Summary0005015: set::allow-userhost-change force-rejoin not working
DescriptionFirst of all thank you very much for viewing my issue 0005012 and taking it into consideration. I was not aware of the set::allow-userhost-change force-rejoin option and implemented it, yet it appears to be a bit buggy: when someone has been assigned a vhost via HostServ and uses /hs off to turn it off, when user mode +x is reset, the cycling of channels is NOT performed; only when the vhost is enabled.
This behaviour does not seem to be intended, and this is with the default UnrealIRCd cloaking module.
Steps To ReproduceThe UnrealIRCd version is 4.0.13 and the services utilized are Anope IRC Services version 2.0.5
TagsNo tags attached.

I'll take a look. Sounds easy to reproduce :)
Probably an oversight in the source code somewhere. Funny nobody mentioned it before.

Thanks for the bug report.

I ended up doing this in a big commit:

commit 5124e60b7cd12da3d0d261b671c0a55b2bbc5f05
Author: Bram Matthys <>

    Add "CAP chghost" support. Internal recode of userhost changes.
    Fix force-rejoin not working if doing SVSMODE -x/+x (Koragg, 0005015).
    Note to module coders:
    Please use the following procedure in case of an user/host change:
    * userhost_save_current(acptr);
    * << change username or hostname here (or both) >>
    * userhost_changed(acptr);
    This function will take care of notifying other clients about
    the userhost change, such as doing PART+JOIN+MODE if force-rejoin
    is enabled, and sending :xx CHGHOST user host messages to
    "CAP chghost" capable clients.
    Also, small note to everyone:
    If force-rejoin is enabled we will not send the PART+JOIN+MODE to
    "CAP chghost" capable clients. Doing so is just a hack to notify
    people of a userhost change. "CAP chghost" users can thus benefit
    from the reduced noise in this respect.

Also, if you find any other places where we are missing host change notification, then do let me know. I think they are all covered (and there were many) but it's always possible to miss one.
