- 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`.

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.
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

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).

We currently have an internal-only library, but the sources for it are
in the same dir as the app. For future work on a public shared
library, we'll need a clearer source structure.
Start by just renaming the app files into `src/app/`, and the internal
private library into `src/libpriv/`, with the appropriate
`Makefile.am` changes.
