The installation documentation currently implies that all commands are
being prompted by the root user or an user with root-like privileges.
This is now explicitly stated and, additionally, another if-guard was
added to not include the "Add Icinga Package Repository" section for
Windows, as it does not fit there.
Closes#9959.
to stick to CMake pre-v3.29 behavior. CMake v3.29 introduces CPACK_WIX_INSTALL_SCOPE. Its default conflicts with the ALLUSERS property in our icinga-installer/icinga2.wixpatch.cmake.
Before ae693cb7e1df1b885142854cf8a0f8a7600a3fb7 (#9577) we've repeatedly looped over all items in parallel like this:
while not types.done:
for t in types:
if not t.done and t.dependencies.done:
with parallel(all_items, CONCURRENCY) as some_items:
for i in some_items:
if i.type is t:
i.commit()
I.e. all items got distributed over CONCURRENCY threads, but not always equally. E.g. it was the hosts' turn, but only two threads got hosts and did all the work. The others didn't do actual work (due to the lack of hosts in their queue) which reduced the performance. c721c302cd9c96bee25a20b3862dad347345648a (#6581) fixed it by shuffling all_items first. ae693cb7e1df1b885142854cf8a0f8a7600a3fb7 (#9577) made the latter unnecessary by replacing the above algorithm with this:
while not types.done:
for t in types:
if not t.done and t.dependencies.done:
with parallel(all_items[t], CONCURRENCY) as some_items:
for i in some_items:
if i.type is t:
i.commit()
I.e. parallel() gets only items of type t, so all threads get e.g. hosts.
When a HTTP connection dies prematurely while the response is sent,
`http::async_write()` sets the error code to something like broken pipe for
example. When calling `async_flush()` afterwards, it sometimes happens that
this never returns. This results in a resource leak as the coroutine isn't
cleaned up. This commit makes the individual functions throw exceptions instead
of silently ignoring the errors, resulting in the function terminating early
and also resulting in an error being logged as well.
Given that the internal `config::Update` cluster events are using this
as well to create received runtime objects, we don't want to persist
first the conf file and the load and validate it with `CompileFile`.
Otherwise, we are forced to remove the newly created file whenever we
can't validate, commit or activate it. This also would also have the
downside that two cluster events for the same object arriving at the
same moment from two different endpoints would result in two different
threads simultaneously creating and loading the same config file -
whereby only one of the surpasses the validation, while the other is
facing an object `re-definition` error and tries to remove that config
file it mistakenly thinks it has created. As a consequence, an object
successfully created by the former is implicitly deleted by the latter
thread, causing the objects to mysteriously disappear.
