Colin Walters ee5ecf33a5 lib: Define an alias OSTREE_REPO_MODE_ARCHIVE
For the old `OSTREE_REPO_MODE_ARCHIVE_Z2`.  Use it mostly tree
wide except for the repo finder tests (to avoid conflicting with
some outstanding PRs).

Just noted another user coming in some of those tests and wanted to do a
cleanup.

Philip Withnall 64b23fd089 lib/repo: Add ostree_repo_hash() and tests
Add a hash function for OstreeRepo instances, which relies on the repo

Colin Walters ae075d23e3 lib/repo: Use correct name for tmpdir lockfile
Such an evil bug 🙈. I was just reading an strace trying to figure out what was
going on, and noticed we had the `XXXXXX` in the lockfile name. It was only
after that I realized that that this might *be* the cause of the skopeo issue.

This is another case where we definitely need more test coverage of things that
actually use the API multiple times in process; might look at dusting off the
work for the rpm-ostree test.

Colin Walters 160864d557 lib: Move bareuseronly verification into commit/core
Conceptually `ostree-repo-pull.c` should be be written using
just public APIs; we theoretically support building without HTTP
for people who just want to use the object store portion and
do their own fetching.

We have some nontrivial behaviors in the pull layer though; one
of those is the "bareuseronly" verification.  Make a new internal
API that accepts flags, move it into `commit.c`.  This
is prep for further work in changing object import to support
reflinks.

Jonathan Lebon d4c7093e37 rofiles-fuse: also pass mode for O_RDONLY
In the `O_RDONLY` case, we were calling `openat` without a mode
argument. However, it's perfectly legal (albeit unusual) to do
`open(O_RDONLY|O_CREAT)`. One such application that makes use of this is
`flock(1)`.

This was actually caught by `_FORTIFY_SOURCE=2`, and once we run
`rofiles-fuse` with `-f`, the message is clear:

```
*** invalid openat64 call: O_CREAT or O_TMPFILE without mode ***:
rofiles-fuse terminated
======= Backtrace: =========
/lib64/libc.so.6(+0x7c8dc)[0x7f36d9f188dc]

/lib64/libc.so.6(+0x10019a)[0x7f36d9f9c19a]
rofiles-fuse[0x401768]

```

Without `_FORTIFY_SOURCE`, the file gets created, but its mode is
completely random.

Colin Walters 5c4f26bd65 lib/pull: Wait for pending ops to complete on error
I saw in a stack trace that the main thread was calling `exit()` even while
worker threads were alive and doing sha256/write/fsync etc. for objects.

The stack trace was a SEGV as the main thread was calling into library
`atexit()` handlers and we were a liblz4 destructor:

```
 #0  0x00007f2db790f8d4 _fini (liblz4.so.1)
 #1  0x00007f2dbbae1c68 __run_exit_handlers (libc.so.6)
```

(Why that library has a destructor I don't know offhand, can't find
 it in the source in a quick look)

Anyways, global library destructors and worker threads continuing simply don't
mix. Let's wait for our outstanding operations before we exit. This is also a
good idea for projects using libostree as a shared library, as we don't want
worker threads outliving operations.

Our existing pull corruption tests exercise coverage here.

I added a new `caught-error` status boolean to the progress API, and use it the
commandline to tell the user that we're waiting for outstanding ops.

Philip Withnall 15247641d9 lib/repo-finder-mount: Change the schema for finding repos on volumes
See issue #1174 for the rationale behind this. In summary:
 • It required two lists of collection–refs to be maintained: one in the
   repository, and one pointing to the repository.
 • It didn’t automatically work for live USBs of OSs based on OSTree
   (where there’s always a repository at /ostree/repo).
 • It was unnecessarily complex.

The new scheme allows a list of repositories to be searched, but without
needing a layer of indirection through their collection–refs. It adds
/ostree/repo and /.ostree/repo as well-known repository locations which
are always checked on a mounted volume (if they exist).

Update the unit tests accordingly.

Colin Walters 0488b4870e lib/pull: Drop partial fetch code from libsoup backend
Doing this in prep for libglnx tmpdir porting, but I think we should also do
this because the partial fetch code IMO was never fully baked; among other
things it was never integrated into the scheme we came up with for "boot id
sync" that we use for complete/staged objects.

There's a lot of complexity here that while we have some coverage for, I think
we need to refocus on the core functionality. The libcurl backend doesn't have
an equivalent to this today.

In particular for small objects, this is simply overly complex. The downside is
clearly for large objects like FAH's 61MB initramfs; not being able to resume
fetches of those is unfortunate.

In practice though, I think most people should be using deltas, and we need to
make sure deltas work for large objects anyways.

Further ultimately the peer-to-peer work should help a lot for people
with truly unreliable connections.

Colin Walters c32f234e9a lib/checkout: Do UNION_FILES via atomic renameat()
I was looking at fixing an `rpm-ostree livefs` bug where we need to replace
`/usr/lib/passwd`. It's obviously bad if that temporarily disappears 😉. My plan
is to do a subpath checkout of just `/usr/lib/{passwd,group}`.

Make this atomic (i.e. file always exists) by changing the logic to create a
temporary link in repo/tmp, then rename() it into place.

A bonus here is we kill one of the very few (only?) non-error-cleanup i.e.
"non-linear" `goto`s in the ostree codebase.

Dan Nicholson adac42b6ef repo: Add add-remotes-config-dir option
This option allows a repo to explicitly opt out of adding new remotes in
a remotes configuration directory. This currently defaults to true for
system repos and false for non-system repos to maintain legacy behavior
that non-system repos don't add remotes in a configuration directory.
That would be problematic for flatpak, which specifies a remotes config
dir but adds remotes in ways that are incompatible with it.

So, what this really does is allow system repos to control whether they
want to add remotes in the config dir or not. That's important if your
flatpak repo is the system repo like at Endless.

Alexander Larsson 08eaf66827 rofiles-fuse: Fix lchown() and hardlink verification for symlinks
If you lchown("symlink") then we were incorrectly trying to chown the
symlink target, rather than the symlink itself. In particular, this cause
cp -a to fail for a broken symlink. Additionally, it was using the
symlink target when verifying writability, rather than the symlink
itself.

To fix this, we need pass AT_SYMLINK_NOFOLLOW in these cases.

In general, the kernel itself will always resolve any symlinks for us
before calling into the fuse backend, so we should really never do any
symlink following in the fuse fs itself. So, we pro-actively add
NOFOLLOW flags to a few other places:

 truncate:
      In reality this will never be hit, because
      the kernel will resolve symlinks before calling us.
 access:
      It seems the current fuse implementation never calls this
      (faccessat w/AT_SYMLINK_NOFOLLOW never reaches the fuse fs)
      but if this ever is implemented this is the correct behaviour.

We would ideally do `chmod` but this is not implemented on current kernels.
Because we're not multi-threaded, this is OK anyways.

Further, our write verification wasn't correctly handling the case of hardlinked
symlinks, which can occur for `bare` checkouts but *not* `bare-user` which the
tests were using. Change to `bare` mode to verify that.

Also, AFAICS there was no test coverage of `generate_deployment_refs()`; I tried

Jonathan Lebon 12114ce382 commit: filter out selinux label before commit
The new --selinux-policy added in [0] exposed a subtle issue in the way
we handle labeling during commit. The CI system in rpm-ostree hit this
when trying to make use of it[1].

Basically, because of the way we use a GVariant to represent xattrs, if
a file to be committed already has an SELinux label, the xattr object
ends up with *two* label entries. This of course throws off fsck later
on, since the checksum will have gone over both entries, even though the
on-disk file will only have a single label (in which the second entry
wins).

I confirmed that the `fsck` added in the installed test fails without
the rest of this patch.

Colin Walters 138c4d7aae libarchive: Add support for translating paths during commit
For rpm-ostree, I want to move RPM files in `/boot` to `/usr/lib/ostree-boot`.
This is currently impossible without forking the libarchive code.  Supporting
this is pretty straightforward; we already had pathname translation in
the libarchive code, we just need to expose it as an option.

On the command line side, I chose to wrap this as a regexp. That should be good
enough for a lot of use cases; sophisticated users should as always be making
use of the API. Note that this required some new `#ifdef LIBARCHIVE` bits to use
the new API. Following previous patterns here, we use the new API only if a
relevant option is enabled, ensuring unit test coverage of both paths.

For the test cases, I ended up changing the accounting to avoid having to
multiply the test count.

Jonathan Lebon 9342be6e34 ostree-sysroot: make simple_write_deployment smarter
This is a follow-up to https://github.com/ostreedev/ostree/pull/1097.
We make simple_write_deployment smart enough so that it can be used for
rpm-ostree's purposes. This is mostly an upstreaming of logic that
already existed there.

Notably we correctly append NOT_DEFAULT deployments *after* the booted
deployment and we now support RETAIN_PENDING and RETAIN_ROLLBACK flags
to have more granularity on deployment pruning.

Expose these new flags on the CLI using new options (as well as expose
the previously existing NOT_DEFAULT flag as --not-as-default).

is always the topmost one. Though I did check that it worked in a VM.

Matthew Leeds 7ed881baa7 lib/repo-refs: Include remote refs when using collections
When working with collections it can be useful to see remote refs rather
than just local and mirrored ones. This commit changes the "ostree refs
-c" output to include remote refs, and includes remote refs with
collection IDs in summary file generation as well. The former behavior
is consistent with how "ostree refs" works, and the latter behavior is
useful in facilitating P2P updates even when mirrors haven't been
configured.

To accomplish this, OstreeRepoListRefsExtFlags was extended with an
EXCLUDE_REMOTES flag. This was done rather than an INCLUDE_REMOTES flag
so that existing calls to ostree_repo_list_refs_ext continue to have the
same behavior. This flag was added to ostree_repo_list_collection_refs
(which is an experimental API break).

Also, add unit tests for the "refs -c" and summary file behavior, and
update relevant tests.

Follow up to <https://github.com/ostreedev/ostree/pull/1079>; I was working on
the rpm-ostree updates for this, and I think it's more consistent if we have
`.img` here, since that's a closer match to the "remove $kver" that results in
`vmlinuz`. Also just best practice to have file suffix types where they make
sense.

The astute reader might notice this sneaks in a change where we'd crash if the
legacy bootdir didn't have an initramfs...yeah, should probably have test
coverage of that.

Colin Walters 3ab0d5e664 lib/sysroot: Support /usr/lib/modules/$kver for kernel/initramfs
This is the new Fedora kernel standard layout; it has the advantage
of being in `/usr` like `/usr/lib/ostree-boot`, but it's not OSTree
specific.

Further, I think in practice forcing tree builders to compute the checksum is an
annoying stumbling block; since we already switched to e.g. computing checksums
always when doing pulls, the cost of doing another checksum for the
kernel/initramfs is tiny. The "bootcsum" becomes more of an internal
implementation detail.

Now, there is a transition; my current thought for this is that rpm-ostree will
change to default to injecting into both `/usr/lib/ostree-boot` and
`/usr/lib/modules`, and stop doing `/boot`, then maybe next year say we drop the
`/usr/lib/ostree-boot` by default.

A twist here is that the default Fedora kernel RPM layout (and what's in
rpm-ostree today) includes a kernel but *not* an initramfs in
`/usr/lib/modules`. If we looked only there, we'd just find the kernel. So we
need to look in both, and then special case this - pick the legacy layout if we
have `/usr/lib/modules` but not an initramfs.

While here, rework the code to have an `OstreeKernelLayout` struct which makes
dealing with all of the variables nicer.

Philip Withnall 8c148eb7e1 lib/repo-finder: Emit gpg-verify-summary=false in dynamic remote config
When returning results from finding repos, set gpg-verify-summary=false
in their configs, since any pulls from such remotes will necessarily
involve collection IDs, and hence should be using the unsigned summary
support. In the intended deployment mode for P2P transmission of OSTree
refs, summaries *cannot* be signed, so setting gpg-verify-summary=true
would cause all the pulls to fail.

The unsigned summary support is the move of repository metadata from
the summary file (not spliceable) to the well-known ostree-metadata ref
(spliceable, as it can exist for multiple collection IDs in the same
repository).

Colin Walters 8642ef5ab3 lib/deploy: Use a FIFREEZE/FITHAW cycle for /boot
See: http://marc.info/?l=linux-fsdevel&m=149520244919284&w=2

XFS doesn't flush the journal on `syncfs()`. GRUB doesn't know how to follow the
XFS journal, so if the filesystem is in a dirty state (possible with xfs
`/boot`, extremely likely with `/`, if the journaled data includes content for
`/boot`, the system may be unbootable if a system crash occurs.

Fix this by doing a `FIFREEZE`+`FITHAW` cycle.  Now, most people
probably would have replaced the `syncfs()` invocation with those two
ioctls.  But this would have become (I believe) the *only* place in
libostree where we weren't safe against interruption.  The failure
mode would be ugly; nothing else would be able to write to the filesystem
until manual intervention.

The real fix here I think is to land an atomic `FIFREEZETHAW` ioctl
in the kernel.  I might try a patch.

In the meantime though, let's jump through some hoops and set up
a "watchdog" child process that acts as a fallback unfreezer.

Colin Walters e0346c1494 Add a notion of "physical" sysroot, use for remote writing
(Note this PR was reverted in <https://github.com/ostreedev/ostree/pull/902>;
 this version should be better)

Using `${sysroot}` to mean the physical storage root: We don't want to write to
`${sysroot}/etc/ostree/remotes.d`, since nothing will read it, and really
`${sysroot}` should just have `/ostree` (ideally). Today the Anaconda rpmostree
code ends up writing there. Fix this by adding a notion of "physical" sysroot.
We determine whether the path is physical by checking for `/sysroot`, which
exists in deployment roots (and there shouldn't be a `${sysroot}/sysroot`).

In order to unit test this, I added a `--sysroot` argument to `remote add`.
However, doing this better would require reworking the command line parsing for
the `remote` argument to support specifying `--repo` or `--sysroot`, and I
didn't quite want to do that yet in this patch.

This second iteration of this patch fixes the bug we hit the first time;
embarassingly enough I broke `ostree remote list` finding system remotes.
The fix is to have `ostree_repo_open()` figure out whether it's the same
as `/ostree/repo` for now.

Down the line...we might consider having the `ostree remote` command line itself
instatiate an `OstreeSysroot` by default, but this maximizes compatibility; we
just have to pay a small cost that `ostree` usage outside of that case like
`ostree static-delta` in a releng Jenkins job or whatever will do this `stat()`
too.

Colin Walters 8b1f1c4428 lib/pull: Do local content imports async too
This came up in <https://github.com/ostreedev/ostree/pull/982>; when
we added more direct local importing, we did it synchronously.

This was actually quite a regression when doing local pulls between different
modes; in particular between a bare mode and `archive`, as we were suddenly
doing gzip {de,}compression in the main thread.

Down the line actually...a simpler fix is probably to change things so that the
local path is really only used when we know we can hardlink; everything else
would go though the fetcher codepath but with `file://`.

But this isn't a lot more code, and the speed/interactivity win is large.

Note we're only doing content async with this patch. We could do metadata as
well; we have the object already local. But the metadata code path is messier,
and metadata objects are smaller.

Another area where this comes up is that in e.g. Fedora releng, most operations
talk to a NetApp via NFS. So this has the classic network filesystem problem
that operations that are normally cheap like `stat()` can actually have
nontrivial latency. Doing as much as possible in threads is better there too.

Philip Withnall acb14648d7 lib/repo: Add OSTREE_REPO_METADATA_REF as a well-known metadata store
As discussed in https://github.com/ostreedev/ostree/pull/946, the

additional metadata for the repository needs to move elsewhere in order
to remain signed. Introduce OSTREE_REPO_METADATA_REF as the well-known

Philip Withnall 7d57459e83 lib/repo-commit: Fix types of content size cache entries
Use goffset rather than gsize for file sizes. More importantly, get the
unpacked_size from g_file_info_get_size() (goffset) rather than from the
splice return value, which has type gssize.

This will make a difference on 32-bit systems, where goffset is defined
as off64_t, but gsize is 32 bits.

Colin Walters 9d941dcebb checkout: Don't set dir mtime to 0 when doing a force copy checkout
When we [switched to using checkout + force_copy](e8efd1c8dc),
a side effect that went unnoticed at the time is that we started
setting directory mtimes to zero.

See the below bug where we long ago set the file times to zero, which got fixed,
so let's not regress things by setting the directory times to zero either. (Even
though AFAICS GNU tar doesn't complain about those)

This semantic is somewhat "overloaded" onto `force_copy`, but it avoids adding
yet another boolean; we don't have that many reserved boolean slots left. I
can't really think of many good use cases for `force_copy` *other* than the
`/etc` merge anyways.

Colin Walters 3234295324 pull: Cleanly error when doing local pulls of remote-prefixed refs
In the storage PR I was trying to do a `pull-local` of the whole
`/ostree/repo` on the system, which ended up triggering a `g_critical()`
in the collections code, since we tried to parse a remote-prefixed ref
`fedora:fedora/26/x86_64/atomic-host` as a ref.

I'm not sure offhand what our behavior in this case *should* be.  I
think git only clones local refs, but I need to check.

This corner case arises only with `pull-local`.  But in any case,
while we were previously saying this is programmer error, since it's
so easy to pass various unchecked input into the pull machinery,
make invalid refs an explicit error.

Colin Walters 3348baf6eb lib/commit: Ensure bare-user objects are always user-readable
Some of the Jenkins jobs for Fedora Atomic Host broke after updating
to 2017.7, and it turns out that we regressed handling unreadable
files in `bare-user` mode.  An example of this is `/etc/shadow`, which
ends up in the ostree-as-host content as `/usr/etc/shadow`.

Now there are better fixes here; we should probably delete it and create it
during the config merge if it doesn't exist.  In general, having secret files in
ostree really isn't supported, so it doesn't make sense to include them.

But let's fix this regression - when operating as an unprivileged user we don't
have `CAP_DAC_OVERRIDE` and hence will fail to open un-user-readable objects.

(We still preserve the actual `0` mode of course in the xattr and will
 apply it in `bare`)

However, for testing a change to `bare-user` handling around *unreadable*

to write that into a repo in the test suite.

I'm not actually aware of a non-test-suite use case for this; a more

this. But we need it for tests at least.

it does consume the *path* but not the fd.  In the non-delta path
things were fine since we used the autocleanup.

hence leaked the fd. Fix this by making the commit API actually consume the

Colin Walters 4273e670ea Add "pull --localcache-repo"
This is a lot like `git clone --reference`, but we chose "localcache" as the
term "reference" is already used.

The main use case I'm targeting this for is the Fedora Atomic Host installer
case where we embed the repo content in the installer, but we may want to
kickstart and download newer content. There, while we want to get a newer ref,
we can still use the local repo as an object cache, since we have it sitting
there in memory anyways.

Another case is where one has a host ostree (say e.g. Fedora Atomic
Workstation), and one wants to create a local archive mirror of FAH. Then one
can use `pull --reference /ostree/repo` and pull the common objects (e.g.
contents of `bash.rpm` etc.)

Colin Walters 5776d5dcc0 Port to GLnxTmpfile
There's lots of mechanically replacing `OtTmpFile` with `GLnxTmpfile`;
the biggest changes are in the commit path.  Symlink commits are now
very clearly separated from regular files.  Symlinks are `OtCleanupUnlinkat`,
and regular files are `GLnxTmpfile`.

The commit codepath separates those as `_ostree_repo_commit_path_final()` and
`_ostree_repo_commit_tmpf_final()`. A nice aspect of all of this is that they
both *consume* the temporary on success. This avoids an extra spurious
`unlink()` call.

One of the biggest bits of code motion is in `commit_loose_regfile_object()`,
which no longer needs to care about symlinks. For the most parth though it's
just removing conditionals.

The implementation (including its parameter choices and hash functions)
will become a protocol detail in future, so must not be changed so that
its output is bitwise incompatible between OSTree versions.

Unit tests are included.

Philip Withnall ae335f24dc lib/repo-finder: Add mount based OstreeRepoFinder implementation
This is a basic implementation of OstreeRepoFinder which resolves ref
names to remote URIs by looking for them on any currently mounted
removable storage volumes. The idea is to support OS and app updates via
USB stick.

Unit tests are included.

This bumps libostree’s maximum GLib dependency from 2.44 to 2.50 for
g_drive_is_removable(). If GLib 2.50 is not available, the call which
needs it will be omitted and the OstreeRepoFinderMount implementation
will scan all volumes (not just removable ones); this is a performance
hit, but not a functionality hit.

Philip Withnall 292230301d lib/repo-finder: Add basic support for finding remote URIs by ref name
Add an initial OstreeRepoFinder interface (but no implementations),
which will find remote URIs by ref names and collection IDs, the
combination of which is globally unique.

The new API is used in a new ostree_repo_find_updates() function, which
resolves a list of ref names to update into a set of remote URIs to pull
them from, which can be treated as mirrors. It is an attempt to
generalise resolution of the URIs to pull from, and to generalise
determination of the order and parallelisation which they should be
downloaded from in.

Colin Walters 612c8a5fa8 lib/repo: More cleanup of load_file() internals
This is followon work from previous cleanups.  Basically
`stat_bare_content_object()` was the `fstatat()` logic
and `ostree_repo_read_bare_fd()` was the `openat()` implementation;
they duplicated some bits to find the object in staging, recurse
into parent etc.

Further, I wanted an internal-only version of this API which didn't allocate
`GFileInfo`/`GInputStream` but used a plain `fd` and `struct stat` to avoid
mallocs.

The end version here I think looks a lot nicer, since we deduplicate the various
`open()` calls in the different cases for example.

Colin Walters 74e3581ed6 lib/repo: Support hardlink conversions from bare-user to bu-only
Thinking about the problem of flatpak converting from `bare-user` to `bare-user-only`
"in place" by creating a new repo and doing a `pull-local`, I realized
that we can optimize this process by doing hardlinks for both metadata
and regular files.  The repo formats are *almost* compatible, the
exception being symlinks.

An earlier patch caused us to do hardlinks for metadata, this patch takes things
to the next step and special cases this specific conversion. In this case we
need to parse the source object to determine whether or not it's a symlink.

that's quite useful thing to do. Our documentation encourages converting to/from
those repo modes locally for build systems.

Before this, if one had repos of matching mode but different owners,
which could happen if one e.g. makes a `bare` non-root repo in
`/ostree/deploy/$stateroot/var/tmp`, every time we tried to call `linkat()`
we'd get `EPERM` and fall back to a copy.

Fix this by saving the repo owner uid, and avoid trying to call `linkat()` if we
know it's going to fail. Of course most commonly in this scenario we'll
immediately fail trying to `chown` the files to `0`, but this is prep for a
future patch to improve `bare-user` → `bare-user-only` imports where we'll be a
bit more sophisticated.

See https://github.com/ostreedev/ostree/pull/909 for more information on the
rationale. Basically there's no reason for flatpak (which uses `bare-user-only`)
to have world-writable dirs. Particularly with the presence of the system
helper.

An approach I considered instead was to parse and validate directory metadata
objects at commit time. We still may do that in addition; for file objects we *had*
to do it that way because the actual files would be laid down suid.  But directories
live only as inert `.dirmeta` objects until we do a checkout (i.e. `mkdir()`), so
we can solve the problem at checkout time.

Colin Walters 0c4b3a2b6d Canonicalize bare-user-only perms with 0755 mask
For the flatpak use case where bare-user-only was introduced, we actually
don't want to support s{u,g} id files in particular.

Actually, I can't think of a reason to have anything outside of the
`0755 i.e. (u=rwx,g=rx,o=rx)` mask, so that's what we do here.

This will have the effect of treating existing `bare-user-only` repositories as
corrupted if they have files outside of that mask, but I think we should do this
now; most of the flatpak users will still be on `bare-user`, and we haven't
changed the semantics of that mode yet.

Note that in this patch we will also *reject* file content that doesn't
match this.  This is somewhat asymmetric, since we aren't similarly rejecting
e.g. directory metadata.  But, this will close off the biggest source
of the problem for flatpak (setuid binaries).

Owen W. Taylor 25696b3fb0 lib/repo: Don't copy xattrs when manipulating the GPG keyring
Copying xattrs when manipulating the GPG keyring for a repository
causes errors when the underlying filesystem doesn't support writing
xattrs - overlayfs is a common example. It also causes the selinux
attributes of the keyring files to be copied from the temporary
location instead of properly inherited from the destination directory
(ending up, for example, as unconfined_u:object_r:user_tmp_t:s0, rather
than unconfined_u:object_r:data_home_t:s0)

When falling back to copying, we previously would only chmod checked out

Colin Walters cad42d9601 Revert "Add a notion of "physical" sysroot, use for remote writing"
This reverts commit 1eff3e8343. There
are a few issues with it.  It's not a critical thing for now, so
let's ugly up the git history and revisit when we have time to
debug it and add more tests.

Besides the below issue, I noticed that the simple `ostree remote add`
now writes to `/ostree/repo/config` because we *aren't* using the
`--sysroot` argument.

Colin Walters f4f1330789 repo/commit: Split up metadata/content commit paths
There was a lot of conditionals inside `write_object()` differentating
between metadata/content, and then for content, on the different repo
types.  Further, in the metadata path since the logic is simpler, can
present a non-streaming API, and further use `OtTmpfile`, etc.

Splitting them up helps drop a lot of conditionals. We introduce a small
`CleanupUnlinkat` that allows us to fully convert to the new code style in both
functions.

This itself is still prep for fully switching to `GLnxTmpfile`.

Colin Walters 22b1234f52 repo/commit: Dedup metadata writing API implementations
First, the streaming metadata API is pretty dumb, since metadata
should be small.  Really we should have supported a `GBytes`
version.  Currently, this API *is* used when we do local pulls,
so this commit has test coverage.  However, I plan to change
the object import to avoid using this.  But that's fine, since
I can't think of why someone would use this API.

Next, the only difference between `ostree_repo_write_metadata()` and
`ostree_repo_write_metadata_trusted()` is whether or not we pass
an output checksum; so just dedup the implementations.

Also while I'm here break out the input length validation and do
it early in the streaming case.

Colin Walters 1eff3e8343 Add a notion of "physical" sysroot, use for remote writing
Using `${sysroot}` to mean the physical storage root: We don't want to write to
`${sysroot}/etc/ostree/remotes.d`, since nothing will read it, and really
`${sysroot}` should just have `/ostree` (ideally). Today the Anaconda rpmostree
code ends up writing there. Fix this by adding a notion of "physical" sysroot.
We determine whether the path is physical by checking for `/sysroot`, which
exists in deployment roots (and there shouldn't be a `${sysroot}/sysroot`).

In order to unit test this, I added a `--sysroot` argument to `remote add`.
However, doing this better would require reworking the command line parsing for
the `remote` argument to support specifying `--repo` or `--sysroot`, and I
didn't quite want to do that yet in this patch.

Alexander Larsson be0c02d4f9 fetcher: Send Accept-Encoding: gzip when downloading summary
The summary file can get large, but it compresses well (something
which is not true of other files in the ostree repo which are
already compressed). By sending Accept-Encoding: gzip (and
handling the compressed results) we send a lot less data.

I set up the flathub repo (http://flathub.org/repo) to enable
gzip for the summary file (only), and the result is that the
331514 byte large summary was transferred in 122889 bytes.
On my (fast) network this decreased the time i took to do
"flatpak remote-ls flathub" by about 100msec.

Daniel Drake c1ed9a15c1 Allow commits to mark refs as EOL, replaced by others
A commit can now include a "ostree.endoflife-rebase" metadata key
pointing to a new ref.

When updating, the sysroot upgrader will see this and proceed to
pull and deploy the new ref instead. The origin file in the new
deployment will point to the new ref.

This functionality is planned to be used in Endless OS. We will create
a lesser tested branch for brand new, cutting edge hardware support,
and ship that on hardware platforms that require the latest drivers.
However, once our slower-moving official release is later updated to
support the new hardware, we will use this functionality to migrate
those bleeding-edge users over to the official release.
