Cutelyst 0.11.0 released!

Cutelyst the Qt web framework just got a new release, I was planning to do this a while back, but you know we always want to put in a few more changes and time to do that is limited.

I was also interested in seeing if the improvements in Qt 5.6 would result in better benchmark tests but they didn’t, the hello world test app is probably too simple for the QString improvements to be noticed, a real world application using Grantlee views, Sql and more user data might show some difference. Still, compared to 0.10.0 Cutelyst is benchmarking the same even tho there were some small improvements.

The most important changes of this release were:

  • View::Email allows for sending emails using data provided on the stash, being able to chain the rendering of the email to another Cutelyst::View so for example you can have your email template in Grantlee format which gets rendered and sent via email (requires simple-mail-qt which is a fork of SmtpClient-for-Qt with a sane API, the View::Email hides simple-mail-qt API)
  • Utils::Sql provides a set of functions to be used with QSql classes, most importantly are serializing QSqlQuery to QVariantList of QVariantMap (or Hashes), allowing for accessing the query data on a View, and the preparedSqlQuery() method which comes with a macro CPreparedSqlQuery, that is a lambda that keeps your prepared statement into a static QSqlQuery, this avoids the need of QSqlQuery pointers to keep the prepared queries around (which are a boost for performance)
  • A macro CActionFor which resolves the Action into a static Action * object inside a lambda removing the need to keep resolving a name to an Action
  • Unit tests at the moment a very limited testing is done, but Header class has nearly 100% of coverage now
  • Upload parser got a fix to properly find the multipart boundary, spotted due Qt client sending boundaries a bit different from Chrome and FF, this also resulted in the removal of QRegularExpression to match the boundary part on the header with a simple search that is 5 times faster
  • Require Qt 5.5 (this allows for removal of workaround for QJson::fromHash and allows for the use of Q_ENUM and qCInfo)
  • Fixed crashes, and a memory leak is Stats where enabled
  • Improved usage of QStringLiteral and QLatin1String with clazy help
  • Added CMake support for setting the plugins install directory
  • Added more ‘const’ and ‘auto’
  • Removed uwsgi –cutelyst-reload option which never worked and can be replaced by –touch-reload and –lazy
  • Improvements and fixes on cutelyst command line tool
  • Many small bugs fixed

The Cutelyst website is powered by Cutelyst and CMlyst which is a CMS, at the moment porting CMlyst from QSettings to sqlite is on my TODO list but only when I figure out why out of the blue I get a “database locked” even if no other query is running (and yes I tried query.finish()), once I figure that out I’ll make a new CMlyst release.
