Summary

GT.M is the database of record and NoSQL
application development & deployment platform at some of the
largest real-time core-banking and electronic health record systems
deployments around the world. With its source code available under a
free / open source software (FOSS) license, GT.M has been downloaded
over 135,000 times from its primary site, is bundled with selected
applications, and can be installed on contemporary Debian/Ubuntu
systems with sudo
apt-get install fis-gtm.

Although GT.M has been free to hack¹
for the entire twenty-first century, its complexity, which arises
from its breadth of functionality, as well as its uncompromising
robustness, performance and security, is an obstacle. The workshop
leader, with decades of experience developing GT.M, gets you started.

Hacking GT.M
is a very hands-on course. The emphasis is on learning by doing
under the guidance of a workshop leader, rather than learning by
being taught by an instructor.

Target Audience

Experienced C programmers will benefit from the Hacking GT.M
workshop. An understanding of common tools such as makefiles, C
compilers, and debuggers is required; knowledge of specific tools
used to develop GT.M cmake, gcc, gdb, ld would be helpful.
Expertise in shell scripting is required; knowledge of the POSIX API
would be helpful. While specific experience with GT.M is not
required, exposure to GT.M would be helpful to understand why things
are the way they are.

Topics

The workshop leader will lead discussions on the
following topics.

• The directory structure of a
  GT.M source code distribution.

• Compiling GT.M, including
  needed tools.

• The internal structure and
  organization of GT.M (API layers and relationships).

• Working with the FIS GT.M
  team, including: creating specifications and release notes;
  regression testing and tests suitable for incorporation into the
  GT.M automated regression test suite; submitting your changes;
  coding standards; and more.
