  • Merging: hg/git vs. svn

    - by stmax
    I often read that hg (and git and...) are better at merging than svn but I have never seen practical examples of where hg/git can merge something where svn fails (or where svn needs manual intervention). Could you post a few step-by-step lists of branch/modify/commit/...-operations that show where svn would fail while hg/git happily moves on? Practical, not highly exceptional cases please... Some background: we have a few dozen developers working on projects using svn, with each project (or group of similar projects) in its own repo. We know how to apply release- and feature-branches so we don't run into problems very often (i.e. we've been there, but we've learned to overcome joel's problems of "one programmer causing trauma to the whole team" or "needing six developers for two weeks to reintegrate a branch"). We have release-branches that are very stable and only used to apply bugfixes. We have trunks that should be stable enough to be able to create a release within one week. And we have feature-branches that single developers or groups of developers can work on. Yes, they are deleted after reintegration so they don't clutter up the repository. ;) So I'm still trying to find the advantages of hg/git over svn. I'd love to get some hands-on experience, but there aren't any bigger projects we could move to hg/git yet, so I'm stuck with playing with small artifical projects that only contain a few made up files. And I'm looking for a few cases where you can feel the impressive power of hg/git, since so far I have often read about them but failed to find them myself.

  • How do I add programmatically-generated new files to source control?

    - by Alex Basson
    This is something I've never really understood about source control, specifically Subversion (the only source control I've ever used, which isn't saying much). I'm considering moving to git or Mercurial, so if that affects the answer to my question, please indicate as such. Ok. As I understand it, every time I create a new file, I have to tell SVN about it, so that it knows to add it to the repository and place it under control. Something like: svn add newfile That's fine if I'm the one creating the file: I know I created it, I know its name, I know where it lives, so it's easy to tell SVN about it. But now suppose I'm using a framework of some kind, like Rails, Django, Symfony, etc., and suppose I've already done the initial commit. All of these frameworks create new files programmatically, often many at once, in different directories, etc. etc. How do I tell the source control about these new files? Do I have to hunt each one of them down individually and add them? Is there an easier way? (Or am I possibly misunderstanding something fundamental about source control?)

  • DDD: Persisting aggregates

    - by Mosh
    Hello, Let's consider the typical Order and OrderItem example. Assuming that OrderItem is part of the Order Aggregate, it an only be added via Order. So, to add a new OrderItem to an Order, we have to load the entire Aggregate via Repository, add a new item to the Order object and persist the entire Aggregate again. This seems to have a lot of overhead. What if our Order has 10 OrderItems? This way, just to add a new OrderItem, not only do we have to read 10 OrderItems, but we should also re-insert all these 10 OrderItems again. (This is the approach that Jimmy Nillson has taken in his DDD book. Everytime he wants to persists an Aggregate, he clears all the child objects, and then re-inserts them again. This can cause other issues as the ID of the children are changed everytime because of the IDENTITY column in database.) I know some people may suggest to apply Unit of Work pattern at the Aggregate Root so it keeps track of what has been changed and only commit those changes. But this violates Persistence Ignorance (PI) principle because persistence logic is leaking into the Domain Model. Has anyone thought about this before? Mosh

  • Uncompress OpenOffice files for better storage in version control

    - by Craig McQueen
    I've heard discussion about how OpenOffice (ODF) files are compressed zip files of XML and other data. So making a tiny change to the file can potentially totally change the data, so delta compression doesn't work well in version control systems. I've done basic testing on an OpenOffice file, unzipping it and then rezipping it with zero compression. I used the Linux zip utility for my testing. OpenOffice will still happily open it. So I'm wondering if it's worth developing a small utility to run on ODF files each time just before I commit to version control. Any thoughts on this idea? Possible better alternatives? Secondly, what would be a good and robust way to implement this little utility? Bash shell that calls zip (probably Linux only)? Python? Any gotchas you can think of? Obviously I don't want to accidentally mangle a file, and there are several ways that could happen. Possible gotchas I can think of: Insufficient disk space Some other permissions issue that prevents writing the file or temporary files ODF document is encrypted (probably should just leave these alone; the encryption probably also causes large file changes and thus prevents efficient delta compression)

  • How can I save an entire list of items true or false?

    - by JZ
    I'm following Ryan Bates, Railscast episode 52 and I've translated relevant parts of the code to work with Rails 3.0.0.beta2. In Ryan's case, he simply marks items incomplete and saves a timestamp. If an Item contains a timestamp the model returns the item in the completed list. I'm attempting to save ALL values true or false, depending on whether the check_box_tag is selected or not (using boolean). I am able to save ONLY selected items, true or false. How can I save an entire list of items true or false, depending on whether the checkbox is selected? The following is my attempt: controller logic: def yardsign Add.update_all(["yardsign=?", true], :id => params[:yard_ids]) redirect_to adds_path end html.erb: <%= form_tag yardsign_adds_path, :method => :put do %> <% @adds.each do |add| %> <td><%= check_box_tag "yard_ids[]", add.id %></td> <% end %> <% end %> routes.rb resources :adds do collection do put :yardsign end end Terminal Started POST "/adds/yardsign" for 127.0.0.1 at 2010-04-15 19:22:49 Processing by AddsController#yardsign as HTML Parameters: {"commit"=>"Update", "yardsigntakers"=>["1", "2"], "authenticity_token"=>"3arhsxg/Ky+0W7RNM2T3QditMTJmOnLR5CqmMYWN4Qw="} User Load (0.3ms) SELECT "users".* FROM "users" WHERE ("users"."id" = 1) LIMIT 1 SQL (1.8ms) UPDATE "adds" SET yardsign='t' WHERE ("adds"."id" IN (1, 2)) Redirected to http://localhost:3000/adds

  • parameter for xcodebuild for using latest sdk.

    - by Maciek Sawicki
    I using ant exec task to execute xcodebuild to build some iOS projects hudson. I would like to be able to crate script that way that allows not to specify sdk version, because after updating sdk on hudson slave or my iOS projects all my projects failing.... There is is nice option in xcode since sdk 4.2 in target setup Base SDK - Latest iOS and I don't have to provide -sdk param in xcodebuild command, but then (i think) it's taken from xcode project and it's bad because then some one can change target from simulator to device accidentally during commit. I need something that is constant. I will prefer not to use env variable because I would like to be able to run this ant task also on dev machines and would like not have to renember about setting it on all machines. Unfortunately xcodebuild -showsdk gives only: Mac OS X SDKs: Mac OS X 10.4 -sdk macosx10.4 Mac OS X 10.5 -sdk macosx10.5 Mac OS X 10.6 -sdk macosx10.6 iOS SDKs: iOS 4.2 -sdk iphoneos4.2 iOS Simulator SDKs: Simulator - iOS 3.2 -sdk iphonesimulator3.2 Simulator - iOS 4.0 -sdk iphonesimulator4.0 Simulator - iOS 4.1 -sdk iphonesimulator4.1 Simulator - iOS 4.2 -sdk iphonesimulator4.2 I need something like -sdk iphoneosLatest. My only idea is to pare output of xcodebuild -showsdk with some script, but I don't like this idea.

  • Newbie T-SQL dynamic stored procedure -- how can I improve it?

    - by Andy Jones
    I'm new to T-SQL; all my experience is in a completely different database environment (Openedge). I've learned enough to write the procedure below -- but also enough to know that I don't know enough! This routine will have to go into a live environment soon, and it works, but I'm quite certain there are a number of c**k-ups and gotchas in it that I know nothing about. The routine copies data from table A to table B, replacing the data in table B. The tables could be in any database. I plan to call this routine multiple times from another stored procedure. Permissions aren't a problem: the routine will be run by the dba as a timed job. Could I have your suggestions as to how to make it fit best-practice? To bullet-proof it? ALTER PROCEDURE [dbo].[copyTable2Table] @sdb varchar(30), @stable varchar(30), @tdb varchar(30), @ttable varchar(30), @raiseerror bit = 1, @debug bit = 0 as begin set nocount on declare @source varchar(65) declare @target varchar(65) declare @dropstmt varchar(100) declare @insstmt varchar(100) declare @ErrMsg nvarchar(4000) declare @ErrSeverity int set @source = '[' + @sdb + '].[dbo].[' + @stable + ']' set @target = '[' + @tdb + '].[dbo].[' + @ttable + ']' set @dropStmt = 'drop table ' + @target set @insStmt = 'select * into ' + @target + ' from ' + @source set @errMsg = '' set @errSeverity = 0 if @debug = 1 print('Drop:' + @dropStmt + ' Insert:' + @insStmt) -- drop the target table, copy the source table to the target begin try begin transaction exec(@dropStmt) exec(@insStmt) commit end try begin catch if @@trancount > 0 rollback select @errMsg = error_message(), @errSeverity = error_severity() end catch -- update the log table insert into HHG_system.dbo.copyaudit (copytime, copyuser, source, target, errmsg, errseverity) values( getdate(), user_name(user_id()), @source, @target, @errMsg, @errSeverity) if @debug = 1 print ( 'Message:' + @errMsg + ' Severity:' + convert(Char, @errSeverity) ) -- handle errors, return value if @errMsg <> '' begin if @raiseError = 1 raiserror(@errMsg, @errSeverity, 1) return 1 end return 0 END Thanks!

  • Using Git to work with subversion: Ignoring modifications to tracked files

    - by Chris Nicola
    I am currently working with a subversion repository but I am using git to work locally on my machine. It makes work much easier, but it also makes some of the bad behavior going on in the subversion repo quite glaring and that creates problems for me. There is a somewhat complex local build process after pulling down the code and it creates (and unfortunately modifies) a number of files. Obviously these changes are not meant to be committed back to the repository. Unfortunately the build process is actually modifying some tracked files (yes, most likely because someone mistakenly committed these build artifacts at some point to the subversion repository). Since these are modifications adding them to my ignore file does nothing for me. I can avoid checking these changes back it, I simple don't stage or commit them, but having unstaged local changes means I can't rebase without first cleaning them up. What I would like to know is if there any way to ignore future changes to a set of tracked files? Alternatively, is there another way to handle the problem I am having, or will I just have to tell whoever checked in these files to clean them up?

  • PostgreSQL insert on primary key failing with contention, even at serializable level

    - by Steven Schlansker
    I'm trying to insert or update data in a PostgreSQL db. The simplest case is a key-value pairing (the actual data is more complicated, but this is the smallest clear example) When you set a value, I'd like it to insert if the key is not there, otherwise update. Sadly Postgres does not have an insert or update statement, so I have to emulate it myself. I've been working with the idea of basically SELECTing whether the key exists, and then running the appropriate INSERT or UPDATE. Now clearly this needs to be be in a transaction or all manner of bad things could happen. However, this is not working exactly how I'd like it to - I understand that there are limitations to serializable transactions, but I'm not sure how to work around this one. Here's the situation - ab: => set transaction isolation level serializable; a: => select count(1) from table where id=1; --> 0 b: => select count(1) from table where id=1; --> 0 a: => insert into table values(1); --> 1 b: => insert into table values(1); --> ERROR: duplicate key value violates unique constraint "serial_test_pkey" Now I would expect it to throw the usual "couldn't commit due to concurrent update" but I'm guessing since the inserts are different "rows" this does not happen. Is there an easy way to work around this?

    I try to learn the has_and_belongs_to_many relationship between my 2 fresh new and simple models Product and Author, where a Product can have many authors and where author can have a lots of products. I wrote this : class Author < ActiveRecord::Base has_and_belongs_to_many :products end class Product < ActiveRecord::Base has_and_belongs_to_many :authors end In the partial form of view for the products, I have : <p>Products</p> <%= collection_select(:product, :author_ids, @authors, :id, :name, :prompt => " ", :multiple => true) %> but when I hit the update button, I get this strange message I can't resolve myself : NoMethodError in ProductsController#update undefined method `reject' for "1":String Rails.root: /home/stephane/www/HABTM Application Trace | Framework Trace | Full Trace app/controllers/products_controller.rb:63:in block in update' app/controllers/products_controller.rb:62:inupdate' Request Parameters: {"utf8"="✓", "_method"="put", "authenticity_token"="2GlTssOFjTVZ9BikrIFgx22cdTOIJuAB70liYhhLf+4=", "product"={"title"="Le trésor des Templiers", "original_title"="", "number"="1", "added_by"="", "author_ids"="1"}, "commit"="Update Product", "id"="1"} What's wrong ?

  • Update Related Entity Of Detached Entity

    - by Hemslingo
    I'm having an issue updating an entity with multiple related entities. I've got a very simple model which consists of an article entity and a list of categories the article can be related to. You can choose from a check box list which of these categories are associated to it...which works fine. The problem crops up when I actually come to update an existing entity using the dbContext. As I am updating this entity, I have already detached it from the context ready to re-attach it later so the update can execute properly. I can see that after I posting the model, the category(s) are being added to the article entity just fine and it looks like it updates in the repository with no errors occurring. When I look in the database the article has updated as normal but the category(s) have not. Here is my (simplified) update code... public virtual bool Attach(T entity) { _dbContext.Entry(entity).State = EntityState.Modified; _dbSet.Attach(entity); return this.Commit(); } Any help will be much appreciated.

  • Simplest way to handle and display errors in a Python Pylons controller without a helper class

    - by ensnare
    I have a class User() that throw exceptions when attributes are incorrectly set. I am currently passing the exceptions from the models through the controller to the templates by essentially catching exceptions two times for each variable. Is this a correct way of doing it? Is there a better (but still simple) way? I prefer not to use any third party error or form handlers due to the extensive database queries we already have in place in our classes. Furthermore, how can I "stop" the chain of processing in the class if one of the values is invalid? Is there like a "break" syntax or something? Thanks. >>> u = User() >>> u.name = 'Jason Mendez' >>> u.password = '1234' Traceback (most recent call last): File "<stdin>", line 1, in <module> File "topic/model/user.py", line 79, in password return self._password ValueError: Your password must be greater than 6 characters In my controller "register," I have: class RegisterController(BaseController): def index(self): if request.POST: c.errors = {} u = User() try: u.name = c.name = request.POST['name'] except ValueError, error: c.errors['name'] = error try: u.email = c.email = request.POST['email'] except ValueError, error: c.errors['email'] = error try: u.password = c.password = request.POST['password'] except ValueError, error: c.errors['password'] = error try: u.commit() except ValueError, error: pass return render('/register.mako')

  • How can I sync files in two different git repositories (not clones) and maintain history?

    - by brian d foy
    I maintain two different git repos that need to share some files, and I'd like the commits in one repo to show up in the other. What's a good way to do that for ongoing maintenance? I've been one of the maintainers of the perlfaq (Github), and recently I fell into the role of maintaining the Perl core documentation, which is also in git. Long before I started maintaining the perlfaq, it lived in a separate source control repository. I recently converted that to git. Periodically, one of the perl5-porters would sync the shared files in the perlfaq repo and the perl repo. Since we've switched to git, we'e been a bit lazy converting the tools, and I'm now the one who does that. For the time being, the two repos are going to stay separate. Currently, to sync the FAQ for a new (monthly) release of perl, I'm almost ashamed to say that I merely copy the perlfaq*.pod files in the perlfaq repo and overlay them in the perl repo. That loses history, etc. Additionally, sometimes someone makes a change to those files in the perl repo and I end up overwriting it (yes, check git diff you idiot!). The files do not have the same paths in the repo, but that's something that I could change, I think. What I'd like to do, in the magical universe of rainbows and ponies, is pull the objects from the perlfaq repo and apply them in the perl repo, and vice-versa, so the history and commit ids correspond in each. Creating patches works, but it's also a lot work to manage it Git submodules seem to only work to pull in the entire external repo I haven't found something like svn's file externals, but that would work in both directions anyway I'd love to just fetch objects from one and cherry-pick them in the other What's a good way to manage this?

  • SQL Server lock/hang issue

    - by mattwoberts
    Hi, I'm using SQL Server 2008 on Windows Server 2008 R2, all sp'd up. I'm getting occasional issues with SQL Server hanging with the CPU usage on 100% on our live server. It seems all the wait time on SQL Sever when this happens is given to SOS_SCHEDULER_YIELD. Here is the Stored Proc that causes the hang. I've added the "WITH (NOLOCK)" in an attempt to fix what seems to be a locking issue. ALTER PROCEDURE [dbo].[MostPopularRead] AS BEGIN SET NOCOUNT ON; SELECT c.ForeignId , ct.ContentSource as ContentSource , sum(ch.HitCount * hw.Weight) as Popularity , (sum(ch.HitCount * hw.Weight) * 100) / @Total as Percent , @Total as TotalHits from ContentHit ch WITH (NOLOCK) join [Content] c WITH (NOLOCK) on ch.ContentId = c.ContentId join HitWeight hw WITH (NOLOCK) on ch.HitWeightId = hw.HitWeightId join ContentType ct WITH (NOLOCK) on c.ContentTypeId = ct.ContentTypeId where ch.CreatedDate between @Then and @Now group by c.ForeignId , ct.ContentSource order by sum(ch.HitCount * hw.HitWeightMultiplier) desc END The stored proc reads from the table "ContentHit", which is a table that tracks when content on the site is clicked (it gets hit quite frequently - anything from 4 to 20 hits a minute). So its pretty clear that this table is the source of the problem. There is a stored proc that is called to add hit tracks to the ContentHit table, its pretty trivial, it just builds up a string from the params passed in, which involves a few selects from some lookup tables, followed by the main insert: BEGIN TRAN insert into [ContentHit] (ContentId, HitCount, HitWeightId, ContentHitComment) values (@ContentId, isnull(@HitCount,1), isnull(@HitWeightId,1), @ContentHitComment) COMMIT TRAN The ContentHit table has a clustered index on its ID column, and I've added another index on CreatedDate since that is used in the select. When I profile the issue, I see the Stored proc executes for exactly 30 seconds, then the SQL timeout exception occurs. If it makes a difference the web application using it is ASP.NET, and I'm using Subsonic (3) to execute these stored procs. Can someone please advise how best I can solve this problem? I don't care about reading dirty data... Thanks

    I'm having an extremely frustrating time getting some images to upload.

  • ADO.NET zombie transaction bug? How to ensure that commands will not be executed on implicit transac

    - by TN
    e.g. When deadlock occurs, following SQL commands are successfully executed, even if they have assigned SQL transaction that is after rollback. It seems, it is caused by a new implicit transaction that is created on SQL Server. Someone could expect that ADO.NET would throw an exception that the commands are being executed on a zombie transaction. However, such exception is not thrown. (I think this is a bug in ASP.NET.) Moreover, because of zombie transaction the final Dispose() silently ignores the rollback. Any ideas, how can I ensure that nobody can execute commands on implicit transaction? Or, how to check that transaction is zombie? I found that Commit() and Rollback() check for zombie transaction, however I can call them for a test:) I also found that also reading IsolationLevel will do the check, but I am not sure whether simple calling transaction.IsolationLevel.ToString(); will not be removed by a future optimizer. Or do you know any other safe way invoke a getter (without using reflection or IL emitting)?

  • When do you tag your software project?

    - by WilhelmTell of Purple-Magenta
    I realize there are various kinds of software projects: commercial (for John Doe) industrial (for Mr. Montgomery Burns) successful open-source (with audience larger than, say, 10 people) personal projects (with audience size in the vicinity of 1). each of which release a new version of their product on difference conditions. I'm particularly interested in the case of personal projects and open-source projects. When, or under what conditions, do you make a new release of any kind? Do you subscribe to a fixed recurring deadline such as every two weeks? Do you commit to a release of at least 10 minor fixes, or one major fix? Do you combine the two conditions such as at least one condition must hold, or both must hold? I reckon this is a subjective question. I ask this question in light of searching for tricks to keep my projects alive and kicking. Sometimes my projects are active but look as if they aren't because I don't have the confidence to make a release or a tag of any sort for a long time -- in the order of months.

  • Query on object id in VQL

    - by Banang
    I'm currently working with the versant object database (using jvi), and have a case where I need to query the database based on an object id. What I'm trying to achieve is something along the lines of Employee employee = new Employee("Mr. Pickles"); session.commit(); FundVQLQuery q = new FundVQLQuery(session, "select * from Employee employee where employee = $1"); q.bind(employee); q.execute(); However, I'm finding out the hard way (I get an EVJ_NOT_A_VALID_KEY_TYPE error thrown at me) that this is infact not the way to do it. Anyone got any experience in working with VQL? Your help is much apreciated! A small clarification: The problem is I'm running some performance tests on the database using the pole position framework, and one of the tests in that framework requires me to fetch an object from the database using either an object reference or a low level object id. Thus, I'm not allowed to reference specific fields in the employee object, but must perform the query on the object in its entirety. So, it's not allowed for me to go "select * from Employee e where e.id = 4", I need it to use the entire object. Accepted answer: Since there is some sort of lunacy magic built into SO that prevents me to mark an accepted answer after a bounty has run out, readers should know that the answer posted by Chris Holmes solves this issue. Readers are encouraged to up-vote his post to further signalize the correctness of his answer to any future readers of this thread.

  • Django m2m form appearing fields

    - by dana
    I have a classroom application,and a follow relation. Users can follow each other and can create classrooms.When a user creates a classroom, he can invite only the people that are following him. The Classroom model is a m2m to User table. i have in models. py: class Classroom(models.Model): creator = models.ForeignKey(User) classname = models.CharField(max_length=140, unique = True) date = models.DateTimeField(auto_now=True) open_class = models.BooleanField(default=True) members = models.ManyToManyField(User,related_name="list of invited members") and in models.py of the follow application: class Relations(models.Model): initiated_by = models.ForeignKey(User, editable=False) date_initiated = models.DateTimeField(auto_now=True, editable = False) follow = models.ForeignKey(User, editable = False, related_name = "follow") date_follow = models.DateTimeField(auto_now=True, editable = False) and in views.py of the classroom app: def save_classroom(request, username): if request.method == 'POST': u = User.objects.get(username=username) form = ClassroomForm(request.POST, request.FILES) if form.is_valid(): new_obj = form.save(commit=False) new_obj.creator = request.user r = Relations.objects.filter(initiated_by = request.user) # new_obj.members = new_obj.save() return HttpResponseRedirect('.') else: form = ClassroomForm() return render_to_response('classroom/classroom_form.html', { 'form': form, }, context_instance=RequestContext(request)) i'm using a ModelForm for the classroom form, and the default view, taking in consideration my many to many relation with User table, in the field Members, is a list of all Users in my database. But i only want in that list the users that are in a follow relationship with the logged in user - the one who creates the classroom. How can i do that? Thanks!

  • IntegrityError: foreign key violation upon delete

    - by Lukasz Korzybski
    I have Order and Shipment model. Shipment has a foreign key to Order. class Order(...): ... class Shipment() order = m.ForeignKey('Order') ... Now in one of my views I want do delete order object along with all related objects. So I invoke order.delete(). I have Django 1.0.4, PostgreSQL 8.4 and I use transaction middleware, so whole request is enclosed in single transaction. The problem is that upon order.delete() I get: ... File "/usr/local/lib/python2.6/dist-packages/django/db/backends/__init__.py", line 28, in _commit return self.connection.commit() IntegrityError: update or delete on table "main_order" violates foreign key constraint "main_shipment_order_id_fkey" on table "main_shipment" DETAIL: Key (id)=(45) is still referenced from table "main_shipment". I checked in connection.queries that proper queries are executed in proper order. First shipment is deleted, after that django executes delete on order row: {'time': '0.000', 'sql': 'DELETE FROM "main_shipment" WHERE "id" IN (17)'}, {'time': '0.000', 'sql': 'DELETE FROM "main_order" WHERE "id" IN (45)'} Foreign key have ON DELETE NO ACTION (default) and is initially deferred. I don't know why I get foreign key constraint violation. I also tried to register pre_delete signal and manually delete shipment objects before delete on order is called, but it resulted in the same error. I can change ON DELETE behaviour for this key in Postgres but it would be just a hack, I wonder if anyone has a better idea what's going on here. There is also a small detail, my Order model inherits from Cart model, so it actually doesn't have id field but cart_ptr_id and after DELETE on order is executed there is also DELETE on cart, but it seems unrelated? to the shipment-order problem so I simplified it in the example.
