Hi Alejandro,

I don't think we need to rename make/hotspot_version file. It is still
used to set JVM's version string and not JDK's version.


Next assert message is not consistent with previous messages which use
"vm", I think it should be "vm" here too:

  DEBUG_ONLY(assert_digits(vm_build_num, offset, "wrong JDK build
number"));
we do not have hotspot build number anymore, so I think we should not
mention hotspot build numberls

Can we simple say "wrong build number"?

So you don't want update build number in make/*_version files? ;)
Yes, I see in your example of JPRT build VM does not have build number anymore.


Abstract_VM_Version::jvm_version() should include micro version. See
JVM_GetVersionInfo() in jvm.cpp and jvm_version_info in
jdk/src/share/javavm/export/jvm.h.
I added that here, is that what you are referring?
http://cr.openjdk.java.net/~amurillo/9/8030011/src/share/vm/runtime/vmStructs.cpp.udiff.html

http://cr.openjdk.java.net/~amurillo/9/8030011/src/share/vm/runtime/vm_version.hpp.udiff.html

No, I mean next code should encode micro version too:

 unsigned int Abstract_VM_Version::jvm_version() {
   return ((Abstract_VM_Version::vm_major_version() & 0xFF) << 24) |
          ((Abstract_VM_Version::vm_minor_version() & 0xFF) << 16) |
+         ((Abstract_VM_Version::vm_micro_version() & 0xFF) <<  8) |
          (Abstract_VM_Version::vm_build_number() & 0xFF);
 }



Use corresponding test in jdk for testing of these changes:

jdk/test/sun/misc/Version/Version.java
yeah, I run that test as part of jprt full builds,
That test handles both JDK and Hotspot express versions

Good.


jvm.h: Next comment is not accurate:

+    /* VM version string: JDK version string     */

If we build VM separately (for example, in JPRT) VM version will not
be JDK version in which VM is installed. It will take numbers either
from passed make parameters or from make/hotspot_version. I think it
should say:

+    /* VM version string follows the JDK release version naming
convention
+     * <major>.<minor>.<micro>-bxx[-<identifier>][-<debug_flavor>]

Based on your examples [-<identifier>][-<debug_flavor>] is still used
so it should be reflected in the comment.
Let me make that explicit.

Don't remove next comments from vm_version.cpp but fix it ("follow the
JDK release"):

-// HOTSPOT_RELEASE_VERSION must follow the release version naming
convention
-// <major_ver>.<minor_ver>-b<nn>[-<identifier>][-<debug_target>]
ok

You did not show default VM version example when VM is built locally
by engineer.
It will be similar to the hotspot only jprt build. There will be a
mismatch,
I tested by dropping the resulting libjvm  into a promoted build, so it
looks like this:

java version "1.9.0-ea"
Java(TM) SE Runtime Environment (build 1.9.0-ea-b01)
Java HotSpot(TM) 64-Bit Server VM (build 1.9.0-internal-debug, mixed mode)

okay



Please test that correct version string is constructed when you build
VM using make/build.sh, for example 'sh make/build.sh debug LP64=1'
Haven't tested that, thanks for pointing that out.

thank you


Next comment change in buildtree.make is not correct because
HOTSPOT_RELEASE_VERSION make parameter does not include
HOTSPOT_BUILD_VERSION:

-# HOTSPOT_RELEASE_VERSION - <major>.<minor>-b<nn> (11.0-b07)
+# HOTSPOT_RELEASE_VERSION - JRE_RELEASE_VERSION plus
HOTSPOT_BUILD_VERSION

see JPRT logs where HOTSPOT_BUILD_VERSION is set separately.
let me check that again

I think next change in make/defs.make is not safe (removing make
parameter) due to complexity of our builds:

-MAKE_ARGS += HOTSPOT_RELEASE_VERSION=$(HOTSPOT_RELEASE_VERSION)
I checked the code, and HOTSPOT_RELEASE_VERSION is only used in
vm_version.cpp,
so I think is fine to remove it. Note that if we keep it there, since
the JDK version string
sometimes might have time stamps, it may affect ccache,  that's why at
some point they
separated the options for vm_version.cpp from the options for other
components. See this
comment on vm,make:

# This is VERY important! The version define must only be supplied to
vm_version.o
# If not, ccache will not re-use the cache at all, since the version
string might contain
# a time and date.


I was concern that it will not be passed into nested make so that, for example, buildtree.make will not get it.




I know that windows build is mess. Please verify it carefully. For
example, you changed names JDK_*_VER to JDK_*_VERSION in def.make but
build.make uses them:

JDK_VER=$(JDK_MINOR_VER),$(JDK_MICRO_VER),$(JDK_UPDATE_VER),$(JDK_BUILD_NUMBER)

That was a typo. Note that I changed the left handside, so they were
incorrectly reassigning those.
The places were JDK_MINOR_VER is used, the value is read from
jdk_version (formerly hotspot_version)

Okay.

Thanks,
Vladimir


Thanks a lot for the feedback!

Please review this change to make the hotspot related output

webrev: http://cr.openjdk.java.net/~amurillo/9/8030011/
Bug: https://bugs.openjdk.java.net/browse/JDK-8030011

Note that we initially wanted to obtain more information from the repo
being built and add
it to the hotspot version output, but that will require changes in the
JPRT, so
we have decided to split the change in 2 bugs. One to make the
version match
(above webrev) and another one, an RFE, to add additional information
extracted from the repo.
Generally looks good, but I agree with David that the long lines
should be wrapped, and it might even be clearer to separate them into
two variables, e.g.,

JDK_VERSION_DEFS = -DJDK_MAJOR_VERSION="\"$(JDK_MAJOR_VERSION)\"" \
           -DJDK_MINOR_VERSION="\"$(JDK_MINOR_VERSION)\"" \
           ... other defs ...
VERSION_DEFS  = -DHOTSPOT_RELEASE_VERSION="\"$(HS_BUILD_VER)\"" \
        -DJRE_RELEASE_VERSION="\"$(JRE_RELEASE_VER)\"" \
        $(JDK_VERSION_DEFS)

Also the change to this part of vm.make differs between at least the
solaris version and the linux version (didn't check bsd or windows).
Please make them all consistent.

Note that in the current version of vm_version.cpp, there is no error
checking in product mode,
I was suggested to make that explicit.
I like the additional error checking.  I think you could eliminate the
4 copies of similar code with a function that does the checks and sets
the field, e.g.,

     void set_version_field(int * version_field, const char *
version_str,
               const char * const assert_msg) {
        if (version_str != NULL ...) {
     DEBUG_ONLY(assert_digits(version_str, assert_msg));
     *version_field = atoi(version_str);
        }
     }

Thanks John,
working on adding these changes and sanity testing

Thanks
