* pkg/ctime: Factor libpod/finished* into a separate packageW. Trevor King2018-07-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This removes some boilerplate from the libpod package, so we can focus on container stuff there. And it gives us a tidy sub-package for focusing on ctime extraction, so we can focus on unit testing and portability of the extraction utility there. For the unsupported implementation, I'm falling back to Go's ModTime [1]. That's obviously not the creation time, but it's likely to be closer than the uninitialized Time structure from cc6f0e85 (more changes to compile darwin, 2018-07-04, #1047). Especially for our use case in libpod/oci, where we're looking at write-once exit files. The test is more complicated than I initially expected, because on Linux filesystem timestamps come from a truncated clock without interpolation [2] (and network filesystems can be completely decoupled [3]). So even for local disks, creation times can be up to a jiffie earlier than 'before'. This test ensures at least monotonicity by creating two files and ensuring the reported creation time for the second is greater than or equal to the reported creation time for the first. It also checks that both creation times are within the window from one second earlier than 'before' through 'after'. That should be enough of a window for local disks, even if the kernel for those systems has an abnormally large jiffie. It might be ok on network filesystems, although it will not be very resilient to network clock lagging behind the local system clock.

* spec: Make addPrivilegedDevices and createBlockIO per-platformW. Trevor King2018-07-06
| | | | | | | | | | | | | | | | | | | | | | | | | b96be3af (changes to allow for darwin compilation, 2018-06-20, #1015) made AddPrivilegedDevices per-platform and cc6f0e85 (more changes to compile darwin, 2018-07-04, #1047) made CreateBlockIO per-platform. But both left but left out docs for the unsupported version [1]: pkg/spec/config_unsupported.go:18:1:warning: exported method CreateConfig.AddPrivilegedDevices should have comment or be unexported (golint) pkg/spec/config_unsupported.go:22:1:warning: exported method CreateConfig.CreateBlockIO should have comment or be unexported (golint) To keep the docs DRY, I've restored the public methods and their docs, and I've added new, internal methods for the per-platform implementations.

* rootless: Merge rootless.go back into rootless_linux.goW. Trevor King2018-07-06
| | | | | | | | | | | | | | | The files were split apart by b96be3af (changes to allow for darwin compilation, 2018-06-20, #1015), but the C import and two functions left in rootless.go are all Linux-specific as well. This commit moves all of the pre-b96be3af rootless.go into rootless_linux.go, just adding the '// +build linux' header (b96be3af also scrambled the + in that header) and keeping the new GetRootlessUID from a1545fe6 (rootless: add function to retrieve the original UID, 2018-07-05, #1048).

* more changes to compile darwinbaude2018-07-05
| | | | | | | | | | | | | | | | this should represent the last major changes to get darwin to **compile**. again, the purpose here is to get darwin to compile so that we can eventually implement a ci task that would protect against regressions for darwin compilation. i have left the manual darwin compilation largely static still and in fact now only interject (manually) two build tags to assist with the build. trevor king has great ideas on how to make this better and i will defer final implementation of those to him.

* pkg/hooks/exec: Add a new package for local hook executionW. Trevor King2018-05-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This wraps os/exec to: * Clear the environment when the hook doesn't set 'env'. The runtime spec has [1]: > * env (array of strings, OPTIONAL) with the same semantics as IEEE > Std 1003.1-2008's environ. And running execle or similar with NULL env results in an empty environment: $ cat test.c #include <unistd.h> int main() { return execle("/usr/bin/env", "env", NULL, NULL); } $ cc -o test test.c $ ./test ...no output... Go's Cmd.Env, on the other hand, has [2]: > If Env is nil, the new process uses the current process's environment. This commit works around that by setting []string{} in those cases to avoid leaking the runtime environment into the hooks. * Roll the 'timeout' value (if set) into the passed context. There's no need for two separate ways to cancel hook execution. * Add a configurable timeout on abandoning a post-kill wait. The waiting goroutine will continue and eventually reap the process, but this avoids blocking the Run() call when that takes inordinately long (for example, if a GPU cleanup hook is stuck in I/O sleep [3]). The 'env' output format is specified in POSIX [4].

| | | | | | | | | | | | | | | | | | | | | | | The process property is optional [1], which this package already handled appropriately, although I've added a new test here to guard against regressions. The process.args entry is required when process is set [2], and it's also required to contain at least one entry [3].
