  • How to resolve java.nio.charset.UnmappableCharacterException in Scala 2.8.0?

    - by Roman Kagan
    I'm using Scala 2.8.0 and trying to read pipe delimited file like in code snipped below: object Main { def main(args: Array[String]) :Unit = { if (args.length > 0) { val lines = scala.io.Source.fromPath("QUICK!LRU-2009-11-15.psv") for (line <-lines) print(line) } } } Here's the error: Exception in thread "main" java.nio.charset.UnmappableCharacterException: Input length = 1 at java.nio.charset.CoderResult.throwException(CoderResult.java:261) at sun.nio.cs.StreamDecoder.implRead(StreamDecoder.java:319) at sun.nio.cs.StreamDecoder.read(StreamDecoder.java:158) at java.io.InputStreamReader.read(InputStreamReader.java:167) at java.io.BufferedReader.fill(BufferedReader.java:136) at java.io.BufferedReader.read(BufferedReader.java:157) at scala.io.BufferedSource$$anonfun$1$$anonfun$apply$1.apply(BufferedSource.scala:29) at scala.io.BufferedSource$$anonfun$1$$anonfun$apply$1.apply(BufferedSource.scala:29) at scala.io.Codec.wrap(Codec.scala:65) at scala.io.BufferedSource$$anonfun$1.apply(BufferedSource.scala:29) at scala.io.BufferedSource$$anonfun$1.apply(BufferedSource.scala:29) at scala.collection.Iterator$$anon$14.next(Iterator.scala:149) at scala.collection.Iterator$$anon$2.next(Iterator.scala:745) at scala.collection.Iterator$$anon$2.head(Iterator.scala:732) at scala.collection.Iterator$$anon$24.hasNext(Iterator.scala:405) at scala.collection.Iterator$$anon$20.hasNext(Iterator.scala:320) at scala.io.Source.hasNext(Source.scala:209) at scala.collection.Iterator$class.foreach(Iterator.scala:534) at scala.io.Source.foreach(Source.scala:143) ... at infillreports.Main$.main(Main.scala:8) at infillreports.Main.main(Main.scala) Java Result: 1

  • ValidationException class version mismatch

    - by suszterpatt
    I have a simple EJB application that I can deploy and test on a local WebLogic instance (v10.3.0.0) without problems. I need to deploy this on a remote WL server (v10.3.3.0), and test it from a local machine. Deployment is successful, but when I try to run any of the clients from JDeveloper, I get this error: <2010.06.02. 16:08:36 CEST> <Error> <RJVM> <BEA-000503> <Incoming message header or abbreviation processing failed java.io.InvalidClassException: org.eclipse.persistence.exceptions.ValidationException; local class incompatible: stream classdesc serialVersionUID = 3793659634176227230, local class serialVersionUID = -7605463488982202416 java.io.InvalidClassException: org.eclipse.persistence.exceptions.ValidationException; local class incompatible: stream classdesc serialVersionUID = 3793659634176227230, local class serialVersionUID = -7605463488982202416 at java.io.ObjectStreamClass.initNonProxy(ObjectStreamClass.java:562) at java.io.ObjectInputStream.readNonProxyDesc(ObjectInputStream.java:1583) at java.io.ObjectInputStream.readClassDesc(ObjectInputStream.java:1496) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1316) at java.io.ObjectInputStream.readObject(ObjectInputStream.java:351) at weblogic.rjvm.ClassTableEntry.readExternal(ClassTableEntry.java:36) at java.io.ObjectInputStream.readExternalData(ObjectInputStream.java:1792) at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1751) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1329) at java.io.ObjectInputStream.readObject(ObjectInputStream.java:351) at weblogic.rjvm.InboundMsgAbbrev.readObject(InboundMsgAbbrev.java:65) at weblogic.rjvm.InboundMsgAbbrev.read(InboundMsgAbbrev.java:37) at weblogic.rjvm.MsgAbbrevJVMConnection.readMsgAbbrevs(MsgAbbrevJVMConnection.java:227) at weblogic.rjvm.MsgAbbrevInputStream.init(MsgAbbrevInputStream.java:173) at weblogic.rjvm.MsgAbbrevJVMConnection.dispatch(MsgAbbrevJVMConnection.java:439) at weblogic.rjvm.t3.MuxableSocketT3.dispatch(MuxableSocketT3.java:322) at weblogic.socket.AbstractMuxableSocket.dispatch(AbstractMuxableSocket.java:394) at weblogic.socket.SocketMuxer.readReadySocketOnce(SocketMuxer.java:917) at weblogic.socket.SocketMuxer.readReadySocket(SocketMuxer.java:849) at weblogic.socket.JavaSocketMuxer.processSockets(JavaSocketMuxer.java:283) at weblogic.socket.SocketReaderRequest.run(SocketReaderRequest.java:29) at weblogic.work.ExecuteRequestAdapter.execute(ExecuteRequestAdapter.java:21) at weblogic.kernel.ExecuteThread.execute(ExecuteThread.java:145) at weblogic.kernel.ExecuteThread.run(ExecuteThread.java:117) Can anyone explain why I'm getting this error, and what I can do to resolve it?

  • Passing System classes as constructor parameters

    - by mcl
    This is probably crazy. I want to take the idea of Dependency Injection to extremes. I have isolated all System.IO-related behavior into a single class so that I can mock that class in my other classes and thereby relieve my larger suite of unit tests of the burden of worrying about the actual file system. But the File IO class I end up with can only be tested with integration tests, which-- of course-- introduces complexity I don't really want to deal with when all I really want to do is make sure my FileIO class calls the correct System.IO stuff. I don't need to integration test System.IO. My FileIO class is doing more than simply wrapping System.IO functions, every now and then it does contain some logic (maybe this is the problem?). So what I'd like is to be able to test my File IO class to ensure that it makes the correct system calls by mocking the System.IO classes themselves. Ideally this would be as easy as having a constructor like so: public FileIO( System.IO.Directory directory, System.IO.File file, System.IO.FileStream fileStream ) { this.Directory = directory; this.File = file; this.FileStream = fileStream; } And then calling in methods like: public GetFilesInFolder(string folderPath) { return this.Directory.GetFiles(folderPath) } But this doesn't fly since the System.IO classes in question are static classes. As far as I can tell they can neither be instantiated in this way or subclassed for the purposes of mocking.

  • Linux disk IO load breakdown, by filesystem path and/or process?

    - by Ryan B. Lynch
    Does anyone have experience with a tool that can provide an indication of disk IO load by filesystem path. I use to 'iostat' utility, frequently, to learn how much disk activity is taking place on a Linux host. 'iostat' provides a per-device breakdown, so you can see activity on a particular block device. But it doesn't go any deeper than that--you can't, for instance, query the write load generated by 'httpd' in the directory '/var/log/httpd/'.

  • How to use IO.popen to write-to and read-from a child process?

    - by mackenir
    I am running net share from a ruby script to delete a windows network share. If files on the share are in use, net share will ask the user if they want to go ahead with the deletion, so my script needs to inspect the output from the command, and write out Y if it detects that net share is asking it for input. In order to be able to write out to the process I open it with access flags "r+". When attempting to write to the process with IO#puts, I get an error: Errno::EPIPE: Broken pipe What am I doing wrong here? (The error occurs on the line net_share.puts "Y") (The question text written out by net share is not followed by a newline, so I am using IO#readpartial to read in the output.) def delete_network_share share_path command = "net share #{share_path} /DELETE" net_share = IO.popen(command, "r+") text = "" while true begin line = net_share.readpartial 1000 #read all the input that's available rescue EOFError break end text += line if text.scan("Do you want to continue this operation? (Y/N)").size > 0 net_share.puts "Y" net_share.flush #probably not needed? end end net_share.close end

  • Can tomcat perform ssl redirection by filtering host alias?

    - by Stephen
    Hi, We have a tomcat server (6.0.20) running one web application behind two urls, e.g. www.foo and secure.foo This is configured in the server.xml as one host with a single alias: <Host name="www.foo" appBase="webapps"> <Context docBase="foo" path=""></Context> <Alias>secure.foo</Alias> </Host> Ideally we'd like any requests to secure.foo on port 80 to be automatically redirected to use ssl. However, I can only find instructions for redirecting based on the path after the hostname, so I could add a /* security constraint but then this would apply to both urls. Does anyone know if it's possible to apply the redirection by filtering on hostname requested? (We've already got the ssl connector, certificate, etc. working ok). I know we could do it by sticking an apache server in front of tomcat and handling the redirection there, but I'm curious to know if tomcat can do this on its own. Thanks

  • unexplainable packet drops with 5 ethernet NICs and low traffic on Ubuntu

    - by jon
    I'm stuck on problem where my machine started to drops packets with no sign of ANY system load or high interrupt usage after an upgrade to Ubuntu 12.04. My server is a network monitoring sensor, running Ubuntu LTS 12.04, it passively collects packets from 5 interfaces doing network intrusion type stuff. Before the upgrade I managed to collect 200+GB of packets a day while writing them to disk with around 0% packet loss depending on the day with the help of CPU affinity and NIC IRQ to CPU bindings. Now I lose a great deal of packets with none of my applications running and at very low PPS rate which a modern workstation NIC would have no trouble with. Specs: x64 Xeon 4 cores 3.2 Ghz 16 GB RAM NICs: 5 Intel Pro NICs using the e1000 driver (NAPI). [1] eth0 and eth1 are integrated NICs (in the motherboard) There are 2 other PCI-X network cards, each with 2 Ethernet ports. 3 of the interfaces are running at Gigabit Ethernet, the others are not because they're attached to hubs. Specs: [2] http://support.dell.com/support/edocs/systems/pe2850/en/ug/t1390aa.htm uptime 17:36:00 up 1:43, 2 users, load average: 0.00, 0.01, 0.05 # uname -a Linux nms 3.2.0-29-generic #46-Ubuntu SMP Fri Jul 27 17:03:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux I also have the CPU governor set to performance mode and irqbalance off. The problem still occurs with them on. # lspci -t -vv -[0000:00]-+-00.0 Intel Corporation E7520 Memory Controller Hub +-02.0-[01-03]--+-00.0-[02]----0e.0 Dell PowerEdge Expandable RAID controller 4 | \-00.2-[03]-- +-04.0-[04]-- +-05.0-[05-07]--+-00.0-[06]----07.0 Intel Corporation 82541GI Gigabit Ethernet Controller | \-00.2-[07]----08.0 Intel Corporation 82541GI Gigabit Ethernet Controller +-06.0-[08-0a]--+-00.0-[09]--+-04.0 Intel Corporation 82546EB Gigabit Ethernet Controller (Copper) | | \-04.1 Intel Corporation 82546EB Gigabit Ethernet Controller (Copper) | \-00.2-[0a]--+-02.0 Digium, Inc.

On the old system, if it couldn't keep up this is where the drops would be. I drop packets on multiple interfaces just about every second, usually in small increments of 2-4. I tried all these sysctl values, I'm currently using the uncommented ones. # cat /etc/sysctl.conf # high net.core.netdev_max_backlog = 3000000 net.core.rmem_max = 16000000 net.core.rmem_default = 8000000 # defaults #net.core.netdev_max_backlog = 1000 #net.core.rmem_max = 131071 #net.core.rmem_default = 163480 # moderate #net.core.netdev_max_backlog = 10000 #net.core.rmem_max = 33554432 #net.core.rmem_default = 33554432 Here's an example of an interface stats report with ethtool.

With and without, it's the same. This is what my interrupt stats looked like before the upgrade, after, with ACPI on PCI it showed multiple NICs bound to an interrupt and shared with other devices such as USB drives which I didn't like so I think i'm going to keep it with ACPI off as it's easier to designate sole purpose interrupts.

I can't figure out why my PCI-X slots are negotiated as PCI. The network cards are all PCI-X with the exception of the integrated NICs that came with the server. In the output below it looks as if eth3 and eth2 negotiated at PCI-X speeds rather than PCI:66Mhz. Wouldn't they all drop to PCI:66Mhz? If your integrated NICs are PCI, as labeled below (eth0,eth1), then wouldn't all devices on your bus speed drop down to that slower bus speed? If not, I still don't know why only one of my NICs ( each has two ethernet ports) is labeled as PCI-X in the output below. Does that mean it is running at PCI-X speeds are is it showing that it's capable? # dmesg | grep e1000 [ 3678.349337] e1000: Intel(R) PRO/1000 Network Driver - version 7.3.21-k8-NAPI [ 3678.349342] e1000: Copyright (c) 1999-2006 Intel Corporation.

  • Using thread inter-communication to increase my server app's IO throughput; not sure how

    - by Howard Guo
    My server application creates a new thread for each incoming connection. Incoming requests are serialized in a BlockingQueue. There is one worker thread taking items from the queue, produce a response and send the response through socket. I have noticed a throughput issue: Currently, worker thread is responsible of sending the response message through socket, thus severely wasting processing power and throughput. I am considering: rather than sending the response itself, why not telling network IO threads to send the response? However, when I think about thread inter-communication, I cannot yet figure out how to approach it: Worker thread will produce a response, but how will it inform the response message to IO thread? Is there a standard/best practice? Thank you.

  • How can I get a 302 redirection URL's Location header in PHP?

    - by QAH
    I am trying to find a universal way to expand most if not all of the shortened URLs out there. I know short URLs such as bit.ly, TinyURL, goo.gl, etc use the 302 redirection method to redirect you to another site. How can I make a HEAD request to the shortened URL in php and get the "Location" part of the header? Please help me with this. Thanks

  • SQL SERVER – ASYNC_IO_COMPLETION – Wait Type – Day 11 of 28

    - by pinaldave
    For any good system three things are vital: CPU, Memory and IO (disk). Among these three, IO is the most crucial factor of SQL Server. Looking at real-world cases, I do not see IT people upgrading CPU and Memory frequently. However, the disk is often upgraded for either improving the space, speed or throughput. Today we will look at another IO-related wait type. From Book On-Line: Occurs when a task is waiting for I/Os to finish. ASYNC_IO_COMPLETION Explanation: Any tasks are waiting for I/O to finish. If by any means your application that’s connected to SQL Server is processing the data very slowly, this type of wait can occur. Several long-running database operations like BACKUP, CREATE DATABASE, ALTER DATABASE or other operations can also create this wait type. Reducing ASYNC_IO_COMPLETION wait: When it is an issue related to IO, one should check for the following things associated to IO subsystem: Look at the programming and see if there is any application code which processes the data slowly (like inefficient loop, etc.). Note that it should be re-written to avoid this  wait type. Proper placing of the files is very important. We should check the file system for proper placement of the files – LDF and MDF on separate drive, TempDB on another separate drive, hot spot tables on separate filegroup (and on separate disk), etc. Check the File Statistics and see if there is a higher IO Read and IO Write Stall SQL SERVER – Get File Statistics Using fn_virtualfilestats. Check event log and error log for any errors or warnings related to IO. If you are using SAN (Storage Area Network), check the throughput of the SAN system as well as configuration of the HBA Queue Depth. In one of my recent projects, the SAN was performing really badly and so the SAN administrator did not accept it. After some investigations, he agreed to change the HBA Queue Depth on the development setup (test environment). As soon as we changed the HBA Queue Depth to quite a higher value, there was a sudden big improvement in the performance. It is very likely to happen that there are no proper indexes on the system and yet there are lots of table scans and heap scans. Creating proper index can reduce the IO bandwidth considerably. If SQL Server can use appropriate cover index instead of clustered index, it can effectively reduce lots of CPU, Memory and IO (considering cover index has lesser columns than cluster table and all other; it depends upon the situation). You can refer to the following two articles I wrote that talk about how to optimize indexes: Create Missing Indexes Drop Unused Indexes Checking Memory Related Perfmon Counters SQLServer: Memory Manager\Memory Grants Pending (Consistent higher value than 0-2) SQLServer: Memory Manager\Memory Grants Outstanding (Consistent higher value, Benchmark) SQLServer: Buffer Manager\Buffer Hit Cache Ratio (Higher is better, greater than 90% for usually smooth running system) SQLServer: Buffer Manager\Page Life Expectancy (Consistent lower value than 300 seconds) Memory: Available Mbytes (Information only) Memory: Page Faults/sec (Benchmark only) Memory: Pages/sec (Benchmark only) Checking Disk Related Perfmon Counters Average Disk sec/Read (Consistent higher value than 4-8 millisecond is not good) Average Disk sec/Write (Consistent higher value than 4-8 millisecond is not good) Average Disk Read/Write Queue Length (Consistent higher value than benchmark is not good) Read all the post in the Wait Types and Queue series. Note: The information presented here is from my experience and there is no way that I claim it to be accurate. I suggest reading Book OnLine for further clarification. All the discussions of Wait Stats in this blog are generic and vary from system to system. It is recommended that you test this on a development server before implementing it to a production server.

  • Question marks showing in ls of directory. IO errors too.

    - by jaymoo
    Has anyone seen this before? I've got a raid 5 mounted on my server and for whatever reason it started showing this: jason@box2:/mnt/raid1/cra$ ls -alh ls: cannot access e6eacc985fea729b2d5bc74078632738: Input/output error ls: cannot access 257ad35ee0b12a714530c30dccf9210f: Input/output error total 0 drwxr-xr-x 5 root root 123 2009-08-19 16:33 . drwxr-xr-x 3 root root 16 2009-08-14 17:15 .. ?????????? ? ? ? ? ? 257ad35ee0b12a714530c30dccf9210f drwxr-xr-x 3 root root 57 2009-08-19 16:58 9c89a78e93ae6738e01136db9153361b ?????????? ? ? ? ? ? e6eacc985fea729b2d5bc74078632738 The md5 strings are actual directory names and not part of the error. The question marks are odd, and any directory with a question mark throws an io error when you attempt to use/delete/etc it. I was unable to umount the drive due to "busy". Rebooting the server "fixed" it but it was throwing some raid errors on shutdown. I have configured two raid 5 arrays and both started doing this on random files. Both are using the following config: mkfs.xfs -l size=128m -d agcount=32 mount -t xfs -o noatime,logbufs=8 Nothing too fancy, but part of an optimized config for this box. We're not partitioning the drives and that was suggested as a possible issue. Could this be the culprit?

  • StackOverFlowError while creating Mac object on AS400/Java

    - by Prasanna K Rao
    Hello all, I am a newbie to AS400-Java programming. I am trying to create my first program to test the implementation of Message Authentication Code (MAC). I am trying to use the HMACSHA1 hash function. My (Java 1.4) program runs fine on a dev box (V5R4).But fails terribly on the QA box (V5R3). My program is as below: ===================================================== import java.security.InvalidKeyException; import java.security.NoSuchAlgorithmException; import java.security.Security; import java.security.Provider; import javax.crypto.Mac; import javax.crypto.spec.SecretKeySpec; import javax.crypto.SecretKey; public class Test01 { private static final String HMAC_SHA1_ALGORITHM = "HmacSHA1"; public static void main (String [] arguments) { byte[] key = { 1,2,3,4,5,6,7,8}; SecretKeySpec SHA1key = new SecretKeySpec(key, "HmacSHA1"); Mac hmac; String strFinalRslt = ""; try { hmac = Mac.getInstance("HmacSHA1"); hmac.init(SHA1key); byte[] result = hmac.doFinal(); strFinalRslt = toHexString(result); }catch (NoSuchAlgorithmException e) { // TODO Auto-generated catch block e.printStackTrace(); }catch (InvalidKeyException e) { // TODO Auto-generated catch block e.printStackTrace(); }catch(StackOverflowError e){ e.printStackTrace(); } System.out.println(strFinalRslt); System.out.println("All done!!!"); } public static byte[] fromHexString ( String s ) { int stringLength = s.length(); if ( (stringLength & 0x1) != 0 ) { throw new IllegalArgumentException ( "fromHexString requires an even number of hex characters" ); } byte[] b = new byte[stringLength / 2]; for ( int i=0,j=0; i 4] ); //look up low nibble char sb.append( hexChar [b[i] & 0x0f] ); } return sb.toString(); } static char[] hexChar = { '0' , '1' , '2' , '3' , '4' , '5' , '6' , '7' , '8' , '9' , 'a' , 'b' , 'c' , 'd' , 'e' , 'f'}; } This program compiles fine and gets the correct response on my win-xp client and also my dev box. But, fails with the following error on the QA box: java.lang.StackOverflowError at java.lang.Throwable.(Throwable.java:180) at java.lang.Error.(Error.java:37) at java.lang.StackOverflowError.(StackOverflowError.java:24) at java.io.Os400FileSystem.list(Native method) at java.io.File.list(File.java:922) at javax.crypto.b.e(Unknown source) at javax.crypto.b.a(Unknown source) at javax.crypto.b.c(Unknown source) at javax.crypto.b£0.run(Unknown source) at javax.crypto.b.(Unknown source) at javax.crypto.Mac.getInstance(Unknown source) I have verified the java.security file and entry corresponding to the jce files are all ok.

  • Is there any way that an export-to-Excel function can be scalable?

    - by MusiGenesis
    Summary: ASP.Net website with a couple hundred users. Data is exported to Excel files which can be relatively large (~5 MB). In the pilot phase (just a few users), we are already seeing occasional errors on the server in the exporting method.

Is there any general way to export to Excel in a "light-weight" manner? Would simply streaming the data into a CSV file work for this?

  • How can I link two Java serialised objects back together?

    - by Kidburla
    Sometimes (quite a lot, actually) we get a situation in Java where two objects are pointing to the same thing. Now if we serialise these separately it is quite appropriate that the serialised forms have separate copies of the object as it should be possible to open one without the other. However if we now deserialise them both, we find that they are still separated. Is there any way to link them back together? Example follows. public class Example { private static class ContainerClass implements java.io.Serializable { private ReferencedClass obj; public ReferencedClass get() { return obj; } public void set(ReferencedClass obj) { this.obj = obj; } } private static class ReferencedClass implements java.io.Serializable { private int i = 0; public int get() { return i; } public void set(int i) { this.i = i; } } public static void main(String[] args) throws Exception { //Initialise the classes ContainerClass test1 = new ContainerClass(); ContainerClass test2 = new ContainerClass(); ReferencedClass ref = new ReferencedClass(); //Make both container class point to the same reference test1.set(ref); test2.set(ref); //This does what we expect: setting the integer in one (way of accessing the) referenced class sets it in the other one test1.get().set(1234); System.out.println(Integer.toString(test2.get().get())); //Now serialise the container classes java.io.ObjectOutputStream os = new java.io.ObjectOutputStream(new java.io.FileOutputStream("C:\\Users\\Public\\test1.ser")); os.writeObject(test1); os.close(); os = new java.io.ObjectOutputStream(new java.io.FileOutputStream("C:\\Users\\Public\\test2.ser")); os.writeObject(test2); os.close(); //And deserialise them java.io.ObjectInputStream is = new java.io.ObjectInputStream(new java.io.FileInputStream("C:\\Users\\Public\\test1.ser")); ContainerClass test3 = (ContainerClass)is.readObject(); is.close(); is = new java.io.ObjectInputStream(new java.io.FileInputStream("C:\\Users\\Public\\test2.ser")); ContainerClass test4 = (ContainerClass)is.readObject(); is.close(); //We expect the same thing as before, and would expect a result of 4321, but this doesn't happen as the referenced objects are now separate instances test3.get().set(4321); System.out.println(Integer.toString(test4.get().get())); } }

  • Bioperl, equivalent of IO::ScalarArray for array of Seq objects?

    - by Ryan Thompson
    In perl, we have IO::ScalarArray for treating the elements of an array like the lines of a file. In BioPerl, we have Bio::SeqIO, which can produce a filehandle that reads and writes Bio::Seq objects instead of strings representing lines of text. I would like to do a combination of the two: I would like to obtain a handle that reads successive Bio::Seq objects from an array of such objects. Is there any way to do this? Would it be trivial for me to implement a module that does this? My reason for wanting this is that I would like to be able to write a subroutine that accepts either a Bio::SeqIO handle or an array of Bio::Seq objects, and I'd like to avoid writing separate loops based on what kind of input I get. Perhaps the following would be better than writing my own IO module? sub process_sequences { my $input = $_[0]; # read either from array of Bio::Seq or from Bio::SeqIO my $nextseq; if (ref $input eq 'ARRAY') { my $pos = 0 $nextseq = sub { return $input->[$pos++] if $pos < @$input}; } } else { $nextseq = sub { $input->getline(); } } while (my $seq = $nextseq->()) { do_cool_stuff_with($seq) } }

  • Why is syslog so much slower than file IO?

    - by ceving
    I wrote a simple test program to measure the performance of the syslog function. This are the results of my test system: (Debian 6.0.2 with Linux 2.6.32-5-amd64) Test Case Calls Payload Duration Thoughput [] [MB] [s] [MB/s] -------------------- ---------- ---------- ---------- ---------- syslog 200000 10.00 7.81 1.28 syslog %s 200000 10.00 9.94 1.01 write /dev/null 200000 10.00 0.03 343.93 printf %s 200000 10.00 0.13 76.29 The test program did 200000 system calls writing 50 Bytes of data during each call. Why is Syslog more than ten times slower than file IO? This is the program I used to perform the test: #include <fcntl.h> #include <stdio.h> #include <string.h> #include <sys/stat.h> #include <sys/time.h> #include <sys/types.h> #include <syslog.h> #include <unistd.h> const int iter = 200000; const char msg[] = "123456789 123456789 123456789 123456789 123456789"; struct timeval t0; struct timeval t1; void start () { gettimeofday (&t0, (void*)0); } void stop () { gettimeofday (&t1, (void*)0); } void report (char *action) { double dt = (double)t1.tv_sec - (double)t0.tv_sec + 1e-6 * ((double)t1.tv_usec - (double)t0.tv_usec); double mb = 1e-6 * sizeof (msg) * iter; if (action == NULL) printf ("Test Case Calls Payload Duration Thoughput \n" " [] [MB] [s] [MB/s] \n" "-------------------- ---------- ---------- ---------- ----------\n"); else { if (strlen (action) > 20) action[20] = 0; printf ("%-20s %-10d %-10.2f %-10.2f %-10.2f\n", action, iter, mb, dt, mb / dt); } } void test_syslog () { int i; openlog ("test_syslog", LOG_PID | LOG_NDELAY, LOG_LOCAL0); start (); for (i = 0; i < iter; i++) syslog (LOG_DEBUG, msg); stop (); closelog (); report ("syslog"); } void test_syslog_format () { int i; openlog ("test_syslog", LOG_PID | LOG_NDELAY, LOG_LOCAL0); start (); for (i = 0; i < iter; i++) syslog (LOG_DEBUG, "%s", msg); stop (); closelog (); report ("syslog %s"); } void test_write_devnull () { int i, fd; fd = open ("/dev/null", O_WRONLY); start (); for (i = 0; i < iter; i++) write (fd, msg, sizeof(msg)); stop (); close (fd); report ("write /dev/null"); } void test_printf () { int i; FILE *fp; fp = fopen ("/tmp/test_printf", "w"); start (); for (i = 0; i < iter; i++) fprintf (fp, "%s", msg); stop (); fclose (fp); report ("printf %s"); } int main (int argc, char **argv) { report (NULL); test_syslog (); test_syslog_format (); test_write_devnull (); test_printf (); }

  • How do I convert a System::IO::Stream^ to an LPCSTR for PlaySound?

    - by Jon Cage
    I'm trying to embed and then play back a .wav file in a C++/CLI app but all the examples I've seen which use PlaySound are in VB. I can't see how to get froma Stream^ to the LPCSTR which PlaySound requires: System::IO::Stream^ s = Assembly::GetExecutingAssembly()->GetManifestResourceStream ("Ping.wav"); LPCSTR buf = s->????; PlaySound(buf, NULL, SND_ASYNC|SND_MEMORY|SND_NOWAIT); I guess I need some sort of horrible .net memory conversion magic.

  • How do I define my own operators in the Io programming language?

    - by klep
    I'm trying to define my own operator in Io, and I'm having a hard time. I have an object: MyObject := Object clone do( lst := list() !! := method(n, lst at(n)) ) But when I call it, like this: x := MyObject clone do(lst appendSeq(list(1, 2, 3))) x !! 2 But I get an exception that argument 0 to at must not be nil. How can I fix?

  • System.IO.File.ReadAllText(path) does not read the html file.

    - by Harikrishna
    I want to read the html file.And for that I use System.IO.File.ReadAllText(path).It can read all the html file but there is one file which is not read through this function. I have also used using (StreamReader reader = File.OpenText(fileName)) { text = reader.ReadToEnd(); But still there is same problem. What is the reason can be there ? And for that what can be the solution ? Or any other way to read the file ?
