Submitting Patch for PHP ======================== This document describes how to submit a patch for PHP. Since you are reading this document, you are willing to submit a patch for PHP. Please keep reading! Submitting a patch for PHP is easy. The hard part is making it acceptable for inclusion into our repository. :-) How to create patch? -------------------- We are working with CVS. You need to get CVS source to create a patch that we accept. Visit http://www.php.net/anoncvs.php to get CVS source. You can check out older versions, but make sure you get the default branch (i.e. Do not use -r option when you check out the CVS source) Read CODING_STANDARDS file before you start working. Now you are ready to create a patch. Modify source to fix a bug in PHP or add a new feature to PHP. After you finished editing, please test your patch. Read README.TESTING for testing. After you finish testing your patch, take diff file using "cvs diff > your.patch" command. Read README.TESTING for submitting a test script for your patch. This is not strictly required, but it is preferred to submit a test script along with your patch. Making new test script is very easy. It also helps us to understand what you have been fixed or added to PHP. Tips for creating patch ----------------------- If you would like to fix multiple bugs. It is easier for us if you could create 1 patch for 1 bug, but this is not strictly required. Note though that you might get little response, if your patch is too hard to review. If you would like change/add many lines, it is better to ask module maintainer and/or internals@lists.php.net, or pear-dev@lists.php.net if you are patching PEAR. Official module maintainers can be found in EXTENSIONS file in PHP source. If you are new to CVS (Concurrent Versions System), visit http://cvshome.org/ for details. Recommended CVS client settings for creating patch file ------------------------------------------------------ Recommended ~/.cvsrc file setting is: ------ cvs -z3 update -d -P checkout -P diff -u ------ diff -u means: -u Use the unified output format. With this CVS setting, you don't have to worry about adding/deleting newlines and spaces. Check list for submitting patch ------------------------------- - Did you run "make test" to check if your patch didn't break other features? - Did you compile PHP with --enable-debug and check the PHP and web server error logs when you test your patch? - Did you build PHP for multi-threaded web servers. (Optional) - Did you create test script for "make test"? (Recommended) - Did you check your patch is unified format and it does not contain white space changes? (If you are not using recommended cvs setting) - Did you update CVS source before you take final patch? - Did you read the patch again? Where to send your patch? ------------------------- If you are patching C source, send the patch to internals@lists.php.net. If you are patching a module, you should also send the patch to the maintainer. Official module maintainers are listed in EXTENSION file in source. If you are patching PEAR, send the patch to pear-dev@lists.php.net. Please add the prefix "[PATCH]" to your email subject and make sure to include the patch as a MIME attachment even if it is short. NOTE: only MIME attachments of type 'text/*' are accepted. The easiest way to accomplish this, is to make the extension '.txt'. Test scripts should be included in the same email. Explain what has been fixed/added/changed by your patch. Finally, add the bug Id(s) which can be closed by your patch, if any. What happens after you submit your patch ---------------------------------------- If your patch is easy to review and has obviously no side-effects, it might take up to a few hours until someone commits it. Because this is a volunteer-driven effort, more complex patches will require more patience on your side. If you did not receive any feedback in a few days, please consider resubmitting the description of your patch, along-side with these questions: - Is my patch too hard to review? Because of which factors? - Should I split it up in multiple parts? - Are there any unwanted whitespace changes? What happens when your patch is applied? ---------------------------------------- Your name will be included together with your email address in the CVS commit log. If your patch affects end-users, a brief description and your name might be added to the NEWS file. Thank you for submitting patch for PHP!
