RotateFileNoCompression

Happy New Year to everybody!

The TSynLog.Family has the RotateFileNoCompression property in the mORMot1 but I have not found any analogue in the mORMot2.

Is there a way to rotate old logs without compression in mORMot2?

Re: RotateFileNoCompression

You need to use the LogCompressAlgo global variable.
If you set it to nil, no compression will take place.

I have refined the documentation about LogCompressAlgo

Unfortunately, this does not work:  empty {LogName}.#.synlz files are created.

It looks like I have to either write a custom OnRotate handler, or write a "dummy" TAlgoCompress inherited class and assign its name to LogCompressAlgo.

Re: RotateFileNoCompression

Are you sure you have the latest version of the source?

TSynLog.PerformRotation clearly checks LogCompressAlgo, and if nil, won't use AlgoFileExt and call RenameFile() without any compression, using a {logName}.#.log rotation file.

My fault! I had not pulled the latest version.
