This topic branch depends on the patch mailed in
lore.kernel.org/git/20191211233820.185153-1-emilyshaffer@google.com in order to
display scopes for configs gathered during "bugreport: add config values from
safelist".
Quite a few changes since v3. I'll try to summarize the big picture
stuff, plus highlight new changes and difference in patches inline in
the commit list. I'll also stick an interdiff since v3 at the bottom of
this cover letter.
Some overall changes:
- The entire command now exists in one file, bugreport.c, which is
compiled as a standalone.
- static-ness of local functions has been cleaned up.
- strbuf lifetime management has been cleaned up.
- Mention of "whitelist" and "blacklist" has been changed to "safelist"
and "blocklist" while dealing with Git-approved bugreportable configs.
Thanks Dscho for pointing this out; "safelist" makes sense to me as
these are configs we have deemed safe for public inspection.
- Inquiry into both Git's $SHELL_PATH and the user's $SHELL is new to
v4.
- The 'man git bugreport' page which was lost from the script version of
git-bugreport has been recovered, as have the "tests" (which only test
whether it runs and doesn't crash).
Emily Shaffer (15):
bugreport: add tool to generate debugging info
Moved from library + builtin to a standalone git-bugreport binary.
help: move list_config_help to builtin/help
Resolves a circular dependency where using help.o required all builtins
to exist. This also moves generation of config-list.h into its own
script (it was previously roommates with command-list.h).
The following 4 commits were previously a single commit which used
run-command.h to call different processes; this has been removed except
for the cURL version.
bugreport: gather git version and build info
Additionally capture the "--build-info" output from 'git version' where it
was not previously captured.
help: add shell-path to --build-options
Adding $SHELL_PATH to 'git --version --build-options' gets it in the
bugreport for free. (This is the shell Git uses, determined at build
time.)
bugreport: add uname info
Capture uname from the library instead of invoking a different process.
bugreport: add glibc version
Capture glibc version info from the library instead of invoking the
'ldd' process.
bugreport: add curl version
Capture the cURL version from git-http-fetch, and add a -V flag to that
binary for this purpose.
bugreport: include user interactive shell
A new feature; check what $SHELL the user is using (at runtime)
bugreport: generate config safelist based on docs
This commit squashes in suggestions both from Johannes Schindelin and
Martin Ågren, hopefully resulting in Asciidoc(tor) not showing the
safelist macros, and a more portable safelist generation script. It also
puts the safelist, sorted, directly into a header instead of into a text
file, saving us a file read at runtime.
bugreport: add config values from safelist
At Dscho's suggestion, now we put these into a map (based on khash and
oidset.h's example) for constant-time lookup during the config parse.
bugreport: collect list of populated hooks
Only a minor change - now this works if 'git bugreport' is invoked
outside of a Git repo.
bugreport: count loose objects
bugreport: add packed object summary
bugreport: list contents of $OBJDIR/info
For the above 3, the entire 'string_list' has been refactored out; now
the obj_info buffer is written to directly during the directory
traversal. Also paid more attention to when to free strbuf used for paths.
bugreport: summarize contents of alternates file
Rather than printing the contents of the alternates file, now the number
of specified alternate stores are listed, and they are tested to check
whether they exist. This way we stop looking at user filepaths
(sensitive) and start learning whether they have a broken alternate (new
and useful info).

+
+The following information is requested from the user:
+
+ - Reproduction steps
+ - Expected behavior
+ - Actual behavior
+
+The following information is captured automatically:
+
+ - Git version (`git version --build-options`)
+ - Machine information (`uname -a`)
+ - Versions of various dependencies
+ - Git config contents (`git config --show-origin --list`)
+ - The names of all configured git-hooks in `.git/hooks/`

Teach Git how to prompt the user for a good bug report: reproduction
steps, expected behavior, and actual behavior. Later, Git can learn how
to collect some diagnostic information from the repository.
If users can send us a well-written bug report which contains diagnostic
information we would otherwise need to ask the user for, we can reduce
the number of question-and-answer round trips between the reporter and
the Git contributor.
Users may also wish to send a report like this to their local "Git
expert" if they have put their repository into a state they are confused
by.

+================
+
+NAME
+----
+git-bugreport - Collect information for user to file a bug report
+
+SYNOPSIS
+--------
+[verse]
+'git bugreport' [-o | --output <path>]
+
+DESCRIPTION
+-----------
+Captures information about the user's machine, Git client, and repository state,
+as well as a form requesting information about the behavior the user observed,
+into a single text file which the user can then share, for example to the Git
+mailing list, in order to report an observed bug.
+
+The following information is requested from the user:
+
+ - Reproduction steps
+ - Expected behavior
+ - Actual behavior
+
+The following information is captured automatically:
+
+ - Git version (`git version --build-options`)
+ - Machine information (`uname -a`)
+ - Versions of various dependencies
+ - Git config contents (`git config --show-origin --list`)
+ - The names of all configured git-hooks in `.git/hooks/`
+
+OPTIONS
+-------
+-o [<path>]::
+--output [<path>]::
+ Place the resulting bug report file in <path> instead of the root of the
+ Git repository.

Starting in 3ac68a93fd2, help.o began to depend on builtin/branch.o,
builtin/clean.o, and builtin/config.o. This meant that help.o was
unusable outside of the context of the main Git executable.
To make help.o usable by other commands again, move list_config_help()
into builtin/help.c (where it makes sense to assume other builtin libraries
are present).
When command-list.h is included but a member is not used, we start to
hear a compiler warning. Since the config list is generated in a fairly
different way than the command list, and since commands and config
options are semantically different, move the config list into its own
header and move the generator into its own script and build rule.

Knowing which version of Git a user has and how it was built allows us
to more precisely pin down the circumstances when a certain issue
occurs, so teach bugreport how to tell us the same output as 'git
version --build-options'.
It's not ideal to directly call 'git version --build-options' because
that output goes to stdout. Instead, wrap the version string in a helper
within help.[ch] library, and call that helper from within the bugreport
library.

It may be useful to know which shell Git was built to try to point to,
in the event that shell-based Git commands are failing. $SHELL_PATH is
set during the build and used to launch the manpage viewer, as well as
by git-compat-util.h, and it's used during tests. 'git version
--build-options' is encouraged for use in bug reports, so it makes sense
to include this information there.

The contents of uname() can give us some insight into what sort of
system the user is running on, and help us replicate their setup if need
be. The domainname field is not guaranteed to be available, so don't
collect it.

To help pinpoint the source of a regression, it is useful to know the
version of libc which the user's Git client was built with. Let's
include it alongside the other versioning information, which is used to
identify how the client was built.

It's possible for git-http* to be built separately from git; in that
case we want to know what version of cURL is used by git-http*, not
necessarily which version was present at git-bugreport's build time.
So instead, ask git-http-fetch for the version information it knows
about.
git-http-fetch was chosen as git-http-backend was described as a
server-side implementation, and as an accidental fetch in case of
problems was considered less harmful than an accidental push.
Since it could have been built at a different time, also report the
version and built-from commit of git-http-fetch alongside the cURL info.

It's possible a user may complain about the way that Git interacts with
their interactive shell, e.g. autocompletion or shell prompt. In that
case, it's useful for us to know which shell they're using
interactively.
$SHELL isn't set by every shell, but getenv() returns NULL in the
event the variable isn't found, so we'll see a line like "$SHELL:
(null)" to tell us that variable wasn't set.

Add a new step to the build to generate a safelist of git-config
variables which are appropriate to include in the output of
git-bugreport. New variables can be added to the safelist by annotating
their documentation in Documentation/config with the
"bugreport" macro, which is recognized by AsciiDoc and
AsciiDoctor.
Some configs are private in nature, and can contain remote URLs,
passwords, or other sensitive information. In the event that a user
doesn't notice their information while reviewing a bugreport, that user
may leak their credentials to other individuals, mailing lists, or bug
tracking tools inadvertently. Heuristic blocklisting of configuration
keys is imperfect and prone to false negatives; given the nature of the
information which can be leaked, a safelist is more reliable.
In order to prevent staleness of the safelist, add a mechanism to
generate the safelist from annotations in the config documentation,
where contributors are already used to documenting their new config
keys.
Implement a new no-op "bugreport" macro for use as
"bugreport:include[x]" to annotate the config keys that should be
included in the automatically generated safelist. Use "exclude" for the
others.
With Asciidoctor, it's ok to say "bugreport:include[]", but AsciiDoc
seems to want something between the brackets. A bit unfortunate, but
not a huge problem -- we'll just provide an "x".
"doc-diff" reports that this macro doesn't render at all. That is,
these are both empty after this commit:
cd Documentation
./doc-diff --asciidoctor :/"bugreport: add tool" HEAD
./doc-diff --asciidoc :/"bugreport: add tool" HEAD
Diffing the rendered HTML shows that there is some small amount of
whitespace and comments added. That shouldn't be a problem.
We could perhaps let the implementation verify that the "action" is one
of "include" and "exclude". For the Asciidoctor implementation that
should be straightforward, but for AsciiDoc I don't immediately know how
to do it. Anyway, if someone stumbles on the keyboard and writes
"bugreport:icndule", they'll "only" miss out on the config key being
included in the safelist. If this were a blocklist, the consequences of
a misspelled target could be a lot more severe.
Additionally, add annotations to the sendemail config documentation in
order to demonstrate a proof of concept.

Teach bugreport to gather the values of config options which are present
in 'bugreport-config-safelist.h'.
Many config options are sensitive, and many Git add-ons use config
options which git-core does not know about; it is better only to gather
config options which we know to be safe, rather than excluding options
which we know to be unsafe.
Taking the build-time generated array and putting it into a set saves us
time - since git_config_bugreport() is called for every option the user
has configured, performing option lookup in constant time is a useful
optimization.

Occasionally a failure a user is seeing may be related to a specific
hook which is being run, perhaps without the user realizing. While the
contents of hooks can be sensitive - containing user data or process
information specific to the user's organization - simply knowing that a
hook is being run at a certain stage can help us to understand whether
something is going wrong.
Without a definitive list of hook names within the code, we compile our
own list from the documentation. This is likely prone to bitrot. To
reduce the amount of code humans need to read, we turn the list into a
string_list and iterate over it (as we are calling the same find_hook
operation on each string). However, since bugreport should primarily be
called by the user, the performance loss from massaging the string
seems acceptable.

The number of unpacked objects in a user's repository may help us
understand the root of the problem they're seeing, especially if a
command is running unusually slowly.
Rather than directly invoking 'git-count-objects', which may sometimes
fail unexpectedly on Git for Windows, manually count the contents of
.git/objects. Additionally, since we may wish to inspect other
directories' contents for bugreport in the future, put the directory
listing into a helper function.

Alongside the list of loose objects, it's useful to see the list of
object packs as well. It can help us to examine what Git did and did not
pack.

Miscellaneous information used about the object store can end up in
.git/objects/info; this can help us understand what may be going on with
the object store when the user is reporting a bug. Otherwise, it could
be difficult to track down what is going wrong with an object which
isn't kept locally to .git/objects/ or .git/objects/pack. Having some
understanding of where the user's objects may be kept can save us some
hops during the bug reporting process.

In some cases, it could be that the user is having a problem with an
object which isn't present in their normal object directory. We can get
a hint that that might be the case by examining the list of alternates
where their object may be stored instead. Since paths to alternates may
be sensitive, we'll instead count how many alternates have been
specified and note how many of them exist or are broken.

Move to strbuf() from stdio makes sense.

Many new helpers are called get_frotz(), but only one among these is
called list_version_info(). I do not think the naming of the
get_*() ones, that are private to the bugreport tool, matters that
much, but unlike "list_commands()" whose purpose is to list the
commands ;-), the new function does not list versions---it just
gives information about a single version which is the one that is
being run, so perhaps it is a misnomer.

It is not clear to the readers build_options is a boolean that
tells the function to include (or not to include) build options.
Perhaps rename it to "int show_build_options" or something?

It was surprising to me that we do use "struct utsname" somewhere in
the system ;-) ... so at least we know this is just as portable as
the remainder of Git, which is good.

This is the first iffy one in the series. It is unreasonable to
assume that we can dictate that Git can be built only on glibc
systems, no?
Making this conditional, perhaps make "bugreport.c" depend on
"extern void get_compiler_info(struct strbuf *sys_info)" and require
the function to be defined in compat/; the glibc variant that uses
gnu_get_libc_version() would become just one of them.

One possible issue I have is that I was hoping that eventually we
can discard "git http-fetch" altogether sometime in the future.
Does anybody still use the dumb HTTP transport seriously?
And the first move in that direction would be to allow the system be
built without http-fetch, even if git-remote-curl (and its aliases)
would still be built to access smart-http transports.
So, I am not sure. This is just the matter of adding an out-of-line
hidden option used only for environment inspection, so if it can be
done to git-remote-curl, that would probably be much more future
proof.

OK. We probably can also take the compile-time "NO_CURL" into account,
so that we can tell a misconfigured installation that wanted to have
CURL but failed to install a usable http-fetch and an installation
that deliberately omitted anything cURL?

Do not depend on vsnprintf() from glibc that accepts NULL and shows
"(null)". You can segfault on systems without glibc that way.

Interesting. I actually was expecting the look-up to go the other
way around. We know the safe keys, so iterate over them and grab
their values, if defined. No need for hashes or anything, but just
a simple linear list of safe stuff.
But that is too simple-minded. If we wanted to safelist foo.*.bar,
where '*' can be anything, walking on the list of safe variables
would not work. We must have a hash table that knows "foo.*.bar" is
allowed, and while walking all the configuration keys, when we see
foo.a.bar, we consult "foo.*.bar" as well as "foo.a.bar" to see if
it is whitelisted, or something like that.
But then I am not sure if this implementation does something like
this for three-level names. If not, I do not see much point in use
of the hash there either.
Puzzled.

We probably would want to employ technique similar to what you used
for the list of safe configuration we saw in an earlier patch in the

Is for_each_loose_object() or for_each_loose_file_in_objdir() not
sufficient? We really do *not* want a redundant implementation of
something we already use elsewhere in the system, especially for the
purpose of this program, because you would end up reporting what you
computed in a way that may be quite different from what the rest of
the system that is actually used by the end users computes.

Not exactly the same comment, but is in the same spirit, as the
previous step applies to this one.
Would it be too much work to libify the bulk of cmd_count_objects()
that computes numbers, making the cmd_count_objects() into a thin
wrapper that calls the libified "counter/collector" function and
prints the resulting numbers received from it?
That way, the get_packed_object_summary() can be another consumer
of the same "counter/collector" function, no?

But bugreport.o needs this *.h file generated before a compiler
attempts to produce it out of bugreport.c; that dependency is
missing from this update to the Makefile.

It is kind of sad that GEN_HDRS defines the list of build artifact
that we should be able to clean, and then we manually list them to
be removed here independently. Can we fix it up too?
We probably clean up the build/update procedure around unicode-width.h
before we can do so, probably. It may be generatable using contrib/
script, but as far as our normal build is concerned, it is a tracked
source and not part of the build byproducts, so we probably would
want to remove it from GEN_HDRS. When that happens, we can $(RM)
all of the $(GEN_HDRS) in the "clean" target.

If you use `/ "\1",/` as replacement, you can totally avoid that ugly
`while` loop (that is unfortunately quite slow in MSYS2/Cygwin). You can
still pipe the result into `sort` just the same.

Ok. Are you going to take it on its own? If so, I'll be relying on two
branches in pu/ - what's the best way to let you know I need them both
if/when I send another version of this chain?

Not really. Unless you abandon the rest of the topic, in which case
it may be worth resurrecting this one on its own, that is. But that
is not what you plan to do anyway, so I expect to see it as part of
an updated series ;-)

Interesting. This sounds like a good approach - thanks, I'll look into

Oh, interesting. I was about to say, "I still use it to fetch, when I
don't really care" - but that isn't even true, as I fetch via https (and
have so much muscle memory to type https that I don't even notice).`

Ok. I'll move it.

Hm. Somewhere I misformatted my commits, then. My goal was to add the
new header here, but not add it as a dependency to anybody; then, in the
next commit, add it as a dependency to git-bugreport and start to use it
(commit 1: make the thing; commit 2: use the thing). But now when I look
at the next commit, I don't see a Makefile change. So I missed something
while I was shuffling around fixups. Thanks for noticing.

Yeah, I can do that. I thought so too when I was updating this.
I *think* what happened is that when I split config-list away (in the
earleir commit in this chain) I didn't notice that command-list.h was
already in GEN_HDRS, and instead just grepped Makefile for
"command-list.h" and added config-list.h next to it. So I'll try to fix
it much earlier, in that commit, and then simply add to the appropriate
variables in this commit.

Hm. Without looking at the code, I said to myself,
"repo_config_get_value() will open all the available config files to
find the resolved value, so I don't want to do n*4 file open/closes, I
only want to do 4 total."
Now I look at the code and see that the configs are already being read
into a hashset before now. So you're right that it doesn't make sense
for me to do it this way....

...unless we want to use wildcards like you suggest.
But I'm not sure it's a good idea. I envision someone writing another
Git add-on, which offers someone to specify "user.password" and
automagically do some Bitbucket interaction, or something. (An extreme
and misguided example, but I hope the point remains.) Then if I say,
"all the user.* configs I can see in 'git help config' are safe, so I
will just safelist user.*," I'm not accounting for this other tool's
known configs which are a superset of what Git knows and expects.
The point of this safelist-generation exercise is to avoid accidentally
printing some sensitive user config, and the point of using a safelist
instead of a blocklist is to avoid printing a third-party config we
didn't know about (or messing up our pattern matching). So I suggest we
avoid pattern matching entirely.

I'd prefer to solve it by iterating over the compile-time-generated
safelist using get_config_value_multi(), which I clock at O(n) for n =
safelist length: performing n calls to an O(1) hashset lookup. That
saves us the O(n*log(n)) hashset population, and the implementation of
Yet Another Set in the source.
Thanks.

I somewhat slightly would rather not, since I hope to include a list of
the available hooks in my work with git-hook:
https://lore.kernel.org/20191211205114.GD107889@google.com
It's true that the way this patch is written now is prone to bitrot.
It's also true that I could win the lottery tomorrow and never finish my
hopes of git-hook implementation. And it's finally true that I don't
want to write a fourth build-time-generated header which scrapes docs,
especially if I also plan to delete it two months from now.
I wonder whether a better approach might be to drop hook support
entirely here, and add it later on when this particular bit of tech debt
(no canonical list of hook names) is solved, one way or another.
Another approach may be to just list all contents of $(core.hookdir)/
which doesn't end in ".sample", which is what the bash first attempt of
bugreport did. This does mean that those who have something like:
.git/hooks/
pre-commit
pre-commit.d/
pre-commit:
sh pre-commit.d/a
sh pre-commit.d/b
will have their multihook config exposed, although the contents of those
hooks won't be.
I'm interested to know everyone else's opinion, because mine is biased
by my hope that I can solve all the world's problems with git-hook ;)

Oh, thanks for the pointer. That looks sufficient - I will investigate

Wildcarding the leaf level of two (or for that matter three) level
names like "user.*" in your example is of course a nonsense way to
use the safelist. But think about three-level names where the
second level is designed to be used for user-supplied token to give
things of similar nature a name the user can use to distinguish
things. If remote.origin.url is worth reporting, wouldn't
remote.upstream.url also be? Shouldn't remote.*.url be the way to
say "the URL field for each and every remote is a safe thing to
report" in the safelist?

The "StaticAnalysis" job of the Azure Pipeline is not happy with this,
claiming that this should be an `strbuf_addstr()` call instead. For
details, see:

You mean the "else" clause, right? That feels similar to say
printf("Hello world\n");
should better be written as
fputs("Hello world\n", stdout);
which I do not agree with at all. IOW, I view the distinction more
like "once it is written one way or the other way, it is not worth
spending bits and braincycles to see if it is worth changing it"
kind of minor stylistic preference.

I think I side with Junio here, although it's true that when
strbuf_addstr() exists it doesn't make that much sense to use
strbuf_addf(). Since there's some other comments, though, I'll change
this too to make your CI shut up. :)

Sure, dropped this entirely. I think with the helpers the code is
self-documenting there.

Hm, sure. I renamed it to get_version_info(); I had named it list_*
because all the other helpers in help.h are named list_*, and it does
print more than one piece of info. But I do see your point (all the info
is about the same version) so I've renamed it.

The manpage on Linux says that it's a GNU extension; on Mac OS it isn't
mentioned. So it would be more accurate to say that it's known not to be
available on many systems rather than just not being guaranteed.
Besides that I think in some cases it may be considered sensitive
information, so another reason to not include it. Perhaps even worthy of
being mentioned as the primary reason.
>+ uname_info.nodename,
I think in some cases this could also be considered as sensitive
information, and is unlikely to help in diagnosing problems. So I'd
move to exclude this as well.

Bah, somehow this mail slipped through the cracks for me.
When you put it that way, I see how it can be useful. Although I admit
to fatigue on this patchset and now I'm hesitant about feature creep. :)
I'm going to send the reroll for v5 as I have it, not having seen this
mail, and think more about how I'd approach wildcarding in the middle
like this. I want to take a look at the other configs which use a middle
level as a user token and try to reason about whether we ought to be
collecting them. I'll hope to report back sooner (or later).

From: Emily Shaffer <emilyshaffer@google.com>
This topic branch depends on the patch mailed in
lore.kernel.org/git/20191211233820.185153-1-emilyshaffer@google.com in order to
display scopes for configs gathered during "bugreport: add config values from
safelist".
I'll summarize v4-v5. Since v4 has languished for some time, I don't
think an interdiff is too helpful, so I won't include one. Bonus, the
code is much simplified from some suggestions from Junio on how to
inspect objects, so I hope it's easy to review anyways.
Throughout, did some style changes away from C++ bad habits. Otherwise,
as listed:
Emily Shaffer (15):
bugreport: add tool to generate debugging info
(no change)
help: move list_config_help to builtin/help
Changed to agree with f3719846134
bugreport: gather git version and build info
Style only
help: add shell-path to --build-options
(no change)
bugreport: add uname info
Removed nodename for privacy reasons
bugreport: add compiler info
Moved glibc tattling into compat/.
I appreciate a close look at this one - I think I understood the
right way to go about a compat/ util but it's the first one I've
done.
bugreport: add curl version
Moved curl tattling from git-http-fetch into git-remote-curl
bugreport: include user interactive shell
Stop depending on a compiler quirk to save us from segfault
bugreport: generate config safelist based on docs
Changed to agree with f3719846134
Cleaned up script a little
bugreport: add config values from safelist
Made git-bugreport dependent on generated safelist header
bugreport: collect list of populated hooks
No change.
Per https://lore.kernel.org/git/20191216235131.GL135450@google.com,
should we even keep this patch?
bugreport: count loose objects
Use helpers from object-store.h instead of manually walking the
filesystem.
bugreport: add packed object summary
Use helpers from object-store.h instead of manually walking the
filesystem.
bugreport: list contents of $OBJDIR/info
(no change)
bugreport: summarize contents of alternates file
Rephrase commit message to explain why I can't use the helpers in
object-store.h.
Thanks.
- Emily

Teach Git how to prompt the user for a good bug report: reproduction
steps, expected behavior, and actual behavior. Later, Git can learn how
to collect some diagnostic information from the repository.
If users can send us a well-written bug report which contains diagnostic
information we would otherwise need to ask the user for, we can reduce
the number of question-and-answer round trips between the reporter and
the Git contributor.
Users may also wish to send a report like this to their local "Git
expert" if they have put their repository into a state they are confused
by.

+NAME
+----
+git-bugreport - Collect information for user to file a bug report
+
+SYNOPSIS
+--------
+[verse]
+'git bugreport' [-o | --output <path>]
+
+DESCRIPTION
+-----------
+Captures information about the user's machine, Git client, and repository state,
+as well as a form requesting information about the behavior the user observed,
+into a single text file which the user can then share, for example to the Git
+mailing list, in order to report an observed bug.
+
+The following information is requested from the user:
+
+ - Reproduction steps
+ - Expected behavior
+ - Actual behavior
+
+The following information is captured automatically:
+
+ - Git version (`git version --build-options`)
+ - Machine information (`uname -a`)
+ - Versions of various dependencies
+ - Git config contents (`git config --show-origin --list`)
+ - The names of all configured git-hooks in `.git/hooks/`
+
+OPTIONS
+-------
+-o [<path>]::
+--output [<path>]::
+ Place the resulting bug report file in <path> instead of the root of the
+ Git repository.

Starting in 3ac68a93fd2, help.o began to depend on builtin/branch.o,
builtin/clean.o, and builtin/config.o. This meant that help.o was
unusable outside of the context of the main Git executable.
To make help.o usable by other commands again, move list_config_help()
into builtin/help.c (where it makes sense to assume other builtin libraries
are present).
When command-list.h is included but a member is not used, we start to
hear a compiler warning. Since the config list is generated in a fairly
different way than the command list, and since commands and config
options are semantically different, move the config list into its own
header and move the generator into its own script and build rule.

Knowing which version of Git a user has and how it was built allows us
to more precisely pin down the circumstances when a certain issue
occurs, so teach bugreport how to tell us the same output as 'git
version --build-options'.
It's not ideal to directly call 'git version --build-options' because
that output goes to stdout. Instead, wrap the version string in a helper
within help.[ch] library, and call that helper from within the bugreport
library.

It may be useful to know which shell Git was built to try to point to,
in the event that shell-based Git commands are failing. $SHELL_PATH is
set during the build and used to launch the manpage viewer, as well as
by git-compat-util.h, and it's used during tests. 'git version
--build-options' is encouraged for use in bug reports, so it makes sense
to include this information there.

be. The domainname field is not guaranteed to be available, so don't

To help pinpoint the source of a regression, it is useful to know some
info about the compiler which the user's Git client was built with. By
adding a generic get_compiler_info() in 'compat/' we can choose which
relevant information to share per compiler; to get started, let's
demonstrate the version of glibc if the user built with 'gcc'.

It's possible for git-remote-curl to be built separately from git; in that
case we want to know what version of cURL is used by git-remote-curl, not
necessarily which version was present at git-bugreport's build time.
So instead, ask git-remote-curl for the version information it knows
about.
For longevity purposes, invoke the alias "git-remote-https" instead of
"git-remote-http".
Since it could have been built at a different time, also report the
version and built-from commit of git-remote-curl alongside the cURL info.

It's possible a user may complain about the way that Git interacts with

case, it's useful for us to know which shell they're using

From: Emily Shaffer <emilyshaffer@google.com>
Add a new step to the build to generate a safelist of git-config
variables which are appropriate to include in the output of
git-bugreport. New variables can be added to the safelist by annotating
their documentation in Documentation/config with the
"bugreport" macro, which is recognized by AsciiDoc and
AsciiDoctor.
Some configs are private in nature, and can contain remote URLs,
passwords, or other sensitive information. In the event that a user
doesn't notice their information while reviewing a bugreport, that user
may leak their credentials to other individuals, mailing lists, or bug
tracking tools inadvertently. Heuristic blocklisting of configuration
keys is imperfect and prone to false negatives; given the nature of the
information which can be leaked, a safelist is more reliable.
In order to prevent staleness of the safelist, add a mechanism to
generate the safelist from annotations in the config documentation,
where contributors are already used to documenting their new config
keys.
Implement a new no-op "bugreport" macro for use as
"bugreport:include[x]" to annotate the config keys that should be
included in the automatically generated safelist. Use "exclude" for the
others.
With Asciidoctor, it's ok to say "bugreport:include[]", but AsciiDoc
seems to want something between the brackets. A bit unfortunate, but
not a huge problem -- we'll just provide an "x".
"doc-diff" reports that this macro doesn't render at all. That is,
these are both empty after this commit:
cd Documentation
./doc-diff --asciidoctor :/"bugreport: add tool" HEAD
./doc-diff --asciidoc :/"bugreport: add tool" HEAD
Diffing the rendered HTML shows that there is some small amount of
whitespace and comments added. That shouldn't be a problem.
We could perhaps let the implementation verify that the "action" is one
of "include" and "exclude". For the Asciidoctor implementation that
should be straightforward, but for AsciiDoc I don't immediately know how
to do it. Anyway, if someone stumbles on the keyboard and writes
"bugreport:icndule", they'll "only" miss out on the config key being
included in the safelist. If this were a blocklist, the consequences of
a misspelled target could be a lot more severe.
Additionally, add annotations to the sendemail config documentation in
order to demonstrate a proof of concept.

Teach bugreport to gather the values of config options which are present
in 'bugreport-config-safelist.h'.
Many config options are sensitive, and many Git add-ons use config
options which git-core does not know about; it is better only to gather
config options which we know to be safe, rather than excluding options
which we know to be unsafe.
Taking the build-time generated array and putting it into a set saves us
time - since git_config_bugreport() is called for every option the user
has configured, performing option lookup in constant time is a useful
optimization.

Occasionally a failure a user is seeing may be related to a specific
hook which is being run, perhaps without the user realizing. While the
contents of hooks can be sensitive - containing user data or process
information specific to the user's organization - simply knowing that a
hook is being run at a certain stage can help us to understand whether
something is going wrong.
Without a definitive list of hook names within the code, we compile our
own list from the documentation. This is likely prone to bitrot. To
reduce the amount of code humans need to read, we turn the list into a
string_list and iterate over it (as we are calling the same find_hook
operation on each string). However, since bugreport should primarily be
called by the user, the performance loss from massaging the string
seems acceptable.

The number of unpacked objects in a user's repository may help us
understand the root of the problem they're seeing, especially if a
command is running unusually slowly.

The refactor removed much of the code Dscho suggested; and yet it
remains true that he helped me while developing this commit (although
his suggestions didn't survive). Shall I leave the Helped-by line or
remove it?

Alongside the loose object counts, it can be useful to show the number
of packs and packed objects. This way we can check whether the repo has
an appropriate ratio of packed to loose objects to help determine
whether it's behaving correctly.

Miscellaneous information used about the object store can end up in
.git/objects/info; this can help us understand what may be going on with
the object store when the user is reporting a bug. Otherwise, it could
be difficult to track down what is going wrong with an object which
isn't kept locally to .git/objects/ or .git/objects/pack. Having some
understanding of where the user's objects may be kept can save us some
hops during the bug reporting process.

In some cases, it could be that the user is having a problem with an
object which isn't present in their normal object directory. We can get
a hint that that might be the case by examining the list of alternates
where their object may be stored instead. Since paths to alternates may
be sensitive, we'll instead count how many alternates have been
specified and note how many of them exist or are broken.
While object-cache.h describes a function "foreach_alt_odb()", this
function does not provide information on broken alternates, which are
skipped over in "link_alt_odb_entry()". Since the goal is to identify
missing alternates, we can gather the contents of
.git/objects/info/alternates manually.

To everyone in the developer community interested in this set: what is
the status of this?
If this needs further review, then maybe it would be best if only
patches 1-4 were put up for submission first, with a note in the
bugreport documentation that more information may be added in future Git
versions. For me, patches 1-4 look good and I don't have enough
experience with uname (especially across libcs and OSes) to determine
what should or should not be included - if this is typical of reviewers
in the Git project, it might be better to submit patches 1-4 first, and
then send each additional diagnostic separately, so that people who know
what's going on in one area but not another can just comment on the area
they know about.
Having said that, I see that a few people have already looked at the
entire patchset and made comments, so if they are OK with it, we don't
need to split it up.

I'd be fine with either; from now, my gut says the only ones I'm not
comfortable merging today are maybe 10, as Junio had some concerns about
whether to allow glob expansion, and 11, as it's prone to rot and I'm
doing other work in that area which would cause 11 to be
dropped/refactored anyways once it goes in. Otherwise I think they're
all pretty OK to go in and let the other work continue later in a
different thread.
Of course, as an author my opinion that they're good to go doesn't mean
much ;)

Should this use `config_scope_name()` which looks like it's about
to graduate [1]? Disclaimer: I haven't followed that patch set too closely.

I would have expected these points to appear later, both to make it
clear what this does commit does (and not), and to highlight what
user-visible (documentation-worthy) changes later commits bring along.

Drop the "[" and "]"? If you give -o, you'd better give a path as well?

"send" sounds like we're *just* about to send this report somewhere, but
it's "only" going to be written to the disk. Maybe "share", instead?

I thought I'd use `-o` to indicate the filename, but it turns out it's
the *directory* where the file (of some semi-random, generated name)
will end up. Re-reading the docs further up, I can see how this is
consistent. I sort of wonder if this should be `--output*-directory*`
for symmetry with `git format-patch`.

Report might be NULL here.
If there's already such a file, we overwrite. Should we generate the
filename using not just today's date (two bug reports in a day wouldn't
be unheard of?) but also something like hh:mm:ss?

Maybe clear the strbuf around here...

... and/or UNLEAK it here, together with report_path.
Maybe "return -launch_editor(...)"?

If foo isn't there, do we not create it? Apparently not -- in my
testing, we segfault. (We don't check for NULL after opening the file.)

Nit: I think this could be patch 01/15. It shuffles things around --
*then*, starting with patch 02/15, we can add exciting stuff.

Hmm, similar nit as for patch 02/15: This could go in as, e.g., 02/15 and
your 01/15 would be 03/15: This patch would be useful even without `git
bugreport`.

The header here looks a lot like an implementation detail of
`get_curl_version_info()`. Or put differently, these risk getting out of
sync. Maybe frame the header a bit more human readable: "curl version".
But is this "curl version", or more like "git-remote-https version"?
There's some discrepancy here.

Thanks for avoiding a classic pitfall. :-)
"<unused>" instead of "(NULL)"? "NULL" is mostly an implementation

I sort of wonder whether safelist/blocklist is to prefer over
whitelist/blacklist, or if it's the other way round. The former are new
to me, whereas the latter are the terms I would have used. But that's
just me, of course. I was a little surprised, that's all.

I recognize this reasoning :-) and I'm not terribly opposed to it, but
after some nights' sleeping on this, I have to wonder if
"annotate:bugreport[include]" wouldn't be better than "bugreport[x]"
with that ugly "x". Maybe this isn't the biggest problem, but if we
expect this macro to eventually sit right next to ~90% of all our config
variables...

That was true in [1], but alas, no more. In that patch, it's sort of
obvious from the diff how it adds a "class" which "end"s.

Haven't looked at this patch at all, except I've noticed that something
is up with the dependencies. I think bugreport.o needs to depend on
bugreport-config-safelist.h. As it is, the latter may or may not be
available as bugreport.o is built. (Reproduces fairly well for me with
something like `make clean && make -j16`.)
I'll try to continue tomorrow. :-)

"which is recognized by" sounds like it's built-in. Maybe "with a new
no-op 'bugreport' macro" or something like that.

Do we really need to list includes *and* excludes? I could see the point
of adding an exclude here and there to signal that "this might look
innocent enough, but trust me, we really need to exclude this" in order
to avoid future commits to more or less accidentally over-include.
Should we add some internal documentation and/or a remark in the commit
message about this? As an example, is "sendemail.signedofcc" sensitive
enough that we need to explicitly exclude it? If someone wants to come
along and include it, they don't just need to argue for an inclusion,
but also for lifting the exclusion. Hmm?

I'm sympathetic to your sending out what you have to obtain comments,
knowing that it's not perfect. It would have saved me some time and
effort if I'd known that this was the case though. An "[RFC]" tag,
perhaps. Or at least tweaking the above part of this commit message to
say that this might be over-engineered, with a reference to [1].

I was going to suggest ARRAY_SIZE, but then I realized there are some
outstanding questions around whether you need this stuff in the first
place. I'd be inclined to guess that the first version of this would be
"for each safelisted item, obtain it and include", ignoring any "a.*.b"
business. In which case you wouldn't really need this hashset stuff.

That's "git help hooks", if I tried my reproduction correctly. A
straight-forward (in the sense of "what we want in the outcome is
quite clear" and not in the sense of "anybody can design and

The design could me just the matter of running "grep" of some sort,

Phrase nit. There may be many people who just enabled hooks without
configuring, so "Enabled Hooks" may be more appropriate. We do not
have to inspect what is in the hook to determine if it is enabled,
but we do need to if we want to tell if a hook is "configured".

You two collectively thought about viable alternatives and decided
to reject what was not wanted in the final result, and not having
that rejected code was good for the project, right? If so, I would
say it still is the help that deserves recognition. After all,
making the result better by removing things is harder than by adding
things ;-)

This lets the enumeration machinery to enumerate at the individual
object level, relies on the enumeration machinery to show your
callback all objects from the same pack before an object from a
different pack, to count both objects and packs.
But given that packfiles record how many objects there are in the
pack, and that the packfile.c layer must know what are the pack
files we have available, I wonder if we have an API already to allow
us to enumerate each packfile, and while counting the number of
times our callback was called, add the objects contained in each of
them. If there isn't, it does not sound like a bad API function to
add (i.e. given a repository r, iterate over r->objects->packed_git
and let the API caller see each of them; the API caller can grab
num_objects and add them up).

This step makes me wonder if we want to see the midx as well.
Didn't we have a bug that manifests only when midx is (or is not) in
use?
Similarly, I think use (or non-use) of the commit graph may also be
a useful information for diagnosing.

Sure. For the sake of brevity I'll probably neglect seconds; I hope
someone is spending more than 1 minute filling in the provided form.
I'm a little worried about including : in a filename, so I went for
'git-bugreport-YYYY-MM-DD-HHMM' (24-hour).
As I started to write a test to ensure duplicate filenames were handled
well, Jonathan Tan pointed out that it would be easy to add an arg like
--suffix to allow specifying a custom strftime string. That would allow
users to easily create a file named
`git-bugreport-fetch-failing.txt` or `git-bugreport-March-19.txt` or
whatever they want; it also makes testing easy. So I'll add this for the
next rollup.

Hm, sure. I see that builtin/tag.c does mark strbufs this way, so I
don't see a problem using UNLEAK and tail-calling launch_editor().
As a final bonus, I also added a line to report to stderr the name of
the file that was created. I noticed it's sort of unclear what the
command actually did otherwise.

Yeah, at the moment I just added a die() if we can't open the provided
path. I think other utilties can create the path (e.g. git-format-patch)
but where it makes sense to do so, I'd prefer to keep bugreport very
simple.
I'll die instead of overwriting, too; you're right that spending quite a
while on a bug report and then accidentally writing over it with a blank
one would be a very bad user experience.

Thanks very much, Martin, for the thorough review. This is incredibly

So it does.
I think the easiest thing is to drop the 'strbuf_reset()' at the top of
help.c:get_version_info(), and just pass in sys_info from bugreport.c.

Hm. I envisioned the target audience for this as "Git developers" (and
that's why I didn't mark the unimplemented string for translation); Git
developers know exactly what "get_compiler_info() not implemented"
means. But I suppose it's just as easy to grep for one string as the
other.
I am hesitant to say "no info available" or "no info reported" when I'm
certain there is some environment variable set at build time which
contains the info we'd want to show here; it really is just a question
of some Git developer having put in the time to implement this function.
So, I think I will leave it. Thanks for your suggestions.

Hm, I think you're saying "If we switch to future-https-lib instead of
cURL for git-remote-https, then this command will be incorrectly named."
Sure, I agree. It's true that with this change git-remote-https also
tells us some info about itself.

This was more of my line of thinking, along with the thought that some
folks may use bug reporting internally, where they have A) more control
over which extensions/tools are in use, and B) less concern about
sharing things like remote URLs, branch names, etc. and may want to go
for a blocklist as opposed to a safelist, to make it easier for their
support folks to diagnose.

Yeah, I think this is a good point. I'll try to figure out how to reword
the commit message, and take another look at the sample include/exclude
change I made to see where I can omit entirely.

Eh. I think the following things are true:
- Whitelist/blacklist has a "smell" of discrimination, whether that's
the true etymology or not.
- Those with experience in the field can easily understand what
whitelist or blacklist means.
- Safelist/blocklist do not "smell" the same way.
- It is easy to tell what "safelist" means: "a list of stuff which is
safe." No experience needed.
So, while it's new, I think it's not harmful. I see only a no-op or
positive impact from using this term instead of whitelist/blacklist.
Computer science seems to have quite a few terms which fall into this
long-standing but potentially negative area, so I don't mind looking for
alternatives where it's harmless to do so.

Hm. I wanted to say, "Ok, but I don't know how to do that, so can you

Ok. I will try and change it to annotate:bugreport[include] like you

Eh. I'm going to try and reword the whole commit message. I combined
your scissors patch, plus something from Dscho's scissors patch, plus my

Hum, I thought that the ordering of the dependency list here was
ensured. But I see where help.o relies directly on command-list.h, so
I'll add a dependency for bugreport.o (and drop it from the direct
dependency for git-bugreport).

Yeah, you are right, and thanks for the feedback. I think I had wrapped
up the series before I realized there were those significant outstanding
comments, but I definitely should have said so in this patch.

Regardless, I think it's worth doing nicely for now.
It seems to me that supporting wildcarding in the config safelist is a
superset of supporting static strings in that safelist - that is, if I
write it simply to support static strings, a later change to support
wildcards would be welcome and non-breaking.
So I'm going to clean this up without making it more featureful, for
now.
Sorry about the confusion!

Well, with Martin's suggestion[1] to use annotate:bugreport[include]
instead of bugreport:include[x], this kind of change becomes a matter of
course to just use "annotate:hook[x]" and write a script nearly
identical to generate-bugreport-config-safelist.sh, and add it to the
Makefile.
Like I said up-thread, I don't like the idea just because it's awfully
temporary (pending work that's right below this on my list for the
coming weeks).
It sounds like you're saying you don't mind any work of this nature
being done as a follow-up - and that's fine with me, too. I'd just
rather do the follow-up with enums and a library than with grep and
sh. :)

Ah, that's a good point. OK, I'll change the wording as you suggested.

Sounds great to me. I'd rather over-assign credit than under-assign (but
I don't think this is a case of over-assigning here).

Sure. I'll look into both of these. Would you rather see them as add-ons
later, or do you want me to hold off on a v6 of this set until they're
ready?

Yeah, I don't see one. I'll go ahead and add it - that sounds

Yeah, agreed. Also, whatever magic the code for gathering the config
items knows, the annotations in Documentation/, i.e., the generated list
in bugreport-config-safelist.h will be "synced". That is, until we know
how to handle "a.*.b" in the safelist, we probably won't be marking
"a.*.b" as safe. And even if we have some crazy mixed build, it's a
*safe*list, so we should be fine. (Famous last words?)
On that topic though, and just so we don't mess up from the beginning,
in the documentation, we typically write something like
"branch.<name>.merge", i.e., not "branch.*.merge". So I guess the
"a.*.b" feature would be more like "look for '.<', something, something,
'>.'." Would that be sufficient? Or would we actually want more
fine-grained control, i.e., something like regexes?
If so, we'd need to provide those regexes somehow, e.g., as part of the
asciidoc macro notation. :-/ Do we need to prepare somehow for such a
future? I don't think we do.

This patchset is based on mr/show-config-scope.
Since v5, I addressed comments from Martin and Junio.
- Reorganized the series so the ecosystem cleanup comes before the
interesting new features.
- Spread out manpage updates to indicate each new feature as it's added.
- Fixed a number of patches which assumed a repo, so bugreport can now
run anywhere.
- Wordsmithing in the report template.
- die() instead of overwriting an existing report.
- Added --suffix to allow user to change the name of the report to
git-bugreport-<strftime format>.txt.
- General NULL-ptr, leak, and bashism cleanup.
- Changed safelist macro from bugreport:include[x] to
annotate:bugreport[include].
- Use git_config_get_value_multi() instead of a config callback to
gather the safelist configs.
- Added a convenience for_each_pack() macro to object-store.h and began
using it in packfile.c and bugreport.c for pack summary

Starting in 3ac68a93fd2, help.o began to depend on builtin/branch.o,
builtin/clean.o, and builtin/config.o. This meant that help.o was
unusable outside of the context of the main Git executable.
To make help.o usable by other commands again, move list_config_help()
into builtin/help.c (where it makes sense to assume other builtin libraries
are present).
When command-list.h is included but a member is not used, we start to
hear a compiler warning. Since the config list is generated in a fairly
different way than the command list, and since commands and config
options are semantically different, move the config list into its own
header and move the generator into its own script and build rule.

It may be useful to know which shell Git was built to try to point to,
in the event that shell-based Git commands are failing. $SHELL_PATH is
set during the build and used to launch the manpage viewer, as well as
by git-compat-util.h, and it's used during tests. 'git version
--build-options' is encouraged for use in bug reports, so it makes sense
to include this information there.

Teach Git how to prompt the user for a good bug report: reproduction
steps, expected behavior, and actual behavior. Later, Git can learn how
to collect some diagnostic information from the repository.
If users can send us a well-written bug report which contains diagnostic
information we would otherwise need to ask the user for, we can reduce
the number of question-and-answer round trips between the reporter and
the Git contributor.
Users may also wish to send a report like this to their local "Git
expert" if they have put their repository into a state they are confused
by.

+================
+
+NAME
+----
+git-bugreport - Collect information for user to file a bug report
+
+SYNOPSIS
+--------
+[verse]
+'git bugreport' [(-o | --output-directory) <path>] [(-s | --suffix) <format>]
+
+DESCRIPTION
+-----------
+Captures information about the user's machine, Git client, and repository state,
+as well as a form requesting information about the behavior the user observed,
+into a single text file which the user can then share, for example to the Git
+mailing list, in order to report an observed bug.
+
+The following information is requested from the user:
+
+ - Reproduction steps
+ - Expected behavior
+ - Actual behavior
+
+OPTIONS
+-------
+-o <path>::
+--output-directory <path>::
+ Place the resulting bug report file in `<path>` instead of the root of
+ the Git repository.
+
+-s <format>::
+--suffix <format>::
+ Specify an alternate suffix for the bugreport name, to create a file
+ named 'git-bugreport-<formatted suffix>'. This should take the form of a
+ link:strftime[3] format string; the current local time will be used.
+
+GIT

Knowing which version of Git a user has and how it was built allows us
to more precisely pin down the circumstances when a certain issue
occurs, so teach bugreport how to tell us the same output as 'git
version --build-options'.
It's not ideal to directly call 'git version --build-options' because
that output goes to stdout. Instead, wrap the version string in a helper
within help.[ch] library, and call that helper from within the bugreport
library.

The contents of uname() can give us some insight into what sort of
system the user is running on, and help us replicate their setup if need
be. The domainname field is not guaranteed to be available, so don't
collect it.

To help pinpoint the source of a regression, it is useful to know some
info about the compiler which the user's Git client was built with. By
adding a generic get_compiler_info() in 'compat/' we can choose which
relevant information to share per compiler; to get started, let's
demonstrate the version of glibc if the user built with 'gcc'.

It's possible for git-remote-curl to be built separately from git; in that
case we want to know what version of cURL is used by git-remote-curl, not
necessarily which version was present at git-bugreport's build time.
So instead, ask git-remote-curl for the version information it knows
about.
Today, "git-remote-http" and "git-remote-https" are aliased to
"git-remote-curl"; but in case we rely on a different library than cURL
in the future, let's not explicitly reference cURL from bugreport.
For longevity purposes, invoke the alias "git-remote-https" instead of
"git-remote-http".
Since it could have been built at a different time, also report the
version and built-from commit of git-remote-curl alongside the cURL info.

It's possible a user may complain about the way that Git interacts with
their interactive shell, e.g. autocompletion or shell prompt. In that
case, it's useful for us to know which shell they're using
interactively.

Add a new step to the build to generate a safelist of git-config
variables which are appropriate to include in the output of
git-bugreport. New variables can be added to the safelist by annotating
their documentation in Documentation/config with the "annotate" macro,
which is a no-op in AsciiDoc and AsciiDoctor.
Some configs are private in nature, and can contain remote URLs,
passwords, or other sensitive information. In the event that a user
doesn't notice their information while reviewing a bugreport, that user
may leak their credentials to other individuals, mailing lists, or bug
tracking tools inadvertently. Heuristic blocklisting of configuration
keys is imperfect and prone to false negatives; given the nature of the
information which can be leaked, a safelist is more reliable.
However, it's possible that in some situations, an organization may be
less concerned with privacy of things like remote URLs and branch names,
and more concerned with ease of diagnosis for their support staff. In
those cases, it may make more sense for that organization to modify the
code to use a blocklist. To that end, we should try to mark configs which
are definitely safe, and configs which are definitely unsafe, and leave
blank configs which are somewhere in between. To mark a config as safe,
add "annotate:bugreport[include]" to the corresponding line in the
config documentation; to mark it as unsafe, add
"annotate:bugreport[exclude]" instead.
Generating bugreport-config-safelist.h at build time by grepping the
documentation for this new macro helps us prevent staleness. The macro
itself is a no-op and should not alter the appearance of the
documentation in either AsciiDoc or AsciiDoctor, confirmable by running:
cd Documentation
./doc-diff --asciidoctor HEAD^ HEAD
./doc-diff --asciidoc HEAD^ HEAD
Diffing the rendered HTML shows that only inline comments were added,
which shouldn't be a problem.
Additionally, add annotations to the sendemail config documentation in
order to demonstrate a proof of concept.

Teach bugreport to gather the values of config options which are present
in 'bugreport-config-safelist.h', and show their origin scope.
Many config options are sensitive, and many Git add-ons use config
options which git-core does not know about; it is better only to gather
config options which we know to be safe, rather than excluding options
which we know to be unsafe.
Rather than including the path to someone's config, which can reveal
filesystem layout and project names, just name the scope (e.g. system,
global, local) of the config source.

Occasionally a failure a user is seeing may be related to a specific
hook which is being run, perhaps without the user realizing. While the
contents of hooks can be sensitive - containing user data or process
information specific to the user's organization - simply knowing that a
hook is being run at a certain stage can help us to understand whether
something is going wrong.
Without a definitive list of hook names within the code, we compile our
own list from the documentation. This is likely prone to bitrot. To
reduce the amount of code humans need to read, we turn the list into a
string_list and iterate over it (as we are calling the same find_hook
operation on each string). However, since bugreport should primarily be
called by the user, the performance loss from massaging the string
seems acceptable.

The number of unpacked objects in a user's repository may help us
understand the root of the problem they're seeing, especially if a
command is running unusually slowly.

Alongside the loose object counts, it can be useful to show the number
of packs and packed objects. This way we can check whether the repo has
an appropriate ratio of packed to loose objects to help determine
whether it's behaving correctly.
Add a utility to easily traverse all packfiles in a given repository.
Use it in packfile.c and remove a redundant call to
prepare_packed_git(), which is already called in get_all_packs().
Signed-off-by: Emily Shaffer <emilyshaffer@google.com>

Perhaps the macro should be in another patch? I didn't spend a lot of
time looking for anybody who could conceivably be iterating packs; if I
were to do so, I'd break this change out separately.
I considered following the pattern in the rest of the file, where the
foreach takes a callback and data pointer, but found it would be
cumbersome to use with for_each_packed_object() - I'd have to add a new
callback just to handle the pack, and bundle that function's callback
data along with the callback pointer. It seemed like overkill.

the object store when the user is reporting a bug. Otherwise, it could
be difficult to track down what is going wrong with an object which
isn't kept locally to .git/objects/ or .git/objects/pack. Having some
understanding of where the user's objects may be kept can save us some
hops during the bug reporting process.

In some cases, it could be that the user is having a problem with an
object which isn't present in their normal object directory. We can get
a hint that that might be the case by examining the list of alternates
where their object may be stored instead. Since paths to alternates may
be sensitive, we'll instead count how many alternates have been
specified and note how many of them exist or are broken.
While object-cache.h describes a function "foreach_alt_odb()", this
function does not provide information on broken alternates, which are
skipped over in "link_alt_odb_entry()". Since the goal is to identify
missing alternates, we can gather the contents of
.git/objects/info/alternates manually.

This while-read-echo was moved from generate-cmdlist.sh,
which has some logic to work with read-variable.
We're moving it out, I think apply this diff on top of it will make the code easier to read.

Is it really necessary to create the directory in advance? Or to put
it in another way: shouldn't 'git bugreport' create any missing
leading directories of the path given for its '-o' option? FWIW, 'git
format-patch -o dir ...' does create all necessary directories.

This breaks the GETTEXT_POISON CI job, because "usage" is translated,
so the test should not look for it with plain 'grep'. Please use
'test_i18ngrep' instead.

GCC 9 complains about this loop condition:

I don't understand this error, that autogenerated
'bugreport_config_safelist' array clearly has a a non-zero size.
What am I missing?

Please add a corresponding entry to 'command-list.txt' as well.
According to the comment at the beginning of that file, all, even
external commands should be included there.

macOS 'sed', that's what I was missing :)
So that array is in fact empty on macOS, because the entries of that
array are generated with:
# cat all regular files in Documentation/config
find Documentation/config -type f -exec cat {} \; |
# print the command name which matches the annotate-bugreport macro
sed -n 's/^\(.*\) \+annotate:bugreport\[include\].* ::$/ "\1",/p' | sort
and the 'sed' included in macOS apparently interprets that '\+'
differently than GNU 'sed', and as a result won't match anything.
FWIW, that '\+' doesn't seem to be necessary, though, and after
removing it the resulting generated array looked good to me (and to
the compiler) both on Linux and macOS.

A reasonable replacement for "<SP>\+" would be "<SP><SP>*" (where <SP>
represents 'space').

Another problem with that regexp is that it contains two adjacent
repetitions matching the same character. When there are two or more
spaces before "annotate:" all but the last of them can be matched by
either '\(.*\)' or ' \+'. To fix that '\(.*\)' needs to be modified to
not match a trailing space.

An often-useful pattern is to make the command report the output
filename, i.e.
REPORT=$(git butreport) &&
if the design insists that "git bugreport" should allocate a
filename in order to make it easy to guarantee uniqueness.
Of course, we can make the invoker supply filename, e.g.
REPORT=$(generate-output-filename) &&
git bugreport -o "$REPORT" ;# or git bugreport >"$REPORT"

Yeah, this is an option and I've changed the offending test - which
captures a variable based on globbing - to use --suffix and force a
filename.

As this topic seems to break under GIT_TEST_GETTEXT_POISON=yes, I'll
apply the following band-aid on top before merging it to 'pu'.
Most of them are style fixes, but quoting $REPORT, not just makes
the redirection honor the coding guidelines, will ensure that an
error is caught if git-bugreport-* glob matches no paths or more
than on paths.

Thanks. Most of these I have locally, but not all. I'll apply this as a
fixup on patch 3/n (the one that introduces the tests) and add a
Helped-by line.
I'm hoping to get a reroll out today; it was the first thing on my list
this week, and then a high-priority internal issue shows up (so it
goes). Sorry for the inconvenience with the CI failures.

Hum. I had assumed since the capture group was not greedy, it would not
capture any trailing spaces that could be captured by ' \+'. I don't see
a problem in making it non-explicit, though.
I'll hack on this some more. I do find myself pretty annoyed at the
matcher difference between 'sed' and 'also sed', though, and don't see
in the manpage a way to guarantee which matcher 'sed' should use (a la
'grep -[EFGP]'). :)

Thanks for the suggestion. You're right that I didn't look into the
contents of this script much, because I was just moving it; I modified
your sed expression slightly so it performs just one operation:
sed 's/^.*$/ "\0",/'

This isn't portable and won't work with 'sed' from BSD lineage,
including Mac OS. More portable would be:
sed 's/^\(.*\)$/ "\1",/'

Done. It passes locally for me now if I run:
USE_ASCIIDOCTOR=1 make doc
Thanks for the heads up.

Or just replace Emily's \0 with &; that should be in POSIX.

Yes, that's nicer.

This patchset is based on mr/show-config-scope, which looks close to
ready for 'next'.
Since v6:
- Applied Danh's suggestion[1] (with modifications recommended by Eric and
Junio downthread)
- Fixed a missed end-of-macro in the Asciidoctor config which was
pointed out most recently by SZEDER[2]
- Fixed generate-bugreport-safelist-config.sh to be more friendly to
BSD-derived 'sed' and to capture trailing ' ' when extra whitespace is
present(patch 9/15). This now uses POSIX character classes and {}
notation instead of + and has been tested on OSX; I'd love to hear if
it's still not working correctly.
- Applied Junio's patch[3] to make GIT_TEST_GETTEXT_POISON happy and to
make the tests more idiomatic.
- Stop globbing into variables, start making the output directory if it
doesn't exist before[4]
- Add an entry in 'command-list.txt'[5]. I sure wish someone had
explained how to do this somewhere in a tutorial about writing new
commands ;)
- Added a test to ensure that git-bugreport runs gracefully in a
non-repo directory.
- Added nongit_ok flags to relevant pieces of info to ensure the above
test passes.

Starting in 3ac68a93fd2, help.o began to depend on builtin/branch.o,
builtin/clean.o, and builtin/config.o. This meant that help.o was
unusable outside of the context of the main Git executable.
To make help.o usable by other commands again, move list_config_help()
into builtin/help.c (where it makes sense to assume other builtin libraries
are present).
When command-list.h is included but a member is not used, we start to
hear a compiler warning. Since the config list is generated in a fairly
different way than the command list, and since commands and config
options are semantically different, move the config list into its own
header and move the generator into its own script and build rule.

It may be useful to know which shell Git was built to try to point to,
in the event that shell-based Git commands are failing. $SHELL_PATH is
set during the build and used to launch the manpage viewer, as well as
by git-compat-util.h, and it's used during tests. 'git version
--build-options' is encouraged for use in bug reports, so it makes sense
to include this information there.

Teach Git how to prompt the user for a good bug report: reproduction
steps, expected behavior, and actual behavior. Later, Git can learn how
to collect some diagnostic information from the repository.
If users can send us a well-written bug report which contains diagnostic
information we would otherwise need to ask the user for, we can reduce
the number of question-and-answer round trips between the reporter and
the Git contributor.
Users may also wish to send a report like this to their local "Git
expert" if they have put their repository into a state they are confused
by.

+================
+
+NAME
+----
+git-bugreport - Collect information for user to file a bug report
+
+SYNOPSIS
+--------
+[verse]
+'git bugreport' [(-o | --output-directory) <path>] [(-s | --suffix) <format>]
+
+DESCRIPTION
+-----------
+Captures information about the user's machine, Git client, and repository state,
+as well as a form requesting information about the behavior the user observed,
+into a single text file which the user can then share, for example to the Git
+mailing list, in order to report an observed bug.
+
+The following information is requested from the user:
+
+ - Reproduction steps
+ - Expected behavior
+ - Actual behavior
+
+OPTIONS
+-------
+-o <path>::
+--output-directory <path>::
+ Place the resulting bug report file in `<path>` instead of the root of
+ the Git repository.
+
+-s <format>::
+--suffix <format>::
+ Specify an alternate suffix for the bugreport name, to create a file
+ named 'git-bugreport-<formatted suffix>'. This should take the form of a
+ link:strftime[3] format string; the current local time will be used.
+
+GIT

+Part of the linkgit:git[1] suite

Knowing which version of Git a user has and how it was built allows us
to more precisely pin down the circumstances when a certain issue
occurs, so teach bugreport how to tell us the same output as 'git
version --build-options'.
It's not ideal to directly call 'git version --build-options' because
that output goes to stdout. Instead, wrap the version string in a helper
within help.[ch] library, and call that helper from within the bugreport
library.

The contents of uname() can give us some insight into what sort of
system the user is running on, and help us replicate their setup if need
be. The domainname field is not guaranteed to be available, so don't
collect it.

To help pinpoint the source of a regression, it is useful to know some
info about the compiler which the user's Git client was built with. By
adding a generic get_compiler_info() in 'compat/' we can choose which
relevant information to share per compiler; to get started, let's
demonstrate the version of glibc if the user built with 'gcc'.

It's possible for git-remote-curl to be built separately from git; in that
case we want to know what version of cURL is used by git-remote-curl, not
necessarily which version was present at git-bugreport's build time.
So instead, ask git-remote-curl for the version information it knows
about.
Today, "git-remote-http" and "git-remote-https" are aliased to
"git-remote-curl"; but in case we rely on a different library than cURL
in the future, let's not explicitly reference cURL from bugreport.
For longevity purposes, invoke the alias "git-remote-https" instead of
"git-remote-http".
Since it could have been built at a different time, also report the
version and built-from commit of git-remote-curl alongside the cURL info.

It's possible a user may complain about the way that Git interacts with
their interactive shell, e.g. autocompletion or shell prompt. In that
case, it's useful for us to know which shell they're using
interactively.

Add a new step to the build to generate a safelist of git-config
variables which are appropriate to include in the output of
git-bugreport. New variables can be added to the safelist by annotating
their documentation in Documentation/config with the "annotate" macro,
which is a no-op in AsciiDoc and AsciiDoctor.
Some configs are private in nature, and can contain remote URLs,
passwords, or other sensitive information. In the event that a user
doesn't notice their information while reviewing a bugreport, that user
may leak their credentials to other individuals, mailing lists, or bug
tracking tools inadvertently. Heuristic blocklisting of configuration
keys is imperfect and prone to false negatives; given the nature of the
information which can be leaked, a safelist is more reliable.
However, it's possible that in some situations, an organization may be
less concerned with privacy of things like remote URLs and branch names,
and more concerned with ease of diagnosis for their support staff. In
those cases, it may make more sense for that organization to modify the
code to use a blocklist. To that end, we should try to mark configs which
are definitely safe, and configs which are definitely unsafe, and leave
blank configs which are somewhere in between. To mark a config as safe,
add "annotate:bugreport[include]" to the corresponding line in the
config documentation; to mark it as unsafe, add
"annotate:bugreport[exclude]" instead.
Generating bugreport-config-safelist.h at build time by grepping the
documentation for this new macro helps us prevent staleness. The macro
itself is a no-op and should not alter the appearance of the
documentation in either AsciiDoc or AsciiDoctor, confirmable by running:
cd Documentation
./doc-diff --asciidoctor HEAD^ HEAD
./doc-diff --asciidoc HEAD^ HEAD
Diffing the rendered HTML shows that only inline comments were added,
which shouldn't be a problem.
Additionally, add annotations to the sendemail config documentation in
order to demonstrate a proof of concept.

Teach bugreport to gather the values of config options which are present
in 'bugreport-config-safelist.h', and show their origin scope.
Many config options are sensitive, and many Git add-ons use config
options which git-core does not know about; it is better only to gather
config options which we know to be safe, rather than excluding options
which we know to be unsafe.
Rather than including the path to someone's config, which can reveal
filesystem layout and project names, just name the scope (e.g. system,
global, local) of the config source.

Occasionally a failure a user is seeing may be related to a specific
hook which is being run, perhaps without the user realizing. While the
contents of hooks can be sensitive - containing user data or process
information specific to the user's organization - simply knowing that a
hook is being run at a certain stage can help us to understand whether
something is going wrong.
Without a definitive list of hook names within the code, we compile our
own list from the documentation. This is likely prone to bitrot. To
reduce the amount of code humans need to read, we turn the list into a
string_list and iterate over it (as we are calling the same find_hook
operation on each string). However, since bugreport should primarily be
called by the user, the performance loss from massaging the string
seems acceptable.

The number of unpacked objects in a user's repository may help us
understand the root of the problem they're seeing, especially if a
command is running unusually slowly.

Alongside the loose object counts, it can be useful to show the number
of packs and packed objects. This way we can check whether the repo has
an appropriate ratio of packed to loose objects to help determine
whether it's behaving correctly.
Add a utility to easily traverse all packfiles in a given repository.
Use it in packfile.c and remove a redundant call to
prepare_packed_git(), which is already called in get_all_packs().

Miscellaneous information used about the object store can end up in
.git/objects/info; this can help us understand what may be going on with
the object store when the user is reporting a bug. Otherwise, it could
be difficult to track down what is going wrong with an object which
isn't kept locally to .git/objects/ or .git/objects/pack. Having some
understanding of where the user's objects may be kept can save us some
hops during the bug reporting process.

In some cases, it could be that the user is having a problem with an
object which isn't present in their normal object directory. We can get
a hint that that might be the case by examining the list of alternates
where their object may be stored instead. Since paths to alternates may
be sensitive, we'll instead count how many alternates have been
specified and note how many of them exist or are broken.
While object-cache.h describes a function "foreach_alt_odb()", this
function does not provide information on broken alternates, which are
skipped over in "link_alt_odb_entry()". Since the goal is to identify
missing alternates, we can gather the contents of
.git/objects/info/alternates manually.

This step seems to have a new whitespace breakage that did not exist
in the previous round.

This helper is about creating paths in the working tree and Git
repository, hence it has a call to adjust_shared_perm() which in
turn calls get_shared_repo(), i.e. requiring a repository.
I thought I read somewhere that this tool is meant to be usable
outside a repository? If that is not the case, then the use of this
helper is OK. If not, we may want to make sure that it will stay to
be safe to use the helper (I think it happens to be OK right now,
but if the reason why the user is trying to run the tool is because
the user broke Git by writing garbage into .git/config, we may
die("your configuration file is broken") before this helper returns).
Thanks.

I'd rather not to see unnecessary uses of POSIX character classes.
The interdiff of this step between the previous and this round looks
to me more like "I used it, just because POSIX says I *can* use it",
not "I did so because I needed to do, and it should be OK on POSIX
platforms."
Instead of overly long
's/^\([^[:blank:]]*\)[[:blank:]]\{1,\}annotate:bugreport\[include\].* ::$/ "\1",/p'
just limiting ourselves to SP and saying
's/^\([^ ]*\) *annotate:bugreport\[include\].* ::$/ "\1",/p'
would keep the result much easier to read, I would think.

That's fine by me. I find the [[:syntax:]] extremely ugly, but I was
worried about whether that was more portable somehow. Your proposal
seems fine to me.

It's also used by cmd_format_patch() with --output-directory specified,
which is how I found it. My usual workflow is to run format-patch with
-o ~/mailed-patches/topic/ specified so I don't clutter my repo, so I'm
surprised to hear the intent of safe_create_leading_directores() is for
paths in the working tree or repo.

Hmmm. I was able to run it pretty happily from a nongit dir:
emilyshaffer@podkayne:~$ tg bugreport -o other/very/deep/path/
Created new report at 'other/very/deep/path/git-bugreport-2020-02-14-1721.txt'.
emilyshaffer@podkayne:~$ cat other/very/deep/path/git-bugreport-2020-02-14-1721.txt
Thank you for filling out a Git bug report!

Can you explain a little more about what you mean? A broken local
.git/config seems to be preventing git.c from dispatching the
'bugreport' subcommand (lots of other Git commands are broken) at all -
breakpoints in cmd_main() right after the variable declarations are not
being hit.
With junk in the .git/config, I can't run bugreport from within that
repo. With junk in ~/.gitconfig, I can't run bugreport anywhere.
(To make the configs invalid, I leaned on my keyboard and added a line
'garbaghe~*~$%)%)(@' to the bottom of the config file. Most commands
terminate early with "fatal: bad config line 37 in file .git/config".)
Do you mean there's some specific config that could be misconfigured and
prevent that utility from working?

And that is an example of a good use of this helper. What will be
written out there should be visible by the same people as those who
have access to the repository; get_shared_repo() and adjust_perm()
based on what the repository you are taking patches from is
perfectly sensible. And as it is format-patch, we know we have
get_shared_repo() working, and we know which repository we are
working on.
Output directory for bugreport is on the same boat when we know the
users are producing a report on their use of Git within a
repository. It is not clear if the tool is started without any
repository---it happens to do a random safe thing (i.e. I think
get_shared_repo() gives PERM_UMASK, which tells adjust_perm() not to
do anything especial) right now, but there is no guarantee that we
will keep it working like that. Somebody may come and demaind
get_shared_perm() to die() when outside a repository, for example,
and that would break the nice property that lets bugreport working
outside a repository.
I just wanted to make sure that somebody will be keeping an eye to
remind those who propose such a change in the future. A comment
near where get_shared_repo() happens may be something that can be
done with a minimum effort when code that depends on that property
is introduced at the same time.

I am actually OK if we limit the use of this tool to "use with a
repository that is not corrupt", as coping with these kinds of
breakages that in the main Git executable we deem "needs manual
intervention" inside a single process is too painful (it would have
been easier to cope with these too if we stuck with a script that
invokes many discrete commands and acts on their errors, but that is
optimizing for rare case and not recommended). But we should tell
users about the limitation and encourage them to ask for help in non
automatable means.
Thanks.

Hm, this would break the convention of the name of
safe_create_leading_directories() too though right? As I understood it,
"safe_foo" in this codebase means "this function will not die()"?

Ok. I want to make sure I understand you right. I think you're saying,
"This is OK, except if someone changes get_shared_repo() it could break,
so we need a way to warn someone that it could break." It sounds like
you suggested leaving a comment in the
safe_create_leading_directories() helper. My own preference is to write
a test so that it's explicit that we depend on that behavior, instead -
it's easy to gloss over a comment or read a different part of the
codebase, but it's hard to ignore a breaking test. It'd be trivial to
add one, so I will in v8 - unless I misunderstood you.

I think you're saying, "Mention this drawback in the manpage for
git-bugreport." Sounds like a good idea to me, so I'll add it for v8.

I'm pretty unsure about how you wanted this to sound; rather than
sending a v8 only to revise it a lot, I'll send the paragraph for
wordsmithing beforehand. Is this what you meant?
This tool is invoked via the typical Git setup process, which means that in some
cases, it might not be able to launch - for example, if a relevant config file
is unreadable. In this kind of scenario, it may be helpful to manually gather
the kind of information listed above when manually asking for help.

Hmph. I saw it warned at some point during the rebase-and-format-patch
workflow for v7 but thought I had quashed it. Very sorry.

This would be the first time (at least that _I_ know of) that we use `-`
in this way. We seem to use `!!` a lot more often. And now I wonder
whether there is a reason for that `-` that I missed?

I agree with the need for the compiler information, but in the patch I
only see information about glibc being printed out. Shouldn't we use
`__GNUC__` and `__GNUC_MINOR__` here?
Don't get me wrong, the glibc version is good and all, but the compiler
information might be even more crucial. Git for Windows had to hold back
compiling with GCC v8.x for a while, for example, because the stacksmasher
was broken. Similar issues are not unheard of, and could help pinpoint
compiler-related problems a lot quicker.

Let's use RUN_GIT_CMD instead of adding `"git"` explicitly; It documents
that we're interested in a Git command, and if we ever build a
single-binary version of Git (as some Git for Windows users already asked
for), it will make things easier.

The context does not say this, but at this point, we already verified that
`argc` is larger than 1. Good.
Also, in keeping with the existing code, we would need to use
`--build-options` here (this is what `git version` calls the equivalent
mode).
_However_.
I like your `--build-info` a lot more than `--build-options` (because the
latter is very misleading: the commit and the date of the build are not
"options" at all).

In general, our preferred way to report an error from API functions
is to return a negative number and a success is reported by
returning zero.
The argument to exit(3), which the return value from the main()
function essentially is, on the other hand, is expected to be a
small non-negative integer. As long as we are in tight control of
the range of the returned value from launch_editor() (i.e. it must
return a small non-positive integer whose negation is suitable to be
fed to exit(3)), the above is fine.
The idiom "return !!fn();" is to canonicalize the value to 0 or 1
for the caller who asked "so, did fn() give us 0 or non-zero?",
which can also be used as the value given to exit(3), and could be
more appropriate under some conditions:
- we MUST know launch_editor() returns zero if and only if it is
successful.
- we do not have to be confident to be in tight control of the
range of the returned value from launch_editor() (e.g. it could
return a positive upon an error).
- we MUST NOT care to differenciate different error codes returned
from launch_editor(). IOW, we must be fine to give the invoker
of the program only 0 (success) or 1 (unspecified failure).
Use of "return !!fn();" that is not to give to exit(3) is probably
more common in our codebase. See apply.c::try_create_file() and the
comment before the function about its possible return values for
example.

In editor.c, launch_editor() returns launch_specified_editor() without
altering the return code.

launch_specified_editor() has a handful of exit points, of three kinds:
1. return error(something)
2. raise(sigsomething)
3. return 0
a. when the editor process closed happily, but the user supplied
NULL instead of a buffer. That is, the user didn't want the
contents of the editor given back to them in a strbuf.
b. when the editor process closed happily and the user's supplied
buffer was filled with the file's contents with no issue.
So I think we can check "yes" here.

According to 'man 3 raise' (POSIX), raise() exits the current thread. If it
can't exit itself(?) it seems it returns "nonzero for failure". We've
also got a mingw_raise() in compat/mingw.h which could be used instead;
this one seems to return -1 or the result of raise(), presumably the one
from the MSC runtime[1], which also returns "a nonzero value" if not
successful.
So it's true that we aren't confident that launch_editor() returns a
positive or negative value.

This part is a little sticking point for me; I think I'd rather give the
user some hint of what's broken than no hint at all, especially in this
scenario, where it's conceivable someone could say "I tried to run
'git-bugreport' and it crashed, here is the return code and I have
manually collected some relevant info too".
The uncertainty coming from raise() (POSIX and MSCR both) leads me to
believe if I do want to return the error on exit, I should at least
check the sign before I flip it. Anybody else have opinions?

Heh. If we raised a signal to kill ourselves, then we won't be
returning a value from launch_editor() anyway. That case won't
affect the "between returning negation or !!, which is more
appropriate?" discussion, I think.
>> - we MUST NOT care to differenciate different error codes returned

I actually think this holds for the codepath. A failure from
start_command() returns error(), and finish_command() that waits for
the spawned editor process to complete yields the exit status from
the editor, but unless we re-raise the signal that killed the editor
process to ourselves, we just turn any non-zero exit into "return
error()", so it is safe to say launch_editor() can return either 0
or -1 and nothing else. Would we later want to tell callers of
launch_editor() how/why the editor session failed by returning
something else? I do not offhand think of any---we do not even
differenciate between failure to start (e.g. misspelt command name
for the editor) and other failures WITH the return value and
consider it sufficient to tell the user with different error
message right now.
So in practice returning -launch_editor() and !!launch_editor()
would not make any difference, I would think.

Hm. RUN_GIT_CMD is an argument used for the run_command_v_opt* family of
calls, but it seems that setting child_process.git_cmd has the same
effect. Done.

I don't think anybody would mind introducing --build-info to "git
version" as a synonym and deprecate --build-options from it ;-)

Hm, sure. Good point - thanks.
This does make me start to wonder, though - does it really make sense to
have ifdef-gated redefinitions of the whole get_compiler_info() method
like I do now? I wonder if it makes more sense to have only one
definition, so we can write down everything we know regardless of which
pieces are put together. My thinking is something like this - what if I
am using glibc, but not a GNU compiler? (The GNU docs on __GCC__
indicate this is a situation that might occur - "a non-GCC compiler that
claims to accept the GNU C dialects") Is there some striking reason not
to implement this compat command thusly instead:
#ifdef __GLIBC__
#include <gnu/libc-version.h>
#endif
static inline void get_compiler_info(struct strbuf *info)
{
#ifdef __GLIBC__
strbuf_addf(info, "glibc: %s\n", gnu_get_libc_version());
#endif
#ifdef __GNUC__
strbuf_addf(info, "gnuc: %d.%d\n", __GNUC__, __GNUC_MINOR__);
#endif
#ifdef _MSC_VER
strbuf_addf(info, "msc runtime: %s\n", some_msc_info());
#endif
}
The thinking being - this way if I decide to use, say, LLVM + glibc,
then I don't need to reimplement this command with all the glibc
diagnostics again. Or, if someone else already wrote diagnostics for
LLVM with some other libc, then it even Just Works for me and my new
combination.
That said, I'm reasoning about these combinations of compilers and libcs
and whatever else from an inexperienced viewpoint, so maybe this isn't
necessary?

Then, let's do the least surprising thing. I'll switch it to !! for the

Since I saw lots of replies from Junio elsewhere in this thread, I'll
take the silence here as assent. v8 on its way momentarily.

Heh, it's just I have too little time to allocate on this single
topic X-<. Don't take silence as anything else.

No longer relies on any topic branches, since mr/show-config-scope is
merged. Range-diff at the bottom of the cover letter.
Since v7:
- Dropped some POSIX regex magic in
generate-bugreport-config-safelist.sh.
- Added some advice in doc for scenarios when git-bugreport may not run
nicely
- Quit using unusual "return -foo(bar)" and start using "return
!!foo(bar)"
- Add a test to ensure path creation works outside of a git dir
- Add some GNUC and GNUC_MINOR reporting
- Use git_cmd instead of hardcoding "git" as the first arg when
invoking another process
- Fix some pesky whitespace
Thanks.

Starting in 3ac68a93fd2, help.o began to depend on builtin/branch.o,
builtin/clean.o, and builtin/config.o. This meant that help.o was
unusable outside of the context of the main Git executable.
To make help.o usable by other commands again, move list_config_help()
into builtin/help.c (where it makes sense to assume other builtin libraries
are present).
When command-list.h is included but a member is not used, we start to
hear a compiler warning. Since the config list is generated in a fairly
different way than the command list, and since commands and config
options are semantically different, move the config list into its own
header and move the generator into its own script and build rule.
