1、内存申请函数调用

write_master->write_master_dim->write_master_bin_ops
->write_master_bin_ops_loop->as_bin_particle_alloc_from_client:
该函数对as_bin_s->particle进行申请内存，并将相关bin属性和值load到
申请的内存中。

2、内存释放函数调用

as_record_done->as_record_destroy->as_record_clean_bins
->as_record_clean_bins_from


点击(此处)折叠或打开

void as_record_clean_bins_from(as_storage_rd *rd, uint16_t from)
{
for (uint16_t i = from; i < rd->n_bins; i++) {
//对每个bin进行释放
as_bin *b = &rd->bins[i];
if (as_bin_inuse(b)) {//bin state有效
as_bin_particle_destroy(b, rd->ns->storage_data_in_memory);
as_bin_set_empty(b);//设置bin的状态AS_BIN_STATE_UNUSED
}
}
}
void as_bin_particle_destroy(as_bin *b, bool free_particle)
{
if (as_bin_is_embedded_particle(b)) {
b->particle = 0;//int、float类型没有申请空间，这里set 0即可
}
else if (b->particle) {
if (free_particle) {
particle_vtable[as_bin_get_particle_type(b)]->destructor_fn(b->particle);
}
//根据类型调用destructor函数，blob的调用blob_destruct，其实是cf_free(p)
//释放了空间，将其set 0
b->particle = 0;
}
}
