    I am new to ASP.NET MVC 2. I do not understand why I am receiving this error. Is there something missing that i'm not referencing correctly. I'm trying to create a simple jquery autocomplete online search textbox and view the details of the person that i select using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using System.Web.Mvc.Ajax; using DOC_Kools.Models; namespace DOC_Kools.Controllers { public class HomeController : Controller { private KOOLSEntities _dataModel = new KOOLSEntities(); // // GET: /Home/ public ActionResult Index() { ViewData["Message"] = "Welcome to ASP.NET MVC!"; return View(); } // // GET: /Home/ public ActionResult getAjaxResult(string q) { string searchResult = string.Empty; var offenders = (from o in _dataModel.OffenderSet where o.LastName.Contains(q) orderby o.LastName select o).Take(10); foreach (Offender o in offenders) { searchResult += string.Format("{0}|r\n", o.LastName); } return Content(searchResult); } [AcceptVerbs(HttpVerbs.Post)] public ActionResult Search(string searchTerm) { if (searchTerm == string.Empty) { return View(); } else { // if the search contains only one result return detials // otherwise a list var offenders = from o in _dataModel.OffenderSet where o.LastName.Contains(searchTerm) orderby o.LastName select o; if (offenders.Count() == 0) { return View("not found"); } if (offenders.Count() > 1) { return View("List", offenders); } else { return RedirectToAction("Details", new { id = offenders.First().SPN }); } } } // // GET: /Home/Details/5 public ActionResult Details(int id) { return View(); } // // GET: /Home/Create public ActionResult Create() { return View(); } // // POST: /Home/Create [AcceptVerbs(HttpVerbs.Post)] public ActionResult Create(FormCollection collection) { try { // TODO: Add insert logic here return RedirectToAction("Index"); } catch { return View(); } } // // GET: /Home/Edit/5 public ActionResult Edit(int id) { return View(); } // // POST: /Home/Edit/5 [AcceptVerbs(HttpVerbs.Post)] public ActionResult Edit(int id, FormCollection collection) { try { // TODO: Add update logic here return RedirectToAction("Index"); } catch { return View(); } } public ActionResult About() { return View(); } } } using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using System.Web.Routing; namespace DOC_Kools { // Note: For instructions on enabling IIS6 or IIS7 classic mode, // visit http://go.microsoft.com/?LinkId=9394801 public class MvcApplication : System.Web.HttpApplication { public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = "" } // Parameter defaults ); routes.MapRoute( "OffenderSearch", "Offenders/Search/{searchTerm}", new { controller = "Home", action = "Index", searchTerm = "" } ); routes.MapRoute( "OffenderAjaxSearch", "Offenders/getAjaxResult/", new { controller = "Home", action = "getAjaxResult" } ); } protected void Application_Start() { AreaRegistration.RegisterAllAreas(); RegisterRoutes(RouteTable.Routes); } } } <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<DOC_Kools.Models.Offender>" %> $(document).ready(function() { $("#searchTerm").autocomplete("/Offenders/getAjaxResult/"); }); Home Page <%= Html.Encode(ViewData["Message"]) % <h2>Look for an offender</h2> <form action="/Offenders/Search" method="post" id="searchForm"> <input type="text" name="searchTerm" id="searchTerm" value="" size="10" maxlength="30" /> <input type="submit" value="Search" /> </form> <br /> what do i have to do in order for the textbox search to display on the index page?

  • Migrate from MySQL to PostgreSQL on Linux (Kubuntu)

    - by Dave Jarvis
    A long time ago in a galaxy far, far away... Trying to migrate a database from MySQL to PostgreSQL. All the documentation I have read covers, in great detail, how to migrate the structure. I have found very little documentation on migrating the data. The schema has 13 tables (which have been migrated successfully) and 9 GB of data. MySQL version: 5.1.x PostgreSQL version: 8.4.x I want to use the R programming language to analyze the data using SQL select statements; PostgreSQL has PL/R, but MySQL has nothing (as far as I can tell). A New Hope Create the database location (/var has insufficient space; also dislike having the PostgreSQL version number everywhere -- upgrading would break scripts!): sudo mkdir -p /home/postgres/main sudo cp -Rp /var/lib/postgresql/8.4/main /home/postgres sudo chown -R postgres.postgres /home/postgres sudo chmod -R 700 /home/postgres sudo usermod -d /home/postgres/ postgres All good to here. Next, restart the server and configure the database using these installation instructions: sudo apt-get install postgresql pgadmin3 sudo /etc/init.d/postgresql-8.4 stop sudo vi /etc/postgresql/8.4/main/postgresql.conf Change data_directory to /home/postgres/main sudo /etc/init.d/postgresql-8.4 start sudo -u postgres psql postgres \password postgres sudo -u postgres createdb climate pgadmin3 Use pgadmin3 to configure the database and create a schema. The episode continues in a remote shell known as bash, with both databases running, and the installation of a set of tools with a rather unusual logo: SQL Fairy. perl Makefile.PL sudo make install sudo apt-get install perl-doc (strangely, it is not called perldoc) perldoc SQL::Translator::Manual Extract a PostgreSQL-friendly DDL and all the MySQL data: sqlt -f DBI --dsn dbi:mysql:climate --db-user user --db-password password -t PostgreSQL > climate-pg-ddl.sql mysqldump --skip-add-locks --complete-insert --no-create-db --no-create-info --quick --result-file="climate-my.sql" --databases climate --skip-comments -u root -p The Database Strikes Back Recreate the structure in PostgreSQL as follows: pgadmin3 (switch to it) Click the Execute arbitrary SQL queries icon Open climate-pg-ddl.sql Search for TABLE " replace with TABLE climate." (insert the schema name climate) Search for on " replace with on climate." (insert the schema name climate) Press F5 to execute This results in: Query returned successfully with no result in 122 ms. Replies of the Jedi At this point I am stumped. Where do I go from here (what are the steps) to convert climate-my.sql to climate-pg.sql so that they can be executed against PostgreSQL? How to I make sure the indexes are copied over correctly (to maintain referential integrity; I don't have constraints at the moment to ease the transition)? How do I ensure that adding new rows in PostgreSQL will start enumerating from the index of the last row inserted (and not conflict with an existing primary key from the sequence)? How do you ensure the schema name comes through when transforming the data from MySQL to PostgreSQL inserts? Resources A fair bit of information was needed to get this far: https://help.ubuntu.com/community/PostgreSQL http://articles.sitepoint.com/article/site-mysql-postgresql-1 http://wiki.postgresql.org/wiki/Converting_from_other_Databases_to_PostgreSQL#MySQL http://pgfoundry.org/frs/shownotes.php?release_id=810 http://sqlfairy.sourceforge.net/ Thank you!

  • Mac 10.6 Universal Binary scipy: cephes/specfun "_aswfa_" symbol not found

    - by Markus
    Hi folks, I can't get scipy to function in 32 bit mode when compiled as a i386/x86_64 universal binary, and executed on my 64 bit 10.6.2 MacPro1,1. My python setup With the help of this answer, I built a 32/64 bit intel universal binary of python 2.6.4 with the intention of using the arch command to select between the architectures. (I managed to make some universal binaries of a few libraries I wanted using lipo.) That all works. I then installed scipy according to the instructions on hyperjeff's article, only with more up-to-date numpy (1.4.0) and skipping the bit about moving numpy aside briefly during the installation of scipy. Now, everything except scipy seems to be working as far as I can tell, and I can indeed select between 32 and 64 bit mode using arch -i386 python and arch -x86_64 python. The error Scipy complains in 32 bit mode: $ arch -x86_64 python -c "import scipy.interpolate; print 'success'" success $ arch -i386 python -c "import scipy.interpolate; print 'success'" Traceback (most recent call last): File "<string>", line 1, in <module> File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/interpolate/__init__.py", line 7, in <module> from interpolate import * File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/interpolate/interpolate.py", line 13, in <module> import scipy.special as spec File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/special/__init__.py", line 8, in <module> from basic import * File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/special/basic.py", line 8, in <module> from _cephes import * ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/special/_cephes.so, 2): Symbol not found: _aswfa_ Referenced from: /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/special/_cephes.so Expected in: flat namespace in /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/special/_cephes.so Attempt at tracking down the problem It looks like scipy.interpolate imports something called _cephes, which looks for a symbol called _aswfa_ but can't find it in 32 bit mode. Browsing through scipy's source, I find an ASWFA subroutine in specfun.f. The only scipy product file with a similar name is specfun.so, but both that and _cephes.so appear to be universal binaries: $ cd /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/special/ $ file _cephes.so specfun.so _cephes.so: Mach-O universal binary with 2 architectures _cephes.so (for architecture i386): Mach-O bundle i386 _cephes.so (for architecture x86_64): Mach-O 64-bit bundle x86_64 specfun.so: Mach-O universal binary with 2 architectures specfun.so (for architecture i386): Mach-O bundle i386 specfun.so (for architecture x86_64): Mach-O 64-bit bundle x86_64 Ho hum. I'm stuck. Things I may try but haven't figured out how yet include compiling specfun.so myself manually, somehow. I would imagine that scipy isn't broken for all 32 bit machines, so I guess something is wrong with the way I've installed it, but I can't figure out what. I don't really expect a full answer given my fairly unique (?) setup, but if anyone has any clues that might point me in the right direction, they'd be greatly appreciated. (edit) More details to address questions: I'm using gfortran (GNU Fortran from GCC 4.2.1 Apple Inc. build 5646). Python 2.6.4 was installed more-or-less like so: cd /tmp curl -O http://www.python.org/ftp/python/2.6.4/Python-2.6.4.tar.bz2 tar xf Python-2.6.4.tar.bz2 cd Python-2.6.4 # Now replace buggy pythonw.c file with one that supports the "arch" command: curl http://bugs.python.org/file14949/pythonw.c | sed s/2.7/2.6/ > Mac/Tools/pythonw.c ./configure --enable-framework=/Library/Frameworks --enable-universalsdk=/ --with-universal-archs=intel make -j4 sudo make frameworkinstall Scipy 0.7.1 was installed pretty much as described as here, but it boils down to a simple sudo python setup.py install. It would indeed appear that the symbol is undefined in the i386 architecture if you look at the _cephes library with nm, as suggested by David Cournapeau: $ nm -arch x86_64 /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/special/_cephes.so | grep _aswfa_ 00000000000d4950 T _aswfa_ 000000000011e4b0 d _oblate_aswfa_data 000000000011e510 d _oblate_aswfa_nocv_data (snip) $ nm -arch i386 /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/special/_cephes.so | grep _aswfa_ U _aswfa_ 0002e96c d _oblate_aswfa_data 0002e99c d _oblate_aswfa_nocv_data (snip) however, I can't yet explain its absence.

  • Get information about AutocompleteTextView from resulting AutoCompleteTextView$DropDownListView

    - by Stev_k
    I'm using 3 AutocompleteTextViews to suggest entries from a database. I subclassed AutocompleteTextView to handle setting the default text to null when clicked and setting back to the default instructions if moved away and nothing is entered. I was using a SimpleCursorAdapter to bind to the view, but I discovered that there was no way I could get the id of the AutocompleteTextView from an OnItemClickListener, which I needed to put additional information from the selected row in a variable depending on which AutocompleteTextView it was from. All I could access was the AutoCompleteTextView$DropDownListView, which is an undocumented inner class that appears to offer no real functionality. Neither was there a way to go up the view hierarchy to get the original AutocompleteTextView. So I subclassed SimpleCursorAdapter and added an int to the constructor to identify which AutocompleteTextView the adapter was from, and I was able to access this from the view passed into OnItemClick(). So, although my solution works fine, I wonder if it is possible to get the id of an AutocompleteTextView from its DropDownListView? I am also using another database query which gets the id from the OnItemClick and then looks up the data for that item, because I couldn't find a way of converting more than one column to a string. Should I be using CursorAdapter for this, to save initiating another query? Oh, and another thing, do I need a database cursor initially (all_cursor) when all I'm doing is filtering on it to get a new cursor? Seems like overkill. Activity .... dbse.openDataBase(); Cursor all_Cursor = dbse.autocomplete_query(); startManagingCursor(all_Cursor); String[] from_all = new String[]{DbAdapter.KEY_NAME}; int[] to_all = new int[] {android.R.id.text1}; from_adapt = new AutocompleteAdapter(FROM_DBADAPTER, this,android.R.layout.simple_dropdown_item_1line, all_Cursor, from_all, to_all); from_adapt.setStringConversionColumn(1); from_adapt.setFilterQueryProvider(this); to_adapt = new AutocompleteAdapter(TO_DBADAPTER, this,android.R.layout.simple_dropdown_item_1line, all_Cursor, from_all, to_all); to_adapt.setStringConversionColumn(1); to_adapt.setFilterQueryProvider(this); from_auto_complete = (Autocomplete) findViewById(R.id.entry_from); from_auto_complete.setAdapter(from_adapt); from_auto_complete.setOnItemClickListener(this); to_auto_complete = (Autocomplete) findViewById(R.id.entry_to); to_auto_complete.setAdapter(to_adapt); to_auto_complete.setOnItemClickListener(this); public void onItemClick (AdapterView<?> parent, View view, int position, long id) { Cursor selected_row_cursor = dbse.data_from_id(id); selected_row_cursor.moveToFirst(); String lat = selected_row_cursor.getString(1); String lon = selected_row_cursor.getString(2); int source = ((AutocompleteAdapter) parent.getAdapter()).getSource(); Autocomplete class: public class Autocomplete extends AutoCompleteTextView implements OnTouchListener,OnFocusChangeListener{ String textcontent; Context mycontext = null; int viewid = this.getId(); public Autocomplete(Context context, AttributeSet attrs) { super(context, attrs); textcontent = this.getText().toString(); mycontext = context; this.setOnFocusChangeListener(this); this.setOnTouchListener(this); } public boolean onTouch(View v, MotionEvent event) { if (textcontent.equals(mycontext.getString(R.string.from_textbox)) | textcontent.equals(mycontext.getString(R.string.to_textbox)) | textcontent.equals(mycontext.getString(R.string.via_textbox))) { this.setText(""); } return false; } public void onFocusChange(View v, boolean hasFocus) { if (hasFocus == false) { int a = this.getText().length(); if (a == 0){ if (viewid == R.id.entry_from) {this.setText(R.string.from_textbox);} if (viewid == R.id.entry_to) {this.setText(R.string.to_textbox);} if (viewid == R.id.entry_via) {this.setText(R.string.via_textbox);} } } } } Adapter: public class AutocompleteAdapter extends SimpleCursorAdapter { int source; public AutocompleteAdapter(int query_source, Context context, int layout, Cursor c, String[] from, int[] to) { super(context, layout, c, from, to); source = query_source; } public int getSource() { return source; } } sorry that's a lot of code! Thanks for your help. Stephen

  • Example map-reduce oozie program not working on CDH 4.5

    - by user2002748
    I am using Hadoop (CDH 4.5) on my mac since some time now, and do run map reduce jobs regularly. I installed oozie recently (again, CDH4.5) following instructions at: http://archive.cloudera.com/cdh4/cdh/4/oozie-3.3.2-cdh4.5.0/DG_QuickStart.html, and tried to run sample programs provided. However, it always fails with the following error. Looks like the workflow is not getting run at all. The Console URL field in the Job info is also empty. Could someone please help on this?

  • Hyper-V File Server Clustering - at my wit’s end

    - by René Kåbis
    I am at my wit’s end with File Server clustering under Hyper-V. I am hoping that someone might be able to help me figure out this Gordian Knot of a technology that seems to have dead ends (like forcing cluster VMs to use iSCSI drives where normally-attached VHDX drives could suffice) where logic and reason would normally provide a logical solution. My hardware: I will be running three servers (in the end), but right now everything is taking place on one server. One of the secondary servers will exist purely as a witness/quorum, and another slightly more powerful one will be acting as an emergency backup (with additional storage, just not redundant) to hold the secondary AD VM and the other halves of a set of clustered VMs: the SQL VM and the file system VM. Please note, these each are the depreciated nodes of a cluster, the main nodes will be on the most powerful first machine. My heavy lifter is a machine that also contains all of the truly redundant storage on the network. If this gives anyone the heebie-geebies, too bad. It has a 6TB (usable) RAID-10 array, and will (in the end) hold the primary nodes of both aforementioned clusters, but is right now holding all VMs. This is, right now: DC01, DC02, SQL01, SQL02, FS01 & FS02. Eventually, I will be adding additional VMs to handle Exchange, Sharepoint and Lync, but only to this main server (the secondary server won't be able to handle more than three or four VMs, so why burden it? The AD, SQL & FS VMs are the most critical for the business). If anyone is now saying, “wait, what about a SAN or a NAS for the file servers?”, well too bad. What exists on the main machine is what I have to deal with. I followed these instructions, but I seem to be unable to get things to work. In order to make the file server truly redundant, I cannot trust any one machine to hold the only data store on the network. Therefore, I have created a set of iSCSI drives on the VM-host of the main machine, and attached one to each file server VM. The end result is that I want my FS01 to sit on the heavy lifter, along with its iSCSI “drive”, and FS02 will sit on the secondary machine with its own iSCSI “drive” there as well. That is, neither iSCSI drive will end up sitting on the same machine as the other. As such, the clustered FS will utterly duplicate the contents of the iSCSI drives between each other, so that if one physical machine (or the FS VM) goes toes-up, the other has got a full copy of the data on its own iSCSI drive. My problem occurs when I try to apply the file server role within the failover cluster manager. Actually, it is even before that -- it occurs when adding the disks. Since I have added each disk preferentially to a specific VM (by limiting the initiator by DNS hostname, and by adding two-way CHAP authentication), this forces each VM to be in control of its own iSCSI disk. However, when I try to add the disks to the Disks section of Storage within Failover Cluster Manager, the entire process fails for a random disk of the pair. That is, one will get online, but the other will remain offline because it does not have the correct “owner node”. I mean, really -- WTF? Of course it doesn’t have the right owner node, both drives are showing the same node name!! I cannot seem to have one drive show up with one node name as owner, and the other drive show up with the other node name as owner. And because both drives are not “online”, I cannot create a pool to apply to a cluster role. Talk about getting stuck between a rock and a hard place! I’ve got more to add, but my work is closing for the day and I have to wrap things up. I will try to add more tomorrow morning when I get in. My main objective is to have a file server VM on each machine, the storage on each machine, but a transparent failover in case one physical machine fails. Essentially, a failover FS that doesn’t care which machine fails -- the storage contents are replicated equally on each machine. Am I even heading in the right direction?

  • Cross Compiling Boost for use on the Gumstix Overo with GumROS

    - by amelim
    I'm trying to cross-compile boost for use with the ROS framework on a Gumstix Overo. I've been following the posted instructions here (modifying the script when need be), however I've come across an issue where bjam will not compile boost properly. I call bjam as follows: # boost if [ ! -f /opt/gumros/lib/libboost_date_time-gcc41-mt-1_38.so ] ; then if [ ! -f boost_1_38_0.tar.gz ] ; then wget --tries=10 http://heanet.dl.sourceforge.net/sourceforge/boost/boost_1_38_0.tar.gz fi # tar xzf boost_1_38_0.tar.gz cd boost_1_38_0 GPP_PATH=${OVEROTOP}/tmp/cross/armv7a/arm-angstrom-linux-gnueabi/bin/g++ GPP_VER=`${GPP_PATH} -v 2>&1 | tail -1 | awk '{print $3}'` echo "using gcc : ${GPP_VER} : ${GPP_PATH} ; " > tools/build/v2/user-config.jam sudo apt-get install bjam set +o errexit sudo bjam --toolset=gcc-${GPP_VER} --prefix=/opt/gumros --with-date_time install set -o errexit cd .. else echo "boost appears to be already installed; skipping." fi if [ ! -f /opt/gumros/lib/libboost_date_time-gcc41-mt-1_38.so ] ; then echo "Failed to compile libboost_date_time"; exit; fi I've checked the user-config to make sure everything was kosher as well as making sure the GPP_PATH is correct. However, when I run the scrip I come across compilation errors such as: Reading package lists... Done Building dependency tree Reading state information...

  • All Xen domU LVM volumes corrupt after reboot

    - by zcs
    I'm running a Debian Squeeze dom0, and after rebooting it all 7 of my domUs have data corruption. Each is setup as ext3 partition directly on a separate lvm2 volume. None of the lvm volumes will mount; all have bad superblocks. I've tried e2fsck with each superblock to no avail. What else can I try? Each domU has two LVM volumes connected to it, one for the disk and one for swap. The disk is mounted at root, formatted as a normal ext3 partition as a xen-blk device. The volumes are never mounted outside of the guest OS. I'm running Ubuntu 11.04 using the instructions here. I'm not sure that they didn't shutdown properly, all I know is they were corrupt after I issues a clean 'reboot' on the dom0. Here's a sample Xen config file; the rest are the same except for name, vcpus, memory, vif and disk. name = 'load1' vcpus = 2 memory = 512 vif = ['bridge=prbr0', 'bridge=eth0'] disk = ['phy:/dev/VolGroup00/load1-disk,xvda,w','phy:/dev/VolGroup00/load1-swap,xvdb,w'] #============================================================================ # Debian Installer specific variables def check_bool(name, value): value = str(value).lower() if value in ('t', 'tr', 'tru', 'true'): return True return False global var_check_with_default def var_check_with_default(default, var, val): if val: return val return default xm_vars.var('install', use='Install Debian, default: false', check=check_bool) xm_vars.var("install-method", use='Installation method to use "cdrom" or "network" (default: network)', check=lambda var, val: var_check_with_default('network', var, val)) # install-method == "network" xm_vars.var("install-mirror", use='Debian mirror to install from (default: http://archive.ubuntu.com/ubuntu)', check=lambda var, val: var_check_with_default('http://archive.ubuntu.com/ubuntu', var, val)) xm_vars.var("install-suite", use='Debian suite to install (default: natty)', check=lambda var, val: var_check_with_default('natty', var, val)) # install-method == "cdrom" xm_vars.var("install-media", use='Installation media to use (default: None)', check=lambda var, val: var_check_with_default(None, var, val)) xm_vars.var("install-cdrom-device", use='Installation media to use (default: xvdd)', check=lambda var, val: var_check_with_default('xvdd', var, val)) # Common options xm_vars.var("install-arch", use='Debian mirror to install from (default: amd64)', check=lambda var, val: var_check_with_default('amd64', var, val)) xm_vars.var("install-extra", use='Extra command line options (default: None)', check=lambda var, val: var_check_with_default(None, var, val)) xm_vars.var("install-installer", use='Debian installer to use (default: network uses install-mirror;

  • Odd tcp deadlock under windows

    - by John Robertson
    We are moving large amounts of data on a LAN and it has to happen very rapidly and reliably. Currently we use windows TCP as implemented in C++. Using large (synchronous) sends moves the data much faster than a bunch of smaller (synchronous) sends but will frequently deadlock for large gaps of time (.15 seconds) causing the overall transfer rate to plummet. This deadlock happens in very particular circumstances which makes me believe it should be preventable altogether. More importantly if we don't really know the cause we don't really know it won't happen some time with smaller sends anyway. Can anyone explain this deadlock? Deadlock description (OK, zombie-locked, it isn't dead, but for .15 or so seconds it stops, then starts again) The receiving side sends an ACK. The sending side sends a packet containing the end of a message (push flag is set) The call to socket.recv takes about .15 seconds(!) to return About the time the call returns an ACK is sent by the receiving side The the next packet from the sender is finally sent (why is it waiting? the tcp window is plenty big) The odd thing about (3) is that typically that call doesn't take much time at all and receives exactly the same amount of data. On a 2Ghz machine that's 300 million instructions worth of time. I am assuming the call doesn't (heaven forbid) wait for the received data to be acked before it returns, so the ack must be waiting for the call to return, or both must be delayed by something else. The problem NEVER happens when there is a second packet of data (part of the same message) arriving between 1 and 2. That part very clearly makes it sound like it has to do with the fact that windows TCP will not send back a no-data ACK until either a second packet arrives or a 200ms timer expires. However the delay is less than 200 ms (its more like 150 ms). The third unseemly character (and to my mind the real culprit) is (5). Send is definitely being called well before that .15 seconds is up, but the data NEVER hits the wire before that ack returns. That is the most bizarre part of this deadlock to me. Its not a tcp blockage because the TCP window is plenty big since we set SO_RCVBUF to something like 500*1460 (which is still under a meg). The data is coming in very fast (basically there is a loop spinning out data via send) so the buffer should fill almost immediately. According to msdn the buffer being full and at least one pending send should cause the data to be sent (though in another place it mentions that there various "heuristics" used in deciding when a send hits the wire). Anway, why the sender doesn't actually send more data during that .15 second pause is the most bizarre part to me. The information above was captured on the receiving side via wireshark (except of course the socket.recv return times which were logged in a text file). We tried changing the send buffer to zero and turning off Nagle on the sender (yes, I know Nagle is about not sending small packets - but we tried turning Nagle off in case that was part of the unstated "heuristics" affecting whether the message would be posted to the wire. Technically microsoft's Nagle is that a small packet isn't sent if the buffer is full and there is an outstanding ACK, so it seemed like a possibility).

  • Postfix "warning: cannot get RSA private key from file"

    - by phew
    I just followed this tutorial to set up a postfix mailserver with dovecot and mysql as backend for virtual users. Now I got the most parts working, I can connect to pop3 pop3s imap and imaps. Using echo TEST-MAIL | mail [email protected] works fine, when I log into my hotmail account it shows the email. It also works in reverse hence my MX entry for mydomain.com finally has been propagated, so I am being able to receive emails sent from [email protected] to [email protected] and view them in Thunderbird using STARTTLS via IMAP. Doing a bit more research after I got the error message "5.7.1 : Relay access denied" when trying to send mails to [email protected] using Thunderbird being logged into [email protected], I figured out that my server was acting as an "Open Mail Relay", which - ofcourse - is a bad thing. Digging more into the optional parts of the tutorial like shown workaround.org/comment/2536 and workaround.org/ispmail/squeeze/postfix-smtp-auth I decided to complete these steps aswell to be able to send mails via [email protected] through Mozilla Thunderbird, not getting the error message "5.7.1 : Relay access denied" anymore (as common mailservers reject open relayed emails). But now I ran into an error trying to get postfix working with SMTPS, in /var/log/mail.log it reads Sep 28 17:29:34 domain postfix/smtpd[20251]: warning: cannot get RSA private key from file /etc/ssl/certs/postfix.pem: disabling TLS support Sep 28 17:29:34 domain postfix/smtpd[20251]: warning: TLS library problem: 20251:error:0906D06C:PEM routines:PEM_read_bio:no start line:pem_lib.c:650:Expecting: ANY PRIVATE KEY: Sep 28 17:29:34 domain postfix/smtpd[20251]: warning: TLS library problem: 20251:error:140B0009:SSL routines:SSL_CTX_use_PrivateKey_file:PEM lib:ssl_rsa.c:669: That error is logged right after I try to send a mail from my newly installed mailserver using SMTP SSL/TLS via port 465 in Thunderbird. Thunderbird then tells me a timeout occured. Google has a few results concerning that problem, yet I couldn't get it working with any of those. I would link some of them here but as a new user I am only allowed to use two hyperlinks. My /etc/postfix/master.cf looks like smtp inet n - - - - smtpd smtps inet n - - - - smtpd -o smtpd_tls_wrappermode=yes -o smtpd_sasl_auth_enable=yes and nmap tells me PORT STATE SERVICE [...] 465/tcp open smtps [...] my /etc/postfix/main.cf looks like smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU) biff = no append_dot_mydomain = no readme_directory = no #smtpd_tls_cert_file = /etc/ssl/certs/postfix.pem #default postfix generated #smtpd_tls_key_file = /etc/ssl/private/ssl-cert-snakeoil.key #default postfix generated smtpd_tls_cert_file = /etc/ssl/certs/postfix.pem smptd_tls_key_file = /etc/ssl/private/postfix.pem smtpd_use_tls = yes smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth smptd_sasl_auth_enable = yes smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination myhostname = mydomain.com alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname mydestination = localhost.com, localhost relayhost = mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all virtual_mailbox_domains = mysql:/etc/postfix/mysql-virtual-mailbox-domains.cf virtual_mailbox_maps = mysql:/etc/postfix/mysql-virtual-mailbox-maps.cf virtual_alias_maps = mysql:/etc/postfix/mysql-virtual-alias-maps.cf virtual_transport = dovecot dovecot_destination_recipient_limit = 1 mailbox_command = /usr/lib/dovecot/deliver The *.pem files were created like described in the tutorial above, using Postfix To create a certificate to be used by Postfix use: openssl req -new -x509 -days 3650 -nodes -out /etc/ssl/certs/postfix.pem -keyout /etc/ssl/private/postfix.pem Do not forget to set the permissions on the private key so that no unauthorized people can read it: chmod o= /etc/ssl/private/postfix.pem You will have to tell Postfix where to find your certificate and private key because by default it will look for a dummy certificate file called "ssl-cert-snakeoil": postconf -e smtpd_tls_cert_file=/etc/ssl/certs/postfix.pem postconf -e smtpd_tls_key_file=/etc/ssl/private/postfix.pem I think I don't have to include /etc/dovecot/dovecot.conf here, as login via imaps and pop3s works fine according to the logs. Only problem is making postfix properly use the self-generated, self-signed certificates. Any help appreciated! EDIT: I just tried this different tutorial on generating a self-signed certificate for postfix, still getting the same error. I really don't know what else to test. I also did check for the SSL libraries, but all seems to be fine: root@domain:~# ldd /usr/sbin/postfix linux-vdso.so.1 => (0x00007fff91b25000) libpostfix-global.so.1 => /usr/lib/libpostfix-global.so.1 (0x00007f6f8313d000) libpostfix-util.so.1 => /usr/lib/libpostfix-util.so.1 (0x00007f6f82f07000) libssl.so.0.9.8 => /usr/lib/libssl.so.0.9.8 (0x00007f6f82cb1000) libcrypto.so.0.9.8 => /usr/lib/libcrypto.so.0.9.8 (0x00007f6f82910000) libsasl2.so.2 => /usr/lib/libsasl2.so.2 (0x00007f6f826f7000) libdb-4.8.so => /usr/lib/libdb-4.8.so (0x00007f6f8237c000) libnsl.so.1 => /lib/libnsl.so.1 (0x00007f6f82164000) libresolv.so.2 => /lib/libresolv.so.2 (0x00007f6f81f4e000) libc.so.6 => /lib/libc.so.6 (0x00007f6f81beb000) libdl.so.2 => /lib/libdl.so.2 (0x00007f6f819e7000) libz.so.1 => /usr/lib/libz.so.1 (0x00007f6f817d0000) libpthread.so.0 => /lib/libpthread.so.0 (0x00007f6f815b3000) /lib64/ld-linux-x86-64.so.2 (0x00007f6f83581000) After following Ansgar Wiechers instructions its finally working. postconf -n contained the lines as it should. The certificate/key check via openssl did show that both files are valid. So it indeed has been a permissions problem! Didn't know that chown'ing the /etc/ssl/*/postfix.pem files to postfix:postfix is not enough for postfix to read the files.

  • Active directory authentication for Ubuntu Linux login and cifs mounting home directories...

    - by Jamie
    I've configured my Ubuntu 10.04 Server LTS Beta 2 residing on a windows network to authenticate logins using active directory, then mount a windows share to serve as there home directory. Here is what I did starting from the initial installation of Ubuntu. Download and install Ubuntu Server 10.04 LTS Beta 2 Get updates # sudo apt-get update && sudo apt-get upgrade Install an SSH server (sshd) # sudo apt-get install openssh-server Some would argue that you should "lock sshd down" by disabling root logins. I figure if your smart enough to hack an ssh session for a root password, you're probably not going to be thwarted by the addition of PermitRootLogin no in the /etc/ssh/sshd_config file. If your paranoid or not simply not convinced then edit the file or give the following a spin: # (grep PermitRootLogin /etc/ssh/sshd_conifg && sudo sed -ri 's/PermitRootLogin ).+/\1no/' /etc/ssh/sshd_conifg) || echo "PermitRootLogin not found. Add it manually." Install required packages # sudo apt-get install winbind samba smbfs smbclient ntp krb5-user Do some basic networking housecleaning in preparation for the specific package configurations to come. Determine your windows domain name, DNS server name, and IP address for the active directory server (for samba). For conveniance I set environment variables for the windows domain and DNS server. For me it was (my AD IP address was 192.168.20.11): # WINDOMAIN=mydomain.local && WINDNS=srv1.$WINDOMAIN If you want to figure out what your domain and DNS server is (I was contractor and didn't know the network) check out this helpful reference. The authentication and file sharing processes for the Windows and Linux boxes need to have their clocks agree. Do this with an NTP service, and on the server version of Ubuntu the NTP service comes installed and preconfigured. The network I was joining had the DNS server serving up the NTP service too. # sudo sed -ri "s/^(server[ \t]).+/\1$WINDNS/" /etc/ntp.conf Restart the NTP daemon # sudo /etc/init.d/ntp restart We need to christen the Linux box on the new network, this is done by editing the host file (replace the DNS of with the FQDN of the windows DNS): # sudo sed -ri "s/^(127\.0\.0\.1[ \t]).*/\1$(hostname).$WINDOMAIN localhost $(hostname)/" /etc/hosts Kerberos configuration. The instructions that follow here aren't to be taken literally: the values for MYDOMAIN.LOCAL and srv1.mydomain.local need to be replaced with what's appropriate for your network when you edit the files. Edit the (previously installed above) /etc/krb5.conf file. Find the [libdefaults] section and change (or add) the key value pair (and it is in UPPERCASE WHERE IT NEEDS TO BE): [libdefaults] default_realm = MYDOMAIN.LOCAL Add the following to the [realms] section of the file: MYDOMAIN.LOCAL = { kdc = srv1.mydomain.local admin_server = srv1.mydomain.local default_domain = MYDOMAIN.LOCAL } Add the following to the [domain_realm] section of the file: .mydomain.local = MYDOMAIN.LOCAL mydomain.local = MYDOMAIN.LOCAL Conmfigure samba. When it's all said done, I don't know where SAMBA fits in ... I used cifs to mount the windows shares ... regardless, my system works and this is how I did it. Replace /etc/samba/smb.conf (remember I was working from a clean distro of Ubuntu, so I wasn't worried about breaking anything): [global] security = ads realm = MYDOMAIN.LOCAL password server = 192.168.20.11 workgroup = MYDOMAIN idmap uid = 10000-20000 idmap gid = 10000-20000 winbind enum users = yes winbind enum groups = yes template homedir = /home/%D/%U template shell = /bin/bash client use spnego = yes client ntlmv2 auth = yes encrypt passwords = yes winbind use default domain = yes restrict anonymous = 2 Start and stop various services. # sudo /etc/init.d/winbind stop # sudo service smbd restart # sudo /etc/init.d/winbind start Setup the authentication. Edit the /etc/nsswitch.conf. Here are the contents of mine: passwd: compat winbind group: compat winbind shadow: compat winbind hosts: files dns networks: files protocols: db files services: db files ethers: db files rpc: db files Start and stop various services. # sudo /etc/init.d/winbind stop # sudo service smbd restart # sudo /etc/init.d/winbind start At this point I could login, home directories didn't exist, but I could login. Later I'll come back and add how I got the cifs automounting to work. Numerous resources were considered so I could figure this out. Here is a short list (a number of these links point to mine own questions on the topic): Samba Kerberos Active Directory WinBind Mounting Linux user home directories on CIFS server Authenticating OpenBSD against Active Directory How to use Active Directory to authenticate linux users Mounting windows shares with Active Directory permissions Using Active Directory authentication with Samba on Ubuntu 9.10 server 64bit How practical is to authenticate a Linux server against AD?

  • What is the coolest thing you can do in <10 lines of simple code? Help me inspire beginners!

    - by Tom Ritter
    I'm looking for the coolest thing you can do in a few lines of simple code. I'm sure you can write a Mandelbrot set in Haskell in 15 lines but it's difficult to follow. My goal is to inspire students that programming is cool. We know that programming is cool because you can create anything you imagine - it's the ultimate creative outlet. I want to inspire these beginners and get them over as many early-learning humps as I can. Now, my reasons are selfish. I'm teaching an Intro to Computing course to a group of 60 half-engineering, half business majors; all freshmen. They are the students who came from underprivileged High schools. From my past experience, the group is generally split as follows: a few rock-stars, some who try very hard and kind of get it, the few who try very hard and barely get it, and the few who don't care. I want to reach as many of these groups as effectively as I can. Here's an example of how I'd use a computer program to teach: Here's an example of what I'm looking for: a 1-line VBS script to get your computer to talk to you: CreateObject("sapi.spvoice").Speak InputBox("Enter your text","Talk it") I could use this to demonstrate order of operations. I'd show the code, let them play with it, then explain that There's a lot going on in that line, but the computer can make sense of it, because it knows the rules. Then I'd show them something like this: 4(5*5) / 10 + 9(.25 + .75) And you can see that first I need to do is (5*5). Then I can multiply for 4. And now I've created the Object. Dividing by 10 is the same as calling Speak - I can't Speak before I have an object, and I can't divide before I have 100. Then on the other side I first create an InputBox with some instructions for how to display it. When I hit enter on the input box it evaluates or "returns" whatever I entered. (Hint: 'oooooo' makes a funny sound) So when I say Speak, the right side is what to Speak. And I get that from the InputBox. So when you do several things on a line, like: x = 14 + y; You need to be aware of the order of things. First we add 14 and y. Then we put the result (what it evaluates to, or returns) into x. That's my goal, to have a bunch of these cool examples to demonstrate and teach the class while they have fun. I tried this example on my roommate and while I may not use this as the first lesson, she liked it and learned something. Some cool mathematica programs that make beautiful graphs or shapes that are easy to understand would be good ideas and I'm going to look into those. Here are some complicated actionscript examples but that's a bit too advanced and I can't teach flash. What other ideas do you have?

  • Django ImageField issue with JPEG's

    - by Kieran Lynn
    I am having a major issue with PIL (Python Image Library) in Django and have jumpped through a lot of hoops and have thus far not been able to figure out what the root of the issue is. The problem essentially breaks down to not being able to upload JPEG images through the ImageField in the Django admin. But the issue is not as simple as installing libjpeg. First, I installed PIL (through Buildout) and realized once it was installed that I had not installed libjpeg because JPEG support was not available. Having not setup the server myself, I just assumed that it was not installed and I compiled libjpeg 8 from the source. This ended up in my /usr/local/lib/ directory. I cleared out my Buildout files and rebuilt everything. This time when PIL compiled I had JPEG support. But I went to the Django Admin and tried to upload a JPEG though an ImageField with no luck. I got the "Upload a valid image. The file you uploaded was either not an image or a corrupted image" error. Just as a test I opened up a the Djano shell and ran the following: > import Image > i = Image.open( "/absolute_path/file.jpg" ) > print i <JpegImagePlugin.JpegImageFile image mode=RGB size=940x375 at 0x7F908C529BD8> This runs with no errors and shows that PIL is able to open JPEG's. After doing some reading, I come across this thread: Is it possible to control which libraries apache uses? Looks like PHP also uses libjpeg and is loading before Django, and therefor loading libjpeg 6.2 before. This is show when using lsof: COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME apache2 2561 www-data mem REG 202,1 146032 639276 /usr/lib/libjpeg.so.62.0.0 So my thought is that I should be using libjpeg 6.2. So I removed libjpeg located in my /usr/local/lib directory. After rereading the PIL installation instructions, I realized that I might not have the dev/header files for libjpeg that PIL needs. So I also uninstalled libjpeg using the aptitude uninstaller (sudo aptitude remove libjpeg62). Then to ensure that I got the header files that PIL needed I installed libjpeg using aptitude: (sudo aptget install libjpeg62-dev). From here I cleaned out my Buildout directory, and reran Buildout, which in turn reinstalled PIL. Once again, I have JPEG support, now using the libjpeg62. So I go to test in the Django Admin. Still no JPEG support. So I wanted to test JPEG support in general and see if the exception was not handled, what kind of error it would throw. So in my homepage view I added the following code to open a JPEG image: import Image i = Image.open( "/absolute_path/file.jpg" ) v = i.verify() Then I pass i to the HTML view just to easily see the output. I deploy these changes to the server and restart. I am surprised not to see an error and get the following output: {{ i }} - <JpegImagePlugin.JpegImageFile image mode=RGB size=940x375 at 0x7F908C529BD8> {{ v }} - None So at this point I am really confused: Why can I successfully open a JPEG while the admin cannot? Am I missing something, is this not an issue with libjpeg? If not an issue with libjpeg, why can I upload a PNG with no issues? Any help would be much appreciated, I have been on this for 2 days debugging with no luck. Setup: 1. Rackspace Cloud Server 2. Ubuntu 10.04 3. Django 1.2.3 (Installed though Buildout) 4. PIL 1.1.7 (Installed though Buildout) 5. libjpeg 6.2 (installed through aptitude (sudo aptget install libjpeg62-dev)

  • Problem installing Ubuntu 10.04 64 bit side by side with Vista by using a bootable USB drive. What n

    - by Adam Siddhi
    What happened I decided to install Ubuntu 10.04 64 bit side by side with Vista Home Premium (I guess on another partition) with a USB stick. I found instructions on how to do this here: https://help.ubuntu.com/community/Installation/FromUSBStick To create the bootable USB drive I had to download a program called Unetbootin. That process was simple enough. All I had to do was just choose the disk image option, select the ubuntu-10.04-desktop-amd64.iso image, make sure it recognizes my USB drive and then press OK. It takes only like a few minutes to create a working bootable USB drive. Then I have to restart my computer, enter the BIOS, select my USB drive as the first boot drive, save options and continue with booting up. After this Ubuntu actually loads up. I think this is known as the Live version of Ubuntu so you can try it out before fully installing it. Any ways, on the Ubuntu 10.04 desktop I saw an installer. I click it and begin the installation process. Just so you know, I tried installing it 2 times. I will explain what happened each time: The first time I tried installing Ubuntu 10.04 I got stuck at step 4 of 7. I remember selecting the last option in the window which was Specify Partitions Manually (Advanced) I made my partition for Ubuntu like 52 gigs. I clicked forward and a little pop up window appeared saying Please Wait. So the installation process stalled on this window so I closed out of it and quit the installation process. So at this point I was worried because I had already selected the partition size and assumed it started making it. Since it stalled I had to quit out though. Anyways, once again I reached step 4 of 7 a decided to select the first option which is Install them side by side choosing between them each startup. I figured this was the safe way to go. I did that and the pop up window saying Please Wait popped up again but lasted only like 10 seconds. Then I got to I guess step 6 where it asks you to enter your desired name and password. Did that and clicked forward. The Ubuntu 10.04 installation load screen appeared and the loading bar at the bottom started filling up. So I got to 83% and stalled during the Importing other profile information (I think it was called this. I had the option to do this during I think step 6) process. So at this point I decided to get stop the installation process. I was getting very nervous. I tried to restart the computer but all that happened was that Ubuntu restarted. I finally got the computer to restart. I was pretty sure I had screwed something up big time by this point. As my computer was restarting I entered BIOS again and switched back to it booting from my main hard drive containing Vista. Saved it and continued the boot process. My worst fears were confirmed as Vista would not boot up. I mean I saw the little Microsoft Windows choppy animated green loading bar at the bottom of the screen and then boom! It decided to restart. When it restarted I had the option to run a memory test check to see if there was anything that needed to be repaired. That took like 20 minutes and at the end I saw that I did indeed have to repair something. I had to go through 2 repair processes. After each I had to restart the computer. The 2nd time it went through the repair process it said that it could not fully repair the damage. I was scared and restarted but Vista did load up. I got to my desktop and saw a message saying something like Repairs have been made, Please restart for changes to take effect I noticed that some Notification icons were missing and I could not hear volume in a video. Things were a bit funky. So I did restart and here I am. Now what?! So since I got back into Vista and thankfully have a working Internet connection I am trying to find answers to my problem (that is why I am writing this post). I am scared that I have partioned my hard drive 2 times after researching Installing Ubuntu 10.04 and seeing this post http://techie-buzz.com/foss/ubuntu-10-04-lts-installation-guide.html The author shows screen shots of installing Ubuntu 10.04. He shows the image of step 4 of 7 with a caption at the bottom. I will recreate it below: Select a partitioning option. Unless you want to format all the hard drive and install Ubuntu afresh, select the last option and proceed. Questions If I have indeed partitioned my HD 2 times (which I am sure it is), how do I get to a point where I can see all my bad, unfinished Ubuntu partitions and get rid of them? How do I clean this big mess up? & How can I ensure that this mess will not happen next time I try installing Ubuntu 10.04? Thank you Adam

  • Using JUnit with App Engine and Eclipse

    - by Mark M
    I am having trouble setting up JUnit with App Engine in Eclipse. I have JUnit set up correctly, that is, I can run tests that don't involve the datastore or other services. However, when I try to use the datastore in my tests they fail. The code I am trying right now is from the App Engine site (see below): http://code.google.com/appengine/docs/java/tools/localunittesting.html#Running_Tests So far I have added the external JAR (using Eclipse) appengine-testing.jar. But when I run the tests I get the exception below. So, I am clearly not understanding the instructions to enable the services from the web page mentioned above. Can someone clear up the steps needed to make the App Engine services available in Eclipse? java.lang.NoClassDefFoundError: com/google/appengine/api/datastore/dev/LocalDatastoreService at com.google.appengine.tools.development.testing.LocalDatastoreServiceTestConfig.tearDown(LocalDatastoreServiceTestConfig.java:138) at com.google.appengine.tools.development.testing.LocalServiceTestHelper.tearDown(LocalServiceTestHelper.java:254) at com.cooperconrad.server.MemberTest.tearDown(MemberTest.java:28) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:44) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:41) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:37) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:73) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:46) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:180) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:41) at org.junit.runners.ParentRunner$1.evaluate(ParentRunner.java:173) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:28) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:31) at org.junit.runners.ParentRunner.run(ParentRunner.java:220) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:46) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197) Caused by: java.lang.ClassNotFoundException: com.google.appengine.api.datastore.dev.LocalDatastoreService at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:248) ... 25 more Here is the actual code (pretty much copied from the site): package com.example; import static org.junit.Assert.*; import org.junit.After; import org.junit.Before; import org.junit.Test; import com.google.appengine.api.datastore.DatastoreService; import com.google.appengine.api.datastore.DatastoreServiceFactory; import com.google.appengine.api.datastore.Entity; import com.google.appengine.api.datastore.Query; import com.google.appengine.tools.development.testing.LocalDatastoreServiceTestConfig; import com.google.appengine.tools.development.testing.LocalServiceTestHelper; public class MemberTest { private final LocalServiceTestHelper helper = new LocalServiceTestHelper(new LocalDatastoreServiceTestConfig()); @Before public void setUp() { helper.setUp(); } @After public void tearDown() { helper.tearDown(); } // run this test twice to prove we're not leaking any state across tests private void doTest() { DatastoreService ds = DatastoreServiceFactory.getDatastoreService(); assertEquals(0, ds.prepare(new Query("yam")).countEntities()); ds.put(new Entity("yam")); ds.put(new Entity("yam")); assertEquals(2, ds.prepare(new Query("yam")).countEntities()); } @Test public void testInsert1() { doTest(); } @Test public void testInsert2() { doTest(); } @Test public void foo() { assertEquals(4, 2 + 2); } }

  • EXSLT date:format-date template without document() XSLT 1.0

    - by DashaLuna
    Hello guys, I'm using date:format-date template EXSLT file I'm using XSLT 1.0 and MSXML3.0 as the processor. My date:format-date template EXSLT file's declaration is: <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" xmlns:tui="http://www.travelbound.co.uk/" xmlns:date="http://exslt.org/dates-and-times" exclude-result-prefixes="msxsl tui date" version="1.0"> ... </xsl:stylesheet> I cannot use document() function due to the 3rd party restrictions. So I have changed the months and days (similarly) from XML snippet: <date:months> <date:month length="31" abbr="Jan">January</date:month> <date:month length="28" abbr="Feb">February</date:month> <date:month length="31" abbr="Mar">March</date:month> <date:month length="30" abbr="Apr">April</date:month> <date:month length="31" abbr="May">May</date:month> <date:month length="30" abbr="Jun">June</date:month> <date:month length="31" abbr="Jul">July</date:month> <date:month length="31" abbr="Aug">August</date:month> <date:month length="30" abbr="Sep">September</date:month> <date:month length="31" abbr="Oct">October</date:month> <date:month length="30" abbr="Nov">November</date:month> <date:month length="31" abbr="Dec">December</date:month> </date:months> to the variable: <xsl:variable name="months"> <month length="31" abbr="Jan">January</month> <month length="28" abbr="Feb">February</month> <month length="31" abbr="Mar">March</month> <month length="30" abbr="Apr">April</month> <month length="31" abbr="May">May</month> <month length="30" abbr="Jun">June</month> <month length="31" abbr="Jul">July</month> <month length="31" abbr="Aug">August</month> <month length="30" abbr="Sep">September</month> <month length="31" abbr="Oct">October</month> <month length="30" abbr="Nov">November</month> <month length="31" abbr="Dec">December</month> </xsl:variable> And correspondingly, I've changed the code that originally uses document() function from: [from month processing bit of EXSLT stylesheet] <xsl:variable name="month-node" select="document('')/*/date:months/date:month[number($month)]" /> to use MSXML3.0 node-set function: <xsl:variable name="month-node" select="msxsl:node-set($months)/month[number($month)]" /> So I assumed that this would work. According to the EXLT instructions "The format pattern string is interpreted as described for the JDK 1.1 SimpleDateFormat class." [I used current version]. I'm specifing the month in accordance to SimpleDateFormat class as 'dd MMMMM yyyy' so that the month will be the full month's name, for example January. But it doesn't work :( I've looked in EXSLT stylesheet and it has got the logic to do that. Also there is logic to display the name of the week for a day using 'E' pattern, which doesn't work for me. Maybe changing from using document() to variables broke it. Would really appreciate any help. Many thanks!

  • The best cross platform (portable) arbitrary precision math library

    - by Siu Ching Pong - Asuka Kenji
    Dear ninjas / hackers / wizards, I'm looking for a good arbitrary precision math library in C or C++. Could you please give me some advices / suggestions? The primary requirements: It MUST handle arbitrarily big integers (my primary interest is on integers). In case that you don't know what the word arbitrarily big means, imagine something like 100000! (the factorial of 100000). The precision MUST NOT NEED to be specified during library initialization / object creation. The precision should ONLY be constrained by the available resources of the system. It SHOULD utilize the full power of the platform, and should handle "small" numbers natively. That means on a 64-bit platform, calculating 2^33 + 2^32 should use the available 64-bit CPU instructions. The library SHOULD NOT calculate this in the same way as it does with 2^66 + 2^65 on the same platform. It MUST handle addition (+), subtraction (-), multiplication (*), integer division (/), remainder (%), power (**), increment (++), decrement (--), gcd(), factorial(), and other common integer arithmetic calculations efficiently. Ability to handle functions like sqrt() (square root), log() (logarithm) that do not produce integer results is a plus. Ability to handle symbolic computations is even better. Here are what I found so far: Java's BigInteger and BigDecimal class: I have been using these so far. I have read the source code, but I don't understand the math underneath. It may be based on theories / algorithms that I have never learnt. The built-in integer type or in core libraries of bc / Python / Ruby / Haskell / Lisp / Erlang / OCaml / PHP / some other languages: I have ever used some of these, but I have no idea on which library they are using, or which kind of implementation they are using. What I have already known: Using a char as a decimal digit, and a char* as a decimal string and do calculations on the digits using a for-loop. Using an int (or a long int, or a long long) as a basic "unit" and an array of it as an arbitrary long integer, and do calculations on the elements using a for-loop. Booth's multiplication algorithm What I don't know: Printing the binary array mentioned above in decimal without using naive methods. Example of a naive method: (1) add the bits from the lowest to the highest: 1, 2, 4, 8, 16, 32, ... (2) use a char* string mentioned above to store the intermediate decimal results). What I appreciate: Good comparisons on GMP, MPFR, decNumber (or other libraries that are good in your opinion). Good suggestions on books / articles that I should read. For example, an illustration with figures on how a un-naive arbitrarily long binary to decimal conversion algorithm works is good. Any help. Please DO NOT answer this question if: you think using a double (or a long double, or a long long double) can solve this problem easily. If you do think so, it means that you don't understand the issue under discussion. you have no experience on arbitrary precision mathematics. Thank you in advance! Asuka Kenji

  • Chaining CSS classes in IE6 - Trying to find a jQuery solution?

    - by Mike Baxter
    Right, perhaps I ask the impossible? I consider myself fairly new to Javscript and jQuery, but that being said, I have written some fairly complex code recently so I am definitely getting there... however I am now possed with a rather interesting issue at my current freelance contract. The previous web coder has taken a Grid-960 approach to the HTML and as a result has used chained classes to style many of the elements. The example below is typical of what can be found in the code: <div class='blocks four-col-1 orange highlight'>Some content</div> And in the css there will be different declarations for: (not actual css... but close enough) .blocks {margin-right:10px;} .orange {background-image:url(someimage.jpg);} .highlight {font-weight:bold;} .four-col-1 {width:300px;} and to make matters worse... this is in the CSS: .blocks.orange.highlight {background-colour:#dd00ff;} Anyone not familiar with this particular bug can read more on it here: http://www.ryanbrill.com/archives/multiple-classes-in-ie/ it is very real and very annoying. Without wanting to go into the merrits of not chaining classes (I told them this, but it is no longer feasible to change their approach... 100 hand coded pages into a 150 page website, no CMS... sigh) and without the luxury of being able to change the way these blocks are styled... can anyone advise me on the complexity and benefits between any of my below proposed approaches or possible other options that would adequately solve this problem. Potential Solution 1 Using conditional comments I am considering loading a jquery script only for IE6 that: Reads the class of all divs in a certain section of the page and pushes to an array creates empty boxes off screen with only one of the classes applied at a time Reads the applied CSS values for each box Re-applies these styles to the individual box, somehow bearing in mind the order in which they are called and overwriting conflicting instructions as required Potential Solution 2 read the class of all divs in a certain section of the page and push to an array Scan the document for links to style sheets Ajax grab the stylesheets and traverse looking for matching names to those in class array Apply styles as needed Potential Solution 3 Create an IE6 only stylesheet containing the exact style to be applied as a unique name (ie: class='blocks orange highlight' becomes class='blocks-orange-highlight') Traverse the document in IE6 and convert all spaces in class declarations to hyphens and reapply classes based on new style name Summary: Solution 1 allows the people at this company to apply any styles in the future and the script will adjust as needed. However it does not allow for the chained style to be added, only the individual style... it is also processor intensive and time consuming, but also the most likely to be converted into a plugin that could be used the world over Solution 2 is a potential nightmare to code. But again will allow for an endless number of updates without breaking Solution 3 will require someone at the companty to hardcode the new styles every time they make a change, and if they don't, IE6 will break. Ironically the site, whilst needing to conform to IE6 in a limited manner, does not need to run wihtout javascript (they've made the call... have JS or go away), so consider all jQuery and JS solutions to be 'game on'. Did I mention how much i hate IE6? Anyway... any thoughts or comments would be appreciated. I will continue to develop my own solution and if I discover one that can be turned into a jQuery plugin I will post it here in the comments. Regards, Mike.

  • Thread Synchronisation 101

    - by taspeotis
    Previously I've written some very simple multithreaded code, and I've always been aware that at any time there could be a context switch right in the middle of what I'm doing, so I've always guarded access the shared variables through a CCriticalSection class that enters the critical section on construction and leaves it on destruction. I know this is fairly aggressive and I enter and leave critical sections quite frequently and sometimes egregiously (e.g. at the start of a function when I could put the CCriticalSection inside a tighter code block) but my code doesn't crash and it runs fast enough. At work my multithreaded code needs to be a tighter, only locking/synchronising at the lowest level needed. At work I was trying to debug some multithreaded code, and I came across this: EnterCriticalSection(&m_Crit4); m_bSomeVariable = true; LeaveCriticalSection(&m_Crit4); Now, m_bSomeVariable is a Win32 BOOL (not volatile), which as far as I know is defined to be an int, and on x86 reading and writing these values is a single instruction, and since context switches occur on an instruction boundary then there's no need for synchronising this operation with a critical section. I did some more research online to see whether this operation did not need synchronisation, and I came up with two scenarios it did: The CPU implements out of order execution or the second thread is running on a different core and the updated value is not written into RAM for the other core to see; and The int is not 4-byte aligned. I believe number 1 can be solved using the "volatile" keyword. In VS2005 and later the C++ compiler surrounds access to this variable using memory barriers, ensuring that the variable is always completely written/read to the main system memory before using it. Number 2 I cannot verify, I don't know why the byte alignment would make a difference. I don't know the x86 instruction set, but does mov need to be given a 4-byte aligned address? If not do you need to use a combination of instructions? That would introduce the problem. So... QUESTION 1: Does using the "volatile" keyword (implicity using memory barriers and hinting to the compiler not to optimise this code) absolve a programmer from the need to synchronise a 4-byte/8-byte on x86/x64 variable between read/write operations? QUESTION 2: Is there the explicit requirement that the variable be 4-byte/8-byte aligned? I did some more digging into our code and the variables defined in the class: class CExample { private: CRITICAL_SECTION m_Crit1; // Protects variable a CRITICAL_SECTION m_Crit2; // Protects variable b CRITICAL_SECTION m_Crit3; // Protects variable c CRITICAL_SECTION m_Crit4; // Protects variable d // ... }; Now, to me this seems excessive. I thought critical sections synchronised threads between a process, so if you've got one you can enter it and no other thread in that process can execute. There is no need for a critical section for each variable you want to protect, if you're in a critical section then nothing else can interrupt you. I think the only thing that can change the variables from outside a critical section is if the process shares a memory page with another process (can you do that?) and the other process starts to change the values. Mutexes would also help here, named mutexes are shared across processes, or only processes of the same name? QUESTION 3: Is my analysis of critical sections correct, and should this code be rewritten to use mutexes? I have had a look at other synchronisation objects (semaphores and spinlocks), are they better suited here? QUESTION 4: Where are critical sections/mutexes/semaphores/spinlocks best suited? That is, which synchronisation problem should they be applied to. Is there a vast performance penalty for choosing one over the other? And while we're on it, I read that spinlocks should not be used in a single-core multithreaded environment, only a multi-core multithreaded environment. So, QUESTION 5: Is this wrong, or if not, why is it right? Thanks in advance for any responses :)

  • Is it possible to implement bitwise operators using integer arithmetic?

    - by Statement
    Hello World! I am facing a rather peculiar problem. I am working on a compiler for an architecture that doesn't support bitwise operations. However, it handles signed 16 bit integer arithmetics and I was wondering if it would be possible to implement bitwise operations using only: Addition (c = a + b) Subtraction (c = a - b) Division (c = a / b) Multiplication (c = a * b) Modulus (c = a % b) Minimum (c = min(a, b)) Maximum (c = max(a, b)) Comparisons (c = (a < b), c = (a == b), c = (a <= b), et.c.) Jumps (goto, for, et.c.) The bitwise operations I want to be able to support are: Or (c = a | b) And (c = a & b) Xor (c = a ^ b) Left Shift (c = a << b) Right Shift (c = a b) (All integers are signed so this is a problem) Signed Shift (c = a b) One's Complement (a = ~b) (Already found a solution, see below) Normally the problem is the other way around; how to achieve arithmetic optimizations using bitwise hacks. However not in this case. Writable memory is very scarce on this architecture, hence the need for bitwise operations. The bitwise functions themselves should not use a lot of temporary variables. However, constant read-only data & instruction memory is abundant. A side note here also is that jumps and branches are not expensive and all data is readily cached. Jumps cost half the cycles as arithmetic (including load/store) instructions do. On other words, all of the above supported functions cost twice the cycles of a single jump. Some thoughts that might help: I figured out that you can do one's complement (negate bits) with the following code: // Bitwise one's complement b = ~a; // Arithmetic one's complement b = -1 - a; I also remember the old shift hack when dividing with a power of two so the bitwise shift can be expressed as: // Bitwise left shift b = a << 4; // Arithmetic left shift b = a * 16; // 2^4 = 16 // Signed right shift b = a >>> 4; // Arithmetic right shift b = a / 16; For the rest of the bitwise operations I am slightly clueless. I wish the architects of this architecture would have supplied bit-operations. I would also like to know if there is a fast/easy way of computing the power of two (for shift operations) without using a memory data table. A naive solution would be to jump into a field of multiplications: b = 1; switch (a) { case 15: b = b * 2; case 14: b = b * 2; // ... exploting fallthrough (instruction memory is magnitudes larger) case 2: b = b * 2; case 1: b = b * 2; } Or a Set & Jump approach: switch (a) { case 15: b = 32768; break; case 14: b = 16384; break; // ... exploiting the fact that a jump is faster than one additional mul // at the cost of doubling the instruction memory footprint. case 2: b = 4; break; case 1: b = 2; break; }

  • How to show form in front in C#

    - by corlettk
    Folks, Please does anyone know how to show a Form from an otherwise invisible application, and have it get the focus (i.e. appear on top of other windows)? I'm working in C# .NET 3.5. I suspect I've taken "completely the wrong approach"... I do not Application.Run(new TheForm ()) instead I (new TheForm()).ShowModal()... The Form is basically a modal dialogue, with a few check-boxes; a text-box, and OK and Cancel Buttons. The user ticks a checkbox and types in a description (or whatever) then presses OK, the form disappears and the process reads the user-input from the Form, Disposes it, and continues processing. This works, except when the form is show it doesn't get the focus, instead it appears behind the "host" application, until you click on it in the taskbar (or whatever). This is a most annoying behaviour, which I predict will cause many "support calls", and the existing VB6 version doesn't have this problem, so I'm going backwards in usability... and users won't accept that (and nor should they). So... I'm starting to think I need to rethink the whole shebang... I should show the form up front, as a "normal application" and attach the remainer of the processing to the OK-button-click event. It should work, But that will take time which I don't have (I'm already over time/budget)... so first I really need to try to make the current approach work... even by quick-and-dirty methods. So please does anyone know how to "force" a .NET 3.5 Form (by fair means or fowl) to get the focus? I'm thinking "magic" windows API calls (I know Twilight Zone: This only appears to be an issue at work, we're I'm using Visual Studio 2008 on Windows XP SP3... I've just failed to reproduce the problem with an SSCCE (see below) at home on Visual C# 2008 on Vista Ulimate... This works fine. Huh? WTF? Also, I'd swear that at work yesterday showed the form when I ran the EXE, but not when F5'ed (or Ctrl-F5'ed) straight from the IDE (which I just put up with)... At home the form shows fine either way. Totaly confusterpating! It may or may not be relevant, but Visual Studio crashed-and-burned this morning when the project was running in debug mode and editing the code "on the fly"... it got stuck what I presumed was an endless loop of error messages. The error message was something about "can't debug this project because it is not the current project, or something... So I just killed it off with process explorer. It started up again fine, and even offered to recover the "lost" file, an offer which I accepted. using System; using System.Windows.Forms; namespace ShowFormOnTop { static class Program { [STAThread] static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); //Application.Run(new Form1()); Form1 frm = new Form1(); frm.ShowDialog(); } } } Background: I'm porting an existing VB6 implementation to .NET... It's a "plugin" for a "client" GIS application called MapInfo. The existing client "worked invisibly" and my instructions are "to keep the new version as close as possible to the old version", which works well enough (after years of patching); it's just written in an unsupported language, so we need to port it. About me: I'm pretty much a noob to C# and .NET generally, though I've got a bottoms wiping certificate, I have been a professional programmer for 10 years; So I sort of "know some stuff". Any insights would be most welcome... and Thank you all for taking the time to read this far. Consiseness isn't (apparently) my forte. Cheers. Keith.

  • How can I get my Web API app to run again after upgrading to MVC 5 and Web API 2?

    - by Clay Shannon
    I upgraded my Web API app to the funkelnagelneu versions using this guidance: http://www.asp.net/mvc/tutorials/mvc-5/how-to-upgrade-an-aspnet-mvc-4-and-web-api-project-to-aspnet-mvc-5-and-web-api-2 However, after going through the steps (it seems all this should be automated, anyway), I tried to run it and got, "A project with an Output Type of Class Library cannot be started directly" What in Sam Hills Brothers Coffee is going on here? Who said this was a class library? So I opened Project Properties, and changed it (it was marked as "Class Library" for some reason - it either wasn't yesterday, or was and worked fine) to an Output Type of "Windows Application" ("Console Application" and "Class Library" being the only other options). Now it won't compile, complaining: "*Program 'c:\Platypus_Server_WebAPI\PlatypusServerWebAPI\PlatypusServerWebAPI\obj\Debug\PlatypusServerWebAPI.exe' does not contain a static 'Main' method suitable for an entry point...*" How can I get my Web API app back up and running in view of this quandary? UPDATE Looking in packages.config, two entries seem chin-scratch-worthy: <package id="Microsoft.AspNet.Providers" version="1.2" targetFramework="net40" /> <package id="Microsoft.Web.Infrastructure" version="1.0.0.0" targetFramework="net40" /> All the others target net451. Could this be the problem? Should I remove these packages? UPDATE 2 I tried to uninstall the Microsoft.Web.Infrastructure package (its description leads me to believe I don't need it; also, it has no dependencies) via the NuGet package manager, but it tells me, "NuGet failed to install or uninstall the selected package in the following project(s). [mine]" UPDATE 3 I went through the steps in again, and found that I had missed one step. I had to change this entry in the Application web.config File : <dependentAssembly> <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" /> <bindingRedirect oldVersion="1.0.0.0-5.0.0.0" newVersion="5.0.0.0" /> </dependentAssembly> (from "4.0.0.0" to "5.0.0.0") ...but I still get the same result - it rebuilds/compiles, but won't run, with "A project with an Output Type of Class Library cannot be started directly" UPDATE 4 Thinking about the err msg, that it can't directly open a class library, I thought, "Sure you can't/won't -- this is a web app, not a project. So I followed a hunch, closed the project, and reopened it as a website (instead of reopening a project). That has gotten me further, at least; now I see a YSOD: Could not load file or assembly 'System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified. UPDATE 5 Note: The project is now (after being opened as a web site) named "localhost_48614" And...there is no longer a "References" folder...?!?!? As to that YSOD I'm getting, the official instructions (http://www.asp.net/mvc/tutorials/mvc-5/how-to-upgrade-an-aspnet-mvc-4-and-web-api-project-to-aspnet-mvc-5-and-web-api-2) said to do this, and I quote: "Update all elements that contain “System.Web.WebPages.Razor” from version “2.0.0.0” to version“3.0.0.0”." UPDATE 6 When I select Tools Library Package Manager Manage NuGet Packages for Solution now, I get, "Operation failed. Unable to locate the solution directory. Please ensure that the solution has been saved." So I save it, and it saves it with this funky new name (C:\Users\clay\Documents\Visual Studio 2013\Projects\localhost_48614\localhost_48614.sln) I get the Yellow Strip of Enlightenment across the top of the NuGet Package Manager telling me, "Some NuGet packages are missing from this solution. Click to restore from your online package sources." I do (click the "Restore" button, that is), and it downloads the missing packages ... I end up with the 30 packages. I try to run the app/site again, and ... the erstwhile YSOD becomes a compilation error: The pre-application start initialization method Start on type System.Web.Mvc.PreApplicationStartCode threw an exception with the following error message: Could not load file or assembly 'System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.. Argghhhh!!! (and it's not even talk-like-a-pirate day).

  • How to install MariaDB rpms in CentOS 6.4 using rpm (not yum cmd) + handling mysql-libs conflicts

    - by Pat C
    I need to script the install of MariaDB using the rpm command in CentOS 6.4. I can't use yum since it's going to be an offline install so there's no access to the repository. The only MySQL package installed is mysql-libs as various other packages in CentOS depend on it. When I did a test install of MariaDB with yum it correctly accounted for mysql-libs and uninstalled it at the end as MariaDB could handle the dependencies after it was installed: [root@new-host-6 ~]# yum install MariaDB-client MariaDB-common MariaDB-compat MariaDB-devel MariaDB-server MariaDB-shared Loaded plugins: downloadonly, fastestmirror, refresh-packagekit, security, verify Loading mirror speeds from cached hostfile * base: mirrors.kernel.org * extras: mirror.keystealth.org * updates: mirror.umd.edu Setting up Install Process Resolving Dependencies --> Running transaction check ---> Package MariaDB-client.x86_64 0:5.5.32-1 will be installed ---> Package MariaDB-common.x86_64 0:5.5.32-1 will be installed ---> Package MariaDB-compat.x86_64 0:5.5.32-1 will be obsoleting ---> Package MariaDB-devel.x86_64 0:5.5.32-1 will be installed ---> Package MariaDB-server.x86_64 0:5.5.32-1 will be installed ---> Package MariaDB-shared.x86_64 0:5.5.32-1 will be obsoleting ---> Package mysql-libs.x86_64 0:5.1.66-2.el6_3 will be obsoleted --> Finished Dependency Resolution Dependencies Resolved ==================================================================================================================================================================== Package Arch Version Repository Size ==================================================================================================================================================================== Installing: MariaDB-client x86_64 5.5.32-1 mariadb 10 M MariaDB-common x86_64 5.5.32-1 mariadb 23 k MariaDB-compat x86_64 5.5.32-1 mariadb 2.7 M replacing mysql-libs.x86_64 5.1.66-2.el6_3 MariaDB-devel x86_64 5.5.32-1 mariadb 5.6 M MariaDB-server x86_64 5.5.32-1 mariadb 34 M MariaDB-shared x86_64 5.5.32-1 mariadb 1.1 M replacing mysql-libs.x86_64 5.1.66-2.el6_3 Transaction Summary ==================================================================================================================================================================== Install 6 Package(s) Total download size: 53 M Is this ok [y/N]: y Downloading Packages: (1/6): MariaDB-5.5.32-centos6-x86_64-client.rpm | 10 MB 00:06 (2/6): MariaDB-5.5.32-centos6-x86_64-common.rpm | 23 kB 00:00 (3/6): MariaDB-5.5.32-centos6-x86_64-compat.rpm | 2.7 MB 00:02 (4/6): MariaDB-5.5.32-centos6-x86_64-devel.rpm | 5.6 MB 00:06 (5/6): MariaDB-5.5.32-centos6-x86_64-server.rpm | 34 MB 00:23 (6/6): MariaDB-5.5.32-centos6-x86_64-shared.rpm | 1.1 MB 00:00 -------------------------------------------------------------------------------------------------------------------------------------------------------------------- Total 1.3 MB/s | 53 MB 00:40 warning: rpmts_HdrFromFdno: Header V4 DSA/SHA1 Signature, key ID 1bb943db: NOKEY Retrieving key from https://yum.mariadb.org/RPM-GPG-KEY-MariaDB Importing GPG key 0x1BB943DB: Userid: "Daniel Bartholomew (Monty Program signing key) <[email protected]>" From : https://yum.mariadb.org/RPM-GPG-KEY-MariaDB Is this ok [y/N]: y Running rpm_check_debug Running Transaction Test Transaction Test Succeeded Running Transaction Warning: RPMDB altered outside of yum.

My question is, what is the equivalent way to install the MariaDB packages using the rpm command only as opposed to yum? If I do rpm -ivh MariaDB*.rpm, I will get a ton of messages like the following about conflicts with mysql-libs: file /etc/my.cnf from install of MariaDB-common-5.5.32-1.x86_64 conflicts with file from package mysql-libs-5.1.66-2.el6_3.x86_64 file /usr/share/mysql/charsets/Index.xml from install of MariaDB-common-5.5.32-1.x86_64 conflicts with file from package mysql-libs-5.1.66-2.el6_3.x86_64 I then used the --force option to install the MariaDB rpms and uninstalled mysql-lib, I didn't get any weird messages but I'm not sure that is the cleanest method to handle the conflicts and do the install. So can someone confirm that installing MariaDB with the following rpm commands would be the same as using yum to install the packages and handle mysql-libs conflicts/removal: rpm -ivh --force MariaDB*.rpm rpm -e mysql-libs Thanks for any input!
