Sriram R updated LOG4J2-3313:
-----------------------------
Description:
Let us take an example where we have a RollingFile
appender with a DefaultRollOverStrategy.
Let's consider the following values for
{code:java}
fileName = "logs/test.log"
filePattern = "logs/%d{yyyy-MM-dd}/test-%d{yyyy-MM-dd-HH-mm}.%i.log.gz" {code}
When a rollover takes place, log4j2 first renames test.log and moves it to the
filePattern
path, and then compresses the file
{code:java}
[ logs/test.log -> logs/2022-01-03/test-2021-01-03-01.1.log ->
logs/2022-01-03/test-2021-01-03-01.1.log.gz{code}
Now let's consider a scenario where we also use tempCompressedFilePattern with
DefaultRolloverStrategy.
{code:java}
tempCompressedFilePattern =
"tmp/%d{yyyy-MM-dd}/test-%d{yyyy-MM-dd-HH-mm}.%i.log.gz" {code}
In this scenario, I would expect test.log to be renamed and moved to `tmp`
folder before being compressed but that's not the case
IDEAL SCENARIO
{code:java}
logs/test.log -> tmp/2021-01-03/test-2022-01-03-01.log ->
tmp/test-2022-01-03-01.log.gz -> logs/2021-01-03/test-2022-01-03-01.log.gz{code}
But this happens [ difference in step2 from IDEAL SCENARIO ]
{code:java}
logs/test.log -> logs/2021-01-03/test-2022-01-03-01.log ->
tmp/test-2022-01-03-01.log.gz -> logs/2021-01-03/test-2022-01-03-01.log.gz{code}
Here, even though the temp pattern folder is different, a temporary file is
created in the destination which is then moved to tmp path.
