 # Build System Changes for Android.mk Writers
 
+## COPY_HEADERS usage now produces warnings {#copy_headers}
+
+We've considered `BUILD_COPY_HEADERS`/`LOCAL_COPY_HEADERS` to be deprecated for
+a long time, and the places where it's been able to be used have shrinked over
+the last several releases. Equivalent functionality is not available in Soong.
+
+See the [build/soong/docs/best_practices.md#headers] for more information about
+how best to handle headers in Android.
+
+## `m4` is not available on `$PATH`
+
+There is a prebuilt of it available in prebuilts/build-tools, and a make
+variable `M4` that contains the path.
+
+Beyond the direct usage, whenever you use bison or flex directly, they call m4
+behind the scene, so you must set the M4 environment variable (and depend upon
+it for incremental build correctness):
+
+```
+$(intermediates)/foo.c: .KATI_IMPLICIT_OUTPUTS := $(intermediates)/foo.h
+$(intermediates)/foo.c: $(LOCAL_PATH)/foo.y $(M4) $(BISON) $(BISON_DATA)
+	M4=$(M4) $(BISON) ...
+```
+
+## Rules executed within limited environment
+
+With `ALLOW_NINJA_ENV=false` (soon to be the default), ninja, and all the
+rules/actions executed within it will only have access to a limited number of
+environment variables. Ninja does not track when environment variables change
+in order to trigger rebuilds, so changing behavior based on arbitrary variables
+is not safe with incremental builds.
+
+Kati and Soong can safely use environment variables, so the expectation is that
+you'd embed any environment variables that you need to use within the command
+line generated by those tools. See the [export section](#export_keyword) below
+for examples.
+
+For a temporary workaround, you can set `ALLOW_NINJA_ENV=true` in your
+environment to restore the previous behavior, or set
+`BUILD_BROKEN_NINJA_USES_ENV_VAR := <var> <var2> ...` in your `BoardConfig.mk`
+to allow specific variables to be passed through until you've fixed the rules.
+
+## LOCAL_C_INCLUDES outside the source/output trees are an error {#BUILD_BROKEN_OUTSIDE_INCLUDE_DIRS}
+
+Include directories are expected to be within the source tree (or in the output
+directory, generated during the build). This has been checked in some form
+since Oreo, but now has better checks.
+
+There's now a `BUILD_BROKEN_OUTSIDE_INCLUDE_DIRS` variable, that when set, will
+turn these errors into warnings temporarily. I don't expect this to last more
+than a release, since they're fairly easy to clean up.
+
+Neither of these cases are supported by Soong, and will produce errors when
+converting your module.
+
+### Absolute paths
+
+This has been checked since Oreo. The common reason to hit this is because a
+makefile is calculating a path, and ran abspath/realpath/etc. This is a problem
+because it makes your build non-reproducible. It's very unlikely that your
+source path is the same on every machine.
+
+### Using `../` to leave the source/output directories
+
+This is the new check that has been added. In every case I've found, this has
+been a mistake in the Android.mk -- assuming that `LOCAL_C_INCLUDES` (which is
+relative to the top of the source tree) acts like `LOCAL_SRC_FILES` (which is
+relative to `LOCAL_PATH`).
+
+Since this usually isn't a valid path, you can almost always just remove the
+offending line.
+
+
+## `BOARD_HAL_STATIC_LIBRARIES` and `LOCAL_HAL_STATIC_LIBRARIES` are obsolete {#BOARD_HAL_STATIC_LIBRARIES}
+
+Define proper HIDL / Stable AIDL HAL instead.
+
+* For libhealthd, use health HAL. See instructions for implementing
+  health HAL:
+
+  * [hardware/interfaces/health/2.1/README.md] for health 2.1 HAL (recommended)
+  * [hardware/interfaces/health/1.0/README.md] for health 1.0 HAL
+
+* For libdumpstate, use at least Dumpstate HAL 1.0.
+
 ## PRODUCT_STATIC_BOOT_CONTROL_HAL is obsolete {#PRODUCT_STATIC_BOOT_CONTROL_HAL}
 
 `PRODUCT_STATIC_BOOT_CONTROL_HAL` was the workaround to allow sideloading with

-Use option --byproject to output tables grouped by source file projects.
-Use option --gencsv to output warning counts in CSV format.
+This script is used by Android continuous build bots for all branches.
+Old frozen branches will continue to use the old warn.py, and active
