Req #68615 [NEW]: Faster / slimmer alternative to debug_backtrace

From: ianbytchek at gmail dot com Operating system: PHP version: Irrelevant Package: *General Issues Bug Type: Feature/Change Request Bug description:Faster / slimmer alternative to debug_backtrace Description: ------------ debug_backtrace is a really useful and powerful thing, but often its purpose ends with debugging-related tasks. I stumble across use-cases where it can be just as useful, but the performance is dragging it down. One of such use cases is (semi) automatic dependency injection implemented by referencing caller objects. E.g., when a controller implements an InjectionAwareInterface a model instantiated within the call tree can find the closest InjectionAwareInterface and use dependencies from there. Having the ability to quickly and efficiently extract the caller information would allow to produce cleaner and more robust code. Please consider providing the new get_backtrace_objects() function, which would return only an array of caller objects without repetitive duplicates, i.e., when different methods are called from a single class, both get into debug_backtrace with the same object value, with get_backtrace_objects this would be a single entry. I understand the functionality is already present in the debug_backtrace, however using that to get the list of caller objects adds a massive overhead for also generating other debug-related information. Extracting the objects makes it even slower. -- Edit bug report at https://bugs.php.net/bug.php?id=68615&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=68615&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=68615&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=68615&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=68615&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=68615&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=68615&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=68615&r=needscript Try newer version: https://bugs.php.net/fix.php?id=68615&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=68615&r=support Expected behavior: https://bugs.php.net/fix.php?id=68615&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=68615&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=68615&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=68615&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=68615&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=68615&r=dst IIS Stability: https://bugs.php.net/fix.php?id=68615&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=68615&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=68615&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=68615&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=68615&r=mysqlcfg
