appserver.io is a multithreaded application server for PHP, written in PHP. Yes, pure PHP! If you know anything about PHP, you're probably thinking we might be crazy. Well, we aren't. We are dead serious (but we most certainly still love having fun!). appserver.io overcomes some of the biggest overhead issues most PHP (CGI) programs have in common, through a blazingly fast and rock solid infrastructure and with concepts new to PHP. At the same time, appserver.io offers PHP developers the fundamental core features found in most popular frameworks today, yet not intending to be a framework at all. It is a suprizingly fun infrastructure for PHP development, allowing you to build powerful applications without needing the bulk of a PHP framework. appserver.io includes great features like... appserver.io also supports Aspect Oriented Programming (AOP), which is a programming paradigm also found in the most popular frameworks today, like Laravel. AOP allows the separation of cross-cutting concerns within a program, allowing developers to create even more modular systems. With appserver.io, it is our goal to establish a solution as the next standard for enterprise applications written in PHP. With your help, we can reach this goal.

            Search requests timing out with concurrent transactions in MarkLogic
            Asked 2022-Apr-11 at 11:46

            Apologies here in advance for this non-simplified use case.

            During one of my data load processes, concurrent request transactions are used to fill MarkLogic.

            Each concurrent thread does the following operations at a high level:

            ...

            ANSWER

            Answered 2022-Apr-07 at 20:54

            When debugging, we do see concurrently when this transaction is being run, documents returned in the cts:search are locked for updates in other transactions. We are well aware of this possibility and are okay with it.

            You may think that you are okay with it, but you are running into performance issues that are likely due to it, and are looking to avoid timeouts - so you probably aren't okay with it.

            When you perform a search in an update transaction, all of the fragments will get a read-lock. You can have multiple transactions all obtain read locks on the same URI without a problem. However, if one of those transactions then decides it wants to update one of those documents, it needs to promote it's shared read-lock to an exclusive write-lock. When that happens, all of those other transactions that had a read-lock on that URI will get restarted. If they need access to that URI that has an exclusive write-lock then they will have to wait until the transaction that has the write-lock completes and lets go.

            So, if you have a lot of competing transactions all performing searches with the same criteria and trying to snag the first item (or first set of items) from the search results, they can cause each other to keep restarting and/or waiting, which takes time. Adding more threads in an attempt to do more makes it even worse.

            There are several strategies that you can use to avoid this lock contention.

            Instead of cts:search() to search and retrieve the documents, you could use cts:uris(), and then before reading the doc with fn:doc() (which would first obtain a read-lock) before attempting to UPSERT (which would promote the read-lock to a write-lock), you could use xdmp:lock-for-update() on the URI to obtain an exclusive write-lock and then read the doc with fn:doc().

            If you are trying to perform some sort of batch processing, using a tool such as CoRB to first query for the set of URIs to process (lock-free) in a read-only transaction, and then fire off lots of worker transactions to process each URI separately where it reads/locks the doc without any contention.

            You could also separate the search and update work, using xdmp:invoke-function() or xdmp:spawn-function() so that the search is executed lock-free and the update work is isolated.

            Some resources that describe locks and performance issues caused by lock contention:

            Cannot get webpack --watch or dev server to work using Lando to run a local Drupal environment
            Asked 2022-Apr-02 at 15:49

            I've scoured the internet and have bits and pieces but nothing is coming together for me. I have a local Drupal environment running with Lando. I've successfully installed and configured webpack. Everything is working except when I try to watch or hot reload.

            When I run lando npm run build-dev (that currently uses webpack --watch I can see my changes compiled successfully into the correct folder. However, when I refresh my Drupal site, I do not see that changes. The only time I see my updated JS changes are when I run lando drush cr to clear cache. Same things are happening when I try to configure the webpack-dev-server. I can get everything to watch for changes and compile correctly but I cannot get my browser to reload my files, they stay cached. I'm at a loss.

            I've tried configuring a proxy in my .lando.yml , and have tried different things with the config options for devServer. I'm just not getting a concise answer, and I just don't have the knowledge to understand exactly what is happening. I believe it has to do with Docker containers not being exposed to webpack (??) but I don't understand how to configure this properly.

            These are the scripts I have set up in my package.json , build outputs my production ready files into i_screamz/js/dist, build-dev starts a watch and compiles non-minified versions to i_screamz/js/dist-dev - start I have in here from trying to get the devServer to work. I'd like to get webpack-dev-server running as I'd love to have reloading working.

            I've updated my code files above to reflect reflect a final working setup with webpack. The main answer was a setting in /web/sites/default/settings.local.php

            **Disable CSS & JS aggregation. **

            $config['system.performance']['css']['preprocess'] = FALSE; $config['system.performance']['js']['preprocess'] = FALSE;

            I found a working setup from saschaeggi and just tinkered around until I found this setting. So thank you! I also found more about what this means here. This issue took me way longer than I want to admit and it was so simple. I don't know why the 'Disabling Caching css/js aggregation' page never came up when I was furiously googling a caching issue. Hopefully this answer helps anyone else in this very edge case predicament.

            I have webpack setup within my theme root folder with my Drupal theme files. I run everything with Lando, including NPM. I found a nifty trick to switch the dist-dev and dist libraries for development / production builds from thinkshout.

            I should note my setup does not include hot-reloading but I can at least compile my files and refresh immediately and see my changes. The issue I was having before is that I would have to stop my watches to drush cr and that workflow was ridiculous. I've never gotten hot reloading to work with with either BrowserSync or Webpack Dev Server and I might try to again but I need to move on with my life at this point.

            I've also note included sass yet, so these files paths will change to include compilation and output for both .scss and .js files but this is the basic bare min setup working.

            You are running the project via Java 1.8 and add the --add-opens option to the runner. However Java 1.8 does not support it.

            So, the first option is to use Java 11 to run the project, as Java 11 can recognize this VM option.

            Another solution is to find a place where --add-opens is added and remove it. Check Run configuration in IntelliJ IDEA (VM options field) and Maven/Gradle configuration files for argLine (Maven) and jvmArgs (Gradle)

We are looking to have this resolved with 22.0.0.2 which is scheduled to be available tomorrow if we don't run into any additional snags and the io.openliberty publishing goes well.

            When an Oauth provider is used to delegate authentication, then does the appserver return any token to the caller?
            Asked 2022-Feb-05 at 19:35

            In Oauth and Openidconnect, the appserver endpoint invocation starts the Oauth flow and the app server gets the token from the auth server and is able to pass the token to resource server to access resources (delegation) on behalf of the resource owner.

            The token exchange happens between the app server and resource server, and the token never arrives at the end users browser.

            I'm working on a web api (aka app server) that will be consumed by a mobile app. There is no other server involved. Presently the login endpoint returns a signed JWT token to the user if correct credentials are supplied (validate against the db). User places this token in the header of the subsequent request.

            Assuming I don't want to have a user db and validate logins, and instead delegate the auth check to another service like azure b2c or firebase (that use the Oauth), then I assume the flow is like given below:

            1. Api registered the firebase/azure b2c (let's call this the provier) clientid, secret.
            2. User invokes login endpoint of my api
            3. The api invokes the provider's Oauth flow.
            4. User gets popup to authenticate with the provider.
            5. Eventually the provider will send the token (containing the claim like username) to the api (aka app server)

            Does the user get back any token? Otherwise, when the user makes subsequent endpoint calls, then how is the endpoint able to identify who is this user and whether he is already authenticated?

            Although it is okay to send back the access token to the user , but from the security best practise 's point of view , it is better not to do it which I quote the reasons as follow from this:

            Because of the issues outlined above, the best security recommendation for an SPA is to avoid keeping tokens in the browser at all. This can be achieved with the help of a lightweight back-end component, often described as a Backend-For-Frontend.

            The backend component can then be configured as a confidential OAuth client and used to keep tokens away from the browser. It can either be stateful and keep tokens in custom storage, or stateless and store the tokens in encrypted HTTP-only, same-site cookies. Whichever variant is chosen, the backend component creates a session for the SPA, using HTTP-only, secure, same-site cookies, thus enabling a high level of security. Such cookies cannot be read by scripts and are limited to the domain of the SPA. When combined with strict Content Security Policy headers, such architecture can provide a robust protection against stealing tokens

            Also from here ,they suggest for mobile app 's OAuth2 best practise , it should perform the OAuth flow inside a system browser component.

            (1) Yes. The app server will store the token for each user.

            (2) It uses cookie to maintain the user session. The idea is that after confirming the user is authenticated (i.e get the access token) successfully , the app server will generate an unique session ID for this user and associate this session Id to the user 's access token. This session ID will then be sent back to the user 's browser as a cookie such that when the user 's browser sends subsequent requests to the app server , the app server can get back this session ID from the cookie and use it to get back his access token.
