// Crash keys are very simple global variables with static-storage that
// are reported on crash time for managed crashes (CHECK/FATAL/Watchdog).
// - Translation units can define a CrashKey and register it at some point
// during initialization.
// - CrashKey instances must be long-lived. They should really be just global
// static variable in the anonymous namespace.
// Example:
// subsystem_1.cc
// CrashKey g_client_id("ipc_client_id");
// ...
// OnIpcReceived(client_id) {
// g_client_id.Set(client_id);
// ... // Process the IPC
// g_client_id.Clear();
// }
// Or equivalently:
// OnIpcReceived(client_id) {
// auto scoped_key = g_client_id.SetScoped(client_id);
// ... // Process the IPC
// }
//
// If a crash happens while processing the IPC, the crash report will
// have a line "ipc_client_id: 42".
//
// Thread safety considerations:
// CrashKeys can be registered and set/cleared from any thread.
// There is no compelling use-case to have full acquire/release consistency when
// setting a key. This means that if a thread crashes immediately after a
// crash key has been set on another thread, the value printed on the crash
// report could be incomplete. The code guarantees defined behavior and does
// not rely on null-terminated string (in the worst case 32 bytes of random
// garbage will be printed out).
// The tests live in logging_unittest.cc.

// This class has just an Append() method to insert events into the buffer and
// a Read() to read the events in FIFO order. Read() is non-destructive.
//
// Thread safety considerations:
// - The Append() method can be called concurrently by several threads, unless
// there are > kLogRingBufEntries concurrent threads. Even if that happens,
// case some events will contain a mix of strings but the behavior of
// further Append() and Read() is still defined.
// - The Read() method is not thread safe but it's fine in practice. Even if
// it's called concurrently with other Append(), it only causes some partial
// events to be emitted in output.
// In both cases, we never rely purely on \0, all operations are size-bound.
//

// Handles creation and lifecycle management of subprocesses, taking care of
// all subtleties involved in handling processes on UNIX.
// This class allows to deal with macro two use-cases:
// 1) fork() + exec() equivalent: for spawning a brand new process image.
// This happens when |args.exec_cmd| is not empty.
// This is safe to use even in a multi-threaded environment.
// 2) fork(): for spawning a process and running a function.
// This happens when |args.posix_entrypoint_for_testing| is not empty.
// This is intended only for tests as it is extremely subtle.
// This mode must be used with extreme care. Before the entrypoint is
// invoked all file descriptors other than stdin/out/err and the ones
// specified in |args.preserve_fds| will be closed, to avoid each process
// retaining a dupe of other subprocesses pipes. This however means that
// any non trivial calls (including logging) must be avoided as they might
// refer to FDs that are now closed. The entrypoint should really be used
// just to signal a pipe or similar for synchronizing sequencing in tests.
//
// This class allows to control stdin/out/err pipe redirection and takes care
// of keeping all the pipes pumped (stdin) / drained (stdout/err), in a similar
// fashion of python's subprocess.Communicate()
// stdin: is always piped and closed once the |args.input| buffer is written.
// stdout/err can be either:
// - dup()ed onto the parent process stdout/err.
// - redirected onto /dev/null.
// - piped onto a buffer (see output() method). There is only one output
// buffer in total. If both stdout and stderr are set to kBuffer mode, they
// will be merged onto the same. There doesn't seem any use case where they
// are needed distinctly.
//
// Some caveats worth mentioning:
// - It always waitpid()s, to avoid leaving zombies around. If the process is
// not terminated by the time the destructor is reached, the dtor will
// send a SIGKILL and wait for the termination.
// - After fork()-ing it will close all file descriptors, preserving only
// stdin/out/err and the fds listed in |args.preserve_fds|.
// - On Linux/Android, the child process will be SIGKILL-ed if the calling
// thread exists, even if the Subprocess is std::move()-d onto another thread.
// This happens by virtue PR_SET_PDEATHSIG, which is used to avoid that
// child processes are leaked in the case of a crash of the parent (frequent
// in tests). However, the child process might still be leaked if execing
// a setuid/setgid binary (see man 2 prctl).
//
// Usage:
// base::Subprocess p({"/bin/cat", "-"});
// (or equivalently:

// This file defines the binary interface of the memory buffers shared between
// Producer and Service. This is a long-term stable ABI and has to be backwards
// compatible to deal with mismatching Producer and Service versions.
//
// Overview
// --------
// SMB := "Shared Memory Buffer".
// In the most typical case of a multi-process architecture (i.e. Producer and
// Service are hosted by different processes), a Producer means almost always
// a "client process producing data" (almost: in some cases a process might host
// > 1 Producer, if it links two libraries, independent of each other, that both
// use Perfetto tracing).
// The Service has one SMB for each Producer.
// A producer has one or (typically) more data sources. They all share the same
// SMB.
// The SMB is a staging area to decouple data sources living in the Producer
// and allow them to do non-blocking async writes.
// The SMB is *not* the ultimate logging buffer seen by the Consumer. That one
// is larger (~MBs) and not shared with Producers.
// Each SMB is small, typically few KB. Its size is configurable by the producer
// within a max limit of ~MB (see kMaxShmSize in tracing_service_impl.cc).
// The SMB is partitioned into fixed-size Page(s). The size of the Pages are
// determined by each Producer at connection time and cannot be changed.
// Hence, different producers can have SMB(s) that have a different Page size
// from each other, but the page size will be constant throughout all the
// lifetime of the SMB.
// Page(s) are partitioned by the Producer into variable size Chunk(s):
//
// +------------+ +--------------------------+
// | Producer 1 | <-> | SMB 1 [~32K - 1MB] |
// +------------+ +--------+--------+--------+
// | Page | Page | Page |
// +--------+--------+--------+
// | Chunk | | Chunk |
// +--------+ Chunk +--------+ <----+
// | Chunk | | Chunk | |
// +--------+--------+--------+ +---------------------+
// | Service |
// +------------+ +--------------------------+ +---------------------+
// | Producer 2 | <-> | SMB 2 [~32K - 1MB] | /| large ring buffers |
// +------------+ +--------+--------+--------+ <--+ | (100K - several MB) |
// | Page | Page | Page | +---------------------+
// +--------+--------+--------+
// | Chunk | | Chunk |
// +--------+ Chunk +--------+
// | Chunk | | Chunk |
// +--------+--------+--------+
//
// * Sizes of both SMB and ring buffers are purely indicative and decided at
// configuration time by the Producer (for SMB sizes) and the Consumer (for the
// final ring buffer size).
// Page
// ----
// A page is a portion of the shared memory buffer and defines the granularity
// of the interaction between the Producer and tracing Service. When scanning
// the shared memory buffer to determine if something should be moved to the
// central logging buffers, the Service most of the times looks at and moves
// whole pages. Similarly, the Producer sends an IPC to invite the Service to
// drain the shared memory buffer only when a whole page is filled.
// Having fixed the total SMB size (hence the total memory overhead), the page
// size is a triangular tradeoff between:
// 1) IPC traffic: smaller pages -> more IPCs.
// 2) Producer lock freedom: larger pages -> larger chunks -> data sources can
// write more data without needing to swap chunks and synchronize.
// 3) Risk of write-starving the SMB: larger pages -> higher chance that the
// Service won't manage to drain them and the SMB remains full.
// The page size, on the other side, has no implications on wasted memory due to
// fragmentations (see Chunk below).
// The size of the page is chosen by the Service at connection time and stays
// fixed throughout all the lifetime of the Producer. Different producers (i.e.
// ~ different client processes) can use different page sizes.
// The page size must be an integer multiple of 4k (this is to allow VM page
// stealing optimizations) and obviously has to be an integer divisor of the
// total SMB size.
// Chunk
// -----
// A chunk is a portion of a Page which is written and handled by a Producer.
// A chunk contains a linear sequence of TracePacket(s) (the root proto).
// A chunk cannot be written concurrently by two data sources. Protobufs must be
// encoded as contiguous byte streams and cannot be interleaved. Therefore, on
// the Producer side, a chunk is almost always owned exclusively by one thread
// (% extremely peculiar slow-path cases).
// Chunks are essentially single-writer single-thread lock-free arenas. Locking
// happens only when a Chunk is full and a new one needs to be acquired.
// Locking happens only within the scope of a Producer process. There is no
// inter-process locking. The Producer cannot lock the Service and viceversa.
// In the worst case, any of the two can starve the SMB, by marking all chunks
// as either being read or written. But that has the only side effect of
// losing the trace data.
// The Producer can decide to partition each page into a number of limited
// configurations (e.g., 1 page == 1 chunk, 1 page == 2 chunks and so on).
// TracePacket
// -----------
// Is the atom of tracing. Putting aside pages and chunks a trace is merely a
// sequence of TracePacket(s). TracePacket is the root protobuf message.
// A TracePacket can span across several chunks (hence even across several
// pages). A TracePacket can therefore be >> chunk size, >> page size and even
// >> SMB size. The Chunk header carries metadata to deal with the TracePacket
// splitting case.
// Use only explicitly-sized types below. DO NOT use size_t or any architecture
// dependent size (e.g. size_t) in the struct fields. This buffer will be read
// and written by processes that have a different bitness in the same OS.
// Instead it's fine to assume little-endianess. Big-endian is a dream we are
// not currently pursuing.

// This class acts as a bridge between the public API and the TracingBackend(s).

// bookkeeping to map data source instances and trace writers to the various
// backends. It deals with N data sources, M backends (1 backend == 1 tracing
// service == 1 producer connection) and T concurrent tracing sessions.
//
// Handing data source registration and start/stop flows [producer side]:
// ----------------------------------------------------------------------
// 1. The API client subclasses perfetto::DataSource and calls
// DataSource::Register<MyDataSource>(). In turn this calls into the
// TracingMuxer.
// 2. The tracing muxer iterates through all the backends (1 backend == 1
// service == 1 producer connection) and registers the data source on each
// backend.
// 3. When any (services behind a) backend starts tracing and requests to start
// that specific data source, the TracingMuxerImpl constructs a new instance
// of MyDataSource and calls the OnStart() method.
//
// Controlling trace and retrieving trace data [consumer side]:
// ------------------------------------------------------------
// 1. The API client calls Tracing::NewTrace(), returns a RAII TracingSession
// object.
// 2. NewTrace() calls into internal::TracingMuxer(Impl). TracingMuxer

// Bit 31: 1 if the field is allowed, 0 if disallowed.
// Only directly indexed fields can be 0 (it doesn't make sense to add
// a range and then say "btw it's NOT allowed".. don't add it then.

// can be directly passed through in output. No recursion is needed.
// 0x7ffffffe: The field is string field which needs to be filtered.
// [0, 7ffffffd]: The field is a nested submessage. The value is the index
// that must be passed as first argument to the next Query() calls.

// A class to filter binary-encoded proto messages using an allow-list of field
// ids, also known as "filter bytecode". The filter determines which fields are
// allowed to be passed through in output and strips all the other fields.
// See go/trace-filtering for full design.
// This class takes in input:
// 1) The filter bytecode, loaded once via the LoadFilterBytecode() method.
// 2) A proto-encoded binary message. The message doesn't have to be contiguous,
// it can be passed as an array of arbitrarily chunked fragments.
// The FilterMessage*() method returns in output a proto message, stripping out
// all unknown fields. If the input is malformed (e.g., unknown proto field wire
// types, lengths out of bound) the whole filtering failed and the |error| flag
// of the FilteredMessage object is set to true.
// The filtering operation is based on rewriting a copy of the message into a
// self-allocated buffer, which is then returned in the output. The input buffer
// is NOT altered.
// Note also that the process of rewriting the protos gets rid of most redundant
// varint encoding (if present). So even if all fields are allow-listed, the
// output might NOT be bitwise identical to the input (but it will be
// semantically equivalent).
// Furthermore the enable_field_usage_tracking() method allows to keep track of
// a histogram of allowed / denied fields. It slows down filtering and is
// intended only on host tools.

class TracePacket;
// The main buffer, owned by the tracing service, where all the trace data is
// ultimately stored into. The service will own several instances of this class,
// at least one per active consumer (as defined in the |buffers| section of
// trace_config.proto) and will copy chunks from the producer's shared memory
// buffers into here when a CommitData IPC is received.
//
// Writing into the buffer
// -----------------------
// Data is copied from the SMB(s) using CopyChunkUntrusted(). The buffer will
// hence contain data coming from different producers and different writer
// sequences, more specifically:
// - The service receives data by several producer(s), identified by their ID.
// - Each producer writes several sequences identified by the same WriterID.
// (they correspond to TraceWriter instances in the producer).
// - Each Writer writes, in order, several chunks.
// - Each chunk contains zero, one, or more TracePacket(s), or even just
// fragments of packets (when they span across several chunks).
//
// So at any point in time, the buffer will contain a variable number of logical
// sequences identified by the {ProducerID, WriterID} tuple. Any given chunk
// will only contain packets (or fragments) belonging to the same sequence.
//
// The buffer operates by default as a ring buffer.
// It has two overwrite policies:
// 1. kOverwrite (default): if the write pointer reaches the read pointer, old
// unread chunks will be overwritten by new chunks.
// 2. kDiscard: if the write pointer reaches the read pointer, unread chunks
// are preserved and the new chunks are discarded. Any future write becomes
// a no-op, even if the reader manages to fully catch up. This is because
// once a chunk is discarded, the sequence of packets is broken and trying
// to recover would be too hard (also due to the fact that, at the same
// time, we allow out-of-order commits and chunk re-writes).
//
// Chunks are (over)written in the same order of the CopyChunkUntrusted() calls.
// When overwriting old content, entire chunks are overwritten or clobbered.
// The buffer never leaves a partial chunk around. Chunks' payload is copied
// as-is, but their header is not and is repacked in order to keep the
// ProducerID around.
//
// Chunks are stored in the buffer next to each other. Each chunk is prefixed by
// an inline header (ChunkRecord), which contains most of the fields of the
// SharedMemoryABI ChunkHeader + the ProducerID + the size of the payload.
// It's a conventional binary object stream essentially, where each ChunkRecord
// tells where it ends and hence where to find the next one, like this:
//
// .-------------------------. 16 byte boundary
// | ChunkRecord: 16 bytes |
// | - chunk id: 4 bytes |
// | - producer id: 2 bytes |
// | - writer id: 2 bytes |
// | - #fragments: 2 bytes |
// +-----+ - record size: 2 bytes |
// | | - flags+pad: 4 bytes |
// | +-------------------------+
// | | |
// | : Chunk payload :
// | | |
// | +-------------------------+
// | | Optional padding |
// +---> +-------------------------+ 16 byte boundary
// | ChunkRecord |
// : :
// Chunks stored in the buffer are always rounded up to 16 bytes (that is
// sizeof(ChunkRecord)), in order to avoid further inner fragmentation.
// Special "padding" chunks can be put in the buffer, e.g. in the case when we
// try to write a chunk of size N while the write pointer is at the end of the
// buffer, but the write pointer is < N bytes from the end (and hence needs to
// wrap over).
// Because of this, the buffer is self-describing: the contents of the buffer
// can be reconstructed by just looking at the buffer content (this will be
// quite useful in future to recover the buffer from crash reports).
//
// However, in order to keep some operations (patching and reading) fast, a
// lookaside index is maintained (in |index_|), keeping each chunk in the buffer
// indexed by their {ProducerID, WriterID, ChunkID} tuple.
//
// Patching data out-of-band
// -------------------------
// This buffer also supports patching chunks' payload out-of-band, after they
// have been stored. This is to allow producers to backfill the "size" fields
// of the protos that spawn across several chunks, when the previous chunks are
// returned to the service. The MaybePatchChunkContents() deals with the fact
// that a chunk might have been lost (because of wrapping) by the time the OOB
// IPC comes.
//
// Reading from the buffer
// -----------------------
// This class supports one reader only (the consumer). Reads are NOT idempotent
// as they move the read cursors around. Reading back the buffer is the most
// conceptually complex part. The ReadNextTracePacket() method operates with
// whole packet granularity. Packets are returned only when all their fragments
// are available.
// This class takes care of:
// - Gluing packets within the same sequence, even if they are not stored
// adjacently in the buffer.
// - Re-ordering chunks within a sequence (using the ChunkID, which wraps).
// - Detecting holes in packet fragments (because of loss of chunks).
// Reads guarantee that packets for the same sequence are read in FIFO order
// (according to their ChunkID), but don't give any guarantee about the read
// order of packets from different sequences, see comments in
// ReadNextTracePacket() below.

// CircularQueue is a push-back-only / pop-front-only queue with the following
// characteristics:
// - The storage is based on a flat circular buffer. Beginning and end wrap
// as necessary, to keep pushes and pops O(1) as long as capacity expansion is
// not required.
// - Capacity is automatically expanded like in a std::vector. Expansion has a
// O(N) cost.
// - It allows random access, allowing in-place std::sort.
// - Iterators are not stable. Mutating the container invalidates all iterators.
// - It doesn't bother with const-correctness.
//
// Implementation details:
// Internally, |begin|, |end| and iterators use 64-bit monotonic indexes, which
// are incremented as if the queue was backed by unlimited storage.
// Even assuming that elements are inserted and removed every nanosecond, 64 bit
// is enough for 584 years.
// Wrapping happens only when addressing elements in the underlying circular
// storage. This limits the complexity and avoiding dealing with modular
// arithmetic all over the places.

// Deserializes incoming frames, taking care of buffering and tokenization.
// Used by both host and client to decode incoming frames.
//
// Which problem does it solve?
// ----------------------------
// The wire protocol is as follows:
// [32-bit frame size][proto-encoded Frame], e.g:
// [06 00 00 00][00 11 22 33 44 55 66]
// [02 00 00 00][AA BB]
// [04 00 00 00][CC DD EE FF]
// However, given that the socket works in SOCK_STREAM mode, the recv() calls
// might see the following:
// 06 00 00
// 00 00 11 22 33 44 55
// 66 02 00 00 00 ...
// This class takes care of buffering efficiently the data received, without
// making any assumption on how the incoming data will be chunked by the socket.
// For instance, it is possible that a recv() doesn't produce any frame (because
// it received only a part of the frame) or produces more than one frame.
//
// Usage
// -----
// Both host and client use this as follows:
//
// auto buf = rpc_frame_decoder.BeginReceive();
// size_t rsize = socket.recv(buf.first, buf.second);
// rpc_frame_decoder.EndReceive(rsize);
// while (Frame frame = rpc_frame_decoder.PopNextFrame()) {
// ... process |frame|
// }
//
// Design goals:
// -------------
// - Optimize for the realistic case of each recv() receiving one or more
// whole frames. In this case no memmove is performed.
// - Guarantee that frames lay in a virtually contiguous memory area.
// This allows to use the protobuf-lite deserialization API (scattered
// deserialization is supported only by libprotobuf-full).
// - Put a hard boundary to the size of the incoming buffer. This is to prevent
// that a malicious sends an abnormally large frame and OOMs us.
// - Simplicity: just use a linear mmap region. No reallocations or scattering.
// Takes care of madvise()-ing unused memory.
