might be obscured by other windows. The user might be left staring at
the original Git terminal window without even realizing that s/he needs
to interact with another window before Git can proceed. To this user Git
appears hanging.

Print a message that Git is waiting for editor input in the original
terminal and get rid of it when the editor returns, if the terminal
supports erasing the last line.  Also, make sure that our message is
terminated with a whitespace so that any message the editor may show
upon starting up will be kept separate from our message.

Power users might not want to see this message or their editor might
already print such a message (e.g. emacsclient). Allow these users to
suppress the message by disabling the "advice.waitingForEditor" config.

The standard advise() function is not used here as it would always add

'gitmodules_config()' which ensured that the index was already populated
before entering the attribute subsystem.

Since the call to 'gitmodules_config()' was removed the index is no
longer being read so when the attribute system tries to read from the
in-memory index it doesn't find any ".gitattribute" entries effectively
ignoring any configured attributes.

Fix this by explicitly reading the index during the setup of diff-tree.

worktree: add --guess-remote flag to add subcommand

basename of the <path>, that matches the HEAD of whichever worktree we
were on when calling "git worktree add <path>".

It's sometimes useful to have 'git worktree add <path> behave more like
the dwim machinery in 'git checkout <new-branch>', i.e. check if the new
branch name, derived from the basename of the <path>, uniquely matches
the branch name of a remote-tracking branch, and if so check out that
branch and set the upstream to the remote-tracking branch.

Brandon Williams [Tue, 5 Dec 2017 00:07:34 +0000 (16:07 -0800)]
pathspec: only match across submodule boundaries when requested

Commit 74ed43711fd (grep: enable recurse-submodules to work on <tree>
objects, 2016-12-16) taught 'tree_entry_interesting()' to be able to
match across submodule boundaries in the presence of wildcards.  This is
done by performing literal matching up to the first wildcard and then
punting to the submodule itself to perform more accurate pattern
matching.  Instead of introducing a new flag to request this behavior,
commit 74ed43711fd overloaded the already existing 'recursive' flag in
'struct pathspec' to request this behavior.

This leads to a bug where whenever any other caller has the 'recursive'
flag set as well as a pathspec with wildcards that all submodules will
be indicated as matches.  One simple example of this is:

git init repo
cd repo

git init submodule
git -C submodule commit -m initial --allow-empty

touch "[bracket]"
git add "[bracket]"
git commit -m bracket
git add submodule
git commit -m submodule

git rev-list HEAD -- "[bracket]"

Fix this by introducing the new flag 'recurse_submodules' in 'struct
pathspec' and using this flag to determine if matches should be allowed
to cross submodule boundaries.

progress: set default delay threshold to 100%, not 0%

Commit 8aade107dd (progress: simplify "delayed" progress
API, 2017-08-19) dropped the parameter by which callers
could say "show my progress only if I haven't passed M%
progress after N seconds". The intent was to just show
nothing for 2 seconds, and then always progress after that.

But we flipped the logic in the wrapper: it sets M=0,
meaning that we'd almost _never_ show progress after 2
seconds, since we'd generally have made some progress. This
should have been 100%, not 0%.

We were fooled by existing calls like:

  start_progress_delay("foo", 0, 0, 2);

which behaved this way. The trick is that the first "0"
there is "how many items total", and there zero means "we
don't know". And without knowing that, we cannot compute a
completed percent at all, and we ignored the threshold
parameter entirely! Modeling our wrapper after that broke
callers which pass a non-zero value for "total".

We can switch to the intended behavior by using "100" in the
wrapper call.

Replace use of strbuf_addf() with strbuf_add() when enumerating

check the length and hex-values of the string before consuming
the path, we can prevent extra computation by using the lower-
level method.

One consumer of for_each_file_in_obj_subdir() is the abbreviation
code. OID abbreviations use a cached list of loose objects (per
object subdirectory) to make repeated queries fast, but there is
significant cache load time when there are many loose objects.

Most repositories do not have many loose objects before repacking,

objects. Profiling 'git log' performance in GitForWindows on a
GVFS-enabled repo with ~2.5 million loose objects revealed 12% of
the CPU time was spent in strbuf_addf().
