"""validate_models_json —— database-table-definition-spec 机械校验器(M11b-2b-A 修复版 rev3)。
|
||
|
||
QC #4/#7/#9/#10 要求:表定义 JSON 必须是 spec 规定的四段式(summary/fields/indexes/
|
||
codes),类型必须是 spec 声明的抽象类型,主键 id 必须是 str/length>=32,索引必须用
|
||
``idxtype`` + ``idxfields``。本脚本把这些规则变成**可执行的断言**,任何一份 models/*.json
|
||
不合规就非零退出(真源不合规同样 FAIL —— QC #9:真源不合规则引用方不可能合规)。
|
||
|
||
本版本修复 QC 退回项(只改本脚本,不改任何 models/*.json):
|
||
QC #2 抽象类型误报:纯抽象类型名(datetime/timestamp/date/time/text/long/…)一律放行,
|
||
只有 type 字符串本身含括号或空格(方言写法 varchar(64)/decimal(15,2)/datetime(3))
|
||
或本身就是 spec 不存在的非抽象类型名(varchar/bigint/json/blob/…)才判违规。
|
||
QC #3 CLI 与文档一致:argparse 真正提供 --allow-registered-deviation(见下方「用法」)。
|
||
QC #4 root_keys_ok:由 validate_model 显式计算 (not missing and not extra) 并随结果返回,
|
||
main() 直接打印该布尔值,不再用「错误串里是否含『四段式』」猜测。
|
||
QC #5 引用式 key/schema:spec 不承认引用式结构,直接判 ERROR 并提示改为内联四段式;
|
||
COMPLIANCE_DEVIATIONS 中针对 pbl_runtime_event/pbl_entity_state 的 4 条失效登记项
|
||
一并删除(引用式在根键检查处即 FAIL,根本到不了 fields 校验,登记形同虚设)。
|
||
QC #1(本轮)放行机制对 auto_increment 生效:字段段「spec 未定义键」检查原先无条件报错,
|
||
导致 (表名,"id","auto-increment") 即使已登记、即使传了 --allow-registered-deviation,
|
||
仍残留 `fields[N](id) 含 spec 未定义键: auto_increment` 而整体 FAIL —— id-not-str32
|
||
可豁免、auto_increment 不可豁免,机制自相矛盾。现在该检查改为**偏离感知**:
|
||
id 上的 auto_increment 键统一交由 id 分支按 strict/allow 两态处理(已登记 + 传开关
|
||
→ 降级为 DEVIATION(registered) 明细,不计入 errors;未登记或未传开关 → 照旧 ERROR);
|
||
其它字段上的未定义键也支持通用登记键 (表名, 列名, "unknown-key:<键名>"),同样两态。
|
||
|
||
偏离放行语义(唯一允许的偏离,需 --allow-registered-deviation 显式声明才放行):
|
||
1) (表名, "id", "id-not-str32") —— 主键 id 非 str 或 length<32;
|
||
2) (表名, "id", "auto-increment") —— id 带 spec 未定义键 auto_increment;
|
||
3) (表名, 列名, "unknown-key:<K>") —— 任意字段带 spec 未定义键 <K>(通用形式)。
|
||
未传该开关时上述项仍判 ERROR,并打印「需 --allow-registered-deviation 放行」提示;传入时
|
||
逐条打印 DEVIATION(registered) 明细(含登记说明),不静默放过。
|
||
注意:只有**登记过**的才可能放行;登记表为空时 --allow-registered-deviation 不放行任何项。
|
||
典型场景:分区表物理主键需要 long + auto_increment(MySQL 1503:分区键必须进主键)。
|
||
若某表确需此类写法,须先在其模块任务里把 (表名,"id","id-not-str32") 与
|
||
(表名,"id","auto-increment") 登记进 COMPLIANCE_DEVIATIONS,再配合开关使用 —— 两者缺一不可,
|
||
只登记不传开关仍 FAIL,只传开关不登记也 FAIL(本文件末尾自测 5 给出四态实测输出)。
|
||
|
||
用法:
|
||
python validate_models_json.py <models目录1> [<目录2> ...]
|
||
python validate_models_json.py --allow-registered-deviation <models目录>
|
||
python validate_models_json.py --files a.json b.json <models目录>
