config: add conditional include
Sometimes a set of repositories want to share configuration settings
among themselves that are distinct from other such sets of repositories.
A user may work on two projects, each of which have multiple
repositories, and use one user.email for one project while using another
for the other.
Setting $GIT_DIR/.config works, but if the penalty of forgetting to
update $GIT_DIR/.config is high (especially when you end up cloning
often), it may not be the best way to go. Having the settings in
~/.gitconfig, which would work for just one set of repositories, would
not well in such a situation. Having separate ${HOME}s may add more
problems than it solves.
Extend the include.path mechanism that lets a config file include
another config file, so that the inclusion can be done only when some
conditions hold. Then ~/.gitconfig can say "include config-project-A
only when working on project-A" for each project A the user works on.
In this patch, the only supported grouping is based on $GIT_DIR (in
absolute path), so you would need to group repositories by directory, or
something like that to take advantage of it.
We already have include.path for unconditional includes. This patch goes
with includeIf.<condition>.path to make it clearer that a condition is
required. The new config has the same backward compatibility approach as
include.path: older git versions that don't understand includeIf will
simply ignore them.

i18n: config: unfold error messages marked for translation
Introduced in 473166b ("config: add 'origin_type' to config_source
struct", 2016-02-19), Git can inform the user about the origin of a
config error, but the implementation does not allow translators to
translate the keywords 'file', 'blob, 'standard input', and
'submodule-blob'. Moreover, for the second message, a reason for the
error is appended to the message, not allowing translators to translate
that reason either.
Unfold the message into several templates for each known origin_type.
That would result in better translation at the expense of code
verbosity.
Add enum config_oringin_type to ease management of the various
configuration origin types (blob, file, etc). Previously origin type
was considered from command line if cf->origin_type == NULL, i.e.,
uninitialized. Now we set origin_type to CONFIG_ORIGIN_CMDLINE in
git_config_from_parameters() and configset_add_value().
For error message in git_parse_source(), use xstrfmt() function to
prepare the message string, instead of doing something like it's done
for die_bad_number(), because intelligibility and code conciseness are
improved for that instance.

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.

config: add a notion of "scope"
A config callback passed to git_config() doesn't know very
much about the context in which it sees a variable. It can
ask whether the variable comes from a file, and get the file
name. But without analyzing the filename (which is hard to
do accurately), it cannot tell whether it is in system-level
config, user-level config, or repo-specific config.
Generally this doesn't matter; the point of not passing this
to the callback is that it should treat the config the same
no matter where it comes from. But some programs, like
upload-pack, are a special case: we should be able to run
them in an untrusted repository, which means we cannot use
any "dangerous" config from the repository config file (but
it is OK to use it from system or user config).
This patch teaches the config code to record the "scope" of
each variable, and make it available inside config
callbacks, similar to how we give access to the filename.
The scope is the starting source for a particular parsing
operation, and remains the same even if we include other
files (so a .git/config which includes another file will
remain CONFIG_SCOPE_REPO, as it would be similarly
untrusted).

Custom compression levels for objects and packs
Add config variables pack.compression and core.loosecompression ,
and switch --compression=level to pack-objects.
Loose objects will be compressed using core.loosecompression if set,
else core.compression if set, else Z_BEST_SPEED.
Packed objects will be compressed using --compression=level if seen,
else pack.compression if set, else core.compression if set,
else Z_DEFAULT_COMPRESSION. This is the "pack compression level".
Loose objects added to a pack undeltified will be recompressed
to the pack compression level if it is unequal to the current
loose compression level by the preceding rules, or if the loose
object was written while core.legacyheaders = true. Newly
deltified loose objects are always compressed to the current
pack compression level.
Previously packed objects added to a pack are recompressed
to the current pack compression level exactly when their
deltification status changes, since the previous pack data
cannot be reused.
In either case, the --no-reuse-object switch from the first
patch below will always force recompression to the current pack
compression level, instead of assuming the pack compression level
hasn't changed and pack data can be reused when possible.
This applies on top of the following patches from Nicolas Pitre:
[PATCH] allow for undeltified objects not to be reused
[PATCH] make "repack -f" imply "pack-objects --no-reuse-object"

config_buf_ungetc: warn when pushing back a random character
Our config code simulates a stdio stream around a buffer,
but our fake ungetc() does not behave quite like the real
one. In particular, we only rewind the position by one
character, but do _not_ actually put the character from the
caller into position.
It turns out that this does not matter, because we only ever
push back the character we just read. In other words, such
an assignment would be a noop. But because the function is
called ungetc, and because it takes a character parameter,
it is a mistake waiting to happen.
Actually assigning the character into the buffer would be
ideal, but our pointer is actually a "const" copy of the
buffer. We do not know who the real owner of the buffer is
in this code, and would not want to munge their contents.
Instead, we can simply add an assertion that matches what
the current caller does, and will let us know if new callers
are added that violate the contract.

config: add include directive
It can be useful to split your ~/.gitconfig across multiple
files. For example, you might have a "main" file which is
used on many machines, but a small set of per-machine
tweaks. Or you may want to make some of your config public
(e.g., clever aliases) while keeping other data back (e.g.,
your name or other identifying information). Or you may want
to include a number of config options in some subset of your
repos without copying and pasting (e.g., you want to
reference them from the .git/config of participating repos).
This patch introduces an include directive for config files.
It looks like:
[include]
path = /path/to/file
This is syntactically backwards-compatible with existing git
config parsers (i.e., they will see it as another config
entry and ignore it unless you are looking up include.path).
The implementation provides a "git_config_include" callback
which wraps regular config callbacks. Callers can pass it to
git_config_from_file, and it will transparently follow any
include directives, passing all of the discovered options to
the real callback.
Include directives are turned on automatically for "regular"
git config parsing. This includes calls to git_config, as
well as calls to the "git config" program that do not
specify a single file (e.g., using "-f", "--global", etc).
They are not turned on in other cases, including:
1. Parsing of other config-like files, like .gitmodules.
There isn't a real need, and I'd rather be conservative
and avoid unnecessary incompatibility or confusion.
2. Reading single files via "git config". This is for two
reasons:
a. backwards compatibility with scripts looking at
config-like files.
b. inspection of a specific file probably means you
care about just what's in that file, not a general
lookup for "do we have this value anywhere at
all". If that is not the case, the caller can
always specify "--includes".
3. Writing files via "git config"; we want to treat
include.* variables as literal items to be copied (or
modified), and not expand them. So "git config
--unset-all foo.bar" would operate _only_ on
.git/config, not any of its included files (just as it
also does not operate on ~/.gitconfig).

config: allow inaccessible configuration under $HOME
The changes v1.7.12.1~2^2~4 (config: warn on inaccessible files,
2012-08-21) and v1.8.1.1~22^2~2 (config: treat user and xdg config
permission problems as errors, 2012-10-13) were intended to prevent
important configuration (think "[transfer] fsckobjects") from being
ignored when the configuration is unintentionally unreadable (for
example with EIO on a flaky filesystem, or with ENOMEM due to a DoS
attack). Usually ~/.gitconfig and ~/.config/git are readable by the
current user, and if they aren't then it would be easy to fix those
permissions, so the damage from adding this check should have been
minimal.
Unfortunately the access() check often trips when git is being run as
a server. A daemon (such as inetd or git-daemon) starts as "root",
creates a listening socket, and then drops privileges, meaning that
when git commands are invoked they cannot access $HOME and die with
fatal: unable to access '/root/.config/git/config': Permission denied
Any patch to fix this would have one of three problems:
1. We annoy sysadmins who need to take an extra step to handle HOME
when dropping privileges (the current behavior, or any other
proposal that they have to opt into).
2. We annoy sysadmins who want to set HOME when dropping privileges,
either by making what they want to do impossible, or making them
set an extra variable or option to accomplish what used to work
(e.g., a patch to git-daemon to set HOME when --user is passed).
3. We loosen the check, so some cases which might be noteworthy are
not caught.
This patch is of type (3).
Treat user and xdg configuration that are inaccessible due to
permissions (EACCES) as though no user configuration was provided at
all.
An alternative method would be to check if $HOME is readable, but that
would not help in cases where the user who dropped privileges had a
globally readable HOME with only .config or .gitconfig being private.
This does not change the behavior when /etc/gitconfig or .git/config
is unreadable (since those are more serious configuration errors),
nor when ~/.gitconfig or ~/.config/git is unreadable due to problems
other than permissions.

config: add include directive
It can be useful to split your ~/.gitconfig across multiple
files. For example, you might have a "main" file which is
used on many machines, but a small set of per-machine
tweaks. Or you may want to make some of your config public
(e.g., clever aliases) while keeping other data back (e.g.,
your name or other identifying information). Or you may want
to include a number of config options in some subset of your
repos without copying and pasting (e.g., you want to
reference them from the .git/config of participating repos).
This patch introduces an include directive for config files.
It looks like:
[include]
path = /path/to/file
This is syntactically backwards-compatible with existing git
config parsers (i.e., they will see it as another config
entry and ignore it unless you are looking up include.path).
The implementation provides a "git_config_include" callback
which wraps regular config callbacks. Callers can pass it to
git_config_from_file, and it will transparently follow any
include directives, passing all of the discovered options to
the real callback.
Include directives are turned on automatically for "regular"
git config parsing. This includes calls to git_config, as
well as calls to the "git config" program that do not
specify a single file (e.g., using "-f", "--global", etc).
They are not turned on in other cases, including:
1. Parsing of other config-like files, like .gitmodules.
There isn't a real need, and I'd rather be conservative
and avoid unnecessary incompatibility or confusion.
2. Reading single files via "git config". This is for two
reasons:
a. backwards compatibility with scripts looking at
config-like files.
b. inspection of a specific file probably means you
care about just what's in that file, not a general
lookup for "do we have this value anywhere at
all". If that is not the case, the caller can
always specify "--includes".
3. Writing files via "git config"; we want to treat
include.* variables as literal items to be copied (or
modified), and not expand them. So "git config
--unset-all foo.bar" would operate _only_ on
.git/config, not any of its included files (just as it
also does not operate on ~/.gitconfig).

config: add conditional include
Sometimes a set of repositories want to share configuration settings
among themselves that are distinct from other such sets of repositories.
A user may work on two projects, each of which have multiple
repositories, and use one user.email for one project while using another
for the other.
Setting $GIT_DIR/.config works, but if the penalty of forgetting to
update $GIT_DIR/.config is high (especially when you end up cloning
often), it may not be the best way to go. Having the settings in
~/.gitconfig, which would work for just one set of repositories, would
not well in such a situation. Having separate ${HOME}s may add more
problems than it solves.
Extend the include.path mechanism that lets a config file include
another config file, so that the inclusion can be done only when some
conditions hold. Then ~/.gitconfig can say "include config-project-A
only when working on project-A" for each project A the user works on.
In this patch, the only supported grouping is based on $GIT_DIR (in
absolute path), so you would need to group repositories by directory, or
something like that to take advantage of it.
We already have include.path for unconditional includes. This patch goes
with includeIf.<condition>.path to make it clearer that a condition is
required. The new config has the same backward compatibility approach as
include.path: older git versions that don't understand includeIf will
simply ignore them.

config: add include directive
It can be useful to split your ~/.gitconfig across multiple
files. For example, you might have a "main" file which is
used on many machines, but a small set of per-machine
tweaks. Or you may want to make some of your config public
(e.g., clever aliases) while keeping other data back (e.g.,
your name or other identifying information). Or you may want
to include a number of config options in some subset of your
repos without copying and pasting (e.g., you want to
reference them from the .git/config of participating repos).
This patch introduces an include directive for config files.
It looks like:
[include]
path = /path/to/file
This is syntactically backwards-compatible with existing git
config parsers (i.e., they will see it as another config
entry and ignore it unless you are looking up include.path).
The implementation provides a "git_config_include" callback
which wraps regular config callbacks. Callers can pass it to
git_config_from_file, and it will transparently follow any
include directives, passing all of the discovered options to
the real callback.
Include directives are turned on automatically for "regular"
git config parsing. This includes calls to git_config, as
well as calls to the "git config" program that do not
specify a single file (e.g., using "-f", "--global", etc).
They are not turned on in other cases, including:
1. Parsing of other config-like files, like .gitmodules.
There isn't a real need, and I'd rather be conservative
and avoid unnecessary incompatibility or confusion.
2. Reading single files via "git config". This is for two
reasons:
a. backwards compatibility with scripts looking at
config-like files.
b. inspection of a specific file probably means you
care about just what's in that file, not a general
lookup for "do we have this value anywhere at
all". If that is not the case, the caller can
always specify "--includes".
3. Writing files via "git config"; we want to treat
include.* variables as literal items to be copied (or
modified), and not expand them. So "git config
--unset-all foo.bar" would operate _only_ on
.git/config, not any of its included files (just as it
also does not operate on ~/.gitconfig).

git_config_push_parameter: handle empty GIT_CONFIG_PARAMETERS
The "git -c var=value" option stuffs the config value into
$GIT_CONFIG_PARAMETERS, so that sub-processes can see it.
When the config is later read via git_config() or similar,
we parse it back out of that variable. The parsing end is a
little bit picky; it assumes that each entry was generated
with sq_quote_buf(), and that there is no extraneous
whitespace.
On the generating end, we are careful to append to an
existing $GIT_CONFIG_PARAMETERS variable if it exists.
However, our test for "should we add a space separator" is
too liberal: it will add one even if the environment
variable exists but is empty. As a result, you might end up
with:
GIT_CONFIG_PARAMETERS=" 'core.foo=bar'"
which the parser will choke on.
This was hard to trigger in older versions of git, since we
only set the variable when we had something to put into it
(though you could certainly trigger it manually). But since
14111fc (git: submodule honor -c credential.* from command
line, 2016-02-29), the submodule code will unconditionally
put the $GIT_CONFIG_PARAMETERS variable into the environment
of any operation in the submodule, whether it is empty or
not. So any of those operations which themselves use "git
-c" will generate the unparseable value and fail.
We can easily fix it by catching this case on the generating
side. While we're adding a test, let's also check that
multiple layers of "git -c" work, which was previously not
tested at all.

i18n: config: unfold error messages marked for translation
Introduced in 473166b ("config: add 'origin_type' to config_source
struct", 2016-02-19), Git can inform the user about the origin of a
config error, but the implementation does not allow translators to
translate the keywords 'file', 'blob, 'standard input', and
'submodule-blob'. Moreover, for the second message, a reason for the
error is appended to the message, not allowing translators to translate
that reason either.
Unfold the message into several templates for each known origin_type.
That would result in better translation at the expense of code
verbosity.
Add enum config_oringin_type to ease management of the various
configuration origin types (blob, file, etc). Previously origin type
was considered from command line if cf->origin_type == NULL, i.e.,
uninitialized. Now we set origin_type to CONFIG_ORIGIN_CMDLINE in
git_config_from_parameters() and configset_add_value().
For error message in git_parse_source(), use xstrfmt() function to
prepare the message string, instead of doing something like it's done
for die_bad_number(), because intelligibility and code conciseness are
improved for that instance.

config: do not ungetc EOF
When we are parsing a config value, if we see a carriage
return, we fgetc the next character to see if it is a
line feed (in which case we silently drop the CR). If it
isn't, we then ungetc the character, and take the literal
CR.
But we never check whether we in fact got a character at
all. If the config file ends in CR, we will get EOF here,
and try to ungetc EOF. This works OK for a real stdio
stream. The ungetc returns an error, and the next fgetc will
then return EOF again.
However, our custom buffer-based stream is not so fortunate.
It happily rewinds the position of the stream by one
character, ignoring the fact that we fed it EOF. The next
fgetc call returns the final CR again, over and over, and we
end up in an infinite loop.

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.

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.

i18n: config: unfold error messages marked for translation
Introduced in 473166b ("config: add 'origin_type' to config_source
struct", 2016-02-19), Git can inform the user about the origin of a
config error, but the implementation does not allow translators to
translate the keywords 'file', 'blob, 'standard input', and
'submodule-blob'. Moreover, for the second message, a reason for the
error is appended to the message, not allowing translators to translate
that reason either.
Unfold the message into several templates for each known origin_type.
That would result in better translation at the expense of code
verbosity.
Add enum config_oringin_type to ease management of the various
configuration origin types (blob, file, etc). Previously origin type
was considered from command line if cf->origin_type == NULL, i.e.,
uninitialized. Now we set origin_type to CONFIG_ORIGIN_CMDLINE in
git_config_from_parameters() and configset_add_value().
For error message in git_parse_source(), use xstrfmt() function to
prepare the message string, instead of doing something like it's done
for die_bad_number(), because intelligibility and code conciseness are
improved for that instance.

i18n: config: unfold error messages marked for translation
Introduced in 473166b ("config: add 'origin_type' to config_source
struct", 2016-02-19), Git can inform the user about the origin of a
config error, but the implementation does not allow translators to
translate the keywords 'file', 'blob, 'standard input', and
'submodule-blob'. Moreover, for the second message, a reason for the
error is appended to the message, not allowing translators to translate
that reason either.
Unfold the message into several templates for each known origin_type.
That would result in better translation at the expense of code
verbosity.
Add enum config_oringin_type to ease management of the various
configuration origin types (blob, file, etc). Previously origin type
was considered from command line if cf->origin_type == NULL, i.e.,
uninitialized. Now we set origin_type to CONFIG_ORIGIN_CMDLINE in
git_config_from_parameters() and configset_add_value().
For error message in git_parse_source(), use xstrfmt() function to
prepare the message string, instead of doing something like it's done
for die_bad_number(), because intelligibility and code conciseness are
improved for that instance.

Support sizes >=2G in various config options accepting 'g' sizes.
The config options core.packedGitWindowSize, core.packedGitLimit,
core.deltaBaseCacheLimit, core.bigFileThreshold, pack.windowMemory and
pack.packSizeLimit all claim to support suffixes up to and including
'g'. This implies that they should accept sizes >=2G on 64-bit
systems: certainly, specifying a size of 3g should not silently be
translated to zero or transformed into a large negative value due to
integer overflow. However, due to use of git_config_int() rather than
git_config_ulong(), that is exactly what happens:
% git config core.bigFileThreshold 2g
% git gc --aggressive # with extra debugging code to print out
# core.bigfilethreshold after parsing
bigfilethreshold: -2147483648
[...]
This is probably irrelevant for core.deltaBaseCacheLimit, but is
problematic for the other values. (It is particularly problematic for
core.packedGitLimit, which can't even be set to its default value in
the config file due to this bug.)
This fixes things for 32-bit platforms as well. They get the usual bad
config error if an overlarge value is specified, e.g.:
fatal: bad config value for 'core.bigfilethreshold' in /home/nix/.gitconfig
This is detected in all cases, even if the 32-bit platform has no size
larger than 'long'. For signed integral configuration values, we also
detect the case where the value is too large for the signed type but
not the unsigned type.

larger than 'long'. For signed integral configuration values, we also
detect the case where the value is too large for the signed type but
not the unsigned type.

Support sizes >=2G in various config options accepting 'g' sizes.
The config options core.packedGitWindowSize, core.packedGitLimit,
core.deltaBaseCacheLimit, core.bigFileThreshold, pack.windowMemory and
pack.packSizeLimit all claim to support suffixes up to and including
'g'. This implies that they should accept sizes >=2G on 64-bit
systems: certainly, specifying a size of 3g should not silently be
translated to zero or transformed into a large negative value due to
integer overflow. However, due to use of git_config_int() rather than
git_config_ulong(), that is exactly what happens:
% git config core.bigFileThreshold 2g
% git gc --aggressive # with extra debugging code to print out
# core.bigfilethreshold after parsing
bigfilethreshold: -2147483648
[...]
This is probably irrelevant for core.deltaBaseCacheLimit, but is
problematic for the other values. (It is particularly problematic for
core.packedGitLimit, which can't even be set to its default value in
the config file due to this bug.)
This fixes things for 32-bit platforms as well. They get the usual bad
config error if an overlarge value is specified, e.g.:
fatal: bad config value for 'core.bigfilethreshold' in /home/nix/.gitconfig
This is detected in all cases, even if the 32-bit platform has no size
larger than 'long'. For signed integral configuration values, we also
detect the case where the value is too large for the signed type but

git-config: always treat --int as 64-bit internally
When you run "git config --int", the maximum size of integer
you get depends on how git was compiled, and what it
considers to be an "int".
This is almost useful, because your scripts calling "git
config" will behave similarly to git internally. But relying
on this is dubious; you have to actually know how git treats
each value internally (e.g., int versus unsigned long),
which is not documented and is subject to change. And even
if you know it is "unsigned long", we do not have a
git-config option to match that behavior.
Furthermore, you may simply be asking git to store a value
on your behalf (e.g., configuration for a hook). In that
case, the relevant range check has nothing at all to do with
git, but rather with whatever scripting tools you are using
(and git has no way of knowing what the appropriate range is
there).
Not only is the range check useless, but it is actively
harmful, as there is no way at all for scripts to look
at config variables with large values. For instance, one
cannot reliably get the value of pack.packSizeLimit via
git-config. On an LP64 system, git happily uses a 64-bit
"unsigned long" internally to represent the value, but the
script cannot read any value over 2G.
Ideally, the "--int" option would simply represent an
arbitrarily large integer. For practical purposes, however,
a 64-bit integer is large enough, and is much easier to
implement (and if somebody overflows it, we will still
notice the problem, and not simply return garbage).

i18n: config: unfold error messages marked for translation
Introduced in 473166b ("config: add 'origin_type' to config_source
struct", 2016-02-19), Git can inform the user about the origin of a
config error, but the implementation does not allow translators to
translate the keywords 'file', 'blob, 'standard input', and
'submodule-blob'. Moreover, for the second message, a reason for the
error is appended to the message, not allowing translators to translate
that reason either.
Unfold the message into several templates for each known origin_type.
That would result in better translation at the expense of code
verbosity.
Add enum config_oringin_type to ease management of the various
configuration origin types (blob, file, etc). Previously origin type
was considered from command line if cf->origin_type == NULL, i.e.,
uninitialized. Now we set origin_type to CONFIG_ORIGIN_CMDLINE in
git_config_from_parameters() and configset_add_value().
For error message in git_parse_source(), use xstrfmt() function to
prepare the message string, instead of doing something like it's done
for die_bad_number(), because intelligibility and code conciseness are
improved for that instance.

git-config: always treat --int as 64-bit internally
When you run "git config --int", the maximum size of integer
you get depends on how git was compiled, and what it
considers to be an "int".
This is almost useful, because your scripts calling "git
config" will behave similarly to git internally. But relying
on this is dubious; you have to actually know how git treats
each value internally (e.g., int versus unsigned long),
which is not documented and is subject to change. And even
if you know it is "unsigned long", we do not have a
git-config option to match that behavior.
Furthermore, you may simply be asking git to store a value
on your behalf (e.g., configuration for a hook). In that
case, the relevant range check has nothing at all to do with
git, but rather with whatever scripting tools you are using
(and git has no way of knowing what the appropriate range is
there).
Not only is the range check useless, but it is actively
harmful, as there is no way at all for scripts to look
at config variables with large values. For instance, one
cannot reliably get the value of pack.packSizeLimit via
git-config. On an LP64 system, git happily uses a 64-bit
"unsigned long" internally to represent the value, but the
script cannot read any value over 2G.
Ideally, the "--int" option would simply represent an
arbitrarily large integer. For practical purposes, however,
a 64-bit integer is large enough, and is much easier to
implement (and if somebody overflows it, we will still
notice the problem, and not simply return garbage).

else pack.compression if set, else core.compression if set,
else Z_DEFAULT_COMPRESSION. This is the "pack compression level".
Loose objects added to a pack undeltified will be recompressed
to the pack compression level if it is unequal to the current
loose compression level by the preceding rules, or if the loose
object was written while core.legacyheaders = true. Newly
deltified loose objects are always compressed to the current
pack compression level.
Previously packed objects added to a pack are recompressed
to the current pack compression level exactly when their
deltification status changes, since the previous pack data
cannot be reused.
In either case, the --no-reuse-object switch from the first
patch below will always force recompression to the current pack
compression level, instead of assuming the pack compression level
hasn't changed and pack data can be reused when possible.
This applies on top of the following patches from Nicolas Pitre:
[PATCH] allow for undeltified objects not to be reused
[PATCH] make "repack -f" imply "pack-objects --no-reuse-object"

This is detected in all cases, even if the 32-bit platform has no size

Lazy man's auto-CRLF
It currently does NOT know about file attributes, so it does its
conversion purely based on content. Maybe that is more in the "git
philosophy" anyway, since content is king, but I think we should try to do
the file attributes to turn it off on demand.
Anyway, BY DEFAULT it is off regardless, because it requires a
[core]
AutoCRLF = true
in your config file to be enabled. We could make that the default for
Windows, of course, the same way we do some other things (filemode etc).
But you can actually enable it on UNIX, and it will cause:
- "git update-index" will write blobs without CRLF
- "git diff" will diff working tree files without CRLF
- "git checkout" will write files to the working tree _with_ CRLF
and things work fine.
Funnily, it actually shows an odd file in git itself:
git clone -n git test-crlf
cd test-crlf
git config core.autocrlf true
git checkout
git diff
shows a diff for "Documentation/docbook-xsl.css". Why? Because we have
actually checked in that file *with* CRLF! So when "core.autocrlf" is
true, we'll always generate a *different* hash for it in the index,
because the index hash will be for the content _without_ CRLF.
Is this complete? I dunno. It seems to work for me. It doesn't use the
filename at all right now, and that's probably a deficiency (we could
certainly make the "is_binary()" heuristics also take standard filename
heuristics into account).
I don't pass in the filename at all for the "index_fd()" case
(git-update-index), so that would need to be passed around, but this
actually works fine.
NOTE NOTE NOTE! The "is_binary()" heuristics are totally made-up by yours
truly. I will not guarantee that they work at all reasonable. Caveat
emptor. But it _is_ simple, and it _is_ safe, since it's all off by
default.
The patch is pretty simple - the biggest part is the new "convert.c" file,
but even that is really just basic stuff that anybody can write in
"Teaching C 101" as a final project for their first class in programming.
Not to say that it's bug-free, of course - but at least we're not talking
about rocket surgery here.

safecrlf: Add mechanism to warn about irreversible crlf conversions
CRLF conversion bears a slight chance of corrupting data.
autocrlf=true will convert CRLF to LF during commit and LF to
CRLF during checkout. A file that contains a mixture of LF and
CRLF before the commit cannot be recreated by git. For text
files this is the right thing to do: it corrects line endings
such that we have only LF line endings in the repository.
But for binary files that are accidentally classified as text the
conversion can corrupt data.
If you recognize such corruption early you can easily fix it by
setting the conversion type explicitly in .gitattributes. Right
after committing you still have the original file in your work
tree and this file is not yet corrupted. You can explicitly tell
git that this file is binary and git will handle the file
appropriately.
Unfortunately, the desired effect of cleaning up text files with
mixed line endings and the undesired effect of corrupting binary
files cannot be distinguished. In both cases CRLFs are removed
in an irreversible way. For text files this is the right thing
to do because CRLFs are line endings, while for binary files
converting CRLFs corrupts data.
This patch adds a mechanism that can either warn the user about
an irreversible conversion or can even refuse to convert. The
mechanism is controlled by the variable core.safecrlf, with the
following values:
- false: disable safecrlf mechanism
- warn: warn about irreversible conversions
- true: refuse irreversible conversions
The default is to warn. Users are only affected by this default
if core.autocrlf is set. But the current default of git is to
leave core.autocrlf unset, so users will not see warnings unless
they deliberately chose to activate the autocrlf mechanism.
The safecrlf mechanism's details depend on the git command. The
general principles when safecrlf is active (not false) are:
- we warn/error out if files in the work tree can modified in an
irreversible way without giving the user a chance to backup the
original file.
- for read-only operations that do not modify files in the work tree
we do not not print annoying warnings.
There are exceptions. Even though...
- "git add" itself does not touch the files in the work tree, the
next checkout would, so the safety triggers;
- "git apply" to update a text file with a patch does touch the files
in the work tree, but the operation is about text files and CRLF
conversion is about fixing the line ending inconsistencies, so the
safety does not trigger;
- "git diff" itself does not touch the files in the work tree, it is
often run to inspect the changes you intend to next "git add". To
catch potential problems early, safety triggers.
The concept of a safety check was originally proposed in a similar
way by Linus Torvalds. Thanks to Dimitry Potapov for insisting
on getting the naked LF/autocrlf=true case right.

next checkout would, so the safety triggers;
- "git apply" to update a text file with a patch does touch the files
in the work tree, but the operation is about text files and CRLF
conversion is about fixing the line ending inconsistencies, so the
safety does not trigger;
- "git diff" itself does not touch the files in the work tree, it is
often run to inspect the changes you intend to next "git add". To
catch potential problems early, safety triggers.
The concept of a safety check was originally proposed in a similar
way by Linus Torvalds. Thanks to Dimitry Potapov for insisting
on getting the naked LF/autocrlf=true case right.

git on Mac OS and precomposed unicode
Mac OS X mangles file names containing unicode on file systems HFS+,
VFAT or SAMBA. When a file using unicode code points outside ASCII
is created on a HFS+ drive, the file name is converted into
decomposed unicode and written to disk. No conversion is done if
the file name is already decomposed unicode.
Calling open("\xc3\x84", ...) with a precomposed "Ä" yields the same
result as open("\x41\xcc\x88",...) with a decomposed "Ä".
As a consequence, readdir() returns the file names in decomposed
unicode, even if the user expects precomposed unicode. Unlike on
HFS+, Mac OS X stores files on a VFAT drive (e.g. an USB drive) in
precomposed unicode, but readdir() still returns file names in
decomposed unicode. When a git repository is stored on a network
share using SAMBA, file names are send over the wire and written to
disk on the remote system in precomposed unicode, but Mac OS X
readdir() returns decomposed unicode to be compatible with its
behaviour on HFS+ and VFAT.
The unicode decomposition causes many problems:
- The names "git add" and other commands get from the end user may
often be precomposed form (the decomposed form is not easily input
from the keyboard), but when the commands read from the filesystem
to see what it is going to update the index with already is on the
filesystem, readdir() will give decomposed form, which is different.
- Similarly "git log", "git mv" and all other commands that need to
compare pathnames found on the command line (often but not always
precomposed form; a command line input resulting from globbing may
be in decomposed) with pathnames found in the tree objects (should
be precomposed form to be compatible with other systems and for
consistency in general).
- The same for names stored in the index, which should be
precomposed, that may need to be compared with the names read from
readdir().
NFS mounted from Linux is fully transparent and does not suffer from
the above.
As Mac OS X treats precomposed and decomposed file names as equal,
we can
- wrap readdir() on Mac OS X to return the precomposed form, and
- normalize decomposed form given from the command line also to the
precomposed form,
to ensure that all pathnames used in Git are always in the
precomposed form. This behaviour can be requested by setting
"core.precomposedunicode" configuration variable to true.
The code in compat/precomposed_utf8.c implements basically 4 new
functions: precomposed_utf8_opendir(), precomposed_utf8_readdir(),
precomposed_utf8_closedir() and precompose_argv(). The first three
are to wrap opendir(3), readdir(3), and closedir(3) functions.
The argv[] conversion allows to use the TAB filename completion done
by the shell on command line. It tolerates other tools which use
readdir() to feed decomposed file names into git.
When creating a new git repository with "git init" or "git clone",
"core.precomposedunicode" will be set "false".
The user needs to activate this feature manually. She typically
sets core.precomposedunicode to "true" on HFS and VFAT, or file
systems mounted via SAMBA.

mingw: introduce the 'core.hideDotFiles' setting
On Unix (and Linux), files and directories whose names start with a dot
are usually not shown by default. This convention is used by Git: the
.git/ directory should be left alone by regular users, and only accessed
through Git itself.
On Windows, no such convention exists. Instead, there is an explicit flag
to mark files or directories as hidden.
In the early days, Git for Windows did not mark the .git/ directory (or
for that matter, any file or directory whose name starts with a dot)
hidden. This lead to quite a bit of confusion, and even loss of data.
Consequently, Git for Windows introduced the core.hideDotFiles setting,
with three possible values: true, false, and dotGitOnly, defaulting to
marking only the .git/ directory as hidden.
The rationale: users do not need to access .git/ directly, and indeed (as
was demonstrated) should not really see that directory, either. However,
not all dot files should be hidden by default, as e.g. Eclipse does not
show them (and the user would therefore be unable to see, say, a
.gitattributes file).
In over five years since the last attempt to bring this patch into core
Git, a slightly buggy version of this patch has served Git for Windows'
users well: no single report indicated problems with the hidden .git/
directory, and the stream of problems caused by the previously non-hidden
.git/ directory simply stopped. The bugs have been fixed during the
process of getting this patch upstream.
Note that there is a funny quirk we have to pay attention to when
creating hidden files: we use Win32's _wopen() function which
transmogrifies its arguments and hands off to Win32's CreateFile()
function. That latter function errors out with ERROR_ACCESS_DENIED (the
equivalent of EACCES) when the equivalent of the O_CREAT flag was passed
and the file attributes (including the hidden flag) do not match an
existing file's. And _wopen() accepts no parameter that would be
transmogrified into said hidden flag. Therefore, we simply try again
without O_CREAT.
A slightly different method is required for our fopen()/freopen()
function as we cannot even *remove* the implicit O_CREAT flag.
Therefore, we briefly mark existing files as unhidden when opening them
via fopen()/freopen().
The ERROR_ACCESS_DENIED error can also be triggered by opening a file
that is marked as a system file (which is unlikely to be tracked in
Git), and by trying to create a file that has *just* been deleted and is
awaiting the last open handles to be released (which would be handled
better by the "Try again?" logic, a story for a different patch series,
though). In both cases, it does not matter much if we try again without
the O_CREAT flag, read: it does not hurt, either.
For details how ERROR_ACCESS_DENIED can be triggered, see
https://msdn.microsoft.com/en-us/library/windows/desktop/aa363858

core.excludesfile clean-up
There are inconsistencies in the way commands currently handle
the core.excludesfile configuration variable. The problem is
the variable is too new to be noticed by anything other than
git-add and git-status.
* git-ls-files does not notice any of the "ignore" files by
default, as it predates the standardized set of ignore files.
The calling scripts established the convention to use
.git/info/exclude, .gitignore, and later core.excludesfile.
* git-add and git-status know about it because they call
add_excludes_from_file() directly with their own notion of
which standard set of ignore files to use. This is just a
stupid duplication of code that need to be updated every time
the definition of the standard set of ignore files is
changed.
* git-read-tree takes --exclude-per-directory=<gitignore>,
not because the flexibility was needed. Again, this was
because the option predates the standardization of the ignore
files.
* git-merge-recursive uses hardcoded per-directory .gitignore
and nothing else. git-clean (scripted version) does not
honor core.* because its call to underlying ls-files does not
know about it. git-clean in C (parked in 'pu') doesn't either.
We probably could change git-ls-files to use the standard set
when no excludes are specified on the command line and ignore
processing was asked, or something like that, but that will be a
change in semantics and might break people's scripts in a subtle
way. I am somewhat reluctant to make such a change.
On the other hand, I think it makes perfect sense to fix
git-read-tree, git-merge-recursive and git-clean to follow the
same rule as other commands. I do not think of a valid use case
to give an exclude-per-directory that is nonstandard to
read-tree command, outside a "negative" test in the t1004 test
script.
This patch is the first step to untangle this mess.
The next step would be to teach read-tree, merge-recursive and
clean (in C) to use setup_standard_excludes().

i18n: config: unfold error messages marked for translation
Introduced in 473166b ("config: add 'origin_type' to config_source
struct", 2016-02-19), Git can inform the user about the origin of a
config error, but the implementation does not allow translators to
translate the keywords 'file', 'blob, 'standard input', and
'submodule-blob'. Moreover, for the second message, a reason for the
error is appended to the message, not allowing translators to translate
that reason either.
Unfold the message into several templates for each known origin_type.
That would result in better translation at the expense of code
verbosity.
Add enum config_oringin_type to ease management of the various
configuration origin types (blob, file, etc). Previously origin type
was considered from command line if cf->origin_type == NULL, i.e.,
uninitialized. Now we set origin_type to CONFIG_ORIGIN_CMDLINE in
git_config_from_parameters() and configset_add_value().
For error message in git_parse_source(), use xstrfmt() function to
prepare the message string, instead of doing something like it's done
for die_bad_number(), because intelligibility and code conciseness are
improved for that instance.

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.

sha1_file: convert read_sha1_file to struct object_id
Convert read_sha1_file to take a pointer to struct object_id and rename
it read_object_file. Do the same for read_sha1_file_extended.
Convert one use in grep.c to use the new function without any other code
change, since the pointer being passed is a void pointer that is already
initialized with a pointer to struct object_id. Update the declaration
and definitions of the modified functions, and apply the following
semantic patch to convert the remaining callers:

Read configuration also from $HOME/.gitconfig
This patch is based on Pasky's, with three notable differences:
- I did not yet update the documentation
- I named it .gitconfig, not .gitrc
- git-repo-config does not barf when a unique key is overridden locally
The last means that if you have something like
[alias]
l = log --stat -M
in ~/.gitconfig, and
[alias]
l = log --stat -M next..
in $GIT_DIR/config, then
git-repo-config alias.l
returns only one value, namely the value from $GIT_DIR/config.
If you set the environment variable GIT_CONFIG, $HOME/.gitconfig is not
read, and neither $GIT_DIR/config, but $GIT_CONFIG instead.
If you set GIT_CONFIG_LOCAL instead, it is interpreted instead of
$GIT_DIR/config, but $HOME/.gitconfig is still read.

config: add a notion of "scope"
A config callback passed to git_config() doesn't know very
much about the context in which it sees a variable. It can
ask whether the variable comes from a file, and get the file
name. But without analyzing the filename (which is hard to
do accurately), it cannot tell whether it is in system-level
config, user-level config, or repo-specific config.
Generally this doesn't matter; the point of not passing this
to the callback is that it should treat the config the same
no matter where it comes from. But some programs, like
upload-pack, are a special case: we should be able to run
them in an untrusted repository, which means we cannot use
any "dangerous" config from the repository config file (but
it is OK to use it from system or user config).
This patch teaches the config code to record the "scope" of
each variable, and make it available inside config
callbacks, similar to how we give access to the filename.
The scope is the starting source for a particular parsing
operation, and remains the same even if we include other
files (so a .git/config which includes another file will
remain CONFIG_SCOPE_REPO, as it would be similarly
untrusted).

config: add include directive
It can be useful to split your ~/.gitconfig across multiple
files. For example, you might have a "main" file which is
used on many machines, but a small set of per-machine
tweaks. Or you may want to make some of your config public
(e.g., clever aliases) while keeping other data back (e.g.,
your name or other identifying information). Or you may want
to include a number of config options in some subset of your
repos without copying and pasting (e.g., you want to
reference them from the .git/config of participating repos).
This patch introduces an include directive for config files.
It looks like:
[include]
path = /path/to/file
This is syntactically backwards-compatible with existing git
config parsers (i.e., they will see it as another config
entry and ignore it unless you are looking up include.path).
The implementation provides a "git_config_include" callback
which wraps regular config callbacks. Callers can pass it to
git_config_from_file, and it will transparently follow any
include directives, passing all of the discovered options to
the real callback.
Include directives are turned on automatically for "regular"
git config parsing. This includes calls to git_config, as
well as calls to the "git config" program that do not
specify a single file (e.g., using "-f", "--global", etc).
They are not turned on in other cases, including:
1. Parsing of other config-like files, like .gitmodules.
There isn't a real need, and I'd rather be conservative
and avoid unnecessary incompatibility or confusion.
2. Reading single files via "git config". This is for two
reasons:
a. backwards compatibility with scripts looking at
config-like files.
b. inspection of a specific file probably means you
care about just what's in that file, not a general
lookup for "do we have this value anywhere at
all". If that is not the case, the caller can
always specify "--includes".
3. Writing files via "git config"; we want to treat
include.* variables as literal items to be copied (or
modified), and not expand them. So "git config
--unset-all foo.bar" would operate _only_ on
.git/config, not any of its included files (just as it
also does not operate on ~/.gitconfig).

config: add include directive
It can be useful to split your ~/.gitconfig across multiple
files. For example, you might have a "main" file which is
used on many machines, but a small set of per-machine
tweaks. Or you may want to make some of your config public
(e.g., clever aliases) while keeping other data back (e.g.,
your name or other identifying information). Or you may want
to include a number of config options in some subset of your
repos without copying and pasting (e.g., you want to
reference them from the .git/config of participating repos).
This patch introduces an include directive for config files.
It looks like:
[include]
path = /path/to/file
This is syntactically backwards-compatible with existing git
config parsers (i.e., they will see it as another config
entry and ignore it unless you are looking up include.path).
The implementation provides a "git_config_include" callback

config: provide a version of git_config with more options
Callers may want to provide a specific version of a file in which to look
for config. Right now this can be done by setting the magic global
config_exclusive_filename variable. By providing a version of git_config
that takes a filename, we can take a step towards making this magic global
go away.
Furthermore, by providing a more "advanced" interface, we now have a a
natural place to add new options for callers like git-config, which care
about tweaking the specifics of config lookup, without disturbing the
large number of "simple" users (i.e., every other part of git).
The astute reader of this patch may notice that the logic for handling
config_exclusive_filename was taken out of git_config_early, but added
into git_config. This means that git_config_early will no longer respect
config_exclusive_filename. That's OK, because the only other caller of
git_config_early is check_repository_format_gently, but the only function
which sets config_exclusive_filename is cmd_config, which does not call
check_repository_format_gently (and if it did, it would have been a bug,
anyway, as we would be checking the repository format in the wrong file).

i18n: config: unfold error messages marked for translation
Introduced in 473166b ("config: add 'origin_type' to config_source
struct", 2016-02-19), Git can inform the user about the origin of a
config error, but the implementation does not allow translators to
translate the keywords 'file', 'blob, 'standard input', and
'submodule-blob'. Moreover, for the second message, a reason for the
error is appended to the message, not allowing translators to translate
that reason either.
Unfold the message into several templates for each known origin_type.
That would result in better translation at the expense of code
verbosity.
Add enum config_oringin_type to ease management of the various
configuration origin types (blob, file, etc). Previously origin type
was considered from command line if cf->origin_type == NULL, i.e.,
uninitialized. Now we set origin_type to CONFIG_ORIGIN_CMDLINE in
git_config_from_parameters() and configset_add_value().
For error message in git_parse_source(), use xstrfmt() function to
prepare the message string, instead of doing something like it's done
for die_bad_number(), because intelligibility and code conciseness are
improved for that instance.

config: add a notion of "scope"
A config callback passed to git_config() doesn't know very
much about the context in which it sees a variable. It can
ask whether the variable comes from a file, and get the file
name. But without analyzing the filename (which is hard to
do accurately), it cannot tell whether it is in system-level
config, user-level config, or repo-specific config.
Generally this doesn't matter; the point of not passing this
to the callback is that it should treat the config the same
no matter where it comes from. But some programs, like
upload-pack, are a special case: we should be able to run
them in an untrusted repository, which means we cannot use
any "dangerous" config from the repository config file (but
it is OK to use it from system or user config).
This patch teaches the config code to record the "scope" of
each variable, and make it available inside config
callbacks, similar to how we give access to the filename.
The scope is the starting source for a particular parsing
operation, and remains the same even if we include other
files (so a .git/config which includes another file will
remain CONFIG_SCOPE_REPO, as it would be similarly
untrusted).

config: add core.untrackedCache
When we know that mtime on directory as given by the environment
is usable for the purpose of untracked cache, we may want the
untracked cache to be always used without any mtime test or
kernel name check being performed.
Also when we know that mtime is not usable for the purpose of
untracked cache, for example because the repo is shared over a
network file system, we may want the untracked-cache to be
automatically removed from the index.
Allow the user to express such preference by setting the
'core.untrackedCache' configuration variable, which can take
'keep', 'false', or 'true' and default to 'keep'.
When read_index_from() is called, it now adds or removes the
untracked cache in the index to respect the value of this
variable. So it does nothing if the value is `keep` or if the
variable is unset; it adds the untracked cache if the value is
`true`; and it removes the cache if the value is `false`.
`git update-index --[no-|force-]untracked-cache` still adds the
untracked cache to, or removes it, from the index, but this
shows a warning if it goes against the value of
core.untrackedCache, because the next time the index is read
the untracked cache will be added or removed if the
configuration is set to do so.
Also `--untracked-cache` used to check that the underlying
operating system and file system change `st_mtime` field of a
directory if files are added or deleted in that directory. But
because those tests take a long time, `--untracked-cache` no
longer performs them. Instead, there is now
`--test-untracked-cache` to perform the tests. This change
makes `--untracked-cache` the same as `--force-untracked-cache`.
This last change is backward incompatible and should be
mentioned in the release notes.

git_config_set: make use of the config parser's event stream
In the recent commit with the title "config: introduce an optional event
stream while parsing", we introduced an optional callback to keep track
of the config parser's events "comment", "white-space", "section header"
and "entry".
One motivation for this feature was to make use of it in the code that
edits the config. And this commit makes it so.
Note: this patch changes the meaning of the `seen` array that records
whether we saw the config entry that is to be edited: previously, it
contained the end offset of the found entry. Now, we introduce a new
array `parsed` that keeps a record of *all* config parser events (with
begin/end offsets), and the items in the `seen` array now point into the
`parsed` array.
There are two reasons why we do it this way:
1. To keep the implementation simple, the config parser's event stream
reports the event only after the config callback was called, so we
would not receive the begin offset otherwise.
2. In the following patches, we will re-use the `parsed` array to fix two
long-standing bugs related to empty sections.
Note that this also makes the code more robust with respect to finding the
begin offset of the part(s) of the config file to be edited, as we no
longer back-track to find the beginning of the line.

git config --unset: remove empty sections (in the common case)
The original reasoning for not removing section headers upon removal of
the last entry went like this: the user could have added comments about
the section, or about the entries therein, and if there were other
comments there, we would not know whether we should remove them.
In particular, a concocted example was presented that looked like this
(and was added to t1300):
# some generic comment on the configuration file itself
# a comment specific to this "section" section.
[section]
# some intervening lines
# that should also be dropped
key = value
# please be careful when you update the above variable
The ideal thing for `git config --unset section.key` in this case would
be to leave only the first line behind, because all the other comments
are now obsolete.
However, this is unfeasible, short of adding a complete Natural Language
Processing module to Git, which seems not only a lot of work, but a
totally unreasonable feature (for little benefit to most users).
Now, the real kicker about this problem is: most users do not edit their
config files at all! In their use case, the config looks like this
instead:
[section]
key = value
... and it is totally obvious what should happen if the entry is
removed: the entire section should vanish.
Let's generalize this observation to this conservative strategy: if we
are removing the last entry from a section, and there are no comments
inside that section nor surrounding it, then remove the entire section.
Otherwise behave as before: leave the now-empty section (including those
comments, even ones about the now-deleted entry).
We have to be extra careful to handle the case where more than one entry
is removed: any subset of them might be the last entries of their
respective sections (and if there are no comments in or around that
section, the section should be removed, too).

git_config_set: make use of the config parser's event stream
In the recent commit with the title "config: introduce an optional event
stream while parsing", we introduced an optional callback to keep track
of the config parser's events "comment", "white-space", "section header"
and "entry".
One motivation for this feature was to make use of it in the code that
edits the config. And this commit makes it so.
Note: this patch changes the meaning of the `seen` array that records
whether we saw the config entry that is to be edited: previously, it
contained the end offset of the found entry. Now, we introduce a new
array `parsed` that keeps a record of *all* config parser events (with
begin/end offsets), and the items in the `seen` array now point into the
`parsed` array.
There are two reasons why we do it this way:
1. To keep the implementation simple, the config parser's event stream
reports the event only after the config callback was called, so we
would not receive the begin offset otherwise.
2. In the following patches, we will re-use the `parsed` array to fix two
long-standing bugs related to empty sections.
Note that this also makes the code more robust with respect to finding the
begin offset of the part(s) of the config file to be edited, as we no
longer back-track to find the beginning of the line.

git_config_set: make use of the config parser's event stream
In the recent commit with the title "config: introduce an optional event
stream while parsing", we introduced an optional callback to keep track
of the config parser's events "comment", "white-space", "section header"
and "entry".
One motivation for this feature was to make use of it in the code that
edits the config. And this commit makes it so.
Note: this patch changes the meaning of the `seen` array that records
whether we saw the config entry that is to be edited: previously, it
contained the end offset of the found entry. Now, we introduce a new
array `parsed` that keeps a record of *all* config parser events (with
begin/end offsets), and the items in the `seen` array now point into the
`parsed` array.
There are two reasons why we do it this way:
1. To keep the implementation simple, the config parser's event stream
reports the event only after the config callback was called, so we
would not receive the begin offset otherwise.
2. In the following patches, we will re-use the `parsed` array to fix two
long-standing bugs related to empty sections.
Note that this also makes the code more robust with respect to finding the
begin offset of the part(s) of the config file to be edited, as we no
longer back-track to find the beginning of the line.

consistently use "fallthrough" comments in switches
Gcc 7 adds -Wimplicit-fallthrough, which can warn when a
switch case falls through to the next case. The general idea
is that the compiler can't tell if this was intentional or
not, so you should annotate any intentional fall-throughs as
such, leaving it to complain about any unannotated ones.
There's a GNU __attribute__ which can be used for
annotation, but of course we'd have to #ifdef it away on
non-gcc compilers. Gcc will also recognize
specially-formatted comments, which matches our current
practice. Let's extend that practice to all of the
unannotated sites (which I did look over and verify that
they were behaving as intended).
Ideally in each case we'd actually give some reasons in the
comment about why we're falling through, or what we're
falling through to. And gcc does support that with
-Wimplicit-fallthrough=2, which relaxes the comment pattern
matching to anything that contains "fallthrough" (or a
variety of spelling variants). However, this isn't the
default for -Wimplicit-fallthrough, nor for -Wextra. In the
name of simplicity, it's probably better for us to support
the default level, which requires "fallthrough" to be the
only thing in the comment (modulo some window dressing like
"else" and some punctuation; see the gcc manual for the
complete set of patterns).
This patch suppresses all warnings due to
-Wimplicit-fallthrough. We might eventually want to add that
to the DEVELOPER Makefile knob, but we should probably wait
until gcc 7 is more widely adopted (since earlier versions
will complain about the unknown warning type).

git config --unset: remove empty sections (in the common case)
The original reasoning for not removing section headers upon removal of
the last entry went like this: the user could have added comments about
the section, or about the entries therein, and if there were other
comments there, we would not know whether we should remove them.
In particular, a concocted example was presented that looked like this
(and was added to t1300):
# some generic comment on the configuration file itself
# a comment specific to this "section" section.
[section]
# some intervening lines
# that should also be dropped
key = value
# please be careful when you update the above variable
The ideal thing for `git config --unset section.key` in this case would
be to leave only the first line behind, because all the other comments
are now obsolete.
However, this is unfeasible, short of adding a complete Natural Language
Processing module to Git, which seems not only a lot of work, but a
totally unreasonable feature (for little benefit to most users).
Now, the real kicker about this problem is: most users do not edit their
config files at all! In their use case, the config looks like this
instead:
[section]
key = value
... and it is totally obvious what should happen if the entry is
removed: the entire section should vanish.
Let's generalize this observation to this conservative strategy: if we
are removing the last entry from a section, and there are no comments
inside that section nor surrounding it, then remove the entire section.
Otherwise behave as before: leave the now-empty section (including those
comments, even ones about the now-deleted entry).
We have to be extra careful to handle the case where more than one entry
is removed: any subset of them might be the last entries of their
respective sections (and if there are no comments in or around that
section, the section should be removed, too).

git config --unset: remove empty sections (in the common case)
The original reasoning for not removing section headers upon removal of
the last entry went like this: the user could have added comments about
the section, or about the entries therein, and if there were other
comments there, we would not know whether we should remove them.
In particular, a concocted example was presented that looked like this
(and was added to t1300):
# some generic comment on the configuration file itself
# a comment specific to this "section" section.
[section]
# some intervening lines
# that should also be dropped
key = value
# please be careful when you update the above variable
The ideal thing for `git config --unset section.key` in this case would
be to leave only the first line behind, because all the other comments
are now obsolete.
However, this is unfeasible, short of adding a complete Natural Language
Processing module to Git, which seems not only a lot of work, but a
totally unreasonable feature (for little benefit to most users).
Now, the real kicker about this problem is: most users do not edit their
config files at all! In their use case, the config looks like this
instead:
[section]
key = value
... and it is totally obvious what should happen if the entry is
removed: the entire section should vanish.
Let's generalize this observation to this conservative strategy: if we
are removing the last entry from a section, and there are no comments
inside that section nor surrounding it, then remove the entire section.
Otherwise behave as before: leave the now-empty section (including those
comments, even ones about the now-deleted entry).
We have to be extra careful to handle the case where more than one entry
is removed: any subset of them might be the last entries of their
respective sections (and if there are no comments in or around that
section, the section should be removed, too).

git_config_set: make use of the config parser's event stream
In the recent commit with the title "config: introduce an optional event
stream while parsing", we introduced an optional callback to keep track
of the config parser's events "comment", "white-space", "section header"
and "entry".
One motivation for this feature was to make use of it in the code that
edits the config. And this commit makes it so.
Note: this patch changes the meaning of the `seen` array that records
whether we saw the config entry that is to be edited: previously, it
contained the end offset of the found entry. Now, we introduce a new
array `parsed` that keeps a record of *all* config parser events (with
begin/end offsets), and the items in the `seen` array now point into the
`parsed` array.
There are two reasons why we do it this way:
1. To keep the implementation simple, the config parser's event stream
reports the event only after the config callback was called, so we
would not receive the begin offset otherwise.
2. In the following patches, we will re-use the `parsed` array to fix two
long-standing bugs related to empty sections.
Note that this also makes the code more robust with respect to finding the
begin offset of the part(s) of the config file to be edited, as we no
longer back-track to find the beginning of the line.

git config --unset: remove empty sections (in the common case)
The original reasoning for not removing section headers upon removal of
the last entry went like this: the user could have added comments about
the section, or about the entries therein, and if there were other
comments there, we would not know whether we should remove them.
In particular, a concocted example was presented that looked like this
(and was added to t1300):
# some generic comment on the configuration file itself
# a comment specific to this "section" section.
[section]
# some intervening lines
# that should also be dropped
key = value
# please be careful when you update the above variable
The ideal thing for `git config --unset section.key` in this case would
be to leave only the first line behind, because all the other comments
are now obsolete.
However, this is unfeasible, short of adding a complete Natural Language
Processing module to Git, which seems not only a lot of work, but a
totally unreasonable feature (for little benefit to most users).
Now, the real kicker about this problem is: most users do not edit their
config files at all! In their use case, the config looks like this
instead:
[section]
key = value
... and it is totally obvious what should happen if the entry is
removed: the entire section should vanish.
Let's generalize this observation to this conservative strategy: if we
are removing the last entry from a section, and there are no comments
inside that section nor surrounding it, then remove the entire section.
Otherwise behave as before: leave the now-empty section (including those
comments, even ones about the now-deleted entry).
We have to be extra careful to handle the case where more than one entry
is removed: any subset of them might be the last entries of their
respective sections (and if there are no comments in or around that
section, the section should be removed, too).

config: avoid "write_in_full(fd, buf, len) < len" pattern
The return type of write_in_full() is a signed ssize_t,
because we may return "-1" on failure (even if we succeeded
in writing some bytes). But "len" itself is may be an
unsigned type (the function takes a size_t, but of course we
may have something else in the calling function). So while
it seems like:
if (write_in_full(fd, buf, len) < len)
die_errno("write error");
would trigger on error, it won't if "len" is unsigned. The
compiler sees a signed/unsigned comparison and promotes the
signed value, resulting in (size_t)-1, the highest possible
size_t (or again, whatever type the caller has). This cannot
possibly be smaller than "len", and so the conditional can
never trigger.
I scoured the code base for cases of this, but it turns out
that these two in git_config_set_multivar_in_file_gently()
are the only ones. Here our "len" is the difference between
two size_t variables, making the result an unsigned size_t.
We can fix this by just checking for a negative return value
directly, as write_in_full() will never return any value
except -1 or the full count.
There's no addition to the test suite here, since you need
to convince write() to fail in order to see the problem. The
simplest reproduction recipe I came up with is to trigger
ENOSPC:
# make a limited-size filesystem
dd if=/dev/zero of=small.disk bs=1M count=1
mke2fs small.disk
mkdir mnt
sudo mount -o loop small.disk mnt
cd mnt
sudo chown $USER:$USER .
# make a config file with some content
git config --file=config one.key value
git config --file=config two.key value
# now fill up the disk
dd if=/dev/zero of=fill

# of the file to config.lock, and will fail on write()
git config --file=config --unset two.key
That final command should (and does after this patch)
produce an error message due to the failed write, and leave
the file intact. Instead, it silently ignores the failure
and renames config.lock into place, leaving you with a
totally empty config file!

avoid "write_in_full(fd, buf, len) != len" pattern
The return value of write_in_full() is either "-1", or the
requested number of bytes[1]. If we make a partial write
before seeing an error, we still return -1, not a partial
value. This goes back to f6aa66cb95 (write_in_full: really
write in full or return error on disk full., 2007-01-11).
So checking anything except "was the return value negative"
is pointless. And there are a couple of reasons not to do
so:
1. It can do a funny signed/unsigned comparison. If your
"len" is signed (e.g., a size_t) then the compiler will
promote the "-1" to its unsigned variant.
This works out for "!= len" (unless you really were
trying to write the maximum size_t bytes), but is a
bug if you check "< len" (an example of which was fixed
recently in config.c).
We should avoid promoting the mental model that you
need to check the length at all, so that new sites are
not tempted to copy us.
2. Checking for a negative value is shorter to type,
especially when the length is an expression.
3. Linus says so. In d34cf19b89 (Clean up write_in_full()
users, 2007-01-11), right after the write_in_full()
semantics were changed, he wrote:
I really wish every "write_in_full()" user would just
check against "<0" now, but this fixes the nasty and
stupid ones.
Appeals to authority aside, this makes it clear that
writing it this way does not have an intentional
benefit. It's a historical curiosity that we never
bothered to clean up (and which was undoubtedly
cargo-culted into new sites).
So let's convert these obviously-correct cases (this
includes write_str_in_full(), which is just a wrapper for
write_in_full()).
[1] A careful reader may notice there is one way that
write_in_full() can return a different value. If we ask
write() to write N bytes and get a return value that is
_larger_ than N, we could return a larger total. But
besides the fact that this would imply a totally broken
version of write(), it would already invoke undefined
behavior. Our internal remaining counter is an unsigned
size_t, which means that subtracting too many byte will
wrap it around to a very large number. So we'll instantly
begin reading off the end of the buffer, trying to write
gigabytes (or petabytes) of data.

git_config_set: make use of the config parser's event stream
In the recent commit with the title "config: introduce an optional event
stream while parsing", we introduced an optional callback to keep track
of the config parser's events "comment", "white-space", "section header"
and "entry".
One motivation for this feature was to make use of it in the code that
edits the config. And this commit makes it so.
Note: this patch changes the meaning of the `seen` array that records
whether we saw the config entry that is to be edited: previously, it
contained the end offset of the found entry. Now, we introduce a new
array `parsed` that keeps a record of *all* config parser events (with
begin/end offsets), and the items in the `seen` array now point into the
`parsed` array.
There are two reasons why we do it this way:
1. To keep the implementation simple, the config parser's event stream
reports the event only after the config callback was called, so we
would not receive the begin offset otherwise.
2. In the following patches, we will re-use the `parsed` array to fix two
long-standing bugs related to empty sections.
Note that this also makes the code more robust with respect to finding the
begin offset of the part(s) of the config file to be edited, as we no
longer back-track to find the beginning of the line.

config: avoid "write_in_full(fd, buf, len) < len" pattern
The return type of write_in_full() is a signed ssize_t,
because we may return "-1" on failure (even if we succeeded
in writing some bytes). But "len" itself is may be an
unsigned type (the function takes a size_t, but of course we
may have something else in the calling function). So while
it seems like:
if (write_in_full(fd, buf, len) < len)
die_errno("write error");
would trigger on error, it won't if "len" is unsigned. The
compiler sees a signed/unsigned comparison and promotes the
signed value, resulting in (size_t)-1, the highest possible
size_t (or again, whatever type the caller has). This cannot
possibly be smaller than "len", and so the conditional can
never trigger.
I scoured the code base for cases of this, but it turns out
that these two in git_config_set_multivar_in_file_gently()
are the only ones. Here our "len" is the difference between
two size_t variables, making the result an unsigned size_t.
We can fix this by just checking for a negative return value
directly, as write_in_full() will never return any value
except -1 or the full count.
There's no addition to the test suite here, since you need
to convince write() to fail in order to see the problem. The
simplest reproduction recipe I came up with is to trigger
ENOSPC:
# make a limited-size filesystem
dd if=/dev/zero of=small.disk bs=1M count=1
mke2fs small.disk
mkdir mnt
sudo mount -o loop small.disk mnt
cd mnt
sudo chown $USER:$USER .
# make a config file with some content
git config --file=config one.key value
git config --file=config two.key value
# now fill up the disk
dd if=/dev/zero of=fill
# and try to delete a key, which requires copying the rest
# of the file to config.lock, and will fail on write()
git config --file=config --unset two.key
That final command should (and does after this patch)
produce an error message due to the failed write, and leave
the file intact. Instead, it silently ignores the failure
and renames config.lock into place, leaving you with a
totally empty config file!

branch: add a --copy (-c) option to go with --move (-m)
Add the ability to --copy a branch and its reflog and configuration,
this uses the same underlying machinery as the --move (-m) option
except the reflog and configuration is copied instead of being moved.
This is useful for e.g. copying a topic branch to a new version,
e.g. work to work-2 after submitting the work topic to the list, while
preserving all the tracking info and other configuration that goes
with the branch, and unlike --move keeping the other already-submitted
branch around for reference.
Like --move, when the source branch is the currently checked out
branch the HEAD is moved to the destination branch. In the case of
--move we don't really have a choice (other than remaining on a
detached HEAD) and in order to keep the functionality consistent, we
are doing it in similar way for --copy too.
The most common usage of this feature is expected to be moving to a
new topic branch which is a copy of the current one, in that case
moving to the target branch is what the user wants, and doesn't
unexpectedly behave differently than --move would.
One outstanding caveat of this implementation is that:
git checkout maint &&
git checkout master &&
git branch -c topic &&
git checkout -
Will check out 'maint' instead of 'master'. This is because the @{-N}
feature (or its -1 shorthand "-") relies on HEAD reflogs created by
the checkout command, so in this case we'll checkout maint instead of
master, as the user might expect. What to do about that is left to a
future change.

branch: add a --copy (-c) option to go with --move (-m)
Add the ability to --copy a branch and its reflog and configuration,
this uses the same underlying machinery as the --move (-m) option
except the reflog and configuration is copied instead of being moved.
This is useful for e.g. copying a topic branch to a new version,
e.g. work to work-2 after submitting the work topic to the list, while
preserving all the tracking info and other configuration that goes
with the branch, and unlike --move keeping the other already-submitted
branch around for reference.
Like --move, when the source branch is the currently checked out
branch the HEAD is moved to the destination branch. In the case of
--move we don't really have a choice (other than remaining on a
detached HEAD) and in order to keep the functionality consistent, we
are doing it in similar way for --copy too.
The most common usage of this feature is expected to be moving to a
new topic branch which is a copy of the current one, in that case
moving to the target branch is what the user wants, and doesn't
unexpectedly behave differently than --move would.
One outstanding caveat of this implementation is that:
git checkout maint &&
git checkout master &&
git branch -c topic &&
git checkout -
Will check out 'maint' instead of 'master'. This is because the @{-N}
feature (or its -1 shorthand "-") relies on HEAD reflogs created by
the checkout command, so in this case we'll checkout maint instead of
master, as the user might expect. What to do about that is left to a
future change.

avoid "write_in_full(fd, buf, len) != len" pattern
The return value of write_in_full() is either "-1", or the
requested number of bytes[1]. If we make a partial write
before seeing an error, we still return -1, not a partial
value. This goes back to f6aa66cb95 (write_in_full: really
write in full or return error on disk full., 2007-01-11).
So checking anything except "was the return value negative"
is pointless. And there are a couple of reasons not to do
so:
1. It can do a funny signed/unsigned comparison. If your
"len" is signed (e.g., a size_t) then the compiler will
promote the "-1" to its unsigned variant.
This works out for "!= len" (unless you really were
trying to write the maximum size_t bytes), but is a
bug if you check "< len" (an example of which was fixed
recently in config.c).
We should avoid promoting the mental model that you
need to check the length at all, so that new sites are
not tempted to copy us.
2. Checking for a negative value is shorter to type,
especially when the length is an expression.
3. Linus says so. In d34cf19b89 (Clean up write_in_full()
users, 2007-01-11), right after the write_in_full()
semantics were changed, he wrote:
I really wish every "write_in_full()" user would just
check against "<0" now, but this fixes the nasty and
stupid ones.
Appeals to authority aside, this makes it clear that
writing it this way does not have an intentional
benefit. It's a historical curiosity that we never
bothered to clean up (and which was undoubtedly
cargo-culted into new sites).
So let's convert these obviously-correct cases (this
includes write_str_in_full(), which is just a wrapper for
write_in_full()).
[1] A careful reader may notice there is one way that
write_in_full() can return a different value. If we ask
write() to write N bytes and get a return value that is
_larger_ than N, we could return a larger total. But
besides the fact that this would imply a totally broken
version of write(), it would already invoke undefined
behavior. Our internal remaining counter is an unsigned
size_t, which means that subtracting too many byte will
wrap it around to a very large number. So we'll instantly
begin reading off the end of the buffer, trying to write
gigabytes (or petabytes) of data.

branch: add a --copy (-c) option to go with --move (-m)
Add the ability to --copy a branch and its reflog and configuration,
this uses the same underlying machinery as the --move (-m) option
except the reflog and configuration is copied instead of being moved.
This is useful for e.g. copying a topic branch to a new version,
e.g. work to work-2 after submitting the work topic to the list, while
preserving all the tracking info and other configuration that goes
with the branch, and unlike --move keeping the other already-submitted
branch around for reference.
Like --move, when the source branch is the currently checked out
branch the HEAD is moved to the destination branch. In the case of
--move we don't really have a choice (other than remaining on a
detached HEAD) and in order to keep the functionality consistent, we
are doing it in similar way for --copy too.
The most common usage of this feature is expected to be moving to a
new topic branch which is a copy of the current one, in that case
moving to the target branch is what the user wants, and doesn't
unexpectedly behave differently than --move would.
One outstanding caveat of this implementation is that:
git checkout maint &&
git checkout master &&
git branch -c topic &&
git checkout -
Will check out 'maint' instead of 'master'. This is because the @{-N}
feature (or its -1 shorthand "-") relies on HEAD reflogs created by
the checkout command, so in this case we'll checkout maint instead of
master, as the user might expect. What to do about that is left to a
future change.

parse_config_key: allow matching single-level config
The parse_config_key() function was introduced to make it
easier to match "section.subsection.key" variables. It also
handles the simpler "section.key", and the caller is
responsible for distinguishing the two from its
out-parameters.
Most callers who _only_ want "section.key" would just use a
strcmp(var, "section.key"), since there is no parsing
required. However, they may still use parse_config_key() if
their "section" variable isn't a constant (an example of
this is in parse_hide_refs_config).
Using the parse_config_key is a bit clunky, though:
const char *subsection;
int subsection_len;
const char *key;
if (!parse_config_key(var, section, &subsection, &subsection_len, &key) &&
!subsection) {
/* matched! */
}
Instead, let's treat a NULL subsection as an indication that
the caller does not expect one. That lets us write:
const char *key;
if (!parse_config_key(var, section, NULL, NULL, &key)) {
/* matched! */
}
Existing callers should be unaffected, as passing a NULL
subsection would currently segfault.

i18n: config: unfold error messages marked for translation
Introduced in 473166b ("config: add 'origin_type' to config_source
struct", 2016-02-19), Git can inform the user about the origin of a
config error, but the implementation does not allow translators to
translate the keywords 'file', 'blob, 'standard input', and
'submodule-blob'. Moreover, for the second message, a reason for the
error is appended to the message, not allowing translators to translate
that reason either.
Unfold the message into several templates for each known origin_type.
That would result in better translation at the expense of code
verbosity.
Add enum config_oringin_type to ease management of the various
configuration origin types (blob, file, etc). Previously origin type
was considered from command line if cf->origin_type == NULL, i.e.,
uninitialized. Now we set origin_type to CONFIG_ORIGIN_CMDLINE in
git_config_from_parameters() and configset_add_value().
For error message in git_parse_source(), use xstrfmt() function to
prepare the message string, instead of doing something like it's done
for die_bad_number(), because intelligibility and code conciseness are
improved for that instance.

error is appended to the message, not allowing translators to translate
that reason either.
Unfold the message into several templates for each known origin_type.
That would result in better translation at the expense of code
verbosity.
Add enum config_oringin_type to ease management of the various
configuration origin types (blob, file, etc). Previously origin type
was considered from command line if cf->origin_type == NULL, i.e.,
uninitialized. Now we set origin_type to CONFIG_ORIGIN_CMDLINE in
git_config_from_parameters() and configset_add_value().
For error message in git_parse_source(), use xstrfmt() function to
prepare the message string, instead of doing something like it's done
for die_bad_number(), because intelligibility and code conciseness are
improved for that instance.

config: add a notion of "scope"
A config callback passed to git_config() doesn't know very
much about the context in which it sees a variable. It can
ask whether the variable comes from a file, and get the file
name. But without analyzing the filename (which is hard to
do accurately), it cannot tell whether it is in system-level
config, user-level config, or repo-specific config.
Generally this doesn't matter; the point of not passing this
to the callback is that it should treat the config the same
no matter where it comes from. But some programs, like
upload-pack, are a special case: we should be able to run
them in an untrusted repository, which means we cannot use
any "dangerous" config from the repository config file (but
it is OK to use it from system or user config).
This patch teaches the config code to record the "scope" of
each variable, and make it available inside config
callbacks, similar to how we give access to the filename.
The scope is the starting source for a particular parsing
operation, and remains the same even if we include other
files (so a .git/config which includes another file will
remain CONFIG_SCOPE_REPO, as it would be similarly
untrusted).
