/xce-build now takes a build PROFILE: asan (default, debug+ASAN -> xce.build, backward-compatible), debug (non-ASAN -O0 -g3 -fno-inline -fno-omit-frame-pointer -> build.dbg, for gdb/cores), release (-O3 -> build.release). Each profile uses its own default build dir so variants don't clobber each other; arg2 may still be a legacy build_dir. asan runs the unit suites; debug/release are build-only (the suites are ASAN-oriented and the meson test harness is overlay-fs fragile, bug-924) and print how to run a suite directly. Why: bug-1282/bug-1286 are heisenbugs ASAN perturbs away (no SIGSEGV) and that gdb-on-release turns into a hang/timeout. The non-ASAN -O0 -g3 build reproduces them AND yields a symbolized backtrace under gdb. It immediately paid off: the debug profile ROOT-CAUSED bug-1286 (the round-4 segfault) — myreq_handler (cluster.c:251) does `c = ep->owner` then `ha_dispatch_gate(&c->ha,…)`; on chaotic restart a walCatchupEntry (op 37) vtask runs with ep->owner==NULL, so &c->ha = 0x3ff0 -> deref crash at ha.c:3194. Fix is a NULL-guard in myreq_handler (+ owner-lifecycle). 7.2 now has one remaining blocker (bug-1286, root-caused); bug-1282 deadlock is fixed.

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.
