* Add support for containers.conf volume timeoutsMatthew Heon2022-08-23
| | | | | | | | | | | | | | | | | | | | | | | | Also, do a general cleanup of all the timeout code. Changes include: - Convert from int to *uint where possible. Timeouts cannot be negative, hence the uint change; and a timeout of 0 is valid, so we need a new way to detect that the user set a timeout (hence, pointer). - Change name in the database to avoid conflicts between new data type and old one. This will cause timeouts set with 4.2.0 to be lost, but considering nobody is using the feature at present (and the lack of validation means we could have invalid, negative timeouts in the DB) this feels safe. - Ensure volume plugin timeouts can only be used with volumes created using a plugin. Timeouts on the local driver are nonsensical. - Remove the existing test, as it did not use a volume plugin. Write a new test that does. The actual plumbing of the containers.conf timeout in is one line in volume_api.go; the remainder are the above-described cleanups. Signed-off-by: Matthew Heon <mheon@redhat.com>
* libpod: switch to golang native error wrappingSascha Grunert2022-07-05
| | | | | | | | | We now use the golang error wrapping format specifier `%w` instead of the deprecated github.com/pkg/errors package. [NO NEW TESTS NEEDED] Signed-off-by: Sascha Grunert <sgrunert@redhat.com>
* podman volume create --opt=o=timeout...cdoern2022-06-09
| | | | | | | add an option to configure the driver timeout when creating a volume. The default is 5 seconds but this value is too small for some custom drivers. Signed-off-by: cdoern <cdoern@redhat.com>

* Set volume NeedsCopyUp to false iff data was copied upDaniel J Walsh2022-01-06
| | | | | | | | | | | | Currently Docker copies up the first volume on a mountpoint with data. Fixes: https://github.com/containers/podman/issues/12714 Also added NeedsCopyUP, NeedsChown and MountCount to the podman volume inspect code. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
* bump go module to v3Valentin Rothberg2021-02-22
| | | | | | | | | We missed bumping the go module, so let's do it now :) * Automated go code with github.com/sirkon/go-imports-rename * Manually via `vgrep podman/v2` the rest Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* Initial implementation of volume pluginsMatthew Heon2021-01-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This implements support for mounting and unmounting volumes backed by volume plugins. Support for actually retrieving plugins requires a pull request to land in containers.conf and then that to be vendored, and as such is not yet ready. Given this, this code is only compile tested. However, the code for everything past retrieving the plugin has been written - there is support for creating, removing, mounting, and unmounting volumes, which should allow full functionality once the c/common PR is merged. A major change is the signature of the MountPoint function for volumes, which now, by necessity, returns an error. Named volumes managed by a plugin do not have a mountpoint we control; instead, it is managed entirely by the plugin. As such, we need to cache the path in the DB, and calls to retrieve it now need to access the DB (and may fail as such). Notably absent is support for SELinux relabelling and chowning these volumes. Given that we don't manage the mountpoint for these volumes, I am extremely reluctant to try and modify it - we could easily break the plugin trying to chown or relabel it. Also, we had no less than *5* separate implementations of inspecting a volume floating around in pkg/infra/abi and pkg/api/handlers/libpod. And none of them used volume.Inspect(), the only correct way of inspecting volumes. Remove them all and consolidate to using the correct way. Compat API is likely still doing things the wrong way, but that is an issue for another day. Fixes #4304 Signed-off-by: Matthew Heon <matthew.heon@pm.me>

* move go module to v2Valentin Rothberg2020-07-06
| | | | | | | | | | | | | | | With the advent of Podman 2.0.0 we crossed the magical barrier of go modules. While we were able to continue importing all packages inside of the project, the project could not be vendored anymore from the outside. Move the go module to new major version and change all imports to `github.com/containers/libpod/v2`. The renaming of the imports was done via `gomove` [1].

* container: move volume chown after spec generationGiuseppe Scrivano2020-06-29

* Deprecate & remove IsCtrSpecific in favor of IsAnonMatthew Heon2020-01-29
| | | | | | | | | | | | | | | | | | | In Podman 1.6.3, we added support for anonymous volumes - fixing our old, broken support for named volumes that were created with containers. Unfortunately, this reused the database field we used for the old implementation, and toggled volume removal on for `podman run --rm` - so now, we were removing *named* volumes created with older versions of Podman. We can't modify these old volumes in the DB, so the next-safest thing to do is swap to a new field to indicate volumes should be removed. Problem: Volumes created with 1.6.3 and up until this lands, even anonymous volumes, will not be removed. However, this is safer than removing too many volumes, as we were doing before.

* Implement backend for 'volume inspect'Matthew Heon2019-08-02
Begin to separate the internal structures and frontend for inspect on volumes. We can't rely on keeping internal data structures for external presentation - separating presentation and internal data format is good practice. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
