Colin Walters 70e5489258 lib: Add a helper for mmap->bytes with openat(), use it in repo
This kills another GSystem consumer...I think down the line I'd like
to do something like "detect whether file is > 1k if so, mmap,
otherwise just readall()" so we can use this helper in more places.

Colin Walters 3a03a35071 lib: Add `_ALLOW_NOENT` flag to internal variant mapping API
We have a lot of "allow_noent" type wrapper functions since
a common pattern is to allow files to not exist, but still
throw cleanly on other issues.

This is another instance of that, and cleans up duplicated error
handling code.

Part of this is prep for moving away from `GFile` consumers.

Colin Walters c148631a98 lib: Drop GFile variant mapping API for fd-relative
In addition to generic fd relative porting,
this is a necessary preparatory step for libglnx porting, because
when I tried to use `g_mapped_file_new` I hit an issue with
it using a different error domain from GIO.

Thankfully libglnx consistently uses the GIO error domain, and here
we're now using it for the `open()` call.

Bug 765429 said that not having a time estimate can be annoying

Krzesimir Nowak 862e6ecdcc libostree: Variant-related leak plugs and fixes
This tries to avoid leaking GVariantBuilders and GVariants in some
situations. The leaks were usually happening when some error occurred
or because of unclear variant ownership situation.

The former is mostly about making sure that g_variant_builder_clear is
called on builders that didn't finish their variant building process.

The latter is surely more work - sometimes the result of
g_variant_builder_end() should not be passed directly to a function,
but rather stored in a g_autoptr(GVariant), sunk and then passed to a
function. IMO, with an advent of g_autoptr, GVariants should be always
sunk instead of relying on some receiver function sinking it. This
would make an easy-to-follow policy of always sinking your
variants. Functions could then assume that the passed variant is
already sunk. These leaks are still happenning in commands, but they
are less harmful, since that code will not be used by some daemon as a
library routine.

Jonathan Lebon 65e7969b0b OstreeRepo: add extensions directory
It's very useful for third-party applications to have someplace to store
their data guaranteed to be on the same device as the repo (thus
ensuring hardlinks) while still being shielded away from any of OSTree's
timely garbage collections.

We create a new "extensions/" subdirectory where apps can include
whatever they wish in "extensions/myapp/". This subdirectory is
completely unmanaged by ostree.

NB: I didn't bother making it a member of the OstreeRepo proper since we
don't really use it for anything else yet.

To GLnxConsoleRef.  There were some subtleties here, for example we
used to reference `GSConsole` inside the progress changed function,
which at first seems like an ABI hazard, because e.g. rpm-ostree or
xdg-app could still be passing a `GSConsole` instance there.  Luckily,
it turns out to be compatible to just start calling libglnx here.

Another issue was that due to libglnx's use of the cleanup function,
we needed to ensure we always called `ostree_async_progress_finish()`
*before* the cleanup function was invoked.

Colin Walters 42c60effbe pull: Support specifying exact commit to pull via branch@commit
I don't know why we didn't do this a long time ago.  This extends the
pull API to allow grabbing a specific commit, and will set the branch
to it.  There's some support for this in the deploy engine, but there
are a lot of reasons to support it for raw pulls (such as subset
mirroring cases).

In fact I'm thinking we should also have the override-version logic
here too.

NOTE: One thing I debated here is inventing a new syntax on the
command line.  Git doesn't seem to have this functionality (probably
because it'd be rarely used). The '@' character at least doesn't
conflict with anything.

Anyways, I wanted this for some other test cases.  Without this,
writing tests that go between different commits is more awkward as one
must generate the content in one repo, then pull downstream, then
generate more content, then pull again.  But now I can just keep track
of commit IDs and do exactly what I want without synchronizing the
tests.

Colin Walters dc9239dd7b sysroot: Don't individually fsync dirs in checkout, rely on syncfs
Originally, a lot of the `fsync()` calls here were added for the
wrong reason - I was chasing a bug that ended up being the extlinux
bootloader not parsing 64 bit ext4 filesystems.  But since it looked
like corruption, I tried adding a lot more `fsync()` calls.

All we should have to do is use `syncfs()`.  If that doesn't work,
it's a kernel bug.

I'm making this change because skipping the individual fsyncs can be a
major performance win - it's easier for the FS to optimize, we do more
in parallel, etc.

Colin Walters 84fe2ffb2b pull: Go back to using one main context
xdg-app was hanging for me with v2015.8, but worked with v2015.7.
I narrowed things down to the GMainLoop/context commit, in which
we started pushing a temporary main context for synchronous
requests internally.

That's never really going to work with libsoup - there needs
to be a single main context which works on the socket.  Furthermore,
clients couldn't get progress messages that way.

For *other* internal uses where we added APIs that talk to the remote
repo, we cleanly push a temporary main context.

(Note that I kind of snuck in a change here around the GError handling
 in pulls that isn't strictly related but came up in testing)
2015-09-01 14:39:24 -04:00
Colin Walters 9f3d586993 pull: Stop using GMainLoop
First of all, what we were doing with having GMainLoop in the internal
APIs is wrong.  Synchronous APIs should always create their own main
context and not iterate the caller's.  Doing the latter creates
potential for evil reentrancy issues.  Sync API should block, async
API is for not blocking.

Now that's out of the way, fix the pull code to do the clean

```
while (termination_condition (state))
  g_main_context_iteration (mainctx, TRUE);
```

model for looping.  This is a lot easier to understand and ultimately
more reliable than having other code call `g_main_loop_quit()`, as the
loop condition is in exactly one place.

We can also remove the idle source which only fired once.

Note we have to add a hack here to discard the synchronous session and
create a new one which we only use async.

Colin Walters efcdf4c3f8 repo: Bump mtime any time we write a ref
External daemons like rpm-ostree want push notification any time a
change is made by an external entity.  inotify provides notification,
but a problem is there's no easy way to monitor all of the refs.

In the past, there has been discussion of opt-in recursive timestamps:
https://lkml.org/lkml/2013/4/5/307

But in today's world, let's just bump the mtime on the repo itself, as
a central inotify point.

Colin Walters 5becd5ccad Teach fsck about partial commits
An OSTree user noticed that `ostree fsck` would produce `missing
object` errors in the case of interrupted pulls.

It's possible to do e.g. `ostree pull --subpath=/usr/share/rpm ...`,
which gets you just that portion of the commit.  The use case for this
was being able to see what changes would appear in an update before
actually downloading all of it.

(I think this would be better covered by static deltas, but those
 aren't final yet, and `--subpath` predates it)

Further, `.commitpartial` is used as a successor to the `transaction`
symlink for more precise knowledge in the case where a pull was
interrupted that we needed to resume scanning.

So it makes sense for `ostree fsck` to be aware of it.

return this object for commit signature verification so it can be utilized
at the CLI layer (and possibly by other programs).

Matthew Barnes c2b01adbf0 OstreeGpgVerifier: Take the signature as a GBytes
The signature data is in memory to begin with, so there's no need to

Also, because the GPGME multi-keyring workaround is somewhat expensive
to setup and teardown, concatenate all signatures into a single GBytes
so _ostree_gpg_verifier_check_signature() is only called once.  We're
currently only looking for one valid signature anyway.

This follows up from the previous commit; now that pull knows how to

As part of this:
 - pull() can also accept a file:/// URI instead
   of a remote name (since pull local supports anonymous pulls)
 - pull() knows an "override-remote-name" option, since pull-local
   supported writing a ref out even if there wasn't a remote with
   that name

Matthew Barnes 17b9e399b8 repo: Add an internal struct to manage remotes
OstreeRemote is a reference-counted struct that encompasses data about a
remote, whether read from a configuration file or created explicitly via
ostree_repo_remote_add().

OstreeRemotes are held in an internal table indexed by remote name.
This solves some problems caused by merging system-wide remote data into
the OstreeRepo's internal config key file.

Alexander Larsson 47c612e5a0 Support for "bare-user" repo format
This format is pretty much the same as the "bare" format, except the
file ownership and xattrs is not stored in the actual filesystem object, but
rather on the side in a user xattr. This means two things:

1) An unprivileged user can store such a repo independent of the types
   of files in it or their xattrs. And you can later (as root)
   reconstruct the real filesystem tree with ownership. Although you
   can't do that using hardlink-sharing. This also means ostree
   fsck does a full verification.

2) Such a repository can be checked out with user-mode (checkout -U)
   as an unprivileged user using hardlinks for space sharing.

Additionally, symlinks are stored as regular files (with the content
being the symlink target) because user xattrs are not supported on
symlinks. We know at checkout time if the file is a symlink because
the original st_mode is stored in the xattr metadata.

target repository be owned by a uid other than root.

This patch makes it Just Work by chowning the file content to match.

Colin Walters f8f5da219e Add repository "summary" file and metalink support
For Fedora and potentially other distributions which use globally
distributed mirrors, metalink is a popular solution to redirect
clients to a dynamic set of mirrors.

In order to make metalink work though, it needs *one* file which can
be checksummed.  (Well, potentially we could explode all refs into the
metalink.xml, but that would be a lot more invasive, and a bit weird
as we'd end up checksumming the checksum file).

This commit adds a new command:

$ ostree summary -u

To regenerate the summary file.  Can only be run by one process at a
time.

After that's done, the metalink can be generated based on it, and the
client fetch code will parse and load it.

Anne LoVerso fd56952d6b ostree-repo-resolve-rev: Add function to accept a partial checksum
This patch adds a function that will parse a partial checksum when
resolving a refspec.  If the inputted refspec matches a truncated
existing checksum, it will return that checksum to be parsed.  If
multiple truncated checksums match the partial refspec, it is not
unique and will return false.  This addition is inspired by the same
functionality in Docker, which allows a user to reference a specific
commit without typing the entire checksum.

partial checksums: Add function to abstract comparison

This modifies the list_objects and list_objects_at functions
to take an additional argument for the string that a commit starts
with.  If this string arg is not null, it will only list commit
objects beginning with that string.  This allows for a new function
ostree_repo_list_commit_objects_starting_with to pass a partial string
and return a list of all matching commits.  This improves on the
previous strategy of listing refs because it will list all commit objects,
even ones in past history.  This update also includes bugfixes on
error handling and string comparison, and changes the output structure
of resolve_partial_checksum. The new strcuture will no longer return FALSE
without error.  Also, the hashtable foreach now uses iter.  Also
includes modified test file

This large patch moves the core xattr logic down into libgsystem,

allows us to just use that API instead of rolling our own recursive
copy here.

As noted in the new comment though, one case that we are explicitly
regressing is where the new /etc removes a parent directory that's
needed by a modified file.  This seems unlikely for most vendors now,

Colin Walters c65923e642 Add OstreeAsyncProgress, use it for ostree_repo_pull
Several APIs in libostree were moved there from the commandline code,
and have hardcoded g_print() for progress and notifications.  This
isn't useful for people who want to write PackageKit backends, custom
GUIs and the like.

From what I can tell, there isn't really a winning precedent in GLib
for progress notifications.

PackageKit has the model where the source has GObject properties that
change as async ops execute, which isn't bad...but I'd like something
a bit more general where say you can have multiple outstanding async
ops and sensibly track their state.

So, OstreeAsyncProgress is basically a threadsafe property bag with a
change notification signal.

Use this new API to move the GSConsole usage (i.e. g_print()) out from
libostree/ and into ostree/.
