James Clampffer updated HDFS-11388:
-----------------------------------
Parent Issue: HDFS-14032 (was: HDFS-8707)
> libhdfs++: Add an alternative to assert()
> -----------------------------------------
>
> Key: HDFS-11388
> URL: https://issues.apache.org/jira/browse/HDFS-11388
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: hdfs-client
> Reporter: James Clampffer
> Priority: Minor
>
> There's a few places we use C's assert, in a lot of applications it would be
> better to switch to something that doesn't necessarily call abort() right
> away.
> Example would be a large program that uses temp files or is responsible for
> freeing shared memory used for IPC. Aborting the process will clean up
> resources private to the process but leave other sorts of resources hanging
> around. If assert is replaced by a different macro it could throw or signal
> to indicate that it's no longer safe to use the library but give the rest of
> the application a chance to clean up unrelated resources.
> I'd also be nice to have a variant that wasn't compiled out on release builds
> for inexpensive checks. There have been issues in the past where even -O2
> optimized release builds were able to collapse templates/inline/devirtualize
> things such that code that looked like it had been working started acting
> weird (was relying on UB) and catching that with existing checks would be
> valuable.
