  • Lingering database-connections from Feng Office

    - by Bobby
    I've installed Feng Office on our main server which is working perfectly so far. Unfortunately it seems like there's a problem with the connection to the MySQL-Database. While the connection itself works fine, it's the reuse/pooling of connections which seems to be bugged. There are lingering/sleeping connections to the server from Feng Office which won't close and don't get reused after some time (120 seconds). Of course those lingering processes/connections are piling up pretty fast. I've found a thread at the forums about this behavior, but the suggested fix is already applied (by default). I'm sure this is just a configuration issue, but I'm a little clue less because Feng is besides a MediaWiki, a DokuWiki and homebrewed PHP applications the only one with this issue. The setup is a Microsoft Windows 2003 Server with MySQL 5.0.26 and Apache 2.2. Where can I start looking for clues why this is happening and how do I get rid of lingering MySQL-Connections?

  • Amazon EC2- micro-instance vs single small/medium instance

    - by shashankaholic
    I have a chat application using stack of Openfire, Tomcat6 and MySQL. Currently, i have installed all these servers on single Linux micro-instance(613 MB memory). Even in low user base 10-20 i am encountering CPU overload which is quite obvious here. As, i am new to Amazon EC2 can somebody suggest me how to scale up my architecture according to traffic use? should i use separate micro instances for every app server(openfire,mysql,tomcat6) should i use single small or medium instance for whole server stack. Some factors in context: high reliance on MYSQL high memory usage due to file transfer web-application interacting with other Amazon service like S3,SES

  • Unable to edit/delete/move /etc/my.cnf - Permission denied

    - by FlourishDNA
    I am trying to edit /etc/my.cnf as root user via ssh and I get following error while trying to save it I ma making changes to my.cnf as I want to tweak some values in my.cnf to meet Magento requirement like changing key_buffer_size= to higher value (128M). I assigned the value 128M to key_buffer_size= and tried to save it and then got an error. "Error writing /etc/my.cnf: Permission denied" I cant even restart MySQL successfully. [root@flourish ~]# service mysqld restart Stopping mysqld: [ OK ] MySQL Daemon failed to start. Starting mysqld: [FAILED] I can even delete or replace it with the fresh one. I tried uninstalling MySQL and re-installing but nothing worked. Permission -rw-r--r-- and Owner/Group root/root I hope there is some answer to this problem.

  • Difference between key_buffers and recommendation

    - by Typeoneerror
    I'm looking to add a bit of memory to MySQL on a Linode VPS server on which I've got a small facebook (canvas app) PHP app using MySQL running. I'm not super familiar with MySQL optimization so I'm hoping to find a simple answer. I think I want to increase the key_buffer size (the default is 16M) to something like 32M to start, but I'm not sure if I need to tweak anything else as well. All I've done so far is increase the query_cache_size to 32M from 16M. There's also key_buffer under [mysqld] and key_buffer under [isamchk]. What are the difference between those two? If I have Linode 2048MB (http://www.linode.com) VPS, what would recommend I set the buffers to? I don't expect this site to have tons of visitors, but I'd like it to be as optimized as possible. Definitely way more heavy on the database access than PHP and very few HTTP requests.

  • The good SQL database to process a lot of data?

    - by Dorian
    I have to process like 10-100 millions records. I have to give the data to the client when it's finish. The data is givent as SQL requests to execute in the database. He have a powerful server with MySQL, I think it will be fast enough. The issue is my computer is not as powerful as his server, so I would like to use an other SQL server who is compatible (I export his database and import it in my computer) with MySQL but more powerful. What should I use? Or am I doomed to use MySQL?

  • Web-Server directory permissions

    - by MLS
    Hello All, I would like some help understanding web-server directory permissions. Apache, CentOS, PHP, Mysql Example, I have multiple sites in /var/www/html They are in paths like: /var/www/html/www_domainname_com inside each site I might have a path like /lib/mysql/ like PHP connect stuff, database config, etc. What should me permissions be so that someone cannot just browse to that directory? Should I just .htaccess them? I have apache:apache as the owner of all my web directories. Can I prevent someone from crawling certain directories of my web-server? I have a robots.txt, but what is to say the crawler obeys it? So to sum up: 1. What is the best owner/permission set for my sensitive files that the web-server or php or mysql needs, but I dont want people browsing to? Can I prevent straight out crawling of portions?

  • Escaping %’s in file-/folder-names at the command-line

    - by Synetech
    Does anybody of a way to access files and directories that have a % in their name (which is valid) from the command-line? Specifically, if there are two %’s and the text between them happens to correspond to an environment variable. For example, if there is a file called C:\blah\%temp%.txt or a folder called C:\Program Files\%temp%\, none of the following will work because the variable gets expanded: > dir "c:\blah\%temp%.txt" > dir "c:\blah\^%temp^%.txt" > dir "c:\blah\%%temp%%.txt" > dir "c:\blah\\%temp\%.txt" > dir "c:\program files\%temp%" > dir "c:\program files\^%temp^%" > dir "c:\program files\%%temp%%" > dir "c:\program files\\%temp\%" Using wildcards will work, but does not uniquely select the file/folder and may include others: > dir "c:\blah\?temp?.txt"        (also shows ztempz.temp, 1tempa.txt, etc.) > dir "c:\program files\?temp?"   (likewise) (This is frustrating because every now and then—usually when Explorer is restarted for whatever reason—the environment variables stop expanding and some places where they are used end up creating files or directories with the environment variable in it. For example, because I configured Chromium to store its cache in a subdirectory of %temp%, if the variable expands, it is fine, but when it doesn’t, Chromium creates a directory called %temp% under its own directory and stores the cache—which can get large—there. I want to add a line to my temp-/junk-file cleaning script to automatically delete that folder if it exists, but I cannot figure out how to access it from the command-line without resorting to wildcards.)

  • Sharepoint (active directory account creation mode) - Using STSADM

    - by vivek m
    This question is regarding using STSADM command to create new site collection in Active Directory Account creation mode. My setup is like this- I have 2 virtual PCs in a Windows XP Pro SP3 host. Both VPCs are Windows Server 2003 R2. One VPC acts as the DC, DNS Server, DHCP server, has Active Directory installed and is also the Database Server. The other VPC is the domain member and it is the IIS web server, POP/SMTP server and it has WSS 3.0 installed. I created a new site using the GUI in Central Admin page. For creating a site collection under the newly created site, I needed to use the STSADM command line tool since it cannot be done from Central Admin page in Active Directory Account creation mode.

  • Replacement Text Syntax for JavaScript’s String.replace()

    - by Jan Goyvaerts
    A RegexBuddy user told me that he couldn’t easily find a detailed explanation of the replacement text syntax supported by the String.replace() function in JavaScript. I had to admin that my own web page about JavaScript’s regular expression support was also lacking. I’ve now added a new Replacement Syntax section that has all the details. I’ll summarize it here: $1: Text matched by the first capturing group or the literal text $1 if the regex has no capturing groups. $99: Text matched by the 99th capturing group if the regex has 99 or more groups. Text matched by the 9th capturing group followed by a literal 9 if the regex has 9 or more but less than 99 groups. The literal text $99 if the regex has fewer than 9 groups. $+: Text matched by the highest-numbered capturing group. Replaced with nothing if the highest-numbered group didn’t participate in the match. $&: Text matched by the entire regex. You cannot use $0 for this. $` (backtick): Text to the left of the regex match. $' (single quote): Text to the right of the regex match. $_: The entire subject string.

  • Amazon Kindle Fire User Agent String

    - by Gopinath
    Today I was searching for Amazon Kindle Fire user agent string so that I can trick websites as if I’m browsing using Kindle Fire. To my surprise I found the following two variants of user agents listed on blogs but not sure which one is right or if Kindle Fire generating two types of User Agent strings. The first one is given by the prominent blogger and WSJ tech columnist Amit Agarwal and I vote for him as he is a highly reputed person. Mozilla/5.0 (Linux; U; Android 2.3.4; en-us; Kindle Fire Build/GINGERBREAD) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1 The second variant is found on this website and I’m not sure about the authority of the blogger.

  • String manipulation functions in SQL Server 2000 / 2005

    - by Vipin
    SQL Server provides a range of string manipulation functions. I was aware of most of those in back of the mind, but when I needed to use one, I had to dig it out either from SQL server help file or from google. So, I thought I will list some of the functions which performs some common operations in SQL server. Hope it will be helpful to you all. Len (' String_Expression' ) - returns the length of input String_Expression. Example - Select Len('Vipin') Output - 5 Left ( 'String_Expression', int_characters ) - returns int_characters characters from the left of the String_Expression.     Example - Select Left('Vipin',3), Right('Vipin',3) Output -  Vip,  Pin  LTrim ( 'String_Expression' ) - removes spaces from left of the input 'String_Expression'  RTrim ( 'String_Expression' ) - removes spaces from right of the input 'String_Expression' Note - To removes spaces from both ends of the string_expression use Ltrim and RTrim in conjunction Example - Select LTrim(' Vipin '), RTrim(' Vipin ') , LTrim ( RTrim(' Vipin ')) Output - 'Vipin ' , ' Vipin' , 'Vipin' (Single quote marks ' ' are not part of the SQL output, it's just been included to demonstrate the presence of space at the end of string.) Substring ( 'String_Expression' , int_start , int_length ) - this function returns the part of string_expression. Right ( 'String_Expression', int_characters ) - returns int_characters characters from the right of the String_Expression.

  • Using "gedit", a string of errors occours

    - by Kumuluzz
    I'm trying to program some small programs in C in terminal and gedit. But everytime i use gedit then a string of errors occours. When i open a new file nothing happens. But in the exact same moment i save the file, then a string of erros coour. Also if i open an already existing file (not a new one), then when the gedit window opens the old file all the lines of errors are writen. In both cases in less than a second and nothing more happens. An example to the error: "error: line 35272: 0 is wrong flag id". They are all similar to this, except the line number is different. There are like 50 of them. I'm running 11.10, just installed it a couple of days again (yes, i'm a newbie) and i've updated all the files recently. I've tried reinstalling gedit via: sudo apt-get --reinstall install gedit It kinda made it worse, now a lot of the lines are shown twice. So now it goes (this is a copy of the first lines of error): error: line 6787: 0 is wrong flag id error: line 10034: 0 is wrong flag id error: line 10034: 0 is wrong flag id error: line 11351: 0 is wrong flag id error: line 11351: 0 is wrong flag id error: line 11849: 0 is wrong flag id error: line 11849: 0 is wrong flag id error: line 15609: 0 is wrong flag id error: line 15609: 0 is wrong flag id error: line 19814: 0 is wrong flag id

  • How to implement string matching based on a pattern

    - by Vincent Rischmann
    I was asked to build a tool that can identify if a string match a pattern. Example: {1:20} stuff t(x) {a,b,c} would match: 1 stuff tx a 20 stuff t c It is a sort of regex but with a different syntax Parentheses indicate an optional value {1:20} is a interval; I will have to check if the token is a number and if it is between 1 and 20 {a,b,c} is just an enumeration; it can be either a or b or c Right now I implemented this with a regex, and the interval stuff was a pain to do. On my own time I tried implementing some kind of matcher by hand, but it turns out it's not that easy to do. By experimenting I ended up with a function that generates a state table from the pattern and a state machine. It worked well until I tried to implement the optional value, and I got stuck and how to generate the state table. After that I searched how I could do this, and that led me to stuff like LL parser, LALR parser, recursive-descent parser, context-free grammars, etc. I never studied any of this so it's hard to know what is relevant here, but I think this is what I need: A grammar A parser which generates states from the grammar and a pattern A state machine to see if a string match the states So my first question is: Is this right ? And second question, what do you recommend I read/study to be able to implement this ?

  • High-level strategy for distinguishing a regular string from invalid JSON (ie. JSON-like string detection)

    - by Jonline
    Disclaimer On Absence of Code: I have no code to post because I haven't started writing; was looking for more theoretical guidance as I doubt I'll have trouble coding it but am pretty befuddled on what approach(es) would yield best results. I'm not seeking any code, either, though; just direction. Dilemma I'm toying with adding a "magic method"-style feature to a UI I'm building for a client, and it would require intelligently detecting whether or not a string was meant to be JSON as against a simple string. I had considered these general ideas: Look for a sort of arbitrarily-determined acceptable ratio of the frequency of JSON-like syntax (ie. regex to find strings separated by colons; look for colons between curly-braces, etc.) to the number of quote-encapsulated strings + nulls, bools and ints/floats. But the smaller the data set, the more fickle this would get look for key identifiers like opening and closing curly braces... not sure if there even are more easy identifiers, and this doesn't appeal anyway because it's so prescriptive about the kinds of mistakes it could find try incrementally parsing chunks, as those between curly braces, and seeing what proportion of these fractional statements turn out to be valid JSON; this seems like it would suffer less than (1) from smaller datasets, but would probably be much more processing-intensive, and very susceptible to a missing or inverted brace Just curious if the computational folks or algorithm pros out there had any approaches in mind that my semantics-oriented brain might have missed. PS: It occurs to me that natural language processing, about which I am totally ignorant, might be a cool approach; but, if NLP is a good strategy here, it sort of doesn't matter because I have zero experience with it and don't have time to learn & then implement/ this feature isn't worth it to the client.

  • How can I make this script output each categories item per category [closed]

    - by Duice352
    Ok so here is the deal currently this script outputs all the products in a parent category as well as the products in the child categories. What i would like to do is seperate the output based on child categories. All the child categories are in the array $children and the string $childs. The parent category is the first array element of $children with the following ones being the actual children. The category names are stored in the database $result as " $cat_name ". I want to first Display the cat_name then the products that fall in that category and then display the next child cat_name and items, ect. Any suggestions of how to manipulate the while loop that cylcles through the rows? <?php $productsPerRow = 3; $productsPerPage = 15; //$productList = getProductList($catId); $children = array_merge(array($catId), getChildCategories(NULL, $catId)); $childs = ' (' . implode(', ', $children) .

  • Best way to manipulate and compare strings

    - by vtortola
    I'm developing a REST service, so a request could be something like this: /Data/Main/Table=Customers/ I need to get the segments one by one, and for each segment I will decide wich object I'm going to use, after I'll pass to that object the rest of the query so it can decide what to do next. Basically, the REST query is a path on a tree :P This imply lots String operations (depending on the query complexity), but StringBuilder is useful just for concatenations and remove, you cannot perform a search with IndexOf or similar. I've developed this class that fulfill my requirement, but the problem is that is manipulating Strings, so every time I get one segment ... I'll create extra Strings because String is an inmutable data type: public class RESTQueryParser { String _query; public RESTQueryParser(String query) { _query = query; } public String GetNext() { String result = String.Empty; Int32 startPosition = _query.StartsWith("/", StringComparison.InvariantCultureIgnoreCase) ? 1 : 0; Int32 i = _query.IndexOf("/", startPosition, StringComparison.InvariantCultureIgnoreCase) - 1; if (!String.IsNullOrEmpty(_query)) { if (i < 0) { result = _query.Substring(startPosition, _query.Length - 1); _query = String.Empty; } else { result = _query.Substring(startPosition, i); _query = _query.Remove(0, i + 1); } } return result; } } The server should support a lot of calls, and the queries could be huge, so this is gonna be a very repetitive task. I don't really know how big is the impact on the memory and the performance, I've just readed about it in some books. Should I implement a class that manage a Char[] instead Strings and implement the methods that I want? Or should be ok with this one? Regular expressions maybe?

  • Using a join with three tables when a field might be null

    - by John
    Hello, The code below works great. It combines data from two MySQL tables. I would like to modify it by pulling in some data from a third MySQL table called "comment." In the HTML table below, "title" is a field in the MySQL table "submission." Every "title" has a corresponding "submissionid" field. The field "submissionid" is also found in the "comment" MySQL table. In the HTML table below, I would like "countComments" to equal the number of times a field called "commentid" appears in the MySQL table "comment" for any given "submissionid," where the "submissionid" is the same in both the "submission" and "comment" tables, and where the "submissionid" corresponds to the "title" being used. Here's the catch: if there is no row in the MySQL table "comment" that corresponds with the "submissionid" being used for "table", I would like "countComments" to equal to zero. How can I do this? Thanks in advance, John $sqlStr = "SELECT s.loginid, s.title, s.url, s.displayurl, l.username FROM submission AS s, login AS l WHERE s.loginid = l.loginid ORDER BY s.datesubmitted DESC LIMIT 10"; $result = mysql_query($sqlStr); $arr = array(); echo "<table class=\"samplesrec\">"; while ($row = mysql_fetch_array($result)) { echo '<tr>'; echo '<td class="sitename1"><a href="http://www.'.$row["url"].'">'.$row["title"].'</a></td>'; echo '</tr>'; echo '<tr>'; echo '<td class="sitename2"><a href="http://www...com/sandbox/members/index.php?profile='.$row["username"].'">'.$row["username"].'</a><a href="http://www...com/sandbox/comments/index.php?submission='.$row["title"].'">'.$row["countComments"].'</a></td>'; echo '</tr>'; } echo "</table>";

  • Multiplayer card game using PHP/Ajax and mysql

    - by Alireza Seifi
    I am designing a map game, using PHP and MYSQL. I don't know how to make the players who sign-in to the website to see other players who are also connected to the site and be able to chat with one another. I want to design the game in such a way that 2 players can play with each other and be able to send messages during the game while others groups are playing at the same time. I have designed the map game successfully, but the problem is making the player 1 who log-in to site to see the player 2 who will also log-in and both can get connected to play each other. http://i.stack.imgur.com/YyCPG.png I will appreciate your responses.

  • Ubuntu 13.10 gives "Package 'libapache2-mod-auth-mysql' has no installation candidate" error

    - by John Crawford
    I'm trying to install my LAMP environment on Ubuntu 13.10 using my script file that can be found here. That script worked for Ubuntu 12.04, Ubuntu 13.04 but when I try it on Ubuntu 13.10 it gives the following error: E: Package 'libapache2-mod-auth-mysql' has no installation candidate Any idea on how to fix this? Note, I do want this package to be installed. EDIT: I've found out now that the reason this could not be installed was because it needed the following two packages that were missing: libmysqlclient16 and apache2.2-common. Do I just need to install these packages or were they removed for a reason?
