p-timeout | Timeout a promise after a specified amount of time | Reactive Programming library

That is due to Raspbian using NetworkManager prior to version 1.18, which is when the functionality routing-rules was released. It wouldn't otherwise be a problem, however, Ansible nmcli module expects that this parameter is there when it attempts to create the interface, but then nmcli fails with this weird message.

There's already an open issue for that: https://github.com/ansible-collections/community.general/issues/3948

The advice the warning message is giving refers to the package.json of your code as opposed to the package.json for the fetch library. If you don't already have a package.json at the root of your project (that is ./package.json instead of ./node_modules/node-fetch/package.json) you will need to create one. If you already have a ./package.json file or once you have created one you just need to add the line:

The closest possible solution I found was from AWS Sagemaker example

Effectively solution uses nginx as rate limiter and gunicorn as load balancer. On my locust tests to avoid queue overflow, I had to add limit_req_zone with static key.

System throughput increased three order of magnitude, flask on its own is the paragon of unscalability.

Based on the source code here http-auto-gzip is only available when uWSGI is compiled with the UWSGI_ZLIB flag.

You will need to have the zlib1g-dev Ubuntu package installed when you install (compile) uWSGI for that to happen.

You're using the unsupported parameter EVENTSTORE_EXT_HTTP_PORT. See more in the line from logs:

The exception you get SplitBrainMergeValidationOp means that the Hazelcast cluster might have been started in the split-brain and later tries to merge into one cluster. Could you check if you follow all the Hazelcast Kubernetes recommendations?

Especially, check if you use StatefulSet (not Deployment). In the case of DNS Lookup discovery, using Deployment may cause Hazelcast to start in the split-brain mode.

Are you still having this error? I managed to fix this by downgrading windows kube-proxy to at least 1.20.0. There must be some missing config or bug for 1.21.0.

There are a quite a few points here. First, I'd say that playing with memory models might not be the first thing to try when confronted with a verification issue (especially, since you're not using floating point arithmetic, the +real component is completely useless). I'd thus propose to remove -wp-model from the equation altogether, the default choice is usually good enough. On the other hand, adding -wp-rte to also check for potential runtime errors might be interesting.

When you specify \valid_read(s1), you're saying that you can access s1[0], but nothing else. If you want to speak about the validity of several memory cells, you can use \valid_read(s1 + (0 .. n)), or, in the case of null-terminated C strings, \valid_string(s1).

Your assumes clauses in both behaviors of stringCompare are incorrect: we're only searching for a difference until strlen(s1) (included), not until n (which by the way is pretty useless and could probably be removed: you want to specify that strlen(s{1,2}) are bounded, but SIZE_MAX in stdint.h should do the trick). Moreover, the reverse of \forall i, P(i) ==> Q(i) is \exists i, P(i) && !Q(i) (i.e. do not use ==> after \exists).

It would be better to use size_t for C variables that are meant to be used as offsets. Otherwise weird things might happen for very large strings.

You lack some invariants. Basically, in stringCompare, you must capture the fact that:

• i stays between 0 and strlen(s1) (resp. strlen(s2))
• the current value of s1 is in fact \at(s1,Pre)+i (ditto for s2)
• so far, all elements of s1 and s2 are equal...
• ...and non-null

Since the default architecture targeted by Frama-C uses char as signed, the conversion to unsigned char in the return statement will confuse WP. This is admittedly a weakness of WP itself.

For stringLength, it is also necessary to require something like valid_string(str). However, this time you must constrain strlen(str) to be strictly less than SIZE_MAX (assuming you change your return type and the declaration of result to be size_t), since result must go up to strlen(str)+1 without overflowing.

Again, the loop invariants must be strengthened: result is bounded by strlen(str), and we must indicate that so far all characters are non-0.

Finally, in your main function, another weakness of WP prevents to check that the pre-conditions of stringCompare are fulfilled. If hello and helli are defined explicitely as char arrays, then everything will be fine.

tl;dr: the code below can be entirely proved with frama-c -wp -wp-rte file.c (Frama-C 22.0 Titanium and Alt-Ergo 2.2.0)
