#41456 [Asn]: Cannot decompress newly added files

ID: 41456 User updated by: sander dot marechal at tribal dot nl Reported By: sander dot marechal at tribal dot nl Status: Assigned Bug Type: Feature/Change Request Operating System: Linux PHP Version: 5.2.2 Assigned To: pajoye New Comment: In that case, can't ZipArchive detect I'm trying to read a file that has pending operations and read from it's internal cache instead of from the file? Alternatively, would it be possible to add a ZipArchive::flush() method which applies all pending operations, so I can safely read from it afterwards? My PHP application processes a lot of ODF files, which are essentially ZIP containers. So, I pass around a lot of ZipArchive instances by reference. I usually can't close and reopen the file because I don't have the filename around but just the ZipArchive instance. Previous Comments: ------------------------------------------------------------------------ [2007-05-23 22:14:53] pajoye@php.net All operations (delete, comments, etc.) are applied to the zip file on close, not only the added files. It allows undo, sanity checks as well as a couple of improvements in the final zip files. "// Please make sure a dummy test.zip exist before running this code" Use the creation mode :) ------------------------------------------------------------------------ [2007-05-21 12:49:28] sander dot marechal at tribal dot nl Description: ------------ When I add or update a file in the zip archive, I cannot read the new file without closing and reopening the archive first. If this turns out to be a limitation in zlib then I suggest that a ZipArchive::flush() method of some sorts is added which can be called between a write and a read to produce the expected result. Reproduce code: --------------- #!/usr/bin/php -q <?php // Please make sure a dummy test.zip exist before running this code $zip = new ZipArchive(); $zip->open('test.zip'); $zip->addFromString('test.txt', 'some text'); echo "Before: " . $zip->getFromName('test.txt') . "\n"; $zip->close(); $zip->open('test.zip'); echo "After: " . $zip->getFromName('test.txt') . "\n"; ?> Expected result: ---------------- Both the 'before' and 'after' should output 'some text'. Actual result: -------------- 'before' is empty. Only 'after' shows 'some text'. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=41456&edit=1
