- Two fields of the API's searches other than `q`, for the same four rules:
|
||||||
|
- `query` of the search of unadopted repositories, which holds an owner
|
||||||
|
and a name, such as `alice/python3-app`;
|
||||||
|
- `name` of the search of a repository's milestones.
|
||||||
|
|
||||||
|
- Fields of the package registries' searches:
|
||||||
|
- `text` of the npm registry's search, for the same four rules and the
|
||||||
|
rule for shell paths (932160). An npm name can hold a slash, as
|
||||||
|
`@alice/tools-cli` does.
|
||||||
|
- `searchTerm` of the NuGet v2 API's searches, for the same four rules.
|
||||||
|
These are the searches:
|
||||||
|
- `Search()` and `Packages()`;
|
||||||
|
- `Search()/$count` and `Packages()/$count`, which count their
|
||||||
|
results.
|
||||||
|
- `$filter` of those searches, for the lists of system files and Windows
|
||||||
|
commands (930120, 932120). It holds an expression such as
|
||||||
|
`tolower(Id) eq 'python3'`.
|
||||||
|
- The names `$filter`, `$orderby` and `$top` on those searches, for the
|
||||||
|
rule for MongoDB operators (942290). It refused every such search.
|
||||||
|
- `q` of a Conan search, for the rule for SQL injection (942100), which
|
||||||
|
refused the pattern `zlib/*`. `q` skips it only when the request has
|
||||||
|
one `q`, in the query string or the body. That `q` has the shape of a
|
||||||
|
Conan reference. A reference is a name, then optionally `/` and a
|
||||||
|
version, then optionally `@` and a user, then optionally `/` and a
|
||||||
|
channel. Each part is made of letters, digits, `_`, `.`, `-` and `*`.
|
||||||
|
A part holds no `+`, since 942100 reads `+` as a space. `q` also holds
|
||||||
|
no `*/`, which ends an SQL comment, and no `--`, which starts one.
