| * Let containers/storage keep track of mountsDaniel J Walsh2018-07-19
| | | | | | | | | | | | | | | | | | | | | | Currently we unmount storage that is still in use. We should not be unmounting storeage that we mounted via a different command or by podman mount. This change relies on containers/storage to umount keep track of how many times the storage was mounted before really unmounting it from the system. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>

* | podman-top: use containers/psgoValentin Rothberg2018-07-19
|/ | | | | | | | | | | | | | | | | Use github.com/containers/psgo instead of execing `ps (1)`. The psgo library enables a much more flexible interface with respect to which data to be printed (e.g., capabilities, seccomp mode, PID, PCPU, etc.) while the output can be parsed reliably. The library does not use ps (1) but parses /proc and /dev instead. To list the processes of a given container, psgo will join the mount namespace of the given container and extract all data from there. Notice that this commit breaks compatibility with docker-top.

| | | | | | | | | | | | There's no reason --size cannot be used together with a Go template - in fact, using a Go template for {{.Size}} without --size being passed will not work. Allow use of --namespace and --size with Go templates, but not with --quiet. Do not allow --namespace and --size at the same time. Signed-off-by: Matthew Heon <mheon@redhat.com>

* Don't print rootfs and rw sizes if they're emptyMatthew Heon2018-07-13
| | | | | | | | | | | | We're printing them unconditionally now, even if --size is not passed, which is confusing (you see a pair of 0s for container size, when it is clearly not 0). This may introduce bugs related to containers with an rwsize of 0 (freshly created from an image) and --size specified, but is definitely better than what we have now.

| | | | | | | | | | | | | A number of fields were never being populated. Populate them as best we can.

This commit adjusts that approach to use a single select to cover "have we been canceled?", "has there been a resize signal?", and (when we have one) "can we write the most recent resize event to the resize channel?". A side benefit to this approach is that if we have a slow resize consumer and several resize signals, the resizeTty function will keep updating its local resizeEvent. Once the resize channel is able to accept, only the most-recent event will be written. Previously we'd have written one resize event for every received signal, even if the resize consumer was falling behind.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | some platforms and operating systems do not have varlink. in those cases, we need to be able to turn off enablement of varlink in podman. this can now be done with BUILDTAGS passed to the build though perhaps in the future will be better. the default is to build with varlink Signed-off-by: baude <bbaude@redhat.com> squash! make varlink optional for podman The API.md and cmd/podman/varlink/ioprojectatomicpodman.go targets will continue to work regardless of the presence (or not) of 'varlink' is in BUILDTAGS. However, cmd/podman/varlink/ioprojectatomicpodman.go is now only required by the podman target when BUILDTAGS contains 'varlink'. API.md had also been an podman dependency since 5b2627dd (Makefile: Drop find-godeps.sh for podman target, 2018-05-15, #776) when I expanded varlink_api_generate. It had been an indirect podman dependency (via varlink_api_generate) since 25263558 (Generate varlink API documentation automatically, 2018-05-07, #734). But the podman executable obviously doesn't depend on the Markdown file, so I'm removing that dependency here. Signed-off-by: baude <bbaude@redhat.com> squash! make varlink optional for podman The command-pointer approach will scale well if/when we add additional optional commands behind their own build tags, because those tags won't all be competing for the same getOptionalCommands namespace.
