propellor/src/Propellor/Property/Hostname.hs, branch master

Removed dependency on MissingH, instead depends on split and hashable.

2017-05-16T00:09:31Z

MissingH is a heavy dependency, which pulls in parsec and a bunch of stuff. So eliminating it makes propellor easier to install and less likely to fail to build. changesFileContent now uses hashable's hash. This may not be stable across upgrades, I'm not sure -- but it's surely ok here, as the hash is not stored. socketFile also uses hash. I *think* this is ok, even if it's not stable. If it's not stable, an upgrade might make propellor hash a hostname to a different number, but with 9 digets of number in use, the chances of a collision are small. In any case, I've opned a bug report asking for the stability to be documented, and I think it's intended to be stable, only the documentation is bad. NB: I have not checked that the arch linux and freebsd packages for the new deps, that Propellor.Bootstrap lists, are the right names or even exist. Since propellor depends on hashable, it could be changed to use unordered-containers, rather than containers, which would be faster and perhaps less deps too.

Also, implemented modifyHostProps to add properties to an existing host. Using it bypasses some type safety. Its use in docker is safe though. But, in Conductor, the use of it was not really safe, because it was used with a DebianLike property. Fixed that by making Ssh.installed target all unix's, although it will fail on non-DebianLike ones.

UncheckedProperty for cmdProperty et al

2015-12-05T21:53:16Z

* Properties that run an arbitrary command, such as cmdProperty and scriptProperty are converted to use UncheckedProperty, since they cannot tell on their own if the command truely made a change or not. (API Change) Transition guide: - When GHC complains about an UncheckedProperty, add: `assume` MadeChange - Since these properties used to always return MadeChange, that change is always safe to make. - Or, if you know that the command should modifiy a file, use: `changesFile` filename * A few properties have had their Result improved, for example Apt.buldDep and Apt.autoRemove now check if a change was made or not.

Hostname.sane and Hostname.setTo can now safely be used as a property of a chroot, and won't affect the hostname of the host system.

GADT properties seem to work (untested)

2015-01-25T02:38:51Z

* Property has been converted to a GADT, and will be Property NoInfo or Property HasInfo. This was done to make sure that ensureProperty is only used on properties that do not have Info. Transition guide: - Change all "Property" to "Property NoInfo" or "Property WithInfo" (The compiler can tell you if you got it wrong!) - To construct a RevertableProperty, it is useful to use the new () operator - Constructing a list of properties can be problimatic, since Property NoInto and Property WithInfo are different types and cannot appear in the same list. To deal with this, "props" has been added, and can built up a list of properties of different types, using the same (&) and (!) operators that are used to build up a host's properties.
