• Training new employees on undocumented code

  - by glowcoder

  Our company has a large codebase (2500+ classes/interfaces in just the core alone, many more in other projects) for our flagship software product. We've never really hired more than one developer at a time, so we don't have a real training process. We're going to be bringing in 2-5 more developers now, and probably more in the near future (to put things into perspective, we have 7 right now.) Obviously, we would like to get these guys up to speed as soon as possible. The catch - almost all of our classes (95%+) are completely undocumented. No javadoc, no design docs, basically completely undocumented. What strategies can we employ to bring the new developers up to speed? I'd like to consider situations that include the existing code getting documented, but it's possible management won't allow for the time to get that done, so I also must consider situations where that won't happen. Has anyone been there before? What worked well for you? Thanks!

• PHP Framework Benefits / Downfalls

  - by Lizard

  I have been a PHP developer for about 10 years now and until about a month ago I have never used a framework. The framework I am now using due to an existing codebase is cakePHP 1.2 I can see certain benefits of the frameworks with the basic helpers like default layouts. I can deffinately seen the benefits of MVC keeping the logic sperate etc. But the query building just seems to be bloated. Is this expected? Am I likely to be able to build better queries than the framework could build? I just feel I could get my apps running better without a framework. What are your thoughts?

• Git - Committing Machine Specific Configuration Files

  - by Gordon

  A common scenario when I develop is that the codebase will have several config files which require machine specific settings. These files will be checked into Git and other developers will always accidentally check them back in and break someone else's configuration. A simple solution to this would be to just not check them in to Git, or even to additionally add a .gitignore entry for them. However, I find that it is much more elegant to have some sensible defaults in the file which the developer can modify to suit his needs. Is there an elegant way to make Git play nicely with such files? I would like to be able to modify a machine-specific configuration file and then be able to run "git commit -a" without checking that file in.

• SBT equivalent of Ant target

  - by adelbertc

  What is the SBT equivalent (if any) of Ant targets? For example, a snippet in a build.xml file for Ant would be: <target name="runClient" description="run client"> <java classname="client.Client" fork="true"> <jvmarg value="-Djava.rmi.server.codebase=${client_web_codebase}"/> <jvmarg value="-Djava.security.policy=policy"/> <arg value="localhost"/> <classpath> <pathelement location="dist/client.jar"/> </classpath> </java> </target> And then I would do something like ant runClient to launch the application "client.Client" with the jvmargs specified in the XML.. is there an SBT equivalent, or a way for SBT to hook into Ant to do this?

• How to programmatically fetch posts matching a search query in WordPress?

  - by Alan Bellows

  In my plugin code I would like to perform a WP_Query (or similar) which returns all posts matching a given query string, as if the user typed that same string into the WordPress search form. Perhaps I'm just being dense, but I cannot seem to find a way to do so. I would expect to have a special parameter for WP_Query, such as matching, but I see no evidence of one. I'll start going through the WordPress codebase to see how it's done internally, and I'll post the answer here if I find it. I just thought someone might happen to know offhand.

• Continuous integration with multiple branch development

  - by ryanprayogo

  In the project that I'm working on, we are using SVN with 'Stable Trunk' strategy. What that means is that for each bug that is found, QA opens a bug ticket and assigns it to a developer. Then, a developer fixes that bug and checks it in a branch (off trunk, let's call this the bug branch) and that branch will only contain fixes for that particular bug ticket When we decided to do a release, for each bug fixes that we want to release to the customer, a developer will merge all the fixes from several bug branch to trunk and proceed with the normal QA cycle. The problem is that we use trunk as the codebase for our CI job (Hudson, specifically), and therefore, for all commits to the bug branch, it will miss the daily build until it gets merged to trunk when we decided to release the new version of the software. Obviously, that defeats the purpose of having CI. What is the proper way to fix this issue?

• Android/Eclipse: Creating multiple builds with different com identifiers.

  - by Dave

  Hi, I have an app that requires two builds - one is a demo app, the other uses the same codebase but uses a flag to introduce different functionality. The identifier must be different each time (e.g. com.siteA.appA and com.siteB.appB). However it doesn't appear to be trivial to use the refactor functionality in Eclipse to change the com identifier - all references change apart from the "import com.siteA.appA.R" reference. Is there a way to create different builds with different com identifiers/app name within Eclipse? Thanks

• Do I need to change the package name for the free version of my app?

  - by teedyay

  I have an application that I'm going to publish to the Android market. I'm planning on releasing a paid-for version and a free version with restricted feature set. During development I've ensured I can turn features on and off by setting a few constant values, so I only have one codebase. However, now I come to release I'm not clear if I need to make a copy of the app with a different package name for the free version. The documentation on how the market works say updates will only be recognised if they have the same package name and are signed with the same key. Does this mean it's OK to release two applications with the same package name but signed with different keys, or will this break something? Or is it just bad practice?

• Are there any lint tools for C and C++ that check formatting?

  - by Nathan Fellman

  I have a codebase that is touched by many people. While most people make an effort to keep the code nicely formatted (e.g. consistent indentation and use of braces), some don't, and even those that do can't always do it because we all use different editors, so settings like spaces vs. tabs are different. Is there any standard lint tool that checks that code is properly formatted, but doesn't actually change it (like indent but that returns only errors and warnings)? While this question could be answered generally, my focus is on C and C++, because that's what this project is written in.

• Simple rails routing / url question

  - by justinbach

  I'm using Ryan Bates' nifty authentication in my application for user signup and login. Each user has_many :widgets, but I'd like to allow users to browse other users' widgets. I'm thinking that a url scheme like /username/widgets/widget_id would make a lot of sense--it would keep all widget-related code in the same place (the widgets controller). However, I'm not sure how to use this style of URL in my app. Right now my codebase is such that it permits logged-in users to browse only their own widgets, which live at /widgets/widget_id. What changes would I need to make to routes.rb, my models classes, and any place where links to a given widget are needed? I've done Rails work before but am a newb when it comes to more complicated routing, etc, so I'd appreciate any feedback. Thanks for your consideration!

• A tool to determine jar dependencies based on existing code?

  - by geoffeg

  Is there a tool that can determine .jar dependencies given a directory of .jar files and a separate directory of java source code? I need to generate Eclipse .classpath files based on an existing code base that doesn't have any dependencies defined. To be more specific, I've been given a large codebase consisting of a dozen or so J2EE-style projects and a single directory of jar files. My client uses a custom development and build framework that is just too arcane for me to use and get any real work done. The projects do not have any information about their dependencies, either between projects or to jar libraries. I would expect this tool would have to spin through each jar file, indexing the classes available in that file and then go through each file in the project source code tree and match up the dependencies, possibly writing out a .classpath file with the required jar files. I realize this is a rather simplistic view of the operation, as duplicate classes among the jar files and such might make things more difficult.

• Should I Split Tables Relevant to X Module Into Different DB? Mysql

  - by Michael Robinson

  I've inherited a rather large and somewhat messy codebase, and have been tasked with making it faster, less noodly and generally better. Currently we use one big database to hold all data for all aspects of the site. As we need to plan for significant growth in the future, I'm considering splitting tables relevant to specific sections of the site into different databases, so if/when one gets too large for one server I can more easily migrate some user data to different mysql servers while retaining overall integrity. I would still need to use joins on some tables across the new databases. Is this a normal thing to do? Would I incur a performance hit because of this?

• Does declaring many identical anonymous classes waste memory in java?

  - by depsypher

  I recently ran across the following snippet in an existing codebase I'm working on and added the comment you see there. I know this particular piece of code can be rewritten to be cleaner, but I just wonder if my analysis is correct. Will java create a new class declaration and store it in perm gen space for every call of this method, or will it know to reuse an existing declaration? protected List<Object> extractParams(HibernateObjectColumn column, String stringVal) { // FIXME: could be creating a *lot* of anonymous classes which wastes perm-gen space right? return new ArrayList<Object>() { { add(""); } }; }

• Hibernate entities stored as HttpSession attribute values

  - by njudge

  I'm dealing with a legacy Java application with a large, fairly messy codebase. There's a fairly standard 'User' object that gets stored in the HttpSession between requests, so the servlets do stuff like this at the top: HttpSession session = request.getSession(true); User user = (User)session.getAttribute("User"); The old user authentication layer (which I won't describe; suffice to say, it did not use a database) is being replaced with code mapped to the DB with Hibernate. So 'User' is now a Hibernate entity. My understanding of Hibernate object life cycles is a little fuzzy, but it seems like storing 'User' in the HttpSession now becomes a problem, because it will be retrieved in a different transaction during the next request. What is the right thing to be doing here? Can I just use the Hibernate Session object's update() method to reattach the User instance the next time around? Do I need to?

• how to access jquery internal data?

  - by Unknown

  As you may or may not be aware as of jQuery 1.7 the whole event system was rewritten from the ground up. The codebase is much faster and with the new .on() method there is a lot of uniformity to wiring up event handlers. One used to be able to access the internal events data and investiate what events are registered on any given element, but recently this internal information has been hidden based on the following scenario... It seems that the "private" data is ALWAYS stored on the .data(jQuery.expando) - For "objects" where the deletion of the object should also delete its caches this makes some sense. In the realm of nodes however, I think we should store these "private" members in a separate (private) cache so that they don't pollute the object returned by $.fn.data()" Although I agree with the above change to hide the internal data, I have found having access to this information can be helpful for debugging and unit testing. What was the new way of getting the internal jquery event object in jQuery 1.7?

• Co-opt popular abandonware opensource project?

  - by Mike Bouck

  Here's the scenario: A popular open source project is used/loved by many but has become stale due to the fact that the last drop came out nearly a year ago. Many bugs/feature requests/fixes have been logged in the interim and everyone is getting by via downloading the trunk and building custom/private builds with the changes incorporated. The copyright is simple -- there is none and the code is in the public domain. The project owner spins the project as community open source and has set up a sourceforge site, but to date (5 years running now) has yet to accept one contributor. In other words the "community" is a community of one. The project owner takes great pride in the project and has obviously contributed a lot of time/effort but for whatever reason has has seemingly abandoned the project and is unresponsive when offers of help are made. So, the question, should the community fork the codebase, set up a new community site, and take matters in their own hands?

• How can I embed a flash movie in a zend view programmatically?

  - by curro

  I have tried to embed a flash movie in a zend view using the htmlFlash helper. In theory you only have to pass the movie path to the htmlFlash helper in a phtml view: echo $this-htmlFlash('/path/to/myMovie.swf'); And the framework will generate the html code in the html page: <object data="/path/to/flash.swf" type="application/x-shockwave-flash" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab"> </object> However, I have done so and the code doesn't appear on the source code. Has anyone had this problem? Thank you

• Resources for Win32 C/C++ programming

  - by EricM

  I have experience in a variety of languages (Java, Perl, C#, PHP, javascript, ansi-C for microprocessors, Objective-C and others), with Win32 programming not being an area I've done a lot of work in. Now part of my job entails maintaining a large Win32 codebase that stretches back 15 years and includes everything from C written originally for Win95 to MFC to COM to 64-bit code for Win7 to C++ using Boost and so on. If there's a variation on how to do something it's in there. Are there any good Win32 C/C++ references that discuss both the proper way to do things today and give you a little sense of how things evolved? Something like this discussion of all the various boolean types, or how to approach the API monstrosity of simply copying a string. I don't see my career heading too far down this path, but I do like to understand what I'm working with and I think this is an important part of programming history. thanks, Eric

• Fast comparison of char arrays?

  - by StackedCrooked

  I'm currently working in a codebase where IPv4 addresses are represented as pointers to u_int8. The equality operator is implemented like this: bool Ipv4Address::operator==(const u_int8 * inAddress) const { return (*(u_int32*) this->myBytes == *(u_int32*) inAddress); } This is probably the fasted solution, but it causes the GCC compiler warning: ipv4address.cpp:65: warning: dereferencing type-punned pointer will break strict-aliasing rules How can I rewrite the comparison correctly without breaking strict-aliasing rules and without losing performance points? I have considered using either memcmp or this macro: #define IS_EQUAL(a, b) \ (a[0] == b[0] && a[1] == b[1] && a[2] == b[2] && a[3] == b[3]) I'm thinking that the macro is the fastest solution. What do you recommend?

• is there a good reason to fear closed-source code *inside* of open-source libraries?

  - by jcollum

  Here's the situation. At work here, I hear there is resistance to using open source code (Nant in particular) because there might be copyrighted code in there. Meaning somewhere in that open source tool or library there might be a chunk of code that was directly lifted from copyrighted code. In theory, this means our company (which is quite large) get sued for big money because they used an open source library. We don't ship any software, so how this theoretical plaintiff would find this out is a mystery. I have also heard that some group of people came through a year or two ago and actually found instances of this in our codebase. That's hearsay of course, so who knows. Is this simple paranoia? Didn't something similar to this happen with Linux a while ago? Wouldn't the burden of checking for copyrighted code lie with the people who made the code, not the people who use it?

• variables in batch scripts

  - by richzilla

  I'm trying to set up a batch file to automatically deploy a php app to a web server. Basically, what I want is an entirely automated process: I would just give it a revision number from the repository and it would then export the files, upload via ftp and then update deployment info at the repo host (codebase). However, I'm starting from scratch here. How would I set up a batch file to accept a variable when it was run? For example, the command myfile.bat /revision 42 should deploy revision 42 to my server. If anyone can point me in the right direction I'd appreciate it.
