Gear monthly update April

4 month ,Gear Successfully passed the internal audit . We want to share some important technical updates from last month .

First , We changed it gstd library . We will msg::send* and msg::reply* It becomes a function that can return errors ^[1]. If in the system call layer ,msg::send* and msg::reply* Error code returned , The user can handle the errors in the user layer , for example , Not enough gas . We also Added new system call msg::reply_with_gas and msg::reply_commit_with_gas^[2], To make consumption gas Reply to your message .

Memory page size becomes configurable ^[3]. as everyone knows ,WASM The default memory page size is 64KB. stay OS in , This memory page is smaller ：Linux by 4 KB,macOS by 16 KB. When you enable lazy pages when , Every time you access the contract data, you need to download all the data from the memory WASM page . Now? , We can reduce this by downloading only some pages , This is much smaller than the native page of the host . We can filter according to the page size , for example 4KB or 16 KB, And by using only these parts WASM Data is stored in memory . Now? , The code page size in memory is reduced to 4 KB.

There is another important technology update , exceed gas The limit message will not be skipped now ^[4]. before , When the message exceeds the allowed of the current block gas At the upper limit , We'll push the news to the end of the team . however , Now when we meet a gas The upper limit exceeds... Of the current block gas The cost of the message , We are still trying to process the message .

If the process succeeds or fails due to internal logic , We are right. DB Adopt corresponding changes . If because of gas Failed to execute due to cost limitation , We will restore everything related to this message , Re queue at the head of the queue in the block , And stop processing the current block . This guarantees that there will be more... In the next block gas, Make the message processed successfully .

Let's explain this in simpler terms . before , Each of our blocks has a fixed gas fee . This can also be called “ The budget ”. Every message has gas ceiling . If the message gas The upper limit does not meet the block fee or “ The budget ”, The message will be placed at the end of the line , Processed in an ongoing block . This can lead to some problems , Because that means you can't successfully handle gas Messages with a large upper limit .

Based on recent updates , Even if the news is gas The upper limit is higher than that of the block gas “ The budget ”, We still send messages for processing , Because it's practical gas Consumption may be lower than gas ceiling , So that the message conforms to “ The budget ” The requirements of .
