When compiling got-portable from source, outside of an official release tarball, it's often helpful to know which commit the binary was built from, especially for diagnostic purposes. This adds an extra hook to AC_INIT to derive whether -portable is being built in-tree or via a release tarball.

Compiling -portable on MacOS directly would never have worked, as the environment was only being set when run under CI. Move these checks into configure.ac so that they propagate out to make, etc. Noticed by cjones on IRC.

Remove dependency on libretls as TLS isn't going to be included in gotwebd any time soon. This reverts commit af7f5027866eea7b4299c2319f83d0eb18a395e6.

This isn't defined on all systems.

This is needed for gotwebd.

This is not yet "clean", but does compile. A few things to consider: * See comments beginning with "TA:"

Don't assert compat/queue.h in favour of what's on the system. When -portable was first being developed, there were frequent clashes between libbsd, and the check for sys/queue.h got lost in that noise. Noticed by stsp@

Bump the version in git now to the next version. Over time, this should really use the SHA1 to indicate a non-released build.

Siphash is being used in place of murmurhash for object-id set as this is faster. However, this isn't really seen much in the non-BSD userspace, so provide an implementation for it portably, if one isn't found.

Update CHANGELOG and configure.ac for the 0.68.1 release

Update CHANGELOG and configure.ac for the -portable 0.68 release.

Allow the libexec helper, `got-read-patch` to be compiled, portably.

This adds support for DragonFlyBSD.

Rather than making certain checks for panelw dependant on the underlying operating system, actually use pkg-config's detection mechanism properly. This makes the checking for panelw much easier and broader for other OSes which might have either panelw or gnupanelw.

This adds support for NetBSD, using the following external dependencies: libuuid ncursesw There is no CI (yet) as enabling that on Cirrus-CI requires some work, so for now, these builds will be run manually before releases. The test suite will also need tweaking to be fully supported but the key tests are supported for now.

This adds support for MacOS (Monteray onward, although should work on older MacOSes). The BSD wrapper for poll/ppoll has been lifted from the work the folks over at OpenSSH have done -- thanks!
