Dovecot unable to perform mysql query

- by NathanJ2012

I have been following the ISPMail tutorials on workaround.org (the 2.9 Wheezy version) and thus far everything has been working fine. When I reached the step to "Testing email delivery" step I noticed a error about the query in the output log from /var/log/mail.log. May 14 06:48:59 mail postfix/pickup[17704]: EA4AD240A98: uid=0 from=<root> May 14 06:48:59 mail postfix/cleanup[17776]: EA4AD240A98: message-id=<[email protected]> May 14 06:48:59 mail postfix/qmgr[17706]: EA4AD240A98: from=<[email protected]>, size=429, nrcpt=1 (queue active) May 14 06:49:00 mail dovecot: auth-worker(17782): mysql(127.0.0.1): Connected to database mailserver May 14 06:49:00 mail dovecot: auth-worker(17782): Warning: mysql: Query failed, retrying: Table 'mailserver.users' doesn't exist May 14 06:49:00 mail dovecot: auth-worker(17782): Error: sql([email protected]): User query failed: Table 'mailserver.users' doesn't exist (using built-in default user_query: SELECT home, uid, gid FROM users WHERE username = '%n' AND domain = '%d') May 14 06:49:00 mail dovecot: lda([email protected]): msgid=<[email protected]>: saved mail to INBOX May 14 06:49:00 mail postfix/pipe[17780]: EA4AD240A98: to=<[email protected]>, relay=dovecot, delay=0.09, delays=0.03/0.01/0/0.06, dsn=2.0.0, status=sent (delivered via dovecot service) May 14 06:49:00 mail postfix/qmgr[17706]: EA4AD240A98: removed I found this rather interesting that it isn't finding the DB so I went back through and checked EVERY file that I touched that involved the DB (including the postfix cf files) and everything is correct so I am baffled at this point, but oddly enough it would seem the email still made it to the correct destination in /var/vmail/domain.com/. Should I be worried about this or am I missing something here?

How to move your Windows User Profile to another drive in Windows 8

- by Mark

I like to have my user folder on a different drive (D:) than my OS is (C:). Reading the following post I decided to give it a try. All went quite well, untill I found out that my Windows 8 Apps won't execute anymore (other than that I didn't noticed any problems). My apps do work, while using an account that isn't moved. In the eventviewer I've found error messages like these: App <Microsoft.MicrosoftSkyDrive> crashed with an unhandled Javascript exception. App details are as follows: Display Name:<SkyDrive>, AppUserModelId: <microsoft.microsoftskydrive_8wekyb3d8bbwe!Microsoft.MicrosoftSkyDrive> Package Identity:<microsoft.microsoftskydrive_16.4.4204.712_x64__8wekyb3d8bbwe> PID:<4452>.

I noticed that the app folders e.g.: D:\Users\john\AppData\Local\Packages\microsoft.microsoftskydrive_8wekyb3d8bbwe had a different owner than the old profile folder had. Old profile folder had john as owner where my new profile folder had the Administrators group as owner. Changing this didn't help unfortunately.

Problem converting a byte array into datatable.

- by kranthi

Hi, In my aspx page I have a HTML inputfile type which allows user to browse for a spreadsheet.Once the user choses the file to upload I want to read the content of the spreadsheet and store the content into mysql database table. I am using the following code to read the content of the uploaded file and convert it into a datatable in order into insert it into database table. if (filMyFile.PostedFile != null) { // Get a reference to PostedFile object HttpPostedFile myFile = filMyFile.PostedFile; // Get size of uploaded file int nFileLen = myFile.ContentLength; // make sure the size of the file is > 0 if (nFileLen > 0) { // Allocate a buffer for reading of the file byte[] myData = new byte[nFileLen]; // Read uploaded file from the Stream myFile.InputStream.Read(myData, 0, nFileLen); DataTable dt = new DataTable(); MemoryStream st = new MemoryStream(myData); st.Position = 0; System.Runtime.Serialization.IFormatter formatter = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter(); dt=(DataTable)formatter.Deserialize(st); } } But I am getting the following error when I am trying to deserialise the byte array into datatable. Binary stream '0' does not contain a valid BinaryHeader. Possible causes are invalid stream or object version change between serialization and deserialization. Could someone please tell me what am I doing wrong? I've also tried converting the bytearray into string ,then converting the string back to byte array and convert into datatable.That is also throwing the same error. Thanks.

JSON and Microformats

- by Tauren

I'm looking for opinions on whether microformats should be used to name JSON elements. For instance, there is a microformat for physical addresses, that looks like this: <div class="adr"> <div class="street-address">665 3rd St.</div> <div class="extended-address">Suite 207</div> <span class="locality">San Francisco</span>, <span class="region">CA</span> <span class="postal-code">94107</span> <div class="country-name">U.S.A.</div> </div> There is a document available on using JSON and Microformats. The information above could be represented as JSON data like this: "adr": { "street-address":"665 3rd St.", "extended-address":"Suite 207", "locality":"San Fransicso", "region":"CA", "postal-code":"94107", "country-name":"U.S.A." }, The issue I have with this is that I'd like my JSON data to be as lightweight as possible, but still human readable. While still supporting international addresses, I would prefer something like this: "address": { "street":"665 3rd St.", "extended":"Suite 207", "locality":"San Fransicso", "region":"CA", "code":"94107", "country":"U.S.A." }, If I'm designing a new JSON API right now, does it make sense to use microformats from the start? Or should I not really worry about it? Is there some other standard that is more specific to JSON that I should look at?

Copy data from different worksheet to a master worksheet but no duplicates

- by sam

hi all, i want to clarify my initial question for a possible solutions from any savior out there. Say i have 3 excel sheets one for each user for data entry located in separate workbooks to avoid excel share workbook problems. I also have a master sheet in another workbook where i want individual data enter on those sheets precisely sheets 1 should copy to the next available row of sheet 1 in the master sheet as the users enter them. i need a vba code that can copy each record without copying a duplicate row in the master sheet but highlight the duplicate row and lookup the initial record in a master sheet and return the name of the Imputer looking up the row say column ( I) where each user sign there initials after every row of entry like below. All 4 worksheets are formatted as below: lastname account cardno. type tran amount date location comments initials JAME 65478923 1975 cash 500 4/10/2010 miles st. this acct is resolve MLK BEN 52436745 1880 CHECK 400 4/12/2010 CAREY ST Ongoing investigation MLK JAME 65478923 1975 cash 500 4/10/2010 miles st. this acct is resolve MLK I need the vba to recognize duplicates only if the account number and the card number matches the initial records. So if the duplicates exist a pop up message should be display that a duplicates exist and return the initial Imputer say MLK in COLUMN( I) to any user inputting in the individual worksheets other than warehouse sheets (master). So please any idea will be appreciated.

Using RecordStore in Java J2ME

- by me123

Hi, I am currently doing some J2ME development. I am having a problem in that a user can add and remove elements to the record store, and if a record gets deleted, then that record is left empty and the others don't move up one. I'm trying to come up with a loop that will check if a record has anything in it (incase it has been deleted) and if it does then I want to add the contents of that record to a list. My code is similar to as follows: for (int i = 1; i <= rs.getNumRecords(); i++) { // Re-allocate if necessary if (rs.getRecordSize(i) > recData.length) recData = new byte[rs.getRecordSize(i)]; len = rs.getRecord(i, recData, 0); st = new String(recData, 0, len); System.out.println("Record #" + i + ": " + new String(recData, 0, len)); System.out.println("------------------------------"); if(st != null) { list.insert(i-1, st, null); } } When it gets to rs.getRecordSize(i), I always get a "javax.microedition.rms.InvalidRecordIDException: error finding record". I know this is due to the record being empty but I can't think of a way to get around this problem. Any help would be much appreciated. Thanks in advance.

Problem storing a hash in DB using Storable::nfreeze in Perl

- by Sam

I want to insert a hash in the db using Storable::nfreeze but the data is not inserted properly. My code is as follows: %rec=(); $rec{'name'} = 'my name'; $rec{'address'} = 'my address'; my $order1 = new Order(); $order1->set_session(\%rec); $self->createOrder($order1); sub createOrder { my $self = $_[0]; my $order = $_[1]; # Retrieve the fields to insert into the database. my $st = $dbh->prepare("insert into order (session,.......) values(?,........)"); my $session = %{$order->get_session()}; $st->execute(&Storable::nfreeze(\%session),.....); $st->finish(); } sub getOrder { ... my $session = &Storable::thaw( $ref->{'session'} ); ..... } The thaw is working fine because I tested it withe some rows that have been inserted correctly, but when I try to get a row that was inserted using the createOrder subroutine, I get an error saying: Storable binary image v36.65 more recent than I am (v2.7) at blib/lib/Storable.pm (autosplit into blib/lib/auto/Storable/thaw.al) line 415 The error comes from the line that have thaw. The nfreeze did not store the hash properly. Can someone point me to what I'm doing wrong in the createOrder subroutine? I know the module version have nothing to do with the problem.

Is it possible to group records belonging to an entity in dbunit?

- by Joshua

Our JPA entity model auto-generates primary key identifiers for user, user_address tables. Would it be possible to group these entities given below via dbunit, so that I don't need to provide neither the primary key as well as the foreign key reference from user_address.user_id. It is getting very hard to maintain these keys (i.e. I would prefer to group the primary record 'user' and the child records 'user_address' so that dbunit can group them automatically by looking up the entity metadata). Is it achievable? <user id="1" first_name="Josh" creation_date="2009-07-11 15:45:28"/> <user_address id="1" user_id="1" address="Main St" city="Los Angeles"/> I would prefer something like this  <user first_name="Josh" creation_date="2009-07-11 15:45:28"/> <user_address address="Main St" city="Los Angeles"/>  <user first_name="Mary" creation_date="2009-07-11 15:45:28"/> <user_address address="Taylors St" city="San Jose"/>

One or more rows contain values violating non-null, unique, or foreign-key constraints in SQL Script

- by Musikero31

Need help on this. I'm just wondering why this error occurred. Below is the script concerned. SELECT loc.ID ,loc.LocCode ,loc.LocName ,st.StateName ,reg.RegionName ,ctry.CountryName ,ISNULL(CONVERT(DATE, loc.UpdatedDate), CONVERT(DATE,loc.CreatedDate)) AS [ModifiedDate] ,stf.Name AS [ModifiedBy] FROM Spkr_Country AS ctry WITH (NOLOCK) INNER JOIN Spkr_Location AS loc WITH (NOLOCK) ON ctry.ID = loc.CountryID INNER JOIN Spkr_State AS st WITH (NOLOCK) ON loc.StateID = st.ID INNER JOIN Spkr_Region AS reg WITH (NOLOCK) ON loc.RegionID = reg.ID INNER JOIN Staff AS stf ON ISNULL(loc.UpdatedBy, loc.CreatedBy) = stf.StaffId WHERE (loc.IsActive = 1) AND ( (@LocCode = '') OR ( @LocCode <> '' AND loc.LocCode LIKE @LocCode + '%' ) ) AND ( (@RegionID < 1) OR ( @RegionID > 0 AND loc.RegionID = @RegionID ) ) AND ( (@StateID < 1) OR ( @StateID > 0 AND loc.StateID = @StateID ) ) AND ( (@CountryID < 1) OR ( @CountryID > 0 AND loc.CountryID = @CountryID ) ) The error probably occurred here INNER JOIN Staff AS stf ON ISNULL(loc.UpdatedBy, loc.CreatedBy) = stf.StaffId The requirement that I wanted is that if the loc.UpdatedBy is null, it will use the loc.CreatedBy column. However, when I used this, it generated the error mentioned. In the database, the loc.CreatedBy is not null while the loc.UpdatedBy is nullable. I checked it by running the script but it's working fine. How do I do with it? What's wrong with my code? Please help.

java url connection, wait for data being sent through the outputstream

- by Mateu

I'm writting a java class that tests uploading speed connection to a server. I want to check how many data can be send in 5 seconds. I've written a class which creates a URL, creates a connection, and sends data trough the outPutStream. There is a loop where I writte data to the stream for 5 seconds. However I'm not able to see when data has been send (I writte data to the output stream, but data is not send yet). How can I wait untill data is really sent to the server? Here goes my code (which does not work): URL u = new URL(url) HttpURLConnection uc = (HttpURLConnection) u.openConnection(); uc.setDoOutput(true); uc.setDoInput(true); uc.setUseCaches(false); uc.setDefaultUseCaches(false); uc.setRequestMethod("POST"); uc.setRequestProperty("Content-Type", "application/octet-stream"); uc.connect(); st.start(); // Send the request OutputStream os = uc.getOutputStream(); //This while is incorrect cause it does not wait for data beeing sent while (st.getElapsedTime() < miliSeconds) { os.write(buffer); os.flush(); st.addSize(buffer.length); } os.close(); Thanks

I have the next methods in my singleton to execute the JDBC connections public void openDB() throws ClassNotFoundException, IllegalAccessException, InstantiationException, SQLException { Class.forName("com.mysql.jdbc.Driver").newInstance(); String url = "jdbc:mysql://localhost/mbpe_peru";//mydb conn = DriverManager.getConnection(url, "root", "admin"); st = conn.createStatement(); } public void sendQuery(String query) throws SQLException { st.executeUpdate(query); } public void closeDB() throws SQLException { st.close(); conn.close(); } And I'm having a problem in a void where i have to call this twice. private void jButton1ActionPerformed(ActionEvent evt) { Main.getInstance().openDB(); Main.getInstance().sendQuery("call insertEntry('"+EntryID()+"','"+SupplierID()+"');"); Main.getInstance().closeDB(); Main.getInstance().openDB(); for(int i=0;i<dataBox.length;i++){ Main.getInstance().sendQuery("call insertCount('"+EntryID()+"','"+SupplierID()+"','"+BoxID()+"'); Main.getInstance().closeDB(); } } I have already tried to keep the connection open and send the 2 querys and after that closed and it didnt work... The only way it worked was to not use the methods, declare the commands for the connection and use different variables for the connection and the statement. I thought that if i close the Connecion and the Statement I could use the variable once again since is a method but I'm not able to. Is there any way to solve this using my methods for the JDBC connection?

Java: I've created a list of word objects to include the name and the frequency, but having trouble

- by adam08

Hi Everyone, I'm working on a project which has a dictionary of words and I'm extracting them and adding them to an ArrayList as word objects. I have a class called Word as below. What I'm wondering is how do I access these word objects to update the frequency? As part of this project, I need to only have one unique word, and increase the frequency of that word by the number of occurrences in the dictionary. Word(String word) { this.word = word; this.freq = 0; } public String getWord() { return word; } public int getFreq() { return freq; } public void setFreq() { freq = freq + 1; } This is how I am adding the word objects to the ArrayList...I think it's ok? String pattern = "[^a-zA-Z\\s]"; String strippedString = line.replaceAll(pattern, ""); line = strippedString.toLowerCase(); StringTokenizer st = new StringTokenizer(line); while (st.hasMoreTokens()) { String newWord = st.nextToken(); word.add(new Word(newWord)); count++; }

Translate an IQueryable instance to LINQ syntax in a string

- by James Dunne

I would like to find out if anyone has existing work surrounding formatting an IQueryable instance back into a LINQ C# syntax inside a string. It'd be a nice-to-have feature for an internal LINQ-to-SQL auditing framework I'm building. Once my framework gets the IQueryable instance from a data repository method, I'd like to output something like: This LINQ query: from ce in db.EiClassEnrollment join c in db.EiCourse on ce.CourseID equals c.CourseID join cl in db.EiClass on ce.ClassID equals cl.ClassID join t in db.EiTerm on ce.TermID equals t.TermID join st in db.EiStaff on cl.Instructor equals st.StaffID where (ce.StudentID == studentID) && (ce.TermID == termID) && (cl.Campus == campusID) select new { ce, cl, t, c, st }; Generates the following LINQ-to-SQL query: DECLARE @p0 int; DECLARE @p1 int; DECLARE @p2 int; SET @p0 = 777; SET @p1 = 778; SET @p2 = 779; SELECT [t0].[ClassEnrollmentID], ..., [t4].[Name] FROM [dbo].[ei_ClassEnrollment] AS [t0] INNER JOIN [dbo].[ei_Course] AS [t1] ON [t0].[CourseID] = [t1].[CourseID] INNER JOIN [dbo].[ei_Class] AS [t2] ON [t0].[ClassID] = [t2].[ClassID] INNER JOIN [dbo].[ei_Term] AS [t3] ON [t0].[TermID] = [t3].[TermID] INNER JOIN [dbo].[ei_Staff] AS [t4] ON [t2].[Instructor] = [t4].[StaffID] WHERE ([t0].[StudentID] = @p0) AND ([t0].[TermID] = @p1) AND ([t2].[Campus] = @p2) I already have the SQL output working as you can see. I just need to find a way to get the IQueryable to translate into a string representing its original LINQ syntax (with an acceptable translation loss). I'm not afraid of writing it myself, but I'd like to see if anyone else has done this first.

struts2 invalid.token returned when form submitted using JQuery

- by John

Hi, I have inherited some code in which I now have to add CSRF prevention and am trying to use the struts2 tokenSession interceptor to do this. I am adding a token to my form using the struts2 token tag like so: <form id="updateObject" name="updateObject" action="<%=request.getContextPath()%>/prv/updateObject.action" method="POST"> <fieldset class="x-fieldset"> <legend>Update object - Action Required</legend> <div>...</div> <s:token /> <s:hidden name="id" id="objectId" /> more stuff here... <input type="submit" value="Update Object" onclick="javascript:return doUpdateObject('myAction');"/> </fieldset> </form> In my javascript function, I am adding/removing some validation rules (depending upon the action required, and submitting the form: function doUpdateObject(action){ actionPanel.registerAction(action); // this function places the action name in an in-scope variable doUpdateObjectValidationSetup(action); // this function adds/removes jquery validation rules depending upon the action if($("#updateObject").valid()){ $("form#updateObject").submit(); } return false; } I have intercepted the request and a token is being added, however the struts2 tokenSession interceptor is returning invalid.token. The code works as expected without this interceptor. (struts2 xml file not posted - will post the relevant section if required). I have also used the tokenSession interceptor in other pages which use a basic html submit button (i.e. not going via javascript or jquery) and this also works as expected. What is making the token invalid? N.B. The project I have inherited uses a strange mixture of standard html, struts2 tags, ExtJS and JQuery. I will clean this up at some point but at the moment I just need to get the tokenSession interceptor working asap in the code as-is (as I have to apply a similar fix to several hundred pages...). Any help/pointers/tips/etc greatly appreciated! Regards, John
