+ikiwiki-hosting assumes that the website uids' home directories will be created with at least a+x permissions. This was the default in Debian 12, but changes in shadow and/or util-linux in Debian unstable (I'm not sure which of these closely related packages is actually responsible) have resulted in the default becoming 0700, which doesn't allow `www-data` and `ikiwiki-anon` to read the web content and source git repo respectively.
+
+I think probably the way to solve this is to chmod the home directory to the permissions that ikiwiki-hosting expects; 0711 would probably be enough, but it doesn't seem like there's any real security benefit in denying the ability to list directory contents, because the contents of an ikiwiki-hosting website home directory are highly predictable anyway, and 0755 makes debugging easier.

+There is a [behaviour change in git 2.45.x](https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1076750) in which git-daemon(1) no longer allows exporting a git repo owned by a different uid unless the repository has been explicitly marked as safe.
+
+This resulted in [an automated test regression for ikiwiki-hosting](https://bugs.debian.org/1076751): the test asserts that we can `git clone` a newly created site's `source.git`, but the git-daemon(1) is running as `ikiwiki-anon` and the `source.git` is owned by `w-example`, so git-daemon(1) refuses to serve it.
+
+I've asked the git maintainers whether this particular behaviour change was intentional, and if yes, what the recommended way is to reassure git-daemon(1) that it can, in fact, serve another user's git repo. If the behaviour change was intentional, it might be necessary for `ikiwiki-hosting-web` to write out configuration to achieve that.
+
+A crude version is to write
+
+    [safe]
+    directory=*
+
+into `/var/lib/ikiwiki-hosting-web/git/.gitconfig`, but I'm hoping that the git maintainers can suggest something a little more targeted.

+The service file looks ok.
+
+I'm a bit unsure about the two ikiwiki-hosting.conf that don't get moved to
+the service file. If a user has changed those, they will have to notice the
+conffile change and follow through to edit the service file based on
+comments in the conffile.
+
+Also, ikisite uses those configs, so we lose DRY and the user has to
+remember to change a config in two places if they change it later. (To be
+fair, the postinst also creates a user based on those configs so changing
+them is already involved and probably noone actually does.)

+Wrapping an LSB init script with systemd-sysv-generator(8) is not an ideal way to run a system service. In particular, systemd-sysv-generator can't tell whether an init script is meant to be the equivalent of systemd Type=forking (like /etc/init.d/dbus) or the equivalent of systemd Type=oneshot (like /etc/init.d/sudo), so it has no choice but to create a weird mixture of the two which doesn't reliably detect errors.
+
+I suspect that a future version of systemd will deprecate systemd-sysv-generator and stop installing it by default, although I don't think any such plans have been announced yet.
+
+Here's a native systemd unit equivalent of the LSB init script, which is much shorter and simpler than the init script itself:

+## how to only enable ssl once a certificate is available
+
+Tip from [[Joey]]:
+
+Letsencrypt has a bit of a chicken and egg problem, in that the http server
+has to be up to get the certificate, but the apache site config file
+has to contain both the http and the https vhost. And the https vhost needs
+to point to cert files not available until letsencrypt has run.
+
+smcv was thinking about dealing with that by generating a temporary
+self-signed cert first. But, I don't like the possibility that a http site
+would come up with such a cert during normal operation.
+
+I found a way around this when adding letsencrypt support to propellor:
+Make the apache site config file contain only the http vhost, and use
+IncludeOptional to include another file which contains the https vhost.
+Generate that file only once letsencrypt has generated the cert.
+
+Note that IncludeOptional has to be used with a wildcard to avoid it being
+an error if the included file doesn't exist. So, something like:
+
+	IncludeOptional /etc/apache2/sites-available/$domain/*.conf

+It's important that any support includes automated certificate renewals.

+later handle renewal of itself, or by having ikiwiki-hosting take care of

+
+Also, there is rate limiting in the current beta (a few domains per IP or

+Subject: [PATCH] fix ssl redirections
+
+it seems the previous redirections were not doing anything, or more
+precisely, they were looping:
+
+    RewriteRule ^/(.*) <TMPL_VAR URL_ESCAPED> [L,R,NE]
+
+... was generting the following rule:
+
+    RewriteRule ^/(.*)  [L,R,NE]
+
+because url_escaped wasn't passed to the template. but even if was, it
+would still do an infinite redirect loop on itself. what it needs is
+https_url_escaped, which wasn't passed either.

+The workaround, of course, is to set `git-annex-shell` as the command in the `authorized_keys` file instead of `iki-git-shell`... but that doesn't quite work because the remote URLs change completely.
+
+So one solution is to exploit the `git-shell-commands` extension of `git-shell`, which allows running arbitrary commands from `git-shell`. Since `git-annex` starts with `git`, it will clear the `iki-git-shell` checks - but it fails in `git-shell` because it's not a recognized git command. To fix this, we need to add the following script in `$HOME/git-shell-commands/git-annex-shell`:
+
+<pre>
+#!/usr/bin/python
+
+import os
+import re
+import shlex
+import sys
+
+try:
+    # original command is like:
+    # "git-annex-shell 'configlist' '/'"
+    # argv is expected to be:
+    # ['git-shell-commands/git-annex-shell', '/home/.../source.git/']
+    # the last argument is the sanitized repo path from iki-git-shell
+    # so parse the original command string into an array safely
+    orig_argv = shlex.split(os.environ['SSH_ORIGINAL_COMMAND'])
+    # construct the command with the original command and the safe repo path
+    cmd = ['git-annex-shell', '-c', orig_argv[1], sys.argv[1]]
+    # if we have more arguments, shove them in (skipping unsafe path)
+    cmd += orig_argv[3:]
+    # restrict git-shell to known commands
+    os.environ['GIT_ANNEX_SHELL_LIMITED'] = 'true'
+    # restrict git-annex to the sanitized repository
+    os.environ['GIT_ANNEX_SHELL_DIRECTORY'] = sys.argv[1]
+    # keep all commands as readonly, disabled
+    #os.environ['GIT_ANNEX_SHELL_READONLY'] = 'true'
+    # split into that new command
+    os.execlp('git-annex-shell', *cmd)
+except Exception as e:
+    print "git-annex-shell wrapper improperly called: %s" % e
+</pre>
+
+This will not work out of the box with `iki-git-shell` because the C code garbles the `SSH_ORIG_COMMAND` with `strtok`. The following patch is also necessary to carry the command down below:
+
+<pre>

+        if (! s) {
+</pre>
+
+That way the tokenizer operates on a copy of the string instead of garbling the environment directly.
+
+Now, I know that:
+
+ 1. this is clunky
+ 2. it's python (heretic! burn! burn!)
+ 3. there's more comments than code (but I took a while to figure that stuff out, so better to share)
+ 4. it doesn't solve git-annex support in ikiwiki (ie. the objects won't get pushed to the source repo)
+ 5. it's 1h30AM on a friday
+
+But:
+
+ 1. it's a start!
+ 2. it works (ie. it will drop keys, share configs, etc)
+ 3. it should be fairly secure
+
+Your feedback would be greatly appreciated here. At the very least I think the patch on iki-git-shell can't hurt, unless hiding the original git command was deliberate. 
+
+Thanks! -- [[anarcat]]

+It would be great to support [git-annex](https://git-annex.branchable.com/) in ikiwiki-hosting. One of the things that would need to change would be the `iki-git-shell` command, which currently doesn't allow `git-annex-shell` to run, which breaks `git-annex`. I tried setting the `annex-shell` variable on the client side to `git annex-shell` to try to workaround the issue, but it still fails with:
