Another approach is to split a branch off the trunk, implement changes in that branch and merge the changes back into the trunk when the branch has proven to be stable and working. Depending on development mode and commit policy the trunk may contain the most stable or the least stable or something-in-between version.
Manual merging is also required when automatic merging runs into a change conflict; for instance, very few automatic merge tools can merge two changes to the same line of code (say, one that changes a function name, and another that adds a comment). In these cases, revision control systems resort to the user to specify the intended merge result.
A pull request, a.k.a. merge request, is a request by a user to merge a branch into another branch. [118] [119] Git does not itself provide for pull requests, but it is a common feature of git cloud services. The underlying function of a pull request is no different than that of an administrator of a repository pulling changes from another ...
Usage of Last Branch Records, [7] a branch tracing implementation available in Intel CPUs since Pentium 4, is available as a patch. [6] Since version 3.14 of the Linux kernel mainline , released on March 31, 2014, perf also supports running average power limit (RAPL) for power consumption measurements, which is available as a feature of certain ...
Loop unrolling, also known as loop unwinding, is a loop transformation technique that attempts to optimize a program's execution speed at the expense of its binary size, which is an approach known as space–time tradeoff.
The kernel maintains a master-region table and many per-process-region (pregion) tables—one for each running process. [133] These tables constitute the virtual address space. The master-region table is used to determine where its contents are located in physical memory. The pregion tables allow each process to have its own program (text ...
CouchDB is well suited for applications with accumulating, occasionally changing data, on which pre-defined queries are to be run and where versioning is important (CRM, CMS systems, by example). Master-master replication is an especially interesting feature, allowing easy multi-site deployments. [14]
Some distributions like Debian tend to separate tools into different packages – usually stable release, development release, documentation and debug. Also counting the source package number varies. For debian and rpm based entries it is just the base to produce binary packages, so the total number of packages is the number of binary packages.
