+# Run Caliper benchmark tests using vogar on a rooted device
+
+- It uses the [Caliper library](https://github.com/google/caliper) developed by Google.
+- Vogar source codes can be found at `external/vogar`.
+
+1. Preparation
+
+```shell
+# vogar requires com.android.art.testing
+m vogar com.android.art.testing
+# remount if you haven't done so.
+adb root && adb remount && adb reboot && adb wait-for-device root
+cd libcore/benchmarks/src
+```
+
+Extra options to reduce noise:
+```shell
+adb shell stop # to kill frameworks and zygote
+```
+
+2. Run an individual test
+
+```shell
+vogar --benchmark benchmarks/regression/ScannerBenchmark.java
+```
+
+The source code of the tests can be found at `src/benchmarks/`
+
+# Run Jetpack benchmark tests
+Docs about Jetpack Benchmark can be found at
+[https://developer.android.com/studio/profile/benchmarking-overview]()
+
+1. Preparation
+
+To lock CPU clocks on a rooted device,
+run the script provided at [https://developer.android.com/studio/profile/run-benchmarks-in-ci#clock-locking]().
+
+2. Run an individual test
+```shell
+atest LibcoreBenchmarkTests:libcore.benchmark.FormatterTest#stringFormatNumber_allLocales
+```
+
+The source code of the tests can be found at `src_androidx/libcore/benchmark/`
+
+## Outdated documentation / Not working
+
+###VM Options
+
+
+The VM's configuration will have a substantial impact on performance.
+Use Caliper's -J<name> <value 1>,<value 2>,<value 3> syntax to compare different VM options. For example:
+```shell
+vogar --benchmark ~/svn/dalvik/benchmarks/regression/CrespoFileIoRegressionBenchmark.java \
+-- -Jgc -Xgc:noconcurrent,-Xgc:concurrent -Jint -Xint:fast,-Xint:jit,-Xint:portable

+ * Indicates that an API should never be compiled.

+ * NeverCompile can be used to annotate methods that should not be compiled and included in .odex
+ * files. Methods that are not called frequently, are never speed-critical, or are only used for
+ * debugging do not necessarily need to run quickly. Applying this annotation to prevent these
+ * methods from being compiled will return some size improvements in the .odex file that they would
+ * otherwise be included in.
+ * </p>
+ *
+ * <p>
+ * This annotation will have no effect when applied to native methods, as JNI stubs will still be
+ * compiled. In addition, it will not stop overriding methods from being compiled, so applying this
+ * annotation to abstract methods will not do anything.
+ * </p>
+ *
+ * <p>
+ * The <code>dumpPackageLPr</code> method in com.android.server.pm can be used as a concrete
+ * example. This is a debug method used to dump all of the information about a device's installed
+ * packages. When it is compiled, it is included in services.odex. Annotating this method with
+ * NeverCompile can be seen to reduce the size of services.odex by roughly 28KB.

+ * action in one library will only minimally affect cleaning actions in another.
+ *
+ * However, this comes at the cost of introducing one Cleaner thread per library that uses
+ * Cleaners. This could introduce dozens of additional threads per process, which is often
+ * not an acceptable cost, especially on memory-limited devices.
+ *
+ * SystemCleaner instead provides access to a shared Cleaner, shared across the entire process.
+ * It is greatly preferred when all cleaning actions registered by a client are known to
+ * complete quickly, without explicit I/O, interprocess communication, or network access.
+ * Registering a non-terminating or excessively slow cleaning action with the shared cleaner
+ * may cause the process to perform very badly, hang, or be killed.
+ *
+ * Only for developers of the Android platform itself: As with all Cleaners, use of SystemCleaner

+/**
+ * In upstream, this class (StringUTF16) contains implementations of various APIs and their helper
+ * methods for uncompressed strings. Libcore makes use of it to implement APIs for both compressed
+ * and uncompressed strings.
+ *
+ * Upstream implementation also has StringLatin1 class which contains same implementations for
+ * compressed strings (and this class is for uncompressed). In our case we use only StringUTF16
+ * (and StringLatin1 is intentionally not imported) as string characters are managed by ART and
+ * everything is implemented in terms of {@link String#charAt(int)} an other primitives which do not
+ * have direct access to underlying character array. From those two, if we choose to implement
+ * everything in those primitives, StringUTF16 has less difference with upstream, so it is chosen
+ * here.

+ * Constructs a method handle representing a loop with several loop variables that are updated and checked upon each
+ * iteration. Upon termination of the loop due to one of the predicates, a corresponding finalizer is run and
+ * delivers the loop's result, which is the return value of the resulting handle.
+ * <p>
+ * Intuitively, every loop is formed by one or more "clauses", each specifying a local <em>iteration variable</em> and/or a loop
+ * exit. Each iteration of the loop executes each clause in order. A clause can optionally update its iteration
+ * variable; it can also optionally perform a test and conditional loop exit. In order to express this logic in
+ * terms of method handles, each clause will specify up to four independent actions:<ul>
+ * <li><em>init:</em> Before the loop executes, the initialization of an iteration variable {@code v} of type {@code V}.
+ * <li><em>step:</em> When a clause executes, an update step for the iteration variable {@code v}.
+ * <li><em>pred:</em> When a clause executes, a predicate execution to test for loop exit.
+ * <li><em>fini:</em> If a clause causes a loop exit, a finalizer execution to compute the loop's return value.
+ * </ul>
+ * The full sequence of all iteration variable types, in clause order, will be notated as {@code (V...)}.
+ * The values themselves will be {@code (v...)}. When we speak of "parameter lists", we will usually
+ * be referring to types, but in some contexts (describing execution) the lists will be of actual values.
+ * <p>
+ * Some of these clause parts may be omitted according to certain rules, and useful default behavior is provided in
+ * this case. See below for a detailed description.
+ * <p>
+ * <em>Parameters optional everywhere:</em>
+ * Each clause function is allowed but not required to accept a parameter for each iteration variable {@code v}.
+ * As an exception, the init functions cannot take any {@code v} parameters,
+ * because those values are not yet computed when the init functions are executed.
+ * Any clause function may neglect to take any trailing subsequence of parameters it is entitled to take.
+ * In fact, any clause function may take no arguments at all.
+ * <p>
+ * <em>Loop parameters:</em>
+ * A clause function may take all the iteration variable values it is entitled to, in which case
+ * it may also take more trailing parameters. Such extra values are called <em>loop parameters</em>,
+ * with their types and values notated as {@code (A...)} and {@code (a...)}.
+ * These become the parameters of the resulting loop handle, to be supplied whenever the loop is executed.
+ * (Since init functions do not accept iteration variables {@code v}, any parameter to an
+ * init function is automatically a loop parameter {@code a}.)
+ * As with iteration variables, clause functions are allowed but not required to accept loop parameters.
+ * These loop parameters act as loop-invariant values visible across the whole loop.
+ * <p>
+ * <em>Parameters visible everywhere:</em>
+ * Each non-init clause function is permitted to observe the entire loop state, because it can be passed the full
+ * list {@code (v... a...)} of current iteration variable values and incoming loop parameters.
+ * The init functions can observe initial pre-loop state, in the form {@code (a...)}.
+ * Most clause functions will not need all of this information, but they will be formally connected to it
+ * as if by {@link #dropArguments}.
+ * <a id="astar"></a>
+ * More specifically, we shall use the notation {@code (V*)} to express an arbitrary prefix of a full
+ * sequence {@code (V...)} (and likewise for {@code (v*)}, {@code (A*)}, {@code (a*)}).
+ * In that notation, the general form of an init function parameter list
+ * is {@code (A*)}, and the general form of a non-init function parameter list is {@code (V*)} or {@code (V... A*)}.
+ * <p>
+ * <em>Checking clause structure:</em>
+ * Given a set of clauses, there is a number of checks and adjustments performed to connect all the parts of the
+ * loop. They are spelled out in detail in the steps below. In these steps, every occurrence of the word "must"
+ * corresponds to a place where {@link IllegalArgumentException} will be thrown if the required constraint is not
+ * met by the inputs to the loop combinator.
+ * <p>
+ * <em>Effectively identical sequences:</em>
+ * <a id="effid"></a>
+ * A parameter list {@code A} is defined to be <em>effectively identical</em> to another parameter list {@code B}
+ * if {@code A} and {@code B} are identical, or if {@code A} is shorter and is identical with a proper prefix of {@code B}.
+ * When speaking of an unordered set of parameter lists, we say they the set is "effectively identical"
+ * as a whole if the set contains a longest list, and all members of the set are effectively identical to
+ * that longest list.
+ * For example, any set of type sequences of the form {@code (V*)} is effectively identical,
+ * and the same is true if more sequences of the form {@code (V... A*)} are added.
+ * <p>
+ * <em>Step 0: Determine clause structure.</em><ol type="a">
+ * <li>The clause array (of type {@code MethodHandle[][]}) must be non-{@code null} and contain at least one element.
+ * <li>The clause array may not contain {@code null}s or sub-arrays longer than four elements.
+ * <li>Clauses shorter than four elements are treated as if they were padded by {@code null} elements to length
+ * four. Padding takes place by appending elements to the array.
+ * <li>Clauses with all {@code null}s are disregarded.
+ * <li>Each clause is treated as a four-tuple of functions, called "init", "step", "pred", and "fini".
+ * </ol>
+ * <p>
+ * <em>Step 1A: Determine iteration variable types {@code (V...)}.</em><ol type="a">
+ * <li>The iteration variable type for each clause is determined using the clause's init and step return types.
+ * <li>If both functions are omitted, there is no iteration variable for the corresponding clause ({@code void} is
+ * used as the type to indicate that). If one of them is omitted, the other's return type defines the clause's
+ * iteration variable type. If both are given, the common return type (they must be identical) defines the clause's
+ * iteration variable type.
+ * <li>Form the list of return types (in clause order), omitting all occurrences of {@code void}.
+ * <li>This list of types is called the "iteration variable types" ({@code (V...)}).
+ * </ol>
+ * <p>
+ * <em>Step 1B: Determine loop parameters {@code (A...)}.</em><ul>
+ * <li>Examine and collect init function parameter lists (which are of the form {@code (A*)}).
+ * <li>Examine and collect the suffixes of the step, pred, and fini parameter lists, after removing the iteration variable types.
+ * (They must have the form {@code (V... A*)}; collect the {@code (A*)} parts only.)
+ * <li>Do not collect suffixes from step, pred, and fini parameter lists that do not begin with all the iteration variable types.
+ * (These types will be checked in step 2, along with all the clause function types.)
+ * <li>Omitted clause functions are ignored. (Equivalently, they are deemed to have empty parameter lists.)
+ * <li>All of the collected parameter lists must be effectively identical.
+ * <li>The longest parameter list (which is necessarily unique) is called the "external parameter list" ({@code (A...)}).
+ * <li>If there is no such parameter list, the external parameter list is taken to be the empty sequence.
+ * <li>The combined list consisting of iteration variable types followed by the external parameter types is called
+ * the "internal parameter list".
+ * </ul>
+ * <p>
+ * <em>Step 1C: Determine loop return type.</em><ol type="a">
+ * <li>Examine fini function return types, disregarding omitted fini functions.
+ * <li>If there are no fini functions, the loop return type is {@code void}.
+ * <li>Otherwise, the common return type {@code R} of the fini functions (their return types must be identical) defines the loop return
+ * type.
+ * </ol>
+ * <p>
+ * <em>Step 1D: Check other types.</em><ol type="a">
+ * <li>There must be at least one non-omitted pred function.
+ * <li>Every non-omitted pred function must have a {@code boolean} return type.
+ * </ol>
+ * <p>
+ * <em>Step 2: Determine parameter lists.</em><ol type="a">
+ * <li>The parameter list for the resulting loop handle will be the external parameter list {@code (A...)}.
+ * <li>The parameter list for init functions will be adjusted to the external parameter list.
+ * (Note that their parameter lists are already effectively identical to this list.)
+ * <li>The parameter list for every non-omitted, non-init (step, pred, and fini) function must be
+ * effectively identical to the internal parameter list {@code (V... A...)}.
+ * </ol>
+ * <p>
+ * <em>Step 3: Fill in omitted functions.</em><ol type="a">
+ * <li>If an init function is omitted, use a {@linkplain #empty default value} for the clause's iteration variable
+ * type.
+ * <li>If a step function is omitted, use an {@linkplain #identity identity function} of the clause's iteration
+ * variable type; insert dropped argument parameters before the identity function parameter for the non-{@code void}
+ * iteration variables of preceding clauses. (This will turn the loop variable into a local loop invariant.)
+ * <li>If a pred function is omitted, use a constant {@code true} function. (This will keep the loop going, as far
+ * as this clause is concerned. Note that in such cases the corresponding fini function is unreachable.)
+ * <li>If a fini function is omitted, use a {@linkplain #empty default value} for the
+ * loop return type.

+ * <p>
+ * <em>Final observations.</em><ol type="a">
+ * <li>After these steps, all clauses have been adjusted by supplying omitted functions and arguments.
+ * <li>All init functions have a common parameter type list {@code (A...)}, which the final loop handle will also have.
+ * <li>All fini functions have a common return type {@code R}, which the final loop handle will also have.
+ * <li>All non-init functions have a common parameter type list {@code (V... A...)}, of
+ * (non-{@code void}) iteration variables {@code V} followed by loop parameters.
+ * <li>Each pair of init and step functions agrees in their return type {@code V}.
+ * <li>Each non-init function will be able to observe the current values {@code (v...)} of all iteration variables.
+ * <li>Every function will be able to observe the incoming values {@code (a...)} of all loop parameters.
+ * </ol>
+ * <p>
+ * <em>Example.</em> As a consequence of step 1A above, the {@code loop} combinator has the following property:
+ * <ul>
+ * <li>Given {@code N} clauses {@code Cn = {null, Sn, Pn}} with {@code n = 1..N}.
+ * <li>Suppose predicate handles {@code Pn} are either {@code null} or have no parameters.
+ * (Only one {@code Pn} has to be non-{@code null}.)
+ * <li>Suppose step handles {@code Sn} have signatures {@code (B1..BX)Rn}, for some constant {@code X>=N}.
+ * <li>Suppose {@code Q} is the count of non-void types {@code Rn}, and {@code (V1...VQ)} is the sequence of those types.
+ * <li>It must be that {@code Vn == Bn} for {@code n = 1..min(X,Q)}.
+ * <li>The parameter types {@code Vn} will be interpreted as loop-local state elements {@code (V...)}.
+ * <li>Any remaining types {@code BQ+1..BX} (if {@code Q<X}) will determine
+ * the resulting loop handle's parameter types {@code (A...)}.
+ * </ul>
+ * In this example, the loop handle parameters {@code (A...)} were derived from the step functions,
+ * which is natural if most of the loop computation happens in the steps. For some loops,
+ * the burden of computation might be heaviest in the pred functions, and so the pred functions
+ * might need to accept the loop parameter values. For loops with complex exit logic, the fini
+ * functions might need to accept loop parameters, and likewise for loops with complex entry logic,
+ * where the init functions will need the extra parameters. For such reasons, the rules for
+ * determining these parameters are as symmetric as possible, across all clause parts.
+ * In general, the loop parameters function as common invariant values across the whole
+ * loop, while the iteration variables function as common variant values, or (if there is
+ * no step function) as internal loop invariant temporaries.
+ * <p>
+ * <em>Loop execution.</em><ol type="a">
+ * <li>When the loop is called, the loop input values are saved in locals, to be passed to
+ * every clause function. These locals are loop invariant.
+ * <li>Each init function is executed in clause order (passing the external arguments {@code (a...)})
+ * and the non-{@code void} values are saved (as the iteration variables {@code (v...)}) into locals.
+ * These locals will be loop varying (unless their steps behave as identity functions, as noted above).
+ * <li>All function executions (except init functions) will be passed the internal parameter list, consisting of
+ * the non-{@code void} iteration values {@code (v...)} (in clause order) and then the loop inputs {@code (a...)}
+ * (in argument order).
+ * <li>The step and pred functions are then executed, in clause order (step before pred), until a pred function
+ * returns {@code false}.
+ * <li>The non-{@code void} result from a step function call is used to update the corresponding value in the
+ * sequence {@code (v...)} of loop variables.
+ * The updated value is immediately visible to all subsequent function calls.
+ * <li>If a pred function returns {@code false}, the corresponding fini function is called, and the resulting value
+ * (of type {@code R}) is returned from the loop as a whole.
+ * <li>If all the pred functions always return true, no fini function is ever invoked, and the loop cannot exit
+ * except by throwing an exception.
+ * </ol>
+ * <p>
+ * <em>Usage tips.</em>
+ * <ul>
+ * <li>Although each step function will receive the current values of <em>all</em> the loop variables,
+ * sometimes a step function only needs to observe the current value of its own variable.
+ * In that case, the step function may need to explicitly {@linkplain #dropArguments drop all preceding loop variables}.
+ * This will require mentioning their types, in an expression like {@code dropArguments(step, 0, V0.class, ...)}.
+ * <li>Loop variables are not required to vary; they can be loop invariant. A clause can create
+ * a loop invariant by a suitable init function with no step, pred, or fini function. This may be
+ * useful to "wire" an incoming loop argument into the step or pred function of an adjacent loop variable.
+ * <li>If some of the clause functions are virtual methods on an instance, the instance
+ * itself can be conveniently placed in an initial invariant loop "variable", using an initial clause
+ * like {@code new MethodHandle[]{identity(ObjType.class)}}. In that case, the instance reference
+ * will be the first iteration variable value, and it will be easy to use virtual
+ * methods as clause parts, since all of them will take a leading instance reference matching that value.
+ * </ul>
+ * <p>
+ * Here is pseudocode for the resulting loop handle. As above, {@code V} and {@code v} represent the types
+ * and values of loop variables; {@code A} and {@code a} represent arguments passed to the whole loop;
+ * and {@code R} is the common result type of all finalizers as well as of the resulting loop.
+ * <blockquote><pre>{@code
+ * V... init...(A...);
+ * boolean pred...(V..., A...);
+ * V... step...(V..., A...);
+ * R fini...(V..., A...);
+ * R loop(A... a) {
+ * V... v... = init...(a...);
+ * for (;;) {
+ * for ((v, p, s, f) in (v..., pred..., step..., fini...)) {
+ * v = s(v..., a...);
+ * if (!p(v..., a...)) {
+ * return f(v..., a...);
+ * }
+ * }
+ * }
+ * }
+ * }</pre></blockquote>
+ * Note that the parameter type lists {@code (V...)} and {@code (A...)} have been expanded
+ * to their full length, even though individual clause functions may neglect to take them all.
+ * As noted above, missing parameters are filled in as if by {@link #dropArgumentsToMatch(MethodHandle, int, List, int)}.
+ *
+ * @apiNote Example:

+ * and we will write {@code (V T A...)V} with the understanding that a {@code void} type {@code V}
+ * is quietly dropped from the parameter list, leaving {@code (T A...)V}.)
+ * <li>The parameter list {@code (V T A...)} of the body contributes to a list
+ * of types called the <em>internal parameter list</em>.
+ * It will constrain the parameter lists of the other loop parts.
+ * <li>As a special case, if the body contributes only {@code V} and {@code T} types,
+ * with no additional {@code A} types, then the internal parameter list is extended by
+ * the argument types {@code A...} of the {@code iterator} handle; if it is {@code null} the
+ * single type {@code Iterable} is added and constitutes the {@code A...} list.
+ * <li>If the iteration variable types {@code (V T)} are dropped from the internal parameter list, the resulting shorter
+ * list {@code (A...)} is called the <em>external parameter list</em>.
+ * <li>The body return type {@code V}, if non-{@code void}, determines the type of an
+ * additional state variable of the loop.
+ * The body must both accept a leading parameter and return a value of this type {@code V}.
+ * <li>If {@code init} is non-{@code null}, it must have return type {@code V}.
+ * Its parameter list (of some <a href="MethodHandles.html#astar">form {@code (A*)}</a>) must be
+ * <a href="MethodHandles.html#effid">effectively identical</a>
+ * to the external parameter list {@code (A...)}.
+ * <li>If {@code init} is {@code null}, the loop variable will be initialized to its
+ * {@linkplain #empty default value}.
+ * <li>If the {@code iterator} handle is non-{@code null}, it must have the return
+ * type {@code java.util.Iterator} or a subtype thereof.
+ * The iterator it produces when the loop is executed will be assumed
+ * to yield values which can be converted to type {@code T}.
+ * <li>The parameter list of an {@code iterator} that is non-{@code null} (of some form {@code (A*)}) must be
+ * effectively identical to the external parameter list {@code (A...)}.
+ * <li>If {@code iterator} is {@code null} it defaults to a method handle which behaves
+ * like {@link java.lang.Iterable#iterator()}. In that case, the internal parameter list
+ * {@code (V T A...)} must have at least one {@code A} type, and the default iterator
+ * handle parameter is adjusted to accept the leading {@code A} type, as if by
+ * the {@link MethodHandle#asType asType} conversion method.
+ * The leading {@code A} type must be {@code Iterable} or a subtype thereof.
+ * This conversion step, done at loop construction time, must not throw a {@code WrongMethodTypeException}.
+ * </ul>
+ * <p>
+ * The type {@code T} may be either a primitive or reference.
+ * Since type {@code Iterator<T>} is erased in the method handle representation to the raw type {@code Iterator},
+ * the {@code iteratedLoop} combinator adjusts the leading argument type for {@code body} to {@code Object}
+ * as if by the {@link MethodHandle#asType asType} conversion method.
+ * Therefore, if an iterator of the wrong type appears as the loop is executed, runtime exceptions may occur
+ * as the result of dynamic conversions performed by {@link MethodHandle#asType(MethodType)}.
+ * <p>
+ * The resulting loop handle's result type and parameter signature are determined as follows:<ul>
+ * <li>The loop handle's result type is the result type {@code V} of the body.
+ * <li>The loop handle's parameter types are the types {@code (A...)},
+ * from the external parameter list.
+ * </ul>
+ * <p>
+ * Here is pseudocode for the resulting loop handle. In the code, {@code V}/{@code v} represent the type / value of
+ * the loop variable as well as the result type of the loop; {@code T}/{@code t}, that of the elements of the
+ * structure the loop iterates over, and {@code A...}/{@code a...} represent arguments passed to the loop.
+ * <blockquote><pre>{@code

+ * Makes a method handle that adapts a {@code target} method handle by wrapping it in a {@code try-finally} block.
+ * Another method handle, {@code cleanup}, represents the functionality of the {@code finally} block. Any exception
+ * thrown during the execution of the {@code target} handle will be passed to the {@code cleanup} handle. The
+ * exception will be rethrown, unless {@code cleanup} handle throws an exception first. The
+ * value returned from the {@code cleanup} handle's execution will be the result of the execution of the
+ * {@code try-finally} handle.
+ * <p>
+ * The {@code cleanup} handle will be passed one or two additional leading arguments.
+ * The first is the exception thrown during the
+ * execution of the {@code target} handle, or {@code null} if no exception was thrown.
+ * The second is the result of the execution of the {@code target} handle, or, if it throws an exception,
+ * a {@code null}, zero, or {@code false} value of the required type is supplied as a placeholder.
+ * The second argument is not present if the {@code target} handle has a {@code void} return type.
+ * (Note that, except for argument type conversions, combinators represent {@code void} values in parameter lists
+ * by omitting the corresponding paradoxical arguments, not by inserting {@code null} or zero values.)
+ * <p>
+ * The {@code target} and {@code cleanup} handles must have the same corresponding argument and return types, except
+ * that the {@code cleanup} handle may omit trailing arguments. Also, the {@code cleanup} handle must have one or
+ * two extra leading parameters:<ul>
+ * <li>a {@code Throwable}, which will carry the exception thrown by the {@code target} handle (if any); and
+ * <li>a parameter of the same type as the return type of both {@code target} and {@code cleanup}, which will carry
+ * the result from the execution of the {@code target} handle.
+ * This parameter is not present if the {@code target} returns {@code void}.
+ * </ul>
+ * <p>
+ * The pseudocode for the resulting adapter looks as follows. In the code, {@code V} represents the result type of
+ * the {@code try/finally} construct; {@code A}/{@code a}, the types and values of arguments to the resulting
+ * handle consumed by the cleanup; and {@code B}/{@code b}, those of arguments to the resulting handle discarded by
+ * the cleanup.
+ * <blockquote><pre>{@code
+ * V target(A..., B...);
+ * V cleanup(Throwable, V, A...);
+ * V adapter(A... a, B... b) {
+ * V result = (zero value for V);
+ * Throwable throwable = null;
+ * try {
+ * result = target(a..., b...);
+ * } catch (Throwable t) {
+ * throwable = t;
+ * throw t;
+ * } finally {
+ * result = cleanup(throwable, result, a...);
+ * }
+ * return result;
+ * }
+ * }</pre></blockquote>
+ * <p>
+ * Note that the saved arguments ({@code a...} in the pseudocode) cannot
+ * be modified by execution of the target, and so are passed unchanged
+ * from the caller to the cleanup, if it is invoked.
+ * <p>
+ * The target and cleanup must return the same type, even if the cleanup
+ * always throws.
+ * To create such a throwing cleanup, compose the cleanup logic
+ * with {@link #throwException throwException},
+ * in order to create a method handle of the correct return type.
+ * <p>
+ * Note that {@code tryFinally} never converts exceptions into normal returns.
+ * In rare cases where exceptions must be converted in that way, first wrap
+ * the target with {@link #catchException(MethodHandle, Class, MethodHandle)}
+ * to capture an outgoing exception, and then wrap with {@code tryFinally}.
+ * <p>
+ * It is recommended that the first parameter type of {@code cleanup} be
+ * declared {@code Throwable} rather than a narrower subtype. This ensures
+ * {@code cleanup} will always be invoked with whatever exception that
+ * {@code target} throws. Declaring a narrower type may result in a
+ * {@code ClassCastException} being thrown by the {@code try-finally}
+ * handle if the type of the exception thrown by {@code target} is not
+ * assignable to the first parameter type of {@code cleanup}. Note that
+ * various exception types of {@code VirtualMachineError},
+ * {@code LinkageError}, and {@code RuntimeException} can in principle be
+ * thrown by almost any kind of Java code, and a finally clause that
+ * catches (say) only {@code IOException} would mask any of the others

+/**
+ * {@code Cleaner} manages a set of object references and corresponding cleaning actions.
+ * <p>
+ * Cleaning actions are {@link #register(Object object, Runnable action) registered}
+ * to run after the cleaner is notified that the object has become
+ * phantom reachable.
+ * The cleaner uses {@link PhantomReference} and {@link ReferenceQueue} to be
+ * notified when the <a href="package-summary.html#reachability">reachability</a>
+ * changes.
+ * <p>
+ * Each cleaner operates independently, managing the pending cleaning actions
+ * and handling threading and termination when the cleaner is no longer in use.
+ * Registering an object reference and corresponding cleaning action returns
+ * a {@link Cleanable Cleanable}. The most efficient use is to explicitly invoke
+ * the {@link Cleanable#clean clean} method when the object is closed or
+ * no longer needed.
+ * The cleaning action is a {@link Runnable} to be invoked at most once when
+ * the object has become phantom reachable unless it has already been explicitly cleaned.
+ * Note that the cleaning action must not refer to the object being registered.
+ * If so, the object will not become phantom reachable and the cleaning action
+ * will not be invoked automatically.
+ * <p>
+ * The execution of the cleaning action is performed
+ * by a thread associated with the cleaner.
+ * All exceptions thrown by the cleaning action are ignored.
+ * The cleaner and other cleaning actions are not affected by
+ * exceptions in a cleaning action.
+ * The thread runs until all registered cleaning actions have
+ * completed and the cleaner itself is reclaimed by the garbage collector.
+ * <p>
+ * The behavior of cleaners during {@link System#exit(int) System.exit}
+ * is implementation specific. No guarantees are made relating
+ * to whether cleaning actions are invoked or not.
+ * <p>
+ * Unless otherwise noted, passing a {@code null} argument to a constructor or
+ * method in this class will cause a
+ * {@link java.lang.NullPointerException NullPointerException} to be thrown.
+ *
+ * @apiNote
+ * The cleaning action is invoked only after the associated object becomes
+ * phantom reachable, so it is important that the object implementing the
+ * cleaning action does not hold references to the object.
+ * In this example, a static class encapsulates the cleaning state and action.
+ * An "inner" class, anonymous or not, must not be used because it implicitly
+ * contains a reference to the outer instance, preventing it from becoming
+ * phantom reachable.
+ * The choice of a new cleaner or sharing an existing cleaner is determined
+ * by the use case.
+ * <p>
+ * If the CleaningExample is used in a try-finally block then the
+ * {@code close} method calls the cleaning action.
+ * If the {@code close} method is not called, the cleaning action is called
+ * by the Cleaner when the CleaningExample instance has become phantom reachable.
+ * <pre>{@code
+ * public class CleaningExample implements AutoCloseable {
+ * // A cleaner, preferably one shared within a library
+ * private static final Cleaner cleaner = <cleaner>;
+ *
+ * static class State implements Runnable {
+ *
+ * State(...) {
+ * // initialize State needed for cleaning action
+ * }
+ *
+ * public void run() {
+ * // cleanup action accessing State, executed at most once
+ * }
+ * }
+ *
+ * private final State;
+ * private final Cleaner.Cleanable cleanable
+ *
+ * public CleaningExample() {
+ * this.state = new State(...);
+ * this.cleanable = cleaner.register(this, state);
+ * }
+ *
+ * public void close() {
+ * cleanable.clean();
+ * }
+ * }
+ * }</pre>
+ * The cleaning action could be a lambda but all too easily will capture
+ * the object reference, by referring to fields of the object being cleaned,
+ * preventing the object from becoming phantom reachable.
+ * Using a static nested class, as above, will avoid accidentally retaining the
+ * object reference.
+ * <p>
+ * <a id="compatible-cleaners"></a>
+ * Cleaning actions should be prepared to be invoked concurrently with
+ * other cleaning actions.
+ * Typically the cleaning actions should be very quick to execute
+ * and not block. If the cleaning action blocks, it may delay processing
+ * other cleaning actions registered to the same cleaner.
+ * All cleaning actions registered to a cleaner should be mutually compatible.

+ * provided, each weaker than the last: <em>soft</em>, <em>weak</em>,

* <h3>Notification</h3>
*
- * A program may request to be notified of changes in an object's reachability by

- * queue</em> at the time the reference object is created. Some time after the
- * garbage collector determines that the reachability of the referent has changed
- * to the value corresponding to the type of the reference, it will add the
- * reference to the associated queue. At this point, the reference is considered
- * to be <em>enqueued</em>. The program may remove references from a queue either
- * by polling or by blocking until a reference becomes available. Reference
- * queues are implemented by the <code>{@link java.lang.ref.ReferenceQueue}</code>
- * class.

- * registered with it. If a registered reference becomes unreachable itself, then

+ * queue is one-sided. That is, a queue does not keep track of the
+ * references that are registered with it. If a registered reference
+ * becomes unreachable itself, then it will never be enqueued. It is
+ * the responsibility of the program using reference objects to ensure
+ * that the objects remain reachable for as long as the program is
+ * interested in their referents.
*
- * <p> While some programs will choose to dedicate a thread to removing reference
- * objects from one or more queues and processing them, this is by no means
- * necessary. A tactic that often works well is to examine a reference queue in
- * the course of performing some other fairly-frequent action. For example, a
- * hashtable that uses weak references to implement weak keys could poll its
- * reference queue each time the table is accessed. This is how the <code>{@link
- * java.util.WeakHashMap}</code> class works. Because the <code>{@link
- * java.lang.ref.ReferenceQueue#poll ReferenceQueue.poll}</code> method simply
- * checks an internal data structure, this check will add little overhead to the
- * hashtable access methods.

+ *
+#end[byte]
+ *
+#if[byte]
+ *
+ * <a id="direct"></a>
+ * <h2> Direct <i>vs.</i> non-direct buffers </h2>
+ *
+ * <p> A byte buffer is either <i>direct</i> or <i>non-direct</i>. Given a
+ * direct byte buffer, the Java virtual machine will make a best effort to
+ * perform native I/O operations directly upon it. That is, it will attempt to
+ * avoid copying the buffer's content to (or from) an intermediate buffer
+ * before (or after) each invocation of one of the underlying operating
+ * system's native I/O operations.
+ *
+ * <p> A direct byte buffer may be created by invoking the {@link
+ * #allocateDirect(int) allocateDirect} factory method of this class. The
+ * buffers returned by this method typically have somewhat higher allocation
+ * and deallocation costs than non-direct buffers. The contents of direct
+ * buffers may reside outside of the normal garbage-collected heap, and so
+ * their impact upon the memory footprint of an application might not be
+ * obvious. It is therefore recommended that direct buffers be allocated
+ * primarily for large, long-lived buffers that are subject to the underlying
+ * system's native I/O operations. In general it is best to allocate direct
+ * buffers only when they yield a measureable gain in program performance.
+ *
+ * <p> A direct byte buffer may also be created by {@link
+ * java.nio.channels.FileChannel#map mapping} a region of a file
+ * directly into memory. An implementation of the Java platform may optionally
+ * support the creation of direct byte buffers from native code via JNI. If an
+ * instance of one of these kinds of buffers refers to an inaccessible region
+ * of memory then an attempt to access that region will not change the buffer's
+ * content and will cause an unspecified exception to be thrown either at the
+ * time of the access or at some later time.
+ *
+ * <p> Whether a byte buffer is direct or non-direct may be determined by
+ * invoking its {@link #isDirect isDirect} method. This method is provided so
+ * that explicit buffer management can be done in performance-critical code.
+ *
+ *
+ * <a id="bin"></a>
+ * <h2> Access to binary data </h2>
+ *
+ * <p> This class defines methods for reading and writing values of all other
+ * primitive types, except {@code boolean}. Primitive values are translated
+ * to (or from) sequences of bytes according to the buffer's current byte
+ * order, which may be retrieved and modified via the {@link #order order}
+ * methods. Specific byte orders are represented by instances of the {@link
+ * ByteOrder} class. The initial order of a byte buffer is always {@link
+ * ByteOrder#BIG_ENDIAN BIG_ENDIAN}.
+ *
+ * <p> For access to heterogeneous binary data, that is, sequences of values of
+ * different types, this class defines a family of absolute and relative
+ * <i>get</i> and <i>put</i> methods for each type. For 32-bit floating-point
+ * values, for example, this class defines:
+ *
+ * <blockquote><pre>
+ * float {@link #getFloat()}
+ * float {@link #getFloat(int) getFloat(int index)}
+ * void {@link #putFloat(float) putFloat(float f)}
+ * void {@link #putFloat(int,float) putFloat(int index, float f)}</pre></blockquote>
+ *
+ * <p> Corresponding methods are defined for the types {@code char,
+ * short, int, long}, and {@code double}. The index
+ * parameters of the absolute <i>get</i> and <i>put</i> methods are in terms of
+ * bytes rather than of the type being read or written.
+ *
+ * <a id="views"></a>
+ *
+ * <p> For access to homogeneous binary data, that is, sequences of values of
+ * the same type, this class defines methods that can create <i>views</i> of a
+ * given byte buffer. A <i>view buffer</i> is simply another buffer whose
+ * content is backed by the byte buffer. Changes to the byte buffer's content
+ * will be visible in the view buffer, and vice versa; the two buffers'
+ * position, limit, and mark values are independent. The {@link
+ * #asFloatBuffer() asFloatBuffer} method, for example, creates an instance of
+ * the {@link FloatBuffer} class that is backed by the byte buffer upon which
+ * the method is invoked. Corresponding view-creation methods are defined for
+ * the types {@code char, short, int, long}, and {@code double}.
+ *
+ * <p> View buffers have three important advantages over the families of
+ * type-specific <i>get</i> and <i>put</i> methods described above:
+ *
+ * <ul>
+ *
+ * <li><p> A view buffer is indexed not in terms of bytes but rather in terms
+ * of the type-specific size of its values; </p></li>
+ *
+ * <li><p> A view buffer provides relative bulk <i>get</i> and <i>put</i>
+ * methods that can transfer contiguous sequences of values between a buffer
+ * and an array or some other buffer of the same type; and </p></li>
+ *
+ * <li><p> A view buffer is potentially much more efficient because it will
+ * be direct if, and only if, its backing byte buffer is direct. </p></li>
+ *
+ * </ul>
+ *
+ * <p> The byte order of a view buffer is fixed to be that of its byte buffer
+ * at the time that the view is created. </p>
+ *
+#end[byte]
+*
+#if[!byte]
+ *
+ * <p> Like a byte buffer, $a$ $type$ buffer is either <a
+ * href="ByteBuffer.html#direct"><i>direct</i> or <i>non-direct</i></a>. A
+ * $type$ buffer created via the {@code wrap} methods of this class will
+ * be non-direct. $A$ $type$ buffer created as a view of a byte buffer will
+ * be direct if, and only if, the byte buffer itself is direct. Whether or not
+ * $a$ $type$ buffer is direct may be determined by invoking the {@link
+ * #isDirect isDirect} method. </p>
+ *
+#end[!byte]
+*
+#if[char]
+ *
+ * <p> This class implements the {@link CharSequence} interface so that
+ * character buffers may be used wherever character sequences are accepted, for
+ * example in the regular-expression package {@link java.util.regex}.
+ * </p>
+ *
+#end[char]
+ *
+#if[byte]
+ * <h2> Invocation chaining </h2>
+#end[byte]
+ *
+ * <p> Methods in this class that do not otherwise have a value to return are
+ * specified to return the buffer upon which they are invoked. This allows
+ * method invocations to be chained.
+ *
+#if[byte]
+ *
+ * The sequence of statements
+ *
+ * <blockquote><pre>
+ * bb.putInt(0xCAFEBABE);
+ * bb.putShort(3);
+ * bb.putShort(45);</pre></blockquote>

+ *
+ * <p>Most collections manage storage for elements they contain. By contrast, <i>view
+ * collections</i> themselves do not store elements, but instead they rely on a
+ * backing collection to store the actual elements. Operations that are not handled
+ * by the view collection itself are delegated to the backing collection. Examples of
+ * view collections include the wrapper collections returned by methods such as
+ * {@link Collections#checkedCollection Collections.checkedCollection},
+ * {@link Collections#synchronizedCollection Collections.synchronizedCollection}, and
+ * {@link Collections#unmodifiableCollection Collections.unmodifiableCollection}.
+ * Other examples of view collections include collections that provide a
+ * different representation of the same elements, for example, as
+ * provided by {@link List#subList List.subList},
+ * {@link NavigableSet#subSet NavigableSet.subSet}, or
+ * {@link Map#entrySet Map.entrySet}.
+ * Any changes made to the backing collection are visible in the view collection.
+ * Correspondingly, any changes made to the view collection — if changes
+ * are permitted — are written through to the backing collection.
+ * Although they technically aren't collections, instances of
+ * {@link Iterator} and {@link ListIterator} can also allow modifications
+ * to be written through to the backing collection, and in some cases,
+ * modifications to the backing collection will be visible to the Iterator
+ * during iteration.
+ *
+ * <h2><a id="unmodifiable">Unmodifiable Collections</a></h2>
+ *
+ * <p>Certain methods of this interface are considered "destructive" and are called
+ * "mutator" methods in that they modify the group of objects contained within
+ * the collection on which they operate. They can be specified to throw
+ * {@code UnsupportedOperationException} if this collection implementation
+ * does not support the operation. Such methods should (but are not required
+ * to) throw an {@code UnsupportedOperationException} if the invocation would
+ * have no effect on the collection. For example, consider a collection that
+ * does not support the {@link #add add} operation. What will happen if the
+ * {@link #addAll addAll} method is invoked on this collection, with an empty
+ * collection as the argument? The addition of zero elements has no effect,
+ * so it is permissible for this collection simply to do nothing and not to throw
+ * an exception. However, it is recommended that such cases throw an exception
+ * unconditionally, as throwing only in certain cases can lead to
+ * programming errors.
+ *
+ * <p>An <i>unmodifiable collection</i> is a collection, all of whose
+ * mutator methods (as defined above) are specified to throw
+ * {@code UnsupportedOperationException}. Such a collection thus cannot be
+ * modified by calling any methods on it. For a collection to be properly
+ * unmodifiable, any view collections derived from it must also be unmodifiable.
+ * For example, if a List is unmodifiable, the List returned by
+ * {@link List#subList List.subList} is also unmodifiable.
+ *
+ * <p>An unmodifiable collection is not necessarily immutable. If the
+ * contained elements are mutable, the entire collection is clearly
+ * mutable, even though it might be unmodifiable. For example, consider
+ * two unmodifiable lists containing mutable elements. The result of calling
+ * {@code list1.equals(list2)} might differ from one call to the next if
+ * the elements had been mutated, even though both lists are unmodifiable.
+ * However, if an unmodifiable collection contains all immutable elements,
+ * it can be considered effectively immutable.
+ *
+ * <h2><a id="unmodview">Unmodifiable View Collections</a></h2>
+ *
+ * <p>An <i>unmodifiable view collection</i> is a collection that is unmodifiable
+ * and that is also a view onto a backing collection. Its mutator methods throw
+ * {@code UnsupportedOperationException}, as described above, while
+ * reading and querying methods are delegated to the backing collection.
+ * The effect is to provide read-only access to the backing collection.
+ * This is useful for a component to provide users with read access to
+ * an internal collection, while preventing them from modifying such
+ * collections unexpectedly. Examples of unmodifiable view collections
+ * are those returned by the
+ * {@link Collections#unmodifiableCollection Collections.unmodifiableCollection},
+ * {@link Collections#unmodifiableList Collections.unmodifiableList}, and
+ * related methods.
+ *
+ * <p>Note that changes to the backing collection might still be possible,
+ * and if they occur, they are visible through the unmodifiable view. Thus,
+ * an unmodifiable view collection is not necessarily immutable. However,
+ * if the backing collection of an unmodifiable view is effectively immutable,
+ * or if the only reference to the backing collection is through an
+ * unmodifiable view, the view can be considered effectively immutable.

+ * (volatile) CAS, placing an acquireFence in a few access
+ * methods, and ensuring that linked objects are transitively
+ * acquired via dependent reads (normally once) unless performing
+ * a volatile-mode CAS operation (that also acts as an acquire and
+ * release). This form of fence-hoisting is similar to RCU and
+ * related techniques (see McKenney's online book
+ * https://www.kernel.org/pub/linux/kernel/people/paulmck/perfbook/perfbook.html)
+ * It minimizes overhead that may otherwise occur when using so
+ * many volatile-mode reads. Using explicit acquireFences is
+ * logistically easier than targeting particular fields to be read
+ * in acquire mode: fences are just hoisted up as far as possible,
+ * to the entry points or loop headers of a few methods. A
+ * potential disadvantage is that these few remaining fences are
+ * not easily optimized away by compilers under exclusively
+ * single-thread use. It requires some care to avoid volatile
+ * mode reads of other fields. (Note that the memory semantics of
+ * a reference dependently read in plain mode exactly once are
+ * equivalent to those for atomic opaque mode.) Iterators and
+ * other traversals encounter each node and value exactly once.
+ * Other operations locate an element (or position to insert an
+ * element) via a sequence of dereferences. This search is broken
+ * into two parts. Method findPredecessor (and its specialized
+ * embeddings) searches index nodes only, returning a base-level
+ * predecessor of the key. Callers carry out the base-level
+ * search, restarting if encountering a marker preventing link
+ * modification. In some cases, it is possible to encounter a
+ * node multiple times while descending levels. For mutative
+ * operations, the reported value is validated using CAS (else
+ * retrying), preserving linearizability with respect to each
+ * other. Others may return any (non-null) value holding in the
+ * course of the method call. (Search-based methods also include
+ * some useless-looking explicit null checks designed to allow
+ * more fields to be nulled out upon removal, to reduce floating
+ * garbage, but which is not currently done, pending discovery of
+ * a way to do this with less impact on other operations.)
*
* To produce random values without interference across threads,
* we use within-JDK thread local random support (via the
* "secondary seed", to avoid interference with user-level
* ThreadLocalRandom.)
*
- * A previous version of this class wrapped non-comparable keys
- * with their comparators to emulate Comparables when using
- * comparators vs Comparables. However, JVMs now appear to better
- * handle infusing comparator-vs-comparable choice into search
- * loops. Static method cpr(comparator, x, y) is used for all
- * comparisons, which works well as long as the comparator
- * argument is set up outside of loops (thus sometimes passed as
- * an argument to internal methods) to avoid field re-reads.
- *
* For explanation of algorithms sharing at least a couple of
* features with this one, see Mikhail Fomitchev's thesis
* (http://www.cs.yorku.ca/~mikhail/), Keir Fraser's thesis
* (http://www.cl.cam.ac.uk/users/kaf24/), and Hakan Sundell's
* thesis (http://www.cs.chalmers.se/~phs/).
*
- * Given the use of tree-like index nodes, you might wonder why
- * this doesn't use some kind of search tree instead, which would
- * support somewhat faster search operations. The reason is that
- * there are no known efficient lock-free insertion and deletion
- * algorithms for search trees. The immutability of the "down"
- * links of index nodes (as opposed to mutable "left" fields in
- * true trees) makes this tractable using only CAS operations.

* This design can be improved by noticing that in the recursive case,
* the task has nothing to do after forking its right task, so can
* directly invoke its left task before returning. (This is an analog
- * of tail recursion removal.) Also, because the task returns upon
- * executing its left task (rather than falling through to invoke
- * {@code tryComplete}) the pending count is set to one:
+ * of tail recursion removal.) Also, when the last action in a task
+ * is to fork or invoke a subtask (a "tail call"), the call to {@code
+ * tryComplete()} can be optimized away, at the cost of making the
+ * pending count look "off by one".
*
* <pre> {@code
- * class ForEach<E> ... {
- * ...
- * public void compute() { // version 2

+ * } else {
+ * if (hi > lo)
+ * action.accept(array[lo]);
+ * tryComplete();
+ * }
+ * }}</pre>
*
* As a further optimization, notice that the left task need not even exist.
- * Instead of creating a new one, we can iterate using the original task,
+ * Instead of creating a new one, we can continue using the original task,
* and add a pending count for each fork. Additionally, because no task
* in this tree implements an {@link #onCompletion(CountedCompleter)} method,
- * {@code tryComplete()} can be replaced with {@link #propagateCompletion}.

+ * the given maximumPoolSize. For the default value, use {@code
+ * 1}, that ensures liveness. A larger value might improve
+ * throughput in the presence of blocked activities, but might
+ * not, due to increased overhead. A value of zero may be
+ * acceptable when submitted tasks cannot have dependencies
+ * requiring additional threads.
+ *
+ * @param saturate if non-null, a predicate invoked upon attempts
+ * to create more than the maximum total allowed threads. By
+ * default, when a thread is about to block on a join or {@link
+ * ManagedBlocker}, but cannot be replaced because the
+ * maximumPoolSize would be exceeded, a {@link
+ * RejectedExecutionException} is thrown. But if this predicate
+ * returns {@code true}, then no exception is thrown, so the pool
+ * continues to operate with fewer than the target number of
+ * runnable threads, which might not ensure progress.
+ *
+ * @param keepAliveTime the elapsed time since last use before
+ * a thread is terminated (and then later replaced if needed).

+/**
+ * A {@link Flow.Publisher} that asynchronously issues submitted
+ * (non-null) items to current subscribers until it is closed. Each
+ * current subscriber receives newly submitted items in the same order
+ * unless drops or exceptions are encountered. Using a
+ * SubmissionPublisher allows item generators to act as compliant <a
+ * href="http://www.reactive-streams.org/"> reactive-streams</a>
+ * Publishers relying on drop handling and/or blocking for flow
+ * control.
+ *
+ * <p>A SubmissionPublisher uses the {@link Executor} supplied in its
+ * constructor for delivery to subscribers. The best choice of
+ * Executor depends on expected usage. If the generator(s) of
+ * submitted items run in separate threads, and the number of
+ * subscribers can be estimated, consider using a {@link
+ * Executors#newFixedThreadPool}. Otherwise consider using the
+ * default, normally the {@link ForkJoinPool#commonPool}.
+ *
+ * <p>Buffering allows producers and consumers to transiently operate
+ * at different rates. Each subscriber uses an independent buffer.
+ * Buffers are created upon first use and expanded as needed up to the
+ * given maximum. (The enforced capacity may be rounded up to the
+ * nearest power of two and/or bounded by the largest value supported
+ * by this implementation.) Invocations of {@link
+ * Flow.Subscription#request(long) request} do not directly result in
+ * buffer expansion, but risk saturation if unfilled requests exceed
+ * the maximum capacity. The default value of {@link
+ * Flow#defaultBufferSize()} may provide a useful starting point for
+ * choosing a capacity based on expected rates, resources, and usages.
+ *
+ * <p>A single SubmissionPublisher may be shared among multiple
+ * sources. Actions in a source thread prior to publishing an item or
+ * issuing a signal <a href="package-summary.html#MemoryVisibility">
+ * <i>happen-before</i></a> actions subsequent to the corresponding
+ * access by each subscriber. But reported estimates of lag and demand
+ * are designed for use in monitoring, not for synchronization
+ * control, and may reflect stale or inaccurate views of progress.
+ *
+ * <p>Publication methods support different policies about what to do
+ * when buffers are saturated. Method {@link #submit(Object) submit}
+ * blocks until resources are available. This is simplest, but least
+ * responsive. The {@code offer} methods may drop items (either
+ * immediately or with bounded timeout), but provide an opportunity to
+ * interpose a handler and then retry.
+ *
+ * <p>If any Subscriber method throws an exception, its subscription
+ * is cancelled. If a handler is supplied as a constructor argument,
+ * it is invoked before cancellation upon an exception in method
+ * {@link Flow.Subscriber#onNext onNext}, but exceptions in methods
+ * {@link Flow.Subscriber#onSubscribe onSubscribe},
+ * {@link Flow.Subscriber#onError(Throwable) onError} and
+ * {@link Flow.Subscriber#onComplete() onComplete} are not recorded or
+ * handled before cancellation. If the supplied Executor throws
+ * {@link RejectedExecutionException} (or any other RuntimeException
+ * or Error) when attempting to execute a task, or a drop handler
+ * throws an exception when processing a dropped item, then the
+ * exception is rethrown. In these cases, not all subscribers will
+ * have been issued the published item. It is usually good practice to
+ * {@link #closeExceptionally closeExceptionally} in these cases.
+ *
+ * <p>Method {@link #consume(Consumer)} simplifies support for a
+ * common case in which the only action of a subscriber is to request
+ * and process all items using a supplied function.
+ *
+ * <p>This class may also serve as a convenient base for subclasses
+ * that generate items, and use the methods in this class to publish
+ * them. For example here is a class that periodically publishes the
+ * items generated from a supplier. (In practice you might add methods
+ * to independently start and stop generation, to share Executors
+ * among publishers, and so on, or use a SubmissionPublisher as a
+ * component rather than a superclass.)

+ * primarily on atomic operations (CAS or getAndSet) at the next
+ * array slot to put or take an element, at the "tail" and "head"
+ * indices written only by the producer and consumer respectively.
+ *
+ * We ensure internally that there is at most one active consumer
+ * task at any given time. The publisher guarantees a single
+ * producer via its lock. Sync among producers and consumers
+ * relies on volatile fields "ctl", "demand", and "waiting" (along
+ * with element access). Other variables are accessed in plain
+ * mode, relying on outer ordering and exclusion, and/or enclosing
+ * them within other volatile accesses. Some atomic operations are
+ * avoided by tracking single threaded ownership by producers (in
+ * the style of biased locking).
+ *
+ * Execution control and protocol state are managed using field
+ * "ctl". Methods to subscribe, close, request, and cancel set
+ * ctl bits (mostly using atomic boolean method getAndBitwiseOr),
+ * and ensure that a task is running. (The corresponding consumer
+ * side actions are in method consume.) To avoid starting a new
+ * task on each action, ctl also includes a keep-alive bit
+ * (ACTIVE) that is refreshed if needed on producer actions.
+ * (Maintaining agreement about keep-alives requires most atomic
+ * updates to be full SC/Volatile strength, which is still much
+ * cheaper than using one task per item.) Error signals
+ * additionally null out items and/or fields to reduce termination
+ * latency. The cancel() method is supported by treating as ERROR
+ * but suppressing onError signal.
+ *
+ * Support for blocking also exploits the fact that there is only
+ * one possible waiter. ManagedBlocker-compatible control fields
+ * are placed in this class itself rather than in wait-nodes.
+ * Blocking control relies on the "waiting" and "waiter"
+ * fields. Producers set them before trying to block. Signalling
+ * unparks and clears fields. If the producer and/or consumer are
+ * using a ForkJoinPool, the producer attempts to help run
+ * consumer tasks via ForkJoinPool.helpAsyncBlocker before
+ * blocking.
+ *
+ * Usages of this class may encounter any of several forms of
+ * memory contention. We try to ameliorate across them without
+ * unduly impacting footprints in low-contention usages where it
+ * isn't needed. Buffer arrays start out small and grow only as
+ * needed. The class uses @Contended and heuristic field
+ * declaration ordering to reduce false-sharing memory contention
+ * across instances of BufferedSubscription (as in, multiple
+ * subscribers per publisher). We additionally segregate some
+ * fields that would otherwise nearly always encounter cache line
+ * contention among producers and consumers. To reduce contention
+ * across time (vs space), consumers only periodically update
+ * other fields (see method takeItems), at the expense of possibly
+ * staler reporting of lags and demand (bounded at 12.5% == 1/8
+ * capacity) and possibly more atomic operations.
+ *
+ * Other forms of imbalance and slowdowns can occur during startup
+ * when producer and consumer methods are compiled and/or memory
+ * is allocated at different rates. This is ameliorated by
+ * artificially subdividing some consumer methods, including
+ * isolation of all subscriber callbacks. This code also includes
+ * typical power-of-two array screening idioms to avoid compilers
+ * generating traps, along with the usual SSA-based inline
+ * assignment coding style. Also, all methods and fields have
+ * default visibility to simplify usage by callers.

+
+// Android-note: HotSpot-specific implementation notes not relevant for Android.
+/**
+ * The {@code @HotSpotIntrinsicCandidate} annotation is specific to the
+ * HotSpot Virtual Machine. It indicates that an annotated method
+ * may be (but is not guaranteed to be) intrinsified by the HotSpot VM. A method
+ * is intrinsified if the HotSpot VM replaces the annotated method with hand-written
+ * assembly and/or hand-written compiler IR -- a compiler intrinsic -- to improve
+ * performance. The {@code @HotSpotIntrinsicCandidate} annotation is internal to the
+ * Java libraries and is therefore not supposed to have any relevance for application
+ * code.
+ *
+ * Maintainers of the Java libraries must consider the following when
+ * modifying methods annotated with {@code @HotSpotIntrinsicCandidate}.
+ *
+ * <ul>
+ * <li>When modifying a method annotated with {@code @HotSpotIntrinsicCandidate},
+ * the corresponding intrinsic code in the HotSpot VM implementation must be
+ * updated to match the semantics of the annotated method.</li>
+ * <li>For some annotated methods, the corresponding intrinsic may omit some low-level
+ * checks that would be performed as a matter of course if the intrinsic is implemented
+ * using Java bytecodes. This is because individual Java bytecodes implicitly check
+ * for exceptions like {@code NullPointerException} and {@code ArrayStoreException}.
+ * If such a method is replaced by an intrinsic coded in assembly language, any
+ * checks performed as a matter of normal bytecode operation must be performed
+ * before entry into the assembly code. These checks must be performed, as
+ * appropriate, on all arguments to the intrinsic, and on other values (if any) obtained
+ * by the intrinsic through those arguments. The checks may be deduced by inspecting
+ * the non-intrinsic Java code for the method, and determining exactly which exceptions
+ * may be thrown by the code, including undeclared implicit {@code RuntimeException}s.
+ * Therefore, depending on the data accesses performed by the intrinsic,
+ * the checks may include:
+ *
+ * <ul>
+ * <li>null checks on references</li>
+ * <li>range checks on primitive values used as array indexes</li>
+ * <li>other validity checks on primitive values (e.g., for divide-by-zero conditions)</li>
+ * <li>store checks on reference values stored into arrays</li>
+ * <li>array length checks on arrays indexed from within the intrinsic</li>
+ * <li>reference casts (when formal parameters are {@code Object} or some other weak type)</li>
+ * </ul>
+ *
+ * </li>
+ *
+ * <li>Note that the receiver value ({@code this}) is passed as a extra argument
+ * to all non-static methods. If a non-static method is an intrinsic, the receiver
+ * value does not need a null check, but (as stated above) any values loaded by the
+ * intrinsic from object fields must also be checked. As a matter of clarity, it is
+ * better to make intrinisics be static methods, to make the dependency on {@code this}
+ * clear. Also, it is better to explicitly load all required values from object
+ * fields before entering the intrinsic code, and pass those values as explicit arguments.
+ * First, this may be necessary for null checks (or other checks). Second, if the
+ * intrinsic reloads the values from fields and operates on those without checks,
+ * race conditions may be able to introduce unchecked invalid values into the intrinsic.
+ * If the intrinsic needs to store a value back to an object field, that value should be
+ * returned explicitly from the intrinsic; if there are multiple return values, coders
+ * should consider buffering them in an array. Removing field access from intrinsics
+ * not only clarifies the interface with between the JVM and JDK; it also helps decouple
+ * the HotSpot and JDK implementations, since if JDK code before and after the intrinsic
+ * manages all field accesses, then intrinsics can be coded to be agnostic of object
+ * layouts.</li>
+ *
+ * Maintainers of the HotSpot VM must consider the following when modifying
+ * intrinsics.
+ *
+ * <ul>
+ * <li>When adding a new intrinsic, make sure that the corresponding method
+ * in the Java libraries is annotated with {@code @HotSpotIntrinsicCandidate}
+ * and that all possible call sequences that result in calling the intrinsic contain
+ * the checks omitted by the intrinsic (if any).</li>
+ * <li>When modifying an existing intrinsic, the Java libraries must be updated
+ * to match the semantics of the intrinsic and to execute all checks omitted
+ * by the intrinsic (if any).</li>
+ * </ul>
+ *
+ * Persons not directly involved with maintaining the Java libraries or the
+ * HotSpot VM can safely ignore the fact that a method is annotated with
+ * {@code @HotSpotIntrinsicCandidate}.
+ *
+ * The HotSpot VM defines (internally) a list of intrinsics. Not all intrinsic
+ * are available on all platforms supported by the HotSpot VM. Furthermore,
+ * the availability of an intrinsic on a given platform depends on the
+ * configuration of the HotSpot VM (e.g., the set of VM flags enabled).
+ * Therefore, annotating a method with {@code @HotSpotIntrinsicCandidate} does
+ * not guarantee that the marked method is intrinsified by the HotSpot VM.
+ *
+ * If the {@code CheckIntrinsics} VM flag is enabled, the HotSpot VM checks
+ * (when loading a class) that (1) all methods of that class that are also on
+ * the VM's list of intrinsics are annotated with {@code @HotSpotIntrinsicCandidate}
+ * and that (2) for all methods of that class annotated with
+ * {@code @HotSpotIntrinsicCandidate} there is an intrinsic in the list.
+ *
+ * @since 9

+ * finalizer thread. They are more robust because they use phantom references,

+ * <p> A cleaner tracks a referent object and encapsulates a thunk of arbitrary
+ * cleanup code. Some time after the GC detects that a cleaner's referent has
+ * become phantom-reachable, the reference-handler thread will run the cleaner.
+ * Cleaners may also be invoked directly; they are thread safe and ensure that
+ * they run their thunks at most once.
+ *
+ * <p> Cleaners are not a replacement for finalization. They should be used
+ * only when the cleanup code is extremely simple and straightforward.

+ * <p>The mismatch method implementation, {@link #vectorizedMismatch}, leverages

+ * The Java implementation uses {@code Unsafe.getLongUnaligned} to access the

+ * (256 bits), and perhaps in the future even 64 bytes (512 bits), platform
+ * permitting, can be accessed and compared as a unit, which further increases

+/**
+ * <p>An annotation expressing that objects and/or their fields are
+ * expected to encounter memory contention, generally in the form of
+ * "false sharing". This annotation serves as a hint that such objects
+ * and fields should reside in locations isolated from those of other
+ * objects or fields. Susceptibility to memory contention is a
+ * property of the intended usages of objects and fields, not their
+ * types or qualifiers. The effects of this annotation will nearly
+ * always add significant space overhead to objects. The use of
+ * {@code @Contended} is warranted only when the performance impact of
+ * this time/space tradeoff is intrinsically worthwhile; for example,
+ * in concurrent contexts in which each instance of the annotated
+ * class is often accessed by a different thread.
+ *
+ * <p>A {@code @Contended} field annotation may optionally include a
+ * <i>contention group</i> tag. A contention group defines a set of one
+ * or more fields that collectively must be isolated from all other
+ * contention groups. The fields in the same contention group may not be
+ * pairwise isolated. With no contention group tag (or with the default
+ * empty tag: "") each {@code @Contended} field resides in its own
+ * <i>distinct</i> and <i>anonymous</i> contention group.
+ *
+ * <p>When the annotation is used at the class level, the effect is
+ * equivalent to grouping all the declared fields not already having the
+ * {@code @Contended} annotation into the same anonymous group.
+ * With the class level annotation, implementations may choose different
+ * isolation techniques, such as isolating the entire object, rather than
+ * isolating distinct fields. A contention group tag has no meaning
+ * in a class level {@code @Contended} annotation, and is ignored.
+ *
+ * <p>The class level {@code @Contended} annotation is not inherited and has
+ * no effect on the fields declared in any sub-classes. The effects of all
+ * {@code @Contended} annotations, however, remain in force for all
+ * subclass instances, providing isolation of all the defined contention
+ * groups. Contention group tags are not inherited, and the same tag used
+ * in a superclass and subclass, represent distinct contention groups.

+ * the math library. See http://perso.ens-lyon.fr/jean-michel.muller/TMD.html for original test
+ * vectors from 2000 and see http://perso.ens-lyon.fr/jean-michel.muller/TMDworstcases.pdf with
+ * additional test vectors from 2003. The latter link also contains some information about the
+ * methodology used to produce the test vectors.
+ *
+ * Most of the Java math library methods tested here have a 1-ulp error bound from their
+ * specifications. This implies the returned value must be one of the two representable
+ * floating-point numbers bracketing the exact result. The expected value in the test vectors below
+ * is the truncation of the exact value. Therefore, the computed result must either be that value
+ * or the value next larger in magnitude. The hyperbolic transcendental functions sinh and cosh
+ * have a larger 2.5 ulp error bound in their specification, but the JDK implementation complies
+ * with a 1 ulp bound on the worst-case values. Therefore, no addition leeway is afforded when
+ * testing sinh and cosh.

+ * x = k*ln2 + r, |r| <= 0.5*ln2.
+ *
+ * Here r will be represented as r = hi-lo for better accuracy.
+ *
+ * 2. Approximation of exp(r) by a special rational function on the interval [0,0.34658]: Write
+ * R(r**2) = r*(exp(r)+1)/(exp(r)-1) = 2 + r*r/6 - r**4/360 + ... We use a special Reme
+ * algorithm on [0,0.34658] to generate a polynomial of degree 5 to approximate R. The maximum
+ * error of this polynomial approximation is bounded by 2**-59. In other words, R(z) ~ 2.0 +
+ * P1*z + P2*z**2 + P3*z**3 + P4*z**4 + P5*z**5 (where z=r*r, and the values of P1 to P5 are
+ * listed below) and | 5 | -59 | 2.0+P1*z+...+P5*z - R(z) | <=
+ * 2 | | The computation of exp(r) thus becomes 2*r exp(r) = 1 +
+ * ------- R - r r*R1(r) = 1 + r + ----------- (for better accuracy) 2 - R1(r) where 2 4
+ * 10 R1(r) = r - (P1*r + P2*r + ... + P5*r ).
+ *
+ * 3. Scale back to obtain exp(x): From step 1, we have exp(x) = 2^k * exp(r)
+ *
+ * Special cases: exp(INF) is INF, exp(NaN) is NaN; exp(-INF) is 0, and for finite argument,
+ * only exp(0)=1 is exact.
+ *
+ * Accuracy: according to an error analysis, the error is always less than 1 ulp (unit in the
+ * last place).
+ *
+ * Misc. info. For IEEE double if x > 7.09782712893383973096e+02 then exp(x) overflow if x <

+If you want to import files from the OpenJDK into `libcore/`, you are reading
+the right documentation.
+
+The general idea is to get a change from OpenJDK into libcore in AOSP by
+`git merge` from an OpenJDK branch. However, each file in `ojluni/` can come
+from a different OpenJDK version. `expected_upstream` is a staging branch
+storing the OpenJDK version of each file. Thus, we can use `git merge` when
+we update an `ojluni/` file from a new upstream version, and the command should
+automatically merge the file if no merge conflict.
+
+# Directory Layout
+in the `aosp/expected_upstream` branch.
+1. `ojluni/`
+ * It has the same layout as the ojluni/ files in `aosp/master`
+2. `EXPECTED_UPSTREAM` file
+ * The table has 3 columns, i.e.
+ 1. Destination path in `ojluni/`
+ 2. Expected upstream version / an upstream git tag
+ 3. Upstream source path
+ * The file format is like .csv file using a `,` separator
+3. `tools/expected_upstream/`
+ * Contains the tools
+
+# Understanding your change
+## Changes that shouldn't happen in the `aosp/expected_upstream` branch
+In general, if you want to change an `ojluni/` file by a text editor / IDE
+manually, you should make the change on `aosp/master`.
+
+1. Changes to non-OpenJDK files
+ * Those files are usually under the `luni/` folder, you can make the change
+ directly on `aosp/master`
+2. Adding / updating a patch to an existing `ojluni/` file
+ * You can make the change directly on `aosp/master`. Please follow this
+ [patch style guideline](https://goto.google.com/libcore-openjdk8-verify).
+3. Cherry-picking a commit from upstream
+ * You should first try to update an `ojluni/` file to a particular upstream
+ version. If you can't but still want to cherry-pick a upstream fix, you
+ should do so on the `aosp/master` branch.
+4. Changes to non-OpenJDK files in `ojluni/`
+ * Files, e.g. Android.bp, don't come from the upstream. You can make the
+ change directly on `aosp/master`.
+
+## Changes that should be made via the `aosp/expected_upstream` branch
+
+1. Add or upgrade a file from the upstream OpenJDK
+ * You are reading the right document! This documentation tells you how to
+ import the file from the upstream. Later, you can merge the file and
+ `expected_upstream` into `aosp/master` branch.
+2. Remove an `ojluni/` file that originally came from the OpenJDK
+ * Please remove the file on both `aosp/master` and `aosp/expected_upstream`
+ branches. Don't forget to remove the entry in the `EXPECTED_UPSTREAM` too.
+3. Revert the merge commit on `aosp/master` from `expected_upstream`
+ * If you don't plan to re-land your change on `aosp/master`, you should
+ probably revert the change `aosp/expected_upstream` as well.
+ * If you plan to re-land your change, your re-landing commit won't be
+ a merge commit, because `git` doesn't allow you to merge the same commit
+ twice into the same branch. You have 2 options
+ 1. Revert your change on `expected_upsteam` too and start over again
+ when you reland your change
+ 2. Just accept that the re-landing commit won't be a merge commit.
+
+## Life of a typical change
+
+Commit graph of a typical change
+```text
+----11.0.13-ga---------------- openjdk/jdk11u
+ \
+ A
+ \
+------------B-----C------------ expected_upstream
+ \
+--------------------D---E------ master
+```
+
+Typically, you will need 5 CLs
+* Commit `A` imports the file and moves the file in the `ojluni/` folder
+* Commit `B` merges the file into the expected_upstream with other `ojluni`
+ files
+ * Commit `A` and `B` are created by the `ojluni_refresh_files` script
+* Commit `C` edits the entry in the `EXPECTED_UPSTREAM` file
+* Commit `D` is a merge commit created by `git merge`
+* Commit `E` adds Android patches
+ * Includes other changes to non-OpenJDK files, e.g. `Android.bp`,
+ `api/current.txt`.
+
+### Why can't have a single commit to replace the commits `A`, `B` and `C`?
+* Preserve the upstream history. We can later `git blame` with the upstream
+ history.
+
+# Tools
+
+## Prerequisite
+* python3
+* pip3
+* A remote `aosp` is setup in your local git repository
+
+## List of the scripts
+### tools/expected_upstream/install_tools.sh
+* Installs the dependency libraries
+* Installs the other tools into your current shell process
+
+### ojluni_modify_expectation
+* Command line tool that can help modify the EXPECTED_UPSTREAM file
+
+### ojluni_refresh_files
+* Reads the EXPECTED_UPSTREAM file and updates the files contents in ojluni/
+accordingly
+
+## Workflow in command lines
+### Setup
+1. Switch to the expected_upstream branch
+```shell
+git branch <local_branch> aosp/expected_upstream
+git checkout <local_branch>
+```
+
+2. Install tools
+```shell
+source ./tools/expected_upstream/install_tools.sh
+```
+## Upgrade a java class to a higher OpenJDK version
+For example, upgrade `java.lang.String` to 11.0.13-ga version:
+
+```shell
+ojluni_modify_expectation modify java.lang.String jdk11u/jdk-11.0.13-ga
+ojluni_refresh_files
+```
+
+or if `java.lang.String` is missing in EXPECTED_UPSTREAM:
+```shell
+ojluni_modify_expectation add jdk11u/jdk-11.0.13-ga java.lang.String
+ojluni_refresh_files
+```
+2 commits should be created to update the `ojluni/src/main/java/java/lang/String.java`.
+You can verify and view the diff by the following command
+
+```shell
+git diff aosp/expected_upstream -- ojluni/src/main/java/java/lang/String.java
+```
+
+You can then upload your change to AOSP gerrit.
+```shell
+repo upload --cbr -t . # -t sets a topic to the CLs in the gerrit
+```
+
+Remember to commit your EXPECTED_UPSTREAM file change into a new commit
+```shell
+git commit -- EXPECTED_UPSTREAM
+```
+
+Then upload your change to AOSP gerrit.
+```shell
+repo upload --cbr .
+```
+
+Then you can switch back to your local `master` branch to apply the changes
+```shell
+git checkout <local_master_branch>
+git merge local_expected_upstream
+# Resolve any merge conflict
+git commit --amend # Amend the commit message and add the bug number you are working on
+repo upload .
+```
+
+### Add a java test from the upstream
+
+The process is similar to the above commands, but needs to run
+`ojluni_modify_expectation` with an `add` subcommand.
+
+For example, add a test for `String.isEmpty()` method:
+```shell
+ojluni_modify_expectation add jdk8u/jdk8u121-b13 java.lang.String.IsEmpty
+```
+Note: `java.lang.String.IsEmpty` is a test class in the upstream repository.
+
+# Submit your change in [AOSP gerrit](http://r.android.com/)
+```text
+----11.0.13-ga---------------- openjdk/jdk11u
+ \
+ A
+ \
+------------B-----C------------ expected_upstream
+ \
+--------------------D---E------ master
+```
+Here are the order of events / votes required to submit your CL on gerrit as of
+Nov 2021.
+1. `Presubmit-Verified +2` on all 5 CLs
+ * Due to [b/204973624](http://b/204973624), you may `Bypass-Presubmit +1`
+ on commit `A` and `B` if the presubmit fails.
+2. `Code-review +2` on all 5 CLs from an Android Core Library team member
+3. If needed, `API-review +1` on commit `E` from an Android API council member
+4. Click the submit button / `Autosubmit +1` on commit `B`, `C` and `E`
+ * Never submit commit `A` individually without submitting `B` together.
+ * Otherwise, gerrit will create another merge commit from `A` without
+ submitting `B`.
+ * Due a Gerrit bug, you can't submit the commit `C` before submitting `B`
+ first manually, even though `B` is the direct parent of `C`. So just
+ submit `B` yourself manually.
+ * If you can't submit the CL due a permission issue, ask an Android Core
+ Library member to submit.
+
+# Known bugs
+* `repo upload` may not succeed because gerrit returns error.
+ 1. Just try to run `repo upload` again!
+ * The initial upload takes a long time because it tries to sync with the
+ remote AOSP gerrit server. The second upload is much faster because
+ the `git` objects have been uploaded.
+ 2. `repo upload` returns TimeOutException, but the CL has been uploaded.
+ Just find your CL in http://r.android.com/. See http://b/202848945
+ 3. Try to upload the merge commits 1 by 1
+ ```shell
+ git rev-parse HEAD # a sha is printed and you will need it later
+ git reset HEAD~1 # reset to a earlier commit
+ repo upload --cbr . # try to upload it again
+ git reset <the sha printed above>
+ ```
+* After `ojluni_modify_expectation add` and `ojluni_refresh_files`, a `git commit -a`
+ would include more files than just EXPECTED_UPSTREAM, because `git`, e.g. `git status`,
+ isn't aware of changes in the working tree / in the file system. This can lead to
+ an error when checking out the branch that is based on master.
+ 1. Do a `git checkout --hard <initial commit before the add>`
+ 2. Rerun the `ojluni_modify_expectation add` and `ojluni_refresh_files`
+ 3. `git stash && git stash pop`
+ 4. Commit the updated EXPECTED_UPSTREAM and proceed
+
+# Report bugs
+* Report bugs if the git repository is corrupt!
+ * Sometimes, you can recover the repository by running `git reset aosp/expected_upstream`

+ first commit will override the file content in the second commit.

+"""
+Merges upstream files to ojluni. This is done by using git to perform a 3-way
+merge between the current (base) upstream version, ojluni and the new (target)
+upstream version. The 3-way merge is needed because ojluni sometimes contains
+some Android-specific changes from the upstream version.
+
+This tool is for libcore maintenance; if you're not maintaining libcore,
+you won't need it (and might not have access to some of the instructions
+below).
+
+The naming of the repositories (expected, ojluni, 7u40, 8u121-b13,
+9b113+, 9+181) is based on the directory name where corresponding
+snapshots are stored when following the instructions at
+http://go/libcore-o-verify
+
+This script tries to preserve Android changes to upstream code when moving to a
+newer version.
+
+All the work is made in a new directory which is initialized as a git
+repository. An example of the repository structure, where an update is made
+from version 9b113+ to 11+28, would be:
+
+ * 5593705 (HEAD -> main) Merge branch 'ojluni'
+ |\
+ | * 2effe03 (ojluni) Ojluni commit
+ * | 1bef5f3 Target commit (11+28)
+ |/
+ * 9ae2fbf Base commit (9b113+)
+
+The conflicts during the merge get resolved by git whenever possible. However,
+sometimes there are conflicts that need to be resolved manually. If that is the
+case, the script will terminate to allow for the resolving. Once the user has
+resolved the conflicts, they should rerun the script with the --continue
+option.
+
+Once the merge is complete, the script will copy the merged version back to
+ojluni within the $ANDROID_BUILD_TOP location.
+
+For the script to run correctly, it needs the following environment variables
+defined:
+ - OJLUNI_UPSTREAMS
+ - ANDROID_BUILD_TOP
+
+Possible uses:
+
+To merge in changes from a newer version of the upstream using a default
+working dir created in /tmp:
+ merge-from-upstream -f expected -t 11+28 java/util/concurrent
+
+To merge in changes from a newer version of the upstream using a custom
+working dir:
+ merge-from-upstream -f expected -t 11+28 \
+ -d $HOME/tmp/ojluni-merge java/util/concurrent
+
+To merge in changes for a single file:
+ merge-from-upstream -f 9b113+ -t 11+28 \
+ java/util/concurrent/atomic/AtomicInteger.java
+
+To merge in changes, using a custom folder, that require conflict resolution:
+ merge-from-upstream -f expected -t 11+28 \
+ -d $HOME/tmp/ojluni-merge \
+ java/util/concurrent
+ <manually resolve conflicts and add them to git staging>
+ merge-from-upstream --continue \
+ -d $HOME/tmp/ojluni-merge java/util/concurrent
