20 : and is not vm-specific, but a part of the runtime.
21 : TODO: should we move this out of the CPI section?
22 :
23 : The bulk of the logic is concerned with unifying the privileges for each duplicated account,
24 : ensuring that each duplicate account referenced has the same privileges. It also performs some
25 : priviledge checks, for example ensuring the necessary signatures are present.
26 :
27 : TODO: instruction calling convention: const parameters after non-const.
28 :
29 : Assumptions:
30 : - We do not have more than 256 unique accounts in the callee_instr.
31 : This limit comes from the fact that a Solana transaction cannot
32 : refefence more than 256 unique accounts, due to the transaction
33 : serialization format.
34 : - callee_instr is not null.
35 : - callee_instr->acct_pubkeys is at least as long as callee_instr->acct_cnt
36 : - instr_ctx->txn_ctx->accounts_cnt is less than UCHAR_MAX.
37 : This is likely because the transaction is limited to 256 accounts.
38 : - callee_instr->program_id is set to UCHAR_MAX if account is not in instr_ctx->txn_ctx.
39 : - instruction_accounts is a 256-length empty array.
40 :
41 : Parameters:
42 : - callee_instr
43 : - instr_ctx
44 : - instruction_accounts
45 : - instruction_accounts_cnt
46 : - signers
47 : - signers_cnt
48 :
49 : Returns:
50 : - instruction_accounts
51 : - instruction_accounts_cnt
52 : Populated with the instruction accounts with normalized permissions.
53 :
54 : TODO: is it possible to pass the transaction indexes of the accounts in?
55 : This would allow us to make some of these algorithms more efficient.
