processone/ejabberd: technical due diligence, read from its repository
What Borehole read in processone/ejabberd's code and history at 5ef8f25: its licence, security advisories, releases, review practice, tests, dependencies and operations. Every finding cites the file and line it rests on. The full report also covers the team and asks the questions the code cannot answer.

Architecture & Codebase — including AI provenance
strongsrc/mod_muc_room.erl is 6,026 lines, 34× this codebase's median file
adequateThe median source file here is 176 lines. 10 files exceed 1,760 lines, the largest being 6,026. Size is not a defect on its own — some problems genuinely live in one place — but these are where merge conflicts, review fatigue and single-owner knowledge concentrate, and they are the first thing that slows an inheriting engineer down.

Product & Engineering Maturity
adequateEffort is shifting from building to rewriting
adequateDeleted lines per line added rose from 0.51 to 0.87 between the first and second halves of this history. Rework is normal and often healthy, but a rising ratio means an increasing share of the team's time is spent replacing code that already exists rather than building what does not. Whether that is deliberate repayment or churn is a question for the team.
| first half 0.51, second half 0.87 (split 2014-10-24) |
13% of bug fixes add or change a test
adequateOf 188 fixes in the last 24 months, 25 touched a test. A fix without the test that would have caught the bug can quietly come back, and the suite never learns from what went wrong.

Security & Reliability Posture
strongThe build runs third-party code it does not pin
adequate10 third-party CI actions are referenced by a tag or branch rather than a commit, so they run whatever that tag points to on the day. Tags have been moved to malicious commits in real supply-chain attacks, and a piped script is whatever the server returns that minute. Pinning to a commit is the fix, and it is small.

Relicensed: GPL-2.0 → GPL-with-exception (2004-10-09)
adequateThe root licence changed 1 time(s). Code taken under earlier terms stays under them; check which terms any fork or customer relied on.
1 advisory against this project in the last 24 months, 1 high or critical
adequateThe newest was published on 2026-10-02. A project that publishes advisories is telling its users about its fixes, and the count and pace say how much security work it carries. Whether 1 of them are fixed in the code you ship could not be told from this history: its version is only known to be at least 26.9.0. Answer lives in: the release you run, set against each fixed version. The record is incomplete: NVD: 7 records name ejabberd with nothing tying them to this repository (CVE-2006-2221, CVE-2007-0903, CVE-2009-0934, …).
