Exiv2

To be discussed on May 5 and 6 at the "Exiv2 Developer's Meeting" in England.

Version 0.27 Specification¶

This project is mostly security fixes.
There are very significant improvements in the build and test architecture.
The project code is on GitHub. https://github.com/Exiv2/exiv2/projects

Backlog¶

1) Why did the code-size spike from 100k to 120k in July 2017? Closed
OpenHub mystery. May 2017: 113961 April 2017: 121196
~/gnu/github/exiv2/exiv2 $ git status | grep branch ; finder "*pp | xargs wc | tail -1
 
2) What's to be done about the duplicated code in tags.cpp and tags_int.cpp?
3) Why did we migrate canonmn.cpp to canonmn_int.cpp?
4) Unit tests discussion
5) Using safe_op.hpp in elderly versions of MSVC (such as 2005)
6) Remove unwanted test/data files from the repos (eg test/data/bugfixes-test.out)
7) Announce that we plan to deprecate the VIDEO and EPS code in v0.28
8) Remove 'using namespace' in all code.
9) Licensing
10) Binary Output
11) Throwing exceptions from BasicIO::read()
12) Why was printStructure() added? (#1245)
13) Project Tool Discussion (Redmine, GitHub, CMake, BuildServer) https://github.com/Exiv2/exiv2/issues/101
 
Before the meeting, I'll review 0.27 open/closed bugs. For sure there will be other matters to discuss.

Google Summer of Code (GSoC)¶

Google sponsor students to work on approved open-source projects for 12 weeks during the summer vacation. I would like to recruit two GSoC students to work on the raw and mobile tasks. I'd like students to work on those tasks for the following reasons:

1) The projects are well defined and isolated.
2) Mentoring/supervision demands should be modest.
3) No complex dependencies.
4) Allows me to have sufficient time to support users.
