+Make sure extra source patches are downloaded, checksum-verified and applied
+when building.
+
+First we need a project that will have the patch applied:
+
+  $ mkdir needs-patch
+  $ cd needs-patch
+  $ git init --quiet
+  $ cat > dune-project <<EOF
+  > (lang dune 3.15)
+  > (name needs-patch)
+  > EOF
+  $ cat > needs-patch.opam <<EOF
+  > opam-version: "2.0"
+  > EOF
+  $ cat > dune <<EOF
+  > (library (public_name needs-patch) (name needs_patch))
+  > EOF
+  $ cat > needs_patch.ml <<EOF
+  > let msg = "Needs to be patched"
+  > EOF
+  $ cd ..
+  $ tar cf needs-patch.tar needs-patch
+  $ SRC_MD5=$(md5sum needs-patch.tar | cut -f1 -d' ')
+  $ cd needs-patch
+  $ git add -A
+  $ git commit -m "Initial" --quiet
+  $ cat > needs_patch.ml <<EOF
+  > let msg = "Patch successfully applied"
+  > EOF
+  $ git diff > ../required.patch
+  $ git add needs_patch.ml
+  $ git commit -m "First patch" --quiet
+  $ cat > needs_patch.ml <<EOF
+  > let msg = "Patch successfully applied, multiple times"
+  > EOF
+  $ git diff > ../additional.patch
+  $ cd ..
+  $ rm -rf needs-patch
+  $ REQUIRED_PATCH_MD5=$(md5sum required.patch | cut -f1 -d' ')
+  $ ADDITIONAL_PATCH_MD5=$(md5sum additional.patch | cut -f1 -d' ')
+
+Then we start the oneshot server for both the source and the patch.
+
+  $ echo needs-patch.tar > fake-curls
+  $ SRC_PORT=1
+  $ echo required.patch >> fake-curls
+  $ REQUIRED_PATCH_PORT=2
+
+We now have the checksums as well as the port numbers, so we can define the
+package.
+
+  $ mkrepo
+  $ mkpkg needs-patch 0.0.1 <<EOF
+  > build: ["dune" "build" "-p" name "-j" jobs]
+  > patches: ["required.patch"]
+  > url {

+  > }
+  > extra-source "required.patch" {
+  >   src: "http://localhost:$REQUIRED_PATCH_PORT"
+  >   checksum: "md5=$REQUIRED_PATCH_MD5"
+  > }
+  > EOF
+
+Now let's depend on that project with a binary that will display the message
+that is supposed to get patched.
+
+  $ cat > dune-project <<EOF
+  > (lang dune 3.15)
+  > (package (name my) (depends needs-patch))
+  > EOF
+  $ cat > dune <<EOF
+  > (executable (public_name display) (libraries needs-patch))
+  > EOF
+  $ cat > display.ml <<EOF
+  > let () = print_endline Needs_patch.msg
+  > EOF
+
+Lock the dependency, it should generate an a lock dir that references both the
+url and the extra source.
+
+  $ add_mock_repo_if_needed
+  $ dune pkg lock
+  Solution for dune.lock:
+  - needs-patch.0.0.1
+
+  $ sed -E 's/md5=[0-9a-f]+/md5=$HASH/g' dune.lock/needs-patch.pkg

+  (extra_sources
+   (required.patch
+    (fetch
+     (url http://localhost:2)
+     (checksum md5=$HASH))))
+
+Running the binary should download the tarball & patch, build them and show the
+correct, patched, message:
+
+  $ dune exec ./display.exe
+  Patch successfully applied
+
+Set up a new version of the package which has multiple `extra-sources`, the
+application order of them mattering:
+
+  $ echo needs-patch.tar >> fake-curls
+  $ SRC_PORT=3
+  $ echo required.patch >> fake-curls
+  $ REQUIRED_PATCH_PORT=4
+  $ echo additional.patch >> fake-curls
+  $ ADDITIONAL_PATCH_PORT=5
+
+  $ mkpkg needs-patch 0.0.2 <<EOF
+  > build: ["dune" "build" "-p" name "-j" jobs]

+  > EOF
+
+Lock the project to use that new package
+
+  $ dune pkg lock
+  Solution for dune.lock:
+  - needs-patch.0.0.2
+
+Running the binary should work and output the double patched message:
+
+  $ dune exec ./display.exe
+  Patch successfully applied, multiple times
