    To commit a change in git on the command line, assuming git is installed, the following command is run: [1] git commit -m 'commit message' This is also assuming that the files within the current directory have been staged as such: [2] git add . The above command adds all of the files in the working directory to be staged for the git commit.

    Git does periodic repacking automatically, but manual repacking is also possible with the git gc command. [46] For data integrity, both the packfile and its index have an SHA-1 checksum [47] inside, and the file name of the packfile also contains an SHA-1 checksum. To check the integrity of a repository, run the git fsck command. [48] [49]

    In Python, functions are first-class objects that can be created and passed around dynamically. Python's limited support for anonymous functions is the lambda construct. An example is the anonymous function which squares its input, called with the argument of 5:

  6. Command pattern - Wikipedia

    For example, to undo a delete selection command, the object may contain a copy of the deleted text so that it can be re-inserted, if the delete selection command must be undone. Note that using a separate object for each invocation of a command is also an example of the chain of responsibility pattern. The term execute is also ambiguous.

    en.wikipedia.org/wiki/Intentional_programming

    For example, in many current code collaboration systems (e.g. Git), when two programmers commit changes that conflict (i.e. if one programmer renames a function while another changes one of the lines in that function), the versioning system will think that one programmer created a new function while another modified an old function. In an IP ...

  8. Delta encoding - Wikipedia

    en.wikipedia.org/wiki/Delta_encoding

    A delta can be defined in 2 ways, symmetric delta and directed delta.A symmetric delta can be expressed as (,) = (),where and represent two versions.. A directed delta, also called a change, is a sequence of (elementary) change operations which, when applied to one version , yields another version (note the correspondence to transaction logs in databases).

    Example of a signed repository key (with ZYpp on openSUSE) As software repositories are designed to include useful packages, major repositories are designed to be malware free. If a computer is configured to use a digitally signed repository from a reputable vendor, and is coupled with an appropriate permissions system , this significantly ...
