Unexpected exit codes

[sakulstra]

Hello was just debugging some rather weird issue on foundry and am now wondering if that's expected or not (to me it was not).

When building a project with a rather huge library and using:
forge build --sizes on ci

The code will build correctly and yield sth like:

forge build --sizes
[⠊] Compiling...
[⠔] Compiling 123 files with 0.8.10
[⠊] Solc 0.8.10 finished in 16.40s
Compiler run successful (with warnings)

... tableWithSizes

also forge test etc will just work.

---

That said, while running:

• forge build; echo "$?" will yield 0 exit code
• forge build --sizes; echo "$?" will yield 1 exit code

I assume the rational here is that in the case of:

Contract	Size (kB)	Margin (kB)
DeployPayloads	102.679	-78.103

I surpassed the limit, so exit code is 1.

That said, building, testing & deploying works just fine as DeployPayloads in this case is a library which is only used in scripts & tests.

edit: Thinking a bit more about this, pretty sure if qualifies as a bug:

• it's unexpected that different build commands yield different exit codes
• if by intention, scripts & tests & libraries only used in the two should be excluded from this rule as they can(and often do) surpass limits without harm
