bug#10109: [PATCH] (web http): list-style headers do not validate

[Daniel Hartwig]

Package: guile
Version: 2.0.3
Tags: patch

Many of the list-style headers from (web http) do not validate
correctly.  The test suite only checks that the header's parse and
does not test the associated validators.

Attached is a very quick patch (0002) which exposes the failing
validators through the test-suite:

$ ./guile-test tests/web-http.test

Totals for this test run:
passes:                 60
failures:               20

The other patch (0001) corrects `http.scm' for some typos and missing logic,
after which the above failures no longer occur.

0001 (web http): fix validators for various list-style headers

* module/web/http.scm (default-val-validator): Valid with no value.
  (key-value-list?): Keys are always symbols, do not accept strings.
  (validate-param-list): Apply `valid?' to list elements.
  (validate-credentials): Validate param for Basic scheme, which
  is parsed as a string.
  (declare-symbol-list-header!): `list-of?' args were in wrong order.
  ("Cache-Control"): Replace `default-val-validator' with more
  specific procedure.
  ("Accept"): Validate on first param which has no value.
