Hi Alan, Mandy,
Here is the next round of this change:
It now also has tests which don't require objcopy to be present on test
machines as well as being integrated with --strip-debug (once JDK-
8218913 is pushed). --list-plugins help output for --strip-native-
debug-symbols now reads:
Plugin Name: strip-native-debug-symbols
Description: Strip debug symbols from native libraries (if any).
This plugin requires at least one option:
objcopy: The path to the objcopy binary. Defaults to objcopy in PATH.
omit-debuginfo: Do not keep debug info files. Defaults to true.
keep-debuginfo[=<ext>]: Keep debug info files in <file>.<ext>.
Defaults to <file>.debuginfo
Examples: --strip-native-debug-symbols objcopy=/usr/bin/objcopy
Testing: jdk.jlink tests jdk/submit (ongoing), added tests:
Note: IntegrationTest needed a heap size bump as this now runs
StripNativeDebugSymbolsPluginTest on some systems. Especially with
--with-native-debug-symbols=internal builds this can eat some
Please let me know what you think.
