Set version to 2.3.0-rc1

* 2.2.2 changed functions acquireAsync and NetworkOPsImp::recvValidation to add an item to a collection under lock, unlock, do some work, then lock again to do remove the item. It will deadlock if an exception is thrown while adding the item - before unlocking.
* Replace ScopedUnlock with scope_unlock.

 For a log of breaking changes, see the **API Version [number]** headings. In general, breaking changes are associated with a particular API Version number. For non-breaking changes, scroll to the **XRP Ledger version [x.y.z]** headings. Non-breaking changes are associated with a particular XRP Ledger (`rippled`) release.
 
+## API Version 2
+
+API version 2 is available in `rippled` version 2.0.0 and later. To use this API, clients specify `"api_version" : 2` in each request.
+
+#### Removed methods
+
+In API version 2, the following deprecated methods are no longer available: (https://github.com/XRPLF/rippled/pull/4759)
+
+- `tx_history` - Instead, use other methods such as `account_tx` or `ledger` with the `transactions` field set to `true`.
+- `ledger_header` - Instead, use the `ledger` method.
+
+#### Modifications to JSON transaction element in V2
+
+In API version 2, JSON elements for transaction output have been changed and made consistent for all methods which output transactions. (https://github.com/XRPLF/rippled/pull/4775)
+This helps to unify the JSON serialization format of transactions. (https://github.com/XRPLF/clio/issues/722, https://github.com/XRPLF/rippled/issues/4727)
+
+- JSON transaction element is named `tx_json`
+- Binary transaction element is named `tx_blob`
+- JSON transaction metadata element is named `meta`
+- Binary transaction metadata element is named `meta_blob`
+
+Additionally, these elements are now consistently available next to `tx_json` (i.e. sibling elements), where possible:
+
+- `hash` - Transaction ID. This data was stored inside transaction output in API version 1, but in API version 2 is a sibling element.
+- `ledger_index` - Ledger index (only set on validated ledgers)
+- `ledger_hash` - Ledger hash (only set on closed or validated ledgers)
+- `close_time_iso` - Ledger close time expressed in ISO 8601 time format (only set on validated ledgers)
+- `validated` - Bool element set to `true` if the transaction is in a validated ledger, otherwise `false`
+
+This change affects the following methods:
+
+- `tx` - Transaction data moved into element `tx_json` (was inline inside `result`) or, if binary output was requested, moved from `tx` to `tx_blob`. Renamed binary transaction metadata element (if it was requested) from `meta` to `meta_blob`. Changed location of `hash` and added new elements
+- `account_tx` - Renamed transaction element from `tx` to `tx_json`. Renamed binary transaction metadata element (if it was requested) from `meta` to `meta_blob`. Changed location of `hash` and added new elements
+- `transaction_entry` - Renamed transaction metadata element from `metadata` to `meta`. Changed location of `hash` and added new elements
+- `subscribe` - Renamed transaction element from `transaction` to `tx_json`. Changed location of `hash` and added new elements
+- `sign`, `sign_for`, `submit` and `submit_multisigned` - Changed location of `hash` element.
+
+#### Modification to `Payment` transaction JSON schema
+
+When reading Payments, the `Amount` field should generally **not** be used. Instead, use [delivered_amount](https://xrpl.org/partial-payments.html#the-delivered_amount-field) to see the amount that the Payment delivered. To clarify its meaning, the `Amount` field is being renamed to `DeliverMax`. (https://github.com/XRPLF/rippled/pull/4733)
+
+- In `Payment` transaction type, JSON RPC field `Amount` is renamed to `DeliverMax`. To enable smooth client transition, `Amount` is still handled, as described below: (https://github.com/XRPLF/rippled/pull/4733)
+  - On JSON RPC input (e.g. `submit_multisigned` etc. methods), `Amount` is recognized as an alias to `DeliverMax` for both API version 1 and version 2 clients.
+  - On JSON RPC input, submitting both `Amount` and `DeliverMax` fields is allowed _only_ if they are identical; otherwise such input is rejected with `rpcINVALID_PARAMS` error.
+  - On JSON RPC output (e.g. `subscribe`, `account_tx` etc. methods), `DeliverMax` is present in both API version 1 and version 2.
+  - On JSON RPC output, `Amount` is only present in API version 1 and _not_ in version 2.
+
+#### Modifications to account_info response
+
+- `signer_lists` is returned in the root of the response. (In API version 1, it was nested under `account_data`.) (https://github.com/XRPLF/rippled/pull/3770)
+- When using an invalid `signer_lists` value, the API now returns an "invalidParams" error. (https://github.com/XRPLF/rippled/pull/4585)
+  - (`signer_lists` must be a boolean. In API version 1, strings were accepted and may return a normal response - i.e. as if `signer_lists` were `true`.)
+
+#### Modifications to [account_tx](https://xrpl.org/account_tx.html#account_tx) response
+
+- Using `ledger_index_min`, `ledger_index_max`, and `ledger_index` returns `invalidParams` because if you use `ledger_index_min` or `ledger_index_max`, then it does not make sense to also specify `ledger_index`. In API version 1, no error was returned. (https://github.com/XRPLF/rippled/pull/4571)
+  - The same applies for `ledger_index_min`, `ledger_index_max`, and `ledger_hash`. (https://github.com/XRPLF/rippled/issues/4545#issuecomment-1565065579)
+- Using a `ledger_index_min` or `ledger_index_max` beyond the range of ledgers that the server has:
+  - returns `lgrIdxMalformed` in API version 2. Previously, in API version 1, no error was returned. (https://github.com/XRPLF/rippled/issues/4288)
+- Attempting to use a non-boolean value (such as a string) for the `binary` or `forward` parameters returns `invalidParams` (`rpcINVALID_PARAMS`). Previously, in API version 1, no error was returned. (https://github.com/XRPLF/rippled/pull/4620)
+
+#### Modifications to [noripple_check](https://xrpl.org/noripple_check.html#noripple_check) response
+
+- Attempting to use a non-boolean value (such as a string) for the `transactions` parameter returns `invalidParams` (`rpcINVALID_PARAMS`). Previously, in API version 1, no error was returned. (https://github.com/XRPLF/rippled/pull/4620)
+
 ## API Version 1
 
-This version is supported by all `rippled` versions. At time of writing, it is the default API version, used when no `api_version` is specified. When a new API version is introduced, the command line interface will default to the latest API version. The command line is intended for ad-hoc usage by humans, not programs or automated scripts. The command line is not meant for use in production code.
+This version is supported by all `rippled` versions. For WebSocket and HTTP JSON-RPC requests, it is currently the default API version used when no `api_version` is specified.
 
-### Idiosyncrasies
+The [commandline](https://xrpl.org/docs/references/http-websocket-apis/api-conventions/request-formatting/#commandline-format) always uses the latest API version. The command line is intended for ad-hoc usage by humans, not programs or automated scripts. The command line is not meant for use in production code.
 
-#### V1 account_info response
+### Inconsistency: server_info - network_id
 
-In [the response to the `account_info` command](https://xrpl.org/account_info.html#response-format), there is `account_data` - which is supposed to be an `AccountRoot` object - and `signer_lists` is returned in this object. However, the docs say that `signer_lists` should be at the root level of the reponse.
+The `network_id` field was added in the `server_info` response in version 1.5.0 (2019), but it is not returned in [reporting mode](https://xrpl.org/rippled-server-modes.html#reporting-mode). However, use of reporting mode is now discouraged, in favor of using [Clio](https://github.com/XRPLF/clio) instead.
 
-It makes sense for `signer_lists` to be at the root level because signer lists are not part of the AccountRoot object. (First reported in [xrpl-dev-portal#938](https://github.com/XRPLF/xrpl-dev-portal/issues/938).)
+## XRP Ledger server version 2.2.0
 
-In `api_version: 2`, the `signer_lists` field [will be moved](#modifications-to-account_info-response-in-v2) to the root level of the account_info response. (https://github.com/XRPLF/rippled/pull/3770)
+The following is a non-breaking addition to the API.
 
-#### server_info - network_id
+- The `feature` method now has a non-admin mode for users. (It was previously only available to admin connections.) The method returns an updated list of amendments, including their names and other information. ([#4781](https://github.com/XRPLF/rippled/pull/4781))
 
-The `network_id` field was added in the `server_info` response in version 1.5.0 (2019), but it is not returned in [reporting mode](https://xrpl.org/rippled-server-modes.html#reporting-mode).
+### Breaking change in 2.3
 
-## XRP Ledger server version 2.0.0
+- `book_changes`: If the requested ledger version is not available on this node, a `ledgerNotFound` error is returned and the node does not attempt to acquire the ledger from the p2p network (as with other non-admin RPCs).
 
-### Additions in 2.2
+Admins can still attempt to retrieve old ledgers with the `ledger_request` RPC.
 
-Additions are intended to be non-breaking (because they are purely additive).
+### Addition in 2.3
 
-- `feature`: A non-admin mode that uses the same formatting as admin RPC, but hides potentially-sensitive data.
+- `book_changes`: Returns a `validated` field in its response, which was missing in prior versions.
 
-### Additions in 2.0
-
-Additions are intended to be non-breaking (because they are purely additive).
+The following additions are non-breaking (because they are purely additive).
 
 - `server_definitions`: A new RPC that generates a `definitions.json`-like output that can be used in XRPL libraries.
 - In `Payment` transactions, `DeliverMax` has been added. This is a replacement for the `Amount` field, which should not be used.

+[Version 1.12.0](https://github.com/XRPLF/rippled/releases/tag/1.12.0) was released on Sep 6, 2023. The following additions are non-breaking (because they are purely additive).
 
 - `server_info`: Added `ports`, an array which advertises the RPC and WebSocket ports. This information is also included in the `/crawl` endpoint (which calls `server_info` internally). `grpc` and `peer` ports are also included. (https://github.com/XRPLF/rippled/pull/4427)
   - `ports` contains objects, each containing a `port` for the listening port (a number string), and a `protocol` array listing the supported protocols on that port.

-## API Version 2
-
-API version 2 is introduced in `rippled` version 2.0. Users can request it explicitly by specifying `"api_version" : 2`.
-
-#### Removed methods
-
-In API version 2, the following deprecated methods are no longer available: (https://github.com/XRPLF/rippled/pull/4759)
-
-- `tx_history` - Instead, use other methods such as `account_tx` or `ledger` with the `transactions` field set to `true`.
-- `ledger_header` - Instead, use the `ledger` method.
-
-#### Modifications to JSON transaction element in V2
-
-In API version 2, JSON elements for transaction output have been changed and made consistent for all methods which output transactions. (https://github.com/XRPLF/rippled/pull/4775)
-This helps to unify the JSON serialization format of transactions. (https://github.com/XRPLF/clio/issues/722, https://github.com/XRPLF/rippled/issues/4727)
-
-- JSON transaction element is named `tx_json`
-- Binary transaction element is named `tx_blob`
-- JSON transaction metadata element is named `meta`
-- Binary transaction metadata element is named `meta_blob`
-
-Additionally, these elements are now consistently available next to `tx_json` (i.e. sibling elements), where possible:
-
-- `hash` - Transaction ID. This data was stored inside transaction output in API version 1, but in API version 2 is a sibling element.
-- `ledger_index` - Ledger index (only set on validated ledgers)
-- `ledger_hash` - Ledger hash (only set on closed or validated ledgers)
-- `close_time_iso` - Ledger close time expressed in ISO 8601 time format (only set on validated ledgers)
-- `validated` - Bool element set to `true` if the transaction is in a validated ledger, otherwise `false`
-
-This change affects the following methods:
-
-- `tx` - Transaction data moved into element `tx_json` (was inline inside `result`) or, if binary output was requested, moved from `tx` to `tx_blob`. Renamed binary transaction metadata element (if it was requested) from `meta` to `meta_blob`. Changed location of `hash` and added new elements
-- `account_tx` - Renamed transaction element from `tx` to `tx_json`. Renamed binary transaction metadata element (if it was requested) from `meta` to `meta_blob`. Changed location of `hash` and added new elements
-- `transaction_entry` - Renamed transaction metadata element from `metadata` to `meta`. Changed location of `hash` and added new elements
-- `subscribe` - Renamed transaction element from `transaction` to `tx_json`. Changed location of `hash` and added new elements
-- `sign`, `sign_for`, `submit` and `submit_multisigned` - Changed location of `hash` element.
-
-#### Modification to `Payment` transaction JSON schema
-
-When reading Payments, the `Amount` field should generally **not** be used. Instead, use [delivered_amount](https://xrpl.org/partial-payments.html#the-delivered_amount-field) to see the amount that the Payment delivered. To clarify its meaning, the `Amount` field is being renamed to `DeliverMax`. (https://github.com/XRPLF/rippled/pull/4733)
-
-- In `Payment` transaction type, JSON RPC field `Amount` is renamed to `DeliverMax`. To enable smooth client transition, `Amount` is still handled, as described below: (https://github.com/XRPLF/rippled/pull/4733)
-  - On JSON RPC input (e.g. `submit_multisigned` etc. methods), `Amount` is recognized as an alias to `DeliverMax` for both API version 1 and version 2 clients.
-  - On JSON RPC input, submitting both `Amount` and `DeliverMax` fields is allowed _only_ if they are identical; otherwise such input is rejected with `rpcINVALID_PARAMS` error.
-  - On JSON RPC output (e.g. `subscribe`, `account_tx` etc. methods), `DeliverMax` is present in both API version 1 and version 2.
-  - On JSON RPC output, `Amount` is only present in API version 1 and _not_ in version 2.
-
-#### Modifications to account_info response
-
-- `signer_lists` is returned in the root of the response. In API version 1, it was nested under `account_data`. (https://github.com/XRPLF/rippled/pull/3770)
-- When using an invalid `signer_lists` value, the API now returns an "invalidParams" error. (https://github.com/XRPLF/rippled/pull/4585)
-  - (`signer_lists` must be a boolean. In API version 1, strings were accepted and may return a normal response - i.e. as if `signer_lists` were `true`.)
-
-#### Modifications to [account_tx](https://xrpl.org/account_tx.html#account_tx) response
-
-- Using `ledger_index_min`, `ledger_index_max`, and `ledger_index` returns `invalidParams` because if you use `ledger_index_min` or `ledger_index_max`, then it does not make sense to also specify `ledger_index`. In API version 1, no error was returned. (https://github.com/XRPLF/rippled/pull/4571)
-  - The same applies for `ledger_index_min`, `ledger_index_max`, and `ledger_hash`. (https://github.com/XRPLF/rippled/issues/4545#issuecomment-1565065579)
-- Using a `ledger_index_min` or `ledger_index_max` beyond the range of ledgers that the server has:
-  - returns `lgrIdxMalformed` in API version 2. Previously, in API version 1, no error was returned. (https://github.com/XRPLF/rippled/issues/4288)
-- Attempting to use a non-boolean value (such as a string) for the `binary` or `forward` parameters returns `invalidParams` (`rpcINVALID_PARAMS`). Previously, in API version 1, no error was returned. (https://github.com/XRPLF/rippled/pull/4620)
-
-#### Modifications to [noripple_check](https://xrpl.org/noripple_check.html#noripple_check) response
-
-- Attempting to use a non-boolean value (such as a string) for the `transactions` parameter returns `invalidParams` (`rpcINVALID_PARAMS`). Previously, in API version 1, no error was returned. (https://github.com/XRPLF/rippled/pull/4620)

@@ -73,27 +73,235 @@ The source must be formatted according to the style guide below.
 
 Header includes must be [levelized](./Builds/levelization).
 
+Changes should be usually squashed down into a single commit.
+Some larger or more complicated change sets make more sense,
+and are easier to review if organized into multiple logical commits.
+Either way, all commits should fit the following criteria:
+* Changes should be presented in a single commit or a logical
+  sequence of commits.
+  Specifically, chronological commits that simply
+  reflect the history of how the author implemented
+  the change, "warts and all", are not useful to
+  reviewers.
+* Every commit should have a [good message](#good-commit-messages).
+  to explain a specific aspects of the change.
+* Every commit should be signed.
+* Every commit should be well-formed (builds successfully,
+  unit tests passing), as this helps to resolve merge
+  conflicts, and makes it easier to use `git bisect`
+  to find bugs.
+
+### Good commit messages
+
+Refer to
+["How to Write a Git Commit Message"](https://cbea.ms/git-commit/)
+for general rules on writing a good commit message.
+
+In addition to those guidelines, please add one of the following
+prefixes to the subject line if appropriate.
+* `fix:` - The primary purpose is to fix an existing bug.
+* `perf:` - The primary purpose is performance improvements.
+* `refactor:` - The changes refactor code without affecting
+  functionality.
+* `test:` - The changes _only_ affect unit tests.
+* `docs:` - The changes _only_ affect documentation. This can
+  include code comments in addition to `.md` files like this one.
+* `build:` - The changes _only_ affect the build process,
+  including CMake and/or Conan settings.
+* `chore:` - Other tasks that don't affect the binary, but don't fit
+  any of the other cases. e.g. formatting, git settings, updating
+  Github Actions jobs.
+
+Whenever possible, when updating commits after the PR is open, please
+add the PR number to the end of the subject line. e.g. `test: Add
+unit tests for Feature X (#1234)`.
 
 ## Pull requests
 
 In general, pull requests use `develop` as the base branch.
-
 (Hotfixes are an exception.)
 
-Changes to pull requests must be added as new commits.
-Once code reviewers have started looking at your code, please avoid
-force-pushing a branch in a pull request.
+If your changes are not quite ready, but you want to make it easily available
+for preliminary examination or review, you can create a "Draft" pull request.
+While a pull request is marked as a "Draft", you can rebase or reorganize the
+commits in the pull request as desired.
+
+Github pull requests are created as "Ready" by default, or you can mark
+a "Draft" pull request as "Ready".
+Once a pull request is marked as "Ready",
+any changes must be added as new commits. Do not
+force-push to a branch in a pull request under review.
+(This includes rebasing your branch onto the updated base branch.
+Use a merge operation, instead or hit the "Update branch" button
+at the bottom of the Github PR page.)
 This preserves the ability for reviewers to filter changes since their last
 review.
 
-A pull request must obtain **approvals from at least two reviewers** before it
-can be considered for merge by a Maintainer.
+A pull request must obtain **approvals from at least two reviewers**
+before it can be considered for merge by a Maintainer.
 Maintainers retain discretion to require more approvals if they feel the
 credibility of the existing approvals is insufficient.
 
 Pull requests must be merged by [squash-and-merge][2]
 to preserve a linear history for the `develop` branch.
 
+### When and how to merge pull requests
+
+#### "Passed"
+
+A pull request should only have the "Passed" label added when it
+meets a few criteria:
+
+1. It must have two approving reviews [as described
+   above](#pull-requests). (Exception: PRs that are deemed "trivial"
+   only need one approval.)
+2. All CI checks must be complete and passed. (One-off failures may
+   be acceptable if they are related to a known issue.)
+3. The PR must have a [good commit message](#good-commit-messages).
+   * If the PR started with a good commit message, and it doesn't
+     need to be updated, the author can indicate that in a comment.
+   * Any contributor, preferably the author, can leave a comment
+     suggesting a commit message.
+   * If the author squashes and rebases the code in preparation for
+     merge, they should also ensure the commit message(s) are updated
+     as well.
+4. The PR branch must be up to date with the base branch (usually
+   `develop`). This is usually accomplised by merging the base branch
+   into the feature branch, but if the other criteria are met, the
+   changes can be squashed and rebased on top of the base branch.
+5. Finally, and most importantly, the author of the PR must
+   positively indicate that the PR is ready to merge. That can be
+   accomplished by adding the "Passed" label if their role allows,
+   or by leaving a comment to the effect that the PR is ready to
+   merge.
+
+Once the "Passed" label is added, a maintainer may merge the PR at
+any time, so don't use it lightly.
+
+#### Instructions for maintainers
+
+The maintainer should double-check that the PR has met all the
+necessary criteria, and can request additional information from the
+owner, or additional reviews, and can always feel free to remove the
+"Passed" label if appropriate. The maintainer has final say on
+whether a PR gets merged, and are encouraged to communicate and
+issues or concerns to other maintainers.
+
+##### Most pull requests: "Squash and merge"
+
+Most pull requests don't need special handling, and can simply be
+merged using the "Squash and merge" button on the Github UI. Update
+the suggested commit message if necessary.
+
+##### Slightly more complicated pull requests
+
+Some pull requests need to be pushed to `develop` as more than one
+commit. There are multiple ways to accomplish this. If the author
+describes a process, and it is reasonable, follow it. Otherwise, do
+a fast forward only merge (`--ff-only`) on the command line and push.
+
+Either way, check that:
+* The commits are based on the current tip of `develop`.
+* The commits are clean: No merge commits (except when reverse
+  merging), no "[FOLD]" or "fixup!" messages.
+* All commits are signed. If the commits are not signed by the author, use
+  `git commit --amend -S` to sign them yourself.
+* At least one (but preferably all) of the commits has the PR number
+  in the commit message.
+
+**Never use the "Create a merge commit" or "Rebase and merge"
+ functions!**
+
+##### Releases, release candidates, and betas
+
+All releases, including release candidates and betas, are handled
+differently from typical PRs. Most importantly, never use
+the Github UI to merge a release.
+
+1. There are two possible conditions that the `develop` branch will
+   be in when preparing a release.
+   1. Ready or almost ready to go: There may be one or two PRs that
+      need to be merged, but otherwise, the only change needed is to
+      update the version number in `BuildInfo.cpp`. In this case,
+      merge those PRs as appropriate, updating the second one, and
+      waiting for CI to finish in between. Then update
+      `BuildInfo.cpp`.
+   2. Several pending PRs: In this case, do not use the Github UI,
+      because the delays waiting for CI in between each merge will be
+      unnecessarily onerous. Instead, create a working branch (e.g.
+      `develop-next`) based off of `develop`. Squash the changes
+      from each PR onto the branch, one commit each (unless
+      more are needed), being sure to sign each commit and update
+      the commit message to include the PR number. You may be able
+      to use a fast-forward merge for the first PR. The workflow may
+      look something like:
+```
+git fetch upstream
+git checkout upstream/develop
+git checkout -b develop-next
+# Use -S on the ff-only merge if prbranch1 isn't signed.
+# Or do another branch first.
+git merge --ff-only user1/prbranch1
+git merge --squash user2/prbranch2
+git commit -S
+git merge --squash user3/prbranch3
+git commit -S
+[...]
+git push --set-upstream origin develop-next
+</pre>
+```
+2. Create the Pull Request with `release` as the base branch. If any
+   of the included PRs are still open,
+   [use closing keywords](https://docs.github.com/articles/closing-issues-using-keywords)
+   in the description to ensure they are closed when the code is
+   released. e.g. "Closes #1234"
+3. Instead of the default template, reuse and update the message from
+   the previous release. Include the following verbiage somewhere in
+   the description:
+```
+The base branch is release. All releases (including betas) go in
+release. This PR will be merged with --ff-only (not squashed or
+rebased, and not using the GitHub UI) to both release and develop.
+```
+4. Sign-offs for the three platforms usually occur offline, but at
+   least one approval will be needed on the PR.
+5. Once everything is ready to go, open a terminal, and do the
+   fast-forward merges manually. Do not push any branches until you
+   verify that all of them update correctly.
+```
+git fetch upstream
+git checkout -b upstream--develop -t upstream/develop || git checkout upstream--develop
+git reset --hard upstream/develop
+# develop-next must be signed already!
+git merge --ff-only origin/develop-next
+git checkout -b upstream--release -t upstream/release || git checkout upstream--release
+git reset --hard upstream/release
+git merge --ff-only origin/develop-next
+# Only do these 3 steps if pushing a release. No betas or RCs
+git checkout -b upstream--master -t upstream/master || git checkout upstream--master
+git reset --hard upstream/master
+git merge --ff-only origin/develop-next
+# Check that all of the branches are updated
+git log -1 --oneline
+# The output should look like:
+# 02ec8b7962 (HEAD -> upstream--master, origin/develop-next, upstream--release, upstream--develop, develop-next) Set version to 2.2.0-rc1
+# Note that all of the upstream--develop/release/master are on this commit.
+# (Master will be missing for betas, etc.)
+# Just to be safe, do a dry run first:
+git push --dry-run upstream-push HEAD:develop
+git push --dry-run upstream-push HEAD:release
+# git push --dry-run upstream-push HEAD:master
+# Now push
+git push upstream-push HEAD:develop
+git push upstream-push HEAD:release
+# git push upstream-push HEAD:master
+# Don't forget to tag the release, too.
+git tag <version number>
+git push upstream-push <version number>
+```
+6. Finally
+[create a new release on Github](https://github.com/XRPLF/rippled/releases).

-# 5. Reporting Mode
-#
-#------------
-#
-#   rippled has an optional operating mode called Reporting Mode. In Reporting
-#   Mode, rippled does not connect to the peer to peer network. Instead, rippled
-#   will continuously extract data from one or more rippled servers that are
-#   connected to the peer to peer network (referred to as an ETL source).
-#   Reporting mode servers will forward RPC requests that require access to the
-#   peer to peer network (submit, fee, etc) to an ETL source.
-#
-#   [reporting]  Settings for Reporting Mode. If and only if this section is
-#                present, rippled will start in reporting mode. This section
-#                contains a list of ETL source names, and key-value pairs. The
-#                ETL source names each correspond to a configuration file
-#                section; the names must match exactly. The key-value pairs are
-#                optional.
-#
-#
-#   [<name>]
-#
-#   A series of key/value pairs that specify an ETL source.
-#
-#   source_ip = <IP-address>
-#
-#       Required. IP address of the ETL source. Can also be a DNS record.
-#
-#   source_ws_port = <number>
-#
-#       Required. Port on which ETL source is accepting unencrypted websocket
-#       connections.
-#
-#   source_grpc_port = <number>
-#
-#       Required for ETL. Port on which ETL source is accepting gRPC requests.
-#       If this option is ommitted, this ETL source cannot actually be used for
-#       ETL; the Reporting Mode server can still forward RPCs to this ETL
-#       source, but cannot extract data from this ETL source.
-#
-#
-#   Key-value pairs (all optional):
-#
-#       read_only    Valid values: 0, 1. Default is 0. If set to 1, the server
-#                    will start in strict read-only mode, and will not perform
-#                    ETL. The server will still handle RPC requests, and will
-#                    still forward RPC requests that require access to the p2p
-#                    network.
-#
-#      start_sequence
-#                   Sequence of first ledger to extract if the database is empty.
-#                   ETL extracts ledgers in order. If this setting is absent and
-#                   the database is empty, ETL will start with the next ledger
-#                   validated by the network. If this setting is present and the
-#                   database is not empty, an exception is thrown.
-#
-#     num_markers   Degree of parallelism used during the initial ledger
-#                   download. Only used if the database is empty. Valid values
-#                   are 1-256. A higher degree of parallelism results in a
-#                   faster download, but puts more load on the ETL source.
-#                   Default is 2.
-#
-#   Example:
-#
-#     [reporting]
-#     etl_source1
-#     etl_source2
-#     read_only=0

-#     [reporting]
-#     etl_source1
-#
-#     [etl_source1]
-#     source_ip=1.2.3.4
-#     source_ws_port=6005
-#     source_grpc_port=50051
-#
-#
-#   Notes:
-#
-#   Reporting Mode requires Postgres (instead of SQLite). The Postgres
-#   connection info is specified under the [ledger_tx_tables] config section;
-#   see the Database section for further documentation.
-#
-#   Each ETL source specified must have gRPC enabled (by adding a [port_grpc]
-#   section to the config). It is recommended to add a secure_gateway entry to
-#   the gRPC section, in order to bypass the server's rate limiting.
-#   This section needs to be added to the config of the ETL source, not
-#   the config of the reporting node. In the example below, the
-#   reporting server is running at 127.0.0.1. Multiple IPs can be
-#   specified in secure_gateway via a comma separated list.
