v61 v62 11 11 Applications should be done online, on the [http://code.google.com/soc/2008/ Google SoC website]. You will find more information on their page on [http://groups.google.com/group/google-summer-of-code-announce/web/guide-to-the-gsoc-web-app-for-student-applicants "Student Applications"]. Initial student applications [http://code.google.com/support/bin/answer.py?answer=60325&topic=10729 "must be"] submitted by 5 pm PDT, March 26th, 2008. 12 12 13 There are several things to consider. We are willing to support and mentor students who want to gain an experience by working on the macports project. We have many ideas for potential internship subjects, yet we are open to anything that is both interesting and relevant to the MacPorts project. Motivated students do not necessarily need to know Tcl language beforehand, especially if they already know several script languages such as python, rubyor perl.13 There are several things to consider.

We now need a system to re-use port information about one python port to create Ports for Python 2.4 AND Python 2.5 (and also for the upcoming 2.6 and 3.0 release). 47 48 This though has to be made modular, so we can just re-use the description, etc. (if different versions of one module are required for different Python versions) or just re-use the whole information (checksums, etc.). … … 61 62 Classification: challenging task[[BR]] 62 63 Programming languages: Tcl and C[[BR]] 63 Potential mentor: rhwood 64 Potential mentor: rhwood, jmpp 64 65 65 66 ==== Task 4: Binaries ==== … … 69 70 Classification: relatively challenging to challenging task[[BR]] 70 71 Programming language: Tcl[[BR]] 71 Potential mentors: wms 72 Potential mentors: wms, jmpp 72 73 73 74 ==== Task 5: Graphical user interface ==== … … 80 81 ==== Task 6: Images (Pkgview, depot-to-depot dependencies) ==== 81 82 82 MacPorts implements what we call the Image mode where software are stored in a depot (e.g. /opt/local/var/db/dports/software/gawk/3.1.5_2/opt/local/bin/gawk). For the moment, this functions like an archive and files are hardlinked to their active location (/opt/local/bin/gawk). If port A depends on dynamic library B.dylib from port B, it actually links to /opt/local/lib/B.dylib. The idea of this task is to figure out a way for port A to be linked to the library in the depot and to work even if port B is not active. That is to say that if port foo depends on version 1.2.3 of port bar, it should be compiled and linked in such a way that it's wired to the depot location of bar, not the "activated" location. That will finally fix the fragility problem where deactivating port bar vers n-1 in order to install port bar vers n (because other things depend on n) won't also require breaking everything that relies on n-1. This mechanism also has additional advantages such as limiting the unavailability time to a minimum, especially when upgrading libraries every other package depends on (such as gettext).83 MacPorts implements what we call the Image mode where software are stored in a depot (e.g. `/opt/local/var/db/dports/software/gawk/3.1.5_2/opt/local/bin/gawk`).

When a a build is attempted but an error keeps it from completing, there's no way to track the problem other than the build progress that was output to the terminal, if verbose mode was requested in the first place. Otherwise, the build environment has to be pruned and the build attempted once again to even get a look at the precise error message. This is particularly problematic when automated builds are attempted, since there's usually no one around to have a look at the failure spew. An infrastructure to remedy this situation and endow MacPorts with a rich set of logging capabilities has to be developed to open up the door to true automated build runs of large sets of ports and thus to packaging of binaries, since with logging we'd have a fully reliable way of catching, reporting and processing of all sorts of fetch/configure/build/destroot/install/etc errors, possibly through the interaction with a server side application like MPWA that could consume these logs (read below). A more detailed draft of this task can be found on the LoggingProposal page. 130 131 Classification: medium task to relatively challenging[[BR]] 132 Prohramming languages: xml or yaml or html, C, Tcl, PHP or RoR[[BR]] 133 Potential mentor: jmpp, wms 134 135 ==== Task 13: MacPorts Web Application ==== 127 136 128 137 A very good start has been made on a Web Application for MacPorts to serve as a basis for easier user submission and maintenance of ports, not to mention monitoring of port build status, browsing of ports, etc. This work is known as MPWA and is written in Ruby on Rails. This task is to complete the work on MPWA so that it is usable for day to day usage by the MacPorts community. Work is needed on user credentials and authentication, port dependency integration, port submission and tracking, etc. This is a very exciting project and can help MacPorts scale to support a larger community. 129 138 130 Read more about the [ http://svn.macports.org/repository/macports/users/jberry/mpwa/doc/ MPWA design and model].139 Read more about the [source:users/jberry/mpwa/doc/ MPWA design and model]. 131 140 132 141 Classification: moderate, with good follow through vision, and architecture required[[BR]] … … 144 153 145 154 ==== Task A2: Documentation and Website ==== 146 * Improve macports documentation147 * Improve macports website155 * Improve MacPorts documentation 156 * Improve MacPorts website 148 157 * Custom Trac plugins 149 158
