Pull request overview
This PR aims to reduce duplicate ERROR log entries emitted by DefaultStackTraceFilterer by filtering stack traces for the full exception cause-chain without logging each cause separately, and logging the full stack trace only once for the top-level exception.
Changes:
- Extracted the filtering/trimming logic into a new private
doFilter(Throwable)method. - Updated recursive filtering to call
doFilter(...)when walking the cause chain. - Updated
filter(Throwable)to log conditionally (intended: once per top-level exception).
Comments suppressed due to low confidence (1)
grails-bootstrap/src/main/groovy/org/grails/exceptions/reporting/DefaultStackTraceFilterer.java:88
- In
filter(Throwable source, boolean recursive), the recursive walk callsdoFilter(current)starting withcurrent = source, and thenfilter(source)is invoked afterward. This filters the top-level exception twice and, more importantly, ensures the later log infilter(source)will observe an already-filtered stack trace. Consider starting the loop atsource.getCause()(filter causes only) so the top-level exception is filtered/logged exactly once infilter(source).
public Throwable filter(Throwable source, boolean recursive) {
if (recursive) {
Throwable current = source;
while (current != null) {
doFilter(current);
current = current.getCause();
}
}
return filter(source);

filter(Throwable source) currently calls doFilter(source) (which mutates source via setStackTrace) before logging FULL_STACK_TRACE_MESSAGE. That means the "Full Stack Trace" log is no longer the full/original trace, but the already-filtered trace. To preserve prior behavior and the PR description, log the exception before applying the filtered stack trace (e.g., have doFilter compute/return the cleaned trace without mutating, then apply after logging, or temporarily save/restore the original trace around the log call).

This change modifies when/how often the StackTrace logger logs (STACK_LOG.error(...)) during recursive filtering, but existing specs (e.g., grails-core/src/test/.../StackTraceFiltererSpec.groovy) only assert the sanitized stack trace contents and don't cover log emission/count. Adding a test that captures the StackTrace logger output and asserts a single "Full Stack Trace" entry for filter(e, true) would help prevent regressions.

Isn't this a different meaning now? Before it would have been the full stack trace while now it's the filtered. Wouldn't a better solution be to set the logging to trace or something for these detailed stack traces ? Instead of this change why not disable STACK_LOG if you don't want this output?

@jdaugherty sensible defaults. logging a stracktrace 4x that has no useful information (especially with the groovy 4 clutter) quickly leads to a scenario where you can run out of disk space fast.
I have yet to see an example where the 4x logging provides anything useful. do you have one?

The more I have thought about this, the more I realize this is not a bug fix. This is a feature - we are not trimming stacktraces that got longer due to groovy 4. We are instead hiding traces that get logged multiple times. I think the original behavior needs to stay and we need to make the new feature opt in. |

I would probably label this as a bug. Or is this behavior intentional? This is the log output when visiting package com.example
class StackTraceController {
def show() {
display()
}
private void display() {
notHere
}

- cleanup and clarify current tests - add test for logging once
Let `CountingStackTraceFilterer` call `super.filter(source)`.

I think the intent is to disable the logging on this filter, yes? Then you don't see the the full stacktraces. |

Why not change the default configuration to just hide logs from grails-bootstrap/src/main/groovy/org/grails/exceptions/reporting/DefaultStackTraceFilterer.java then there wouldn't be a duplicate log right? We also appear to have removed the cut off package, which means it could filter our own package |

Yes, that might be one option/solution! <logger name="StackTrace" level="OFF" />> <

Fix duplicate stack trace logging in DefaultStackTraceFilterer
When an exception occurs in a Grails controller, the same error is logged multiple times to the
StackTracelogger. For a typicalInvocationTargetExceptionwrapping aRuntimeException, this produces 3-4 separate ERROR log entries for a single request:StackTracelogger: Full stack trace of the wrapper exceptionStackTracelogger: Full stack trace of the root causeStackTracelogger: Full stack trace of the wrapper again (condensed)GrailsExceptionResolverlogger: The exception with request contextEntries 1-3 all come from
DefaultStackTraceFilterer.filter(). Thefilter(Throwable source, boolean recursive)method walks thecause chain and calls
filter(Throwable source)for each throwable. Butfilter(Throwable source)logs the full stack trace viaSTACK_LOG.error(FULL_STACK_TRACE_MESSAGE, source)every time it trims a trace — so each cause in the chain gets its own log entry.This is compounded by the fact that
GrailsExceptionResolver.logStackTrace()then logs the exception a final time with requestcontext. The filterer and the resolver were written independently — the filterer doesn't know the resolver will also log, and the
resolver doesn't know the filterer already logged.
Fix
Extract the stack trace trimming logic into a private
doFilter(Throwable)method that filters without logging. The recursive walkcalls
doFilter()for each cause in the chain. The publicfilter(Throwable source)method callsdoFilter()and then logs thefull stack trace once for the top-level exception (which naturally includes its causes in the log output).
This reduces the
StackTracelogger output from N entries (one per cause) to 1 entry, while preserving all existing behavior:StackTraceFiltererinterface is unchangedGrailsExceptionResolversubclasses are unaffected
