feat(scheduler-sim-repl-verbosity): task 4.2 - retire redundant per-decision echo
Gates sim_print_decision() so the bare per-decision line no longer
prints under continue mode, making the Round Rollup's summary the
sole source of decision output (Requirement 2.3, closing bug-1610).
step mode and non-interactive/headless runs are completely
unaffected (Requirements 5.1, 5.4). Implemented as a file-local
inline wrapper in sim_loop.c rather than repl.h, since the gated
function is static to that file and repl.h can't see repl_state's
internals without leaking them to every other repl.h consumer.

Fixes 3 pre-existing tests (predating this spec, from scheduler-core)
that pinned the now-intentionally-changed bare-line behavior under
continue mode - each fixed differently based on its actual purpose
rather than uniformly: two kept continue mode with their anchor
switched to the Round Rollup's summary (since they specifically test
continue-mode breakpoint interruption, which step mode would
trivialize), one switched to step mode (since its actual invariant -
print-before-breakpoint-check call order - is mode-independent and
continue mode no longer has any observable anchor for it).

Review caught a second, unguarded sim_print_decision() call site in
sim_reconcile_unaccounted_jobs() (added by an earlier, separately-
merged spec) that design.md's boundary never accounted for - per the
review, this is actually the dominant real-world path for DISPATCH
decisions in replay mode, so leaving it unguarded would have defeated
Requirement 2.3's "sole source of decision output" claim for the
common case. Gated it through the same wrapper; added 2 new tests.

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.
