Subject: [PATCH 02/23] Chore: for cargo publish -p axconfig ======== 1.
 modules/axconfig/src/lib.rs Fallback path: Change from
 ../../configs/dummy.toml to dummy.toml. The original path points to
 Configs/dummy.toml outside the crate directory, which does not exist after
 packaging. Move it directly to the crate directory. 2.
 modules/axconfig/dummy.toml (new) Copy the config file from config/dummy.toml
 to the axconfig crate directory, ensuring the packaged crate includes the
 fallback configuration file. 3. modules/axconfig/Cargo.toml Add README.md.
 Add the following files: [src/**/*, build.rs, dummy.toml, Cargo.toml,
 README.md], ensuring dummy.toml is included in the.crate file. 4.
 modules/axconfig/README.md (new) The README documentation required by
 crates.io. The cargo build-p axconfig command in workspace can also pass
 without affecting the existing development workflow.

+# arceos/modules 發布至 crates.io 順序
+
+依「被依賴者先發布」的拓撲順序，各 crate 僅列出**對同屬 `modules/` 的其它 crate** 的依賴。
+
+## 依賴關係摘要
+
+| Crate | 依賴的 modules |
+|-------|----------------|
+| axconfig | — |
+| axlog | — |
+| axalloc | — |
+| axhal | axconfig |
+| axtask | axhal |
+| axsync | axtask |
+| axipi | axconfig, axhal |
+| axdma | axalloc, axconfig, axhal |
+| axdriver | axalloc?, axconfig?, axdma?, axhal?（均 optional） |
+| axdisplay | axdriver, axsync |
+| axinput | axdriver, axsync |
+| axfs | axalloc, axdriver, axhal, axsync |
+| axmm | axalloc, axconfig, axhal, axsync, axtask；axfs?（optional） |
+| axnet | axconfig, axdriver, axhal, axsync, axtask, axfs |
+| axruntime | axconfig, axhal, axlog；其餘多為 optional |
+
+## 建議發布順序
+
+按下列順序執行 `cargo publish -p <name>`（在 arceos 倉庫根目錄）：
+
+1. **axconfig** — 無 module 依賴  
+2. **axlog** — 無 module 依賴  
+3. **axalloc** — 無 module 依賴  
+4. **axhal** — 依賴 axconfig  
+5. **axtask** — 依賴 axhal  
+6. **axsync** — 依賴 axtask  
+7. **axipi** — 依賴 axconfig, axhal  
+8. **axdma** — 依賴 axalloc, axconfig, axhal  
+9. **axdriver** — 依賴 axalloc, axconfig, axdma, axhal（皆 optional）  
+10. **axdisplay** — 依賴 axdriver, axsync  
+11. **axinput** — 依賴 axdriver, axsync  
+12. **axfs** — 依賴 axalloc, axdriver, axhal, axsync  
+13. **axmm** — 依賴 axalloc, axconfig, axhal, axsync, axtask（axfs optional）  
+14. **axnet** — 依賴 axconfig, axdriver, axhal, axsync, axtask, axfs  
+15. **axruntime** — 依賴其餘 modules（多為 optional）
+
+## 注意
+
+- 上述僅考慮 **modules 內** 的依賴；各 crate 還依賴 workspace 中的 **外部** 依賴（如 `allocator`、`axdriver_*`、`axplat`、`axcpu` 等 git/crates.io）。發布前須確保這些依賴已存在於 crates.io 或改為可發布的 version 依賴。
+- 含 **git 依賴** 的 crate 無法直接發布，需先改為 crates.io 版本或移除該依賴。
+- 每發布一個 crate 後，再對依賴它的 crate 執行 `cargo publish --dry-run` 以確認可通過。

Subject: [PATCH 03/23] Chore: for cargo publish -p axalloc =========== cargo
 publish-p axalloc--dry-run has passed, and cargo build-p axalloc in the
 workspace can be compiled normally.

1. modules/axalloc/Cargo.toml
Dependency: allocator = {workspace = true, features = [bitmap]} changed to
axallocator = {version = 0.1.3-preview.1,default-features = false,features = [bitmap]} (modified to align with crates.io's ax allocator to meet release requirements).
Features: All allocator/... will be renamed to ax allocator/... (e.g., ax allocator/page-alloc-256m, ax allocator/tlsf, etc.).
readme: Added readme = README.md.
2. modules/axalloc/src/lib.rs
use allocator: {...} changed to use axallocator: {...}.
allocator:: SlabByte Allocator / BuddyByte Allocator / TlsfByte Allocator changed to ax allocator::...
The allocator in the file annotation: TlsfByte Allocator has been renamed to axallocator: TlsfByte Allocator.
3. modules/axalloc/src/page.rs
axallocator: The AllocError cannot be automatically converted to AxError. Modify the two alloc_pages (...) to
Map error (|_| AxError: NoMemory)?, and use axerrno: {AxError, AxResult}.
4. modules/axalloc/README.md (new file)
A brief description, feature list, and license for crates.io.
Note: axalloc now depends on the ax allocator 0.1.3-preview.1 from crates.io. If this version has not been released, you must release the allocator (ax allocator) before releasing axalloc.

Subject: [PATCH 04/23] Chore: for cargo publish -p axhal ========== Root
 cause: The API between the axplat version (0.3.0) on crates.io and the git
 dev-v03 branch differs. - crates.io 0.3.0 does not have the percpu module -
 The MemIf in crate.io 0.3.0 does not support the kernel_aspace method - The
 PowerIf method in crates.io 0.3.0 requires the cpu_num method

Modified three files (located in /home/chyyuu/thecodes/publisharceos/arceos/modules/axhal/src/):
- percpu.rs  Enables pub use axplat::percpu::*; conditional gate control via #[cfg (any (feature = defplat, feature = myplat))]. These features are disabled during dry-run, preventing compilation of non-existent modules. During build, defplat is enabled, and the git version of axplat used through patch includes the percpu module.
- mem.rs  Isolate the re-export of kernel_aspace from the main import, similarly controlled by #[cfg (any (feature = defplat, feature = myplat))].
- dummy.rs  Removes kernel_aspace (a feature absent in 0.3.0) from impl MemIf for DummyMem, and adds cpu_num() -> usize (a feature required in 0.3.0) to impl PowerIf for DummyPower. dummy.rs is compiled only on non-embedded targets (e.g., x86_64 host for dry-run) and does not affect make builds.
Verification result:

cargo publish -p axhal --dry-run --allow-dirty  # Successfully completed
make A=examples/helloworld ARCH=riscv64 LOG=info run # Successfully executed and output Hello, world!

Subject: [PATCH 05/23] Chore: for cargo publish -p axtask ==========
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Modified 1 file and added 1 file (both located in /home/chyyuu/thecodes/publisharceos/arceos/modules/axtask/):
1. Modify Cargo.toml
- Add readme = README.md
- Change axconfig = {workspace = true, optional = true} to axconfig = {version = 0.2.1-preview.1, optional = true} (axconfig is already on crates.io)
- Replace  with  (axhal is available on crates.io)
- In the dev-dependencies, axhal is also updated to version dependency {version = 0.2.1-preview.1, features = [fp-simd]}
- In dev-dependencies, axtask's auto-reference is changed to {path = ., features = [test, multitask]}
Other workspace dependencies (e.g., axerrno, cfg-if, log, axpoll) are already versioned in the workspace definition. Setting workspace = true correctly interprets these as versioned dependencies, eliminating the need for modification.

2. Added README.md
A README file was created to describe the functions and features of the axtask module. Verification results:
- cargo publish-p axtask--dry-run--allow-dirty — Successfully completed (downloaded axhal 0.2.1-preview.1 from crates.io and compiled it)
- make A=examples/helloworld ARCH=riscv64 LOG=info run — Successfully executed and output Hello, world! (workspace's [patch.crates-io] automatically redirects axconfig and axhal to the local path)

+[ArceOS](https://github.com/arceos-org/arceos) task management module.
+
+This module provides primitives for task management, including task creation,
+scheduling, sleeping, termination, etc. The scheduler algorithm is configurable
+by cargo features.
+
+## Features
+
+- `multitask`: Enable multi-task support with complex scheduling and more task-related APIs.
+- `irq`: Enable timer-based APIs such as `sleep`, `sleep_until`, and `WaitQueue::wait_timeout`.
+- `preempt`: Enable preemptive scheduling.
+- `sched-fifo`: Use the FIFO cooperative scheduler (enables `multitask`).
+- `sched-rr`: Use the Round-robin preemptive scheduler (enables `multitask` and `preempt`).
+- `sched-cfs`: Use the Completely Fair Scheduler (enables `multitask` and `preempt`).
+- `tls`: Enable kernel space thread-local storage support.
+- `smp`: Enable SMP (symmetric multiprocessing) support.

Subject: [PATCH 06/23] Chore: for cargo publish -p axsync ========== 1. Modify
 /home/chyyuu/thecodes/publisharceos/arceos/modules/axsync/Cargo.toml Add
 README.md. Replace axtask/workspace = true with axtask = {version =
 0.2.1-preview.1} (parsed from crates.io after release). dev-dependencies:
 axsync is updated to {path = ., features = [multitask]} and axtask to
 {version = 0.2.1-preview.1, features = [test]}. 2. Added
 /home/chyyuu/thecodes/publisharceos/arceos/modules/axsync/README.md The
 module description, provided synchronization primitives, and feature
 descriptions have been written. 3. Modify
 /home/chyyuu/thecodes/publisharceos/arceos/Cargo.toml Add to
 [patch.crates-io]: axtask = { path = modules/axtask } axsync = { path =
 modules/axsync } This approach utilizes the local axtask/axsync during
 workspace setup, eliminating the need for crates.io axtask in make run.
 Verification results make A=examples/helloworld ARCH=riscv64 LOG=info run:
 Passed, successfully outputs Hello, world! cargo publish-p axsync--dry-run:
 Passed.

+
+## Primitives
+
+- **Mutex**: A mutual exclusion primitive. With the `multitask` feature, it uses task-aware locking; otherwise it is an alias of `kspin::SpinNoIrq`.
+- **spin**: Re-export of the [kspin](https://crates.io/crates/kspin) crate (spinlocks).
+
+## Features
+
+- `multitask`: Enable multi-threaded support. When enabled, `Mutex` uses blocking that cooperates with the task scheduler; when disabled, `Mutex` is a spinlock.

Subject: [PATCH 20/23] Chore: cargo publish axfeat, arceos_api, axstd,
 arceos_posix_api, axlibc ========== In the [workspace_dependencies] section
 of arceos/Cargo.toml, add version = "0.2.2-preview.1" to arceos_api. Both
 dry-run and production releases passed without additional modifications.

In the [workspace_dependencies] section of arceos/Cargo.toml, add version = "0.2.2-preview.1" to axstd. Both dry-run and release builds passed on the first attempt.

The issue is that build.rs uses the relative path../../ulib/axlibc/include/ to reference external header files, which is not present in the cargo publish sandbox. The solution is:
Skip generating build.rs when external header files are unavailable (use pre-generated files)
Ensure that certgen.rs is included in the release package

The build script does not allow modifying the source directory during publish verification. Modify it to write to OUT_DIR.

arceos/Cargo.toml-for arceos_posix_api with version = "0.2.2-preview.1"
arceos_posix_api/build.rs-Join condition check: If the external header file directory../../ulib/axlibc/include/ does not exist (e.g., in a cargo publish sandbox), skip regenerating ctypes_gen.rs and use the pre-generated version
arceos_posix_api/.gitignore-Clear content to ensure ctypes_gen.rs is included in the release package
arceos_posix_api/src/imp/stdio.rs-Fixed the BufReader::new issue in axio 0.3.0-pre.1 where it was no longer a const function, using spin::Once to delay initialization

arceos/Cargo.toml-Add version = "0.2.2-preview.1" to axlibc
axlibc/build.rs-Write libctypes_gen.rs to OUT_DIR instead of src/, avoiding the publish verification restriction on source directory modifications
axlibc/lib.rs-Use include! (concat! (env! ("OUT_DIR"), "/libctypes_gen.rs")) to import the generated binding file from OUT_DIR
