lei.chen f2993d1efc fix(controller): trim config versions by ns mtime; unique test tmpdir 
Two pre-existing failures (2026-05-13, commit 491c255) surfaced by the
controller unit-test suite (1070 Tests 2 Failures), both in the config
version storage path:

1. conf_trim_old_versions sorted cluster.bin.* versions by
   second-granularity st_mtime. Versions saved within the same second
   (rapid replication, or the trim test's 15ms-spaced saves) tie, glibc's
   stable mergesort keeps creation order, and the newest (current-pointer)
   entry lands at the protected keep_n index — so nothing is pruned and
   keep_n+1 files remain. Store st_mtim (struct timespec) and compare
   tv_sec then tv_nsec.

2. cr_setup() built its tmpdir path from (pid, time(NULL)) at second
   granularity; a Unity assertion failure longjmps past cr_teardown(),
   leaking the dir, and the next test (same pid+second) silently inherited
   the leftover conf/current — cascading a second failure
   (test_conf_get_saved_tag_no_config read a real tag instead of 0). Add a
   per-invocation counter to the path so no two tests share a dir.

Verified: nix develop ./src --command bash src/tools/xce-build.sh all →
meson 9/9 Ok 0 Fail, controller 1070 Tests 0 Failures, xceadmin 172
passed, frontend Go all ok.

README.md

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.
