  • How to use @BeforeClass and @AfterClass in JunitPerf?

    - by allenzzzxd
    Hi, I want to do some actions before the whole test suite (also after the suite). So I wrote like: public class PerformanceTest extends TestCase { @BeforeClass public static void suiteSetup() throws Exception { //do something } @AfterClass public static void suiteSetup() throws Exception { //do something } @Before public void setUp() throws Exception { //do something } @After public void tearDown() throws Exception { //do something } public PerformanceTest(String testName){ super(testName); } public static Test suite() { TestSuite suite = new TestSuite(); Test testcase1 = new PerformanceTest("DoTest1"); Test loadTest1 = new LoadTest(testcase1, n); Test testcase2 = new PerformanceTest("DoTest2"); Test loadTest2 = new LoadTest(testcase2, n); } public void DoTest1 throws Throwable{ //do something } public void DoTest2 throws Throwable{ //do something } } But I found that it never reach the code in @BeforeClass and @AfterClass. So how could I do to solve this problem? Or is there other way to realize this? Thank you for your help.

  • Memory leak in C++ program.

    - by lampshade
    What I have is a very crude linked list..THe problem for me is that I am getting a memory leak in the constructor or main. I think it is the constructor. I have not yet deleted the eventName varaible that I have allocated memory for. Could someone help please? :/ (This is not a homework question) class Event { private: char * eventName ; string userEvent; struct node { node(); node * nextByName; const char * eventName; }; node * headByName; public: Event(const char * eventName, const Date &myDate); Event(); virtual ~Event(); void insert(const char * eventName, const Date &myDate, const Time &myTime); void setEvent(); const char * const getEvent() const { return userEvent.c_str(); }; void displayByName(ostream& out) const; }; Event::Event(const char * eventName, const Date &myDate) : eventName(new char[strlen(eventName)+1]), headByName(NULL), userEvent("") { if (eventName) { size_t length = strlen(eventName) +1; strcpy_s(this->eventName, length, eventName); } else eventName = NULL; } Event::Event() : eventName(NULL), userEvent(NULL), headByName(NULL) { } Event::~Event() { node * temp_node = NULL; node * current_node = headByName; while ( current_node ) { temp_node = current_node->nextByName; delete current_node; current_node = temp_node; } } void Event::insert(const char * eventName, const Date &myDate, const Time &myTime) // when we insert we dont care about the time, just the name and the date { node * current_node = new node(); if ( headByName == NULL ) { headByName = current_node; headByName->eventName = eventName; } else { node * search_node = headByName; node * prev_node = NULL; while ( search_node != NULL ) { prev_node = search_node; search_node = search_node->nextByName; } if ( NULL == prev_node ) { headByName = current_node; } else { prev_node->nextByName = current_node; } current_node->nextByName = search_node; current_node->eventName = eventName ; } } void Event::displayByName(ostream& out) const { cout << "Scheduled Events are: " << endl << endl; node * current_node = headByName; while ( current_node ) { (char*)eventName = (char*)current_node->eventName; out << eventName << endl; current_node = current_node->nextByName; } } Event::node::node() : nextByName(NULL), eventName(NULL) { } void Event::setEvent() { cout << "\n\nEnter a new event!

  • First and last window don't show up.

    - by SirGregg
    Hi, I'm creating a WinApi application for my programming course. The program is supposed to show an LED clock using a separate window for each 'block'. I have figured most of it out, except for one thing: when creating the two-dimensional array of windows, the first and last window never show up. Here's the piece of code from the InitInstance function: for (int x=0;x<8;x++) for (int y=0;y<7;y++) { digitWnd[x][y] = CreateWindowEx((WS_EX_LAYERED | WS_EX_TRANSPARENT | WS_EX_NOACTIVATE | WS_EX_STATICEDGE), szWindowClass, szTitle, (WS_POPUP| WS_BORDER), NULL, NULL, NULL, NULL, dummyWnd, NULL, hInstance, NULL); ShowWindow(digitWnd[x][y], nCmdShow); UpdateWindow(digitWnd[x][y]); } The same loop bounds are used everytime I interact with the windows (set position and enable/disable). All the windows seem to be working fine, except for digitWnd[0][0] and digitWnd[7][6]... Any ideas as to what is happening?

  • Regular expression replacing only if contained withing a regular expression match?

    - by Tower
    Hi, I have the following: [list] [*] test [*] test [*] test [/list] and I would like to create a regular expression that turns that into: <ul> <li>test</li> <li>test</li> <li>test</li> </ul> I know regex enough to replace simple tags, but in this case I need to replace li tags only if they are contained inside ul. Is there a way to check that before replacing? I am using JavaScript if that matters.

  • R matrix handling expressions aren't evaluated in a function or a "for" loop - Column extract doesn't seem to work

    - by Sal Leggio
    I have an R matrix named ddd. When I enter this, everything works fine: i <- 1 shapiro.test(ddd[,y]) ad.test(ddd[,y]) stem(ddd[,y]) print(y) The calls to Shapiro Wilk, Anderson Darling, and stem all work, and extract the same column. If I put this code in a "for" loop, the calls to Shapiro Wilk, and Anderson Darling stop working, while the the stem & leaf call and the print call continue to work. for (y in 7:10) { shapiro.test(ddd[,y]) ad.test(ddd[,y]) stem(ddd[,y]) print(y) } The decimal point is 1 digit(s) to the right of the | 0 | 0 0 | 899999 1 | 0 [1] 7 The same thing happens if I try and write a function. SW & AD do not work. The other calls do. D <- function (y) { + shapiro.test(ddd[,y]) + ad.test(ddd[,y]) + stem(ddd[,y]) + print(y) } D(9) The decimal point is at the | 9 | 000 9 | 10 | 00000 [1] 9 Why don't all the calls behave the same way?

  • How to remove/hide <div></div> tags only without the content?

    - by candies
    For example I have: <div id ="test">[the content here]</div> The content within the div tags will appear after I called the id of div using ajax. This is the code: function dinamic(add) { var kode = add.value; if (!kode) return; xmlhttp2.open('get', '../template/get_id.php?kode='+kode, true); xmlhttp2.onreadystatechange = function() { if ((xmlhttp2.readyState == 4) && (xmlhttp2.status == 200)) { var add = document.getElementById("test"); add.innerHTML = xmlhttp2.responseText; } return false; } xmlhttp2.send(null); } So it will appear <div id="test">A</div> I'd like to put the content of div - A into mysql query. $test = $_GET['test']; $query = "select * from example where category='$test'"; I've tried to make variable $test of the div id to get the content but result of the query in category is none. I tried again, I put the div in to the query $query = "select * from example where category='<div id=\"test\">A</div>'"; Yes, It works. But when I did query on navicat, no results I got because there's spaces between A that is <div> and </div>. How to remove/hide the div tags only so its only appear the content? > $query = "select * from example where category='A'"; < Edit: If I echo the query on firefox browser will say "$query = "select * from example where category='[space]A[space]'";" And look at the bug(I use firebug), it will say "$query = "select * from example where category='<div id="test">A</div>'";" So my guessing why can't get result after query on navicat is there's spaces between A([space]A[space]), just have no idea how to remove/hide the div tags, I want to get this result only "$query = "select * from example where category='A'";" Thanks.

  • Best practices for multiple asserts on same result in C#

    - by asdseee
    What do you think is cleanest way of doing multiple asserts on a result? In the past I've put them all the same test but this is starting to feel a little dirty, I've just been playing with another idea using setup. [TestFixture] public class GridControllerTests { protected readonly string RequestedViewId = "A1"; protected GridViewModel Result { get; set;} [TestFixtureSetUp] public void Get_UsingStaticSettings_Assign() { var dataRepository = new XmlRepository("test.xml"); var settingsRepository = new StaticViewSettingsRepository(); var controller = new GridController(dataRepository, settingsRepository); this.Result = controller.Get(RequestedViewId); } [Test] public void Get_UsingStaticSettings_NotNull() { Assert.That(this.Result,Is.Not.Null); } [Test] public void Get_UsingStaticSettings_HasData() { Assert.That(this.Result.Data,Is.Not.Null); Assert.That(this.Result.Data.Count,Is.GreaterThan(0)); } [Test] public void Get_UsingStaticSettings_IdMatches() { Assert.That(this.Result.State.ViewId,Is.EqualTo(RequestedViewId)); } [Test] public void Get_UsingStaticSettings_FirstTimePageIsOne() { Assert.That(this.Result.State.CurrentPage, Is.EqualTo(1)); } }

  • Must JDBC Resultsets and Statements be closed separately although the Connection is closed afterwards?

    - by Mulmoth
    It is said to be a good habit to close all JDBC resources after usage. But if I have the following code, is it necessary to close the Resultset and the Statement? Connection conn = null; PreparedStatement stmt = null; ResultSet rs = null; try { conn = // Retrieve connection stmt = conn.prepareStatement(// Some SQL); rs = stmt.executeQuery(); } catch { // Error Handling } finally { try { if (rs != null) rs.close(); } catch (Exception e) {}; try { if (stmt != null) stmt.close(); } catch (Exception e) {}; try { if (conn != null) conn.close(); } catch (Exception e) {}; } The question is if the closing of the connection does the job or if it leaves some resources in use.

  • Auto Generated - CREATE Table Script in SQL 2008 throws error

    - by jack
    I scripted the tables in my dev database using SQL 2008 - generate scripts option (Datbase-right click-Tasks-Generate Scripts) and ran it on the staging database, but the script throws the below error for each table Msg 102, Level 15, State 1, Line 1 Incorrect syntax near '('. Msg 319, Level 15, State 1, Line 15 Incorrect syntax near the keyword 'with'. If this statement is a common table expression, an xmlnamespaces clause or a change tracking context clause, the previous statement must be terminated with a semicolon. Below is the script for one of my table ALTER TABLE [dbo].[Customer]( [CustomerID] [int] IDENTITY(1,1) NOT NULL, [FirstName] [nvarchar](500) NULL, [LastName] [nvarchar](500) NULL, [DateOfBirth] [datetime] NULL, [EmailID] [nvarchar](200) NULL, [ContactForOffers] [bit] NULL, CONSTRAINT [PK_Customer] PRIMARY KEY CLUSTERED ( [CustomerID] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] GO Any help will be much appreciated.

  • Is there any memory leak in the normal routine of sqlite3_*()?

    - by reer
    A normal routine of sqlite3_prepare_v2() + sqlite3_step() + sqlite3_finalize() could contain leak. It sound ridiculous. But the test code seems to say it. Or I used the sqlite3_*() wrongly. Appreciate for any reply. __code________________________ include include // for usleep() include int multi_write (int j); sqlite3 *db = NULL; int main (void) { int ret = -1; ret = sqlite3_open("test.db", &db); ret = sqlite3_exec(db,"CREATE TABLE data_his (id INTEGER PRIMARY KEY, d1 CHAR(16))", NULL,NULL,NULL); usleep (100000); int j=0; while (1) { multi_write (j++); usleep (2000000); printf (" ----------- %d\n", j); } ret = sqlite3_close (db); return 0; } int multi_write (int j) { int ret = -1; char *sql_f = "INSERT OR REPLACE INTO data_his VALUES (%d, %Q)"; char *sql = NULL; sqlite3_stmt *p_stmt = NULL; ret = sqlite3_prepare_v2 (db, "BEGIN TRANSACTION", -1, &p_stmt, NULL); ret = sqlite3_step ( p_stmt ); ret = sqlite3_finalize ( p_stmt ); int i=0; for (i=0; i<100; i++) { sql = sqlite3_mprintf ( sql_f, j*100000 + i, "00000000000068FD"); ret = sqlite3_prepare_v2 (db, sql, -1, &p_stmt, NULL ); sqlite3_free ( sql ); //printf ("sqlite3_prepare_v2(): %d, %s\n", ret, sqlite3_errmsg (db)); ret = sqlite3_step ( p_stmt ); //printf ("sqlite3_step(): %d, %s\n", ret, sqlite3_errmsg (db)); ret = sqlite3_finalize ( p_stmt ); //printf ("sqlite3_finalize(): %d, %s\n\n", ret, sqlite3_errmsg (db)); } ret = sqlite3_prepare_v2 (db, "COMMIT TRANSACTION", -1, &p_stmt, NULL ); ret = sqlite3_step ( p_stmt ); ret = sqlite3_finalize ( p_stmt ); return 0; } __result________________________ And I watch the the process's run by top. At first, the memory statistics is: PID PPID USER STAT VSZ %MEM %CPU COMMAND 17731 15488 root S 1104 5% 7% ./sqlite3multiwrite When the printf() in while(1){} of main() prints the 150, the memory statistics is: PID PPID USER STAT VSZ %MEM %CPU COMMAND 17731 15488 root S 1552 5% 7% ./sqlite3multiwrite It sounds that after 150 for-cycles, the memory used by sqlite3multiwrite increase from 1104KB to 1552KB. What does it mean? memory leak or other thing?

  • Row/column counter in 'apply' functions

    - by mortalitysequence
    What if one wants to apply a functon i.e. to each row of a matrix, but also wants to use as an argument for this function the number of that row. As an example, suppose you wanted to get the n-th root of the numbers in each row of a matrix, where n is the row number. Is there another way (using apply only) than column-binding the row numbers to the initial matrix, like this? test <- data.frame(x=c(26,21,20),y=c(34,29,28)) t(apply(cbind(as.numeric(rownames(test)),test),1,function(x) x[2:3]^(1/x[1]))) P.S. Actually if test was really a matrix : test <- matrix(c(26,21,20,34,29,28),nrow=3) , rownames(test) doesn't help :( Thank you.

  • MySQL COUNT() multiple columns

    - by liam
    Hello, I'm trying to fetch the most popular tags from all videos in my database (ignoring blank tags). I also need the 'flv' for each tag. I have this working as I want if each video has one tag: SELECT tag_1, flv, COUNT(tag_1) AS tagcount FROM videos WHERE NOT tag_1='' GROUP BY tag_1 ORDER BY tagcount DESC LIMIT 0, 10 However in my database, each video is allowed three tags - tag_1, tag_2 and tag_3. Is there a way to get the most popular tags reading from multiple columns? The record structure is: +-----------------+--------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +-----------------+--------------+------+-----+---------+----------------+ | id | int(11) | NO | PRI | NULL | auto_increment | | flv | varchar(150) | YES | | NULL | | | tag_1 | varchar(75) | YES | | NULL | | | tag_2 | varchar(75) | YES | | NULL | | | tag_3 | varchar(75) | YES | | NULL | | +-----------------+--------------+------+-----+---------+----------------+

  • MySQL Returns wrong values on SELECT statement

    - by Andrew K
    All, I'm wondering if this is a MySQL bug, but since I've seen others playing with larger numbers than this, I'm thinking I'm doing something wrong here.

    Here is what I have now: ListAdapter buildPhonesAdapter(Activity a) { String[] PROJECTION=new String[] { Contacts._ID, Contacts.DISPLAY_NAME, Phone.NUMBER, Email.DATA }; Cursor c=a.managedQuery(Phone.CONTENT_URI, PROJECTION, null, null, null); return(new SimpleCursorAdapter( a, android.R.layout.simple_list_item_2, c, new String[] { Contacts.DISPLAY_NAME, Phone.NUMBER, Email.DATA }, new int[] { android.R.id.text1, android.R.id.text2 })); } ListAdapter buildEmailAdapter(Activity a) { String[] PROJECTION=new String[] { Contacts._ID, Contacts.DISPLAY_NAME, Email.DATA }; Cursor c=a.managedQuery(Email.CONTENT_URI, PROJECTION, null, null, null); return(new SimpleCursorAdapter( a, android.R.layout.simple_list_item_2, c, new String[] { Contacts.DISPLAY_NAME, Email.DATA }, new int[] { android.R.id.text1, android.R.id.text2 })); } Need the 2 variables to show when cursor is picking this new option - I need Email.CONTENT_URI, and Phone.CONTENT_URI, to show when picked - I can get each one to show but need them both to show at same time.

  • Pivot to obtain EAV data

    - by Snowy
    I have an EAV table (simple key/value in every row) and I need to take the 'value' from two of the rows and concat them into a single row with a single column. I can't seem to get through the part where I just have the pivot straight. Can anyone help me figure this out? Declare @eavHelp Table ( [Key] VARCHAR (8) NOT NULL, [Value] VARCHAR (8) NULL ) Insert Into @eavHelp Values ( 'key1' , 'aaa' ) Insert Into @eavHelp Values ( 'key2' , 'bbb' ) Select * From @eavHelp Pivot ( Min( [Value] ) For [Value] in ( hmm1 , hmm2 ) ) as Piv Where [Key] = 'key1' or [Key] = 'key2' That makes: Key hmm1 hmm2 -------- -------- -------- key1 NULL NULL key2 NULL NULL But what I want to make is: hmmmX ----- aaa;bbb

  • how could it works if function is called before it is defined in python?

    - by user2131316
    I was wondering what does if __name__ == "__main__": really do in python, I have the following code in python3: def main(): test(); def test(): print("hello world " + __name__); if __name__ == "__main__": main(); we know that we have to declare a function before we use it, so function call inside of if part works fine, the main() is defined before it is called inside of if statement, but what about the test() function, it is defined after it is called and there is no errors: def main(): test(); def test(): print("hello world " + __name__); so how could it works if the test() function is defined after it is called?

  • Select rows where column LIKE dictionary word

    - by Gerve
    I have 2 tables: Dictionary - Contains roughly 36,000 words CREATE TABLE IF NOT EXISTS `dictionary` ( `word` varchar(255) NOT NULL, PRIMARY KEY (`word`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1; Datas - Contains roughly 100,000 rows CREATE TABLE IF NOT EXISTS `datas` ( `ID` int(11) NOT NULL AUTO_INCREMENT, `hash` varchar(32) NOT NULL, `data` varchar(255) NOT NULL, `length` int(11) NOT NULL, `time` int(11) NOT NULL, PRIMARY KEY (`ID`), UNIQUE KEY `hash` (`hash`), KEY `data` (`data`), KEY `length` (`length`), KEY `time` (`time`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=105316 ; I would like to somehow select all the rows from datas where the column data contains 1 or more words. I understand this is a big ask, it would need to match all of these rows together in every combination possible, so it needs the best optimization. I have tried the below query, but it just hangs for ages: SELECT `datas`.*, `dictionary`.`word` FROM `datas`, `dictionary` WHERE `datas`.`data` LIKE CONCAT('%', `dictionary`.`word`, '%') AND LENGTH(`dictionary`.`word`) > 3 ORDER BY `length` ASC LIMIT 15 I have also tried something similar to the above with a left join, and on clause that specified the like statement.
