Rongsong Shen abefc8a128 feat: P2-2 apply_wal_entry — standby WAL replay with LSN advance and type guards
Upgrade apply_wal_entry() from P0 static no-op stub to the real public
standby replay path:

- Reject oversized payloads (> MAX_WAL_PAYLOAD_BYTES) with -EMSGSIZE
- Skip WAL_CHECKPOINT (100) entries silently — local-only markers, never
  replicated to standbys; current_lsn is NOT advanced on skip
- Skip unknown types (> WAL_ENTRY_TYPE_MAX) with WARN log and rc=0 for
  forward compatibility with WAL written by newer controller versions
- Advance current_lsn to hdr->lsn+1 and update last_crc under p->lock
  for all accepted known entries
- Gate restore_job()/worker_from_capnp() calls on p->cluster != NULL so
  unit tests work without a full cluster wired in
- Add NULL guard returning -EINVAL for missing p or hdr

Add public declaration in persist.h with forward-declare stubs for
restore_job/worker_from_capnp in persist.c (avoids heavy cluster.h chain).

Test suite: 5 new Unity tests in test_repl_apply.c covering all branches.
Weak stubs for restore_job/worker_from_capnp in the test file satisfy the
linker without linking job.c/worker.c's heavy dependency graph.
All 5 new tests pass; full controller suite green.

1. commit 规则

  • 每个人 fork 自己的 branch, 从自己的 branch 做 PR,review 完再 commit

2. code format

2.1. C

推荐使用 clang-format,公共配置放在源码里面 xce/.clang-format

(理论上直接使用源码里面 xce/.clang-format 文件格式不会变)

2.1.1. vscode 可以在配置中加上如下内容

"C_Cpp.clang_format_style": "WebKit",
"C_Cpp.clang_format_fallbackStyle": "WebKit",

2.1.2. vim & emacs

clang-format -style="{BasedOnStyle: webkit}" -i XX.c

2.2. golang

使用默认 gofmt

3. build environment and build (example of ubuntu)

3.1 build environment

  • Install nix package management tool
sh <(curl -L https://nixos.org/nix/install) --daemon
  • Edit /etc/nix/nix.conf to make sure
experimental-features = nix-command flakes
sandbox = true
sandbox-fallback = false
substituters = https://mirrors.ustc.edu.cn/nix-channels/store https://cache.nixos.org https://cache.nixos.org/
trusted-users = root <your account>

make sure that you have restarted nix-daemon service after you have changed /etc/nix/nix.conf

  • Install socat and config ssh (for clone by ssh protocol)
nix profile add nixpkgs#socat

.ssh/config

Host gitea.shenrs.eu
	HostName gitea.shenrs.eu
	IdentityFile ~/.ssh/id_ed25519
	ProxyCommand socat - openssl-connect:gitea.shenrs.eu:2022,snihost=gitea.shenrs.eu,verify=0

3.2 checkout source code

3.3 build (for package and release)

cd xce/src

# for build debug version
nix build --option sandbox false .#xcecore_debug

# for normal build
nix build --option sandbox false .#xcecore

You can find the generated binaries at =result= directory

3.4 build (for daily develop)

cd xce/src
nix develop

# using meson to generated build configuration (debug and address sanitize)

meson setup build --buildtype=debug -Db_sanitize=address

# run meson to build
meson compile -C  build

# The generated files will be in build/

3.5 build AppImage package

cd xce/src
nix bundle --bundler github:ralismark/nix-appimage --option sandbox false .#xce

This will create all in one AppImage file which contains everything for package delivery.

4. misc

4.1. Windows remap ctrl and alt key

create a reg file, e.g. remapkey.reg

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout]
"Scancode Map"=hex:00,00,00,00,00,00,00,00,05,00,00,00,38,00,1d,00,1d,00,38,00,38,e0,1d,e0,1d,e0,38,e0,00,00,00,00

then double click remapkey.reg to import it. Restart OS.
