Implements mode-aware event echo classification, job-arrival range
compression (Req 4.5), and round-collapse flush wiring at all 3
breakpoint-match/structural-event call sites (Requirements 1.1-1.4,
3.5, 3.6). All 4 of task 3.1's tests pass; also closes bug-1609
("continue is as verbose as step").
repl_break.c grew 827->905 lines (13% over the 800-line cap). Unlike
task 2.2's Round Rollup, this logic is wiring inside pre-existing
driver-facing hooks, not a relocatable subsystem - accepted in place
per design.md's established residual-tolerance precedent.
Review independently investigated a one-off ASAN stack-use-after-return
in an unrelated test (sched_sim_record_output_test) surfaced by this
change's stack-layout perturbation: traced to the same documented
pre-existing thread-lifecycle bug class as bug-1598/bug-1632 (an
unjoined picker thread reading a stack-local sim after test-function
return), confirmed via 11/11 clean reruns - logged as bug-1763, not a
regression from this task.

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.
