// Chromium documentation:

//
// These are the differences between the specification and the implementation:
// - Constructors do not use 'constexpr' as it is a C++14 extension.
// - 'constexpr' might be missing in some places for reasons specified locally.
// - No exceptions are thrown, because they are banned from Chromium.

// - All the non-members are in the 'base' namespace instead of 'std'.
//
// Note that T cannot have a constructor T(Optional<T>) etc. Optional<T>
// PERFETTO_CHECKs T's constructor (specifically via IsConvertibleFromOptional),
// and in the PERFETTO_CHECK whether T can be constructible from Optional<T>,
// which is recursive so it does not work. As of Feb 2018, std::optional C++17

// 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", "-"});

// 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.

// 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
//    subclasses the TracingSession object (TracingSessionImpl) and returns it.
// 3. The tracing muxer identifies the backend (according to the args passed to
//    NewTrace), creates a new Consumer and connects to it.
// 4. When the API client calls Start()/Stop()/ReadTrace() methods, the
//    TracingMuxer forwards them to the consumer associated to the
//    TracingSession. Likewise for callbacks coming from the consumer-side of
//    the service.

// 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.

// 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

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.

// The problem this is solving is the following: For each result argument of the
// methods generated from the .proto file:
// - The client wants to see something on which it can Bind() a callback, which
//   is invoked asynchronously once reply is received from the host.
// - The host wants to expose something to user code that implements the IPC
//   methods to allow them to provide an asynchronous reply back to the client.
//   Eventually even more than once, for the case streaming replies.
//
// In both cases we want to make sure that callbacks don't get lost along the
// way. To address this, this class will automatically reject the callbacks
// if they are not resolved at destructor time (or the object is std::move()'d).
//
// The client is supposed to use this class as follows:
//   class GreeterProxy {
//      void SayHello(const HelloRequest&, Deferred<HelloReply> reply)
//   }
//  ...
//  Deferred<HelloReply> reply;
//  reply.Bind([] (AsyncResult<HelloReply> reply) {
//    std::cout << reply.success() ? reply->message : "failure";
//  });

//
// The host instead is supposed to use this as follows:
//   class GreeterImpl : public Greeter {
//     void SayHello(const HelloRequest& req, Deferred<HelloReply> reply) {
//        AsyncResult<HelloReply> reply = AsyncResult<HelloReply>::Create();
//        reply->set_greeting("Hello " + req.name)
//        reply.Resolve(std::move(reply));
//     }
//   }

// and the reply can continue asynchronously later.
