Tips and Tricks for committers

This page provides some useful hints how to work with our infrastructure. And they can also make your work a lot easier.

Set svn properties automatically on new Portfiles

In the configuration for your Subversion client, enable automatic property setting and, for all files named Portfile, setting "svn:eol-style" to "native" and "svn:keywords" to "Id". If you are not using Subversion's own svn command-line client, see its documentation. For svn, you can make the appropriate changes by editing ~/.subversion/config as follows:

...

[miscellany]
enable-auto-props = yes

...

[auto-props]
Portfile = svn:eol-style=native;svn:keywords=Id

Apply patches directly from Trac URL

Installation

Add the following functions to your .bashrc in order to apply patches directly from Trac.

function trac-get {
    curl "$1?format=raw" -o $(basename $1)
}

function trac-patch {
    local cmd=""
    while [[ $1 == -* ]]; do
        if [[ "$1" == "--" ]]; then
            break
        fi

        cmd="$cmd $1"
        shift
    done

    if [[ -z $cmd ]]; then
        cmd="-p0"
    fi  

    trac-get $1
    patch $cmd < $(basename $1)
}

Usage

Use like this:

1. Copy the URL to the patch from the Trac ticket page
2. Switch to the ports directory

   $ cd $(port dir foo)
   

3. Apply the patch

   $ trac-patch http://trac.macports.org/attachment/ticket/.../Portfile.diff
   

You can also add options which will get passed through to the patch tool. This is especially useful when the patch needs another prefix level.

$ trac-patch -p1 http://trac.macports.org/attachment/ticket/.../Portfile.diff

If you don't add any option, -p0 is used as a default. This should be the most common case.
