GEODE-10327: Overhaul GfshRule to kill processes and save artifacts for
failures (#7571)
PROBLEM
Tests that use GfshRule leave behind orphaned processes and do not save
artifacts for debugging failures.
SOLUTION
GfshRule needs to cleanup all processes it forks. It also needs to save off all
runtime artifacts such as logging, stats, pid files, diskstores to enable
debugging of test failures.
DETAILS
Enhance GfshRule and modify all tests using it for proper debugging and to
prevent test pollution.
Overhaul of GfshRule:
* kill ALL geode processes during cleanup
* use FolderRule to ensure all logs and files are properly saved off when a
test fails
* extract GfshExecutor from JUnit rule code
* GfshExecutor allows a test to use any number of Geode versions with just one
GfshRule
* add Gfsh log level support for easier debugging
* add support for new VmConfiguration to allow control over Geode and Java
versions
* overhaul API of GfshRule and companion classes for better consistency and
design
New FolderRule:
* replaces TemporaryFolder and saves off all content when a test fails
* creates root directory under the gradle worker instead of under temp
Update HTTP session caching module tests:
* use new FolderRule to save all artifacts when a test fails
* use nio Paths for filesystem variables
Update acceptance and upgrade tests that use GfshRule:
* use new improved GfshRule and GfshExecutor
* use new FolderRule instead of TemporaryFolder to save all artifacts when a
test fails
* use --disable-default-server in tests with no clients
* fix flakiness of many tests by using random ports instead of default or
hardcoded port values
* reformat GfshRule API usage in tests to improve readability and consistency
* add GfshStopper to provide common place to await process stop (stop
locator/server is async so restarting with same ports is very prone to hitting
BindExceptions)
Update ProcessUtils:
* extract NativeProcessUtils and make it public for direct use
* rename InternalProcessUtils as ProcessUtilsProvider and move to its own class
* rethrow IOExceptions as UncheckedIOExceptions
* fix flakiness in NativeProcessUtilsTest by moving findAvailablePid into test
method
Minor changes:
* improve code formatting and readability
* convert from old io File to nio Path APIs as much as possible
* close output streams to fix filesystem issues on Windows
Fixes flaky test tickets:
* DeployJarAcceptanceTest GEODE-9615
* possibly other tests that uses GfshRule
NOTES
The jdk8, jdk17 and windows labels were used to run tests on more environments.
This PR contains mostly test and framework changes. The only product code
altered is ServerLauncher and several classes in
org.apache.geode.internal.process, all of which is in geode-core.
