Ever since 66a155b (Enable output buffering in merge-recursive.,
2007-01-14), we had a problem: When the merge failed in a fatal way, all
regular output was swallowed because we called die() and did not get a
chance to drain the output buffers.
To fix this, several modifications were necessary:
- we needed to stop die()ing, to give callers a chance to do something
when an error occurred (in this case, flush the output buffers),
- we needed to delay printing the error message so that the caller can
print the buffered output before that, and
- we needed to make sure that the output buffers are flushed even when
the return value indicates an error.
The first two changes were introduced through earlier commits in this
patch series, and this commit addresses the third one.

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.

Since 66a155b (Enable output buffering in merge-recursive., 2007-01-14),
we already accumulate the output in a buffer. The idea was to avoid
interfering with the progress output that goes to stderr, which is
unbuffered, when we write to stdout, which is buffered.
We extend that buffering to allow the caller to handle the output
(possibly suppressing it). This will help us when extending the
sequencer to do rebase -i's brunt work: it does not want the picks to
print anything by default but instead determine itself whether to print
the output or not.
Note that we also redirect the error messages into the output buffer
when the caller asked not to flush the output buffer, for two reasons:
1) to retain the correct output order, and 2) to allow the caller to
suppress *all* output.

In 66a155b (Enable output buffering in merge-recursive., 2007-01-14), we
changed the code such that it prints the output in one go, to avoid
interfering with the progress output.
Let's make sure that the same holds true when outputting the commit
title: previously, we used several printf() statements to stdout and
assumed that stdout's buffer is large enough to hold the entire
commit title.
Apart from making that speculation unnecessary, we change the code to
add the message to the output buffer before flushing for another reason:
the next commit will introduce a new level of output buffering, where
the caller can request the output not to be flushed, but to be retained
for further processing.
This latter feature will be needed when teaching the sequencer to do
rebase -i's brunt work: it wants to control the output of the
cherry-picks (i.e. recursive merges).

The data structure passed to the recursive merge machinery has a feature
where the caller can ask for the output to be buffered into a strbuf, by
setting the field 'buffer_output'.
Previously, we died without flushing, losing accumulated output. With
this patch, we show the output first, and only then print the error
message.
Currently, the only user of that buffering is merge_recursive() itself,
to avoid the progress output to interfere.
In the next patches, we will introduce a new buffer_output mode that
forces merge_recursive() to retain the output buffer for further
processing by the caller. If the caller asked for that, we will then
also write the error messages into the output buffer. This is necessary
to give the caller more control not only how to react in case of errors
but also control how/if to display the error messages.

Last October, we had to change this code to run `git merge-recursive`
in a child process: git-am wants to print some helpful advice when the
merge failed, but the code in question was not prepared to return, it
die()d instead.
We are finally at a point when the code *is* prepared to return errors,
and can avoid the child process again.
This reverts commit c63d4b2 (am -3: do not let failed merge from
completing the error codepath, 2015-10-09), with the necessary changes
to adjust for the fact that Git's source code changed in the meantime
(such as: using OIDs instead of hashes in the recursive merge, and a
removed gender bias).
Note: the code now calls merge_recursive_generic() again. Unlike
merge_trees() and merge_recursive(), this function returns 0 upon success,
as most of Git's functions. Therefore, the error value -1 naturally is
handled correctly, and we do not have to take care of it specifically.

The recursive merge machinery is supposed to be a library function, i.e.
it should return an error when it fails. Originally the functions were
part of the builtin "merge-recursive", though, where it was simpler to
call die() and be done with error handling.
The existing callers were already prepared to detect negative return
values to indicate errors and to behave as previously: exit with code 128
(which is the same thing that die() does, after printing the message).

We are about to libify the recursive merge machinery, where we only
die() in case of a bug or memory contention. To that end, we must heed
negative return values as indicating errors.
This requires our functions to be careful to pass through error
conditions in call chains, and for quite a few functions this means
that they have to return values to begin with.
The next step will be to convert the places where we currently die() to
return negative values (read: -1) instead.
Note that we ignore errors reported by make_room_for_path(), consistent
with the previous behavior (update_file_flags() used the return value of
make_room_for_path() only to indicate an early return, but not a fatal
error): if the error is really a fatal error, we will notice later; If
not, it was not that serious a problem to begin with. (Witnesses in
favor of this reasoning are t4151-am-abort and t7610-mergetool, which
would start failing if we stopped on errors reported by
make_room_for_path()).
Also note: while this patch makes the code slightly less readable in
update_file_flags() (we introduce a new "goto free_buf;" instead of
an explicit "free(buf); return;"), it is a preparatory change for
the next patch where we will convert all of the die() calls in the same
function to go through the free_buf return path instead.

It is technically allowed, as per C89, for functions' return type to
be complete structs (i.e. *not* just pointers to structs).
However, it was just an oversight of this developer when converting
Python code to C code in 6d297f8 (Status update on merge-recursive in
C, 2006-07-08) which introduced such a return type.
Besides, by converting this construct to pass in the struct, we can now
start returning a value that can indicate errors in future patches. This
will help the current effort to libify merge-recursive.c.

There are a couple of places where return values never indicated errors
before, as we simply died instead of returning.
But now negative return values mean that there was an error and we have to
abort the operation. Let's do exactly that.

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.

It can be puzzling to see that was_tracked() asks to get an index entry
by name, but does not take a negative return value for an answer.
The reason we have to do this is that cache_name_pos() only looks for
entries in stage 0, even if nobody asked for any stage in particular.
Let's rewrite the logic a little bit, to handle the easy case early: if
cache_name_pos() returned a non-negative position, we know it is a match,
and we do not even have to compare the name again (cache_name_pos() did
that for us already). We can say right away: yes, this file was tracked.
Only if there was no exact match do we need to look harder for any
matching entry in stage 2.

While working on the patch series that avoids die()ing in recursive
merges, the issue came up that bug reports (i.e. die("BUG: ...")
constructs) should never be translated, as the target audience is the
Git developer community, not necessarily the current user, and hence
a translated message would make it *harder* to address the problem.
So let's stop translating the obvious ones. As it is really, really
outside the purview of this patch series to see whether there are more
die() statements that report bugs and are currently translated, that
task is left for another day and patch.

The vast majority of error messages in Git's source code which report a
bug use the convention to prefix the message with "BUG:".
As part of cleaning up merge-recursive to stop die()ing except in case of
detected bugs, let's just make the remainder of the bug reports consistent
with the de facto rule.

It was noticed by Brendan Forster last October that the builtin `git am`
regressed on that. Our hot fix reverted to spawning the recursive merge
instead of using it as a library function.
As we are about to revert that hot fix, after making the recursive merge a
true library function (i.e. a function that does not die() in case of
"normal" errors), let's add a test that verifies that we do not regress on
the same problem which made the hot fix necessary in the first place.

When blaming files, changes in the work tree are taken into account
and displayed as being "Not Committed Yet".
However, when blaming a file that is not known to the current HEAD,
git blame fails with `no such path 'foo' in HEAD`, even when the file
was git add'ed.
Allowing such a blame is useful when the new file added to the index
(not yet committed) was created by renaming an existing file. It
also is useful when the new file was created from pieces already in
HEAD, moved or copied from other files and blaming with copy
detection (i.e. "-C").

When reporting broken links between commits/trees/blobs, it would be
quite helpful at times if the user would be told how the object is
supposed to be reachable.
With the new --name-objects option, git-fsck will try to do exactly
that: name the objects in a way that shows how they are reachable.
For example, when some reflog got corrupted and a blob is missing that
should not be, the user might want to remove the corresponding reflog
entry. This option helps them find that entry: `git fsck` will now
report something like this:
broken link from tree b5eb6ff... (refs/stash@{<date>}~37:)
to blob ec5cf80...

If fsck_options->name_objects is initialized, and if it already has
name(s) for the object(s) that are to be the starting point(s) for
fsck_walk(), then that function will now add names for the objects
that were walked.
This will be highly useful for teaching git-fsck to identify root causes
for broken links, which is the task for the next patch in this series.
Note that this patch opts for decorating the objects with plain strings
instead of full-blown structs (à la `struct rev_name` in the code of
the `git name-rev` command), for several reasons:
- the code is much simpler than if it had to work with structs that
describe arbitrarily long names such as "master~14^2~5:builtin/am.c",
- the string processing is actually quite light-weight compared to the
rest of fsck's operation,
- the caller of fsck_walk() is expected to provide names for the
starting points, and using plain and simple strings is just the
easiest way to do that.

If a subdirectory contains nothing but i-t-a entries, we generate an
empty tree object and add it to its parent tree. Which is wrong. Such
a subdirectory should not be added.
Note that this has a cascading effect. If subdir 'a/b/c' contains
nothing but i-t-a entries, we ignore it. But then if 'a/b' contains
only (the non-existing) 'a/b/c', then we should ignore 'a/b' while
building 'a' too. And it goes all the way up to top directory.

Commit 3cf773e (cache-tree: fix writing cache-tree when CE_REMOVE is
present - 2012-12-16) skips i-t-a entries when building trees objects
from the index. Unfortunately it may skip too much.
The code in question checks if an entry is an i-t-a one, then no tree
entry will be written. But it does not take into account that
directories can also be written with the same code. Suppose we have
this in the index.
a-file
subdir/file1
subdir/file2
subdir/file3
the-last-file
We write an entry for a-file as normal and move on to subdir/file1,
where we realize the entry name for this level is simply just
"subdir", write down an entry for "subdir" then jump three items ahead
to the-last-file.
That is what happens normally when the first file in subdir is not an
i-t-a entry. If subdir/file1 is an i-t-a, because of the broken
condition in this code, we still think "subdir" is an i-t-a file and
not writing "subdir" down and jump to the-last-file. The result tree
now only has two items: a-file and the-last-file. subdir should be
there too (even though it only records two sub-entries, file2 and
file3).
If the i-t-a entry is subdir/file2 or subdir/file3, this is not a
problem because we jump over them anyway. Which may explain why the
bug is hidden for nearly four years.
Fix it by making sure we only skip i-t-a entries when the entry in
question is actual an index entry, not a directory.

"git fetch http://user:pass@host/repo..." scrubbed the userinfo
part, but "git push" didn't.

t5541: fix url scrubbing test when GPG is not set

When the GPG prereq is not set, we do not run test 34. That
test changes the directory of the test script as a side
effect (something we usually frown on, but which matches the
style of the rest of this script). When test 35 (the
url-scrubbing test) runs, it expects to be in the directory
from test 34. If it's not, the test fails; we are in a
different sub-repo, our test-commit is built on a different
history, and the push becomes a non-fast-forward.
We can fix this by unconditionally moving to the directory
we expect (again, against our usual style but matching how
the rest of the script operates).
As an additional protection, let's also switch from "make a
new commit and push to master" to just "push to a new
branch". We don't care about the branch name; we just want
_some_ ref update to trigger the status output. Pushing to a
new branch is less likely to run into problems with
force-updates, changing the checked-out branch, etc.

Commit 47abd85 (fetch: Strip usernames from url's before
storing them, 2009-04-17) taught fetch to anonymize URLs.
The primary purpose there was to avoid sticking passwords in
merge-commit messages, but as a side effect, we also avoid
printing them to stderr.
The push side does not have the merge-commit problem, but it
probably should avoid printing them to stderr. We can reuse
the same anonymizing function.
Note that for this to come up, the credentials would have to
appear either on the command line or in a git config file,
neither of which is particularly secure. So people _should_
be switching to using credential helpers instead, which
makes this problem go away. But that's no excuse not to
improve the situation for people who for whatever reason end
up using credentials embedded in the URL.

A few test-helpers have Makefile dependencies on specific
object files. But since these files are part of libgit.a
(which all of the helpers link against), the inclusion is
simply redundant.
These were once necessary, but became redundant due to
5c5ba73 (Makefile: Use generic rule to build test programs,
2007-05-31), which added the $(GITLIBS) dependency (but
didn't prune the extra dependency lines). Later commits then
cargo-culted the practice (e.g., b4285c7).
Note that we _do_ need to leave the dependencies on the svn
library, as that is not part of the usual link command.

When merge_recursive() decides what the correct blob object merge
result for a path should be, it uses update_file_flags() helper
function to write it out to a working tree file and then calls
add_cacheinfo(). The add_cacheinfo() function in turn calls
make_cache_entry() to create a new cache entry to replace the
higher-stage entries for the path that represents the conflict.
The make_cache_entry() function calls refresh_cache_entry() to fill
in the cached stat information. To mark a cache entry as
up-to-date, the data is re-read from the file in the working tree,
and goes through convert_to_git() conversion to be compared with the
blob object name the new cache entry records.
It is important to note that this happens while the higher-stage
entries, which are going to be replaced with the new entry, are
still in the index. Unfortunately, the convert_to_git() conversion
has a misguided "safer crlf" mechanism baked in, and looks at the
existing cache entry for the path to decide how to convert the
contents in the working tree file. If our side (i.e. stage#2)
records a text blob with CRLF in it, even when the system is
configured to record LF in blobs and convert them to CRLF upon
checkout (and back to LF upon checkin), the "safer crlf" mechanism
stops us doing so.
This especially poses a problem during a renormalizing merge, where
the merge result for the path is computed by first "normalizing" the
blobs involved in the merge by using convert_to_working_tree()
followed by convert_to_git() with "safer crlf" disabled. The merge
result that is computed correctly and fed to add_cacheinfo() via
update_file_flags() does _not_ match what refresh_cache_entry() sees
by converting the working tree file via convert_to_git().
We can work this around by not refreshing the new cache entry in
make_cache_entry() called by add_cacheinfo(). After add_cacheinfo()
adds the new entry, we can call refresh_cache_entry() on that,
knowing that addition of this new cache entry would have removed the
stale cache entries that had CRLF in stage #2 that were carried over
before the renormalizing merge started and will not interfere with
the correct recording of the result.
The test update was taken from a series by Torsten Bögershausen
that attempted to fix this with a different approach.

Before this change,
$ echo "* text=auto" >.gitattributes
$ echo "* eol=crlf" >>.gitattributes
would have the same effect as
$ echo "* text" >.gitattributes
$ git config core.eol crlf
Since the 'eol' attribute had higher priority than 'text=auto', this may
corrupt binary files and is not what most users expect to happen.
Make the 'eol' attribute to obey 'text=auto' and now
$ echo "* text=auto" >.gitattributes
$ echo "* eol=crlf" >>.gitattributes
behaves the same as
$ echo "* text=auto" >.gitattributes
$ git config core.eol crlf
In other words,
$ echo "* text=auto eol=crlf" >.gitattributes
has the same effect as
$ git config core.autocrlf true
and
$ echo "* text=auto eol=lf" >.gitattributes
has the same effect as
$ git config core.autocrlf input
