5f44324d88 core: log offset pack data accesses happened
In a workload other than "git log" (without pathspec nor any option that
causes us to inspect trees and blobs), the recency pack order is said to
cause the access jump around quite a bit. Add a hook to allow us observe
how bad it is.

"git config core.logpackaccess /var/tmp/pal.txt" will give you the log
in the specified file.

1c2c9bee1b config: die on error in command-line config
The error handling for git_config is somewhat confusing. We
collect errors from running git_config_from_file on the
various config files and carefully pass them back up. But
the two odd things are:

  1. We actually die on most errors in git_config_from_file.
     In fact, the only error we actually pass back up is if
     fopen() fails on the file.

  2. Most callers of git_config do not check the error
     return at all, but will continue if git_config reports
     an error.

When the code for "git -c core.foo=bar" was added, it
dutifully passed errors up the call stack, only for them to
be eventually ignored. This makes it inconsistent with the
file-parsing code, which will die when it sees malformed
config. And it's somewhat unsafe, because it means an error
in parsing a typo like:

  git -c clean.requireforce=ture clean

will continue the command, ignoring the config the user
tried to give.

5bf6529aaa fix "git -c" parsing of values with equals signs
If you do something like:

  git -c core.foo="value with = in it" ...

we would split your option on "=" into three fields and
throw away the third one. With this patch we correctly take
everything after the first "=" as the value (keys cannot
have an equals sign in them, so the parsing is unambiguous).

924aaf3ef7 config.c: Make git_config() work correctly when called recursively
On Cygwin, this fixes a test failure in t3301-notes.sh (test 98,
"git notes copy --for-rewrite (disabled)").

The test failure is caused by a recursive call to git_config() which
has the effect of skipping to the end-of-file while processing the
"notes.rewriteref" config variable. Thus, any config variables that
appear after "notes.rewriteref" are simply ignored by git_config().
Also, we note that the original FILE handle is leaked as a result
of the recursive call.

The recursive call to git_config() is due to the "schizophrenic stat"
functions on cygwin, where one of two different implementations of
the l/stat functions is selected lazily, depending on some config
variables.

In this case, the init_copy_notes_for_rewrite() function calls
git_config() with the notes_rewrite_config() callback function.
This callback, while processing the "notes.rewriteref" variable,
in turn calls string_list_add_refs_by_glob() to process the
associated ref value. This eventually leads to a call to the
get_ref_dir() function, which in turn calls stat(). On cygwin,
the stat() macro leads to an indirect call to cygwin_stat_stub()
which, via init_stat(), then calls git_config() in order to
determine which l/stat implementation to bind to.

In order to solve this problem, we modify git_config() so that the
global state variables used by the config reading code is packaged
up and managed on a local state stack.

06eb708f33 config: always parse GIT_CONFIG_PARAMETERS during git_config
Previously we parsed GIT_CONFIG_PARAMETERS lazily into a
linked list, and then checked that list during future
invocations of git_config. However, that ignores the fact
that the environment variable could change during our run
(e.g., because we parse more "-c" as part of an alias).

Instead, let's just re-parse the environment variable each
time. It's generally not very big, and it's no more work
than parsing the config files, anyway.

As a bonus, we can ditch all of the linked list storage code
entirely, making the code much simpler.

The test unfortunately still does not pass because of an
unrelated bug in handle_options.

ec70f52f6f convert: rename the "eol" global variable to "core_eol"
Yes, it is clear that "eol" wants to mean some sort of end-of-line thing,
but as the name of a global variable, it is way too short to describe what
kind of end-of-line thing it wants to represent. Besides, there are many
codepaths that want to use their own local "char *eol" variable to point
at the end of the current line they are processing.

This global variable holds what we read from core.eol configuration
variable. Name it as such.

e96c19c50f config: support values longer than 1023 bytes
parse_value in config.c has a static buffer of 1024 bytes that it
parse the value into. This can sometimes be a problem when a
config file contains very long values.

It's particularly amusing that git-config already is able to write
such files, so it should probably be able to read them as well.

Fix this by using a strbuf instead of a fixed-size buffer.

9cba13ca5d standardize brace placement in struct definitions
In a struct definitions, unlike functions, the prevailing style is for
the opening brace to go on the same line as the struct name, like so:

 struct foo {
	int bar;
	char *baz;
 };

Indeed, grepping for 'struct [a-z_]* {$' yields about 5 times as many
matches as 'struct [a-z_]*$'.

dce9648916 Make the default abbrev length configurable
The default of 7 comes from fairly early in git development, when
seven hex digits was a lot (it covers about 250+ million hash
values). Back then I thought that 65k revisions was a lot (it was what
we were about to hit in BK), and each revision tends to be about 5-10
new objects or so, so a million objects was a big number.

These days, the kernel isn't even the largest git project, and even
the kernel has about 220k revisions (_much_ bigger than the BK tree
ever was) and we are approaching two million objects. At that point,
seven hex digits is still unique for a lot of them, but when we're
talking about just two orders of magnitude difference between number
of objects and the hash size, there _will_ be collisions in truncated
hash values. It's no longer even close to unrealistic - it happens all
the time.

We should both increase the default abbrev that was unrealistically
small, _and_ add a way for people to set their own default per-project
in the git config file.

This is the first step to first make it configurable; the default of 7
is not raised yet.

This breaks a test in t1300 which used invalid section-less keys in the tests
for "git -c". However, allowing such names there was useless, since there was
no way to set them via config file, and no part of git actually tried to use
section-less keys. This patch updates the test to use more realistic examples
as well as adding its own test.

53c403116a push.default: Rename 'tracking' to 'upstream'
Users are sometimes confused with two different types of "tracking" behavior
in Git: "remote-tracking" branches (e.g. refs/remotes/*/*) versus the
merge/rebase relationship between a local branch and its @{upstream}
(controlled by branch.foo.remote and branch.foo.merge config settings).

When the push.default is set to 'tracking', it specifies that a branch should
be pushed to its @{upstream} branch. In other words, setting push.default to
'tracking' applies only to the latter of the above two types of "tracking"
behavior.

In order to make this more understandable to the user, we rename the
push.default == 'tracking' option to push.default == 'upstream'.

push.default == 'tracking' is left as a deprecated synonym for 'upstream'.

db6195efab handle arbitrary ints in git_config_maybe_bool
This function recently gained the ability to recognize the documented "0"
and "1" values as false/true. However, unlike regular git_config_bool, it
did not treat arbitrary non-zero numbers as true.

While this is undocumented and probably ridiculous for somebody to rely
on, it is safer to behave exactly as git_config_bool would. Because
git_config_maybe_bool can be used to retrofit new non-bool values onto
existing bool options, not behaving in exactly the same way is technically
a regression.

b2be2f6aea log.decorate: accept 0/1 bool values
We explicitly document "0" and "1" as synonyms for "false"
and "true" in boolean config options. However, we don't
actually handle those values in git_config_maybe_bool.

In most cases this works fine, as we call git_config_bool,
which in turn calls git_config_bool_or_int, which in turn
calls git_config_maybe_bool. Values of 0/1 are considered
"not bool", but their integer values end up being converted
to the corresponding boolean values.

However, the log.decorate code looks for maybe_bool
explicitly, so that it can fall back to the "short" and
"full" strings. It does not handle 0/1 at all, and considers
them invalid values.

We cannot simply add 0/1 support to git_config_maybe_bool.
That would confuse git_config_bool_or_int, which may want to
distinguish the integer values "0" and "1" from bools.

The git_config() function signals error by returning -1 in
two instances:

  1. An actual error occurs in opening a config file (parse
     errors cause an immediate die).

  2. Of the three possible config files, none was found.

However, this second case is often not an error at all; it
simply means that the user has no configuration (they are
outside a repo, and they have no ~/.gitconfig file). This
can lead to confusing errors, such as when the bash
completion calls "git config --list" outside of a repo. If
the user has a ~/.gitconfig, the command completes
succesfully; if they do not, it complains to stderr.

This patch allows callers of git_config to distinguish
between the two cases. Error is signaled by -1, and
otherwise the return value is the number of files parsed.
This means that the traditional "git_config(...) < 0" check
for error should work, but callers who want to know whether
we parsed any files or not can still do so.
