While cryptohash has SHA3 support, it has not been updated for the final
version of the spec. Note that cryptonite has not been ported to all arches
that cryptohash builds on yet.
This was potentially a hole in the readonly mode armor even before my last
commit. If the user could push a git-annex branch to a repo, they could get
git-annex-shell to initialize the repo. After my last commit, the user
didn't even need to be allowed to push a branch to init the repo, so
this hole certianly needs to be closed now.
Now it suffices to run git remote add, followed by git-annex sync. Now the
remote is automatically initialized for use by git-annex, where before the
git-annex branch had to manually be pushed before using git-annex sync.
Note that this involved changes to git-annex-shell, so if the remote is
using an old version, the manual push is still needed.
Implementation required git-annex-shell be changed, so configlist can
autoinit a repository even when no git-annex branch has been pushed yet.
Unfortunate because we'll have to wait for it to get deployed to servers
before being able to rely on this change in the documentation.
Did consider making git-annex sync push the git-annex branch to repos that
didn't have a uuid, but this seemed difficult to do without complicating it
in messy ways.
It would be cleaner to split a command out from configlist to handle
the initialization. But this is difficult without sacrificing backwards
compatability, for users of old git-annex versions which would not use the
new command.
I think that the problem was caused by windows not having a concept of an
env var that is set, but to the empty string. So, GIT_ANNEX_SSHOPTION
got set to "" and was not seen as set at all.
Easy fix, which also makes git-annex sync a little faster is to not set
GIT_SSH, when GIT_ANNEX_SSHOPTION has no options. Might as well let git use
ssh per usual in this case, no need to run git-annex as the proxy ssh
command..
This fixes a reversion introduced by relative path changes back last winter.
The root cause is simplifyPath "../foo" was incorrectly yielding "foo".
absPathFrom seems quite horrible. Probably most things that use it should
use </> instead.
Git.Ref.headSha doesn't really work in direct mode as there's not a head,
so it was actually diffing against the empty tree and so not removing any
deleted files. Get the sha of the current branch instead, which is the same
thing Command.Sync does.
* proxy: Fix proxy git commit of non-annexed files in direct mode.
* proxy: If a non-proxied git command, such as git revert
would normally fail because of unstaged files in the work tree,
make the proxied command fail the same way.
* Perform a clean shutdown when --time-limit is reached.
This includes running queued git commands, and cleanup actions normally
run when a command is finished.
* fsck: Commit incremental fsck database when --time-limit is reached.
Previously, some of the last files fscked did not make it into the
database when using --time-limit.
Note that this changes Annex.addCleanup hooks, to run after --time-limit
expires. Fsck was using such a hook to clean up after a
--incremental-schedule, and that shouldn't run when --time-limit exipires
it. So, instead, moved that cleanup code to be run by cleanupIncremental.
Resulted in some data type juggling.
I've seen rss feeds that have no permalinks, only guids (which are
sometimes in the form of permalinks, argh/sigh).
I had previously avoided trusting guids to be globally unique, because my
survey of rss feeds that I subscribe to shows a lot of pretty bad
"guids" like "2 at http://serialpodcast.org" or even worse "oth20150401-hq".
Worry was that two podcasts that are generating guids so badly, that
there's no guarantee they're actually globally unique.
But, I'm seeing too many url changes that result in redundant files, so
let's try this. If feeds are so broken that guids overlap, they could just
as well incorrectly call them permalinks too.
"checkPresent baser" was wrong; the baser has a dummy checkPresent action
not the real one. So, to fix this, we need to call preparecheckpresent to
get a checkpresent action that can be used to check if chunks are present.
Note that, for remotes like S3, this means that the preparer is run,
which opens a S3 handle, that will be used for each checkpresent of a
chunk. That's a good thing; if we're resuming an upload that's already many
chunks in, it'll reuse that same http connection for each chunk it checks.
Still, it's not a perfectly ideal thing, since this is a different http
connection that the one that will be used to upload chunks. It would be
nice to improve the API so that both use the same http connection.
The branch needs to be created when merging from the remote in sync,
since we diff between it and the remote's sync branch. But git annex merge
should not be creating sync branches.
This was a reversion caused by the relative path changes in 5.20150113.
Other uses of addAuthorizedKeys seem to be ok. If the user enters a
directory like ~/annex, it writes GIT_ANNEX_SHELL_DIRECTORY=annex, and
git-annex-shell assumes that's relative to HOME.
This makes git annex unused use around 48 mb more memory than it did before,
but the massive increase in accuracy makes this worthwhile for all but the
smallest systems.
Also, I want to use the bloom filter for sync --all --content, to avoid
dropping files that the preferred content doesn't want, and 1/1000
false positives would be far too many in that use case, even if it were
acceptable for unused.
Actual memory use numbers:
1000: 21.06user 3.42system 0:26.40elapsed 92%CPU (0avgtext+0avgdata 501552maxresident)k
1000000: 21.41user 3.55system 0:26.84elapsed 93%CPU (0avgtext+0avgdata 549496maxresident)k
10000000: 21.84user 3.52system 0:27.89elapsed 90%CPU (0avgtext+0avgdata 549920maxresident)k
Based on these numbers, 10 million seemed a better pick than 1 million.
backup: Use new "anything" terminal. This means that content that
is not unused, but has no associated file will be wanted by backup repos.
unwanted: "not anything" will result in any and all content moving
off of these repos.
incremental backup: Remove the "(include=* or unused)",
so it matches content that has no associated files
but is not unused.
client: Add a include=* to the expression. This limits it to matching
only files in the work tree. Without this change, sync --all --content
would match a key against the expression, and since it matches
exclude=archive/*, the client repo would have wanted the file content.
The "and not unused" would have kept unused objects out, but not
objects that were not known to be unused, or objects that another branch
referred to. In practice, everything would have flooded into client repos
without this change.
In my tests, this has to be set when uploading a file to the bucket
and then the file can be accessed using the bucketname.s3.amazonaws.com
url.
Setting it when creating the bucket didn't seem to make the whole bucket
public, or allow accessing files stored in it. But I have gone ahead and
also sent it when creating the bucket just in case that is needed in some
case.
This is especially useful because the caller doesn't need to generate valid
url keys, which involves some escaping of characters, and may involve
taking a md5sum of the url if it's too long.
The one exception is in Utility.Daemon. As long as a process only
daemonizes once, which seems reasonable, and as long as it avoids calling
checkDaemon once it's already running as a daemon, the fcntl locking
gotchas won't be a problem there.
Annex.LockFile has it's own separate lock pool layer, which has been
renamed to LockCache. This is a persistent cache of locks that persist
until closed.
This is not quite done; lockContent stil needs to be converted.
