The manual pages on man.netbsd.org are rendered by man-cgi, a ~1400-line POSIX shell script forked per request by fcgiwrap behind an nginx FastCGI cache and Fastly. This weekend I overhauled how the service caches. (more…)

Upstream released sesh 2.27.0 while misc/sesh was still at 2.26.1. I added the package earlier this year, but this was the first time I upgraded a package written in Go, so I made some notes about the Go-specific steps. The general pkgsrc update procedure applies as usual; the new part is go-modules.mk, the file listing all the Go module distfiles fetched from the module proxy. (more…)

WordPress Site Health had been nagging me to use a persistent object cache. I already run Zend OpCache, so I wondered what else I needed.

OpCache is an opcode cache: it stores the compiled bytecode of the PHP source so the engine need not recompile it on every request. The object cache is a different layer, holding the results of database queries and transients. WordPress ships with a non-persistent object cache that lives only for the duration of a single request; making it persistent means backing it with something that survives across requests, such as Redis.

On this site I manage the WordPress tree with svn and do not let PHP write into it, which changes a couple of the steps from the usual click-in-the-dashboard instructions. While I also generally prefer nginx and PHP-FPM, this site is still on Apache with mod_php. However, the installation is basically the same regardless of the web server software, but troubleshooting differs between them. I’m covering both here. (more…)

If you find yourself with an old Terraform state file (say from v0.11) and you need to run terraform plan to check things out, you’ll need to make some adjustments:

• Add a terraform block with required_providers to provide the source for the provider.
• Remove the version statement from the provider block. (You will want to move it to the provider in the required_providers block.)
• Adjust any other syntax changes that result in errors (terraform plan):
  • list() → tolist([])
  • type = "string" → type = string
  • Possibly many others…
• Replace the provider in the existing ancient state file.
• Refresh the providers (terraform init).
• Plan away! (more…)

I am pleased to announce that tcsh-6.23 is now available; this is mainly a bug fix release (after 2 years) with a couple of new features:

1. Add jobs -Z to setproctitle(3)
2. Add ln=target in LS_COLORS
3. Add a :Q modifier that preserves empty arguments

Please consult the Fixes file for a complete list of changes. (more…)

For seven years I’ve maintained a small patch to PHP Markdown Extra. However, the upstream was not happy with it, so I just kept my local copy patched. Now I’ve given in: as Markdown has become very popular, it has been better to just adopt a syntax that works across different implementations (e.g. with GitHub Flavored Markdown). (more…)
