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.
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.
If you would like change/add many lines, it is better to ask module
maintainer and/or php-dev@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 -b -w -B
------
diff -u -b -w -B means:
-b Ignore changes in amount of white space.
-B Ignore changes that just insert or delete blank lines.
-u Use the unified output format.
-w Ignore white space when comparing lines.
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 php/webserver
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 php-dev@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 pachting PEAR, send the patch to pear-dev@lists.php.net.
Make sure you add "[PATCH]" prefix to mail subject. Please make sure
attach the patch file even if the patch is really short one. If you
create a test script for your patch, attach it to the same mail.
Finally, explain what has been fixed/added/changed by your patch.
If you know bug ID that can be closed by your patch, please note the
bug ID number also.
How long it will take to get response?
--------------------------------------
Since we are volunteers, it may take more than a few days to get
response. If you didn't get any response in a few days, please let us
know you have been submitted the patch, but you didn't get any
response.
What happens when your patch is applied?
----------------------------------------
When your patch is applied, it will be noted that the patch is
submitted by you. You may see your email address in ChangeLog file. If
your patch is important to be noted in NEWS file, your patch
description and email address will be noted.
If you would not like to be noted in ChangeLog and NEWS file, please
let us know when you submit your patch.
Thank you for submitting patch for PHP!
