support git remotes that need http basic auth
using git credential to get the password

One thing this doesn't do is wrap the password prompting inside the prompt
action. So with -J, the output can be a bit garbled.

better error message when git config fails to parse remote config
Rather than leaking the name of the temp file, just say the config parse
failed, and where the config was downloaded from.

Not closing the bug report because two issues were reported in the same
bug report, because the universe wants me to continually re-read old
unclosed bug reports to waste my time determining what still needs to be
done.

avoid ugly error message
Http remotes that do expose a git config file, but are not initialized
resulted in an ugly and unncessary error message, now sqelched.

When git-annex-shell configlist is run w/o the autoinit field, it may
not generate a uuid for the repository. So in that case, it's not
unexpected for the config it does list to not include a UUID, and
dumping out the config in a warning message is not needed.

If configlist is asked to autoinit and we don't get back a config with a
UUID in it, that suggests some problem, and what we got back may not be
a config at all but some diagnostic message, so it does make sense to
output it then.

be stricter about rejecting invalid configurations for remotes
This is a first step toward that goal, using the ProposedAccepted type
in RemoteConfig lets initremote/enableremote reject bad parameters that
were passed in a remote's configuration, while avoiding enableremote
rejecting bad parameters that have already been stored in remote.log

This does not eliminate every place where a remote config is parsed and a
default value is used if the parse false. But, I did fix several
things that expected foo=yes/no and so confusingly accepted foo=true but
treated it like foo=no. There are still some fields that are parsed with
yesNo but not not checked when initializing a remote, and there are other
fields that are parsed in other ways and not checked when initializing a
remote.

This also lays groundwork for rejecting unknown/typoed config keys.

git-annex config annex.largefiles
annex.largefiles can be configured by git-annex config, to more easily set
a default that will also be used by clones, without needing to shoehorn the
expression into the gitattributes file. The git config and gitattributes
override that.

Whenever something is added to git-annex config, we have to consider what
happens if a user puts a purposfully bad value in there. Or, if a new
git-annex adds some new value that an old git-annex can't parse.
In this case, a global annex.largefiles that can't be parsed currently
makes an error be thrown. That might not be ideal, but the gitattribute
behaves the same, and is almost equally repo-global.

Performance notes:

git-annex add and addurl construct a matcher once
and uses it for every file, so the added time penalty for reading the global
config log is minor. If the gitattributes annex.largefiles were deprecated,
git-annex add would get around 2% faster (excluding hashing), because
looking that up for each file is not fast. So this new way of setting
it is progress toward speeding up add.

git-annex smudge does need to load the log every time. As well as checking
the git attribute. Not ideal. Setting annex.gitaddtoannex=false avoids
both overheads.

use filepath-bytestring for annex object manipulations
git-annex find is now RawFilePath end to end, no string conversions.
So is git-annex get when it does not need to get anything.
So this is a major milestone on optimisation.

Benchmarks indicate around 30% speedup in both commands.

Probably many other performance improvements. All or nearly all places
where a file is statted use RawFilePath now.

convert TopFilePath to use RawFilePath
Adds a dependency on filepath-bytestring, an as yet unreleased fork of
filepath that operates on RawFilePath.

Git.Repo also changed to use RawFilePath for the path to the repo.

This does eliminate some RawFilePath -> FilePath -> RawFilePath
conversions. And filepath-bytestring's </> is probably faster.
But I don't expect a major performance improvement from this.
This is mostly groundwork for making Annex.Location use RawFilePath,
which will allow for a conversion-free pipleline.

use ByteString for git config
The parser and looking up config keys in the map should both be faster
due to using ByteString.

I had hoped this would speed up startup time, but any improvement to
that was too small to measure. Seems worth keeping though.

Note that the parser breaks up the ByteString, but a config map ends up
pointing to the config as read, which is retained in memory until every
value from it is no longer used. This can change memory usage
patterns marginally, but won't affect git-annex.

wip RawFilePath 2x git-annex find speedup
Finally builds (oh the agoncy of making it build), but still very
unmergable, only Command.Find is included and lots of stuff is badly
hacked to make it compile.

Benchmarking vs master, this git-annex find is significantly faster!
Specifically:

	num files	old	new	speedup
	48500		4.77	3.73	28%
	12500		1.36	1.02	66%
	20		0.075	0.074	0% (so startup time is unchanged)

That's without really finishing the optimization. Things still to do:

* Eliminate all the fromRawFilePath, toRawFilePath, encodeBS,
  decodeBS conversions.
* Use versions of IO actions like getFileStatus that take a RawFilePath.
* Eliminate some Data.ByteString.Lazy.toStrict, which is a slow copy.
* Use ByteString for parsing git config to speed up startup.

It's likely several of those will speed up git-annex find further.
And other commands will certianly benefit even more.

81d402216d cache the serialization of a Key
This will speed up the common case where a Key is deserialized from
disk, but is then serialized to build eg, the path to the annex object.

Previously attempted in 4536c93bb2
and reverted in 96aba8eff7.
The problems mentioned in the latter commit are addressed now:

Read/Show of KeyData is backwards-compatible with Read/Show of Key from before
this change, so Types.Distribution will keep working.

The Eq instance is fixed.

Also, Key has smart constructors, avoiding needing to remember to update
the cached serialization.

Used git-annex benchmark:
  find is 7% faster
  whereis is 3% faster
  get when all files are already present is 5% faster
Generally, the benchmarks are running 0.1 seconds faster per 2000 files,
on a ram disk in my laptop.

git-lfs: remember urls, and autoenable remotes using known urls
* git-lfs: The url provided to initremote/enableremote will now be
  stored in the git-annex branch, allowing enableremote to be used without
  an url. initremote --sameas can be used to add additional urls.
* git-lfs: When there's a git remote with an url that's known to be
  used for git-lfs, automatically enable the special remote.

stop displaying rsync progress, and use git-annex's own progress display for local-to-local repo transfers
Reasons to do this include:

1. I've gotten pretty used to git-annex's own progress display, which is
   used for all transfers over ssh (except to old git-annex-shell),
   and for most special remote transfers. It's getting to seem weird to see
   the rsync progress display instead.
2. When -J was used, the rsync output could not be shown, and so there was
   no progress display. Now there will be.

Progress will also be displayed now when cp CoW is used. But I'd expect a CoW
copy to typically run so fast that the progress display will barely be
noticable.

add RemoteStateHandle
This solves the problem of sameas remotes trampling over per-remote
state. Used for:

* per-remote state, of course
* per-remote metadata, also of course
* per-remote content identifiers, because two remote implementations
  could in theory generate the same content identifier for two different
  peices of content

While chunk logs are per-remote data, they don't use this, because the
number and size of chunks stored is a common property across sameas
remotes.

External special remote had a complication, where it was theoretically
possible for a remote to send SETSTATE or GETSTATE during INITREMOTE or
EXPORTSUPPORTED. Since the uuid of the remote is typically generate in
Remote.setup, it would only be possible to pass a Maybe
RemoteStateHandle into it, and it would otherwise have to construct its
own. Rather than go that route, I decided to send an ERROR in this case.
It seems unlikely that any existing external special remote will be
affected. They would have to make up a git-annex key, and set state for
some reason during INITREMOTE. I can imagine such a hack, but it doesn't
seem worth complicating the code in such an ugly way to support it.

Unfortunately, both TestRemote and Annex.Import needed the Remote
to have a new field added that holds its RemoteStateHandle.

don't hide message when ensureInitialized fails 2019-08-27 12:38:47 -04:00
Joey Hess
bb18bbd426
consolidate calls to ensureInitialized
tryGitConfigRead may run ensureInitialized first, but when checkuuid = false,
that is skipped. So, make sure it's run before all onLocal actions.

ensureInitialized is inexpensive, so the extra call by tryGitConfigRead
is not a big deal. But since it was easy to do, I made it only be run
once by all calls to onLocal.

A few calls to onLocal didn't call ensureInitialized before. Notably,
the checkPresent action didn't, and does now.

That means that there's a guarantee that any necessary repo upgrades
will be run before the checkPresent action runs in the repo. Which is
important especially for the direct mode conversion, because without
that upgrade, the checkPresent action would need to support direct mode
still. Now I can remove the last bits of direct mode support in
Annex.Content without worrying that it will break accessing remotes
that have not been upgraded.

This does necessarily mean that checkPresent needs to write to the disk
when performing such a repo upgrade. The other remote actions already
did, so retrieval from a readonly remote that needed to be upgraded would
fail. Having checkPresent also fail doesn't seem like a large reversion,
especially since it already failed in the default case when checkuuid = true.

rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1207) [sender=3.1.3]

It seems that the first rsync actually transferred the file, but then for some
reason git-annex thinks it failed, so it retries. The second rsync then fails
because the first rsync copied the file mode over and so the file is not
writable now.

So, this fixes that problem, but leaves open the question of why git-annex
would think rsync failed when it wrote the file and didn't output any
error message. Possibly a bug in rsyncProgress that either hides an
error message, or somehow makes rsync unhappy?

CoW probing
Improved probing when CoW copies can be made between files on the same
drive. Now supports CoW between BTRFS subvolumes. And, falls back to rsync
instead of using cp when CoW won't work, eg copies between repos on the
same EXT4 filesystem.

Rather than trying cp --reflink=always for each file copied to a remote,
it's tried once and if it fails it falls back to using rsync thereafter
for the lifetime of the Remote object. That avoids overhead of calling cp
which while small, will add up over a large number of files.

fix nested exception bug
Fix reversion introduced in version 6.20180316 that caused git-annex to
stop processing files when unable to contact a ssh remote.

The bug was not in any of the changed lines, but this one in inAnnex:

P2PHelper.checkpresent (Ssh.runProto rmt connpool (cantCheck rmt) fallback) key

cantCheck throws an exception, but that parameter to runProto expects a
value, which it returns. So, inAnnex is returning a Bool containing an
exception. This defeats the usual checks for checkPresent throwing an
exception, crashing git-annex.

Fixed by making runProto take an `Annex a` instead of an `a`, so
passing cantCheck to it doesn't nest exceptions.

enforce retrievalSecurityPolicy
Leveraged the existing verification code by making it also check the

Also, prevented getViaTmp from running the download action at all when the
retrievalSecurityPolicy is going to prevent verifying and so storing it.

Added annex.security.allow-unverified-downloads. A per-remote version
would be nice to have too, but would need more plumbing, so KISS.
(Bill the Cat reference not too over the top I hope. The point is to
make this something the user reads the documentation for before using.)

A few calls to verifyKeyContent and getViaTmp, that don't
involve downloads from remotes, have RetrievalAllKeysSecure hard-coded.
It was also hard-coded for P2P.Annex and Command.RecvKey,
to match the values of the corresponding remotes.

A few things use retrieveKeyFile/retrieveKeyFileCheap without going
through getViaTmp.
* Command.Fsck when downloading content from a remote to verify it.
  That content does not get into the annex, so this is ok.
* Command.AddUrl when using a remote to download an url; this is new
  content being added, so this is ok.

add retrievalSecurityPolicy
This will be used to protect against CVE-2018-10859, where an encrypted
special remote is fed the wrong encrypted data, and so tricked into
decrypting something that the user encrypted with their gpg key and did
not store in git-annex.

It also protects against CVE-2018-10857, where a remote follows a http
redirect to a file:// url or to a local private web server. While that's
already been prevented in git-annex's own use of http, external special
remotes, hooks, etc use other http implementations and could still be
vulnerable.

The policy is not yet enforced, this commit only adds the appropriate
metadata to remotes.

removal of the rest of remoteGitConfig
In keyUrls, the GitConfig is used only by annexLocations
to support configured Differences. Since such configurations affect all
clones of a repository, the local repo's GitConfig must have the same
information as the remote's GitConfig would have. So, used getGitConfig
to get the local GitConfig, which is cached and so available cheaply.

That actually fixed a bug noone had ever noticed: keyUrls is
used for remotes accessed over http. The full git config of such a
remote is normally not available, so the remoteGitConfig that keyUrls
used would not have the necessary information in it.

In copyFromRemoteCheap', it uses gitAnnexLocation,
which does need the GitConfig of the remote repo itself in order to
check if it's crippled, supports symlinks, etc. So, made the
State include that GitConfig, cached. The use of gitAnnexLocation is
within a (not $ Git.repoIsUrl repo) guard, so it's local, and so
its git config will always be read and available.

(Note that gitAnnexLocation in turn calls annexLocations, so the
Differences config it uses in this case comes from the remote repo's
GitConfig and not from the local repo's GitConfig. As explained above
this is ok since they must have the same value.)

Not very happy with this mess of different GitConfigs not type-safe and
some read only sometimes etc. Very hairy. Think I got it this change
right. Test suite passes..

it's simply return.

Use http-conduit for url downloads by default, annex.web-options enables curl
* For url downloads, git-annex now defaults to using a http library,

  use curl. To use the .netrc file, run:

* git-annex no longer uses wget (and wget is no longer shipped with
  git-annex builds).

Note that curl is always run in silent mode, since the new API for
download has a MeterUpdate and doesn't make way for curl progress
output. It might be worth writing a parser for curl's progress output
to update the meter when using it, but I didn't bother with this edge
