Fixup search
podman-remote search had some FIXMEs in tests that were failing.
So I reworked the search handler to use the local abi.  This
means the podman search and podman-remote search will use the
same functions.

While doing this, I noticed we were just outputing errors via
logrus.Error rather then returning them, which works ok for
podman but the messages get lost on podman-remote.  Changed
the code to actually return the error messages to the caller.

This allows us to turn on the remaining podman-remote FIXME
tests.

Exorcise Driver code from libpod/define
2021-01-12 14:02:32 -05:00
Matthew Heon befd40b57d Exorcise Driver code from libpod/define
The libpod/define code should not import any large dependencies,
as it is intended to be structures and definitions only. It
included the libpod/driver package for information on the storage
driver, though, which brought in all of c/storage. Split the
driver package so that define has the struct, and thus does not
need to import Driver. And simplify the driver code while we're
at it.

Paul Holzinger 8452b768ec Fix problems reported by staticcheck
`staticcheck` is a golang code analysis tool. https://staticcheck.io/

This commit fixes a lot of problems found in our code. Common problems are:
- unnecessary use of fmt.Sprintf
- duplicated imports with different names
- unnecessary check that a key exists before a delete call

There are still a lot of reported problems in the test files but I have
not looked at those.

Baron Lenardson b90f7f9095 Rework pruning to report reclaimed space
This change adds code to report the reclaimed space after a prune.
Reclaimed space from volumes, images, and containers is recorded
during the prune call in a PruneReport struct. These structs are
collected into a slice during a system prune and processed afterwards
to calculate the total reclaimed space.

Closes #8658

With additional stores there is a risk that you could have

read/only store versus a newer version in the read/write store.

This patch will ignore multiple images with the same name iff
one is read/write and all of the others are read/only.

TomSweeneyRedHat 33366a2cda Convert Split() calls with an equal sign to SplitN()
After seeing #7759, I decided to look at the calls in
Podman and Buildah to see if we had issues with strings.Split()
calls where an "=" (equals) sign was in play and we expected
to split on only the first one.

There were only one or two that I found in here that I think
might have been troubling, the remainder are just adding
some extra safety.

I also had another half dozen or so that were checking length
expectations appropriately, those I left alone.

Properly handle podman run --pull command
Currently the --pull missing|always|never is ignored

This PR implements this for local API.  For remote we
need to default to pullpolicy specified in the containers.conf
file.

Also fixed an issue when images were matching other images names
based on prefix, causing images to always be pulled.

I had named an image myfedora and when ever I pulled fedora, the system
thought that it there were two images named fedora since it was checking
for the name fedora as well as the prefix fedora.  I changed it to check
for fedora and the prefix /fedora, to prefent failures like I had.

Valentin Rothberg ecae5f7ade image list: return all associated names
Always return all associated names / repo tags of an image and fix a bug
with malformed repo tags.

Previously, Podman returned all names only with `--all` but this flag
only instructs to list intermediate images and should not alter
associated names.  With `--all` Podman queried the repo tags of an image
which splits all *tagged* names into repository and tag which is then
reassembled to eventually be parsed again in the frontend.  Lot's of
redundant CPU heat and buggy as the reassembly didn't consider digests
which ultimately broke parsing in the frontend.

images: speed up lists
2020-08-08 07:14:37 -04:00
Valentin Rothberg 8827100b98 image list: speed up
Listing images has shown increasing performance penalties with an
increasing number of images.  Unless `--all` is specified, Podman
will filter intermediate images.  Determining intermediate images
has been done by finding (and comparing!) parent images which is
expensive.  We had to query the storage many times which turned it
into a bottleneck.

Instead, create a layer tree and assign one or more images to nodes that
match the images' top layer.  Determining the children of an image is
now exponentially faster as we already know the child images from the
layer graph and the images using the same top layer, which may also be
considered child images based on their history.

On my system with 510 images, a rootful image list drops from 6 secs
down to 0.3 secs.

Also use the tree to compute parent nodes, and to filter intermediate
images for pruning.

Valentin Rothberg b05888a97d search: allow wildcards
Allow wildcards in the search term.  Note that not all registries

Note that searching implies figuring out if the specified search term
includes a registry.  If there's not registry detected, the search term
will be used against all configured "unqualified-serach-registries" in
the registries.conf.  The parsing logic considers a registry to be the
substring before the first slash `/`.

With these changes we now not only support wildcards but arbitrary
input; ultimately it's up to the registries to decide whether they
support given input or not.
