paths involved in the commit).
But that still does not make this hint a part of the log message
proper, and not showing it as a comment is inviting mistakes.
Note that we still notice "Conflicts:" followed by list of indented
pathnames as an old-style cruft and insert a new Signed-off-by:
before it. This is so that "commit --amend -s" adds the new S-o-b
at the right place when used on an older commit.

Two identical loops in suggest_conflicts() in merge, and
do_recursive_merge() in sequencer, can use a single helper function
extracted from the latter that prepares the "Conflicts:" hint that
is meant to remind the user the paths for which merge conflicts had
to be resolved to write a better commit log message.

resolve_ref_unsafe takes a boolean argument for reading (a nonexistent ref
resolves successfully for writing but not for reading). Change this to be
a flags field instead, and pass the new constant RESOLVE_REF_READING when
we want this behaviour.
While at it, swap two of the arguments in the function to put output
arguments at the end. As a nice side effect, this ensures that we can
catch callers that were unaware of the new API so they can be audited.
Give the wrapper functions resolve_refdup and read_ref_full the same
treatment for consistency.
