Notes on Preparing a GDAL Source Release
========================================
Prerequisites:
1) Check that the release is ready to go as far as ABI (binary compatibility)
is concerned. This can be checked by comparing the installed headers of the
candidate release with the installed headers of the previous release
(diff -ur $(OLD_INSTALL_DIR)/include $(NEW_INSTALL_DIR)/include). The API
is defined as all functions and classes exported by the CPL_DLL keyword.
- For major and minor releases, there must be no function signature change
for the C API. Only new functions are allowed.
- For major releases, the allowed changes in C++ API should (or must?) be
such that user calling C++ code can still compile against new headers
without modification (existing methods can become virtual, default
arguments can be added, new methods or members can be added)
- For minor releases (1.6.1 versus 1.6.0), the C++ ABI stability must be
preserved : no method signature change, no addition of virtual methods, no
new members. Only non-virtual methods can be added.
It may also be helpful to check:
https://abi-laboratory.pro/tracker/timeline/gdal/
2) Delete existing fix_typos directory and run scripts/fix_typos.sh
Process :
1) "make completion" to regenerate scripts/gdal-bash-completion.sh
if new command line switches have been added. scripts/completionFinder.py
must also be edited before if new utilities/scripts are added/removed.
