varstord-guard has following configuration in the service file

After=message-switch.service syslog.target

This means varstored-guard needs to be stopped before
message-switch, otherwise, it will hung and finally be killed by
systemd during xe-toolstack-restart

Move message-switch to the begining of the list to shutdown last
as all other daemons depend on it

Note: the list order is reversed by `for svc in $SERVICES`

We need to explicitly install python2, since it is no longer the default.

Eventually we may want to drop this completely, but we're not there yet.

We do not publish or use the opam packages from this repo,
and therefore pinning is unnecessary.
'opam install --deps-only --with-test .' works without pinning on the version of 'opam' we have here.

Pinning ~71 packages is very slow since it makes a full copy of the source+.git folder every time.
Skip pinning, this also saves a few gigabytes of disk space.

This also makes the cleanup-xapi-environment action a no-op, so remove it.
(in fact it'd fail because the output of opam list with master pins is empty).

For testing the correctness of opam packages:
* we still have the xs-opam CI
* we can introduce opam-dune-lint that statically checks opam and dune for missing dependencies (needs new release first)

This reduces CI times:
* Run OCaml tests: from 15m24s to 10m16s
  * Setup XenAPI environment: from 7m1s to 5m55s

Setting DUNE_CACHE_STORAGE_MODE=copy is needed during 'opam install',
otherwise dune builds inside opam packages won't be cached.
The sandbox used by opam is another partition/device and hardlinking fails with EXDEV.

Now that we no longer pin the local opam packages we have
a few more GiB of disk space, and we don't need to rm pre-existing files.
This speeds up this step a little.

The dune cache inside 'setup-ocaml' is trimmed to 5GB/jobcount,
which is currently about 10.
But not all jobs here use the dune cache, so separate the workflows.
(Also the dune cache will get compressed afterwards).

The SDK build does use the dune cache, but eventually it might become smaller,
e.g. if we change it to install just the dependencies needed for SDK gen,
and not everything. It does have a lot of unrelated jobs though.

The workflows need a unique name, otherwise they cancel each-other.

The dune cache is ~1.4GB now compressed, which should speed up
the setup-ocaml step on next run as more dependencies will be cached.

Setup XenAPI environment now only takes 2m51s instead of 5m55s.

- Removes large package listing from build instructions.
- Adds explanation about tags when working from a clone of a fork of the repo.
- Includes miscellaneous changes to wording.

We should eventually separate the opam dependency install into its own job
that uploads an artifact/cache that other jobs can reuse (and that should have a bigger dune cache),
however for now just trim the size of the cache.

The default is 5GiB, which results in ~1.4GiB compressed, which would hit the 10GiB cache size limit in GitHub way too often.
We may need to tweak this value in the future.

Exposed system_list_methods in C# SDK. Correction to github workflow.
xapi-tracing-export is a new library separated from xapi-tracing. This
library is needed by xapi-clusterd (and probably other components that
require tracing as well). So install it as a library in the Makefile.

…/CP-48195-instrument-forkexecd-client

CP-48195: Instrument client side of `forkexecd`
- Use `Types.checkError` instead of throwing a generic `XenAPIException`. This ensures the `Types.XYZ` family of exceptions are being used
- Use `@JsonValue` to ensure base class objects are deserialised as a simple opaque_ref string, as opposed to a mapping of each field. This ensures the API's behaviour is unchanged.
- Parse the results of `task.getResult` calls. The jsonrpc method returns value payloads of the form `"value" : "<value>OpaqueRef:XYZ</value>"` so we need to strip the surrounding XML

The query on HTTP endpoint /updates will return the available updates in
JSON format. Prior to the changes in this commit, if a query arrives
when another query is being handled, a "GET_UPDATES_IN_PROGRESS" error
will be returned immediately. This behaviour is not friendly to GUI
client XenCenter.

In this commit, the behaviour is changed to wait and retry in handling
the query in xapi since the "*_IN_PROGGRESS" error is a transient
failure. Tolerating it in xapi (server) side avoids error handling in
client side.

With the change, the "GET_UPDATES_IN_PROGRESS" will not be an error
exposed to users any more. Therefore it is removed.

CA-389319: Wait and retry for GET_UPDATES_IN_PROGRESS
As part of a start, resources are allocated for a VM in "scheduled_to.."
fields. These need to be cleared if the start fails. It turned out that
this was incomplete for PCI slots and those were leaking. This patch
tries to be more systematical about it.

This is mostly copied from the jekyll version at xapi-project.github.io and
amended for Hugo. The main difference is that all XenAPI pages have now been
integrated with the main menu in the left side bar, including the menu of the
XenAPI classes.

Some automation is left to do in order to take the `doc/data` files from a
build of `ocaml/idl` and update the class pages using the script
`doc/make-class-pages.py`. Also the overview of xapi releases is still missing,
as well as some of the API guides.

Finally, there is some overlap with markdown files in `ocaml/doc`, which needs
to be sorted out.

Looks like we'll need to add the new xapi-fdcaps.opam to xs-opam, or the CI fails (the downside of not pinning every package anymore, opam doesn't get to know about new local packages).
Tried pinning just the new packages, but that also hides the other packages from opam-depext, resulting in a lot of missing system dependencies, and currently in the ci you can't control the 2 lists separately.

Move xapi-fdcaps to be a subpackage: xapi-stdext-unix.fdcaps.
Change xapi-fd-test to be an internal-only package, and run its tests as part of xapi-stdext-unix.

This avoids having to update xs-opam to define a new opam package.
