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.
Closing and re-opening that very same log file shouldn't reset the
counter, otherwise some log files may exceed the max limit per file as
their offset indicator is reset each time they are re-opened.
On incoming connection timeout we log the remote endpoint which isn't
available if it was already disconnected - an exception is thrown. Get it
as long as we're still connected not to lose it, nor to get an exception.
While analyzing a possible memory leak, we encountered several coroutine
exception messages, which unfortunately do not provide any information
about what exactly went wrong, as exception diagnostics were previously
only logged at the notice level.
Although there is locking involved here, it shoudln't take too long for
the thread to actually acquire it, since there aren't that many threads
dealing with endpoint clients concurrently. It's just wasting pointless
time trying to obtain a CPU slot.
