 # Soong
 
-Soong is the replacement for the old Android make-based build system.  It
-replaces Android.mk files with Android.bp files, which are JSON-like simple
-declarative descriptions of modules to build.
+Soong is one of the build systems used in Android. There are altogether three:
+* The legacy Make-based build system that is controlled by files called
+  `Android.mk`.
+* Soong, which is controlled by files called `Android.bp`.
+* The upcoming Bazel-based build system that is controlled by files called
+  `BUILD.bazel`.
+
+`Android.bp` file are JSON-like declarative descriptions of "modules" to build;
+a "module" is the basic unit of building that Soong understands, similarly to
+how "target" is the basic unit of building for Bazel (and Make, although the
+two kinds of "targets" are very different)
 
 See [Simple Build
 Configuration](https://source.android.com/compatibility/tests/development/blueprints)
 on source.android.com to read how Soong is configured for testing.
 
+### Contributing
+
+Code reviews are handled through the usual code review system of Android,
+available [here](https://android-review.googlesource.com/dashboard/self).
+
+For simple changes (fixing typos, obvious optimizations, etc.), sending a code
+review request is enough. For more substantial changes, file a bug in our
+[bug tracker](https://issuetracker.google.com/issues/new?component=381517) or
+or write us at android-building@googlegroups.com .
+
+For Googlers, see our [internal documentation](http://go/soong).

 ## Android.bp file format
 
 By design, Android.bp files are very simple.  There are no conditionals or
 control flow statements - any complexity is handled in build logic written in
 Go.  The syntax and semantics of Android.bp files are intentionally similar
-to [Bazel BUILD files](https://www.bazel.io/versions/master/docs/be/overview.html)
-when possible.
+to [Bazel BUILD files](https://bazel.build/concepts/build-files) when possible.

+Variables and properties are strongly typed. Variables are dynamically typed
+based on the first assignment, and properties are statically typed by the

 * Bool (`true` or `false`)
 * Integers (`int`)
 * Strings (`"string"`)
 * Lists of strings (`["string1", "string2"]`)
 * Maps (`{key1: "value1", key2: ["value2"]}`)

+Maps may contain values of any type, including nested maps. Lists and maps may
+have trailing commas after the last value.
 
 Strings can contain double quotes using `\"`, for example `"cat \"a b\""`.
 
 ### Operators
 
-Strings, lists of strings, and maps can be appended using the `+` operator.
-Integers can be summed up using the `+` operator. Appending a map produces the
-union of keys in both maps, appending the values of any keys that are present
-in both maps.
+The `+` operator:
+* Sums integers.
+* Concatenates strings and lists.
+* Produces the union of maps.

+Concatenating maps produces a map whose keys are the union of the given maps'
+keys, and whose mapped values are the union of the given maps' corresponding
+mapped values.

 ### Running Soong in a debugger
 
+Both the Android build driver (`soong_ui`) and Soong proper (`soong_build`) are
+Go applications and can be debugged with the help of the standard Go debugger
+called Delve. A client (e.g., IntelliJ IDEA) communicates with Delve via IP port
+that Delve listens to (the port number is passed to it on invocation).
+
+#### Debugging Android Build Driver ####
+To make `soong_ui` wait for a debugger connection, use the `SOONG_UI_DELVE`
+variable:
+
+```
+SOONG_UI_DELVE=5006 m nothing
+```
+
+#### Debugging Soong Proper ####
+
 To make `soong_build` wait for a debugger connection, install `dlv` and then
 start the build with `SOONG_DELVE=<listen addr>` in the environment.
 For example:
 ```bash
-SOONG_DELVE=:5006 m nothing
+SOONG_DELVE=5006 m nothing
 ```
-
-To make `soong_ui` wait for a debugger connection, use the `SOONG_UI_DELVE`
-variable:
-
+Android build driver invokes `soong_build` multiple times, and by default each
+invocation is run in the debugger. Setting `SOONG_DELVE_STEPS` controls which
+invocations are run in the debugger, e.g., running
+```bash
+SOONG_DELVE=2345 SOONG_DELVE_STEPS='build,modulegraph' m
 ```
-SOONG_UI_DELVE=:5006 m nothing
-```
+results in only `build` (main build step) and `modulegraph` being run in the debugger.
+The allowed step names are `api_bp2build`, `bp2build_files`, `bp2build_workspace`,
+`build`, `modulegraph`, `queryview`, `soong_docs`.

-setting or unsetting `SOONG_DELVE` causes a recompilation of `soong_build`. This
+Note setting or unsetting `SOONG_DELVE` causes a recompilation of `soong_build`. This

 To connect to the process using IntelliJ:
 
 * Run -> Edit Configurations...
 * Choose "Go Remote" on the left
 * Click on the "+" buttion on the top-left

+* Give it a nice _name_ and set "Host" to `localhost` and "Port" to the port in the

+* Set the breakpoints where you want application to stop
+* Run the build from the command line
+* In IntelliJ, click Run -> Debug _name_
+* Observe _Connecting..._ message in the debugger pane. It changes to
+  _Connected_ once the communication with the debugger has been established; the
+  terminal window where the build started will display
+  `API server listening at ...` message
 
-Debugging works far worse than debugging Java, but is sometimes useful.
 
 Sometimes the `dlv` process hangs on connection. A symptom of this is `dlv`
 spinning a core or two. In that case, `kill -9` `dlv` and try again.

+// Transition mutators implement a top-down mechanism where a module tells its
+// direct dependencies what variation they should be built in but the dependency
+// has the final say.
+//
+// When implementing a transition mutator, one needs to implement four methods:
+//   - Split() that tells what variations a module has by itself
+//   - OutgoingTransition() where a module tells what it wants from its
+//     dependency
+//   - IncomingTransition() where a module has the final say about its own
+//     variation
+//   - Mutate() that changes the state of a module depending on its variation
+//
+// That the effective variation of module B when depended on by module A is the
+// composition the outgoing transition of module A and the incoming transition
+// of module B.
+//
+// the outgoing transition should not take the properties of the dependency into
+// account, only those of the module that depends on it. For this reason, the
+// dependency is not even passed into it as an argument. Likewise, the incoming
+// transition should not take the properties of the depending module into
+// account and is thus not informed about it. This makes for a nice
+// decomposition of the decision logic.
+//
+// A given transition mutator only affects its own variation; other variations
+// stay unchanged along the dependency edges.
+//
+// Soong makes sure that all modules are created in the desired variations and
+// that dependency edges are set up correctly. This ensures that "missing
+// variation" errors do not happen and allows for more flexible changes in the
+// value of the variation among dependency edges (as oppposed to bottom-up
+// mutators where if module A in variation X depends on module B and module B
+// has that variation X, A must depend on variation X of B)
+//
+// The limited power of the context objects passed to individual mutators
+// methods also makes it more difficult to shoot oneself in the foot. Complete
+// safety is not guaranteed because no one prevents individual transition
+// mutators from mutating modules in illegal ways and for e.g. Split() or
+// Mutate() to run their own visitations of the transitive dependency of the
+// module and both of these are bad ideas, but it's better than no guardrails at
+// all.
+//
+// This model is pretty close to Bazel's configuration transitions. The mapping
+// between concepts in Soong and Bazel is as follows:
+//   - Module == configured target
+//   - Variant == configuration
+//   - Variation name == configuration flag
+//   - Variation == configuration flag value
+//   - Outgoing transition == attribute transition
+//   - Incoming transition == rule transition
+//
+// The Split() method does not have a Bazel equivalent and Bazel split
+// transitions do not have a Soong equivalent.
+//
+// Mutate() does not make sense in Bazel due to the different models of the
+// two systems: when creating new variations, Soong clones the old module and
+// thus some way is needed to change it state whereas Bazel creates each
+// configuration of a given configured target anew.

-// As sysprop_library has to support both Java and C++, sysprop_library internally

-//
-//     sysprop_library {
-//         name: "foo",

-//
-// will internally generate with prefix "lib"

-//
-// When a cc module links against "foo", build system will redirect the
-// dependency to "libfoo". To do that, SyspropMutator gathers all sysprop_library,
-// records their cc implementation library names to a map. The map will be used in

-APIs exposed by an APEX to the platform or another APEX.
+Indicates that the symbol is exposed by the platform for an apex. Whereas `apex`
+should be used for APIs exposed by an APEX to the platform or another APEX.
+
+May be used in combination with `llndk` if the symbol is exposed to both APEX
+and the LL-NDK.
+
+Since a single library can be installed ether in platform or an apex, but not
+both, a single map.txt file should not contain _both_ # apex and # systemapi symbols.
+
+The granularity between # apex and # systemapi exists to help the API review
+process (b/191371676). These two symbols have very similar lifetime "in
+practice". A #systemapi symbol can be dropped from the next release if we are
+confident that no one is using it. Similarily, #apex can be dropped if we are
+sure that the old platform which used the symbol has reached EOL and thus is no
+longer accepting new APEX updates. Unlike the APIs for apps where we have zero
+control over how APIs are used, we are in a much more controllable environment
+when talking about #systemapi and #apex symbols. So, we have some flexibility
+here when determining the lifetime of a symbol.

 // Environment variables that affect the generated snapshot
 // ========================================================
 //
-// SOONG_SDK_SNAPSHOT_PREFER
-//     By default every unversioned module in the generated snapshot has prefer: false. Building it
-//     with SOONG_SDK_SNAPSHOT_PREFER=true will force them to use prefer: true.
-//
-// SOONG_SDK_SNAPSHOT_USE_SOURCE_CONFIG_VAR
-//     If set this specifies the Soong config var that can be used to control whether the prebuilt
-//     modules from the generated snapshot or the original source modules. Values must be a colon
-//     separated pair of strings, the first of which is the Soong config namespace, and the second
-//     is the name of the variable within that namespace.
-//
-//     The config namespace and var name are used to set the `use_source_config_var` property. That
-//     in turn will cause the generated prebuilts to use the soong config variable to select whether
-//     source or the prebuilt is used.
-//     e.g. If an sdk snapshot is built using:
-//       m SOONG_SDK_SNAPSHOT_USE_SOURCE_CONFIG_VAR=acme:build_from_source sdkextensions-sdk
-//     Then the resulting snapshot will include:
-//       use_source_config_var: {
-//         config_namespace: "acme",
-//         var_name: "build_from_source",
-//       }
-//
-//     Assuming that the config variable is defined in .mk using something like:
-//       $(call add_soong_config_namespace,acme)
-//       $(call add_soong_config_var_value,acme,build_from_source,true)
-//
-//     Then when the snapshot is unpacked in the repository it will have the following behavior:
-//       m droid - will use the sdkextensions-sdk prebuilts if present. Otherwise, it will use the
-//           sources.
-//       m SOONG_CONFIG_acme_build_from_source=true droid - will use the sdkextensions-sdk
-//            sources, if present. Otherwise, it will use the prebuilts.
-//
-//     This is a temporary mechanism to control the prefer flags and will be removed once a more
-//     maintainable solution has been implemented.
-//     TODO(b/174997203): Remove when no longer necessary.
-//
-// SOONG_SDK_SNAPSHOT_VERSION
-//     This provides control over the version of the generated snapshot.
-//
-//     SOONG_SDK_SNAPSHOT_VERSION=current will generate unversioned and versioned prebuilts and a
-//     versioned snapshot module. This is the default behavior. The zip file containing the
-//     generated snapshot will be <sdk-name>-current.zip.
-//
-//     SOONG_SDK_SNAPSHOT_VERSION=unversioned will generate unversioned prebuilts only and the zip
-//     file containing the generated snapshot will be <sdk-name>.zip.
-//
-//     SOONG_SDK_SNAPSHOT_VERSION=<number> will generate versioned prebuilts and a versioned
-//     snapshot module only. The zip file containing the generated snapshot will be
-//     <sdk-name>-<number>.zip.
-//
 // SOONG_SDK_SNAPSHOT_TARGET_BUILD_RELEASE
 //     This allows the target build release (i.e. the release version of the build within which
 //     the snapshot will be used) of the snapshot to be specified. If unspecified then it defaults
