Add three Phase-5 cases to test_ha_core_safety.c pinning the spurious-failover root cause (research.md §"Phase 4/5"): - CORE RED test_5_1_spurious_failover_suppressed_while_primary_alive: a control-channel flap (transient RDHUP) while a current-term primary is alive (fresh heartbeat) must NOT launch a PreVote failover. FAILs on baseline (Expected 0 Was 5) — the RDHUP-initiation path (ha_on_primary_ctrl_fd_rdhup -> ha_begin_failover -> ha_start_prevote_async synchronous branch) has no ha_heartbeat_is_fresh guard, unlike the deferred ha_failover_stagger_fn path. GREEN when task 5.2 adds that guard. - LIVENESS test_5_1_genuine_loss_elects_and_advances_term: genuine loss (stale heartbeat) still launches a real failover; a failed round re-arms; rapid rounds advance the term. Guards 5.2 against over-suppression (Req 6.1/6.2/6.3). - SAFETY test_5_1_election_safety_one_primary_per_term: two candidates contest the same term; the real handle_request_vote grants at most one vote per term (A=3/B=0), so at most one committing primary per term. Falsifiable Election Safety check mapped to raft/raft.tla (Req 4.1/4.3). Deterministic (no sleeps; clock reads only), c==NULL unit-test mode, clean ha_fini teardown. test_ha_core_safety suite: 17 Tests / 1 Failure (the intended RED); all 2.x/4.x/seam cases still pass; no new ASAN leaks.

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.
