• VS 2008 debugger: How does it decide what Cassini port to run a web service under?

  - by BDW

  I have a VS 2008 solution that includes a web site and a web service. I'm developing both at once, and it's helpful to be able to debug from one into the other. It occasionally can't find the web service. If I look in the web.config, I find the port number it's looking at is not the port number it auto-runs the service in when I use the debugger. For example, the web.config reference says something like: add key="mynamespace.mywebservice" value="http://localhost:55765/mywebservice.asmx" When I hover over the Cassini port icon, I find that the web service is running in port 55382 (or some other non-55765 port). No wonder it can't find it. Is there a way to enforce that the port number it runs under is the one specified in the web config? And if it's not using the web config port number to figure out where to run it... where does it decide? I know in VS2005, there was a way to specify the port number to use when debugging, but I can't find that anywhere in the web service project in VS 2008. This is really going to cause problems as more developers come on to this project - how can I fix it? Deleting and re-adding the web services to the project fixes it, but I'd literally have to do it a couple times a day, not an ideal solution.

• What C++ templates issue is going on with this error?

  - by WilliamKF

  Running gcc v3.4.6 on the Botan v1.8.8 I get the following compile time error building my application after successfully building Botan and running its self test: ../../src/Botan-1.8.8/build/include/botan/secmem.h: In member function `Botan::MemoryVector<T>& Botan::MemoryVector<T>::operator=(const Botan::MemoryRegion<T>&)': ../../src/Botan-1.8.8/build/include/botan/secmem.h:310: error: missing template arguments before '(' token What is this compiler error telling me?

• JSP:Include not rendering the page correctly

  - by sreekanth

  am having trouble with including a jsp page with tag. This is what is happening. I making changes to a portlet application running on Websphere 7 server. This is the hierarchy of the jsp pages. blankPage.jsp --bookingViewTabs.jsp -- availableRooms.jsp meaning blankPage is included in bookingViewTabs which is inturn included in availableRooms.jsp I have 2 problems with this. (1). The blankPage.jsp does not render correctly on the screen. It gets cutoff (2). The other is in blankPage.jsp there is a form called "guestProfileSearchResultsFormId". this form has several hidden fields for data. example, "guestId" which is a child of that form and can be accessed formname.fieldname, but when i include that page into another jsp as the first include(there are several includes on the page) under the another form tag, the form field is not being rendered as a child of the form, but as a sibling of the form. If i change the order and include some other page and include this, it is working as it is supposed to have. meaning with children intact. I don't understand this behavior. I HAVE ATTACHED A GIF IMAGE OF WHAT I SEE ON THE BROWSER Any help is greatly appreciated. Thanks in advance

• CanCan polymorphic resource access problem

  - by Call 'naive' True

  Hi everybody, i don't quite understand how to restrict access to links in this particular case with CanCan. I always get "Edit" link displayed. So i believe the problem is in my incorrect definition of cancan methods(load_ and authorize_). I have CommentsController like that: class CommentsController < ApplicationController before_filter :authenticate_user! load_resource :instance_name => :commentable authorize_resource :article def index @commentable = find_commentable #loading our generic object end ...... private def find_commentable params.each { |name, value| if name =~ /(.+)_id$/ return $1.classify.constantize.includes(:comments => :karma).find(value) end } end end and i have in comments/index.html.erb following code that render file from other controller: <%= render :file => "#{get_commentable_partial_name(@commentable)}/show.html.erb", :collection => @commentable %> you can think about "#{get_commentable_partial_name(@commentable)}" like just "articles" in this case. Content of "articles/show.html.erb": <% if can? :update, @commentable %> <%= link_to 'Edit', edit_article_path(@commentable) %> | <% end %> my ability.rb: class Ability include CanCan::Ability def initialize(user) user ||= User.new # guest user if user.role? :admin can :manage, :all elsif user.role? :author can :read, [Article, Comment, Profile] can :update, Article, :user_id => user.id end end end relations with models is: class Comment < ActiveRecord::Base belongs_to :commentable, :polymorphic => true, :dependent => :destroy ... end class Article < ActiveRecord::Base has_many :comments, :as => :commentable, :dependent => :destroy ... end i have tried debug this issue like that user = User.first article = Article.first ability = Ability.new(user) ability.can?(:update, article) and i always get "= true" in ability check Note: user.role == author and article.user_id != user.id if you need more information please write thank's for your time && sorry for my english

• Regex expression is too greedy

  - by alastairs

  I'm writing a regular expression to match data from the IMDb soundtracks data file. My regexes are mostly working, although they are in places slurping too much text into my named groups. Take the following regex for example: "^ Performed by '?(?<performer>.*)('? \(qv\))?$" The performer group includes the string ' (qv) as well as the performer's name. Unfortunately, because the records are not consistently formatted, some performers' names are surrounded by single quotation marks whilst others are not. This means they are optional as far as the regex is concerned. I've tried marking the last group as a greedy group using the ?> group specifier, but this appeared to have no effect on the results. I can improve the results by changing the performer group to match a small range of characters, but this reduces my chances of parsing the name out correctly. Furthermore, if I were to just exclude the apostrophe character, I would then be unable to parse, e.g., band names containing apostrophes, such as Elia's Lonely Friends Band who performed Run For Your Life featured in Resident Evil: Apocalypse.

• Simplification / optimization of GPS track

  - by GreyCat

  I've got a GPS track, produces by gpxlogger(1) (supplied as a client for gpsd). GPS receiver updates its coordinates every 1 second, gpxlogger's logic is very simple, it writes down location (lat, lon, ele) and a timestamp (time) received from GPS every n seconds (n = 3 in my case). After writing down a several hours worth of track, gpxlogger saves several megabyte long GPX file that includes several thousands of points. Afterwards, I try to plot this track on a map and use it with OpenLayers. It works, but several thousands of points make using the map a sloppy and slow experience. I understand that having several thousands of points of suboptimal. There are myriads of points that can be deleted without losing almost anything: when there are several points making up roughly the straight line and we're moving with the same constant speed between them, we can just leave the first and the last point and throw anything else. I thought of using gpsbabel for such track simplification / optimization job, but, alas, it's simplification filter works only with routes, i.e. analyzing only geometrical shape of path, without timestamps (i.e. not checking that the speed was roughly constant). Is there some ready-made utility / library / algorithm available to optimize tracks? Or may be I'm missing some clever option with gpsbabel?

• Mysql partitioning: Partitions outside of date range is included

  - by Sturlum

  Hi, I have just tried to configure partitions based on date, but it seems that mysql still includes a partition with no relevant data. It will use the relevant partition but also include the oldest for some reason. Am I doing it wrong? The version is 5.1.44 (MyISAM) I first added a few partitions based on "day", which is of type "date" ALTER TABLE ptest PARTITION BY RANGE(TO_DAYS(day)) ( PARTITION p1 VALUES LESS THAN (TO_DAYS('2009-08-01')), PARTITION p2 VALUES LESS THAN (TO_DAYS('2009-11-01')), PARTITION p3 VALUES LESS THAN (TO_DAYS('2010-02-01')), PARTITION p4 VALUES LESS THAN (TO_DAYS('2010-05-01')) ); After a query, I find that it uses the "old" partition, that should not contain any relevant data. mysql> explain partitions select * from ptest where day between '2010-03-11' and '2010-03-12'; +----+-------------+------------+------------+-------+---------------+------+---------+------+------+-------------+ | id | select_type | table | partitions | type | possible_keys | key | key_len | ref | rows | Extra | +----+-------------+------------+------------+-------+---------------+------+---------+------+------+-------------+ | 1 | SIMPLE | ptest | p1,p4 | range | day | day | 3 | NULL | 79 | Using where | +----+-------------+------------+------------+-------+---------------+------+---------+------+------+-------------+ When I select a single day, it works: mysql> explain partitions select * from ptest where day = '2010-03-11'; +----+-------------+------------+------------+------+---------------+------+---------+-------+------+-------+ | id | select_type | table | partitions | type | possible_keys | key | key_len | ref | rows | Extra | +----+-------------+------------+------------+------+---------------+------+---------+-------+------+-------+ | 1 | SIMPLE | ptest | p4 | ref | day | day | 3 | const | 39 | | +----+-------------+------------+------------+------+---------------+------+---------+-------+------+-------+

• Silverlight 4: StackPanel doesn't resize, when content gets more narrow

  - by Aaginor

  I am using Silverlight 4 with Blend 4. I have a (horizontal) stackpanel that includes some TextBoxes and a Button. The stackpanel is set to stretch to the size that the content uses. The TextBoxes are on autosize too. When I add text to the Textboxes, the textbox size grows and the stackpanel grows too. So far so good. When I remove text from the textboxes, the textbox size shrinks (as excepted), but the stackpanel size doesn't. Is there any trick to make the stackpanel change size, when the content (textboxes) getting smaller? Thanks in advance, Frank Here is the XAML for the UserControl: <Grid x:Name="LayoutRoot"> <StackPanel x:Name="StackPanelBorder" Orientation="Horizontal"> <TextBox x:Name="TextBoxCharacteristicName" TextWrapping="Wrap" Text="Tex"> </TextBox> <TextBox x:Name="TextBoxSep" TextWrapping="Wrap" Text="=" IsReadOnly="True"> </TextBox> <Button x:Name="ButtonRemove" Content="-" Click="ButtonAddOrRemove_Click"> </Button> </StackPanel> </Grid>

• How to get a unique WindowRef in a dockable Qt application on Mac

  - by Robin

  How do I get a unique WindowRef from a Qt application that includes docked windows on the Mac? My code boils down to: int main(int argc, char* argv[]) { QApplication* qtApp = new QApplication(argc, argv); MyQMainWindow mainwin; mainwin.show(); } class MyQMainWindow : public QMainWindow { //... QDockWidget* mDock; MyQWidget* mDrawArea; QStackedWidget* mCentralStack; }; MyQMainWindow::MyQMainWindow() { mDock = new QDockWidget(tr("Docked Widget"), this); mDock->setMaximumWidth(180); //... addDockWidget(Qt::RightDockWidgetArea, mDock); mDrawArea = new MyQWidget(this); mCentralStack = new QStackedWidget(); mCentralStack->addWidget(mDrawArea); // Other widgets added to stack in production code. setCentralWidget(mCentralStack); //... } (Apologies if the above isn't syntactically correct, it's just easier to illustrate than to describe.) I added the following temporary code at the end of the above constructor: HIViewRef view1 = (HIViewRef) mDrawArea->winId(); HIViewRef view2 = (HIViewRef) mDock->winId(); WindowRef win1 = HIViewGetWindow(view1); WindowRef win2 = HIViewGetWindow(view2); My problem is that view1 and view2 are different, but win1 and win2 are the same! I tried the following equivalent on Windows: HWND win1 = (HWND)(mCentralDrawArea->winId()); HWND win2 = (HWND)(mDock1->winId()); This time win1 and win2 are different. I need the window handle to pass on to a 3rd party SDK so that it can draw into the central area only. BTW, I appreciate that the winId() method comes with lots of portability warnings, but a substantial refactor is out of the question for me. The same goes for using Carbon instead of Cocoa. Thanks.

• Why are Facebook Likes Insisting on using Wrong Product Image...?

  - by Joan Kent

  Firstly, I'm not a web developer so please be patient. I have read the other posts but I think i have everything covered. My website http://www.joaniesgifts.co.uk includes the like button on the product pages. However, I've found that certain product pages are using the incorrect image when a user likes the page. For example - http://www.joaniesgifts.co.uk/terramundi-money-pots/terramundi-money-pot-holiday-fund I think this may have been down to an original incorrect setup which is now corrected. However, the problem remains... The only thing I have to go on :- if i use the facebook url linter (developers.facebook.com/tools/debug) on the above product page, I receive the following error :- Object at URL 'http://www.joaniesgifts.co.uk/terramundi-money-pot-holiday-fund' of type '213689662010141:product' is invalid because the domain 'www.joaniesgifts.co.uk' is not allowed for the application id '213689662010141' which owns the specified object type. If you are the owner of this application, you can verify your configured 'Site Domain' at developers.facebook.com/apps/213689662010141. (I have verified my site's domain) Everything else appears fine except it is also showing the wrong image!! However, under Raw Open Graph Document Information it has the correct link! If I then click graph api - graph.facebook.com/10150450766583352 it again shows the wrong image was linked! I've no idea what else to do - can you help me? Kind Regards, Joan PS Graph API shows the incorrect image after a scrape only minutes ago { "url": "http://www.joaniesgifts.co.uk/terramundi-money-pot-holiday-fund", "type": "website", "title": "Terramundi Money Pot - Holiday Fund", "image": [ { "url": "http://www.joaniesgifts.co.uk/index.php?route=product\u00252Fproduct\u00252Fcaptcha" } ], "updated_time": "2011-11-11T18:54:38+0000", "id": "10150450766583352" }

  I try to give entity map on my entity app. But how can I do it? I try to make it like below: var test = ( from k in Kartlar where k.Rehber..... above codes k.(can not see Rehber or not working ) if you are correct , i can write k.Rehber.ID and others. i can not write: from k in Kartlar where k.Rehber.ID = 123 //assuming that navigation property name is Rehbar and its primary key of Rehbar table is ID && k.Kampanya.ID = 345 //assuming that navigation property name is Kampanya and its primary //key of Kampanya table is ID && k.Birim.ID = 567 //assuming that navigation property name is Birim and its primary key of Birim table is ID select k images you can see: also: You should look : http://i42.tinypic.com/2nqyyc6.png I have a table it includes 3 foreign key field like that: My Table: Kartlar ID (Pkey) RehberID (Fkey) KampanyaID (Fkey) BrimID (Fkey) Name Detail How can i write entity query with LINQ ? select * from Kartlar where RehberID=123 and KampanyaID=345 and BrimID=567 BUT please be careful I can not see RehberID, KampanyaID, BrimID in entity they are foreign key. I should use entity key but how?

• Fast, Unicode-capable, cross-platform programmer's text editor that shows invisibles like ZWSP?

  - by Roger_S

  Our publishing workflow includes Windows and Linux machines (there are some Macs too, but not in the critical-path workflow). Many texts include both English and Khmer and are marked-up in XML. XML Copy Editor is the best cross-platform open-source XML editor I've discovered. It utilizes the Scintilla editing component, which is generally good with Unicode but which does not enable non-printing or invisible characters like U+200B (zero-width space) and U+200C (zero-width non-joiner) to be displayed. Khmer does not separate words with a space character as Western languages do, so ZWSP is used in electronic texts to enable applications to break lines easily. Ideally I'd edit the markup and the content in a single editor, but XML awareness is less important at times than being able to display invisibles. (OpenOffice.org Writer and Microsoft Word are the only two apps I know that will display ZWSP. They are not suitable for the markup and text manipulations that need to be done to prepare manuscripts for publication, unfortunately, although I guess they're fine for authoring.) I tried out a promising editor last week, but a search-and-replace regex operation that took under a second in TextPad 4.7.3 lasted over twenty seconds. So I want to mention that speed and the ability to handle large (up to 150mb) files is also a concern. Is there a good, fast, free or not too expensive text editor, with versions on Windows and Linux and maybe mac too, Unicode-aware and capable of displaying invisibles like ZWSP? That has syntax highlighting, can handle large files and is customizable enough that I won't tear my hair out in frustration? Thanks, Roger_S

• error C2146: syntax error : missing ';' before identifier 'g_App'

• How can I use SQL to select duplicate records, along with counts of related items?

  - by mipadi

  I know the title of this question is a bit confusing, so bear with me. :) I have a (MySQL) database with a Person record. A Person also has a slug field. Unfortunately, slug fields are not unique. There are a number of duplicate records, i.e., the records have different IDs but the same first name, last name, and slug. A Person may also have 0 or more associated articles, blog entries, and podcast episodes. If that's confusing, here's a diagram of the structure: I would like to produce a list of records that match this criteria: duplicate records (i.e., same slug field) for people who also have at least 1 article, blog entry, or podcast episode. I have a SQL query that will list all records with the same slug fields: SELECT id, first_name, last_name, slug, COUNT(slug) AS person_records FROM people_person GROUP BY slug HAVING (COUNT(slug) > 1) ORDER BY last_name, first_name, id; But this includes records for people that may not have at least 1 article, blog entry, or podcast. Can I tweak this to fit the second criteria?

• Nullability (Regular Expressions)

  - by danportin

  In Brzozowski's "Derivatives of Regular Expressions" and elsewhere, the function d(R) returning ? if a R is nullable, and Ø otherwise, includes clauses such as the following: d(R1 + R2) = d(R1) + d(R2) d(R1 · R2) = d(R1) ? d(R2) Clearly, if both R1 and R2 are nullable then (R1 · R2) is nullable, and if either R1 or R2 is nullable then (R1 + R2) is nullable. It is unclear to me what the above clauses are supposed to mean, however. My first thought, mapping (+), (·), or the Boolean operations to regular sets is nonsensical, since in the base case, d(a) = Ø (for all a ? S) d(?) = ? d(Ø) = Ø and ? is not a set (nor is the return type of d, which is a regular expression). Furthermore, this mapping isn't indicated, and there is a separate notation for it. I understand nullability, but I'm lost on the definition of the sum, product, and Boolean operations in the definition of d: how are ? or Ø returned from d(R1) ? d(R2), for instance, in the definition off d(R1 · R2)?

• How slow are bit fields in C++

  - by Shane MacLaughlin

  I have a C++ application that includes a number of structures with manually controlled bit fields, something like #define FLAG1 0x0001 #define FLAG2 0x0002 #define FLAG3 0x0004 class MyClass { ' ' unsigned Flags; int IsFlag1Set() { return Flags & FLAG1; } void SetFlag1Set() { Flags |= FLAG1; } void ResetFlag1() { Flags &= 0xffffffff ^ FLAG1; } ' ' }; For obvious reasons I'd like to change this to use bit fields, something like class MyClass { ' ' struct Flags { unsigned Flag1:1; unsigned Flag2:1; unsigned Flag3:1; }; ' ' }; The one concern I have with making this switch is that I've come across a number of references on this site stating how slow bit fields are in C++. My assumption is that they are still faster than the manual code shown above, but is there any hard reference material covering the speed implications of using bit fields on various platforms, specifically 32bit and 64bit windows. The application deals with huge amounts of data in memory and must be both fast and memory efficient, which could well be why it was written this way in the first place.

• Is there a programmatic way to transform a sequence of image files into a PDF?

  - by Salim Fadhley

  I have a sequence of JPG images. Each of the scans is already cropped to the exact size of one page. They are sequential pages of a valuable and out of print book. The publishing application requires that these pages be submitted as a single PDF file. I could take each of these images and just past them into a word-processor (e.g. OpenOffice) - unfortunately the problem here is that it's a very big book and I've got quite a few of these books to get through. It would obviously be time-consuming. This is volunteer work! My second idea was to use LaTeX - I could make a very simple document that consists of nothing more than a series of in-line image includes. I'm sure that this approach could be made to work, it's just a little on the complex side for something which seems like a very simple job. It occurred to me that there must be a simpler way - so any suggestions? I'm on Ubuntu 9.10, my primary programming language is Python, but if the solution is super-simple I'd happily adopt any technology that works.

• How to deploy a single webapp with multiple web-modules that may be removed or added individually

  - by Daniel Bleisteiner

  We currently run two separate webapps (WARs) deployed in one single EAR containing additional JARs and settings. To improve our deployment I want to split one of these webapps into different modules that may be build and packaged individually. But I've currently no clue on how to package these modules so that I'm able to add or remove them as desired - at best during runtime. The webapp is getting more and more complex and I'd like to separate some of the functionality into modules. These modules should be packaged as single archives. As long as they contain only classes and resources loaded through code I know how to do this (simple JARs). But how about JSPs? Normally a WAR file contains JSPs or HTML files. I my case it are JSF pages utilizing JBoss Seam and RichFaces. These modules will add classes, resources and JSF pages and other includes to the running webapplication. Is it somehow possible to deploy them as individual archives to serve the same running webapp? We are using Maven for our build and packaging and deploy into JBoss v4.

• Is there an easier way to do Classic ASP "relative path"?

  - by Alex.Piechowski

  Right now, I'm having trouble. First of all I have a page, let's call it "http://blah.com/login". That obviously goes strait to "index.asp" A line of Main.asp: <!--#include file="resource/menu.asp"--> Page top includes all of what I need for my menu... so: Part of resource/menu.htm: <div id="colortab" class="ddcolortabs"> <ul> <li><a href="main.asp" title="Main" rel="dropmain"><span>Main</span></a></li> ... </ul> </div> <!--Main drop down menu --> <div id="dropmain" class="dropmenudiv_a"> <a href="main/announcements.asp">Announcements</a> <a href="main/contacts.asp">Contact Information</a> <a href="main/MeetingPlans.asp">Meeting Plan</a> <a href="main/photos.asp">Photo Gallery</a> <a href="main/events.asp">Upcoming Events</a> </div> Let's say I click on the "announcements" (http://blah.com/login/main/announcements.asp) link... Now I'm at the announcements page! But wait, I include the same menu file. Guess what happens: I get sent to "http://blah.com/login/main/main/announcements.asp Which doesn't exist... My solution: Make a menu_sub.asp include for any subpages. But wait a second... this WORKS, but it gets REALLY REALLY messy... What can I do to use just one main "menu.asp" instead of "menu_sub.asp"? using "/main/announcements.asp" WON'T be an option because this is a web application that will be on different directories per server. Any ideas? PLEASE

• Is it poor design to create objects that only execute code during the constructor?

  - by Curtix

  In my design I am using objects that evaluate a data record. The constructor is called with the data record and type of evaluation as parameters and then the constructor calls all of the object's code necessary to evaluate the record. This includes using the type of evaluation to find additional parameter-like data in a text file. There are in the neighborhood of 250 unique evaluation types that use the same or similar code and unique parameters coming from the text file. Some of these evaluations use different code so I benefit a lot from this model because I can use inheritance and polymorphism. Once the object is created there isn't any need to execute additional code on the object (at least for now) and it is used more like a struct; its kept on a list and 3 properties are used later. I think this design is the easiest to understand, code, and read. A logical alternative I guess would be using functions that return score structs, but you can't inherit from methods so it would make it kind of sloppy imo. I am using vb.net and these classes will be used in an asp.net web app as well as in a distributed app. thanks for your input

• Misplaced Layout after "home"-button and/or powersave screen

  - by TiGer

  Hi, I have an app which also includes a service with a Notification. Right now I am experiencing the foillowing problem : I start my app which will work fine after couple of minutes the powersave kicks in and I get a black screen I (or hte user) click the Menu-button to dismiss the black screen and to unlock the screenlock Now my (fullscreen) app will have "moved" like 30-40 pixels downwards, creating an ugly black border or hole. When I move the scrollwheel it will move up and down, and when I press the Menu button (showing my ap''s menu) it will "fix" the view... or I start my app which will work fine I press the Home button exiting the app, my service though will (correctly) keep running when selecting my service from the notification-bar I will get once again : -Now my (fullscreen) app will have "moved" like 30-40 pixels downwards, creating an ugly black border or hole. When I move the scrollwheel it will move up and down, and when I press the Menu button (showing my ap''s menu) it will "fix" the view... Any idea what the problem is ? The app is running on a ADP2 with Android 1.6 Thanks in advance ! Ok, after some testing I noticed that if I don't run the Activity on Fullscreen, but just leave the TtileBar away this won't happen... Still this is no solution to me, I want it to be fullscreen... Noticed siomething else, when I have the View with the black bar, and I press the home button it will "refresh" the View correctly just before actually going to the Home Screen :(

• Mulltiple configurations in Qt

  - by user360607

  Hi all! I'm new to Qt Creator and I have several questions regarding multiple build configurations. A side note: I have the QtCreator 1.3.1 installed on my Linux machine. I need to have two configurations in my Qt Creator project. The thing is that these aren't simply debug and release but are based on the target architecture - x86 or x64. I came across http://stackoverflow.com/questions/2259192/building-multiple-targets-in-qt-qmake and from that I went trying something like: Conf_x86 { TARGET = MyApp_x86 } Conf_x64 { TARGET = MyApp_x64 } This way however I don't seems to be able to use the Qt Creator IDE to build each of these separately (Build All, Rebuild All, etc. options from the IDE menu). Is there a way to achieve this - may be even show Conf_x86 and Conf_x64 as new build configurations in Qt Creator? One other thing the Qt I have is 64 bit so by default the target built using Qt Creator IDE will also be 64 bit. I noticed that the effective qmake call in the build step includes the following option '-spec linux-g++-64'. I also noticed that should I add '-spec linux-g++-32' in 'Additional arguments' it would override '-spec linux-g++-64' and the resulting target will be 32 bit. How can I achieve this by simply editing the contents of the .pro file? I saw that all these changes are initially saved in the .pro.user file but does doesn't suit me at all. I need to be able to make these configurations from the .pro file if possible. Any help will be appreciated. 10x in advance!

• In Mercurial, can I apply changes from one file to another file in the same branch?

  - by Stephen

  In the good old days of Subversion, I would sometimes derive a new file from an existing one using svn copy. Then if something changed in sections they had in common, I could still use svn merge to update the derived version. To use the example from hginit.com, say the "guac" recipe already exists, and I want to create a "superguac" that includes instructions on how to serve guacamole to 1000 raving soccer fans. Using the process I just described, I could: svn cp guac superguac svn ci -m "Created superguac by copying guac" (edit superguac) svn ci -m "Added instructions for serving 1000 raving soccer fans to superguac" (edit guac) svn ci -m "Fixed a typo in guac" svn merge -r3:4 guac superguac and thus the typo fix would be applied to superguac. Mercurial provides an hg copy command that marks a file as a copy of the original, but I'm not sure the repository structure supports a similar workflow. Here's the same example, and I carefully only edit a single file in the commit I want to use in the merge: hg cp guac superguac hg ci -m "Created superguac by copying guac" (edit superguac) hg ci -m "Added instructions for serving 1000 raving soccer fans to superguac" (edit guac) hg ci -m "Fixed a typo in guac" I now want to apply the change in guac to superguac. Is that possible? If so, what's the right command? Is there a different workflow in Mercurial that achieves the same results (limited to a single branch)?
