With the vast number of log debug statements in the code, the logging framework has a measurable performance impact on libvirt code, particularly in the daemon event loop. The global log buffer records every single log message triggered whether anyone cares to see them or not. This makes it impossible to eliminate the overhead of printf format expansions in any of the logging code. It is possible to disable the global log buffer in libvirtd itself, but this doesn't help client side library code. Also even if disabled by the config file, the existance of the feature makes other performance improvements in the logging layer impossible. Instead of logging every single message to the global buffer, only log messages that pass the log filters. This if libvirtd is set to have log_filters="1:libvirt 1:qemu" the global log buffer will only get filled with those messages instead of everything. This reduces the performance burden, as well as improving the signal to noise ratio of the log buffer. As a quick benchmark, a demo program that registers 500 file descriptors with the event loop (eg equiv of 500 QEMU monitor commands), creates pending read I/O on every FD, and then runs virEventRunDefaultImpl() took 1 minute 40 seconds todo 51200 iterations with nearly all the time shown against the logging code. After this optimization it only takes 4.6 seconds. Signed-off-by: Daniel P.

The virRaiseErrorFull method sends all error messages onto the logging code. The logging code has some logic to skip emission when no log outputs are configured which checks the virLogSource. This will complicate later refactoring, and the check can easily be done in the virRaiseErrorFull method instead of in the logging code. Signed-off-by: Daniel P.

The dtrace probe macros rely on the logging API. We can't make the internal.h header include the virlog.h header though since that'd be a circular include. Instead simply split the dtrace probes into their own header file, since there's no compelling reason for them to be in the main internal.h header. Signed-off-by: Daniel P.

As part of the goal to get away from doing string matching on filenames when deciding whether to emit a log message, turn the virLogSource enum into a struct which contains a log "name". There will eventually be one virLogSource instance statically declared per source file. To minimise churn in this commit though, a single global instance is used. Signed-off-by: Daniel P.

Currently the log filter strings are used in a string comparison against the source filename each time log message is emitted. If no log filters at all are set, there's obviously no string comparison to be done. If any single log filter is set though, this imposes a compute burden on every logging call even if logs from the file in question are disabled. This string comparison must also be done while the logging mutex is held, which has implications for concurrency when multiple threads are emitting log messages. This changes the log filtering to be done baed on the virLogSource object name. The virLogSource struct is extended to container 'serial' and 'priority' fields. Any time the global log filter rules are changed a global serial number is incremented. When a log message is emitted, the serial in the virLogSource instance is compared with the global serial number. If out of date, then the 'priority' field in the virLogSource instance is updated based on the new filter rules. The 'priority' field is checked to see whether the log message should be sent to the log outputs. The comparisons of the 'serial' and 'priority' fields are done with no locks held. So in the common case each logging call has an overhead of 2 integer comparisons, with no locks held. Only if the decision is made to forward the message to the log output, or if the 'serial' value is out of date do locks need to be acquired. Technically the comparisons of the 'serial' and 'priority' fields should be done with locks held, or using atomic operations. Both of these options have a notable performance impact, however, and it is believed that worst case behaviour where the fields are read concurrently with being written would merely result in an mistaken emissions or dropping of the log message in question. This is an acceptable tradeoff for the performance benefit of avoiding locking. As a quick benchmark, a demo program that registers 500 file descriptors with the event loop (eg equiv of 500 QEMU monitor commands), creates pending read I/O on every FD, and then runs virEventRunDefaultImpl() took 4.6 seconds todo 51200 iterations. After this optimization it only takes 3.3 seconds, with the log APIs no longer being a relevant factor in the running time. Signed-off-by: Daniel P.

A earlier commit changed the global log buffer so that it only records messages that are explicitly requested via the log filters setting. This removes the performance burden, and improves the signal/noise ratio for messages in the global buffer. At the same time though, it is somewhat pointless, since all the recorded log messages are already going to be sent to an explicit log output like syslog, stderr or the journal. The global log buffer is thus just duplicating this data on stderr upon crash. Signed-off-by: Daniel P.
