Do not vendor dependencies. As a security package, were we to vendor dependencies the projects that then vendor bluemonday may not receive the latest security updates to the dependencies. By not vendoring dependencies the project that implements bluemonday will vendor the latest version of any dependent packages. Vendoring is a project problem, not a package problem. bluemonday will be tested against the latest version of dependencies periodically and during any PR/merge. +2. I do not care about spelling mistakes or whitespace and I do not believe that you should either. PRs therefore must be functional in their nature or be substantial and impactful if documentation or examples. ## Submitting an Issue diff --git a/vendor/github.com/microcosm-cc/bluemonday/go.mod b/vendor/github.com/microcosm-cc/bluemonday/go.mod index 02cf2eac3..0e9028a62 100644 --- a/vendor/github.com/microcosm-cc/bluemonday/go.mod +++ b/vendor/github.com/microcosm-cc/bluemonday/go.mod @@ -3,7 +3,8 @@ module github.com/microcosm-cc/bluemonday go 1.16 require ( + github.com/asaskevich/govalidator v0.0.0-20210307081110-f21760c49a8d github.com/aymerick/douceur v0.2.0 github.com/gorilla/css v1.0.0 // indirect - golang.org/x/net v0.0.0-20210610132358-84b48f89b13b + golang.org/x/net v0.0.0-20210614182718-04defd469f4e ) diff --git a/vendor/github.com/microcosm-cc/bluemonday/go.sum b/vendor/github.com/microcosm-cc/bluemonday/go.sum index 930d271e3..049d51658 100644 --- a/vendor/github.com/microcosm-cc/bluemonday/go.sum +++ b/vendor/github.com/microcosm-cc/bluemonday/go.sum @@ -1,3 +1,5 @@ +github.com/asaskevich/govalidator v0.0.0-20210307081110-f21760c49a8d h1:Byv0BzEl3/e6D5CLfI0j/7hiIEtvGVFPCZ7Ei2oq8iQ= +github.com/asaskevich/govalidator v0.0.0-20210307081110-f21760c49a8d/go.mod h1:WaHUgvxTVq04UNunO+XhnAqY/wQc+bxr74GqbsZ/Jqw= github.com/aymerick/douceur v0.2.0 h1:Mv+mAeH1Q+n9Fr+oyamOlAkUNPWPlA8PPGR0QAaYuPk= github.com/aymerick/douceur v0.2.0/go.mod h1:wlT5vV2O3h55X9m7iVYN0TBM0NH/MmbLnd30/FjWUq4= github.com/gorilla/css v1.0.0 h1:BQqNyPTi50JCFMTw/b67hByjMVXZRwGha6wxVGkeihY= @@ -6,6 +8,8 @@ golang.org/x/net v0.0.0-20210421230115-4e50805a0758 h1:aEpZnXcAmXkd6AvLb2OPt+EN1 golang.org/x/net v0.0.0-20210421230115-4e50805a0758/go.mod h1:72T/g9IO56b78aLF+1Kcs5dz7/ng1VjMUvfKvpfy+jM= golang.org/x/net v0.0.0-20210610132358-84b48f89b13b h1:k+E048sYJHyVnsr1GDrRZWQ32D2C7lWs9JRc0bel53A= golang.org/x/net v0.0.0-20210610132358-84b48f89b13b/go.mod h1:9nx3DQGgdP8bBQD5qxJ1jj9UTztislL4KSBs9R2vV5Y= +golang.org/x/net v0.0.0-20210614182718-04defd469f4e h1:XpT3nA5TvE525Ne3hInMh6+GETgn27Zfm9dxsThnX2Q= +golang.org/x/net v0.0.0-20210614182718-04defd469f4e/go.mod h1:9nx3DQGgdP8bBQD5qxJ1jj9UTztislL4KSBs9R2vV5Y= golang.org/x/sys v0.0.0-20201119102817-f84b799fce68/go.mod h1:h1NjWce9XRLGQEsW7wpKNCjG9DtNlClVuFLEZdDNbEs= golang.org/x/sys v0.0.0-20210420072515-93ed5bcd2bfe/go.mod h1:h1NjWce9XRLGQEsW7wpKNCjG9DtNlClVuFLEZdDNbEs= golang.org/x/sys v0.0.0-20210423082822-04245dca01da/go.mod h1:h1NjWce9XRLGQEsW7wpKNCjG9DtNlClVuFLEZdDNbEs= diff --git a/vendor/github.com/microcosm-cc/bluemonday/sanitize.go b/vendor/github.com/microcosm-cc/bluemonday/sanitize.go index 9bb87a687..5f4b60d71 100644 --- a/vendor/github.com/microcosm-cc/bluemonday/sanitize.go +++ b/vendor/github.com/microcosm-cc/bluemonday/sanitize.go @@ -130,7 +130,7 @@ func escapeUrlComponent(w stringWriterWriter, val string) error { return err } -// Query represents a query +// Query represents a single part of the query string, a query param type Query struct { Key string Value string @@ -138,6 +138,10 @@ type Query struct { } func parseQuery(query string) (values []Query, err error) { + // This is essentially a copy of parseQuery from + // https://golang.org/src/net/url/url.go but adjusted to build our values + // based on our type, which we need to preserve the ordering of the query + // string for query != "" { key := query if i := strings.IndexAny(key, "&;");
