  • The Stub Proto: Not Just For Stub Objects Anymore

    - by user9154181
    One of the great pleasures of programming is to invent something for a narrow purpose, and then to realize that it is a general solution to a broader problem. In hindsight, these things seem perfectly natural and obvious. The stub proto area used to build the core Solaris consolidation has turned out to be one of those things. As discussed in an earlier article, the stub proto area was invented as part of the effort to use stub objects to build the core ON consolidation. Its purpose was merely as a place to hold stub objects. However, we keep finding other uses for it. It turns out that the stub proto should be more properly thought of as an auxiliary place to put things that we would like to put into the proto to help us build the product, but which we do not wish to package or deliver to the end user. Stub objects are one example, but private lint libraries, header files, archives, and relocatable objects, are all examples of things that might profitably go into the stub proto. Without a stub proto, these items were handled in a variety of ad hoc ways: If one part of the workspace needed private header files, libraries, or other such items, it might modify its Makefile to reach up and over to the place in the workspace where those things live and use them from there. There are several problems with this: Each component invents its own approach, meaning that programmers maintaining the system have to invest extra effort to understand what things mean. In the past, this has created makefile ghettos in which only the person who wrote the makefiles feels confident to modify them, while everyone else ignores them. This causes many difficulties and benefits no one. These interdependencies are not obvious to the make, utility, and can lead to races. They are not obvious to the human reader, who may therefore not realize that they exist, and break them. Our policy in ON is not to deliver files into the proto unless those files are intended to be packaged and delivered to the end user. However, sometimes non-shipping files were copied into the proto anyway, causing a different set of problems: It requires a long list of exceptions to silence our normal unused proto item error checking. In the past, we have accidentally shipped files that we did not intend to deliver to the end user. Mixing cruft with valuable items makes it hard to discern which is which. The stub proto area offers a convenient and robust solution. Files needed to build the workspace that are not delivered to the end user can instead be installed into the stub proto. No special exceptions or custom make rules are needed, and the intent is always clear. We are already accessing some private lint libraries and compilation symlinks in this manner. Ultimately, I'd like to see all of the files in the proto that have a packaging exception delivered to the stub proto instead, and for the elimination of all existing special case makefile rules. This would include shared objects, header files, and lint libraries. I don't expect this to happen overnight — it will be a long term case by case project, but the overall trend is clear. The Stub Proto, -z assert_deflib, And The End Of Accidental System Object Linking We recently used the stub proto to solve an annoying build issue that goes back to the earliest days of Solaris: How to ensure that we're linking to the OS bits we're building instead of to those from the running system. The Solaris product is made up of objects and files from a number of different consolidations, each of which is built separately from the others from an independent code base called a gate. The core Solaris OS consolidation is ON, which stands for "Operating System and Networking". You will frequently also see ON called the OSnet. There are consolidations for X11 graphics, the desktop environment, open source utilities, compilers and development tools, and many others. The collection of consolidations that make up Solaris is known as the "Wad Of Stuff", usually referred to simply as the WOS. None of these consolidations is self contained. Even the core ON consolidation has some dependencies on libraries that come from other consolidations. The build server used to build the OSnet must be running a relatively recent version of Solaris, which means that its objects will be very similar to the new ones being built. However, it is necessarily true that the build system objects will always be a little behind, and that incompatible differences may exist. The objects built by the OSnet link to other objects. Some of these dependencies come from the OSnet, while others come from other consolidations. The objects from other consolidations are provided by the standard library directories on the build system (/lib, /usr/lib). The objects from the OSnet itself are supposed to come from the proto areas in the workspace, and not from the build server. In order to achieve this, we make use of the -L command line option to the link-editor. The link-editor finds dependencies by looking in the directories specified by the caller using the -L command line option. If the desired dependency is not found in one of these locations, ld will then fall back to looking at the default locations (/lib, /usr/lib). In order to use OSnet objects from the workspace instead of the system, while still accessing non-OSnet objects from the system, our Makefiles set -L link-editor options that point at the workspace proto areas. In general, this works well and dependencies are found in the right places. However, there have always been failures: Building objects in the wrong order might mean that an OSnet dependency hasn't been built before an object that needs it. If so, the dependency will not be seen in the proto, and the link-editor will silently fall back to the one on the build server. Errors in the makefiles can wipe out the -L options that our top level makefiles establish to cause ld to look at the workspace proto first. In this case, all objects will be found on the build server. These failures were rarely if ever caught. As I mentioned earlier, the objects on the build server are generally quite close to the objects built in the workspace. If they offer compatible linking interfaces, then the objects that link to them will behave properly, and no issue will ever be seen. However, if they do not offer compatible linking interfaces, the failure modes can be puzzling and hard to pin down. Either way, there won't be a compile-time warning or error. The advent of the stub proto eliminated the first type of failure. With stub objects, there is no dependency ordering, and the necessary stub object dependency will always be in place for any OSnet object that needs it. However, makefile errors do still occur, and so, the second form of error was still possible. While working on the stub object project, we realized that the stub proto was also the key to solving the second form of failure caused by makefile errors: Due to the way we set the -L options to point at our workspace proto areas, any valid object from the OSnet should be found via a path specified by -L, and not from the default locations (/lib, /usr/lib). Any OSnet object found via the default locations means that we've linked to the build server, which is an error we'd like to catch. Non-OSnet objects don't exist in the proto areas, and so are found via the default paths. However, if we were to create a symlink in the stub proto pointing at each non-OSnet dependency that we require, then the non-OSnet objects would also be found via the paths specified by -L, and not from the link-editor defaults. Given the above, we should not find any dependency objects from the link-editor defaults. Any dependency found via the link-editor defaults means that we have a Makefile error, and that we are linking to the build server inappropriately. All we need to make use of this fact is a linker option to produce a warning when it happens. Although warnings are nice, we in the OSnet have a zero tolerance policy for build noise. The -z fatal-warnings option that was recently introduced with -z guidance can be used to turn the warnings into fatal build errors, forcing the programmer to fix them. This was too easy to resist. I integrated 7021198 ld option to warn when link accesses a library via default path PSARC/2011/068 ld -z assert-deflib option into snv_161 (February 2011), shortly after the stub proto was introduced into ON. This putback introduced the -z assert-deflib option to the link-editor: -z assert-deflib=[libname] Enables warning messages for libraries specified with the -l command line option that are found by examining the default search paths provided by the link-editor. If a libname value is provided, the default library warning feature is enabled, and the specified library is added to a list of libraries for which no warnings will be issued. Multiple -z assert-deflib options can be specified in order to specify multiple libraries for which warnings should not be issued. The libname value should be the name of the library file, as found by the link-editor, without any path components. For example, the following enables default library warnings, and excludes the standard C library. ld ... -z assert-deflib=libc.so ... -z assert-deflib is a specialized option, primarily of interest in build environments where multiple objects with the same name exist and tight control over the library used is required. If is not intended for general use. Note that the definition of -z assert-deflib allows for exceptions to be specified as arguments to the option. In general, the idea of using a symlink from the stub proto is superior because it does not clutter up the link command with a long list of objects. When building the OSnet, we usually use the plain from of -z deflib, and make symlinks for the non-OSnet dependencies. The exception to this are dependencies supplied by the compiler itself, which are usually found at whatever arbitrary location the compiler happens to be installed at. To handle these special cases, the command line version works better. Following the integration of the link-editor change, I made use of -z assert-deflib in OSnet builds with 7021896 Prevent OSnet from accidentally linking to build system which integrated into snv_162 (March 2011). Turning on -z assert-deflib exposed between 10 and 20 existing errors in our Makefiles, which were all fixed in the same putback. The errors we found in our Makefiles underscore how difficult they can be prevent without an automatic system in place to catch them. Conclusions The stub proto is proving to be a generally useful construct for ON builds that goes beyond serving as a place to hold stub objects. Although invented to hold stub objects, it has already allowed us to simplify a number of previously difficult situations in our makefiles and builds. I expect that we'll find uses for it beyond those described here as we go forward.

  • DV-AVI in DivX Plus Player and VirtualDub - playback issue

    - by user714965
    I have an AVI-video which I had (digitally) transferred from a DV camera to my PC. The video contains errors at the beginning most likely because the DV tape was pretty old. When playing this video in the DivX Plus Player I get some picture artefacts and some high noise peaks of the sound. These stops after two seconds. When I'm playing this video in VirtualDub (where I want to cut it) I get the same picture artefacts. But the sound errors (those loud high peaks) lasts ten seconds. These sound errors are also contained in the cutted video. Why does the video have more errors when played in VirtualDub? I think because of different codecs which are used for decoding the video? How can I change the codec which VirtualDub uses for decoding? I have installed ffdshow for this but it seems that it is not used because I don't get the ffdshow icon in the taskbar when playing the video in VirtualDub. When playing in DivX Player Plus I get this icon.

  • Is it OK to use images of GPL'd code in a CC 3.0 BY video?

    - by marcusw
    I am making a video in which I would like to use pictures of some Linux Kernel code. I am looking to release the finished product under the CC 3.0 BY license, but the Kernel is released under the GPL, which would not allow this if the code is in text format. However, since it will be in low-resolution, incredibly incomplete, non-usable, non-compilable, non-editable (at least without lots of finagling) format, would this constitute fair use or find another loophole to slip through? Thanks for the help, I will understand if this is considered off topic.

  • How to play an MKV 3D side-by-side video?

    - by djechelon
    I have a video in Matroska format (MKV, file extension .mkv), 3D half-SBS, where the 1280x720 frame shows the left-eye frame on the left and the right-eye frame on the right. I don't have a 3DTV, but I have NVidia 3D Vision: I tried to open it with PowerDVD 10 with no result (program hangs). With the same PowerDVD, I tried to play the Avatar 3D trailer downloaded from YouTube (MP4 format), but it now shows it the two frames. PowerDVD 10 is advertised to support 3D and 3D Vision. Why can't I play these videos? NVidia Stereoscopic player plays the Avatar trailer fine, but it doesn't support MKV.

  • Is there a way to make AutoGK to resize the video?

    - by Jian Lin
    AutoGK is so far a good tool for converting video clips in DVD-R disc into .avi to post to YouTube. But I captured some Wii game play, and it is 16 : 9 ratio, but AutoGK only output the .avi in 4 : 3 ratio. Is there actually a way to tweak it to output the avi as 16 : 9? Otherwise, I need to run VirtualDub and download DivX codec to run it again to resize it 16 : 9. Any way this is done, or any other recommendations? thanks for helping.

  • How to batch convert video files on OSX for AppleTV2 / iPhone4?

    - by Luke404
    I'd like to have a solution to batch convert video files to a format suitable for the AppleTV2, iPad2, iPhone4, while at the same time preserving as much quality as possible; I want a single output file that will play on both devices and also good for consumption by other Mac software (eg. Aperture, iMovie, iTunes). Batch processing is a requirement since I'm gonna convert many many files from different sources (mainly lots of videos captured by compact digital cameras, cell phones, and so on). I'm looking into ffmpeg and MEncoder (both installed via MacPorts), but I can't seem to find a suitable preset for libx264 even if everyone out there is talking about them. A different approach involving different software would be ok too as long as I can script it somehow and run it on a whole directory full of files to be converted.

  • How to make a video card use DVI output by default in text mode?

    - by Igor Zinov'yev
    I have an ASUS ENGT440/DI1GD5 video card which has three outputs: DVI, D-Sub and HDMI. I am using both D-Sub and DVI, but my main monitor is connected to the DVI output. Everything works fine except for the text mode. The card somehow uses the D-Sub output in text mode when both monitors are connected (when I disconnect the D-Sub output and leave only the primary monitor connected to the DVI output, it's being used correctly). How do I make the card use only the DVI output (or both) in text mode?

  • Can you use a DVI-VGA Adapter on a monitor instead of a video card?

    - by Joel Coehoorn
    I suspect the answer to this is "no", but here goes: I have a monitor with inputs for DVI and VGA. I want to be able to share this display with two computers (one at a time, of course) that both have VGA only. I also have a DVI-VGA dongle that came with a video card that's in a different computer. Can I connect this dongle directly to the DVI port on the monitor so that I can connect both VGA computers? I'd rather not resort to a kvm.

  • Looking for a video media player program that saves colour/volume profiles for individual videos?

    - by verve
    I use VLC right now but I'm tired of having 24 VLC players open because I watch that many different things each week so I just leave them open indefinitely; having to set each one up with the different colour/brightness/volume when the computer crashes is time-consuming. Also, having those many players open gets crazy. Is a good video media player available that lets you create or save profiles for videos watched or going to watched such as colour/brightness/volume?

    I've ordered a Hauppauge WinTV-HVR 900 HD video/tv capture unit.

The latter has an HDMI output which works perfectly with my LG 42" LCD TV, enabling display of BBC iPlayer and other catchup services. Will the live or recorded HD signal from the WinTV-HVR 900 HD connected to the laptop's USB input be output on the laptop's HDMI socket as HD? Come to that, will SD content be output? The reason I ask is that I had a problem with a Pinnacle unit which displayed OK on the laptop's screen but not on the TV screen (which did display all the normal Windows material). I've tried the Hauppage website, but it doesn't even acknowledge the existence of the WinTV-HVR 900 HD!

  • In Eclipse RCP, how do I disable a save toolbar button according to the "dirty" property in editor

    - by paulgreg
    In my eclipse RCP 3.3 application, I would like to enable or disable a 'save' toolbar button according to current editor dirty flag. I'm trying to use the <enabledWhen tag but I can't make it work. Here's the portion of code in plugin.xml : <command commandId="org.acme.command.save" icon="icons/save.png" id="org.acme.command.save" style="push"> <enabledWhen> <instanceof value="activeEditor"/> <test property="dirty" value="true"/> </enabledWhen> </command> Do you have any idea how that is supposed to work ?

  • What is a robust jQuery Rich Text Editor with image upload capabilities?

    - by thinkswan
    I know this question has been asked countless times, but answers are mixed, so I thought I'd test the waters and see what the latest verdict is out in the development community. I need a [preferably jQuery] rich text editor plugin that simply attaches itself to <textarea> elements and supports image uploads. It doesn't need to be too advanced. Just alignment, bold, italic, styles and image support. I tried CKEditor (along with CKFinder for image uploads), but it just has too many features and is too heavy for what I need. This is going to be used for simple webpage editing.

  • What is the best XPS WYSIWYG Editor that will output XAML?

    - by Simon
    I am looking for a WYSIWYG for XPS that will ouput the raw XAML. My intentions is use the tool for a way to quickly generate and test the XAML (of XPS documents) with the intention of then generating the same xaml in code and programmatically generating an XPS document. The same approach that many people use for generating html. Can anyone recommend any of the below products or suggest any others? Better yet does anyone know of a free XPS editor? NiXPS Edit $300USD http://www.nixps.com/nixps_edit_20.html XamlPad is free but also quite limited and does not really target XPS. Office System Power Tools is not WYSIWYG http://blogs.msdn.com/adrianford/archive/2008/07/03/visual-studio-and-xps-files.aspx XPS eXaminer 1.0 $399USD http://storefront.qualitylogic.com/p-16-qualitylogic-xps-examiner.aspx

  • How can I put my own text hover into default Eclipse editor?

    - by vitivy
    I need to put some extra information into to the standard "javadoc" hover, that shows up when you go with mouse over some token. Or I need to create a new hover showing that information while pressing some key (like alt) and then hovering (I can see that this is done e.g. with the shift key, which enables us to see the hover with sourcecode, instead of javadoc). So far I found documentation on how to create hover in your own editors, but I need to extend the default java editor. Basically I am interested in showing some e-mail information related to the classname (token) over which user is hovering. Is there any extension point that could be used for this? Thanks for any help!

  • Visual Studio web tests: Can a coded webtest be run through the Web Test Editor run view?

    - by Frank Rosario
    Hello, Full disclosure, I'm new to Visual Studio Web Tests and coding for them. I've written a webtest; coded in VB; it runs great. Our QA engineer wants to use this script for performance testing; but he wants the nice GUI that comes when you build a WebTest with the VS WebTest Editor and run it. Is there a way to run a coded webtest through this view? He wants to be able to view each test as it runs to see which pages are having issues, but within the GUI he's used to. Alternatively, I know I could just code something that writes out to a log file; but before I go with that solution; I just wanted to see if this is possible. Any constructive input is greatly appreciated.

  • Looking for a lean WYSIWYG inline editor for CMS projects that includes an image upload feature?

    - by Roeland
    Hey guys, I am looking to find a lean WYSIWYG inline editor. The main required feature is image uploading. A simple way to upload an image to the server and use it in the content being editted. I have come across a whole bunch of editors but nothing I liked so far. I am looking for something open source and free. So far I have checked out TinyMCE which is free.. untill you need image uploading capabilities. Ckeditor looks great.. uses jquery.. but requires you to have your own server side script to upload images. They barely give any documentation on how to do this. There were a few others, but the bottom line was that I cant find anything that is simple with out of the box image uploading capabilities. Thanks for any advice you may give!

  • Images from url to listview

    - by Andres
    I have a listview which I show video results from YouTube. Everything works fine but one thing I noticed is that the way it works seems to be a bit slow and it might be due to my code. Are there any suggestions on how I can make this better? Maybe loading the images directly from the url instead of using a webclient? I am adding the listview items in a loop from video feeds returned from a query using the YouTube API. The piece of code which I think is slowing it down is this: Feed<Video> videoFeed = request.Get<Video>(query); int i = 0; foreach (Video entry in videoFeed.Entries) { string[] info = printVideoEntry(entry).Split(','); WebClient wc = new WebClient(); wc.DownloadFile(@"http://img.youtube.com/vi/" + info[0].ToString() + "/hqdefault.jpg", info[0].ToString() + ".jpg"); string[] row1 = { "", info[0].ToString(), info[1].ToString() }; ListViewItem item = new ListViewItem(row1, i); YoutubeList.Items.Add(item); imageListSmall.Images.Add(Bitmap.FromFile(info[0].ToString() + @".jpg")); imageListLarge.Images.Add(Bitmap.FromFile(info[0].ToString() + @".jpg")); } public static string printVideoEntry(Video video) { return video.VideoId + "," + video.Title; } As you can see I use a Webclient which downloads the images so then I can use them as image in my listview. It works but what I'm concerned about is speed..any suggestions? maybe a different control all together?

  • How to disable Eclipse's behavior of maximizing editor when double clicking a tab?

    - by Steve Kehlet
    I recently updated my Eclipse (now running 20100218-1602), and I've found whenever I click around quickly between tabs on the tab bar, it will sometimes maximize the editor and hide the PHP Explorer to the left. After researching a little, this appears to be a feature of double clicking a tab. So I guess it's my fault, I'm sure I'm clicking around too fast and mistakenly double clicking a tab, but it happens often enough on what I'd consider a normal editing session that I've come to absolutely loathe it, and even after the usual googling due diligence cannot figure out how to turn it off. From this post (http://stackoverflow.com/questions/594659/eclipses-tab-double-click-on-visual-studio) someone mentions the Window.AutoHideAll shortcut, however that seems to only be for assigning keyboard shortcuts--this is a mouse click thing. But maybe it's a clue. I can't find anything relevant under Eclipse - Preferences - PHP. I don't think it's specific to PHP because if I switch to the Java perspective, double clicking a tab hides the Package Explorer. Any suggestions are appreciated, thanks!
