4 years agoavoid using a second db connection for writes
Joey Hess [Wed, 20 Oct 2021 16:32:46 +0000 (12:32 -0400)]
avoid using a second db connection for writes

This is a potentially breaking change in a very delicate area. However,
examining the code path for writes, I don't see any benefit to opening a
second db connection for them. If the write throws an exception,
commitDb will retry it with a new db connection.

A potential benefit to not opening a second db connection, beyond using
less resources, is it just might avoid problems in WSL with sqlite that
I have hypothesized are caused by multiple db connections.

Commit 5f9eff3f32e0101ee673c3dde221f0f27f32e3c8 explains why it needs to
shut down the db connection to force the database to be updated on disk:
When closeDb does not get called, garbage collection of DbHandle may not
give the workterThread time to cleanly shut down before git-annex exits,
resulting in a recently written change not reaching disk.

eliminate single/multi writer distinction

After commit f4bdecc4ecce8bcbb2d8ccbb524ba1f3f76565ba, there is no
longer any distinction between SingleWriter and MultiWriter's handling
of read after write.

Databases that were SingleWriter still have lock files that are used to
prevent multiple writers.

This does make writing to such databases a bit more expensive,
because the MultiWriter code path that is now used opens a second db
connection in order to write to them.

improve sqlite MultiWriter handling of read after write

This removes a messy caveat that was easy to forget and caused at least one
bug. The price paid is that, after a write to a MultiWriter db, it has to
close the db connection that it had been using to read, and open a new
connection. So it might be a little bit slower. But, writes are usually
batched together, so there's often only a single write, and so there should
not be much of a slowdown. Notice that SingleWriter already closed the db
connection after a write, so paid the same overhead.

This is the second try at fixing a bug: git-annex get when run as the first
git-annex command in a new repo did not populate all unlocked files.

avoid crashing tilde expansion on user who does not exist

git does not crash when there's a remote configured for a user who does
not exist, and this prevents git-annex from crashing too. Consider that
a user might exist on one system but not another, and the git repo be
moved between systems. So not crashing is desirable.

Note that git fetch seems to mishandle a remote path like ~foo/bar
when the user does not exist. While it does access ./~foo/bar,
and gets as far as running git-upload-pack on the path,
it then complains there is no such repo. So different parts of git seem
to be doing different things in that edge case. Anyway, git-annex does
not need to be bug-for-bug compatible with git.

The P2P protocol was added in that version, and used ever since, so
this code was only needed for interop with older versions.

"git-annex-shell commit" is used by newer git-annex versions, though
unnecessarily so, because the p2pstdio command makes a single commit at
shutdown. Luckily, it was run with stderr and stdout sent to /dev/null,
and non-zero exit status or other exceptions are caught and ignored. So,
that was able to be removed from git-annex-shell too.

git-annex-shell inannex, recvkey, sendkey, and dropkey are still used by
gcrypt special remotes accessed over ssh, so those had to be kept.
It would probably be possible to convert that to using the P2P protocol,
but it would be another multi-year transition.

Some git-annex-shell fields were able to be removed. I hoped to remove
all of them, and the very concept of them, but unfortunately autoinit
is used by git-annex sync, and gcrypt uses remoteuuid.

ImportableContentsChunkable

This improves the borg special remote memory usage, by
letting it only load one archive's worth of filenames into memory at a
time, and building up a larger tree out of the chunks.

When a borg repository has many archives, git-annex could easily OOM
before. Now, it will use only memory proportional to the number of
annexed keys in an archive.

Minor implementation wart: Each new chunk re-opens the content
identifier database, and also a new vector clock is used for each chunk.
This is a minor innefficiency only; the use of continuations makes
it hard to avoid, although putting the database handle into a Reader
monad would be one way to fix it.

It may later be possible to extend the ImportableContentsChunkable
interface to remotes that are not third-party populated. However, that
would perhaps need an interface that does not use continuations.

The ImportableContentsChunkable interface currently does not allow
populating the top of the tree with anything other than subtrees. It
would be easy to extend it to allow putting files in that tree, but borg
doesn't need that so I left it out for now.

avoid cursor jitter when updating progress display

When the progress display gets longer, and then shorter again, it causes
the cursor to jitter back and forth. Somehow I never noticed this until
this morning, but then it became intolerable to watch.

To fix it, pad the progress display to the maximum length it's occupied.
