CURL Conference 2019 in Prague


The CURL conference (or meet-up) in Prague was a great way to learn a bit more about CURL and how people use it. Especially I leant about the roadmap, HTTP/2, HTTP/3 or Quic and TLS news. The sessions give a great insight what's new in CURL since the last conference, how some internal works and how the project is organized.

The event is organized with great help of some local Czech people from Charles University, which also provided the room. Daniel Stenberg, the author of CURL was of course the star of the show. But there were other notable attendees from various bigger companies including Teamviewer, Akamai, Google, Red Hat, wolfssl, Apiary (part of Oracle) and a few startups where I forgot the names and a few self employed people. The maintainer of wget command line tool came as an attendee. Nice to see them working together on protocol details for their respective open source projects.

Overall the CURL project seems to work well. Activity is growing, more people contribute, the number of tests is growing and even the number of tests to source code lines is raising. They collect money via a donation service and plan to use it to fund a few things including some bug bounty program.

Looking forward to future events! Thanks everyone for organizing and interesting sessions.

Blog post about my presentation: Using system SSL Certificates in CURL

Required keys for info.plist file on Mac and iOS


When you build an application for MacOS or iOS, you may need to set some keys for info.plist. Apple requires for newer MacOS and iOS versions that applications have the info.plist entry and are code signed. If some malicious software would trick itself into getting loaded into a process and try to access your data, the app crashes if the entry is not in info.plist.

In FileMaker, you can add those entries right away in Xcode for your iOS app made with FileMaker iOS SDK. Sometimes for some things, you may even need to add the info.plist entries to the FileMaker Pro app itself.

In Xojo, you can create an info.plist file and drop into the project. Xojo will merge your info.plist file into the one for the application. This is a great way to automatically add the right entries. Other way is to use defaults app in a shell script, which can do that right away when you do code signing.

e.g. in a build script:
Dim App As String = CurrentBuildLocation + "/" + CurrentBuildAppName + ".app"
Call DoShellCommand("/usr/bin/defaults write " + App + "/Contents/Info ""NSCalendarsUsageDescription"" ""Exports events to your calendar.""")

The following table shows possible entries: (more)

Using system SSL Certificates in CURL


The CURL library supports various SSL backends. We build currently CURL in three variants. The main one uses OpenSSL cross platform. For Windows we build a second copy using Windows own SSL. For MacOS and iOS we build the third variant with transport security. The native SSL libraries from Mac and Windows use the certificates installed on the system, while we need to supply our own certificates for SSL with OpenSSL. You can download cacert.pem with common root certificates from CURL website. Or just use the certificate from your website if you only need to connect to the same server (certificate pinning). We need OpenSSL as SSH2 library uses it for the SSL part.

For MacOS we search the keychain for certificates. We copy the data for each certificate and use OpenSSL function d2i_X509 to parse it. Than we store it in a global std::vector.

For Windows, we open CA, AuthRoot and ROOT stores with CertOpenSystemStore function. We enumerate all certificates and add them to the same vector as for MacOS.

In CURL we use CURLOPT_SSL_CTX_FUNCTION option to set our callback. In the callback, we get the X509_STORE from the SSL context via SSL_CTX_get_cert_store function. We loop over our certificates and add each via X509_STORE_add_cert function. Now all certificates are loaded and we can enable verification.

Sample code: CURLSSLCertificatesWin.cpp and CURLSSLCertificatesMac.cpp.

In our Xojo plugin, simply call UseSystemCertificates method in CURLSMBS class to load certificates into this instance. In FileMaker, please call CURL.UseSystemCertificates function on the CURL session.

SetFrontMost for Windows


You may know the problem that on Windows your app shows several windows and some are behind others windows from other applications. The user may need to click once on all your app windows or use alt-tab key combination to switch to another app and back to get all windows to front.

We'll change that with our plugins by adding new functions to bring a windows app to the front. We activate the frontmost window from the app and arrange all other windows behind it, but before other windows.

For FileMaker Process.SetFrontMost function is now available for Windows in addition to MacOS. To bring an individual window to the front, you can use Window.Activate function.

For Xojo you can now set Application.FrontmostMBS property on Windows, too. We add window.ActivateWindowMBS method to bring a window to the front and set focus. For dealing with all windows on Windows, you can bring a window from another app to the front with ActivateWindow method in WindowsListMBS class.

We hope those two new functions will help you to improve the user experience in your solutions.
e.g. you can bring all windows to front when user clicks on one window.

Coming soon in April with MBS FileMaker Plugin 9.2 betas and MBS Xojo Plugins 19.2 betas.

10th birthday of MBS SQL Plugin


Our MBS SQL Plugin turns 10 years old today.

Over the years we got requests for alternative database plugin classes for use with Xojo (formerly REALbasic). In 2009 a client requested a native plugin for Microsoft SQL Server, so we started writing a SQL Plugin and got a deal with SQLAPI to use this C++ library as the base of the plugin. Over the years, we contributed lots of changes and bug fixes and helped funding adding CubeSQL and SQL Anywhere support to SQLAPI.

As of today, we support CubeSQL, Centura SQLBase, DB2, Firebird, Informix, InterBase, MariaDB, Microsoft Access, Microsoft SQL Server, MySQL, ODBC, Oracle Database Server, PostgreSQL, SQL Anywhere, SQLite, SQLCipher and Sybase. Well received features include using named parameters for prepared statements, full unicode support, threaded connect & execution, bulk row transfer, streaming blob values, and offering database specific options for advanced features.

You can use our plugin with one of two interfaces and even mix them. SQLConnectionMBS is our native interface for using all the nice features. This includes SQLCommandMBS class for doing both statement preparation and handling the result set. With SQLDatabaseMBS class, we have a database subclass, which makes transition easier for existing Xojo developers and use PreparedStatement interface and RecordSet class.

If you like to try the plugin, please check the website. Watch SQL Plugin presentation and read Xojo Developer Magazine article in issue 14.1.

The hotel offers the same rooms regularly for about $269 per night, so the rate is very good!

If you like to attend a conference, there is a the bigger official Xojo Developer Conference in May 2019 in Miami and our European Xojo conference in Cologne in October 2019.

As there is non XDC 2020 planned, if you though to skip 2019 and come next year, please reconsider. As posted in Xojo forum, Xojo Inc. does currently not plan with a XDC 2020 and we expect an announcement for a 2021 XDC later this year.

WWDC 2019


Today I got a notice from Apple that I won their ticket lottery and got a ticket for WWDC 2019 in San José.

I am looking forward to get into their keynote presentation, get into a few interesting session and meet a few of the engineer who wrote the frameworks I use everyday.

Anyone else coming to WWDC?

This is my 5th attempt to get a ticket for WWDC, so I am happy to get there this year.

I'll certainly add a few extra days to do the sight seeing tour to Apple's two campuses. Maybe I can even stop by FileMaker Inc. and take a look where they do all the development work?

If people are interested we could even make some kind of local meet-up with people from San Francisco or San José area to talk about FileMaker and Xojo?

CURL birthday and conference


Today CURL library and command line tool turns 21 years old. It's a long time in software business and a great success with curl on nearly every computer device on earth as it ships for example with MacOS, Google Chrome, Linux, Android and others.

Since January 2007 and the MBS Xojo Plugin 7.0, we do include CURL for up- and download via ftp/http.

Since January 2012 and the MBS FileMaker Plugin 2.5, we include CURL functions for FileMaker.

And as far as I see, FileMaker Inc. added CURL right to the database engine with version 11 of FileMaker, but only added CURL options for Insert From URL script step with version 16.

See blog post from Daniel Stenberg.

For end of March we have the CURL conference on the agenda in Prague. Please join it if you like to learn more about CURL. See wiki page.

Interested in a meeting for FileMaker or Xojo?
If you are in Prague and like to talk with me, please contact me soon.

SQLabs new website and products


Marco Bambini and his team worked hard on an update to their products CubeSQL Server, SQLiteManager and SQLiteDoctor.

During the past months we worked hard in order to renew the look and the functionalities of SQLabs and of all its products. We are extremely proud to announce a complete website renovation and products updates.

To celebrate the new updates we are offering a time limited, huge discount for all our products.

Read the details here.

MBS Xojo SQL Plugin and SQL Functions in MBS FileMaker Plugin supports CubeSQL Server and SQLite beside a dozen other database types.

Xojo Enterprise is now Xojo Pro Plus


Xojo Inc. changed the name of the license option called Enterprise to Xojo Pro Plus.



As you see, it includes Top Priority Support, so you get quicker answers from Xojo's support staff. Your messages and feedback cases should get priority to be read first. Fast Fixes are included, so your problems are not just read, but also bugs fixed and workarounds found to help your app to work. 2X Activations allows you to install Xojo on up to 6 computers or virtual machines. This is very handy to install Xojo Pro on Linux, MacOS and Windows VMs and activate Xojo there, so you can build and test easily on each machine.

Anyone who invests into Xojo Pro Plus licenses, should also consider to go to the Xojo Developer Conferences and talk directly to Xojo staff. Geoff Perlman will be at the conferences in Miami in May and in Cologne in October.

Track Line with Data Labels Retina


We like to show you this example project included with MBS Xojo ChartDirector Plugin. This example shows several features of ChartDirector and our plugin how to:
  • create a chart, here with lines.
  • use dates for an axis
  • use several data sets on a layer
  • use gradients for background color
  • handle mouse over for tracking
  • how to dynamically draw a layer on top fo the chart
  • how to do 2x resolution for support for HighDPI and Retina screens
  • how to handle fonts and show text on linux
  • how to format a label with custom font and formatting.
Check the example. You may need to enable HiDPI support option in shared build settings. Than you can build the project for Mac, Windows and Linux and it works nice in 32 and 64 bit.

MonkeyBread Software Releases the MBS Xojo Plugins in version 19.1


Nickenich, Germany - (March 12th, 2019) -- MonkeyBread Software today is pleased to announce MBS Xojo Plugins 19.1 for macOS, Linux and Windows, the latest update to their product that is easily the most powerful plugin collection currently available for Xojo. MBS Xojo Plugins have been updated and now includes over 2400 classes and 64000 documented features, and the versatile plugins have gained more new functions:

As you may know we have an existing BigNumberMBS class which provides a 320-bit floating point number. The new LargeNumberMBS class adds an integer with up to 4128 bits in size. That is enough bits for 1200 digits. You can generate big prime numbers, use normal math operators and bitwise operations.

Our DirectShow classes for recording video on Windows got upgraded. We now have a DirectShowAMVideoCompressionMBS class to configure video compression settings. Several classes got a ShowPropertyDialog method to show the standard configure dialog, so you can setup streams, camera controls, and video compression.

For SceneKit we added 28 new classes to handle basic geometry in 3D scenes, add actions, constrains and materials. We got a few nice example projects to show you how to construct items in 3D space and display them to the user.

The older NSUserNotificationMBS class got deprecated, so we added UNNotificationMBS and related classes for notifications on MacOS 10.14 or newer. This includes actions in the notifications, so user can respond directly.

For GraphicsMagick we got a new class to convert images threaded: GMConvertMBS and GM16ConvertMBS classes have properties for which image to load, what effect to apply and where to save it. As this works with preemptive threads, you can do various image operations in parallel to batch process a lot of images. Similar CGImageSourceMBS.CreateThumbnailMT method can create thumbnails using MacOS frameworks threaded.

We upgraded NSSpellCheckerMBS class for MacOS. The new NSTextCheckingResultMBS class provides details on all the issues found. This includes both grammar and spelling errors.

The new TextConverterMBS class converts between various text encodings, we got new UTF-8 related functions for StringHandleMBS class, we upgraded StoreKit classes for MacOS 10.14 with new subscription methods. For Linux we got a new LinuxIconMBS module to query file icons. For Windows we can now query all hard linked files to a given file path and TimerMBS class got an enabled property.

For SQLErrorExceptionMBS we now provide the SQL string causing the error, JSONMBS class got a new delete item method and PictureMBS has a new FilePath property for the temporary file used for memory mapping. NSColorSpaceMBS class can now tell you the file for a colorspace, PDFDocumentMBS class can now write file with options and TiffPictureMBS can query scanlines scaled down.

Finally we updated CURL to version 7.64.0, DynaPDF to version 4.0.26.75, SQLAPI to version 4.2.5 and SQLite to version 3.27.1.

See release notes for a complete list of changes. (more)

Simple load balancer for Xojo Web app


Recently we implemented some web applications for a client. We use cgi deployment with a linux server running apache, so the apache can handle the SSL stuff. If you have 20 people on one instance, it may get a bit slow for each user. To improve performance, we installed the application several times on the web server. For this we build the app several times with different app names and different identifiers. So we have MyApp1, MyApp2, MyApp3 and MyApp4. All have an unique identifier like com.company.myapp1 to 4. You can easily build that with a build script automatically.

 

Once you have all 4 copies of the app on the web server, you may need a little load balancing script. But first, each instance must be able to tell how many sessions it has, so we got a status query for the HandleSpecialURL event. The simple version looks like this:

 

EventHandler Function HandleSpecialURL(Request As WebRequest) As Boolean

#Pragma BackgroundTasks False

if Request.Path = "Status" then

Dim j As New JSONItem

Dim a As app = app

j.Value("MemoryUsed") = runtime.MemoryUsed

j.Value("ObjectCount") = runtime.ObjectCount

j.Value("SessionCount") = a.SessionCount

j.Value("Name") = a.ExecutableFile.Name

Request.Print j.ToString

return true

end if

End EventHandler
