[PATCH 0/1] config: allow user to know scope of config options

[Matthew Rogers via GitGitGadget]

This was originally a pull request to the git-for-windows repository
[https://github.com/git-for-windows/git/pull/2399]. It adds a new option
--show-scope which would allow a user to see what scope a given
configuration value has (sytem, local, global, etc.).

These are correct changes, but is unrelated noise in the context of
the theme of the patch, no?

The above is slightly tricky; --global/--system/--local are made
mutually exclusive in the higher level, so if any of them is set,
we do not even need to look at the "scope" to tell what kind of
source we are reading from.

I am not sure what the implication of saying "they came from the
command line" when we read from the standard input or from a blob.

In any case, the need for such logic that says "scope might not say
it is REPO, but when use_local_config is true, we are doing a local
config" implies that "scope" parameter the caller of this function
has is not set correctly when these options are used---would that be
the real bug that needs fixing, rather than getting "worked around"
with a code like this?

It almost makes me point fingers at config.c::config_with_options()
where config_source is inspected and git_config_from_*() helpers are
called without setting the current_parsing_scope.  Unlike these
cases, when do_git_config_sequence() is called from that function,
the scope is recorded in the variable before each standard config
source file is opened and read.  What would we be breaking if we
taught the function to set the current_parsing_scope variable
correctly even when reading from the config_source?  That would
certainly simplify this function quite a lot, but if the other parts
of the codebase relies on the current behaviour, we cannot make such
a change lightly.

Isn't this overkill?  I think this code was copied-and-pasted from
the other function that needs to show an arbitrary end-user supplied
data which is a pathname, so it makes perfect sense to use c-style
quoting, but the token scope_to_string() returns is taken from a
bounded set that doesn't require such quoting, no?

Doesn't this also need a man page update as well for adding the option
to the synopsis.

The commit message doesn't fully highlight that the config list will
often be all the users config values, so each value will be
disambiguated/identified as to it's origin.

I think that's the case, would the recommended course of action be to
move these changes into its own commit?

So the way I structured these was to mirror the way other parts 
of this file check if we should be doing a --local, etc. and mirrored 
that here.  This could definitely be cleaned up if we change the behavior
with how --local, etc. set the current_config_scope.

I agree with you here, I only put this as "command line" 
because they came from a place that was ultimately fed in from 
command line options (--file/--blob).  I wouldn't have a problem with 
calling them out as their own scope ("file", "blob", "stdin").

From what I can tell from a cursory glance. the only two clients of 
this function are remote.c and upload-pack.c.  The usecase for remote.c
 mostly seems to be to determine the result of `remote_is_configured()`
which (more importantly) seems to be done when that iterates through 
the relevant configuration options.  Similarly for upload-pack.c.

I don't think it would be harmful for git config --local, etc. to set that
as we would normally intuit.

Yeah, I guess that is a copy+paste mistake.  I don't think its 
necessary since we control the input into this function, So I'll fix 
that.

I'm agreed on these. So I'll look to readjust that.

As the author of the SCOPE enum, I think this is the right direction.
The only users of current_config_scope() are in config callbacks (e.g.,
upload_pack_config() checks it for the "packobjectshook"), which you
couldn't trigger via "git config" anyway.

The main reason I didn't set the scope before in config_with_options()
is that it's not given the scope at all; git-config resolves it to the
filename. So if git_config_source grows an enum to select the type, and
all that filename-resolution gets pushed down into config_with_options(),
the whole thing would fall out naturally, I think.

Yup, and it generally is a good idea to make such a clean-up patch
either early in the series, or as a standalone patch (with a note
under three-dash lines that another topic is coming on top of the
cleanup), because it would be much less likely to introduce new bugs
and can be merged quicly to 'next' and then to 'master' to serve as
a base to build your other changes on top.

I don't really understand what you mean by "it's origin" here.  When
you say origin, do you mean in the "--show-origin" sense of "file/blob/etc."
or something else? Because scope is kind of an orthogonal concept to origin
in that sense as you can have files with different origins but the same scope.

Thanks,
Matt

I do not think origin and scope are orghogonal, though.  Can the
same file appear as the source for different configuration var-value
pair in two different scopes?

It is likely that you can _guess_ with high precision that given a
pathname reported by --show-origin what scope it is in.  It on the
other hand is not so trivial given a scope to guess which exact file
a var-value pair came from, I would think.\

I meant orthogonal in two senses:

That given the current implementation you don't need to have both
options active at
the same time but can have them active at both times.

And that origin and scope correlate, but aren't necessarily
one-for-one.  For example, --show-origin lists in a known order, but it follows
includes and lists the origin as the included file.  so if you include a file
globally which has includeif "gitdir:..." directives then it can get hairy when
all your config files are structured like that.

Although, to be fair I doubt that that kind of situation is normal

Normally yes, but things can get complicating depending on your
configuration/include situation.

Yes, exactly.  When I see "orthogonal", I expect the word describes
things that do not correlate.

I can see values in the option that gives scope but not path in
order to write scripts that limits var-value pairs to be used
(e.g. "I do not want to be affected by the per-repository values",
"I do not trust settings that comes system-wide").  I also can see
values in the option that gives only path when debugging the
configuration file.

I briefly wondered, for the purpose of such "I do want to see only
those settings coming from these scopes" script, it may make more
sense to have the command _filter_ the var-value pairs, instead of
showing all of them with label, but that feature always exists ;-)

[PATCH v2 0/4] config: allow user to know scope of config options

[Matthew Rogers via GitGitGadget]

This was originally a pull request to the git-for-windows repository
[https://github.com/git-for-windows/git/pull/2399]. It adds a new option
--show-scope which would allow a user to see what scope a given
configuration value has (sytem, local, global, etc.).

changes since v1:

 * Cleaned up meaning of scoping, specifically separating "repo" into
   "local" and "worktree" as well as expanding "cmdline" into "command"
   scoping, added submodule scoping
 * Taught struct git_config_source to remember the scope of the command that
   is filling it out
 * do_git_config_sequence() now remembers the previous scope so that if it
   is called recursively it can remember where it was.

     -    config: allow user to know scope of config options
     +    config: add '--show-scope' to print the scope of a config value
      
     -    Add new option --show-scope which allows a user to know what the scope
     -    of listed config options are (local/global/system/etc.).
     +    When a user queries config values with --show-origin, often it's
     +    difficult to determine what the actual "scope" (local, global, etc.) of
     +    a given value is based on just the origin file.
     +
     +    Teach 'git config' the '--show-scope' option to print the scope of all
     +    displayed config values.  Note that we should never see anything of
     +    "submodule" scope as that is only ever used by submodule-config.c when
     +    parsing the '.gitmodules' file.

[PATCH v2 1/4] config: fix typo in variable name

[Matthew Rogers via GitGitGadget]

From: Matthew Rogers <mattr94@gmail.com>

In git config use of the end_null variable to determine if we should be
null terminating our output.  While it is correct to say a string is
"null terminated" the character is actually the "nul" character, so this
malapropism is being fixed.

[PATCH v2 2/4] config: fix config scope enum

[Matthew Rogers via GitGitGadget]

From: Matthew Rogers <mattr94@gmail.com>

Previously when iterating through git config variables, worktree config
and local config were both considered "CONFIG_SCOPE_REPO".  This was
never a problem before as no one had needed to differentiate between the
two cases.

Additionally we rename what was CONFIG_SCOPE_REPO to CONFIG_SCOPE_LOCAL
to reflect its new, more specific meaning.

The clients of 'current_config_scope()' who cared about
CONFIG_SCOPE_REPO are also modified to similarly care about
CONFIG_SCOPE_WORKTREE and CONFIG_SCOPE_LOCAL to preserve previous behavior.

[PATCH v2 3/4] config: clarify meaning of command line scoping

[Matthew Rogers via GitGitGadget]

From: Matthew Rogers <mattr94@gmail.com>

CONFIG_SCOPE_CMDLINE is generally used in the code to refer to config
values passed in via the -c option.  This is a little bit too specific
as there are other methods to pass config values so that the last for a
single command (namely --file and --blob).  As the "visibility" of config
values passed by these situations is common, we unify them as having a
scope of "command" rather than "command line".

[PATCH v2 4/4] config: add '--show-scope' to print the scope of a config value

[Matthew Rogers via GitGitGadget]

From: Matthew Rogers <mattr94@gmail.com>

When a user queries config values with --show-origin, often it's
difficult to determine what the actual "scope" (local, global, etc.) of
a given value is based on just the origin file.

Teach 'git config' the '--show-scope' option to print the scope of all
displayed config values.  Note that we should never see anything of
"submodule" scope as that is only ever used by submodule-config.c when
parsing the '.gitmodules' file.

Hmph, then "fix" on the title is a bit misleading, no?  

The enum may not have been as fine grained as you would have liked,
but if there was nothing broken, then we are doing this not to "fix"
anything.  

A more important thing to explain would probably be why we
(i.e. those who propose this change, those who give favoriable
reviews to it, and those who accept it change to the system) would
want to see finer-grained classification.  What do we expect to be
able to do with the resulting finer-grained set that we wouldn't be
able to with the original, and why is it a good thing?  That is what
readers of the proposed log message of this change would want to
see, I would think.

Obviously correct.

Malapropism is a new word in "git log" output in our history ;-)

Sorry, but I cannot parse this, especially around "so that the last
for ..." part.

Is the "unification" something done by this patch?  It does not
appear to be so.  The existing code already was using CMDLINE to
call "git -c VAR=VAL" and also something else (which is not clear to
me, unfortunately, probably because I failed to parse the above
X-<), and this step renames CMDLINE to COMMAND perhaps because
CMDLINE has too strong connotation with the "-c" thing and much less
with the other thing (which is not clear to me, unfortunately) and
you found that renaming it to COMMAND would cover both cases better?

I also do not get what you meant by "visibility", but it probably is
primarily because it is not clear what "the other thing" is.

Style: the outermost opening and closing parentheses of a functiond

Makes me wonder if this wants to be done via a table, which would
later allow a parser to map in the other direction, taking a string
and returning the corresponding enum, more easily (imagine a yet to
be invented feature to "list config settings for only this scope").

Shouldn't one of these show scope instead of origin?  I wonder how
the tests I see later in the patch could have passed with this.

These that set scope for individual sources, not just during the
normal sequence, are new in this round, and I think it is an
improvement.

I see where you're coming from, but I would definitely consider this a "fix"
in that it's something that (as explained in the deleted comment) should
have been this way from the start but was unnecessary as no one had a
need for it yet.  But I definitely wouldn't be against changing the phrasing
to something like "clean up" or whatever your preferred wording would be.

This is really more prep for patch 4 later on in this series, as a user who
ran the proposed '--show-scope' later on in the series would care what
was "worktree" vs "local".

Regardless, I think the two options I have would be to amend the commit
message with that extra information or roll it together with patch 4

My bad, I guess I must have not read as carefully as I thought I did.
It should read:

for a single command ..."

Essentially, the "unification" was referring to more the unification of all the
things that affect configuration only for the duration of a specific command.

The gist of this patch was to say "There are a few ways besides -c to pass
a configuration option that lasts for a single command, so it makes sense
to broaden that scope.".  The change is definitely justified in that COMMAND
communicates that much clearer than CMDLINE as REPO, GLOBAL, SYSTEM
all describe the thing that can see the configuration options, and
it's specifically the
command the can see the -c options and not the command line as a whole.

I was using visibility as another way to conceptualize scoping.  A
scope more or less determines who can "see" a thing, so maybe that
language was a little bit too much in my head.

The issue is that currently the code doesn't care about any of that (as only -c
options actually have COMMAND scoping), so maybe I should roll it into the
next patch of the series?  As that introduces code that actually cares about the
difference?

I was thinking the same but then I realized such an option already exists,
--local and company.

Oof, that was a blunder... I think this passes the tests because none of them
actually hits `format_config()` only `show_all_config()` so I'll definitely add
a test case for this. (and fix it while I'm at it)

The user-facing option is still spelled "null". Obviously we can't just
change that, but if we are trying to prefer "nul", should we offer both?

I think we actually _do_ allow "--nul" because of parse-option's
willingness to accept a partial name. But if we wanted to advertise one
over the other in "-h", then we'd have to set up the alias ourselves.

Interestingly, "xargs" (and GNU grep) spells it as "--null", so perhaps
that's an argument to keep it as-is. Likewise if we accept that "null
termination" is a correct name, I suppose.

[PATCH v3 0/4] config: allow user to know scope of config options

[Matthew Rogers via GitGitGadget]

This was originally a pull request to the git-for-windows repository
[https://github.com/git-for-windows/git/pull/2399]. It adds a new option
--show-scope which would allow a user to see what scope a given
configuration value has (sytem, local, global, etc.).

changes since v2:

 * Redid commit messages for content/clarity
 * Minor fixes around using --show-scope with a single value (format_config)

[PATCH v3 1/4] config: fix typo in variable name

[Matthew Rogers via GitGitGadget]

From: Matthew Rogers <mattr94@gmail.com>

In git config use of the end_null variable to determine if we should be
null terminating our output.  While it is correct to say a string is
"null terminated" the character is actually the "nul" character, so this
malapropism is being fixed.

[PATCH v3 2/4] config: refine config scope enum

[Matthew Rogers via GitGitGadget]

From: Matthew Rogers <mattr94@gmail.com>

Previously when iterating through git config variables, worktree config
and local config were both considered "CONFIG_SCOPE_REPO".  This was
never a problem before as no one had needed to differentiate between the
two cases, but future functionality may care whether or not the config
options come from a worktree or from the repository's actual local
config file.  For example, the planned feature to add a '--show-scope'
to config to allow a user to see which scope listed config options come
from would confuse users if it just printed 'repo' rather than 'local'
or 'worktree' as the documentation would lead them to expect.  As well
as the additional benefit of making the implementation look more like
how the documentation describes the interface.

To accomplish this we split out what was previously considered repo
scope to be local and worktree.

The clients of 'current_config_scope()' who cared about
CONFIG_SCOPE_REPO are also modified to similarly care about
CONFIG_SCOPE_WORKTREE and CONFIG_SCOPE_LOCAL to preserve previous behavior.

[PATCH v3 3/4] config: clarify meaning of command line scoping

[Matthew Rogers via GitGitGadget]

From: Matthew Rogers <mattr94@gmail.com>

CONFIG_SCOPE_CMDLINE is generally used in the code to refer to config
values passed in via the -c option.  Options passed in using this
mechanism share similar scoping characteristics with the --file and
--blob options of the 'config' command, namely that they are only in use
for that single invocation of git, and that they supersede the normal
system/global/local hierarchy.  This patch introduces
CONFIG_SCOPE_COMMAND to reflect this new idea, which also makes
CONFIG_SCOPE_CMDLINE redundant.

[PATCH v3 4/4] config: add '--show-scope' to print the scope of a config value

[Matthew Rogers via GitGitGadget]

From: Matthew Rogers <mattr94@gmail.com>

When a user queries config values with --show-origin, often it's
difficult to determine what the actual "scope" (local, global, etc.) of
a given value is based on just the origin file.

Teach 'git config' the '--show-scope' option to print the scope of all
displayed config values.  Note that we should never see anything of
"submodule" scope as that is only ever used by submodule-config.c when
parsing the '.gitmodules' file.

So the gist of the change is to split REPO into two, LOCAL and
WORKTREE.

If we can find a way to state that concisely, perhaps we can improve
"refine enum" and make it more informative.

All of the above justifies why it makes sense to treat --file,
--blob and "git -c VAR=VAL" as the same scope (i.e. it would have
been a nice part of log message of the commit that introduced
SCOPE_CMDLINE), but that is not something we need to justify
now---we have such a scope for one-shot settings and these three
sources are already treated as the same class.

The change in this commit is to rename CMDLINE to COMMAND.  That is
what the proposed log message for this step must justify.

	We internally use CONFIG_SCOPE_CMDLINE for the scope for the
	configuration variables that come from "git -c VAR=VAL",
	"git config --file=FILE" and "git config --blob=BLOB".  As
	we are going to expose the scope names to end-users in the
	next step, let's rethink the half-cryptic "cmdline" and
	instead use a proper word "command" (the settings from three
	sources in this scope are all in effect only during a single
	invocation of a git command).

or something like that.

The only externally observable effect of this patch is this output
string from test-tool and we are not breaking end-user experience,
but I am not sure if this churn is worth it.  I dunno.

In any case, the change to t1308 we saw in the previous step belongs
to this step, I think.

It is a shame that with this defined in the main part of the system
test-tool still needs to carry its own private copy.

I wonder if it results in a better system if we rename this to

	const char *config_scope_name(enum config_scope scope)

made it externally visible, and use it in t/helper/test-config.c
and get rid of the private copy scope_name() there?

And this is the logical place to make an external definition, if we

The HERE-DOC is over-indented.  All the body lines should align with
cat and EOF.  The same comment applies to many "<<-" added by this
patch---mimick the "<<-" that appear in earlier part of the same

Missing blank line between two tests.

I wonder if we want to revamp the tests for --show-origin that wants
to make sure a funny filename is quoted properly.  For that purpose,
CUSTOM_CONFIG_FILE is given a funny pathname, and it would have been
OK to use that only for a single "do we quote properly?" test, but
instead we use that same funnily-named file as the source in many
places where we do not *care* how --show-origin quotes the pathname
at all, and end up having to skip with !MINGW.

It's a bad tradition that started at 45bf3297 ("t1300: fix the new
--show-origin tests on Windows", 2016-03-23), I guess, and is not a
new problem introduced by this patch, but it should stop so that we
can have a better test coverage everywhere.

Other than that, I think that the new feature added by this series
is a sensible one.  Thanks for working on it.

+1 and please keep the order in config_scope_name the same as in the
enum definition. Will base my 'remote rename &

I meant to put this change into the next series in the patch, but I
must have messed up, so I'll readjust that.

Re: [PATCH v3 3/4] config: clarify meaning of command line scoping

So this isn't technically correct, as before the final patch of this series we
technically don't set the current_parsing_scope for those options.  This
doesn't actually affect anything though, because before then nothing actually
checks the current_parsing_scope during such calls to git config.  As such,
it makes sense to me to keep that part of the commit message.

I like this explanation much better so I'll roll that into the commit message.

Yeah, this was my bad...

Re: [PATCH v3 4/4] config: add '--show-scope' to print the scope of a config value

I was mimicking the style of the --show-origin tests, and didn't realize this
was a style violation.  This is done in a few tests, so I'll add a patch
that just goes through the file and fixes that for the existing tests as well.

Yeah, I think phrasing along that line would work well.

	config: split repo scope to local and worktree

That's 46 chars.

[PATCH v4 0/6] config: allow user to know scope of config options

[Matthew Rogers via GitGitGadget]

This was originally a pull request to the git-for-windows repository
[https://github.com/git-for-windows/git/pull/2399]. It adds a new option
--show-scope which would allow a user to see what scope a given
configuration value has (sytem, local, global, etc.).

changes since v3:

 * Cleaned up t1300
 * Expanded test coverage for t1300 to not rely as much on !MINGW by using a
   simpler filename for most tests
 * config_scope_name is now exposed in config.h
 * cleaned up commit messages for clarity/content (again)

[PATCH v4 1/6] config: fix typo in variable name

[Matthew Rogers via GitGitGadget]

From: Matthew Rogers <mattr94@gmail.com>

In git config use of the end_null variable to determine if we should be
null terminating our output.  While it is correct to say a string is
"null terminated" the character is actually the "nul" character, so this
malapropism is being fixed.

[PATCH v4 3/6] t1300: create custom config file without special characters

[Matthew Rogers via GitGitGadget]

From: Matthew Rogers <mattr94@gmail.com>

Tests that required a custom configuration file to be created previously
used a file with non-alphanumeric characters including escaped double
quotes.  This is not really necessary for the majority of tests
involving custom config files, and decreases test coverage on systems
that dissallow such filenames (Windows, etc.).

Create two files, one appropriate for testing quoting and one
appropriate for general use.

[PATCH v4 4/6] config: split repo scope to local and worktree

[Matthew Rogers via GitGitGadget]

From: Matthew Rogers <mattr94@gmail.com>

Previously when iterating through git config variables, worktree config
and local config were both considered "CONFIG_SCOPE_REPO".  This was
never a problem before as no one had needed to differentiate between the
two cases, but future functionality may care whether or not the config
options come from a worktree or from the repository's actual local
config file.  For example, the planned feature to add a '--show-scope'
to config to allow a user to see which scope listed config options come
from would confuse users if it just printed 'repo' rather than 'local'
or 'worktree' as the documentation would lead them to expect.  As well
as the additional benefit of making the implementation look more like
how the documentation describes the interface.

To accomplish this we split out what was previously considered repo
scope to be local and worktree.

The clients of 'current_config_scope()' who cared about
CONFIG_SCOPE_REPO are also modified to similarly care about
CONFIG_SCOPE_WORKTREE and CONFIG_SCOPE_LOCAL to preserve previous behavior.

[PATCH v4 5/6] config: clarify meaning of command line scoping

[Matthew Rogers via GitGitGadget]

From: Matthew Rogers <mattr94@gmail.com>

CONFIG_SCOPE_CMDLINE is generally used in the code to refer to config
values passed in via the -c option.  Options passed in using this
mechanism share similar scoping characteristics with the --file and
--blob options of the 'config' command, namely that they are only in use
for that single invocation of git, and that they supersede the normal
system/global/local hierarchy.  This patch introduces
CONFIG_SCOPE_COMMAND to reflect this new idea, which also makes
CONFIG_SCOPE_CMDLINE redundant.

[PATCH v4 6/6] config: add '--show-scope' to print the scope of a config value

[Matthew Rogers via GitGitGadget]

From: Matthew Rogers <mattr94@gmail.com>

When a user queries config values with --show-origin, often it's
difficult to determine what the actual "scope" (local, global, etc.) of
a given value is based on just the origin file.

Teach 'git config' the '--show-scope' option to print the scope of all
displayed config values.  Note that we should never see anything of
"submodule" scope as that is only ever used by submodule-config.c when
parsing the '.gitmodules' file.

This must be updated to "local", no, to match the change to t1308?

These generally look very good.

I'll queue them with proposed fix-ups, so please do not waste your
time by reworking on your patches in response to my review comments
before fetching today's integration result from the public
repository, which probably will happen in 5 hours or so.

In earlier round(s), this was called config_scope_name(), wasn't it?

"scope_to_string()" is a much worse than "config_scope_name()" as a
name of a global function (e.g. we won't know what subsystems other
than "config" may want to use "scope").  As you remember, Bert's
"remote rename" series wants to use a public interface like this
function, and the series expects this function to be called
config_scope_name().  Let's not rename a public API function
suddenly---it disrupts other topics in flight.

Thanks.

Re: [PATCH v4 6/6] config: add '--show-scope' to print the scope of a config value

[Matt Rogers]

I think this was a mess-up on my end.  I had meant to rename it to
config_scope_name() (after talking with Bert) but it appears that I
had messed up, so I think my mistake wasn't to rename the function, but
to fail to rename it.  So I do apologize.

No need to.  I just wanted to make sure everybody involved is aware
of what others are doing to avoid wasted effort.

Now I do expect the (hopefully) final reroll of your topic, so that
Bert can fork his topic on top of it.

Thanks.

[PATCH v5 0/6] config: allow user to know scope of config options

[Matthew Rogers via GitGitGadget]

This was originally a pull request to the git-for-windows repository
[https://github.com/git-for-windows/git/pull/2399]. It adds a new option
--show-scope which would allow a user to see what scope a given
configuration value has (sytem, local, global, etc.).

changes since v3:

 * Cleaned up t1300
 * Expanded test coverage for t1300 to not rely as much on !MINGW by using a
   simpler filename for most tests
 * config_scope_name is now exposed in config.h
 * cleaned up commit messages for clarity/content (again)

Matthew Rogers (6):
  config: fix typo in variable name
  t1300: fix over-indented HERE-DOCs
  t1300: create custom config file without special characters
  config: split repo scope to local and worktree
  config: clarify meaning of command line scoping
  config: add '--show-scope' to print the scope of a config value

[PATCH v5 1/6] config: fix typo in variable name

[Matthew Rogers via GitGitGadget]

From: Matthew Rogers <mattr94@gmail.com>

In git config use of the end_null variable to determine if we should be
null terminating our output.  While it is correct to say a string is
"null terminated" the character is actually the "nul" character, so this
malapropism is being fixed.

[PATCH v5 3/6] t1300: create custom config file without special characters

[Matthew Rogers via GitGitGadget]

From: Matthew Rogers <mattr94@gmail.com>

Tests that required a custom configuration file to be created previously
used a file with non-alphanumeric characters including escaped double
quotes.  This is not really necessary for the majority of tests
involving custom config files, and decreases test coverage on systems
that dissallow such filenames (Windows, etc.).

Create two files, one appropriate for testing quoting and one
appropriate for general use.

[PATCH v5 4/6] config: split repo scope to local and worktree

[Matthew Rogers via GitGitGadget]

From: Matthew Rogers <mattr94@gmail.com>

Previously when iterating through git config variables, worktree config
and local config were both considered "CONFIG_SCOPE_REPO".  This was
never a problem before as no one had needed to differentiate between the
two cases, but future functionality may care whether or not the config
options come from a worktree or from the repository's actual local
config file.  For example, the planned feature to add a '--show-scope'
to config to allow a user to see which scope listed config options come
from would confuse users if it just printed 'repo' rather than 'local'
or 'worktree' as the documentation would lead them to expect.  As well
as the additional benefit of making the implementation look more like
how the documentation describes the interface.

To accomplish this we split out what was previously considered repo
scope to be local and worktree.

The clients of 'current_config_scope()' who cared about
CONFIG_SCOPE_REPO are also modified to similarly care about
CONFIG_SCOPE_WORKTREE and CONFIG_SCOPE_LOCAL to preserve previous behavior.

From: Matthew Rogers <mattr94@gmail.com>

CONFIG_SCOPE_CMDLINE is generally used in the code to refer to config
values passed in via the -c option.  Options passed in using this
mechanism share similar scoping characteristics with the --file and
--blob options of the 'config' command, namely that they are only in use
for that single invocation of git, and that they supersede the normal
system/global/local hierarchy.  This patch introduces
CONFIG_SCOPE_COMMAND to reflect this new idea, which also makes
CONFIG_SCOPE_CMDLINE redundant.

[PATCH v5 6/6] config: add '--show-scope' to print the scope of a config value

[Matthew Rogers via GitGitGadget]

From: Matthew Rogers <mattr94@gmail.com>

When a user queries config values with --show-origin, often it's
difficult to determine what the actual "scope" (local, global, etc.) of
a given value is based on just the origin file.

Teach 'git config' the '--show-scope' option to print the scope of all
displayed config values.  Note that we should never see anything of
"submodule" scope as that is only ever used by submodule-config.c when
parsing the '.gitmodules' file.

It used to be only "repo"; now we give either "repo" or "worktree".

But the test expects "local".

This patch cannot be correct.  I recall fixing this manually when I
queued the previous round to 'pu'.  Please double check.

There is a trailing SP on this line.  I think I fixed it up when I
queued the last round on 'pu'.  Please double check.

???  Are we using scope_to_string() back again?

I thought I queued a fix-up patch when I queued the last round on
'pu' to unblock the other topic that wanted to build on top.  Please
double check.

Thanks.

[PATCH v6 0/6] config: allow user to know scope of config options

[Matthew Rogers via GitGitGadget]

This was originally a pull request to the git-for-windows repository
[https://github.com/git-for-windows/git/pull/2399]. It adds a new option
--show-scope which would allow a user to see what scope a given
configuration value has (sytem, local, global, etc.).

changes since v4:

 * final cleanups

Matthew Rogers (6):
  config: fix typo in variable name
  t1300: fix over-indented HERE-DOCs
  t1300: create custom config file without special characters
  config: split repo scope to local and worktree
  config: clarify meaning of command line scoping
  config: add '--show-scope' to print the scope of a config value

[PATCH v6 1/6] config: fix typo in variable name

[Matthew Rogers via GitGitGadget]

From: Matthew Rogers <mattr94@gmail.com>

In git config use of the end_null variable to determine if we should be
null terminating our output.  While it is correct to say a string is
"null terminated" the character is actually the "nul" character, so this
malapropism is being fixed.

[PATCH v6 3/6] t1300: create custom config file without special characters

[Matthew Rogers via GitGitGadget]

From: Matthew Rogers <mattr94@gmail.com>

Tests that required a custom configuration file to be created previously
used a file with non-alphanumeric characters including escaped double
quotes.  This is not really necessary for the majority of tests
involving custom config files, and decreases test coverage on systems
that dissallow such filenames (Windows, etc.).

Create two files, one appropriate for testing quoting and one
appropriate for general use.

[PATCH v6 4/6] config: split repo scope to local and worktree

[Matthew Rogers via GitGitGadget]

From: Matthew Rogers <mattr94@gmail.com>

Previously when iterating through git config variables, worktree config
and local config were both considered "CONFIG_SCOPE_REPO".  This was
never a problem before as no one had needed to differentiate between the
two cases, but future functionality may care whether or not the config
options come from a worktree or from the repository's actual local
config file.  For example, the planned feature to add a '--show-scope'
to config to allow a user to see which scope listed config options come
from would confuse users if it just printed 'repo' rather than 'local'
or 'worktree' as the documentation would lead them to expect.  As well
as the additional benefit of making the implementation look more like
how the documentation describes the interface.

To accomplish this we split out what was previously considered repo
scope to be local and worktree.

The clients of 'current_config_scope()' who cared about
CONFIG_SCOPE_REPO are also modified to similarly care about
CONFIG_SCOPE_WORKTREE and CONFIG_SCOPE_LOCAL to preserve previous behavior.

[PATCH v6 5/6] config: clarify meaning of command line scoping

[Matthew Rogers via GitGitGadget]

From: Matthew Rogers <mattr94@gmail.com>

CONFIG_SCOPE_CMDLINE is generally used in the code to refer to config
values passed in via the -c option.  Options passed in using this
mechanism share similar scoping characteristics with the --file and
--blob options of the 'config' command, namely that they are only in use
for that single invocation of git, and that they supersede the normal
system/global/local hierarchy.  This patch introduces
CONFIG_SCOPE_COMMAND to reflect this new idea, which also makes
CONFIG_SCOPE_CMDLINE redundant.

[PATCH v6 6/6] config: add '--show-scope' to print the scope of a config value

[Matthew Rogers via GitGitGadget]

From: Matthew Rogers <mattr94@gmail.com>

When a user queries config values with --show-origin, often it's
difficult to determine what the actual "scope" (local, global, etc.) of
a given value is based on just the origin file.

Teach 'git config' the '--show-scope' option to print the scope of all
displayed config values.  Note that we should never see anything of
"submodule" scope as that is only ever used by submodule-config.c when
parsing the '.gitmodules' file.

Indeed.  This round looks good.

for clarity, I think this patch should be split up further.

For example:

  - moving an enum and adding a new entry should be avoided
  - does the changes to '/config.c' fix something?
  - exposing config_scope_name should have been done before PATCH 4/6 already

Best,
Bert

Re: [PATCH v6 6/6] config: add '--show-scope' to print the scope of a config value

As far as adding a new entry, that could probably be done in a separate patch.
The submodule scoping is correct (mostly so config options that come from
submodule blobs have a sane value to set the new scope field of
git_config_source), but moving it is unavoidable as I'd either have to move
config_scope or git_config_source for this patch to work, and moving
git_config_source seemed like a ton more work

>   - does the changes to '/config.c' fix something?

Another thing, that in hindsight could probably be split out. The other changes
do fix the fact that previously recursive calls to do_git_config_sequence()
would blow awway the current_parsing_scope information for higher level callers.
This is not super common, but does occur when --show-scope is used with the
--blob option.

>   - exposing config_scope_name should have been done before PATCH 4/6 already

If that's better/more convenient, I don't have a problem breaking that
out and moving
it there.

Alright.  Thanks for another round of review.

[PATCH v7 00/10] config: allow user to know scope of config options

[Matthew Rogers via GitGitGadget]

This was originally a pull request to the git-for-windows repository
[https://github.com/git-for-windows/git/pull/2399]. It adds a new option
--show-scope which would allow a user to see what scope a given
configuration value has (sytem, local, global, etc.).

changes since v6: Split patch 6: config: add '--show-scope'... into several
parts, including moving the exposure of config_scope_name into its own
commit earlier in the series.

Matthew Rogers (10):
  config: fix typo in variable name
  t1300: fix over-indented HERE-DOCs
  t1300: create custom config file without special characters
  config: make scope_name non-static and rename it
  config: split repo scope to local and worktree
  config: clarify meaning of command line scoping
  config: preserve scope in do_git_config_sequence
  config: teach git_config_source to remember its scope
  submodule-config: add subomdule config scope
  config: add '--show-scope' to print the scope of a config value

[PATCH v7 01/10] config: fix typo in variable name

[Matthew Rogers via GitGitGadget]

From: Matthew Rogers <mattr94@gmail.com>

In git config use of the end_null variable to determine if we should be
null terminating our output.  While it is correct to say a string is
"null terminated" the character is actually the "nul" character, so this
malapropism is being fixed.

[PATCH v7 03/10] t1300: create custom config file without special characters

[Matthew Rogers via GitGitGadget]

From: Matthew Rogers <mattr94@gmail.com>

Tests that required a custom configuration file to be created previously
used a file with non-alphanumeric characters including escaped double
quotes.  This is not really necessary for the majority of tests
involving custom config files, and decreases test coverage on systems
that dissallow such filenames (Windows, etc.).

Create two files, one appropriate for testing quoting and one
appropriate for general use.

[PATCH v7 04/10] config: make scope_name non-static and rename it

[Matthew Rogers via GitGitGadget]

From: Matthew Rogers <mattr94@gmail.com>

To prepare for the upcoming --show-scope option, we require the ability
to convert a config_scope enum to a string.  As this was originally
implemented as a static function 'scope_name()' in
t/helper/test-config.c, we expose it via config.h and give it a less
ambiguous name 'config_scope_name()'

and local config were both considered "CONFIG_SCOPE_REPO".  This was
never a problem before as no one had needed to differentiate between the
two cases, but future functionality may care whether or not the config
options come from a worktree or from the repository's actual local
config file.  For example, the planned feature to add a '--show-scope'
to config to allow a user to see which scope listed config options come
from would confuse users if it just printed 'repo' rather than 'local'
or 'worktree' as the documentation would lead them to expect.  As well
as the additional benefit of making the implementation look more like
how the documentation describes the interface.

To accomplish this we split out what was previously considered repo
scope to be local and worktree.

The clients of 'current_config_scope()' who cared about
CONFIG_SCOPE_REPO are also modified to similarly care about
CONFIG_SCOPE_WORKTREE and CONFIG_SCOPE_LOCAL to preserve previous behavior.

[PATCH v7 06/10] config: clarify meaning of command line scoping

[Matthew Rogers via GitGitGadget]

From: Matthew Rogers <mattr94@gmail.com>

CONFIG_SCOPE_CMDLINE is generally used in the code to refer to config
values passed in via the -c option.  Options passed in using this
mechanism share similar scoping characteristics with the --file and
--blob options of the 'config' command, namely that they are only in use
for that single invocation of git, and that they supersede the normal
system/global/local hierarchy.  This patch introduces
CONFIG_SCOPE_COMMAND to reflect this new idea, which also makes
CONFIG_SCOPE_CMDLINE redundant.

[PATCH v7 07/10] config: preserve scope in do_git_config_sequence

[Matthew Rogers via GitGitGadget]

From: Matthew Rogers <mattr94@gmail.com>

do_git_config_sequence operated under the assumption that it was correct
to set current_parsing_scope to CONFIG_SCOPE_UNKNOWN as part of the
cleanup it does after it finishes execution.  This is incorrect, as it
blows away the current_parsing_scope if do_git_config_sequence is called
recursively.  As such situations are rare (git config running with the
'--blob' option is one example) this has yet to cause a problem, but the
upcoming '--show-scope' option will experience issues in that case, lets
teach do_git_config_sequence to preserve the current_parsing_scope from
before it started execution.

[PATCH v7 08/10] config: teach git_config_source to remember its scope

[Matthew Rogers via GitGitGadget]

From: Matthew Rogers <mattr94@gmail.com>

There are many situations where the scope of a config command is known
beforehand, such as passing of '--local', '--file', etc. to an
invocation of git config.  However, this information is lost when moving
from builtin/config.c to /config.c.  This historically hasn't been a big
deal, but to prepare for the upcoming --show-scope option we teach
git_config_source to keep track of the source and the config machinery
to use that information to set current_parsing_scope appropriately.

[PATCH v7 09/10] submodule-config: add subomdule config scope

[Matthew Rogers via GitGitGadget]

From: Matthew Rogers <mattr94@gmail.com>

Before the changes to teach git_config_source to remember scope
information submodule-config.c never needed to consider the question of
config scope.  Even though zeroing out git_config_source is still
correct and preserved the previous behavior of setting the scope to
CONFIG_SCOPE_UNKNOWN, it's better to be explicit about such situations
by explicitly setting the scope.  As none of the current config_scope
enumerations make sense we create CONFIG_SCOPE_SUBMODULE to describe the
situation.

[PATCH v7 10/10] config: add '--show-scope' to print the scope of a config value

[Matthew Rogers via GitGitGadget]

From: Matthew Rogers <mattr94@gmail.com>

When a user queries config values with --show-origin, often it's
difficult to determine what the actual "scope" (local, global, etc.) of
a given value is based on just the origin file.

Teach 'git config' the '--show-scope' option to print the scope of all
displayed config values.  Note that we should never see anything of
"submodule" scope as that is only ever used by submodule-config.c when
parsing the '.gitmodules' file.

The change from "cmdline" to "command line" does need to happen
before the end of the series, but I do not think it should happen
here, especialy given that the proposed log message explains that
this step is to expose scope_name() under a better name (which is a
very good split point).

How are you reviewing the patches in your own series before sending
them out?  This round is better than the previous rounds where we
didn't have a matching change to the tests so "make test" may not
have passed in the middle of the series, though...

Makes sense.  And this step does exactly what it claims to do and

This makes sense, even though it is halfway undoing what 04/10
unnecessarily did ;-)

I think I can just wiggle minor fixes in to 04/10 and then adjust
this one to get the series into a better shape myself before queuing
them to expedite the process.  Let me finish reading the remainder
of the topic.

I went through each patch individually using rebase -i and built/tested it.
Although just to save time I only did t1300 and t1308 since I believe those were
the only ones that should be affected.  I can write a script that
would run the whole
test suite overnight for me and make sure the series shakes out okay,
if you'd like.

Not sure whether you intend to do this or not, but to maybe save you
some scripting, I do this like so:

  git rebase -x \
    "make -j16 && (cd t && prove -j16 -v --shuffle t[0-9]*.sh)" master

If the tests fail, the rebase is paused, which can be understandably
disappointing if you walk away from it overnight only to have it fail
after 10 minutes, though. :)

What I like does not matter.  

What I pointed out for 04/10 wouldn't have been caught by your
testing anyway, as both the code and the test had matching
unnecessry changes.  I was wondering if you are relying too heavily
on just tests and without actually proofreading the changes to see
if they still make sense in the context of the updated series, and
if my suspicion was correct, if there are something reviewers can do
to help the authors.

I do try to proofread patches, I'm just not the most careful of reviewers at
times, partially as a personal problem and partially as this is a new workflow
for me.  As for the particular issue, I just thought it was a good idea at the
time and I didn't think it all the way through
