Bugs fixed, discovered across a day of live-operator testing against a real deployed cluster: - bug-1584: clock anchors never initialized to real wall-clock values, timestamps showed system uptime instead of Unix epoch. - bug-1585: heap-use-after-free in the normal-mode driver's periodic resval update path -- core_events.c's RESVALS_FULL/_DELTA handlers do a shallow zarray_put() of the wire-decoded xce_val_t*, but driver.c's release_translated_payload() unconditionally freed the same decoded array right after, so the next periodic report for the same worker+resource triggered a UAF read via kill_sched_resval(). New regression test: test_resval_ownership.c. - bug-1587/1588/1591: raw-ns/raw-uint64 jobid/timestamp prints across the REPL/SIM family converted to the same human-readable formatting already used elsewhere (fmt_jobid(), timestamp formatting). - bug-1590: repl_info.c's XCE_VAL_NUMERIC checks corrected to Value_u_fvalue, fixing `info worker`/`info resource` falling back to 0.00 for real numeric resvals. task 12.5 (Req 5.22 amendment) -- five REPL gaps surfaced by a live operator session, each with its own bug id: - bug-1594: `continue`/`step` reaching EOF with no breakpoint hit now re-enters the REPL via xce_repl_on_replay_complete() instead of exiting the process; step/continue issued after replay is already complete re-prompt instead of silently exiting. - bug-1595: `step`/`continue` now echo each input event (not just decisions) via repl_print_event_summary(), in real event/decision order. - bug-1593: `info resource <name>|all` now reports resource definition metadata restricted to XCE_RESF_GLOBAL/XCE_RESF_SHARED resources, read from core->sharedInst, instead of aggregating host-based resources across every worker. - bug-1596: repl_split_tokens() strips one matching pair of surrounding quote characters from each token. See requirements.md's Req 5 AC 22 "Amendment (2026-08-19)" for the full rationale on each of the five task 12.5 gaps. Full scheduler suite green (41/42; the one remaining failure, test_recordstart_symlink_escape_replies_error, is the pre-existing unrelated bug-1560). |

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.
