Crittercism Joins the PLCrashReporter Consortium!

Plausible Labs is extremely pleased to announce that Crittercism has joined the PLCrashReporter Consortium, providing significant support for the ongoing open-source development of PLCrashReporter.

Plausible CrashReporter provides an open source in-process crash reporting framework for use on both the iPhone and Mac OS X, used by first-tier commercial crash reporting services like Crittercism.

Ongoing open source development work is sponsored directly by the members of the PLCrashReporter Consortium, as well as by individual application developers through our application developer support services.

Here at Plausible Labs, we’re big believers in the idea that complex development tools — such as compilers, debuggers, and crash reporters — benefit from being developed openly and under a liberal license, as to allow for wide adoption, peer review, and technical validation of the implementation across the widest possible user base. This development model has made PLCrashReporter one of the most reliable, well-architected, and feature-complete crash reporters available for iOS and Mac OS X.

We’ve laid out an ambitious project roadmap for this new year, starting with a few goals that we believe are imperative to growing PLCrashReporter’s utility and value:

  • Increase the scope and depth of useful data gathered in our crash reports, while maintaining our strict user privacy requirements.
  • Expand the user base of the library to ensure the continued health of the project.
  • Work with implementors of managed runtimes (such as Xamarin, Unity3d, RubyMotion, and RoboVM) to improve compatibility between PLCrashReporter and their managed runtime (some of which already use PLCrashReporter).
  • Maintain our focus on reliability by introducing technical solutions to provide even stronger reliability guarantees as the scope and complexity of the library continues to grow.
  • Improve usage and integration documentation, targeted at both 3rd party integrators, and application developers, to help encourage a healthy development ecosystem.

If your platform or application relies on PLCrashReporter, we’re always interested in hearing about your priorities, and your feedback on our roadmap. The support of existing and new sponsors makes an enormous difference in both the scope and scale of what we can produce, and the sponsorship of companies like Crittercism is imperative to the success of the project.


New Releases: PLBlocks 1.0 and PLCrashReporter 1.0 (and more!)

September 6th, 2009 / Announcements / Open Source
By: landonf

We’ve been working our way through our open source TODO list, and we’ve finished up some new releases of our projects that we’re pleased to announce:

PLBlocks 1.0

Plausible Blocks (PLBlocks) provides a drop-in runtime and toolchain for using blocks in iPhone 2.2+ and Mac OS X 10.5 applications. Both the runtime and compiler patches are direct backports from Apple’s Snow Leopard source releases.

The final 1.0 release includes two fixes for issues reported against the beta release:

  • Fixed support for using pre-compiled headers with blocks.
  • Work-around for rdar://7189835 – Xcode rewrites all occurrence of ‘gcc’ in a
    compiler path when linking using g++

We’re now using PLBlocks 1.0 for our own internal and client projects. The updated SDK is available for Leopard and Snow Leopard from the PLBlocks project page.

If you’d like to read more about using blocks in your own software, we recommend:

PLCrashReporter 1.0

Plausible CrashReporter provides an in-process crash reporting framework for use on both the iPhone and Mac OS X.

  • iPhone 3GS-optimized (armv7) binaries
  • Mac OS X 10.5+ PowerPC and experimental x86-64 support.

The latest release may be downloaded from the PLCrashReporter project page.

Since crash reports are handled internally to your iPhone application, it supports crash reporting for in-development application versions, allows users to provide additional feedback when submitting a report, and even provides the opportunity to inform users of known issues and the need to upgrade.

If you’d like to include PLCrashReporter in your own application, we recommend perusing some of the open-source usage examples:

PLDatabase 1.2.1

Plausible Database is an SQL database access library for Objective-C, initially focused on SQLite as an application database. The library supports both Mac OS X and iPhone development.

The new 1.2.1 release includes:

The latest release may be downloaded from the PLDatabase project page.

PLInstrument 1.0

This is the first release of PLInstrument, a reproducible instrumentation library modeled on xUnit. The library is intended to facilitate the instrumentation of performance critical code, and provide easily comparable results over the lifetime of the code base.

We use PLInstrument to provide reproducible measurements of performance critical sections in our applications and libraries.

The 1.0 release may be downloaded from the PLInstrument project page.

Example Usage

// If for some reason you wanted to measure the runtime of
// CGAffineTransform
- (PLInstrumentResult *) instrumentMirrorTransform {
    PLIAbsoluteTime start, finish;
    int iterations = 25000;

    start = PLICurrentTime();
    for (int i = 0 ; i < iterations; i++) {
        CGAffineTransform mirrorTransform;
        mirrorTransform = CGAffineTransformMakeTranslation(0.0, 200.0f);
        mirrorTransform = CGAffineTransformScale(mirrorTransform, 1.0, -1.0);
    finish = PLICurrentTime();

    return [PLInstrumentResult resultWithStartTime: start
                                           endTime: finish iterations: iterations];
