 <!--
-Put `Fixes #1234` here if this closes an issue, or `#1234` to link without closing.
-
-IMPORTANT: Anything beyond a trivial fix (typo, doc tweak, small obvious bug fix)
-should be discussed and agreed in an issue BEFORE you open a pull request.
-Pull requests for larger changes that have not been discussed in an issue first
-may be closed. This saves everyone's time if the change needs a different approach

-#### For new or changed backends
+#### Was the change discussed in an issue or in the forum before?

 <!--
-Backend pull requests are often sent without the integration tests having been run.
-We cannot merge a backend change until it passes the integration tests.
-
-To be merged, a backend change REQUIRES:
-  1. A clean run of `go run ./fstest/test_all -backends <remote>` (summarise the
-     result below or paste a screenshot of the test_all output in the web browser).
-  2. A test account so the maintainers can run the integration tests daily against
-     the backend on the integration test server.
-
-If the tests aren't quite passing yet and you need help getting them
-to pass, then submit the PR and we can help getting you over the line.
-
-See https://github.com/rclone/rclone/blob/master/CONTRIBUTING.md#writing-a-new-backend

-This file provides guidance to AI coding agents (e.g. Claude Code, Codex, Cursor, Gemini CLI, and similar tools) when working with code in this repository.
-
-Rclone welcomes AI-assisted contributions, but the expectation is that you, the human submitter, understand every line you propose and have compiled and tested it against real rclone code - not just generated it. See the "AI-assisted contributions" section of [CONTRIBUTING.md](CONTRIBUTING.md) before opening a pull request.
-
-## Project Overview
-
-Rclone is a command-line program to sync files and directories to and from cloud storage providers. It's written in Go and supports 70+ backends (cloud storage systems). Think "rsync for cloud storage".
-
-## General Notes
-
-**We take backwards compatibility very seriously.** PRs should not change the observable behaviour of existing commands, flags or rc API without very good reason. Rclone does not try to preserve a stable Go API but try not to change it gratuitously.
-
-Rclone operates with a lot of different backends, so **compatibility is key**. It is the backend integration tests which guarantee that compatibility. Changes should consider both known and unknown backends and should take care not to break functionality of existing installations.
-
-The core parts of rclone under `fs` and `vfs` need to work with all backends and **backend specific hacks won't be merged**. Fixes likely need to go in the relevant backend or if new behaviour is really needed, a new Feature flag needs to be added.
-
-**Changes should be kept to the minimum.** Work hard to make the most elegant, smallest change you can. Do not refactor or re-order code unless necessary as this makes review more challenging. Re-use existing test scaffolding, existing or library routines (e.g. `lib`) where possible.
-
-Make sure added tests **actually test the code you have written** and test the intention behind the change. If you are fixing a problem, write the tests first to reproduce the problem before starting on the fix.
-
-Tests in `fs/operations`, `fs/sync`, `cmd/bisync`, `cmd/gitannex` and `vfs` (the definitive list is in `fstest/test_all/config.yaml`) are run on the integration test machine against **all** the backends, so they **must be prepared to run on backends with limited functionality**. Ideally tests, or parts of tests, should be skipped using the `Fs.Features()` flags on backends which can't support them.

-## Build and Test Commands
-
-```bash
-# Build rclone (simple)
-go build
-
-# Build with version info (preferred)
-make
-
-# Run all unit tests (no cloud credentials needed)
-make quicktest
-# or equivalently:
-RCLONE_CONFIG="/notfound" go test ./...
-
-# Run tests for a specific package
-cd backend/memory && go test -v
-# or from root:
-go test -v ./backend/memory/
-
-# Run a single test
-go test -v -run TestIntegration/FsCheckWrap ./backend/memory/
-
-# Run tests with race detector

-
-## Architecture
-
-### Entry Point and Plugin Registration
-
-`rclone.go` is the main entry point. It imports `backend/all` and `cmd/all` which use Go's `init()` pattern to register all backends and commands. Each backend calls `fs.Register()` with a `fs.RegInfo` struct during init.
-
-### Core Interfaces (`fs/`)
-
-The `fs` package defines the core abstractions:
- **`fs.Fs`** (`fs/types.go`): The filesystem interface every backend must implement (List, NewObject, Put, Mkdir, Rmdir).
- **`fs.Object`** (`fs/types.go`): Interface for a file/object (Open, Update, Remove, SetModTime).
- **`fs.Features`** (`fs/features.go`): Optional capabilities a backend can declare (Purge, Copy, Move, DirMove, etc.). Backends set function pointers for operations they support; nil means not supported.
- **`fs.RegInfo`** (`fs/registry.go`): Registration metadata for a backend including its name, config options, and NewFs constructor.
-
-### Backend Structure (`backend/`)
-
-Each backend is a single Go package (e.g., `backend/s3/`, `backend/drive/`). Key conventions:
- Main implementation in a single file (e.g., `s3.go`) - **do not** split into `fs.go`/`object.go`.
- API types go in a separate `api/types.go` file.
- Test file (e.g., `s3_test.go`) uses `fstests.Run()` from `fstest/fstests` for standardized integration tests.
- Register in `backend/all/all.go` via blank import.
- HTTP-based backends should use `lib/rest` for HTTP calls and `fs/fshttp` for the HTTP client.
- Use `lib/dircache` for directory-ID-based remotes, `lib/oauthutil` for OAuth, `lib/pacer` for rate limiting.
-
-### Command Structure (`cmd/`)
-
-Each command is a package under `cmd/` registered in `cmd/all/all.go` via blank import. Commands use cobra via `cmd.Main()`.
-
-### Key Subsystems
-
- **`fs/operations/`**: Core file operations (Copy, Move, Delete, etc.)
- **`fs/sync/`**: Directory sync logic
- **`fs/march/`**: Parallel directory tree walker used by sync
- **`fs/filter/`**: Include/exclude filtering
- **`fs/accounting/`**: Transfer statistics and bandwidth limiting
- **`fs/config/`**: Configuration file management
- **`vfs/`**: Virtual filesystem layer (used by mount, serve)
- **`librclone/`**: C-compatible library interface for embedding rclone
- **`fstest/`**: Integration test framework; `fstest/fstests/` has the generic backend test suite
-
-## Commit Message Convention
-
-Prefix with the directory of the change, then a colon: `drive: add team drive support - fixes #885`. For cross-cutting changes use a broader prefix like `fs` or `operations`.
-
-Make the first line of your commit message a summary of the change that a user (not a developer) of rclone would like to read. So write `drive: fix server side copy of big files` instead of `drive: no longer set the MimeType in Move or Copy`. This is important because these lines go into the change log which is read by users.
-
-## Code Commenting Style
-
-Comments describe the code as it is now, for a future reader who has no knowledge of the change that introduced it.
-
-Every exported type, function, field, and constant has a **godoc comment** that starts with its name and is phrased as a present-tense statement of what it is or does (`// Mkdir makes the directory (container, bucket)`)
-
-**Document the contract** callers need - preconditions, what's returned, which sentinel errors are returned and when, and any "shouldn't return an error if it already exists" style caveats - rather than the implementation.
-
-**Keep comments terse**: a single line for most things, with extra paragraphs (separated by blank `//` lines) reserved for genuine subtlety.
-
-Inline comments inside function bodies should **explain why** - a non-obvious API quirk, a workaround, a gotcha, or an ordering constraint - and may cite an external reference (forum thread, vendor docs, RFC) when that's what makes the behaviour non-obvious; skip comments that merely restate what the code plainly does.
-
-Use `FIXME` and `TODO` for known shortcomings.
-
-**Do not write comments that narrate the change itself** or compare against the previous behaviour (no "now we also handle...", "changed to...", "previously this returned...", or references to bug/PR numbers in the code) - that context belongs in the commit message, not in source that will outlive the change.
-
-Code comments should only refer to **current** behaviour - and shouldn't describe behaviour that is trivially deducible from reading the code.
-
-## Linting Configuration
-
-Uses golangci-lint v2 with config in `.golangci.yml`. Enabled linters: errcheck, govet, ineffassign, staticcheck, unused, gocritic, misspell, revive, unconvert. The `goimports` formatter is also enabled.
-
-## Documentation
-
- Backend option docs come from `Help:` fields in the Go source Options structs, not from markdown files.
- Command docs are in the command source code (e.g., `cmd/ls/ls.go`).
- Don't commit autogenerated doc changes from `make backenddocs` or `make commanddocs`.
- Website docs are in `docs/content/` as markdown, built with Hugo (`make serve` to preview).
-
-## Fork Workflow
-
-This fork carries agent tooling that upstream does not. Never include `docs/specs/`, `docs/plans/`, `docs/{ARCHITECTURE,DECISIONS,TODO,PERMISSIONS}.md`, `GEMINI.md`, `.claude/`, `.codex/`, `.gemini/` or this section in a PR to rclone/rclone.
-
- Required skill: `superpowers` - check at session start, install if missing. There is no product UI here, so `impeccable` is not needed.
- Specs go in `docs/specs/NNN-slug.md` (permanent). Plans go in `docs/plans/NNN-slug.md` and are removed with `git rm` before merge. This overrides the superpowers default paths.
- Paused or in-flight work is listed under "Now" in `docs/TODO.md` with the handoff to read first.
- Non-trivial work: brainstorm → spec → plan → TDD → review. For trivial fixes say "trivial, skipping spec" and proceed.
- Log things noticed but deliberately not fixed in `docs/TODO.md`, record decisions in `docs/DECISIONS.md`, and keep `docs/ARCHITECTURE.md` in step with structural changes - in the same commit as the code.
- `docs/PERMISSIONS.md` is the source for the `.claude/`, `.codex/` and `.gemini/` permission files - change them together.
- Never push, force-push or commit directly to `master`. Ask before adding or upgrading a dependency (`go get`, `go mod tidy`).
- Done means run in this session and seen passing: `go build`, `go test` on the touched packages, and `golangci-lint run` on them.

-# Rclone Code of Conduct
-
-Like the technical community as a whole, the Rclone team and community
-is made up of a mixture of professionals and volunteers from all over
-the world, working on every aspect of the mission - including
-mentorship, teaching, and connecting people.
-
-Diversity is one of our huge strengths, but it can also lead to
-communication issues and unhappiness. To that end, we have a few
-ground rules that we ask people to adhere to. This code applies
-equally to founders, mentors and those seeking help and guidance.
-
-This isn't an exhaustive list of things that you can't do. Rather,
-take it in the spirit in which it's intended - a guide to make it
-easier to enrich all of us and the technical communities in which we
-participate.
-
-This code of conduct applies to all spaces managed by the Rclone
-project or Rclone Services Ltd. This includes the issue tracker, the
-forum, the GitHub site, the wiki, any other online services or
-in-person events. In addition, violations of this code outside these
-spaces may affect a person's ability to participate within them.
-
- **Be friendly and patient.**
- **Be welcoming.** We strive to be a community that welcomes and
-  supports people of all backgrounds and identities. This includes,
-  but is not limited to members of any race, ethnicity, culture,
-  national origin, colour, immigration status, social and economic
-  class, educational level, sex, sexual orientation, gender identity
-  and expression, age, size, family status, political belief,
-  religion, and mental and physical ability.
- **Be considerate.** Your work will be used by other people, and you
-  in turn will depend on the work of others. Any decision you take
-  will affect users and colleagues, and you should take those
-  consequences into account when making decisions. Remember that we're
-  a world-wide community, so you might not be communicating in someone
-  else's primary language.
- **Be respectful.** Not all of us will agree all the time, but
-  disagreement is no excuse for poor behavior and poor manners. We
-  might all experience some frustration now and then, but we cannot
-  allow that frustration to turn into a personal attack. It's
-  important to remember that a community where people feel
-  uncomfortable or threatened is not a productive one. Members of the
-  Rclone community should be respectful when dealing with other
-  members as well as with people outside the Rclone community.
- **Be careful in the words that you choose.** We are a community of
-  professionals, and we conduct ourselves professionally. Be kind to
-  others. Do not insult or put down other participants. Harassment and
-  other exclusionary behavior aren't acceptable. This includes, but is
-  not limited to:
-  - Violent threats or language directed against another person.
-  - Discriminatory jokes and language.
-  - Posting sexually explicit or violent material.
-  - Posting (or threatening to post) other people's personally
-    identifying information ("doxing").
-  - Personal insults, especially those using racist or sexist terms.
-  - Unwelcome sexual attention.
-  - Advocating for, or encouraging, any of the above behavior.
-  - Repeated harassment of others. In general, if someone asks you to
-    stop, then stop.
- **When we disagree, try to understand why.** Disagreements, both
-  social and technical, happen all the time and Rclone is no
-  exception. It is important that we resolve disagreements and
-  differing views constructively. Remember that we're different. The
-  strength of Rclone comes from its varied community, people from a
-  wide range of backgrounds. Different people have different
-  perspectives on issues. Being unable to understand why someone holds
-  a viewpoint doesn't mean that they're wrong. Don't forget that it is
-  human to err and blaming each other doesn't get us anywhere.
-  Instead, focus on helping to resolve issues and learning from
-  mistakes.
-
-If you believe someone is violating the code of conduct, we ask that
-you report it by emailing [info@rclone.com](mailto:info@rclone.com).

-## AI-assisted contributions
+## CI for your fork ##

-You are welcome to use AI coding assistants (Claude Code, Codex, Cursor, Gemini
-CLI, and similar) to help write your contribution. Rclone has an
-[AGENTS.md](AGENTS.md) file at the top of the repository describing the project's
-conventions; point your tool at it so the code it produces matches rclone's
-style.
+rclone currently uses [GitHub Actions](https://github.com/rclone/rclone/actions) to build and test the project, which should be automatically available for your fork too from the `Actions` tab in your repository.

-However, the same standard applies to every pull request whether or not a tool
-was involved: **you are responsible for the code you submit.** Before you open a
-pull request please make sure that:
-
- You understand every line of the change and can explain why it is correct. If
-  a reviewer asks a question about it, you should be able to answer without
-  going back to the tool.
- You have actually built and run it. At a minimum `go build` and
-  `make quicktest` must pass, and for a backend change you should run the
-  [backend tests](#backend-testing) against a real remote where you can.
- The change is a genuine fix or feature that you have verified solves the
-  problem, not a plausible-looking guess. Unverified, AI-generated pull requests
-  that do not compile, do not pass the tests, invent APIs that do not exist, or
-  do not actually do what the description claims waste maintainer time and are
-  likely to be closed.
- You have trimmed the comments. AI tools tend to add verbose comments that
-  restate what the code plainly does or narrate the change being made; please
-  cut these down to match the [code commenting style](AGENTS.md#code-commenting-style).
-
-In short: an AI assistant is a tool to help *you* contribute, not a substitute
-for understanding and testing your own work.

-## Using Git and GitHub
-
-### Committing your changes
-
-Follow the guideline for [commit messages](#commit-messages) and then:
-
-```console
-git checkout my-new-feature      # To switch to your branch
-git status                       # To see the new and changed files
-git add FILENAME                 # To select FILENAME for the commit
-git status                       # To verify the changes to be committed
-git commit                       # To do the commit
-git log                          # To verify the commit. Use q to quit the log
-```
-
-You can modify the message or changes in the latest commit using:
-
-```console
-git commit --amend
-```
-
-If you amend to commits that have been pushed to GitHub, then you will have to
-[replace your previously pushed commits](#replacing-your-previously-pushed-commits).
-
-### Replacing your previously pushed commits
-
-Note that you are about to rewrite the GitHub history of your branch. It is good
-practice to involve your collaborators before modifying commits that have been
-pushed to GitHub.
-
-Your previously pushed commits are replaced by:
-
-```console
-git push --force origin my-new-feature 
-```
-
-### Basing your changes on the latest master
-
-To base your changes on the latest version of the
-[rclone master](https://github.com/rclone/rclone/tree/master) (upstream):
-
-```console
-git checkout master
-git fetch upstream
-git merge --ff-only
-git push origin --follow-tags    # optional update of your fork in GitHub
-git checkout my-new-feature
-git rebase master
-```
-
-If you rebase commits that have been pushed to GitHub, then you will have to
-[replace your previously pushed commits](#replacing-your-previously-pushed-commits).
-
-### Squashing your commits
-
-To combine your commits into one commit:
-
-```console
-git log                          # To count the commits to squash, e.g. the last 2
-git reset --soft HEAD~2          # To undo the 2 latest commits
-git status                       # To check everything is as expected
-```
-
-If everything is fine, then make the new combined commit:
-
-```console
-git commit                       # To commit the undone commits as one
-```
-
-otherwise, you may roll back using:
-
-```console
-git reflog                       # To check that HEAD{1} is your previous state
-git reset --soft 'HEAD@{1}'      # To roll back to your previous state
-```
-
-If you squash commits that have been pushed to GitHub, then you will have to
-[replace your previously pushed commits](#replacing-your-previously-pushed-commits).
-
-Tip: You may like to use `git rebase -i master` if you are experienced or have a
-more complex situation.
-
-### GitHub Continuous Integration
-
-rclone currently uses [GitHub Actions](https://github.com/rclone/rclone/actions)
-to build and test the project, which should be automatically available for your
-fork too from the `Actions` tab in your repository.
-
-## Testing
-
-### Code quality tests
-
-If you install [golangci-lint](https://github.com/golangci/golangci-lint) then
-you can run the same tests as get run in the CI which can be very helpful.
-
-You can run them with `make check` or with `golangci-lint run ./...`.
-
-Using these tests ensures that the rclone codebase all uses the same coding
-standards. These tests also check for easy mistakes to make (like forgetting
-to check an error return).

-## Writing Documentation
+## Writing Documentation ##

 If you are adding a new feature then please update the documentation.

-The documentation sources are generally in Markdown format, in conformance
-with the CommonMark specification and compatible with GitHub Flavored
-Markdown (GFM). The markdown format and style is checked as part of the lint
-operation that runs automatically on pull requests, to enforce standards and
-consistency. This is based on the [markdownlint](https://github.com/DavidAnson/markdownlint)
-tool by David Anson, which can also be integrated into editors so you can
-perform the same checks while writing. It generally follows Ciro Santilli's
-[Markdown Style Guide](https://cirosantilli.com/markdown-style-guide), which
-is good source if you want to know more.
-
-HTML pages, served as website <rclone.org>, are generated from the Markdown,
-using [Hugo](https://gohugo.io). Note that when generating the HTML pages,
-there is currently used a different algorithm for generating header anchors
-than what GitHub uses for its Markdown rendering. For example, in the HTML docs
-generated by Hugo any leading `-` characters are ignored, which means when
-linking to a header with text `--config string` we therefore need to use the
-link `#config-string` in our Markdown source, which will not work in GitHub's
-preview where `#--config-string` would be the correct link.
-
-Most of the documentation are written directly in text files with extension
-`.md`, mainly within folder `docs/content`. Note that several of such files
-are autogenerated (e.g. the command documentation, and `docs/content/flags.md`),
-or contain autogenerated portions (e.g. the backend documentation under
-`docs/content/commands`). These are marked with an `autogenerated` comment.
-The sources of the autogenerated text are usually Markdown formatted text
-embedded as string values in the Go source code, so you need to locate these
-and edit the `.go` file instead. The `MANUAL.*`, `rclone.1` and other text
-files in the root of the repository are also autogenerated. The autogeneration
-of files, and the website, will be done during the release process. See the
-`make doc` and `make website` targets in the Makefile if you are interested in
-how. You don't need to run these when adding a feature.
-
 If you add a new general flag (not for a backend), then document it in
 `docs/content/docs.md` - the flags there are supposed to be in
 alphabetical order.

 If you add a new backend option/flag, then it should be documented in
-the source file in the `Help:` field:
+the source file in the `Help:` field.  The first line of this is used
+for the flag help, the remainder is shown to the user in `rclone
+config` and is added to the docs with `make backenddocs`.

- Start with the most important information about the option,
-  as a single sentence on a single line.
-  - This text will be used for the command-line flag help.
-  - It will be combined with other information, such as any default value,
-    and the result will look odd if not written as a single sentence.
-  - It should end with a period/full stop character, which will be shown
-    in docs but automatically removed when producing the flag help.
-  - Try to keep it below 80 characters, to reduce text wrapping in the terminal.
- More details can be added in a new paragraph, after an empty line (`"\n\n"`).
-  - Like with docs generated from Markdown, a single line break is ignored
-    and two line breaks creates a new paragraph.
-  - This text will be shown to the user in `rclone config`
-    and in the docs (where it will be added by `make backenddocs`,
-    normally run some time before next release).
- To create options of enumeration type use the `Examples:` field.
-  - Each example value have their own `Help:` field, but they are treated
-    a bit different than the main option help text. They will be shown
-    as an unordered list, therefore a single line break is enough to
-    create a new list item. Also, for enumeration texts like name of
-    countries, it looks better without an ending period/full stop character.
- You can run `make backenddocs` to verify the resulting Markdown.
-  - This will update the autogenerated sections of the backend docs Markdown
-    files under `docs/content`.
-  - It requires you to have [Python](https://www.python.org) installed.
-  - The `backenddocs` make target runs the Python script `bin/make_backend_docs.py`,
-    and you can also run this directly, optionally with the name of a backend
-    as argument to only update the docs for a specific backend.
-  - **Do not** commit the updated Markdown files. This operation is run as part of
-    the release process. Since any manual changes in the autogenerated sections
-    of the Markdown files will then be lost, we have a pull request check that
-    reports error for any changes within the autogenerated sections. Should you
-    have done manual changes outside of the autogenerated sections they must be
-    committed, of course.
- You can run `make serve` to verify the resulting website.
-  - This will build the website and serve it locally, so you can open it in
-    your web browser and verify that the end result looks OK. Check specifically
-    any added links, also in light of the note above regarding different algorithms
-    for generated header anchors.
-  - It requires you to have the [Hugo](https://gohugo.io) tool available.
-  - The `serve` make target depends on the `website` target, which runs the
-    `hugo` command from the `docs` directory to build the website, and then
-    it serves the website locally with an embedded web server using a command
-    `hugo server --logLevel info -w --disableFastRender --ignoreCache`, so you
-    can run similar Hugo commands directly as well.
+The only documentation you need to edit are the `docs/content/*.md`
+files.  The MANUAL.*, rclone.1, web site etc are all auto generated
+from those during the release process.  See the `make doc` and `make
+website` targets in the Makefile if you are interested in how.  You
+don't need to run these when adding a feature.

-When writing documentation for an entirely new backend,
-see [backend documentation](#backend-documentation).
+Documentation for rclone sub commands is with their code, eg
+`cmd/ls/ls.go`.

-If you are updating documentation for a command, you must do that in the
-command source code, e.g. `cmd/ls/ls.go`. Write flag help strings as a single
-sentence on a single line, without a period/full stop character at the end,
-as it will be combined unmodified with other information (such as any default
-value).
+Note that you can use [GitHub's online editor](https://help.github.com/en/github/managing-files-in-a-repository/editing-files-in-another-users-repository)
+for small changes in the docs which makes it very easy.

-### Guidelines for a speedy merge
+Unit tests

- **Do** use [lib/rest](https://pkg.go.dev/github.com/rclone/rclone/lib/rest)
-  if you are implementing a REST like backend and parsing XML/JSON in the backend.
- **Do** use rclone's Client or Transport from [fs/fshttp](https://pkg.go.dev/github.com/rclone/rclone/fs/fshttp)
-  if your backend is HTTP based - this adds features like `--dump bodies`,
-  `--tpslimit`, `--user-agent` without you having to code anything!
- **Do** follow your example backend exactly - use the same code order, function
-  names, layout, structure. **Don't** move stuff around and **Don't** delete the
-  comments.
- **Do not** split your backend up into `fs.go` and `object.go` (there are a few
-  backends like that - don't follow them!)
- **Do** put your API type definitions in a separate file - by preference `api/types.go`
- **Remember** we have >50 backends to maintain so keeping them as similar as
-  possible to each other is a high priority!
+  * Create a config entry called `TestRemote` for the unit tests to use
+  * Create a `backend/remote/remote_test.go` - copy and adjust your example remote
+  * Make sure all tests pass with `go test -v`

-### Managing memory
+Integration tests

-Use rclone's memory pool for upload buffers rather than allocating them
-yourself. This will enable `--max-buffer-memory` and `--use-mmap` and will make
-rclone's memory usage smaller.
-
- If the provider supports multipart or parallel chunk uploads, implement
-  [fs.OpenChunkWriter](https://pkg.go.dev/github.com/rclone/rclone/fs#OpenChunkWriter)
-  and drive it with
-  [multipart.UploadMultipart](https://pkg.go.dev/github.com/rclone/rclone/lib/multipart#UploadMultipart).
-  This gives you pooled chunk buffers, concurrency, retries and
-  `--multi-thread-streams` support for free. See s3/b2 backends for examples.
- If you must buffer data yourself take the buffer from the global pool with
-  [multipart.NewRW](https://pkg.go.dev/github.com/rclone/rclone/lib/multipart#NewRW)
-  and fill it with `io.CopyN`. The `pool.RW` is seekable so the same buffer can
-  be rewound for a retry.
- When using a pooled buffer `Close()` it on all paths so its pages go back to
-  the pool, `Seek(0, io.SeekStart)` inside the retry closure before each
-  attempt, set the request's `ContentLength` explicitly, and if the buffer
-  reaches `http.NewRequest` or an SDK without going through `lib/rest`, wrap it
-  in [readers.NoCloser](https://pkg.go.dev/github.com/rclone/rclone/lib/readers#NoCloser)
-  so the transport can't close it and free its pages before the retry.
-
-### Unit tests
-
- Create a config entry called `TestRemote` for the unit tests to use
- Create a `backend/remote/remote_test.go` - copy and adjust your example remote
- If your backend does chunked uploads, set `ChunkedUpload` in the
-  `fstests.Opt` and implement `SetUploadChunkSize` (and `SetUploadCutoff`)
-  on your `Fs` in the test file so the `FsPutChunked`, `FsPutShortEOF` and
-  `FsPutRetry` tests can run the chunked path with small chunks.
- Make sure all tests pass with `go test -v`
-
-### Integration tests
-
- Add your backend to `fstest/test_all/config.yaml`
-  - Once you've done that then you can use the integration test framework from
-    the project root:
-  - `go run ./fstest/test_all -backends remote`
+  * Add your backend to `fstest/test_all/config.yaml`
+      * Once you've done that then you can use the integration test framework from the project root:
+      * go install ./...
+      * test_all -backends remote

 Or if you want to run the integration tests manually:

- Make sure integration tests pass with
-  - `cd fs/operations`
-  - `go test -v -remote TestRemote:`
-  - `cd fs/sync`
-  - `go test -v -remote TestRemote:`
- If your remote defines `ListR` check with this also
-  - `go test -v -remote TestRemote: -fast-list`
-
-Before a new or changed backend can be merged we require:
-
- A clean run of `go run ./fstest/test_all -backends remote` (please include the
-  result in your pull request).
- A test account for the backend so the maintainers can add it to the
-  [integration test server](https://integration.rclone.org) and keep the backend
-  working as rclone evolves. A backend that we cannot test is likely to break and
-  may be removed.
+  * Make sure integration tests pass with
+      * `cd fs/operations`
+      * `go test -v -remote TestRemote:`
+      * `cd fs/sync`

-### Backend documentation
+Add your fs to the docs - you'll need to pick an icon for it from

+alphabetical order of full name of remote (eg `drive` is ordered as
+`Google Drive`) but with the local file system last.

-Add your backend to the docs.  Keep lists of remotes in alphabetical
-order of full name of remote (e.g. `drive` is ordered as `Google
-Drive`) but with the local file system last.
-
-First add a data file about your backend in
-`docs/data/backends/remote.yaml` - this is used to build the overview
-tables and the tiering info.
-
- Create it with: `bin/manage_backends.py create docs/data/backends/remote.yaml`
- Edit it to fill in the blanks. Look at the [tiers docs](https://rclone.org/tiers/).
- Run this command to fill in the features: `bin/manage_backends.py features docs/data/backends/remote.yaml`
-
-Next edit these files:
-
- `README.md` - main GitHub page
- `docs/content/remote.md` - main docs page (note the backend options are
-  automatically added to this file with `make backenddocs`)
-  - make sure this has the `autogenerated options` comments in (see your
-    reference backend docs)
-  - update them in your backend with `bin/make_backend_docs.py remote`
- `docs/content/docs.md` - list of remotes in config section
- `docs/content/_index.md` - front page of rclone.org
- `docs/layouts/chrome/navbar.html` - add it to the website navigation
- `bin/make_manual.py` - add the page to the `docs` constant
+  * `README.md` - main GitHub page
+  * `docs/content/remote.md` - main docs page (note the backend options are automatically added to this file with `make backenddocs`)
+    * make sure this has the `autogenerated options` comments in (see your reference backend docs)
+    * update them with `make backenddocs` - revert any changes in other backends
+  * `docs/content/overview.md` - overview docs
+  * `docs/content/docs.md` - list of remotes in config section
+  * `docs/content/about.md` - front page of rclone.org
+  * `docs/layouts/chrome/navbar.html` - add it to the website navigation
+  * `bin/make_manual.py` - add the page to the `docs` constant

 Once you've written the docs, run `make serve` and check they look OK
 in the web browser and the links (internal and external) all work.

+Usage

-New features (backends, commands) can also be added "out-of-tree", through Go
-plugins. Changes will be kept in a dynamically loaded file instead of being
-compiled into the main binary. This is useful if you can't merge your changes
-upstream or don't want to maintain a fork of rclone.
-
-### Usage
-
- Naming
-  - Plugins names must have the pattern `librcloneplugin_KIND_NAME.so`.
-  - `KIND` should be one of `backend`, `command` or `bundle`.
-  - Example: A plugin with backend support for PiFS would be called
-    `librcloneplugin_backend_pifs.so`.
- Loading
-  - Supported on macOS & Linux as of now. ([Go issue for Windows support](https://github.com/golang/go/issues/19282))
-  - Supported on rclone v1.50 or greater.
-  - All plugins in the folder specified by variable `$RCLONE_PLUGIN_PATH` are loaded.
-  - If this variable doesn't exist, plugin support is disabled.
-  - Plugins must be compiled against the exact version of rclone to work.
-    (The rclone used during building the plugin must be the same as the source
-    of rclone)

-## Keeping a backend or command out of tree
-
-Rclone was designed to be modular so it is very easy to keep a backend
-or a command out of the main rclone source tree.
-
-So for example if you had a backend which accessed your proprietary
-systems or a command which was specialised for your needs you could
-add them out of tree.
-
-This may be easier than using a plugin and is supported on all
-platforms not just macOS and Linux.
-
-This is explained further in <https://github.com/rclone/rclone_out_of_tree_example>
-which has an example of an out of tree backend `ram` (which is a
-renamed version of the `memory` backend).

-## Triaging Tickets
-
-When a ticket comes in it should be triaged.  This means it should be classified
-by adding labels and placed into a milestone. Quite a lot of tickets need a bit
-of back and forth to determine whether it is a valid ticket so tickets may
-remain without labels or milestone for a while.
+When a ticket comes in it should be triaged.  This means it should be classified by adding labels and placed into a milestone. Quite a lot of tickets need a bit of back and forth to determine whether it is a valid ticket so tickets may remain without labels or milestone for a while.

 Rclone uses the labels like this:

- `bug` - a definitely verified bug
- `can't reproduce` - a problem which we can't reproduce
- `doc fix` - a bug in the documentation - if users need help understanding the
-  docs add this label
- `duplicate` - normally close these and ask the user to subscribe to the original
- `enhancement: new remote` - a new rclone backend
- `enhancement` - a new feature
- `FUSE` - to do with `rclone mount` command
- `good first issue` - mark these if you find a small self-contained issue -
-  these get shown to new visitors to the project
- `help` wanted - mark these if you find a self-contained issue - these get
-  shown to new visitors to the project
- `IMPORTANT` - note to maintainers not to forget to fix this for the release
- `maintenance` - internal enhancement, code re-organisation, etc.
- `Needs Go 1.XX` - waiting for that version of Go to be released
- `question` - not a `bug` or `enhancement` - direct to the forum for next time
- `Remote: XXX` - which rclone backend this affects
- `thinking` - not decided on the course of action yet

-When a ticket is tagged it should be added to a milestone, either the next

 The milestones have these meanings:

- v1.XX - stuff we would like to fit into this release
- v1.XX+1 - stuff we are leaving until the next release
- Soon - stuff we think is a good idea - waiting to be scheduled for a release
- Help wanted - blue sky stuff that might get moved up, or someone could help with
- Known bugs - bugs waiting on external factors or we aren't going to fix for
-  the moment

 ## Making a release

- Enable the [release freeze rule](https://github.com/rclone/rclone/settings/rules/24751862)
- git checkout master # see below for stable branch
- git pull # IMPORTANT
- make fetch-gui-and-commit # bump the embedded GUI if rclone-web has a newer release
- git status - make sure everything is checked in
- Check GitHub actions build for master is Green
- Check the integration tests at <https://integration.rclone.org>
- cat VERSION # check this is the version being released
- make tag # signed tag on HEAD + new changelog entry + docs
- edit docs/content/changelog.md # entries already in point releases are
-  removed automatically
- make tidy
- make doc # again to pick up the changelog edits
- git status - to check for new command docs in docs/content/commands - git add them
- git commit -a -v -m "Version v1.XX.0"
- make check # if this fails, fix, git commit --amend and run it again
- make retag # moves the tag onto the Version commit
- git push origin # without --follow-tags so it doesn't push the tag yet
- Wait for the GitHub actions build of master to complete and check it is
-  green - this is the first time CI sees any commits which were only local,
-  such as security fixes, so it must pass before the tag is pushed
-  - if it fails: fix, git commit, make retag, git push origin and wait again
- git push --follow-tags origin
- \# Wait for the GitHub builds of the tag to complete then...
- \# Don't commit or push anything until after make upload_github as these steps
-  use the tag on HEAD to find the version
- make fetch_binaries
- make tarball
- make vendorball
- make sign_upload
- make check_sign
- make upload
- make upload_test_website # check sponsors are correct/unchanged
- make upload_website
- make upload_github # this triggers the docker plugin and winget workflows
- Check the docker image, docker plugin and winget GitHub actions succeeded
- make startdev # works out the next version for master or a stable branch
- git push
- Disable the release freeze rule
- Release any security advisories
-  - request a CVE for each advisory if not done already
-  - set the patched version on each advisory and publish it
-  - when the CVEs are assigned replace `CVE-PENDING` in the changelog on
-    master and the stable branch then `make upload_website`
- \# announce with forum post, twitter post, and post to announcements list
+  * git checkout master

-## Update dependencies
+Early in the next release cycle update the vendored dependencies

-Early in the next release cycle update the dependencies.
+  * Review any pinned packages in go.mod and remove if possible
+  * make update
+  * git status
+  * git add new files
+  * git commit -a -v

- Active Pins
-  - `github.com/coreos/go-systemd/v22` v22.6.0 - v22.7.0 fails to compile on netbsd
-  - `github.com/hanwen/go-fuse/v2` v2.11.0 - v2.12.0 fails to compile on 32
-    bit linux, awaiting fix for
-    [go-fuse/issues/628](https://github.com/hanwen/go-fuse/issues/628)
- Review Active Pins in go.mod and remove if possible
- `make updatedirect`
- The update ignores the pins so put them back, eg
-  `go get github.com/coreos/go-systemd/v22@v22.6.0` then `go mod tidy`
- `make GOTAGS=cmount`
- `make compiletest`
- Fix anything which doesn't compile at this point and commit changes here
- `git commit -a -v -m "build: update all dependencies"`
+If `make update` fails with errors like this:

-If the `make updatedirect` upgrades the version of go in the `go.mod`
-
-```text
-go 1.22.0
+```
+# github.com/cpuguy83/go-md2man/md2man
+../../../../pkg/mod/github.com/cpuguy83/go-md2man@v1.0.8/md2man/md2man.go:11:16: undefined: blackfriday.EXTENSION_NO_INTRA_EMPHASIS
+../../../../pkg/mod/github.com/cpuguy83/go-md2man@v1.0.8/md2man/md2man.go:12:16: undefined: blackfriday.EXTENSION_TABLES
 ```

-then so this instead `make updatedirectnoupgrade`. This will try each
-upgrade individually. Consider making an upstream bug report for any
-`SKIPPING` lines as these only support the latest Go version not the
-previous version too.
+Can be fixed with

-If `make updatedirect` or `make updatedirectnoupgrade` added a
-`toolchain` directive then remove it. We don't want to force a
-toolchain on our users. Linux packagers are often using a version of
-Go that is a few versions out of date.
-
-Optionally upgrade the direct and indirect dependencies. This is very
-likely to fail if `make updatedirectnoupgrade` was used.
-
- `make update`
- `make GOTAGS=cmount`
- `make compiletest`
- roll back any updates which didn't compile
- `git commit -a -v --amend`
- **NB** watch out for this changing the default go version in `go.mod`
-
-Note that `make update` updates all direct and indirect dependencies
-and there can occasionally be forwards compatibility problems with
-doing that so it may be necessary to roll back dependencies to the
-version specified by `make updatedirect` in order to get rclone to
-build.
-
-Once it compiles locally, push it on a test branch and commit fixes
-until the tests pass.
-
-### Pseudo versions
-
-Go makes pseudo versions for untagged repos and repos not at a tag.
-The pseudo versions on repos that have been tagged before do not get
-updated automatically so need manually checking. These can be found with
-
-```console
-grep -E '[0-9]{14}-[0-9a-f]{12}' go.mod | grep -v indirect | grep -v 'v0\.0\.0'
-```
-
-These will need to be updated manually using the `go get ...@branch`
-syntax.
-
-### Major versions
-
-The above procedure will not upgrade major versions, so v2 to v3.
-However this tool can show which major versions might need to be
-upgraded:
-
-```console
-go run github.com/icholy/gomajor@latest list -major
-```
-
-Expect API breakage when updating major versions.
-
-## Updating Go
-
-When a new Go stable is released update to it. We support the current
-stable Go and the previous release which is in line with the rest of
-the Go ecosystem.
-
-These files will need editing:
-
- `.github/workflows/build.yml` - change current and previous Go versions
- `docs/content/install.md` - change minimum Go version required
- `fs/versioncheck.go` - update minimum Go version required
- `go.mod` - update minimum Go version required
-
-Check it builds
-
- `make GOTAGS=cmount`
- `make compiletest`
-
-Assuming `go1.XX` is current and `go1.YY` is previous version:
-
-Use `git grep go1.YY` and `git grep go1.YY` to look for opportunities
-to remove build tags we no longer need.
-
-Commit with message like this:
-
-```text
-build: update to go1.YY and make go1.YY the minimum required version
-```
-
-Send to CI and if it passes, merge.
-
-### gofix
-
-Updating the minimum required version of Go is a good opportunity to
-run the `go fix` command to modernize Go usage.
-
-This needs to be run for all architectures.
-
-```console
-GOOS=linux go fix -tags cmount ./...
-GOOS=freebsd go fix -tags cmount ./...
-GOOS=windows go fix -tags cmount ./...
-GOOS=darwin go fix -tags cmount ./...
-```
-
-Examine the diff carefully.
-
-Commit with message
-
-```text
-build: modernize Go code with go fix for go1.YY
-```
-
-## Tidy beta
-
-At some point after the release run
-
-```console
-bin/tidy-beta v1.55
-```
-
-where the version number is that of a couple ago to remove old beta binaries.
+    * GO111MODULE=on go get -u github.com/russross/blackfriday@v1.5.2
+    * GO111MODULE=on go mod tidy
+    * GO111MODULE=on go mod vendor
+ 

 ## Making a point release

 If rclone needs a point release due to some horrendous bug:

-Set vars
-
- BASE_TAG=v1.XX          # e.g. v1.52
- NEW_TAG=${BASE_TAG}.Y   # e.g. v1.52.1
- echo $BASE_TAG $NEW_TAG # v1.52 v1.52.1
-
 First make the release branch.  If this is a second point release then
 this will be done already.

- git co -b ${BASE_TAG}-stable ${BASE_TAG}.0
- make startdev # sets the version to ${BASE_TAG}.1
- git push -u origin ${BASE_TAG}-stable
+  * BASE_TAG=v1.XX          # eg v1.49
+  * NEW_TAG=${BASE_TAG}.Y   # eg v1.49.1
+  * echo $BASE_TAG $NEW_TAG # v1.49 v1.49.1
+  * git branch ${BASE_TAG} ${BASE_TAG}-fixes

 Now

- Enable release freeze rule
- git co master
- git pull --rebase
- make fetch-gui-and-commit # update the GUI on master first
- git push
- git co ${BASE_TAG}-stable
- git pull
- cat VERSION # check this is ${NEW_TAG} - if not run make startdev
- `git cherry-pick -x` any fixes, including the GUI update if there was one
-  - for security releases consider updating the Go patch version in
-    `.github/workflows/build.yml` and dependencies with CVE fixes
-  - fixes may depend on commits which weren't picked so push to CI
-    and check it is green before tagging
- Do the steps in "Making a release" above, except
-  - stay on ${BASE_TAG}-stable - don't checkout master or run
-    make fetch-gui-and-commit
-  - check the GitHub actions build for ${BASE_TAG}-stable not master
-  - run the integration tests on ${BASE_TAG}-stable as described below
-  - the release freeze rule is already enabled - leave it until the end
- git co master
- git pull --rebase
- git checkout ${BASE_TAG}-stable docs/content/changelog.md
- git diff --cached # check only the ${NEW_TAG} entry has changed
- git commit -v -m "Changelog updates from Version ${NEW_TAG}" docs/content/changelog.md
- git push
- Disable release freeze rule
-
-Point releases are only made for the latest release. Once v1.(XX+1).0
-is out the ${BASE_TAG}-stable branch is abandoned.
-
-### Running the integration tests on the stable branch
-
-The integration tests at <https://integration.rclone.org> test master.
-To test the stable branch push it to the testing server and run the
-tests there in `screen` as they take a while.
-
-```console
-git push -f rclone@rclone-testing:private-rclone.git ${BASE_TAG}-stable
-ssh rclone@rclone-testing
-screen
-cd ~/integration-test && go run integration-test.go -repo /home/rclone/private-rclone.git -branch v1.XX-stable
-```
-
-## Sponsor logos
-
-If updating the website note that the sponsor logos have been moved out of the
-main repository.
-
-You will need to checkout `/docs/static/img/logos` from <https://github.com/rclone/third-party-logos>
-which is a private repo containing artwork from sponsors.
-
-## Update the website between releases
-
-Create an update website branch based off the last release
-
-```console
-git co -b update-website
-```
-
-If the branch already exists, double check there are no commits that need saving.
-
-Now reset the branch to the last release
-
-```console
-git reset --hard v1.64.0
-```
-
-Create the changes, check them in, test with `make serve` then
-
-```console
-make upload_test_website
-```
-
-Check out <https://test.rclone.org> and when happy
-
-```console
-make upload_website
-```
-
-Cherry pick any changes back to master and the stable branch if it is active.
+  * git co ${BASE_TAG}-fixes
+  * git cherry-pick any fixes
+  * Test (see above)
+  * make NEXT_VERSION=${NEW_TAG} tag
+  * edit docs/content/changelog.md
+  * make TAG=${NEW_TAG} doc
+  * git commit -a -v -m "Version ${NEW_TAG}"
+  * git tag -d ${NEW_TAG}
+  * git tag -s -m "Version ${NEW_TAG}" ${NEW_TAG}
+  * git push --tags -u origin ${BASE_TAG}-fixes
+  * Wait for builds to complete
+  * make BRANCH_PATH= TAG=${NEW_TAG} fetch_binaries
+  * make TAG=${NEW_TAG} tarball
+  * make TAG=${NEW_TAG} sign_upload
+  * make TAG=${NEW_TAG} check_sign
+  * make TAG=${NEW_TAG} upload
+  * make TAG=${NEW_TAG} upload_website
+  * make TAG=${NEW_TAG} upload_github
+  * NB this overwrites the current beta so we need to do this
+  * git co master
+  * make VERSION=${NEW_TAG} startdev
+  * # cherry pick the changes to the changelog and VERSION
+  * git checkout ${BASE_TAG}-fixes VERSION docs/content/changelog.md
+  * git commit --amend
+  * git push
+  * Announce!

 ## Making a manual build of docker

-To do a basic build of rclone's docker image to debug builds locally:
+The rclone docker image should autobuild on docker hub.  If it doesn't
+or needs to be updated then rebuild like this.

-```console
-docker buildx build --load -t rclone/rclone:testing --progress=plain .
-docker run --rm rclone/rclone:testing version
 ```
-
-To test the multipatform build
-
-```console
-docker buildx build -t rclone/rclone:testing --progress=plain --platform linux/amd64,linux/386,linux/arm64,linux/arm/v7,linux/arm/v6 .
-```
-
-To make a full build then set the tags correctly and add `--push`
-
-Note that you can't only build one architecture - you need to build them all.
-
-```console
-docker buildx build --platform linux/amd64,linux/386,linux/arm64,linux/arm/v7,linux/arm/v6 -t rclone/rclone:1.54.1 -t rclone/rclone:1.54 -t rclone/rclone:1 -t rclone/rclone:latest --push .
+docker build -t rclone/rclone:1.49.1 -t rclone/rclone:1.49 -t rclone/rclone:1 -t rclone/rclone:latest .
+docker push rclone/rclone:1.49.1
+docker push rclone/rclone:1.49
+docker push rclone/rclone:1
+docker push rclone/rclone:latest
