+title: "Mirroring git repositories with Gitea"
+date: 2024-06-27T10:05:46-04:00
+draft: true
+tags:
+    - gitea
+    - curl
+    - yq
+categories:
+    - development
+---
+
+[Gitea][1] is an awesome self hosted git forge. I use the [pull-mirror][2]
+feature to mirror many git repos (mostly from github). In this post, I want to
+share few maintenance scripts I ran that connects to [gitea-api][14] using
+[yq][] and [curl][].
+
+<!--more-->
+
+# TODO
+
+  * Change mirror interval
+  * Disable for mirror repos by default actions
+  * use jo https://github.com/jpmens/jo
+  * get just latest mirror and apply the settings
+
+## Setup
+
+### API token
+
+Go to `https://gitea.balki.me/user/settings/applications` and Generate new
+Token with write permission for repositories.
+
+# TODO
+set base url
+
+## Why Mirror?
+
+1. Remote sites may disappear one day.
+2. Better local code search. Github does not allow code search without signing
+   in.
+3. Tools like vim-plugins can use the local urls which is better for privacy.
+4. Setup notification when a repository creates a new tag.
+
+## Dumb crawlers problem
+
+My gitea [instance][3] is public and had all mirror repos public as well. This
+caused a huge network traffic from bots.
+
+I created an [organization][4] without public visibility and made it own all
+the mirror repos.
+
+```
+❯ yq --version
+yq (https://github.com/mikefarah/yq/) version v4.44.1
+
+❯ curl -V | head -c 11
+curl 8.8.0
+```
+
+## API token
+
+## Hooks for notification
+[Hooks][5]
+
+Lets first download the list of all mirror repos
+
+```bash
+TOKEN=d88446542e844f4da4ba75bbb85bd694a71907b5
+
+curl "https://gitea.balki.me/api/v1/repos/search?limit=100&mode=mirror" \
+	-H "accept: application/json" \
+	-H "Authorization: token $TOKEN" \
+	-o mirror-repos.json
+```
+
+References
+
+1. API doc: https://gitea.balki.me/api/swagger#/repository/repoSearch
+
+Create a [hook][5] manually in one repo and get the hook using the API
+
+```bash
+curl -s "https://gitea.balki.me/api/v1/repos/MirrorWatch/snac2/hooks?page=1&limit=10" \
+        -H "Authorization: token $TOKEN" | yq -P -oj
+```
+
+Sample Output:
+```json
+[
+  {
+    "id": 32,
+    "type": "telegram",
+    "branch_filter": "tag",
+    "config": {
+      "content_type": "json",
+      "url": "https://api.telegram.org/bot1169894068:J1JVbV3f2vEQpdnPqFANfhjWZrFuUCJs1EW/sendMessage?chat_id=-1008910751069"
+    },
+    "events": [
+      "create"
+    ],
+    "authorization_header": "",
+    "active": true,
+    "updated_at": "2024-06-20T20:54:33-04:00",
+    "created_at": "2024-06-20T20:54:33-04:00"
+  }
+]
+```
+
+Now loop through all mirror repos and add the same webook. Remove unwanted fields like `id`, `created_at`, etc.,
+
+```bash
+yq -r '.data[] | .full_name' mirror-repos.json | while read -r repo; do
+	echo "$repo"
+
+	curl "https://gitea.balki.me/api/v1/repos/$repo/hooks" \
+		-H "Authorization: token $TOKEN" \
+		--json @- <<-EOM
+			{
+				"active": true,
+				"branch_filter": "tag",
+				"config": {
+					"content_type": "json",
+					"url": "https://api.telegram.org/bot1169894068:J1JVbV3f2vEQpdnPqFANfhjWZrFuUCJs1EW/sendMessage?chat_id=-1008910751069"
+                },
+				"events": [
+					"create"
+				],
+				"type": "telegram"
+			}
+		EOM
+
+	echo "============"
+done
+```
+
+## Fixing issues and pr links
+
+Fix the issue url setting in first repo as shown [here][7].
+
+Get the json representataion.
+
+```bash
+yq '.data[] | .external_tracker ' mirror-repos.json | head
+```
+
+Sample output
+
+```json
+{
+  "external_tracker_url": "https://github.com/caddyserver/caddy/issues",
+  "external_tracker_format": "https://github.com/caddyserver/caddy/issues/{index}",
+  "external_tracker_style": "numeric",
+  "external_tracker_regexp_pattern": ""
+}
+```
+
+Now loop throug all repos and update. Making sure only add to github repos and
+they are not already updated
+
+```bash
+yq -r '.data[]
+| select(.original_url == "*github*" and has("internal_tracker") )
+| "\(.full_name) \(.original_url)"' mirror-repos.json | while read -r repo og; do
+	echo "Repo is $repo and github origin url is $og"
+	curl "https://gitea.balki.me/api/v1/repos/$repo" \
+		-H "Authorization: token $TOKEN" \
+		-X PATCH \
+		--json @- <<-EOM
+			{
+					"external_tracker": {
+					"external_tracker_url": "${og%.git}/issues",
+					"external_tracker_format": "${og%.git}/issues/{index}",
+					"external_tracker_style": "numeric",
+					"external_tracker_regexp_pattern": ""
+					}
+			}
+		EOM
+done
+yq -r '.data[] | .full_name' mirror-repos.json | while read -r repo; do
+	echo "$repo"
+	jo has_actions=false | curl "https://gitea.balki.me/api/v1/repos/$repo" \
+		-H "Authorization: token $TOKEN" \
+		-X PATCH \
+		--json @-

+date: 2024-04-19T17:31:06-04:00
+tags:
+    - unix-sockets
+    - tmpfiles.d
+    - webserver
+categories:
+    - sysadmin
+---
+
+Webapps usually listen on a random tcp port and a web server forwards the
+requests to it. Webserver handles tls, static asset serving and sometimes
+authentication, bruteforce check etc., However any local user in the system can
+directly connect to the app's listen port bypassing the web server and thus
+loose the protections offered by the webserver.
+
+### Unix sockets
+
+Unix sockets are special files in filesystem that processes can use to
+communicate instead of tcp ports. Since they are files, filesytem ownership and
+permissions can be used to restrict which system-users can listen or connect to
+them
+
+### Caddy ↔ Gitea
+
+I use [Caddy][1] web server which reverse-proxies to [Gitea][2] server. For
+caddy to connect to gitea and also disallow anyother user to connect, we want a
+socket like below
+
+```bash
+srw-rw---- 1 gitea caddy 0 Apr 17 21:24 /run/gitea.sock
+```
+
+Unfortunately neither `user caddy` nor `user gitea`, can create such socket.
+Regular users can only create files owned by themselves. Only root can
+create/change ownership of files and folders.
+
+### `tmpfiles.d` to rescue
+
+[tmpfiles.d][3] provides a way to do it. Since it is run as root, it can create
+files and directories as any user.
+
+```bash
+❯ cat /etc/tmpfiles.d/caddy-run-unix.conf
+d /run/gitea-caddy 0750 gitea caddy -
+```
+Above config creates below directory every time on startup.
+
+```bash
+❯ sudo ls -ld /run/gitea-caddy/
+drwxr-x--- 2 gitea caddy 60 Apr 17 21:24 /run/gitea-caddy/
+```
+
+With those permissions and ownership, only `user gitea` can create the socket
+in `/run/gitea-caddy` and only `user caddy` can `cd` into that directory.
+
+```bash
+❯ sudo ls -l /run/gitea-caddy/web.sock
+srw-rw-rw- 1 gitea gitea 0 Apr 17 21:24 /run/gitea-caddy/web.sock
+```
+
+The socket file permission can be more liberal as no other user can read into
+the `/run/gitea-caddy` directory
+
+### Bonus!
+
+If your app does not connect to any external services, it can even be run in a
+[private network][4].
