Finishing patches makes them permanent changesets. Finish first applied patch in the queue: hg qfinish Finish all applied patches in the queue: hg qfinish -a

To fold (combine) two patches: hg qnew firstPatch // Create first patch hg qnew secondPatch // Create second patch hg qpop // Pop secondPatch hg qfold secondPatch // Fold secondPatch with firstPatch

Functional tests are best described as tests for your user stories. If you've dealt with user stories before they normally follow the following pattern: As a [role], I want to [desire], so that [benefit/desired outcome] For the following examples we'll use this user story as an example: As a Du...

DateTimeField is used to store date time values. class MyModel(models.Model): start_time = models.DateFimeField(null=True, blank=True) created_on = models.DateTimeField(auto_now_add=True) updated_on = models.DateTimeField(auto_now=True) A DateTimeField has two optional parameters:...

The predicate function matches can be used to evaluate strings on the fly without use of any object declarations. IF matches( val = 'Not a hex string' regex = '[0-9a-f]*' ). cl_demo_output=>display( 'This will not display' ). ELSEIF matches( val = '6c6f7665' reg...

As already pointed out in other pitfalls, catching all exceptions by using try { // Some code } catch (Exception) { // Some error handling } Comes with a lot of different problems. But one perticular problem is that it can lead to deadlocks as it breaks the interrupt system when writ...

The latest version of the Oracle Java style guide mandates that the "then" and "else" statements in an if statement should always be enclosed in "braces" or "curly brackets". Similar rules apply to the bodies of various loop statements. if (a) { //...

The Symbol.for method allows you to register and look up global symbols by name. The first time it is called with a given key, it creates a new symbol and adds it to the registry. let a = Symbol.for('A'); The next time you call Symbol.for('A'), the same symbol will be returned instead of a new o...

For more complex applications, flat execution profiles may be difficult to follow. This is why many profiling tools also generate some form of annotated callgraph information. gperf2dot converts text output from many profilers (Linux perf, callgrind, oprofile etc.) into a callgraph diagram. You can...

Google Perf Tools also provides a CPU profiler, with a slightly friendlier interface. To use it: Install Google Perf Tools Compile your code as usual Add the libprofiler profiler library to your library load path at runtime Use pprof to generate a flat execution profile, or a callgraph diagram...
