There is very few information on the Internet on how to solve this problem that I'm having, which is the fact that when i try to rename a file it gives me the error "Device or resource busy in".
this is my code:
if ($handler = opendir($thumb_dir)) {
while (false !== ($thumb_name = readdir($handler))) {
$new_thumb_name = str_ireplace("por_eliminar_" . $_POST['id_anuncio'] . "_",$_POST['titulo'] . "_" . $_POST['id_anuncio'] . "_",$thumb_name);
rename($thumb_dir . $thumb_name,$thumb_dir . $new_thumb_name);
}
In wamp I didn't got this error, but I'm getting in hostgator... any ideas on what the problem might be ?

My script was running fine on apache server. But when i migrated to nginx server, i got the error:
PHP message: PHP Warning: Invalid argument supplied for foreach() in
And there is the code:
foreach($this->_uploaded as $name) {
$file = pathinfo($name);
$ad_count = $file['filename'];
$path = '/images/ads/'.$friendly_name.'-black-friday-'.($ad_count).'-' . $this->createRandomString() . '.' . $file['extension'];
if(!copy(__SITE_PATH . "/public/tmp/" . $name, __FRONTEND_PATH . $path)) {
return false;
}
$this->db->query("INSERT INTO stores_ads (stores_id, path, sort) VALUES (".$id.", '".$path."', ".(int)$ad_count.")");
#unlink(__SITE_PATH . "/public/tmp/" . $name);
}
Do you know the reason why? I think it may get the wrong path of the upload folder? Or something wrong with nginx configuration?
This is the full code:
add something like :
if (is_array($this->_uploaded)) {
//add your code
foreach($this->_uploaded as $name) {
$file = pathinfo($name);
# code...
}
}
hope this help :)
I have written a very simple page counter and a logging script that increments a counter stored in a file and logs information about the client's operating system and which browser they use. It's a simple spare time project I've been working on, and as such it is extremely rudimentary, writing the counter and the logged information in a designated folder for each page on the site, in a new file for each day.
The thing is, I recently used blitz.io to test my site, and when I ran a "Rush" of 250 requests per second, the counters and the logs were completely flushed, except for the very last query.
I'm not perfectly sure what happened, but I suspect something along the lines of PHP not properly finishing up the previous query before taking on the next one.
I use file_get_contents()/file_put_contents() for the both of them, instead of file(). Would changing to file() solve the problem?
Here's the counter:
$filename = '.' . $_SERVER['PHP_SELF'];
$counterpath = '/Websites/inc/logs/counters/total/' . getCurrentFileName() . '-counter.txt';
$globalcounter = '/Websites/inc/logs/counters/total/global-counter.txt';
if (file_exists($counterpath)) {
$hit_count = file_get_contents($counterpath);
$hit_count++;
file_put_contents($counterpath,$hit_count);
}
else {
$hit_count = "1";
file_put_contents($counterpath, $hit_count);
}
And here's the logger:
$logdatefolder = '/Websites/inc/logs/ip/' . date('Y-m-d',$_SERVER['REQUEST_TIME_FLOAT']);
$logfile = $logdatefolder . "/" . getCurrentFileName() . '-iplog.html';
$ua = getbrowser();
if (false == (file_exists($logdatefolder))) {
mkdir($logdatefolder);
}
function checkRef() {
if (!isset($_SERVER['HTTP_REFERER'])) {
//If not isset -> set with dummy value
$_SERVER['HTTP_REFERER'] = 'N/A';
}
return $_SERVER['HTTP_REFERER'];
}
/* Main logger */
$logheader = "<!DOCTYPE html><html xmlns=\"http://www.w3.org/1999/xhtml\" lang=\"en-US\"><head><title>" . getCurrentFileName() . " log</title><meta http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\" /></head><body>";
$logentry = date("Y-m-d, H:i:s, O T") . ":" .
"<br />- Requesting: http://giphtbase.org" . $_SERVER['REQUEST_URI'] .
"<br />- Arriving from: " . checkRef() .
"<br />- Browser: " . $ua['browser'] .
"<br />- Full browser name: " . $ua['name'] .
"<br />- Operating system: " . $ua['platform'] .
"<br />- Full user agent: " . $ua['userAgent'] .
"<br />";
$logfooter = "<!-- Bottom --></body></html>";
if (file_exists($logfile)) {
$logPage = file_get_contents($logfile);
$logContents = str_replace("<!-- Bottom --></body></html>","",$logPage);
file_put_contents($logfile, $logContents . $logentry . $logfooter);
}
elseif (false == (file_exists($logfile))) {
file_put_contents($logfile, $logheader . $logentry . $logfooter);
}
You should use the FILE_APPEND flag in your file_put_contents() otherwise you will only ever see the last entry:
file_put_contents($logfile, $logContents . $logentry . $logfooter, FILE_APPEND);
As for the counter, it looks like the file is trying to be written to too many times by different threads, causing it to be inaccessible. You should either use a database, or create a file_lock, or create temporary files and run a cronjob to do the math.
Selenium2, by default, starts firefox with a fresh profile. I like that for a default, but for some good reasons (access to my bookmarks, saved passwords, use my add-ons, etc.) I want to start with my default profile.
There is supposed to be a property controlling this but I think the docs are out of sync with the source, because as far as I can tell webdriver.firefox.bin is the only one that works. E.g. starting selenium with:
java -jar selenium-server-standalone-2.5.0.jar -Dwebdriver.firefox.bin=not-there
works (i.e. it complains). But this has no effect:
java -jar selenium-server-standalone-2.5.0.jar -Dwebdriver.firefox.profile=default
("default" is the name in profiles.ini, but I've also tried with "Profile0" which is the name of the section in profiles.ini).
I'm using PHPWebdriver (which uses JsonWireProtocol) to access:
$webdriver = new WebDriver("localhost", "4444");
$webdriver->connect("firefox");
I tried doing it from the PHP side:
$webdriver->connect("firefox","",array('profile'=>'default') );
or:
$webdriver->connect("firefox","",array('profile'=>'Profile0') );
with no success (firefox starts, but not using my profile).
I also tried the hacker's approach of creating a batch file:
#!/bin/bash
/usr/bin/firefox -P default
And then starting Selenium with:
java -jar selenium-server-standalone-2.5.0.jar -Dwebdriver.firefox.bin="/usr/local/src/selenium/myfirefox"
Firefox starts, but not using by default profile and, worse, everything hangs: selenium does not seem able to communicate with firefox when started this way.
P.S. I saw Selenium - Custom Firefox profile I tried this:
java -jar selenium-server-standalone-2.5.0.jar -firefoxProfileTemplate "not-there"
And it refuses to run! Excited, thinking I might be on to something, I tried:
java -jar selenium-server-standalone-2.5.0.jar -firefoxProfileTemplate /path/to/0abczyxw.default/
This does nothing. I.e. it still starts with a new profile :-(
Simon Stewart answered this on the mailing list for me.
To summarize his reply: you take your firefox profile, zip it up (zip, not tgz), base64-encode it, then send the whole thing as a /session json request (put the base64 string in the firefox_profile key of the Capabilities object).
An example way to do this on Linux:
cd /your/profile
zip -r profile *
base64 profile.zip > profile.zip.b64
And then if you're using PHPWebDriver when connecting do:
$webdriver->connect("firefox", "", array("firefox_profile" => file_get_contents("/your/profile/profile.zip.b64")))
NOTE: It still won't be my real profile, rather a copy of it. So bookmarks won't be remembered, the cache won't be filled, etc.
Here is the Java equivalent. I am sure there is something similar available in php.
ProfilesIni profile = new ProfilesIni();
FirefoxProfile ffprofile = profile.getProfile("default");
WebDriver driver = new FirefoxDriver(ffprofile);
If you want to additonal extensions you can do something like this as well.
ProfilesIni profile = new ProfilesIni();
FirefoxProfile ffprofile = profile.getProfile("default");
ffprofile.addExtension(new File("path/to/my/firebug.xpi"));
WebDriver driver = new FirefoxDriver(ffprofile);
java -jar selenium-server-standalone-2.21.0.jar -Dwebdriver.firefox.profile=default
should work. the bug is fixed.
Just update your selenium-server.
I was curious about this as well and what I got to work was very simple.
I use the command /Applications/Firefox.app/Contents/MacOS/firefox-bin -P to bring up Profile Manager. After I found which profile I needed to use I used the following code to activate the profile browser = Selenium::WebDriver.for :firefox, :profile => "batman".
This pulled all of my bookmarks and plug-ins that were associated with that profile.
Hope this helps.
From my understanding, it is not possible to use the -Dwebdriver.firefox.profile=<name> command line parameter since it will not be taken into account in your use case because of the current code design. Since I faced the same issue and did not want to upload a profile directory every time a new session is created, I've implemented this patch that introduces a new firefox_profile_name parameter that can be used in the JSON capabilities to target a specific Firefox profile on the remote server. Hope this helps.
I did It in Zend like this:
public function indexAction(){
$appdata = 'C:\Users\randomname\AppData\Roaming\Mozilla\Firefox' . "\\";
$temp = 'C:\Temp\\';
$hash = md5(rand(0, 999999999999999999));

}else{
$hash = $this->params['p'];
}
$ini = new Zend_Config_Ini('C:\Users\randomname\AppData\Roaming\Mozilla\Firefox\profiles.ini');
$path = false;
foreach ($ini as $key => $value){
if(isset($value->Name) && $value->Name == $hash){
$path = $value->Path;
break;
}
}
if($path === false){
die('<pre>No profile found with name: ' . $hash);
}
echo "<pre>Profile : $hash \nProfile Path : " . $appdata . "$path \n";
echo "Files: \n";
$filesAndDirs = $this->getAllFiles($appdata . $path);
$files = $filesAndDirs[0];
foreach ($files as $file){
echo " $file\n";
}

foreach ($dirs as $dir){
$zipRet = $zip->addEmptyDir($dir);

$webDriver = new WebDriver("localhost",'4444');
if(!$webDriver->connect("firefox","",array('firefox_profile'=>$zipString))

die('Selenium is not running');
}
}
private function getAllFiles($path,$WithPath = false){
$return = array();
$dirs = array();
if (is_dir($path)) {

The Idea is that you give in the get/post/zend parameters P with the name of the profile if not a random wil be created, and he will zip all the files put it in the temp folder and put it in.
I have a problem with the php_zip.dll's ZipArchive class. I'm using it through the ZipArchiveImproved wrapper class suggested on php.net to avoid the max file-handle issue.
The problem is really simple: 700 files are added properly (jpg image files), and the rest fails. The addFile method returns false.
The PHP version is 5.2.6.
The weird thing is that this actually used to work.
What could be the problem? Can you give me any clues?
Thank you very much in advance!
Edit: sorry, it's not true that I'm not getting any error message (display_errors was switched off in php.ini I didn't notice it before). From the 701. file on, I'm getting the following error message:
Warning: ZipArchive::addFile() [ziparchive.addfile]: Invalid or unitialized Zip object in /.../includes/ZipArchiveImproved.class.php on line 104
Looks like the close() call returns false, but issues no error. Any ideas?
Edit 2: the relevant source:
include_once DIR_INCLUDES . 'ZipArchiveImproved.class.php';
ini_set('max_execution_time', 0);
$filePath = $_SESSION['fqm_archivePath'];
$zip = new ZipArchiveImproved();
if(! $zip->open($filePath, ZipArchive::CREATE))
{
echo '<div class="error">Hiba: a célfájl a(z) "' . $filePath . '" útvonalon nem hozható létre.</div>';
return;
}
echo('Starting (' . count($_POST['files']) . ' files)...<br>');
$addedDirs = array();
foreach($_POST['files'] as $i => $f)
{
$d = getUserNameByPicPath($f);
if(! isset($addedDirs[$d]))
{
$addedDirs[$d] = true;
$zip->addEmptyDir($d);
echo('Added dir "' . $d . '".<br>');
}
$addName = $d . '/' . basename($f);
$r = $zip->addFile($f, $addName);
if(! $r)
{
echo('<font color="Red">[' . ($i + 1) . '] Failed to add file "' . $f . '" as "' . $addName . '".</font><br>');
}
}
$a = $zip->addFromString('test.txt', 'Moooo');
if($a)
{
echo 'Added string successfully.<br>';
}
else
{
echo 'Failed to add string.<br>';
}
$zip->close();
It's probably because of maximal number of open files in your OS (see http://www.cyberciti.biz/faq/linux-increase-the-maximum-number-of-open-files/ for more detailed info; it can by system-wide or just user limit).
Zip keeps every added file open until Zip::close is called.
The solution is to close and reopen archive every X files (256 or 512 should be safe value).
The problem is described here: http://www.php.net/manual/en/function.ziparchive-open.php#88765
Have you tried to specify both flags?
I solved this problem by increasing the ulimit: ulimit -n 8192.
im using the following code;
if( ! file_exists( $path ) ) { die( "'" . $path . "' not vaild path"); }
copy( $path, ltrim($create_folder . ltrim($path, "./"), ".") );
echo "'" . $path. "' => '" . $create_folder . ltrim($path, "./") . "'<br />";
The first if statement returns true yet the copy function returns;
Warning: copy('./files/c7a628cba22e28eb17b5f5c6ae2a266a/0003.css') [function.copy]: failed to open stream: No such file or directory
'./files/c7a628cba22e28eb17b5f5c6ae2a266a/0003.css' => './224efcdebda48350056af291f64a9311/files/8b571e7fbf9bacf4473024b11f78bc0dfiles/c7a628cba22e28eb17b5f5c6ae2a266a/0003.css'
If anyone knows why it would be much appreciated.
You might notice that your second half is missing a slash. As in, one of your path elements is "8b571e7fbf9bacf4473024b11f78bc0dfiles" instead of "8b571e7fbf9bacf4473024b11f78bc0d/files". Try $create_folder . '/' . ltrim($path, "./")
But the real answer is "your file actually does not exist. No, really, PHP is correct". It's just talking about the destination not existing; the source is fine.
