  • C#/.NET Little Wonders: Interlocked Read() and Exchange()

    - by James Michael Hare
    Once again, in this series of posts I look at the parts of the .NET Framework that may seem trivial, but can help improve your code by making it easier to write and maintain. The index of all my past little wonders posts can be found here. Last time we discussed the Interlocked class and its Add(), Increment(), and Decrement() methods which are all useful for updating a value atomically by adding (or subtracting).  However, this begs the question of how do we set and read those values atomically as well? Read() – Read a value atomically Let’s begin by examining the following code: 1: public class Incrementor 2: { 3: private long _value = 0; 4:  5: public long Value { get { return _value; } } 6:  7: public void Increment() 8: { 9: Interlocked.Increment(ref _value); 10: } 11: } 12:  It uses an interlocked increment, as we discuss in my previous post (here), so we know that the increment will be thread-safe.  But, to realize what’s potentially wrong we have to know a bit about how atomic reads are in 32 bit and 64 bit .NET environments. When you are dealing with an item smaller or equal to the system word size (such as an int on a 32 bit system or a long on a 64 bit system) then the read is generally atomic, because it can grab all of the bits needed at once.  However, when dealing with something larger than the system word size (reading a long on a 32 bit system for example), it cannot grab the whole value at once, which can lead to some problems since this read isn’t atomic. For example, this means that on a 32 bit system we may read one half of the long before another thread increments the value, and the other half of it after the increment.  To protect us from reading an invalid value in this manner, we can do an Interlocked.Read() to force the read to be atomic (of course, you’d want to make sure any writes or increments are atomic also): 1: public class Incrementor 2: { 3: private long _value = 0; 4:  5: public long Value 6: { 7: get { return Interlocked.Read(ref _value); } 8: } 9:  10: public void Increment() 11: { 12: Interlocked.Increment(ref _value); 13: } 14: } Now we are guaranteed that we will read the 64 bit value atomically on a 32 bit system, thus ensuring our thread safety (assuming all other reads, writes, increments, etc. are likewise protected).  Note that as stated before, and according to the MSDN (here), it isn’t strictly necessary to use Interlocked.Read() for reading 64 bit values on 64 bit systems, but for those still working in 32 bit environments, it comes in handy when dealing with long atomically. Exchange() – Exchanges two values atomically Exchange() lets us store a new value in the given location (the ref parameter) and return the old value as a result. So just as Read() allows us to read atomically, one use of Exchange() is to write values atomically.  For example, if we wanted to add a Reset() method to our Incrementor, we could do something like this: 1: public void Reset() 2: { 3: _value = 0; 4: } But the assignment wouldn’t be atomic on 32 bit systems, since the word size is 32 bits and the variable is a long (64 bits).  Thus our assignment could have only set half the value when a threaded read or increment happens, which would put us in a bad state. So instead, we could write Reset() like this: 1: public void Reset() 2: { 3: Interlocked.Exchange(ref _value, 0); 4: } And we’d be safe again on a 32 bit system. But this isn’t the only reason Exchange() is valuable.  The key comes in realizing that Exchange() doesn’t just set a new value, it returns the old as well in an atomic step.  Hence the name “exchange”: you are swapping the value to set with the stored value. So why would we want to do this?  Well, anytime you want to set a value and take action based on the previous value.  An example of this might be a scheme where you have several tasks, and during every so often, each of the tasks may nominate themselves to do some administrative chore.  Perhaps you don’t want to make this thread dedicated for whatever reason, but want to be robust enough to let any of the threads that isn’t currently occupied nominate itself for the job.  An easy and lightweight way to do this would be to have a long representing whether someone has acquired the “election” or not.  So a 0 would indicate no one has been elected and 1 would indicate someone has been elected. We could then base our nomination strategy as follows: every so often, a thread will attempt an Interlocked.Exchange() on the long and with a value of 1.  The first thread to do so will set it to a 1 and return back the old value of 0.  We can use this to show that they were the first to nominate and be chosen are thus “in charge”.  Anyone who nominates after that will attempt the same Exchange() but will get back a value of 1, which indicates that someone already had set it to a 1 before them, thus they are not elected. Then, the only other step we need take is to remember to release the election flag once the elected thread accomplishes its task, which we’d do by setting the value back to 0.  In this way, the next thread to nominate with Exchange() will get back the 0 letting them know they are the new elected nominee. Such code might look like this: 1: public class Nominator 2: { 3: private long _nomination = 0; 4: public bool Elect() 5: { 6: return Interlocked.Exchange(ref _nomination, 1) == 0; 7: } 8: public bool Release() 9: { 10: return Interlocked.Exchange(ref _nomination, 0) == 1; 11: } 12: } There’s many ways to do this, of course, but you get the idea.  Running 5 threads doing some “sleep” work might look like this: 1: var nominator = new Nominator(); 2: var random = new Random(); 3: Parallel.For(0, 5, i => 4: { 5:  6: for (int j = 0; j < _iterations; ++j) 7: { 8: if (nominator.Elect()) 9: { 10: // elected 11: Console.WriteLine("Elected nominee " + i); 12: Thread.Sleep(random.Next(100, 5000)); 13: nominator.Release(); 14: } 15: else 16: { 17: // not elected 18: Console.WriteLine("Did not elect nominee " + i); 19: } 20: // sleep before check again 21: Thread.Sleep(1000); 22: } 23: }); And would spit out results like: 1: Elected nominee 0 2: Did not elect nominee 2 3: Did not elect nominee 1 4: Did not elect nominee 4 5: Did not elect nominee 3 6: Did not elect nominee 3 7: Did not elect nominee 1 8: Did not elect nominee 2 9: Did not elect nominee 4 10: Elected nominee 3 11: Did not elect nominee 2 12: Did not elect nominee 1 13: Did not elect nominee 4 14: Elected nominee 0 15: Did not elect nominee 2 16: Did not elect nominee 4 17: ... Another nice thing about the Interlocked.Exchange() is it can be used to thread-safely set pretty much anything 64 bits or less in size including references, pointers (in unsafe mode), floats, doubles, etc.  Summary So, now we’ve seen two more things we can do with Interlocked: reading and exchanging a value atomically.  Read() and Exchange() are especially valuable for reading/writing 64 bit values atomically in a 32 bit system.  Exchange() has value even beyond simply atomic writes by using the Exchange() to your advantage, since it reads and set the value atomically, which allows you to do lightweight nomination systems. There’s still a few more goodies in the Interlocked class which we’ll explore next time! Technorati Tags: C#,CSharp,.NET,Little Wonders,Interlocked

  • Apache sends plain-text response when accessing SSL-enabled site without HTTPS

    - by animuson
    I've never encountered something such as this before. I was attempting to simply redirect the page to the HTTPS version if it determined that HTTPS was off, but instead it's displaying an HTML page rather than actually redirecting; and even odder, it's displaying it as text/plain! The VirtualHost Declaration (Sort of): ServerAdmin [email protected] DocumentRoot "/path/to/files" ServerName example.com SSLEngine On SSLCertificateFile /etc/ssh/certify/example.com.crt SSLCertificateKeyFile /etc/ssh/certify/example.com.key SSLCertificateChainFile /etc/ssh/certify/sub.class1.server.ca.pem <Directory "/path/to/files/"> AllowOverride All Options +FollowSymLinks DirectoryIndex index.php Order allow,deny Allow from all </Directory> RewriteEngine On RewriteCond %{HTTPS} off RewriteRule .* https://example.com:6161 [R=301] The Page Output: <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>301 Moved Permanently</title> </head><body> <h1>Moved Permanently</h1> <p>The document has moved <a href="https://example.com:6161">here</a>.</p> <hr> <address>Apache/2.2.21 (Unix) mod_ssl/2.2.21 OpenSSL/1.0.0e DAV/2 Server at example.com Port 443</address> </body></html> I've tried moving the Rewrite stuff up above the SSL stuff hoping it'd do something and nothing happens. If I view the page with via HTTPS, it displays fine like it should. It's obviously detecting that I'm trying to rewrite the path, but it's not acting. The Apache error log does not indicate anything to me that might have gone wrong. When I remove the RewriteRules: <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>400 Bad Request</title> </head><body> <h1>Bad Request</h1> <p>Your browser sent a request that this server could not understand.<br /> Reason: You're speaking plain HTTP to an SSL-enabled server port.<br /> Instead use the HTTPS scheme to access this URL, please.<br /> <blockquote>Hint: <a href="https://example.com/"><b>https://example.com/</b></a></blockquote></p> <p>Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.</p> <hr> <address>Apache/2.2.21 (Unix) mod_ssl/2.2.21 OpenSSL/1.0.0e DAV/2 Server at example.com Port 443</address> </body></html> I get the standard "you can't do this because you're not using SSL" response, which is also provided in text/plain rather than being rendered as HTML. This would make sense, it should only work for HTTPS-enabled connections, but I still want to redirect them to the HTTPS connection when it determines that it is not enabled. Thinking I could circumvent the system: I tried adding a ErrorDocument 400 https://example.com:6161 to the config file instead of using RewriteRules, and that just gave me a new message, still no cheese. <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>302 Found</title> </head><body> <h1>Found</h1> <p>The document has moved <a href="https://example.com:6161">here</a>.</p> <hr> <address>Apache/2.2.21 (Unix) mod_ssl/2.2.21 OpenSSL/1.0.0e DAV/2 Server at example.com Port 443</address> </body></html> How can I force Apache to actually redirect rather than displaying a "301" page that shows HTML in plain-text format?

  • Issue in nginx proxying to apache

    - by Luis Masuelli
    My current nginx configuration is as follows: specific configuration for (currently two) domains: server { listen 443 ssl; server_name studiotv.service.tebusco.lan phpmyadmin.service.tebusco.lan; ssl_certificate /home/administrador/nginx-confs/ssl/service.tebusco.lan.crt; ssl_certificate_key /home/administrador/nginx-confs/ssl/service.tebusco.lan.key; location / { proxy_pass http://127.0.0.1:8180; proxy_set_header Host $http_host:8180; } } default configuration for unmatched ssl connections: server { listen 443 default ssl; ssl_certificate /home/administrador/nginx-confs/ssl/service.tebusco.lan.crt; ssl_certificate_key /home/administrador/nginx-confs/ssl/service.tebusco.lan.key; location / { return 403; } } http configuration: server { listen 80; rewrite ^ https://$host$request_uri? permanent; } The intention is clear: Redirect http traffic to https. Proxy each https:// call from phpmyadmin.service.tebusco.lan and studiotv.service.tebusco.lan to apache2. This includes passing a host header, which is detected. Each unmatched ssl connection must return a 403 in nginx. Does not even reach apache2. In the apache2 side of the life, I have a default site, and a non-default site which will match studiotv.service.tebusco.lan: 000-default.conf file (available and enabled): <VirtualHost 127.0.0.1:8180> # The ServerName directive sets the request scheme, hostname and port that # the server uses to identify itself. This is used when creating # redirection URLs. In the context of virtual hosts, the ServerName # specifies what hostname must appear in the request's Host: header to # match this virtual host. For the default virtual host (this file) this # value is not decisive as it is used as a last resort host regardless. # However, you must set it for any further virtual host explicitly.

Question: What am I missing? (apache 2.4.7, nginx 1.6.0, ubuntu server 14.04).

  • nginx + php-fpm - where are my $_GET params?

    - by egis
    I have a strange problem here. I just moved from apache + mod_php to nginx + php-fpm. Everything went fine except this one problem. I have a site, let's say example.com. When I access it like example.com?test=get_param $_SERVER['REQUEST_URI'] is /?test=get_param and there is a $_GET['test'] also. But when I access example.com/ajax/search/?search=get_param $_SERVER['REQUEST_URI'] is /ajax/search/?search=get_param yet there is no $_GET['search'] (there is no $_GET array at all). I'm using Kohana framework. which routes /ajax/search to controller, but I've put phpinfo() at index.php so I'm checking for $_GET variables before framework does anything (this means that disapearing get params aren't frameworks fault). My nginx.conf is like this worker_processes 4; pid logs/nginx.pid; events { worker_connections 1024; } http { index index.html index.php; autoindex on; autoindex_exact_size off; include mime.types; default_type application/octet-stream; server_names_hash_bucket_size 128; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log logs/access.log main; error_log logs/error.log debug; sendfile on; tcp_nopush on; tcp_nodelay off; keepalive_timeout 2; gzip on; gzip_comp_level 2; gzip_proxied any; gzip_types text/plain text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript; include sites-enabled/*; } and example.conf is like this server { listen 80; server_name www.example.com; rewrite ^ $scheme://example.com$request_uri? permanent; } server { listen 80; server_name example.com; root /var/www/example/; location ~ /\. { return 404; } location / { try_files $uri $uri/ /index.php; } location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include /usr/local/nginx/conf/fastcgi_params; } location ~* ^/(modules|application|system) { return 403; } # serve static files directly location ~* ^.+.(jpg|jpeg|gif|css|png|js|ico|html|xml|txt)$ { access_log off; expires 30d; } } fastcgi_params is like this 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 $server_protocol; fastcgi_param GATEWAY_INTERFACE CGI/1.1; fastcgi_param SERVER_SOFTWARE nginx/$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; fastcgi_connect_timeout 60; fastcgi_send_timeout 180; fastcgi_read_timeout 180; fastcgi_buffer_size 128k; fastcgi_buffers 4 256k; fastcgi_busy_buffers_size 256k; fastcgi_temp_file_write_size 256k; fastcgi_intercept_errors on; fastcgi_param QUERY_STRING $query_string; fastcgi_param PATH_INFO $fastcgi_path_info; What is the problem here?

My nginx.conf is like this worker_processes 4; pid logs/nginx.pid; events { worker_connections 1024; } http { index index.html index.php; autoindex on; autoindex_exact_size off; include mime.types; default_type application/octet-stream; server_names_hash_bucket_size 128; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log logs/access.log main; error_log logs/error.log debug; sendfile on; tcp_nopush on; tcp_nodelay off; keepalive_timeout 2; gzip on; gzip_comp_level 2; gzip_proxied any; gzip_types text/plain text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript; include sites-enabled/*; } and example.conf is like this server { listen 80; server_name www.example.com; rewrite ^ $scheme://example.com$request_uri? permanent; } server { listen 80; server_name example.com; root /var/www/example/; location ~ /\. { return 404; } location / { try_files $uri $uri/ /index.php; } location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include /usr/local/nginx/conf/fastcgi_params; } location ~* ^/(modules|application|system) { return 403; } # serve static files directly location ~* ^.+.(jpg|jpeg|gif|css|png|js|ico|html|xml|txt)$ { access_log off; expires 30d; } } fastcgi_params is like this 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 $server_protocol; fastcgi_param GATEWAY_INTERFACE CGI/1.1; fastcgi_param SERVER_SOFTWARE nginx/$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; fastcgi_connect_timeout 60; fastcgi_send_timeout 180; fastcgi_read_timeout 180; fastcgi_buffer_size 128k; fastcgi_buffers 4 256k; fastcgi_busy_buffers_size 256k; fastcgi_temp_file_write_size 256k; fastcgi_intercept_errors on; fastcgi_param QUERY_STRING $query_string; fastcgi_param PATH_INFO $fastcgi_path_info; What is the problem here? By the way there are few more sites on the same server, both Kohana based and plain php, that are working perfectly.

  • Unable to set nginx to serve my staging website

    - by user100778
    I'm having some troubles setting up nginx to serve my staging website. What I did is change the server_name but for some reasons it just doesn't work. The url scheme is "domain.foo" is production, "staging.domain.foo" is staging, "foobar.domain.foo" is a web service, "foobar.staging.domain.foo" is the staging version of the same webserver, ".domain.foo" is routed to serve some s3 static HTML, ".staging.domain.foo" is routed to serve some s3 static HTML in another bucket. All production urls work and are correctly configured, all staging urls doesn't work. Here is my conf file. You will see some duplication, I will gladly accept any correction/optimization, I'm a coder and configuring servers is definitely not my thing (but I'm eager to learn and improve...). server { listen 80; ## listen for ipv4 server_name "domain.foo" "www.domain.foo" default_server; access_log /var/log/nginx/access.log; client_max_body_size 5M; location / { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; location ~* \.(jpg|jpeg|gif|png|ico|css|bmp|js|html)$ { access_log off; expires max; root /home/foo/Foo/current/public; break; } if ($host ~ 'www.domain.foo') { rewrite ^/(.*)$ http://domain/foo/$1 permanent; } proxy_pass http://production; break; } } server { listen 80; server_name "staging.domain.foo"; access_log /var/log/nginx/access.staging.log; error_log /var/log/nginx/error.staging.log; client_max_body_size 5M; location / { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; proxy_pass http://staging; break; } } server { listen 80; ## listen for ipv4 server_name "foobar.domain.foo"; access_log /var/log/nginx/access.log; location / { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; if ($host = 'foobar.domain.foo') { proxy_pass http://foobar; break; } } } server { listen 80; ## listen for ipv4 server_name foobar.staging.domain.foo; location / { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; proxy_pass http://foobar_staging; break; } } server { listen 80; server_name "~^(.+)\.domain\.foo$"; location / { proxy_intercept_errors on; error_page 404 = http://domain.foo/404; set $subdomain $1; rewrite /$ "/$subdomain/index.html" break; rewrite ^ /$subdomain$request_uri? break; proxy_pass http://bucket.domain.foo.s3.amazonaws.com; } } server { listen 80; server_name "~^(.+)\.staging\.domain\.foo$"; location / { proxy_intercept_errors on; set $subdomain $1; rewrite /$ "/$subdomain/index.html" break; rewrite ^ /$subdomain$request_uri? break; proxy_pass http://bucket.staging.domain.foo.s3.amazonaws.com; } } upstream production { server 111.255.111.110:8000; server 111.255.111.110:8001; server 111.255.111.110:8002; server 111.255.111.110:8003; } upstream staging { server 222.255.222.222:8000; server 222.255.222.222:8001; } upstream foobar { server 111.255.222.165:9000; server 111.255.222.165:9001; server 111.255.222.165:9002; } upstream foobar_staging { server 222.255.222.222:9000; } What happens now when I point my browser to staging.domain.foo is that it hangs. Can't find anything in the logs, but for example the access.staging.log and errors.staging.log are created. Anybody has an idea? :)

  • Improving SAS multipath to JBOD performance on Linux

    - by user36825
    Hello all I'm trying to optimize a storage setup on some Sun hardware with Linux. Any thoughts would be greatly appreciated. We have the following hardware: Sun Blade X6270 2* LSISAS1068E SAS controllers 2* Sun J4400 JBODs with 1 TB disks (24 disks per JBOD) Fedora Core 12 2.6.33 release kernel from FC13 (also tried with latest 2.6.31 kernel from FC12, same results) Here's the datasheet for the SAS hardware: http://www.sun.com/storage/storage_networking/hba/sas/PCIe.pdf It's using PCI Express 1.0a, 8x lanes. With a bandwidth of 250 MB/sec per lane, we should be able to do 2000 MB/sec per SAS controller. Each controller can do 3 Gb/sec per port and has two 4 port PHYs. We connect both PHYs from a controller to a JBOD. So between the JBOD and the controller we have 2 PHYs * 4 SAS ports * 3 Gb/sec = 24 Gb/sec of bandwidth, which is more than the PCI Express bandwidth. With write caching enabled and when doing big writes, each disk can sustain about 80 MB/sec (near the start of the disk). With 24 disks, that means we should be able to do 1920 MB/sec per JBOD. multipath { rr_min_io 100 uid 0 path_grouping_policy multibus failback manual path_selector "round-robin 0" rr_weight priorities alias somealias no_path_retry queue mode 0644 gid 0 wwid somewwid } I tried values of 50, 100, 1000 for rr_min_io, but it doesn't seem to make much difference. Along with varying rr_min_io I tried adding some delay between starting the dd's to prevent all of them writing over the same PHY at the same time, but this didn't make any difference, so I think the I/O's are getting properly spread out. According to /proc/interrupts, the SAS controllers are using a "IR-IO-APIC-fasteoi" interrupt scheme. For some reason only core #0 in the machine is handling these interrupts. I can improve performance slightly by assigning a separate core to handle the interrupts for each SAS controller: echo 2 /proc/irq/24/smp_affinity echo 4 /proc/irq/26/smp_affinity Using dd to write to the disk generates "Function call interrupts" (no idea what these are), which are handled by core #4, so I keep other processes off this core too. I run 48 dd's (one for each disk), assigning them to cores not dealing with interrupts like so: taskset -c somecore dd if=/dev/zero of=/dev/mapper/mpathx oflag=direct bs=128M oflag=direct prevents any kind of buffer cache from getting involved. None of my cores seem maxed out. The cores dealing with interrupts are mostly idle and all the other cores are waiting on I/O as one would expect.

  • Modifying a gedit syntax highlighting file

    - by Oscar Saleta Reig
    I am trying to change a highlighting file from Gedit. I have modified the file /usr/share/gtksourceview-3.0/language-specs/fortran.lang because I want to change the cases in which the editor takes a statement as a comment. The problem I have is that when I choose the new highlighting scheme nothing highlights, it just remains as plain text. The file fortran.lang was opened with su permissions and I just copy-pasted everything into a new Gedit file and later saved it as fortran_enhanced.lang in the same folder. The changes I've done to the original file are these: Original fortran.lang file: <language id="fortran" _name="Fortran 95" version="2.0" _section="Sources"> <metadata> <property name="mimetypes">text/x-fortran</property> <property name="globs">*.f;*.f90;*.f95;*.for</property> <property name="line-comment-start">!</property> </metadata> <styles> <style id="comment" _name="Comment" map-to="def:comment"/> <style id="floating-point" _name="Floating Point" map-to="def:floating-point"/> <style id="keyword" _name="Keyword" map-to="def:keyword"/> <style id="intrinsic" _name="Intrinsic function" map-to="def:builtin"/> <style id="boz-literal" _name="BOZ Literal" map-to="def:base-n-integer"/> <style id="decimal" _name="Decimal" map-to="def:decimal"/> <style id="type" _name="Data Type" map-to="def:type"/> </styles> <default-regex-options case-sensitive="false"/> <definitions> <!-- Note: contains an hack to avoid considering ^COMMON a comment --> <context id="line-comment" style-ref="comment" end-at-line-end="true" class="comment" class-disabled="no-spell-check"> <start>!|(^[Cc](\b|[^OoAaYy]))</start> <include> <context ref="def:escape"/> <context ref="def:in-line-comment"/> </include> </context> (...) Modified fortran_enhanced.lang file: <!-- Note: changed language id and name --> <language id="fortran_enhanced" _name="Fortran 95 2.0" version="2.0" _section="Sources"> <metadata> <property name="mimetypes">text/x-fortran</property> <!-- Note: removed *.f and *.for from file extensions --> <property name="globs">*.f90;*.f95;</property> <property name="line-comment-start">!</property> </metadata> <styles> <style id="comment" _name="Comment" map-to="def:comment"/> <style id="floating-point" _name="Floating Point" map-to="def:floating-point"/> <style id="keyword" _name="Keyword" map-to="def:keyword"/> <style id="intrinsic" _name="Intrinsic function" map-to="def:builtin"/> <style id="boz-literal" _name="BOZ Literal" map-to="def:base-n-integer"/> <style id="decimal" _name="Decimal" map-to="def:decimal"/> <style id="type" _name="Data Type" map-to="def:type"/> </styles> <default-regex-options case-sensitive="false"/> <definitions> <!-- Note: I want comments only beginning with !, not C --> <context id="line-comment" style-ref="comment" end-at-line-end="true" class="comment" class-disabled="no-spell-check"> <start>!</start> <include> <context ref="def:escape"/> <context ref="def:in-line-comment"/> </include> </context> (...) I have read this question [ Custom gedit Syntax Highlighting for Dummies? ] and I tried to make the new fortran_enhanced.lang file readable with $ cd /usr/share/gtksourceview-3.0/language-specs $ sudo chmod 0644 fortran_enhanced.lang but it doesn't seem that made some difference. I have to say that I have never done a thing like this before and I don't even understand most of the language file, so I am open to every criticism, as I have been guided purely by intuition. Thank you in advanced!

  • How to invalidate nginx reverse proxy cache in front of other nginx servers?

    - by Olivier Lance
    I'm running a Proxmox server on a single IP address, that will dispatch HTTP requests to containers depending on the requested host. I am using nginx on the Proxmox side to listen to HTTP requests and I am using the proxy_pass directive in my different server blocks to dispatch requests according to the server_name. My containers run on Ubuntu and are also running a nginx instance. I'm having troubles with caching on a particular website that is fully static: nginx keeps on serving me stale content after files updates, until I: Clear /var/cache/nginx/ and restart nginx or set proxy_cache off for this server and reload the config Here's the detail of my configuration: On the server (proxmox): /etc/nginx/nginx.conf: user www-data; worker_processes 8; pid /var/run/nginx.pid; events { worker_connections 768; # multi_accept on; use epoll; } http { ## # Basic Settings ## sendfile on; #tcp_nopush on; tcp_nodelay on; #keepalive_timeout 65; types_hash_max_size 2048; server_tokens off; # server_names_hash_bucket_size 64; # server_name_in_redirect off; include /etc/nginx/mime.types; default_type application/octet-stream; client_body_buffer_size 1k; client_max_body_size 8m; large_client_header_buffers 1 1K; ignore_invalid_headers on; client_body_timeout 5; client_header_timeout 5; keepalive_timeout 5 5; send_timeout 5; server_name_in_redirect off; ## # Logging Settings ## access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; ## # Gzip Settings ## gzip on; gzip_disable "MSIE [1-6]\.(?!.*SV1)"; gzip_vary on; gzip_proxied any; gzip_comp_level 6; # gzip_buffers 16 8k; gzip_http_version 1.1; gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript; limit_conn_zone $binary_remote_addr zone=gulag:1m; limit_conn gulag 50; ## # Virtual Host Configs ## include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; } /etc/nginx/conf.d/proxy.conf: proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_hide_header X-Powered-By; proxy_intercept_errors on; proxy_buffering on; proxy_cache_key "$scheme://$host$request_uri"; proxy_cache_path /var/cache/nginx levels=1:2 keys_zone=cache:10m inactive=7d max_size=700m; /etc/nginx/sites-available/my-domain.conf: server { listen 80; server_name .my-domain.com; access_log off; location / { proxy_pass http://my-domain.local:80/; proxy_cache cache; proxy_cache_valid 12h; expires 30d; proxy_cache_use_stale error timeout invalid_header updating; } } On the container (my-domain.local): nginx.conf: (everything is inside the main config file -- it's been done quickly...) user www-data; worker_processes 1; error_log logs/error.log; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; #tcp_nopush on; keepalive_timeout 65; gzip off; server { listen 80; server_name .my-domain.com; root /var/www; access_log logs/host.access.log; } } I've read many blog posts and answers before resolving to posting my own questions... most answers I can see suggest setting sendfile off; but that didn't work for me. I have tried many other things, double checked my settings and all seems fine. So I'm wondering whether I am not expecting nginx's cache to do something it's not meant to...? Basically, I thought that if one of my static files in my container was updated, the cache in my reverse proxy would be invalidated and my browser would get the new version of the file when it requests it... But I now have the sentiment I misunderstood many things. Of all things, I now wonder how nginx on the server can know about a file in the container has changed? I have seen a directive proxy_header_pass (or something alike), should I use this to let the nginx instance from the container somehow inform the one in Proxmox about updated files? Is this expectation just a dream, or can I do it with nginx on my current architecture?

  • How to decrypt an encrypted Apple iTunes iPhone backup?

    - by afit
    I've been asked by a number of unfortunate iPhone users to help them restore data from their iTunes backups. This is easy when they are unencrypted, but not when they are encrypted, whether or not the password is known. As such, I'm trying to figure out the encryption scheme used on mddata and mdinfo files when encrypted. I have no problems reading these files otherwise, and have built some robust C# libraries for doing so. (If you're able to help, I don't care which language you use. It's the principle I'm after here!) The Apple "iPhone OS Enterprise Deployment Guide" states that "Device backups can be stored in encrypted format by selecting the Encrypt iPhone Backup option in the device summary pane of iTunes. Files are encrypted using AES128 with a 256-bit key. The key is stored securely in the iPhone keychain." That's a pretty good clue, and there's some good info here on Stackoverflow on iPhone AES/Rijndael interoperability suggesting a keysize of 128 and CBC mode may be used. Aside from any other obfuscation, a key and initialisation vector (IV)/salt are required. One might assume that the key is a manipulation of the "backup password" that users are prompted to enter by iTunes and passed to "AppleMobileBackup.exe", padded in a fashion dictated by CBC. However, given the reference to the iPhone keychain, I wonder whether the "backup password" might not be used as a password on an X509 certificate or symmetric private key, and that the certificate or private key itself might be used as the key. (AES and the iTunes encrypt/decrypt process is symmetric.) The IV is another matter, and it could be a few things. Perhaps it's one of the keys hard-coded into iTunes, or into the devices themselves. Although Apple's comment above suggests the key is present on the device's keychain, I think this isn't that important. One can restore an encrypted backup to a different device, which suggests all information relevant to the decryption is present in the backup and iTunes configuration, and that anything solely on the device is irrelevant and replacable in this context. So where might be the key be? I've listed paths below from a Windows machine but it's much of a muchness whichever OS we use. The "\appdata\Roaming\Apple Computer\iTunes\itunesprefs.xml" contains a PList with a "Keychain" dict entry in it. The "\programdata\apple\Lockdown\09037027da8f4bdefdea97d706703ca034c88bab.plist" contains a PList with "DeviceCertificate", "HostCertificate", and "RootCertificate", all of which appear to be valid X509 certs. The same file also appears to contain asymmetric keys "RootPrivateKey" and "HostPrivateKey" (my reading suggests these might be PKCS #7-enveloped). Also, within each backup there are "AuthSignature" and "AuthData" values in the Manifest.plist file, although these appear to be rotated as each file gets incrementally backed up, suggested they're not that useful as a key, unless something really quite involved is being done. There's a lot of misleading stuff out there suggesting getting data from encrypted backups is easy. It's not, and to my knowledge it hasn't been done. Bypassing or disabling the backup encryption is another matter entirely, and is not what I'm looking to do. This isn't about hacking apart the iPhone or anything like that. All I'm after here is a means to extract data (photos, contacts, etc.) from encrypted iTunes backups as I can unencrypted ones. I've tried all sorts of permutations with the information I've put down above but got nowhere. I'd appreciate any thoughts or techniques I might have missed.

  • Parallelism in .NET – Part 11, Divide and Conquer via Parallel.Invoke

    - by Reed
    Many algorithms are easily written to work via recursion.  For example, most data-oriented tasks where a tree of data must be processed are much more easily handled by starting at the root, and recursively “walking” the tree.  Some algorithms work this way on flat data structures, such as arrays, as well.  This is a form of divide and conquer: an algorithm design which is based around breaking up a set of work recursively, “dividing” the total work in each recursive step, and “conquering” the work when the remaining work is small enough to be solved easily. Recursive algorithms, especially ones based on a form of divide and conquer, are often a very good candidate for parallelization. This is apparent from a common sense standpoint.  Since we’re dividing up the total work in the algorithm, we have an obvious, built-in partitioning scheme.  Once partitioned, the data can be worked upon independently, so there is good, clean isolation of data. Implementing this type of algorithm is fairly simple.  The Parallel class in .NET 4 includes a method suited for this type of operation: Parallel.Invoke.  This method works by taking any number of delegates defined as an Action, and operating them all in parallel.  The method returns when every delegate has completed: Parallel.Invoke( () => { Console.WriteLine("Action 1 executing in thread {0}", Thread.CurrentThread.ManagedThreadId); }, () => { Console.WriteLine("Action 2 executing in thread {0}", Thread.CurrentThread.ManagedThreadId); }, () => { Console.WriteLine("Action 3 executing in thread {0}", Thread.CurrentThread.ManagedThreadId); } ); .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Running this simple example demonstrates the ease of using this method.  For example, on my system, I get three separate thread IDs when running the above code.  By allowing any number of delegates to be executed directly, concurrently, the Parallel.Invoke method provides us an easy way to parallelize any algorithm based on divide and conquer.  We can divide our work in each step, and execute each task in parallel, recursively. For example, suppose we wanted to implement our own quicksort routine.  The quicksort algorithm can be designed based on divide and conquer.  In each iteration, we pick a pivot point, and use that to partition the total array.  We swap the elements around the pivot, then recursively sort the lists on each side of the pivot.  For example, let’s look at this simple, sequential implementation of quicksort: public static void QuickSort<T>(T[] array) where T : IComparable<T> { QuickSortInternal(array, 0, array.Length - 1); } private static void QuickSortInternal<T>(T[] array, int left, int right) where T : IComparable<T> { if (left >= right) { return; } SwapElements(array, left, (left + right) / 2); int last = left; for (int current = left + 1; current <= right; ++current) { if (array[current].CompareTo(array[left]) < 0) { ++last; SwapElements(array, last, current); } } SwapElements(array, left, last); QuickSortInternal(array, left, last - 1); QuickSortInternal(array, last + 1, right); } static void SwapElements<T>(T[] array, int i, int j) { T temp = array[i]; array[i] = array[j]; array[j] = temp; } Here, we implement the quicksort algorithm in a very common, divide and conquer approach.  Running this against the built-in Array.Sort routine shows that we get the exact same answers (although the framework’s sort routine is slightly faster).  On my system, for example, I can use framework’s sort to sort ten million random doubles in about 7.3s, and this implementation takes about 9.3s on average. Looking at this routine, though, there is a clear opportunity to parallelize.  At the end of QuickSortInternal, we recursively call into QuickSortInternal with each partition of the array after the pivot is chosen.  This can be rewritten to use Parallel.Invoke by simply changing it to: // Code above is unchanged... SwapElements(array, left, last); Parallel.Invoke( () => QuickSortInternal(array, left, last - 1), () => QuickSortInternal(array, last + 1, right) ); } This routine will now run in parallel.  When executing, we now see the CPU usage across all cores spike while it executes.  However, there is a significant problem here – by parallelizing this routine, we took it from an execution time of 9.3s to an execution time of approximately 14 seconds!  We’re using more resources as seen in the CPU usage, but the overall result is a dramatic slowdown in overall processing time. This occurs because parallelization adds overhead.  Each time we split this array, we spawn two new tasks to parallelize this algorithm!  This is far, far too many tasks for our cores to operate upon at a single time.  In effect, we’re “over-parallelizing” this routine.  This is a common problem when working with divide and conquer algorithms, and leads to an important observation: When parallelizing a recursive routine, take special care not to add more tasks than necessary to fully utilize your system. This can be done with a few different approaches, in this case.  Typically, the way to handle this is to stop parallelizing the routine at a certain point, and revert back to the serial approach.  Since the first few recursions will all still be parallelized, our “deeper” recursive tasks will be running in parallel, and can take full advantage of the machine.  This also dramatically reduces the overhead added by parallelizing, since we’re only adding overhead for the first few recursive calls.  There are two basic approaches we can take here.  The first approach would be to look at the total work size, and if it’s smaller than a specific threshold, revert to our serial implementation.  In this case, we could just check right-left, and if it’s under a threshold, call the methods directly instead of using Parallel.Invoke. The second approach is to track how “deep” in the “tree” we are currently at, and if we are below some number of levels, stop parallelizing.  This approach is a more general-purpose approach, since it works on routines which parse trees as well as routines working off of a single array, but may not work as well if a poor partitioning strategy is chosen or the tree is not balanced evenly. This can be written very easily.  If we pass a maxDepth parameter into our internal routine, we can restrict the amount of times we parallelize by changing the recursive call to: // Code above is unchanged... SwapElements(array, left, last); if (maxDepth < 1) { QuickSortInternal(array, left, last - 1, maxDepth); QuickSortInternal(array, last + 1, right, maxDepth); } else { --maxDepth; Parallel.Invoke( () => QuickSortInternal(array, left, last - 1, maxDepth), () => QuickSortInternal(array, last + 1, right, maxDepth)); } We no longer allow this to parallelize indefinitely – only to a specific depth, at which time we revert to a serial implementation.  By starting the routine with a maxDepth equal to Environment.ProcessorCount, we can restrict the total amount of parallel operations significantly, but still provide adequate work for each processing core. With this final change, my timings are much better.  On average, I get the following timings: Framework via Array.Sort: 7.3 seconds Serial Quicksort Implementation: 9.3 seconds Naive Parallel Implementation: 14 seconds Parallel Implementation Restricting Depth: 4.7 seconds Finally, we are now faster than the framework’s Array.Sort implementation.

  • HOWTO: disable jmx in activemq network of brokers (spring, xbean)

    - by subes
    Since I've struggled a lot with this problem, I am posting my solution. Disabling jmx in an activemq network of brokers removes race conditions about the registration of the jmx connector. When starting multiple activemq servers on the same machine: Failed to start jmx connector: Cannot bind to URL [rmi://localhost:1099/jmxrmi]: javax.naming.NameAlreadyBoundException: jmxrmi [Root exception is java.rmi.AlreadyBoundException: jmxrmi] Another problem with this is, that even if you don't cause a race condition, this exception can still occur. Even when starting one broker after another while waiting for them to initialize properly in between. If one process is run by root as the first instance and the other as a normal user, somehow the user process tries to register its own jmx connector, though there already is one. Or another exception which happens when the broker that successfully registered the jmx connector goes down: Failed to start jmx connector: Cannot bind to URL [rmi://localhost:1099/jmxrmi]: javax.naming.ServiceUnavailableException [Root exception is java.rmi.ConnectException: Connection refused to host: localhost; nested exception is: java.net.ConnectException: Connection refused] Those exceptions cause the network of brokers to stop working, or to not work at all. The trick to disable jmx was, that jmx had to be disabled in the connectionfactory aswell. The documentation http://activemq.apache.org/jmx.html does not say that this is needed explicitly. So I had to struggle for 2 days until I found the solution: <beans xmlns="http://www.springframework.org/schema/beans" xmlns:amq="http://activemq.apache.org/schema/core" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://activemq.apache.org/schema/core http://activemq.apache.org/schema/core/activemq-core-5.3.1.xsd"> <!-- Spring JMS Template --> <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate"> <constructor-arg ref="connectionFactory" /> </bean> <!-- Caching, sodass das jms template überhaupt nutzbar ist in sachen performance --> <bean id="connectionFactory" class="org.springframework.jms.connection.CachingConnectionFactory"> <constructor-arg ref="amqConnectionFactory" /> <property name="exceptionListener" ref="jmsExceptionListener" /> <property name="sessionCacheSize" value="1" /> </bean> <!-- Jeder Client verbindet sich mit seinem eigenen broker, broker sind untereinander vernetzt. Nur wenn hier nochmals jmx deaktiviert wird, bleibt es auch deaktiviert... --> <amq:connectionFactory id="amqConnectionFactory" brokerURL="vm://broker:default?useJmx=false" /> <!-- Broker suchen sich einen eigenen Port und sind gegenseitig verbunden, ergeben dadurch ein Grid. Dies zwar etwas langsamer, aber dafür ausfallsicherer. Siehe http://activemq.apache.org/networks-of-brokers.html --> <amq:broker useJmx="false" persistent="false"> <!-- Wird benötigt um JMX endgültig zu deaktivieren --> <amq:managementContext> <amq:managementContext connectorHost="localhost" createConnector="false" /> </amq:managementContext> <!-- Nun die normale Konfiguration für Network of Brokers --> <amq:networkConnectors> <amq:networkConnector networkTTL="1" duplex="true" dynamicOnly="true" uri="multicast://default" /> </amq:networkConnectors> <amq:persistenceAdapter> <amq:memoryPersistenceAdapter /> </amq:persistenceAdapter> <amq:transportConnectors> <amq:transportConnector uri="tcp://localhost:0" discoveryUri="multicast://default" /> </amq:transportConnectors> </amq:broker> With this, there is no need to specify -Dcom.sun.management.jmxremote=false for the jvm. Which somehow also didn't work for me, because the connectionfactory started the jmx connector.

  • Do’s and Don’ts Building SharePoint Applications

    - by Bil Simser
    SharePoint is a great platform for building quick LOB applications. Simple things from employee time trackers to server and software inventory to full blown Help Desks can be crafted up using SharePoint from just customizing Lists. No programming necessary. However there are a few tricks I’ve painfully learned over the years that you can use for your own solutions. DO What’s In A Name? When you create a new list, column, or view you’ll commonly name it something like “Expense Reports”. However this has the ugly effect of creating a url to the list as “Expense%20Reports”. Or worse, an internal field name of “Expense_x0x0020_Reports” which is not only cryptic but hard to remember when you’re trying to find the column by internal name. While “Expense Reports 2011” is user friendly, “ExpenseReports2011” is not (unless you’re a programmer). So that’s not the solution. Well, not entirely. Instead when you create your column or list or view use the scrunched up name (I can’t think of the technical term for it right now) of “ExpenseReports2011”, “WomenAtTheOfficeThatAreMen” or “KoalaMeatIsGoodWhenBroiled”. After you’ve created it, go back and change the name to the more friendly “Silly Expense Reports That Nobody Reads”. The original internal name will be the url and code friendly one without spaces while the one used on data entry forms and view headers will be the human version. Smart Columns When building a view include columns that make sense. By default when you add a column the “Add to default view” is checked. Resist the urge to be lazy and leave it checked. Uncheck that puppy and decide consciously what columns should be included in the view. Pick columns that make sense to what the user is trying to do. This means you have to talk to the user. Yes, I know. That can be trying at times and even painful. Go ahead, talk to them. You might learn something. Find out what’s important to them and why. If they’re doing something repetitively as part of their job, try to make their life easier by including what’s most important to them. Do they really need to see the Created *and* Modified date of a document or do they just need the title and author? You’ll only find out after talking to them (or getting them drunk in a bar and leaving them in the back alley handcuffed to a garbage bin, don’t ask). Gotta Keep it Separated Hey, views are there for a reason. Use them. While “All Items” is a fine way to present a list of well, all items, it’s hardly sufficient to present a list of servers built before the Y2K bug hit. You’ll be scrolling the list for hours finally arriving at Page 387 of 12,591 and cursing that SharePoint guy for convincing you that putting your hardware into a list would be of any use to anyone. Next to collecting the data, presenting it is just as important. Views are often overlooked and many times ignored or misused. They’re the way you can slice and dice the data up so that you’re not trying to consume 3,000 years of human evolution on a single web page. Remember views can be filtered so feel free to create a view for each status or one for each operating system or one for each species of Information Worker you might be putting in that list or document library. Not only will it reduce the number of items someone sees at one time, it’ll also make the information that much more relevant. Also remember that each view is a separate page. Use it in navigation by creating a menu on the Quick Launch to each view. The discoverability of the Views menu isn’t overly obvious and if you violate the rule of columns (see Horizontally Scrolling below) the view menu doesn’t even show up until you shuffle the scroll bar to the left. Navigation links, big giant buttons, a screaming flashing “CLICK ME NOW” will help your users find their way. Sort It! Views are great so we’re building nice, rich views for the user. Awesomesauce. However sort is not very discoverable by the user. For example when you’re looking at a view how do you know if it’s ascending or descending and what is it sorted on. Maybe it’s sorted using two fields so what’s that all about? Help your users by letting them know the information they’re looking at is sorted. Maybe you name the view something appropriate like “Bogus Expense Claims Sorted By Deadbeats”. If you use the naming strategy just make sure you keep the name consistent with the description. In the previous example their better be a Deadbeat column so I can see the sort in action. Having a “Loser” column, while equally correct, is a little obtuse to the average Information Worker. Remember, they usually don’t use acronyms and even if they knew how to, it’s not immediately obvious to them that’s what you’re trying to convey. Another option is to simply drop a Content Editor Web Part above the list and explain exactly the view they’re looking at. Each view is it’s own page so one CEWP won’t be used across the board. Be descriptive in what the user is seeing but try to keep it brief. Dumping the first chapter of I, Claudius might be informative to the data but can gobble up screen real estate and miss the point of having the list. DO NOT Useless Attachments The attachments column is, in a word, useless. For the most part. Sure it indicates there’s an attachment on the list item but in the grand scheme of things that’s not overly informative. Maybe it is and by all means, if it makes sense to you include it. Colour it. Make it shine and stand like the Return of Clippy on every SharePoint list. Without it being functional it can be boring. EndUserSharePoint.com has an article to make the son of Clippy that much more useful so feel free to head over and check out this blog post by Paul Grenier on the task (Warning code ahead! Danger Will Robinson!) In any case, I would suggest you remove it from your views. Again if it’s important then include it but consider the jQuery solution above to make it functional. It’s added by default to views and one of things that people forget to clean up. Horizontal Scrolling Screen real estate is premium so building a list that contains 8,000 columns and stretches horizontally across 15 screens probably isn’t the most user friendly experience. Most users can’t figure out how to scroll vertically let alone horizontally so don’t make it even that more confusing for them. Take the Steve Krug approach in your view designs and try not to make the user think. Again views are your friend. Consider splitting up the data into views where one view contains 10 columns and other view contains the other 10. Okay, maybe your information doesn’t work that way but humans can only process 7 pieces of data at a time, 10 at most (then their heads explode and you don’t want to clean that mess up, especially on a Friday night before the big dance). It drives me batshit crazy when I see a view with 80 columns of data. I often ask the user “So what do you do with all this information”. The response is usually “With this data [the first 10 columns] I decide if I’m going to fire everyone, and with this data [the next 10 columns] I decide if I’m going to set the building on fire and collect the insurance”. It’s at that point I show them how to create two new views “People Who Are About To Get The Axe” and “Beach Time For The Executives”. Again, talk to your users and try to reason with them on cutting down the number of columns they see at once. Vertical Scrolling Another big faux pas I find is the use of multi-line comment fields in views. It’s not so bad when you have a statement like this in your view: “I really like, oh my god, thought I was going to scream when I saw this turtle then I decided what I was going to have for dinner and frankly I hate having to work late so when I was talking to the customer I thought, oh my god, what if the customer has turtles and then it appeared to me that I really was hungry so I'm going to have lunch now.” It’s fine if that’s the only column along with two or three others, but once you slap those 20 columns of data into the list, the comment field wraps and forms a new multi-page novel that takes up your entire screen. Do everyone a favour and just avoid adding the column to views. Train the user to just click through to the item if they need to see the contents. Duplicate Information Duplication is never good. Views and great as you can group data together. For example create a view of project status reports grouped by author. Then you can see what project manager is being a dip and not submitting their report. However if you group by author do you really need the Created By field as well in the view? Or if the view is grouped by Project then Author do you need both. Horizontal real estate is always at a premium so try not to clutter up the view with duplicate data like this. Oh  yeah, if you’re scratching your head saying “But Bil, if I don’t include the Project name in the view and I have a lot of items then how do I know which one I’m looking at”. That’s a hint that your grouping is too vague or you have too much data in the view based on that criteria. Filter it down a notch, create some views, and try to keep the group down to a single screen where you can see the group header at the top of the page. Again it’s just managing the information you have. Redundant, See Redundant This partially relates to duplicate information and smart columns but basically remember to not include the obvious in a view. Remember, don’t make me think. If you’ve gone to the trouble (and it was a lot of trouble wasn’t it?) to create separate views of your data by creating a “September Zombie Brain Sales”, “October Zombie Brain Sales”, etc. then please for the love of all that is holy do not include the Month and Product columns in your view. Similarly if you create a “My” view of anything (“My Favourite Brands of Spandex”, “My Co-Workers I Find The Urge To Disinfect”) then again, do not include the owner or author field (or whatever field you use to identify “My”). That’s just silly. Hope that helps! Happy customizing!

  • Using Oracle Enterprise Manager Ops Center to Update Solaris via Live Upgrade

    - by LeonShaner
    Introduction: This Oracle Enterprise Manager Ops Center blog entry provides tips for using Ops Center to update Solaris using Live Upgrade on Solaris 10 and Boot Environments on Solaris 11. Why use Live Upgrade? Live Upgrade (LU) can significantly reduce downtime associated with patching Live Upgrade avoids dropping to single-user mode for long periods of time during patching Live Upgrade relies on an Alternate Boot Environment (ABE)/(BE), which is patched while in multi-user mode; thereby allowing normal system operations to continue with the active BE, while the alternate BE is being patched Activating an newly patched (A)BE is essentially a reboot; therefore the downtime is ~= reboot Admins can easily revert to the prior Boot Environment (BE) as a safeguard / fallback. Why use Ops Center to patch via Live Upgrade, Alternate Boot Environments, and Solaris 11 equivalents? All the benefits of Ops Center's extensive patch and package knowledge base can be leveraged on top of Live Upgrade Ops Center can orchestrate patching based on Live Upgrade and Solaris 11 features, which all works together to minimize downtime Ops Centers advanced inventory and reporting features assurance that each OS is updated to a verifiable, consistent standard, rather than relying on ad-hoc (error prone) procedures and scripts Ops Center gives admins control over the boot environment specifications or they can let Ops Center decide when a BE is necessary, thereby reducing complexity and lowering the opportunity for user error Preparing to use Live Upgrade-like features in Solaris 11 Requirements and information you should know: Global Zone Root file-systems must be separate from Solaris Container / Zone filesystems Solaris 11 has features which are similar in concept to Live Upgrade on Solaris 10, but differ greatly in implementationImportant distinctions: Solaris 11 assumes ZFS root Solaris 11 adds Boot Environments (BE's) as an integrated feature (see beadm) Solaris 11 BE's avoid single-user patching (vs. Solaris 10 w/ ZFS snapshot=ABE). Solaris 11 Image Packaging System (IPS) has hooks for BE creation, as needed Solaris 11 allows pkgs to be installed + upgraded in alternate BE (e.g. instead of the live system) but it is controlled on a per-pkg basis Boot Environments are activated across a reboot; instead of spending long periods installing + upgrading packages in single user mode. Fallback to a prior BE is a function of the BE infrastructure (a la beadm). (Generally) Reboot + BE activation can be much much faster on Solaris 11 Preparing to use Live Upgrade on Solaris 10 Requirements and information you should know: Global Zone Root file-systems must be separate from Solaris Container / Zone filesystems Live Upgrade Pre-requisite patches must be applied before the first Live Upgrade Alternate Boot Environments are created (see "Pre-requisite Patches" section, below...) Solaris 10 Update 6 or newer on ZFS root is the practical starting point for Live Upgrade Live Upgrade with ZFS root is far more straight-forward than any scheme based on Alternative Boot Environments in slices or temporarily breaking mirrors Use Solaris best practices to upgrade the OS to at least Solaris 10 Update 4 (outside of Ops Center) UFS root can (technically) be used, but it is significantly more involved (e.g. discouraged) -- there are many reasons to move to ZFS while going through the process to update to Solaris 10 Update 6 or newer (out side of Ops Center) Recommendation: Start with Solaris 10 Update 6 or newer on ZFS root Recommendation: Start with Ops Center 12c or newer Ops Center 12c can automatically create your ABE's for you, without the need for custom scripts Ops Center 12c Update 2 avoids kernel panic on unpatched Solaris 10 update 9 (and older) -- unrelated to Live Upgrade, but more on the issue, below. NOTE: There is no magic!  If you have systems running Solaris 10 Update 5 or older on UFS root, and you don't know how to get them updated to Solaris 10 on ZFS root, then there are services available from Oracle Advanced Customer Support (ACS), which specialize in this area. Live Upgrade Pre-requisite Patches (Solaris 10) Certain Live Upgrade related patches must be present before the first Live Upgrade ABE's are created on Solaris 10.Use the following MOS Search String to find the “living document” that outlines the required patch minimums, which are necessary before using any Live Upgrade features: Solaris Live Upgrade Software Patch Requirements(Click above – the link is valid as of this writing, but search in MOS for the same "Solaris Live Upgrade Software Patch Requirements" string if necessary) It is a very good idea to check the document periodically and adapt to its contents, accordingly.IMPORTANT:  In case it wasn't clear in the above document, some direct patching of the active OS, including a reboot, may be required before Live Upgrade can be successfully used the first time.HINT: You can use Ops Center to determine what to expect for a given system, and to schedule the “pre-patching” during a maintenance window if necessary. Preparing to use Ops Center Discover + Manage (Install + Configure the Ops Center agent in) each Global Zone Recommendation:  Begin by using OCDoctor --agent-prereq to determine whether OS meets OC prerequisites (resolve any issues) See prior requirements and recommendations w.r.t. starting with Solaris 10 Update 6 or newer on ZFS (or at least Solaris 10 Update 4 on UFS, with caveats) WARNING: Systems running unpatched Solaris 10 update 9 (or older) should run the Ops Center 12c Update 2 agent to avoid a potential kernel panic The 12c Update 2 agent will check patch minimums and disable certain process accounting features if the kernel is not sufficiently patched to avoid the panic SPARC: 142900-05 Obsoleted by: 142900-06 SunOS 5.10: kernel patch 10 Oracle Solaris on SPARC (32-bit) X64: 142901-05 Obsoleted by: 142901-06 SunOS 5.10_x86: kernel patch 10 Oracle Solaris on x86 (32-bit) OR SPARC: 142909-17 SunOS 5.10: kernel patch 10 Oracle Solaris on SPARC (32-bit) X64: 142910-17 SunOS 5.10_x86: kernel patch 10 Oracle Solaris on x86 (32-bit) Ops Center 12c (initial release) and 12c Update 1 agent can also be safely used with a workaround (to be performed BEFORE installing the agent): # mkdir -p /etc/opt/sun/oc # echo "zstat_exacct_allowed=false" > /etc/opt/sun/oc/zstat.conf # chmod 755 /etc/opt/sun /etc/opt/sun/oc # chmod 644 /etc/opt/sun/oc/zstat.conf # chown -Rh root:sys /etc/opt/sun/oc NOTE: Remove the above after patching the OS sufficiently, or after upgrading to the 12c Update 2 agent Using Ops Center to apply Live Upgrade-related Pre-Patches (Solaris 10)Overview: Create an OS Update Profile containing the minimum LU-related pre-patches, based on the Solaris Live Upgrade Software Patch Requirements, previously mentioned. SIMULATE the deployment of the LU-related pre-patches Observe whether any of the LU-related pre-patches will require a reboot The job details for each Global Zone will advise whether a reboot step will be required ACTUALLY deploy the LU-related pre-patches, according to your change control process (e.g. if no reboot, maybe okay to do now; vs. must do later because of the reboot). You can schedule the job to occur later, during a maintenance window Check the job status for each node, resolving any issues found Once the LU-related pre-patches are applied, you can Ops Center to patch using Live Upgrade on Solaris 10 Using Ops Center to patch Solaris 10 with LU/ABE's -- the GOODS!(this is the heart of the tip): Create an OS Update Profile containing the patches that make up your standard build Use Solaris Baselines when possible Add other individual patches as needed ACTUALLY deploy the OS Update Profile Specify the appropriate Live Upgrade options, e.g. Synchronize the active BE to the alternate BE before patching Do not activate the BE after patching Check the job status for each node, resolving any issues found Activate the newly patched BE according to your change control process Activate = Reboot to the ABE, making the ABE the new active BE Ops Center does not separate LU activate from reboot, so expect a reboot! Check the job status for each node, resolving any issues found Examples (w/Screenshots) Solaris 10 and Live Upgrade: Auto-Create the Alternate Boot Environment (ZFS root only) ABE to be created on ZFS with name S10_12_07REC (Example) Uses built in feature to call “lucreate -n S10_12_07REC” behind scenes if not already present NOTE: Leave “lucreate” params blank (if you do specify options, the will be appended after -n $ABEName) Solaris 10 and Live Upgrade: Alternate Boot Environment Creation via Operational Profile (script) The Alternate Boot Environment is to be created via custom, user-supplied script, which does whatever is needed for the system where Live Upgrade will be used. Operational Profile, which provides the script to create an ABE: Very similar to the automatic case, but with a Script (Operational Profile), which is used to create the ABE Relies on user-supplied script in the form of an Operational Profile Could be used to prepare an ABE based on a UFS root in a slice, or on a separate device (e.g. by breaking a mirror first) – it is up to the script author to do the right thing! EXAMPLE: Same result as the ZFS case, but illustrating the Operational Profile (e.g. script) approach to call: # lucreate -n S10_1207REC NOTE: OC special variable is $ABEName Boot Environment Profile, which references the Operational Profile Script = Operational Profile on this screen Refers to Operational Profile shown in the previous section The user-supplied S10_Create_BE Operational Profile will be run The Operational Profile must send a non-zero exit code if there is a problem (so that the OS Update job will not proceed) Solaris 10 OS Update Profile (to provide the actual patch specifications) Solaris 10 Baseline “Recommended” chosen for “Install” Solaris 10 OS Update Plan (two-steps in this case) “Create a Boot Environment” + “Update OS” are chosen. Using Ops Center to patch Solaris 11 with Boot Environments (as needed) Create a Solaris 11 OS Update Profile containing the packages that make up your standard build ACTUALLY deploy the Solaris 11 OS Update Profile BE will be created if needed (or you can stipulate no BE) BE name will be auto-generated (if needed), or you may specify a BE name Check the job status for each node, resolving any issues found Check if a BE was created; if so, activate the new BE Activate = Reboot to the BE, making the new BE the active BE Ops Center does not separate BE activate from reboot NOTE: Not every Solaris 11 OS Update will require a new BE, so a reboot may not be necessary. Solaris 11: Auto BE Create (as Needed -- let Ops Center decide) BE to be created as needed BE to be named automatically Reboot (if necessary) deferred to separate step Solaris 11: OS Profile Solaris 11 “entire” chosen for a particular SRU Solaris 11: OS Update Plan (w/BE)  “Create a Boot Environment” + “Update OS” are chosen. Summary: Solaris 10 Live Upgrade, Alternate Boot Environments, and their equivalents on Solaris 11 can be very powerful tools to help minimize the downtime associated with updating your servers.  For very old Solaris, there are some important prerequisites to adhere to, but once the initial preparation is complete, Live Upgrade can be used going forward.  For Solaris 11, the built-in Boot Environment handling is leveraged directly by the Image Packaging System, and the result is a much more straight forward way to patch, and far fewer prerequisites to satisfy in getting there.  Ops Center simplifies using either approach, and helps you improve consistency from system to system, which ultimately helps you improve the overall up-time across all the Solaris systems in your environment.

  • Cryptographic Validation Explained

    - by MarkPearl
    We have been using LogicNP’s CryptoLicensing for some of our software and I was battling to understand how exactly the whole process worked. I was sent the following document which really helped explain it – so if you ever use the same tool it is well worth a read. Licensing Basics LogicNP CryptoLicensing For .Net is the most advanced and state-of-the art licensing and copy protection system you can use for your software. LogicNP CryptoLicensing System uses the latest cryptographic technology to generate and validate licenses. The cryptographic algorithm used is the RSA algorithm which consists of a pair of keys called as the generation key and the validation key. Data encrypted using the generation key can only be decrypted using the corresponding validation key. How does cryptographic validation work? When a new license project is created, a unique validation-generation key pair is created for the project. When LogicNP CryptoLicensing For .Net generates licenses, it encrypts the license settings using the generation key. The validation key can be safely distributed with your software and is used during validation. During license validation, LogicNP CryptoLicensing For .Net attempts to decrypt the encrypted license code using the validation key. If the decryption is successful, this means that the data was encrypted using the generation key, since only the corresponding validation key can decrypt data encrypted with the generation key. This further means that not only is the license valid but that it was generated by you and only you since nobody else has access to the generation key. Generation Key This key is used by CryptoLicensing Generator to generate encrypted license codes. This key is stored in the license project file, so the license project file must be kept secure and confidential and must be accorded the same care as any other critical asset such as source code. Validation Key This key is used for validating generated license codes. It is the same key displayed in the 'Get Validation Key And Code' dialog (Ctrl+K) and is used by your software when validating license codes (using LogicNP.CryptoLicensing.dll). Unlike the generation key, it is not necessary to keep this key secure and confidential. Note that the generation key pair is stored in the project file created by LogicNP CryptoLicensing For .Net, so it is very important to backup this file and to keep it secure. Once the file is lost, it is not possible to retrieve the key pair. FAQ Do I use the same validation key to validate all license codes? Yes, the validation key (and generation key) for the project remains the same; you use the same key to validate all license codes generated using the project. You can retrieve the validation key using the "Project" menu --> "Get Validation Key & Code" menu item. Can license codes generated using generation key from one project be validated using validation key of another project? No! Q. Is every generated license code unique? A. Yes, every license code generated by CryptoLicensing is guaranteed to be unique, even if you generate thousands of codes at a time. Q. What makes CryptoLicensing so secure? A. CryptoLicensing uses the latest cryptographic technology to generate and validate licenses. The cryptographic algorithm used is the RSA asymmetric key algorithm which can use upto 3072-bit keys. Given current computing power, it takes years to break a 3072-bit key. Q. Is is possible for a hacker to develop a keygen for my software? A. Impossible. The cryptographic algorithm used by CryptoLicensing consists of a pair of keys called as the generation key and the validation key. Data encrypted with one key can only be decrypted by the other key and vice versa. Licenses are generated using the generation key and validated using the validation key. Without the generation key, it is impossible to generate valid licenses. Q. What is the difference between validation key and generation key? Generation Key This key is used by CryptoLicensing Generator to generate encrypted license codes. This key is stored in the license project file, so the license project file must be kept secure and confidential and must be accorded the same care as any other critical asset such as source code. Validation Key This key is used for validating generated license codes. It is the same key displayed in the 'Get Validation Key And Code' dialog (Ctrl+K) and is used by your software when validating license codes (using LogicNP.CryptoLicensing.dll). Unlike the generation key, it is not necessary to keep this key secure and confidential. Q. Do I have to include the license project file (.licproj) with my software? A. No!!! This goes against the very essence of the security of the asymmetric cryptographic scheme because the project file contains both the validation and generation key. With your software, you only need to include the validation key which will be used to validate licenses generated by CryptoLicensing using the generation key. The license project file should be treated as any other valuable and confidential asset such as your source code. Q. Does the license service need the license project file? A. Yes. The license project file is needed whenever new licenses are generated (via the UI, via the API or via the license service). As just one example, the license service generates new machine-locked licenses when activated licenses are presented to it for activation, therefore the license service needs the license project file. Q. Is it possible to embed my own data in the generated licenses? A. Yes. You can embed any amount of additional data in the licenses. This data will have the same amount of security as the license code itself and will be tamper-proof. The embedded user data can be retrieved from your software. Q. What additional steps can I take to ensure that my software does not get cracked? A. There are many methods and techniques which can make it extremely difficult for a hacker to crack your software. See Writing Effective License Checking Code And Designing Effective Licenses for more information. Q. Why is the license service not working? A. The most common cause is not setting the CryptoLicense.LicenseServiceURL property before trying to validate a license. Make sure that this property is set to the correct URL where your license service is hosted. The most common cause after this is that the license project file on the web server where your license service is hosted is not the latest. This happens if you make changes to the license project (for example, set the 'Enable With Serials' setting for a profile), but don't upload the updated project file to your web server. Q. Why are my serials not working? Serial codes require the user of a license service. See Using Serial Codes for more details. Also see the earlier question 'Why is the license service not working?' Q. Is the same validation key used to validate license codes generated from different profiles. A. Yes. Profiles are just pre specified license settings for quickly generating licenses having those settings. The actual license code is still generated using the license project's cryptographic generation key and thus, can be validated using the project's validation key. Q. Why are changes made to a profile not getting saved? A. Simply changing license settings via UI and saving the license project does not save those license settings to the active profile. You must first save the license settings to a profile using the Save/Save As command from the Profiles menu (see above). Q. Why is validation of activated licenses failing from CryptoLicensing Generator, but works from my software? A. Make sure that you have specified the URL of the license service using the Project Properties Dialog. Also see the earlier question 'Why is the license service not working?' Q. How can I extend the trial period of my customer? A. To extend the evaluation period of the customer, simply send him a new license code specifying the desired evaluation limits. Evaluation information such as the current used days, executions, etc are stored in garbled form in a registry location which is derived from the license code. Therefore, when a new license code is used, the old evaluation information will not be used and a new evaluation period will be started.
