/* test_bg_keep.c — 批①`background_keepalive` 声明层宿主单测。
|
||||
*
|
||||
* 验证 meow_parse_app_json 对 app.json 后台三位（background / background_audio /
|
||||
* background_keepalive）的解析与 meow_acct_sync 透传，重点覆盖**前缀不串扰**：
|
||||
* - "background_keepalive":true → a->background_keepalive=='1'；且 background/background_audio
|
||||
* 在该行不被误命中（分别是 0/0）；
|
||||
* - background:true → a->background=='1'（独立键匹配不受影响）；
|
||||
* - background_audio:true → a->background_audio=='1'；
|
||||
* - 一行三键并存：三者各归其位；
|
||||
* - meow_acct_sync 透传 background_keepalive 到注册表。
|
||||
* 实现手法同 test_fg_act.c：真实 include app_launcher.c，-ffunction-sections -Wl,--gc-sections
|
||||
* 只保留 parseInt/acct_sync/upsert/find 触及函数；json_str/meow_parse_depends/logmsg 由本文件提供
|
||||
* 忠实桩（json_str 复刻 util.c 语义，含键前缀独立 ident_ch + 整体 UTF-8 截断）。
|
||||
*
|
||||
* 运行（patch_v2/meow_launcherd 下）：
|
||||
* gcc -D_GNU_SOURCE -Wall -Wextra -ffunction-sections -Wl,--gc-sections \
|
||||
* -I. -o test_bg_keep test_bg_keep.c && ./test_bg_keep
|
||||
* 全 PASS -> exit 0。
