This post shows how I used a git spare checkout to build vuxml files without having the whole ports tree present.
In this post:
- FreeBSD 14.2
- FreeBSD 14.3-STABLE
- git-2.50.1
- git-tiny-2.50.1
This came about when recent commits to security/vuxml weren’t showing up on in my host, despite doing pkg audit -f – this was several hours after the commit.
trouble told me to check this jail on that host. Eventually I figured out the problem was a Makefile target of vuln.xml – I suspect the problem is related to that file being split up into multiple files. Let’s use a different ..
and as I type this, I realize this idea won’t work.
I was going to run make vuln-flat.xml – and generate a new flat file.
That new flat file will always have a recent build date, which will build new files and ship them out.
No, I think I’ll have to take a different approach.
But I still want that sparse checkout.
Let’s try this:
[dvl@freefall ~/vuxmlbuild]$ git clone --filter=tree:0 --no-checkout --depth 1 https://git.FreeBSD.org/ports.git vuxml-git Cloning into 'vuxml-git'... remote: Enumerating objects: 1, done. remote: Counting objects: 100% (1/1), done. remote: Total 1 (delta 0), reused 0 (delta 0), pack-reused 0 (from 0) Receiving objects: 100% (1/1), done.

[dvl@freefall ~/vuxmlbuild/vuxml-git]$ ls -l security/vuxml/ total 62 -rw-r--r-- 1 dvl dvl 3672 Aug 1 19:56 Makefile -rw-r--r-- 1 dvl dvl 901 Aug 1 19:56 distinfo drwxr-xr-x 2 dvl dvl 9 Aug 1 19:56 files -rw-r--r-- 1 dvl dvl 267 Aug 1 19:56 pkg-descr -rw-r--r-- 1 dvl dvl 255 Aug 1 19:56 pkg-plist drwxr-xr-x 2 dvl dvl 25 Aug 1 19:56 vuln -rw-r--r-- 1 dvl dvl 4124 Aug 1 19:56 vuln.xml [dvl@freefall ~/vuxmlbuild/vuxml-git]$
Done. Just what I need for this test.
After a bit of testing, I found I needed this command:
[dvl@freefall ~/vuxmlbuild/vuxml-git]$ git sparse-checkout set path Mk security/vuxml lang/python311 ports-mgmt/pkg textproc/xmlcatmgr textproc/libxslt textproc/xhtml-modularization textproc/xhtml-basic
With that, I could do this:
[dvl@freefall ~/vuxmlbuild/vuxml-git/security/vuxml]$ make vuln-flat.xml xmllint -noent /home/dvl/src/vuxmlbuild/vuxml-git/security/vuxml/vuln.xml > vuln-flat.xml [dvl@freefall ~/vuxmlbuild/vuxml-git/security/vuxml]$ git status On branch main Your branch is up to date with 'origin/main'. You are in a sparse checkout with 1% of tracked files present. nothing to commit, working tree clean [dvl@freefall ~/vuxmlbuild/vuxml-git/security/vuxml]$ ls -l total 3138 -rw-r--r-- 1 dvl dvl 3672 Aug 1 20:16 Makefile -rw-r--r-- 1 dvl dvl 901 Aug 1 20:16 distinfo drwxr-xr-x 2 dvl dvl 9 Aug 1 20:16 files -rw-r--r-- 1 dvl dvl 267 Aug 1 20:16 pkg-descr -rw-r--r-- 1 dvl dvl 255 Aug 1 20:16 pkg-plist drwxr-xr-x 2 dvl dvl 25 Aug 1 20:16 vuln -rw-r--r-- 1 dvl dvl 8782882 Aug 1 20:18 vuln-flat.xml -rw-r--r-- 1 dvl dvl 4124 Aug 1 20:16 vuln.xml
Running the command again, without changes to files, yields no changes:
[dvl@freefall ~/vuxmlbuild/vuxml-git/security/vuxml]$ make vuln-flat.xml `vuln-flat.xml' is up to date. [dvl@freefall ~/vuxmlbuild/vuxml-git/security/vuxml]$ ls -l total 3138 -rw-r--r-- 1 dvl dvl 3672 Aug 1 20:16 Makefile -rw-r--r-- 1 dvl dvl 901 Aug 1 20:16 distinfo drwxr-xr-x 2 dvl dvl 9 Aug 1 20:16 files -rw-r--r-- 1 dvl dvl 267 Aug 1 20:16 pkg-descr -rw-r--r-- 1 dvl dvl 255 Aug 1 20:16 pkg-plist drwxr-xr-x 2 dvl dvl 25 Aug 1 20:16 vuln -rw-r--r-- 1 dvl dvl 8782882 Aug 1 20:18 vuln-flat.xml -rw-r--r-- 1 dvl dvl 4124 Aug 1 20:16 vuln.xml
Touching one of the file, altering the date, gives us a new file:
[dvl@freefall ~/vuxmlbuild/vuxml-git/security/vuxml]$ touch vuln/2025.xml [dvl@freefall ~/vuxmlbuild/vuxml-git/security/vuxml]$ make vuln-flat.xml xmllint -noent /home/dvl/src/vuxmlbuild/vuxml-git/security/vuxml/vuln.xml > vuln-flat.xml [dvl@freefall ~/vuxmlbuild/vuxml-git/security/vuxml]$ ls -l total 3138 -rw-r--r-- 1 dvl dvl 3672 Aug 1 20:16 Makefile -rw-r--r-- 1 dvl dvl 901 Aug 1 20:16 distinfo drwxr-xr-x 2 dvl dvl 9 Aug 1 20:16 files -rw-r--r-- 1 dvl dvl 267 Aug 1 20:16 pkg-descr -rw-r--r-- 1 dvl dvl 255 Aug 1 20:16 pkg-plist drwxr-xr-x 2 dvl dvl 25 Aug 1 20:16 vuln -rw-r--r-- 1 dvl dvl 8782882 Aug 1 20:20 vuln-flat.xml -rw-r--r-- 1 dvl dvl 4124 Aug 1 20:16 vuln.xml [dvl@freefall ~/vuxmlbuild/vuxml-git/security/vuxml]$
I think we can use this for distributing the vuxml database files.
