-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.

-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;
-    };

-        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.

-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.

-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.

-// 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.

-
-      "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

-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable

-
-   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

-          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.

- *   status: the equivalent child status as populated by wait(status). This
- *           value is only valid when logwrap successfully completes. If NULL
- *           the return value of the child will be the function's return value.
- *   forward_signals: set to true if you want to forward SIGINT, SIGQUIT, and
- *           SIGHUP to the child process, while it is running.  You likely do
- *           not need to use this; it is primarily for the logwrapper
- *           executable itself.
- *   log_target: Specify where to log the output of the child, either LOG_NONE,
- *           LOG_ALOG (for the Android system log), LOG_KLOG (for the kernel
- *           log), or LOG_FILE (and you need to specify a pathname in the
- *           file_path argument, otherwise pass NULL).  These are bit fields,
- *           and can be OR'ed together to log to multiple places.
- *   abbreviated: If true, capture up to the first 100 lines and last 4K of
- *           output from the child.  The abbreviated output is not dumped to
- *           the specified log until the child has exited.
- *   file_path: if log_target has the LOG_FILE bit set, then this parameter
- *           must be set to the pathname of the file to log to.
- *
- * Return value:
- *   0 when logwrap successfully run the child process and captured its status
- *   -1 when an internal error occurred
- *   -ECHILD if status is NULL and the child didn't exit properly
- *   the return value of the child if it exited properly and status is NULL
