# BundleUtilities
# ---------------
#
# Functions to help assemble a standalone bundle application.
#
# A collection of CMake utility functions useful for dealing with .app
# bundles on the Mac and bundle-like directories on any OS.
#
# The following functions are provided by this module:
#
# ::
#
# fixup_bundle
# copy_and_fixup_bundle
# verify_app
# get_bundle_main_executable
# get_dotapp_dir
# get_bundle_and_executable
# get_bundle_all_executables
# get_item_key
# clear_bundle_keys
# set_bundle_key_values
# get_bundle_keys
# copy_resolved_item_into_bundle
# copy_resolved_framework_into_bundle
# fixup_bundle_item
# verify_bundle_prerequisites
# verify_bundle_symlinks
#
# Requires CMake 2.6 or greater because it uses function, break and
# PARENT_SCOPE. Also depends on GetPrerequisites.cmake.
#
# ::
#
# FIXUP_BUNDLE(<app> <libs> <dirs>)
#
# Fix up a bundle in-place and make it standalone, such that it can be
# drag-n-drop copied to another machine and run on that machine as long
# as all of the system libraries are compatible.
#
# If you pass plugins to fixup_bundle as the libs parameter, you should
# install them or copy them into the bundle before calling fixup_bundle.
# The "libs" parameter is a list of libraries that must be fixed up, but
# that cannot be determined by otool output analysis. (i.e., plugins)
#
# Gather all the keys for all the executables and libraries in a bundle,
# and then, for each key, copy each prerequisite into the bundle. Then
# fix each one up according to its own list of prerequisites.
#
# Then clear all the keys and call verify_app on the final bundle to
# ensure that it is truly standalone.
#
# ::
#
# COPY_AND_FIXUP_BUNDLE(<src> <dst> <libs> <dirs>)
#
# Makes a copy of the bundle <src> at location <dst> and then fixes up
# the new copied bundle in-place at <dst>...
BundleUtilities: error if fixup_bundle_item called on non-embedded item Also, improve the documentation of the fixup_bundle and fixup_bundle_item functions to clarify that plugin type "libs" need to be copied into the bundle *before* calling fixup_bundle. Commit e93a4b4d3421ced7b8c852b76c0dcb427f798df8 changed the way that the libs parameter to fixup_bundle is interpreted. Before the commit, the libs were copied into the bundle first and then fixed up. After the commit, the copy was skipped, assuming the libs were in the bundle in the first place, and then the fixups occurred as before. However, before the commit, it was possible to name a lib from outside the bundle, and have it copied in and then fixed up. Its resolved embedded name was always inside the bundle before. After, its resolved embedded name was just the same as its resolved name, which is in its original location, and not necessarily inside the bundle. This manifested itself as a problem with the ParaView call to fixup_bundle and its many plugins. Previously, ParaView had simply passed in the list of plugin file names as they existed in the build tree, and left the copying into the bundle up to the fixup_bundle function. When built with CMake 2.8.3 (the first version to contain the above named commit) the fixup_bundle call would inadventently fixup libraries in the build tree, not libraries that were in the bundle. Furthermore, the plugins would not be in the final bundle. This points out the fact that the fix for the bugs made by the above commit was a backwards-incompatible change in behavior. This commit makes it an error to try to fixup an item that is not already inside the bundle to make the change in behavior apparent to folks who were depending on the prior copy-in behavior: now, they should get an error, and hopefully, reading the new and improved documentation, should be able to resolve it in their projects by adding code to install or copy in such libraries prior to calling fixup_bundle. Whew.

#
# ::
#
# VERIFY_APP(<app>)
#
# Verifies that an application <app> appears valid based on running
# analysis tools on it. Calls "message(FATAL_ERROR" if the application
# is not verified.
#
# ::
#
# GET_BUNDLE_MAIN_EXECUTABLE(<bundle> <result_var>)
#
# The result will be the full path name of the bundle's main executable
# file or an "error:" prefixed string if it could not be determined.
#
# ::
#
# GET_DOTAPP_DIR(<exe> <dotapp_dir_var>)
#
# Returns the nearest parent dir whose name ends with ".app" given the
# full path to an executable. If there is no such parent dir, then
# simply return the dir containing the executable.
#
# The returned directory may or may not exist.
#
# ::
#
# GET_BUNDLE_AND_EXECUTABLE(<app> <bundle_var> <executable_var> <valid_var>)
#
# Takes either a ".app" directory name or the name of an executable
# nested inside a ".app" directory and returns the path to the ".app"
# directory in <bundle_var> and the path to its main executable in
# <executable_var>
#
# ::
#
# GET_BUNDLE_ALL_EXECUTABLES(<bundle> <exes_var>)
#
# Scans the given bundle recursively for all executable files and
# accumulates them into a variable.
#
# ::
#
# GET_ITEM_KEY(<item> <key_var>)
#
# Given a file (item) name, generate a key that should be unique
# considering the set of libraries that need copying or fixing up to
# make a bundle standalone. This is essentially the file name including
# extension with "." replaced by "_"
#
# This key is used as a prefix for CMake variables so that we can
# associate a set of variables with a given item based on its key.
#
# ::
#
# CLEAR_BUNDLE_KEYS(<keys_var>)
#
# Loop over the list of keys, clearing all the variables associated with
# each key. After the loop, clear the list of keys itself.
#
# Caller of get_bundle_keys should call clear_bundle_keys when done with
# list of keys.
#
# ::
#
# SET_BUNDLE_KEY_VALUES(<keys_var> <context> <item> <exepath> <dirs>
# <copyflag>)
#
# Add a key to the list (if necessary) for the given item. If added,
# also set all the variables associated with that key.
#
# ::
#
# GET_BUNDLE_KEYS(<app> <libs> <dirs> <keys_var>)
#
# Loop over all the executable and library files within the bundle (and
# given as extra <libs>) and accumulate a list of keys representing
# them. Set values associated with each key such that we can loop over
# all of them and copy prerequisite libs into the bundle and then do
# appropriate install_name_tool fixups.
#
# ::
#
# COPY_RESOLVED_ITEM_INTO_BUNDLE(<resolved_item> <resolved_embedded_item>)
#
# Copy a resolved item into the bundle if necessary. Copy is not
# necessary if the resolved_item is "the same as" the
# resolved_embedded_item.
#
# ::
#
# COPY_RESOLVED_FRAMEWORK_INTO_BUNDLE(<resolved_item> <resolved_embedded_item>)
#
# Copy a resolved framework into the bundle if necessary. Copy is not
# necessary if the resolved_item is "the same as" the
# resolved_embedded_item.
#
# By default, BU_COPY_FULL_FRAMEWORK_CONTENTS is not set. If you want
# full frameworks embedded in your bundles, set
# BU_COPY_FULL_FRAMEWORK_CONTENTS to ON before calling fixup_bundle. By
# default, COPY_RESOLVED_FRAMEWORK_INTO_BUNDLE copies the framework
# dylib itself plus the framework Resources directory.
#
# ::
#
# FIXUP_BUNDLE_ITEM(<resolved_embedded_item> <exepath> <dirs>)
#
# Get the direct/non-system prerequisites of the resolved embedded item.
# For each prerequisite, change the way it is referenced to the value of
# the _EMBEDDED_ITEM keyed variable for that prerequisite. (Most likely
# changing to an "@executable_path" style reference.)
#
# This function requires that the resolved_embedded_item be "inside" the
# bundle already. In other words, if you pass plugins to fixup_bundle
# as the libs parameter, you should install them or copy them into the
# bundle before calling fixup_bundle. The "libs" parameter is a list of
# libraries that must be fixed up, but that cannot be determined by
# otool output analysis. (i.e., plugins)
#
# Also, change the id of the item being fixed up to its own
# _EMBEDDED_ITEM value.
#
# Accumulate changes in a local variable and make *one* call to
# install_name_tool at the end of the function with all the changes at
# once.
#
# If the BU_CHMOD_BUNDLE_ITEMS variable is set then bundle items will be
# marked writable before install_name_tool tries to change them.
#
# ::
#
# VERIFY_BUNDLE_PREREQUISITES(<bundle> <result_var> <info_var>)
#
# Verifies that the sum of all prerequisites of all files inside the
# bundle are contained within the bundle or are "system" libraries,
# presumed to exist everywhere.
#
# ::
#
# VERIFY_BUNDLE_SYMLINKS(<bundle> <result_var> <info_var>)
#
# Verifies that any symlinks found in the bundle point to other files
# that are already also in the bundle... Anything that points to an
# external file causes this function to fail the verification.

This commit makes it an error to try to fixup an item that is not already inside the bundle to make the change in behavior apparent to folks who were depending on the prior copy-in behavior: now, they should get an error, and hopefully, reading the new and improved documentation, should be able to resolve it in their projects by adding code to install or copy in such libraries prior to calling fixup_bundle. Whew.

BundleUtilities: error if fixup_bundle_item called on non-embedded item Also, improve the documentation of the fixup_bundle and fixup_bundle_item functions to clarify that plugin type "libs" need to be copied into the bundle *before* calling fixup_bundle. Commit e93a4b4d3421ced7b8c852b76c0dcb427f798df8 changed the way that the libs parameter to fixup_bundle is interpreted. Before the commit, the libs were copied into the bundle first and then fixed up. After the commit, the copy was skipped, assuming the libs were in the bundle in the first place, and then the fixups occurred as before. However, before the commit, it was possible to name a lib from outside the bundle, and have it copied in and then fixed up. Its resolved embedded name was always inside the bundle before. After, its resolved embedded name was just the same as its resolved name, which is in its original location, and not necessarily inside the bundle. This manifested itself as a problem with the ParaView call to fixup_bundle and its many plugins. Previously, ParaView had simply passed in the list of plugin file names as they existed in the build tree, and left the copying into the bundle up to the fixup_bundle function. When built with CMake 2.8.3 (the first version to contain the above named commit) the fixup_bundle call would inadventently fixup libraries in the build tree, not libraries that were in the bundle. Furthermore, the plugins would not be in the final bundle. This points out the fact that the fix for the bugs made by the above commit was a backwards-incompatible change in behavior. This commit makes it an error to try to fixup an item that is not already inside the bundle to make the change in behavior apparent to folks who were depending on the prior copy-in behavior: now, they should get an error, and hopefully, reading the new and improved documentation, should be able to resolve it in their projects by adding code to install or copy in such libraries prior to calling fixup_bundle. Whew.
