DEVELOPER INFO
--------------

phpPgAdmin is Free/Open Source software and contributions are welcome from
everyone.

SOURCE REPOSITORY
-----------------

phpPgAdmin uses git for source control management. The phpPgAdmin git repository 
is hosted at github:

https://github.com/phppgadmin/phppgadmin

Our development process is based around Pull Requests. The best way to 
contribute is with the following guidelines:

= Setup =

1. Make your own fork of the phppgadmin repository.

2. Add the source repository as a remote called "upstream":
        git remote add upstream git@github.com:phppgadmin/phppgadmin.git
    or
        git remote add upstream https://github.com/devopsdays/devopsdays-web.git

You only need to create your fork once, as long as you don't delete it.

= Patches =

1. Before starting any new change, it is essential that you rebase your local 
   repository from the upstream. You may think that working from your fork is 
   enough, but sometimes upstream changes will affect your work in ways you 
   may not anticipate, so you'll want to stay current. Issue these commands:

: git checkout master
    : git pull upstream master --rebase

This confirms you are on the master branch locally, and then applies the 
   changes from the upstream to your copy.

2. Create a new local branch for your changes. This helps to keep things tidy!
    : git checkout -b describe_my_fix

3. Make your changes, test them locally (use the Selenium tests), then push 
   that branch up to origin on your fork.

: git push origin describe_my_fix

4. Submit a Pull Request for the branch you just pushed. As a bonus, if you 
   can add either [BUG] or [FEATURE] to the the title according to the purpose
   that will help with patch review. Additionally, please mention the versions
   of PHP and PostgreSQL that you have tested against.

5. While we would like to enhance our automated testing, until that happens, 
   we at least suggest reviewing the Pull Request on the website and verifying
   that your changes will merge cleanly. If not, please address any conflicts.

6. As a reminder, smaller patches are easier to digest and consume. If you mix
   multiple fixes or features into your Pull Requests, it is likely that your 
   submission will not be merged.

7. Please note that submitting code is considered a transfer of copyright to the 
   phpPgAdmin project. phpPgAdmin is made available under the GPL v2 license.

Push access to the main phpPgAdmin git repository can be granted to developers
with a track record of useful contributions to phpPgAdmin at the discretion
of the phpPgAdmin development team. 
                            
TIPS FOR DEVELOPERS
-------------------

When you submit code to phpPgAdmin, we do expect it to adhere to the existing
coding standards in the source.  So, instead of using your personal favourite
code layout style, please format it to look like surrounding code.
In general, we want the code to be portable, standard compliant (e.g. to W3C 
(X)HTML and CSS) and independent of specific configurations of PHP, the web 
server, PostgreSQL or the user browser. We also try to support as many versions
as possible of these applications.

Test your code properly! For example, if you are developing a feature to create
domains, try naming your domain all of the following:

* "
	* '
	* \
	* words with spaces
	* <br><br><br>

Don't forget to make sure your changes still pass the existing Selenium test 
suite. Additionally, you should add or update the test suite as needed to 
cover your new features.

If you are adding a new class function, be sure to use the "clean",
"fieldClean", "arrayClean" and "fieldArrayClean" functions to properly escape
odd characters in user input.  Examine existing functions that do similar
things to yours to get yours right.

When writing data to the display, you should always urlencode() variables in
HREFs and htmlspecialchars() variables in forms.  Rather than use action=""
attributes in HTML form elements use action="thisformname.php".  This
ensures that browsers remove query strings when expanding the given
relative URL into a full URL.

When working on database classes, always schema qualify your SQL where it is
possible with the current schema ($data->_schema) for pg73+ classes. Then don't
forget to write your method for older classes which don't support schemas.

When working with git, always make sure to do a 'git pull' both before you 
start; so you have the latest code to work with; and also again before you 
create your patch; to minimize the chance of having conflicts. If you plan to 
submit your code via github pull requests, we strongly recommend doing your 
work in a feature specific branch. If you want to submit multiple patches, 
they should all live in their own branch. Remember, smaller changes are easier 
to review, approve, and merge.

COMMON VARIABLES
----------------

$data - A data connection to the current or default database.
$misc - Contains miscellaneous functions.  eg. printing headers & footers, etc.
$lang - Global array containing translated strings.  The strings in this array 
        have already been converted to HTML, so you should not 
        htmlspecialchars() them.
$conf - Global array of configuration options.

WORKING WITH RECORDSETS
-----------------------

phpPgAdmin uses the ADODB database library for all its database access.  We have
also written our own wrapper around the ADODB library to make it more object
oriented (ADODB_base.pclass).

This is the general form for looping over a recordset:

$rs = $class->getResults();
if (is_object($rs) && $rs->recordCount() > 0) {
	while (!$rs->EOF) {
		echo $rs->fields['field'];
		$rs->moveNext();
	}
}
else echo "No results.";

UPDATING LANGUAGE FILES FOR THE MONO-LINGUAL
--------------------------------------------

If you need to add or modify language strings for a new feature, the preferred
method is:

* cd into lang/ subdirectory
* modify english.php file only!

If you've done it correctly, when you create your patch, it should only have 
diffs of the lang/english.php file. For more information on how the language 
system works, please see the TRANSLATORS file.

UNDERSTANDING THE WORK/BRANCH/TAG/RELEASE PROCESS
-------------------------------------------------

All new work for phpPgAdmin is done against the git master branch. When we feel
we are ready to do a new release, we create a branch (ex. REL_4-1).  This 
becomes the stable branch for all future 4.1.x releases, and any bugfixes needed
for 4.1 would go in that branch.

When we release a new revision, we tag that at release time (REL_4-1-1), so a 
checkout of any tag should give you the same files that downloading the release
would have given you. As a general rule, we do not introduce new features into 
existing stable branches, only bugfixes and language updates. This means if you 
want to work on new features, you should be working against the git master. 
Eventually we will call for another release, and that will be branched (REL_4-2)
and the cycle will start over.

On occasion we have created out-of-band branches, typically labeled as DEV_foo.
These were used for temporary, concurrent development of large features, and 
should not be used by other developers. When development of those features is 
completed, the branches get merged in as appropriate, so no further development 
should occur on those branches.

GETTING HELP
------------

We prefer communication to happen via Github and Pull Requests. Beyond that, 
some contributors have been known to hang out on the Postgres Slack Team.
