• Memory section handling error

  - by Basilevs

  I'm getting a link time error: WARNING: /home/gulevich/development/camac-fedorov/camac/linux/k0607-lsi6/camac-k0607-lsi6.o (.ctors): unexpected non-allocatable section. Did you forget to use "ax"/"aw" in a .S file? Note that for example <linux/init.h> contains section definitions for use in .S files. The code causing the error (assembly in C source): # if defined(__ELF__) # define __SECTION_FLAGS ", \"aw\" , @progbits" /* writable flag needed for ld ".[cd]tors" sections bug workaround) */ # elif defined(__COFF__) # define __SECTION_FLAGS ", \"dr\"" /* untested, may be writable flag needed */ # endif asm ( ".section .ctors" __SECTION_FLAGS "\n" ".globl __ctors_begin__\n" "__ctors_begin__:\n" ".previous\n" ); Is there any way to fix this? The idea is to put a varaible __ctors_begin__ at the beginning of a certain memory section. This code is a legacy that worked fine using a different build system and older compiler. Meaning of this assembly code explained in an answer to my previous question.

• .NET values lookup

  - by Maciej

  Hi, I have a feeling of missing something obvious. UDP receiver application. It holds a collection of valid UDP sender IPs - only guys with IP on that list will be considered. Since that list must be looked at on every packet and UDPs are so volatile, that operation must be maximum fast. Good choice is Dictionary but it is a key-value structure and what I actually need here is a dictionary-like (hash lookup) key only structure. Is there something like that? Small annoyance rather than a bug but still. I can still use Dictionary Thanks, M.

• Is it possible to put myBatis (iBatis) xml mappers outside the project?

  - by kospiotr

  According to the user guide i am able to use file path instead of resource: // Using classpath relative resources <mappers> <mapper resource="org/mybatis/builder/AuthorMapper.xml"/> </mappers> // Using url fully qualified paths <mappers> <mapper url="file:///var/sqlmaps/AuthorMapper.xml"/> </mappers> in my project I'm trying to put my mapper xml "outside" the project and i'm doing this: <mapper url="file://D:/Mappers/ComponentMapper1.xml" /> The output of my log4j console: Error building SqlSession.

• Why do I get CA1811 when I call a private method from a public method in C++/CLI?

  - by brickner

  I've recently upgraded my project from Visual Studio 2008 to Visual Studio 2010. By enabling Code Analysis and building on Release, I'm getting warning CA1811: Avoid uncalled private code. I've managed to reduce the code to this: .h file: public ref class Foo { public: virtual System::String^ ToString() override; private: static System::String^ Bar(); }; .cpp file: String^ Foo::ToString() { return Bar(); } String^ Foo::Bar() { return "abc"; } The warning I get: CA1811 : Microsoft.Performance : 'Foo::Bar(void)' appears to have no upstream public or protected callers. It doesn't matter if Bar() is static or not. I've tried to reproduce it in C# but I can't. I can only reproduce it in C++/CLI. Why do I get this warning? Is this a Visual Studio 2010 bug?

• REST API for driving distance?

  - by Mark

  Is there a service that will give me the driving distance between two addresses? Apparently Google Maps API requires you to display a map, which I don't want to do (on that particular page), and I'd like to just snag the data and save it to my DB after a user submits a form, rather than waiting for JS to do it's thing. If it's relevant, this is going into a Django app. I discovered that CloudMade offers a Python API, which is nice, except their latest dev release has a bug in it (can't use the API object), but more importantly, it's support for Canada is awful/worthless (couldn't find directions from any major city around here!).

• Why do I get a "Day too big" error from Perl?

  - by azp74

  I have been helping someone debug some code where the error message was "Day too big". I know that this springs from localtime and the Y2038 bug (most google results appear to be people dealing with cookies expiring well into the future). We appear to have 'fixed' the problem by using time to get the current date. However, given that none of our original dates should have hit the 2038 issue I'm sceptical that we've actually fixed the problem ... Are there other instances that anyone knows of where one would hit "day too big"? OS is Solaris. Sample code - the actual code is quite large and the person I'm working with hasn't actually isolated the offending part (which is why I'm worried the 'fix' is not actually a fix). If I can put together something concise which reproduces the issue I will post!

• Null reference exceptions in .net

  - by Carlo

  Hello, we're having this big problem with our application. It's a rather large application with several modules, and thousands and thousands lines of code. A lot of parts of the application are designed to exist only with a reference to another object, for example a Person object can never exists without a House object, so if you at any point in the app say: bool check = App.Person.House == null; check should always be false (by design), so, to keep using that example, while creating modules, testing, debugging, App.Person.House is never null, but once we shipped the application to our client, they started getting a bunch of NullReferenceException with the objects that by design, should never have a null reference. They tell us the bug, we try to reproduce it here, but 90% of the times we can't, because here it works fine. The app is being developed with C# and WPF, and by design, it only runs on Windows XP SP 3, and the .net framework v3.5, so we KNOW the user has the same operative system, service pack, and .net framework version as we do here, but they still get this weird NullReferenceExceptions that we can't reproduce. So, I'm just wondering if anyone has seen this before and how you fixed it, we have the app running here at least 8 hours a day in 5 different computers, and we never see those exceptions, this only happens to the client for some reason. ANY thought, any clue, any solution that could get us closer to fixing this problem will be greatly appreciated. Thanks!

• Why doesn't MySQL support millisecond precision?

  - by Byron Whitlock

  So I just found the most frustrating bug ever in MySQL. Apparently the TIMESTAMP field, and supporting functions do not support any greater precision than seconds!? So I am using PHP and Doctrine, and I really need those microseconds (I am using the actAs: [Timestampable] property). I found a that I can use a BIGINT field to store the values. But will doctrine add the milliseconds? I think it just assigns NOW() to the field. I am also worried the date manipulation functions (in SQL) sprinkled through the code will break. I also saw something about compiling a UDF extension. This is not an acceptable workaround because I or a future maintainer will upgrade and poof, change gone. Has anyone found a suitable workaround?

• App not shown in 2.1 Market

  - by an

  I published several free and paid app in the Market. I recently get several complains from customers about not finding my app in the 2.1 Market. Even if they have bought them before, they can't find it in the market or their download list after updating to 2.1. Can anyone tell me what the problem is? My apps only require minimal SDK 3.. Thanks a lot!! Update: It looks like that they are not shown because they have copy protection enabled. Is this a bug in the Market?

• Flex 3 / ColdFusion Session Issue?

  - by dcolumbus

  Alright so this is an odd one... I have an application built in ColdFusion with a lot of the interactivity done with Flex. When a user logs in, there are session variables, as well as the client session that is evoked. When you browse to any given Flex Application, the variables are read in a used accordingly... however, on Windows (it seems XP and maybe others) for some reason session information like USER are randomly undefined... Could this be an issue with the session timing out? Even if I force a logout and log back in, it doesn't really seem to fix the issue... mind you, I cannot duplicate the bug myself, but it constantly happens on PCs.

• Visual Studio 2010 "Not enough storage is available to process this command"

  - by Daniel Perez

  I'm fighting with VS 2010 and this error that seems to be very common in previous versions, but it looks like not everyone is having it in the latest version. I've got VS 2010 SP1 and I'm getting this error quite often. The problem is that it's not even enough to restart VS in order to make it go away, I usually have to restart my pc, and i'm losing a lot of time doing this (it's quite frequent) I've got Windows 7 32bits (can't upgrade to 64 bits, the company doesn't allow it), and I can't do things like creating another solution (please don't reply this :) ) I've used the command to make devenv.exe LARGEADDRESSAWARE, but the error keeps on happening My virtual memory size is set to automatic, and the weird thing is that VS doesn't even take 2gb of ram, so I don't know if the error is really because it's lacking memory, or if it's some bug in the program any ideas, things to try, something?

• Support both Standard mode and Quirks mode? Is that possible and necessary?

  - by tshao

  Today I was assigned a bug saying that some page elements don't work on IE8 Quirks mode at all, and I need to fix them. The point is that I believe our pages will always be rendered in Standard mode, because we specify DOCTYPE at the beginning of every page (via master page). I'd think it must be some debugging tools changed that during testing. I managed to convice QA to close it as by design, after a brief explanation to her. Now I start to think the question that whether we should have our page work on both Standard and Quirks mode. Maybe we should try to minimize the problem even if the page is not rendering in a supposed mode? Any standard or best practices on that? Thanks!

• continuous integration web service

  - by Josh Moore

  I am in a position where I could become a team leader of a team distributed over two countries. This team would be the tech. team for a start up company that we plan to bootstrap on limited funds. So I am trying to find out ways to minimize upfront expenses. Right now we are planning to use Java and will have a lot of junit tests. I am planing on using github for VCS and lighthouse for a bug tracker. In addition I want to add a continuous integration server but I do not know of any continuous integration servers that are offered as a web service. Does anybody know if there are continuous integration servers available in a software as a service model? P.S. if anybody knows were I can get these three services at one location that would be great to know to.

• mediawiki markup equivalent of WMD live-previewing editor? (not WYSIWYG)

  - by Justin Grant

  Anyone have a recommendation for an editor like the WMD editor, but using MediaWiki markup instead of Markdown? Our site is already using MediaWiki markup but we want a slicker editor without changing markup completely. Requirements include: live preview of formatted text underneath the markup you're typing a toolbar for common formatting (bold, italic, links, bullets, numbered-list, code, etc) keyboard shortcuts for each toolbar button (e.g. CTRL+B for bold) Undo/redo via keyboard shortcuts (CTRL+Z/CTRL+Y) or toolbar buttons works well in the usual set of popular browsers (including IE6!) open-source would be preferred I've found a few options at http://www.mediawiki.org/wiki/WYSIWYG_editor, but all of these seem to be WYSIWYG editors which is not exactly what I want since full-on WYSIWYG editors tend to be bug-prone and complicate working at the markup level. Instead we want a plain-text markup editor with a client-side previewer, plus some UI niceties (toolbar, undo, keyboard shortcuts) to make editing markup easier.

• PHP fastest method of reading server response

  - by Peter John

  Hi there, im having some real problems with the lag produced by using fgets to grab the server's response to some batch database calls im making. Im sending through a batch of say, 10,000 calls and ive tracked the lag down to fgets causing the hold up in the speed of my application as the response for each call needs to be grabbed. I have found this thread http://bugs.php.net/bug.php?id=32806 which explains the problem quite well, but hes reading a file, not a server response so fread could be a bit tricky as i could get part of the next line, and extra stuff which i dont want. Any help much appreciated!

• from ggplot2 to OOo workflow?

  - by Andreas

  This is not really a programming question, but I try here none the less. I once used latex for my reports. But the people I work with needs to make small edits and do not have latex skillz. Openoffice is then the way to go. But saving ggplot images with dpi 100 makes for really ugly graphs. dpi = 600 is a no go (e.g. huge legend). So what to do? I currently save (still via ggsave) to eps - which openoffice can import. But performance is not good at all. Googling I found a bug for the poor eps performance in OOo, and also talk about a non-implemented svg feature. But none helps me right now. If you work with ggplot2 and OOo - What do you do? I have been unsuccesfull with pdf conversion for some reason.

• DbMetal chokes on repeated foreign key references in SQLite - any ideas?

  - by DanM

  I've been struggling to get DbMetal to process my SQLite database. I finally isolated the problem. It won't allow a table to have two foreign key references to the same column. For example, a SQLite database with these two tables will fail: CREATE TABLE Person ( Id INTEGER PRIMARY KEY, Name TEXT NOT NULL ); CREATE TABLE Match ( Id INTEGER PRIMARY KEY, WinnerPersonId INTEGER NOT NULL REFERENCES Person(Id), LoserPersonId INTEGER NOT NULL REFERENCES Person(Id) ); I get this error: DbMetal: Sequence contains more than one matching element If I get rid of the second foreign key reference, no error occurs. So, this works: CREATE TABLE Match ( Id INTEGER PRIMARY KEY, WinnerPersonId INTEGER NOT NULL REFERENCES Person(Id), LoserPersonId INTEGER NOT NULL ); But I really need both "person" columns to reference the person table. I submitted a bug report for this, but I could use a workaround in the meantime. Any ideas?

• Facebook API returning wrong unread thread count

  - by houbysoft

  I'm trying to query the thread FQL table to get all unread messages, and also the count of unread items in the thread. This is how I query the table: SELECT thread_id,updated_time,snippet,snippet_author,unread FROM thread WHERE folder_id=0 AND unread!=0 From reading the doc to which I linked above, it seems to me that unread should include the count of unread messages in the thread. However, I just tested the above call and Facebook gives me back a value of unread=1, despite the thread in question having 4 unread items. This is how the thread looks on facebook.com (notice the (4), showing that unread should be 4): This is what the API returns to me, which is wrong (notice the "unread":1): { "data":[ { "name":"messages", "fql_result_set":[ { "thread_id":"BLAH BLAH BLAH", "updated_time":1333317140, "snippet":"BLAH BLAH BLAH", "snippet_author":BLAH, "unread":1 } ] } ] } Am I doing something wrong, or is this a bug?

• Keyboard shortcut for Jump to Definition

  - by Arne Evertsson

  I'm looking for a keyboard only shortcut for Jump to Definition. The built-in shortcut requires the mouse: Cmd + Double click. I've tried to add a regular keyboard shorcut for the Edit / Find / Jump to Defintion menu command, but, alas, it will only work when the method name is selected. I'd like to be able to position the cursor within the method name, class name, or other symbol, and hit something like Cmd+Shift+L. Does anyone know of a solution, perhaps using a script, for the problem? Update: The keyboard shortcut works sometimes and sometimes not. When I position the text cursor on a method call with no parameters and press Cmd+Shift+L it takes me to the definition. But it doesn't work for a method that takes an (id) parameter. However it works if the parameter is an int. I have submitted a bug report to Apple.

• paypal sadbox IPN

  Morning all. I am trying to test a SIMPLE php script to deal with the IPN response from paypal sandbox. <?php // read the post from PayPal system and add 'cmd' $req = 'cmd=_notify-validate'; foreach ($post as $key => $value) { $value = urlencode(stripslashes($value)); $req .= "&$key=$value"; } // post back to PayPal system to validate $header = "POST /cgi-bin/webscr HTTP/1.0\r\n"; $header .= "Content-Type: application/x-www-form-urlencoded\r\n"; $header .= "Content-Length: " . strlen($req) .

Can anyone see whats happening and how I go about fixing. Regards, Phil

• MSBuild / PowerShell: Copy SQL Server 2012 database to SQL Azure via BACPAC (for Continuous Integration)

  - by giveme5minutes

  I'm creating a continuous integration MSBuild script which copies a database in on-premise SQL Server 2012 to SQL Azure. Easy right? Methods After a fair bit of research I've come across the following methods: Use PowerShell to access the DAC library directly, then use the MSBuild PowerShell extension to wrap the script. This would require installing PowerShell 3 and working out how to make the MSBuild PowerShell extension work with it, as apparently MS moved the DAC API to a different namespace in the latest version of the library. PowerShell would give direct access to the API, but may require quite a bit of boilerplate. Use the sample DAC Framework Client Side Tools, which requires compiling them myself, as the downloads available from Codeplex only include the Hosted version. It would also require fixing them to use DAC 3.0 classes as they appear to currently use an earlier version of DAC. I could then call these tools from an <Exec Command="" /> in the MSBuild script. Less boilerplate and if I hit any bumps in the road I can just make changes to the source. Processes Using whichever method, the process could be either: Export from on-premise SQL Server 2012 to local BACPAC Upload BACPAC to blog storage Import BACPAC to SQL Azure via Hosted DAC Or: Export from on-premise SQL Server 2012 to local BACPAC Import BACPAC to SQL Azure via Client DAC Question All of the above seems to be quite a lot of effort for something that seems to be a standard feature... so before I start reinventing the wheel and documenting the results for all to see, is there something really obvious that I've missed here? Is there pre-written script that MS has released that I have not yet uncovered? There's an command in the GUI of SQL Server Management Studio 2012 that does EXACTLY what I'm trying to do (right click on local database, click "Tasks", click "Deploy Database to SQL Azure"). Surely if it's a few clicks in the GUI it must be a single command on the command line somewhere??

• Is Boost.Tuple compatible with C++0x variadic templates ?

  - by Thomas Petit

  Hi, I was playing around with variadic templates (gcc 4.5) and hit this problem : template <typename... Args> boost::tuple<Args...> my_make_tuple(Args... args) { return boost::tuple<Args...>(args...); } int main (void) { boost::tuple<int, char> t = my_make_tuple(8, 'c'); } GCC error message : sorry, unimplemented: cannot expand 'Arg ...' into a fixed-length argument list In function 'int my_make_tuple(Arg ...)' If I replace every occurrence of boost::tuple by std::tuple, it compiles fine. Is there a problem in boost tuple implementation ? Or is this a gcc bug ? I must stick with Boost.Tuple for now. Do you know any workaround ? Thanks.

• How can I display a hidden view in Interface Builder which is on a unattached monitor?

  - by Brennan

  I am using Interface Builder to work on NIBs and one of the NIBs must have a view on my external monitor which is not attached because I cannot see it on my MacBook. I have had this problem with editing iPad NIBs which I work on with my larger external monitor. For some reason Interface Builder is not detecting that there is now just one screen and not pulling this view onto this monitor. There has to be a way to get this back into the visible space so that I can work on it. I have tried double clicking on the view icon in the organizer which normally brings the view forward but it is not coming into view. What can I do? Is this really a bug that has been around this whole time?

• JavaScript on Android randomly stops working

  - by AndersWid

  Hi! I have an application that uses a WebView and a html-page with javascript functions. Randomly the JavaScript functions doesn't seem to be called. It works up to a random point (I have looked at this bug all day) can only be produced on hardware (HTC Legend) not on emulator. Basicly I'm using callback to javaScript whenever the user presses a button, these callbacks tell the html to redraw using javaScript functions. mHandler.post(new Runnable() { public void run() { mWebView.loadUrl("javascript:getDataLine()"); } }); The first line in this javaScript code is an alert that says that it has started, so that I can see that it's working. Settings alerts or console.log's everywhere won't help as it seems the problem is in the webview or in Android itself. I need a way to see what's going on in the background. Maybe see if a previous call failed and stalled the thread or something.
