* Use imageParts.referenceWithRegistry in pullGoalFromPossiblyUnqualifiedNameMiloslav Trmač2019-01-14
| | | | | | | | | | | | | | | | | | | CHANGES BEHAVIOR. This bypasses .assemble, and preserves the original lack of tag / original digest instead of adding :latest/:none (still subject to ParseStoreReference normalization). Using the original digest seems clearly correct; dropping the :latest suffix from .image strings, and adding /library to docker.io/shortname, only affects user-visible input; later uses of the return value of pullImageFrom... use ParseStoreReference, which calls reference.ParseNormalizedNamed and reference.TagNameOnly, so the image name should be processed the same way whether it contains a tag, or libray/, or not. This also allows us to drop the problematic hasShaInInputName heuristic/condition/helper. Signed-off-by: Miloslav Trmač <mitr@redhat.com>

* Don't use imageParts.assemble when pulling from a qualified nameMiloslav Trmač2019-01-14
| | | | | | | | | | | | | | | | | | | | | | | CHANGES BEHAVIOR. If the name is qualified, instead of decomposing it into components and re-assembling, just use the input name unmodified: - For name:tag values, .assemble() just recreates the input. - For untagged values, .assemble() adds ":latest"; we keep the input as is, but both docker.ParseReference and storage.Transport.ParseStoreReference use reference.TagNameOnly() already. - For digested references, .assemble() adds ":none", but the code was already bypassing .assemble() on that path already - for the source reference. For the destination, this replaces a :none destination with a the @digest reference, as expected. Note that while decompose() has already parsed the input, it (intentionally) bypassed the docker.io/library normalization; therefore we parse the input again (via docker.ParseReference) to ensure that the reference is normalized.

* We are mistakenly seeing repos as registries.Daniel J Walsh2018-08-31
| | | | | | | | | | | | Currently `podman pull rhel7/rhel-tools` is failing because it sees rhel7 as a registry. This change will verify that the returned registry from the parser is actually a registry and not a repo, if a repo it will return the correct content, and we will pull the image.

* Replace getPullRefName by Runtime.getPullRefPairMiloslav Trmač2018-08-02
| | | | | | | | | | | | | | | | | | This more or less reverts 9c9401a96c0b7d43dcea19c2972ef9612cc0a136 "Replace getPullRefPair with getPullRefName"; now that tests don't require us to use pullRefName, move creation of storage references deeper into the calls stack to reduce string use. ir.getSinglePullRefNameGoal is accordingly updated to ir.getSinglePullRefPairGoal, and we need to add a ~duplicate singlePullRefPairGoal; that duplication of singlePullRefNameGoal will soon be resolved by dropping singlePullRefNameGoal. Should not change behavior. Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1198 Approved by: mheon
* Test Runtime.pullGoalFromPossiblyUnqualifiedName instead of pullGoalNameFrom...Miloslav Trmač2018-08-02
| | | | | | | | | | | | | | Similarly to pullGoalNamesFromImageReference, use a storage.Store and test the actually created references; that is more representative, and clearly shows the impact of further normalization in storageReference (like defaulting to :latest on NameOnly references). Only modifies tests, so does not change behavior. Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1198 Approved by: mheon
* Test Runtime.pullGoalFromImageReference instead of ↵Miloslav Trmač2018-08-02
| | | | | | | | | | | | | | | | | | | | | | | | | pullGoalNamesFromImageReference pullGoalNamesFromImageReference has been added only to allow testing without a storage.Store, because I thought that a storage.Store can only be created by root. It turns out that non-root stores, at least good enough for reference parsing and formatting, are possible (and have existed in c/image/storage tests), so this creates such a store, and modifies the existing test to test the created c/image/storage.storageReference values instead of strings; that is more representative, and clearly shows the impact of further normalization in storageReference (like defaulting to :latest on NameOnly references). Eventually we will want to get rid of pullGoalNames / pullRefName. Only modifies tests, so does not change behavior. Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1198 Approved by: mheon
* Do not re-parse the list of search registries just for an error messageMiloslav Trmač2018-08-01
| | | | | | | | | | | | | | | | ... when we even only count them. This eliminates a rare error case, and saves time re-reading and re-parsing the input. (We still compute registryPath redundantly, and it may get out of sync.) Should not change behavior (but does not add unit tests).

* Eliminate duplicate determination whether to use search registriesMiloslav Trmač2018-08-01
| | | | | | | | | | | | Instead of duplicating the hasRegistry logic, just record whether we did use search or not. Should not change behavior (but does not add unit tests for all of it). Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1176 Approved by: rhatdan
* Eliminate the "DockerArchive means pull all refPairs" special caseMiloslav Trmač2018-08-01
| | | | | | | | | | | | Instead, encode it explicitly in pullGoal.pullAllPairs. Should not change behavior (but does not add unit tests for all of it). Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1176 Approved by: rhatdan
* Introduce struct pullGoalNamesMiloslav Trmač2018-08-01
| | | | | | | | | | | | | | | | | | | This is an intermediate version of pullGoal, which exists basically only for easier testing without containers-storage: (i.e. root access) in unit tests. Like pullGoal, we will add more members to make it useful in the future. RFC: Unlike pullGoal, the return value is *pullGoalNames, because there are quite a few (return nil, err) cases which would be more difficult to read when returning a value. Should not change behavior. Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1176 Approved by: rhatdan
* Use []pullRefName instead of []*pullRefNameMiloslav Trmač2018-08-01
| | | | | | | | | | | | | | | We are passing the values, don't really need the pointer sharing semantics, and the structures are small enough, and the arrays short enough, that we very likely lose on the indirect accesses more than we save on quicker copying of the slices when extending them. Value semantics is safer anyway. Should not change behavior. Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1176 Approved by: rhatdan
* Remove the error return value from getPullRefNameMiloslav Trmač2018-08-01
| | | | | | | | | | | ... it is always nil. Should not change behavior. Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1176 Approved by: rhatdan
* Split refNamesFromImageReference from Runtime.getPullListFromRefMiloslav Trmač2018-08-01
| | | | | | | | | | | | | | Again, that makes the core logic independent from Runtime == containers-storage, and easier to test independently. So, this also adds tests. Should not change behavior. Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1176 Approved by: rhatdan
* Replace getPullRefPair with getPullRefNameMiloslav Trmač2018-08-01
| | | | | | | | | | | | | | | | | | | ... and use pullRefPairsFromRefNames to convert to the desired data structure later. This will make both getPullRefName, and later the bulk of getPullListFromRef, independent of the storage, and thus much easier to test. Then add tests for getPullRefName. (Ideally they should be shorter, e.g. hopefully the .image member can be eliminated.) Should not change behavior, except that error messages on invalid dstName will now include the value.

* Make refNamesFromPossiblyUnqualifiedName independent from ImageMiloslav Trmač2018-07-23
... which finally makes it very easy to add comprehensive tests; so do that. Should not change behavior. Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1112 Approved by: rhatdan
