dispatch_a_job_() mutates job.state/job.allocs directly then persists, firing no hooks at all. apply_committed_entry()'s later apply of that same WAL_JOB_DISPATCH entry sees state already matches the value it just set moments earlier (under the same lock) and reports JOB_TRANSITION_NOOP_DUPLICATE, silently skipping its own would-be notify. Result: the apiserver is never told a job reached RUN -- xcecli jobs list shows it stuck at PEND forever, no restart involved. New persist_notify_job_updated_already_persisted(cluster_t*, job_t*) (persist.c/persist.h), called from dispatch_a_job_()'s success branch right after unlock(j). Mirrors apply_committed_entry()'s own identical Hazard-1-guarded hook fire exactly -- same t_apply_seam_notifying guard, same hook (HOOK_DETAIL_JOB_UPDATE's AFTER_EVENT), same detail -- without which persist_job_hook_fun (also subscribed to this hook) would redundantly re-append the transition as a second, duplicate WAL_JOB_UPDATE entry. The flag stays file-private to persist.c; this is job.c's only sanctioned way to reach it. record_job_start_fact()/record_job_finish_fact() needed no change -- their durable-append-only pattern (defer mutation+notify to apply_committed_entry entirely) is already correct; only dispatch_a_job_()'s broken hybrid (direct mutation, no notify at all) was ever the problem.

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.
