2020-08-07Remove old benchmark tools.Zach Koopmans
Remove the old benchmark-tools directory, including imports in the WORKSPACE file and associated bazel rules. The new Golang benchmark-tools can be found at //test/benchmarks and it is functionally equivalent, excepting syscall_test which can be found in //test/perf/linux. PiperOrigin-RevId: 325529075

This required minor fixes to the bazel wrapper. The "dut_platform" is also changed to "native" to line-up with the system call tests and remove the hard-coded "linux" and "netstack" strings.

2020-07-27Fix for gvisor-builder image.Bhasker Hariharan
As it happens gvisor/tools/bazel.mk:88 useradd --uid $(UID) --non-unique --no-create-home \ adds the user-id to /var/log/lastlog which happens to be a sparse file except Go's tar support can't handle sparse files so it actually tries to allocate the file to seek to the end causing the VM to run out of disk space. See: https://github.com/moby/moby/issues/5419#issuecomment-193876183 The fix is to pass -l to useradd to prevent it from trying to add to lastlog. Fixes #3397 PiperOrigin-RevId: 323492591

2020-07-27Clean-up bazel wrapper.Adin Scannell
The bazel server was being started as the wrong user, leading to issues where the container would suddenly exit during a build. We can also simplify the waiting logic by starting the container in two separate steps: those that must complete first, then the asynchronous bit. PiperOrigin-RevId: 323391161
2020-07-25optimize size and time using "--no-cache-dir"Pratik raj
Using "--no-cache-dir" flag in pip install ,make sure dowloaded packages by pip don't cached on system . This is a best practise which make sure to fetch ftom repo instead of using local cached one . Further , in case of Docker Containers , by restricing caching , we can reduce image size. In term of stats , it depends upon the number of python packages multiplied by their respective size . e.g for heavy packages with a lot of dependencies it reduce a lot by don't caching pip packages. Further , more detail information can be found at https://medium.com/sciforce/strategies-of-docker-images-optimization-2ca9cc5719b6

2020-07-23Convert go_generics tests to starlark.Adin Scannell
For some reason these tests were broken when run via the bazel docker container. The mechanism used was a bit crazy (self-extracting bundle), so convert them to use straight-forward starlark rules. This has the added advantaged that they are now independent tests.

2020-07-23Fix kokoro presubmits!Ayush Ranjan
Fixed the following error: tools/bazel.mk:119: *** Destination not provided.. Stop. The issue was that we were running all make commands in a subshell so variables like $T were not passed on. The other issue was related to credentials. The test passed locally but not on kokoro, the only difference in the workflow was the credentials bit. Also fixed up some other tiny issues I came across, were not blockers. PiperOrigin-RevId: 322782457

2020-07-15Fix errors not getting caught when building vm image.Ting-Yu Wang

2020-07-09Update shim to build using bazel.Adin Scannell
The go.mod dependency tree for the shim was somehow contradictory. After resolving these issues (e.g. explicitly imported k8s 1.14, pulling a specific dbus version), and adding all dependencies, the shim can now be build as part of the regular bazel tree. As part of this process, minor cleanup was done in all the source files: headers were standardized (and include "The gVisor Authors" in addition to the "The containerd Authors" if originally derived from containerd sources), and comments were cleaned up to meet coding standards. This change makes the containerd installation dynamic, so that multiple versions can be tested, and drops the static installer for the VM image itself. This change also updates test/root/crictl_test.go and related utilities, so that the containerd tests can be run on any version (and in cases where it applies, they can be run on both v1 and v2 as parameterized tests).
2020-07-09Allow arbitrary Go commands for go_mod.sh.Adin Scannell
2020-06-26Enable docker IPv6 in kokoroKevin Krakauer
We need docker IPv6 for ip6tables tests. Docker has spotty IPv6 support, so just enabling IPv6 in daemon.json breaks the Ruby image test (AFAICT it breaks anything that tries to use IPv6 to reach the internet). An ip6tables NAT rule is added to handle this. We could make these changes as part of scripts/, but these would overwrite global values and possibly break users' systems. PiperOrigin-RevId: 318508209
2020-06-23Support for saving pointers to fields in the state package.Adin Scannell
Previously, it was not possible to encode/decode an object graph which contained a pointer to a field within another type. This was because the encoder was previously unable to disambiguate a pointer to an object and a pointer within the object. This CL remedies this by constructing an address map tracking the full memory range object occupy. The encoded Refvalue message has been extended to allow references to children objects within another object. Because the encoding process may learn about object structure over time, we cannot encode any objects under the entire graph has been generated. This CL also updates the state package to use standard interfaces intead of reflection-based dispatch in order to improve performance overall. This includes a custom wire protocol to significantly reduce the number of allocations and take advantage of structure packing. As part of these changes, there are a small number of minor changes in other places of the code base: * The lists used during encoding are changed to use intrusive lists with the objectEncodeState directly, which required that the ilist Len() method is updated to work properly with the ElementMapper mechanism. * A bug is fixed in the list code wherein Remove() called on an element that is already removed can corrupt the list (removing the element if there's only a single element). Now the behavior is correct. * Standard error wrapping is introduced. * Compressio was updated to implement the new wire.Reader and wire.Writer inteface methods directly. The lack of a ReadByte and WriteByte caused issues not due to interface dispatch, but because underlying slices for a Read or Write call through an interface would always escape to the heap! * Statify has been updated to support the new APIs. See README.md for a description of how the new mechanism works. PiperOrigin-RevId: 318010298

2020-05-29Fix the APT repository structure.Adin Scannell
This change fixes the apt repository structure to avoid emiting warnings on Ubuntu 18.04 (and potentially other versions). This requires a slight refactor of the repository generation scripts, since we can no longer copy the same release files for different "suites". This should avoid the warning by setting the suite to the distribution: https://github.com/Debian/apt/blob/master/apt-pkg/metaindex.cc#L75 This change also moves over to the standardized Makefile entrypoint, which makes settings clearer and enables local testing.

2020-05-25Ensure docker group exists in the container.Adin Scannell
The --groups command will fail if the group is not defined in /etc/groups, even though it is specified by GID. By coincidence, the group happens to be there for many installations of Ubuntu 18.04 (which uses 999 for the Docker group), but it is strangely absent in others (which use 130). Fixes #2765

2020-05-20Implement gap tracking in the segment set.Reapor-Yurnero
This change was derived from a change by: Reapor-Yurnero <reapor.yurnero@gmail.com> And has been modified by: Adin Scannell <ascannell@google.com> (The original change author is preserved for the commit.) This change implements gap tracking in the segment set by adding additional information in each node, and using that information to speed up gap finding from a linear scan to a O(log(n)) walk of the tree. This gap tracking is optional, and will default to off except for segment instances that set gapTracking equal to 1 in their const lists. PiperOrigin-RevId: 312621607
