+     Release/Service Pack anchors for SQL Server 2012-2022.
+     Each release leads with a coarse "major.minor" signature (matches any patch
+     level, so the product year is always resolved) followed by exact RTM/SP base
+     builds (last match wins, so the specific entry overrides the coarse fallback
+     and adds Service Pack identification). 2017+ use the CU servicing model (no SPs).

+# sqlmap architecture
+
+A contributor-oriented map of how sqlmap is put together: the major components,
+how a run flows through them, and where to start looking for a given concern.
+
+> This is a map, not a spec. It describes the durable structure and data flow; for
+> exact signatures, option names, and enumerable lists (tampers, DBMSes, options),
+> the source is authoritative. **When this document disagrees with the code, the code wins.**
+
+sqlmap runs on both Python 2.7 and 3.x; sources are kept pure-ASCII unless a literal
+non-ASCII byte is unavoidable. Compatibility shims live in `lib/core/compat.py` and
+`thirdparty/six`.
+
+---
+
+## 1. Entry points
+
+| Entry | File | Purpose |
+|-------|------|---------|
+| CLI | `sqlmap.py` -> `main()` | the scanner. Applies runtime patches, parses options, runs a scan. |
+| REST API | `sqlmapapi.py` | `-s` server / `-c` client wrappers around `lib/utils/api.py`. |
+
+`main()` (sqlmap.py) does, in order: `dirtyPatches()` (monkey-patches stdlib for
+quirks/security - see below), `setPaths()`, `init()` (option parsing + environment
+setup), then dispatches to `start()` for a normal scan, or to the self-tests
+(`--smoke` / `--vuln-test` / `--api-test`) in `lib/core/testing.py`.
+
+---
+
+## 2. Global state: `conf` and `kb`
+
+Almost everything hangs off two process-global singletons defined in `lib/core/data.py`,
+both `AttribDict` (attribute-accessible dicts; missing keys read back as `None`):
+
+- **`conf`** - the resolved user configuration (options + derived settings). What the
+  user asked for.
+- **`kb`** ("knowledge base") - mutable runtime state discovered during a run
+  (identified DBMS, injection points, page templates, caches, locks, counters).
+
+The configuration pipeline (`lib/core/`):
+
+- `parse/cmdline.py` - argparse definition of every CLI option.
+- `core/optiondict.py` - option name -> type map (used for config-file/API coercion).
+- `core/defaults.py` - default values.
+- `core/option.py` - the heavy lifter: `_setConfAttributes()`, `_setKnowledgeBaseAttributes()`,
+  `_setHTTPHandlers()` (installs the global urllib opener incl. keep-alive), DBMS/encoding
+  setup, etc. Merges CLI + config file + defaults into `conf`/`kb`.
+- `core/settings.py` - constants, version, regexes, thresholds. **New constants go here.**
+
+Identifiers in the codebase are camelCase.
+
+---
+
+## 3. Top-level layout
+
+| Path | Responsibility |
+|------|----------------|
+| `lib/core/` | conf/kb model, common helpers, settings, enums, dump, session, agent, option parsing |
+| `lib/controller/` | the scan orchestrator (`controller.py`), detection checks (`checks.py`), enumeration dispatch (`action.py`), DBMS handler selection (`handler.py`) |
+| `lib/request/` | HTTP layer: `connect.py` (sending), `comparison.py` (the true/false oracle), `inject.py` (value extraction), protocol handlers, response processing |
+| `lib/techniques/` | the exploitation engines: `blind/inference.py`, `error/use.py`, `union/{test,use}.py`, `dns/` |
+| `lib/parse/` | parsing of inputs: CLI, config, HTTP request/log files, HTML, sitemap, and the XML payload/boundary loader (`payloads.py`) |
+| `lib/utils/` | feature modules: `api.py` (REST), `hashdb.py` (session), `crawler.py`, `hash.py` (cracking), `har.py`, `brute.py`, `search.py`, ... |
+| `lib/takeover/` | OS-level takeover: shells, file access, UDF, registry, Metasploit, `xp_cmdshell` |
+| `plugins/generic/` | DBMS-agnostic enumeration/fingerprint/filesystem/takeover base classes |
+| `plugins/dbms/<dbms>/` | per-DBMS subclasses + dialect (one dir per supported DBMS) |
+| `tamper/` | payload-mutation scripts (WAF bypass), one `tamper()` per file |
+| `data/xml/` | the data-driven engine: `boundaries.xml`, `payloads/*.xml`, `queries.xml`, `errors.xml` |
+| `data/` (other) | wordlists/common tables/columns (`txt/`), UDFs (`udf/`), stored procs (`procs/`), shells (`shell/`) |
+| `tests/` | stdlib-unittest suite (offline); see section 11 |
+| `thirdparty/` | vendored dependencies (six, bottle, chardet, ...) - no pip at runtime |
+| `extra/` | auxiliary tools (e.g. `vulnserver` used by `--vuln-test`) |
+
+---
+
+## 4. The scan lifecycle (`lib/controller/controller.py: start()`)
+
+For each target:
+
+1. **Target setup** - `initTargetEnv()` / `setupTargetEnv()` (`lib/core/target.py`):
+   resolve URL/params, open the per-target output dir and session file
+   (`conf.hashDBFile`), and **resume** anything already known (DBMS, injection points,
+   cached values) from the session.
+2. **Connection & profiling** (`lib/controller/checks.py`): `checkConnection()`,
+   `checkWaf()` (fills `kb.identifiedWafs`), `checkStability()` /
+   dynamic-content detection (establishes `kb.pageTemplate`, `kb.matchRatio`).
+3. **Heuristics** - `heuristicCheckSqlInjection()` (cheap error-based hint).
+4. **Detection** - `checkSqlInjection(place, parameter, value)` per parameter, driven by
+   the data engine (section 5). Confirmed points are appended to `kb.injections`.
+5. **Fingerprint & handler** - `lib/controller/handler.py: setHandler()` identifies the
+   back-end DBMS and assigns `conf.dbmsHandler`, the object through which all
+   enumeration is dispatched (section 7).
+6. **Action** - `action()` (`lib/controller/action.py`) routes the requested operation
+   (`--banner`, `--dbs`, `--tables`, `--dump`, `--sql-query`, `--os-shell`, ...) to
+   `conf.dbmsHandler` methods, and feeds results to `conf.dumper`.
+
+If nothing is injectable, the dead-end advisory (level/risk, technique, `--text-only`,
+`--tamper` - definitive when `kb.identifiedWafs` is set) is raised as
+`SqlmapNotVulnerableException`.
+
+---
+
+## 5. The data-driven detection engine
+
+Detection behavior lives in **data, not code** - `data/xml/`, loaded by
+`lib/parse/payloads.py` (`loadBoundaries()`, `loadPayloads()`):
+
+- **`boundaries.xml`** - injection *boundaries*: prefix/suffix pairs and the
+  clause/where/parameter-type context they apply to (e.g. quote vs. numeric contexts).
+- **`payloads/*.xml`** - the *tests*, one file per technique
+  (`boolean_blind`, `error_based`, `inline_query`, `stacked_queries`, `time_blind`,
+  `union_query`), each with the request template and the comparison/grep logic that
+  decides success.
+
+`getSortedInjectionTests()` (`lib/core/common.py`) orders the candidate tests by the
+identified/likely DBMS, `--level`, and `--risk`. The **agent** (`lib/core/agent.py`)
+forges the actual payload string - applying boundary prefix/suffix, the `[RANDNUM]`/
+`[DELIMITER]`-style markers, comments, and tamper scripts. Requests go out via
+`lib/request/connect.py`; the **oracle** `lib/request/comparison.py` decides true/false
+by comparing the response against `kb.pageTemplate` (difflib ratio vs. `kb.matchRatio`,
+plus titles/errors/HTTP-code signals).
+
+---
+
+## 6. Exploitation techniques
+
+Once a parameter is injectable, value extraction is dispatched by
+`lib/request/inject.py: getValue()` to the matching engine in `lib/techniques/`:
+
+| Technique | Engine | Mechanism |
+|-----------|--------|-----------|
+| boolean-based blind | `blind/inference.py: bisection()` | binary-search each character via true/false oracle |
+| time-based blind / stacked | `blind/inference.py` (time compare) | same bisection, oracle is a measured delay |
+| error-based | `error/use.py: errorUse()` | parse the value straight out of a provoked DB error |
+| UNION query | `union/{test,use}.py` | column-count detection then `UNION SELECT` extraction |
+| inline query | (inline, via inject) | value embedded in the original query position |
+| DNS exfiltration | `dns/` | `--dns-domain` out-of-band channel |
+
+`bisection()` is the hot loop; it caches the `--charset` table in
+`kb.cache.charsetAsciiTbl` and respects the `kb.disableShiftTable` runaway-guard latch
+(intentional). Multi-threaded extraction is coordinated via `kb.locks` and
+`getCurrentThreadData()` (`lib/core/threads.py`).
+
+---
+
+## 7. DBMS abstraction
+
+Enumeration is DBMS-agnostic at the top and specialized underneath:
+
+- **`plugins/generic/`** - base classes for each concern: `fingerprint.py`,
+  `enumeration.py`, `databases.py`, `entries.py`, `users.py`, `filesystem.py`,
+  `takeover.py`, `syntax.py`, `misc.py`, `search.py`, `custom.py`, `connector.py`
+  (direct DB connection for `-d`).
+- **`plugins/dbms/<dbms>/`** - one directory per supported DBMS, subclassing the generic
+  pieces and supplying dialect specifics.
+- **`data/xml/queries.xml`** - per-DBMS SQL query templates (banner, current user, table
+  enumeration, casting, etc.) keyed by DBMS. The generic code asks for a query by name;
+  the dialect comes from XML.
+
+`conf.dbmsHandler` (set in `handler.py`) is the live object that `action()` calls into.
+
+---
+
+## 8. Output and session
+
+- **Output** - `conf.dumper` is a `Dump` instance (`lib/core/dump.py`): console tables
+  plus per-table file export in CSV / HTML / SQLITE / JSONL (`--dump-format`). Logging
+  is via `logger` (`lib/core/log.py`).
+- **Session / resume** - each target gets a SQLite session file
+  (`<output>/<host>/session.sqlite`). `hashDBWrite()` / `hashDBRetrieve()`
+  (`lib/core/common.py`, backed by `lib/utils/hashdb.py`) cache injection points,
+  fingerprint, and extracted values so a re-run *resumes* instead of re-testing
+  (`--flush-session` discards it; `--fresh-queries` ignores cached query results). A
+  stale-session nudge fires on resume when the file is older than `HASHDB_STALE_DAYS`.
+
+---
+
+## 9. Request layer and tampering
+
+`lib/request/connect.py` (`Connect.getPage`) is the single HTTP chokepoint. Around it:
+protocol handlers (`httpshandler`, `redirecthandler`, `chunkedhandler`, `rangehandler`,
+persistent connections via `lib/request/keepalive.py`), response processing (`basic.py`), and the
+comparison oracle (`comparison.py`).
+
+**Tamper scripts** (`tamper/`) mutate the payload just before sending to evade WAF/IPS.
+Each file exposes a `tamper(payload, **kwargs)` and a `__priority__`; `--tamper=a,b,c`
+chains them in priority order. They are payload-string transforms only (no engine
+coupling), which is why they compose freely.
+
+---
+
+## 10. REST API and JSON report
+
+`lib/utils/api.py` runs a Bottle server (`sqlmapapi.py -s`) that drives sqlmap scans as
+subprocesses and exposes them over HTTP. Key pieces: `DataStore`/`Task` (task registry),
+an IPC SQLite `Database` (the subprocess writes results/logs/errors back through
+`StdDbOut`), and the route handlers (`/task/*`, `/option/*`, `/scan/*`, `/version`, ...).
+The contract is documented in `sqlmapapi.yaml` (OpenAPI) and `REST-API.md`.
+
+`--report-json` reuses the *same* assembly code (`_assembleData` / `_sanitizeScanData`)
+that the `/scan/<id>/data` endpoint uses, so the CLI report and the API result can't
+drift; `RESTAPI_VERSION` is the API contract version (major exposed as integer).
+
+---
+
+## 11. Tests and self-tests
+
+Two complementary layers:
+
+- **Offline unit/regression suite** (`tests/`) - stdlib `unittest` only (no pytest/pip),
+  green on py2 + py3. `_testutils.py` bootstraps global state and provides the
+  property/fuzz harness (`Rng` - a cross-version-identical PRNG - and `for_all`). Run:
+  `python -B -m unittest discover -s tests -p "test_*.py"` (`-B` matters: a cached `.pyc`
+  makes a `getFileType(__file__)` doctest see `binary`).
+- **In-tree self-tests** (`lib/core/testing.py`, hidden switches): `--smoke-test`
+  (doctests + regex sanity over the whole tree), `--vuln-test` (end-to-end scans against
+  the bundled `extra/vulnserver`), `--api-test` (live REST round-trip). The CI workflow
+  (`.github/workflows/tests.yml`) runs all of these.
+
+---
+
+## 12. "Where do I start for ...?"
+
+| I want to change... | Start in |
+|---------------------|----------|
+| a CLI option | `lib/parse/cmdline.py` (+ `optiondict.py`, `defaults.py`) |
+| a constant/threshold | `lib/core/settings.py` |
+| how injection is *detected* | `data/xml/boundaries.xml` + `data/xml/payloads/*.xml`, then `lib/controller/checks.py` |
+| how a value is *extracted* | `lib/request/inject.py` + the relevant `lib/techniques/` engine |
+| the true/false decision | `lib/request/comparison.py` |
+| a per-DBMS query/dialect | `data/xml/queries.xml` + `plugins/dbms/<dbms>/` |
+| enumeration behavior | `plugins/generic/*.py` |
+| dump/output format | `lib/core/dump.py` |
+| a WAF-bypass transform | add a file under `tamper/` |
+| the REST API surface | `lib/utils/api.py` (+ keep `sqlmapapi.yaml` in sync) |
+| session/resume behavior | `lib/utils/hashdb.py` + `hashDB*` in `lib/core/common.py` |
+| a stdlib monkey-patch / security shim | `lib/core/patch.py` |

+# HTTP/2 "timeless timing" oracle (Van Goethem et al., USENIX Security 2020) built on the native
+# client's exchange_pair() primitive (lib/request/http2.py). Two requests are coalesced into a single
+# TCP write and multiplexed on one connection; because they share the packet and the path, network
+# jitter hits both equally and cancels, so the RELATIVE order in which their responses complete reflects
+# only the server-side processing delta. That lets a millisecond (or sub-ms) difference in query work be
+# read that absolute wall-clock timing, drowned by jitter, cannot resolve - and it needs no SLEEP: the
+# NATURAL execution-time gap between a true and a false boolean branch is signal enough on most engines.
+#
+# The oracle is only valid when the target processes the two streams CONCURRENTLY; a serializing
+# front-proxy makes order track arrival, not work. calibrate() detects that (and estimates the readable
+# delta) so the caller never applies the oracle blind - it falls back to classic time-based instead.

+# [COST] the calibrator dials UP from a small default until the response-order signal is reliable. That
+# self-tunes to the lightest payload that works - fast, and never allocates a huge blob.
+# [COST] is replaced with a row count; each primitive is a scalar sub-select doing ~[COST] units of
+# bounded work. Grouped by dialect and keyed on sqlmap's canonical DBMS names (DBMS.* enum) so a fork
+# (MariaDB->MySQL, CockroachDB->PostgreSQL, ...) resolves via its base DBMS, and there is no string drift.
+# A DBMS absent here (or whose primitive is wrong on a given target) simply fails calibration and the scan
+# falls back to classic time-based - the light-heavy is always safety-gated, never applied blind.
+#
+# SCOPE: timeless layers on top of a DETECTED time-based technique, so it can only ever engage on a DBMS
+# that ships a time-based payload (data/xml/payloads/time_blind.xml): PostgreSQL, MySQL (+MariaDB/TiDB),
+# Oracle, Microsoft SQL Server, Sybase, SQLite, Firebird, ClickHouse, IBM DB2, Informix, HSQLDB, SAP MaxDB.
+# Engines with NO time-based payload (H2, MonetDB, CrateDB, Vertica, Presto/Trino, Snowflake) are never
+# detected as injectable via time, so a light-heavy primitive for them is dead code - they are NOT listed.
+#
+# GATING & SAFETY: the heavy work must run for exactly ONE of a boolean condition and its negation, so
+# response ORDER names the bit. It is gated by the shipped-vector shape `[RANDNUM]=(CASE WHEN (cond) THEN
+# (<heavy>) ELSE [RANDNUM] END)` - the THEN branch does the work iff cond holds, the ELSE is a cheap literal.
+# Some optimisers HOIST an uncorrelated scalar subquery out of the CASE and run it in BOTH branches (seen on
+# TiDB with `(SELECT BENCHMARK(N,MD5(1)))`; MySQL 8.4 does not). That is not a correctness hazard here: when
+# both branches do equal work the measured delta is ~0, so tuneHeavy's MIN_HEAVY_MS gate REJECTS the rung
+# and the scan falls back to classic time-based - correct data, just no timeless speedup. Corruption only
+# ever came from ENGAGING with a tiny-but-nonzero delta that flips under load; requiring MIN_HEAVY_MS of
+# real server-side delay (not just a reliable idle order) is the fix for that, and it is primitive-agnostic.

+# *semantics* alone - no SQL keywords, functions, quotes or schema names. It complements
+# heuristicCheckDbms() (which uses (SELECT 'x')='x' string round-trips): the dialect probes carry
+# no SELECT/quote, so they can narrow the back-end DBMS where those are dropped (e.g. a
+# keyword-matching WAF/IPS, or when kb.droppingRequests has it skipped entirely).
+#
+# Each probe is evaluated through checkBooleanExpression(), i.e. as an appended boolean
+# (... AND (<probe>)), which yields a clean true/false from the comparison oracle. (A value-position
+# variant - replacing the value with id=2^0 etc. - was prototyped and rejected: those probes land on

+    Runs a sqlmap scan in a dedicated subprocess and returns its structured result (library usage).
+
+    Keyword options are plain sqlmap option names - exactly the names used in a sqlmap configuration
+    file (data/sqlmap.conf) and by the REST API, i.e. the 'conf' names, NOT command line switches. So
+    scan(url, technique="BEU", getBanner=True, dumpTable=True, tbl="users", level=3) is equivalent to
+    the config file lines 'technique = BEU', 'getBanner = True', 'dumpTable = True', 'tbl = users',
+    'level = 3'. Unknown names are rejected. The scan is driven through a generated config file passed
+    with '-c' (the same mechanism the REST API uses), so there is a single option namespace and no
+    argument escaping. 'raw' takes a list of extra raw command line switches for the rare thing not
+    expressible as a config option (e.g. raw=["--fresh-queries"]).
+
+    The engine runs fully out-of-process, so a scan can never affect the calling process (no shared
+    global state, no HTTP-stack patching, no risk of the host being exited). The return value is the
+    parsed '--report-json' report - the same structure as the REST API '/scan/<id>/data' response: a
+    dict with keys 'success', 'data' (a list of {'type_name', 'value'} entries: TARGET, TECHNIQUES,
+    BANNER, DUMP_TABLE, ...), 'error' and 'meta'.
+
+    scan() is blocking and thread-safe, so it is both thread- and asyncio-ready: run several at once
+    in threads, or from an event loop with 'await loop.run_in_executor(None, functools.partial(scan,
+    url, dumpTable=True))'. For unattended/concurrent use the run is hardened like the REST API
+    subprocess: batch mode (never prompts) with stdin closed, isolated file descriptors, its own
+    output directory (so parallel scans of the same target can not collide on session/dump files and
+    nothing accumulates on disk), engine output streamed to a temporary file rather than buffered in
+    memory, and - when 'timeout' is set - the whole subprocess group is torn down on expiry. Pass
+    'outputDir' to keep the run's files.

+This file merges the agent.py tests previously spread across
+test_agent.py, test_agent_dialects.py, test_core_more.py and
+test_core_extra.py:
+
+  * Payload assembly helpers (DBMS-independent string transforms that wrap,
+    fold and clean a payload on its way to the wire): prefix/suffix, payload
+    delimiters, field extraction, CONCAT folding, RAND-marker cleanup.
+
+  * Cross-dialect exercise of the payload-assembly helpers. agent.py builds SQL
+    payloads from per-DBMS dialect templates (queries.xml); the helpers are pure
+    given the identified back-end DBMS, so driving each one across EVERY
+    supported dialect walks the dialect-specific branches (CAST forms,
+    concatenation operators, LIMIT/TOP/ROWNUM shapes, ...) without a live target.
+
+  * Argument-combination / shape coverage for forgeUnionQuery, limitQuery,
+    whereQuery, getComment, concatQuery(unpack=False), cleanupPayload markers,
+    adjustLateValues, getFields shapes, prefix/suffix args, nullAndCastField
+    noCast, plus the pure agent helpers (extractPayload/replacePayload, ...).

+Unit tests for the sqlmap REST API (lib/utils/api.py).
+
+Two complementary angles:
+  1. Pure helpers / objects called directly (is_admin, validate_task_options,
+     the Database and Task classes, the StdDbOut/LogRecorder IPC writers).
+  2. The bottle HTTP routes driven through the WSGI app via a minimal in-process
+     test client (no sockets, no network, no scan subprocess) - task lifecycle,
+     option get/set, scan status/data/log, admin list/flush, version, auth.
+
+The scan-data assembler/collector helpers (_storeData / _assembleData /
+_sanitizeScanData / _cleanIdentifier / writeReportJson) are pinned separately in
+test_report.py; here we focus on what that file does not exercise.

+BigArray disk-spill semantics (lib/core/bigarray.py).

+BigArray is the structure that lets sqlmap dump tables far larger than RAM: once
+the in-memory chunk exceeds chunk_size it is pickled to a temp file and a new
+chunk starts. The tricky, easy-to-break part is that indexing / iteration /
+pop / pickling must stay correct ACROSS the in-memory<->on-disk boundary.

+Unit tests for lib/controller/checks.py driven with a MOCKED HTTP layer.
+
+checks.py is the injection-detection controller; almost everything in it goes
+through the network seam (lib.request.connect.Connect, imported into the module
+as `Request`). By monkeypatching `Request.queryPage` / `Request.getPage` to
+return canned (page, headers/ratio, code) tuples - and stubbing `agent.payload`
+where the real payload machinery would require a fully-built target - the
+decision logic of each check (the kb.*/conf.*/return-value verdict) can be
+exercised offline, without a live target, DBMS, or DNS.
+
+Every test snapshots and restores the conf/kb fields it touches AND every
+module attribute it monkeypatches, so ordering between tests (and with the rest
+of the suite) is irrelevant. conf.batch is forced on to avoid interactive
+prompts, and readInput is stubbed per-test where a branch would prompt.

+Consolidated unit coverage for lib/core/common.py.
+
+This module merges the previously separate test_common_utils.py,
+test_common_parsers.py and the common.py-specific classes from
+test_core_more.py, test_core_extra.py and test_core_final.py into a single
+file. Test logic is unchanged from those sources.
+
+Everything runs in isolation (no network, no DBMS, no persistent filesystem
+mutation of the project). Any function that reads/writes global conf/kb/Backend
+state has that state saved and restored around the call so test ordering stays
+irrelevant. Temp files go to the session scratchpad and are removed.
+
+stdlib unittest only (no pytest / no pip); works on Python 2.7 and 3.x.

+  * jsonMinimize() (lib/core/common.py): the order-independent leaf-path projection.
+  * comparison() (lib/request/comparison.py): when the response Content-Type is JSON, the
+    similarity ratio is computed over that projection instead of raw text - so key
+    reordering / whitespace noise no longer perturbs it (false-positive fix) and a small
+    value/structure change is no longer drowned out in a large body (false-negative fix).
+
+The headline tests assert the JSON path is *better* than the text path on the same inputs,
+not merely that it runs; and that any non-JSON / unparseable / explicit-mode case falls
+back to the exact text behavior (so the HTML oracle is untouched).

+
+DBMS-specific enumeration overrides (plugins/dbms/<dbms>/enumeration.py),
+driven through each full DBMS handler with the injection layer mocked, so the
+dialect-specific table/column/user/privilege discovery paths run without a live
+target, network, or DBMS. The in-band (UNION/error/direct) branch is taken via
+conf.direct=True and inject.getValue is stubbed with canned result rows;
+conf.batch=True avoids interactive prompts.
+
+Consolidated from former tests/test_dbms_enum.py (Microsoft SQL Server),
+tests/test_dbms_enum_a.py (Oracle/PostgreSQL/MySQL/SQLite) and
+tests/test_dbms_enum_b.py (Sybase/MaxDB/MSSQL extra/DB2/Informix/Firebird/HSQLDB).
+
+stdlib unittest only (no pytest / no pip); works on Python 2.7 and 3.x.

+
+The DNS-exfiltration extraction engine (lib/techniques/dns/use.py dnsUse) and the
+channel-detection probe (lib/techniques/dns/test.py dnsTest).
+
+DNS exfil is normally driven by a back-end DBMS that performs an actual DNS lookup
+of an attacker-controlled hostname (Oracle UTL_INADDR, MSSQL xp_dirtree, ...),
+encoding the queried data in the subdomain labels which then reach sqlmap's
+in-process DNS server. That DBMS behaviour cannot be reproduced locally without a
+real DNS-emitting engine, so here we drive the REAL dnsUse()/dnsTest() logic + the
+REAL DNSServer (on a high port, no root) and emulate ONLY that one step: a mock
+Request.queryPage plays the DBMS - it takes the per-iteration boundaries dnsUse
+generated and fires a genuine UDP DNS query for
+'prefix.<hex chunk of the secret>.suffix.domain' at the DNS server.
+
+So the chunking/offset/reassembly loop, the dns_request snippet rendering, the
+DNSServer packet parse, pop(prefix,suffix), regex extraction, hex decoding and the
+detection-then-disable logic are all exercised for real; if any of them regress
+these go red - without a live DBMS.
+
+NOTE on fidelity: secrets are kept ASCII so the mock's byte-slice chunking matches a
+DBMS character-substring exactly. Multi-byte (UTF-8) values, where DBMS SUBSTRING is
+character-based and a chunk could split a code point, need the real-DBMS run.

+Output formatting of the result dumper (lib/core/dump.py) and the SQLite
+replication backend (lib/core/replication.py).
+
+dump.Dump turns extracted DB structures (schemas, table/column listings, row
+counts, single facts, user lists) into the human-readable ASCII tables printed
+to the console, and serializes per-table row data to CSV / HTML / SQLite files.
+None of that needs a live target, network or DBMS: the console renderers route
+every line through Dump._write (overridden here to capture instead of print),
+and the file renderers just write to a path we point at a temp dir. These tests
+pin the rendered layout/escaping contracts so a formatting regression is caught
+without an end-to-end scan.

+JSONL output of the per-table dumper (Dump.dbTableValues in lib/core/dump.py).
+
+--dump-format=JSONL writes one self-describing JSON object per row to a
+<host>/dump/<db>/<table>.jsonl file, streaming-safe (one independent line per
+row, no surrounding array/header/footer). These tests pin the contract that an
+automated consumer relies on: column order preserved (so it matches the CSV
+column order and is reproducible on Python 2's unordered dict), the DB-NULL
+marker (" ") mapped to JSON null exactly like --report-json, the empty string
+left intact (NOT collapsed to null), and a strict one-object-per-line layout.

+
+The error-based extraction engine (lib/techniques/error/use.py _oneShotErrorUse).
+
+Error-based SQLi coaxes the DBMS into emitting the target value inside an error
+message, wrapped between two random delimiters (kb.chars.start/stop). The engine
+fires the payload and pulls the value back out with a regex. We drive the REAL
+_oneShotErrorUse against a mock oracle whose "error page" embeds a known secret
+between those delimiters, and assert it recovers the value exactly - no live DBMS.
+
+Requires an error-technique injection context (kb.injection.data[...].vector with
+[QUERY], plus the parameter context agent.payload needs). kb.errorChunkLength is
+pre-set so the MySQL/MSSQL chunk-length probing loop is skipped.

+Exercised against a REAL temporary SQLite file (no network, no DBMS): scalar
+write/retrieve, serialized round-trip for every container type sqlmap stores,
+overwrite semantics, missing-key -> None, and key-hash determinism.
+
+This is also the end-to-end regression for the base64-pickle bytes fix: a

+cycle on both Python 2 and 3 (it silently failed on py3 before the patch.py fix).

+The blind-SQLi extraction engine (lib/techniques/blind/inference.py bisection).

+This is the actual algorithm that pulls data out one character at a time over a

+here we drive the REAL bisection() against a mock oracle: Request.queryPage is
+replaced with a function that decodes the forged payload (we control the payload
+template, so it is trivially parseable) and answers the comparison against a
+known secret. If bisection's binary search, charset narrowing, or value assembly
+regress, these go red - without a live target.
+
+Also asserts the search is logarithmic (binary search), not a linear scan of the

+is the exact thing that silently drifts when an endpoint is added/renamed/retyped.

+in BOTH directions - no undocumented route, no phantom spec entry - plus that the
+spec's advertised version matches the runtime RESTAPI_VERSION.
+
+PyYAML is not bundled (and the suite is stdlib-only / no pip), so the spec is read

+Property/fuzz tests for the pure parsers and transforms. Where the other test
+files pin specific examples, these assert INVARIANTS over hundreds of randomized
+(but deterministic, cross-version-identical - see _testutils.Rng) inputs, which is
+the cheap net for the edge-bug class that example tests miss (commas inside quoted
+literals / nested parens, NUL / 0xff / astral code points in codecs, etc.).
+
+Property families:
+  - codec/serializer pairs round-trip: decode(encode(x)) == x
+  - structure transforms preserve their contract (flat/de-arrayized/permutation)
+  - string transforms hold their stated invariant (ASCII-only, no newlines, ...)
+  - random helpers respect length / alphabet / range bounds
+  - splitFields/zeroDepthSearch partition faithfully and never cut inside a group
+  - a batch of transforms never raise on arbitrary input
+
+On failure _testutils.for_all prints the exact offending input + its case index so
+it reproduces on any interpreter.

+
+Exhaustive lock on the safe (JSON-based, no code execution) serializer that backs the
+session store (HashDB) and BigArray disk chunks - the replacement for the former
+code-executing serializer.
+
+Two properties must hold forever, on BOTH Python 2.7 and 3.x:
+
+  1. CORRECTNESS - every value sqlmap actually persists must round-trip losslessly, with
+     its exact type. The historically fragile cases are covered explicitly: integer/tuple
+     dict keys (naive JSON turns them into strings), tuple-vs-list, set/frozenset, bytes,
+     the AttribDict/InjectionDict/RawPair classes and their internal state, and the native
+     DB-driver scalars (Decimal/datetime/...) that '-d' direct-mode output can contain.
+     A regression here silently corrupts a user's saved session.
+
+  2. SECURITY - deserialization must NEVER execute code and must reconstruct ONLY the small
+     explicit class allowlist. Any other class name (os.system, subprocess.Popen, eval,
+     lib.core.common.shellExec, ...) must be refused with a "forbidden" ValueError, and a
+     crafted legacy payload must fail inertly (no side effects).
+
+Kept deliberately verbose - each case maps to a real session/BigArray value or a real report.

+Unit tests + atom-level SQL coverage for lib/utils/sqllint.py.
+
+Two concerns:
+
+  1. Linter self-test - a curated set of well-formed fragments/statements that
+     must NOT flag, malformed ones that MUST flag, and the cross-dialect edge
+     cases the linter has learned (==, ::, $/backtick identifiers, LIKE() as a
+     function, HSQLDB "LIMIT off lim", ...). Guards the linter from regressions.
+
+  2. Atom-level SQL coverage - every SQL-bearing template in data/xml/queries.xml
+     and data/xml/payloads.xml, across ALL back-end DBMSes, must lint structurally
+     clean. This is a coverage gate over the *building blocks* of every query
+     sqlmap emits. The composed/runtime layer (agent.py wrapping these atoms into
+     wire payloads) is exercised faithfully by the separate payload-lint walk; a
+     0-flag result here means the catalog itself is sound in all 30 dialects.
+
+A regression (a newly malformed catalog entry, OR a genuinely new valid dialect
+construct the linter does not yet understand) makes the relevant test fail with a
+pointer to the offending template.

+stdlib unittest only; Python 2.7 and 3.x; pure-ASCII.

+Tamper scripts (all ~70): contract, robustness on a payload battery, known
+transforms, and documented fragile cases.
+
+NOTE (flagged for author - real minor bugs surfaced by this suite):
+  * tamper/percentage.py raises UnboundLocalError on empty/None payload
+    (retVal is only assigned inside `if payload:`; missing `retVal = payload` init).
+  * tamper/escapequotes.py raises AttributeError on None payload (no guard).
+  68/70 tampers handle ""/None gracefully; these two are inconsistent. Pinned below
+  as KNOWN_FRAGILE so the suite stays green and a fix is a conscious change.

+Target-environment setup in lib/core/target.py.
+
+target.py wires a single scan's per-host state together: it derives the output /
+dump / files directories from the hostname, opens (and optionally flushes) the
+HashDB session file, resumes a previously-fingerprinted DBMS/OS and stored kb
+values out of that session, decides the custom injection marker, normalizes the
+POST body (url-decode / base64), splits GET/POST/Cookie/header strings into the
+testable paramDict, and restores the per-target merged options between targets.
+
+None of that needs a live HTTP target or a real DBMS connection: every function
+reads conf/kb globals (which are set up here per-test and restored in tearDown)
+and at most touches the local filesystem (pointed at a private temp tree) or a
+local SQLite session file. Those side-effecting paths are still pure with
+respect to the network, so they are exercised here against real temp dirs.
+
+All expected values below were probed from actual output, not assumed.

+
+The UNION-based column-count detection engine (lib/techniques/union/test.py).
+
+_findUnionCharCount discovers how many columns a UNION injection needs. Its
+fastest path is the ORDER BY technique: a valid target accepts ORDER BY 1..N and
+errors on ORDER BY N+1, so it binary-searches for N. We drive the REAL function
+against a mock oracle (Request.queryPage replaced) that errors once the requested
+column index exceeds a known true count - exercising the actual detection +
+binary search with no live target.
+
+This requires the full injection context (conf.parameters / conf.paramDict /
+kb.injection) because column detection builds real payloads via agent.payload.

-"""An HTTP handler for urllib2 that supports HTTP 1.1 and keepalive.
-
->>> import urllib2
->>> from keepalive import HTTPHandler
->>> keepalive_handler = HTTPHandler()
->>> opener = _urllib.request.build_opener(keepalive_handler)
->>> _urllib.request.install_opener(opener)
->>>
->>> fo = _urllib.request.urlopen('http://www.python.org')
-
-If a connection to a given host is requested, and all of the existing
-connections are still in use, another connection will be opened.  If
-the handler tries to use an existing connection but it fails in some
-way, it will be closed and removed from the pool.
-
-To remove the handler, simply re-run build_opener with no arguments, and
-install that opener.
-
-You can explicitly close connections by using the close_connection()
-method of the returned file-like object (described below) or you can
-use the handler methods:
-
-  close_connection(host)
-  close_all()
-  open_connections()
-
-NOTE: using the close_connection and close_all methods of the handler
-should be done with care when using multiple threads.
-  * there is nothing that prevents another thread from creating new
-    connections immediately after connections are closed
-  * no checks are done to prevent in-use connections from being closed
-
->>> keepalive_handler.close_all()
-
-EXTRA ATTRIBUTES AND METHODS
-
-  Upon a status of 200, the object returned has a few additional
-  attributes and methods, which should not be used if you want to
-  remain consistent with the normal urllib2-returned objects:
-
-    close_connection()  -  close the connection to the host
-    readlines()         -  you know, readlines()
-    status              -  the return status (ie 404)
-    reason              -  english translation of status (ie 'File not found')
-
-  If you want the best of both worlds, use this inside an
-  AttributeError-catching try:
-
-  >>> try: status = fo.status
-  >>> except AttributeError: status = None
-
-  Unfortunately, these are ONLY there if status == 200, so it's not
-  easy to distinguish between non-200 responses.  The reason is that
-  urllib2 tries to do clever things with error codes 301, 302, 401,
-  and 407, and it wraps the object upon return.
-
-  For python versions earlier than 2.4, you can avoid this fancy error
-  handling by setting the module-level global HANDLE_ERRORS to zero.
-  You see, prior to 2.4, it's the HTTP Handler's job to determine what
-  to handle specially, and what to just pass up.  HANDLE_ERRORS == 0
-  means "pass everything up".  In python 2.4, however, this job no
-  longer belongs to the HTTP Handler and is now done by a NEW handler,
-  HTTPErrorProcessor.  Here's the bottom line:
-
-    python version < 2.4
-        HANDLE_ERRORS == 1  (default) pass up 200, treat the rest as
-                            errors
-        HANDLE_ERRORS == 0  pass everything up, error processing is
-                            left to the calling code
-    python version >= 2.4
-        HANDLE_ERRORS == 1  pass up 200, treat the rest as errors
-        HANDLE_ERRORS == 0  (default) pass everything up, let the
-                            other handlers (specifically,
-                            HTTPErrorProcessor) decide what to do
-
-  In practice, setting the variable either way makes little difference
-  in python 2.4, so for the most consistent behavior across versions,
-  you probably just want to use the defaults, which will give you
-  exceptions on errors.
