> 内容：`engine/task/`（Task 基类、TaskManager、project/

> 拆分顺序第 8 位。
|
||
|
||
## 1. 目标形态
|
||
|
||
```
|
||
oaktask/
|
||
include/oaktask/{task.h, manager.h, project.h, types.h, export.h}
|
||
src/
|
||
tests/ # oaktask_gtest
|
||
```
|
||
|
||
## 2. 冻结 C API
|
||
|
||
### 2.1 `oaktask/task.h`（单任务句柄，照 oakengine/task.h 模板对齐）
|
||
|
||
```c
|
||
typedef struct OakTaskTask OakTaskTask;
|
||
OAKTK_API void oaktask_task_free(OakTaskTask *t);
|
||
OAKTK_API int oaktask_task_start(OakTaskTask *t); /* 异步 */
|
||
OAKTK_API int oaktask_task_start_sync(OakTaskTask *t);
|
||
OAKTK_API int oaktask_task_cancel(OakTaskTask *t);
|
||
OAKTK_API int oaktask_task_is_finished(const OakTaskTask *t);
|
||
OAKTK_API int oaktask_task_succeeded(const OakTaskTask *t);
|
||
OAKTK_API int oaktask_task_progress(const OakTaskTask *t, double *out);
|
||
OAKTK_API int oaktask_task_title(OakTaskTask *t, char *buf, int n);
|
||
OAKTK_API int oaktask_task_error(OakTaskTask *t, char *buf, int n);
|
||
/* 事件：STARTED/PROGRESS/FINISHED（id 沿用 oakengine events 段） */
|
||
OAKTK_API int64_t oaktask_task_subscribe(OakTaskTask *t, int32_t event_id,
|
||
oaktask_event_fn fn, void *userdata);
|
||
```
|
||
|
||
### 2.2 `oaktask/project.h`（任务工厂 + 结果访问器）
|
||
|
||
```c
|
||
OAKTK_API OakTaskTask *oaktask_create_project_load(const char *filename);
|
||
OAKTK_API OakTaskTask *oaktask_create_project_save(OakNodeProject *p,
|
||
const char *filename_or_NULL, int use_compression,
|
||
const void *layout_or_NULL);
|
||
OAKTK_API OakTaskTask *oaktask_create_project_import(OakNodeNode *folder,
|
||
const char *const *urls, int url_count);
|
||
OAKTK_API OakTaskTask *oaktask_create_project_load_otio(
|
||
const char *filename, const int *sequence_indexes, int count);
|
||
OAKTK_API OakTaskTask *oaktask_create_project_save_otio(
|
||
OakNodeProject *p, const char *filename, const int *sequence_indexes,
|
||
int count);
|
||
/* import 结果（task 成功后读，borrowed） */
|
||
OAKTK_API void *oaktask_import_take_command(OakTaskTask *t); /* 所有权转移 */
|
||
OAKTK_API int oaktask_import_footage_count(OakTaskTask *t);
|
||
OAKTK_API OakNodeNode *oaktask_import_footage_at(OakTaskTask *t, int i);
|
||
OAKTK_API int oaktask_import_invalid_count(OakTaskTask *t);
|
||
OAKTK_API int oaktask_import_invalid_at(OakTaskTask *t, int i,
|
||
char *buf, int n);
|
||
/* load 结果 */
|
||
OAKTK_API OakNodeProject *oaktask_load_take_project(OakTaskTask *t);
|
||
```
|
||
|
||
### 2.3 `oaktask/manager.h`
|
||
|
||
```c
|
||
OAKTK_API int oaktask_manager_count(void);
|
||
OAKTK_API OakTaskTask *oaktask_manager_at(int i); /* borrowed */
|
||
OAKTK_API void oaktask_manager_delete_finished(void);
|
||
/* 事件：TASK_ADDED/REMOVED/FAILED/LIST_CHANGED */
|
||
OAKTK_API int64_t oaktask_manager_subscribe(int32_t event_id,
|
||
oaktask_event_fn fn, void *userdata);
|
||
OAKTK_API void oaktask_unsubscribe(int64_t id);
|
||
```
|
||
|
||
## 3. 切割点
|
||
|
||
| 现状 | 处理 |
|
||
|---|---|
|
||
| task → node/ 38（footage 6、project 5、sequence 3、serializer/layout 3、colormanager 2 等） | 全部经 oaknode C ABI + 适配类（M3 已就位）——本手册工作量主体 |
|
||
| task → codec/ 4 | 经 oakcodec C ABI（M5） |
|
||
| task → render/ 4 | 经 oakrender C ABI（M7） |
|
||
| task → timeline/ 1 | 经 oaktimeline C ABI（M4） |
|
||
| task → coreengine.h 2 | coreengine 的 Task 注册点改为 oaktask_manager 自管（manager 原本就是单例，注册调用内聚进 oaktask） |
|
||
|
||
## 4. 测试（映射 03 §2/§3）
|
||
|
||
- 每个工厂 1 个用例：demo.mp4 import（footage_count>0、command 可
|
||
入栈）、save/load 往返（临时目录 .ove，load 后 project 非空、
|
||
root 非空）。
|
||
- start_sync 成功/失败路径（不存在文件 → failed + error 非空）。
|
||
- 事件：STARTED→PROGRESS→FINISHED 序列（导入任务断言至少一次
|
||
PROGRESS 且 FINISHED.succeeded==1）。
|
||
- manager：添加/删除/list_changed 事件。
|
||
- `oaktask_debug_alive_count()` 泄漏断言。
