From 46557d4727de604839d7b7d2de308e734c4c11ee Mon Sep 17 00:00:00 2001 From: Jarek Potiuk Date: Sun, 18 Oct 2026 12:41:34 +0200 Subject: [PATCH 1/9] fix(jira): keep the JVM on IPv4 loopback in the bridge tests The bridge-write tests run bridge.groovy against a mock JIRA server on 127.0.0.1 with a clean environment: PATH, HOME, the tracker variables and the token. That environment drops JAVA_TOOL_OPTIONS, so a shell that sets -Djava.net.preferIPv4Stack=true loses it and the JVM opens an IPv6 socket to the loopback address. Under the agent sandbox on macOS that connect is refused (`SocketException: Operation not permitted`), and every test that reaches the server fails, so the workspace pytest hook failed on every commit that touched a Python tool. The test environment now passes JAVA_TOOL_OPTIONS through with -Djava.net.preferIPv4Stack=true added when it is not there already. IPv4 loopback is harmless everywhere else. All 28 bridge-write tests pass inside the sandbox. No other test starts a JVM with a clean environment.

The byte-identical copy pins stay; the copies are re-synced for the parser docstring's new pointer. The taxonomy gains `contract:body-field` (validator capability set, labels doc, generated labeler config and vendor-neutrality score), the implementing tools declare it, and the issue-template doc, READMEs and specs point at the contract.

[Conformance suite](#conformance-suite) + + + + + +# Body-field contract + +A tracker issue body is a sequence of named fields, each a `### ` heading followed by its value. +Every reader and writer of those fields (the GitHub tool, vetted-ops, the local-files tracker, the Jira bridge, the CVE JSON generator, and any implementation in another language) MUST read and write them by the rules below, so that one body gives one set of fields to all of them. +The rules are written so a reporter's text, however it is formatted, can never become a field or make one field absorb another: in particular, the private mailing-list thread can never be read into the public summary. + +The key words MUST, MUST NOT, SHOULD and MAY are to be read as described in [RFC 2119](https://www.rfc-editor.org/rfc/rfc2119). +Each rule has an identifier (`BF-…`); every case of the [conformance suite](#conformance-suite) names the rule it tests. +The field roles and names a project uses are described in [`tools/github/issue-template.md`](../github/issue-template.md); this document is the authoritative statement of how fields are found. + +## Lines + +- **BF-LINE-1.** A line ends at `\n`, `\r\n` or `\r`, or at the end of the body. An implementation MUST keep each line's ending when it splits, so that joining the lines gives the body back byte for byte. +- **BF-LINE-2.** No other character ends a line: form feed, vertical tab, `U+0085`, `U+2028`, `U+2029` and the like are line content. (Python's `str.splitlines` breaks on them; an implementation MUST NOT use such a splitter.) + +## Field boundaries + +- **BF-BOUND-1.** A line is a *field boundary* if and only if it starts, at column 0, with `###` followed by a space, a tab or the end of the line. A bare `###` is a boundary with an empty name. +- **BF-BOUND-2.** Every field boundary ends the field before it and starts a new section, **whether or not it sits inside a code block**. A field's value is always exactly one section of that split; no fence, Jira macro or duplicate heading can extend it past the next boundary. +- **BF-BOUND-3.** `####`, `###x`, and a `###` line behind indentation, `>` or a list marker are not boundaries. Text before the first boundary is a preamble and belongs to no field. + +## Names + +- **BF-NAME-1.** A boundary's name is the rest of the line with leading and trailing spaces and tabs removed and then a closing run of `#` removed, when that run stands alone or follows a space or tab (`### Severity ##` names `Severity`; `### C#` names `C#`). +- **BF-NAME-2.** Names compare exactly: case-sensitive, inner whitespace significant. Only [normalise](#normalise) with known field names collapses inner whitespace (BF-NORM-3). An implementation MAY offer a lenient lookup (case-folded, whitespace-collapsed) as a documented extension, provided two lenient matches outside closed blocks are a duplicate (BF-SEL-2). + +## Closed code blocks + +A *closed block* is a code block whose opener and closer are both present. Blocks are found by one scan over the whole body, independent of field boundaries. + +- **BF-BLOCK-1.** A CommonMark fence opener is a line of up to three spaces, then a run of three or more backticks or three or more tildes, then an info string. A backtick run whose info string holds a backtick is not an opener. Four or more spaces of indentation is not an opener. +- **BF-BLOCK-2.** A fence is closed by a later line of up to three spaces, then a run of the *same* character at least as long as the opener's, then nothing but spaces or tabs. +- **BF-BLOCK-3.** A Jira block opener is a line that starts, after spaces or tabs, with `{code}`, `{code:}` or `{noformat}`, and does not hold a second occurrence of that macro's name. It is closed by the next line holding the bare macro (`{code}` or `{noformat}`) anywhere. +- **BF-BLOCK-4.** Inside an open block, nothing else opens: a fence inside a `{code}` block, or a `{code}` inside a fence, is content. +- **BF-BLOCK-5.** A block left open at the end of the body is not a closed block: it marks nothing. + +## Which heading is the field + +- **BF-SEL-1.** The field named *N* is the one section named *N* whose boundary lies **outside every closed block**. A boundary inside a closed block never starts a field: a field whose only copies are inside closed blocks is absent (not found), never read from the quoted copy. +- **BF-SEL-2.** Two or more sections named *N* outside closed blocks are a *duplicate*: reading or writing *N* MUST fail, whatever the copies hold. +- **BF-SEL-3.** A field's value is its section's lines after the boundary, with at most one leading blank line and at most one trailing blank line (when the section has more than one line) removed. Other blank lines are kept. +- **BF-SEL-4.** The list of a body's fields is the names of the sections outside closed blocks, in document order, repeats included. + +## Ambiguity: decisions, never guesses + +Some bodies read differently in different renderers. An implementation MUST NOT pick a reading; it reports a *decision* and refuses the field. + +- **BF-CONT-1. Container headings.** A heading-shaped line that is not a boundary (`###` behind indentation, `>` or list markers, any number of them) is content. When it names the requested field and sits outside a fence, as a CommonMark reader pairs fences or as a reader that only accepts fences at column 0 does, reading or writing that field MUST fail as ambiguous. [Normalise](#normalise) reports it as a `container-heading` decision for known field names. +- **BF-MACRO-1. Jira macros opened mid-line.** Jira's renderer opens `{code}` and `{noformat}` anywhere in a line. A line outside closed blocks that, pairing its macros left to right, leaves one open, followed by a later line closing it, with one or more field boundaries between, is a `macro-ambiguous` decision. Reading or writing the field the macro opens in, or any field whose boundary it would hide, MUST fail as ambiguous. A macro opened and closed on the same line is text; one never closed hides nothing. + +## Operations + +Every implementation provides these four operations; a writer of untrusted text also provides the [writer operations](#what-a-writer-must-escape). Errors are one of three kinds: `not_found`, `duplicate` (a not-found kind for callers that only distinguish found from not found) and `ambiguous`. + +### list fields + +- Input: a body. Output: the field names (BF-SEL-4). Never fails. + +### extract + +- Input: a body and a field name. Output: the field's value (BF-SEL-3), with its own line endings. +- **BF-EXT-1.** Fails `ambiguous` under BF-CONT-1 or BF-MACRO-1, checked before anything else; `not_found` when the field is absent (BF-SEL-1); `duplicate` under BF-SEL-2. + +### replace + +- Input: a body, a field name and a new value. Output: the new body. +- **BF-REP-1.** Everything outside the field's value is preserved byte for byte, the heading line included. The value is written in the line-ending convention of the field's heading line; a run of trailing line endings is reduced to one, and a value with content always ends in one. The blank-line spacer after the heading and before the next field is kept when the old value had it. An empty value leaves one spacer line, or none for the last field. Replacing a value with itself returns the body unchanged. +- **BF-REP-2.** Fails as [extract](#extract) does for the field. +- **BF-REP-3.** Fails `ambiguous` when the new value holds a field boundary (BF-BOUND-1) on any line, split by BF-LINE-1 — inside a fence or not. +- **BF-REP-4.** Fails `ambiguous` when the old or the new value holds a heading-shaped line outside fences (behind any indentation, `>` or list marker). +- **BF-REP-5. Whole-body preservation.** Fails `ambiguous` unless the rewritten body has the same sections, each boundary inside or outside closed blocks as before, every other section byte-identical, and no `container-heading` or `macro-ambiguous` decision. A value that opens a fence or a macro reaching past its field is refused this way. + +### normalise + +- Input: a body, optionally known field names and a *keep* map (field name → the input line number of the copy to keep). Output: the canonical text, a list of *changes* `{line, kind}` and a list of *decisions* `{field, kind, lines}`. Line numbers are 1-based lines of the input; changes are ordered by line, then kind. Never fails. +- **BF-NORM-1.** `\r\n` and lone `\r` become `\n`; one `line_endings` change at the first such line. +- **BF-NORM-2.** A fence left open is closed in the field it opens in, after the last non-blank line before the next boundary (`unclosed_fence`, at the opener), unless the closer would move a boundary into or out of a closed block; then it stays open. +- **BF-NORM-3.** A boundary outside closed blocks is rewritten `### ` (`heading`); with known field names, a name equal to one once inner whitespace is collapsed (case kept) takes the known spelling (`heading_name`). Lines inside closed blocks are never rewritten. +- **BF-NORM-4.** Copies of a field outside closed blocks that hold the same value (after stripping) collapse to the first (`duplicate_dropped`, at each dropped heading). Differing copies stay and give a `duplicate` decision listing their heading lines, unless *keep* names one of them, which is kept (`duplicate_resolved`). Copies inside closed blocks are never counted, dropped or reported. +- **BF-NORM-5.** `container-heading` decisions (BF-CONT-1, for known names) and `macro-ambiguous` decisions (BF-MACRO-1: the first hidden field; the opener's line, then each hidden boundary's) are reported, never resolved. +- **BF-NORM-6.** Normalising a normalised body changes nothing. + +## What a writer must escape + +A writer that puts untrusted text (a report, a comment, a scanner finding) into a body provides one or both of two writer operations, and MUST follow the rules below. +Escaping is a leading `\` on the line, which renders as the same visible text and is never parsed as structure; nothing else on the line changes. + +### escape text + +- Input: untrusted text that will become (part of) one field's value. Output: the escaped text. Never fails (a writer MAY refuse text instead of escaping it). +- **BF-WRITE-1.** Every line of the text that is a field boundary (BF-BOUND-1), split by BF-LINE-1, MUST be escaped. Heading-shaped lines behind indentation, `>` or list markers SHOULD be escaped too, for readers that ignore fences (cases tagged `escape-loose`). +- **BF-WRITE-3.** The rule holds inside fences and Jira macros: a writer MUST NOT rely on a block to protect text, since blocks only decide which heading is the field (BF-SEL-1), never where a field ends. + +### escape body + +- Input: a whole body whose own boundaries are its fields (a report a writer stores as is). Output: the escaped body. Never fails. +- **BF-WRITE-2.** Every field boundary inside a closed block (BF-BLOCK-1 to BF-BLOCK-5) MUST be escaped, so quoted text never becomes a copy of a field; boundaries outside closed blocks, and every other line, MUST be left as they are. + A writer SHOULD also close a fence the body leaves open in the field it opens in (as BF-NORM-2 does), never past another field's boundary. + +## Implementations + +| Implementation | Language | Status | Notes | +|---|---|---|---| +| [`tools/github-body-field`](../github-body-field/README.md) (`github_body_field.parser`) | Python | reference | The source every Python copy is pinned to. | +| [`tools/vetted-ops`](../vetted-ops/README.md) (`vetted_ops.body_field_format`) | Python | byte-identical copy | Pinned by `tests/test_body_field_parity.py`. | +| [`tools/local-tracker`](../local-tracker/README.md) (`magpie_local_tracker.body_field_format`, used by `sections`) | Python | byte-identical copy | Pinned by `tests/test_vendored_parser.py`; lenient name lookup (BF-NAME-2).

A second implementation, in the language the Jira bridge is written in, shows that it is and gives Groovy scripts a parser of their own. tools/body-field-contract/groovy/BodyFieldParser.groovy implements every operation of the contract: list fields, extract, replace and normalise, with the not-found, duplicate and ambiguous refusals, the container-heading and macro-ambiguous decisions, whole-body preservation on replace, and the two writer operations (escape text, escape body). It follows the conventions of tools/jira/bridge.groovy and needs nothing beyond the Groovy runtime; it pulls no dependency with @Grab. conformance.groovy beside it reads cases.jsonl and prints one {"id", "result"} line per case. tools/github-body-field/tests/test_conformance.py runs it once per session when `groovy` is on PATH and compares every case with its expected result. Without groovy, the check is skipped and says why. It was executed here with Groovy 6.0.0 on JVM 27: all 98 cases pass. No CI workflow installs Groovy, so in CI this check is skipped; this commit adds no workflow for it. The contract's implementations table, its README and the spec list the Groovy implementation.

On a Git checkout with core.autocrlf, or an SVN one with svn:eol-style=native, a report that reached the working copy with CRLF line endings was rewritten in full by any field-set: every line of it changed, not just the field. A lone CR was turned into a line break as well. Reads now take the file as stored, remember its convention (LF, CRLF or CR, and whether it ends with one) and hand the parser LF lines; writes put that convention back. A field write therefore changes no byte outside the field, whatever the storage did to the file. A file that mixes line endings is refused (exit 4) until it is normalised to one. Expanded svn:keywords ($Id: ... $) are ordinary text to the parser. The store keeps the parser's duplicate or ambiguous error as the cause of its refusal, so callers can tell the two apart. tests/test_storage_conformance.py runs the body-field conformance cases (extract and replace) through the store. Each case body becomes a report in a temporary Git repository with core.autocrlf=true and in a temporary SVN working copy with svn:eol-style=native and svn:keywords. The cases are committed, the field reads and writes run, and the result is committed and read back from a fresh checkout. The field values must match the contract's and the untouched content must be byte-identical. The SVN half skips with a reason when svn or svnadmin is missing; both ran here. Unit tests cover CRLF, CR and LF files, a missing final newline and a file with mixed endings.

It never reports report text. A custom layout is noted, and the descriptor records it. The contract gains a format adapter interface (BF-FMT-1 to BF-FMT-3): the contract's operations, refusals and decisions for one layout's own boundary rule, standard library only, with synthetic-value fixtures beside the adapter. tools/body-field-contract/formats/ is the upstream home for adapters; its _template.py is a working `Name: value` adapter and the skeleton to copy. The conformance runner runs every adapter there, and any named by BODY_FIELD_FORMAT_ADAPTERS: the generic properties every layout shares, and the adapter's own fixtures. `setup config` gains a local-files sub-step, kept in local-files/custom-parser.md so the skill's headings and surface hash stay as they are. When detect says custom, the sub-step: - writes a parser from the template to .apache-magpie-overrides/tools/local-tracker/parsers/.py, with synthetic fixtures and never report text; - runs the conformance suite on it; - enables it only on the user's explicit confirmation of its SHA-256. The new `trust-parser` records `body_parser: {path, sha256}` in the descriptor, and the same hash in the working copy's personal layer, which is never committed. The parser is code that vetted operations run outside the sandbox, so every command loads it only when all of these hold: - the descriptor names it; - its path is a .py file directly in the parser directory, with no `..` and no symlink on the way; - its hash matches both the descriptor and the personal layer. Otherwise the command stops with exit 2, saying to review the change and re-confirm it. A custom layout is never read with the default parser. field-get, field-set and body go through the parser; create and edit with a whole `###` body are refused on a custom layout. A test covers every refusal. setup-override-upstream lists generated parsers and upstreams them as format adapters (cases/parser-adapters.md). A new setup eval suite, config-local-custom-parser, covers four cases: a custom layout, the default layout, a declined parser, and a confirmed one. Self-eval passed 4/4.

Report text comes from outside the team, though, and a report or field value carrying its own \r\n or lone \r was written as it came: the file then mixed conventions, and every later write to that tracker was refused until someone fixed the file by hand. Untrusted text now has its line endings turned into \n before it is escaped, and every write normalises its text before putting the file's convention back, so no write can leave a file mixing them. A file that already mixed them before the tracker touched it is still refused.

That confirmation was not the user's: - On Subversion it lived in /.svn/apache-magpie/. In a repository hosted on Git a .svn/ directory is ordinary committed content, and the working-copy probe takes the nearest .svn/, so one commit carrying a parser, its descriptor entry and a .svn/ trust record got the parser run. - trust-parser only compared the hash it was handed. The confirmation lived in the skill's prose, and the agent ran the command itself, writing the record into the git directory, which a sandboxed command may write. The record now lives in ~/.config/apache-magpie/local-tracker-parsers.json, under the working copy's real path: outside every working copy, so nothing a commit carries can stand in for it, and a path the secure setup never lets a sandboxed command write. trust-parser asks on the controlling terminal and refuses without one, and setup hands the user the command to run in their own terminal instead of running it.

A sandboxed command on a custom-layout tracker therefore could not see the record, and said the parser had to be reviewed and re-confirmed, which cannot help: a new confirmation lands in the same unreadable place. A record the sandbox cannot read now says the parser cannot be verified here and to run the command through vetted operations, which run outside the sandbox; doctor marks that check unverifiable_here. trust-parser, which the user runs in their own terminal, loads the parser after recording it and prints parser_loads, so setup checks that instead of a sandboxed doctor. A default-layout tracker never reads the record. The agent's own file tools are not sandboxed, so the floor now denies Edit(~/.config/apache-magpie/local-tracker-parsers.json), and sandbox-lint requires that deny.
