  • unable to inject seam cache provider

    - by Joshua
    Env: Seam 2.2, ehcache-core 2.1.0 I tried injecting the CacheProvider using the following call in my bean scoped for session @In CacheProvider cacheProvider; WEB-INF\components.xml contains the following line to enable the cache provider <cache:eh-cache-provider/> The above configuration seems to return a null value for the cache provider Using the cache provider like this CacheProvider cacheProvider = CacheProvider.instance(); throws the following warning 15:29:27,586 WARN [CacheManager] Creating a new instance of CacheManager using the diskStorePath "C:\DOCUME~1\user5\LOCALS~1\Temp\" which is already used by an existing CacheManager. The source of the configuration was net.sf.ehcache.config.generator.Configuratio nSource$DefaultConfigurationSource@15ed0f9. The diskStore path for this CacheManager will be set to C:\DOCUME~1\user5\LOCALS ~1\Temp\\ehcache_auto_created_1276682367586. To avoid this warning consider using the CacheManager factory methods to create a singleton CacheManager or specifying a separate ehcache configuration (ehcache .xml) for each CacheManager instance. What am I missing here?

  • Do condition variables still need a mutex if you're changing the checked value atomically?

    - by Joseph Garvin
    Here is the typical way to use a condition variable: // The reader(s) lock(some_mutex); if(protected_by_mutex_var != desired_value) some_condition.wait(some_mutex); unlock(some_mutex); // The writer lock(some_mutex); protected_by_mutex_var = desired_value; unlock(some_mutex); some_condition.notify_all(); But if protected_by_mutex_var is set atomically by say, a compare-and-swap instruction, does the mutex serve any purpose (other than that pthreads and other APIs require you to pass in a mutex)? Is it protecting state used to implement the condition? If not, is it safe then to do this?: // The writer protected_by_mutex_var = desired_value; some_condition.notify_all(); With the writer never directly interacting with the reader's mutex? If so, is it even necessary that different readers use the same mutex?

  • Is it a good idea to cache data from web services into a database?

    - by Thierry Lam
    Let's assume that Stackoverflow offers web services where you can retrieve all the questions asked by a specific user. A request to get all question from user A can result in the following json output: { { "question": "What is rest?", "date_created": "20/02/2010", "votes": 1, }, { "question": "Which database to use for ...", "date_created": "20/07/2009", "votes": 5, }, } If I want to manipulate and present the data in any ways that I want, will it be wise to dump it in a local database? At some point, I will also want to retrieve all answers for each question and store them in a local database. The workflow that I'm thinking is: User logs in. Web services retrieve all questions asked by the logged in user, dump them in a local database. User wants all answers for a specific question, another web service does the retrieval and dump them in a local database. After user logs out, delete from the local database all questions and answers from that user.

  • replace only one variable in web.py templates

    - by Asterisk
    I am passing variable to template in web.py and have the same condition in some places. Like this: $if myvar=="string1": $passed argument1 ............ $if myvar =="striung2": $passed argument2 If say myvar is "string1" and I pass passed = "AAA" then I have AAA argument1 on my page, but the other if statements get replaced by empty string? How to avoid that? I.e. how to leave other statements intact?

  • Unable to save to wincache from cakePHP shell

    - by Phillaf
    I'm trying to retrieve the weather from wunderground.com through their API, and store it in wincache. For testing purposes I made this function in the News model: public function updateWeather(){ $results = file_get_contents('http://api.wunderground.com/api/**api_key**/conditions/q/CA/Montreal.json'); $results = json_decode($results); return Cache::write('weather', $results); } It works fine when I call this from the controller. However, I can't figure why that same function doesn't work when called from the console. I made this shell in order to eventually add this to windows task scheduler. class WeatherShell extends AppShell { public $uses = array('News'); public function main() { $this->News->updateWeather(); } } When running this, I see that $results is correctly populated. I get 'true' from Cache::write(), however, I get 'false' when trying to read. What subtlety am I missing?

  • Security implications of writing files using PHP

    - by susmits
    I'm currently trying to create a CMS using PHP, purely in the interest of education. I want the administrators to be able to create content, which will be parsed and saved on the server storage in pure HTML form to avoid the overhead that executing PHP script would incur. Unfortunately, I could only think of a few ways of doing so: Setting write permission on every directory where the CMS should want to write a file. This sounds like quite a bad idea. Setting write permissions on a single cached directory. A PHP script could then include or fopen/fread/echo the content from a file in the cached directory at request-time. This could perhaps be carried out in a Mediawiki-esque fashion: something like index.php?page=xyz could read and echo content from cached/xyz.html at runtime. However, I'll need to ensure the sanity of $_GET['page'] to prevent nasty variations like index.php?page=http://www.bad-site.org/malicious-script.js. I'm personally not too thrilled by the second idea, but the first one sounds very insecure. Could someone please suggest a good way of getting this done?

  • IList<Item> Collection Class accessing database

    - by Mike
    Hi, I have a database with Users. Users have Items. These Items can change actively. How do you access the items in a collection type format? For the user, I fill all the user properties at the time of instantiation. If I load the user's items at the time of the instantiation, and the items change, they will have old data. I was thinking, maybe I need an ItemCollection class and have that a field/property apart of the user class, that way to traverse all the user's items I could use a foreach loop. So, my question is, what is the best practice/best way of accessing the items from a database using some sort of collection? On accessing the particular Item, it needs to get the latest database information, and when the user does do a foreach loop, the latest item information must be available. I.e. What I'm trying to do Console.WriteLine(User.Items[3].ID); returns 5. //this updates the item information and saves it to the database. User.Items[3].ID = 13; //Add a new item to the database. User.Items.Add(new Item { id = 17}); foreach (Item item in User.Items) { //this would traverse all items in the database. //not some cached copy at the time of instantiation of the user. }

  • Choose variable based on users choice from picklist.

    - by Kelbizzle
    I have this form. Basically what I want is to send a auto-response with a different URL based on what the user picks in the "attn" picklist. I've been thinking I could have a different variable for each drop down value. It will then pass this variable on to the mail script that will choose which URL to insert inside the auto response that is sent. It gives me a headache thinking about it sometimes. What's the easiest way to accomplish this? Am I making more work for myself? I really don't know because I'm no programmer. Thanks in advance! Here is the form: <form name="contact_form" method="post" action="sendemail_reports.php" onsubmit="return validate_form ( );"> <div id='zohoWebToLead' align=center> <table width="100%" border="0" align="center" cellpadding="0" cellspacing="0" class="txt_body"> <table border=0 cellspacing=0 cellpadding=5 width=480 style='border-bottom-color: #999999; border-top-color: #999999; border-bottom-style: none; border-top-style: none; border-bottom-width: 1px; border-top-width: 2px; background-color:transparent;'> <tr> <td width='75%'><table width=480 border=0 cellpadding=5 cellspacing=0 style='border-bottom-color: #999999; border-top-color: #999999; border-bottom-style: none; border-top-style: none; border-bottom-width: 1px; border-top-width: 2px; background-color:transparent;'> <input type="hidden" name="ip" value="'.$ipi.'" /> <input type="hidden" name="httpref" value="'.$httprefi.'" /> <input type="hidden" name="httpagent" value="'.$httpagenti.'" /> <tr></tr> <tr> <td colspan='2' align='left' style='border-bottom-color: #dadada; border-bottom-style: none; border-bottom-width: 2px; color:#000000; font-family:sans-serif; font-size:14px;'><strong>Send us an Email</strong></td> </tr> <tr> <td nowrap style='font-family:sans-serif;font-size:12px;font-weight:bold' align='right' width='25%'> First Name   : </td> <td width='75%'><input name='visitorf' type='text' size="48" maxlength='40' /></td> </tr> <tr> <td nowrap style='font-family:sans-serif;font-size:12px;font-weight:bold' align='right' width='25%'>Last Name   :</td> <td width='75%'><input name='visitorfl' type='text' size="48" maxlength='80' /></td> </tr> <tr> <td nowrap style= 'font-family:sans-serif;font-size:12px;font-weight:bold' align='right' width='25%'> Email Adress  : </td> <td width='75%'><input name='visitormail' type='text' size="48" maxlength='100' /></td> </tr> <tr> <td nowrap style='font-family:sans-serif;font-size:12px;font-weight:bold' align='right' width='25%'> Phone   : </td> <td width='75%'><input name='visitorphone' type='text' size="48" maxlength='30' /></td> </tr> <td nowrap style='font-family:sans-serif;font-size:12px;font-weight:bold' align='right' width='25%'> Subject   : </td> <td width='75%'><select name="attn" size="1"> <option value=" Investment Opportunities ">Investment Opportunities </option> <option value=" Vacation Rentals ">Vacation Rentals </option> <option value=" Real Estate Offerings ">Real Estate Offerings </option> <option value=" Gatherings ">Gatherings </option> <option value=" General ">General </option> </select></td> <tr> <td nowrap style= 'font-family:sans-serif;font-size:12px;font-weight:bold' align='right' width='25%'> Message   :<br /> <em>(max 5000 char)</em></td> <td width='75%'><textarea name='notes' maxlength='5000' cols="48" rows="3"></textarea></td> </tr> <tr> <td colspan=2 align=center style=''><input name='save' type='submit' class="boton" value=Send mail /> &nbsp; &nbsp; <input type='reset' name='reset' value=Reset class="boton" /></td> </tr> </table></td> </tr> </table> </div> </form> Here is the mail script: <?php //the 3 variables below were changed to use the SERVER variable $ip = $_SERVER['REMOTE_ADDR']; $httpref = $_SERVER['HTTP_REFERER']; $httpagent = $_SERVER['HTTP_USER_AGENT']; $visitorf = $_POST['visitorf']; $visitorl = $_POST['visitorl']; $visitormail = $_POST['visitormail']; $visitorphone = $_POST['visitorphone']; $notes = $_POST['notes']; $attn = $_POST['attn']; //additional headers $headers = 'From: Me <[email protected]>' .

  • Any HTTP proxies with explicit, configurable support for request/response buffering and delayed conn

    - by Carlos Carrasco
    When dealing with mobile clients it is very common to have multisecond delays during the transmission of HTTP requests. If you are serving pages or services out of a prefork Apache the child processes will be tied up for seconds serving a single mobile client, even if your app server logic is done in 5ms. I am looking for a HTTP server, balancer or proxy server that supports the following: A request arrives to the proxy. The proxy starts buffering in RAM or in disk the request, including headers and POST/PUT bodies. The proxy DOES NOT open a connection to the backend server. This is probably the most important part. The proxy server stops buffering the request when: A size limit has been reached (say, 4KB), or The request has been received completely, headers and body Only now, with (part of) the request in memory, a connection is opened to the backend and the request is relayed. The backend sends back the response. Again the proxy server starts buffering it immediately (up to a more generous size, say 64KB.) Since the proxy has a big enough buffer the backend response is stored completely in the proxy server in a matter of miliseconds, and the backend process/thread is free to process more requests. The backend connection is immediately closed. The proxy sends back the response to the mobile client, as fast or as slow as it is capable of, without having a connection to the backend tying up resources. I am fairly sure you can do 4-6 with Squid, and nginx appears to support 1-3 (and looks like fairly unique in this respect). My question is: is there any proxy server that empathizes these buffering and not-opening-connections-until-ready capabilities? Maybe there is just a bit of Apache config-fu that makes this buffering behaviour trivial? Any of them that it is not a dinosaur like Squid and that supports a lean single-process, asynchronous, event-based execution model? (Siderant: I would be using nginx but it doesn't support chunked POST bodies, making it useless for serving stuff to mobile clients. Yes cheap 50$ handsets love chunked POSTs... sigh)

  • [PHP] Dots and spaces in variable names from external sources are converted to underscores

    - by Brandon
    Trying a bit of AJAX, and I find that much of my data is littered with underscores! Documentation confirms that this is working as intended. Any way to pass my form information to PHP in tact? I'm using code igniter, so my pass looks like /controller/function/variable, receiving controller: controller{ function($v=0){#what once was hello world is now hello_world...} } I can't very well do an undo, data might contain an underscore. Thanks, Brandon

  • PHP: variable-length argument list by reference?

    - by GetFree
    Is it possible to create a PHP function that takes a variable number of parameters all of them by reference? It doesn't help me a function that receives by reference an array of values nor a function that takes its arguments wrapped in an object because I'm working on function composition and argument binding. Don't think about call-time pass-by-reference either. That thing shouldn't even exist.

  • PHP: form action on same page, still show same until refresh

    - by Karem
    Yes, Im having a little edit profile page, index.php?mode=profile. Lets take the username in the editprofile form as example. The username is already in the username-field. So i changed from "Peter" to "Tom" and press save. The action is ?mode=profile&edit=true. So now when i have pressed save it has updated the column in the db from Peter to Tom. But this field keeps having the value "Peter" until if i do press refresh (or f5), then "Tom" will appear. Like it hasnt updated in the database anything, although it did but it still shows Peter until next refresh.. like it caches, but it shouldnt cache nothing? Any help on this? Is it because its on the same "page" / file? what can i do

  • Contains performs MUCH slower with variable vs constant string SQL Server

    - by Greg R
    For some unknown reason I'm running into a problem when passing a variable to a full text search stored procedure performs many times slower than executing the same statement with a constant value. Any idea why and how can that be avoided? This executes very fast: SELECT * FROM table WHERE CONTAINS (comments, '123') This executes very slowly and times out: DECLARE @SearchTerm nvarchar(30) SET @SearchTerm = '123' SET @SearchTerm = '"' + @SearchTerm + '"' SELECT * FROM table WHERE CONTAINS (comments, @SearchTerm) Does this make any sense???
