  • Subterranean IL: Exception handler semantics

    - by Simon Cooper
    In my blog posts on fault and filter exception handlers, I said that the same behaviour could be replicated using normal catch blocks. Well, that isn't entirely true... Changing the handler semantics Consider the following: .try { .try { .try { newobj instance void [mscorlib]System.Exception::.ctor() // IL for: // e.Data.Add("DictKey", true) throw } fault { ldstr "1: Fault handler" call void [mscorlib]System.Console::WriteLine(string) endfault } } filter { ldstr "2a: Filter logic" call void [mscorlib]System.Console::WriteLine(string) // IL for: // (bool)((Exception)e).Data["DictKey"] endfilter }{ ldstr "2b: Filter handler" call void [mscorlib]System.Console::WriteLine(string) leave.s Return } } catch object { ldstr "3: Catch handler" call void [mscorlib]System.Console::WriteLine(string) leave.s Return } Return: // rest of method If the filter handler is engaged (true is inserted into the exception dictionary) then the filter handler gets engaged, and the following gets printed to the console: 2a: Filter logic 1: Fault handler 2b: Filter handler and if the filter handler isn't engaged, then the following is printed: 2a:Filter logic 1: Fault handler 3: Catch handler Filter handler execution The filter handler is executed first. Hmm, ok. Well, what happens if we replaced the fault block with the C# equivalent (with the exception dictionary value set to false)? .try { // throw exception } catch object { ldstr "1: Fault handler" call void [mscorlib]System.Console::WriteLine(string) rethrow } we get this: 1: Fault handler 2a: Filter logic 3: Catch handler The fault handler is executed first, instead of the filter block. Eh? This change in behaviour is due to the way the CLR searches for exception handlers. When an exception is thrown, the CLR stops execution of the thread, and searches up the stack for an exception handler that can handle the exception and stop it propagating further - catch or filter handlers. It checks the type clause of catch clauses, and executes the code in filter blocks to see if the filter can handle the exception. When the CLR finds a valid handler, it saves the handler's location, then goes back to where the exception was thrown and executes fault and finally blocks between there and the handler location, discarding stack frames in the process, until it reaches the handler. So? By replacing a fault with a catch, we have changed the semantics of when the filter code is executed; by using a rethrow instruction, we've split up the exception handler search into two - one search to find the first catch, then a second when the rethrow instruction is encountered. This is only really obvious when mixing C# exception handlers with fault or filter handlers, so this doesn't affect code written only in C#. However it could cause some subtle and hard-to-debug effects with object initialization and ordering when using and calling code written in a language that can compile fault and filter handlers.

  • juju spends bootstrap-timeout with a final message it cannot find /var/lib/juju/nonce.txt

    - by user285199
    I build two VMware's machines. First one with MAAS, second one with a fresh installation from MAAS. Region controller was installed with Ubuntu 12.04 distribution, and upgraded (. Node computing was installed from MAAS with Quantal 12.10. Juju was installed and upgraded to 1.18 (from ppa:juju/stable repository). MAAS was upgraded from cloud-archive:tools repository. In debug mode, I got how Juju connects to node. Then I run the same instruction: ssh -o "StrictHostKeyChecking no" -o "PasswordAuthentication no" -i /home/lliurex/.juju/ssh/juju_id_rsa -i /home/lliurex/.ssh/id_rsa [email protected] /bin/bash It worked (with and without /bin/bash). When Juju spends all bootstrap-timeout tells it has not found /var/lib/juju/nonce.txt file. It's true, it doesn't exist. It doesn't mind if you put a timeout of 1800, 3600 or 72000, it always finishes the same.

  • Firefox messages in /var/log/messages

    - by Roy
    I happened to be browsing through /var/log/messages for another reason, and I stumbled across some messages apparently related to Firefox like this: Apr 5 15:36:59 myserver kernel: [18091.188462] type=1503 audit(1333658219.144:19): operation="open" pid=6396 parent=1 profile="/usr/lib/firefox-11.0/firefox{,*[^s][^h]}" requested_mask="::r" denied_mask="::r" fsuid=1000 ouid=0 name="/shr/RiverTrip.gpx" which are really puzzling me because I really don't see why Firefox would know about these files let alone output messages about them. The /shr directory is an NTFS partition I set up on my laptop so I can access it with either Ubuntu or Windows XP. The messages are consistently showing up for a few of the files in that directory, but not all. I haven't even looked at those files or done anything else with them in a long time! I have no idea what's special with those files; they appear to be picked at random as far as I can tell. I am using Ubuntu Release 10.04 (lucid), Kernel Linux 2.6.32-38, GNOME 2.30.2, Firefox 11.0 . I hope someone can explain these spooky messages!

  • Unable to install any packages due to unrecoverable fatal error /var/lib/dpkg/diversions

    - by gforces
    I am currently unable to install any packages. I receive the following error: dpkg: unrecoverable fatal error, aborting: too-long line or missing newline in `/var/lib/dpkg/diversions I have tried various approaches: sudo dpkg --configure -a sudo apt-get clean sudo dpkg-divert --list sudo apt-get check sudo apt-get install -f etc. but all to no avail. Either the output was apparently normal or the error above was thrown. I'm stumped as to how to proceed and would appreciate any assistance. If any further info is required just ask. Thanks for the reply. I followed the suggestions and am now getting a different error: (Reading database ... 50%dpkg: unrecoverable fatal error, aborting: files list file for package 'libksane0' is missing final newline E: Sub-process /usr/bin/dpkg returned an error code (2) Here is the link for the current diversions: http://paste.ubuntu.com/823500/ and the old broken one: http://paste.ubuntu.com/823502/ I tried to reinstall libksane0 but the same error occurred.

  • Wordpress asks for FTP credentials, even though owner of the whole /var/www is www-data

    - by dmt0
    I'm trying to get Wordpress to run on my local Ubuntu 12.10 installation. When I try to install themes/plugins, it asks me for FTP credentials. I've been trying to get this to work for 2 days now. Everywhere on the web it says you should change the owner:group of your Wordpress directory to whateverowner:group runs your apache server - in my case www-data:www-data. I've done this, and even tryed setting permissions to the whole /var/www directory to 777, restarting apache and the whole system. But wordpress is still asking me for the FTP credentials. What else could this be?

  • '/'var/www/' vs '/home/$USER/public_html'

    - by OrganizedFellow
    I recently started using Ubuntu as a LAMP server. I've come across plenty of tutorials that say to place the files at '/var/www/' and I've also seen others that put them in '/home/$USER/public_html/'. During my testing and figuring stuff out, I was successfully able to view a test site URL from each location. Is one better than the other? I thought that maybe it was just preference. But the more I think about it, the more I want to keep all my work in my Home folder.

  • How to recreate Windows Live Mail filter rules in Thunderbird?

    - by FernandoSBS
    I have some filters in Windows Live Mail that I'm trying to port to thunderbird without success. It seems Thunderbird filter is very limited. Here is an ex of a filter i'm trying to recreate: Apply this rule after the message arrives Where the From line contains '[email protected]' or '[email protected]' or 'Programa TAM Fidelidade' and Where the message body contains 'esteja visualizando' and 'por ser cadastrado no Programa TAM Fidelidade' Move it to the Deleted items folder and Stop processing more rules In Thunderbird I can´t combine a list of "or"s with some "and"s, because it only allows you to select "message matches ALL of the criteria below" or "ANY of the below". Am I missing something or it really is very limited?

  • chrooted sftp user with write permissions to /var/www

    - by matthew
    I am getting confused about this setup that I am trying to deploy. I hope someone of you folks can lend me a hand: much much appreciated. Background info Server is Debian 6.0, ext3, with Apache2/SSL and Nginx at the front as reverse proxy. I need to provide sftp access to the Apache root directory (/var/www), making sure that the sftp user is chrooted to that path with RWX permissions. All this without modifying any default permission in /var/www. drwxr-xr-x 9 root root 4096 Nov 4 22:46 www Inside /var/www -rw-r----- 1 www-data www-data 177 Mar 11 2012 file1 drwxr-x--- 6 www-data www-data 4096 Sep 10 2012 dir1 drwxr-xr-x 7 www-data www-data 4096 Sep 28 2012 dir2 -rw------- 1 root root 19 Apr 6 2012 file2 -rw------- 1 root root 3548528 Sep 28 2012 file3 drwxr-x--- 6 www-data www-data 4096 Aug 22 00:11 dir3 drwxr-x--- 5 www-data www-data 4096 Jul 15 2012 dir4 drwxr-x--- 2 www-data www-data 536576 Nov 24 2012 dir5 drwxr-x--- 2 www-data www-data 4096 Nov 5 00:00 dir6 drwxr-x--- 2 www-data www-data 4096 Nov 4 13:24 dir7 What I have tried created a new group secureftp created a new sftp user, joined to secureftp and www-data groups also with nologin shell. Homedir is / edited sshd_config with Subsystem sftp internal-sftp AllowTcpForwarding no Match Group <secureftp> ChrootDirectory /var/www ForceCommand internal-sftp I can login with the sftp user, list files but no write action is allowed. Sftp user is in the www-data group but permissions in /var/www are read/read+x for the group bit so... It doesn't work. I've also tried with ACL, but as I apply ACL RWX permissions for the sftp user to /var/www (dirs and files recursively), it will change the unix permissions as well which is what I don't want. What can I do here? I was thinking I could enable the user www-data to login as sftp, so that it'll be able to modify files/dirs that www-data owns in /var/www. But for some reason I think this would be a stupid move securitywise.

  • PHP classes, parse syntax errors when using 'var' to declare variables

    - by jon
    I am a C# guy trying to translate some of my OOP understanding over to php. I'm trying to make my first class object, and are hitting a few hitches. Here is the beginning of the class: <?php require("Database/UserDB.php"); class User { private var $uid; private var $username; private var $password; private var $realname; private var $email; private var $address; private var $phone; private var $projectArray; public function _construct($username) { $userArray = UserDB::GetUserArray($username); $uid = $userArray['uid']; $username = $userArray['username']; $realname = $userArray['realname']; $email = $userArray['email']; $phone = $userArray['phone']; $i = 1; $projectArray = UserDB::GetUserProjects($this->GetID()); while($projectArray[$i] != null) { $projectArray[$i] = new Project($projectArray[$i]); } UserDB.php is where I have all my static functions interacting with the Database for this User Class. I am getting errors using when I use var, and I'm getting confused. I know I don't HAVE to use var, or declare the variables at all, but I feel it is a better practice to do so. the error is "unexpected T_VAR, expecting T_VARIABLE" When I simply remove var from the declarations it works. Why is this?

  • Outlook.com Sweep rule vs Filter rule

    - by Mahesha999
    New outlook.com introduced new sweep option. With it, you can create a filter to move messages from particular sender to a particular folder after certain days the mail comes. This rules gets added to the Filter list. However we cannot edit this rule by clicking Edit in front of it in that list. The dialog appears saying you should delete the rule and create the new one. I don't understand why sweep rules are considered differently from Filter rules? I have 68 filter rules. What if I want to add such time clause to these filter rules so that instead of moving the incoming mails immediately to a certain folder, they will be kept in Inbox for say 10 days and then they will be moved. Such time clause cannot be added to the filter rules. So should I delete all these 68 filters and create new Sweep rules?

    Hey guys for a while now I have been trying to come up with a method that can filter PHP results for listing items using JS. Look at these examples: http://www.autotrader.co.uk/search/used/cars/ http://www.vcars.co.uk/used-cars/ You will notice that the actual filter uses JavaScript however my question is how does it query the database to bring back the results? It obviously using PHP however how does the JS control what the PHP drags from the DB? Thanks

  • Using Dynamic LINQ to get a filter for my Web API

    - by Espo
    We are considering using the Dynamic.CS linq-sample included in the "Samples" directory of visual studio 2008 for our WebAPI project to allow clients to query our data. The interface would be something like this (In addition to the normal GET-methods): public HttpResponseMessage List(string filter = null); The plan is to use the dynamic library to parse the "filter"-variable and then execute the query agains the DB. Any thoughts if this is a good idea? Is it a security problem?

  • what service to restart for /var/log/auth.log to start

    - by Bond
    Here is a situation since the log files on my server had grown to several Gigabytes I took a backup of directory /var/log and then manually when to each subdirectory of /var/log and the files which were big in size I did cat > /var/log/file_which_is_big press 2 times enter key (basically over wrote those files with a blank space) and then Ctrl+C So basically I over wrote those files to be blank. Now when I open /var/log/auth.log I don't see any entry (which is expected also since I over wrote) but when I exit the SSH session and login again then also I do not see any entry in auth.log is there any way other than rebooting the machine to make sure I keep getting the entries in /var/log/auth.log I am not sure which service writes in this file. This is a Ubuntu 10.04 server.

  • Is there a learnable filter in Thunderbird for non-spam messages (as in Opera Mail)?

    - by Debilski
    One feature I like very much about Opera Mail is that you can have learnable filters for any purpose. So not only can you filter spam messages but also messages that your friends sent you or info mails from web platforms without having to enter each and every mail address you want to filter. It actually works quite satisfying and you can combine it with string filtering, too. It does a few mistakes in the beginning but then improves quickly after you have removed some of the false positives. However, there are a couple of drawbacks with the Opera Mail module. The filters are only ‘virtual’. So, with IMAP there is no easy way of mirroring the filtered structure back on the server and when I’m using webmail I’ll see the whole unfiltered mess in the inbox folder. Opera’s not using the OS X address book — and neither does it use ldap (which is not too important for me at the moment). So, I’m not specifically looking for a Thunderbird solution here, a way to fix things in Opera or Apple Mail should do as well. Or some other E-Mail program I don’t even know about yet. (So, to be clear, I’d like to have: OS X Address Book integration, Learnable filters for any type of filtering, Ability to push filtered folder structure to the IMAP server) But I thought like, if it is possible then most probably there would be an add-on for Thunderbird available. Any ideas?

  • Help with Nicedit - removeFormat function
