# Reference point for ABI compliance checks
|
|
#
|
|
# This file lists commits on the current branch that break ABI compatibility in
|
|
# ways that have been deemed acceptable (e.g., removing an extern function with
|
|
# no third-party uses). The primary intent of this file is to control the ABI
|
|
# compliance checks on the buildfarm, but it also serves as a central location
|
|
# to document the justification for each.
|
|
#
|
|
# In general, entries should be added reactively after an abi-compliance-check
|
|
# buildfarm failure. It is important to verify the details of the breakage
|
|
# match expectations, as the first entry listed will become the updated ABI
|
|
# baseline point.
|
|
#
|
|
# Add new entries by adding the output of the following to the top of the file:
|
|
#
|
|
# $ git log --pretty=format:"%H%n#%n# %s%n# %cd%n#%n# <ADD JUSTIFICATION HERE>" $ABIBREAKGITHASH -1 --date=iso
|
|
#
|
|
# Be sure to replace "<ADD JUSTIFICATION HERE>" with details of your change and
|
|
# why it is deemed acceptable.

# AddRelationNotNullConstraints() needs to receive the names of constraints
|
|
# already created, so that it can avoid those names when assigning names to
|
|
# not-null constraints. The purpose of this function is rather obscure, and
|
|
# furthermore it's new in 18, so I don't expect any third-party code to break.

# Modifying GUC tables isn't really an ABI break: the relevant object has

# no calls to MakeTransitionCaptureState() or uses of the
