Summary: This change introduces the `Symbolizer::GetEnvP()` method that returns a pointer to environment array used for spawning the symbolizer process. The motivation is to allow implementations to customise the environment if required. The default implementation just returns `__sanitizer::GetEnviron()` which (provided it's implemented) should preserve the existing behaviours of the various implementations. This change has been plumbed through the `internal_spawn(...)` and `StartSubprocess(...)` process spawning implementations. For the `StartSubprocess()` implementation we need to call `execve()` rather than `execv()` to pass the environment. However, it appears that `internal_execve(...)` exists in sanitizer_common so this patch use that which seems like a nice clean up. Support in the Windows implementation of `SymbolizerProcess:StartSymbolizerSubprocess()` has not been added because the Windows sanitizer runtime doesn't implement `GetEnviron()`. rdar://problem/58789439 Reviewers: kubamracek, yln, dvyukov, vitalybuka, eugenis, phosek, aizatsky, rnk Subscribers: #sanitizers, llvm-commits Tags: #sanitizers Differential Revision: https://reviews.llvm.org/D76666 |
