I think so. Added a reference to packed-refs

I think it's beyond the scope of the document. In reftable the
library, I added an option to validate for file/dir conflicts.

(Google's deployment doesn't do the validation completely correctly.
We had a ref ending in '/' for example.)

Beyond 4096 bytes (size of a page on x86), I don't think there is a
need for powers of two. What makes for a good block size would also be
decided by the characteristics of the underlying storage system. At
google, we use 64k, IIRC.

yes, that works. In practice, you find the last restart before the
key, and then iterate until you find a key that is >= the wanted key.
There is no real need to find the next restart.

reflog records encode update_index in the key, which may lead to keys
with zero bytes. So you can't rely on zero termination.

Here, and in other places, I would like to avoid annotating rationales
in detail.  First of all, this was Shawn's spec; if I go and rewrite
whole sections, the authorship becomes muddled. Second, a lot of the
"why" will invite questions how to do it differently to achieve the
same objectives (see below, where you muse about '<' and '>'), and
that's a past station given that it's in JGit. Finally, all these
edits cause extra work with conflict resolution in follow-up changes
in the series. If we want to editorialize more, I'd rather do it in a
follow up series.

I think update_index is poorly named. I think it's supposed to be the
index into an ordered array of updates.

A better name would be 'logical timestamp'. It is a timestamp, because
we use it to determine which update came first, but it is 'logical'
because it can't depend on actual clocks, because of synchronization
problems.  Inside Google, I think we use microsecond Spanner
timestamps of the database transaction on the global ref database.

In a local setting, it's good enough to use a sequential number, which
is determined by incrementing the last update_index.

That's what I thought initially too , but it is a dangerous
assumption. See reftable/merged.c,  merged_iter_next_entry() for a
comment.

At Google, in the datacenter deployment, update indices of different
reftable can overlap. This can happen when compaction and replication
delay interact.

This is addressed in the follow-up change for SHA256. Let's leave this alone.

All of the keys prefix compressed, so most refnames are incomplete.

I honestly don't know about the reason. reflogs will compress well
(because there is lots of ascii text), but it makes the format
needlessly complex IMO. But it's there, so we can't do much about it
now.

If you store reflogs in ascii files, both for convention, and  to
separate the name from the email. Internally, it's much more
convenient to not have the '<' '>'. For any practical application of
the email address (Say, you want to send out an email to the user),
you'll need to strip off the < >

That's up to the caller to decide. I think JGit uses the committer
identity, but I'd have to check.

gain in what dimension? Space-wise, the zlib compression will remove

quoting the spec:

"Log record entries use `log_type` to indicate what follows:

* `0x0`: deletion; no log data."

the creation would be the appearance of a reflog record for the ref.
You'd have to search back in time to decide if a reflog record it was
an update to an existing record or a creation.
