  • nginx serving php for download (previously: nginx multiple location alias 404)

    - by torsten
    Im having issues with the alias location in the following configuration server { listen 80; server_name localhost; root /srv/http/share; index index.php; include php.conf; location / { try_files $uri $uri/ /index.php$is_args$args; } location /phpmemcachedadmin { alias /srv/http/phpmemcachedadmin; } location /webgrind { alias /srv/http/webgrind; } } while / works well, im getting a 404 for /webgrind and /phpmemcachedadmin. If i switch the root directory to /srv/http and alias the / location, die /phpmemcachedadmin and webgrind work, but not the / location. UPDATE: I managed the probems getting all location to work, so here is the updated config #user html; worker_processes 2; #error_log logs/error.log; #error_log logs/error.log notice; #error_log logs/error.log info; #pid logs/nginx.pid; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; gzip on; server { listen 80; server_name localhost; location / { root /srv/http/share; index index.php; try_files $uri $uri/ /index.php$is_args$args; include php.conf; } location /phpmemcachedadmin { root /srv/http; index index.php; try_files $uri $uri/ /index.php$is_args$args; include php.conf; } location /webgrind { root /srv/http; index index.php; try_files $uri $uri/ /index.php$is_args$args; include php.conf; } } } The php.conf looks like this: location ~ \.php$ { try_files $uri =404; fastcgi_pass unix:/run/php-fpm/php-fpm.sock; fastcgi_index index.php; include fastcgi.conf; } while the fastcgi.conf like this: fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_param SCRIPT_NAME $fastcgi_script_name; fastcgi_param REQUEST_URI $request_uri; fastcgi_param DOCUMENT_URI $document_uri; fastcgi_param DOCUMENT_ROOT $document_root; fastcgi_param SERVER_PROTOCOL $server_protocol; fastcgi_param HTTPS $https if_not_empty; fastcgi_param GATEWAY_INTERFACE CGI/1.1; fastcgi_param SERVER_SOFTWARE nginx/$nginx_version; fastcgi_param REMOTE_ADDR $remote_addr; fastcgi_param REMOTE_PORT $remote_port; fastcgi_param SERVER_ADDR $server_addr; fastcgi_param SERVER_PORT $server_port; fastcgi_param SERVER_NAME $server_name; # PHP only, required if PHP was built with --enable-force-cgi-redirect fastcgi_param REDIRECT_STATUS 200; But there is a problem serving phpmemcachedadmin. If i call localhost/phpmemcachedadmin/index.php it works quite well (i get a log that i got served the file in access log). On the other hand, if i just call localhost/phpmemcachedadmin/ he serves me the file for download. Neither the error.log nor the access.log log anything when i get served the the file for download. Any ideas?

  • How can I rebuild the index in Thunderbird 3.0?

    - by Martin
    Hello, I have just deleted a lot of old messages (about 3,000) from my Thunderbird 3.0 profile. When I now use the new search feature (search all messages), TB still finds the deleted ones. I deleted them this way: I moved the messages to an own "archive" folder (not the built-in archive feature). Then I stopped TB and moved the archive files and folders to a different place on my file system. Then restarted TB. I archive my messages this way for years now. So, it seems that Thunderbird does not notice the deletion of my messages, thus the index is not updated. How can I tell TB to instantly rebuild the index?

  • Why isn't this rewrite rule (nginx) applied? (trying to setup Wordpress multisite)

    - by Brian Park
    Hi, I'm trying to setup Wordpress multisite (subfolder structure) with nginx, but having a problem with this rewrite rule. Below is the Apache's .htaccess, which I have to translate into nginx configuration. RewriteEngine On RewriteBase /blogs/ RewriteRule ^index\.php$ - [L] # uploaded files RewriteRule ^([_0-9a-zA-Z-]+/)?files/(.+) wp-includes/ms-files.php?file=$2 [L] # add a trailing slash to /wp-admin RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L] RewriteCond %{REQUEST_FILENAME} -f [OR] RewriteCond %{REQUEST_FILENAME} -d RewriteRule ^ - [L] RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L] RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L] RewriteRule . index.php [L] Below is what I came up with: server { listen 80; server_name example.com; server_name_in_redirect off; expires 1d; access_log /srv/www/example.com/logs/access.log; error_log /srv/www/example.com/logs/error.log; root /srv/www/example.com/public; index index.html; try_files $uri $uri/ /index.html; # rewriting uploaded files rewrite ^/blogs/(.+/)?files/(.+) /blogs/wp-includes/ms-files.php?file=$2 last; # add a trailing slash to /wp-admin rewrite ^/blogs/(.+/)?wp-admin$ /blogs/$1wp-admin/ permanent; if (!-e $request_filename) { rewrite ^/blogs/(.+/)?(wp-(content|admin|includes).*) /blogs/$2 last; rewrite ^/blogs/(.+/)?(.*\.php)$ /blogs/$2 last; } location /blogs/ { index index.php; #try_files $uri $uri/ /blogs/index.php?q=$uri&$args; } location ~ \.php$ { include /etc/nginx/fastcgi_params; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /srv/www/example.com/public$fastcgi_script_name; } # static assets location ~* ^.+\.(manifest)$ { access_log /srv/www/example.com/logs/static.log; } location ~* ^.+\.(ico|ogg|ogv|svg|svgz|eot|otf|woff|mp4|ttf|css|rss|atom|js|jpg|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|ppt|tar|mid|midi|wav|bmp|rtf)$ { # only set expires max IFF the file is a static file and exists if (-f $request_filename) { expires max; access_log /srv/www/example.com/logs/static.log; } } } In the above code, I believe rewrite ^/blogs/(.+/)?(.*\.php)$ /blogs/$2 last; has no effect because when I look at the access_log file, I see the following line: 2010/09/15 01:14:55 [error] 10166#0: *8 "/srv/www/example.com/public/blogs/test/index.php" is not found (2: No such file or directory), request: "GET /blogs/test/ HTTP/1.1" (Here, 'test' is the second blog created using multisite feature) What I'm expecting is that /blogs/test/index.php gets rewritten to /blogs/index.php, but it doesn't seem to do that... Am I overlooking something obvious? Thanks!

  • Require and Includes not Functioning Nginx Fpm/FastCGI

    - by Vince Kronlein
    I've split up my FPM pools so that php will run under each individual user and set the routing correctly in my vhost.conf files to pass the proper port number. But I must have something incorrect in my environment because on this new domain I set up, require, require_once, include, include_once do not function, or rather, they may not be getting passed up to the interpreter to be rendered as php. Since I already have a Wordpress install on this server that runs perfectly, I'm pretty sure the error is in my server block for nginx. server { server_name www.domain.com; rewrite ^(.*) http://domain.com$1 permanent; } server { listen 80; server_name domain.com; client_max_body_size 500M; index index.php index.html index.htm; root /home/username/public_html; location / { try_files $uri $uri/ index.php; } location ~ \.php$ { if (!-e $request_filename) { rewrite ^(.*)$ /index.php?name=$1 break; } fastcgi_pass 127.0.0.1:9002; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } location ~ /\.ht { deny all; } } The problem I'm finding I think is that there are dynamic calls to the doc root index file, while all calls to anything within a sub-folder should be routed as normal ie: NOT passed to index.php. I can't seem to find the right mix here. It should run like so: domain.com/cindy (file doesn't exist) --> index.php?name=$1 domain.com/admin/anyfile.php (files DO exist) --> admin/anyfile.php?$args

  • On Windows machines, what is the typical toolchain for remote maintenance?

    - by Hanno Fietz
    I need to deploy PHP and Python code and the appropriate environment (web server, db server) to remote Windows systems, and I don't know what toolchain would be the equivalent to ssh, scp, bash and the like. So, basically, what I need to be able to do is the following: access remote Windows with the appropriate privileges in a secure manner, like I routinely do with ssh (I don't even know whether that would be a text or graphic interface on Windows). remotely install software: Apache or IIS, MySQL or Postgres, Python or PHP copy files from remote (the application we're deploying) remotely configure the machine to run regular tasks (e. g. checking for updates to the application) automate tasks like downloading files from a designated place The main question is probably how I get onto the machine securely in the first place, and then the rest is general Windows admin knowledge, which probably is too broad a scope to fit into one question. I have years of experience with maintaining Linux boxes and I have used tools of varying sophistication on those, ranging from plain scping of PHP files to deployment of Java application containers and even full VMs with Vagrant. On Windows, I'm a complete noob, and I don't even know where to start. I have installed Apache, MySQL , PHP on a desktop machine maybe twice in my life, that's about it. Bonus points for things that work from a Linux machine at my end, but I could run a VM and do everything from there.

  • How do I update the memberOf attributes of existing objects after adding the OpenLDAP Reverse Group Membership Maintenance overlay?

    - by mss
    This is a follow-up to this question: I added the memberof overlay to an existing OpenLDAP 2.4 server. Now I want to update the existing user objects. For new group memberships, the memberOf attribute is updated correctly. But I have a bunch of existing groups which aren't updated automatically. I could remove all users from their groups and re-add them to make sure these entries are in sync. Since this is a Univention Corporate Server which does a lot of magic when you modify the LDAP, I don't want to risk breaking my directory. Is there a way to trick the overlay to update these operational attributes?

  • nginx virtual hosts are not working, all vhosts goes to the default one

    - by Adirael
    Hello, I just did a clean install of nginx + php-fpm on a VPS running Ubuntu 10.10, nginx is serving and PHP is working fine, but I'm not able to add vhosts to it. Well, I can add them, but only one works, the rest go to this first one. This is my first vhost, for host1: server { listen 80; server_name host1; access_log /var/log/nginx/host1.log; error_log /var/log/nginx/host1.error.log; location / { root /var/www/vhosts/host1/; index index.html index.htm index.php; } location ~ \.php$ { include /etc/nginx/fastcgi_params; #fastcgi_pass 127.0.0.1:9000; fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_param SCRIPT_FILENAME /var/www/vhosts/host1/$fastcgi_script_name; fastcgi_param PATH_INFO $fastcgi_script_name; fastcgi_index index.php; } } And the second one, for host2: server { listen 80; server_name host2; access_log /var/log/nginx/host2.log; error_log /var/log/nginx/host2.error.log; location / { root /var/www/vhosts/host2/; index index.html index.htm index.php; } location ~ \.php$ { include /etc/nginx/fastcgi_params; #fastcgi_pass 127.0.0.1:9000; fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_param SCRIPT_FILENAME /var/www/vhosts/host2/$fastcgi_script_name; fastcgi_param PATH_INFO $fastcgi_script_name; fastcgi_index index.php; } } The problem is, when I go to http://host1 everything is fine, but on http://host2, it just shows host1! I don't have Apache installed and everything comes from repos. Any pointers?

  • cakephp & nginx config/rewrite rules

    - by seanl
    Hi somebody please help me out, I've asked this at stackoverflow as well but not got much of a response and was debating whether it was programming or server related. I’m trying to setup a cakephp environment on a Centos server running Nginx with Fact CGI. I already have a wordpress site running on the server and a phpmyadmin site so I have PHP configured correctly. My problem is that I cannot get the rewrite rules setup correct in my vhost so that cake renders pages correctly i.e. with styling and so on. I’ve googled as much as possible and the main consensus from the sites like the one listed below is that I need to have the following rewrite rule in place location / { root /var/www/sites/somedomain.com/current; index index.php index.html; # If the file exists as a static file serve it # directly without running all # the other rewrite tests on it if (-f $request_filename) { break; } if (!-f $request_filename) { rewrite ^/(.+)$ /index.php?url=$1 last; break; } } http://blog.getintheloop.eu/2008/4/17/nginx-engine-x-rewrite-rules-for-cakephp problem is these rewrite assume you run cake directly out of the webroot which is not what I want to do. I have a standard setup for each site i.e. one folder per site containing the following folders log, backup, private and public. Public being where nginx is looking for its files to serve but I have cake installed in private with a symlink in public linking back to /private/cake/ this is my vhost server { listen 80; server_name app.domain.com; access_log /home/public_html/app.domain.com/log/access.log; error_log /home/public_html/app.domain.com/log/error.log; #configure Cake app to run in a sub-directory #Cake install is not in root, but elsewhere and configured #in APP/webroot/index.php** location /home/public_html/app.domain.com/private/cake { index index.php; if (!-e $request_filename) { rewrite ^/(.+)$ /home/public_html/app.domain.com/private/cake/$1 last; break; } } location /home/public_html/app.domain.com/private/cake/ { index index.php; if (!-e $request_filename) { rewrite ^/(.+)$ /home/public_html/app.domain.com/public/index.php?url=$1 last; break; } } # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /home/public_html/app.domain.com/private/cake$fastcgi_script_name; include /etc/nginx/fastcgi_params; } } Now like I said I can see the main index.php of cake and have connected it to my DB but this page is without styling so before I proceed any further I would like to configure it correctly. What am I doing wrong………. Thanks seanl

  • How do I configure Reverse Group Membership Maintenance on an openldap server? (memberOf)

    - by emills
    I am currently working on integrating LDAP authentication into a system and I would like to restrict access based on LDAP group. The only way to do this is via a search filter and therefore I believe my only option to be the use of the "memberOf" attribute in my search filter. It is my understanding that the "memberOf" attribute is an operational attribute which can be created by the server for me anytime a new "member" attribute is created for any "groupOfNames" entry on the server. My main goal is to be able to add a "member" attribute to an existing "groupOfNames" entry and have a matching "memberOf" attribute be added to the DN I provide. What I have managed to achieve so far: I'm still pretty new to LDAP administration but based on what I found in the openldap admin's guide, it looks like Reverse Group Membership Maintence aka "memberof overlay" would achieve exactly the effect I am looking for. My server is currently running a package installation (slapd on ubuntu) of openldap 2.4.15 which uses "cn=config" style runtime configuration. Most of the examples I have found still reference the older "slapd.conf" method of static configuration and I have tried my best to adapt the configurations to the new directory based model. I have added the following entries to enable the memberof overlay module: Enable the module with olcModuleLoad cn=config/cn\=module\{0\}.ldif dn: cn=module{0} objectClass: olcModuleList cn: module{0} olcModulePath: /usr/lib/ldap olcModuleLoad: {0}back_hdb olcModuleLoad: {1}memberof.la structuralObjectClass: olcModuleList entryUUID: a410ce98-3fdf-102e-82cf-59ccb6b4d60d creatorsName: cn=config createTimestamp: 20090927183056Z entryCSN: 20091009174548.503911Z#000000#000#000000 modifiersName: cn=admin,cn=config modifyTimestamp: 20091009174548Z Enabled the overlay for the database and allowed it to use it's default settings (groupOfNames,member,memberOf,etc) cn=config/olcDatabase={1}hdb/olcOverlay\=\{0\}memberof dn: olcOverlay={0}memberof objectClass: olcMemberOf objectClass: olcOverlayConfig objectClass: olcConfig objectClass: top olcOverlay: {0}memberof structuralObjectClass: olcMemberOf entryUUID: 6d599084-490c-102e-80f6-f1a5d50be388 creatorsName: cn=admin,cn=config createTimestamp: 20091009104412Z olcMemberOfRefInt: TRUE entryCSN: 20091009173500.139380Z#000000#000#000000 modifiersName: cn=admin,cn=config modifyTimestamp: 20091009173500Z My current result: By using the above configuration, I am able to add a NEW "groupOfNames" with any number of "member" entries and have all the involved DNs updated with a "memberOf" attribute. This is part of the behavior I would expect. While I believe the following should have been accomplished with the memberof overlay, I still do not know how to do the following and I would gladly welcome any advice: Add a "member" attribute to an EXISTING "groupOfNames" and have a corresponding "memberOf" attribute be created automatically. Remove a "member" attribute and have the corresponding "memberOf" attribute" be removed automatically.

  • How to get XML into a Dictionary with an Expression?

    - by DaveDev
    I have the following XML: <PerformancePanel page="PerformancePanel.ascx" title=""> <FundGroup heading="Net Life Managed Funds"> <fund id="17" countryid="N0" index="24103723" /> <fund id="81" countryid="N0" index="24103723" /> <fund id="127" countryid="N0" index="24103722" /> <fund id="345" countryid="N0" index="24103723" /> <fund id="346" countryid="N0" index="24103723" /> </FundGroup> <FundGroup heading="Net Life Specialist Funds"> <fund id="110" countryid="N0" index="24103717" /> <fund id="150" countryid="N0" index="24103719" /> <fund id="119" countryid="N0" index="24103720" /> <fund id="115" countryid="N0" index="24103727" /> <fund id="141" countryid="N0" index="24103711" /> <fund id="137" countryid="N0" /> <fund id="146" countryid="N0" /> <fund id="133" countryid="N0" /> <fund id="90" countryid="N0" /> <fund id="104" countryid="N0" /> <fund id="96" countryid="N0" /> </FundGroup> </PerformancePanel> I can get the data into an anonymous object as follows: var offlineFactsheet = new { PerformancePanels = (from panel in doc.Elements("PerformancePanel") select new PerformancePanel { PerformanceFunds = (from fg in panel.Elements("FundGroup") select new { Heading = (fg.Attribute("heading") == null) ?

I'd like to have a Dictionary() where each header text is the key to the list of funds under it. I'm having difficulty applying the example in the linked question because that only returns a string, and this needs to return the dictionary. This is the point that I got to before it occurred to me that I'm lost!!!: this.PerformancePanels = doc.Elements("PerformancePanel").Select(e => { var control = (PerformancePanel)LoadControl(this.OfflineFactsheetPath + (string)e.Attribute("page")); control.PerformanceFunds = e.Elements("FundGroup").Select(f => { List<Fund> funds = (from fund in e.Elements("fund") select new Fund { FundId = (int)fund.Attribute("id"), CountryId = (string)fund.Attribute("countryid"), FundIndex = (fund.Attribute("index") == null) ? null : new Index { Id = (int)fund.Attribute("index") }, FundNameAppend = (fund.Attribute("append") == null) ? "" : (string)fund.Attribute("append") }).ToList(); string heading = (e.Attribute("heading") == null) ? "" : (string)e.Attribute("heading"); }).ToDictionary(xx => heading, xx => Funds); return control; }).ToList(); Could someone point me in the right direction please? I'm not even sure if 'Expression' is the right terminology. Could someone fill me in on that too? Thanks.

  • Using SharePoint PeoplePicker control in custom ASP.NET pages

    - by Jignesh Gangajaliya
    I was developing custom ASP.NET page for a SharePoint project, and the page uses SharePoint PeoplePicker control. I needed to manipulate the control on the client side based on the user inputs. PeoplePicker Picker is a complex control and the difficult bit is that it contains many controls on the page (use the page source viewer to see the HTML tags generated). So getting into the right bit is tricky and also the default JavaScript functions like, control.disabled; control.focus(); will not work with PeoplePicker control. After some trial and error I came up with the solution to manipulate the control using JavaScript.  Here I am posting the JavaScript code snippet to enable/disable the PeoplePicker Control: function ToggleDisabledPeoplePicker(element, isDisabled) {     try     {         element.disabled = isDisabled;     }            catch(exception)     {}            if ((element.childNodes) && (element.childNodes.length > 0))     {         for (var index = 0; index < element.childNodes.length; index++)         {             ToggleDisabledPeoplePicker(element.childNodes[index], isDisabled);         }     } } // to disable the control ToggleDisabledPeoplePicker(document.getElementById("<%=txtMRA.ClientID%>"), true); The script shown below can be used to set focus back to the PeoplePicker control from custom JavaScript validation function: var found = false;         function SetFocusToPeoplePicker(element) {     try     {         if (element.id.lastIndexOf("upLevelDiv") !=-1)         {             element.focus();             found = true;             return;         }     }             catch(exception)     {}             if ((element.childNodes) && (element.childNodes.length > 0))     {         for (var index = 0; index < element.childNodes.length; index++)         {             if (found)             {                 found = false;                 break;             }                      SetFocusToPeoplePicker(element.childNodes[index]);         }     } } - Jignesh

  • Apache htaccess results in files being downloaded instead of displayed

    - by chrissik
    So I had this "beautiful" website that did exactly what I wanted it to do. Then I shut down my PC, reboot and...the pages just download now instead of being displayed. I re-installed XAMPP and launched Apache again and I was able to identify the .htaccess file as the cause of the problem. Options +FollowSymlinks RewriteEngine on RewriteCond %{QUERY_STRING} !^desktop RewriteCond %{HTTP_USER_AGENT} "android|blackberry|googlebot-mobile|iemobile|iphone|ipod|#opera mobile|palmos|webos" [NC] RewriteRule ^/?$ /mobile/index [L,R=302] RewriteRule ^/?$ /de/index [R] RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME}\.html -f RewriteRule ^(.*)$ $1.html Here is the problem I guess: RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME}\.html -f RewriteRule ^(.*)$ $1.html This should make it possible to use /de/index instead of /de/index.html - but somehow it causes the page to download if I open localhost/de/index (but with localhost/de/index.html it works fine...). I'm using HTML Sites with SSI Elements on a Apache web server. The only other file that is different to the out-of-the-box ones is the httpd.conf, where I enabled SSI: AddType text/html .shtml AddHandler server-parsed .shtml AddHandler server-parsed .html AddHandler server-parsed .htm Options Indexes FollowSymLinks Includes AddOutputFilter INCLUDES .shtml Options +Includes So I hope there is somebody among you that can help me with this annoying problem as I'm quite desperate... for some reason, even without the problematic lines Chrome keeps downloading the files (even if I delete the .htaccess file), while IE and Opera display the pages. Edit: Now Opera also wants to download files (whether index.html or index are called).

  • How do you set up the directory structure for a multilingual site without duplicating content?

    - by Ricardo
    I want to make a website in two languages. I've looked around and settled on the directory option of separating both languages. How do I make it work? Let's say I have the following three files for the landing homepage, the English page and the Spanish page: http://www.domain.com/index.html http://www.domain.com/en/index.html http://www.domain.com/es/index.html Let's also say that /index.html will be in English, with a link to /es/index.html. In turn, /es/index.html will have a link to the English version. Would this be back to /index.html or to /en/index.html. How do I get both English versions (the one at the root and the one in the directory) to actually be the same file in the same directory? I'm new to this, so I'm not using any scripts yet. To me, the obvious solution is to duplicate both English versions and have the one at the root point to files under the /en/ directory, but I'm not a fan of duplication and I've learned that search engines really frown upon that. Anyone point me in the right direction?

  • Image mapping using lookup tables [on hold]

    - by jblasius
    I have an optimization problem. I'm using a look-up table to map a pixel in an image: for (uint32_t index = 0u; index < imgSize; index++) { img[ lt[ index ] ] = val; } Is there a faster way to do this, perhaps using a reinterpret_cast or something like that? I am accessing two different memory addresses, so what is the compiler doing? One solution is to do a set of reads to access adjacent memory addresses. struct mblock { uint32_t buf[10u]; }; mblock mb; for (uint32_t index = 0u; index < imgSize; index += 10u) { mb = *reinterpret_cast<mblock*>(lt + index)); for (uint8_t i = 0u; i < 10u; i ++) { mb.buf[i] += img; } for (uint8_t i = 0u; i < 10u; i ++) { *( mb.buf[i] ) = val; } } This speeds up the code because I'm separating the image access from the table look-up; the positions in the look-up table are adjacent. I still get the image access problem as it is accessing random address positions.

The problem already was solved in a very bad way, but I need to fix it quickly. Anyone knows some tricks to debug better it without open the frameworks code? Cheers, Felipe

  • How do I automatically rebuild the Sphinx index under django-sphinx?

    - by Apreche
    I just setup django-sphinx, and it is working beautifully. I am now able to search my model and get amazing results. The one problem is that I have to build the index by hand using the indexer command. That means every time I add new content, I have to manually hit the command line to rebuild the search index. That is just not acceptable. I could make a cron job that automatically runs the indexer command every so often, but that's far from optimal. New data won't be indexed until the cron runs again. In addition, the indexer will run unnecessarily most times as my site doesn't have data being added very often. How do I set it up so that the Sphinx index will automatically rebuild itself whenever data is added to or modified in a searchable django model?

  • std::deque: How do I get an iterator pointing to the element at a specified index?

    - by Ptah- Opener of the Mouth
    I have a std::deque, and I want to insert an element at a specified index (I'm aware that std::list would be better at this). The deque::insert() function takes an iterator to specify the location to insert. Given an index, how can I get an iterator pointing to that location, so that I can pass that iterator to insert()? For example: void insertThing ( deque<Thing> & things, Thing thing, size_t index ) { deque<Thing>::iterator it = /* what do I do here? */ things.insert ( it, thing ); } I'm sure this is a very basic question, and I apologize for it. It's been a long time since I've used the STL, and I don't see anything in std::deque's member list that obviously does what I want. Thanks.

  • How to force oracle to use index range scan?

    - by wsb3383
    Hi, all. I have a series of extremely similar queries that I run against a table of 1.4 billion records (with indexes), the only problem is that at least 10% of those queries take 100x more time to execute than others. I ran an explain plan and noticed that the for the fast queries (roughly 90%) Oracle is using an index range scan (on my created), while on the slow one, it's using a full index scan. Is there a way to force Oracle to do a an index range scan? Thanks!

  • Model Binding to a List using non-sequential indexes. Can I access the index later?

    - by Kid A
    I'm following Phil's great tutorial on model binding to a list. I use input names like this: book[5804].title book[5804].author book[1234].title book[1234].author This works well and the data gets back to the model just fine, populating a list of books. What I'm looking for is a way to get access in the model to the index that was used to send the books. I'd like to get that number, "5804." This is because the index is of semantic importance. If I can access it, it saves me from setting another property on the object (book ID). Is there a way to see, either on the FormCollection or on the model after UpdateModel is called, what the index was when it was sent up?

  • How to index a string like "aaa.bbb.ddd-fff" in Lucene?

    - by user46703
    Hi, I have to index a lot documents that contain reference numbers like "aaa.bbb.ddd-fff". The structure can change but it's always some arbitrary numbers or characters combined with "/","-","_" or some other delimiter. The users want to be able to search for any of the substrings like "aaa" or "ddd" and also for combinations like "aaa.bbb" or "ddd-fff". The best I have been able to come up with is to create my own token filter modeled after the synonym filter in "Lucene in action" which spits out multiple terms for each input. In my case I return "aaa.bbb", "bbb.ddd","bbb.ddd-fff" and all other combinations of the substrings. This works pretty well but when I index large documents (100MB) that contain lots of such strings I tend to get out of memory exceptions because my filter returns multiple terms for each input string. Is there a better way to index these strings?

    - by adam
    On stackoverflow in the users profile area there are many tabs which all display differing information such as questions asked and graphs. Its the same view though and im wondering hows its best to achieve this in rails whilst keeping the controller skinny and logic in the view to a minimum. def index @user = current_user case params[:tab_selected] when "questions" @data = @user.questions when "answers" @sentences = @user.answers else @sentences = @user.questions end respond_to do |format| format.html # index.html.erb nd end but how do i process this in the index view without a load of if and else statments. And if questions and answers are presented differently whats the best way to go about this.

  • Cake PHP Error: Make sure you have created index.ctp (???)

    - by Louis Stephens
    I was just starting to learn cakephp today by going through a "blog tutorial". I created my blog_controller.php and then created a folder named 'blog' with the apps/views/ structure. The next step in the tutorial was to create the index.ctp file within the blog folder under views. In the tutorial it declares that all error messages should be gone. However, I still receive an error message: Error: The view for BlogController::index() was not found. Error: Confirm you have created the file: /Users/trippstephens/Dropbox/cakephp-cakephp1x-348e5f0/app/views/blog/index.ctp For the life of me, I can not figure out what I have done wrong. I am running cakephp under MAMP and it "installed" successfully. Any help would be appreciated.

  • In SQL Server 2008, when would I use a full text index that covered several tables?

    - by Suddy
    I wanted to do a full text search across several related tables in SQL Server 2008. From browsing this site I've realised the best option is via a view, but initially I thought I was meant to add several tables to the same full text index via Management Studio. I started to do this and realised the index would have no idea how they were related, so my question is: when would I want to have a full text index covering several tables in this way? Apologies for the vagueness, I am just trying to satisfy my curiosity after Google let me down.

  • MySQL sorting: NULL to the end & use index? Not possible?

    - by Vojto
    Hello fellow experts, I have a huge table and I want simple sorting. It could be so easy. I could just create an index and do some really fast sorting thanks to that index. But my client wants to put NULLs to the end, which is complicates the whole situation. Instead of simple: SORT BY name ASC I have to do SORT BY name IS NULL ASC, name ASC. That would be ok, but it because of that my index is useless, and the sorting is very slow. I don't know if there's a way to solve this problem, but if there is one, I desperately ask for help. :'(
