2009-04-07rev-list: add "int bisect_show_flags" in "struct rev_list_info"Libravatar Christian Couder1-2/+2
This is a cleanup patch to make it easier to use the "show_bisect_vars" function and take advantage of the rev_list_info struct. Signed-off-by: Christian Couder <chriscool@tuxfamily.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-04-07rev-list: remove last static vars used in "show_commit"Libravatar Christian Couder1-1/+5
This patch removes the last static variables that were used in the "show_commit" function. To do that, we create a new "rev_list_info" struct that we will pass in the "void *data" argument to "show_commit". This means that we have to change the first argument to "show_bisect_vars" too. While at it, we also remove a "struct commit_list *list" variable in "cmd_rev_list" that is not really needed.

2009-04-05bisect--helper: string output variables together with "&&"Libravatar Christian Couder1-1/+2
When doing: eval "git bisect--helper --next-vars" | { while read line do echo "$line &&" done echo ':' } the result code comes from the last "echo ':'", not from running "git bisect--helper --next-vars". This patch gets rid of the need to string together the line from the output of "git bisect--helper" with "&&" in the calling script by making "git bisect--helper --next-vars" return output variables already in that format.

2009-04-05rev-list: pass "int flags" as last argument of "show_bisect_vars"Libravatar Christian Couder1-1/+1
Instead of "int show_all, int show_tried" we now only pass "int flags", because we will add one more flag in a later patch. Signed-off-by: Christian Couder <chriscool@tuxfamily.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-04-05bisect: implement "read_bisect_paths" to read paths in "$GIT_DIR/BISECT_NAMES"Libravatar Christian Couder1-9/+46
This is needed because "git bisect--helper" must read bisect paths in "$GIT_DIR/BISECT_NAMES", so that a bisection can be performed only on commits that touches paths in this file. Signed-off-by: Christian Couder <chriscool@tuxfamily.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-04-05bisect--helper: implement "git bisect--helper"Libravatar Christian Couder1-0/+68
This patch implements a new "git bisect--helper" builtin plumbing command that will be used to migrate "git-bisect.sh" to C. We start by implementing only the "--next-vars" option that will read bisect refs from "refs/bisect/", and then compute the next bisect step, and output shell variables ready to be eval'ed by the shell. At this step, "git bisect--helper" ignores the paths that may have been put in "$GIT_DIR/BISECT_NAMES". This will be fixed in a later patch.

2009-04-05bisect: use the new generic "sha1_pos" function to lookup sha1Libravatar Christian Couder1-14/+9
instead of the specific one that was simpler but less efficient. Signed-off-by: Christian Couder <chriscool@tuxfamily.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-04-05rev-list: call new "filter_skip" functionLibravatar Christian Couder1-0/+63
This patch implements a new "filter_skip" function in C in "bisect.c" that will later replace the existing implementation in shell in "git-bisect.sh". An array is used to store the skipped commits. But the array is not yet fed anything. Signed-off-by: Christian Couder <chriscool@tuxfamily.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-03-30rev-list: move bisect related code into its own fileLibravatar Christian Couder1-0/+388
This patch creates new "bisect.c" and "bisect.h" files and move bisect related code into these files. While at it, we also remove some include directives that are not needed any more from the beginning of "builtin-rev-list.c".
