How to have write access to Subversion repository?

• ask it with the contact form
• if project administrators agree with your request, we will ask you to provide a “htpasswd string” that can be generated on this page (select the MD5 algorithm)
• configure tools (Linux, Windows XP)

You'll find documentation on internet. External links:

• Subversion official website

Before going any further, take a look at Branch and releases to understand what we mean when talking about trunk, branches and releases.

# working on trunk
$ svn checkout http://piwigo.org/svn/trunk
$ cd trunk
$ vi feed.php
$ vi notification.php
$ svn diff feed.php notification.php
$ svn commit -m "add new informations in RSS notification feed" feed.php notification.php
 
# working on branch 1.5
$ svn checkout http://piwigo.org/svn/branches/1.5
$ cd 1.5
$ vi include/functions_html.inc.php
$ svn commit -m "bug 256 fixed: wrong tags for HTML menus" include/functions_html.inc.php

• must be written in english
• each line should not exceed 80 columns

Each commit log have a distinct paragraph for each modification done. Two paragraphs are separaterd with an empty line. Each kind of modification must be easy to understand just by reading the log.

The following example shows a commit log with several kind of modification. Of course, you wont ever have as many modification in a single commit, it's just an example. Thanks to be rigorous enough for “bug XXX fixed:”, “merge -r?:? from ? into ? (bug ? fixed)”, “feature XXX added:”.

bug 205 fixed: advise to perform maintenance actions at the end of upgrade
process.

feature 147 added: add a menu to manage manually create_listing_file.php
on remote sites

new: "quick start" section in Administration>General>Instructions

improvement: long localized messages are in HTML files instead of $lang
array. This is the case of admin/help and about pages.

deletion: of unused functions (ts_to_mysqldt, is_image, TN_exists,
check_date_format, date_convert, get_category_directories,
get_used_metadata_list, array_remove, pwg_write_debug,
get_group_restrictions, get_all_group_restrictions, is_group_allowed,
style_select, deprecated_getAttribute).

When a commit is a merge from a branch to another, give details about the merge and what was merge (copy log from original commit).

merge -c2811 from branch 2.0 to trunk
