Rongsong Shen 575f928bbc plan(job-array-single-wal-record): reopen spec for residual gap closure
User directed (2026-07-16) that this feature's own open residual gaps
be fixed: bug-1443 (restore_job_array()'s bulk-insert partial-visibility
gap), task 4.2's boot-replay fence gap, and task 5.3b's bounded leak.
Unrelated pre-existing bugs 1437/1438 explicitly excluded from this
reopening per user's scope decision.

Adds Phase 7 (tasks 7.1-7.3) to tasks.md:
- 7.1: add a purely-additive kvmgr_reserve() capacity-reservation
  primitive (mirroring the existing kvmgr_capture_keys() template) so
  restore_job_array()'s bulk-insert pass can pre-grow its backing store
  before mutating, closing the dominant N-scaling failure trigger; plus
  make a genuinely-inserted partial prefix always get notified even in
  the now-much-narrower residual failure case
- 7.2: extend the Live Apply Resource Fence's halt-and-fence protection
  to replay_wal() (boot/restart replay), reusing the same primitives
  task 4.1/4.2 already built for the live path
- 7.3: free dataset->rows in sched_handle_dataset()'s jobArray case

spec.json phase reverted to tasks-generated to reflect the reopening.

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.
