To avoid name collisions, private tags should 10 # have names which begin with the developer's NetBSD login name 11 # followed by a - or _ character (e.g., thorpej_scsipi, 12 # thorpej-signal) 13 # 14 # Any branch or version tag not listed here should be assumed to be 15 # private to the developer who created it. It is inappropriate for 16 # anyone other than that developer to commit, move tags, or otherwise 17 # modify the contents of the branch. 18 # 19 # Please update this file when a new branch is ready for consumption 20 # by folks other than the maintainer, or when the use or status of an 21 # existing branch changes significantly. 22 # 23 # Format: 24 # Branch: name of branch 25 # Description: Purpose and intention of the branch 26 # Status: Active/Terminated/Dormant 27 # Start Date: date first instantiated 28 # End Date: date it was Terminated/made_Dormant, if any 29 # Base Tag: netbsd-1-5-base, etc. 30 # Maintainer: Somebody to blame. 31 # Scope: Portion of the tree covered. 32 # Notes: Various other info, perhaps explanation of special tags, 33 # who-may-commit policies, etc. 34 35 36 # Release branches: 37 38 Branch: comdex-fall-1999 39 Description: Special release branch for pre-1.5 release at 40 Fall 1999 COMDEX. 41 Status: Terminated 42 Start Date: 43 End Date: 44 Base Tag: comdex-fall-1999-base 45 Maintainer: ? 46 Scope: Entire tree. 47 Notes: 48 49 Branch: netbsd-0-9 50 Description: The NetBSD 0.9 release branch 51 Status: Terminated 52 Start Date: 53 End Date: 54 Base Tag: netbsd-0-9-base 55 Maintainer: Release Engineering <releng (a] netbsd.org> 56 Scope: Entire tree. 57 Notes: Subsidiary tags of: netbsd-0-9-ALPHA, netbsd-0-9-ALPHA2, 58 netbsd-0-9-BETA, netbsd-0-9-RELEASE. 59 Commits restricted to release engineering. 60 61 Branch: netbsd-1-0 62 Description: The NetBSD 1.0 release branch 63 Status: Terminated 64 Start Date: 65 End Date: 66 Base Tag: netbsd-1-0-base 67 Maintainer: Release Engineering <releng (a] netbsd.org> 68 Scope: Entire tree. 69 Notes: 70 Commits restricted to release engineering. 71 72 Branch: netbsd-1-1 73 Description: The NetBSD 1.1 release branch 74 Status: Terminated 75 Start Date: 76 End Date: 77 Base Tag: netbsd-1-1-base 78 Maintainer: Release Engineering <releng (a] netbsd.org> 79 Scope: Entire tree. 80 Notes: 81 Commits restricted to release engineering. 82 83 Branch: netbsd-1-2 84 Description: The NetBSD 1.2 release branch 85 Status: Terminated 86 Start Date: 87 End Date: 88 Base Tag: netbsd-1-2-base 89 Maintainer: Release Engineering <releng (a] netbsd.org> 90 Scope: Entire tree. 91 Notes: 92 Commits restricted to release engineering. 93 94 Branch: netbsd-1-3 95 Description: The NetBSD 1.3 release branch 96 Status: Terminated 97 Start Date: 98 End Date: 99 Base Tag: netbsd-1-3-base 100 Maintainer: Release Engineering <releng (a] netbsd.org> 101 Scope: Entire tree. 102 Notes: 103 Commits restricted to release engineering. 104 105 Branch: netbsd-1-4 106 Description: The NetBSD 1.4 release branch 107 Status: Active 108 Start Date: 1 Apr 2000 109 End Date: 110 Base Tag: netbsd-1-4-base 111 Maintainer: 1.4 Release Engineering <releng-1-4 (a] netbsd.org> 112 Scope: Entire tree. 113 Notes: 114 Commits restricted to release engineering. 115 116 Branch: netbsd-1-5 117 Description: The NetBSD 1.5 release branch 118 Status: Active 119 Start Date: 20 Jun 2000 120 End Date: 121 Base Tag: netbsd-1-5-base 122 Maintainer: 1.5 Release Engineering <releng-1-5 (a] netbsd.org> 123 Scope: Entire tree. 124 Notes: 125 Commits restricted to release engineering. 126 127 128 # Individual developers' branches: 129 130 131 Branch: bouyer-scsipi 132 Description: Integration of atapi support 133 Status: Terminated 134 Start Date: 135 End Date: 136 Base Tag: 137 Maintainer: Manuel Bouyer <bouyer (a] netbsd.org> 138 Scope: kernel 139 Notes: Superseded by thorpej_scsipi 140 141 Branch: chs-ubc 142 Description: ?

Also DEV_BSIZE would go away. 514 Status: Terminated 515 Start Date: Aug or Sept 1999 516 End Date: 1 Apr 2000 517 Base tag: wrstuden-devbsize-base 518 Maintainer: Bill Studenmund <wrstuden (a] netbsd.org> 519 Scope: kernel 520 Notes: No longer active due to lack of time, and introduction 521 of UBC. In terms of UBC, the primary cache for 522 file data is the VM cache, which needs to operate 523 in terms of VM pages. As no existing device has native 524 pages the same size as our VM pages, there already is 525 a mapping going on between the VM system and the 526 underlying blocks. So it would be easier and cleaner 527 to adjust that to deal w/ different block sizes. 528 Also with UBC, all i/o is in terms of bytes at an offset 529 with a certain length, so the exact block size isn't a big 530 deal. 531 532 Any other wrstuden-devbsize tag may (and should) go away. 533 534 535 536 # Other: 537 538 Branch: magnum 539 Description: ? 540 Status: ? 541 Start Date: 542 End Date: 543 Base Tag: magnum-base 544 Maintainer: ? 545 Scope: kernel 546 Notes: 547
