ads::symbol::get_symbol_info breaks on large TwinCAT projects #8

Closed alex-boring closed 2 years ago

alex-boring commented 2 years ago

Hey, great library, thanks a lot for that!

I am running into an issue when using ads::symbol::get_symbol_info on a large TwinCAT project. With a small one it works just fine (tested with a couple dozen variables). Not sure where the threshold is when it breaks.

Any help would be appreciated! Thanks, Alex

Thanks for the report. Looks like a symbol's comment is longer than 1024 bytes, which is fair enough. (The comment isn't currently used anyway...)

alex-boring commented 2 years ago

Thanks for the fast answer! How would you recommend working around that? (I can't change the comment length in the PLC code in this use case).

birkenfeld commented 2 years ago

Should be fixed in master, can you try with it?

alex-boring commented 2 years ago

Thanks, still the same issue with any large projects. I am not sure if the comment length is the cause. I tested it on a small project with a couple variables and a long comment behind it with 4500 characters. No problem with the long comment on the small project.

Code used for testing:

PROGRAM MAIN
VAR
    heartbeat : USINT;
    test_int : INT := 42;
    test_float : REAL := 3.14159;
    test_string : STRING(20) := 'This is a string';
    test_double : LREAL := 423.14159;
    test_bool : BOOL := TRUE;
    test_array : ARRAY[0..9] OF INT := [1,-101,10101,123,-6665,5412,2222,1234,5667];    // adsffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff ... this goes on for another 4000 characters

END_VAR
birkenfeld commented 2 years ago

Are you sure the traceback is the same? Maybe there's still a related bug...

I assume the symbol/type info contains confidential info and you can't share it?

alex-boring commented 2 years ago

I am running into problems building the master from source right now using cargo. Will fix this and get back to you. Thanks!

birkenfeld commented 2 years ago

I also checked how comments end up in the symbol info now, and the only way I could produce a non-empty comment field was to place the comment on a member of a STRUCT and then to add an instance of that struct to e.g. VAR in PROGRAM MAIN.

Placed directly on a VAR item it would not show up...

alex-boring commented 2 years ago

Testing with STRUCT on the tag 0.4.1 gets me the error message with any comment, no matter how long. Can't build from Master right now, but if it works for you with STRUCT comments I hope this solves my problem in your next tag.

Used for testing on 0.4.1 which fails, struct has one instance in MAIN:

// 
TYPE DUT :
STRUCT  // 
    test : INT; // 
END_STRUCT
END_TYPE
birkenfeld commented 2 years ago

Just using ads = { git = "..." } in Cargo.toml doesn't work? There is no change relative to 0.4.1 except for this fix, so I don't know why the build would fail...

birkenfeld commented 2 years ago

Anyway, with such short comments I see no failure in 0.4.1 either. I'm a bit confused by what's going on - can you make sure the traceback still mentions 'range end index xxx out of range for slice of length 1024' and `C:\Users\testUser\.cargo\registry\src\github.com-1ecc6299db9ec823\ads-0.4.1\src\symbol.rs:252?

If yes, the other question is if there is an issue activating the project after updating, so that you are maybe still seeing the old instance with the long comment...

alex-boring commented 2 years ago

Thanks, I didn't know the command to pull from git directly. Using ads = { git = "https://github.com/birkenfeld/ads-rs.git" } in the Cargo.toml file and the same large project I am getting a new error message, and it is printing my first lines (just for my test setup). Would you like me to open a new Issue for that error message?

@birkenfeld Do you have any example code for getting a struct with its fields (Struct inside of Struct inside of Struct) using get_symbol_info()? I need to get the structure of a specific struct in the PLC code including symbol names, so that I can pull the values for each symbol using handle.read

Sorry for posting it here, did not want to open a new issue for a question

birkenfeld commented 2 years ago

Have you looked at examples/adstool.rs? Its var list subcommand should do something close to that.
