Check ispecs against ipolicy on instance modify

When modifying an instance, so far the specs were not checked against
the ipolicy. This patch fixes this issue.

Note that for backend parameters which have a minimum and a maximum
value (currently only memory), it checks both limits against the
ipolicy. Because locking of the instance's node group was necessary, a
TODO of commit b8925b86 was fixed as well.

11 years agorapi: Add new user option for querying
Michael Hanselmann [Thu, 8 Nov 2012 18:31:14 +0000 (19:31 +0100)]
rapi: Add new user option for querying

This was requested in issue 301. Before this patch, requests to
“/2/query/*” and “/2/instances/*/console” would require authentication
with a user with write access. Since that is not strictly necessary, a
new user option named “read” is added.

Console information can also be retrieved as a normal query, therefore
the change applies there too.

This was the first user option to be added after “write”, therefore
quite a few changes were necessary. Documentation, including NEWS, is
updated as well.

11 years agoCleanup THH function use from built module namespace
Iustin Pop [Tue, 13 Nov 2012 16:27:23 +0000 (17:27 +0100)]
Cleanup THH function use from built module namespace

Currently, THH.hs "injects" into the built code names of library
functions like Text.JSON.makeObj, Ganeti.JSON.fromObj, etc. built
directly from strings, via (e.g.)

  varE (mkName "makeObj")

This means that the "makeObj" name must exist in the target module,
i.o.w. must be imported there. This leads to the strange case of
having to have imports that do not appear at all in the used
(template) code, but are needed to satisfy this "hidden" dependency;
look at Ganeti/Jobs.hs before this patch, for example.

This is also not very obvious, because we usually import Text.JSON
anyway; I only stumbled upon it while doing some cleanup work.

So to clean this up, the current patch changes the THH.hs to use not
string-derived, but identifier-derived names («'identifier» versus
«mkName "identifier"»); this is better, as the names must be
resolvable when compiling THH itself (once), and not when compiling
the multiple derived modules. As you can see, this allows removal of
extraneous imports from various modules.

Background information: an `mkName "foo"` results in a name of flavour
NameS (“An unqualified name; dynamically bound”) or alternatively to a
qualified name, but still dynamically bound. Whereas what we want is a
statically bound name: `'foo` results in a NameG flavour, “Global name
bound outside of the TH AST: An original name”.

One more explanation: the change is similar to going from 'x = eval
"map"' to 'x = map'; the name is no longer dynamically evaluated, but
statically when the module is compiled. In our case, previously names
were bound at target module compile time, now they are bound at THH.hs
compile time.
