  • Ubuntu missing from the Grub menu

    - by varevarao
    Recently I've had some audio issues with Ubuntu (using precise), and in the process of trying to resolve that I ran a dist-upgrade. Everything went just fine, and the sound seemed good, until I rebooted my machine for the first time since the dist-upgrade. All I see now in the Grub menu at startup is memtest86+, another memtest variant, and Windows 7. It's not showing any of the linux kernels that Ubuntu is running on. I am attaching my bootinfoscript: Boot Info Script 0.61.full + Boot-Repair extra info [Boot-Info November 20th 2012] ============================= Boot Info Summary: =============================== => Grub2 (v1.99) is installed in the MBR of /dev/sda and looks at sector 1 of the same hard drive for core.img. core.img is at this location and looks for (,msdos6)/boot/grub on this drive. sda1: __________________________________________________________________________ File system: vfat Boot sector type: Dell Utility: FAT16 Boot sector info: No errors found in the Boot Parameter Block.

Error: failure: repodata/updateinfo.xml.gz from updates: [Errno 256] No more mirrors to try. You could try using --skip-broken to work around the problem ^C[root@localhost /]# As it can be seen in the output, when I run the yum --security update command, it did show the Limiting packages to security relevant ones message so it's aware of the option. But I don't know why it keeps reporting the http error 416. I searched in google and found the following description of the error but it doesn't seem to help much. HTTP ERROR 416 - Requested Range Not Satisfiable A 416 status code indicates that the server was unable to fulfill the request. This may be, for example, because the client asked for the 800th-900th bytes of a document, but the document was only 200 bytes long. It suggests me to use the --skip-broken option, I tried and the output is the same. I already tested many times, it just doesn't work when the --security option is used. What could be the possible cause for this problem?

  • SSL / HTTP / No Response to Curl

    - by Alex McHale
    I am trying to send commands to a SOAP service, and getting nothing in reply. The SOAP service is at a completely separate site from either server I am testing with. I have written a dummy script with the SOAP XML embedded. When I run it at my local site, on any of three machines -- OSX, Ubuntu, or CentOS 5.3 -- it completes successfully with a good response. I then sent the script to our public host at Slicehost, where I fail to get the response back from the SOAP service. It accepts the TCP socket and proceeds with the SSL handshake. I do not however receive any valid HTTP response. This is the case whether I use my script or curl on the command line. I have rewritten the script using SOAP4R, Net::HTTP and Curb. All of which work at my local site, none of which work at the Slicehost site. I have tried to assemble the CentOS box as closely to match my Slicehost server as possible. I rebuilt the Slice to be a stock CentOS 5.3 and stock CentOS 5.4 with the same results. When I look at a tcpdump of the bad sessions on Slicehost, I see my script or curl send the XML to the remote server, and nothing comes back. When I look at the tcpdump at my local site, I see the response just fine. I have entirely disabled iptables on the Slice. Does anyone have any ideas what could be causing these results? Please let me know what additional information I can furnish. Thank you! Below is a wire trace of a sample session. The IP that starts with 173 is my server while the IP that starts with 12 is the SOAP server's.

  • mysqld crashes on any statement

    - by ??iu
    I restarted my slave to change configuration settings to skip reverse hostname lookup on connecting and to enable the slow query log. I edited /etc/my.cnf making only these changes, then restarted mysqld with /etc/init.d/mysql restart All appeared to be well but when I connect to msyqld remotely or locally though it connects okay a slight problem is that mysqld crashes whenever you try to issue any kind of statement. The client looks like: Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Welcome to the MySQL monitor.

  • Wireless access point -> Powerline -> Router -> Internet, should this work?

    - by Anthony
    My network at home used to be a laptop and desktop connected wirelessly to a single Wireless ADSL router, a Cisco 877W. Wireless reception around the house with this setup was quite unreliable, so I've gone about looking to improve it. I purchased some Belkin Gigabit powerline adapters and I've got these working fine. I can hook a computer up to one of the powerline adapters, and with the other one plugged into the ADSL router the computer has internet access. Additionally I can hook a Netgear DG834G Wireless ADSL router into it with the adsl not plugged in, and after turning off DHCP can RJ45 a computer up to the network. Everything works fine. However, if I setup a wireless network on the Netgear then any computer that connects wirelessly to it cannot access the internet. It gets an IP address very slowly via DHCP which is a good one, but it cannot access the internet. It can however communicate with the RJ45'd computer also connected to the Netgear. I wondered whether this could be a problem with the Netgear so I've borrowed a Cisco Aironet 1200 and got this working fine when it's attached directly to the primary ADSL router. I can connect to it wireless and get onto the internet. However, if I then plug it into the Netgear I can communicate with other devices attached to the Netgear, but can't get any further than the Netgear. All the while though the other devices RJ45'd to the Netgear are communicating with the internet just fine. I'm starting to suspect it's one of two things causing the problem: 1) For some reason the belkin powerline adapters don't like carrying wireless-originating signals. Could this be possible? 2) The primary Cisco ADSL router doesn't want to communicate with other devices on my network more than one hop away from it. I'm making an assumption here that within the Netgear box the wireless and wired sides are handled differently. Could this be true? Has anyone successfully setup something similar to what I'm trying, with a wireless device on the otherside of a pair of powerline connectors? Update 06/07/2010 - Response to irrational John 28 June Thanks for the answer John - and for clearing up some of my questions. The model number of the belkin powerline adapters are F5D4076. Security was apparently enabled by default on them, and I didn't change them from their default setting. The network diagram in your answer shows exactly what I'm trying to setup: I've followed that guide and I'm still not able to get things working properly. The thing that perplexes me is that wired network traffic works just fine - it's only the wireless traffic that doesn't. This is with the same laptop, and the same DHCP or static IPs. "1. What IP addresses did you assign to each router? What subnet masks are you using?" - subnet is 255.255.255.0, the router connected to the adsl is 192.168.153.1 and that has the DHCP server. The access point on the other side of the powerline adapters I've tried both a static IP of 192.168.153.110, same subnet, and a DHCP-assigned IP. The other devices are DHCP, although I also tried manually entering IP settings. "2. Have you correctly enabled DHCP on only one of the routers and disabled it on all the others?" Yes I have - only the internet-connected router has DHCP enabled. The IP range for the DHCP is from 192.168.153.11 - 192.168.153.200. The strange thing is that wired connections work fine on the LAN, plugged into any router, work fine - it's only the wireless connections that aren't working when they're plugged into the non-primary AP. "Since the routers you are using appear to integrate an ADSL modem I'm assuming there is no WAN port on them." There's no NAT within the LAN, and all wired connections are connected to LAN ports. It's something wrong with the wireless - wired works fine throughout the whole LAN. Update 06/07/2010 - Response to irrational John 29 June The diagram you've drawn in your answer shows pretty much exactly what I'm trying to do. I've spent another evening trying different things and made some progress but I'm still scratching my head. I've borrowed a Netgear access point and been trying with this, and the strange thing is that my PC is working now - this is a Windows 7 PC connected to the access point in the position of where the DG834G is in the diagram. Meanwhile, however, I have an old Powerbook G4 12" I use for music, and while that has a DHCP-assigned IP address, it's not getting any network throughput to either LAN or internet addresses. To make matters more strange, my phone appears to be intermittently working when it's on the wifi. The access point is a Netgear WPN802v1, DHCP, NAT both switched off, running firmware 2.0.9.0. Last night I set it up with exactly the same settings, and similar to tonight I could get a couple of devices to work, and a couple not to. By the morning, however, everything had stopped working - nothing could get a DHCP IP address. I rebooted the 877W earlier this evening and I'm wondering whether this is why a few things are working now. "Could it be possible that the issue could be with the 877W?" I didn't configure this - is it possible that the DHCP server only likes assigning devices that are immediately attached to it? Or similar, could a firewall be stopping too many addresses that are coming through one device? (ie. the Access Point) This could explain why devices are working at the start but then not by the end. In reply to your questions, "1. I looked at the Netgear DG834G support page. There are five versions of this router. Which version do you have? Netgear usually lists this on the label on the bottom of the router. What version of the firmware does it have?" It's a DG834Gv3, and the firmware is the last on the netgear site version 4.01.40. "3. Not knowing which version you have, I glanced at the reference manual for the DG834G v3. In the section for Wireless Settings under the subsection Wireless Access Point there is a check box for a Wireless Isolation setting. If you have this setting it should be off/unchecked. If it is checked then any device connected via wireless would not be able to talk to any other device on the LAN. This sounds like your problem so maybe this is the cause?" I've checked this and it's switched off. I've made a change to the IP of the access point to something outside the DHCP range - it's now 192.158.153.5, with DHCP starting at 11 and going up to 254. Thanks for the tip about this - I only have a few devices so wouldn't anticipate the DHCP server assigning up to 110, but better safe than sorry. Finally one more thing I thought I should add, is with the Powerbook G4 that's not working - it's getting a DHCP IP address and it can communicate with the WPN802 as I can visit the administration page. Anything further than this, however, it can't reach; I can't administrate the 192.168.153.1 (877W router). Strangely, however, when I open Finder on the same powerbook it's detecting my NAS which is attached directly via wire to the 877W. If I try to browse it, it says connection failed. RE: "Perhaps the problem with your Powerbook is with DNS?.." The IP settings on the powerbook are identical to that of the PC with the exception of the IP address; the PC is 192.168.153.17 and the powerbook is 192.168.153.12. Subnets are the same, 255.255.255.0 and default gateway is the same, .1, and the DNS servers are the same. I administrate the 877W by going to 192.168.153.1 in the browser. This is what isn't working from the Powerbook, despite the PC working fine when I do the same. Meanwhile, however, I can administrate the AP on 192.168.153.5 from both PC and Powerbook Update 06/07/2010 - FINAL RESOLUTION of sorts: First off, sorry for the length of this question. I need start to practice a more concise writing style, so I'm going to try to keep this bit brief. After much fiddling, and with the hugely-appreciated help of irrational John, I have come to the conclusion that it's something wrong with the powerbook. I believe that this was perhaps the reason I doubted things worked at the very beginning. I now have the original DG834Gv3 running both wirelessly and wired, and both wired devices and wireless devices get internet connectivity. The only anomaly is the powerbook which I've had to keep wired, as no matter what I do it refuses to work wirelessly. I still have suspicions that the 877W isn't quite right; I'm fairly sure that if I RJ45 the powerline adapter into a different LAN port on it then everything will break. I've just about run out of patience to test this further, and I think I need to go into the 877W's config to match the 877w's lan port's settings. I'm accepting irrational John's answer as he's been enormously helpful, way above the call of duty, and for this line he wrote: Beats the heck out of me. which in the midst of great frustration made me chuckle, and for a sentence in one of his comments to the same answer: If it is specific to the Powerbook I would put that issue aside until after you feel you have the rest of your LAN and the additional WAP all working together correctlyt It was this second sentence that made me put the powerbook aside and concentrate on the other devices that ultimately led me to getting things working.

  • Set up linux box for secure local hosting a-z

    - by microchasm
    I am in the process of reinstalling the OS on a machine that will be used to host a couple of apps for our business. The apps will be local only; access from external clients will be via vpn only. The prior setup used a hosting control panel (Plesk) for most of the admin, and I was looking at using another similar piece of software for the reinstall - but I figured I should finally learn how it all works. I can do most of the things the software would do for me, but am unclear on the symbiosis of it all. This is all an attempt to further distance myself from the land of Configuration Programmer/Programmer, if at all possible. I can't find a full walkthrough anywhere for what I'm looking for, so I thought I'd put up this question, and if people can help me on the way I will edit this with the answers, and document my progress/pitfalls. Hopefully someday this will help someone down the line. The details: CentOS 5.5 x86_64 httpd: Apache/2.2.3 mysql: 5.0.77 (to be upgraded) php: 5.1 (to be upgraded) The requirements: SECURITY!! Secure file transfer Secure client access (SSL Certs and CA) Secure data storage Virtualhosts/multiple subdomains Local email would be nice, but not critical The Steps: Download latest CentOS DVD-iso (torrent worked great for me). Install CentOS: While going through the install, I checked the Server Components option thinking I was going to be using another Plesk-like admin. In hindsight, considering I've decided to try to go my own way, this probably wasn't the best idea. Basic config: Setup users, networking/ip address etc. Yum update/upgrade. Upgrade PHP/MySQL: To upgrade PHP and MySQL to the latest versions, I had to look to another repo outside CentOS. IUS looks great and I'm happy I found it!

I tried browsing to it, and was met with permission denied errors.

However, the CentOS documentation for BIND can be found here: http://www.centos.org/docs/5/html/Deployment_Guide-en-US/ch-bind.html SSL To get SSL working, I changed the following in httpd.conf: NameVirtualHost 192.168.1.3:443 #make sure this line is in httpd.conf <VirtualHost 192.168.1.3:443> #change port to 443 ServerAdmin [email protected] DocumentRoot /home/dev/https ServerName dev.site.local ErrorLog /home/dev/logs/error_log TransferLog /home/dev/logs/access_log </VirtualHost> Unfortunately, I keep getting (Error code: ssl_error_rx_record_too_long) errors when trying to access a page with SSL. As JamesHannah gracefully pointed out below, I had not set up the locations of the certs in httpd.conf, and thusly was getting the page thrown at the broswer as the cert making the browser balk. So first, I needed to set up a CA and make certificate files. I found a great (if old) walkthrough on the process here: http://www.debian-administration.org/articles/284. Here are the relevant steps I took from that article: mkdir /home/CA cd /home/CA/ mkdir newcerts private echo '01' > serial touch index.txt #this and the above command are for the database that will keep track of certs Create an openssl.cnf file in the /home/CA/ dir and edit it per the walkthrough linked above. (For reference, my finished openssl.cnf file looked like this: http://pastebin.com/raw.php?i=hnZDij4T) openssl req -new -x509 -extensions v3_ca -keyout private/cakey.pem -out cacert.pem -days 3650 -config ./openssl.cnf #this creates the cacert.pem which gets distributed and imported to the browser(s) Modified openssl.cnf again per walkthrough instructions. openssl req -new -nodes -out dev.req.pem -config ./openssl.cnf #generates certificate request, and key.pem which I renamed dev.key.pem.

Now I can visit https://dev.site.local with no errors or warnings. And this is where I'm at. I will keep editing this as I make progress. Any tips on how to configure SSL email would be appreciated.

  • FreeBSD 8.1 unstable network connection

    - by frankcheong
    I have three FreeBSD 8.1 running on three different hardware and therefore consist of different network adapter as well (bce, bge and igb). I found that the network connection is kind of unstable which I have tried to scp some 10MB file and found that I cannot always get the files completed successfully. I have further checked with my network admin and he claim that the problem is being caused by the network driver which cannot support the load whereby he tried to ping using huge packet size (around 15k) and my server will drop packet consistently at a regular interval. I found that this statement may not be valid since the three server is using three different network drive and it would be quite impossible that the same problem is being caused by three different network adapter and thus different network driver.

  • Command does not execute in crontab while command itself works just fine

    - by fuzzybee
    I have this script from Colin Johnson on Github - https://github.com/colinbjohnson/aws-missing-tools/tree/master/ec2-automate-backup It seems great. I have modified it to send email to myself every time an EBS snapshot is created or deleted. The following works like a charm ec2-automate-backup.sh -v "vol-myvolumeid" -k 3 However, it does not execute at all as part of my crontab (I didn't receive any emails) #some command that got commented out */5 * * * * ec2-automate-backup.sh -v "vol-fb2fbcdf" -k 3; * * * * * date /root/logs/crontab.log; */5 * * * * date /root/logs/crontab2.log Please note that the 2nd and 3rd execute just fines as I can see the date and time in log files.

  • MySQL query, 2 similar servers, 2 minute difference in execution times

    I had a similar question on stack overflow, but it seems to be more server/mysql setup related than coding. The queries below all execute instantly on our development server where as they can take upto 2 minutes 20 seconds. The query execution time seems to be affected by home ambiguous the LIKE string's are. If they closely match a country that has few matches it will take less time, and if you use something like 'ge' for germany - it will take longer to execute. But this doesn't always work out like that, at times its quite erratic. Sending data appears to be the culprit but why and what does that mean. Also memory on production looks to be quite low (free memory)?

  • mysqld crashes on any statement

    - by ??iu
    I restarted my slave to change configuration settings to skip reverse hostname lookup on connecting and to enable the slow query log. I edited /etc/my.cnf making only these changes, then restarted mysqld with /etc/init.d/mysql restart All appeared to be well but when I connect to msyqld remotely or locally though it connects okay a slight problem is that mysqld crashes whenever you try to issue any kind of statement.

  • How do I set the encoding statement in the XML declaration when performing an XSL transformation usi

    - by aspiehler
    I wrote a simple package installer in WinBatch that needs to update an XML file with information about the package contents. My first stab at it involved loading the file with Msxml2.DOMDocument, adding nodes and data as required, then saving the data back to disk. This worked well enough, except that it would not create tab and CR/LF whitespace in the new data. The solution I came up with was writing an XSL stylesheet that would recreate the XML file with whitespace added back in. I'm doing this by: loading the XSL file into an Msxml2.FreeThreadedDOMDocument object setting that object as the stylesheet property of an Msxml2.XSLTemplate object creating an XSL processor via Msxml2.XSLTemplate.createProcessor() setting my original Msxml2.DOMDocument as the input property of the XSL processor Calling transform() method of the XSL processor, and saving the output to a file. This works as for as reformatting the XML file with tabs and carriage returns, but my XML declaration comes out either as <?xml version="1.0"?> or <?xml version="1.0" encoding="UTF-16"?> depending on whether I used Msxml2.*.6.0 or Msxml2.* objects (a fall back if the system doesn't have 6.0). If the encoding is set to UTF-16, Msxml12.DOMDocument complains about trying to convert UTF-16 to 1-byte encoding the next time I run my package installer. I've tried creating and adding an XML declaration using both createProcessingInstruction() to both the XML and XSL DOM objects, but neither one seems to affect the output of the XSLTemplate processor. I've also set encoding to UTF-8 in the <xsl:output/> tag in my XSL file. Here is the relevant code in my Winbatch script: xmlDoc = ObjectCreate("Msxml2.DOMDocument.6.0") if !xmlDoc then xmlDoc = ObjectCreate("Msxml2.DOMDocument") xmlDoc.async = @FALSE xmlDoc.validateOnParse = @TRUE xmlDoc.resolveExternals = @TRUE xmlDoc.preserveWhiteSpace = @TRUE xmlDoc.setProperty("SelectionLanguge", "XPath") xmlDoc.setProperty("SelectionNamespaces", "xmlns:fns='http://www.abc.com/f_namespace'") xmlDoc.load(xml_file_path) xslStyleSheet = ObjectCreate("Msxml2.FreeThreadedDOMDocument.6.0") if !xslStyleSheet then xslStyleSheet = ObjectCreate("Msxml2.FreeThreadedDOMDocument") xslStyleSheet.async = @FALSE xslStyleSheet.validateOnParse = @TRUE xslStyleSheet.load(xsl_style_sheet_path) xslTemplate = ObjectCreate("Msxml2.XSLTemplate.6.0") if !xslTemplate then xslTemplate = ObjectCreate("Msxml2.XSLTemplate") xslTemplate.stylesheet = xslStyleSheet processor = xslTemplate.createProcessor() processor.input = xmlDoc processor.transform() ; create a new file and write the XML processor output to it fh = FileOpen(output_file_path, "WRITE" , @FALSE) FileWrite(fh, processor.output) FileClose(fh) The style sheet, with some slight changes to protect the innocent: <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.1"> <xsl:output method="xml" indent="yes" encoding="UTF-8"/> <xsl:template match="/"> <fns:test_station xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:fns="http://www.abc.com/f_namespace"> <xsl:for-each select="/fns:test_station/identification"> <xsl:text>&#x0A; </xsl:text> <identification> <xsl:for-each select="./*"> <xsl:text>&#x0A; </xsl:text> <xsl:copy-of select="."/> </xsl:for-each> <xsl:text>&#x0A; </xsl:text> </identification> </xsl:for-each> <xsl:for-each select="/fns:test_station/software"> <xsl:text>&#x0A; </xsl:text> <software> <xsl:for-each select="./package"> <xsl:text>&#x0A; </xsl:text> <package> <xsl:for-each select="./*"> <xsl:text>&#x0A; </xsl:text> <xsl:copy-of select="."/> </xsl:for-each> <xsl:text>&#x0A; </xsl:text> </package> </xsl:for-each> <xsl:text>&#x0A; </xsl:text> </software> </xsl:for-each> <xsl:for-each select="/fns:test_station/calibration"> <xsl:text>&#x0A; </xsl:text> <calibration> <xsl:for-each select="./item"> <xsl:text>&#x0A; </xsl:text> <item> <xsl:for-each select="./*"> <xsl:text>&#x0A; </xsl:text> <xsl:copy-of select="."/> </xsl:for-each> <xsl:text>&#x0A; </xsl:text> </item> </xsl:for-each> <xsl:text>&#x0A; </xsl:text> </calibration> </xsl:for-each> </fns:test_station> </xsl:template> </xsl:stylesheet> And this is a sample output file: <?xml version="1.0" encoding="UTF-16"?> <fns:test_station xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:fns="http://www.abc.com/f_namespace"> <software> <package> <part_number>123456789</part_number> <version>00</version> <test_category>1</test_category> <description>name of software package</description> <execution_path>c:\program files\test\test.exe</execution_path> <execution_arguments>arguments</execution_arguments> <crc_path>c:\ste_config\crc\123456789.lst</crc_path> <uninstall_path>c:\ste_config\uninstall\uninst_123456789.bat</uninstall_path> <install_timestamp>2009-11-09T14:00:44</install_timestamp> </package> </software> </fns:test_station>

  • Please help me understand why my XSL Transform is not transforming

    - by Damovisa
    I'm trying to transform one XML format to another using XSL. Try as I might, I can't seem to get a result. I've hacked away at this for a while now and I've had no success. I'm not even getting any exceptions. I'm going to post the entire code and hopefully someone can help me work out what I've done wrong. I'm aware there are likely to be problems in the xsl I have in terms of selects and matches, but I'm not fussed about that at the moment. The output I'm getting is the input XML without any XML tags. The transformation is simply not occurring.

  • actionscript3: reflect-class applied on rotationY

    - by algro
    Hi, I'm using a class which applies a visual reflection-effect to defined movieclips. I use a reflection-class from here: link to source. It works like a charm except when I apply a rotation to the movieclip. In my case the reflection is still visible but only a part of it. What am I doing wrong? How could I pass/include the rotation to the Reflection-Class ? Thanks in advance! This is how you apply the Reflection Class to your movieclip: var ref_mc:MovieClip = new MoviClip(); addChild(ref_mc); var r1:Reflect = new Reflect({mc:ref_mc, alpha:50, ratio:50,distance:0, updateTime:0,reflectionDropoff:1}); Now I apply a rotation to my movieclip: ref_mc.rotationY = 30; And Here the Reflect-Class: package com.pixelfumes.reflect{ import flash.display.MovieClip; import flash.display.DisplayObject; import flash.display.BitmapData; import flash.display.Bitmap; import flash.geom.Matrix; import flash.display.GradientType; import flash.display.SpreadMethod; import flash.utils.setInterval; import flash.utils.clearInterval; public class Reflect extends MovieClip{ //Created By Ben Pritchard of Pixelfumes 2007 //Thanks to Mim, Jasper, Jason Merrill and all the others who //have contributed to the improvement of this class //static var for the version of this class private static var VERSION:String = "4.0";

  • Spring security - Reach users ID without passing it through every controller

    - by nilsi
    I have a design issue that I don't know how to solve. I'm using Spring 3.2.4 and Spring security 3.1.4. I have a Account table in my database that looks like this: create table Account (id identity, username varchar unique, password varchar not null, firstName varchar not null, lastName varchar not null, university varchar not null, primary key (id)); Until recently my username was just only a username but I changed it to be the email address instead since many users want to login with that instead. I have a header that I include on all my pages which got a link to the users profile like this: <a href="/project/users/<%= request.getUserPrincipal().getName()%>" class="navbar-link"><strong><%= request.getUserPrincipal().getName()%></strong></a> The problem is that <%= request.getUserPrincipal().getName()%> returns the email now, I don't want to link the user's with thier emails. Instead I want to use the id every user have to link to the profile. How do I reach the users id's from every page? I have been thinking of two solutions but I'm not sure: Change the principal to contain the id as well, don't know how to do this and having problem finding good information on the topic. Add a model attribute to all my controllers that contain the whole user but this would be really ugly, like this. Account account = entityManager.find(Account.class, email); model.addAttribute("account", account); There are more way's as well and I have no clue which one is to prefer. I hope it's clear enough and thank you for any help on this. ====== Edit according to answer ======= I edited Account to implement UserDetails, it now looks like this (will fix the auto generated stuff later): @Entity @Table(name="Account") public class Account implements UserDetails { @Id private int id; private String username; private String password; private String firstName; private String lastName; @ManyToOne private University university; public Account() { } public Account(String username, String password, String firstName, String lastName, University university) { this.username = username; this.password = password; this.firstName = firstName; this.lastName = lastName; this.university = university; } public String getUsername() { return username; } public String getPassword() { return password; } public String getFirstName() { return firstName; } public String getLastName() { return lastName; } public void setUsername(String username) { this.username = username; } public void setPassword(String password) { this.password = password; } public void setFirstName(String firstName) { this.firstName = firstName; } public void setLastName(String lastName) { this.lastName = lastName; } public University getUniversity() { return university; } public void setUniversity(University university) { this.university = university; } public int getId() { return id; } public void setId(int id) { this.id = id; } @Override public Collection<? extends GrantedAuthority> getAuthorities() { // TODO Auto-generated method stub return null; } @Override public boolean isAccountNonExpired() { // TODO Auto-generated method stub return false; } @Override public boolean isAccountNonLocked() { // TODO Auto-generated method stub return false; } @Override public boolean isCredentialsNonExpired() { // TODO Auto-generated method stub return false; } @Override public boolean isEnabled() { // TODO Auto-generated method stub return true; } } I also added <%@ taglib prefix="sec" uri="http://www.springframework.org/security/tags" %> To my jsp files and trying to reach the id by <sec:authentication property="principal.id" /> This gives me the following org.springframework.beans.NotReadablePropertyException: Invalid property 'principal.id' of bean class [org.springframework.security.authentication.UsernamePasswordAuthenticationToken]: Bean property 'principal.id' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter? ====== Edit 2 according to answer ======= I based my application on spring social samples and I never had to change anything until now. This are the files I think are relevant, please tell me if theres something you need to see besides this.

This is starting to be something else compared to my initial question, I should maybe start another question. Sorry for my lack of experience in this. I have to read up.

  • XSLT big integer (int64) handling msxml

    - by Farid Z
    When trying to do math on an big integer (int64) large number in xslt template I get the wrong result since there is no native 64-bit integer support in xslt (xslt number is 64-bit double). I am using msxml 6.0 on Windows XP SP3. Are there any work around for this on Windows? <tables> <table> <table_schem>REPADMIN</table_schem> <table_name>TEST_DESCEND_IDENTITY_BIGINT</table_name> <column> <col_name>COL1</col_name> <identity> <col_min_val>9223372036854775805</col_min_val> <col_max_val>9223372036854775805</col_max_val> <autoincrementvalue>9223372036854775807</autoincrementvalue> <autoincrementstart>9223372036854775807</autoincrementstart> <autoincrementinc>-1</autoincrementinc> </identity> </column> </table> </tables> This test returns true due to overflow (I am assuming) but actually is false if I could tell the xslt processor somehow to use int64 rather than the default 64-bit double for the data since big integer is the actual data type for the numbers in the xml input. <xsl:when test="autoincrementvalue = (col_min_val + autoincrementinc)"> <xsl:value-of select="''"/> </xsl:when> here is the complete template <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" > <!--Reseed Derby identity column--> <xsl:output omit-xml-declaration='yes' method='text' /> <xsl:param name="stmtsep">;</xsl:param> <xsl:param name="schemprefix"></xsl:param> <xsl:template match="tables"> <xsl:variable name="identitycount" select="count(table/column/identity)"></xsl:variable> <xsl:for-each select="table/column/identity"> <xsl:variable name="table_schem" select="../../table_schem"></xsl:variable> <xsl:variable name="table_name" select="../../table_name"></xsl:variable> <xsl:variable name="tablespec"> <xsl:if test="$schemprefix"> <xsl:value-of select="$table_schem"/>.</xsl:if><xsl:value-of select="$table_name"/></xsl:variable> <xsl:variable name="col_name" select="../col_name"></xsl:variable> <xsl:variable name="newstart"> <xsl:choose> <xsl:when test="autoincrementinc > 0"> <xsl:choose> <xsl:when test="col_max_val = '' and autoincrementvalue = autoincrementstart"> <xsl:value-of select="''"/> </xsl:when> <xsl:when test="col_max_val = ''"> <xsl:value-of select="autoincrementstart"/> </xsl:when> <xsl:when test="autoincrementvalue = (col_max_val + autoincrementinc)"> <xsl:value-of select="''"/> </xsl:when> <xsl:when test="(col_max_val + autoincrementinc) &lt; autoincrementstart"> <xsl:value-of select="autoincrementstart"/> </xsl:when> <xsl:otherwise> <xsl:value-of select="col_max_val + autoincrementinc"/> </xsl:otherwise> </xsl:choose> </xsl:when> <xsl:when test="autoincrementinc &lt; 0"> <xsl:choose> <xsl:when test="col_min_val = '' and autoincrementvalue = autoincrementstart"> <xsl:value-of select="''"/> </xsl:when> <xsl:when test="col_min_val = ''"> <xsl:value-of select="autoincrementstart"/> </xsl:when> <xsl:when test="autoincrementvalue = (col_min_val + autoincrementinc)"> <xsl:value-of select="''"/> </xsl:when> <xsl:when test="(col_min_val + autoincrementinc) > autoincrementstart"> <xsl:value-of select="autoincrementstart"/> </xsl:when> <xsl:otherwise> <xsl:value-of select="col_min_val + autoincrementinc"/> </xsl:otherwise> </xsl:choose> </xsl:when> </xsl:choose> </xsl:variable> <xsl:if test="not(position()=1)"><xsl:text> </xsl:text></xsl:if> <xsl:choose> <!--restart with ddl changes both the next identity value AUTOINCREMENTVALUE and the identity start number AUTOINCREMENTSTART eventhough in this casewe only want to change only the next identity number--> <xsl:when test="$newstart != '' and $newstart != autoincrementvalue">alter table <xsl:value-of select="$tablespec"/> alter column <xsl:value-of select="$col_name"/> restart with <xsl:value-of select="$newstart"/><xsl:if test="$identitycount>1">;</xsl:if></xsl:when> <xsl:otherwise>-- reseed <xsl:value-of select="$tablespec"/> is not necessary</xsl:otherwise> </xsl:choose> </xsl:for-each> </xsl:template> </xsl:stylesheet>

  • Python regex to parse text file, get the items in list and count the list

    - by Nemo
    I have a text file which contains some data. I m particularly interested in finding the count of the number of items in v_dims v_dims pattern in my text file looks like this : v_dims={ "Sales", "Product Family", "Sales Organization", "Region", "Sales Area", "Sales office", "Sales Division", "Sales Person", "Sales Channel", "Sales Order Type", "Sales Number", "Sales Person", "Sales Quantity", "Sales Amount" } So I m thinking of getting all the elements in v_dims and dumping them out in a Python list. Then compute the len(mylist) to get the count of the items. The challenge is in getting all the elements of v_dims from my text file and putting them in an empty list. I m particularly interested in items in v_dims in my text file. The text file has data in the form of v_dims pattern i showed in my original post. Some data has nested patterns of v_dims. Thanks. Here's what I have tried and failed. Any help is appreciated. TIA. import re fname = "C:\Users\XXXX\Test.mrk" with open(fname, "r") as fo: content_as_string = fo.read() match = re.findall(r'v_dims={\"(.+?)\"}',content_as_string) Though I have a big text file,

  • What pseudo-operators exist in Perl 5?

    - by Chas. Owens
    I am currently documenting all of Perl 5's operators (see the perlopref GitHub project) and I have decided to include Perl 5's pseudo-operators as well. To me, a pseudo-operator in Perl is anything that looks like an operator, but is really more than one operator or a some other piece of syntax. I have documented the four I am familiar with already: ()= the countof operator =()= the goatse/countof operator ~~ the scalar context operator }{ the Eskimo-kiss operator What other names exist for these pseudo-operators, and do you know of any pseudo-operators I have missed? =head1 Pseudo-operators There are idioms in Perl 5 that appear to be operators, but are really a combination of several operators or pieces of syntax. These pseudo-operators have the precedence of the constituent parts. =head2 ()= X =head3 Description This pseudo-operator is the list assignment operator (aka the countof operator). It is made up of two items C<()>, and C<=>. In scalar context it returns the number of items in the list X. In list context it returns an empty list. It is useful when you have something that returns a list and you want to know the number of items in that list and don't care about the list's contents. It is needed because the comma operator returns the last item in the sequence rather than the number of items in the sequence when it is placed in scalar context. It works because the assignment operator returns the number of items available to be assigned when its left hand side has list context. In the following example there are five values in the list being assigned to the list C<($x, $y, $z)>, so C<$count> is assigned C<5>. my $count = my ($x, $y, $z) = qw/a b c d e/; The empty list (the C<()> part of the pseudo-operator) triggers this behavior. =head3 Example sub f { return qw/a b c d e/ } my $count = ()= f(); #$count is now 5 my $string = "cat cat dog cat"; my $cats = ()= $string =~ /cat/g; #$cats is now 3 print scalar( ()= f() ), "\n"; #prints "5\n" =head3 See also L</X = Y> and L</X =()= Y> =head2 X =()= Y This pseudo-operator is often called the goatse operator for reasons better left unexamined; it is also called the list assignment or countof operator. It is made up of three items C<=>, C<()>, and C<=>. When X is a scalar variable, the number of items in the list Y is returned. If X is an array or a hash it it returns an empty list. It is useful when you have something that returns a list and you want to know the number of items in that list and don't care about the list's contents. It is needed because the comma operator returns the last item in the sequence rather than the number of items in the sequence when it is placed in scalar context. It works because the assignment operator returns the number of items available to be assigned when its left hand side has list context. In the following example there are five values in the list being assigned to the list C<($x, $y, $z)>, so C<$count> is assigned C<5>. my $count = my ($x, $y, $z) = qw/a b c d e/; The empty list (the C<()> part of the pseudo-operator) triggers this behavior. =head3 Example sub f { return qw/a b c d e/ } my $count =()= f(); #$count is now 5 my $string = "cat cat dog cat"; my $cats =()= $string =~ /cat/g; #$cats is now 3 =head3 See also L</=> and L</()=> =head2 ~~X =head3 Description This pseudo-operator is named the scalar context operator. It is made up of two bitwise negation operators. It provides scalar context to the expression X. It works because the first bitwise negation operator provides scalar context to X and performs a bitwise negation of the result; since the result of two bitwise negations is the original item, the value of the original expression is preserved. With the addition of the Smart match operator, this pseudo-operator is even more confusing. The C<scalar> function is much easier to understand and you are encouraged to use it instead. =head3 Example my @a = qw/a b c d/; print ~~@a, "\n"; #prints 4 =head3 See also L</~X>, L</X ~~ Y>, and L<perlfunc/scalar> =head2 X }{ Y =head3 Description This pseudo-operator is called the Eskimo-kiss operator because it looks like two faces touching noses. It is made up of an closing brace and an opening brace. It is used when using C<perl> as a command-line program with the C<-n> or C<-p> options. It has the effect of running X inside of the loop created by C<-n> or C<-p> and running Y at the end of the program. It works because the closing brace closes the loop created by C<-n> or C<-p> and the opening brace creates a new bare block that is closed by the loop's original ending. You can see this behavior by using the L<B::Deparse> module. Here is the command C<perl -ne 'print $_;'> deparsed: LINE: while (defined($_ = <ARGV>)) { print $_; } Notice how the original code was wrapped with the C<while> loop. Here is the deparsing of C<perl -ne '$count++ if /foo/; }{ print "$count\n"'>: LINE: while (defined($_ = <ARGV>)) { ++$count if /foo/; } { print "$count\n"; } Notice how the C<while> loop is closed by the closing brace we added and the opening brace starts a new bare block that is closed by the closing brace that was originally intended to close the C<while> loop. =head3 Example # count unique lines in the file FOO perl -nle '$seen{$_}++ }{ print "$_ => $seen{$_}" for keys %seen' FOO # sum all of the lines until the user types control-d perl -nle '$sum += $_ }{ print $sum' =head3 See also L<perlrun> and L<perlsyn> =cut

    Hi, I have to send the audio data in byte array obtain by recording from java applet at the client side to rails server at the controller in order to save.

  • Passing XML markers to Google Map

    - by djmadscribbler
    I've been creating a V3 Google map based on this example from Mike Williams http://www.geocodezip.com/v3_MW_example_map3.html I've run into a bit of a problem though. If I have no parameters in my URL then I get the error "id is undefined idmarkers [id.toLowerCase()] = marker;" in Firebug and only one marker will show up. If I have a parameter (?id=105 for example) then all the sidebar links say 105 (or whatever the parameter in the URL was) instead of their respective label as listed in the XML file and a random infowindow will be opened instead of the window for the id in the URL. Here is my javascript: var map = null; var lastmarker = null; // ========== Read paramaters that have been passed in ========== // Before we go looking for the passed parameters, set some defaults // in case there are no parameters var id; var index = -1; // these set the initial center, zoom and maptype for the map // if it is not specified in the query string var lat = 42.194741; var lng = -121.700301; var zoom = 18; var maptype = google.maps.MapTypeId.HYBRID;

break; default: case google.maps.MapTypeId.ROADMAP: urlValue = 'm'; break; } return urlValue; } // If there are any parameters at eh end of the URL, they will be in location.search // looking something like "?marker=3" // skip the first character, we are not interested in the "?" var query = location.search.substring(1); // split the rest at each "&" character to give a list of "argname=value" pairs var pairs = query.split("&"); for (var i = 0; i < pairs.length; i++) { // break each pair at the first "=" to obtain the argname and value var pos = pairs[i].indexOf("="); var argname = pairs[i].substring(0, pos).toLowerCase(); var value = pairs[i].substring(pos + 1).toLowerCase(); // process each possible argname - use unescape() if theres any chance of spaces if (argname == "id") { id = unescape(value);

  • storing session data in mysql using php is not retrieving the data properly from the tables.

    - by Ronedog
    I have a problem retrieving some data from the $_SESSION using php and mysql. I've commented out the line in php.ini that tells the server to use the "file" to store the session info so my database will be used. I have a class that I use to write the information to the database and its working fine. When the user passes their credentials the class gets instantiated and the $_SESSION vars get set, then the user gets redirected to the index page. The index.php page includes the file where the db session class is, which when instantiated calles session_start() and the session variables should be in $_SESSION, but when I do var_dump($_SESSION) there is nothing in the array. However, when I look at the data in mysql, all the session information is in there. Its acting like session_start() has not been called, but by instantiating the class it is. Any idea what could be wrong? Here's the HTML: <?php include_once "classes/phpsessions_db/class.dbsession.php"; //used for sessions var_dump($_SESSION); ?> <html> . . . </html> Here's the dbsession class: <?php error_reporting(E_ALL); class dbSession { function dbSession($gc_maxlifetime = "", $gc_probability = "", $gc_divisor = "") { // if $gc_maxlifetime is specified and is an integer number if ($gc_maxlifetime != "" && is_integer($gc_maxlifetime)) { // set the new value @ini_set('session.gc_maxlifetime', $gc_maxlifetime); } // if $gc_probability is specified and is an integer number if ($gc_probability != "" && is_integer($gc_probability)) { // set the new value @ini_set('session.gc_probability', $gc_probability); } // if $gc_divisor is specified and is an integer number if ($gc_divisor != "" && is_integer($gc_divisor)) { // set the new value @ini_set('session.gc_divisor', $gc_divisor); } // get session lifetime $this->sessionLifetime = ini_get("session.gc_maxlifetime"); //Added by AARON. cancel the session's auto start,important, without this the session var's don't show up on next pg. session_write_close(); // register the new handler session_set_save_handler( array(&$this, 'open'), array(&$this, 'close'), array(&$this, 'read'), array(&$this, 'write'), array(&$this, 'destroy'), array(&$this, 'gc') ); register_shutdown_function('session_write_close'); // start the session @session_start(); } function stop() { $new_sess_id = $this->regenerate_id(true); session_unset(); session_destroy(); return $new_sess_id; } function regenerate_id($return_val=false) { // saves the old session's id $oldSessionID = session_id(); // regenerates the id // this function will create a new session, with a new id and containing the data from the old session // but will not delete the old session session_regenerate_id(); // because the session_regenerate_id() function does not delete the old session, // we have to delete it manually //$this->destroy($oldSessionID); //ADDED by aaron // returns the new session id if($return_val) { return session_id(); } } function open($save_path, $session_name) { // global $gf; // $gf->debug_this($gf, "GF: Opening Session"); // change the next values to match the setting of your mySQL database $mySQLHost = "localhost"; $mySQLUsername = "user"; $mySQLPassword = "pass"; $mySQLDatabase = "sessions"; $link = mysql_connect($mySQLHost, $mySQLUsername, $mySQLPassword); if (!$link) { die ("Could not connect to database!"); } $dbc = mysql_select_db($mySQLDatabase, $link); if (!$dbc) { die ("Could not select database!"); } return true; } function close() { mysql_close(); return true; } function read($session_id) { $result = @mysql_query(" SELECT session_data FROM session_data WHERE session_id = '".$session_id."'

  • Questions related to writing your own file downloader using multiple threads java

    - by Shekhar
    Hello In my current company, i am doing a PoC on how we can write a file downloader utility. We have to use socket programming(TCP/IP) for downloading the files. One of the requirements of the client is that a file(which will be large in size) should be transfered in chunks for example if we have a file of 5Mb size then we can have 5 threads which transfer 1 Mb each. I have written a small application which downloads a file. You can download the eclipe project from http://www.fileflyer.com/view/QM1JSC0 A brief explanation of my classes FileSender.java This class provides the bytes of file. It has a method called sendBytesOfFile(long start,long end, long sequenceNo) which gives the number of bytes. import java.io.File; import java.io.IOException; import java.util.zip.CRC32; import org.apache.commons.io.FileUtils; public class FileSender { private static final String FILE_NAME = "C:\\shared\\test.pdf"; public ByteArrayWrapper sendBytesOfFile(long start,long end, long sequenceNo){ try { File file = new File(FILE_NAME); byte[] fileBytes = FileUtils.readFileToByteArray(file); System.out.println("Size of file is " +fileBytes.length); System.out.println(); System.out.println("Start "+start +" end "+end); byte[] bytes = getByteArray(fileBytes, start, end); ByteArrayWrapper wrapper = new ByteArrayWrapper(bytes, sequenceNo); return wrapper; } catch (IOException e) { throw new RuntimeException(e); } } private byte[] getByteArray(byte[] bytes, long start, long end){ long arrayLength = end-start; System.out.println("Start : "+start +" end : "+end + " Arraylength : "+arrayLength +" length of source array : "+bytes.length); byte[] arr = new byte[(int)arrayLength]; for(int i = (int)start, j =0; i < end;i++,j++){ arr[j] = bytes[i]; } return arr; } public static long fileSize(){ File file = new File(FILE_NAME); return file.length(); } } Second Class is FileReceiver.java - This class receives the file. Small Explanation what this file does This class finds the size of the file to be fetched from Sender Depending upon the size of the file it finds the start and end position till the bytes needs to be read. It starts n number of threads giving each thread start,end, sequence number and a list which all the threads share. Each thread reads the number of bytes and creates a ByteArrayWrapper. ByteArrayWrapper objects are added to the list Then i have while loop which basically make sure that all threads have done their work finally it sorts the list based on the sequence number. then the bytes are joined, and a complete byte array is formed which is converted to a file. Code of File Receiver package com.filedownloader; import java.io.File; import java.io.IOException; import java.util.ArrayList; import java.util.Collections; import java.util.Comparator; import java.util.List; import java.util.zip.CRC32; import org.apache.commons.io.FileUtils; public class FileReceiver { public static void main(String[] args) { FileReceiver receiver = new FileReceiver(); receiver.receiveFile(); } public void receiveFile(){ long startTime = System.currentTimeMillis(); long numberOfThreads = 10; long filesize = FileSender.fileSize(); System.out.println("File size received "+filesize); long start = filesize/numberOfThreads; List<ByteArrayWrapper> list = new ArrayList<ByteArrayWrapper>(); for(long threadCount =0; threadCount<numberOfThreads ;threadCount++){ FileDownloaderTask task = new FileDownloaderTask(threadCount*start,(threadCount+1)*start,threadCount,list); new Thread(task).start(); } while(list.size() != numberOfThreads){ // this is done so that all the threads should complete their work before processing further. //System.out.println("Waiting for threads to complete. List size "+list.size()); } if(list.size() == numberOfThreads){ System.out.println("All bytes received "+list); Collections.sort(list, new Comparator<ByteArrayWrapper>() { @Override public int compare(ByteArrayWrapper o1, ByteArrayWrapper o2) { long sequence1 = o1.getSequence(); long sequence2 = o2.getSequence(); if(sequence1 < sequence2){ return -1; }else if(sequence1 > sequence2){ return 1; } else{ return 0; } } }); byte[] totalBytes = list.get(0).getBytes(); byte[] firstArr = null; byte[] secondArr = null; for(int i = 1;i<list.size();i++){ firstArr = totalBytes; secondArr = list.get(i).getBytes(); totalBytes = concat(firstArr, secondArr); } System.out.println(totalBytes.length); convertToFile(totalBytes,"c:\\tmp\\test.pdf"); long endTime = System.currentTimeMillis(); System.out.println("Total time taken with "+numberOfThreads +" threads is "+(endTime-startTime)+" ms" ); } } private byte[] concat(byte[] A, byte[] B) { byte[] C= new byte[A.length+B.length]; System.arraycopy(A, 0, C, 0, A.length); System.arraycopy(B, 0, C, A.length, B.length); return C; } private void convertToFile(byte[] totalBytes,String name) { try { FileUtils.writeByteArrayToFile(new File(name), totalBytes); } catch (IOException e) { throw new RuntimeException(e); } } } Code of ByteArrayWrapper package com.filedownloader; import java.io.Serializable; public class ByteArrayWrapper implements Serializable{ private static final long serialVersionUID = 3499562855188457886L; private byte[] bytes; private long sequence; public ByteArrayWrapper(byte[] bytes, long sequenceNo) { this.bytes = bytes; this.sequence = sequenceNo; } public byte[] getBytes() { return bytes; } public long getSequence() { return sequence; } } Code of FileDownloaderTask import java.util.List; public class FileDownloaderTask implements Runnable { private List<ByteArrayWrapper> list; private long start; private long end; private long sequenceNo; public FileDownloaderTask(long start,long end,long sequenceNo,List<ByteArrayWrapper> list) { this.list = list; this.start = start; this.end = end; this.sequenceNo = sequenceNo; } @Override public void run() { ByteArrayWrapper wrapper = new FileSender().sendBytesOfFile(start, end, sequenceNo); list.add(wrapper); } } Questions related to this code 1) Does file downloading becomes fast when multiple threads is used? In this code i am not able to see the benefit. 2) How should i decide how many threads should i create ? 3) Are their any opensource libraries which does that 4) The file which file receiver receives is valid and not corrupted but checksum (i used FileUtils of common-io) does not match. Whats the problem? 5) This code gives out of memory when used with large file(above 100 Mb) i.e. because byte array which is created. How can i avoid? I know this is a very bad code but i have to write this in one day -:). Please suggest any other good way to do this? Thanks Shekhar

  • c++ stl priority queue insert bad_alloc exception

    - by bsg
    Hi, I am working on a query processor that reads in long lists of document id's from memory and looks for matching id's. When it finds one, it creates a DOC struct containing the docid (an int) and the document's rank (a double) and pushes it on to a priority queue. My problem is that when the word(s) searched for has a long list, when I try to push the DOC on to the queue, I get the following exception: Unhandled exception at 0x7c812afb in QueryProcessor.exe: Microsoft C++ exception: std::bad_alloc at memory location 0x0012ee88.. When the word has a short list, it works fine. I tried pushing DOC's onto the queue in several places in my code, and they all work until a certain line; after that, I get the above error. I am completely at a loss as to what is wrong because the longest list read in is less than 1 MB and I free all memory that I allocate. Why should there suddenly be a bad_alloc exception when I try to push a DOC onto a queue that has a capacity to hold it (I used a vector with enough space reserved as the underlying data structure for the priority queue)? I know that questions like this are almost impossible to answer without seeing all the code, but it's too long to post here. I'm putting as much as I can and am anxiously hoping that someone can give me an answer, because I am at my wits' end. The NextGEQ function is too long to put here, but it reads a list of compressed blocks of docids block by block. That is, if it sees that the lastdocid in the block (in a separate list) is larger than the docid passed in, it decompresses the block and searches until it finds the right one. If it sees that it was already decompressed, it just searches. Below, when I call the function the first time, it decompresses a block and finds the docid; the push onto the queue after that works. The second time, it doesn't even need to decompress; that is, no new memory is allocated, but after that time, pushing on to the queue gives a bad_alloc error. struct DOC{ long int docid; long double rank; public: DOC() { docid = 0; rank = 0.0; } DOC(int num, double ranking) { docid = num; rank = ranking; } bool operator>( const DOC & d ) const { return rank > d.rank; } bool operator<( const DOC & d ) const { return rank < d.rank; } }; struct listnode{ int* metapointer; int* blockpointer; int docposition; int frequency; int numberdocs; int* iquery; listnode* nextnode; }; void QUERYMANAGER::SubmitQuery(char *query){ vector<DOC> docvec; docvec.reserve(20); DOC doct; //create a priority queue to use as a min-heap to store the documents and rankings; //although the priority queue uses the heap as its underlying data structure, //I found it easier to use the STL priority queue implementation priority_queue<DOC, vector<DOC>,std::greater<DOC>> q(docvec.begin(), docvec.end()); q.push(doct); //do some processing here; startlist is a pointer to a listnode struct that starts the //linked list cout << "Opening lists:" << endl; //point the linked list start pointer to the node returned by the OpenList method startlist = &OpenList(value); listnode* minpointer; q.push(doct); //more processing here; else{ //start by finding the first docid in the shortest list int i = 0; q.push(doct); num = NextGEQ(0, *startlist); q.push(doct); while(num != -1) cout << "finding nextGEQ from shortest list" << endl; q.push(doct); //the is where the problem starts - every previous q.push(doct) works; the one after //NextGEQ(num +1, *startlist) gives the bad_alloc error num = NextGEQ(num + 1, *startlist); q.push(doct); //if you didn't break out of the loop; i.e., all lists contain a matching docid, //calculate the document's rank; if it's one of the top 20, create a struct //containing the docid and the rank and add it to the priority queue if(!loop) { cout << "found match" << endl; if(num < 0) { cout << "reached end of list" << endl; //reached the end of the shortest list; close the list CloseList(startlist); break; } rank = calculateRanking(table, num); try{ //if the heap is not full, create a DOC struct with the docid and //rank and add it to the heap if(q.size() < 20) { doc.docid = num; doc.rank = rank; q.push(doct); q.push(doc); } } catch (exception& e) { cout << e.what() << endl; } } } Thank you very much, bsg.

  • PHP inserting Apostrophes where it shouldn't

    - by Jack W-H
    Hi folks Not too sure what's going on here as this doesn't seem like standard practise to me. But basically I have a basic database thingy going on that lets users submit code snippets. They can provide up to 5 tags for their submission. Now I'm still learning so please forgive me if this is obvious! Here's the PHP script that makes it all work (note there may be some CodeIgniter specific functions in there): function submitform() { $this->load->helper(array('form', 'url')); $this->load->library('form_validation'); $this->load->database(); $this->form_validation->set_error_delimiters('<p style="color:#FF0000;">', '</p>'); $this->form_validation->set_rules('title', 'Title', 'trim|required|min_length[5]|max_length[255]|xss_clean'); $this->form_validation->set_rules('summary', 'Summary', 'trim|required|min_length[5]|max_length[255]|xss_clean'); $this->form_validation->set_rules('bbcode', 'Code', 'required|min_length[5]'); // No XSS clean (or <script> tags etc. are gone) $this->form_validation->set_rules('tags', 'Tags', 'trim|xss_clean|required|max_length[254]'); if ($this->form_validation->run() == FALSE) { // Do some stuff if it fails } else { // User's input values $title = $this->db->escape(set_value('title')); $summary = $this->db->escape(set_value('summary')); $code = $this->db->escape(set_value('bbcode')); $tags = $this->db->escape(set_value('tags')); // Stop things like <script> tags working $codesanitised = htmlspecialchars($code); // Other values to be entered $author = $this->tank_auth->get_user_id(); $bi1 = ""; $bi2 = ""; // This long messy bit basically sees which browsers the code is compatible with. if (isset($_POST['IE6'])) {$bi1 .= "IE6, "; $bi2 .= "1, ";} else {$bi1 .= "IE6, "; $bi2 .= "NULL, ";} if (isset($_POST['IE7'])) {$bi1 .= "IE7, "; $bi2 .= "1, ";} else {$bi1 .= "IE7, "; $bi2 .= "NULL, ";} if (isset($_POST['IE8'])) {$bi1 .= "IE8, "; $bi2 .= "1, ";} else {$bi1 .= "IE8, "; $bi2 .= "NULL, ";} if (isset($_POST['FF2'])) {$bi1 .= "FF2, "; $bi2 .= "1, ";} else {$bi1 .= "FF2, "; $bi2 .= "NULL, ";} if (isset($_POST['FF3'])) {$bi1 .= "FF3, "; $bi2 .= "1, ";} else {$bi1 .= "FF3, "; $bi2 .= "NULL, ";} if (isset($_POST['SA3'])) {$bi1 .= "SA3, "; $bi2 .= "1, ";} else {$bi1 .= "SA3, "; $bi2 .= "NULL, ";} if (isset($_POST['SA4'])) {$bi1 .= "SA4, "; $bi2 .= "1, ";} else {$bi1 .= "SA4, "; $bi2 .= "NULL, ";} if (isset($_POST['CHR'])) {$bi1 .= "CHR, "; $bi2 .= "1, ";} else {$bi1 .= "CHR, "; $bi2 .= "NULL, ";} if (isset($_POST['OPE'])) {$bi1 .= "OPE, "; $bi2 .= "1, ";} else {$bi1 .= "OPE, "; $bi2 .= "NULL, ";} if (isset($_POST['OTH'])) {$bi1 .= "OTH, "; $bi2 .= "1, ";} else {$bi1 .= "OTH, "; $bi2 .= "NULL, ";} // $b1 is $bi1 without the last two characters (, ) which would cause a query error $b1 = substr($bi1, 0, -2); $b2 = substr($bi2, 0, -2); // :::::::::::THIS IS WHERE THE IMPORTANT STUFF IS, STACKOVERFLOW READERS:::::::::: // Split up all the words in $tags into individual variables - each tag is seperated with a space $pieces = explode(" ", $tags); // Usage: // echo $pieces[0]; // piece1 etc $ti1 = ""; $ti2 = ""; // Now we'll do similar to what we did with the compatible browsers to generate a bit of a query string if ($pieces[0]!=NULL) {$ti1 .= "tag1, "; $ti2 .= "$pieces[0], ";} else {$ti1 .= "tag1, "; $ti2 .= "NULL, ";} if ($pieces[1]!=NULL) {$ti1 .= "tag2, "; $ti2 .= "$pieces[1], ";} else {$ti1 .= "tag2, "; $ti2 .= "NULL, ";} if ($pieces[2]!=NULL) {$ti1 .= "tag3, "; $ti2 .= "$pieces[2], ";} else {$ti1 .= "tag3, "; $ti2 .= "NULL, ";} if ($pieces[3]!=NULL) {$ti1 .= "tag4, "; $ti2 .= "$pieces[3], ";} else {$ti1 .= "tag4, "; $ti2 .= "NULL, ";} if ($pieces[4]!=NULL) {$ti1 .= "tag5, "; $ti2 .= "$pieces[4], ";} else {$ti1 .= "tag5, "; $ti2 .= "NULL, ";} $t1 = substr($ti1, 0, -2); $t2 = substr($ti2, 0, -2); $sql = "INSERT INTO code (id, title, author, summary, code, date, $t1, $b1) VALUES ('', $title, $author, $summary, $codesanitised, NOW(), $t2, $b2)"; $this->db->query($sql); $this->load->view('subviews/template/headerview'); $this->load->view('subviews/template/menuview'); $this->load->view('subviews/template/sidebar'); $this->load->view('thanksforsubmission'); $this->load->view('subviews/template/footerview'); } } Sorry about that boring drivel of code there. I realise I probably have a few bad practises in there - please point them out if so. This is what the outputted query looks like (it results in an error and isn't queried at all): A Database Error Occurred Error Number: 1136 Column count doesn't match value count at row 1 INSERT INTO code (id, title, author, summary, code, date, tag1, tag2, tag3, tag4, tag5, IE6, IE7, IE8, FF2, FF3, SA3, SA4, CHR, OPE, OTH) VALUES ('', 'test2', 1, 'test2', 'test2 ', NOW(), 'test2, test2, test2, test2, test2', NULL, NULL, 1, 1, 1, 1, 1, 1, 1, NULL) You'll see at the bit after NOW(), 'test2, test2, test2, test2, test2' - I never asked it to put all that in apostrophes. Did I? What I could do is put each of those lines like this: if ($pieces[0]!=NULL) {$ti1 .= "tag1, "; $ti2 .= "'$pieces[0]', ";} else {$ti1 .= "tag1, "; $ti2 .= "NULL, ";} With single quotes around $pieces[0] etc. - but then my problem is that this kinda fails when the user only enters 4 tags, or 3, or whatever. Sorry if that's the worst phrased question in history, I tried, but my brain has turned to mush. Thanks for your help! Jack
