test(xce-test-ha): add worker-rejoin-resync coverage to sequential/chaotic soak modes
Starts a real worker (auto-detects xcecd_virtual vs. real xcecd, mirroring
xce-deploy-ha's own detection) + xce_scheduler alongside the controller
cluster, dispatches a genuine job, kills the primary while it's RUN, and
verifies the worker rejoins the new primary and the job recovers to DONE
via real reconciliation -- closing the "no real daemon-to-daemon smoke
test" gap flagged by worker-rejoin-resync's own feature validation.
Live-verified end-to-end multiple times (sequential and chaotic, 2 rounds
each) against a real 3-node cluster.

Also logs two bugs discovered along the way (not fixed, out of scope for
this test-infra change): bug-1759 (scheduler sim-mode dispatch/PEND
inconsistency) and bug-1760 (scheduler has no periodic post-failover
reconnect check, only a reactive one gated on its own next successful
publish -- a chicken-and-egg deadlock, live-confirmed via 60s+ of stuck
PEND with zero scheduler log activity). bug-1760 is worked around in this
harness only by restarting the scheduler process after each new-primary
election; the underlying gap is unfixed.

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

git clone ssh://forgejo@gitea.shenrs.eu/rshen/xce.git
cd xce

(参考第 1 节,fork 自己的 branch 再提交 PR)

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)

日常开发推荐直接使用 src/tools/xce-build.sh(若在 Claude Code 中开发,对应的是 /xce-build skill), 它会执行 meson setup / meson compile,并在 asan profile 下跑测试。注意它自己不会进入 nix develop 环境,需要先手动 nix develop,或者用 nix develop --command 包一层:

cd xce/src
nix develop

tools/xce-build.sh              # 全部组件 + 全部测试 (asan profile, 输出到 xce.build/)
tools/xce-build.sh controller   # 只构建/测试 controller (lib + controller + xce_test)
tools/xce-build.sh worker       # 只构建 worker
tools/xce-build.sh scheduler    # 只构建/测试 scheduler
tools/xce-build.sh apiserver    # 只构建/测试 apiserver + xcecli (Go)

或者不进入交互式 shell,直接一条命令跑:

cd xce/src
nix develop --command tools/xce-build.sh controller

支持三种 profile(tools/xce-build.sh [component] [profile]):

  • asan(默认):debug + AddressSanitizer,输出目录 xce.build/,会运行测试
  • debug:-O0 -g3 无 sanitizer,输出目录 build.dbg/,仅编译,用于 gdb 调试
  • release:-O3 无 sanitizer,输出目录 build.release/,仅编译,用于 soak/性能测试

注意:单组件构建默认会先 rm -rf 对应的 build 目录再重新配置,若同一目录下已有其他组件的产物会被清掉; 需要在同一目录下累积多个组件时加 --incremental(增量 reconfigure,不清空目录)。

也可以手动执行底层的 nix + meson 命令(xce-build.sh 实际上就是对下面步骤的封装):

cd xce/src
nix develop

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

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

# run meson to build
meson compile -C xce.build

# The generated files will be in xce.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.
