Junio C Hamano [Sun, 20 Jul 2008 07:21:38 +0000 (00:21 -0700)]
"needs update" considered harmful

"git update-index --refresh", "git reset" and "git add --refresh" have
reported paths that have local modifications as "needs update" since the
beginning of git.

Although this is logically correct in that you need to update the index at
that path before you can commit that change, it is now becoming more and
more clear, especially with the continuous push for user friendliness
since 1.5.0 series, that the message is suboptimal.  After all, the change
may be something the user might want to get rid of, and "updating" would
be absolutely a wrong thing to do if that is the case.

I prepared two alternatives to solve this.  Both aim to reword the message
to more neutral "locally modified".

This patch is a more intrusive variant that changes the message for only
Porcelain commands ("add" and "reset") while keeping the plumbing
"update-index" intact.

git-add --all: add all files

People sometimes find that "git add -u && git add ." are 13 keystrokes too
many.  This reduces it by nine.

The support of this has been very low priority for me personally, because
I almost never do "git add ." in a directory with already tracked files,
and in a new directory, there is no point saying "git add -u".

However, for two types of people (that are very different from me), this
mode of operation may make sense and there is no reason to leave it
unsupported.  That is:

 (1) If you are extremely well disciplined and keep perfect .gitignore, it
     always is safe to say "git add ."; or

 (2) If you are extremely undisciplined and do not even know what files
     you created, and you do not very much care what goes in your history,
     it does not matter if "git add ." included everything.

So there it is, although I suspect I will not use it myself, ever.

It will be too much of a change that is against the expectation of the
existing users to allow "git commit -a" to include untracked files, and
it would be inconsistent if we named this new option "-a", so the short
option is "-A".  We _might_ want to later add "git commit -A" but that is

builtin-add.c: restructure the code for maintainability

The implementation of "git add" has four major codepaths that are mutually
exclusive:

 - if "--interactive" or "--patch" is given, spawn "git add--interactive"
   and exit without doing anything else.  Otherwise things are handled
   internally in this C code;

 - if "--update" is given, update the modified files and exit without
   doing anything else;

 - if "--refresh" is given, do refresh and exit without doing anything
   else;

 - otherwise, find the paths that match pathspecs and stage their
   contents.

It led to an unholy mess in the code structure; each of the latter three
codepaths has a separate call to read_cache(), even though they are all
about "read the current index, update it and write it back", and logically
they should read the index once _anyway_.

This cleans up the latter three cases by introducing a pair of helper
variables:

 - "add_new_files" is set if we need to scan the working tree for paths
   that match the pathspec.  This variable is false for "--update" and
   "--refresh", because they only work on already tracked files.

 - "require_pathspec" is set if the user must give at least one pathspec.
   "--update" does not need it but all the other cases do.

This is in preparation for introducing a new option "--all", that does the
equivalent of "git add -u && git add ." (aka "addremove").

index-pack: Honor core.deltaBaseCacheLimit when resolving deltas

If we are trying to resolve deltas for a long delta chain composed
of multi-megabyte objects we can easily run into requiring 500M+
of memory to hold each object in the chain on the call stack while
we recurse into the dependent objects and resolve them.

We now use a simple delta cache that discards objects near the
bottom of the call stack first, as they are the most least recently
used objects in this current delta chain.  If we recurse out of a
chain we may find the base object is no longer available, as it was
free'd to keep memory under the deltaBaseCacheLimit.  In such cases
we must unpack the base object again, which will require recursing
back to the root of the top of the delta chain as we released that
root first.

The astute reader will probably realize that we can still exceed
the delta base cache limit, but this happens only if the most
recent base plus the delta plus the inflated dependent sum up to
more than the base cache limit.  Due to the way patch_delta is
currently implemented we cannot operate in less memory anyway.

This however means that we must add the missing base object to the end of
