Log graph comparision logic is duplicated many times in:
- t3430-rebase-merges.sh
- t4202-log.sh
- t4214-log-graph-octopus.sh
- t4215-log-skewed-merges.sh
This patch consolidates comparision and sanitization logic in
lib-log-graph.
Replaces duplicated code with local and lib helpers - making test
scripts cleaner and more readable.
Closes gitgitgadget issue #471
Signed-off-by: Abhishek Kumar <abhishekkumar8222@xxxxxxxxx>
---
Changes in v3:
- Elaborate on first commit message.
- Fix SP violations in lib-log-graph.
Changes in v2:
- Arrange patches by functions changed instead of files changed.
- Rename library functions by prepending 'lib_'.
- Drop outdated sanitization calls to sed.
- Create specialized helpers to reduce code noise.
- Fix style violations.
