Auto-port 4.2: ChannelInitializer: correct misleading comment on exceptionCaught route#16853
Merged
Conversation
…te (#16847) Motivation: The catch block in `ChannelInitializer.initChannel(ChannelHandlerContext)` currently attributes the explicit `exceptionCaught(...)` call to two reasons that don't match the current code: ```java } catch (Throwable cause) { // Explicitly call exceptionCaught(...) as we removed the handler before calling initChannel(...). // We do so to prevent multiple calls to initChannel(...). exceptionCaught(ctx, cause); } finally { if (!ctx.isRemoved()) { ctx.pipeline().remove(this); } } ``` - The handler is **not** removed before `initChannel(...)` is called — removal happens in the `finally` block immediately below. - Re-entrance is guarded by the `initMap.add(ctx)` check at the top of the method, **not** by this catch block. Both clauses of the comment mislead a reader trying to understand why the catch block exists. Modification: Rewrite the two-line comment to name the actual mechanisms: - the `exceptionCaught(...)` call routes the failure into the pipeline; - re-entrance is guarded by `initMap.add(ctx)` above; - handler removal happens in the `finally` block below. No code change. Result: Future readers of `initChannel(ChannelHandlerContext)` can trust the comment instead of having to cross-check it against the surrounding code. Fixes #16846. The same wording exists on 4.1, 4.2, and 5.0; targeting 4.1 so auto-port carries it forward. (cherry picked from commit 22d1be6)

Auto-port of #16847 to 4.2
Cherry-picked commit: 22d1be6
Motivation:
The catch block in
ChannelInitializer.initChannel(ChannelHandlerContext)currently attributes the explicitexceptionCaught(...)call to two reasons that don't match the current code:initChannel(...)is called — removal happens in thefinallyblock immediately below.initMap.add(ctx)check at the top of the method, not by this catch block.Both clauses of the comment mislead a reader trying to understand why the catch block exists.
Modification:
Rewrite the two-line comment to name the actual mechanisms:
exceptionCaught(...)call routes the failure into the pipeline;initMap.add(ctx)above;finallyblock below.No code change.
Result:
Future readers of
initChannel(ChannelHandlerContext)can trust the comment instead of having to cross-check it against the surrounding code.Fixes #16846.
The same wording exists on 4.1, 4.2, and 5.0; targeting 4.1 so auto-port carries it forward.
