  • .net File.Copy very slow when copying many small files (not over network)

    - by Guavaman
    I'm making a simple folder sync backup tool for myself and ran into quite a roadblock using File.Copy. Doing tests copying a folder of ~44,000 small files (Windows mail folders) to another drive in my system, I found that using File.Copy was over 3x slower than using a command line and running xcopy to copy the same files/folders. My C# version takes over 16+ minutes to copy the files, whereas xcopy takes only 5 minutes. I've tried searching for help on this topic, but all I find is people complaining about slow file copying of large files over a network. This is neither a large file problem nor a network copying problem. I found an interesting article about a better File.Copy replacement, but the code as posted has some errors which causes problems with the stack and I am nowhere near knowledgeable enough to fix the problems in his code. Are there any common or easy ways to replace File.Copy with something more speedy?

  • Java: design problem with final-value and empty constructor

  • C# ArrayList calling on a constructor class

    - by EvanRyan
    I'm aware that an ArrayList is probably not the way to go with this particular situation, but humor me and help me lose this headache. I have a constructor class like follows: class Peoples { public string LastName; public string FirstName; public Peoples(string lastName, string firstName) { LastName = lastName; FirstName = firstName; } } And I'm trying to build an ArrayList to build a collection by calling on this constructor. However, I can't seem to find a way to build the ArrayList properly when I use this constructor. I have figured it out with an Array, but not an ArrayList. I have been messing with this to try to build my ArrayList: ArrayList people = new ArrayList(); people[0] = new Peoples("Bar", "Foo"); people[1] = new Peoples("Quirk", "Baz"); people[2] = new Peopls("Get", "Gad"); My indexing is apparently out of range according to the exception I get.

  • Spring overloaded constructor injection

    - by noob
    This is the code : public class Triangle { private String color; private int height; public Triangle(String color,int height){ this.color = color; this.height = height; } public Triangle(int height ,String color){ this.color = color; this.height = height; } public void draw() { System.out.println("Triangle is drawn , + "color:"+color+" ,height:"+height); } } The Spring config-file is : <bean id="triangle" class="org.tester.Triangle"> <constructor-arg value="20" /> <constructor-arg value="10" /> </bean> Is there any specific rule to determine which constructor will be called by Spring ?

  • c++ Using const in a copy constructor?

    - by Anton
    I have never written copy constructor, so in order to avoid pain i wanted to know if what i have coded is legit. It compiles but i am not sure that it works as a copy constructor should. Also do i have to use const in the copy constructor or i can simply drop it. (What i dont like about const is that the compiler cries if i use some non const functions). //EditNode.h class EditNode { explicit EditNode(QString elementName); EditNode(const EditNode &src); } //EditNodeContainer.h class EditNodeContainer : public EditNode { explicit EditNodeContainer(QString elementName); EditNodeContainer(const EditNodeContainer &src); } //EditNodeContainer.cpp EditNodeContainer::EditNodeContainer(QString elementName):EditNode(elementName) { } //This seems to compile but not sure if it works EditNodeContainer::EditNodeContainer(const EditNodeContainer &src):EditNode(src) { } //the idea whould be to do something like this EditNodeContainer *container1 = new EditNodeContainer("c1"); EditNodeContainer *copyContainer = new EditNodeContainer(container1);

  • C++ method chaining including class constructor

    - by jena
    Hello, I'm trying to implement method chaining in C++, which turns out to be quite easy if the constructor call of a class is a separate statement, e.g: Foo foo; foo.bar().baz(); But as soon as the constructor call becomes part of the method chain, the compiler complains about expecting ";" in place of "." immediately after the constructor call: Foo foo().bar().baz(); I'm wondering now if this is actually possible in C++. Here is my test class: class Foo { public: Foo() { } Foo& bar() { return *this; } Foo& baz() { return *this; } }; I also found an example for "fluent interfaces" in C++ (http://en.wikipedia.org/wiki/Fluent_interface#C.2B.2B) which seems to be exactly what I'm searching for. However, I get the same compiler error for that code. Thanks in advance for any hint. Best, Jean

  • Constructor return value

    - by Ivan Gromov
    Could you tell me what is wrong with my class constructor? Code: CVector::CVector (int size_) { if (size_ > 0) { this->size = size_; this->data = new double[size]; for (int i = 0; i < size; i++) { (*this)(i) = i; } } cout << "constructor end" << endl; return; } Usage example: tvector = CVector(6); I get an access violation after "constructor end" output.

  • Why Java cannot find my constructor?

    - by Roman
    Well, maybe it is a stupid question, but I cannot resolve this problem. In my ServiceBrowser class I have this line: ServiceResolver serviceResolver = new ServiceResolver(ifIndex, serviceName, regType, domain); And compiler complains about it. It says: cannot find symbol symbol : constructor ServiceResolver(int,java.lang.String,java.lang.String,java.lang.String) This is strange, because I do have a constructor in the ServiceResolver: public void ServiceResolver(int ifIndex, String serviceName, String regType, String domain) { this.ifIndex = ifIndex; this.serviceName = serviceName; this.regType = regType; this.domain = domain; } ADDED: I removed void from the constructor and it works! Why?

  • variadic constructors

    - by FredOverflow
    Are variadic constructors supposed to hide the implicitly generated ones, i.e. the default constructor and the copy constructor? struct Foo { template<typename... Args> Foo(Args&&... x) { std::cout << "inside the variadic constructor\n"; } }; int main() { Foo a; Foo b(a); } Somehow I was expecting this to print nothing after reading this answer, but it prints inside the variadic constructor twice on g++ 4.5.0 :( Is this behavior correct?

  • How to copy path on a mac?

    - by AngryHacker
    Windows refugee here. On Windows you can easily copy the path and paste it elsewhere to get to the directory. Here is the situation on the Mac. I am in the Finder 20 folders down and I see the file I want. I go to my application and want to open it, so I pick Open Document from the File menu. However, it is exceedingly difficult and time-consuming to get to the place I want. Is there a way to copy the path in the finder and paste it in the File Open dialog of my application?

  • Command-line sort and copy text files to one single file renders an error

    - by user169997
    I stumbled on question 217394 which explains how to copy files sorted alphabetically into one single file. Trying to implement the command myself rendered the following error message: The system cannot find the file specified. The command I am trying to run is here: for /f %i in ('dir /a-d /o-n /b O:\OrdersExport\Order*.txt') do @type %i C:\Users\Admin\Documents\OrderImport.txt The error does not appear if I browsed to the folder in question first: C:\O: C:\cd OrdersImport I simply want one line to copy from destination to that single file. By the way, if it matters, O: is a mapped folder over network

  • Is there a way to create a copy-on-write copy of a directory?

    - by BCS
    I'm thinking of a situation where I would have something that creates a copy of a directory, tweaks a few files, and then does some processing on the result. This wold be done fairly often, maybe a few dozen times a day. (The exact use case is testing patch submissions; dupe the code, patch it, build/test/report/etc.) What I'm looking for could be done by creating a new directory structure and populating it with hard links from the origonal. However this only works if all the tools you use delete and recreate files rather than edit them in place. Is there a way to have the file system do copy-on-write for a file? Note: I'm aware that many FSs use COW at a block level (all updates are done via writes to new blocks) but this is not what I want.

  • esxi 5.1 - copy paste host config doesn't work?

    - by w--
    I followed these instructions for esxi 5.1 to enable copy paste from the host config. (search for "To enable this option for all the virtual machines in the ESX/ESXi host:") http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1026437 But copy and paste doesn't work for new VMs or existing VMs. Did I do something wrong somewhere? I've rebooted VMs and even rebooted host. I can confirm that if I do a per VM configuration, it works. Just not a central host config. Here is a screenshot of my /etc/vmware/config file

  • Copy a file from source directory to target base directory and maintain source path

    - by Citizen Dos
    Forgive me, I am probably not using the right terms to describe the problem and misunderstanding the most basic usage for a couple of common commands. I have a simple find statement that is locating files that I want to copy. I want to tack on the -exec cp {} and have cp copy the file from the source directory to a new base directory, but include the full path. For example: "find . -name *.txt" locates /user/username/projects/source.txt "cp {} [now what?]" copies the file to /user/newuser/projects/source.txt

  • Large file copy from NFS to local disk performance drop

    - by Bernhard
    I'm trying to copy a 200GB file from an NFS mount to a local disk. The local disk is an XFS filesystem on a LVM on top of a RAID 5 system (hardware RAID controler). I'm using rsync to monitor the transfer speed. At the beginning the IO speed is about 200MB/s, stable for the first 18GB. But then the performance drops by a factor of 10-20 and never recovers to the initial rate. Sometimes it reaches about 50-100MB/s but just for a few seconds and then the process seems to hang for a bit. At the same time all file-stat operations on the target filesystem are blocking for a long time (minutes). Also interrupting the copy process blocks for several minutes, a sub-sequent delete of the partly copied file takes also several minutes. Any ideas what could be causing this?

  • Copy & Paste Images Wiki functionality?

    - by Jakub
    I was discussing this with some coworkers, they would like a wiki, but are turned off by the need to constantly [browse] and [upload] files. They like the functionality of Lotus Notes that they can copy & paste screenshots (or crops etc) directly into Notes databases / libraries. But they are not fans of Lotus notes behond that (performance, etc,) Anyone work with a free (open source hopefully) wiki of documenting application that just allows copy & paste of text & image content? Would be great to have one internally installed that we could use for documentation without constantly uploading/attaching files. Not sure if I am asking for functionality that is not available in a browser.

  • Recursively copy only new or changed files

    - by Niklas
    I'm sure this must have been asked and answered before, but I just can't find it right now... I have a Visual Studio post-build action that currently does a recursive copy (using xcopy) of an output folder to a different folder. This takes longer than I like and I'd like to only copy newly created and newer (changed) files each time (which xcopy doesn't seem to support). I cannot depend on any not-installed-by-default tool since the solution is used by different developers on different machines. What would a superuser do?

  • How to copy and paste code with retaining the format

    - by Sab
    This question may have been asked before but I was unable to find any solution. So here goes: When I browse and see some code that I would like to copy I simply use ctrl+c and ctrl+v. Most of the time this works fine. But in some cases (websites like stackoverflow and others ) when I copy the code and paste it , it only comes on one line in eclipse. I have tried pasting this code into eclipse and select all and hitting auto format but this doesnt help either. I have also pasted the code into komodo and word. But to no avail. The code simply refuses to align itself. Does anyone know any solution to this?

  • Reliable file copy (move) process - mostly Unix/Linux

    - by mfinni
    Short story : We have a need for a rock-solid reliable file mover process. We have source directories that are often being written to that we need to move files from. The files come in pairs - a big binary, and a small XML index. We get a CTL file that defines these file bundles. There is a process that operates on the files once they are in the destination directory; that gets rid of them when it's done. Would rsync do the best job, or do we need to get more complex? Long story as follows : We have multiple sources to pull from : one set of directories are on a Windows machine (that does have Cygwin and an SSH daemon), and a whole pile of directories are on a set of SFTP servers (Most of these are also Windows.) Our destinations are a list of directories on AIX servers. We used to use a very reliable Perl script on the Windows/Cygwin machine when it was our only source. However, we're working on getting rid of that machine, and there are other sources now, the SFTP servers, that we cannot presently run our own scripts on. For security reasons, we can't run the copy jobs on our AIX servers - they have no access to the source servers. We currently have a homegrown Java program on a Linux machine that uses SFTP to pull from the various new SFTP source directories, copies to a local tmp directory, verifies that everything is present, then copies that to the AIX machines, and then deletes the files from the source. However, we're finding any number of bugs or poorly-handled error checking. None of us are Java experts, so fixing/improving this may be difficult. Concerns for us are: With a remote source (SFTP), will rsync leave alone any file still being written? Some of these files are large. From reading the docs, it seems like rysnc will be very good about not removing the source until the destination is reliably written. Does anyone have experience confirming or disproving this? Additional info We will be concerned about the ingestion process that operates on the files once they are in the destination directory. We don't want it operating on files while we are in the process of copying them; it waits until the small XML index file is present. Our current copy job are supposed to copy the XML file last. Sometimes the network has problems, sometimes the SFTP source servers crap out on us. Sometimes we typo the config files and a destination directory doesn't exist. We never want to lose a file due to this sort of error. We need good logs If you were presented with this, would you just script up some rsync? Or would you build or buy a tool, and if so, what would it be (or what technologies would it use?) I (and others on my team) are decent with Perl.
