  • Memory leak in chrome.extension.sendRequest()

    - by jprim
    Chrome Version : 9.0.597.19 (Build 68937) beta & current stable I have simplified my code as far as possible. I ended up with the attached extension: content.js (content script run on every site): setInterval(function() { chrome.extension.sendRequest({ }, function(response) { //Do nothing }); }, 1); background.js (background page script): chrome.extension.onRequest.addListener(function(request, sender, sendResponse) { sendResponse({ }); }); When you install this extension, you can observe it eating up memory extremely fast (I got 90MB in 1 min with 9 tabs opened). You can speed up the process by opening more tabs. Of course, the extension I am actually developing does not send requests every millisecond, but only every 3 seconds. This just slows it down, though. A user who has run it in the background for a long time with many tabs opened has reported 100MB of memory usage, and I can reproduce it to a less extreme extent, too.

  • memcpy() safety on adjacent memory regions

    - by JaredC
    I recently asked a question on using volatile and was directed to read some very informative articles from Intel and others discussing memory barriers and their uses. After reading these articles I have become quite paranoid though. I have a 64-bit machine. Is it safe to memcpy into adjacent, non-overlapping regions of memory from multiple threads? For example, say I have a buffer: char buff[10]; Is it always safe for one thread to memcpy into the first 5 bytes while a second thread copies into the last 5 bytes? My gut reaction (and some simple tests) indicate that this is completely safe, but I have been unable to find documentation anywhere that can completely convince me.

  • zeroing out memory

    - by robUK
    Hello, gcc 4.4.4 c89 I am just wondering what most c programmers do when they want to zero out memory. For example I have a buffer of 1024 bytes. Sometimes I do this: char buffer[1024] = {0}; Which will zero all bytes. However, should I declare like this and use memset? char buffer[1024]; . . memset(buffer, 0, sizeof(buffer); Is there any real reason you have to zero the memory? What is the worst that can happen by not doing it? Many thanks for any suggestions,

  • In-memory data structure that supports boolean querying

    - by sanity
    I need to store data in memory where I map one or more key strings to an object, as follows: "green", "blue" -> object1 "red", "yellow" -> object2 I need to be able to efficiently receive a list of objects, where the strings match some boolean criteria, such as: ("red" OR "green") AND NOT "blue" I'm working in Java, so the ideal solution would be an off-the-shelf Java library. I am, however, willing to implement something from scratch if necessary. Anyone have any ideas? I'd rather avoid the overhead of an in-memory database if possible, I'm hoping for something comparable in speed to a HashMap (or at least the same order of magnitude).

  • memory access violation error - 0xC0000005

    - by nobody
    I got memory access violation error sometimes.... but I don't know where the error comes from... So I reviewed the code and I found some strange code... delete m_p1; A *a = new A(); a->b = *c; m_p1 = a; --> strange code. I think it's a little strange line.... can i use the m_p1 after delete the m_p1? It can make some memory access error??

  • About memory and delete object in c++

    - by barssala
    I will give some examples and explain. First, I declare some object like CString* param = new CString[100] And when I declare this one, my memory would increase a little bit because it's some implemented string. Then I store this object in some list of CString just like List<CString> myList = new List<CString>; // new list of CString myList.add(param); This is my question: I wanna know, when I delete myList, my param isn't deleted, right? And memory in param still exists. Do I misunderstand?

  • dynamic memory allocation [closed]

    - by gcc
    i wanna write a program that creates (allocating memory) and manipulates (adding elements and increasing memory etc.) integer arrays dynamically according to given input sequences. input sequence which starts with the maximum number of arrays, includes integers to be put into arrays and some one letter characters which are commands to carry out some tasks (activating next array, deleting an array etc). also, i wanna create *c_arrays which is the address of the array whose elements are the actual capacities (How many integer slots are already allocated for an array?) of arrays how should i organize(set up) the algorithm?

  • removing image tag from memory

    - by Chapsterj
    I have seen some code to check if a background image on a div is loaded. What they are doing is adding a img tag to memory but storing it in a variable and using that to see if the image is loaded with the load event. My question is does the $img tag stay in memory and how would I be able to remove that tag when the load event has been called. var $div = $('div'), bg = $div.css('background-image'); if (bg) { var src = bg.replace(/(^url\()|(\)$|[\"\'])/g, ''), $img = $('<img>').attr('src', src).on('load', function() { // do something, maybe: $div.fadeIn(); }); } }); I got this code above from this post

  • memory management question -- releasing an object which has to be returned

    - by ulag
    Hi, I have an NSMutableArray called playlist. This is in a method called getAllPlaylists. The code is something like this: -(NSMutableArray *)getAllPlaylists { //playlist is an instance variable playlist = [[NSMutableArray alloc] init]; //memory leak here . . //some code here which populates the playlist array [playlist addObject: object1]; . . return playlist; } The array allocation step of playlist is causing a memory leak. In such a scenario where can i release this array? Or can i avoid allocation n initialization of playlist here by doing something else?

  • 4GB of RAM in MacOSX 10.5, only 3GB in MacOSX 10.6

    - by Albert
    Hi, I was using MacOSX 10.5 on my MacBook until today and I had 4GB of memory there. Now I have updated to MacOSX 10.6 and it only displays 3GB. Why is that? How can I fix it? Also, I am a bit wondering why most people (well, most of the Google hits explained the 3GB issue that way -- leaving out the fact that it has worked earlier) are saying that a 32bit system can under no circumstances access more than 3.2GB. Don't we have PAE nowadays in most systems? Thanks, Albert

  • Backquote on iPhone keyboard

    - by lc
    Is there a backquote (backtick) on the iPhone keyboard, and if so, where is it? When I'm writing a post here or on any of the sister sites (especially SO), I want to use the backquote for inline code blocks. Under the single quote key, I've found two curly/angled quotes, but those (’ and ‘) don't seem to do the trick...

  • Bank Interleave Requested but not enabled

    - by wbeard52
    I have a ECS A770M-A motherboard with a 2.2GHz Phenom 64 Quad Core processor with 4 gigs of ram. I also have a 1GB DDR3 Zotac GeForce 9500GT video card installed in the computer. I believe the main memory is DDR2. The problem I am having is that I get a "Bank Interleave Requested but not Enabled" error on startup. The computer boots up fine (no error) with the 4gigs of ram if I replace the video card with the previous 256MB video card. I have also tried placing a single gig of ram in the computer with the Zotac video card and still get the error. My question is what would typically cause this error and would a DDR3 video ram be compatible with DDR2 system ram? Thanks

  • Why does Windows 7 always automatically change the input or keyboard language?

    - by B-Ball
    I am wondering why Windows 7 always automatically changes my input or keyboard language. I've a notebook with an integrated QWERTY keyboard English (United States). Traveling, I use that one but, additionally, I've my own as well as a much better keyboard at home which is a QWERTZ keyboard German (Germany). Thus, being at home, I'd like to use my QWERTZ keyboard. Unfortunately, Windows 7 does not play along at this one. Every time, I start up my notebook, it is usually set to English (United States) but that's not the problem. In case, I'd use my notebook QWERTY keyboard English (United States), that's fine. However, if I start up my notebook and I'd like to use my QWERTZ keyboard German (Germany), I usually press ALT + Left Shift in order to switch from English (United States) to German (Germany) and Windows 7 switches the input language but only for the program that is currently open. If my input language is set to German (Germany) and I, e.g., open NotePad, Windows 7 automatically switches my input language to English (United States). This is very annoying since I've to change the input or keyboard language to German (Germany) every time I open up a new program. Why doesn't Windows 7 stay with one input language if I changed it manually by pressing ALT + Left Shift? Why doesn't the manual change of the input or keyboard language apply for the whole Windows 7? Why does it only affect the currently opened program? Since I've two keyboards with two different layouts, I seriously need to have both of the keyboards languages installed. I tried both of the below settings in order to find a solution for my problem. Currently, I am using the first option, two input languages. First option: Two input language - www.abload.de/img/19aie.jpg Second option: Two keyboard languages - www.abload.de/img/2nb4x.jpg Thank you very much in advance.

  • ECC RAM in GA-G33M-DS2R? Or any Gigabyte/G33M motherboard?

    - by Gregory Hoerner
    I'm looking to retire a server which has 12GB of ECC DDR2 RAM. I'd like to upgrade my multi-purpose machine (firewall, file server, VM host for Windows Home Server, etc.) using the RAM from the server. I was just wondering: Has anyone had experience using ECC RAM in a GA-G33M-DS2R motherboard (or any Gigabyte GA-G33M-XXXX motherboard for that matter)? Has anyone had experience using ECC RAM in a motherboard with a G33M chipset. I've searched everywhere and found the attitude positive of ECC memory working in a Non-ECC board, but I would like some specific positive feedback before proceeding tonight. I have to kick the entire house offline, which I don't like to do without good reason :)

  • NX Client running on OS X 10.6.3 => NX Server Ubuntu 10.04: weird keymapping issue

    - by Mike D
    I have been using Ubuntu 9.10 at work after switching from vista. After being (expectedly) disappointed with performance over VNC (via VPN) when logging in from home, I came across the NOMACHINE suite. Last week, I upgraded from OS X 10.6.2 = 10.6.3 at home. After that, I also updated my NX Client at home to the latest version, as there were issues with recent changes in the OSX X11 setup that rendered the NX connection useless. At that point, everything worked fine. Fast forward, I upgraded from 9.10 = 10.04 on my work machine the next day, and after coming home and trying to log-in remotely, I noticed that the "s" and "m" keys, when pressed locally, acted as if the meta key was being pressed on the remote machine. That is, the "s" key opens in the Ubuntu login menu (the power icon), and the "m" key opens the messaging menu. I found some info on using xmodmap to remap keys, however, I can't even begin to fathom what keys I could remap to solve this issue. Any ideas?

  • Turn off the Linux OOM killer by default?

    - by Peter Eisentraut
    The OOM killer on Linux wreaks havoc with various applications every so often, and it appears that not much is really done on the kernel development side to improve this. Would it not be better, as a best practice when setting up a new server, to reverse the default on the memory overcommitting, that is, turn it off (vm.overcommit_memory=2) unless you know you want it on for your particular use? And what would those use cases be where you know you want the overcommitting on? As a bonus, since the behavior in case of vm.overcommit_memory=2 depends on vm.overcommit_ratio and swap space, what would be a good rule of thumb for sizing the latter two so that this whole setup keeps working reasonably?

  • Vim: Show the index of tabs in the tabline

    - by bitmask
    Lets say I opened file1.txt, file2.txt, file3a.txt and file3b.txt such that the tabline (the thing on the top) looks like this: file1.txt file2.txt 2 file3a.txt (Note how file3b.txt. is missing because it is shown in a split, in the same tab as file3a.txt) To move more quickly between tabs (with <Number>gt), I would like each tab to display its index, along the filename. Like so: 1:<file1.txt> 2:<file2.txt> 3:<2 file3a.txt> The formatting (the angle braces in particular) are optional; I just want the index to appear there (the 1:, 2: and so on). No clues on :h tab-page-commands or google whatsoever.

  • .inputrc settings: delete-char and [] keybindings not working

    - by tanascius
    Hello, I am using mingw under windows. When I am using ruby (irb) my 'special' characters like []{} and \ are not working. This is because of my german keyboard, where these keys are used together with AltGr (Alt + Ctrl). I found a solution for this here or here. Now, when I add the line "\M-[": "[" to my .inputrc file the delete-key no longer works. It is defined as usual: "\e[3~": delete-char Pressing delete just returns [3, while Ctrl + v, delete returns ^[[3~ as expected. Somehow these two definitions in .inputrc do not work together. Any ideas? EDIT: It is only the delete key that is not working, my other bindings all work, like: "\e[1~": beginning-of-line # home (ok) "\e[2~": paste-from-clipboard # insert (ok) "\e[3~": delete-char # delete (PROBLEM) "\e[4~": end-of-line # end (ok) "\e[5~": history-search-backward # pageup (ok) "\e[6~": history-search-forward # pagedown (ok)
