PHP ZipArchive::addGlobe() is slow I can not delete temp directory - php

I have a code which
Generate csv files to temp directory
Call ZipArchive::addGlob()
Then remove temp dir
But it seems the addGlobe() is not enough fast and files are deleted before addGlob() creates the zip file.
Code looks like:
function saveCsvDaysDataZip($campaign_id)
{
$tempDirName = CampaignsDeviceDays::CSV_REPORTS_DIR . '/' . $campaign_id . '/temp';
$zip = new ZipArchive();
$zip->open($tempDirName . 'reports.zip', ZipArchive::CREATE | ZipArchive::OVERWRITE);
$addGlob = $zip->addGlob("$tempDirName/*", GLOB_BRACE, ['remove_all_path' => TRUE]);
if( $addGlob === false ) throw new \Exception("CampaignsDeviceDays::saveCsvDaysDataZip() error: \$zip->addGlobe() failed. " . $this->zipArchive->getStatusString() );
}
public function removeCsvExportsDir($campaign_id)
{
$dirName = self::CSV_REPORTS_DIR . '/' . $campaign_id . '/temp';
FileSystem::delete($dirName);
}
$saveCsvDaysDataZip($campaign_id);
$removeCsvExportsDir($campaign_id);
Is it possible that removeCsvExportsDir($campaign_id) is called before addGlob() is done?

Your function had no call to ZipArchive::close - which I guess PHP will then take as "permission" to continue populating the ZIP archive in the background, and return before that process is actually finished.

'ZipArchive::close()' not working on web server

I am building a folder with files in it. At the end, I want to Zip this folder. On my local machine using Homestead, everything works correctly.
However, on my web server I am getting the error:
ZipArchive::close(): Can't remove file: No such file or directory
Why? The folder is filled with all files...
My code:
$zip_file = storage_path('app\\takeouts\\takeout_' . $this->dataExports->uuid . '.zip');
$this->zip = new \ZipArchive();
$this->zip->open($zip_file, \ZipArchive::CREATE | \ZipArchive::OVERWRITE);
$this->addAllFilesToZipArchive($this->folder_name);
$this->zip->close();
Storage::deleteDirectory($this->folder_name);
private function addAllFilesToZipArchive($dir)
{
$dirs = Storage::directories($dir);
$files = Storage::files($dir);
foreach ($files as $file)
{
if(Storage::exists(storage_path("app\\" . $file))) {
$this->zip->addFile(storage_path("app\\" . $file), str_replace($this->folder_name,"","/" . $file));
}
}
foreach ($dirs as $dir2) {
$this->addAllFilesToZipArchive($dir2);
}
}
It may seem a little obvious to some but it was an oversight on my behalf.
ll the close() function.
If the files added to the object aren't available at save time the zip file will not be created.

PHP - ZipArchive() permission issues with clean up

I keep having - I think permission issues - with unzipping a file (this part goes OK) and moving content to write folder.
I am running simple code:
$zip = new ZipArchive( );
$x = $zip->open( $file );
if ( $x === true ) {
$zip->extractTo( $target );
$zip->close( );
unlink( $file );
rmove( __DIR__ . '/' . $target . '/dist', __DIR__ );
} else {
die( "There was a problem. Please try again!" );
}
where rmove() is a simple recursive function that iterates thru content and applies rename() to each file.
Problem is that unzipping goes well, files are copied, but not moved - delete from a temporary folder. I read so far that could be caused by not having a write permission to unzipped files at the time of renaming.
How to control those permissions at the time of unzipping?
Update: content of rmove():
function rmove( $src, $dest ) {
// If source is not a directory stop processing
if ( ! is_dir( $src ) ) return false;
// If the destination directory does not exist create it
if ( ! is_dir( $dest ) ) {
if ( ! mkdir( $dest ) ) {
// If the destination directory could not be created stop processing
return false;
}
}
// Open the source directory to read in files
$i = new DirectoryIterator( $src );
foreach( $i as $f ) {
if ( $f->isFile( ) ) {
echo $f->getRealPath( ) . '<br/>';
rename( $f->getRealPath( ), "$dest/" . $f->getFilename( ) );
} else if ( ! $f->isDot( ) && $f->isDir( ) ) {
rmove( $f->getRealPath( ), "$dest/$f" );
unlink( $f->getRealPath( ) );
}
}
unlink( $src );
}
As far as I'm aware ZipArchive::extractTo doesn't set any special write/delete permissions, so you should have full access to the extracted files.
The issue with your code is the rmove function. You're trying to remove directories with unlink, but unlink removes files. You should use rmdir to remove directories.
If we fix that issue, your rmove function works fine.
function rmove($src, $dest) {
// If source is not a directory stop processing
if (!is_dir($src)) {
return false;
}
// If the destination directory does not exist create it
if (!is_dir($dest) && !mkdir($dest)) {
return false;
}
// Open the source directory to read in files
$contents = new DirectoryIterator($src);
foreach ($contents as $f) {
if ($f->isFile()) {
echo $f->getRealPath() . '<br/>';
rename($f->getRealPath(), "$dest/" . $f->getFilename());
} else if (!$f->isDot() && $f->isDir()) {
rmove($f->getRealPath(), "$dest/$f");
}
}
rmdir($src);
}
You don't have to remove every subfolder in the loop, the rmdir at the end will remove all folders, since this is a recursive function.
If you still can't remove the contents of the folder, then you may not have sufficient permissions. I don't think that's very likely, but in that case you could try chmod.
I just wonder about the $target.'/dist' directory. I assume that the 'dist' directory is coming from the archive. Having pointed out that I can see the 'rmove' function is prone to copy a file to a destination directory before it is created. Your code assumes that the directory will supersede the files in the iterator. If the file path supersedes the directory the destination directory won't exist to copy the file.
I would suggest you an alternative function to your custom written recursive 'rmove' function, which is the RecursiveDirectoryIterator.
http://php.net/manual/en/class.recursivedirectoryiterator.php
Let me simplify your code with RecursiveDirectoryIterator as follows
$directory = new \RecursiveDirectoryIterator( __DIR__ . '/' . $target . '/dist', RecursiveDirectoryIterator::SKIP_DOTS);
$iterator = new \RecursiveIteratorIterator($directory);
foreach ($iterator as $f) {
if($f->isFile()){
if(!empty($iterator->getSubpath()))
#mkdir(__DIR__."/" . $iterator->getSubpath(),0755,true);
rename($f->getPathname(), __DIR__."/" . $iterator->getSubPathName());
}
}
Please check to see whether you still get the permission error.

How to Display CSV file content in Controller as an Array?

I am trying to display CSV data to array or something as an output using Zend Framework 2
I have created "hello world" module and the controller calls works fine.
CSV File location is data/csv/Foo.csv
Below is my controller:
public function indexAction()
{
$filename = 'data/csv/Foo.csv';
$useFirstRecordAsHeader = true;
$delimiter = ',';
$enclosure = '"';
$escape = '\\';
$this->file = new SplFileObject($filename);
$this->file->setFlags(SplFileObject::READ_CSV | SplFileObject::READ_AHEAD | SplFileObject::SKIP_EMPTY | SplFileObject::DROP_NEW_LINE);
$this->file->setCsvControl($delimiter, $enclosure, $escape);
$this->useFirstRecordAsHeader = $useFirstRecordAsHeader;
return $this;
}
But right now I am getting the error:
SplFileObject::__construct(csv/Foo.csv): failed to open stream: No
such file or directory
My CSV file is in the same folder controller/csv/Foo.csv
How to read a CSV file content and display as output array or any other format? I want to do it using Zend Framework 2 only.
You are trying to open $this->file = new SplFileObject('csv/Foo.csv');, since you are using a relative path, on execution time that wont resolve to the folder where your controller is at (it will probably resolve to [yourprojectroot]/csv/Foo.csv).
If you really wanted to store this csv in controller/csv, you should use something like:
$this->file = new SplFileObject(dirname(__FILE__) . '/csv/Foo.csv');
But, saving that csv there is bad for a several reasons. First you'd need to grant write permission to your webserver to be able to write in that directory, and you'd be fundamentally messing up with your data/code structure (data and code shouldn't reside together, but in easily separated silos).
Better, create a folder "data" and and another folder "csv" in your projects directory, give your webserver permission to write there (chmod || chown, other methods), and do something like:
$file = 'data'. DIRECTORY_SEPARATOR . 'csv' . DIRECTORY_SEPARATOR . 'Foo.csv' ;
$this->file = new SplFileObject($file );
Besides that, I'm not sure what you are returning actually makes sense. Try something like:
public function indexAction()
{
$filename = 'data' . DIRECTORY_SEPARATOR . 'csv' . DIRECTORY_SEPARATOR . 'Foo.csv';;
$this->file = new SplFileObject($filename);
$this->file->setFlags(SplFileObject::READ_CSV | SplFileObject::READ_AHEAD | SplFileObject::SKIP_EMPTY | SplFileObject::DROP_NEW_LINE);
$this->file->setCsvControl(',', '""', '\\');
$this->useFirstRecordAsHeader = true;
$response = $this->getResponse();
$headers = $response->getHeaders();
$headers->addHeaderLine('Content-Type', 'text/csv');
$contents = $this->file->fread($this->file->getSize());
$response->setContent($contents);
return $response;
}
You should not put your csv directory in the Controller directory, as it is not a controller. It's against the MVC architecture. The good practise is to put data in the data directory, under your root directory, at the same level as your module directory.
So assuming you have it on this data directory, you can simply write:
$this->file = new SplFileObject('data/csv/Foo.csv');
or better (for portability):
$filename = 'data'. DIRECTORY_SEPARATOR . 'csv' . DIRECTORY_SEPARATOR . 'Foo.csv' ;
$this->file = new SplFileObject($filename );

Losing variable value when trying to copy file using mailReader.php

I'm using the mailReader script found here: https://github.com/stuporglue/mailreader
I am trying to copy the file(s) after upload to another folder.
The file(s) upload correctly to the folder where the script resides.
When I try to run a copy command, the filename variable is empty.
Here is the portion of the code I am working with: The last three lines are what I added.
private function saveFile($filename,$contents,$mimeType = 'unknown'){
$filename = preg_replace('/[^a-zA-Z0-9_-]/','_',$filename);
$unlocked_and_unique = FALSE;
while(!$unlocked_and_unique){
// Find unique
$name = time() . "_" . $filename;
$name = substr_replace($name,".pdf",-4); // added 1-19-2016
while(file_exists($this->save_directory . $name)) {
$name = time() . "_" . $filename;
$name = substr_replace($name,".pdf",-4);
}
// Attempt to lock
$outfile = fopen($this->save_directory.$name,'w');
if(flock($outfile,LOCK_EX)){
$unlocked_and_unique = TRUE;
}else{
flock($outfile,LOCK_UN);
fclose($outfile);
}
}
fwrite($outfile,$contents);
fclose($outfile);
if (copy($this->save_directory.$name, "/attachments/" . TRANS_ID . "/". $name)) {
unlink( $this->save_directory.$name );
}
I receive confirmation by email that the file(s) are uploaded, then another email with the error message.
Warning: copy(/attachments/W7652222-546/1453406138_residential-print_from_td.pdf): failed to open stream: No such file or directory in /home/myhost/public_html/mailreader/mailReader.php on line 224
224 being the line number of my added code.
The source filename is missing from in front of /attachments...
Anyone have any thoughts?
$name is defined in the while loop and may not be accessible on the upper scopes my suggestion is to change your code to this:
private function saveFile($filename,$contents,$mimeType = 'unknown'){
$filename = preg_replace('/[^a-zA-Z0-9_-]/','_',$filename);
$unlocked_and_unique = FALSE;
$name = '';
while(!$unlocked_and_unique){
// Find unique
$name = time() . "_" . $filename;
$name = substr_replace($name,".pdf",-4); // added 1-19-2016
while(file_exists($this->save_directory . $name)) {
$name = time() . "_" . $filename;
$name = substr_replace($name,".pdf",-4);
}
// Attempt to lock
$outfile = fopen($this->save_directory.$name,'w');
if(flock($outfile,LOCK_EX)){
$unlocked_and_unique = TRUE;
}else{
flock($outfile,LOCK_UN);
fclose($outfile);
}
}
fwrite($outfile,$contents);
fclose($outfile);
if (copy($this->save_directory.$name, "/attachments/" . TRANS_ID . "/". $name)) {
unlink( $this->save_directory.$name );
}
I hope this solves your problem
I ended up defining a constant of email_id in the private function saveToDb, then running a script after everything else is finished to query the table using the email_id and looping through the records moving the files.

Assetic is generating multiple files with same content

I have a class that uses Assetic to generate some css files to disk. I'll jump right into the code.
In my layout header, I'm doing something like this:
$assetify = new Assetify();
$assetify->setDebug(true);
$assetify->setAssetDirectory(BASE_DIR . '/public/assets');
$assetify->setOutputDirectory(BASE_DIR . '/public/assets/generated');
$assetify
->addStylesheet('/assets/css/bootstrap-2.3.2.css')
->addStylesheet('/assets/css/select2-3.4.3.css')
->addStylesheet('/assets/css/main.css');
echo $assetify->dump();
My "Assetify" class runs this through Assetic. I'll paste what I hope are only the relevant portions from the dump() function:
// The Asset Factory allows us to not have to do all the hard work ourselves.
$factory = new AssetFactory($this->assetDirectory, $this->debug);
$factory->setDefaultOutput('/generated/*.css');
// The Filter Manager allows us to organize filters for the asset handling.
// For other filters, see: https://github.com/kriswallsmith/assetic
$fm = new FilterManager();
$fm->set('yui_css', new Yui\CssCompressorFilter('/usr/local/bin/yuicompressor-2.4.7.jar'));
$fm->set('yui_js', new Yui\JsCompressorFilter('/usr/local/bin/yuicompressor-2.4.7.jar'));
$factory->setFilterManager($fm);
// The Asset Manager allows us to keep our assets organized.
$am = new AssetManager();
$factory->setAssetManager($am);
// The cache-busting worker prefixes every css with what amounts to a version number.
$factory->addWorker(new CacheBustingWorker());
$assetCollection = array();
foreach ($assetGroups as $assetGroup) {
foreach ($assetGroup as $media => $items) {
$fileCollection = array();
foreach ($items as $item) {
// Add this asset to the asset collection.
$fileCollection[] = new FileAsset($item);
}
$assetCollection[] = new AssetCollection($fileCollection);
}
}
$assetCollection = new AssetCollection($assetCollection);
$am->set('base_css', $assetCollection);
// Generate the required assets. Prefixing a filter name with a question mark
// will cause that filter to be omitted in debug mode.
$asset = $factory->createAsset(
array('#base_css'),
array('?yui_css')
);
// Configure an internal file system cache so we don't regenerate this file on every load.
$cache = new AssetCache(
$asset,
new FilesystemCache($this->outputDirectory)
);
// And generate static versions of the files on disk.
$writer = new AssetWriter($this->assetDirectory);
$writer->writeAsset($cache);
This generates two different files, 87229eb-f47a352.css and a37c1589762f39aee5bd24e9405dbdf9. The contents of the files are exactly the same. The 87229eb-f47a352.css file seems to get generated every single time, and the other file is not regenerated unless the contents of the files change (this is what I would like). If I comment out the $writer->writeAsset($cache), no files are written to disk.
What obvious configuration am I missing? I appreciate the help, thank you.
I was able to roughly replicate your code and got the same results.
I was trying to get the same results as what I think you require but ended up writing my own code to cache and serve static files.
It's not complete by any means but it is working. It has the following features:
You can choose to cache files for different pages if you specify $filename
You can choose to create versions of your released files or delete previous versions
A cached file will be generated to your target folder only if changes have made to a source file
You just need to put the code in to a class or function and return the url to serve.
Hope it helps :)
