This function mark_new_skip_worktree() has an argument named the_index
which is also the name of a global variable. While they have different
types (the global the_index is not a pointer) mistakes can easily
happen and it's also confusing for readers. Rename the function
argument to something other than the_index.

Prior to fba92be8f7, this code implicitly (and incorrectly) assumes
the_index when running the exclude machinery. fba92be8f7 helps show
this problem clearer because unpack-trees operation is supposed to
work on whatever index the caller specifies... not specifically
the_index.
Update the code to use "istate" argument that's originally from
mark_new_skip_worktree(). From the call sites, both in unpack_trees(),
you can see that this function works on two separate indexes:
o->src_index and o->result. The second mark_new_skip_worktree() so far
has incorecctly applied exclude rules on o->src_index instead of
o->result. It's unclear what is the consequences of this, but it's
definitely wrong.

Both functions that are updated in this commit are called by
verify_absent(), which is part of the "unpack-trees" operation that is
supposed to work on any index file specified by the caller. Thanks to
Brandon [1] [2], an implicit dependency on the_index is exposed. This
commit fixes it.
In both functions, it makes sense to use src_index to check for
exclusion because it's almost unchanged and should give us the same
outcome as if running the exclude check before the unpack.
It's "almost unchanged" because we do invalidate cache-tree and
untracked cache in the source index. But this should not affect how
exclude machinery uses the index: to see if a file is tracked, and to
read a blob from the index instead of worktree if it's marked
skip-worktree (i.e. it's not available in worktree)

Make the attr API take an index_state instead of assuming the_index in
attr code. All call sites are converted blindly to keep the patch
simple and retain current behavior. Individual call sites may receive
further updates to use the right index instead of the_index.
There is one ugly temporary workaround added in attr.c that needs some
more explanation.
Commit c24f3abace (apply: file commited * with CRLF should roundtrip
diff and apply - 2017-08-19) forces one convert_to_git() call to NOT
read the index at all. But what do you know, we read it anyway by
falling back to the_index. When "istate" from convert_to_git is now
propagated down to read_attr_from_array() we will hit segfault
somewhere inside read_blob_data_from_index.
The right way of dealing with this is to kill "use_index" variable and
only follow "istate" but at this stage we are not ready for that:
while most git_attr_set_direction() calls just passes the_index to be
assigned to use_index, unpack-trees passes a different one which is
used by entry.c code, which has no way to know what index to use if we
delete use_index. So this has to be done later.

Ugh I remember this when I was doing some refactoring to the attr
subsystem a year or so ago. I really wanted to get rid of the whole
"direction" thing because if I remember correctly its one of the only
remaining globals that affects the outcome of an attr check (everything
else was converted to use the attr check struct. I always got way to
far into the weeds when trying to do that too. I'm not expecting that
from this series (since its way out of scope) but maybe it'll be easier
afterwards.

It's not that much easier. This direction thing is still global by
design. It would be great if we have something like Scheme's parameter
(aka. dynamic scoping iirc) then we can still scope this nicely. Git
does not live in such worlds.

Yeah i realized this after sending. Either way thanks for simplifying
the global state by getting ride of the index global.

Make the convert API take an index_state instead of assuming the_index
in convert.c. All external call sites are converted blindly to keep
the patch simple and retain current behavior. Individual call sites
may receive further updates to use the right index instead of
the_index.

From: Nguyễn Thái Ngọc Duy @ 2018-06-06 7:39 UTC (permalink / raw)
To: pclouds; +Cc: bmwill, git, newren, ramsay
Make the match_patchspec API and friends take an index_state instead
of assuming the_index in dir.c. All external call sites are converted
blindly to keep the patch simple and retain current behavior.
Individual call sites may receive further updates to use the right
index instead of the_index.

write_eolinfo() does take an istate as function argument and it should
be used instead of the_index.

checkout-index.c needs update because if checkout->istate is NULL,
ie_match_stat() will crash. Previously this is ie_match_stat(&the_index, ..)
so it will not crash, but it is not technically correct either.

Since attr checking API now take the index, there's no need to set an
index in advance with this call. Most call sites are straightforward
because they either pass the_index or NULL (which defaults back to
the_index previously). There's only one suspicious call site in
unpack-trees.c where it sets a different index.
This code in unpack-trees is about to checking out entries from the
new/temporary index after merging is done in it. The attributes will
be used by entry.c code to do crlf conversion if needed. entry.c now
respects struct checkout's istate field, and this field is correctly
set in unpack-trees.c, there should be no regression from this change.

Make some index API take an index_state instead of assuming the_index
in read-cache.c. All external call sites are converted blindly to keep
the patch simple and retain current behavior. Individual call sites
may receive further updates to use the right index instead of the_index.

While the_index is not actually a macro, its use throughout the code
base is dangerous because developers sometimes may not see that some
function is using the_index (instead of some other index that the devs
are interested in).
By keeping the_index part of this NO_ macro, we try to reduce its use
more and more until it's completely gone.

This function mark_new_skip_worktree() has an argument named the_index
which is also the name of a global variable. While they have different
types (the global the_index is not a pointer) mistakes can easily
happen and it's also confusing for readers. Rename the function
argument to something other than the_index.

Prior to fba92be8f7, this code implicitly (and incorrectly) assumes
the_index when running the exclude machinery. fba92be8f7 helps show
this problem clearer because unpack-trees operation is supposed to
work on whatever index the caller specifies... not specifically
the_index.
Update the code to use "istate" argument that's originally from
mark_new_skip_worktree(). From the call sites, both in unpack_trees(),
you can see that this function works on two separate indexes:
o->src_index and o->result. The second mark_new_skip_worktree() so far
has incorecctly applied exclude rules on o->src_index instead of
o->result. It's unclear what is the consequences of this, but it's
definitely wrong.

A somewhat curious finding: when I was rebuilding and re-testing all
23 patches, I got a failure on this patch in test 31 of
t7063-status-untracked-cache.sh. I did not get any test failures with
any of the other patches. However, after re-running that test or the
whole suite half a dozen times with just up to this patch applied, I
was not able to trigger the failure again. Is there a rare race in
that testcase? I certainly don't see anything in this patch that
appears problematic, and the fact that I couldn't readily reproduce
suggests it could well have been there before any of these patches.
Everything else in the patch looks fine to me.

Untracked cache tests are very time-sensitive. I'll try to run and
re-run them a couple times to understand more. Thanks for pointing it
out.

after hours of running tests, either with full 23 patches or just the
first 4, and failing to catch the failure, i declare (or more like,
pray) that you ran into a crack of time that led to a race. I'll take
no action on this, but I'll remember this and watch out for untracked
cache related mails for some time.

Both functions that are updated in this commit are called by
verify_absent(), which is part of the "unpack-trees" operation that is
supposed to work on any index file specified by the caller. Thanks to
Brandon [1] [2], an implicit dependency on the_index is exposed. This
commit fixes it.
In both functions, it makes sense to use src_index to check for
exclusion because it's almost unchanged and should give us the same
outcome as if running the exclude check before the unpack.
It's "almost unchanged" because we do invalidate cache-tree and
untracked cache in the source index. But this should not affect how
exclude machinery uses the index: to see if a file is tracked, and to
read a blob from the index instead of worktree if it's marked
skip-worktree (i.e. it's not available in worktree)

Make the attr API take an index_state instead of assuming the_index in
attr code. All call sites are converted blindly to keep the patch
simple and retain current behavior. Individual call sites may receive
further updates to use the right index instead of the_index.
There is one ugly temporary workaround added in attr.c that needs some
more explanation.
Commit c24f3abace (apply: file commited with CRLF should roundtrip
diff and apply - 2017-08-19) forces one convert_to_git() call to NOT
read the index at all. But what do you know, we read it anyway by
falling back to the_index. When "istate" from convert_to_git is now
propagated down to read_attr_from_array() we will hit segfault
somewhere inside read_blob_data_from_index.
The right way of dealing with this is to kill "use_index" variable and
only follow "istate" but at this stage we are not ready for that:
while most git_attr_set_direction() calls just passes the_index to be
assigned to use_index, unpack-trees passes a different one which is
used by entry.c code, which has no way to know what index to use if we
delete use_index. So this has to be done later.

Make the convert API take an index_state instead of assuming the_index
in convert.c. All external call sites are converted blindly to keep
the patch simple and retain current behavior. Individual call sites
may receive further updates to use the right index instead of
the_index.

From: Nguyễn Thái Ngọc Duy @ 2018-06-06 17:02 UTC (permalink / raw)
To: pclouds; +Cc: bmwill, git, newren, ramsay
Make the match_patchspec API and friends take an index_state instead
of assuming the_index in dir.c. All external call sites are converted
blindly to keep the patch simple and retain current behavior.
Individual call sites may receive further updates to use the right
index instead of the_index.

write_eolinfo() does take an istate as function argument and it should
be used instead of the_index.

checkout-index.c needs update because if checkout->istate is NULL,
ie_match_stat() will crash. Previously this is ie_match_stat(&the_index, ..)
so it will not crash, but it is not technically correct either.

Since attr checking API now take the index, there's no need to set an
index in advance with this call. Most call sites are straightforward
because they either pass the_index or NULL (which defaults back to
the_index previously). There's only one suspicious call site in
unpack-trees.c where it sets a different index.
This code in unpack-trees is about to checking out entries from the
new/temporary index after merging is done in it. The attributes will
be used by entry.c code to do crlf conversion if needed. entry.c now
respects struct checkout's istate field, and this field is correctly
set in unpack-trees.c, there should be no regression from this change.

This code is much clearer and easier to reason about than stashing off
use_index. I had to dig for a bit through history to try to
understand the old code and why it was written that way, but the new
code just makes sense.

Make some index API take an index_state instead of assuming the_index
in read-cache.c. All external call sites are converted blindly to keep
the patch simple and retain current behavior. Individual call sites
may receive further updates to use the right index instead of the_index.

There's also a refresh_cache_entry() call about ten lines after this;
since you converted all other make_cache_entry() and
refresh_cache_entry() calls in this patch, I'm curious if that one was
left out for a reason or was just an oversight.
There are also a lot of add_cache_entry() calls in this function. I'm
guessing we should either convert all of those too, or just change
back this particular make_index_entry to make_cache_entry() as it was;
it seems weird to have a mix of explicit the_index and implicit
the_index usages in the same function. If we convert them all,
perhaps we should consider having merge_options store the index we're
working on? If you want to punt this until later or leave it for me
while I make all my ongoing merge-recursive changes, that's fine.
Just thought I'd point it out.

Ah I didn't mean to convert or kill refresh_cache_entry(), not outside
read-cache.c. I rely on NO_THE_INDEX_COMPATIBILITY_MACROS to catch
*cache* functions and if we set it in this file, we're going to have a
lot more work to do and plenty of the_index will show up.

Yes some files still have the mix of the_index and *cache*(). This one
and apply.c come to mind. There's more work to do to kill all
the_index outside builtin/

Right you're updating merge-recursive.c, I'd love it if you could
define NO_THE_INDEX_COMPATIBILITY_MACROS here. Yes merge_options
sounds like a good place to tell merge-recursive where to get a struct
index_state.

Yeah, there's also low-level common files like sha1-file.c or
ll-merge.c which now have &the_index in them (or more references to
it). Clearly those need to be propagated up, but as you say, there's
more work to do. Your patch series just moves things in the right
direction.

Sure, I can tackle that.

While the_index is not actually a macro, its use throughout the code
base is dangerous because developers sometimes may not see that some
function is using the_index (instead of some other index that the devs
are interested in).
By keeping the_index part of this NO_ macro, we try to reduce its use
more and more until it's completely gone.

Thanks for tackling this. The first 8 patches look good to me other
than the typo I pointed out on patch 4. However, my eyes glazed over
a bit on the attr.c stuff in patch 7 that you specifically mentioned
in the commit message, so my "looks good" doesn't count for as much on
that one.
I'm getting sleepy, but I'll try to circle back and look over the rest
of the patches in the next few days.

I re-read the attr.c stuff in patch 7; looks good to me and the new
series makes the code much more readable in the end.

I read over the rest. Found a small grammatical error in a commit
message. Found multiple places that still need conversion, from
pushing up &the_index usages to callers of ll-merge.c and sha1-file.c
instead of having them in those files, to mixes of _cache_ and _index_
functions as in apply.c and merge-recursive.c. However, Duy pointed
out there was more work to do, and this series is a step in the right
direction and a good start.

Yes. This is just fyi, 40 patches later, i'm down to leaving the_index
in three files outside builtin/: merge-recursive, notes-merge.c and
transport.c. Even after the conversion we may need some more follow-up
patches because it now shows places where we should _not_ touch the
index at all, which may involve not simply passing NULL index_state to
some functions, but fixing them up to tolerate NULL index_state. So
it's going to be a few patch series until the_index is gone for good
[1].
[1] but like cheap horror movies, there's always a sequel:
the_repository is still spread in many places and hides dependencies
in the same way. We can't do anything about it though until struct
repository conversion is more or less complete.

I was just about to send you an email to ask if you were continuing on
with the series. I need diff-lib.c converted in order to make the
changes Junio suggested to index_has_changes at
https://public-inbox.org/git/xmqqvaaz5jcv.fsf@gitster-ct.c.googlers.com/.
Since you're already working on that, I won't duplicate your effort.
Thanks for tackling all of this. :-)

And I forgot one thing. There are other hidden dependencies as well.
Like hold_locked_index() will assume $GIT_DIR/index, but when you take
an arbitrary 'struct index_state *' I don't think you can make that
kind of assumption. This is mostly a note to myself in case I forget
it again.

I'm not sure if it's possible to cherry pick this patch to continue
your work (because of dependencies between patches) but it's
https://gitlab.com/pclouds/git/commits/really-kill-the-index, commit
"merge.c: remove...".
Or you just leave it to me, update has_index_changes() to always take
'struct index_state *' and just pass &the_index in all uninteresting
places. (Or not update at all if it's really not needed for your work)
What about merge-recursive.c? Given that this whole thing will take
many release cycles to finish, your work may get merged before mine
and I could do the conversion now (and resolve conflicts and resubmit
later). Of course if you like to keep merge-recursive.c the_index-free
now, I will not stop you ;-)

Actually, I'm thinking maybe I should just push that series forward
without changing index_has_changes() to take an istate (since it's not
actually important to that series yet), and then once your changes
land, then update the function appropriately. (Or maybe your series
will update that function too.)

I was just worried that since I was making changes in
merge-recursive.c that it'd cause you conflict pain, so I offered to
convert it. If that pain doesn't bother you, feel free to do the
conversion and we'll just work through the minor conflicts as we go.
Besides, sounds like you've converted nearly all of git, so it may
make sense to just keep it together in one big series.

OK let's just "quickly" get your series in then. I still have a few
files to go and a couple more places to look back and ponder. I'm in
no hurry to convert merge-recursive now :D

Actually could you quickly check if I pass the right index in the
following patch? I realize you only have one extra index, but I don't
know if it gets passed elsewhere and in some function I'm supposed to
use another index than the default "o->repo->index". Sometimes
o->repo->index is not the correct answer.
It takes many patches to get to this stage, so if you diff context
looks so strange to you, just ignore this for now. I'll eventually
send this one out in a series.
PS. I put a 'struct repository *' in 'struct merge_options' instead
because it turns out we do need full repo struct in some function.

Yes, this looks right.
It'd be nice to be able to apply the patch locally so I could also
look at the --color-words version, but it's not a real big deal.
In general, this is how the index stuff works in merge-recursive:
* In unpack_trees_start(), we call unpack_trees() using the_index as
src, and tmp_index as dest.
* As soon as unpack_trees() finishes, we swap: (orig_index,
the_index) = (the_index, tmp_index).
* We ONLY use orig_index (also called unpack_opts.src_index) in the
was_*() family of functions, which query about what the index was like
before the merge started. (To name these functions explicitly:
was_tracked_and_matches(), was_tracked(), and was_dirty()). ALL other
callsites within merge-recursive.c should be operating on the_index,
or, after your patch, o->repo->index.
(Also, if you want to avoid merge conflicts, you might want to avoid
unrelated changes like the whitespace and alignment fixes. You'll be
happy to know, though, that I think I fixed them all up as part of the
en/merge-recursive-cleanup series in pu.)

Junio, just to be clear, I think I'll withdraw this 23-patch series
(reviews are still welcome though). It does fix some potential bugs
but it's not that critical. This will let me merge it with the other
40+ patches and reorganize better (after all this started out as a
single rfc patch, I didn't realize what I got myself into)
