            Adding Parameter to URL to Iterate in Python
            Asked 2021-Jun-15 at 21:09

            I have a Python script that I'm working on where I would like to iterate through a list of ID values at the end of a URL.

            This is my script so far where I would like to replace the 555 portion of the url with a list of ID values such that the script would do a POST for each of them. How can I accomplish that?

            You can use a for loop, with the range function to create a list of ids:

            React App running in Heroku fails when retrieving large amounts of data
            Asked 2021-Jun-14 at 18:09

            I have a react application (Node back end) running on Heroku (free option) connecting to a MongoDB running on Atlas (also free option). When I connect the application from my local machine to the Atlas DB all is fine and data retrieved (all 108 K records) in about 10 seconds, smaller amounts (4-500 records) of data in much less time. The same request from the application running on Heroku to the Atlas DB fails. The application running on Heroku can retrieve a small number of records (1-10) from the same collection of (108 K records), in less than a second. As soon as I try to retrieve a couple of hundred records the system fails. Below are the logs. I included the section of the logs that show a successful retrieval of 1 record and then failing on the request for about 450 records.

            I have three questions:

            1. What is the cause of the issue?
            2. Is there a work around in the free option of Heroku?
            3. If there is no work around in the free option, what Heroku pay level will I need to get to and what steps will I need to take to get this working? I will probably upgrade in the future but want to prove all is working before going in that direction.

            You're running out of heap memory in your node server. It might be because there's some statement that uses a lot of memory. You can try to find that or you can try to increase node memory like this.

            Answered 2021-Jun-14 at 05:40

            Since 7.0.0 is a Release candidate version, you should mention -rc and version. it becomes npm i ngx-bootstrap@7.0.0-rc.1 you can see install command from here.

            it is ready to go out, but it isn't proven yet so it's not ready to be marked as a stable release quite yet. You can think of it as a mature beta release. for more details, you can visit wikipedia

            Why is my upload incomplete in a NodeJS express app
            Asked 2021-Jun-14 at 03:53

            I need to upload a v8 heap dump into an AWS S3 bucket after it's generated however the file that is uploaded is either 0KB or 256KB. The file on the server is over 70MB in size so it appears that the request isn't waiting until the heap dump isn't completely flushed to disk. I'm guessing the readable stream that is getting piped into fs.createWriteStream is happening in an async manner and the await with the call to the function isn't actually waiting. I'm using the v3 version of the AWS NodeJS SDK. What am I doing incorrectly?




            Answered 2021-Jun-14 at 03:53

            Your guess is correct. The createHeapSnapshot() returns a promise, but that promise has NO connection at all to when the stream is done. Therefore, when the caller uses await on that promise, the promise is resolved long before the stream is actually done. async functions have no magic in them to somehow know when a non-promisified asynchronous operation like .pipe() is done. So, your async function returns a promise that has no connection at all to the stream functions.

            Since streams don't have very much native support for promises, you can manually promisify the completion and errors of the streams:

            Heroku - JavaScript heap out of memory
            Asked 2021-Jun-12 at 09:13

            I was able to run my react app locally without issues, however when i deployed app to heroku I got OOM errors. It's not the first time I deploy the app, however this time I add OKTA authentication which apparently cause this issue. Any advise on how to resolve this issue will be appreciated.

            Update elements of nested list with map and fcase
            Asked 2021-Jun-10 at 20:20

            I would like to use purrr:map() and purrr:pluck() to apply data.table::fcase() rules to elements within a nested list and update the list by reference.

            I can accomplish a working output using dplyr::mutate() but this output is in an unnested format and does not update by reference like data.table's := does.

            What is the limit on the number of "fast", "inlinable" properties in v8 object?
            Asked 2021-Jun-10 at 19:48

            Question for v8 experts.

            As we know, if the "shape" of the object does not change, v8 stores the object properties in a special array, and access them by index, which results in very fast access. I may be wrong on the details.

            As described in this blog post from 2018, the size limit for this array is 1022.

            Is this information still correct? Perhaps there were some improvements on this recently?

            Thank you!



            Answered 2021-Jun-10 at 19:48

            While I don't know how that blog post arrived at that number, the current value of kMaxNumberOfDescriptors is 1020, and the maximum number of entries in a PropertiesArray is 1023. Not sure why there's a difference, also not sure it matters... In a quick test, it seems that 1020 is the effective maximum, but maybe I'm overlooking some way to make an object grow to 1022 properties without transitioning to dictionary mode.

            Meta-observation: object handling in a JS engine is waaaay more complicated than just having a single limit. See e.g. TooManyFastProperties() for some of the fun.

            if the "shape" of the object does not change, v8 stores the object properties in a special array

            This is an incorrect simplification. In particular, adding properties (which constitutes a shape change) does not usually trigger a transition to dictionary mode.
