# Usage: diff_last_commits MY_WORKSPACE/../LAST_COMMITS [PATTERNS...]
|
|
#
|
|
# Diff git HEADs with a LAST_COMMITS file generated by another build
|
|
# Return true (0) if there are no differences
|
|
#
|
|
# PATTERNS may be used to filter out changes in some files when comparing
|
|
#
|
|
# If any file changed since LAST_COMMITs matches a PATTERN, we return
|
|
# false (ie changes detected & a rebuild is required). If it matches a
|
|
# "negative" pattern that begins with "!", we continue to the next file
|
|
# instead. Patterns are matched in order until a match is found. A
|
|
# combination of positive and negative patterns may be used to skip parts
|
|
# of the source tree.
|
|
#
|
|
# Patterns are similar to shell glob patterns, except "*" and "?" match
|
|
# any character including "/".
|
|
# Leading and trailing whitespace as well as leading "./" in patterns
|
|
# are not significant.
|
|
# Changes in files that didn't match any patterns are treated as positive
|
|
# matches.
|
|
#
|
|
# EXAMPLE:
|
|
#
|
|
# diff_last_commits $MY_WORKSPACE/../LAST_COMMITS \
|
|
# # detect changes in this file \
|
|
# "stx-tools/centos-mirror-tools/yum.conf.sample" \
|
|
# # ignore other changes under centos-mirror-tools \
|

# "!stx-tools/centos/mirror-tools/*" \
|
