01:55 | Merge in small fixes to the test suite and plan to continue improving the suite in the trunk. Also kludge login.c on MinGW which has no strtok_r() available in its libc by supplying a public domain one. There certainly is a better way to deal with this, but this unbreaks the build on Windows broken by [315cf2436]. check-in: 93d52a01 user: rberteig tags: trunk | |

small and sometimes haphazard contributions. Fossil promotes a "cathedral" development model in which the project is closely supervised by an highly engaged architect and implemented by a clique of developers. Nota Bene: This is not to say that Git cannot be used for cathedral-style development or that Fossil cannot be used for bazaar-style development. They can be. But those modes are not their design intent nor the their low-friction path. Git encourages a style in which individual developers work in relative isolation, maintaining their own branches and occasionally rebasing and pushing selected changes up to the main repository. Developers using Git often have their own private branches that nobody else ever sees. Work becomes siloed. ................................................................................ Git was specifically designed to support the development of Linux. Fossil was specifically designed to support the development of SQLite. Both SQLite and Linux are important pieces of software. SQLite is found on far more systems than Linux. (Almost every Linux system uses SQLite, but there are many non-Linux systems such as iPhones, PlayStations, and Windows PC that use SQLite.) On the other hand, for those systems that do use Linux, Linux is a far more important component. Linux uses a bazaar-style development model. There are thousands and thousands of contributors, most of whom do not know each others names. Git is designed for this scenario. |

Fossil takes the philosophy of the <a href="http://en.wikipedia.org/wiki/The_Tortoise_and_the_Hare">tortoise</a>: reliability is more important than raw speed. The developers of fossil see no merit in getting the wrong answer quickly. Fossil may not be the fastest versioning system, but it is "fast enough".

These control artifacts define the relationships between artifacts - which files go together to form a particular version of the project, who checked in that version and when, what was the check-in comment, what wiki pages are included with the project, what are the edit histories of each wiki page, what bug reports or tickets are included, who contributed to the evolution of each ticket, and so forth. This low-level file format is called the "global state" of the repository, since this is the information that is synced to peer |
