# Makefile for building jce.jar and the various cryptographic strength

# policy jar files.

#

#

# (The terms "OpenJDK" and "JDK" below refer to OpenJDK and Sun JDK builds

# respectively.)

#

# JCE builds are very different between OpenJDK and JDK.  The OpenJDK JCE

# jar files do not require signing, but those for JDK do.  If an unsigned

# jar file is installed into JDK, things will break when the crypto

# routines are called.

#

# This Makefile does the "real" build of the JCE files.  There are some

# javac options currently specific to JCE, so we recompile now to make

# sure any implicit compilations didn't use any incorrect flags.

#

# For OpenJDK, the jar files built here are installed directly into the

# OpenJDK.

#

# For JDK, the binaries use pre-built/pre-signed/pre-obfuscated binary

# files stored in the closed workspace that are not shipped in the

# OpenJDK workspaces.  We still build the JDK files here to verify the

# files compile, and in preparation for possible signing and

# obfuscation.  Developers working on JCE in JDK must sign the JCE files

# before testing: obfuscation is optional during development.  The JCE

# signing key is kept separate from the JDK workspace to prevent its

# disclosure.  The obfuscation tool has not been licensed for general

# usage.

#

# SPECIAL NOTE TO JCE/JDK developers:  The source files must eventually

# be built, obfuscated, signed, and the resulting jar files *MUST BE

# CHECKED INTO THE CLOSED PART OF THE WORKSPACE*.  This separate step

# *MUST NOT BE FORGOTTEN*, otherwise a bug fixed in the source code will

# not be reflected in the shipped binaries.  The "release" target should

# be used to generate the required files.

#

# There are a number of targets to help both JDK/OpenJDK developers.

#

# Main Targets (JDK/OPENJDK):

#

#     all/clobber/clean		The usual.

#				    If OpenJDK, installs

#					jce.jar/limited policy files.

#				    If JDK, installs prebuilt

#					jce.jar/limited policy files.

#

#     jar			Builds/installs jce.jar

#				    If OpenJDK, does not sign

#				    If JDK, tries to sign

#

# Other lesser-used Targets (JDK/OPENJDK):

#

#     build-jar			Builds jce.jar (does not sign/install)

#

#     build-policy		Builds policy files (does not sign/install)

#

#     install-jar		Alias for "jar" above

#

#     install-limited		Builds/installs limited policy files

#				    If OpenJDK, does not sign

#				    If JDK, tries to sign

#     install-unlimited		Builds/nstalls unlimited policy files

#				    If OpenJDK, does not sign

#				    If JDK, tries to sign

#

# Other targets (JDK only):

#

#     sign			Alias for sign-jar and sign-policy

#	  sign-jar		Builds/signs jce.jar file (no install)

#	  sign-policy		Builds/signs policy files (no install)

#

#     obfus			Builds/obfuscates/signs/installs jce.jar

#

#     release			Builds all targets in preparation

#				for workspace integration.

#

#     install-prebuilt		Installs the pre-built jar files

#

# This makefile was written to support parallel target execution.

#

# JCE building is somewhat involved.

#

# OpenJDK:  Since we do not ship prebuilt JCE files, previous compiles

# in the build may have needed JCE class signatures.  There were then

# implicitly built by javac (likely using the boot javac).  While using

# those class files was fine for signatures, we need to rebuild using

# the right compiler.

#

# JDK:  Even through the jce.jar was previously installed, since the

# source files are accessible in the source directories, they will

# always be "newer" than the prebuilt files inside the jar, and thus

# make will always rebuild them.  (We could "hide" the JCE source in a

# separate directory, but that would make the build logic for JDK and

# OpenJDK more complicated.)

#

# Thus in either situation, we shouldn't use these files.

#

# To make sure the classes were built with the right compiler options,

# delete the existing files in $(CLASSBINDIR), rebuild the right way in a

# directory under $(TEMPDIR), then copy the files back to

# $(CLASSBINDIR).   Building in $(TEMPDIR) allows us to use our make

# infrastructure without modification:  .classes.list, macros, etc.
