Project: Harmony
Issue Type: Bug
Components: DRLVM
Reporter: Vladimir Ivanov
Priority: Minor
Help on 'internal system property' should be available from command line.
Some time ago the option to specify 'system property' was updated but help for this properties was just removed.
Some commands were tried:
>java.exe -help
>java.exe -help properties
>java.exe -X
>java.exe -XX
but no one say about it.
Execution log:
>java -help

[jira] Updated: (HARMONY-3409) [drlvm][init] help on 'internal
system property' should be available from command line
Posted by "Vladimir Beliaev (JIRA)" <ji...@apache.org>.

Vladimir Beliaev updated HARMONY-3409:
--------------------------------------
Attachment: H3409.patch
Ok, I redo the patch a bit... Please use this recent version...
As was mentioned before there is "text duplication" while using LECHO - 1 striing is located in parse_arguments.cpp & duplicating string is located in harmony.properties resource file.
In fact a first string is never used (removing harmony.properties is "breaking drlvm configuration")... Another option is when harmoby.properties is localized incorrectly (some of string resources are missed) - but it is a localization bug which is to be reported but not workarounded...
So I've removed the first pack of help strings (from parse_arguments.cpp) after merging these strings with ones in harmoby.properties. Instead, parse_arguments.cpp contains the string like "Internal error - missed string resource".

Vladimir Beliaev commented on HARMONY-3409:
-------------------------------------------
So, there are two issues here:
1. add command line support for '-help properties' or/and '-Xhelp:props'
2. update 'print_vm_standard_properties' implementation.
Resolving a second issue seems to be not a big deal. Still I propose to remove the notion of propserties which should not be set from command line (they are to be placed in Dev Guide) + those properties which require deep understanding of scope (like jitrino options).
And first issue (support for '-help properties' or/and '-Xhelp:props') can't be solved w/o making 'generic launcher' (from 'classlib') to be DRLVM specific. Because:
- this generic launcher calls to JNI_CreateJavaVM if 'mainClass' is set or "help option" is defined
- the standard (generic) (supported by other VMs) "help options" are: ? -h -help -X
- JNI_CreateJavaVM does not accept 'mainClass'
- JNI_CreateJavaVM implemetation recognize "help option", prints a help & exits with '0'
- the launcher does not do a "main method invocation" after JNI_CreateJavaVM if 'mainClass' is NULL
So, if '-help properties' is defined in command line then the laucher considers 'properties' as 'mainClass', so only '-help' is passed to JNI_CreateJavaVM (no way to recognize it is '-help properties' but not just a '-help' case).
If '-Xhelp:prop' is defined in command line then the launcher does not recognize it is a 'help option' (it knows the standard ones only), looks for 'mainClass', does not find 'mainClass' & reports "wrong command line' w/o calling to JNI_CreateJavaVM...
The solution here is to make the launcher to recognize '-Xhelp:prop' as 'help option' but I think this would make this laucnher to have some DRLVM specific...

-------------------------------------------
One more solution is to creare a 'DRLVM options" documentation page at harmony.apache.org & provide the link as part of help output from '-X' option... I'm going to discuss this on dev-list...

[jira] Commented: (HARMONY-3409) [drlvm][init] help on 'internal
system property' should be available from command line
Posted by "Vladimir Beliaev (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HARMONY-3409?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12507206 ]
Vladimir Beliaev commented on HARMONY-3409:
-------------------------------------------
There is a mail thread on dev-list discussing the possible solutions:
http://mail-archives.apache.org/mod_mbox/harmony-dev/200706.mbox/%3c587698b80706200231s6581d426qadebc3b25fbe7385@mail.gmail.com%3e
The current decision is to keep system properties help at web pache on harmony.apache.org. There is such a page already:
http://wiki.apache.org/harmony/DrlvmCommandLineOptions
Still (according to decisiosn) it is to be moved to static html page (from Wiki):
http://harmony.apache.org/cmd_options.html
Thanks

[jira] Updated: (HARMONY-3409) [drlvm][init] help on 'internal
system property' should be available from command line
Posted by "Vladimir Beliaev (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HARMONY-3409?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Vladimir Beliaev updated HARMONY-3409:
--------------------------------------
Attachment: H3409.patch
Ok, here is the patch which:
- removed '-Xhelp:prop*' option processing - this a dead code
- removed '-help properties' notion from 'help output' - this options do not worh either
- cleaned up 'print_help_on_nonstandard_options' function based on list of currently
supported options (removed -Xjit & extended "wgat way a boolean property can be set)
- removed "print_vm_standard_properties" - the related content is available on web page now
- updated harmony.properties - the help text is ducplicated on both paser_arguments.cpp & this file
Thanks

[jira] Commented: (HARMONY-3409) [drlvm][init] help on 'internal

Vladimir Beliaev commented on HARMONY-3409:
-------------------------------------------
The affected DRLVM file is: <trunk>/working_vm/vm/vmcore/src/init/parse_arguments.cpp:
line 129-130:
" -help properties\n"
" help on system properties\n"
(so 'java -help properties' command line was supposed to be supported...)
line 376-386:
else if (begins_with(option, "-Xhelp:")) {
...
if (begins_with(arg, "prop")) {
(so 'java -Xhelp:properties' command line was supposed to be supported...)
line 221:
void print_vm_standard_properties()
(this method is implement but it has problems - some properties description are out of date, some properties should not be used by customers [like 'vm.jvmti.enabled' should not be set from command line]).

> Help on 'internal system property' should be available from command line.
> Some time ago the option to specify 'system property' was updated but help for this properties was just removed.
> Some commands were tried:
> >java.exe -help
> >java.exe -help properties
> >java.exe -X
> >java.exe -XX
> but no one say about it.
> Execution log:
> >java -help
> Usage: java [-options] class [args...]
> (to execute a method main() of the class)
> or java [-options] -jar jarfile [args...]
> (to execute the jar file)
> where options include:
> -classpath <class search path of directories and zip/jar files>
> -cp <class search path of directories and zip/jar files>
> A ';' separated list of directories, jar archives,
> and zip archives to search for class file
