0940a76db6 pretty: get the correct encoding for --pretty:format=%e
parse_commit_header() provides the commit encoding for '%e' and it
reads it from the re-encoded message, which contains the new encoding,
not the original one in the commit object. This never happens because
--pretty=format:xxx never respects i18n.logoutputencoding. But that's
a different story.

Get the commit encoding from logmsg_reencode() instead.

The commit encoding is parsed by logmsg_reencode, there's no need for
the caller to re-parse it again. The reencoded message now has the new
encoding, not the original one. The caller would need to read commit

d226b14d47 git add: rework the logic to warn "git add <pathspec>..." default change
The earlier logic to warn against "git add subdir" that is run
without "-A" or "--no-all" was only to check any <pathspec> given
exactly spells a directory name that (still) exists on the
filesystem.  This had number of problems:

 * "git add '*dir'" (note that the wildcard is hidden from the
   shell) would not trigger the warning.

 * "git add '*.py'" would behave differently between the current
   version of Git and Git 2.0 for the same reason as "subdir", but
   would not trigger the warning.

 * "git add dir" for a submodule "dir" would just update the index
   entry for the submodule "dir" without ever recursing into it, and
   use of "-A" or "--no-all" would matter.  But the logic only
   checks the directory-ness of "dir" and gives an unnecessary
   warning.

Rework the logic to detect the case where the behaviour will be
different in Git 2.0, and issue a warning only when it matters.
Even with the code before this warning, "git add subdir" will have
to traverse the directory in order to find _new_ files the index
does not know about _anyway_, so we can do this check without adding
an extra pass to find if <pathspec> matches any removed file.

This essentially updates the "add_files_to_cache()" public API to
"update_files_in_cache()" API that is internal to "git add", because
with the "--all" option, the function is no longer about "adding"
paths to the cache, but is also used to remove them.

There are other callers of the former from "checkout" (used when
"checkout -m" prepares the temporary tree that represents the local
modifications to be merged) and "commit" ("commit --include" that
picks up local changes in addition to what is in the index).  Since
ADD_CACHE_IGNORE_ERRORS (aka "--no-all") is not used by either of
them, once dust settles after Git 2.0 and the warning becomes
unnecessary, we may want to unify these two functions again.

9cfa5126a0 cat-file: print tags raw for "cat-file -p"
When "cat-file -p" prints commits, it shows them in their
raw format, since git's format is already human-readable.
For tags, however, we print the whole thing raw except for
one thing: we convert the timestamp on the tagger line into a
human-readable date.

This dates all the way back to a0f15fa (Pretty-print tagger
dates, 2006-03-01). At that time there was no other way to
pretty-print a tag.  These days, however, neither of those
matters much. The normal way to pretty-print a tag is with
"git show", which is much more flexible than "cat-file -p".

Commit a0f15fa also built "verify-tag --verbose" (and
subsequently "tag -v") around the "cat-file -p" output.
However, that behavior was lost in commit 62e09ce (Make git
tag a builtin, 2007-07-20), and we went back to printing
the raw tag contents. Nobody seems to have noticed the bug
since then (and it is arguably a saner behavior anyway, as
it shows the actual bytes for which we verified the
signature).

Let's drop the tagger-date formatting for "cat-file -p". It
makes us more consistent with cat-file's commit
pretty-printer, and as a bonus, we can drop the hand-rolled
tag parsing code in cat-file (which happened to behave
inconsistently with the tag pretty-printing code elsewhere).

This is a change of output format, so it's possible that
some callers could considered this a regression. However,
the original behavior was arguably a bug (due to the
inconsistency with commits), likely nobody was relying on it
(even we do not use it ourselves these days), and anyone
relying on the "-p" pretty-printer should be able to expect
a change in the output format (i.e., while "cat-file" is
plumbing, the output format of "-p" was never guaranteed to
be stable).

1ece66bc9e run-command: use thread-aware die_is_recursing routine
If we die from an async thread, we do not actually exit the
program, but just kill the thread. This confuses the static
counter in usage.c's default die_is_recursing function; it
updates the counter once for the thread death, and then when
the main program calls die() itself, it erroneously thinks
we are recursing. The end result is that we print "recursion
detected in die handler" instead of the real error in such a
case (the easiest way to trigger this is having a remote
connection hang up while running a sideband demultiplexer).

This patch solves it by using a per-thread counter when the
async_die function is installed; we detect recursion in each
thread (including the main one), but they do not step on
each other's toes.

Other threaded code does not need to worry about this, as
they do not install specialized die handlers; they just let
a die() from a sub-thread take down the whole program.

Since we are overriding the default recursion-check
function, there is an interesting corner case that is not a
problem, but bears some explanation. Imagine the main thread
calls die(), and then in the die_routine starts an async
call. We will switch to using thread-local storage, which
starts at 0, for the main thread's counter, even though
the original counter was actually at 1. That's OK, though,
for two reasons:

  1. It would miss only the first level of recursion, and
     would still find recursive failures inside the async
     helper.

  2. We do not currently and are not likely to start doing
     anything as heavyweight as starting an async routine
     from within a die routine or helper function.

c19a490e37 usage: allow pluggable die-recursion checks
When any git code calls die or die_errno, we use a counter
to detect recursion into the die functions from any of the
helper functions. However, such a simple counter is not good
enough for threaded programs, which may call die from a
sub-thread, killing only the sub-thread (but incrementing
the counter for everyone).

Rather than try to deal with threads ourselves here, let's
just allow callers to plug in their own recursion-detection
function. This is similar to how we handle the die routine
(the caller plugs in a die routine which may kill only the
sub-thread).

70d26c6e76 read_revisions_from_stdin: make copies for handle_revision_arg
read_revisions_from_stdin() has passed pointers to its read buffer
down to handle_revision_arg() since its inception way back in 42cabc3
(Teach rev-list an option to read revs from the standard input.,
2006-09-05).  Even back then, this was a bug: through
add_pending_object, the argument was recorded in the object_array's
'name' field.

Fix it by making a copy whenever read_revisions_from_stdin() passes an
argument down the callchain.  The other caller runs handle_revision_arg()
on argv[], where it would be redundant to make a copy.

b793acf14c http: set curl FAILONERROR each time we select a handle
Because we reuse curl handles for multiple requests, the
setup of a handle happens in two stages: stable, global
setup and per-request setup. The lifecycle of a handle is
something like:

  1. get_curl_handle; do basic global setup that will last
     through the whole program (e.g., setting the user
     agent, ssl options, etc)

  2. get_active_slot; set up a per-request baseline (e.g.,
     clearing the read/write functions, making it a GET
     request, etc)

  3. perform the request with curl_*_perform functions

  4. goto step 2 to perform another request

Breaking it down this way means we can avoid doing global
setup from step (1) repeatedly, but we still finish step (2)
with a predictable baseline setup that callers can rely on.

Until commit 6d052d7 (http: add HTTP_KEEP_ERROR option,
2013-04-05), setting curl's FAILONERROR option was a global
setup; we never changed it. However, 6d052d7 introduced an
option where some requests might turn off FAILONERROR. Later
requests using the same handle would have the option
unexpectedly turned off, which meant they would not notice
http failures at all.

This could easily be seen in the test-suite for the
"half-auth" cases of t5541 and t5551. The initial requests
turned off FAILONERROR, which meant it was erroneously off
for the rpc POST. That worked fine for a successful request,
but meant that we failed to react properly to the HTTP 401
(instead, we treated whatever the server handed us as a
successful message body).

The solution is simple: now that FAILONERROR is a
per-request setting, we move it to get_active_slot to make
sure it is reset for each request.

ancestor operators e.g. foobar^2~2^2^2^2...^2~4 correctly.

* jk/show-branch-strbuf:
  show-branch: use strbuf instead of static buffer

  http: drop http_error function
  remote-curl: die directly with http error messages
  http: re-word http error message
  http: simplify http_error helper function
  remote-curl: consistently report repo url for http errors
  remote-curl: always show friendlier 404 message
  remote-curl: let servers override http 404 advice
  remote-curl: show server content on http errors

d809d050ff Merge branch 'tr/perl-keep-stderr-open'
Closing (not redirecting to /dev/null) the standard error stream is
not a very smart thing to do.  Later open may return file
descriptor #2 for unrelated purpose, and error reporting code may
write into them.

* tr/perl-keep-stderr-open:
  t9700: do not close STDERR
  perl: redirect stderr to /dev/null instead of closing

0aaf62b6e0 dir.c: git-status --ignored: don't scan the work tree twice
'git-status --ignored' still scans the work tree twice to collect
untracked and ignored files, respectively.

fill_directory / read_directory already supports collecting untracked and
ignored files in a single directory scan. However, the DIR_COLLECT_IGNORED
flag to enable this has some git-add specific side-effects (e.g. it
doesn't recurse into ignored directories, so listing ignored files with
--untracked=all doesn't work).

The DIR_SHOW_IGNORED flag doesn't list untracked files and returns ignored
files in dir_struct.entries[] (instead of dir_struct.ignored[] as
DIR_COLLECT_IGNORED). DIR_SHOW_IGNORED is used all throughout git.

We don't want to break the existing API, so lets introduce a new flag
DIR_SHOW_IGNORED_TOO that lists untracked as well as ignored files similar
to DIR_COLLECT_FILES, but will recurse into sub-directories based on the
other flags as DIR_SHOW_IGNORED does.

In dir.c::read_directory_recursive, add ignored files to either
dir_struct.entries[] or dir_struct.ignored[] based on the flags. Also move
the DIR_COLLECT_IGNORED case here so that filling result lists is in a
common place.

In wt-status.c::wt_status_collect_untracked, use the new flag and read
results from dir_struct.ignored[]. Remove the extra fill_directory call.

builtin/check-ignore.c doesn't call fill_directory, setting the git-add
specific DIR_COLLECT_IGNORED flag has no effect here. Remove for clarity.

Update API documentation to reflect the changes.

Performance: with this patch, 'git-status --ignored' is typically as fast
as 'git-status'.

defd7c7b37 dir.c: git-status --ignored: don't scan the work tree three times
'git-status --ignored' recursively scans directories up to three times:

 1. To collect untracked files.

 2. To collect ignored files.

 3. When collecting ignored files, to check that an untracked directory
    that potentially contains ignored files doesn't also contain untracked
    files (i.e. isn't already listed as untracked).

Let's get rid of case 3 first.

Currently, read_directory_recursive returns a boolean whether a directory
contains the requested files or not (actually, it returns the number of
files, but no caller actually needs that), and DIR_SHOW_IGNORED specifies
what we're looking for.

To be able to test for both untracked and ignored files in a single scan,
we need to return a bit more info, and the result must be independent of
the DIR_SHOW_IGNORED flag.

Reuse the path_treatment enum as return value of read_directory_recursive.
Split path_handled in two separate values path_excluded and path_untracked
that don't change their meaning with the DIR_SHOW_IGNORED flag. We don't
need an extra value path_untracked_and_excluded, as directories with both
untracked and ignored files should be listed as untracked.

Rename path_ignored to path_none for clarity (i.e. "don't treat that path"
in contrast to "the path is ignored and should be treated according to
DIR_SHOW_IGNORED").

Replace enum directory_treatment with path_treatment. That's just another
enum with the same meaning, no need to translate back and forth.

In treat_directory, get rid of the extra read_directory_recursive call and
all the DIR_SHOW_IGNORED-specific code.

In read_directory_recursive, decide whether to dir_add_name path_excluded
or path_untracked paths based on the DIR_SHOW_IGNORED flag.

The return value of read_directory_recursive is the maximum path_treatment
of all files and sub-directories. In the check_only case, abort when we've
reached the most significant value (path_untracked).
