[PATCH 00/10] Pulling signed tag

[PATCH 00/10] Pulling signed tag

[Junio C Hamano]

This is my fourth iteration to solve the "how can we allow authenticity of
work by contributors to be validated by the integrator and leave enough
information for later audit by third parties" topic. What is unusual is
that this is not a fourth re-roll of one approach re-re-re-polished, but
these four are all based on different design.

This round is based on Linus's "let the integrator pull signed tag from
the contributor" design.

The first patch is the same as the one at the bottom of the third
iteration which was jc/signed-commit topic. The rest are new.

 1. Split GPG interface into its own helper library

 2. fetch: do not store peeled tag object names in FETCH_HEAD
 3. merge: notice local merging of tags and keep it unwrapped
 4. fetch: allow "git fetch $there v1.0" to fetch a tag
 5. tests: distinguish merges of tags and commits

"git fetch" used to peel tags too early when storing in FETCH_HEAD (the
input to fmt-merge-msg), and "git merge" did the same when internally
preparing the list of what are merged to feed the internal fmt-merge-msg.

The above four stops doing so, whose effect can be seen in the changes to
the test vector in the fifth patch.

 6. refs DWIMmery: use the same rule for both "git fetch" and others

You can pull a tag with "git pull $there tags/for-linus", but this allows
you to say "git pull $there for-linus".

 7. fmt-merge-msg: avoid early returns
 8. fmt-merge-msg: package options into a structure
 9. fmt-merge-msg: Add contents of merged tag in the merge message

The first two of this segment are small clean-ups to make the third one
possible. When merging signed tag(s), the merge message is prepared with
the contents of the tag object for later independent audit at the end, and
also contains the output from the GPG verification process as the comment
to help the integrator verify it.

10. merge: force edit mode when merging a tag object

And in order to _show_ that comment, we would need to show it in the
editor before the commit happens, hence this conclusion patch.

[PATCH 01/10] Split GPG interface into its own helper library

[Junio C Hamano]

This mostly moves existing code from builtin/tag.c (for signing)
and builtin/verify-tag.c (for verifying) to a new gpg-interface.c
file to provide a more generic library interface.

 - sign_buffer() takes a payload strbuf, a signature strbuf, and a signing
   key, runs "gpg" to produce a detached signature for the payload, and
   appends it to the signature strbuf. The contents of a signed tag that
   concatenates the payload and the detached signature can be produced by
   giving the same strbuf as payload and signature strbuf.

 - verify_signed_buffer() takes a payload and a detached signature as
   <ptr, len> pairs, and runs "gpg --verify" to see if the payload matches
   the signature. It can optionally capture the output from GPG to allow
   the callers to pretty-print it in a way more suitable for their
   contexts.

"verify-tag" (aka "tag -v") used to save the whole tag contents as if it
is a detached signature, and fed gpg the payload part of the tag. It
relied on gpg to fail when the given tag is not signed but just is
annotated.  The updated run_gpg_verify() function detects the lack of
detached signature in the input, and errors out without bothering "gpg".

[PATCH 02/10] fetch: do not store peeled tag object names in FETCH_HEAD

[Junio C Hamano]

From: Linus Torvalds <torvalds@linux-foundation.org>

From: Linus Torvalds <torvalds@linux-foundation.org>

We do not want to record tags as parents of a merge when the user does
"git pull $there tag v1.0" to merge tagged commit, but that is not a good
enough excuse to peel the tag down to commit when storing in FETCH_HEAD.
The caller of underlying "git fetch $there tag v1.0" may have other uses
of information contained in v1.0 tag in mind.

[jc: the test adjustment is to update for the new expectation]

You can already do so with "git fetch $there tags/v1.0" but if it is not

Recent merge can distinguish merging of local tags from commits,

[PATCH 06/10] refs DWIMmery: use the same rule for both "git fetch" and others

[Junio C Hamano]

"git log frotz" can DWIM to "refs/remotes/frotz/HEAD", but in the remote
access context, "git fetch frotz" to fetch what the other side happened to
have fetched from what it calls 'frotz' (which may not have any relation
to what we consider is 'frotz') the last time would not make much sense,
so the fetch rules table did not include "refs/remotes/%.*s/HEAD".

When the user really wants to, "git fetch $there remotes/frotz/HEAD" would
let her do so anyway, so this is not about safety or security; it merely
is about confusion avoidance and discouraging meaningless usage.

Specifically, it is _not_ about ambiguity avoidance. A name that would
become ambiguous if we use the same rules table for both fetch and local
rev-parse would be ambiguous locally at the remote side.

So for the same reason as we added rule to allow "git fetch $there v1.0"
instead of "git fetch $there tags/v1.0" in the previous commit, here is a
bit longer rope for the users, which incidentally simplifies our code.

[PATCH 07/10] fmt-merge-msg: avoid early returns

In various places in the codepath, the program tries to return early
assuming there is no more work needed. That is generally untrue when
over time new features are added.

[PATCH 09/10] fmt-merge-msg: Add contents of merged tag in the merge message

[Junio C Hamano]

When a contributor asks the integrator to merge her history, a signed tag
can be a good vehicle to communicate the authenticity of the request while
conveying other information such as the purpose of the topic.

E.g. a signed tag "for-linus" can be created, and the integrator can run:

   $ git pull git://example.com/work.git/ for-linus

This would allow the integrator to run "git verify-tag FETCH_HEAD" to
validate the signed tag.

While we do not necessarily want to clutter the global tag namespace of
the project, we would want to leave enough information in the repository
to allow third party to later validate the resulting history.

Update fmt-merge-msg that prepares the merge message template, and store
the contents of the signed tag object and the message that comes from GPG
signature validation at the end of it. The integrator can choose to leave
the contents of the tag in the resulting merge commit, or can choose to
remove it. The GPG validation message is inserted as a comment only to
help the integrator to review the validation result but otherwise will not
be recorded in the resulting merge commit, because later validation by
third parties does not need it.

Since the tag signature depends on the tag message, including all spelin
errors, the integrator must not change the text so that third parties
can repeat the verification. (Correct?) I assume this is the reason that
you put 'tag:' in front of the tag message, to discourage any changes.

What if the tag is not signed? Does this code path trigger at all? In
this case, I would prefer that the discouraging 'tag:' prefix were not
present. The resulting text would fit more naturally in a commit message
as a description of the commit/merge/topic. What do you think?

Yes, but after reading response from Linus in the other thread, I think we
came up with even a better plan.

That thread is really long and I may have missed pieces here and
there. My understanding is that this topic now, while supports kernel
development model, would not address the problem gentoo has, which is
described by Robbin in the same thread [1]. Is that correct?

[PATCH v2 00/12] Pulling signed/annotated tags

[Junio C Hamano]

This is a re-roll of the fourth iteration.

  Split GPG interface into its own helper library
  fetch: do not store peeled tag object names in FETCH_HEAD
  merge: notice local merging of tags and keep it unwrapped
  fetch: allow "git fetch $there v1.0" to fetch a tag
  refs DWIMmery: use the same rule for both "git fetch" and others
  fmt-merge-msg: avoid early returns
  fmt-merge-msg: package options into a structure

The above are unchanged from v1, except for the test patch that is
gone. It has been merged into the patch that changes the behaviour to
require the adjustment to the test.

  fmt-merge-msg: Add contents of merged tag in the merge message

This is updated to not show the ugly tag contents with "tag:" prefix in
the merge log editor. Instead, the body of the tag (excluding the
signature if it is a signed tag) is given without any prefix to help the
integrator write a better log message. This happens even when merging an
annotated (not signed) tag.

  merge: make usage of commit->util more extensible
  merge: record tag objects without peeling in MERGE_HEAD
  commit: copy merged signed tags to headers of merge commit

These three are new and are necessary to copy "cat-file tag" of a signed
tag to the header of resulting merge commit.

  merge: force edit mode when merging a tag object

The implementation of this one has changed, but the spirit hasn't.

[PATCH v2 01/12] Split GPG interface into its own helper library

[Junio C Hamano]

This mostly moves existing code from builtin/tag.c (for signing)
and builtin/verify-tag.c (for verifying) to a new gpg-interface.c
file to provide a more generic library interface.

 - sign_buffer() takes a payload strbuf, a signature strbuf, and a signing
   key, runs "gpg" to produce a detached signature for the payload, and
   appends it to the signature strbuf. The contents of a signed tag that
   concatenates the payload and the detached signature can be produced by
   giving the same strbuf as payload and signature strbuf.

 - verify_signed_buffer() takes a payload and a detached signature as
   <ptr, len> pairs, and runs "gpg --verify" to see if the payload matches
   the signature. It can optionally capture the output from GPG to allow
   the callers to pretty-print it in a way more suitable for their
   contexts.

"verify-tag" (aka "tag -v") used to save the whole tag contents as if it
is a detached signature, and fed gpg the payload part of the tag. It
relied on gpg to fail when the given tag is not signed but just is
annotated.  The updated run_gpg_verify() function detects the lack of
detached signature in the input, and errors out without bothering "gpg".

[PATCH v2 02/12] fetch: do not store peeled tag object names in FETCH_HEAD

[Junio C Hamano]

From: Linus Torvalds <torvalds@linux-foundation.org>

We do not want to record tags as parents of a merge when the user does
"git pull $there tag v1.0" to merge tagged commit, but that is not a good
enough excuse to peel the tag down to commit when storing in FETCH_HEAD.
The caller of underlying "git fetch $there tag v1.0" may have other uses
of information contained in v1.0 tag in mind.

[jc: the test adjustment is to update for the new expectation]

[PATCH v2 03/12] merge: notice local merging of tags and keep it unwrapped

[Junio C Hamano]

This also updates the autogenerated merge title message from "merge commit X"
to "merge tag X", and its effect can be seen in the changes to the test suite.

[PATCH v2 04/12] fetch: allow "git fetch $there v1.0" to fetch a tag

[Junio C Hamano]

You can already do so with "git fetch $there tags/v1.0" but if it is not
ambiguous there is no reason to force users to type more.

[PATCH v2 05/12] refs DWIMmery: use the same rule for both "git fetch" and others

[Junio C Hamano]

"git log frotz" can DWIM to "refs/remotes/frotz/HEAD", but in the remote
access context, "git fetch frotz" to fetch what the other side happened to
have fetched from what it calls 'frotz' (which may not have any relation
to what we consider is 'frotz') the last time would not make much sense,
so the fetch rules table did not include "refs/remotes/%.*s/HEAD".

When the user really wants to, "git fetch $there remotes/frotz/HEAD" would
let her do so anyway, so this is not about safety or security; it merely
is about confusion avoidance and discouraging meaningless usage.

Specifically, it is _not_ about ambiguity avoidance. A name that would
become ambiguous if we use the same rules table for both fetch and local
rev-parse would be ambiguous locally at the remote side.

So for the same reason as we added rule to allow "git fetch $there v1.0"
instead of "git fetch $there tags/v1.0" in the previous commit, here is a
bit longer rope for the users, which incidentally simplifies our code.

[PATCH v2 06/12] fmt-merge-msg: avoid early returns

In various places in the codepath, the program tries to return early
assuming there is no more work needed. That is generally untrue when
over time new features are added.

[PATCH v2 08/12] fmt-merge-msg: Add contents of merged tag in the merge message

[Junio C Hamano]

When a contributor asks the integrator to merge her history, a signed tag
can be a good vehicle to communicate the authenticity of the request while
conveying other information such as the purpose of the topic.

E.g. a signed tag "for-linus" can be created, and the integrator can run:

   $ git pull git://example.com/work.git/ for-linus

This would allow the integrator to run "git verify-tag FETCH_HEAD" to
validate the signed tag.

Update fmt-merge-msg so that it pre-fills the merge message template with
the body (but not signature) of the tag object to help the integrator write
a better merge message, in the same spirit as the existing merge.log summary
lines.

The message that comes from GPG signature validation is also included in
the merge message template to help the integrator verify it, but they are
prefixed with "#" to make them comments.

[PATCH v2 09/12] merge: make usage of commit->util more extensible

[Junio C Hamano]

The merge-recursive code uses the commit->util field directly to annotate
the commit objects given from the command line, i.e. the remote heads to
be merged, with a single string to be used to describe it in its trace
messages and conflict markers.

Correct this short-signtedness by redefining the field to be a pointer to
a structure "struct merge_remote_desc" that later enhancements can add
more information. Store the original objects we were told to merge in a
field "obj" in this struct, so that we can recover the tag we were told to
merge.

middle of merging an annotated or signed tag, not a plain commit, after
"git merge" stops to ask the user to resolve conflicts.

[PATCH v2 11/12] commit: copy merged signed tags to headers of merge commit

[Junio C Hamano]

Now MERGE_HEAD records the tag objects without peeling, we could record
the result of manual conflict resolution via "git commit" without losing
the tag information.

In hindsight, it would have been better to make "merge --continue" as the
way to continue from such an interrupted merge, not "commit", but this is
a backward compatibility baggage we would need to carry around for now.

[PATCH v2 12/12] merge: force edit mode when merging a tag object

[Junio C Hamano]

Now that we allow pulling a tag from the remote site to validate the
authenticity, we should give the user the final chance to verify and
edit the merge message.

Ok, this all looks fine to me.

Clean series, and everything looks fine.

The one thing I wondered about is what happens when you merge two
signed tags. Maybe I read the patch wrong, but it *looks* to me like
the code just appends them all together with nothing in between. Is it
still parseable?

I guess I could just try it out .. ;)

Eek.

The mergetag stuff is a dump of "cat-file tag" so if you have a line that
begins with "object " the parsing side (which does not exist yet) would
have trouble. We would need to devise e.g. adding number of lines at the
beginning, or something.

Might I suggest making it simpler still to parse?

Change "strbuf_add_lines()" to have two *different* prefixes: one for
the first line, and one for "continuation lines".

Then you can just use the same prefix if you want to - and get the
semantics you have now for that helper.

But instead of just having "mergetag" as the prefix for all the lines
copied from the merge, wouldn't it be nice and easy to have "mergetag"
as the prefix for the *first* line of each copied tag, but then have
some other tag for lines 2..n?

I think that would be *way* easier to parse, and I think something
like that could be a good generic model for any multi-line thing -
have the first line tagged, and the rest have just the continuation
marker. You don't really need to repeat the tag over and over again
each line, it just causes ambiguoity as shown by this example.

But I don't have any really strong opinions on it. I just think it's a
good idea to make it easy to parse both mechanically and
human-visually, and "number of lines" doesn't strike me as being very
human-friendly.

Here is what I had in mind. An empty line in the tag payload would become
"mergetag \n" and a separate would become "mergetag\n". The consumer of
"cat-file commit" would be able to tell between the two anyway and if a
human _really_ cares, s/he can pipe it to "cat -e" or something.

Honestly, I do not care too much about human readability of "mergetag"
header. We could even store zlib-deflate-and-then-base85 the payload,
which _might_ be a better solution. For one thing, it would protect us
from potential NUL in the tag payload ;-).

And then I changed my mind again. Using a single SP indent for multi-line
header fields make things easy to view.

I am redoing the "signed-commit" series to also use this format.

The way I made the tag available to commit_tree() turned out to be a bit
too clever, by the way, and it would cause problems down the road when
these things need to be amended. Embedded "gpgsig" in a commit is about
the commit itself, and should not be carried over, but "mergetag" is about
the parent and should not be lost only because you wanted to fix a type
in your merge log message. I'll be redoing that part in the series and
hopefully the finished result would be ready for review after 1.7.8 final.
