java - Ant Freezes with no warning on exception -

-

i have been experiencing weird problem can't find solution to. when running project through ant , there's uncaught exception, ant freezes absolutely no error. here build file. multi threaded environment, also

    <fileset id="masterlibs" dir="${lib.dir}">             <patternset>                     <include name="*.jar"/>             </patternset>     </fileset>      <target name="clean">             <delete dir="${build.dir}"/>     </target>     <target name="init">             <mkdir dir="${build.dir}"/>     </target>     <target name="compile" depends="init">             <javac srcdir="${src.dir}" destdir="${build.dir}">                     <classpath>                             <pathelement location="${build.dir}"/>                             <fileset refid="masterlibs"/>                     </classpath>             </javac>     </target>      <target name="run" depends="compile">             <java classname="stockdata.alerthandler" fork="true">                     <classpath>                             <pathelement location="${build.dir}"/>                             <fileset refid="masterlibs"/>                     </classpath>                     <arg line="true"/>                     <arg line="true"/>                     <arg line="true"/>                     <arg line="true"/>                     <arg line="false"/>                     <arg line="27_4"/>                      <arg line="false"/>             </java>     </target>

ctrl+break show dump of threads , indicate each doing (plus deadlocks). i'm guessing it's spawned alerthandler process , may easier debug outside ant environment.

if ctrl+break doesn't work (from article)

on unix platforms can send signal program using kill command. quit signal, handled jvm. example, on solaris can use command kill -quit process_id, process_id process number of java program.

magically formatted comments change reported line number of javascript errors in browsers; this: //@line n "f" n line number , f file name. unfortunately, //@line appears ungoogleable. know there documentation on feature, , browsers support it?

c# - Is it possible to remove an existing registration from Autofac container builder? -

-
something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
