* podman version: use report.Formatter over TemplatePaul Holzinger2022-09-13
| | | | | | | | | | | | | | | Currently the podman command --format output code uses a mix of report.Formatter and report.Template. I patched report.Formatter to correctly handle newlines[1]. Since we cannot fix this with report.Template we have to migrate all users to report.Formatter. This ensures consistent behavior for all commands. This change does not change the output.

* podman ssh work, using new c/common interfaceCharlie Doern2022-08-09
| | | | | | | | | | | | | | | | | | | implement new ssh interface into podman this completely redesigns the entire functionality of podman image scp, podman system connection add, and podman --remote. All references to golang.org/x/crypto/ssh have been moved to common as have native ssh/scp execs and the new usage of the sftp package. this PR adds a global flag, --ssh to podman which has two valid inputs `golang` and `native` where golang is the default. Users should not notice any difference in their everyday workflows if they continue using the golang option. UNLESS they have been using an improperly verified ssh key, this will now fail. This is because podman was incorrectly using the ssh callback method to IGNORE the ssh known hosts file which is very insecure and golang tells you not yo use this in production. The native paths allows for immense flexibility, with a new containers.conf field `SSH_CONFIG` that specifies a specific ssh config file to be used in all operations. Else the users ~/.ssh/config file will be used. podman --remote currently only uses the golang path, given its deep interconnection with dialing multiple clients and urls. My goal after this PR is to go back and abstract the idea of podman --remote from golang's dialed clients, as it should not be so intrinsically connected. Overall, this is a v1 of a long process of offering native ssh, and one that covers some good ground with podman system connection add and podman image scp.

* / podman image scp remote support & podman image scp taggingcdoern2022-06-28
|/ | | | | | | | | | | | | | | | | | | add support for podman-remote image scp as well as direct access via the API. This entailed a full rework of the layering of image scp functions as well as the usual API plugging and type creation also, implemented podman image scp tagging. which makes the syntax much more readable and allows users t tag the new image they are loading to the local/remote machine: allow users to pass a "new name" for the image they are transferring `podman tag` as implemented creates a new image im `image list` when tagging, so this does the same meaning that when transferring images with tags, podman on the remote machine/user will load two images ex: `podman image scp computer1::alpine computer2::foobar` creates alpine:latest and localhost/foobar on the remote host implementing tags means removal of the flexible syntax. In the currently released podman image scp, the user can either specify `podman image scp source::img dest::` or `podman image scp dest:: source::img`. However, with tags this task becomes really hard to check which is the image (src) and which is the new tag (dst). Removal of that streamlines the arg parsing process Signed-off-by: Charlie Doern <cdoern@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Firstly, reset is now managed by the runtime itself as a part of initialization. This ensures that it can be used even with runtimes that would otherwise fail to be created - most notably, when the user has changed a core path (runroot/root/tmpdir/staticdir). Secondly, we now attempt a best-effort removal even if the store completely fails to be configured. Third, we now hold the alive lock for the entire reset operation. This ensures that no other Podman process can start while we are running a system reset, and removes any possibility of a race where a user tries to create containers or pull images while we are trying to perform a reset. [NO NEW TESTS NEEDED] we do not test reset last I checked. Fixes #9075 Signed-off-by: Matthew Heon <mheon@redhat.com>

* shell completion --format: use structs by referencePaul Holzinger2022-04-28
| | | | | | | | | | | | For the AutocompleteFormat function we expect the correct template struct which is used in the golang template. The function can handle both struct and pointer to a struct. Using the reference is more efficient since it doe snot have to copy the whole struct. Also change some structs to use he actual type from the template instead of some nested one to make sure it has to correct fields. Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* shell completion --format: work with nil structsPaul Holzinger2022-04-28
| | | | | | | | | | | | | AutocompleteFormat() takes the format struct as argument. Often the structs are deeply nested and contain other structs. Up until now if there was a pointer to a struct the logic was not able to get the field names from that, simply because the pointer was nil. However it is possible to create a new initialized type with reflect.New(). This allows us to complete all struct fields/functions even when there nil pointers. Therefore we can drop the extra initialization which was done by some callers. Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* enable gocritic linterPaul Holzinger2022-04-26
| | | | | | | | | | | | | | | | | | | | | | The linter ensures a common code style. - use switch/case instead of else if - use if instead of switch/case for single case statement - add space between comment and text - detect the use of defer with os.Exit() - use short form var += "..." instead of var = var + "..." - detect problems with append() ``` newSlice := append(orgSlice, val) ``` This could lead to nasty bugs because the orgSlice will be changed in place if it has enough capacity too hold the new elements. Thus we newSlice might not be a copy. Of course most of the changes are just cosmetic and do not cause any logic errors but I think it is a good idea to enforce a common style. This should help maintainability. Signed-off-by: Paul Holzinger <pholzing@redhat.com>

* podman system df: fix percent calculationPaul Holzinger2022-03-21
| | | | | | | | | | | | | | | | The calculate the percentage we need floating point numbers. The current code however casted the result of reclaimable/size to an int first. Casting to an int in go will just discard the decimal points, thus the result was either 0 or 1 so if multiplied by 100 it would show up as 0% or 100%. To fix this we have to multiply by 100 first before casting the result to an int. Also add a check for div by zero which results in NaN and use math.Round() to correctly round a number.

* system prune: remove all networksPaul Holzinger2022-02-03
| | | | | | | | | | | | | | | podman system prune should also remove all networks. When we want to users to migrate to the new network stack we recommend to run podman system reset. However this did not remove networks and if there were still networks around we would continue to use cni since this was considered an old system. There is one exception for the default network. It should not be removed since this could cause other issues when it no longer exists. The network backend detection logic ignores the default network so this is fine.
