You should try to solve before a test, you can find it in the wiki page
related to the project
<https://trac.osgeo.org/postgis/wiki/GoogleSummerCode2021>. It mainly is:

   1. git clone PostGIS code from one of Git repos
   <https://trac.osgeo.org/postgis/wiki/CodeMirrors>
   2. git clone code from PostgreSQL git repo (master branch) -
   3. Compile both and install PostGIS 3.2 (master branch) extension into
   PostgreSQL 14 dev database
   4. Setup a public fork of PostGIS repo for your work

You should provide a script which includes the command you used to set up
the dev database, and a link to the public fork you created, with the git
commands
you used to be properly rebased on the official mirror.

Also, you have officially to apply through the GSoC website - this email is
not enough. You have to submit a PDF document with the following paragraph
filled:

1. Contact Details

2. Title

3. Brief Project Description

4. State of the Project Before GSoC

5. Benefits to Community

6. Deliverables

7. Timeline
     - Community Bonding Period (May 17, 2021 - June 7, 2021) : provide
info about your plan to get ready to
       work on the topic.
     - First coding phase (June 7 - July 11) : Detailed roadmap of the work
on a weekly base (ex. week June 7 - June 11
       I'll define this function for this purpose). There's a first
evaluation at the end of this phase of the partial work.
     - Second phase (July 12 - August 15) : there's a final evaluation. We
expect you will be able to provide the support
       functions to improve GiST build for at least 2D geoms, with working
regression tests. In any case, something that can
       be merged on a temporary development branch in a repo which I can
use to finalise the PR to the main one.

8. Do you understand this is a serious commitment, equivalent to a
full-time paid summer internship or summer job?

9. Do you have any known time conflicts during the official coding period?

10. Studies:
    - What is your school and degree?
    - Would your application contribute to your ongoing studies/degree? If
so, how?

11. Programming and GIS
    - Computing Experience (if any)
    - GIS programming and other software programming (if any)
    - Briefly mention and link to former open-source contributions (if any)

12. GSoC Participation
    - Have you participated in GSoC before?
    - Have you applied but were not selected? When?
    - Have you submitted/will you submit another proposal for this year's
GSoC to a different org? Which one?

13. Requirements: did you cover them?
    - git clone PostGIS code from one of Git repos
    - git clone code from PostgreSQL git repo (master branch)
    - Compile both and install PostGIS 3.2 (master branch) extension into
PostgreSQL 14 (master branch) dev database
    - Setup a public fork of PostGIS repo for your work (properly rebased
on the official one)

14. Bit more details about the theory behind your implementation

15. References linked to the previous point 14.

16. Attach your resume

This has to be done by *April 13th*. It would be good to have a preliminary
call in order to present the project so you can fill it in the propest way.

The two mentors for this project are me and Regina Obe.

Regards,
Giuseppe.
