This branch of a2server only supports jessie and above, either Raspbian
or Debian. While I was at it, I simplified the tests for what is and is
not a supported OS. If there are bad kernels or firmwares we need to
work around those should be fixes. This also means giving the user an
option to interrupt the installation if they are trying to install on a
Debian(ish) system that is too old or (more likely) too new.
At least ivan.sh is now using a2cloud's system_ident script.
- Added bash check to install.sh
- Switched to using top_src instead of a2sSource (not yet in ivan.sh
subscripts)
- Added processing of -y and -c flags to install.sh ala a2cloud
- Put the intro blurb and continue question in install.sh (didn't remove
the one from ivan.sh yet as it serves as a useful way to test things
about to be in progress and stop after them…)
- Added the fixup script, currently empty for a2server, but ohh will
that be changing!
- Added the show_changes script. It doesn't do a whole lot for a2server
just like it doesn't for a2cloud yet. To be addressed. Higher
priorities right now.
- Fixed a bug where fresh installs would say that upgrading from your
version of a2server wasn't supported anymore.
We need a more robust way to detect whether netatalk is installed or
needs to be installed, the current check by a2server version isn't very
reliable anyway, assuming that netatalk will always be hand-compiled and
never upgraded. But for now at least, let's fix my idiot mistake.
Legacy code in the remaining scripts to have them run from the website
using a2sDevel detection has been purged. That doesn't mean everything
now runs locally always—that's going to require a finer pick through the
code I haven't done yet. This is a start though, and doing it found a
couple of bugs I've managed to fix already.
New standalone script for comparing two #.#.# format version strings
using standard functions included with python. We also benefit from the
fact the python function is more flexible than my bash function and it
keeps the logic of a rather high-level script high-level.
Ivan added support to build everything on Debian/Raspbian stretch, added
some alternate URLs, and updated the "just how the hell do you install
Marinetti right now exactly?" dance.
This was more frustrating to merge than it honestly should've been and
I'm kinda responsible for some of that, but it's never gonna get easier
to maintain unless we break from the single-developer monolithic blocks.
Hopefully this will be the last time we do things this way.
suppress null byte read warnings in Bash 4.4
enable SSH server on Raspberry Pi if disabled
Internet Archive backup URL's for external downloads, where possible
compiles AppleTalk kernel if -c flag is specified, rather than downloading
better cleanup after AppleTalk kernel compile
notification if AppleTalk kernel module doesn't load
fixed download links for communication software
fixed bugs possibly preventing compile of macipgw and ciopfs
fixed minor bugs during initial setup prompts
os option (Raspbian update) removed from a2server-setup
A2SERVER's setup no longer takes the -os or os arguments (the security
paradigm shift suggests this is unnecessary and even unwise), and it's
time to actually install the debupdate script.
Still need to polish this a bit, but I think I'm happy with its
functionality. This will replace raspbian-update. It's simpler, more
transparent about what it is doing, and generally less likely to go
wrong doing what it does.
The one little bit of magic is that it bails out after an update if
there's nothing to install, mostly to avoid suggesting that you reboot
your system if there is nothing to install. Might not be worth it for
that on armv6-based Raspberry Pis.
The replacement update mechanism will be a script installed on your
system. The advantage of downloading the update mechanism before
running it is that it allows you to upgrade the upgrade mechanism.
Naturally the disadvantage is that you have to download it. Debian
systems have a mechanism for this; we'll use it.
It's understandable why you might want to pull this off a server in case
how you have to upgrade things changes for some reason, but we're moving
toward following Debian's lead on these things to the greatest extent
possible.
Okay Ivan, you can "I told you so" now. I didn't see any major gotchas
to changing the version and was SURE there'd be no reason to write the
convoluted comparison function until after everything was nicely redone
and restructured and whatnot. Fortunately I only need it in the main
script for now, and will hopefully very soon be able to just load it
from a common function file and use it where needed.
I still don't regret doing it, but all the work I had to do in order to
make sure I didn't screw it up (or rather that I fixed it after screwing
it up) are totally on me.
What's still missing from this is a version comparison mechanism. The
reason why it is missing is that we only use this in one place at the
moment, and if you have a version string that is not three digits, your
version is recent enough. This means we can save this for when there
are a common functions script to import and make the comparisons for us
without code duplication.
Ivan writes pretty dense scripts in some ways, but not others. Mostly
he likes to collapse statements to a single line and using && and || in
place of if constructs. Reduces file size and theoretically speeds
execution, but it makes community development tougher and the speed
gains are questionable.
I've begun removing multiple successive writes to a single file such as
those using tee as a means to write files as root. Clean up enough of
those and you will have a noticable performance impact, although again
there's no evidence there are enough of them here to see one.
Removed a few dead/commented code blocks and restructured a couple of
conditionals to make the no-action condition the else case.
Finally, bumped the version. This isn't all that'll go into 1.5.1 but
it's a start.
One of the reasons I held off on doing this before is that there are a
lot of complex one-line seds in here that I expect _will_ be broken by
this. More than a few of these will assume, depend on, require, and
break if specific hardcoded whitespace is not found. That's problematic
anyway--when whitespace isn't syntactic, you shouldn't do that. So it's
time to fix these anyway.
Found some checks that assumed all Debian was wheezy, and also a bunch
of use of cut assuming that there will never be a Debian version higher
than 9.0. Let's just futureproof that code right now. This closes#56
and uses the method described therein anywhere -c 1 is used now. For
the checks against -c 1-2, we still use -d . -f 1 as described in the
issue, but modify the following conditionals to test for just the
numeric, without the decimal.
