Daniel Barlow 6db982f25f preinit: pause before exiting 
as explained in the comment, this is to give us a
chance to see error messages before the kernel panics

Daniel Barlow 61dc5beca8 preinit: parse rootfstype from kernel command line 2023-10-19 18:56:09 +01:00
Daniel Barlow 8798ee9830 partial fix for timeout handling 
1) "Unknown transfer id" message was because the local variable "tid"
is not a transfer id, it is a sequence number  - so the check was
actually comparing expected vs actual acknowledged sequence number,
not TID.  It's still a problem if we get the wrong one, but it
indicates a lost packet (so we should resend) not a packet that was
sent from somewhere else.

2) if the ACK packet has not been received, our retry should involve
_resending_ it, not just trying to wait for it again.

3) I have removed the timeout condition for terminating the resend
loop, because in practice (assuming both ends have the same timeout
setting) all it did was ensure that the loop only ran once. The
timeout is supposed to regulate how long we wait for before retrying
(it doesn't do this, we wait indefinitely), not how long we wait for
before giving up.

Daniel Barlow c18f07f02f aarch64: make tftpboot work 
- patch dtb to add reserved-memory stanza for the phram device to use
  (aarch64 does not accept memmap= command line option)

- patch phram driver to use memremap() instead of ioremap() as
  ioremap can't be used for system ram on arm devices
 2023-10-09 19:47:57 +01:00

Daniel Barlow be22fbbb0a bootable aarch64 liminux with qemu 
I may have broken the run-liminix-vm command a bit for MIPS due to
necessary changes in how we pass the command line.  If CI isn't green
for this commit and youre trying the worked examples, I suggest
reverting to the commit before this one.

Daniel Barlow 8f97c5bf3c anoia service :events method behaves as iterator 2023-09-12 20:46:52 +01:00
Daniel Barlow 7904c6bfe9 anoia users now need lfs 
... and we need to figure out how to do transitive
dependencies, because this is not a great experience
 2023-09-12 18:46:04 +01:00
Daniel Barlow 343d3b6508 writeFennel is writeFennelScript with knobs on 
The second parameter is now an options attrset, wherein we will pile
all kinds of cool stuff.

Right now the only cool bit is `mainFunction`, which allows you to
compile a fennel module into a lua script and name the function that
should be executed when the script runs. This makes it easier to
write testable Fennel code, because the test script can require the
module and call stuff in it.

Daniel Barlow 870da62a1e anoia.svc outputs may be directories (read as table) 2023-09-09 00:30:02 +01:00
Daniel Barlow 0312f7a999 fennelrepl look for .fnl before .lua 
this means fennelrepl in nix-shell will prefer local
source files to generated lua files, making it easier
to change library code without restarting the shell
 2023-09-09 00:11:35 +01:00
Daniel Barlow 9dd3cf23b4 anoia.fs.mktree replaces mkdir 
This uses lfs to make the tree in-process instead of
shelling out to the mkdir command
 2023-09-08 21:17:42 +01:00

 2023-09-08 21:02:26 +01:00
Daniel Barlow 12e25722fa odhcp-script: delete stale dirs from previous runs 
This requires adding LFS as a dependency because native Lua has
no way to iterate a directory, but it seems to be Not Huge and
hopefully we'll have other uses for it

Daniel Barlow fbb2c04132 move module-based-service parameter types into service 
This is in preparation for writing something that extracts them
into documentation.

user configurations now call config.system.service.foo.build { ...params }
instead of config.system.service.foo

the parameter type definitions themselves now move into the
config stanza of the module referencing the service

new helper function  liminix.callService

The only service moved so far is dnsmasq
 2023-08-04 20:39:29 +01:00

Daniel Barlow 682183a88d move typeChecked into pkgs.liminix.lib 2023-07-14 20:22:29 +01:00
Daniel Barlow 69e6eb5a89 accept attr args to pppoe service, and typecheck them 
We use (abuse, arguably) the nixos module system for typechecking.  Un
the plus side, it gives us documentation of the options and their
expected types. On the downside, the error message doesn't tell us
the file in which the error was encountered.

(This is subject to change, if I can find a better way)

Daniel Barlow c3bb33c9ce add fennelrepl package 
Runs fennel using a Lua compiled with the same options as the
host system, and with packages set up so it can find all the local
Lua packages

To shorten the dev feedback loop further, allows FENNEL_PATH to be set
on the command line so you can point directly it at the Fennel sources
for some library you're working against instead of having to run
nix-build and compile them to Lua
 2023-07-04 22:58:51 +01:00

Daniel Barlow 3900683413 simplify protocol for watchers of service output directories 
Previously: the service wrote a timestamp and the receiver
read and parsed it to see if there was new data

Now: the service writes and removes a .lock file to prevent
the receiver reading partial data. The receiver is responsible
for remembering the *previous* state and only updating if it's changed
