1 f3a795ae 2021-08-03 op It took me a while to release this 1.6 version compared to the previous ones, but we’re finally here!
3 f3a795ae 2021-08-03 op The headlines for this version are an improved CGI implementation and performance, but you’ll find the full changelog at the end of this entry.
5 f3a795ae 2021-08-03 op libevent is now a dependency of gmid: the new event-loop should be faster than the old poll(2)-based one.
7 f3a795ae 2021-08-03 op Thanks to a clear design and privilege-separation, it was easy to spawn multiple server processes: this increases the performance and prevents delays. Three server processes are run by default, but the actual number it’s tunable via the new global ‘prefork’ option.
9 f3a795ae 2021-08-03 op The configuration file was enriched also with some other additions:
10 f3a795ae 2021-08-03 op * ‘block return’ and ‘strip’ allows to define dynamic redirects and/or error pages
11 f3a795ae 2021-08-03 op * ‘entrypoint’ forwards every request for a virtual host to a CGI script
12 f3a795ae 2021-08-03 op * ‘log’ allows to control logging per virtual host
13 f3a795ae 2021-08-03 op * ‘require client ca’ allows to restrict part of a virtual-host only to clients that provides a certificate signed by a specific CA
15 f3a795ae 2021-08-03 op Unfortunately, there are also a couple of breaking changes. I had to change the CGI environment variables so they match the CGI specification. The good news is that now CGI scripts are a bit more portable and that these breaking changes were done early in this release cycle, so if you started using gmid after the 1.5 release chances are that you’re already using these new variables.
17 f3a795ae 2021-08-03 op In particular:
18 f3a795ae 2021-08-03 op * QUERY_STRING is always percent-encoded
19 f3a795ae 2021-08-03 op * PATH_INFO and PATH_TRANSLATED always starts with a forward slash (/)
20 f3a795ae 2021-08-03 op * some variables have been renamed.
22 f3a795ae 2021-08-03 op I set up a testing page that shows the various variables:
