-# crash_reporter
-
-`crash_reporter` is a deamon running on the device that saves the call stack of
-crashing programs. It makes use of the
-[Breakpad](https://chromium.googlesource.com/breakpad/breakpad/) library.
-
-During a build, Breakpad symbol files are generated for all binaries.  They are
-packaged into a zip file when running `m dist`, so that a developer can upload
-them to the crash server.
-
-On a device, if the user has opted in to metrics and crash reporting, a
-Breakpad minidump is generated when an executable crashes, which is then
-uploaded to the crash server.
-
-On the crash server, it compares the minidump's signature to the symbol files
-that the developer has uploaded, and extracts and symbolizes the stack trace
-from the minidump.
-
-## SELinux policies
-
-In order to correctly generate a minidump, `crash_reporter` needs to be given
-the proper SELinux permissions for accessing the domain of the crashing
-executable.  By default, `crash_reporter` has only been given access to a select
-number of system domains, such as `metricsd`, `weave`, and `update_engine`.  If
-a developer wants their executable's crashes to be caught by `crash_reporter`,
-they will have to set their SELinux policies in their .te file to allow
-`crash_reporter` access to their domain.  This can be done through a simple
-[macro](https://android.googlesource.com/device/generic/brillo/+/master/sepolicy/te_macros):
-
-    allow_crash_reporter(domain_name)
-
-Replace *domain_name* with whatever domain is assigned to the executable in
-the `file_contexts` file.
-
-## Configuration
-
-`crash_reporter` has a few different configuration options that have to be set.
-
-- Crashes are only handled and uploaded if analytics reporting is enabled,
-  either via the weave call to set `_metrics.enableAnalyticsReporting` or by
-  manually creating the file `/data/misc/metrics/enabled` (for testing only).
-- The `BRILLO_CRASH_SERVER` make variable should be set in the `product.mk`
-  file to the URL of the crash server.  For Brillo builds, it is set
-  automatically through the product configuration.  Setting this variable will
-  populate the `/etc/os-release.d/crash_server` file on the device, which is
-  read by `crash_sender`.
-- The `BRILLO_PRODUCT_ID` make variable should be set in the `product.mk` file
-  to the product's ID.  For Brillo builds, it is set automatically through the
-  product configuration.  Setting this variable will populate the
-  `/etc/os-release.d/product_id`, which is read by `crash_sender`.
-
-## Uploading crash reports in *eng* builds
-
-By default, crash reports are only uploaded to the server for production
-*user* and *userdebug* images.  In *eng* builds, with crash reporting enabled
-the device will generate minidumps for any crashing executables but will not
-send them to the crash server.  If a developer does want to force an upload,
-they can do so by issuing the command `SECONDS_SEND_SPREAD=5 FORCE_OFFICIAL=1
-crash_sender` from an ADB shell.  This will send the report to the server, with
-the *image_type* field set to *force-official* so that these reports can be
-differentiated from normal reports.

- * using their hashes as buckets in a UMA sparse histogram.  It also invokes

+
+// SOME COMMENTS ABOUT USAGE:
+
+// This provides primarily wp<> weak pointer types and RefBase, which work
+// together with sp<> from <StrongPointer.h>.
+
+// sp<> (and wp<>) are a type of smart pointer that use a well defined protocol
+// to operate. As long as the object they are templated with implements that
+// protocol, these smart pointers work. In several places the platform
+// instantiates sp<> with non-RefBase objects; the two are not tied to each
+// other.
+
+// RefBase is such an implementation and it supports strong pointers, weak
+// pointers and some magic features for the binder.
+
+// So, when using RefBase objects, you have the ability to use strong and weak
+// pointers through sp<> and wp<>.
+
+// Normally, when the last strong pointer goes away, the object is destroyed,
+// i.e. it's destructor is called. HOWEVER, parts of its associated memory is not
+// freed until the last weak pointer is released.
+
+// Weak pointers are essentially "safe" pointers. They are always safe to
+// access through promote(). They may return nullptr if the object was
+// destroyed because it ran out of strong pointers. This makes them good candidates
+// for keys in a cache for instance.
+
+// Weak pointers remain valid for comparison purposes even after the underlying
+// object has been destroyed. Even if object A is destroyed and its memory reused
+// for B, A remaining weak pointer to A will not compare equal to one to B.
+// This again makes them attractive for use as keys.
+
+// How is this supposed / intended to be used?
+
+// Our recommendation is to use strong references (sp<>) when there is an
+// ownership relation. e.g. when an object "owns" another one, use a strong
+// ref. And of course use strong refs as arguments of functions (it's extremely
+// rare that a function will take a wp<>).
+
+// Typically a newly allocated object will immediately be used to initialize
+// a strong pointer, which may then be used to construct or assign to other
+// strong and weak pointers.
+
+// Use weak references when there are no ownership relation. e.g. the keys in a
+// cache (you cannot use plain pointers because there is no safe way to acquire
+// a strong reference from a vanilla pointer).
+
+// This implies that two objects should never (or very rarely) have sp<> on
+// each other, because they can't both own each other.
+
+
+// Caveats with reference counting
+
+// Obviously, circular strong references are a big problem; this creates leaks
+// and it's hard to debug -- except it's in fact really easy because RefBase has
+// tons of debugging code for that. It can basically tell you exactly where the
+// leak is.
+
+// Another problem has to do with destructors with side effects. You must
+// assume that the destructor of reference counted objects can be called AT ANY
+// TIME. For instance code as simple as this:
+
+// void setStuff(const sp<Stuff>& stuff) {
+//   std::lock_guard<std::mutex> lock(mMutex);
+//   mStuff = stuff;
+// }
+
+// is very dangerous. This code WILL deadlock one day or another.
+
+// What isn't obvious is that ~Stuff() can be called as a result of the
+// assignment. And it gets called with the lock held. First of all, the lock is
+// protecting mStuff, not ~Stuff(). Secondly, if ~Stuff() uses its own internal
+// mutex, now you have mutex ordering issues.  Even worse, if ~Stuff() is
+// virtual, now you're calling into "user" code (potentially), by that, I mean,
+// code you didn't even write.
+
+// A correct way to write this code is something like:
+
+// void setStuff(const sp<Stuff>& stuff) {
+//   std::unique_lock<std::mutex> lock(mMutex);
+//   sp<Stuff> hold = mStuff;
+//   mStuff = stuff;
+//   lock.unlock();
+// }
+
+// More importantly, reference counted objects should do as little work as
+// possible in their destructor, or at least be mindful that their destructor
+// could be called from very weird and unintended places.
+
+// Other more specific restrictions for wp<> and sp<>:
+
+// Do not construct a strong pointer to "this" in an object's constructor.
+// The onFirstRef() callback would be made on an incompletely constructed
+// object.
+// Construction of a weak pointer to "this" in an object's constructor is also
+// discouraged. But the implementation was recently changed so that, in the
+// absence of extendObjectLifetime() calls, weak pointers no longer impact
+// object lifetime, and hence this no longer risks premature deallocation,
+// and hence usually works correctly.
+
+// Such strong or weak pointers can be safely created in the RefBase onFirstRef()
+// callback.
+
+// Use of wp::unsafe_get() for any purpose other than debugging is almost
+// always wrong.  Unless you somehow know that there is a longer-lived sp<> to
+// the same object, it may well return a pointer to a deallocated object that
+// has since been reallocated for a different purpose. (And if you know there
+// is a longer-lived sp<>, why not use an sp<> directly?) A wp<> should only be
+// dereferenced by using promote().
+
+// Any object inheriting from RefBase should always be destroyed as the result
+// of a reference count decrement, not via any other means.  Such objects
+// should never be stack allocated, or appear directly as data members in other
+// objects. Objects inheriting from RefBase should have their strong reference
+// count incremented as soon as possible after construction. Usually this
+// will be done via construction of an sp<> to the object, but may instead
+// involve other means of calling RefBase::incStrong().
+// Explicitly deleting or otherwise destroying a RefBase object with outstanding
+// wp<> or sp<> pointers to it will result in an abort or heap corruption.
+
+// It is particularly important not to mix sp<> and direct storage management
+// since the sp from raw pointer constructor is implicit. Thus if a RefBase-
+// -derived object of type T is managed without ever incrementing its strong
+// count, and accidentally passed to f(sp<T>), a strong pointer to the object
+// will be temporarily constructed and destroyed, prematurely deallocating the
+// object, and resulting in heap corruption. None of this would be easily
+// visible in the source.
+
+// Extra Features:
+
+// RefBase::extendObjectLifetime() can be used to prevent destruction of the
+// object while there are still weak references. This is really special purpose
+// functionality to support Binder.
+
+// Wp::promote(), implemented via the attemptIncStrong() member function, is
+// used to try to convert a weak pointer back to a strong pointer.  It's the
+// normal way to try to access the fields of an object referenced only through
+// a wp<>.  Binder code also sometimes uses attemptIncStrong() directly.
+
+// RefBase provides a number of additional callbacks for certain reference count
+// events, as well as some debugging facilities.
+
+// Debugging support can be enabled by turning on DEBUG_REFS in RefBase.cpp.
+// Otherwise little checking is provided.
+
+// Thread safety:
+
+// Like std::shared_ptr, sp<> and wp<> allow concurrent accesses to DIFFERENT
+// sp<> and wp<> instances that happen to refer to the same underlying object.
+// They do NOT support concurrent access (where at least one access is a write)
+// to THE SAME sp<> or wp<>.  In effect, their thread-safety properties are
+// exactly like those of T*, NOT atomic<T*>.

+/*
+ * Support routines to send messages to the Android in-kernel log buffer,
+ * which can later be accessed through the 'logcat' utility.
+ *
+ * Each log message must have
+ *   - a priority
+ *   - a log tag
+ *   - some text
+ *
+ * The tag normally corresponds to the component that emits the log message,
+ * and should be reasonably small.
+ *
+ * Log message text may be truncated to less than an implementation-specific
+ * limit (e.g. 1023 characters max).
+ *
+ * Note that a newline character ("\n") will be appended automatically to your
+ * log message, if not already there. It is not possible to send several messages
+ * and have them appear on a single line in logcat.
+ *
+ * PLEASE USE LOGS WITH MODERATION:
+ *
+ *  - Sending log messages eats CPU and slow down your application and the
+ *    system.
+ *
+ *  - The circular log buffer is pretty small (<64KB), sending many messages
+ *    might push off other important log messages from the rest of the system.
+ *
+ *  - In release builds, only send log messages to account for exceptional
+ *    conditions.
+ *
+ * NOTE: These functions MUST be implemented by /system/lib/liblog.so

-Metricsd
-========
-
-The metricsd daemon is used to gather metrics from the platform and application,
-aggregate them and upload them periodically to a server.
-The metrics will then be available in their aggregated form to the developer
-for analysis.
-
-Three components are provided to interact with `metricsd`: `libmetrics`,
-`metrics_collector` and `metrics_client`.
-
-The Metrics Library: libmetrics
--------------------------------
-
-`libmetrics` is a small library that implements the basic C++ API for
-metrics collection. All metrics collection is funneled through this library. The
-easiest and recommended way for a client-side module to collect user metrics is
-to link `libmetrics` and use its APIs to send metrics to `metricsd` for transport to
-UMA. In order to use the library in a module, you need to do the following:
-
-- Add a dependency on the shared library in your Android.mk file:
-  `LOCAL_SHARED_LIBRARIES += libmetrics`
-
-- To access the metrics library API in the module, include the
-  <metrics/metrics_library.h> header file.
-
-- The API is documented in `metrics_library.h`. Before using the API methods, a
-  MetricsLibrary object needs to be constructed and initialized through its
-  Init method.
-
-- Samples are uploaded only if the `/data/misc/metrics/enabled` file exists.
-
-
-Server Side
------------
-
-You will be able to see all uploaded metrics on the metrics dashboard,
-accessible via the developer console.
-
-*** note
-It usually takes a day for metrics to be available on the dashboard.
-***
-
-
-The Metrics Client: metrics_client
-----------------------------------
-
-`metrics_client` is a simple shell command-line utility for sending histogram
-samples and querying `metricsd`. It's installed under `/system/bin` on the target
-platform and uses `libmetrics`.
-
-For usage information and command-line options, run `metrics_client` on the
-target platform or look for "Usage:" in `metrics_client.cc`.
-
-
-The Metrics Daemon: metricsd
-----------------------------
-
-`metricsd` is the daemon that listens for metrics logging calls (via Binder),
-aggregates the metrics and uploads them periodically. This daemon should start as
-early as possible so that depending daemons can log at any time.
-
-`metricsd` is made of two threads that work as follows:
-
-* The binder thread listens for one-way Binder calls, aggregates the metrics in
-  memory (via `base::StatisticsRecorder`) and increments the crash counters when a
-  crash is reported. This thread is kept as simple as possible to ensure the
-  maximum throughput possible.
-* The uploader thread takes care of backing up the metrics to disk periodically
-  (to avoid losing metrics on crashes), collecting metadata about the client
-  (version number, channel, etc..) and uploading the metrics periodically to the
-  server.
-
-
-The Metrics Collector: metrics_collector
-----------------------------------------
-
-metrics_collector is a daemon that runs in the background on the target platform,
-gathers health information about the system and maintains long running counters
-(ex: number of crashes per week).
-
-The recommended way to generate metrics data from a module is to link and use
-libmetrics directly. However, we may not want to add a dependency on libmetrics
-to some modules (ex: kernel). In this case, we can add a collector to
-metrics_collector that will, for example, take measurements and report them
-periodically to metricsd (this is the case for the disk utilization histogram).
-
-
-FAQ
----
-
-### What should my histogram's |min| and |max| values be set at?
-
-You should set the values to a range that covers the vast majority of samples
-that would appear in the field. Note that samples below the |min| will still
-be collected in the underflow bucket and samples above the |max| will end up
-in the overflow bucket. Also, the reported mean of the data will be correct
-regardless of the range.
-
-### How many buckets should I use in my histogram?
-
-You should allocate as many buckets as necessary to perform proper analysis
-on the collected data. Note, however, that the memory allocated in metricsd
-for each histogram is proportional to the number of buckets. Therefore, it is
-strongly recommended to keep this number low (e.g., 50 is normal, while 100
-is probably high).
-
-### When should I use an enumeration (linear) histogram vs. a regular (exponential) histogram?
-
-Enumeration histograms should really be used only for sampling enumerated
-events and, in some cases, percentages. Normally, you should use a regular
-histogram with exponential bucket layout that provides higher resolution at
-the low end of the range and lower resolution at the high end. Regular
-histograms are generally used for collecting performance data (e.g., timing,
-memory usage, power) as well as aggregated event counts.
-
-### How can I test that my histogram was reported correctly?
-
-* Make sure no error messages appear in logcat when you log a sample.
-* Run `metrics_client -d` to dump the currently aggregated metrics. Your
-  histogram should appear in the list.
-* Make sure that the aggregated metrics were uploaded to the server successfully
-  (check for an OK message from `metricsd` in logcat).
-* After a day, your histogram should be available on the dashboard.

-This directory contains the protocol buffers used by the standalone metrics
-uploader. Those protobuffers are copied from the chromium protobuffers from
-https://chromium.googlesource.com/chromium/src/+/master/components/metrics/proto/
-at 3bfe5f2b4c03d2cac718d137ed14cd2c6354bfed.
-
-Any change to this protobuf must first be made to the backend's protobuf and be
-compatible with the chromium protobuffers.
-
-
-Q: Why fork the chromium protobuffers ?
-A: The standalone metrics uploader needs chromium os fields that are not defined
-by the chromium protobufs. Instead of pushing chromium os specific changes to
-chromium, we can add them only to chromium os (and to the backend of course).
-
-
-Q: What's the difference between those protobuffers and chromium's protobuffers?
-A: When the protobuffers were copied, some chromium specific protobuffers were
-not imported:
-* omnibox related protobuffers.
-* performance profiling protobuffers (not used in chromium os).

-//
-// A given metrics sample can be in one of three locations.
-// * in-memory metrics: in memory aggregated metrics, waiting to be staged for
-//   upload.
-// * saved log: protobuf message, written to disk periodically and on shutdown
-//   to make a backup of metrics data for uploading later.
-// * staged log: protobuf message waiting to be uploaded.
-//
-// The service works as follows:
-// On startup, we create the in-memory metrics from the saved log if it exists.
-//
-// Periodically (every |disk_persistence_interval_| seconds), we take a snapshot
-// of the in-memory metrics and save them to disk.
-//
-// Periodically (every |upload_interval| seconds), we:
-// * take a snapshot of the in-memory metrics and create the staged log
-// * save the staged log to disk to avoid losing it if metricsd or the system
-//   crashes between two uploads.
-// * delete the last saved log: all the metrics contained in it are also in the
-//   newly created staged log.
-//
-// On shutdown (SIGINT or SIGTERM), we save the in-memory metrics to disk.
-//
-// Note: the in-memory metrics can be stored in |current_log_| or

- *  - Performance does not matter here, clarity and safety of the code
- *    does however. Documentation is a must.
- *
- *  - Avoid calling C library functions with complex implementations
- *    like malloc() and printf(). You want to depend on simple system
- *    calls instead, which behaviour is not going to be altered in

- *  - Avoid anything that is more complex than simple system calls
- *    until the uid/gid has been dropped to that of a normal user
- *    or you are sure to exit.
- *
- *    This avoids depending on environment variables, system properties
- *    and other external factors that may affect the C library in
- *    unpredictable ways.
- *
- *  - Do not trust user input and/or the filesystem whenever possible.
- *
- *  Read README.TXT for more details.
- *
- *
- *
- * The purpose of this program is to run a command as a specific
- * application user-id. Typical usage is:
- *
- *   run-as <package-name> <command> <args>
- *
- *  The 'run-as' binary is installed with CAP_SETUID and CAP_SETGID file
- *  capabilities, but will check the following:
- *
- *  - that it is invoked from the 'shell' or 'root' user (abort otherwise)
- *  - that '<package-name>' is the name of an installed and debuggable package
- *  - that the package's data directory is well-formed (see package.c)
- *
- *  If so, it will drop to the application's user id / group id, cd to the
- *  package's data directory, then run the command there.
- *
- *  NOTE: In the future it might not be possible to cd to the package's data
- *  directory under that package's user id / group id, in which case this
- *  utility will need to be changed accordingly.
- *
- *  This can be useful for a number of different things on production devices:
- *
- *  - Allow application developers to look at their own applicative data
- *    during development.
- *
- *  - Run the 'gdbserver' binary executable to allow native debugging

-/* README
- *
- * What is this?
- *
- * sdcard is a program that uses FUSE to emulate FAT-on-sdcard style
- * directory permissions (all files are given fixed owner, group, and
- * permissions at creation, owner, group, and permissions are not
- * changeable, symlinks and hardlinks are not createable, etc.
- *
- * See usage() for command line options.
- *
- * It must be run as root, but will drop to requested UID/GID as soon as it
- * mounts a filesystem.  It will refuse to run if requested UID/GID are zero.
- *
- * Things I believe to be true:
- *
- * - ops that return a fuse_entry (LOOKUP, MKNOD, MKDIR, LINK, SYMLINK,
- * CREAT) must bump that node's refcount
- * - don't forget that FORGET can forget multiple references (req->nlookup)
- * - if an op that returns a fuse_entry fails writing the reply to the
- * kernel, you must rollback the refcount to reflect the reference the
- * kernel did not actually acquire
- *
- * This daemon can also derive custom filesystem permissions based on directory
- * structure when requested. These custom permissions support several features:
- *
- * - Apps can access their own files in /Android/data/com.example/ without
- * requiring any additional GIDs.
- * - Separate permissions for protecting directories like Pictures and Music.
- * - Multi-user separation on the same physical device.

+// What is this?
+//
+// sdcard is a program that uses FUSE to emulate FAT-on-sdcard style
+// directory permissions (all files are given fixed owner, group, and
+// permissions at creation, owner, group, and permissions are not
+// changeable, symlinks and hardlinks are not createable, etc.
+//
+// See usage() for command line options.
+//
+// It must be run as root, but will drop to requested UID/GID as soon as it
+// mounts a filesystem.  It will refuse to run if requested UID/GID are zero.
+//
+// Things I believe to be true:
+//
+// - ops that return a fuse_entry (LOOKUP, MKNOD, MKDIR, LINK, SYMLINK,
+// CREAT) must bump that node's refcount
+// - don't forget that FORGET can forget multiple references (req->nlookup)
+// - if an op that returns a fuse_entry fails writing the reply to the
+// kernel, you must rollback the refcount to reflect the reference the
+// kernel did not actually acquire
+//
+// This daemon can also derive custom filesystem permissions based on directory
+// structure when requested. These custom permissions support several features:
+//
+// - Apps can access their own files in /Android/data/com.example/ without
+// requiring any additional GIDs.
+// - Separate permissions for protecting directories like Pictures and Music.
+// - Multi-user separation on the same physical device.
