update: Update the files in a working copy with the latest version from a repository; lock: Lock files in a repository from being changed by other users; add: Mark specified files to be added to repository at next commit; remove: Mark specified files to be removed at next commit (note: keeps cohesive revision history of before and at the remove.)
ClearCase dynamic views are slower than local filesystems, even with a good network infrastructure. Repeated subsequent builds may run faster, due to build avoidance that is enabled by ClearCase's make substitute. Because MVFS requires server access every time a file is accessed, the performance of the file system depends on server capacity.
VFS for Git is designed to ease the handling of enterprise-scale Git repositories, such as the Microsoft Windows operating system (whose development switched to Git under Microsoft's internal "One Engineering System" initiative). The system exposes a virtual file system that only downloads files to local storage as they are needed.
File system corruption can frequently be repaired by the user or the system administrator. For example, a deleted file is typically not immediately overwritten on disk, but more often simply has its entry deleted from the file system index. In such a case, the deletion can be easily reversed.
To the applications, the file looks like an ordinary file with empty regions seen as regions filled with zeros; the file system maintains an internal list of such regions for each sparse file. [83] A sparse file does not necessarily include sparse zeros areas; the "sparse file" attribute just means that the file is allowed to have them.
The Unix kernel maintains internal consistency and runtime correctness with assertions as the fault detection mechanism. The basic assumption is that the hardware and the software should perform correctly and a failure of an assertion results in a panic , i.e. a voluntary halt to all system activity. [ 5 ]
In all Unix and Unix-like systems, as well as on Windows, each process has its own separate set of environment variables.By default, when a process is created, it inherits a duplicate run-time environment of its parent process, except for explicit changes made by the parent when it creates the child.
Alice and Bob have public key certificates issued by Carol, the certificate authority (CA).; Alice wishes to perform a transaction with Bob and sends him her certificate. Bob, concerned that Alice's private key may have been compromised, creates an 'OCSP request' that contains Alice's certificate serial number and sends it to Carol.
