Rongsong Shen a289edb777 feat: ha_state_t, ha_config_t, ha_init/fini, role enum + config validation (P1-2)
- Full ha.h: ctrl_role_t enum (CTRL_PRIMARY/CTRL_STANDBY), ha_config_t,
  ha_state_t with _Atomic fields (term, role, applied_lsn, promotion
  counters, watchdog_stop), pthread_mutex_t lock, and public API.
- endpoint_t* omitted from ha_state_t — including netio.h would pull
  OpenSSL headers and risk circular deps; watchdog (P1-3) includes
  netio.h directly where needed.
- ha_init validates: heartbeat_interval_ms >= 2000, heartbeat_timeout_ms
  >= heartbeat_interval_ms, election_timeout_ms >= 500; returns -EINVAL
  on bad config; zeros struct and sets initial role to CTRL_STANDBY.
- ha_fini destroys mutex; watchdog thread join deferred to P1-3.
- am_i_primary / ha_promote_to_primary / ha_demote_to_standby are
  no-op stubs; cluster_t->ha field not yet wired (P1-5), so these avoid
  incomplete-type dereferences until then.
- TDD: 5 new tests in test_ha_role.c confirmed RED before implementation,
  all 5 GREEN after; all prior controller tests remain 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.
