Subject: Added a new log flag LOG_FLUSH that forces flushing the log after every
X-Git-Tag: YAZ.2.0.28~15
X-Git-Url: http://sru.miketaylor.org.uk/?a=commitdiff_plain;h=86ed958b7fd25d668f426da532a2a5c0a78bc9ef;p=yaz-moved-to-github.git

Added a new log flag LOG_FLUSH that forces flushing the log after every
write. Yaz used to do this unconditionally, now it only does if LOG_FLUSH or
LOG_DEBUG are set in the log level. Presumably speeds up stuff that writes
many log entries...
