From b0d5c2c8ae076393e7a3ad59ce875027f4c29304 Mon Sep 17 00:00:00 2001 From: Gilbert Gilb's Date: Fri, 20 Nov 2020 20:38:16 +0100 Subject: headers: Support default header values in Caddyfile with '?' (#3807) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * implement default values for header directive closes #3804 * remove `set_default` header op and rely on "require" handler instead This has the following advantages over the previous attempt: - It does not introduce a new operation for headers, but rather nicely extends over an existing feature in the header handler. - It removes the need to specify the header as "deferred" because it is already implicitely deferred by the use of the require handler. This should be less confusing to the user. * add integration test for header directive in caddyfile * bubble up errors when parsing caddyfile header directive * don't export unnecessarily and don't canonicalize headers unnecessarily * fix response headers not passed in blocks * caddyfile: fix clash when using default header in block Each header is now set in a separate handler so that it doesn't clash with other headers set/added/deleted in the same block. * caddyhttp: New idle_timeout default of 5m * reverseproxy: fix random hangs on http/2 requests with server push (#3875) see https://github.com/golang/go/issues/42534 * Refactor and cleanup with improvements * More specific link Co-authored-by: Matthew Holt Co-authored-by: Денис Телюх --- caddyconfig/httpcaddyfile/directives.go | 18 +++++++----------- 1 file changed, 7 insertions(+), 11 deletions(-) (limited to 'caddyconfig/httpcaddyfile/directives.go') diff --git a/caddyconfig/httpcaddyfile/directives.go b/caddyconfig/httpcaddyfile/directives.go index afa2cd4..4ab8778 100644 --- a/caddyconfig/httpcaddyfile/directives.go +++ b/caddyconfig/httpcaddyfile/directives.go @@ -103,20 +103,11 @@ func RegisterHandlerDirective(dir string, setupFunc UnmarshalHandlerFunc) { return nil, h.ArgErr() } - matcherSet, ok, err := h.MatcherToken() + matcherSet, err := h.ExtractMatcherSet() if err != nil { return nil, err } - if ok { - // strip matcher token; we don't need to - // use the return value here because a - // new dispenser should have been made - // solely for this directive's tokens, - // with no other uses of same slice - h.Dispenser.Delete() - } - h.Dispenser.Reset() // pretend this lookahead never happened val, err := setupFunc(h) if err != nil { return nil, err @@ -201,7 +192,12 @@ func (h Helper) ExtractMatcherSet() (caddy.ModuleMap, error) { return nil, err } if hasMatcher { - h.Dispenser.Delete() // strip matcher token + // strip matcher token; we don't need to + // use the return value here because a + // new dispenser should have been made + // solely for this directive's tokens, + // with no other uses of same slice + h.Dispenser.Delete() } h.Dispenser.Reset() // pretend this lookahead never happened return matcherSet, nil -- cgit v1.2.3
