Last last night, after renaming some buildlists, which were actually setnames, for poudriere, I realized that files in /usr/local/etc/poudriere.d also needed to be renamed.

In this post:

  • poudriere 3.3.7
  • nginx 1.20.1_2,2
  • Both running on FreeBSD 13.0-RELEASE-p4

These are my renamed files:

[dan@pkg01:/usr/local/etc/poudriere.d]: $ ls *primary*
primary-make.conf          primary-poudriere.conf     primaryi386-make.conf      primaryi386-poudriere.conf

The output of svn status illustrates the changes I made:

[dan@pkg01:/usr/local/etc/poudriere.d]: $ svn st
D       master-list-i386-make.conf
        > moved to primaryi386-make.conf
D       master-list-i386-poudriere.conf
        > moved to primaryi386-poudriere.confa
D       master-list-make.conf
        > moved to primary-make.conf
D       master-list-poudriere.conf
        > moved to primary-poudriere.conf
M       ports/default/timestamp
M       ports/dvl-git/mnt
M       ports/testing/timestamp
A  +    primary-make.conf
        > moved from master-list-make.conf
A  +    primary-poudriere.conf
        > moved from master-list-poudriere.conf
A  +    primaryi386-make.conf
        > moved from master-list-i386-make.conf
A  +    primaryi386-poudriere.confa
        > moved from master-list-i386-poudriere.conf

Next, I’ll do the Nginx aliases.

Nginx Aliases

These are the old directories for which I want aliases:

drwxr-xr-x  3 root  wheel  11 May 23 21:33 13i386-default-master-list-i38686
[dan@pkg01:/usr/local/poudriere/data/packages]: $ ls -ld *master-list* | egrep -e '122|13'
drwxr-xr-x  3 root  wheel  13 Aug 28 04:18 122amd64-default-master-list
drwxr-xr-x  4 root  wheel  14 Aug 11 08:36 122amd64-dvl-master-list
drwxr-xr-x  3 root  wheel  13 Aug 28 04:22 122i386-default-master-list-i386
drwxr-xr-x  3 root  wheel  13 Aug 28 04:22 13amd64-default-master-list
drwxr-xr-x  3 root  wheel  13 Aug  8 16:13 13amd64-dvl-master-list
drwxr-xr-x  4 root  wheel   5 Aug 27 16:55 13i386-default-master-list
drwxr-xr-x  3 root  wheel  13 Aug 28 04:26 13i386-default-master-list-i386
drwxr-xr-x  3 root  wheel  11 May 23 21:33 13i386-default-master-list-i38686

These are what they will be aliased to:

[dan@pkg01:/usr/local/poudriere/data/packages]: $ ls -ld *primary*
drwxr-xr-x  3 root  wheel  13 Aug 29 05:20 122amd64-default-primary
drwxr-xr-x  3 root  wheel  13 Aug 29 06:37 122i386-default-primaryi386
drwxr-xr-x  3 root  wheel  13 Aug 29 08:38 13amd64-default-primary
drwxr-xr-x  3 root  wheel  13 Aug 29 10:14 13i386-default-primaryi386

Not everything will be aliased:

  1. 13i386-default-master-list-i38686 is a typo – I put one too many 86’s in the build name
  2. Anything containing dvl is me running testport

The configuration file at /usr/local/etc/nginx/nginx.conf already contains:

        location /packages {
            root      /usr/local/poudriere/data;
            autoindex on;
            index     index.html index.htm;
        }

Let’s start with this host for testing:

[dan@empty:~] $ pkg -vv | grep url
    url             : "pkg+http://fedex.int.unixathome.org/packages/13amd64-default-master-list/",

For testing, I first created this file:

[dan@pkg01:/usr/local/poudriere/data/packages]: $ sudo touch 13amd64-default-master-list/THINGS

Then browsed to the above mentioned URL and saw the empty file THINGS listed there. OK, this proves I’m looking at the old data.

Next, I added an alias, which failed. I’ll explain why later.

        location /packages/13amd64-default-master-list {
            alias /packages/13amd64-default-primary;
        }

That gives a 404:

2001:470:8abf:[redacted] - - [29/Aug/2021:16:35:03 +0000] "GET /packages/13amd64-default-master-list/ HTTP/1.1" 404 153 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/14.1.2 Safari/605.1.15"

Why? The target of the alias should be a directory, not a URL. Let’s try this instead:

Let’s try this instead:

        location /packages/13amd64-default-master-list {
            alias /usr/local/poudriere/data/packages/13amd64-default-primary;
        }

That is an improvement, but gives a Forbidden.

Let’s try this, just like /packages above.

        location /packages/13amd64-default-master-list {
            alias /usr/local/poudriere/data/packages/13amd64-default-primary;
            autoindex on;
            index     index.html index.htm;
        }

That works, and as shown by the screen shot, there is no THINGS file, so I know I’m in the right place.

NOTE: I’ll go back and delete that file later.

Rewrite may be better

I think rewrite is better than alias for this situation.

Let’s try it:

Based on the documentation, I’ll try this:

        # master-list became primary - to help poudriere with hyphens in set
        # names - see https://dan.langille.org/2021/08/28/poudriere-warning-using-in-a-setname-is-not-recommended-as-it-causes-ambiguities-with-parsing-the-build-name-of-122amd64-default-master-list/
        rewrite ^(/packages/.*)master-list/(.*)$ $1primary/$2 last;
        rewrite ^(/packages/.*)master-list-i386/(.*)$ $1primaryi386/$2 last;

That is much cleaner and replaces the entire location directive I was using.

Further testing

For more testing, I created WRONG files in the old directories:

[dan@pkg01:/usr/local/poudriere/data/packages]: $ sudo touch 122amd64-default-master-list/WRONG
[dan@pkg01:/usr/local/poudriere/data/packages]: $ sudo touch 122i386-default-master-list-i386/WRONG
[dan@pkg01:/usr/local/poudriere/data/packages]: $ sudo touch 13amd64-default-master-list/WRONG
[dan@pkg01:/usr/local/poudriere/data/packages]: $ sudo touch 13i386-default-master-list/WRONG
[dan@pkg01:/usr/local/poudriere/data/packages]: $ sudo touch 13i386-default-master-list-i386/WRONG

NOTE: 13i386-default-master-list is wrong by definition. It should never be built. It should always be: 13i386-default-master-list-i386 with the trailing -i386. That is my naming convention.

There is nothing in there but my file:

[dan@pkg01:/usr/local/poudriere/data/packages]: $ ls -l 13i386-default-master-list
total 1
-rw-r--r--  1 root  wheel  0 Aug 29 16:50 WRONG
[dan@pkg01:/usr/local/poudriere/data/packages]: $ ls -dl 13i386-default-master-list
drwxr-xr-x  4 root  wheel  6 Aug 29 16:50 13i386-default-master-list
[dan@pkg01:/usr/local/poudriere/data/packages]: $ 

I suspect a failed build, halted when I realized my error. I’m removing it:

[dan@pkg01:/usr/local/poudriere/data/packages]: $ sudo rm -rf 13i386-default-master-list
[dan@pkg01:/usr/local/poudriere/data/packages]: $ 

When I commented out those rewrite statements, restarted nginx and browsed to all those URLs, I saw WRONG listed.

Conclusion: the rewrite work. I’m keeping them.

EDIT: 2021-09-04 – still working well. Success.
