 # Build System Changes for Android.mk Writers
 
+## `PRODUCT_HOST_PACKAGES` split from `PRODUCT_PACKAGES` {#PRODUCT_HOST_PACKAGES}
+
+Previously, adding a module to `PRODUCT_PACKAGES` that supported both the host
+and the target (`host_supported` in Android.bp; two modules with the same name
+in Android.mk) would cause both to be built and installed. In many cases you
+only want either the host or target versions to be built/installed by default,
+and would be over-building with both. So `PRODUCT_PACKAGES` will be changing to
+just affect target modules, while `PRODUCT_HOST_PACKAGES` is being added for
+host modules.
+
+Functional differences between `PRODUCT_PACKAGES` and `PRODUCT_HOST_PACKAGES`:
+
+* `PRODUCT_HOST_PACKAGES` does not have `_ENG`/`_DEBUG` variants, as that's a
+  property of the target, not the host.
+* `PRODUCT_HOST_PACKAGES` does not support `LOCAL_MODULE_OVERRIDES`.
+* `PRODUCT_HOST_PACKAGES` requires listed modules to exist, and be host
+  modules. (Unless `ALLOW_MISSING_DEPENDENCIES` is set)
+
+This is still an active migration, so currently it still uses
+`PRODUCT_PACKAGES` to make installation decisions, but verifies that if we used
+`PRODUCT_HOST_PACKAGES`, it would trigger installation for all of the same host
+packages. This check ignores shared libraries, as those are not normally
+necessary in `PRODUCT_*PACKAGES`, and tended to be over-built (especially the
+32-bit variants).
+
+Future changes will switch installation decisions to `PRODUCT_HOST_PACKAGES`
+for host modules, error when there's a host-only module in `PRODUCT_PACKAGES`,
+and do some further cleanup where `LOCAL_REQUIRED_MODULES` are still merged
+between host and target modules with the same name.
+
+## `*.c.arm` / `*.cpp.arm` deprecation  {#file_arm}
+
+In Android.mk files, you used to be able to change LOCAL_ARM_MODE for each
+source file by appending `.arm` to the end of the filename in
+`LOCAL_SRC_FILES`.
+
+Soong does not support this uncommonly used behavior, instead expecting those
+files to be split out into a separate static library that chooses `arm` over
+`thumb` for the entire library. This must now also be done in Android.mk files.
+
+## Windows cross-compiles no longer supported in Android.mk
+
+Modules that build for Windows (our only `HOST_CROSS` OS currently) must now be
+defined in `Android.bp` files.
+
+## `LOCAL_MODULE_TAGS := eng debug` deprecation  {#LOCAL_MODULE_TAGS}
+
+`LOCAL_MODULE_TAGS` value `eng` and `debug` are being deprecated. They allowed
+modules to specify that they should always be installed on `-eng`, or `-eng`
+and `-userdebug` builds. This conflicted with the ability for products to
+specify which modules should be installed, effectively making it impossible to
+build a stripped down product configuration that did not include those modules.
+
+For the equivalent functionality, specify the modules in `PRODUCT_PACKAGES_ENG`
+or `PRODUCT_PACKAGES_DEBUG` in the appropriate product makefiles.
+
+Core android packages like `su` got added to the list in
+`build/make/target/product/base_system.mk`, but for device-specific modules
+there are often better base product makefiles to use instead.
+
+## `USER` deprecation  {#USER}
+
+`USER` will soon be `nobody` in many cases due to the addition of a sandbox
+around the Android build. Most of the time you shouldn't need to know the
+identity of the user running the build, but if you do, it's available in the
+make variable `BUILD_USERNAME` for now.
+
+Similarly, the `hostname` tool will also be returning a more consistent value
+of `android-build`. The real value is available as `BUILD_HOSTNAME`.
+
+## `BUILD_NUMBER` removal from Android.mk  {#BUILD_NUMBER}
+
+`BUILD_NUMBER` should not be used directly in Android.mk files, as it would
+trigger them to be re-read every time the `BUILD_NUMBER` changes (which it does
+on every build server build). If possible, just remove the use so that your
+builds are more reproducible. If you do need it, use `BUILD_NUMBER_FROM_FILE`:
+
+``` make
+$(LOCAL_BUILT_MODULE):
+	mytool --build_number $(BUILD_NUMBER_FROM_FILE) -o $@
+```
+
+That will expand out to a subshell that will read the current `BUILD_NUMBER`
+whenever it's run. It will not re-run your command if the build number has
+changed, so incremental builds will have the build number from the last time
+the particular output was rebuilt.
+
+## `DIST_DIR`, `dist_goal`, and `dist-for-goals`  {#dist}
+
+`DIST_DIR` and `dist_goal` are no longer available when reading Android.mk
+files (or other build tasks). Always use `dist-for-goals` instead, which takes
+a PHONY goal, and a list of files to copy to `$DIST_DIR`. Whenever `dist` is
+specified, and the goal would be built (either explicitly on the command line,
+or as a dependency of something on the command line), that file will be copied
+into `$DIST_DIR`. For example,
+
+``` make
+$(call dist-for-goals,foo,bar/baz)
+```
+
+will copy `bar/baz` into `$DIST_DIR/baz` when `m foo dist` is run.
+
+#### Renames during copy
+
+Instead of specifying just a file, a destination name can be specified,
+including subdirectories:
+
+``` make
+$(call dist-for-goals,foo,bar/baz:logs/foo.log)
+```
+
+will copy `bar/baz` into `$DIST_DIR/logs/foo.log` when `m foo dist` is run.
+
+## `.PHONY` rule enforcement  {#phony_targets}
+
+There are several new warnings/errors meant to ensure the proper use of
+`.PHONY` targets in order to improve the speed and reliability of incremental
+builds.
+
+`.PHONY`-marked targets are often used as shortcuts to provide "friendly" names
+for real files to be built, but any target marked with `.PHONY` is also always
+considered dirty, needing to be rebuilt every build. This isn't a problem for
+aliases or one-off user-requested operations, but if real builds steps depend
+on a `.PHONY` target, it can get quite expensive for what should be a tiny
+build.
+
+``` make
+...mk:42: warning: PHONY target "out/.../foo" looks like a real file (contains a "/")
+```
+
+Between this warning and the next, we're requiring that `.PHONY` targets do not
+have "/" in them, and real file targets do have a "/". This makes it more
+obvious when reading makefiles what is happening, and will help the build
+system differentiate these in the future too.
+
+``` make
+...mk:42: warning: writing to readonly directory: "kernel-modules"
+```
+
+This warning will show up for one of two reasons:
+
+1. The target isn't intended to be a real file, and should be marked with
+   `.PHONY`. This would be the case for this example.
+2. The target is a real file, but it's outside the output directories. All
+   outputs from the build system should be within the output directory,
+   otherwise `m clean` is unable to clean the build, and future builds may not
+   work properly.
+
+``` make
+...mk:42: warning: real file "out/.../foo" depends on PHONY target "buildbins"
+```
+
+If the first target isn't intended to be a real file, then it should be marked
+with `.PHONY`, which will satisfy this warning. This isn't the case for this
+example, as we require `.PHONY` targets not to have '/' in them.
+
+If the second (PHONY) target is a real file, it may unnecessarily be marked
+with `.PHONY`.
+
+### `.PHONY` and calling other build systems
+
+One common pattern (mostly outside AOSP) that we've seen hit these warning is
+when building with external build systems (firmware, bootloader, kernel, etc).
+Those are often marked as `.PHONY` because the Android build system doesn't
+have enough dependencies to know when to run the other build system again
+during an incremental build.
+
+We recommend to build these outside of Android, and deliver prebuilts into the
+Android tree instead of decreasing the speed and reliability of the incremental
+Android build.
+
+In cases where that's not desired, to preserve the speed of Android
+incrementals, over-specifying dependencies is likely a better option than
+marking it with `.PHONY`:
+
+``` make
+out/target/.../zImage: $(sort $(shell find -L $(KERNEL_SRCDIR)))
+	...
+```
+
+For reliability, many of these other build systems do not guarantee the same
+level of incremental build assurances as the Android Build is attempting to do
+-- without custom checks, Make doesn't rebuild objects when CFLAGS change, etc.
+In order to fix this, our recommendation is to do clean builds for each of
+these external build systems every time anything they rely on changes. For
+relatively smaller builds (like the kernel), this may be reasonable as long as
+you're not trying to actively debug the kernel.
+
+## `export` and `unexport` deprecation  {#export_keyword}
+
+The `export` and `unexport` keywords have been deprecated, and will throw
+warnings or errors depending on where they are used.
+
+Early in the make system, during product configuration and BoardConfig.mk
+reading: these will throw a warnings, and will be an error in the future.
+Device specific configuration should not be able to affect common core build
+steps -- we're looking at triggering build steps to be invalidated if the set
+of environment variables they can access changes. If device specific
+configuration is allowed to change those, switching devices with the same
+output directory could become significantly more expensive than it already can
+be.
+
+Later, during Android.mk files, and later tasks: these will throw errors, since
+it is increasingly likely that they are being used incorrectly, attempting to
+change the environment for a single build step, and instead setting it for
+hundreds of thousands.
+
+It is not recommended to just move the environment variable setting outside of
+the build (in vendorsetup.sh, or some other configuration script or wrapper).
+We expect to limit the environment variables that the build respects in the
+future, others will be cleared. (There will be methods to get custom variables
+into the build, just not to every build step)
+
+Instead, write the export commands into the rule command lines themselves:
+
+``` make
+$(intermediates)/generated_output.img:
+	rm -rf $@
+	export MY_ENV_A="$(MY_A)"; make ...
+```
+
+If you want to set many environment variables, and/or use them many times,
+write them out to a script and source the script:
+
+``` make
+envsh := $(intermediates)/env.sh
+$(envsh):
+	rm -rf $@
+	echo 'export MY_ENV_A="$(MY_A)"' >$@
+	echo 'export MY_ENV_B="$(MY_B)"' >>$@
+
+$(intermediates)/generated_output.img: PRIVATE_ENV := $(envsh)
+$(intermediates)/generated_output.img: $(envsh) a/b/c/package.sh
+	rm -rf $@
+	source $(PRIVATE_ENV); make ...
+	source $(PRIVATE_ENV); a/b/c/package.sh ...
+```
+
+## Implicit make rules are obsolete {#implicit_rules}
+
+Implicit rules look something like the following:
+
+``` make
+$(TARGET_OUT_SHARED_LIBRARIES)/%_vendor.so: $(TARGET_OUT_SHARED_LIBRARIES)/%.so
+	...
+
+%.o : %.foo
+	...
+```
+
+These can have wide ranging effects across unrelated modules, so they're now obsolete. Instead, use static pattern rules, which are similar, but explicitly match the specified outputs:
+
+``` make
+libs := $(foreach lib,libfoo libbar,$(TARGET_OUT_SHARED_LIBRARIES)/$(lib)_vendor.so)
+$(libs): %_vendor.so: %.so
+	...
+
+files := $(wildcard $(LOCAL_PATH)/*.foo)
+gen := $(patsubst $(LOCAL_PATH)/%.foo,$(intermediates)/%.o,$(files))
+$(gen): %.o : %.foo
+	...
+```
+
+## Removing '/' from Valid Module Names {#name_slash}
+
+The build system uses module names in path names in many places. Having an
+extra '/' or '../' being inserted can cause problems -- and not just build
+breaks, but stranger invalid behavior.
+
+In every case we've seen, the fix is relatively simple: move the directory into
+`LOCAL_MODULE_RELATIVE_PATH` (or `LOCAL_MODULE_PATH` if you're still using it).
+If this causes multiple modules to be named the same, use unique module names
+and `LOCAL_MODULE_STEM` to change the installed file name:
+
+``` make
+include $(CLEAR_VARS)
+LOCAL_MODULE := ver1/code.bin
+LOCAL_MODULE_PATH := $(TARGET_OUT_ETC)/firmware
+...
+include $(BUILD_PREBUILT)
+
+include $(CLEAR_VARS)
+LOCAL_MODULE := ver2/code.bin
+LOCAL_MODULE_PATH := $(TARGET_OUT_ETC)/firmware
+...
+include $(BUILD_PREBUILT)
+```
+
+Can be rewritten as:
+
+```
+include $(CLEAR_VARS)
+LOCAL_MODULE := ver1_code.bin
+LOCAL_MODULE_STEM := code.bin
+LOCAL_MODULE_PATH := $(TARGET_OUT_VENDOR)/firmware/ver1
+...
+include $(BUILD_PREBUILT)
+
+include $(CLEAR_VARS)
+LOCAL_MODULE := ver2_code.bin
+LOCAL_MODULE_STEM := code.bin
+LOCAL_MODULE_PATH := $(TARGET_OUT_VENDOR)/firmware/ver2
+...
+include $(BUILD_PREBUILT)
+```
+
+You just need to make sure that any other references (`PRODUCT_PACKAGES`,
+`LOCAL_REQUIRED_MODULES`, etc) are converted to the new names.
+
+## Valid Module Names {#name}
+
+We've adopted lexical requirements very similar to [Bazel's
+requirements](https://docs.bazel.build/versions/master/build-ref.html#name) for
+target names. Valid characters are `a-z`, `A-Z`, `0-9`, and the special
+characters `_.+-=,@~`. This currently applies to `LOCAL_PACKAGE_NAME`,
+`LOCAL_MODULE`, and `LOCAL_MODULE_SUFFIX`, and `LOCAL_MODULE_STEM*`.
+
+Many other characters already caused problems if you used them, so we don't
+expect this to have a large effect.
+
+## PATH Tools {#PATH_Tools}
+
+The build has started restricting the external host tools usable inside the
+build. This will help ensure that build results are reproducible across
+different machines, and catch mistakes before they become larger issues.
+
+To start with, this includes replacing the $PATH with our own directory of
+tools, mirroring that of the host PATH.  The only difference so far is the
+removal of the host GCC tools. Anything that is not explicitly in the
+configuration as allowed will continue functioning, but will generate a log
+message. This is expected to become more restrictive over time.
+
+The configuration is located in build/soong/ui/build/paths/config.go, and
+contains all the common tools in use in many builds. Anything not in that list
+will currently print a warning in the `$OUT_DIR/soong.log` file, including the
+command and arguments used, and the process tree in order to help locate the
+usage.
+
+In order to fix any issues brought up by these checks, the best way to fix them
+is to use tools checked into the tree -- either as prebuilts, or building them
+as host tools during the build.
+
+As a temporary measure, you can set `TEMPORARY_DISABLE_PATH_RESTRICTIONS=true`
+in your environment to temporarily turn off the error checks and allow any tool
+to be used (with logging). Beware that GCC didn't work well with the interposer
+used for logging, so this may not help in all cases.
+
 ## Deprecating / obsoleting envsetup.sh variables in Makefiles

-The "generic_mips64" product defines a MIPS64 based non-hardware-specific
-target without a kernel or bootloader.
-
-It can be used to build the entire user-level system, and
-will work with the emulator.
-
-It is not a product "base class"; no other products inherit
-from it or use it in any way.

 Generating the android_filesystem_config.h:
 
-To generate the android_filesystem_config.h file, one can choose from
-one of two methods. The first method, is to declare
-TARGET_ANDROID_FILESYSTEM_CONFIG_H in the device BoardConfig.mk file. This
-variable can only have one item in it, and it is used directly as the
-android_filesystem_config.h header when building
-fs_config_generate_$(TARGET_DEVICE) which is used to generate fs_config_files
-and fs_config_dirs target executable.
-
-The limitation with this, is that it can only be set once, thus if the device
-has a make hierarchy, then each device needs its own file, and cannot share
-from a common source or that common source needs to include everything from
-both devices.
-
-The other way is to set TARGET_FS_CONFIG_GEN, which can be a list of
-intermediate fs configuration files. It is a build error on any one
-these conditions:
- * Specify TARGET_FS_CONFIG_GEN and TARGET_ANDROID_FILESYSTEM_CONFIG_H
- * Specify TARGET_FS_CONFIG_GEN and provide
-   $(TARGET_DEVICE_DIR)/android_filesystem_config.h
+To generate the android_filesystem_config.h file, one can set
+TARGET_FS_CONFIG_GEN, which can be a list of intermediate fs configuration
+files.
 
 The parsing of the config file follows the Python ConfigParser specification,
 with the sections and fields as defined below. There are two types of sections,

+     care_map: a RangeSet containing which blocks (in the range [0,
+       total_blocks) we actually care about; i.e. which blocks contain data.
+
+     file_map: a dict that partitions the blocks contained in care_map into
+         smaller domains that are useful for doing diffs on. (Typically a domain
+         is a file, and the key in file_map is the pathname.)
+
+     clobbered_blocks: a RangeSet containing which blocks contain data but may
+         be altered by the FS. They need to be excluded when verifying the
+         partition integrity.
+
+     ReadRangeSet(): a function that takes a RangeSet and returns the data
+         contained in the image blocks of that RangeSet. The data is returned as
+         a list or tuple of strings; concatenating the elements together should
+         produce the requested data. Implementations are free to break up the
+         data into list/tuple elements in any way that is convenient.
+
+     RangeSha1(): a function that returns (as a hex string) the SHA-1 hash of
+         all the data in the specified range.
+
+     TotalSha1(): a function that returns (as a hex string) the SHA-1 hash of
+         all the data in the image (ie, all the blocks in the care_map minus
+         clobbered_blocks, or including the clobbered blocks if
+         include_clobbered_blocks is True).

+Usage: build_super_image input_file output_dir_or_file
+
+input_file: one of the following:
+  - directory containing extracted target files. It will load info from
+    META/misc_info.txt and build full super image / split images using source
+    images from IMAGES/.
+  - target files package. Same as above, but extracts the archive before
+    building super image.
+  - a dictionary file containing input arguments to build. Check
+    `dump_dynamic_partitions_info' for details.
+    In addition:
+    - "ab_update" needs to be true for A/B devices.
+    - If source images should be included in the output image (for super.img
+      and super split images), a list of "*_image" should be paths of each
+      source images.
+
+output_dir_or_file:
+    If a single super image is built (for super_empty.img, or super.img for
+    launch devices), this argument is the output file.
+    If a collection of split images are built (for retrofit devices), this
+    argument is the output directory.
