* bisect: use "$GIT_DIR/BISECT_START" to check if we are bisectingChristian Couder2008-05-28
| | | | | | | | | | | | | | | | | | | It seems simpler and safer to use the BISECT_START file everywhere to decide if we are bisecting or not, instead of using it in some places and BISECT_NAMES in other places. In commit 6459c7c6786aa9bda0c7a095c9db66c36da0e5f0 (Nov 18 2007, Bisect: use "$GIT_DIR/BISECT_NAMES" to check if we are bisecting.), we decided to use BISECT_NAMES but code changed a lot and we now have to check BISECT_START first in the "bisect_start" function anyway. This patch also makes things a little bit safer by creating the BISECT_START file first and deleting it last, and also by adding checks in "bisect_clean_state".

* bisect: use a detached HEAD to bisectChristian Couder2008-05-22
| | | | | | | | | | | | | | | | | | | When "git bisect" was first written, it was not possible to checkout a detached HEAD. The detached feature appeared latter. That's why before this patch the "git bisect" process used a "bisect" branch to checkout new revisions to be tested (and also a "new-bisect" one to check if the checkouts could work). This patch makes "git bisect" checkout revisions to be tested on a detached HEAD. This simplifies the code a bit. The tests to check that "git bisect" does not start if a "bisect" or a "new-bisect" branch exists are removed as they are not relevant any more.

* bisect: trap critical errors in "bisect_start"Christian Couder2008-05-22
| | | | | | | | | | | | | | | | | | Before this patch, when using "git bisect start" with mistaken revs or when the checkout of the branch we want to test failed, we exited after having written files like ".git/BISECT_START", ".git/BISECT_NAMES" and after having written "refs/bisect/bad" and "refs/bisect/good-*" refs. With this patch we trap all errors that can happen when writing the new state and when we are in "bisect_next". So that we can try to clean up everything in case of problems, using "bisect_clean_state". This patch also contains a "bisect_write" cleanup to make it exit on error and return 0 otherwise.

* bisect: fix left over "BISECT_START" file when starting with junk revChristian Couder2008-05-22
| | | | | | | | | | | | | | | | | Before this patch, when using for example: $ git bisect start <stuff1> <stuff2> with <stuff1> or <stuff2> that cannot be parsed as a revision, we could leave a ".git/BISECT_START" file, from a previous "git bisect start", alone. This patch makes sure that it does not happen by removing the "BISECT_START" file in "bisect_clean_state" and then always writing it again at the end of "bisect_start".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a branch named "bisect" or "new-bisect" already was created in the repo by other means than git bisect, doing a git bisect used to override the branch without a warning. Now if the branch "bisect" or "new-bisect" already exists, and it was not created by git bisect itself, git bisect start fails with an appropriate error message. Additionally, if checking out a new bisect state fails due to a merge problem, git bisect cleans up the temporary branch "new-bisect".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this patch, when "git bisect start", "git bisect good" or "git bisect skip" were called with many revisions, they could fail after having already marked some revisions as "good", "bad" or "skip". This could be especilally bad for "git bisect start" because as the file ".git/BISECT_NAMES" would not have been written, there would have been no attempt to clear the marked revisions on a "git bisect reset". That's because if there is no ".git/BISECT_NAMES" file, nothing is done to clean things up, as the bisect session is not supposed to have started. While at it, let's also create the ".git/BISECT_START" file, only after ".git/BISECT_NAMES" as been created.

| | * bisect: squelch "fatal: ref HEAD not a symref" misleading messageChristian Couder2008-04-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To get the current HEAD when we start bisecting using for example "git bisect start", we first try "git symbolic-ref HEAD" to get a nice name, and if it fails, we fall back to "git rev-parse --verify HEAD". The problem is that when "git symbolic-ref HEAD" fails, it displays "fatal: ref HEAD not a symref", so it looks like "git bisect start" failed and does not accept detached HEAD, even if in fact it worked fine. This patch adds "-q" option to the "git symbolic-ref" call to get rid of the misleading error message.

This is because 'git rev-parse --revs-only --no-flags "$@"' always "exit 0" and outputs all the SHA1 it can found from parsing "$@". This patch fix this by using, for each "bisect good" argument, the same logic as for the "bisect bad" argument. While at it, this patch teaches "bisect bad" to give a meaningfull error message when it is passed more than one argument. Note that if "git bisect good" or "git bisect skip" is given some proper revs and then something that is not a proper rev, then the first proper revs will still have been marked as "good" or "skip".

There's no significant loss of safety here since we already have a general safety in the form of the reflog. Note: We preserve the warning for any cogito users.

That's why this patch adds a "git bisect help" subcommand that just calls "git bisect -h". This new subcommand is also fully documented in the short usage string (that "git bisect" gives), in the long usage string and in the man page (that "git help bisect" gives).

In System V, brackets are required (e.g., '[A-Z]'), whereas in POSIX they are not. We can mostly get around this by just using the bracket form for both sets, as in: tr '[A-Z] '[a-z]' in which case POSIX interpets this as "'[' becomes '['", which is OK. However, this doesn't work with multiple sequences, like: # rot13 tr '[A-Z][a-z]' '[N-Z][A-M][n-z][a-m]' where the POSIX version does not behave the same as the System V version. In this case, we must simply enumerate the sequence. This patch fixes problematic uses of tr in git scripts and test scripts in one of three ways: - if a single sequence, make sure it uses brackets - if multiple sequences, enumerate - if extra brackets (e.g., tr '[A]' 'a'), eliminate brackets Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

| | | | | | | | | | | | | | | | | | | | | | | | This teaches "git bisect visualize" to be more useful in non-windowed environments. (1) When no option is given, and $DISPLAY is set, it continues to spawn gitk as before; (2) When no option is given, and $DISPLAY is unset, "git log" is run to show the range of commits between the bad one and the good ones; (3) If only "-flag" options are given, "git log <options>" is run. E.g. "git bisect visualize --stat" (4) Otherwise, all of the given options are taken as the initial part of the command line and the commit range expression is given to that command. E.g. "git bisect visualize tig" will run "tig" history viewer to show between the bad one and the good ones. As "visualize" is a bit too long to type, we also give it a shorter synonym "view".

We don't always use "--bisect-all" because it is slower than "--bisect-vars" or "--bisect". When we cannot find for sure the first bad commit because of "skip"ped commits, we print the hash of each possible first bad commit and then we exit with code 2.

* git-bisect: modernizationJunio C Hamano2007-04-05
| | | | | | | This slightly modernizes the bisect script to use show-ref/for-each-ref instead of looking into $GIT_DIR/refs files directly. Signed-off-by: Junio C Hamano <junkio@cox.net>
* Bisect: teach "bisect start" to optionally use one bad and many good revs.Christian Couder2007-04-05
| | | | | | | | | | | | | | | | | | | | | | | | | One bad commit is fundamentally needed for bisect to run, and if we beforehand know more good commits, we can narrow the bisect space down without doing the whole tree checkout every time we give good commits. This patch implements: git bisect start [<bad> [<good>...]] [--] [<pathspec>...] as a short-hand for this command sequence: git bisect start git bisect bad $bad git bisect good $good1 $good2... On the other hand, there may be some confusion between revs (<bad> and <good>...) and <pathspec>... if -- is not used and if an invalid rev or a pathspec that looks like a rev is given.

* Bisect: Improve error message in "bisect_next_check".Christian Couder2007-03-29

* Bisect: add checks at the beginning of "git bisect run".Christian Couder2007-03-27
| | | | | | | | | | | | We may be able to "run" with only one good revision given and then verify that the result of the first run is bad. And perhaps also the other way around. But for now let's check that we have at least one bad and one good revision before we start to run.
