It could lead to `fetchGit` not accepting valid branch names, even though they exist in a repository (for example, branch names containing `/`, which are pretty standard, like `release/1.0` branches). The new regex defines what a branch name should **NOT** contain. It takes the definitions from `refs.c` in https://github.com/git/git and `git help check-ref-format` pages. This change also introduces a test for ref name validity checking, which compares the result from Nix with the result of `git check-ref-format --branch`. --- src/libfetchers/git.cc | 2 +- src/libutil/url.cc | 1 + src/libutil/url.hh | 6 +++ tests/fetchGitRefs.sh | 111 +++++++++++++++++++++++++++++++++++++++++ tests/local.mk | 1 + 5 files changed, 120 insertions(+), 1 deletion(-) create mode 100644 tests/fetchGitRefs.sh diff --git a/src/libfetchers/git.cc b/src/libfetchers/git.cc index 17cc60228..e069057eb 100644 --- a/src/libfetchers/git.cc +++ b/src/libfetchers/git.cc @@ -418,7 +418,7 @@ struct GitInputScheme : InputScheme auto input = std::make_unique(parseURL(getStrAttr(attrs, "url"))); if (auto ref = maybeGetStrAttr(attrs, "ref")) { - if (!std::regex_match(*ref, refRegex)) + if (std::regex_search(*ref, badGitRefRegex)) throw BadURL("invalid Git branch/tag name '%s'", *ref); input->ref = *ref; } diff --git a/src/libutil/url.cc b/src/libutil/url.cc index 5d5328e5d..88c09eef9 100644 --- a/src/libutil/url.cc +++ b/src/libutil/url.cc @@ -4,6 +4,7 @@ namespace nix { std::regex refRegex(refRegexS, std::regex::ECMAScript); +std::regex badGitRefRegex(badGitRefRegexS, std::regex::ECMAScript); std::regex revRegex(revRegexS, std::regex::ECMAScript); std::regex flakeIdRegex(flakeIdRegexS, std::regex::ECMAScript); diff --git a/src/libutil/url.hh b/src/libutil/url.hh index 1503023a2..4a0d4071b 100644 --- a/src/libutil/url.hh +++ b/src/libutil/url.hh @@ -49,6 +49,12 @@ const static std::string pathRegex = "(?:" + segmentRegex + "(?:/" + segmentRege const static std::string refRegexS = "[a-zA-Z0-9][a-zA-Z0-9_.-]*"; // FIXME: check extern std::regex refRegex; +// Instead of defining what a good Git Ref is, we define what a bad Git Ref is +// This is because of the definition of a ref in refs.c in https://github.com/git/git +// See tests/fetchGitRefs.sh for the full definition +const static std::string badGitRefRegexS = "//|^[./]|/\\.|\\.\\.|[[:cntrl:][:space:]:?^~\[]|\\\\|\\*|\\.lock$|\\.lock/|@\\{|[/.]$|^@$|^$"; +extern std::regex badGitRefRegex; + // A Git revision (a SHA-1 commit hash). const static std::string revRegexS = "[0-9a-fA-F]{40}"; extern std::regex revRegex; diff --git a/tests/fetchGitRefs.sh b/tests/fetchGitRefs.sh new file mode 100644 index 000000000..93993ae90 --- /dev/null +++ b/tests/fetchGitRefs.sh @@ -0,0 +1,111 @@ +source common.sh + +if [[ -z $(type -p git) ]]; then + echo "Git not installed; skipping Git tests" + exit 99 +fi + +clearStore + +repo="$TEST_ROOT/git" + +rm -rf "$repo" "${repo}-tmp" "$TEST_HOME/.cache/nix" + +git init "$repo" +git -C "$repo" config user.email "foobar@example.com" +git -C "$repo" config user.name "Foobar" + +echo utrecht > "$repo"/hello +git -C "$repo" add hello +git -C "$repo" commit -m 'Bla1' + +path=$(nix eval --raw "(builtins.fetchGit { url = $repo; ref = \"master\"; }).outPath") + +# Test various combinations of ref names +# (taken from the git project) + +# git help check-ref-format +# Git imposes the following rules on how references are named: +# +# 1.
