* [PATCH 7/7] grep: do not diagnose misspelt revs with --no-index
From: Jeff King @ 2017-02-14 6:08 UTC (permalink / raw)

In-Reply-To: <20170214060021.einv7372exbxa23z@sigill.intra.peff.net>
If we are using --no-index, then our arguments cannot be
revs in the first place. Not only is it pointless to
diagnose them, but if we are not in a repository, we should
not be trying to resolve any names.

* [PATCH 6/7] grep: avoid resolving revision names in --no-index case
From: Jeff King @ 2017-02-14 6:07 UTC (permalink / raw)
To: Jonathan Tan; +Cc: git, gitster
In-Reply-To: <20170214060021.einv7372exbxa23z@sigill.intra.peff.net>
We disallow the use of revisions with --no-index, but we
don't actually check and complain until well after we've
parsed the revisions.
This is the cause of a few problems:
1. We shouldn't be calling get_sha1() at all when we aren't
in a repository, as it might access the ref or object
databases. For now, this should generally just return
failure, but eventually it will become a BUG().
2. When there's a "--" disambiguator and you're outside a
repository, we'll complain early with "unable to resolve
revision". But we can give a much more specific error.
3. When there isn't a "--" disambiguator, we still do the
normal rev/path checks. This is silly, as we know we
cannot have any revs with --no-index. Everything we see
must be a path.
Outside of a repository this doesn't matter (since we
know it won't resolve), but inside one, we may complain
unnecessarily if a filename happens to also match a
refname.
This patch skips the get_sha1() call entirely in the
no-index case, and behaves as if it failed (with the
exception of giving a better error message).

* [PATCH 5/7] grep: fix "--" rev/pathspec disambiguation
From: Jeff King @ 2017-02-14 6:05 UTC (permalink / raw)
To: Jonathan Tan; +Cc: git, gitster
In-Reply-To: <20170214060021.einv7372exbxa23z@sigill.intra.peff.net>
If we see "git grep pattern rev -- file" then we apply the
usual rev/pathspec disambiguation rules: any "rev" before
the "--" must be a revision, and we do not need to apply the
verify_non_filename() check.
But there are two bugs here:
1. We keep a seen_dashdash flag to handle this case, but
we set it in the same left-to-right pass over the
arguments in which we parse "rev".
So when we see "rev", we do not yet know that there is
a "--", and we mistakenly complain if there is a
matching file.
We can fix this by making a preliminary pass over the
arguments to find the "--", and only then checking the rev
arguments.
2. If we can't resolve "rev" but there isn't a dashdash,
that's OK. We treat it like a path, and complain later
if it doesn't exist.
But if there _is_ a dashdash, then we know it must be a
rev, and should treat it as such, complaining if it
does not resolve. The current code instead ignores it
and tries to treat it like a path.
This patch fixes both bugs, and tries to comment the parsing
flow a bit better.
It adds tests that cover the two bugs, but also some related
situations (which already worked, but this confirms that our
fixes did not break anything).

* [PATCH 4/7] grep: re-order rev-parsing loop
From: Jeff King @ 2017-02-14 6:04 UTC (permalink / raw)
To: Jonathan Tan; +Cc: git, gitster
In-Reply-To: <20170214060021.einv7372exbxa23z@sigill.intra.peff.net>
We loop over the arguments, but every branch of the loop
hits either a "continue" or a "break". Surely we can make
this simpler.
The final conditional is:
if (arg is a rev) {
... handle rev ...
continue;
}
break;
We can rewrite this as:
if (arg is not a rev)
break;
... handle rev ...
That makes the flow a little bit simpler, and will make
things much easier to follow when we add more logic in
future patches.

out).

This could be squashed into the previous patch.
I didn't end up using the "nongit" helper, because we actually have to
do some other setup inside the subshell (this is the reason the earlier
tests in this script don't use the helper, either).

* [PATCH 2/7] grep: do not unnecessarily query repo for "--"
From: Jeff King @ 2017-02-14 6:03 UTC (permalink / raw)
To: Jonathan Tan; +Cc: git, gitster
In-Reply-To: <20170214060021.einv7372exbxa23z@sigill.intra.peff.net>
From: Jonathan Tan <jonathantanmy@google.com>
When running a command of the form
git grep --no-index pattern -- path
in the absence of a Git repository, an error message will be printed:
fatal: BUG: setup_git_env called without repository
This is because "git grep" tries to interpret "--" as a rev. "git grep"
has always tried to first interpret "--" as a rev for at least a few
years, but this issue was upgraded from a pessimization to a bug in
commit 59332d1 ("Resurrect "git grep --no-index"", 2010-02-06), which
calls get_sha1 regardless of whether --no-index was specified. This bug
appeared to be benign until commit b1ef400 ("setup_git_env: avoid blind
fall-back to ".git"", 2016-10-20) when Git was taught to die in this
situation. (This "git grep" bug appears to be one of the bugs that
commit b1ef400 is meant to flush out.)
Therefore, always interpret "--" as signaling the end of options,
instead of trying to interpret it as a rev first.

* [PATCH 1/7] grep: move thread initialization a little lower
From: Jeff King @ 2017-02-14 6:02 UTC (permalink / raw)
To: Jonathan Tan; +Cc: git, gitster
In-Reply-To: <20170214060021.einv7372exbxa23z@sigill.intra.peff.net>
Originally, we set up the threads for grep before parsing
the non-option arguments. In 53b8d931b (grep: disable
threading in non-worktree case, 2011-12-12), the thread code
got bumped lower in the function because it now needed to
know whether we got any revision arguments.
That put a big block of code in between the parsing of revs
and the parsing of pathspecs, both of which share some loop
variables. That makes it harder to read the code than the
original, where the shared loops were right next to each
other.
Let's bump the thread initialization until after all of the
parsing is done.
Signed-off-by: Jeff King <peff@peff.net>

I double-checked to make sure no other code was relying on
the thread setup having happened. I think we could actually
bump it quite a bit lower (to right before we actually start
grepping), but I doubt it matters much in practice.

I know there are some terrible servers out there, but I think we can
discount any such server as horribly broken. Rewriting message-ids would
cause threading problems any time the sender referred to their own
messages. So "format-patch --thread" would fail to work, and even
replying to your own message from your "sent" folder would fail.

Based on my testing, gmail and comcast (and my work email) will preserve
the Message-Id header set by the client, but
hotmail.com/live.com/outlook.com will replace it with their generated value.
Based on a small sample of email addresses of those who post to this
list, it appears that most people are using their own MTA to send email,
or are using gmail, so they probably wouldn't be affected by the issue.

The clients are supposed to give Message-IDs, but because some
clients fail to do so, SMTP server implementations are allowed to
add an ID to avoid leaving a message nameless (IIRC, 6.3 in
RFC2821). So "replace" would be in violation.

Okay, got it! I will write-up those changes, and make sure nothing bad
happens. (Also, the one other function that calls handle_revision_opt,
parse_revision_opt needs to be fixed for any changes in
handle_revision_opt.)
I will do all of this in the next week (Unfortunately, exams!) and
submit a new version of this patch (Also, I need to update tests, add
documentation, and remove code that does this shorthand stuff for
other commands as per Matthieu's comments)

I wasn't aware of that expectation. My idea was to use NNTP as a way to
facilitate the development of a new git utility that would serve as the
inverse of git-send-email (sort of like the relationship between git
format-patch and git am), rather than using a
IIRC, I had posted some proof-of-concept Perl code to do so back in
August in
<DM5PR17MB1353B99EBD5F4FD23360DD41D3ED0@DM5PR17MB1353.namprd17.prod.outlook.com>
Looking at public-inbox now at the archives of this group, it appears
that several of the messages I sent weren't archived for some reason
(and I didn't see any more responses to what I posted at the time). The
messages are accessible via NNTP when connecting to gmane though.
Also, looking at the source of the message I referenced, it appears that
my MUA decided to base64 encode the message for some reason (which may
have resulted in it getting filtered by those who I sent the message to).
I will look into this more now (given yours and Junio's responses).

Certainly, but it would be nice to be able to have it done automatically
by git format-patch (which I'll look into).

I think the best approach would be not to make including the message-id
values the default behavior. Specifying a new command-line option to
enable that behavior should address those concerns I think.

Perhaps, but should something like that not warrant a re-roll of sorts.
That is, one should reply to the partial patch series stating that there
is a bug that renders this particular patch (series) un-usable and the
re-roll could be posted as a reply to the original cover letter?

If you have the time, please take a look at the message-id I referenced.
If you need, I can re-post the proof-of-concept code.

Thank you for the advice; I'll look into it.
One concern I have regarding this idea is whether or not SMTP servers
typically replace a Message-Id header set by the client. If that's the
case, then this approach may unexpectedly fail for some people depending
on what email provider they use (if they don't maintain their own MTA
setup).

I agree. I've actually thought that it would be useful to mirror a
read-only copy of the mailing list on a public newsgroup that could be
accessed through a free provider such as eternal-september.org or the
Google groups interface. It certainly would reduce the potential losing
easy access to the archives of this email list if gmane and
public-inbox.org fail. But I suspect doing something like that would
potentially increase the spam volume substantially for regular
participants/contributors.

* [PATCH v2 00/19] object_id part 6
From: brian m. carlson @ 2017-02-14 2:31 UTC (permalink / raw)
To: git; +Cc: Jeff King, Michael Haggerty
This is another series in the continuing conversion to struct object_id.
This series converts more of the builtin directory and some of the refs
code to use struct object_id. Additionally, it implements an
nth_packed_object_oid function which provides a struct object_id version
of the nth_packed_object function, and a parse_oid_hex function that
makes parsing easier.
The patch to use parse_oid_hex in the refs code has been split out into
its own patch, just because I'm wary of that code and potentially
breaking things, and I want it to be easy to revert in case things go
wrong. I have no reason to believe it is anything other than fully
functional, however.
Changes from v1:
* Implement parse_oid_hex and use it.
* Make nth_packed_object_oid take a variable into which to store the
object ID. This avoids concerns about unsafe casts.
* Rebase on master.

In-Reply-To: <20170214023141.842922-1-sandals@crustytoothpaste.net>
Convert most of the code to use struct object_id, including struct
origin_data and struct merge_parents. Convert several instances of
hardcoded numbers into references to GIT_SHA1_HEXSZ.

* [PATCH v2 17/19] Convert object iteration callbacks to struct object_id
From: brian m. carlson @ 2017-02-14 2:31 UTC (permalink / raw)
To: git; +Cc: Jeff King, Michael Haggerty
In-Reply-To: <20170214023141.842922-1-sandals@crustytoothpaste.net>
Convert each_loose_object_fn and each_packed_object_fn to take a pointer
to struct object_id. Update the various callbacks. Convert several
40-based constants to use GIT_SHA1_HEXSZ.

* [PATCH v2 14/19] hex: introduce parse_oid_hex
From: brian m. carlson @ 2017-02-14 2:31 UTC (permalink / raw)
To: git; +Cc: Jeff King, Michael Haggerty
In-Reply-To: <20170214023141.842922-1-sandals@crustytoothpaste.net>
Introduce a function, parse_oid_hex, which parses a hexadecimal object
ID and if successful, sets a pointer to just beyond the last character.
This allows for simpler, more robust parsing without needing to
hard-code integer values throughout the codebase.
