• Is there a way to force JUnit to fail on ANY unchecked exception, even if swallowed

  - by Uri

  I am using JUnit to write some higher level tests for legacy code that does not have unit tests. Much of this code "swallows" a variety of unchecked exceptions like NullPointerExceptions (e.g., by just printing stack trace and returning null). Therefore the unit test can pass even through there is a cascade of disasters at various points in the lower level code. Is there any way to have a test fail on the first unchecked exception even if they are swallowed? The only alternative I can think of is to write a custom JUnit wrapper that redirects System.err and then analyzes the output for exceptions.

• IE incompatibility with JavaScript (surprised?)

  - by Midevil Chaos

  I am coding my website, and a friend of mine was helping me. This code does not work on IE 10 (Windows 7). I even tried the legacy modes and to no avail. Upon clicking on "services" for example, this code would work on FF or Chrome. But, not on IE. Can someone help me fix this code so it would also work on IE? $('#services-fr-2').on('click',function(){ $( ".clientsFr" ).hide(); $('.servicesFr').fadeToggle(); $('#green-pouch-fr').animate({ 'top':'450px'//, //'height':'450' })

• jQuery cookie behaves differently on local machine vs production server

  - by user1810414

  I'm setting a jQuery cookie for some site javascript effects. I'm setting expiration date to 30 days. On local development machine cookie expiration is set properly, whereas on production expiration is being set to end of session. After inspecting the created cookies with web develoer tools, everything is identical except production machine cookie is marked as "session cookie" and setting expiration is disallowed, while cookie created on local development machine is not set to "session" and expiration date is editable. Is there a way to make production machine cookie accept the expiration date? This is how I set the cookie: $.cookie('skip_animation','skip', 2592000); Using jQuery 1.6.4 (legacy site) All browsers behave the same way

• How to order my objects in a C++ class correctly

  - by Julen

  Hello, I have been coding regurlarly in C++ in the past months. I am getting used to it step by step... but there are things that confuse me about formatting. I know there is a lot of legacy from C that I supousee mixes with C++. This time I have doubts about how to order properly my members and functions within in a class. Also considering their access modifiers. How is the convention in this? Until know I am doing everything "public" and writing first constructor of class, then destructor, next members and finally functions. It this correct? What happens when introducing "private" and "protected" access modifiers or "virtual" functions? From the documents I have look in the Internet there is different ways of doing things. But my questions aims to get the knowledge from a community that develops in C++ that I want to blend into. ;-) Thanks a lot!!!

• ASP SaveToDisk method takes an incredible amount of time

  - by burnt_hand

  This is a method in ASP Classic that saves a file to disk. It takes a very long time but I'm not sure why. Normally, I wouldn't mind so much, but the files it handles are pretty large so need this needs to faster than 100kB a second save. Seriously slow. (old legacy system, band aid fix till it gets replaced...) Public Sub SaveToDisk(sPath) Dim oFS, oFile Dim nIndex If sPath = "" Or FileName = "" Then Exit Sub If Mid(sPath, Len(sPath)) <> "\" Then sPath = sPath & "\" '" Set oFS = Server.CreateObject("Scripting.FileSystemObject") If Not oFS.FolderExists(sPath) Then Exit Sub Set oFile = oFS.CreateTextFile(sPath & FileName, True) For nIndex = 1 to LenB(FileData) oFile.Write Chr(AscB(MidB(FileData,nIndex,1))) Next oFile.Close End Sub I'm asking because there are plenty of WTF's in this code so I'm fighting those fires while getting some help on these ones.

• Mysql: how do I make an exact working copy of a table?

  - by epo

  I am working on a restructuring of a legacy database and its associated applications. To keep old and new working in parallel I have created a development database and copied the tables of interest to it, e.g. create database devdb; drop table if exists devdb.tab1; CREATE TABLE devdb.tab1 like working.tab1; insert into devdb.tab1 select * from working.tab1; Having done this I notice that triggers affecting tab1 have not been copied over. Is there any way in which I can produce a working copy of tab1, i.e. data, permissions, triggers, everything?

• Preserve trailing whitespace Sybase

  - by AngryWhenHungry

  I have a big chunk of textual data which I split and write multiple rows of a varchar(255) column of a table. Sometimes, the last character happens to be a space. When I read back this row, the trailing space is chopped and I get only 254 characters. This messes up my data when I append the next row to the end of this one. My code sends the full 255 char (incl space) to the DB API. How can I check that the trailing space is actually written to the table? I am not in a position to rewrite/redesign legacy code. Is there any setting - either in the DB, DB interface, read/write calls etc - that I can use to preserve the trailing space?

• Converting a company from SVN to Hg?

  - by Michael

  We're a heavy user of SVN here. While the advantages of GIT over SVN made us want to change, the advantages of Hg over SVN mean it's now time to change and we need to start doing so very soon. I'm not so worried on the client side, but here are my questions. There are some excellent books on setting file metaproperties, properly organizing projects, etc on SVN. What is that book(s) for Hg? Is there a way to convert an SVN repository (that you've used) and can report how well it went? We don't want to lose years of commit logs if possible. When you DO convert, how did you split up the old code? Did you commit trunk as one project, and tags/forks as another? If you used SVN for legacy work, did you check in updates to SVN or something else?

• Sharepoint 2010 - Managed KeyWords

  - by Audioillity

  Hi, Is it possible to import managed keywords into SharePoint 2010? Where are the keywords stored within which database? Background - I'm currently working on a migration from a legacy system into SharePoint 2010. So far everything is going well, and I can even bring across the managed meta data across along with most other data. The process I use was built for SharePoint 2007 to update Lists over SOAP. With a few manual tweaks I've managed to get the metadata to come across. To bring across either managed metadata or managed keywords I need to know the ID for the existing label/keyword. I have this for the Managed Metadata however not for the Managed Keyword. Currently I create a CSV file to be imported for managed metadata before working out the reverent GUID for the source label. Many Thanks Luke

• SQL Server column level security

  - by user46372

  I think I need some pointers on security in SQL Server. I'm trying to restrict some of our end users from getting access to certain columns (i.e. SSN) on a table. I thought I could just use column level security to restrict access to the columns. That successfully prevented users from accessing the table directly, but I was surprised that they could still get to those columns through a view that accessed that table. I followed the tips here: http://www.mssqltips.com/sqlservertip/2124/filtering-sql-server-columns-using-column-level-permissions/ Those were very helpful, but when I created a view at the end, the intern was able to access that column by default I've read that views are the best way to accomplish this, but I really don't want to go through and change all of the views and the legacy front-end application. I would rather just restrict it once on the table and if a view tries to access that column it would just fail. Is that possible or am I misunderstanding how security works in SQL Server?

• How to get notified of modification in the memory in Linux

  - by Song Yuan

  In a userspace program in Linux, I get a piece of memory via allocation from the heap, then the pointer is distributed to a lot of other components running in other threads to use. I would like to get notified when the said piece of memory is modified. I can of course develop a custom userspace solution for other components to use when they try to modify the memory. The problem in my case is that these are legacy components and they can write to memory in many occasions. So I'm wondering whether there is a similar API like inotify (get notified when file is changed) or other approaches in order to get notified when a piece of memory is changed. I considered using mmap and inotify, which obviously won't work if the changes are not flushed. Any suggestions are appreciated :-)

• Does iBatis enforce a primary key on my table?

  - by Yousui

  Hi guys, I'm working on a legacy project. The database is poorly designed. I want to change the DB layer now. The first think go through my mind is hibernate, but I hibernate need a primary key on my table. In fact some of my table does not have primary key. So I did a google search and I find iBatis, it's sounds very good with it. But I don't know whether iBatis enforce a primary key on my table? Thanks.

• Distributed version control for HUGE projects - is it feasible?

  - by Vilx-

  We're pretty happy with SVN right now, but Joel's tutorial intrigued me. So I was wondering - would it be feasible in our situation too? The thing is - our SVN repository is HUGE. The software itself has a 15 years old legacy and has survived several different source control systems already. There are over 68,000 revisions (changesets), the source itself takes up over 100MB and I cant even begin to guess how many GB the whole repository consumes. The problem then is simple - a clone of the whole repository would probably take ages to make, and would consume far more space on the drive that is remotely sane. And since the very point of distributed version control is to have a as many repositories as needed, I'm starting to get doubts. How does Mercurial (or any other distributed version control) deal with this? Or are they unusable for such huge projects?

• When is it good to use FTP?

  - by Tom Duckering

  In my experience I see a lot of architecture diagrams which make extensive use of FTP as a medium for linking architectural components. As someone who doesn't make architectural decisions but tends to look at architecture diagrams could anyone explain what the value is of using FTP, where it's appropriate and when transferring data as files is a good idea. I get that there are often legacy systems that just need to work that way - although any historical insight would be interesting too I can see the attraction in transferring files (especially if that's what needs to be transferred) because of the simplicity and familiarity and wonder if the reasoning goes beyond this.

• Efficient mapping for a particular finite integer set

  - by R..

  I'm looking for a small, fast (in both directions) bijective mapping between the following list of integers and a subset of the range 0-127: 0x200C, 0x200D, 0x200E, 0x200F, 0x2013, 0x2014, 0x2015, 0x2017, 0x2018, 0x2019, 0x201A, 0x201C, 0x201D, 0x201E, 0x2020, 0x2021, 0x2022, 0x2026, 0x2030, 0x2039, 0x203A, 0x20AA, 0x20AB, 0x20AC, 0x20AF, 0x2116, 0x2122 One obvious solution is: y = x>>2 & 0x40 | x & 0x3f; x = 0x2000 | y<<2 & 0x100 | y & 0x3f; Edit: I was missing some of the values, particularly 0x20Ax, which don't work with the above. Another obvious solution is a lookup table, but without making it unnecessarily large, a lookup table would require some bit rearrangement anyway and I suspect the whole task can be better accomplished with simple bit rearrangement. For the curious, those magic numbers are the only "large" Unicode codepoints that appear in legacy ISO-8859 and Windows codepages.

  - by KSH

  Hi all, We are planning to move few of our VC++ Legacy products to C# with .NET platform.. I am in the process of collecting the relavent information before making the proposal to give optimistic and effective approach to clients. Am looking for the following details. Any general guidelines in migration of VC++ to C#.NET What are the issues that a team can face when we take up this activity Are there any existing approaches available ? I believe many might have tried but may not have detailed information, but consolidating this under this would help not only me but anyone who look for these information. Any good / valid resources available on internet? Any suggestions from Microsoft team if any Microsoft people in this group? Architecture, components design approaches, etc. Please help me in getting these information, each penny would help me to gain good understanding.. Thanks in advance to those who will share their wisdom thorough this query.

• How can i see how many mysql connections are opend ?

  - by Sahal

  How can i see how many number of connections are opened in one request. (mysql_connect) I know that if i call mysql_connect function 100 times, function will return the connection link which is already opened only if parameters of the function is same. It will not request for new connection if connection is already exists. But i just want to make sure mysql_connect is not requesting new. I am working with a legacy system which contains so many "mysql_connect" function. Is there any setting in apache or is there any way i can log this number of connection value in apache or mysql log file? Please help.

• Writing a C++ wrapper for a C library

  - by stripes

  I have a legacy C library, written in an OO type form. Typical functions are like: LIB *lib_new(); void lib_free(LIB *lib); int lib_add_option(LIB *lib, int flags); void lib_change_name(LIB *lib, char *name); I'd like to use this library in my C++ program, so I'm thinking a C++ wrapper is required. The above would all seem to map to something like: class LIB { public: LIB(); ~LIB(); int add_option(int flags); void change_name(char *name); ... }; I've never written a C++ wrapper round C before, and can't find much advice about it. Is this a good/typical/sensible approach to creating a C++/C wrapper?

• Is object clearing/array deallocation really necessary in VB6/VBA (Pros/Cons?)

  - by Oorang

  Hello, A lot of what I have learned about VB I learned from using Static Code Analysis (Particularly Aivosto's Project Analyzer). And one one of things it checks for is whether or not you cleared all objects and arrays. I used to just do this blindly because PA said so. But now that I know a little bit more about the way VB releases resources, it seems to me that these things should be happening automatically. Is this a legacy feature from pre VB6, or is there a reason why you should explicitly set objects back to nothing and use Erase on arrays?

• How do I return an object that is able to execute on the server?

  - by mafutrct

  Coming from a Java background, this is the way I'm thinking: The server provides an object to the client. This object should be able to execute on the server. Server: private string _S = "A"; public interface IFoo { void Bar(); } private class Foo : IFoo { void Bar() { _S = "B";} } public IFoo GetFoo() { return new Foo(); } Client: IFoo foo = serverChannel.GetFoo(); foo.Bar(); Remoting is legacy (everyone keeps pointing to WCF instead) and WCF does not support this at all basically ( http://stackoverflow.com/questions/2431510 ), so how should I implement this kind of behavior? Using 3rd party components is possible iff required. I searched on SO but found no similar question. If this has indeed been answered before, just let me know and I'll delete.

• All of a Sudden , Sql Server Timeout

  - by Adinochestva

  Hey Guys We got a legacy vb.net applicaction that was working for years But all of a sudden it stops working yesterday and gives sql server timeout Most part of application gives time out error , one part for example is below code : command2 = New SqlCommand("select * from Acc order by AccDate,AccNo,AccSeq", SBSConnection2) reader2 = command2.ExecuteReader() If reader2.HasRows() Then While reader2.Read() If IndiAccNo <> reader2("AccNo") Then CAccNo = CAccNo + 1 CAccSeq = 10001 IndiAccNo = reader2("AccNo") Else CAccSeq = CAccSeq + 1 End If command3 = New SqlCommand("update Acc Set AccNo=@NewAccNo,AccSeq=@NewAccSeq where AccNo=@AccNo and AccSeq=@AccSeq", SBSConnection3) command3.Parameters.Add("@AccNo", SqlDbType.Int).Value = reader2("AccNo") command3.Parameters.Add("@AccSeq", SqlDbType.Int).Value = reader2("AccSeq") command3.Parameters.Add("@NewAccNo", SqlDbType.Int).Value = CAccNo command3.Parameters.Add("@NewAccSeq", SqlDbType.Int).Value = CAccSeq command3.ExecuteNonQuery() End While End If It was working and now gives time out in command3.ExecuteNonQuery() Any ideas ?

• C++ - Implementing my own stream

  - by HardCoder1986

  Hello! My problem can be described the following way: I have some data which actually is an array and could be represented as char* data with some size I also have some legacy code (function) that takes some abstract std::istream object as a param and uses that stream to retrieve data to operate. So, my question is the following - what would be the easy way to map my data to some std::istream object so that I can pass it to my function? I thought about creating a std::stringstream object from my data, but that means copying and (as I assume) isn't the best solution. Any ideas how this could be done so that my std::istream operates on the data directly? Thank you.

• Pointer aliasing- in C++0x

  - by DeadMG

  I'm thinking about (just as an idea) disjointed pointer aliasing in C++0x. I was thinking about seeing if it could be implemented similarly to const correctness- that is, enforced by the compiler. What would be the requirements for such a thing? As this is more of a thought experiment, I'm perfectly happy to look at solutions that destroy legacy code or redefine half the language and that kind of thing. What I'd really rather not do is have, say, restrict from C99 where the programmer just promises it. It should be enforced.

• Periods in Javascript function definition (function window.onload(){}) [closed]

  - by nemec

  Possible Duplicate: JavaScript Function Syntax Explanation: function object.myFunction(){..} I've seen some (legacy) javascript code recently that looks like: function window.onload(){ // some code } This doesn't look like valid javascript to me since you can't have a period in an identifier, but it seems to work in IE8. I assume it's the equivalent of: window.onload = function(){} I've tried the same code in Chrome and IE9 and both of them raise syntax exceptions, so am I correct in thinking that this "feature" of IE8 is some non-standard function definition that should be replaced? The code in question is only sent to IE browsers, so that's probably why I haven't run into this issue before.

• warning: '0' flag ignored with precision and ‘%i’ gnu_printf format

  I am getting the following warning when compiling some legacy C code on Ubuntu Karmic, using gcc 4.4.1 The warning is: src/filename.c:385: warning: '0' flag ignored with precision and ‘%i’ gnu_printf format The snippet which causes the warning to be emitted is: char buffer[256] ; long fnum ; /* some initialization code here ... */ sprintf(buffer, "F%03.3i.DTA", (int)fnum); /* <- warning emitted here */ I think I understand the warning, but I would like to check in here to see if I am right, and also the (definite) correct way of resolving this.
