33,726,802 | 0 | Destroy PHP session after set amount of time (not due to inactivity) <p>I have read numerous posts about destroying a PHP session after a set amount of time, but many of the answers don't clarify whether the solution works for inactivity or for a set period of time. Let me expound.</p> <p>I am using php to generate and grade a quiz. Each question is dynamically generated and the user must hit the submit button to move on to the next question, thereby generating a request to the php script. </p> <p>I want the user to only have 15 total minutes to complete it. In other words, if it takes the user 6 minutes to do the first 3 problems, then the user has 9 minutes left to do the other 3 problems.</p> <p>If you set your inactive time to 15 minutes, then presumably the user has 15 minutes in-between requests to the webpage, correct? <a href="http://stackoverflow.com/questions/520237/how-do-i-expire-a-php-session-after-30-minutes">This</a> is the solution that this answer provides I believe.</p> <p>However, that is not what I need. I need for the session to terminate after 15 total minutes from the start, regardless of whenever the last request was made by the user.</p> <p>Thank you</p> |

19,762,320 | 0 | <p>Firstly, what this program is doing is instantiating a new thread from within your main method that prints text to the console.</p> <p>Now, the Thread class constructor accepts a class that implements the Runnable interface. We can supply a instance to the Thread constructor two ways. We can use a concrete class that implements Runnable or supply an Anonymous Inner Class. In this case you are doing the later.</p> <p>According to the Oracle Documentation on Anonymous inner classes. Anonymous classes enable you to make your code more concise. They enable you to declare and instantiate a class at the same time. They are like local classes except that they do not have a name. Use them if you need to use a local class only once.</p> <pre><code> new Thread(new Runnable() { public void run() { System.out.print("bar"); } }).start(); </code></pre> <p>So you can think of this as passing a class of the Runnable interface which satisfies the contract by overriding the run method and defining it within the constructor parameter.</p> |

33,950,980 | 0 | <p>Right; let's see what we have here.</p> <p>First, the code has to be blocked as follows:</p> <pre><code>variable declarations cursor declarations handler declarations everything else </code></pre> <p>So your <code>DECLARE CURSOR c2</code> <em>must</em> appear between <code>DECLARE CURSOR c1</code> and <code>DECLARE CONTINUE HANDLER</code>. Also, you only need one <code>CONTINUE HANDLER</code> because it takes effect from the point of declaration to the end of the procedure.</p> <p>Next is the statement</p> <pre><code>INSERT INTO ip_ER_subtotal SELECT Starting_Pitcher, Game_Date, Game_Number, innings_pitched, 0.0 FROM starting_pitchers_game_log; </code></pre> <p>The named columns in the <code>SELECT</code> clause are the columns you're <em>selecting from,</em> <strong>not</strong> the ones you're <em>inserting into,</em> so they have to be columns in the table <code>starting_pitchers_game_log</code>. Also, since the columns not being copied from <code>starting_pitchers_game_log</code> (that is, <code>ip_total</code>, <code>er_total</code> and <code>era</code>) all have default values, you could use a column list on the <code>INSERT</code> statement, like so:</p> <pre><code>INSERT INTO pitcher_stats_temp (Starting_Pitcher, Game_Date, Game_Number, innings_pitched, er) SELECT pitcher_id, game_date, game_seq, innings_pitched, runs FROM starting_pitchers_game_log; </code></pre> <p>This saves typing, documents which columns you're actually inserting values into and insulates your <code>INSERT</code> statement from the physical order of columns in the source and target tables.</p> <p>Next, once you finish the <code>CURSOR c1</code> loop, <strong>don't truncate the table</strong> or you'll lose all the work you've just done! <code>TRUNCATE TABLE</code> deletes all rows currently in the table, and is used here to clear out the results of the previous run.</p> <p>Finally, the two loops have to have different labels, say <code>fetch_loop_1</code> and <code>fetch_loop_2</code>. You would also need to reset <code>accum</code> and <code>end_of_cursor</code> before entering the second loop. However, in this case I believe we can do everything in one loop with one cursor, which makes the code simpler and thus easier to maintain.</p> <p>Here's the complete procedure:</p> <pre><code>DROP PROCEDURE IF EXISTS pitcher_stats_era; DELIMITER $$ CREATE PROCEDURE pitcher_stats_era() BEGIN DECLARE pit_id CHAR(10); DECLARE gdate DATE; DECLARE seq INT; DECLARE in_pit REAL; DECLARE er INT; DECLARE accum_ip REAL; DECLARE accum_er INT; DECLARE earned_run_avg REAL; DECLARE prev_year YEAR(4); DECLARE end_of_cursor BOOLEAN; DECLARE no_table CONDITION FOR SQLSTATE '42S02'; DECLARE c1 CURSOR FOR SELECT pitcher_id, game_date, game_seq, innings_pitched, earned_runs FROM pitcher_stats_temp ORDER BY pitcher_id, game_date, game_seq; DECLARE CONTINUE HANDLER FOR NOT FOUND SET end_of_cursor := TRUE; DECLARE EXIT HANDLER FOR no_table BEGIN SIGNAL no_table SET MESSAGE_TEXT = "Work table not initialized. Please call pitcher_stats_reset() before continuing", MYSQL_ERRNO = 1146; END; ------------------------------------------------------------------ -- The following steps are now performed by pitcher_stats_reset() ------------------------------------------------------------------ -- TRUNCATE TABLE ip_subtotal; -- Clear our work table for a new run -- Copy data from main table into work table -- INSERT INTO ip_subtotal -- (pitcher_id, game_date, game_seq, innings_pitched, earned_runs) -- SELECT pitcher_id, game_date, game_seq, -- IFNULL(innings_pitched, 0), -- replace NULL with 0, if -- IFNULL(runs, 0) -- column not initialized -- FROM starting_pitchers_game_log; --------------------------------------------------------------------- SET end_of_cursor := FALSE; -- reset SET prev_year := 0; -- reset control-break OPEN c1; fetch_loop: LOOP FETCH c1 INTO pit_id, gdate, seq, in_pit, er; IF end_of_cursor THEN LEAVE fetch_loop; END IF; -- check control-break conditions IF YEAR(gdate) != prev_year THEN SET accum_ip := 0.0; SET accum_er := 0; SET prev_year := YEAR(gdate); END IF; SET accum_ip := accum_ip + in_pit; SET accum_er := accum_er + er; IF accum_er = 0 THEN -- prevent divide-by-zero SET earned_run_avg := 0; ELSE SET earned_run_avg := (accum_ip / accum_er) * 9; END IF; UPDATE pitcher_stats_temp SET ip_total = accum_ip, er_total = accum_er, std_era = earned_run_avg WHERE pitcher_id = pit_id AND game_date = gdate AND game_seq = seq; END LOOP; CLOSE c1; END $$ DELIMITER ; </code></pre> <p>That should do the job. If anyone finds a bug, by all means please point it out.</p> <p>EDIT: I've just added some code to illustrate how to protect against nulls coming from the source table, and how to avoid a divide-by-zero on the ERA calculation.</p> <p>EDIT: I've changed back to my original column and table names in order to reduce my own confusion.</p> <p>EDIT: Code changed to be consistent with the answer to <a href="http://stackoverflow.com/questions/33988958/how-can-i-add-a-column-to-a-work-table-using-a-new-stored-procedure">How can I add a column to a work table using a new stored procedure</a></p> |

40,420,177 | 0 | <p>There's not really well defined method of doing this - it's more of a manual task, defining how to transform the data. A form of ETL (Extract, Transform and Load) as it were.</p> <p>Start with your base tables and write some insert statements to get the core data in there, transformed as applicable. Then move onto the "next level" of related data and repeat until all of your info is copied over.</p> <p>Note that often times the new, ideal schema cannot be fully implemented (with all constraints, etc) with the legacy database as some pieces of information may be missing. In these cases you have to either a) generate the data as required during the load, or b) turn off constraints so you can load the legacy data until such data is cleaned up enough to enforce them.</p> <p>All in all, it's a very per-scenario type of thing that tends to be handled manually in most cases. To the best of my knowledge, anyway.</p> <p>Finally, it's been a while since I worked with MySQL, but most database engines allow for two-part naming of some sort, so you can access two separate databases (on the same server) from within a single script, so your insert statements might end up looking like this:</p> <pre><code>INSERT INTO newdb.newtable (thisfield, thatfield) SELECT thisfield, thatfield FROM olddb.oldtable; </code></pre> <p>(with applicable transformations applied, of course)</p> |

28,398,167 | 0 | <p>It is hard to figure out exactly what you're really asking.</p> <p>Running <code>eval()</code> on user generated content (which it appears you are doing) does bring into play all sorts of security risks because it allows user generated code to be injected right into a context that it might not normally be able to get into. That is what it is and there is nothing you can do to change it. If you're going to run arbitrary user code (no matter how you do it), you will have this risk.</p> <p>What most sites that want to run arbitrary user generated code do is they fence off the user generated code in a different domain that due to the browser's cross-origin restrictions that domain that runs user generated code cannot freely access the rest of the page that is housed in some other domain and cannot freely access your main server. This gives you some protection. Look carefully at what jsFiddle does and you will see this technique being used as the user's code is served into an iframe from <code>http://fiddle.jshell.net</code> which is different than the other frames that make the site work which comes from <code>http://jsfiddle.net</code>. jsFiddle is also using some sandbox capabilities for the iframe.</p> <p>In the newest browsers you can also set up additional cross frame security restrictions with the <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/iframe#attr-sandbox" rel="nofollow">sandbox capabilities</a> (newest generation browsers only).</p> |

You don't have to worry about creating asynchronous handlers in C#. Infact you could simply take the code on the link put into a method and use this :</p> <pre><code>YourClass c = new YourClass(); Thread thread = new Thread(c.method_to_download); thread.Start(); // continue with WinForms application. /* You can also do the following */ YourClass c = new YourClass(); c.Execute(); // where YourClass is defined as : public class YourClass() { public YourClass() {} public void Execute() { // code to execute the download in a try-catch block. } } </code></pre> <p>YourClass is a custom class that you may use to perfrom the download. It can raise a simple event optionally with arguments when the download is completed from the finally block. Your calling code can accept this event via an event handler and find out the result of the download.</p> <p>This is just two of the ways you can deal with this, there are other ways such as using a Background thread or using asynchronous callbacks with FtpWebRequest class but they all achieve the same result.</p> |

If you look at the .net class libraries or the JDK, there are collection interfaces defining methods to add or delete items, but there are unmodifiable classes implementing these interfaces. It is a good idea in this case - as you did - to provide a method to query the object if it has some capabilities, as this helps you avoid exceptions in the case that the method is not appropriate.</p> <p>OTOH, if this is an API, it might be more appropriate to use an <code>interface</code> than a <code>class</code>.</p> |

For instance, a checkbutton that is checked, onclick, will deselect for a fraction of a second, select for a second, then deselect - has anyone come across this issue and if so, is it fixable?</p> <pre><code>from Tkinter import * root = Tk() Checkbutton1 = Checkbutton(root).pack() root.mainloop() </code></pre> |
