Quoting the Oracle® Fusion Middleware Web User Interface Developer's Guide for Oracle Application Development Framework11g Release 1 (11.1.1.4.0) documentatiom http://download.oracle.com/docs/cd/E17904_01/web.1111/b31973/ap_config.htm#BABFIGBA "When a request is sent to the server, a session timeout value is written to the page and the session timeout warning interval is defined by the context parameter  oracle.adf.view.rich.sessionHandling.WARNING_BEFORE_TIMEOUT. The user is given the opportunity to extend the session in a warning dialog, and a notification is sent when the session has expired and the page is refreshed. Depending on the application security configuration, the user may be redirected to the log in page when the session expires. Use the oracle.adf.view.rich.sessionHandling.WARNING_BEFORE_TIMEOUT context parameter to set the number of seconds prior to the session time out when a warning dialog is displayed. If the value of WARNING_BEFORE_TIMEOUT is less than 120 seconds, if client state saving is used for the page, or if the session has been invalidated, the feature is disabled. The session time-out value it taken directly from the session. Example A-3 shows configuration of the warning dialog to display at 120 seconds before the time-out of the session. Example A-3 Configuration of Session Time-out Warning <context-param>    <param-name>        oracle.adf.view.rich.sessionHandling.WARNING_BEFORE_TIMEOUT   </param-name>    <param-value>120</param-value> </context-param> The default value of this parameter is 120 seconds. To prevent notification of the user too frequently when the session time-out is set too short, the actual value of WARNING_BEFORE_TIMEOUT is determined dynamically, where the session time-out must be more than 2 minutes or the feature is disabled.

  • Hibernate - query caching/second level cache does not work by value object containing subitems

    - by Zoltan Hamori
    Hi! I have been struggling with the following problem: I have a value object containing different panels. Each panel has a list of fields. Mapping: <class name="com.aviseurope.core.application.RACountryPanels" table="CTRY" schema="DBDEV1A" where="PEARL_CTRY='Y'" lazy="join"> <cache usage="read-only"/> <id name="ctryCode"> <column name="CTRY_CD_ID" sql-type="VARCHAR2(2)" not-null="true"/> </id> <bag name="panelPE" table="RA_COUNTRY_MAPPING" fetch="join" where="MANDATORY_FLAG!='N'"> <key column="COUNTRY_LOCATION_ID"/> <many-to-many class="com.aviseurope.core.application.RAFieldVO" column="RA_FIELD_MID" where="PANEL_ID='PE'"/> </bag> </class> I use the following criteria to get the value object: Session m_Session = HibernateUtil.currentSession(); m_Criteria = m_Session.createCriteria(RACountryPanels.class); m_Criteria.add(Expression.eq("ctryCode", p_Country)); m_Criteria.setCacheable(true); As I see the query cache contains only the main select like select * from CTRY where ctry_cd_id=? Both RACountryPanels and RAFieldVO are second level cached. If I check the 2nd level cache content I can see that it cointains the RAFields and the RACountryPanels as well and I can see the select .. from CTRY where ctry_cd_id=... in query cache region as well. When I call the servlet it seems that it is using the cache, but second time not. If I check the content of the cache using JMX, everything seems to be ok, but when I measure the object access time, it seems that it does not always use the cache. Cheers Zoltan

  • Warning and error information in stored procedures revisited

    - by user13334359
    Originally way to handle warnings and errors in MySQL stored routine was designed as follows: if warning was generated during stored routine execution which has a handler for such a warning/error, MySQL remembered the handler, ignored the warning and continued execution after routine is executed MySQL checked if there is a remembered handler and activated if any This logic was not ideal and causes several problems, particularly: it was not possible to choose right handler for an instruction which generated several warnings or errors, because only first one was chosen handling conditions in current scope messed with conditions in different there were no generated warning/errors in Diagnostic Area that is against SQL Standard. First try to fix this was done in version 5.5. Patch left Diagnostic Area intact after stored routine execution, but cleared it in the beginning of each statement which can generate warnings or to work with tables. Diagnostic Area checked after stored routine execution.This patch solved issue with order of condition handlers, but lead to new issues. Most popular was that outer stored routine could see warnings which should be already handled by handler inside inner stored routine, although latest has handler. I even had to wrote a blog post about it.And now I am happy to announce this behaviour changed third time.Since version 5.6 Diagnostic Area cleared after instruction leaves its handler.This lead to that only one handler will see condition it is supposed to proceed and in proper order. All past problems are solved.I am happy that my old blog post describing weird behaviour in version 5.5 is not true any more.

  • How to clear the entire second level cache in NHibernate

    - by Bittercoder
    I wish to clear the entire second level cache in NHibernate via code. Is there a way to do this which is independent of the cache provider being used? (we have customers using both memcache and syscache within the same application). We wish to clear the entire cache because changes external the database would have occurred (which we have no guarantees re: which tables/entities were affected).

  • Eclipse - How to show warning for unused method parameter ?

    - by Brad
    I am using Eclipse v3.5. In previous Eclipse versions i remember if i have defined a method with a parameter and didn't use it internally a warning appears, like this : public void myMethod( int x ) { // Didn't use x here so a warning appears at the x parameter. } But in v3.5 i do not see this warning. How can i enable it in Eclipse ?

  • How do I generate a level randomly?

    - by Charlton Santana
    I am currently hard coding 10 different instances like the code below, but but I'd like to create many more. Instead of having the same layout for the new level, I was wondering if there is anyway to generate a random X value for each block (this will be how far into the level it is). A level 100,000 pixels wide would be good enough but if anyone knows a system to make the level go on and on, I'd like to know that too. This is basically how I define a block now (with irrelevant code removed): block = new Block(R.drawable.block, 400, platformheight); block2 = new Block(R.drawable.block, 600, platformheight); block3 = new Block(R.drawable.block, 750, platformheight); The 400 is the X position, which I'd like to place randomly through the level, the platformheight variable defines the Y position which I don't want to change.

  • Accessibility bus warning when opening files in Eclipse from command line (Ubuntu 13.10)

    - by Reese
    Similar to closed issue Gnome Menu Broken? When opening a file from the command line for edits in Eclipse , I get this warning: ** (eclipse:nnnn): WARNING **: Couldn't register with accessibility bus: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. The 4-digit number at (eclipse:nnnn) changes each time I issue an 'eclipse some/file.ext' command. The file opens but the warning is an annoyance that shouldn't be happening, it may be indicative of some other problem. Updated Ubuntu 13.10 64-bit, updated Eclipse Luna.

  • JPA/Hibernate and MySQL transaction isolation level

    - by armandino
    I have a native query that does a batch insert into a MySQL database: String sql = "insert into t1 (a, b) select x, y from t2 where x = 'foo'"; EntityTransaction tx = entityManager.getTransaction(); try { tx.begin(); int rowCount = entityManager.createNativeQuery(sql).executeUpdate(); tx.commit(); return rowCount; } catch(Exception ex) { tx.rollback(); log.error(...); } This query causes a deadlock: while it reads from t2 with insert .. select, another process tries to insert a row into t2. I don't care about the consistency of reads from t2 when doing an insert .. select and want to set the transaction isolation level to READ_UNCOMMITTED. How do I go about setting it in JPA backed by Hibernate?

  • Higher than high-level web frameworks or CMS's?

    - by Ben
    I'm looking for options that allow very high-level web site development with these special characteristics: not requiring the user to program in a complex programming language not requiring the user to use GUI-like administration areas allow the user to "program" in a lightweight markup language The last point is not only about look and structure of the output but also about creating simple dynamic output. For example: listing pages fetching the content of other pages doing a site search and displaying its output dynamically show or hide parts of the page depending on login status Of course, I am not expecting a solution that provides the same possibilities like a Ruby, Python or PHP web framework. Rather I am looking for support of the "basics" that are common for web sites. Until now, I have found only one piece of software that fulfills these requirements but while it's free, it's not open source: BoltWire at http://www.boltwire.com/. Being open source is required.

  • Should mock objects for tests be created at a high or low level

    - by Danack
    When creating unit tests for those other objects, what is the best way to create mock objects that provide data to other objects. Should they be created at a 'high level' and intercept the calls as soon as possible, or should they be done at a 'low level' and so make as much as the real code still be called? e.g. I'm writing a test for some code that requires a NoteMapper object that allows Notes to be loaded from the DB. class NoteMapper { function getNote($sqlQueryFactory, $noteID) { // Create an SQL query from $sqlQueryFactory // Run that SQL // if null // return null // else // return new Note($dataFromSQLQuery) } } I could either mock this object at a high level by creating a mock NoteMapper object, so that there are no calls to the SQL at all e.g. class MockNoteMapper { function getNote($sqlQueryFactory, $noteID) { //$mockData = {'Test Note title', "Test note text" } // return new Note($mockData); } } Or I could do it at a very low level, by creating a MockSQLQueryFactory that instead of actually querying the database just provides mock data back, and passing that to the current NoteMapper object. It seems that creating mocks at a high level would be easier in the short term, but that in the long term doing it at a low level would be more powerful and possibly allow more automation of tests e.g. by recording data in an out of a DB and then replaying that data for tests. Is there a recommended way of creating mocks? Are there any hard and fast rules about which are better, or should they both be used where appropriate?

  • Random generation of interesting puzzle levels?

    - by monsterfarm
    I'm making a Sokoban-like game i.e. there's a grid that has some crates on it you can push and you have to get the crates on crosses to win the level (although I'm going to add some extra elements to it). Are there any general algorithms or reading material I can look at for how I could go about generating interesting (as in, not trivial to solve) levels for this style of game? I'm aware that random level generators exist for Sokoban but I'm having trouble finding the algorithm descriptions. I'm interested in making a game where the machine can generate lots of levels for me, sorted by difficulty. I'm even willing to constrain the rules of the game to make the level generation easier (e.g. I'll probably limit the grid size to about 7x7). I suspect there are some general ways to do level generation here as I've seen e.g. Traffic Jam-like games (where you have to move blocks around the free some block) with 1000s of levels where each one has a unique solution. One idea I had was to generate a random map in its final state (i.e. where all crates are on top of their crosses) and then the computer would pull (instead of push) these crates around to create a level. The nice property here is that we know the level is solvable. However, I'd need some heuristics to ensure the level was interesting.

  • Collections not read from hibernate/ehcache second-level-cache

    - by Mark van Venrooij
    I'm trying to cache lazy loaded collections with ehcache/hibernate in a Spring project. When I execute a session.get(Parent.class, 123) and browse through the children multiple times a query is executed every time to fetch the children. The parent is only queried the first time and then resolved from the cache. Probably I'm missing something, but I can't find the solution. Please see the relevant code below. I'm using Spring (3.2.4.RELEASE) Hibernate(4.2.1.Final) and ehcache(2.6.6) The parent class: @Entity @Table(name = "PARENT") @Cacheable @Cache(usage = CacheConcurrencyStrategy.READ_WRITE, include = "all") public class ServiceSubscriptionGroup implements Serializable { /** The Id. */ @Id @Column(name = "ID") private int id; @OneToMany(fetch = FetchType.LAZY, mappedBy = "parent") @Cache(usage = CacheConcurrencyStrategy.READ_WRITE) private List<Child> children; public List<Child> getChildren() { return children; } public void setChildren(List<Child> children) { this.children = children; } @Override public boolean equals(Object o) { if (this == o) return true; if (o == null || getClass() != o.getClass()) return false; Parent that = (Parent) o; if (id != that.id) return false; return true; } @Override public int hashCode() { return id; } } The child class: @Entity @Table(name = "CHILD") @Cacheable @Cache(usage = CacheConcurrencyStrategy.READ_WRITE, include = "all") public class Child { @Id @Column(name = "ID") private int id; @ManyToOne(fetch = FetchType.LAZY, cascade = CascadeType.ALL) @JoinColumn(name = "PARENT_ID") @Cache(usage = CacheConcurrencyStrategy.READ_WRITE) private Parent parent; public int getId() { return id; } public void setId(final int id) { this.id = id; } private Parent getParent(){ return parent; } private void setParent(Parent parent) { this.parent = parent; } @Override public boolean equals(final Object o) { if (this == o) { return true; } if (o == null || getClass() != o.getClass()) { return false; } final Child that = (Child) o; return id == that.id; } @Override public int hashCode() { return id; } } The application context: <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="annotatedClasses"> <list> <value>Parent</value> <value>Child</value> </list> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.SQLServer2008Dialect</prop> <prop key="hibernate.hbm2ddl.auto">validate</prop> <prop key="hibernate.ejb.naming_strategy">org.hibernate.cfg.ImprovedNamingStrategy</prop> <prop key="hibernate.connection.charSet">UTF-8</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.format_sql">true</prop> <prop key="hibernate.use_sql_comments">true</prop> <!-- cache settings ehcache--> <prop key="hibernate.cache.use_second_level_cache">true</prop> <prop key="hibernate.cache.use_query_cache">true</prop> <prop key="hibernate.cache.region.factory_class"> org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory</prop> <prop key="hibernate.generate_statistics">true</prop> <prop key="hibernate.cache.use_structured_entries">true</prop> <prop key="hibernate.cache.use_query_cache">true</prop> <prop key="hibernate.transaction.factory_class"> org.hibernate.engine.transaction.internal.jta.JtaTransactionFactory</prop> <prop key="hibernate.transaction.jta.platform"> org.hibernate.service.jta.platform.internal.JBossStandAloneJtaPlatform</prop> </props> </property> </bean> The testcase I'm running: @Test public void testGetParentFromCache() { for (int i = 0; i <3 ; i++ ) { getEntity(); } } private void getEntity() { Session sess = sessionFactory.openSession() sess.setCacheMode(CacheMode.NORMAL); Transaction t = sess.beginTransaction(); Parent p = (Parent) s.get(Parent.class, 123); Assert.assertNotNull(p); Assert.assertNotNull(p.getChildren().size()); t.commit(); sess.flush(); sess.clear(); sess.close(); } In the logging I can see that the first time 2 queries are executed getting the parent and getting the children. Furthermore the logging shows that the child entities as well as the collection are stored in the 2nd level cache. However when reading the collection a query is executed to fetch the children on second and third attempt.

  • Adapting a HTML/CSS dropdown menu to multi-level

    - by Adam Nygate
    Ive been trying to make the original dropdown into multi level for a site im working on. All of my attempts have failed (. For some reason i can only do "margin-right" to align the elements, and this causes some problems. I think it has something to do with the position attribute. Here is my HTML: <ol id="nav"> <li><a href="index.php">Home</a></li> <li class="dropdown_alignedLeft"> <a href="">Products</a> <ul><li class="dropdown_alignedRight"> <a href="">iPoP</a> <ul style="margin-right:-400px; top:0px;-webkit-border-top-right-radius: 5px;border-top-right-radius: 5px;-moz-border-radius-topright: 5px;"><li><a href="customers.php?category=ipop">iPoP - Network Solutions for Vessels</a></li></ul><li class="dropdown_alignedRight"> <a href="">Cameras</a> <ul style="margin-right:-400px; top:0px;-webkit-border-top-right-radius: 5px;border-top-right-radius: 5px;-moz-border-radius-topright: 5px;"><li><a href="customers.php?category=icam">iCam 501 Ultra - Intrinsically Safe Digital Camera with Flash</a></li></ul><li class="dropdown_alignedRight"> <a href="">BNWAS</a> <ul style="margin-right:-400px; top:0px;-webkit-border-top-right-radius: 5px;border-top-right-radius: 5px;-moz-border-radius-topright: 5px;"><li><a href="customers.php?category=bnwas">BNWAS - Bridge Navigation Watch Alarm System</a></li></ul><li class="dropdown_alignedRight"> <a href="">Lighting</a> <ul style="margin-right:-400px; top:0px;-webkit-border-top-right-radius: 5px;border-top-right-radius: 5px;-moz-border-radius-topright: 5px;"><li><a href="customers.php?category=peli">Peli 2690 - Intrinsically Safe LED Head Lamp</a></li></ul><li class="dropdown_alignedRight"> <a href="">Communication</a> <ul style="margin-right:-400px; top:0px;-webkit-border-top-right-radius: 5px;border-top-right-radius: 5px;-moz-border-radius-topright: 5px;"><li><a href="customers.php?category=handy">Ex-Handy 06 - Intrinsically Safe Cell Phone</a></li></ul> </ul> <li class="dropdown_alignedLeft"> <a href="">Customers</a> <ul> <li><a href="customers.php?category=maritime">Maritime</a></li> <li><a href="customers.php?category=non">Non-Maritime</a></li> <li class="dropdown_lastItem"><a href="customers.php?category=organizations">Regulatory Organizations</a></li> </ul> <li><a href="order.php">Product Enquiry</a></li> <li><a href="contact.php">Contact Us</a></li> <li class="dropdown_alignedLeft"> <a href="">Company</a> <ul> <!-- <li><a href="">About Us</a></li> --> <li><a href="newsandpr.php?category=News">News</a></li> <li class="dropdown_lastItem"><a href="newsandpr.php?category=Press Release">Press Releases</a></li> </ul> </ol> And my CSS: #nav { float:right; margin:15px 0 0; } #nav li { float:left; } #nav li a { display:block; font-family:"PT Sans","Helvetica Neue",Arial,sans-serif; font-size:16px; text-decoration:none; color:#2B95C8; padding:10px 20px 20px; } .dropdown_alignedLeft,.dropdown_alignedRight { position:relative; } #nav .dropdown_alignedLeft>a,#nav .dropdown_alignedRight>a { background:url(../images/dropdown_arrow_blue.png) no-repeat top right; padding:10px 30px 20px 20px; } #nav .dropdown_alignedLeft:hover>a,#nav .dropdown_alignedRight:hover>a { -moz-border-radius-topleft:5px; -moz-border-radius-topright:5px; -moz-border-radius-bottomright:0; -moz-border-radius-bottomleft:0; -webkit-border-top-left-radius:5px; -webkit-border-top-right-radius:5px; -webkit-border-bottom-right-radius:0; -webkit-border-bottom-left-radius:0; border-top-left-radius:5px; border-top-right-radius:5px; border-bottom-right-radius:0; border-bottom-left-radius:0; color:#FFF; background:#2378A1 url(../images/dropdown_arrow_blue.png) no-repeat bottom right; } .dropdown_alignedLeft ul,.dropdown_alignedRight ul { display:none; } #nav .dropdown_alignedLeft:hover>ul,#nav .dropdown_alignedRight:hover>ul { display:block; z-index:100; position:absolute; top:50px; -moz-border-radius-topleft:0; -moz-border-radius-topright:0; -moz-border-radius-bottomright:5px; -moz-border-radius-bottomleft:5px; -webkit-border-top-left-radius:0; -webkit-border-top-right-radius:0; -webkit-border-bottom-right-radius:5px; -webkit-border-bottom-left-radius:5px; border-top-left-radius:0; border-top-right-radius:0; border-bottom-right-radius:5px; border-bottom-left-radius:5px; background:#2378A1; padding:0 0 6px; } #nav .dropdown_alignedRight:hover>ul { top:50px; right:0; text-align:right; } #nav li ul li { float:none; border-bottom:1px dashed #2B95C8; margin:0 20px; } #nav li ul li.dropdown_innerTitle { border:none; font-family:"Helvetica Neue",Arial,sans-serif; font-size:15px; white-space:nowrap; color:#C8DDE7; margin:10px 20px 0; padding:10px 0; } #nav li ul li.dropdown_lastItem { border:none; } #nav li ul li a { font-family:"Helvetica Neue",Arial,sans-serif; font-size:13px; color:#FFF; white-space:nowrap; padding:10px 0 9px; } #nav>li:hover>a,#nav li .current_page { color:#2378A1; background:url(../images/current_page_arrow_blue.png) no-repeat center bottom; } #nav li ul li a:hover { color: #C8DDE7; } For a live version of the menu, please go here: JSFiddle - Live Menu

  • Java Logger API

    - by Koppar
    This is a more like a tip rather than technical write up and serves as a quick intro for newbies. The logger API helps to diagnose application level or JDK level issues at runtime. There are 7 levels which decide the detailing in logging (SEVERE, WARNING, INFO, CONFIG, FINE, FINER, FINEST). Its best to start with highest level and as we narrow down, use more detailed logging for a specific area. SEVERE is the highest and FINEST is the lowest. This may not make sense until we understand some jargon. The Logger class provides the ability to stream messages to an output stream in a format that can be controlled by the user. What this translates to is, I can create a logger with this simple invocation and use it add debug messages in my class: import java.util.logging.*; private static final Logger focusLog = Logger.getLogger("java.awt.focus.KeyboardFocusManager"); if (focusLog.isLoggable(Level.FINEST)) { focusLog.log(Level.FINEST, "Calling peer setCurrentFocusOwner}); LogManager acts like a book keeper and all the getLogger calls are forwarded to LogManager. The LogManager itself is a singleton class object which gets statically initialized on JVM start up. More on this later. If there is no existing logger with the given name, a new one is created. If there is one (and not yet GC’ed), then the existing Logger object is returned. By default, a root logger is created on JVM start up. All anonymous loggers are made as the children of the root logger. Named loggers have the hierarchy as per their name resolutions. Eg: java.awt.focus is the parent logger for java.awt.focus.KeyboardFocusManager etc. Before logging any message, the logger checks for the log level specified. If null is specified, the log level of the parent logger will be set. However, if the log level is off, no log messages would be written, irrespective of the parent’s log level. All the messages that are posted to the Logger are handled as a LogRecord object.i.e. FocusLog.log would create a new LogRecord object with the log level and message as its data members). The level of logging and thread number are also tracked. LogRecord is passed on to all the registered Handlers. Handler is basically a means to output the messages. The output may be redirected to either a log file or console or a network logging service. The Handler classes use the LogManager properties to set filters and formatters. During initialization or JVM start up, LogManager looks for logging.properties file in jre/lib and sets the properties if the file is provided. An alternate location for properties file can also be specified by setting java.util.logging.config.file system property. This can be set in Java Control Panel ? Java ? Runtime parameters as -Djava.util.logging.config.file = <mylogfile> or passed as a command line parameter java -Djava.util.logging.config.file = C:/Sunita/myLog The redirection of logging depends on what is specified rather registered as a handler with JVM in the properties file. java.util.logging.ConsoleHandler sends the output to system.err and java.util.logging.FileHandler sends the output to file. File name of the log file can also be specified. If you prefer XML format output, in the configuration file, set java.util.logging.FileHandler.formatter = java.util.logging.XMLFormatter and if you prefer simple text, set set java.util.logging.FileHandler.formatter =java.util.logging.SimpleFormatter Below is the default logging Configuration file: ############################################################ # Default Logging Configuration File # You can use a different file by specifying a filename # with the java.util.logging.config.file system property. # For example java -Djava.util.logging.config.file=myfile ############################################################ ############################################################ # Global properties ############################################################ # "handlers" specifies a comma separated list of log Handler # classes. These handlers will be installed during VM startup. # Note that these classes must be on the system classpath. # By default we only configure a ConsoleHandler, which will only # show messages at the INFO and above levels. handlers= java.util.logging.ConsoleHandler # To also add the FileHandler, use the following line instead. #handlers= java.util.logging.FileHandler, java.util.logging.ConsoleHandler # Default global logging level. # This specifies which kinds of events are logged across # all loggers. For any given facility this global level # can be overriden by a facility specific level # Note that the ConsoleHandler also has a separate level # setting to limit messages printed to the console. .level= INFO ############################################################ # Handler specific properties. # Describes specific configuration info for Handlers. ############################################################ # default file output is in user's home directory. java.util.logging.FileHandler.pattern = %h/java%u.log java.util.logging.FileHandler.limit = 50000 java.util.logging.FileHandler.count = 1 java.util.logging.FileHandler.formatter = java.util.logging.XMLFormatter # Limit the message that are printed on the console to INFO and above. java.util.logging.ConsoleHandler.level = INFO java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter ############################################################ # Facility specific properties. # Provides extra control for each logger. ############################################################ # For example, set the com.xyz.foo logger to only log SEVERE # messages: com.xyz.foo.level = SEVERE Since I primarily use this method to track focus issues, here is how I get detailed awt focus related logging. Just set the logger name to java.awt.focus.level=FINEST and change the default log level to FINEST. Below is a basic sample program. The sample programs are from http://www2.cs.uic.edu/~sloan/CLASSES/java/ and have been modified to illustrate the logging API. By changing the .level property in the logging.properties file, one can control the output written to the logs. To play around with the example, try changing the levels in the logging.properties file and notice the difference in messages going to the log file.

  • Clang warning flags for Objective-C development

    - by Macmade
    As a C & Objective-C programmer, I'm a bit paranoid with the compiler warning flags. I usually try to find a complete list of warning flags for the compiler I use, and turn most of them on, unless I have a really good reason not to turn it on. I personally think this may actually improve coding skills, as well as potential code portability, prevent some issues, as it forces you to be aware of every little detail, potential implementation and architecture issues, and so on... It's also in my opinion a good every day learning tool, even if you're an experienced programmer. For the subjective part of this question, I'm interested in hearing other developers (mainly C, Objective-C and C++) about this topic. Do you actually care about stuff like pedantic warnings, etc? And if yes or no, why? Now about Objective-C, I recently completely switched to the LLVM toolchain (with Clang), instead of GCC. On my production code, I usually set this warning flags (explicitly, even if some of them may be covered by -Wall): -Wall -Wbad-function-cast -Wcast-align -Wconversion -Wdeclaration-after-statement -Wdeprecated-implementations -Wextra -Wfloat-equal -Wformat=2 -Wformat-nonliteral -Wfour-char-constants -Wimplicit-atomic-properties -Wmissing-braces -Wmissing-declarations -Wmissing-field-initializers -Wmissing-format-attribute -Wmissing-noreturn -Wmissing-prototypes -Wnested-externs -Wnewline-eof -Wold-style-definition -Woverlength-strings -Wparentheses -Wpointer-arith -Wredundant-decls -Wreturn-type -Wsequence-point -Wshadow -Wshorten-64-to-32 -Wsign-compare -Wsign-conversion -Wstrict-prototypes -Wstrict-selector-match -Wswitch -Wswitch-default -Wswitch-enum -Wundeclared-selector -Wuninitialized -Wunknown-pragmas -Wunreachable-code -Wunused-function -Wunused-label -Wunused-parameter -Wunused-value -Wunused-variable -Wwrite-strings I'm interested in hearing what other developers have to say about this. For instance, do you think I missed a particular flag for Clang (Objective-C), and why? Or do you think a particular flag is not useful (or not wanted at all), and why?
