annotate src/master/login-process.c @ 2000:c7c19f5071c3 HEAD

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Write all logging through master process. Fixes problems with log rotation, chrooting, etc. Master process also allows max. 10 log messages per second per child process, it then begins throttling them (eventually making the child process start blocking on stderr).
