feat(scheduler-core): implement REPL execution control (task 12.1) 
Adds the interactive simulation REPL's execution-control slice (Req 5
AC 22): a single-threaded input loop (readline-based) supporting
step [N], continue, quit, and help, pausing before the first replay
event and blocking the driver loop while active.

Review round 1 raised two findings, both resolved here:

- GNU readline (GPL) was linked directly into xce_scheduler, a shipped
  production daemon. Switched the whole project to libedit (BSD) for
  line editing -- scheduler and controller (xce_test) both now use
  editline/readline.h, API-compatible (readline()/add_history()).

- Getting a clean regression run after the libedit swap required a
  full clean rebuild, which exposed a genuine pre-existing SIGSEGV
  (bug-1504): SnapshotData.internalState was a capnp Data field, and
  this codebase's capnpc-c backend silently no-ops Data-field
  encoding without zero-initializing the caller's stack struct,
  leaving an uninitialized capn_ptr written onto the wire. Fixed by
  switching internalState to List(UInt8) (with a new internalStateLen
  wire field), matching the working FetchFileReply.content/bytesRead
  precedent -- no hand-written accessor code needed.

A second, unrelated instance of the same bug class was found in the
controller's WAL-catchup path (WalCatchupEntry.payload) and
deliberately left unfixed as bug-1505, out of scheduler-core's
boundary; needs its own project-wide Data-field audit.

Scheduler suite: 34/34 clean. RED-phase reproduction recorded in
tasks.md (repl_should_pause() step-budget check disabled -> 2/4
tests fail as expected -> reverted -> 34/34 green).

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.
