Bug #77229 [NEW]: Phar::buildFromDirectory() generates tar archives in 'PAX' format

From: michae dot lee at zerustech dot com Operating system: macOS High Sierra 10.13.6 PHP version: Irrelevant Package: PHAR related Bug Type: Bug Bug description:Phar::buildFromDirectory() generates tar archives in 'PAX' format Description: ------------ The Phar::buildFromDirectory() method generates tar archives in PAX format, so different tar archives that contain the same files may have different sha1 checksums. Test script: --------------- <?php // mkdir test && echo 'hello' > test/test.txt $phar = new \PharData('a.tar'); $phar->buildFromDirectory('test'); // sleep for 1 second to produce different atime. sleep(1); $phar = new \PharData('b.tar'); $phar->buildFromDirectory('test'); echo sha1_file('a.tar') . "\n"; echo sha1_file('b.tar') . "\n"; // a.tar and b.tar contain the same files, but have different checksums // Looks like the buildFromDirectory() method generates tar archives // with PAX headers. Calling "tar --format=ustar -cf ..." from command line // resolves this issue. Expected result: ---------------- The sha1 checksums for a.tar and b.tar should be the same. Actual result: -------------- The sha1 checksums for a.tar and b.tar are different. -- Edit bug report at https://bugs.php.net/bug.php?id=77229&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=77229&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=77229&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=77229&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=77229&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=77229&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=77229&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=77229&r=needscript Try newer version: https://bugs.php.net/fix.php?id=77229&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=77229&r=support Expected behavior: https://bugs.php.net/fix.php?id=77229&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=77229&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=77229&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=77229&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=77229&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=77229&r=dst IIS Stability: https://bugs.php.net/fix.php?id=77229&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=77229&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=77229&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=77229&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=77229&r=mysqlcfg
