Nonterminating processing

Brakeman version: 4.10.1
Rails version: 6
Ruby version: 3

Issue

Hi,

Brakeman appears to be nonterminating and consuming lots of cpu and space on a project. I managed to restrict this to a single model file, which is huge (135klines, it's generated code). I would like to restrict even further to see where, in its chain of treatments, brakeman seems to be stuck. Is there some feature like a more verbose of --debug for such cases? Do you have advice on how to restrict even further the scope of the problem?

Thanks in advance!

135k lines! 😱

I assume this is happening during Processing models...?

There isn't a more verbose debug mode, unfortunately. Usually what I would do is start bisecting the file to see if I can narrow it down to a particular part of the code. But with that many lines, it may just be the size of the file!

You might try --no-branching and see if that helps. If so, it may be possible to fix if you can narrow down the code.

Otherwise, you may have to skip the file with --skip-files.

Yeah, I know :)

Actually interrupting seems to point to always the same point, with this deep clone that seems to be non terminating. Does that ring a bell? It seems to be always about alias_processor.rb.

When I add logs in replace, it seems to go slower and slower. Each new line of log seems to take longer than the previous one to come. It appears to build something bigger and bigger. A few minutes after having started, the ast it prints is large enough to overflow the number of lines my terminal displays :(

[presidentbeef]

Yes, that's right. That's the heart of Brakeman's data flow analysis and is generally the cause of most performance issues.

It may be building a string, or an array, or a set of branches (e.g. lots of assignments in nested ifs) or something of that nature.

Did --no-branching help?

[akimd]

No, --no-branching didn't help. Or maybe it did, but not enough for it to finish.

I also usually bisect in the file until I can pinpoint the issue, but this file is really massive :-( What I'd like to understand is "where" in the processed file Brakeman gets into this tarpit.

On a related note, it might be useful to also support a timeout mechanism for analyses. --skip is useful when you know which files to exclude.

[presidentbeef]

Based on the stack trace, looks like it's processing the value (right-hand side) of a local variable assignment, inside a method.

You could add logging to process_defn and process_lasgn in lib/brakeman/processors/alias_processor.rb to narrow down where to look in your code:

  def process_defn exp
    Brakeman.debug "Processing method `#{exp.method_name}` line #{exp.line}"

  def process_lasgn exp
    Brakeman.debug "Processing assignment to `#{exp.lhs}` line #{exp.line}"

[akimd]

Justin,
That was very helpful! The timestamps show how much brakeman is suffering in there. I'll see if I can spot a pattern in that method that would explain its torments.

Justin,
I don't understand why Brakeman chokes on this single routine. The file size is not an issue, it's only this very routine that drives it nuts. And looking at the code, I don't understand why. In particular, since each time it processes res_hash or opts it gets slower and slower, as if it were maintaining state from one chunk to the next. Although the routine actually running sequentially computations that appear to be not depending on each other. So maybe there is something interesting for you in there, like undesired state persistence over assignments.

The file below suffices to reproduce my problem.

Disclaimer: this code is not written by us, and actually is not "written" at all: it's generated. Also, there are several things in it that don't make sense to me. And I had to mascarade it a bit.

Cheers!

Hi @akimd, thank you for providing this code sample! I can reproduce the slow behavior.

I agree nothing really jumps out at me, so I'll need to take a closer look.

[presidentbeef]

Just as a check in here: I know what's happening. It's hard to see, but after staring at the code for a while I realized there is a thread through the code where opts and res_hash are getting intertwined and passed along even though it looks like there are fresh res_hash and opts values being assigned.

I don't know yet how to fix the issue in Brakeman, but did want to let you know I have not given up yet.

Justin,
You are right, I can see that now too. This piece of code is very hairy and its structure is somewhat unclear...
Thanks for keeping on eye onto it.

If there's no way to get this to work properly, maybe a new type of timeout would be useful.

Cheers!

Fixed with #1820 ⚡

Great news, thanks a lot!
