Subject: Re: [PATCH v3 08/11] commit-graph: implement generation data chunk
Date: Sat, 22 Aug 2020 15:09:35 +0200	[thread overview]
Message-ID: <85tuwuj08g.fsf@gmail.com> (raw)
In-Reply-To: <4e746628acdb49af5e8eb788864156f54724d4fa.1597509583.git.gitgitgadget@gmail.com> (Abhishek Kumar via GitGitGadget's message of "Sat, 15 Aug 2020 16:39:40 +0000")

All right, it looks like this patch implements first part of step 2.)
and step 3.) in the following plan of adding support for geeration
number v2:

1. compute generation numbers v2, i.e. corrected commit date
2. store corrected commit date [offsets] in new GDAT chunk,
   unless backward-compatibility concerns require us to not to
3. load [and compute] corrected commit date from commit-graph
   storing it as 'generation' field of `struct commit_graph_data`,
   unless backward-compatibility concerns require us to store
   topological levels (generation number v1) in there instead
4. use generation number v2 in more places, where we had to turn
   off using v1 for performance reasons

Fortunately, we have fixed this issue, and Git does no longer die when
it encounters commit-graph format version that it does not understand.

Should we say anything about storing 64 bit corrected commit date
(geeration number v2) as 32 bit corrected commit date offset?

Note that the fact that we do not have special code for handling
mixed-version layers in split commit-graph is not [that] dangerous, as
we don't read this new data yet.  Splitting it to patch 09/11 (next
patch) makes this patch simpler.

All right.

It might be a good idea to add documentation of this chunk (and only
about this chunk) to Documentation/technical/commit-graph-format.txt

All right, define new chunk and increase the maximum number of chunks
commit-graph file can have.

All right.  The size of GDAT chunk is defined by the number of commits,
so nothink more is needed.

WARNING: The above does not properly handle clamped data.

If the offset is maximum value that can be stored in 32 bit field, that
is GENERATION_NUMBER_V2_OFFSET_MAX for more that one commit, we wouldn't
know which commit has greater generation number v2 because of this clamping.
The 'generation' data needs to be set to GENERATION_NUMBER_V2_MAX (which
in turn needs to be smaller than GENERATION_NUMBER_INFINITY).  This is
not done here!

All the above complication would not be an issue if we stored 64 bit
corrected commit date directly, instead of storing 32 bit corrected
commit date offsets. Storing offsets saves at most 4/(2*H + 16 + 4) = 7%
of commit-graph file size (OIDL + CDAT + GDAT with offsets), when
160-bit/20-byte SHA-1 hash is used.

Should we convert GENERATION_NUMBER_V1_MAX into GENERATION_NUMBER_MAX
here, for easier handling of clamped values of generation numbers later
on in backward-compatibile way, without special-casing for v1 and v2?


Here we load and perhaps compute generation number, using v2 if possible
(from GDAT + commit date), with fallback to v1 (from CDAT).

Almost all right... but should this reading be a part of this patch, or
split off into separate patch?

All right, here we store the iformation if we should write the GDAT
chunk, taking into account among other things state of the
GIT_TEST_COMMIT_GRAPH_NO_GDAT enviroment variable.

Side note: it is a bit funny that some of write_graph_chunk_*()

This GENERATION_NUMBER_V2_OFFSET_MAX symbolic constant (or equivalet)
should be defined in this patch and not in previous one, in my opinion.

This change in whitespace is, I think, incorrect.

Hmmm... so the GDAT chunk does not have a header, and is not versioned.
Does this mean that to move to generation number v3, or add some
additional reachability labeling we would need to either rename the
chunk or add new one?

But by default we do write the GDAT chunk.

All right, we examine if GDAT chunk is present.

Many commit-graph tests would probably need to be updated; at least
those that make use if `git test-tool read-graph`.

All right, a fix for issue that is relevant only after this change, now
that there can be more than one extra chunk.

What this change is about?  Is it about the fact that we have not added
support for checking correctness of GDAT chunk to `git commit-graph
verify`?  But in previous commit we did modify verify_commit_graph()...

I guess this change is because with GDAT chunk present the positions of
relevant bits that we want to corrupt change (I guess because we have
extra chunk in chunk lookup section).

Someone else would have to verify if this change is in fact correct, if
it was not done already.

All right, we add setup for testing no GDAT case (as if the commit-graph
file was written by "Old" Git).

All right, we compare more modes, among others the no-GDAT case.

Nice futureproofing!

OK, now we test yet another variant of commit-graph file: one without
the GDAT chunk (testing for backward compatibility with "Old" Git).

All right.

All right, s/test_three_modes/test_all_modes/... which admitedly could
have been separate pure refactoring patch, but it is not necessary.
