Adds `xceadmin config dump CLUSTER_BIN_PATH`, the reverse of `config
build` -- decodes a serialized ClusterConfig back to human-readable text
so a built config can be inspected without a throwaway pycapnp script.
Motivated directly by how bug-1556 (hosts.yaml's max_slot: -1 auto-detect
sentinel silently becoming mxj=0) was actually found: by hand-decoding a
live cluster.bin. The dump renders the same sentinel as
"max_slot=-1 (auto-detect from CPU count)", not the raw uint32.
Also adds parse_size_or_number() to xcecommon.mapping so a queue/host's
sched_stop threshold on a byte-valued resource (maxmem/mem/tmp/maxswap/
maxtmp) can be written as a human-friendly size string ("500MB", "2GB")
instead of a raw byte count; a plain number still passes through
unchanged for non-byte resources like load averages. hosts.schema.json
and queues.schema.json's sched_stop schema gains a matching SizeOrNumber
type. dump_cluster_config() humanizes the same byte-valued thresholds
back on the way out (_format_bytes_human).
New ClusterBinFileError covers every local cluster.bin read/decode
failure mode without letting a raw OSError/capnp.KjException escape the
CLI. RESOURCE_VALTYPE/RESOURCE_ORDTYPE/RESOURCE_FLAG_* made public in
mapping.py so dump_cluster_config can reuse the same int<->name tables
build_cluster_config already uses, keeping both directions in sync by
construction.
256 xceadmin tests pass (incl. new test_config_dump.py and the
parse_size_or_number/SizeOrNumber cases in test_mapping.py/test_cli.py),
verified via `xce-build.sh xceadmin`'s full pinned out-of-tree install
+ pytest run before this commit.

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.
