 ## !!!Caution!!!

-As of Jan 2022, the plugin is considered in BETA stage. **DO NOT USE IT for any serious vaults.** **ALWAYS, ALWAYS, backup your vault before using this plugin.**
+**ALWAYS, ALWAYS, backup your vault before using this plugin.**

 ## Features

 - Supports:
-  - Amazon S3 or S3-compatible
+  - Amazon S3 or S3-compatible (Cloudflare R2 / BackBlaze B2 / MinIO / ...)
  - Dropbox
  - OneDrive for personal
  - Webdav
-  - A list of connectable / not-connectable / in-the-plan / never-possible services are noted down [here](./docs/services_connectable_or_not.md).
+  - [Here](./docs/services_connectable_or_not.md) shows more connectable (or not-connectable) services in details.
 - **Obsidian Mobile supported.** Vaults can be synced across mobile and desktop devices with the cloud service as the "broker".
 - **[End-to-end encryption](./docs/encryption.md) supported.** Files would be encrypted using openssl format before being sent to the cloud **if** user specify a password.
 - **Scheduled auto sync supported.** You can also manually trigger the sync using sidebar ribbon, or using the command from the command palette (or even bind the hot key combination to the command then press the hot key combination).
 - **[Minimal Intrusive](./docs/minimal_intrusive_design.md).**

 ## Limitations

- **To support deltions sync, extra metadata will also be uploaded.** See [Minimal Intrusive](./docs/minimal_intrusive_design.md).
- **No Conflict resolution. No content-diff-and-patch algorithm.** All files and folders are compared using their local and remote "last modified time" and those with later "last modified time" wins.
- **Cloud services cost you money.** Always be aware of the costs and pricing.
- **All files or folder starting with `.` (dot) or `_` (underscore) are treated as hidden files, and would NOT be synced.** It's useful if you have some files just staying locally. But this strategy also means that themes / other plugins / settings of this plugin would neither be synced.
+- **Cloud services cost you money.** Always be aware of the costs and pricing. Specifically, all the operations, including but not limited to downloading, uploading, listing all files, calling any api, storage sizes, may or may not cost you money.
 - **Some limitations from the browser environment.** More technical details are [in the doc](./docs/browser_env.md).
+- **You should protect your `data.json` file.** The file contains sensitive information.
+  - It's strongly advised **NOT** to share your `data.json` file to anyone.
+  - It's usually **NOT** a good idea to check the file into version control. By default, the plugin tries to create a `.gitignore` file inside the plugin directory if it doesn't exist, for ignoring `data.json` in the `git` version control. If you know exactly what it means and want to remove the setting, please modify the `.gitignore` file or set it to be empty.

 ### S3

+- Tutorials / Examples:

+  - [MinIO](./docs/remote_services/s3_minio/README.md)
 - Prepare your S3 (-compatible) service information: [endpoint, region](https://docs.aws.amazon.com/general/latest/gr/s3.html), [access key id, secret access key](https://docs.aws.amazon.com/sdk-for-javascript/v3/developer-guide/getting-your-credentials.html), bucket name. The bucket should be empty and solely for syncing a vault.
- Configure (enable) [CORS](https://docs.aws.amazon.com/AmazonS3/latest/userguide/enabling-cors-examples.html) for requests from `app://obsidian.md` and `capacitor://localhost` and `http://localhost`. Full example is [here](./docs/s3_cors_configure.md). It's unfortunately required, because the plugin sends requests from a browser-like envirement. And those addresses are tested and found on desktop and ios and android.
+- If you are using AWS S3, create [policy and user](./docs/remote_services/s3_general/s3_user_policy.md).
+- Very old version of Obsidian needs [configuring CORS](./docs/remote_services/s3_general/s3_cors_configure.md).
 - Download and enable this plugin.
 - Enter your information to the settings of this plugin.
 - If you want to enable end-to-end encryption, also set a password in settings. If you do not specify a password, the files and folders are synced in plain, original content to the cloud.
 - Click the new "circle arrow" icon on the ribbon (the left sidebar), **every time** you want to sync your vault between local and remote. (Or, you could configure auto sync in the settings panel (See next chapter).) While syncing, the icon becomes "two half-circle arrows". Besides clicking the icon on the sidebar ribbon, you can also activate the corresponding command in the command palette.
 - **Be patient while syncing.** Especially in the first-time sync.
+- If you want to sync the files across multiple devices, **your vault name should be the same** while using default settings.

 ### Dropbox

- **This plugin's function for Dropbox is not as mature as functions for S3.**
 - **This plugin is NOT an official Dropbox product.** The plugin just uses Dropbox's public API.
 - After the authorization, the plugin can read your name and email (which cannot be unselected on Dropbox api), and read and write files in your Dropbox's `/Apps/remotely-save` folder.
- If you decide to authorize this plugin to connect to Dropbox, please go to plugin's settings, and choose Dropbox then follow the instructions.

 ### OneDrive for personal

- **This plugin's function for OneDrive is not as mature as functions for S3.**
 - **This plugin is NOT an official Microsoft / OneDrive product.** The plugin just uses Microsoft's [OneDrive's public API](https://docs.microsoft.com/en-us/onedrive/developer/rest-api).
 - This plugin only works for "OneDrive for personal", and not works for "OneDrive for Business" (yet). See [#11](https://github.com/fyears/remotely-save/issues/11) to further details.

+- If you want to sync the files across multiple devices, **your vault name should be the same** while using default settings.

 ### webdav

- **webdav support is considered experimental.**
- Currently only supports BASIC authorization method.
- Currently webdav server has to be enabled CORS for requests from `app://obsidian.md` and `capacitor://localhost` and `http://localhost`, **AND** all webdav HTTP methods, **AND** all webdav headers. These are required, because Obsidian mobile works like a browser and mobile plugins are limited by CORS policies.
-  - Popular software NextCloud, OwnCloud, `rclone serve webdav` do **NOT** enable CORS by default. If you are using any of them, you should evaluate the risk, and find a way to enable CORS, before using this plugin.
-  - The plugin is tested successfully under python package [`wsgidav` (version 4.0)](https://github.com/mar10/wsgidav). See [this issue](https://github.com/mar10/wsgidav/issues/239) for some details.

-To solve the issue, we have some options:
+1. From Obsidian desktop >= 0.13.25 or mobile >= 1.1.1, Obsidian [provides a new API `requiestUrl`](https://forum.obsidian.md/t/obsidian-release-v0-13-25-insider-build/32701), that allows the plugin to fully bypass the CORS issue. As of Mar 2022, the latest public-released Obsidian desktop has supported this API, but the Obsidian mobile still stays in insider.

-1. The server side needs to return the header `Access-Control-Allow-Origin` allowing the origins `app://obsidian.md` and `capacitor://localhost` and `http://localhost`. Sometimes in the future, the header `Access-Control-Expose-Headers` with some values being set might be also needed.
+2. For using this plugin in Obsidian desktop < 0.13.25 or mobile < 1.1.1, we need to configure the server side to return the header `Access-Control-Allow-Origin` allowing the origins `app://obsidian.md` and `capacitor://localhost` and `http://localhost`.

-   However, some cloud services do not allow configuring or exposing these headers. (Notably most public WebDAV services.)

-2. Obsidian implements and exposes a new api helping developers to bypass the CORS policy.
-
-   Currently (as of Feb 2022), an api `request()` indeed exists, but it only deals with text-like data, and does not support binary data or response headers reading yet.

+## Material Source
+
+To apply for the production use of Dropbox API, some descriptions are needed to be submitted to Dropbox. Coincidently, this can also be served as a "readme" to use this plugin with Dropbox.
+
+## Some Backgrounds
+
+1. Obsidian allows users to take notes using markdown files.
+2. The "app", remotely-save. is an unofficial Obsidian plugin, helping users download and upload ("sync") their notes from and to Dropbox.
+3. Technically, remotely-save is developed using web technologies.
+
+## Api Usages
+
+1. remotely-save uses "App folder", to avoid unnecessary accessing users' other files.
+2. remotely-save uses "account_info.read", to get the displayed username, so that users know which of their accounts has been logged in after OAuth steps.
+3. remotely-save uses "files.content.read", so that it can read the "last modified time", and the content of files on Dropbox. Under some conditions, the plugin would download the files. For example, the plugin would compare the last modified timestamps of the file in the local device and that on Dropbox, and if the timestamp on Dropbox is larger, the plugin would download the "newer" file from Dropbox to local.
+4. remotely-save uses "files.content.write", so that it can upload or overwrite the content of files on Dropbox. Under some conditions, the plugin would do that. For example, the plugin would compare the last modified timestamps of the file in the local device and that on Dropbox, and if the timestamp in the local device is larger, the plugin would upload the "newer" file from local to Dropbox, and overwrite that file on Dropbox.

+
+1. Download the note-taking app Obsidian (Windows or Mac versions are both ok) from its official website: https://obsidian.md/ . It's free to download and use. Then install it.
+2. Open Obsidian, click the "Create" button under "Create new vault".
+3. Pick a vault name, "example-vault", and choose a location, then click "Create".
+   ![step03](./attachments/step03.png)
+4. Close any update new if prompted.
+5. Create a new note by clicking a button on the left. And write something on the note.
+   ![step05](./attachments/step05.png)
+6. Click "setting" (a gear icon) on the button left of the sidebar.
+   ![step06](./attachments/step06.png)
+7. In the settings panel, go to the "Community plugins" page, turn off the safe mode, and confirm to turn off the safe mode. Then click the "Browse" button for community plugins.
+   ![step07](./attachments/step07.png)
+8. Search "Remotely Save" and install on the result.
+   ![step08](./attachments/step08.png)
+9. After successful installing the plugin, go back to the "Community plugins" page, and enable the plugin.
+   ![step09](./attachments/step09.png)
+10. Go to newly added "Remotely Save" settings, select "Dropbox" in "Choose service", and click the "Auth" button.
+    ![step10](./attachments/step10.png)
+11. The standard auth flow address is shown, users should click the address, and finish the auth steps on the website. Finally, the Dropbox website should automatically redirect users back to the Obsidian app.
+    ![step11](./attachments/step11.png)
+12. The "Auth" button disappears. A new "Revoke Auth" appears.
+    ![step12](./attachments/step12.png)
+13. Go back to the main interface of Obsidian, a new "switch icon" should appear on the left sidebar. Click this, then the plugin would trigger the sync progress. It would compare meta info of local files and remote files (on Dropbox), and decide to download some files and/or upload some files.
+    ![step13](./attachments/step13.png)
+14. Create, edit, remove some notes, and repeat step 13, the files on Dropbox should also change to reflect the changes locally.

+You should disable auto sync to avoid any unexpected running.
+
+## Set The Output Level To Debug
+
+Go to the plugin settings, scroll down to the section "Debug" -> "alter console log level", and change it from "info" to "debug".
+
+## Check The Output
+
+- If you are on desktop
+
+  Press the keyboard shortcut "ctrl+shift+i" if you are on Windows or Linux, or press "cmd+shift+i" if you are on macOS. You should be able to see the console of Obsidian.

+- If you are using Android

+  You need to [enable USB debugging](https://developer.android.com/studio/debug/dev-options#enable) on your Android, then connect your Android to a computer using USB, then open the **desktop** Chrome browser and go to the special web page <chrome://inspect>. You shall be able to see the "inspect" link inside the special page, then click the link to open the console. After debugging, remember to turn off USB debugging.

+# Export Sync Plans
+
+## What's this?
+
+Everytime the plugin starts a sync, it gathers all required information together, generates a "sync plan" of every operations to every files and folders, and assign the corresponding actual operations.
+
+Thus, if something goes wrong, we should check the sync plan firstly.
+
+## How To Export The Plans?
+
+Please read through the following instructions.
+
+### Disable Auto Sync Firstly
+
+You should disable auto sync to avoid any unexpected running.
+
+### Manual Sync If Not Yet
+
+You should at least sync once, so that at least one sync plan is generated and saved. If you have synced the vualt before, there should be some sync plans already saved.
+
+### Export To The File
+
+Go to the plugin settings, scroll down to the section "Debug" -> "export sync plans", and click the button "Export". \*\*It would generate a new folder `_debug_remotely_save/` in your vault, and generate a file `sync_plans_hist_exported_on_{a_timestamp},md.` inside that folder.
+
+## How To Read The Plans
+
+Open the genrated `sync_plans_hist_exported_on_{a_timestamp},md.`. You should see a json, or multiple jsons. Every json represents a sync plan.
+
+A sync plan looks like this:
+
+```json
+{
+  "ts": 1646960867560,
+  "remoteType": "onedrive",
+  "mixedStates": {
+    "abc.md": {
+      "key": "abc.md",
+      "existRemote": true,
+      "mtimeRemote": 1646566632000,
+      "sizeRemote": 56797,
+      "remoteEncryptedKey": "abc.md",
+      "changeMtimeUsingMapping": true,
+      "existLocal": true,
+      "mtimeLocal": 1646566632000,
+      "sizeLocal": 56797,
+      "decision": "skipUploading",
+      "decisionBranch": 1
+    },
+    "New folder/": {
+      "key": "New folder/",
+      "deltimeRemote": 1646925354372,
+      "existLocal": false,
+      "existRemote": false,
+      "decision": "keepRemoteDelHistFolder",
+      "decisionBranch": 9
+    }
+  }
+}
+```
+
+We usually care about the `mixedStates` property. As you may guess, every item in `mixedStates` represent a file or a folder.
+
+We should find out the file/folder we are interested in (or we believe something goes wrong), then checkout the following properties:
+
+```
+decision
+  What decision is made.
+
+decisionBranch
+  It's a mark of the actual logic in the sync code. Useful to debug.
+
+existRemote
+  Does the file/folder exist on the remote service?
+
+mtimeRemote
+  The "last modeified time" on the remote service.
+
+deltimeRemote
+  The "deletion time" on the remote record.
+
+existLocal
+  Does the file/folder exist locally?
+
+mtimeLocal
+  The max of "last modeified time" and "creation time" locally.
+
+deltimeLocal
+  The "deletion time" locally.
+```
+
+The `decision` SHOULD be determined by the modified times and deletion times, by the logic described in [the doc of sync alogorithm](../sync_algorithm_v2.md). In short, we collect four timestamps (`mtimeRemote`, `deltimeRemote`, `mtimeLocal`, `deltimeLocal`), and respect the max timestamp and its corresponding operation.
+
+## Common Issues
+
+Some users report that their "last modeified time"s or "creation time"s are not set correctly by the operating system. In this case, the plugin cannot do anything because it determines the sync plan by comparing the timestamps. It's suggested to check the settings of the operating system or check whether other programs are doing something to the files.

+# Use `Logstravaganza`

+1. Install it.
+2. Enable it.
+3. Do something, to trigger some console logs.
+4. Checkout `LOGGING-NOTE (device name).md` in the root of your vault.

+
+## Steps
+
+1. Create a Backblaze account [on this page](https://www.backblaze.com/cloud-storage). Credit card info _is not_ required. Backblaze B2 offers 10 GB of free storage.
+
+2. Please be aware that, though B2 provides some free quota, **it may still cost you money if the usage of storage or api requests exceed a certain value!!!** Especially pay attention to the api requests!!!
+
+3. Create a **bucket**, you can leave the default settings, or you can enable the encryption (which is different from what you can set in Remotely Save):
+
+   ![](./s3_backblaze_b2-1-bucket.png)
+   ![](./s3_backblaze_b2-2-create_bucket.png)
+
+4. Copy `Endpoint`, eg. `s3.us-east-005.backblazeb2.com` — it'll be used later.
+
+5. Copy `bucketname` near the 🪣 icon (the "bucket icon") — it'll be used later.
+
+   ![](./s3_backblaze_b2-3-copy.png)
+
+6. Go to **Application Keys**:

+8. Save `keyID` and `applicationKey` — they will be used later.
+
+9. Go to Remotely Save settings in Obsidian and:
+
+   - Choose `S3 or compatibile` in **Remote Service**:
+   - Copy `Endpoint` from Backblaze (see 3. above) to `Endpoint` in Remotely Save
+   - From `endpoint` take `region` (eg. `us-east-005`) and paste it in `endpoint` in Remotely Save
+   - Copy `keyID` (see 7. above) to `Access Key ID` in Remotely Save
+   - Copy `applicationKey` (see 7. above) to `Secret Access Key` in Remotely Save
+   - Copy `bucketname` (see 4. above) to `Bucket Name` in Remotely Save

+# AWS S3 Bucket: How to configure user's policy
+
+## Attention
+
+Please read the doc carefully and adjust the optional fields accordingly. The doc is not fully tested and contributions are welcome.
+
+## AWS Official Docs
+
+- <https://docs.aws.amazon.com/AmazonS3/latest/userguide/access-policy-language-overview.html>
+- <https://docs.aws.amazon.com/AmazonS3/latest/userguide/using-with-s3-actions.html>
+- <https://docs.aws.amazon.com/AmazonS3/latest/API/API_Operations.html>
+
+## Prerequisites
+
+Using the principle of least privilege is crucial for security when allowing a third party system to access your AWS resources.
+
+**Prerequisites**: Ensure you have an AWS account and administrative access to manage IAM policies.
+
+## Step 1: Create a new IAM Policy
+
+1. Log in to your AWS Management Console.
+1. Navigate to the IAM Policies section.
+1. Create a new policy with the following configuration.
+
+**Note**: `my-bucket` is a placeholder. For example, if your bucket's name is `obsidian-data`, the resource line should read `arn:aws:s3:::obsidian-data`.
+
+```JSON
+{
+    "Version": "2012-10-17",
+    "Statement": [
+        {
+            "Sid": "ObsidianObjects",
+            "Effect": "Allow",
+            "Action": [
+                "s3:HeadObject",
+                "s3:PutObject",
+                "s3:CopyObject",
+                "s3:UploadPart",
+                "s3:UploadPartCopy",
+                "s3:ListMultipartUploads",
+                "s3:AbortMultipartUpload",
+                "s3:CompleteMultipartUpload",
+                "s3:ListObjects",
+                "s3:ListObjectsV2",
+                "s3:ListParts",
+                "s3:GetObject",
+                "s3:GetObjectAttributes",
+                "s3:DeleteObject",
+                "s3:DeleteObjects"
+            ],
+            "Resource": "arn:aws:s3:::my-bucket/*"
+        }
+    ]
+}
+```
+
+> The policy allows the Obsidian plugin to list, add, retrieve, and delete objects in the specified S3 bucket.
+
+## Step 2: Attach the Policy to Obsidian user
+
+1. Create a new user in the IAM console. (Never use your own root user, as it would have full access to your AWS account).
+1. When creating the user, select "Attach policy directly" and select the policy created.
+1. Edit the recent created user and go to "Security Credentials" tab to create your access key.
+1. Create an Access Key. If asked for a "use case", select "other"
+1. Use the credentials in the plugin settings. (NEVER share these credentials)
+
+> PS. The bucket doesn't need to have a policy, only the user.
+
+## Verifying the Policy
+
+After attaching the policy, test it by trying to access the S3 bucket through the Obsidian plugin. Ensure that all intended actions can be performed without errors.
+
+## Troubleshooting
+
+If you encounter permission errors, check the policy for typos in the bucket name or actions. Ensure the policy is attached to the correct user.

+
+## Attention
+
+The tutorial author (the author of Remotely Save) is NOT an expert of NAS / Synology. Please read the doc carefully and change it to accommodate your needs by yourself.
+
+**It's dangerous to expose your NAS into public Internet if you don't know how to set up firewalls and other protections.**
+
+## Steps
+
+Synology DSM 7 is used in this tutorial.
+
+1. Create a new shared folder if you don't have one. For this tutorial, a new shared folder `share2` is created. You should assing a proper user to read / write the shared folder.
+   ![](./synology_create_shared_folder.png)
+
+2. Assuming you want to sync your vault into sub folder `哈哈哈/sub folder`, please create the sub folder(s) correspondingly inide the shared folder `share2`.
+
+3. Install webdav server from package center.
+   ![](./synology_install_webdav_server.png)
+
+4. Enter the webdav server settings.
+
+5. If you know how to configure https certificates correctly, you are strongly recommend to enable https.
+
+   For the demonstration purpose, this tutorial enable http server for the later steps.
+
+   Also "Enable DavDepthInfinity", which could speed up the plugin runnings greatly.
+
+   "Apply".
+
+   ![](./synology_webdav_server_settings.png)
+
+6. In Remotely Save settings, you should input your address as:
+
+   `http(s)://<your synology ip or domain>:<port>/<shared folder>/<sub folders>`
+
+   For example, in the tutorial, the proper url should be:
+
+   `http://<ip>:5000/share2/哈哈哈/sub folder`
+
+   Username and password should be the user you configured before with read / write permissions to `share2`.
+
+   Depth header should be "supports depth="infinity"".

+## 注意
+
+教程作者（Remotely Save 作者）**不是** NAS、群晖专家。请仔细阅读文档，并自行改动以适应您自身需求。
+
+**没有设置防火墙和其他保护措施的话，将 NAS 暴露到公网上非常危险。**
+
+## 步骤
+
+本教程有用到群晖 DSM 7。
+
+1. 创建共享文件夹。本教程示例创建了 `share2`。你需要允许某个账号对此的读写权限。
+
+   ![](./synology_create_shared_folder.png)
+
+2. 假设之后你想同步你的库到子文件夹，`哈哈哈/sub folder`，请先在共享文件夹 `share2` 底下创建好。
+
+3. 从套件中心安装 webdav server 。
+   ![](./synology_install_webdav_server.png)
+
+4. 进入 webdav server 设置。
+
+5. 如果你知道如何正确配置 https 证书的话，强烈建议开启 https。
+
+   本教程简化示例，开启了 http。
+
+   也设置“Enable DavDepthInfinity”，这可以加速插件连接速度。
+
+   “Apply”。
+
+   ![](./synology_webdav_server_settings.png)
+
+6. 在 Remotely Save 设置页，你的地址应如下格式输入：
+
+   `http(s)://<your synology ip or domain>:<port>/<shared folder>/<sub folders>`
+
+   比如说，本教程里，正确的地址类似于：
+
+   `http://<ip>:5000/share2/哈哈哈/sub folder`
+
+   用户名和密码是你之前配置了允许读写 `share2` 的那个账号。
+
+   Depth 设置应为“supports depth="infinity"”。

 Here is an overview of the connectability ("connectable" or "not connectable" or "in the plan" or "never") to some services by this plugin.

+The plugin works under the browser environment in Obsidian, so CORS is an issue. Obsidian starts to provide a rich API `requestUrl` for desktop version >= 0.13.25, mobile >= 1.1.1 to bypass the CORS issue. But if the users are still using an older version of Obsidian, they need to configure CORS on server.

+# Sync Ignoring Large Files
+
+Initially, the plugin does not ignore large files.
+
+From the new version in May 2022, it can ignore all files with some sizes. But we need some rules to make the function compatible with existing conditions.
+
+1. If users are using E2E password mode, then the file sizes are compared on the **encrypted sizes**, rather than the original unencripted file sizes. The reasons are: the encrypted ones are in transferations, and the encrypted sizes can be computed from unencrypted sizes but not the reverse.
+
+2. Assuming the file A, is already synced between local device and remote service before.
+
+   - If the local size and remote size are both below the threshold, then the file can be synced normally.
+   - If the local size and remote size are both above the threshold, then the file will be ignored normally.
+   - If the local size is below the threshold, and the remote size is above the threshold, then the plugin **rejects** the sync, and throws the error to the user.
+   - If the local size is above the threshold, and the remote size is below the threshold, then the plugin **rejects** the sync, and throws the error to the user.
+   - When it somes to deletions, the same rules apply.
+
+   The main point is that, if the file sizes "cross the line", the plugin does not introduce any further trouble and just reject to work for this file.

+# Sync Algorithm V3
+
+Drafted on 20240117.
+
+An absolutely better sync algorithm. Better for tracking deletions and better for subbranching.
+
+## Huge Thanks
+
+Basically a combination of algorithm v2 + [synclone](https://github.com/Jwink3101/syncrclone/blob/master/docs/algorithm.md) + [rsinc](https://github.com/ConorWilliams/rsinc) + (some of rclone [bisync](https://rclone.org/bisync/)). All of the later three are released under MIT License so no worries about the licenses.
+
+## Features
+
+Must have
+
+1. true deletion detection
+2. deletion protection (blocking) with a setting
+3. transaction from the old algorithm
+4. user warning show up, **new algorithm needs all clients to be updated!** (deliberately corrput the metadata file??)
+5. filters
+6. conflict warning
+7. partial sync
+
+Nice to have
+
+1. true time and hash
+2. conflict rename
+
+## Description
+
+We have _five_ input sources:
+
+1. local all files
+2. remote all files
+3. _local previous succeeded sync history_
+4. local deletions
+5. remote deletions.
+
+Init run, consuming remote deletions :
+
+Change history data into _local previous succeeded sync history_.
+
+Later runs, use the first, second, third sources **only**.
+
+Bidirectional table is modified based on synclone and rsinc. Incremental push / pull only tables is further modified based on the bidirectional table. The number inside the table cell is the decision branch in the code.
