FileChannel compress fails leaving empty .gz files #865
Description
I have several applications that are all coded identically with regard to log files, but one of them is not able to compress its rotated logs correctly. All of the others compress and rotate logs correctly.
The only difference is that the program that is not rotating its logs correctly is very busy, and is logging hundreds of lines per minute. That also makes its log files much larger.
I've gone through the RotateStrategy code and the FileChannel code and have found nothing obvious.
Here is how the loggers are setup:
AutoPtr <ConsoleChannel> pCons(new ConsoleChannel);
AutoPtr <FileChannel> pChannel(new FileChannel);
AutoPtr <PatternFormatter> pPF(new PatternFormatter);
pChannel->setProperty("path", "/var/log/program.log");
pChannel->setProperty("rotation", "23:59");
pChannel->setProperty("archive", "timestamp");
pChannel->setProperty("purgeAge", "30 days");
pChannel->setProperty("times", "local");
pChannel->setProperty("compress", "true");
pPF->setProperty("times", "local");
pPF->setProperty("pattern", "%Y-%m-%d %H:%M:%S.%i %q:%s %t");
AutoPtr <FormattingChannel> pFC(new FormattingChannel(pPF, pChannel));
AutoPtr <FormattingChannel> pCC(new FormattingChannel(pPF, pCons));
AutoPtr <SplitterChannel> pSplitter(new SplitterChannel);
pSplitter->addChannel(pFC);
if (!config().getBool("application.runAsDaemon", false)) {
pSplitter->addChannel(pCC);
}
Logger::root().setChannel(pSplitter);
Logger::root().setLevel("information");As I said, I have 5 different programs all setup identically using this, with the only difference being the "path" property. 4 of the 5 rotate their logs correctly, the 5th leaves the directory looking like this:
-rw-rw-rw- 1 root root 3421175 Jun 18 15:37 csxmlsrv.log
...
-rw-rw-rw- 1 root root 17495949 Jun 16 23:58 csxmlsrv.log.20150616235908377
