  • Mercurial: a few questions all related to .hgignore

    - by WizardOfOdds
    I've been working for a long time with a .hgignore file that was fine and recently added one new type of files to ignore. When running "hg status", I noticed this: M .hgignore So Mercurial considers the .hgignore to be a file that needs to be tracked (if it's a the root of the project). Now I've read various docs but my points weren't specifically adressed so here are some very detailed questions which hopefully can help me figure this out (it would be great is someone answering could quote and address these three points [even with a simply yes/no answer for each question]): Should .hgignore be at the root of the project? (I guess it should, seen that a developer can potentially be working on several projects which would all have different .hgignore requirements) Can .hgignore be ignored be Mercurial? If it can be ignored, should .hgignore be ignored by Mercurial (which is different than the previous question) In the case where .hgignore should not be ignored, can't some really bad thing happens if you suddenly rollback way earlier, when a really old and incomplete .hgignore was used? I think I saw weird things happening with certain per-user IDE project files (I'm not saying all IDEs project files are per-user only, but some definitely are) that were supposed to be ignored, but then the user rolls back to an old version, where an old .hgignore gets used, and then suddenly files supposed to be ignored are committed because the old .hgignore didn't exclude these.

  • Django aggregation query on related one-to-many objects

    - by parxier
    Here is my simplified model: class Item(models.Model): pass class TrackingPoint(models.Model): item = models.ForeignKey(Item) created = models.DateField() data = models.IntegerField() In many parts of my application I need to retrieve a set of Item's and annotate each item with data field from latest TrackingPoint from each item ordered by created field. For example, instance i1 of class Item has 3 TrackingPoint's: tp1 = TrackingPoint(item=i1, created=date(2010,5,15), data=23) tp2 = TrackingPoint(item=i1, created=date(2010,5,14), data=21) tp3 = TrackingPoint(item=i1, created=date(2010,5,12), data=120) I need a query to retrieve i1 instance annotated with tp1.data field value as tp1 is the latest tracking point ordered by created field. That query should also return Item's that don't have any TrackingPoint's at all. If possible I prefer not to use QuerySet's extra method to do this. That's what I tried so far... and failed :( Item.objects.annotate(max_created=Max('trackingpoint__created'), data=Avg('trackingpoint__data')).filter(trackingpoint__created=F('max_created')) Any ideas?

  • Execution time in nano seconds and related issues

    - by anup
    Hi All, I am using the following code to compute execution time in milli-secs. struct timespec tp; if (clock_gettime (CLOCK_REALTIME, &tp) == 0) return ((tp.tv_sec * 1000000000) + tp.tv_nsec); else return ; Can you please tell me whether this is correct? Let's name this function comptime_nano(). Now, I write the following code in main() to check execution times of following operations. unsigned long int a, b, s1, s3; a = (unsigned long int)(1) << 63; b = (unsigned long int)(1) << 63; btime = comptime_nano(); s1 = b >> 30; atime = comptime_nano(); printf ("Time =%ld for %lu\n", (atime - btime), s1); btime = comptime_nano(); s3 = a >> 1; atime = comptime_nano(); printf ("Time =%ld for %lu\n", (atime - btime), s3); To my surprise, the first operation takes about roughly 4 times more time than the second. Again, if I change the relative ordering of these operations, the respective timings change drastically. Please comment...

  • Zend Framework: Zend_translate and routing related issue

    - by Dan
    I have implemented Zend_Navigation, Zend_Translate in my application. The routing is setup in Bootstrap.php like below. $fc = Zend_Controller_Front::getInstance(); $zl=new Zend_Locale(); Zend_Registry::set('Zend_Locale',$zl); $lang=$zl->getLanguage().'_'.$zl->getRegion(); $router = $fc->getRouter(); $route = new Zend_Controller_Router_Route(':lang/:module/:controller/:action/*', array( 'lang'=>$lang, 'module'=>'default', 'controller'=>'index', 'action'=>'index' )); $router->addRoute('default', $route); $fc->setRouter($router); $fc->registerPlugin( new Plugin_LanguageSetup()); in LaunguageSetup Plugin i have defined the dispatchLoopStartup method to do the checking of the language param public function dispatchLoopStartup(Zend_Controller_Request_Abstract $request) { $this->createLangUrl($request); $this->_language = $request->getParam('lang'); if ((!isset($this->_language)) || !in_array($this->_language, $this->_languagesArray)) { $this->_language = 'en_US'; $request->setParam('lang', 'en_US'); } $file = APPLICATION_PATH.$this->_directory.$this->_language.'.csv'; $translate = new Zend_Translate('csv', $file, $this->_language); Zend_Registry::set('Zend_Translate', $translate); $zl = Zend_Registry::get('Zend_Locale'); $zl->setLocale($this->_language); Zend_Registry::set('Zend_Locale', $zl); // $fc = Zend_Controller_Front::getInstance(); // $router = $fc->getRouter(); // $route = new Zend_Controller_Router_Route(':lang/:module/:controller/:action/*', array( // 'lang'=>$this->_language, 'module'=>'default', 'controller'=>'index', 'action'=>'index' // )); // $router->addRoute('default', $route); // $fc->setRouter($router); } What happen is the language always have the default value, the 'lang' param never default lang value in route, even if i type it in the address bar manually i.e /en_US/module/controller/action/ It always get revert back to the default Zend_locale(); Only way i can fix it is to setup the route again in the plugin and inject a correct language value as default. Any Idea why?

  • django model Form. Include fields from related models

    - by Tom
    Hi. I have a model, called Student, which has some fields, and a OneToOne relationship with user (django.contrib.auth.User). class Student(models.Model): phone = models.CharField(max_length = 25 ) birthdate = models.DateField(null=True) gender = models.CharField(max_length=1,choices = GENDER_CHOICES) city = models.CharField(max_length = 50) personalInfo = models.TextField() user = models.OneToOneField(User,unique=True) Then, I have a ModelForm for that model class StudentForm (forms.ModelForm): class Meta: model = Student Using the fields attribute in class Meta, i've managed to show only some fields in a template. However, can I indicate which user fields to show? Something as: fields =('personalInfo','user.username') is currently not showing anything. Works with only StudentFields though/ Thanks in advance.

    Hullo, this is Damien. I am new to programming and to StackOverflow community. Our professor once said that "the whole point of programming is creating abstractions." His explanation however went right over my head. Please explain the meaning of this sentence in simple words -- something that a noob like me can understand. Thank you!

  • Core Data 1-to-many relationship: List all related objects as section header in UITableView

    - by Snej
    Hi: I struggle with Core Data on the iPhone about the following: I have a 1-to-many relationship in Core Data. Assume the entities are called recipe and category. A category can have many recipes. I accomplished to get all recipes listed in a UITableView with section headers named after the category. What i want to achieve is to list all categories as section header, even those which have no recipe: category1 <--- this one should be displayed too category2 recipe_x recipe_y category3 recipe_z NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Recipe" inManagedObjectContext:managedObjectContext]; [fetchRequest setEntity:entity]; [fetchRequest setFetchBatchSize:10]; NSSortDescriptor *sortDescriptor1 = [[NSSortDescriptor alloc] initWithKey:@"category.categoryName" ascending:YES]; NSSortDescriptor *sortDescriptor2 = [[NSSortDescriptor alloc] initWithKey:@"recipeName" ascending:YES]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor1,sortDescriptor2, nil]; [fetchRequest setSortDescriptors:sortDescriptors]; NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:managedObjectContext sectionNameKeyPath:@"category.categoryName" cacheName:@"Recipes"]; What is the most elegant way to achieve this with core data?

  • SQLite on iPhone - Techniques for tracking down multithreading-related bugs

    - by Jasarien
    Hey guys, I'm working with an Objective-C wrapper around SQLite that I didn't write, and documentation is sparse... It's not FMDB. The people writing this wrapper weren't aware of FMDB when writing this code. It seems that the code is suffering from a bug where database connections are being accessed from multiple threads -- which according to the SQLite documentation won't work if the if SQLite is compiled with SQLITE_THREADSAFE 2. I have tested the libsqlite3.dylib provided as part of the iPhone SDK and seen that it is compiled in this manner, using the sqlite_threadsafe() routine. Using the provided sqlite library, the code regularly hits SQLITE_BUSY and SQLITE_LOCKED return codes when performing routines. To combat this, I added some code to wait a couple of milliseconds and try again, with a maximum retry count of 50. The code didn't contain any retry logic prior to this. Now when a sqlite call returns SQLITE_BUSY or SQLITE_LOCKED, the retry loop is invoked and the retry returns SQLITE_MISUSE. Not good. Grasping at straws, I replaced the provided sqlite library with a version compiled by myself setting SQLITE_THREADSAFE to 1 - which according to the documentation means sqlite is safe to be used in a multithreaded environment, effectively serialising all of the operations. It incurs a performance hit, that which I haven't measured, but it ridded the app of the SQLITE_MISUSE happening and seemed to not need the retry logic as it never hit a busy or locked state. What I would rather do is fix the problem of accessing a single db connection from multiple threads, but I can't for the life of me find where it's occurring. So if anyone has any tips on locating multithreaded bugs I would be extremely appreciative. Thanks in advance.

  • Converting a VMware player image from non-persistant to persistant

    - by Journeyman Geek
    I'm pondering setting up a virtual machine to generate app-v (since i got mdop from school) or thinapp application virtualisation packages. Ideally with either of these, i should work off a fresh system do the install, then copy out the packages produced. I'd like to not have to reinstall windows per package to get a fresh, unmodified stock copy of windows. I'm aware that its possible to make a hard disk image persistant in vmware player (one of my lecturers did it, but he's in another country). I'm wondering how would i convert a persistant image to a non persistant one? I'm currently running vmware player 4, with windows 7 guest and host.

  • Filemaker - Getting field values from related table

    - by foobar
    I have the following setup in Filemaker Pro 10. Table1 with: id_table1, related_names Table2 with: id_table2, name, include and a joint-table with: id_table1, id_table2 Now I want either make related_names a calculated field or write a script that sets related_names to a comma separated list of all names which are connected through the joint-table and have Table2.include = True. So for example a data set could look like: Table1 id_table1, related_names 1, "foo,bar" 2, "foo" 3, "" joint-table id_table1, id_table2 1,1 1,2 1,3 2,1 Table2 id_table2, name, include 1, foo, True 2, bar, True 3, baz, False After searching the internet for a few hours the closest I came was a calculated field with list(join-table::id_table2) which gives me a list with a all the id_table2's. But now I would need to find the appropriate records in table2 and check the include field. I hope the problem is clear. any help is highly appreciated.

  • Must read books for a programming team leader

    - by takeshin
    As a programming team leader, which books do you recommend? Books about HR, good programming practices etc. I have recently seen PHP Team Development but it is not mind blowing for experienced developers. One of the best I can recommend is Microsoft Manual of Style for Technical Publications, which helped me a lot in improving the language and practices of documenting the code.

  • SEO - Problems possibly related to 301 Moved Permanently

    - by ILMV
    Right, here's the story: We have had a website for one of our brands now for many years, the site design was very bad and recently did a complete overhaul, mostly design, but also some of the backend code. The original site was using links such as this example.com/products/item/127 and thus I wanted to change them to be move user friendly, especially to include the product name, the same link now reads example.com/product/127/my-jucy-product/. Since our switch over we have seen our Google results take a beating (we were on the first page for our normal search terms, now we're nearer the 4th!). The other problem we're having is that the links to the old products haven't updated to the new links despite me coding a 301 redirect from old to new. The 301 is not being fired from .htaccess, but in our PHP framework. I had a look at how the site is being loaded from a old link that is still in Google and here's what firebug is reporting: GET <google link> 302 Found GET example.com/products/item/127 302 Found GET example.com/products/item/127 301 Moved Permanently GET example.com/product/127/my-jucy-product/ 302 Found So the Google link has a 302, good. But when the old link comes in our framework is returning a 302! It's only afterwards when it finally hits the right part of the framework does it 301, so here's my question: Is the reason our old links have not changed and our Google Ranking has significantly nose dived because Google is seeing a 302 before the 301? At the time I was reluctant to mess with our .htaccess because it had become pretty complicated and I was under some pretty intense time constraints, now I'm wondering whether this was an incorrect disicion and perhaps I should revisit it. Many thanks! Edit Bugger, just signed up to the Webmaster Tools and I'm getting redirect errors all over the place, hundreds of them! I think this is my problem.

  • IIS 6.0 subdomains with host headers and non existent subdomains

    - by Mustafakidd
    Hey Everyone - We have a wildcard A-Record pointing to our IP and have a number of sites running on IIS 6 with host headers and have a a wildcard SSL certificate for the domain so that each site can run under SSL. For example: https://A.foo.com https:/B.foo.com https:/C.foo.com Everything is working well but I noticed that when we type a non existent subdomain, say D.foo.com, it redirects to A.foo.com. Any idea why that is or how I can change that? I think we may have set up the A.foo.com site before we applied the wildcard A-record with our domain provider and before we had set up the SSL cert. Thanks.

  • Removing non-breaking spaces from strings using Python

    Hello: I am having some trouble with a very basic string issue in Python (that I can't figure out). Basically, I am trying to do the following: '# read file into a string myString = file.read() '# Attempt to remove non breaking spaces myString = myString.replace("\u00A0"," ") '# however, when I print my string to output to console, I get: Foo **<C2><A0>** Bar I thought that the "\u00A0" was the escape code for unicode non breaking spaces, but apparently I am not doing this properly. Any ideas on what I am doing wrong?

I figured I was getting this error because I did not have JAVA_HOME set however I added this to bashrc as: export JAVA_HOME=/usr/lib/jvm/java-1.6.0-openjdk and have confirmed: echo $JAVA_HOME /usr/lib/jvm/java-1.6.0-openjdk I can produce a similar error by removing my JAVA_HOME variable on windows: =================Processing FREDERICKSBURG_1.3======================= ERROR IN TESTING cannot convert instance of class org.jruby.RubyString to char C:/work/Code/geografikos/lib/sentence_splitter/splitter.rb:21:in `to_java' C:/work/Code/geografikos/lib/sentence_splitter/splitter.rb:21:in `split' C:/work/Code/geografikos/lib/models/page.rb:103:in `sentences' C:/work/Code/geografikos/lib/extractor/lingpipe_svm.rb:34:in `extract' C:/work/Code/geografikos/lib/extractor/geo_controller.rb:9:in `process' C:/work/Code/geografikos/lib/extractor/geo_controller.rb:8:in `each' C:/work/Code/geografikos/lib/extractor/geo_controller.rb:8:in `process' C:/work/Code/geografikos/lib/extractor/geo_controller.rb:6:in `each' C:/work/Code/geografikos/lib/extractor/geo_controller.rb:6:in `process' C:/work/Code/geografikos/lib/statistics.rb:111:in `generate_all' C:/work/Code/geografikos/lib/statistics.rb:105:in `each' C:/work/Code/geografikos/lib/statistics.rb:105:in `generate_all' run.rb:56 It is obviously not exactly the same but I have a feeling this has to do with the java path. You can probably derive from the error that I am just trying to convert a ruby variable to java using to_java. This works fine on my windows machine and I have confirmed the gems are the same but I don't think this has to do with gems. I lied. I changed my JAVA_HOME back on my windows machine and this error still occurs. So now the code doesn't run on either machine. I recently installed git on my windows machine and added the code to a repository. But I haven't really done anything with it. All it said was it will convert all LF to CRLF...That shouldn't change anything though should it? Any ideas on why I am now getting these errors? I haven't changed anything on my windows machine in months except for installing git.
