+# 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 |
++----------+ | | Transport+-------------+ (DEVICE) |
+ | | | +----------+
++----------- | | |
+| ADB | v + | +----------+
+| CLIENT +--------->SmartSocket | (USB)| ADBD |
++----------+ ^ | (TCP/IP) Transport+-------------+ (DEVICE) |
+ | | | +----------+
++----------+ | | |
+| DDMLIB | | | Transport+--+ +----------+
+| CLIENT +----------+ | | | (TCP/IP)| ADBD |
++----------+ +------------------------+ +----------|(EMULATOR)|
+ +----------+
+```
+
+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 Queue------------------+ |
+ | | | |
+ | | 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.
+
+## adbd <-> APPPLICATION communication
+
+This pipeline is detailed in [services.cpp](services.cpp). The JDWP extension implemented by Dalvik/ART are documented in:

-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.

- } string;
- struct {

- struct android_log_header_t {
- uint8_t id;
- uint16_t tid;
- log_time realtime;
- };
-
- struct log_time {
- uint32_t tv_sec = 0;

-
- 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.

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

- *
- * - Sending log messages eats CPU and slow down your application and the

- *
- * - The circular log buffer is pretty small, so sending many messages

-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.";

-** --------------------------------------------
-** 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

-**
-** 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

- *
- * 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

-General options:
- -b, --buffer=<buffer> Request alternate ring buffer(s):
- main system radio events crash default all
- Additionally, 'kernel' for userdebug and eng builds, and
- 'security' for Device Owner installations.
- Multiple -b parameters or comma separated list of buffers are
- allowed. Buffers are interleaved.
- Default -b main,system,crash,kernel.
- -L, --last Dump logs from prior to last reboot from pstore.
- -c, --clear Clear (flush) the entire log and exit.
- if -f is specified, clear the specified file and its related rotated
- log files instead.
- if -L is specified, clear pstore log instead.
- -d Dump the log and then exit (don't block).
- --pid=<pid> Only print logs from the given pid.
- --wrap Sleep for 2 hours or when buffer about to wrap whichever
- comes first. Improves efficiency of polling by providing
- an about-to-wrap wakeup.
-
-Formatting:
- -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.

-// 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(),

-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.

-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.
