We'd heard from a few people that Perfect isn't as "Swifty" as it should be. We'd love to hear what this means to you, and where you think we could improve Perfect to be more so. What is "Swifty" to you that Perfect isn't?

The last commit was 3 months ago and I haven't seen much recent activity. ~~I am unable to join the Slack channel~~. So is this project basically dead?

EDIT: I've got to join Slack now after some failed attempts (was getting HTTP 502-504)

I am looking to decide what to use for a backend and thought of server-side Swift (instead of going with some NodeJS thing) and found this but I am quite skeptical.

Hello Perfect team, I tried following the README Quick Start instructions.

After I enter the following in Terminal: git clone https://github.com/PerfectlySoft/PerfectTemplate.git cd PerfectTemplate swift build

I get: /Users/matthewtso/git/PerfectTemplate/Packages/PerfectThread-0.10.0/Sources/ThreadQueue.swift:210:97: error: cannot convert value of type 'UnsafeMutablePointer<Void>' (aka 'UnsafeMutablePointer<()>') to expected argument type 'UnsafeMutablePointer<_>'

/Users/matthewtso/git/PerfectTemplate/Packages/PerfectThread-0.10.0/Sources/ThreadQueue.swift:233:37: error: value of type 'Unmanaged<IsThisRequired>' has no member 'toOpaque'

error: exit(1): /Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swift-build-tool -f /Users/matthewtso/git/PerfectTemplate/.build/debug.yaml

Checking my Swift version returns the following: Apple Swift version 3.0 (swiftlang-800.0.30 clang-800.0.24) Target: x86_64-apple-macosx10.9

I'm pretty new and not sure how to diagnose this, is there something I can try to fix this? Thanks!

Hi Everyone!

I have been hard at work learning Perfect and making tutorial videos in my spare time. This is by far not finished yet, but since the introduction section is done, I figured it was time to share it with the community.

So beginning today I have four videos for you:

1. How to setup an Xcode Workspace (HelloPerfect Part 1): https://www.youtube.com/watch?v=LNU6L2pnq0k
2. How to host your first Web Application with a custom route (Hello Perfect Part 2): https://www.youtube.com/watch?v=rYV9M64pPv8
3. How to host web content (a website) with Perfect: https://www.youtube.com/watch?v=J441eJ40PH4
4. How to host dynamic content using Mustache Templates and Handlers: https://www.youtube.com/watch?v=SX9aX2aYzpw

Update: May 5th:

Video 5 is live!

1. How to encode JSON: https://youtu.be/EwoXL_ZnA3s

I have also combined them into one easy playlist here: https://www.youtube.com/playlist?list=PLE2M81Pddau3LrJRGPbc6UXMy3VQuA2lL

Update: May 6th:

Video 6 is live!

1. Start working with POST requests: https://youtu.be/IwkbRxDZaBA

More to Come

Again, this is only the beginning for me as I prepare an entire online course in everything Perfect has to offer. Things I have planned:

• How to hookup a database and work with the database connectors
• How to use Perfect's built-in JSON
• How to create a Private API & an iOS app that uses that API
• How to create a public API
• How to work with Perfect's built-in curl library
• How to tie all of it together in one application (an API, web app, mobile app, database, custom routes, and mustache as one project)

If you like my tutorials, please give hit the like button in the upper right corner (looks like +😀) and select the "thumbs up" to vote for me in the competition, and thank you for watching!

Edit: Made Voting Instructions More Clear Edit 2: Added Video 5: Encoding JSON Edit 3: Added Video 6: Working with POST

I see this great project is under the Gnu Affero License, which basically implies that any software built using this server will need to be under the same license (see https://www.gnu.org/licenses/gpl-faq.html#LinkingOverControlledInterface).

Swift.org has been released under the Apache License. Any chance this project would consider doing the same ?

I'm attempting to build hash a1a9fe27c9a5fef4434c50ede050dea206807423 and this is what I get on Ubuntu 14.04 when making PerfectLib:

Hello,

I built the latest version of PerfectLib with the correct Swift snapshot. However, when I import the .xcodeproj or a compiled version of the framework into Xcode whenever I try to compile my program the compiler says "Missing required module 'OpenSSL'." Also, I ran 'brew link openssl --force' to force symlink the openssl libs to /usr/local/include/openssl.

Thanks!

I use make to compile PerfectLib (sudo make) ,but show this error: swift -frontend -c ICU.swift NetNamedPipe.swift File.swift Threading.swift LibEvent.swift Bytes.swift FastCGI.swift LogManager.swift NetTCPSSL.swift PerfectServer.swift WebConnection.swift Closeable.swift FastCGIServer.swift Net.swift Utilities.swift MimeReader.swift NetTCP.swift SessionManager.swift WebRequest.swift HTTPServer.swift MimeType.swift PageHandler.swift SQLite.swift WebResponse.swift Dir.swift Mustache.swift PerfectError.swift SysProcess.swift DynamicLoader.swift JSON.swift Utilities-Server.swift Routing.swift StaticFileHandler.swift WebSocketHandler.swift JSONConvertible.swift -primary-file cURL.swift

I'm assuming this can't be deployed to a real production server yet, since it can't run on linux. Is that something that is only reconcilable after Apple open sources the language?

Nevertheless, not being able to scale the servers made is definitely an issue.

• Building Perfect via SPM
• Debian 8.5 (jessie)
• Beaglebone Black (armv7 / 32bit )

In addition to build errors reported on the Ubuntu (#187), there are two additional ones that pop up on the Beaglebone Black, a 32bit device.

Hello,

I have a problem when i launch the perfectserverhttp from Ubuntu 15-10.

The server launches properly, but then i can't manage to work with it. The message "The file "/" was not found" is displaying on the navigator.

Could it be because i use a virtual machine? Or did i do something wrong with the installation? I followed step by step the instructions written in the Readme files.

Thanks in advance!

Hi, we recently moved from precompiled Perfect to one resolved via SPM.

We stumbled upon the crash explained in:

https://github.com/PerfectlySoft/Perfect/issues/296

only when running in Release configuration. On the very first request, app crashes in

return UnsafePointer(bytesArray).withMemoryRebound(to: Int8.self, capacity: bytesArray.count) { return String(validatingUTF8: $0) }

Now this seems to be fixed in PerfectLib from version 4.0 onwards by following commit:

https://github.com/PerfectlySoft/Perfect/commit/135fb33471f1dd316eb323f8a94d701bde2efa85#diff-69391fd63fbd9d34d8f320a64858e895ea4ab70dc9e87fafe0cfe701de2db5b0L250

The problem is that no publicly available version of HTTP and HTTP-Server depends on PerfectLib 4.0, which essentially is letting me with no access to the fix for this crash.

Long story short, is there an intent from your side to publish HTTP/HTTP-Server version 4.0 that depends on PerfectLib 4.0?

Thanks in advance. Uros

PerfectLib doesn't compile on M1 macs. I get an error in Log.swift on line 73. Has anyone been able to get this to work?

Cannot convert value of type 'CVaListPointer' to expected argument type '__darwin_va_list?' (aka 'Optional<UnsafeMutablePointer<Int8>>')

Platform: Linux(not happen on Mac) What happen: the server shutdown How to happen: remove permeter escapeVS, request body is '👨‍👩‍👧‍👦' Strange: set parameter escapeVS or request not contains '👨‍👩‍👧‍👦', this wouldn't happen. My question: Is the postParams wrong when the request body contains some speical emoji?

this is my request:

curl --location --request POST 'http://localhost:8181/emoji/parse?a=b' \
--header 'Content-Type: text/plain' \
--data-raw '👨‍👩‍👧‍👦'

this is my code:

func emojiParse(request: HTTPRequest, response: HTTPResponse) {
    do {
        let escapeVS = request.param(name: "escapeVS", defaultValue: "false")?.elementsEqual("true") ?? false
        if let raw = request.postBodyString {
            response.setHeader(.contentType, value: MimeType.forExtension("json"))
            let result = raw.translateUEmojiCode(escapeVS)
            try response.setBody(json: result)
        }
    } catch {
        response.status = .internalServerError
        response.setBody(string: "Error handling request: \(error)")
    }
    response.completed()
}

this is my debug on Mac:

this is the error log:

--------UPDATE----------

this request also trigger the bug.

curl --location --request POST 'localhost:8181/emoji/parse?escapeVS=false&👨‍👩‍👧‍👦=b' \

--------UPDATE----------

Looks like a swift unicode bug on Linux?

I've built a listener server with Perfect HTTP, listening on certain routes for Webhooks called by GitLab on certain repository actions. The project is a work in progress and primarily for my own use, though it is public on https://gitlab.com/apricum/gitlab-listener.

I'm starting the server through systemd via systemctl start and the likes. I've found it crashes after a seemingly random amount of time, sometimes a few hours, other times not even ten minutes. Reading the log with sudo journalctl -u gitlab-listener (where gitlab-listener is the name of the systemd service file), as follows:

Hello everyone, I'm glad to learn how to use Perfect, but I encountered some problems. When I used Perfect Assistant to create an Empty Executable Project, I found that HTTPServer could not be dragged, and I was prompted "The Package.swift file could not be parsed", Is there a problem with my settings?
