This patch adds basic access statistics for historic layers
and exposes them in the management API's `LayerMapInfo`.

We record the accesses in the `{Delta,Image}Layer::load()` function
because it's the common path of
* page_service (`Timline::get_reconstruct_data()`)
* Compaction (`PersistentLayer::iter()` and `PersistentLayer::key_iter()`)

The stats survive residence status changes, and record these as well.

When scraping the layer map endpoint to record its evolution over time,
one must account for stat resets because they are in-memory only and
will reset on pageserver restart.
Use the launch timestamp header added by (#3527) to identify pageserver restarts.

 Neon is a serverless open-source alternative to AWS Aurora Postgres. It separates storage and compute and substitutes the PostgreSQL storage layer by redistributing data across a cluster of nodes.
 
-The project used to be called "Zenith". Many of the commands and code comments
-still refer to "zenith", but we are in the process of renaming things.
-
 ## Quick start
-[Join the waitlist](https://neon.tech/) for our free tier to receive your serverless postgres instance. Then connect to it with your preferred postgres client (psql, dbeaver, etc) or use the online SQL editor.
+Try the [Neon Free Tier](https://neon.tech/docs/introduction/technical-preview-free-tier/) to create a serverless Postgres instance. Then connect to it with your preferred Postgres client (psql, dbeaver, etc) or use the online [SQL Editor](https://neon.tech/docs/get-started-with-neon/query-with-neon-sql-editor/). See [Connect from any application](https://neon.tech/docs/connect/connect-from-any-app/) for connection instructions.
 
 Alternatively, compile and run the project [locally](#running-local-installation).
 
 ## Architecture overview
 
-A Neon installation consists of compute nodes and a Neon storage engine.

-Compute nodes are stateless PostgreSQL nodes backed by the Neon storage engine.
+A Neon installation consists of compute nodes and the Neon storage engine. Compute nodes are stateless PostgreSQL nodes backed by the Neon storage engine.
 
 The Neon storage engine consists of two major components:
 - Pageserver. Scalable storage backend for the compute nodes.
-- WAL service. The service receives WAL from the compute node and ensures that it is stored durably.
+- Safekeepers. The safekeepers form a redundant WAL service that received WAL from the compute node, and stores it durably until it has been processed by the pageserver and uploaded to cloud storage.
 
-Pageserver consists of:
-- Repository - Neon storage implementation.
-- WAL receiver - service that receives WAL from WAL service and stores it in the repository.
-- Page service - service that communicates with compute nodes and responds with pages from the repository.
-- WAL redo - service that builds pages from base images and WAL records on Page service request

+    // Short answer: in a multi-threaded program, other threads may have
+    // been inside of critical sections at the time of fork. In the
+    // original process, that was allright, assuming they protected
+    // the critical sections appropriately, e.g., through locks.
+    // Fork adds another process to the mix that
+    //   1. Has a single thread T
+    //   2. In an exact copy of the address space at the time of fork.
+    // A variety of problems scan occur now:
+    //   1. T tries to grab a lock that was locked at the time of fork.
+    //      It will wait forever since in its address space, the lock
+    //      is in state 'taken' but the thread that would unlock it is
+    //      not there.
+    //   2. A rust object that represented some external resource in the
+    //      parent now got implicitly copied by the the fork, even though
+    //      the object's type is not `Copy`. The parent program may use
+    //      non-copyability as way to enforce unique ownership of an
+    //      external resource in the typesystem. The fork breaks that
+    //      assumption, as now both parent and child process have an
+    //      owned instance of the object that represents the same
+    //      underlying resource.
+    // While these seem like niche problems, (1) in particular is
+    // highly relevant. For example, `malloc()` may grab a mutex internally,
+    // and so, if we forked while another thread was mallocing' and our
+    // pre_exec closure allocates as well, it will block on the malloc
+    // mutex forever

+    // The proper solution is to only use C library functions that are marked
+    // "async-signal-safe": https://man7.org/linux/man-pages/man7/signal-safety.7.html
+    //
+    // With this specific pre_exec() closure, the non-error path doesn't allocate.
+    // The error path uses `anyhow`, and hence does allocate.
+    // We take our chances there, hoping that any potential disaster is constrained
+    // to the child process (e.g., malloc has no state ourside of the child process).

 ## Authentication
 
 ### Overview
+We use JWT tokens in communication between almost all components (compute, pageserver, safekeeper, CLI) regardless of the protocol used (HTTP/PostgreSQL).
+storage_broker currently has no authentication.
+Authentication is optional and is disabled by default for easier debugging.
+It is used in some tests, though.
+Note that we do not cover authentication with `pg.neon.tech` here.
 
-Current state of authentication includes usage of JWT tokens in communication between compute and pageserver and between CLI and pageserver. JWT token is signed using RSA keys. CLI generates a key pair during call to `neon_local init`. Using following openssl commands:
+For HTTP connections we use the Bearer authentication scheme.
+For PostgreSQL connections we expect the token to be passed as a password.
+There is a caveat for `psql`: it silently truncates passwords to 100 symbols, so to correctly pass JWT via `psql` you have to either use `PGPASSWORD` environment variable, or store password in `psql`'s config file.
+
+Current token scopes are described in `utils::auth::Scope`.
+There are no expiration or rotation schemes.
+
+_TODO_: some scopes allow both access to server management API and to the data.
+These probably should be split into multiple scopes.
+
+Tokens should not occur in logs.
+They may sometimes occur in configuration files, although this is discouraged
+because configs may be parsed and dumped into logs.
+
+#### Tokens generation and validation
+JWT tokens are signed using a private key.
+Compute/pageserver/safekeeper use the private key's public counterpart to validate JWT tokens.
+These components should not have access to the private key and may only get tokens from their configuration or external clients. 
+
+The key pair is generated once for an installation of compute/pageserver/safekeeper, e.g. by `neon_local init`.
+There is currently no way to rotate the key without bringing down all components.
+
+### CLI
+CLI generates a key pair during call to `neon_local init` with the following commands:
 
 ```bash
-openssl genrsa -out private_key.pem 2048
-openssl rsa -in private_key.pem -pubout -outform PEM -out public_key.pem
+openssl genrsa -out auth_private_key.pem 2048
+openssl rsa -in auth_private_key.pem -pubout -outform PEM -out auth_public_key.pem
 ```
 
-CLI also generates signed token and saves it in the config for later access to pageserver. Now authentication is optional. Pageserver has two variables in config: `auth_validation_public_key_path` and `auth_type`, so when auth type present and set to `NeonJWT` pageserver will require authentication for connections. Actual JWT is passed in password field of connection string. There is a caveat for psql, it silently truncates passwords to 100 symbols, so to correctly pass JWT via psql you have to either use PGPASSWORD environment variable, or store password in psql config file.
+Configuration files for all components point to `public_key.pem` for JWT validation.
+However, authentication is disabled by default.
+There is no way to automatically enable it everywhere, you have to configure each component individually.
 
-Currently there is no authentication between compute and safekeepers, because this communication layer is under heavy refactoring. After this refactoring support for authentication will be added there too. Now safekeeper supports "hardcoded" token passed via environment variable to be able to use callmemaybe command in pageserver.
+CLI also generates signed token (full access to Pageserver) and saves it in
+the CLI's `config` file under `pageserver.auth_token`.
+Note that pageserver's config does not have any similar parameter.
+CLI is the only component which accesses that token.
+Technically it could generate it from the private key on each run,
+but it does not do that for some reason (_TODO_).
 
-Compute uses token passed via environment variable to communicate to pageserver and in the future to the safekeeper too.
+### Compute
+#### Overview
+Compute is a per-timeline PostgreSQL instance, so it should not have
+any access to data of other tenants.
+All tokens used by a compute are restricted to a specific tenant.
+There is no auth isolation from other timelines of the same tenant,
+but a non-rogue client never accesses another timeline even by an accident:
+timeline IDs are random and hard to guess.
 
-JWT authentication now supports two scopes: tenant and pageserverapi. Tenant scope is intended for use in tenant related api calls, e.g. create_branch. Compute launched for particular tenant also uses this scope. Scope pageserver api is intended to be used by console to manage pageserver. For now we have only one management operation - create tenant.
+#### Incoming connections
+All incoming connections are from PostgreSQL clients.
+Their authentication is just plain PostgreSQL authentication and out of scope for this document.
 
-Examples for token generation in python:
+There is no administrative API except those provided by PostgreSQL.
+
+#### Outgoing connections
+Compute connects to Pageserver for getting pages.
+The connection string is configured by the `neon.pageserver_connstring` PostgreSQL GUC, e.g. `postgresql://no_user:$NEON_AUTH_TOKEN@localhost:15028`.
+The environment variable inside the connection string is substituted with
+the JWT token.
+
+Compute connects to Safekeepers to write and commit data.
+The token is the same for all safekeepers.
+It's stored in an environment variable, whose name is configured
+by the `neon.safekeeper_token_env` PostgreSQL GUC.
+If the GUC is unset, no token is passed.
+
+Note that both tokens can be (and typically are) the same;
+the scope is the tenant and the token is usually passed through the
+`$NEON_AUTH_TOKEN` environment variable.
+
+### Pageserver
+#### Overview
+Pageserver keeps track of multiple tenants, each having multiple timelines.
+For each timeline, it connects to the corresponding Safekeeper.
+Information about "corresponding Safekeeper" is published by Safekeepers
+in the storage_broker, but they do not publish access tokens, otherwise what is
+the point of authentication.
+
+Pageserver keeps a connection to some set of Safekeepers, which
+may or may not correspond to active Computes.
+Hence, we cannot obtain a per-timeline access token from a Compute.
+E.g. if the timeline's Compute terminates before all WAL is
+consumed by the Pageserver, the Pageserver continues consuming WAL.
+
+Pageserver replicas' authentication is the same as the main's.
+
+#### Incoming connections
+Pageserver listens for connections from computes.
+Each compute should present a token valid for the timeline's tenant.
+
+Pageserver also has HTTP API: some parts are per-tenant,
+some parts are server-wide, these are different scopes.
+
+The `auth_type` configuration variable in Pageserver's config may have
+either of three values:
+
+* `Trust` removes all authentication. The outdated `MD5` value does likewise
+* `NeonJWT` enables JWT validation.
+   Tokens are validated using the public key which lies in a PEM file
+   specified in the `auth_validation_public_key_path` config.
+
+#### Outgoing connections
+Pageserver makes a connection to a Safekeeper for each active timeline.
+As Pageserver may want to access any timeline it has on the disk,
+it is given a blanket JWT token to access any data on any Safekeeper.
+This token is passed through an environment variable called `NEON_AUTH_TOKEN`
+(non-configurable as of writing this text).
+
+A better way _may be_ to store JWT token for each timeline next to it,
+but may be not.
+
+### Safekeeper
+#### Overview
+Safekeeper keeps track of multiple tenants, each having multiple timelines.
+
+#### Incoming connections
+Safekeeper accepts connections from Compute/Pageserver, each
+connection corresponds to a specific timeline and requires
+a corresponding JWT token.
+
+Safekeeper also has HTTP API: some parts are per-tenant,
+some parts are server-wide, these are different scopes.
+
+The `auth-validation-public-key-path` command line options controls
+the authentication mode:
+
+* If the option is missing, there is no authentication or JWT token validation.
+* If the option is present, it should be a path to the public key PEM file used for JWT token validation.
+
+#### Outgoing connections
+No connections are initiated by a Safekeeper.
+
+### In the source code
+Tests do not use authentication by default.
+If you need it, you can enable it by configuring the test's environment:
 
 ```python
-# generate pageserverapi token
-management_token = jwt.encode({"scope": "pageserverapi"}, auth_keys.priv, algorithm="RS256")
-
-# generate tenant token
-tenant_token = jwt.encode({"scope": "tenant", "tenant_id": ps.initial_tenant}, auth_keys.priv, algorithm="RS256")
+neon_env_builder.auth_enabled = True
 ```
 
-Utility functions to work with jwts in rust are located in libs/utils/src/auth.rs
+You will have to generate tokens if you want to access components inside the test directly,
+use `AuthKeys.generate_*_token` methods for that.
+If you create a new scope, please create a new method to prevent mistypes in scope's name.

+### Overview
+Pageserver and proxy periodically collect consumption metrics and push them to a HTTP endpoint.
+
+This doc describes current implementation details.
+For design details see [the RFC](./rfcs/021-metering.md) and [the discussion on Github](https://github.com/neondatabase/neon/pull/2884).
+
+- The metrics are collected in a separate thread, and the collection interval and endpoint are configurable.
+
+- Metrics are cached, so that we don't send unchanged metrics on every iteration.
+
+- Metrics are sent in batches of 1000 (see CHUNK_SIZE const) metrics max with no particular grouping guarantees.
+
+batch format is
+```json
+
+{ "events" : [metric1, metric2, ...]]}
+
+```
+See metric format examples below.
+
+- All metrics values are in bytes, unless otherwise specified.
+
+- Currently no retries are implemented.
+
+### Pageserver metrics
+
+#### Configuration
+The endpoint and the collection interval are specified in the pageserver config file (or can be passed as command line arguments):
+`metric_collection_endpoint` defaults to None, which means that metric collection is disabled by default.
+`metric_collection_interval` defaults to 10min
+
+#### Metrics
+
+Currently, the following metrics are collected:
+
+- `written_size`
+
+Amount of WAL produced , by a timeline, i.e. last_record_lsn
+This is an absolute, per-timeline metric.
+
+- `resident_size`
+
+Size of all the layer files in the tenant's directory on disk on the pageserver.
+This is an absolute, per-tenant metric.
+
+- `remote_storage_size`
+
+Size of the remote storage (S3) directory.
+This is an absolute, per-tenant metric.
+
+- `timeline_logical_size`
+Logical size of the data in the timeline
+This is an absolute, per-timeline metric.
+
+- `synthetic_storage_size`
+Size of all tenant's branches including WAL
+This is the same metric that `tenant/{tenant_id}/size` endpoint returns.
+This is an absolute, per-tenant metric.
+
+Synthetic storage size is calculated in a separate thread, so it might be slightly outdated.
+
+#### Format example
+
+```json
+{
+"metric": "remote_storage_size",
+"type": "absolute",
+"time": "2022-12-28T11:07:19.317310284Z",
+"idempotency_key": "2022-12-28 11:07:19.317310324 UTC-1-4019",
+"value": 12345454,
+"tenant_id": "5d07d9ce9237c4cd845ea7918c0afa7d",
+"timeline_id": "a03ebb4f5922a1c56ff7485cc8854143",
+}
+```
+
+`idempotency_key` is a unique key for each metric, so that we can deduplicate metrics.
+It is a combination of the time, node_id and a random number.
+
+### Proxy consumption metrics
+
+#### Configuration
+The endpoint and the collection interval can be passed as command line arguments for proxy:
+`metric_collection_endpoint` no default, which means that metric collection is disabled by default.
+`metric_collection_interval` no default
+
+#### Metrics
+
+Currently, only one proxy metric is collected:
+
+- `proxy_io_bytes_per_client`
+Outbound traffic per client.
+This is an incremental, per-endpoint metric.
+
+#### Format example
+
+```json
+{
+"metric": "proxy_io_bytes_per_client",
+"type": "incremental",
+"start_time": "2022-12-28T11:07:19.317310284Z",
+"stop_time": "2022-12-28T11:07:19.317310284Z",
+"idempotency_key": "2022-12-28 11:07:19.317310324 UTC-1-4019",
+"value": 12345454,
+"endpoint_id": "5d07d9ce9237c4cd845ea7918c0afa7d",
+}
+```
+
+The metric is incremental, so the value is the difference between the current and the previous value.
+If there is no previous value, the value, the value is the current value and the `start_time` equals `stop_time`.
+
+### TODO
+
+- [ ] Handle errors better: currently if one tenant fails to gather metrics, the whole iteration fails and metrics are not sent for any tenant.
+- [ ] Add retries
+- [ ] Tune the interval

+# Error handling and logging
+
+## Logging errors
+
+The principle is that errors are logged when they are handled. If you
+just propagate an error to the caller in a function, you don't need to
+log it; the caller will. But if you consume an error in a function,
+you *must* log it (if it needs to be logged at all).
+
+For example:
+
+```rust
+fn read_motd_file() -> std::io::Result<String> {
+    let mut f = File::open("/etc/motd")?;
+    let mut result = String::new();
+    f.read_to_string(&mut result)?;
+    result
+}
+```
+
+Opening or reading the file could fail, but there is no need to log
+the error here. The function merely propagates the error to the
+caller, and it is up to the caller to log the error or propagate it
+further, if the failure is not expected. But if, for example, it is
+normal that the "/etc/motd" file doesn't exist, the caller can choose
+to silently ignore the error, or log it as an INFO or DEBUG level
+message:
+
+```rust
+fn get_message_of_the_day() -> String {
+    // Get the motd from /etc/motd, or return the default proverb
+    match read_motd_file() {
+        Ok(motd) => motd,
+        Err(err)  => {
+            // It's normal that /etc/motd doesn't exist, but if we fail to
+            // read it for some other reason, that's unexpected. The message
+            // of the day isn't very important though, so we just WARN and
+            // continue with the default in any case.
+            if err.kind() != std::io::ErrorKind::NotFound {
+                 tracing::warn!("could not read \"/etc/motd\": {err:?}");
+            }
+            "An old error is always more popular than a new truth. - German proverb"
+        }
+    }
+}
+```
+
+## Error types
+
+We use the `anyhow` crate widely. It contains many convenient macros
+like `bail!` and `ensure!` to construct and return errors, and to
+propagate many kinds of low-level errors, wrapped in `anyhow::Error`.
+
+A downside of `anyhow::Error` is that the caller cannot distinguish
+between different error cases. Most errors are propagated all the way
+to the mgmt API handler function, or the main loop that handles a
+connection with the compute node, and they are all handled the same
+way: the error is logged and returned to the client as an HTTP or
+libpq error.
+
+But in some cases, we need to distinguish between errors and handle
+them differently. For example, attaching a tenant to the pageserver
+could fail either because the tenant has already been attached, or
+because we could not load its metadata from cloud storage. The first
+case is more or less expected. The console sends the Attach request to
+the pageserver, and the pageserver completes the operation, but the
+network connection might be lost before the console receives the
+response. The console will retry the operation in that case, but the
+tenant has already been attached. It is important that the pagserver
+responds with the HTTP 403 Already Exists error in that case, rather
+than a generic HTTP 500 Internal Server Error.
+
+If you need to distinguish between different kinds of errors, create a
+new `Error` type. The `thiserror` crate is useful for that. But in
+most cases `anyhow::Error` is good enough.
+
+## Panics
+
+Depending on where a panic happens, it can cause the whole pageserver
+or safekeeper to restart, or just a single tenant. In either case,
+that is pretty bad and causes an outage. Avoid panics. Never use
+`unwrap()` or other calls that might panic, to verify inputs from the
+network or from disk.
+
+It is acceptable to use functions that might panic, like `unwrap()`, if
+it is obvious that it cannot panic. For example, if you have just
+checked that a variable is not None, it is OK to call `unwrap()` on it,
+but it is still preferable to use `expect("reason")` instead to explain
+why the function cannot fail.
+
+`assert!` and `panic!` are reserved for checking clear invariants and
+very obvious "can't happen" cases. When in doubt, use anyhow `ensure!`
+or `bail!` instead.
+
+## Error levels
+
+`tracing::Level` doesn't provide very clear guidelines on what the
+different levels mean, or when to use which level. Here is how we use
+them:
+
+### Error
+
+Examples:
+- could not open file "foobar"
+- invalid tenant id
+
+Errors are not expected to happen during normal operation. Incorrect
+inputs from client can cause ERRORs. For example, if a client tries to
+call a mgmt API that doesn't exist, or if a compute node sends passes
+an LSN that has already been garbage collected away.
+
+These should *not* happen during normal operations. "Normal
+operations" is not a very precise concept. But for example, disk
+errors are not expected to happen when the system is working, so those
+count as Errors. However, if a TCP connection to a compute node is
+lost, that is not considered an Error, because it doesn't affect the
+pageserver's or safekeeper's operation in any way, and happens fairly
+frequently when compute nodes are shut down, or are killed abruptly
+because of errors in the compute.
+
+**Errors are monitored, and always need human investigation to determine
+the cause.**
+
+Whether something should be logged at ERROR, WARNING or INFO level can
+depend on the callers and clients. For example, it might be unexpected
+and a sign of a serious issue if the console calls the
+"timeline_detail" mgmt API for a timeline that doesn't exist. ERROR
+would be appropriate in that case. But if the console routinely calls
+the API after deleting a timeline, to check if the deletion has
+completed, then it would be totally normal and an INFO or DEBUG level
+message would be more appropriate. If a message is logged as an ERROR,
+but it in fact happens frequently in production and never requires any
+action, it should probably be demoted to an INFO level message.
+
+### Warn
+
+Examples:
+- could not remove temporary file "foobar.temp"
+- unrecognized file "foobar" in timeline directory
+
+Warnings are similar to Errors, in that they should not happen
+when the system is operating normally. The difference between Error and
+Warning is that an Error means that the operation failed, whereas Warning
+means that something unexpected happened, but the operation continued anyway.
+For example, if deleting a file fails because the file already didn't exist,
+it should be logged as Warning.
+
+> **Note:** The python regression tests, under `test_regress`, check the
+> pageserver log after each test for any ERROR and WARN lines. If there are
+> any ERRORs or WARNs that have not been explicitly listed in the test as
+> allowed, the test is marked a failed. This is to catch unexpected errors
+> e.g. in background operations, that don't cause immediate misbehaviour in
+> the tested functionality.
+
+### Info
+
+Info level is used to log useful information when the system is
+operating normally. Info level is appropriate e.g. for logging state
+changes, background operations, and network connections.
+
+Examples:
+- "system is shutting down"
+- "tenant was created"
+- "retrying S3 upload"
+
+### Debug & Trace
+
+Debug and Trace level messages are not printed to the log in our normal
+production configuration, but could be enabled for a specific server or
+tenant, to aid debugging. (Although we don't actually have that
+capability as of this writing).
+
+## Context
+
+We use logging "spans" to hold context information about the current
+operation. Almost every operation happens on a particular tenant and
+timeline, so we enter a span with the "tenant_id" and "timeline_id"
+very early when processing an incoming API request, for example. All
+background operations should also run in a span containing at least
+those two fields, and any other parameters or information that might
+be useful when debugging an error that might happen when performing
+the operation.
+
+TODO: Spans are not captured in the Error when it is created, but when
+the error is logged. It would be more useful to capture them at Error
+creation. We should consider using `tracing_error::SpanTrace` to do
+that.
+
+## Error message style
+
+PostgreSQL has a style guide for writing error messages:
+
+https://www.postgresql.org/docs/current/error-style-guide.html
+
+Follow that guide when writing error messages in the PostgreSQL
+extension. We don't follow it strictly in the pageserver and
+safekeeper, but the advice in the PostgreSQL style guide is generally
+good, and you can't go wrong by following it.
