Rewires main.c's live scheduling loop onto the new core-driven architecture: xce_sched_driver_translate_pending_events() (task 5.1) -> xce_core_begin_session() -> plugin_begin_session()+sched_account_jobs() -> xce_core_signal_go() -> decision-drain via the registered xce_core_decision_cb_t -> plugin_end_session() -> xce_core_end_session(), all in the new exported xce_sched_driver_run_normal_mode_round() (driver.c), replacing the old inline sched_update()+sched_begin_session() +sched_go()+switch+sched_end_session() sequence. xce_core_go() (task 4.4) is split into xce_core_begin_session()/ xce_core_signal_go() -- a pure decomposition (xce_core_go() itself is now defined in terms of both, task 4.4's approved test suite passes unmodified) -- specifically so the driver can interleave plugin_begin_session()/sched_account_jobs() in the exact safety-critical window task 4.4 deliberately excluded from pure-core scope: after the resval reset, strictly before the picker thread is signaled. This is empirically proven by test_driver_session_ordering.c via real cross-thread happens-before assertions, not just documented. xce_sched_driver_on_decision() is the new registered callback: DISPATCH/PEND forward to the existing sched_publish_dispatch()/ sched_publish_pend_reason(); PREEMPT fails loudly (-ENOSYS, logged) since no xcecli_preempt() client API exists and nothing in the live allocator produces one yet (scheduler-preemption's territory). Adds a --sim CLI flag (parse-only, loud not-yet-implemented failure, since SimDriver is Phase 3).

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.
