Initializing Thread names using the Thread constructor parameter is
faster as it already sets a thread name even if no customized one is
given, while an additional call to the Thread.setName() function
internally do synchronized access, eventually runs access check on the
security manager and performs a native call.
Profiling a running YaCy server revealed that the total processing time
spent on Thread.setName() for a typical p2p search was in the range of
seconds.
Especially for Turkish speaking users using "tr" as their system default
locale : strings for technical stuff (URLs, tag names, constants...)
must not be lower cased with the default locale, as 'I' doesn't becomes
'i' like in other locales such as "en", but becomes 'ı'.
Also add when possible a warning level log message on input stream
closing error instead of failing silently. This could help understanding
some IO exceptions such as "too many files open".
First fix for mantis 689 (http://mantis.tokeek.de/view.php?id=689).
On Debian Linux, with a headless jre and no open browser,
browser.openBrowserClassic() was called and waited forever the browser
process end (p.waitFor()). YaCy shutdown was therefore not working until
the browser was closed.
Also modified browser opening command for Unix platform to open the
default the browser (with xdg-open util) instead of Firefox.
xdg-open also has the advantage to be asynchronous (not blocking).
script. Adopted the YaCyApp environment and fixed a problem in the
startYACY.sh application wrapper which caused wrong usage of logging
option -l which caused that files had been written to the YaCy
application folder.
As a result of this fix, it is not necessary any more to change path
settings in Info.plist if libraries are changed.
*) will try other ports if YaCy standard ports are not available
*) distinguish between internal and external port (not sure if this
works 100%)
Still to add: propery in config to enter own external port (in case of
manually configured NAT)
jdk-based logger tend to block
at java.util.logging.Logger.log(Logger.java:476) in concurrent
environments. This makes logging a main performance issue. To overcome
this problem, this is a add-on to jdk logging to put log entries on a
concurrent message queue and log the messages one by one using a
separate process.
- FTPClient uses the concurrent logging instead of the log4j logger
- if YaCy is started with the option -gui, it is not in headless mode. Then the java 1.6 browse method is used if all other methods fail
- in linux, the path /etc/alternatives/www-browser is used if no firefox is installed
