This is the first step in actually overhauling the ghw library's context package and moving to a more standard `context.Context` usage. In order to standardize the context usage, we needed to change the way that the ghw-snapshot functionality worked to manually construct a `pkg/context.Context` and call `pkg/context.Context:Do()` while reading the snapshot tarball. In order to do that, I created a new `ghw-snapshot read` command that accepts a single argument to the snapshot tarball path to read: ``` ➜ ghw git:(overhaul-snapshot) ✗ GHW_DISABLE_WARNINGS=1 go run cmd/ghw-snapshot/main.go read testdata/snapshots/linux-amd64-intel-xeon-L5640.tar.gz block storage (8 disks, 723GB physical storage) cpu (2 physical packages, 12 cores, 24 hardware threads) gpu (0 graphics cards) memory (66GB physical, 63GB usable) net (0 NICs) topology NUMA (2 nodes) chassis type=unknown vendor=unknown version=unknown bios vendor=unknown version=unknown baseboard vendor=unknown version=unknown product=unknown product family=unknown name=unknown vendor=unknown sku=unknown version=unknown PCI (82 devices) ➜ ghw git:(overhaul-snapshot) ✗ GHW_DISABLE_WARNINGS=1 go run cmd/ghw-snapshot/main.go read testdata/snapshots/linux-amd64-amd-ryzen-1600.tar.gz block storage (8 disks, 3TB physical storage) cpu (1 physical package, 6 cores, 12 hardware threads) gpu (1 graphics card) memory (32GB physical, 32GB usable) net (4 NICs) topology NUMA (0 nodes) chassis type=unknown vendor=unknown version=unknown bios vendor=unknown version=unknown baseboard vendor=unknown version=unknown product=unknown product family=unknown name=unknown vendor=unknown sku=unknown version=unknown PCI (43 devices) ``` A followup series of patches will make the aforementioned changes to `pkg/context` and remove the `pkg/context.Context:Do()` method and put that entirely in the `cmd/ghw-snapshot/command/read.go` file which is the only place we actually use it.
