Hi all,

Below is *a summary of the divergence* between "*main" (4.3.30) *and "*4.x-master"(4.4 dev). *Repo: github.com/xymon-monitoring/*xymon*

*INTRODUCTION*

*Goal: identify what exists in "main" and is missing in "4.x-master".* Focus on bug fixes and security.

*MISSING COMMITS (GIT commands)* Functional commits present only in main (excluding releases): 28

Scope of unmatched commits:

• 6,489 insertions
• 4,333 deletions
• Net +2,156 LOC (Line of Code) (See Git commands below.)

*MISSING COMMITS without semantic equivalent  (AI powered analysis)* Security / CVE

• 484edeb2 – CVE-2019-* buffer overflow / XSS
• 6dbcd04e – CVE-2016-2056 / 2058 command + JS injection
• 1a4511a7 – CVE-2016-2057 IPC permissions
• df404398 – CVE-2016-2055 config file exposure

Crash / memory safety

• ba47d2f9 – xymongen availability segfault
• 81656c6a – crash on missing allevents
• c3a8a2c9 – RPC buffer size miscalculation
• 4f444be0 – netapp RRD memory leak
• bee6eee8 – double-free in xymond
• 1ab01960 – NULL checks to prevent segfault

Correctness / parsing

• 8ab6c328 – RRD DS comma parsing
• eda84777 – SNMPv3 config parsing
• a123a029 – do_temperature parentheses parsing
• 3f266c08 – do_temperature parsing fixes
• 3227f657 – logfetch off-by-one with triggers
• 95092119 – history logs with dash/underscore names
• 9f62e942 – NONETPAGE parsing tightening

Build / portability

• 4e846f16 – GCC diagnostics guards
• b1414cd8 – stdint.h include tightening
• 3eed090e – Fedora/GCC compile fixes
• 0a546cc1 – avoid unnecessary mod_authz_groupfile loading

Total: 21 commits

*GIT COMMANDS USED *

• Identify unmatched commits: git log --oneline --cherry-pick --left-right main...4.x-master | grep '^<'
• Per-commit size: git show --shortstat
• LOC aggregation: git log --cherry-pick --left-right --numstat main...4.x-master
• Rewrite-aware comparison: git range-diff --stat 4.3.22-root..main 4.3.22-root..4.x-master
• Security commit isolation: git log 4.3.22-root..main --oneline | grep -Ei 'CVE|security|XSS|overflow'

I can make mistakes.
