* Issue #68 added request context scope * Issue #68 added request context scope * Issue #68 added skeleton Logging Handler * Issue #68 work in progress * Issue #68 work in progress * working implementation using a threadlocal to stop looping * Issue #68 update to latest google-cloud-java LoggingHandler * Issue #68 Updated to latest gcloud API removed copied LoggingHandlers removed instanceid from monitored resource * Issue #68 Use same labels as nginx * Issue #68 Code cleanups after review * Issue #68 Removed stackdriver logging, so this just configures JUL to capture the traceid and log to stderr * renamed traceid to traceId * gcloud api not currently used * Tunnel traceId in parameters #68 * Simplified with traceId lookup in formatter #68 * Use 8.2 beta stackdriver * Improved formatting * use logger name rather than source * run jetty from the webapp working directory so logging configuration may be relative * Testing logging Test googleapis/google-cloud-java#1535 and jetty-9.4.1-SNAPSHOT * use released 9.4.1 * Issue #68 minor clean ups * Do not CD to non existant directory * improved README * fixed Cloud SDK * Released beta of google-cloud-logging * updated google-cloud API to 0.8.3-beta * added remote test to check logging * Stackdriver logging testing improved comments check for traceid * upgrade to 0.9.2 * Test for zone * upgrade to 10.0 gcloud API * enable gae module only of GAE_INSTANCE environment variable is set * improved gae.mod documentation * GCP module Rename gae module and configuration to gcp Split the jetty.commands into jetty.commands and gcp.commands moved commands file to jetty-base/config-scripts updated setup-env-ext to run the gcp.commands when image is run with a GAE_INSTANCE set * fixed warnings * turn off stackdriver logging by default. Added instructions to enable. * Updates Update to latest openjdk-runtime with setup-env.d Update to latest jetty release * Use the PLATFORM env var * Improved jetty startup Added JETTY_PROPERTIES, JETTY_MODULES_ENABLE & JETTY_MODULES_DISABLE Removed duplicate code fron 50-jetty.bash * use launcher URL * Trimmed GCP specific configuration * Added structure tests for jetty setup script Also fixed unpack bug found as a result * Support passing just args * fix merge * Fixed test workspace paths for cloud build * review feedback * working directory is the root webapp * Improve handling of various types of command line. Fixed problem with handling of command line like "ls /var" Requires duplication of test for java from openjdk-runtime docker-entrypoint.bash, which should be modified to avoid the duplication. * upgrade cgloud API version to 0.13.0-beta * use package target * tested with FINE log level * Simplify entrypoint args processing The $@ arg array is kept complete between all scripts. * remove debug * remove debug * Test that the logging dependencies are hidden from webapp classpath * update README.md with instructions to keep INFO level on io.grpc.netty.level=INFO * Updated to lasted openjdk-runtime * fixed classloader test * fixed TODO * Update to jetty 9.4.5 and gcloud 1.0.1-SNAPSHOT * upgraded to gcloud-logging 1.0.1 * turn off debug * updated README for latest 1.0.1 gcloud-logging * update classpath exclusion \o/
