In the short term getting this test enabled will help the installer progress. * Run format * Use strict version for zipkin (#15187) Signed-off-by: clyang82 <clyang@cn.ibm.com> * change to apps/v1 (#15210) * change to apps/v1 for samples (#15212) * change to appsv1 (#15213) * Creating helm charts for local release.

In the current chart defaults, Citadel is not granted *any* namespace related permissions, despite making a namespace read in the istioEnabledObject function. * Fix for Makefile breakage in #15140 (#15196) Fixes #15192 * [Testing] New utility for downloading Envoy binary (#14922) This is split out from #14614 and is needed for dynamically building docker images for the Echo component. Overview: - Added parsing for istio.deps - Moved test utilities for downloading and extracting tar.gz files to pkg/test/util - Added utility for downloading the current release of the envoy linux binary. * add yamllint (#14904) * add yamllint check into prow * fix encoding issue for grafana/values.yaml * fix encoding issue for values.yaml * Fix metric description typos (#15111) Found those while looking at metrics endpoint. * Replace zipkin test using new integration test framework (#14769) * Replace zipkin test using new integration test framework Fix golang errors Add license headers Fixed based on feedback Change calls to product page to 1 from 10 for client tracing Add ability to query for client trace id Fix golang error * Fix golang error * update kind installation step.

The native environment now creates its own Docker network, to which all Echo instance containers are attached. Since they're all on the same Docker network, they have built-in reachability. The Echo+sidecar Dockerfile is a blend of the existing Dockerfile and the setup used for raw VMs. Going forward, I expect we'll build on this and create a common Dockerfile to support non-k8s use cases. Limitations: - This PR does not yet enable mTLS. The connection to Pilot has been switched to TLS, however the mesh config is not truly configurable yet in the native environment. We need to re-think how helm settings might be set for the native environment. - The Docker images are currently built every time the tests are run. While this guarantees that we're running with the latest, it adds a bit of time to the duration of the test run (e.g. the sidecar image takes ~30s to build). Need to investigate ways of detecting when the image needs to be built to avoid this overhead, as well as the additional storage required for several duplicate Docker images. - Currently using a copy of Go code for performing the untar of the downloaded Envoy. Should investigate alternatives or write our own version. - Not currently using the node agent. Once we have a native citadel, we can consider enabling it. Fixes #13177 * Fixes #15250.

(#15227) * Grafana additional env for config changes (#14796) * Added section for configuring additional environment variable configs for grafana to override certain grafana.ini settings like adding SMTP settings. * Removed redundance templating code. Moved grafana env to demo config file. * Removed demo grafana config file. Moved the env and envSecrets values to grafana chart values file with comments on how to use. * Fix getServiceLoadBalancer (#15344) A recent change (#14944) modified this logic which was causing it to no longer actually poll for the ingress ip -- it would return "" and use that rather than erroring properly. With this change we will continue to retry if we don't get a valid IP. * format code (#15259) * Fix TestRBACV1Group and TestRBACV2Group (#15314) * fix JWT token * use groups instead of group * one more file * fix format * Accommodate CR feedback. (#15340) * Turn off HPA on demo profile (#15346) Currently each component has 10m cpu requests and an HPA that scales at 80% CPU usage meaning they will immediately scale up. This turns off the HPA for the demo. * Optimize yamllint to run in one process (#15335) Previously we ran a new process for every yaml file. yamllint can just take in a list of files to run, and handles this much more efficiently. On my machine, this broguht runtime from 75s to 15s. * minor galley component test cleanup (#15348) * Update KinD e2e test suite (#15308) * Update KinD e2e test suite * Set imagePullPolciy=Never per KinD docs * Fix image loading -- before it was only loading the last image not all of them * Set ARTIFACTS_DIR so the script can be run locally * Fix shellcheck * Fix accesslog integration tests (#15387) * Fix accesslog integration tests The log command was only getting the last 10 results, so it was missing the logs it was looking for. Additionally, cleaned up the error message to expose what log was actually missing rather than "one of these 3 logs was missing" * Get all logs * Deflake Redisquota Fixed Window (#14958) In the flakes, test fails as if the ratelimit rule has not been applied. Adding a retry, so as to give change for the rules to sync in properly Format the files Send some initial traffic to boot up the system. This had helped ratelimit tests to be more stable in old framework Dont change defaultlessthanoverride test as it is not flaky in postsubmits * Add cert expir time into pushed certs (#15336) * add cert expir time * add debug log * add debug log * remove debug log * revise * revise * format * revise * lint and format * revise * fix tests * lint * remove waring from yamllint (#15353) * Use docker.push instead of push in prow tests (#15139) The push command also does some installgen stuff which wastes 5+ minutes. * Standardize and increase E2E timeout (#15295) * fix a typo (#15368) * add myself to owner file (#15391) * add myself to owner file * update * Fully qualifies images names for all Istio sample charts. (#15195) Fixes: #14237. Signed-off-by: Jason Clark <jason.clark@ibm.com> * Cleanup unused prow scripts (#15389) These scripts are no longer needed; the prow just just directly call the targets. * update istio api and tidy (#15393) * Fixes #12873. Add support for Sidecar.OutboundTrafficPolicy to configure outbound traffic policy individually per cluster instead of on a cluster global scope (#15257) * code clean (#15282) * code clean * fix ut * decouple webhook configuration reconciliation (#12571) * decouple webhook configuration reconciliation Signed-off-by: clyang82 <clyang@cn.ibm.com> * remove unused param Signed-off-by: clyang82 <clyang@cn.ibm.com> * Address review comments * try to fix TestJobComplete flake (#15398) * try to fix TestJobComplete flake * makes curl in a loop * fix sh loop * Add cloudfoundry target for prow (#15404) * Set tail to high number for access log test (#15395) A prior commit was settting this to -1, which apparently doesn't work on all versions of kubectl and wasn't caught because the test is not required. Setting this to a high number will work on all versions. * Reenable mixer test (Fix #12750) (#14821) * Fix #12750 Make TestIngessToPrometheus_ServiceMetric less flaky by sending more than 1 productpage request.

These tests have migrated to istio/tools which has expanded far beyond this and kept up to date. * Stackdriver tracer: part I, generate bootstrap given meshconfig (#15345) * Add Stackdriver tracer thru OC * update go.mod for tests * Add basic default Grafana dashboard for Citadel [Issue 15228] (#15297) * Add basic Citadel dashboard with performance metrics, secret-controller metrics, general Citadel metrics, and error metrics * Add axis labels, remove duplicated CPU metric query * Fix dashboard row sizing stretch fit * Add back test target to circleci nightly (#15384) We previously added back some targets to run on circleci nightly so we can compare to prow, but the test target was deleted so the tests are failing. This just adds the same test target back. * Fix misleading error message in pilot-agent (#15409) Previously this would log `error: <nil>` every time an exit was triggered which was confusing. This makes it so it is only logged when an error actually occurs. * Use envoy with symbol and add gdb, strace, pstack to docker image (#14483) * Fix junit on integration kind tests (#15436) * Revert "Use envoy with symbol and add gdb, strace, pstack to docker image (#14483)" (#15441) This reverts commit 5f0726987db5c383ccea77543ae0832ca4e8d6e7. * Remove GCP Deployment Manager support in installer (#15438) * Makes the release grab the actual latest version (#15449) * Remove Ansible as it is unmaintained (#15443) In the future if individuals wish to maintain Ansible installation, that would be fine. The environments WG sees the role of Ansible to handle mesh expansion automation. * Make invalid test configs valid k8s configs (#15447) Right now these configs were rejected by kubernetes before even reaching Galley validation on Kubernetes 1.15+. This change makes them valid from a kubernetes perspective, but still invalid from Galley perspective. * Update pilot service registry aggregate controller to use rlock (#14953) * Add myself to pilot e2e (#15289) * Adapt e2e-suite.sh to allow execution with existing cluster (#15402) Add dummy comment to retrigger test.

This is a stepping stone to removing the old EDS legacy code entirely * Fix FQDN for docker using test framework (#15590) * Fix FQDN for docker using test framework In an attempt to get the trafficshifting test running natively, I found there was an issue with the FQDN construction. The kube component has the domain set to "svc.cluster.local", which is not really true, the domain is just "cluster.local" but it works fine because pilot-agent is actually using "cluster.local" for the domain. For docker this works differently, and we are creating configs for "foo.ns.cluster.local" which is not the correct service. This change makes the domain "cluster.local" everywhere, and adds the .svc. part everywhere it is needed. Additionally, it enables the trafficshifting test using docker, which works with this change. * Fix unit tests, disable native trafficshift * Don't produce duplicate wildcard host matches (#15628) Currently, if there are two https services, both will attempt to create this wildcard listener. Later, one of them will be rejected and logged as an outbound conflict. With this change we check to make sure that not only does the filter chain we are building not already have a wildcard, but the existing listener also does not have a wildcard. * cluster: fix original dst cluster type (#15613) * fix original dst cluster type Signed-off-by: Rama Chavali <rama.rao@salesforce.com> * minor doc * gaurd with enable redis flag Signed-off-by: Rama Chavali <rama.rao@salesforce.com> * rbac: refactor with better modular and unit tests (#15508) * refactor authz plugin to security package * address comments * move v1/v2 code to separate directory * fix lint * Don't report send error for expected errors (#15636) Right now a metric is incremeneted for every send error. The vast majority of the time this error is just due to standard operations with the connection closing while sending. This masks real errors. Once https://github.com/istio/istio/pull/15476 is merged and we have these errors displayed more prominently, we will not want to display these false positives. * fix stackdriver adapter getting shutdown (#15612) * Update license checker to use modules instead of packages (#15595) * Update license checker to use modules instead of packages * Add those modules with no license file to missing license output * Update to license path based on mod cache from URL and add knownUnknownLicenses * Additional logging to help determine failure point * Update to latest istio/api version (#15657) Annotations have been updated to clearly indicate alpha-level annotations. Also added annotations for synthetic service entries. * Add log dumping to kind to help debug integration test failures (#15637) * Retry and increase log level on kind creation We are seeing lots of flakes due to kind failing to create the cluster. This adds retries to cluster creation, and increase the log level so we can help root cause the issue. * Fix retry and shellcheck * Remove retries, dump logs * retain cluster * Build only images needed for tests (#15642) * Add sample traffic conformance tests (#15172) * Add minimal traffic conformance tests * Fix vendor * move 3rd party images to values (#14815) * refactor the rbac integ tests to reduce test time (#15643) * refactor the rbac integ tests to reduce test time 1) Puts all tests in the same package (main_test.go) to reuse the same Istio cluster and avoid creating/deleting the Istio cluster multiple times. Each test case will deploy the RBAC policy in their own namespace. 2) Do not wait for 60 seconds in each test case. The RunRBACTest() function will just retry for 10 times. So if there is any delay in policy propagation, it should be covered by the retry already, so it doesn't make too much sense to wait for another 60 seconds. * tweak the retry delay from 1.0 to 0.5 seconds and timeout from 10 seconds to 15 seconds * Reduce Galley unit test flakes (#15667) These tests fail sometimes due to trying to use a port that is already in use (9876). * enable multiple Set-Cookie headers (#15581) * enable multiple Set-Cookie headers - split DirectHttpResponse handling to its own function (ease testing) - split Set-Cookie header to multiple APPEND directives * add test for duplicate set-cookie header in directive * Add version suffix for crd jobs (#15677) * add version suffix for crds creation jobs. * update crds job names. * Refactor pilot dashboard to improve key metric visibility (#15665) * fix(pilot dash): refactor pilot dash to improve ux * Additional improvements * Table for the no known endpoints * More envoy stats, like connection failures and XDS size * exclude values from dashboard test * Fix quotes * fix wrong italic format (#15655) * fix wrong italic format * fix wrong italic format * fix wrong italic format * fix wrong italic format * fix wrong italic format * fix wrong italic format * Update config URL (#15153) Old link 404s * Add support for specify redirectCode in HTTPRoute (#15650) * Mark redis policy tests as flaky (#15687) * Fix kiali upgrade issue (#15690) Signed-off-by: Chun Lin Yang <clyang@cn.ibm.com> * Update versions field in crds definition.

Skipping setup or image building is useful for running locally. * Add a Dockerfile linter to our tests (#15484) * Hadolint first pass Decided to ignore a lot of message by default.

If CI/lint pass on this, we need to submit the check_dockerfile.sh to istio/common_files * Use bash * Fix shellcheck * Fix commonfile linter * Address @rlenglet 's comments * Forgot to remove ignore in previous commit * Refactor pilot test organization (#15608) * Refactor pilot test organization Prior to this change we had a package per test, making an unneccesary number of istio install/teardowns. Any test without a special set up can just be in the top level pilot package. This required some changes to the existing test in the top level (for some reason it was blocking the Close() method when it wasn't using the "new style" of tests) and some improved error reporting for trafficshifting. * Add license * Optimize contextgraph batch send algorithm (#15689) * Optimize contextgraph batch send algorithm This function attempts to split the request size to be the largest possible request that is smaller than the request size limit. It did this by linearly checking size(list[:n]), size(list[:n-1])... This ends up being extremely slow, because proto.size is not a very cheap operation for such large objects. In the case of racetests, this test was taking over 5 minutes sometimes. This modifies the algorithm to do a binary search for the optimal request; behavior should be the same. With this change: BenchmarkSendBatch/Size2-8 500000 3042 ns/op BenchmarkSendBatch/Size200-8 10000 135250 ns/op BenchmarkSendBatch/Size20000-8 30 52180768 ns/op Without this change BenchmarkSendBatch/Size2-8 500000 3082 ns/op BenchmarkSendBatch/Size200-8 10000 140837 ns/op BenchmarkSendBatch/Size20000-8 1 7999998085 ns/op This represents a 150x improvement on large request sizes and a negligible change for small requests Alternatively, if we don't care about the performance of this function, we can disable it in the racetests and leave this code as is. * Linear search by looking at individual size New benchmark: BenchmarkSendBatch/Size2-8 500000 3199 ns/op BenchmarkSendBatch/Size200-8 10000 138123 ns/op BenchmarkSendBatch/Size20000-8 100 24098886 ns/op This represents a 2x improvement over the previous commit and 300x improvement over the original * Look at size of message only once * Don't undershoot by one * Enable XDS marshalling to Any by default (#15632) This feature improves pilot performance substantially, but was disabled by default due to some proxy CPU regressions we were seeing. Since some Envoy changes we have been unable to reproduce since then. This will still be able to be turn off if issues do arise, but for now it seems safe to enable this by default. * Fix race condition in adsc client (#15771) CloseSend and Send cannot be called concurrently, which is possible and does happen in our tests, failing racetests. CloseSend is NOT required and also doesn't actually close the stream (but we do that in the next line anyways). See https://github.com/grpc/grpc-go/issues/2927 for details. * Fix: Consul high CPU usage (#15509) (#15510) * Fix: Consul high CPU usage (#15509) Add cache to avoid repeated remote calls to Consul catalog REST APIs Signed-off-by: Huabing Zhao <zhaohuabing@gmail.com> * fix race test Signed-off-by: Huabing Zhao <zhaohuabing@gmail.com> * move private methods down Signed-off-by: Huabing Zhao <zhaohuabing@gmail.com> * Generates sha256 for each istioctl archive published to GCS.

However, this caused issues, because we actually do want to modify - in particular, we sort the configs. Freezing + sorting can lead to obscure segmentation faults due to the freeze library using unsafe pointers, which was causing test failures. * Fix TestWorkloadAgentRefreshSecret racetest failure (#15794) * Split out common config items from Pilot (#15634) * Added TCP telemetry for BlackHole/Passthrough cluster (#15512) * Added telemetry for BlackHole/Passthrough cluster Fixes: #14664 Implements partial fix for #7669 * Updated pluging interface with OnVirtualListener method * Updated HTTP routes plugins for default clusters * Fix and update integration test * Change function name to onVirtualOutboundListener * Add destination service name for BlackHole/Passthrough * Created const for Passthrough/BlackHole route names * Change pkg/model to pkg/config * Fix TestServerSource race condition (#15799) If we set the desired error after we start the stream, the stream could have a real error before we get to setting the error. * Disable Test_KubeSecretController in racetest (#15769) * Make PushQueue test less flaky (#15786) The previous test depended on ordering of goroutines which is not reliable. It would consistently fail when running repeatedly. This change refactors the test to provide more coverage while not relying on any undefined ordering. * Fix metrics proxy port (#15807) * Cleanup makefile and prow scripts (#15685) * Remove junit for lint, set pipefail once * Remove ARTIFACTS_DIR and special junit outputs * Fix racetest junit * refactor listener.go (#15828) * enable locality weighted lb by default (#15014) * enable locality weighted lb by default * fix lint * fix ut * update mesh config helm template * revert * fixes for markdown style and typos (#15816) * Fix consul monitoring test flakes (#15821) Previously, the tests would wait for some period of time and check if it got any updates. This timing sensitive test fails often when CPU is throttled or slow, especially in -race or coverage mode. Additionally, one of the tests depended on the order of a map which is undefined. This change sorts the map output to be deterministic and changes the test to poll for success rather than wait and check. * rbac: remove the deprecated RBAC mixer adapter (#15675) * fixed typo: you-project => your-project (#15812) * Fix port collision on the Ctrlz component tests. (#15836) * Revert "multi-cluster panic fix (#15700)" (#15830) This reverts commit 0c93b9d75536b3134888b89edbcf04d35ec82054. * Fix testing flags showing up in release binaries (#15797) * Move test helper to test package * add test * Skip tests in codecov * Revert "Move test helper to test package" This reverts commit 1ed6cec3fe888e7851f5e050bc480e86035bdddb. * Replace testing with interface * Cleanup and properly document pilot env vars (#15801) * Cleanup and properly document pilot env vars Currently most of our environment variables are undocumented, and some also use the wrong types. This makes it very confusing because you can set FOO=false and it actually turns on FOO. This change cleans up these cases, and adds documentation to most of the variables used in pilot. * Fix errors * Upgrade kiali (#15372) * upgrade kiali Signed-off-by: clyang82 <clyang@cn.ibm.com> * upgrade kiali to 1.1 * Avoid inject panic with corner case (#15840) Signed-off-by: clyang82 <clyang@cn.ibm.com> * Make ServiceEntry follow Sidecar isolation (#13631) * Change hostname resolution to follow Sidecar See the design doc for more details https://docs.google.com/document/d/15-PU9O22Pb0qTzCfwK2hjwNTcb-CqFuw8JnIgwK3EIM/ This PR changes the behavior of Pilot when the same hostname is found in multiple namespaces (due to ServiceEntries). Previously, the behavior was undefined -- in some cases we selected an arbitrary service while in others we selected all services. The new behavior will always select a single namespace for a given hostname. If a hostname exists in multiple namespaces, one will be determined by the Sidecar scope. If the sidecar imports multiple namespaces with the same hostname, an arbitrary one will be chosen, favoring the proxies namespace if possible. * Get rid of dummy sidecar * Make InstancesByPort take a Service instead of host This is primarily meant to enable https://github.com/istio/istio/pull/13631, which will require the full Service * Make instances by port use proper namespace selection * Clean up dead code * Fix rebase errors * Various improvements to pilot tests to make them more hermetic (#15847) * Make listener_test use open port * Make appprobe test poll until ready * Make pilot-agent role tests not depend on global state * Enable skipped test with resolved issue * Integration tests for webhook in galley scaling scenarios (#15841) * Integ test for webhook behavior when scaling galley * integ test to verify webhook config deletion when galley uninstalled * PR review fixups * Move galley webhook tests into their own suite * Use subtests * Increase delay to wait for webhook reconciliation to act * Try fetch secret directly in case a secret is requested but cache doe… (#15672) * Try fetch secret directly in case a secret is requested but cache doesn't have it somehow * Don't put secret directly fetched from API call to cache * Mixer: add tests for direct HTTP response (#15781) * add test for direct HTTP response - status code - body setting - header manipulation * gofmt changes * Initial infinite request loop fix (#15833) * Add POD_IP match to prevent infinite traffic loops * fix lint * Disable for cloudfoundry test * Precompute filter * Add integration test * Also report number of virtual services known to pilot.

This means that if a timeout occured, there would be nothing trying to read from `done`, which would cause it to block indefinitely. Because of this, every timeout resulted in a goroutine to be leaked. Now it is buffered so the send can occur even after the timer completes.
