This is the normal state. 17# 'alpha', 'alphadev' 18# The source is undergoing a series of alpha releases. 19# 'beta', 'betadev' 20# The source is undergoing a series of beta releases. 21# These states are computed from $PRE_LABEL and $TYPE 22# 23# The possible |next| values are: 24# 'alpha' The source tree should move to an alpha release state, or 25# stay there. This trips the alpha / pre-release counter. 26# 'beta' The source tree should move to a beta release state, or 27# stay there. This trips the beta / pre-release counter. 28# 'final' The source tree should move to a final release (assuming it's 29# currently in one of the alpha or beta states). This turns 30# off the alpha or beta states. 31# '' The source tree should move to the next release. The exact 32# meaning depends on the current source state. It may mean 33# tripping the alpha / beta / pre-release counter, or increasing 34# the PATCH number. 35# 36# 'minor' The source tree should move to the next minor version. This 37# should only be used in the master branch when a release branch 38# has been created. 39# 40# This function expects there to be a function called fixup_version(), which 41# SHOULD take the |next| as first argument, and SHOULD increase the label 42# counter or the PATCH number accordingly, but only when the current 43# state is "in development". 44 45next_release_state () { 46 local next="$1" 47 local today="$(date '+%-d %b %Y')" 48 local retry=true 49 50 local before="$PRE_LABEL$TYPE" 51 52 while $retry; do 53 retry=false 54 55 $DEBUG >&2 "DEBUG[next_release_state]: BEGIN: \$before=$before" 56 $DEBUG >&2 "DEBUG[next_release_state]: BEGIN: \$next=$next" 57 $DEBUG >&2 "DEBUG[next_release_state]: BEGIN: \$MAJOR=$MAJOR" 58 $DEBUG >&2 "DEBUG[next_release_state]: BEGIN: \$MINOR=$MINOR" 59 $DEBUG >&2 "DEBUG[next_release_state]: BEGIN: \$PATCH=$PATCH" 60 $DEBUG >&2 "DEBUG[next_release_state]: BEGIN: \$TYPE=$TYPE" 61 $DEBUG >&2 "DEBUG[next_release_state]: BEGIN: \$PRE_LABEL=$PRE_LABEL" 62 $DEBUG >&2 "DEBUG[next_release_state]: BEGIN: \$PRE_NUM=$PRE_NUM" 63 $DEBUG >&2 "DEBUG[next_release_state]: BEGIN: \$RELEASE_DATE=$RELEASE_DATE" 64 65 case "$before+$next" in 66 # MAKING ALPHA RELEASES ################################## 67 68 # Alpha releases can't be made from beta versions or real versions 69 beta*+alpha | +alpha ) 70 echo >&2 "Invalid state for an alpha release" 71 echo >&2 "Try --beta or --final, or perhaps nothing" 72 exit 1 73 ;; 74 # For alpha releases, the tag update is dev => alpha or 75 # alpha dev => alpha for the release itself, and 76 # alpha => alpha dev for post release. 77 dev+alpha | alphadev+alpha ) 78 TYPE= 79 RELEASE_DATE="$today" 80 fixup_version "alpha" 81 ;; 82 alpha+alpha ) 83 TYPE=dev 84 RELEASE_DATE= 85 fixup_version "alpha" 86 ;; 87 88 # MAKING BETA RELEASES ################################### 89 90 # Beta releases can't be made from real versions 91 +beta ) 92 echo >&2 "Invalid state for beta release" 93 echo >&2 "Try --final, or perhaps nothing" 94 exit 1 95 ;; 96 # For beta releases, the tag update is dev => beta1, or 97 # alpha{n}-dev => beta1 when transitioning from alpha to 98 # beta, or beta{n}-dev => beta{n} for the release itself, 99 # or beta{n} => beta{n+1}-dev for post release. 100 dev+beta | alphadev+beta | betadev+beta ) 101 TYPE= 102 RELEASE_DATE="$today" 103 fixup_version "beta" 104 ;; 105 beta+beta ) 106 TYPE=dev 107 RELEASE_DATE= 108 fixup_version "beta" 109 ;; 110 # It's possible to switch from alpha to beta in the 111 # post release.
