datavane/tis: technical due diligence, read from its repository
What Borehole read in datavane/tis's code and history at 1e8c188: 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.

What the repository says
LICENSE: Relicensed: AGPL-3.0 → Apache-2.0 (2021-12-07)
Architecture & Codebase — including AI provenance
adequateThe repository begins with most of itself already written
adequateThe first commit carries 457,892 lines — 49% of every line ever added. Whatever happened before that commit happened somewhere this repository cannot show you, so the early history is not available as evidence of how the system was designed.
| 2020-09-26T02:48:49+00:00; +457,892 across 2404 files; subject: 'upgrade to tis-solr2.0' |
Commit messages are templated rather than written
adequate46% of commit subjects are exact repeats of another subject, and subject length varies by only 27.5 characters. A log written by someone explaining their reasoning to a future reader does not look like this. The log is therefore weak evidence of intent, whatever the code is like.

tis-console/src/main/java/com/qlangtech/tis/coredefine/module/action/CoreAction.java is 2,643 lines, 34× this codebase's median file
adequateThe median source file here is 77 lines. 28 files exceed 1,000 lines, the largest being 2,643. 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.

Engineering Process & SDLC Maturity
adequate12% of recent commits change more than 2,000 lines
adequate31 of 269 commits in the last 24 months changed over 2,000 lines of code, not counting reformatting, renames, vendored or generated code. A change that size is rarely reviewed line by line. Ask how they were reviewed, and what made them that large.

Product & Engineering Maturity
strong22 files still carry code deprecated more than two years ago
adequate22 files were marked deprecated over two years ago and still are, the oldest since Sep 2020. A deprecation is a promise to remove. Ask what still depends on these, and whether removing them is scheduled.
tis-hadoop-rpc/src/main/java/com/qlangtech/tis/grpc/MasterJob.java — deprecated since Sep 2020 |
tis-hadoop-rpc/src/main/java/com/qlangtech/tis/rpc/grpc/log/stream/PExecuteState.java — deprecated since Sep 2020 |

Security & Reliability Posture
adequateNone of the standard security guard rails are configured
adequateThere is no disclosure policy, no automated dependency updates, no named code owners and no pre-commit configuration. None of these is load-bearing on its own. Their collective absence says that security posture here is whatever the current team happens to remember to do, which is not a posture that survives the team changing.
| checked 5 kinds of guard rail across 2,779 tracked files; 0 present |
19 dependencies float, and no lockfile is committed
adequateDependency versions are declared as ranges and no lockfile is committed, so a build today does not necessarily produce what a build last month produced. That matters twice over in a transaction: the thing being bought cannot be reproduced exactly, and a compromised upstream release arrives without anyone choosing to take it.
1 Dockerfile runs the application as root
adequateNo USER instruction switches away from root, so the process runs with full privileges inside the container. It is a one-line fix and an ordinary expectation, which is why its absence is worth asking about: it usually says more about whether anyone has reviewed the deployment than about this container specifically.
docker-compose/powerjob/Dockerfile — runs as root |
2 SQL statements built from strings
adequate2 places in product code build SQL by formatting or joining strings rather than passing parameters. 2 of them put a value into the string; in the rest, what the code shows going in is a table or column name, a constant, or something the line does not show. Ask whether any value reaches these strings, rather than a parameter.
tis-collection-info-collect/src/main/java/CreateInsertSql.java:95 — SQL built from a string |
tis-console/src/main/java/com/qlangtech/tis/manage/biz/dal/dao/impl/ApplicationDAOImpl.java:67 — SQL built from a string |
2 of 4 Kubernetes workloads declare no resource limits
adequate2 workload manifests set no CPU or memory limits. One pod that leaks memory or spins can starve everything else on its node, and the scheduler cannot plan capacity for what it cannot see.

tis-k8s/tis-test-mysql.yaml — workload with no limits |
The production build publishes source maps
adequateThe build configuration emits source maps for production, so the original source, with its comments and structure, is downloadable by every visitor. Upload them to an error tracker and keep them off the public server instead.

Relicensed: AGPL-3.0 → Apache-2.0 (2021-12-07)
adequateThe root licence changed 1 time(s). Code taken under earlier terms stays under them; check which terms any fork or customer relied on.
3 advisories against this project in the last 24 months, 3 high or critical
adequateThe newest was published on 2026-08-14. 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 2 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 5.1.0. Answer lives in: the release you run, set against each fixed version. The record is incomplete: NVD: 1 record names tis with nothing tying it to this repository (CVE-2025-40181).

Observability & Operations
adequateNo telemetry or error reporting is wired in anywhere
adequateNone of 2,292 readable files references an instrumentation, metrics or error-reporting library. If this system is in production, nobody learns that it broke from the system itself — they learn it from a customer. That is a reliability finding before it is an observability one.
| searched 2,292 tracked text files for 16 known instrumentation libraries; manifests for metrics, tracing and error-reporting families; locked dependencies for the packages that emit; 0 matched |
No structured logging library is in use
adequateNothing references a structured logging library. Logs that are written to be read by a person are not searchable by a machine, which means incident response here is proportional to how well someone remembers the codebase rather than to what the tooling can find.
| searched 2,292 files for 10 structured logging libraries; 0 matched |
No error reporter is wired in
adequateNothing in the service initialises an error reporter (Sentry, Rollbar, Bugsnag, Honeybadger or an APM agent). An exception in production reaches a person only if someone is reading the logs, which usually means a customer reports it first.
| no error reporter initialised |
4 of 4 deployments run a single replica
adequate4 deployments set `replicas: 1`, and nothing (an autoscaler, a disruption budget) adds more. Every deploy and every node drain is downtime, and the availability the buyer inherits has a ceiling.
