+# ADB Internals
+
+If you are new to adb source code, you should start by reading [OVERVIEW.TXT](OVERVIEW.TXT) which describes the three components of adb pipeline.
+
+This document is here to boost what can be achieved within a "window of naive interest". You will not find function or class documentation here but rather the "big picture" which should allow you to build a mental map to help navigate the code.
+
+## Three components of adb pipeline
+
+As outlined in the overview, this codebase generates three components (Client, Server (a.k.a Host), and Daemon (a.k.a adbd)). The central part is the Server which runs on the Host computer. On one side the Server exposes a "Smart Socket" to Clients such as adb or DDMLIB. On the other side, the Server continuously monitors for connecting Daemons (as USB devices or TCP emulator). Communication with a device is done with a Transport.
+
+```
++----------+              +------------------------+
+|   ADB    +----------+   |      ADB SERVER        |                   +----------+
+|  CLIENT  |          |   |                        |              (USB)|   ADBD   |

+                      |   |                        |                   +----------+

+                      |   |                        |                   +----------+

+|  DDMLIB  |          |   |                     Transport+--+          +----------+
+|  CLIENT  +----------+   |                        |        |  (TCP/IP)|   ADBD   |

+                                                                       +----------+
+```
+
+The Client and the Server are contained in the same executable and both run on the Host machine. Code sections specific to the Host is enclosed within `ADB_HOST` guard. adbd runs on the Android Device. Daemon specific code is enclosed in `!ADB_HOST` but also sometimes with-in `__ANDROID__` guard.
+
+
+## "SMART SOCKET" and TRANSPORT
+
+A smart socket is a simple TCP socket with a smart protocol built on top of it. This is what Clients connect onto from the Host side. The Client must always initiate communication via a human readable request but the response format varies. The smart protocol is documented in [SERVICES.TXT](SERVICES.TXT).
+
+On the other side, the Server communicate with a device via a Transport. adb initially targeted devices connecting over USB, which is restricted to a fixed number of data streams. Therefore, adb multiplexes multiple byte streams over a single pipe via Transport. When devices connecting over other mechanisms (e.g. emulators over TCP) were introduced, the existing transport protocol was maintained.
+
+## THREADING MODEL and FDEVENT system
+
+At the heart of both the Server and Daemon is a main thread running an fdevent loop, which is an platform-independent abstraction over poll/epoll/WSAPoll monitoring file descriptors events. Requests and services are usually server from the main thread but some service requests result in new threads being spawned.
+
+To allow for operations to run on the Main thread, fdevent features a RunQueue combined with an interrupt fd to force polling to return.
+
+```
++------------+    +-------------------------^
+|  RUNQUEUE  |    |                         |
++------------+    |  POLLING (Main thread)  |
+| Function<> |    |                         |
++------------+    |                         |
+| Function<> |    ^-^-------^-------^------^^
++------------+      |       |       |       |
+|    ...     |      |       |       |       |
++------------+      |       |       |       |
+|            |      |       |       |       |
+|============|      |       |       |       |
+|Interrupt fd+------+  +----+  +----+  +----+
++------------+         fd      Socket  Pipe
+```
+
+## ASOCKET, APACKET, and AMESSAGE
+
+The asocket, apacket, and amessage constructs exist only to wrap data while it transits on a Transport. An asocket handles a stream of apackets. An apacket consists in a amessage header featuring a command (`A_SYNC`, `A_OPEN`, `A_CLSE`, `A_WRTE`, `A_OKAY`, ...) followed by a payload (find more documentation in [protocol.txt](protocol.txt). There is no `A_READ` command because an asocket is unidirectional. To model a bi-directional stream, asocket have a peer which go in the opposite direction.
+
+An asocket features a buffer where the elemental unit is an apacket. Is traffic is inbound, the buffer stores apacket until they are consumed. If the traffic is oubound, the buffer store apackets until they are sent down the wire (with `A_WRTE` commands).
+
+```
++---------------------ASocket------------------------+
+ |                                                   |

+ | |                                               | |
+ | |            APacket     APacket     APacket    | |
+ | |          +--------+  +--------+  +--------+   | |
+ | |          |AMessage|  |AMessage|  |AMessage|   | |
+ | |          +--------+  +--------+  +--------+   | |
+ | |          |        |  |        |  |        |   | |
+ | |  .....   |        |  |        |  |        |   | |
+ | |          |  Data  |  |  Data  |  |  Data  |   | |
+ | |          |        |  |        |  |        |   | |
+ | |          |        |  |        |  |        |   | |
+ | |          +--------+  +--------+  +--------+   | |
+ | |                                               | |
+ | +-----------------------------------------------+ |
+ +---------------------------------------------------+
+```
+
+This system allows to multiplex data streams on an unique byte stream.  Without entering too much into details, the amessage fields arg1 and arg2 are used alike in the TCP protocol where local and remote ports identify an unique stream. Note that unlike TCP which feature an "unacknowledged-send window", an apacket is sent only after the previous one has been confirmed to be received.
+
+The two types of asocket (Remote and Local) differentiate between outbound and inbound traffic.

+ *     c: Zero op

+ *    for which one of the 3 operations have to be applied.
+ *    This represents the old_chunk in the kernel COW format
+ * 4: We need to assign new_chunk for a corresponding old_chunk
+ * 5: The algorithm is similar to how kernel assigns chunk number
+ *    while creating exceptions.
+ * 6: Use a monotonically increasing chunk number to assign the
+ *    new_chunk
+ * 7: Each chunk-id represents either a: Metadata page or b: Data page
+ * 8: Chunk-id representing a data page is stored in a vector. Index is the
+ *    chunk-id and value is the pointer to the CowOperation
+ * 9: Chunk-id representing a metadata page is converted into a vector
+ *    index. We store this in vector as kernel requests metadata during
+ *    two stage:
+ *       a: When initial dm-snapshot device is created, kernel requests
+ *          all the metadata and stores it in its internal data-structures.
+ *       b: During merge, kernel once again requests the same metadata
+ *          once-again.
+ *    In both these cases, a quick lookup based on chunk-id is done.
+ * 10: When chunk number is incremented, we need to make sure that
+ *    if the chunk is representing a metadata page and skip.
+ * 11: Each 4k page will contain 256 disk exceptions. We call this
+ *    exceptions_per_area_
+ * 12: Kernel will stop issuing metadata IO request when new-chunk ID is 0.

+ * 4: Initialize the Second stage daemon passing the information from the
+ * vector. This will bind the daemon with dm-user misc device and will be ready
+ * to serve the IO. Up until this point, first stage daemon is still active.
+ * However, client library will mark the first stage daemon as passive and hence
+ * all the control message from hereon will be sent to active second stage
+ * daemon.
+ *
+ * 5: Create new dm-snapshot table. This is done by libsnapshot. When new table
+ * is created, kernel will issue metadata read once again which will be served
+ * by second stage daemon. However, any active IO will still be served by first
+ * stage daemon.
+ *
+ * 6: Swap the snapshot table atomically - This is done by libsnapshot. Once
+ * the swapping is done, all the IO will be served by second stage daemon.
+ *
+ * 7: Stop the first stage daemon. After this point second stage daemon is
+ * completely active to serve the IO and merging process.

-
-      "You" (or "Your") shall mean an individual or Legal Entity
-      exercising permissions granted by this License.
-
-      "Source" form shall mean the preferred form for making modifications,
-      including but not limited to software source code, documentation
-      source, and configuration files.
-
-      "Object" form shall mean any form resulting from mechanical
-      transformation or translation of a Source form, including but
-      not limited to compiled object code, generated documentation,
-      and conversions to other media types.
-
-      "Work" shall mean the work of authorship, whether in Source or
-      Object form, made available under the License, as indicated by a
-      copyright notice that is included in or attached to the work
-      (an example is provided in the Appendix below).
-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain
-      separable from, or merely link (or bind by name) to the interfaces of,
-      the Work and Derivative Works thereof.
-
-      "Contribution" shall mean any work of authorship, including
-      the original version of the Work and any modifications or additions
-      to that Work or Derivative Works thereof, that is intentionally
-      submitted to Licensor for inclusion in the Work by the copyright owner
-      or by an individual or Legal Entity authorized to submit on behalf of
-      the copyright owner. For the purposes of this definition, "submitted"
-      means any form of electronic, verbal, or written communication sent
-      to the Licensor or its representatives, including but not limited to
-      communication on electronic mailing lists, source code control systems,
-      and issue tracking systems that are managed by, or on behalf of, the
-      Licensor for the purpose of discussing and improving the Work, but
-      excluding communication that is conspicuously marked or otherwise
-      designated in writing by the copyright owner as "Not a Contribution."
-
-      "Contributor" shall mean Licensor and any individual or Legal Entity
-      on behalf of whom a Contribution has been received by Licensor and
-      subsequently incorporated within the Work.
-
-   2. Grant of Copyright License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the
-      Work and such Derivative Works in Source or Object form.
-
-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,
-      where such license applies only to those patent claims licensable
-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
-
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

-Description
------------
-
-liblog represents an interface to the volatile Android Logging system for NDK (Native) applications
-and libraries.  Interfaces for either writing or reading logs.  The log buffers are divided up in
-Main, System, Radio and Events sub-logs.
-
-The logging interfaces are a series of macros, all of which can be overridden individually in order
-to control the verbosity of the application or library.  `[ASR]LOG[VDIWE]` calls are used to log to
-BAsic, System or Radio sub-logs in either the Verbose, Debug, Info, Warning or Error priorities.
-`[ASR]LOG[VDIWE]_IF` calls are used to perform thus based on a condition being true.
-`IF_ALOG[VDIWE]` calls are true if the current `LOG_TAG` is enabled at the specified priority.
-`LOG_ALWAYS_FATAL` is used to `ALOG` a message, then kill the process.  `LOG_FATAL` call is a
-variant of `LOG_ALWAYS_FATAL`, only enabled in engineering, and not release builds.  `ALOG_ASSERT`
-is used to `ALOG` a message if the condition is false; the condition is part of the logged message.
-`LOG_EVENT_(INT|LONG)` is used to drop binary content into the Events sub-log.
-
-The log reading interfaces permit opening the logs either singly or multiply, retrieving a log entry
-at a time in time sorted order, optionally limited to a specific pid and tail of the log(s) and
-finally a call closing the logs.  A single log can be opened with `android_logger_list_open()`; or
-multiple logs can be opened with `android_logger_list_alloc()`, calling in turn the
-`android_logger_open()` for each log id.  Each entry can be retrieved with
-`android_logger_list_read()`.  The log(s) can be closed with `android_logger_list_free()`.
-`ANDROID_LOG_NONBLOCK` mode will report when the log reading is done with an `EAGAIN` error return
-code, otherwise the `android_logger_list_read()` call will block for new entries.
-
-The `ANDROID_LOG_WRAP` mode flag to the `android_logger_list_alloc_time()` signals logd to quiesce
-the reader until the buffer is about to prune at the start time then proceed to dumping content.
-
-The `ANDROID_LOG_PSTORE` mode flag to the `android_logger_open()` is used to switch from the active
-logs to the persistent logs from before the last reboot.
-
-The value returned by `android_logger_open()` can be used as a parameter to the
-`android_logger_clear()` function to empty the sub-log.
-
-The value returned by `android_logger_open()` can be used as a parameter to the
-`android_logger_get_log_(size|readable_size|version)` to retrieve the sub-log maximum size, readable
-size and log buffer format protocol version respectively.  `android_logger_get_id()` returns the id
-that was used when opening the sub-log.
-
-Errors
-------
-
-If messages fail, a negative error code will be returned to the caller.
-
-The `-ENOTCONN` return code indicates that the logger daemon is stopped.
-
-The `-EBADF` return code indicates that the log access point can not be opened, or the log buffer id
-is out of range.
-
-For the `-EAGAIN` return code, this means that the logging message was temporarily backed-up either
-because of Denial Of Service (DOS) logging pressure from some chatty application or service in the
-Android system, or if too small of a value is set in /proc/sys/net/unix/max_dgram_qlen.  To aid in
-diagnosing the occurence of this, a binary event from liblog will be sent to the log daemon once a
-new message can get through indicating how many messages were dropped as a result.  Please take
-action to resolve the structural problems at the source.
-
-It is generally not advised for the caller to retry the `-EAGAIN` return code as this will only make
-the problem(s) worse and cause your application to temporarily drop to the logger daemon priority,
-BATCH scheduling policy and background task cgroup. If you require a group of messages to be passed
-atomically, merge them into one message with embedded newlines to the maximum length
-`LOGGER_ENTRY_MAX_PAYLOAD`.
-
-Other return codes from writing operation can be returned.  Since the library retries on `EINTR`,
-`-EINTR` should never be returned.

-# liblog -> logd
-
-The data that liblog sends to logd is represented below.
-
-    struct {
-        android_log_header_t header;
-        union {
-           struct {
-                char     prio;
-                char     tag[...];
-                char     message[...];
-            } string;
-            struct {
-                android_event_header_t event_header;
-                android_event_*_t      payload[...];
-            } binary;
-        };
-    };
-
-where the embedded structs are defined as:
-
-    struct android_log_header_t {
-        uint8_t id;
-        uint16_t tid;
-        log_time realtime;
-    };
-
-    struct log_time {
-        uint32_t tv_sec = 0;
-        uint32_t tv_nsec = 0;
-    }
-
-    struct android_event_header_t {
-        int32_t tag;
-    };
-
-    struct android_event_list_t {
-        int8_t type;  // EVENT_TYPE_LIST
-        int8_t element_count;
-    };
-
-    struct android_event_float_t {
-        int8_t type;  // EVENT_TYPE_FLOAT
-        float data;
-    };
-
-    struct android_event_int_t {
-        int8_t type;   // EVENT_TYPE_INT
-        int32_t data;
-    } android_event_int_t;
-
-    struct android_event_long_t {
-        int8_t type;   // EVENT_TYPE_LONG
-        int64_t data;
-    };
-
-    struct android_event_string_t {
-        int8_t type;     // EVENT_TYPE_STRING;
-        int32_t length;
-        char data[];
-    };
-
-The payload, excluding the header, has a max size of LOGGER_ENTRY_MAX_PAYLOAD.
-
-## header
-
-The header is added immediately before sending the log message to logd.
-
-## `string` payload
-
-The `string` part of the union is for normal buffers (main, system, radio, etc) and consists of a
-single character priority, followed by a variable length null terminated string for the tag, and
-finally a variable length null terminated string for the message.
-
-This payload is used for the `__android_log_buf_write()` family of functions.
-
-## `binary` payload
-
-The `binary` part of the union is for binary buffers (events, security, etc) and consists of an
-android_event_header_t struct followed by a variable number of android_event_*_t
-(android_event_list_t, android_event_int_t, etc) structs.
-
-If multiple android_event_*_t elements are present, then they must be in a list and the first
-element in payload must be an android_event_list_t.
-
-This payload is used for the `__android_log_bwrite()` family of functions. It is additionally used
-for `android_log_write_list()` and the related functions that manipulate event lists.
-
-# logd -> liblog
-
-logd sends a `logger_entry` struct to liblog followed by the payload. The payload is identical to
-the payloads defined above. The max size of the entire message from logd is LOGGER_ENTRY_MAX_LEN.

- * Each log message must have

- *   - some text
- *
- * The tag normally corresponds to the component that emits the log message,

- *
- * Please use logging in moderation:
- *
- *  - Sending log messages eats CPU and slow down your application and the
- *    system.
- *
- *  - The circular log buffer is pretty small, so sending many messages
- *    will hide other important log messages.
- *
- *  - In release builds, only send log messages to account for exceptional

-I learn in this letter that Don Peter of Arragon\n\
-comes this night to Messina\n\
-MESSENGER\n\
-He is very near by this: he was not three leagues off\n\
-when I left him\n\
-LEONATO\n\
-How many gentlemen have you lost in this action?\n\
-MESSENGER\n\
-But few of any sort, and none of name\n\
-LEONATO\n\
-A victory is twice itself when the achiever brings\n\
-home full numbers. I find here that Don Peter hath\n\
-bestowed much honour on a young Florentine called Claudio\n\
-MESSENGER\n\
-Much deserved on his part and equally remembered by\n\
-Don Pedro: he hath borne himself beyond the\n\
-promise of his age, doing, in the figure of a lamb,\n\
-the feats of a lion: he hath indeed better\n\
-bettered expectation than you must expect of me to\n\
-tell you how\n\
-LEONATO\n\
-He hath an uncle here in Messina will be very much\n\
-glad of it.\n\
-MESSENGER\n\
-I have already delivered him letters, and there\n\
-appears much joy in him; even so much that joy could\n\
-not show itself modest enough without a badge of\n\
-bitterness.\n\
-LEONATO\n\
-Did he break out into tears?\n\
-MESSENGER\n\
-In great measure.\n\
-LEONATO\n\
-A kind overflow of kindness: there are no faces\n\
-truer than those that are so washed. How much\n\
-better is it to weep at joy than to joy at weeping!\n\
-BEATRICE\n\
-I pray you, is Signior Mountanto returned from the\n\
-wars or no?\n\
-MESSENGER\n\
-I know none of that name, lady: there was none such\n\
-in the army of any sort.\n\
-LEONATO\n\
-What is he that you ask for, niece?\n\
-HERO\n\
-My cousin means Signior Benedick of Padua.\n\
-MESSENGER\n\
-O, he's returned; and as pleasant as ever he was.\n\
-BEATRICE\n\
-He set up his bills here in Messina and challenged\n\
-Cupid at the flight; and my uncle's fool, reading\n\
-the challenge, subscribed for Cupid, and challenged\n\
-him at the bird-bolt. I pray you, how many hath he\n\
-killed and eaten in these wars? But how many hath\n\
-he killed? for indeed I promised to eat all of his killing.\n\
-LEONATO\n\
-Faith, niece, you tax Signior Benedick too much;\n\
-but he'll be meet with you, I doubt it not.\n\
-MESSENGER\n\
-He hath done good service, lady, in these wars.\n\
-BEATRICE\n\
-You had musty victual, and he hath holp to eat it:\n\
-he is a very valiant trencherman; he hath an\n\
-excellent stomach.\n\
-MESSENGER\n\
-And a good soldier too, lady.\n\
-BEATRICE\n\
-And a good soldier to a lady: but what is he to a lord?\n\
-MESSENGER\n\
-A lord to a lord, a man to a man; stuffed with all\n\
-honourable virtues.\n\
-BEATRICE\n\
-It is so, indeed; he is no less than a stuffed man:\n\
-but for the stuffing,--well, we are all mortal.\n\
-LEONATO\n\
-You must not, sir, mistake my niece. There is a\n\
-kind of merry war betwixt Signior Benedick and her:\n\
-they never meet but there's a skirmish of wit\n\
-between them.\n\
-BEATRICE\n\
-Alas! he gets nothing by that. In our last\n\
-conflict four of his five wits went halting off, and\n\
-now is the whole man governed with one: so that if\n\
-he have wit enough to keep himself warm, let him\n\
-bear it for a difference between himself and his\n\
-horse; for it is all the wealth that he hath left,\n\
-to be known a reasonable creature. Who is his\n\
-companion now? He hath every month a new sworn brother.\n\
-MESSENGER\n\
-Is't possible?\n\
-BEATRICE\n\
-Very easily possible: he wears his faith but as\n\
-the fashion of his hat; it ever changes with the\n\
-next block.\n\
-MESSENGER\n\
-I see, lady, the gentleman is not in your books.\n\
-BEATRICE\n\
-No; an he were, I would burn my study. But, I pray\n\
-you, who is his companion? Is there no young\n\
-squarer now that will make a voyage with him to the devil?\n\
-MESSENGER\n\
-He is most in the company of the right noble Claudio.\n\
-BEATRICE\n\
-O Lord, he will hang upon him like a disease: he\n\
-is sooner caught than the pestilence, and the taker\n\
-runs presently mad. God help the noble Claudio! if\n\
-he have caught the Benedick, it will cost him a\n\
-thousand pound ere a' be cured.\n\
-MESSENGER\n\
-I will hold friends with you, lady.\n\
-BEATRICE\n\
-Do, good friend.\n\
-LEONATO\n\
-You will never run mad, niece.\n\
-BEATRICE\n\
-No, not till a hot January.\n\
-MESSENGER\n\
-Don Pedro is approached.\n\
-Enter DON PEDRO, DON JOHN, CLAUDIO, BENEDICK, and BALTHASAR\n\
-\n\
-DON PEDRO\n\
-Good Signior Leonato, you are come to meet your\n\
-trouble: the fashion of the world is to avoid\n\
-cost, and you encounter it\n\
-LEONATO\n\
-Never came trouble to my house in the likeness of your grace,\n\
-for trouble being gone, comfort should remain, but\n\
-when you depart from me, sorrow abides and happiness\n\
-takes his leave.";

-      source, and configuration files.
-
-      "Object" form shall mean any form resulting from mechanical
-      transformation or translation of a Source form, including but
-      not limited to compiled object code, generated documentation,
-      and conversions to other media types.
-
-      "Work" shall mean the work of authorship, whether in Source or
-      Object form, made available under the License, as indicated by a
-      copyright notice that is included in or attached to the work
-      (an example is provided in the Appendix below).
-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain
-      separable from, or merely link (or bind by name) to the interfaces of,
-      the Work and Derivative Works thereof.
-
-      "Contribution" shall mean any work of authorship, including
-      the original version of the Work and any modifications or additions
-      to that Work or Derivative Works thereof, that is intentionally
-      submitted to Licensor for inclusion in the Work by the copyright owner
-      or by an individual or Legal Entity authorized to submit on behalf of
-      the copyright owner. For the purposes of this definition, "submitted"
-      means any form of electronic, verbal, or written communication sent
-      to the Licensor or its representatives, including but not limited to
-      communication on electronic mailing lists, source code control systems,
-      and issue tracking systems that are managed by, or on behalf of, the
-      Licensor for the purpose of discussing and improving the Work, but
-      excluding communication that is conspicuously marked or otherwise
-      designated in writing by the copyright owner as "Not a Contribution."
-
-      "Contributor" shall mean Licensor and any individual or Legal Entity
-      on behalf of whom a Contribution has been received by Licensor and
-      subsequently incorporated within the Work.
-
-   2. Grant of Copyright License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the
-      Work and such Derivative Works in Source or Object form.
-
-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,
-      where such license applies only to those patent claims licensable
-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
-
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

- * .macro pixel
- *
- *  This macro alpha blends RGB565 original pixel located in either
- *  top or bottom 16 bits of DREG register with SRC 32 bit pixel value
- *  and writes the result to FB register
- *
- * \DREG is a 32-bit register containing *two* original destination RGB565
- *       pixels, with the even one in the low-16 bits, and the odd one in the
- *       high 16 bits.
- *
- * \SRC is a 32-bit 0xAABBGGRR pixel value, with pre-multiplied colors.
- *
- * \FB is a target register that will contain the blended pixel values.
- *
- * \ODD is either 0 or 1 and indicates if we're blending the lower or
- *      upper 16-bit pixels in DREG into FB
- *
- *
- * clobbered: w6, w7, w15, w16, w17

-** --------------------------------------------
-** Support for Arm64 in GGLAssembler JIT
-** --------------------------------------------
-**
-** Approach
-** - GGLAssembler and associated files are largely un-changed.
-** - A translator class maps ArmAssemblerInterface calls to
-**   generate Arm64 instructions.
-**
-** ----------------------
-** ArmToArm64Assembler
-** ----------------------
-**
-** - Subclassed from ArmAssemblerInterface
-**
-** - Translates each ArmAssemblerInterface call to generate
-**   one or more Arm64 instructions  as necessary.
-**
-** - Does not implement ArmAssemblerInterface portions unused by GGLAssembler
-**   It calls NOT_IMPLEMENTED() for such cases, which in turn logs
-**    a fatal message.
-**
-** - Uses A64_.. series of functions to generate instruction machine code
-**   for Arm64 instructions. These functions also log the instruction
-**   to LOG, if ARM64_ASM_DEBUG define is set to 1
-**
-** - Dumps machine code and eqvt assembly if "debug.pf.disasm" option is set
-**   It uses arm64_disassemble to perform disassembly
-**
-** - Uses register 13 (SP in ARM), 15 (PC in ARM), 16, 17 for storing
-**   intermediate results. GGLAssembler does not use SP and PC as these
-**   registers are marked as reserved. The temporary registers are not
-**   saved/restored on stack as these are caller-saved registers in Arm64
-**
-** - Uses CSEL instruction to support conditional execution. The result is
-**   stored in a temporary register and then copied to the target register
-**   if the condition is true.
-**
-** - In the case of conditional data transfer instructions, conditional
-**   branch is used to skip over instruction, if the condition is false
-**
-** - Wherever possible, immediate values are transferred to temporary
-**   register prior to processing. This simplifies overall implementation
-**   as instructions requiring immediate values are converted to
-**   move immediate instructions followed by register-register instruction.
-**
-** --------------------------------------------
-** ArmToArm64Assembler unit test bench
-** --------------------------------------------
-**
-** - Tests ArmToArm64Assembler interface for all the possible
-**   ways in which GGLAssembler uses ArmAssemblerInterface interface.
-**
-** - Uses test jacket (written in assembly) to set the registers,
-**   condition flags prior to calling generated instruction. It also
-**   copies registers and flags at the end of execution. Caller then
-**   checks if generated code performed correct operation based on
-**   output registers and flags.
-**
-** - Broadly contains three type of tests, (i) data operation tests
-**   (ii) data transfer tests and (iii) LDM/STM tests.
-**
-** ----------------------
-** Arm64 disassembler
-** ----------------------
-** - This disassembler disassembles only those machine codes which can be
-**   generated by ArmToArm64Assembler. It has a unit testbench which
-**   tests all the instructions supported by the disassembler.
-**
-** ------------------------------------------------------------------
-** ARMAssembler/ARMAssemblerInterface/ARMAssemblerProxy changes
-** ------------------------------------------------------------------
-**
-** - In existing code, addresses were being handled as 32 bit values at
-**   certain places.
-**
-** - Added a new set of functions for address load/store/manipulation.
-**   These are ADDR_LDR, ADDR_STR, ADDR_ADD, ADDR_SUB and they map to
-**   default 32 bit implementations in ARMAssemblerInterface.
-**
-** - ArmToArm64Assembler maps these functions to appropriate 64 bit
-**   functions.
-**
-** ----------------------
-** GGLAssembler changes
-** ----------------------
-** - Since ArmToArm64Assembler can generate 4 Arm64 instructions for
-**   each call in worst case, the memory required is set to 4 times
-**   ARM memory
-**
-** - Address load/store/manipulation were changed to use new functions
-**   added in the ARMAssemblerInterface.

-/* MIPS assembler and ARM->MIPS assembly translator
-**
-** The approach is to leave the GGLAssembler and associated files largely
-** un-changed, still utilizing all Arm instruction generation. Via the
-** ArmToMipsAssembler (subclassed from ArmAssemblerInterface) each Arm
-** instruction is translated to one or more Mips instructions as necessary. This
-** is clearly less efficient than a direct implementation within the
-** GGLAssembler, but is far cleaner, more maintainable, and has yielded very
-** significant performance gains on Mips compared to the generic pixel pipeline.
-**
-**
-** GGLAssembler changes
-**
-** - The register allocator has been modified to re-map Arm registers 0-15 to mips
-** registers 2-17. Mips register 0 cannot be used as general-purpose register,
-** and register 1 has traditional uses as a short-term temporary.
-**
-** - Added some early bailouts for OUT_OF_REGISTERS in texturing.cpp and
-** GGLAssembler.cpp, since this is not fatal, and can be retried at lower
-** optimization level.
-**
-**
-** ARMAssembler and ARMAssemblerInterface changes
-**
-** Refactored ARM address-mode static functions (imm(), reg_imm(), imm12_pre(), etc.)
-** to virtual, so they can be overridden in MIPSAssembler. The implementation of these
-** functions on ARM is moved from ARMAssemblerInterface.cpp to ARMAssembler.cpp, and
-** is unchanged from the original. (This required duplicating 2 of these as static
-** functions in ARMAssemblerInterface.cpp so they could be used as static initializers).

-**
-** To that end, there is no need for floating point, or priviledged
-** instructions. This all runs in user space, no float.
-**
-** The syntax makes no attempt to be as complete as the assember, with
-** synthetic instructions, and automatic recognition of immedate operands
-** (use the immediate form of the instruction), etc.
-**
-** We start with mips32r1, and may add r2 and dsp extensions if cpu
-** supports. Decision will be made at compile time, based on gcc
-** options. (makes sense since android will be built for a a specific

- *     system/core/include/private/pixelflinger/ggl_context.h
- *
- * Especially the lines defining and using GGL_RESERVE_NEEDS
- *
- * Quick reminders:
- *   - the last nibble of the first value is the destination buffer format.
- *   - the last nibble of the third value is the source texture format
- *   - formats: 4=rgb565 1=abgr8888 2=xbgr8888
- *
- * In the descriptions below:
- *
- *   SRC      means we copy the source pixels to the destination
- *
- *   SRC_OVER means we blend the source pixels to the destination
- *            with dstFactor = 1-srcA, srcFactor=1  (premultiplied source).
- *            This mode is otherwise called 'blend'.
- *
- *   SRCA_OVER means we blend the source pixels to the destination
- *             with dstFactor=srcA*(1-srcA) srcFactor=srcA (non-premul source).
- *             This mode is otherwise called 'blend_srca'
- *
- *   clamp    means we fetch source pixels from a texture with u/v clamping
- *
- *   mod      means the source pixels are modulated (multiplied) by the
- *            a/r/g/b of the current context's color. Typically used for
- *            fade-in / fade-out.
- *
- *   dither   means we dither 32 bit values to 16 bits

-
-      "Object" form shall mean any form resulting from mechanical
-      transformation or translation of a Source form, including but
-      not limited to compiled object code, generated documentation,
-      and conversions to other media types.
-
-      "Work" shall mean the work of authorship, whether in Source or
-      Object form, made available under the License, as indicated by a
-      copyright notice that is included in or attached to the work
-      (an example is provided in the Appendix below).
-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain

-      the Work and Derivative Works thereof.
-
-      "Contribution" shall mean any work of authorship, including
-      the original version of the Work and any modifications or additions
-      to that Work or Derivative Works thereof, that is intentionally

-      designated in writing by the copyright owner as "Not a Contribution."
-
-      "Contributor" shall mean Licensor and any individual or Legal Entity
-      on behalf of whom a Contribution has been received by Licensor and
-      subsequently incorporated within the Work.
-
-   2. Grant of Copyright License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the
-      Work and such Derivative Works in Source or Object form.
-
-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,
-      where such license applies only to those patent claims licensable
-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
-
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-

-# The entries in this file map a sparse set of log tag numbers to tag names.
-# This is installed on the device, in /system/etc, and parsed by logcat.
-#
-# Tag numbers are decimal integers, from 0 to 2^31.  (Let's leave the
-# negative values alone for now.)
-#
-# Tag names are one or more ASCII letters and numbers or underscores, i.e.
-# "[A-Z][a-z][0-9]_".  Do not include spaces or punctuation (the former
-# impacts log readability, the latter makes regex searches more annoying).
-#
-# Tag numbers and names are separated by whitespace.  Blank lines and lines
-# starting with '#' are ignored.
-#
-# Optionally, after the tag names can be put a description for the value(s)
-# of the tag. Description are in the format
-#    (<name>|data type[|data unit])
-# Multiple values are separated by commas.
-#
-# The data type is a number from the following values:
-# 1: int
-# 2: long
-# 3: string
-# 4: list
-# 5: float
-#
-# The data unit is a number taken from the following list:

-  -v, --format=<format>       Sets log print format verb and adverbs, where <format> is one of:
-                                brief help long process raw tag thread threadtime time
-                              Modifying adverbs can be added:
-                                color descriptive epoch monotonic printable uid usec UTC year zone
-                              Multiple -v parameters or comma separated list of format and format
-                              modifiers are allowed.
-  -D, --dividers              Print dividers between each log buffer.
-  -B, --binary                Output the log in binary.
-
-Outfile files:
-  -f, --file=<file>           Log to file instead of stdout.
-  -r, --rotate-kbytes=<n>     Rotate log every <n> kbytes. Requires -f option.
-  -n, --rotate-count=<count>  Sets max number of rotated logs to <count>, default 4.
-  --id=<id>                   If the signature <id> for logging to file changes, then clear the
-                              associated files and continue.
-
-Logd control:
- These options send a control message to the logd daemon on device, print its return message if
- applicable, then exit. They are incompatible with -L, as these attributes do not apply to pstore.
-  -g, --buffer-size           Get the size of the ring buffers within logd.
-  -G, --buffer-size=<size>    Set size of a ring buffer in logd. May suffix with K or M.
-                              This can individually control each buffer's size with -b.
-  -S, --statistics            Output statistics.
-                              --pid can be used to provide pid specific stats.
-  -p, --prune                 Print prune rules. Each rule is specified as UID, UID/PID or /PID. A
-                              '~' prefix indicates that elements matching the rule should be pruned
-                              with higher priority otherwise they're pruned with lower priority. All
-                              other pruning activity is oldest first. Special case ~! represents an
-                              automatic pruning for the noisiest UID as determined by the current
-                              statistics.  Special case ~1000/! represents pruning of the worst PID
-                              within AID_SYSTEM when AID_SYSTEM is the noisiest UID.
-  -P, --prune='<list> ...'    Set prune rules, using same format as listed above. Must be quoted.
-
-Filtering:
-  -s                          Set default filter to silent. Equivalent to filterspec '*:S'
-  -e, --regex=<expr>          Only print lines where the log message matches <expr> where <expr> is
-                              an ECMAScript regular expression.
-  -m, --max-count=<count>     Quit after printing <count> lines. This is meant to be paired with
-                              --regex, but will work on its own.
-  --print                     This option is only applicable when --regex is set and only useful if
-                              --max-count is also provided.
-                              With --print, logcat will print all messages even if they do not
-                              match the regex. Logcat will quit after printing the max-count number
-                              of lines that match the regex.
-  -t <count>                  Print only the most recent <count> lines (implies -d).
-  -t '<time>'                 Print the lines since specified time (implies -d).
-  -T <count>                  Print only the most recent <count> lines (does not imply -d).
-  -T '<time>'                 Print the lines since specified time (not imply -d).
-                              count is pure numerical, time is 'MM-DD hh:mm:ss.mmm...'
-                              'YYYY-MM-DD hh:mm:ss.mmm...' or 'sssss.mmm...' format.
-  --uid=<uids>                Only display log messages from UIDs present in the comma separate list
-                              <uids>. No name look-up is performed, so UIDs must be provided as
-                              numeric values. This option is only useful for the 'root', 'log', and
-                              'system' users since only those users can view logs from other users.

-// prune "pruneRows" of type "id" from the buffer.
-//
-// This garbage collection task is used to expire log entries. It is called to
-// remove all logs (clear), all UID logs (unprivileged clear), or every
-// 256 or 10% of the total logs (whichever is less) to prune the logs.
-//
-// First there is a prep phase where we discover the reader region lock that
-// acts as a backstop to any pruning activity to stop there and go no further.
-//
-// There are three major pruning loops that follow. All expire from the oldest
-// entries. Since there are multiple log buffers, the Android logging facility
-// will appear to drop entries 'in the middle' when looking at multiple log
-// sources and buffers. This effect is slightly more prominent when we prune
-// the worst offender by logging source. Thus the logs slowly loose content
-// and value as you move back in time. This is preferred since chatty sources
-// invariably move the logs value down faster as less chatty sources would be
-// expired in the noise.
-//
-// The first pass prunes elements that match 3 possible rules:
-// 1) A high priority prune rule, for example ~100/20, which indicates elements from UID 100 and PID
-//    20 should be pruned in this first pass.
-// 2) The default chatty pruning rule, ~!.  This rule sums the total size spent on log messages for
-//    each UID this log buffer.  If the highest sum consumes more than 12.5% of the log buffer, then
-//    these elements from that UID are pruned.
-// 3) The default AID_SYSTEM pruning rule, ~1000/!.  This rule is a special case to 2), if
-//    AID_SYSTEM is the top consumer of the log buffer, then this rule sums the total size spent on
-//    log messages for each PID in AID_SYSTEM in this log buffer and prunes elements from the PID
-//    with the highest sum.
-// This pass reevaluates the sums for rules 2) and 3) for every log message pruned. It creates
-// 'chatty' entries for the elements that it prunes and merges related chatty entries together. It
-// completes when one of three conditions have been met:
-// 1) The requested element count has been pruned.
-// 2) There are no elements that match any of these rules.
-// 3) A reader is referencing the oldest element that would match these rules.
-//
-// The second pass prunes elements starting from the beginning of the log.  It skips elements that
-// match any low priority prune rules.  It completes when one of three conditions have been met:
-// 1) The requested element count has been pruned.
-// 2) All elements except those mwatching low priority prune rules have been pruned.
-// 3) A reader is referencing the oldest element that would match these rules.
-//
-// The final pass only happens if there are any low priority prune rules and if the first two passes
-// were unable to prune the requested number of elements.  It prunes elements all starting from the
-// beginning of the log, regardless of if they match any low priority prune rules.
-//
-// If the requested number of logs was unable to be pruned, KickReader() is called to mitigate the
-// situation before the next call to Prune() and the function returns false.  Otherwise, if the
-// requested number of logs or all logs present in the buffer are pruned, in the case of Clear(),
-// it returns true.

-Auditd Daemon
-
-The audit daemon is a simplified version of its desktop
-counterpart designed to gather the audit logs from the
-audit kernel subsystem. The audit subsystem of the kernel
-includes Linux Security Modules (LSM) messages as well.
-
-To enable the audit subsystem, you must add this to your
-kernel config:
-CONFIG_AUDIT=y
-
-To enable a LSM, you must consult that LSM's documentation, the
-example below is for SELinux:
-CONFIG_SECURITY_SELINUX=y
-
-This does not include possible dependencies that may need to be
-satisfied for that particular LSM.

-# Log Compression instead of Chatty in Android S
-
-## The problem
-
-* Log buffer space is precious, but suffers from the tragedy of the commons
-* Log spam fills the buffers making them less useful in logcat/bugreports
-* “Spam” is often in the eye of the beholder: which messages are important depends on what you’re trying to debug
-
-## The idea
-
-* Chatty isn’t helping as much as we’d hoped, and is surprisingly expensive
-* Compress logs to make more efficient use of the buffer
-* Address the root cause of log spam at its source:
-    * Do not hide log spam at runtime, which de-incentivize fixes
-    * Add presubmit coverage similar to SELinux violations to keep log spam down
-
----
-
-## Chatty in Theory
-
-* Delete messages classified as spam to extend the range of logs from other sources
-* “Spam” defined as:
-    * Logs from UIDs whose logs consume over 12.5% of a log buffer
-    * Back-to-back exact duplicate messages
-
-## Chatty in Practice
-
-* Developer confusion about missing and de-duplicated logs
-* Lowered incentive to fix the root cause of bad logging behavior
-* High CPU overhead
-* Memory usage greatly exceeds configured buffer size
-* Only marginal increase in log range
-
----
-
-## Log Compression in Theory
-
-* Store many more logs in the same log buffer size => better for diagnosis
-* Memory usage stays below configured log size => better system health
-* No gaps in logs, no de-duplicated logs => no developer confusion
-* No hiding bad behavior => increased accountability/incentive to fix root causes
-
-## Log Compression Preliminary Results
-
-* Captured 2, 5 day periods of full time personal usage of Pixel 4 and replayed the logs offline
-* Compression vs Chatty:
-    * **3.5x more log messages on average**
-    * **50% less CPU usage**
-    * **50% less memory usage**
-
----
-
-## Log Messages in 1MB
-
-* The number of log messages still available in logcat after ‘Message Count’ messages have been logged to a 1MB log buffer
-* Note: ‘Simple’ is the Chatty code without log spam detection and without de-duplication.
-
-![Total Log Count](doc_images/total_log_count.png)
-
----
-
-## CPU Time
-
-* Total CPU time on ARM64 (Walleye) and 32bit x86 (Cuttlefish)
-* X axis represents different log buffer size configurations.
-    * Chatty uses significantly more CPU time at 1MB (the default Pixel configuration)
-    * Chatty scales poorly with increased log buffer sizes
-* Note: “simple” isn’t “compression without actually compressing”, it’s “chatty without doing the chatty elimination”, which is why “simple” is more expensive than “compression” on walleye.
-
-![CPU Time Walleye](doc_images/cpu_walleye.png)
-![CPU Time Cuttlefish](doc_images/cpu_cuttlefish.png)
-
----
-
-## Memory Usage
-
-* The memory used by ‘Message Count’ messages, on both Walleye and Cuttlefish
-* Note: Chatty does not consider the metadata (UID, PID, timestamp, etc) in its calculation of log buffer size, so a 1MB log buffer will consume more than 1MB.  Note that there are 8 log buffers, 5 of which are typically filled.

-logd can record and replay log messages for offline analysis.
-
-Recording Messages
-------------------
-
-logd has a `RecordingLogBuffer` buffer that records messages to /data/misc/logd/recorded-messages.
-It stores messages in memory until that file is accessible, in order to capture all messages since
-the beginning of boot.  It is only meant for logging developers to use and must be manually enabled
-in by adding `RecordingLogBuffer.cpp` to `Android.bp` and setting
-`log_buffer = new SimpleLogBuffer(&reader_list, &log_tags, &log_statistics);` in `main.cpp`.
-
-Recording messages may delay the Log() function from completing and it is highly recommended to make
-the logd socket in `liblog` blocking, by removing `SOCK_NONBLOCK` from the `socket()` call in
-`liblog/logd_writer.cpp`.
-
-Replaying Messages
-------------------
-
-Recorded messages can be replayed offline with the `replay_messages` tool.  It runs on host and
-device and supports the following options:
-
-1. `interesting` - this prints 'interesting' statistics for each of the log buffer types (simple,
-   chatty, serialized).  The statistics are:
-    1. Log Entry Count
-    2. Size (the uncompressed size of the log messages in bytes)
-    3. Overhead (the total cost of the log messages in memory in bytes)
-    4. Range (the range of time that the logs cover in seconds)
-2. `memory_usage BUFFER_TYPE` - this prints the memory usage (sum of private dirty pages of the
-  `replay_messages` process).  Note that the input file is mmap()'ed as RO/Shared so it does not
-  appear in these dirty pages, and a baseline is taken before allocating the log buffers, so only
-  their contributions are measured.  The tool outputs the memory usage every 100,000 messages.
-3. `latency BUFFER_TYPE` - this prints statistics of the latency of the Log() function for the given
-  buffer type.  It specifically prints the 1st, 2nd, and 3rd quartiles; the 95th, 99th, and 99.99th
-  percentiles; and the maximum latency.
-4. `print_logs BUFFER_TYPE [buffers] [print_point]` - this prints the logs as processed by the given
-  buffer_type from the buffers specified by `buffers` starting after the number of logs specified by
-  `print_point` have been logged.  This acts as if a user called `logcat` immediately after the
-  specified logs have been logged, which is particularly useful since it will show the chatty
-  pruning messages at that point.  It additionally prints the statistics from `logcat -S` after the
-  logs.
-  `buffers` is a comma separated list of the numeric buffer id values from `<android/log.h>`.  For
-  example, `0,1,3` represents the main, radio, and system buffers.  It can can also be `all`.
-  `print_point` is an positive integer.  If it is unspecified, logs are printed after the entire
-  input file is consumed.
-5. `nothing BUFFER_TYPE` - this does nothing other than read the input file and call Log() for the
-  given buffer type.  This is used for profiling CPU usage of strictly the log buffer.

-
-      "Object" form shall mean any form resulting from mechanical
-      transformation or translation of a Source form, including but
-      not limited to compiled object code, generated documentation,
-      and conversions to other media types.
-

-      Object form, made available under the License, as indicated by a
-      copyright notice that is included in or attached to the work
-      (an example is provided in the Appendix below).
-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain

-      the Work and Derivative Works thereof.
-
-      "Contribution" shall mean any work of authorship, including
-      the original version of the Work and any modifications or additions
-      to that Work or Derivative Works thereof, that is intentionally

-
-      "Contributor" shall mean Licensor and any individual or Legal Entity
-      on behalf of whom a Contribution has been received by Licensor and

-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the
-      Work and such Derivative Works in Source or Object form.
-
-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,

-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and

-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
