This API was added to libhif a while ago. I'm adding this now because
libhif was changed recently to write the dnf copy of the yumdb, and we
didn't have code to remove it explicitly.
It's better not to write it in the first place.
We noticed that tree composes failed with a missing `atomic` package,
when really what happend is Fedora 22 was released and the repo
metadata moved from `development/` to `released/`.
See https://github.com/hughsie/libhif/pull/47
- Can also give you a file descriptor
- Takes a constant string as input, returning a mutated string as a
separate variable which means that one can check whether the variable
is `NULL` to know whether or not one needs to `rm -rf` it on error
paths.
The refsack code was using the latter, and it stood out. Now that
we're making use of explicit export markers, there's no need to uglify
internal APIs with a leading `_`.
While `rpm-util.c` may not best describe this, it's where most
of this code is ending up. Let's further centralize things.
We more consistently return an `RpmOstreeRefSack` instead of a
`HySack`, where the former supports refcounting and knows how to clean
up its temporary directory if it was allocated from a commit.
And now, finally the actual goal is achieved. \o/
Only one code path dealing with extracting the rpm database from an
OSTree commit.
An astute reader would notice that the `root` member of the struct was
actually only necessary as of a few commits ago. But said astute
reader would also realize it's kind of late in the evening and not
worth rebasing it to where it would properly go.
hawkey and libsolv are both patched to look in `usr/share/rpm` if the
db can't be found in `/var/lib/rpm`. However, librpm itself isn't.
One *can* override it with a macro...which is process global. Yuck.
Needs fixing.
Anyways, we can just make a symlink. That's a lot easier than writing
a patch for librpm and waiting a billion years to be able to use it
everywhere we care about.
This will help unify the librpm tempdir code with the hawkey tempdir
code.
As far as I can tell, this is basically a way to specify the temporary
directory. That significantly complicates the code as it now
needs to keep track of whether or not it owns the temporary directory.
This hinders unifying this code with the hawkey query path.
Because of this, and since I'm not aware of a use case for specifying
this tempdir, let's remove it.
It was only used to access the yumdb, which we don't use because:
- It badly exacerbates the OSTree one-HTTP-request-per-object issue
- We're assembling multiple repos on the server side, so things like
who took the action aren't relevant.
But the reason I did this patch at the moment is because I want to
unify the code that's creating tempdirs from commits so we can feed
real files to librpm.
For a future patch, I want to add an API to get an rpmts for a commit,
instead of a hawkey Sack, because libsolv doesn't expose some
optimized queries that we can get by just going directly to librpm,
such as package file owners.
We had `src/lib` having its own little private library; I wanted to
use some of it inside `src/libpriv`, so let's consistently have all
private utility code in `src/libpriv`.

Equivalent to hy_package_cmp(), but works for comparing packages from
different memory pools.
This a stop gap measure in light of
https://github.com/rpm-software-management/hawkey/pull/90
If and when that pull request gets merged, then this function could at
some later point simply call hy_package_cmp().
This is a step forward to deduplicating; the client tooling now calls
into the public API for diffs, rather than using the older internal
function.
Note: this patch also links the client against the public library.
This is a *third* implementation of rpm database diffs in the code,
but it is now a public introspectable shared library API.
Further commits will change the command line tools to use this, and
then after that we'll further deduplicate the `db diff` from this
code.
On the plus side, we share some code between the library and the
binary now. On the downside, because `librpmostreepriv.la` is a
noinst library, its code text is duplicated between the shared library
and binary, at least until we either:
- Have the binary solely use the public shared library (like ostree does)
- Install `librpmostreepriv.so` to e.g. `/usr/lib64/rpm-ostree/librpmostreepriv.so`
without the headers being public
We presently have 3 internal code paths that are doing rpmdb
inspection. This conversion to fd-relative for one of them is a
generic cleanup preparatory to de-duplicating.
Note this bumps libglnx to include
381ca54ee3
The file is automatically populated by systemd when it is empty.
Apparently it doesn't work when the file is missing (as of
systemd-219-9.fc22).

In pretty mode (--pretty), print signatures for each listed deployment.
Otherwise, just print signatures for the booted deployment at the end to
preserve the tabular formatting of the deployment list.
The `QueryResult` class ended up being too awkward; having NEVRA
strings meant for example that clients would have to parse them. It
would be harder to present something like the current `rpm-ostree
upgrade` package diff output.
Now...I debated quite a while before doing this patch. The thing
that's really awful about creating this library is there are *SO MANY*
layers. rpm-ostree → libhif → hawkey → libsolv → librpm. It's enough
to make one question whether one is actually accomplishing anything or
just contributing to a collective insanity...
Let's pretend for now it's the former.
