2008-02-13Add "--show-all" revision walker flag for debuggingLibravatar Linus Torvalds1-1/+3
It's really not very easy to visualize the commit walker, because - on purpose - it obvously doesn't show the uninteresting commits! This adds a "--show-all" flag to the revision walker, which will make it show uninteresting commits too, and they'll have a '^' in front of them (it also fixes a logic error for !verbose_header for boundary commits - we should show the '-' even if left_right isn't shown). A separate patch to gitk to teach it the new '^' was sent to paulus. With the change in place, it actually is interesting even for the cases that git doesn't have any problems with, ie for the kernel you can do: gitk -d --show-all v2.6.24.. and you see just how far down it has to parse things to see it all. The use of "-d" is a good idea, since the date-ordered toposort is much better at showing why it goes deep down (ie the date of some of those commits after 2.6.24 is much older, because they were merged from trees that weren't rebased). So I think this is a useful feature even for non-debugging - just to visualize what git does internally more. When it actually breaks out due to the "everybody_uninteresting()" case, it adds the uninteresting commits (both the one it's looking at now, and the list of pending ones) to the list This way, we really list *all* the commits we've looked at. Because we now end up listing commits we may not even have been parsed at all "show_log" and "show_commit" need to protect against commits that don't have a commit buffer entry. That second part is debatable just how it should work. Maybe we shouldn't show such entries at all (with this patch those entries do get shown, they just don't get any message shown with them). But I think this is a useful case. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2007-11-14Fix parent rewriting in --early-outputLibravatar Linus Torvalds1-8/+8
We cannot tell a node that has been checked and found not to be interesting (which does not have the TREECHANGE flag) from a node that hasn't been checked if it is interesting or not, without relying on something else, such as object->parsed. But an object can get the "parsed" flag for other reasons. Which means that "TREECHANGE" has the wrong polarity. This changes the way how the path pruning logic marks an uninteresting commits. From now on, we consider a commit interesting by default, and explicitly mark the ones we decided to prune. The flag is renamed to "TREESAME". Then, this fixes the logic to show the early output with incomplete pruning. It basically says "a commit that has TREESAME set is kind-of-UNINTERESTING", but obviously in a different way than an outright UNINTERESTING commit. Until we parse and examine enough parents to determine if a commit becomes surely "kind-of-UNINTERESTING", we avoid rewriting the ancestry so that later rounds can fix things up.

2007-11-11rev-list: Introduce --quiet to avoid /dev/null redirectsLibravatar Shawn O. Pearce1-4/+22
Some uses of git-rev-list are to run it with --objects to see if a range of objects between two or more commits is fully connected or not. In such a case the caller doesn't care about the actual object names or hash hints so formatting this data only for it to be dumped to /dev/null by a redirect is a waste of CPU time. If all the caller needs is the exit status then --quiet can be used to bypass the commit and object formatting. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
2007-11-05revision walker: mini clean-upLibravatar Linus Torvalds1-7/+7
This removes the unnecessary indirection of "revs->prune_fn", since that function is always the same one (or NULL), and there is in fact not even an abstraction reason to make it a function (i.e. its not called from some other file and doesn't allow us to keep the function itself static or anything like that). It then just replaces it with a bit that says "prune or not", and if not pruning, every commit gets TREECHANGE. That in turn means that - if (!revs->prune_fn || (flags & TREECHANGE)) - if (revs->prune_fn && !(flags & TREECHANGE)) just become - if (flags & TREECHANGE) - if (!(flags & TREECHANGE)) respectively. Together with adding the "single_parent()" helper function, the "complex" conditional now becomes if (!(flags & TREECHANGE) && rev->dense && single_parent(commit)) continue; Also indirection of "revs->dense" checking is thrown away the same way, because TREECHANGE bit is set appropriately now.

2007-06-30Don't fflush(stdout) when it's not helpfulLibravatar Theodore Ts'o1-1/+1
This patch arose from a discussion started by Jim Meyering's patch whose intention was to provide better diagnostics for failed writes. Linus proposed a better way to do things, which also had the added benefit that adding a fflush() to git-log-* operations and incremental git-blame operations could improve interactive respose time feel, at the cost of making things a bit slower when we aren't piping the output to a downstream program. This patch skips the fflush() calls when stdout is a regular file, or if the environment variable GIT_FLUSH is set to "0". This latter can speed up a command such as: GIT_FLUSH=0 strace -c -f -e write time git-rev-list HEAD | wc -l a tiny amount.

2007-06-13Lift 16kB limit of log message outputLibravatar Junio C Hamano1-3/+5
Traditionally we had 16kB limit when formatting log messages for output, because it was easier to arrange for the caller to have a reasonably big buffer and pass it down without ever worrying about reallocating. This changes the calling convention of pretty_print_commit() to lift this limit. Instead of the buffer and remaining length, it now takes a pointer to the pointer that points at the allocated buffer, and another pointer to the location that stores the allocated length, and reallocates the buffer as necessary. To support the user format, the error return of interpolate() needed to be changed. It used to return a bool telling "Ok the result fits", or "Sorry, I had to truncate it". Now it returns 0 on success, and returns the size of the buffer it wants in order to fit the whole result. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2007-04-17Make sure quickfetch is not fooled with a previous, incomplete fetch.Libravatar Junio C Hamano1-0/+4
This updates git-rev-list --objects to be a bit more careful when listing a blob object to make sure the blob actually exists, and uses it to make sure the quick-fetch optimization we introduced earlier is not fooled by a previous incomplete fetch. The quick-fetch optimization works by running this command: git rev-list --objects <<commit-list>> --not --all where <<commit-list>> is a list of commits that we are going to fetch from the other side. If there is any object missing to complete the <<commit-list>>, the rev-list would fail and die (say, the commit was in our repository, but its tree wasn't -- then it will barf while trying to list the blobs the tree contains because it cannot read that tree). Usually we do not have the objects (otherwise why would we fetching?), but in one important special case we do: when the remote repository is used as an alternate object store (i.e. pointed by .git/objects/info/alternates). We could check .git/objects/info/alternates to see if the remote we are interacting with is one of them (or is used as an alternate, recursively, by one of them), but that check is more cumbersome than it is worth. The above check however did not catch missing blob, because object listing code did not read nor check blob objects, knowing that blobs do not contain any further references to other objects. This commit fixes it with practically unmeasurable overhead. I've benched this with git rev-list --objects --all >/dev/null in the kernel repository, with three different implementations of the "check-blob". - Checking with has_sha1_file() has negligible (unmeasurable) performance penalty. - Checking with sha1_object_info() makes it somewhat slower, perhaps by 5%. - Checking with read_sha1_file() to cause a fully re-validation is prohibitively expensive (about 4 times as much runtime). In my original patch, I had this as a command line option, but the overhead is small enough that it is not really worth it. Signed-off-by: Junio C Hamano <junkio@cox.net>

2007-03-23Fix path-limited "rev-list --bisect" termination condition.Libravatar Junio C Hamano1-1/+1
In a path-limited bisection, when the $bad commit is not changing the limited path, and the number of suspects is 1, the code miscounted and returned $bad from find_bisection(), which is not marked with TREECHANGE. This is of course filtered by the output routine, resulting in an empty output, in turn causing git-bisect driver to say "$bad was both good and bad". Illustration. Suppose you have these four commits, and only C changes path P. You know D is bad and A is good. A---B---C*--D git-bisect driver runs this to find a bisection point: $ git rev-list --bisect A..D -- P which calls find_bisection() with B, C and D. The set of commits that is given to this function is the same set of commits as rev-list without --bisect option and pathspec returns. Among them, only C is marked with TREECHANGE. Let's call the set of commits given to find_bisection() that are marked with TREECHANGE (or all of them if no path limiter is in effect) "the bisect set". In the above example, the size of the bisect set is 1 (contains only "C"). For each commit in its input, find_bisection() computes the number of commits it can reach in the bisect set. For a commit in the bisect set, this number includes itself, so the number is 1 or more. This number is called "depth", and computed by count_distance() function. When you have a bisect set of N commits, and a commit has depth D, how good is your bisection if you returned that commit? How good this bisection is can be measured by how many commits are effectively tested "together" by testing one commit. Currently you have (N-1) untested commits (the tip of the bisect set, although it is included in the bisect set, is already known to be bad). If the commit with depth D turns out to be bad, then your next bisect set will have D commits and you will have (D-1) untested commits left, which means you tested (N-1)-(D-1) = (N-D) commits with this bisection. If it turns out to be good, then your next bisect set will have (N-D) commits, and you will have (N-D-1) untested commits left, which means you tested (N-1)-(N-D-1) = D commits with this bisection. Therefore, the goodness of this bisection is is min(N-D, D), and find_bisection() function tries to find a commit that maximizes this, by initializing "closest" variable to 0 and whenever a commit with the goodness that is larger than the current "closest" is found, that commit and its goodness are remembered by updating "closest" variable. The "the commit with the best goodness so far" is kept in "best" variable, and is initialized to a commit that happens to be at the beginning of the list of commits given to this function (which may or may not be in the bisect set when path-limit is in use). However, when N is 1, then the sole tree-changing commit has depth of 1, and min(N-D, D) evaluates to 0. This is not larger than the initial value of "closest", and the "so far the best one" commit is never replaced in the loop. When path-limit is not in use, this is not a problem, as any commit in the input set is tree-changing. But when path-limit is in use, and when the starting "bad" commit does not change the specified path, it is not correct to return it. Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-03-22git-rev-list --bisect: optimizationLibravatar Junio C Hamano1-2/+160
This improves the performance of revision bisection. The idea is to avoid rather expensive count_distance() function, which counts the number of commits that are reachable from any given commit (including itself) in the set. When a commit has only one relevant parent commit, the number of commits the commit can reach is exactly the number of commits that the parent can reach plus one; instead of running count_distance() on commits that are on straight single strand of pearls, we can just add one to the parents' count. On the other hand, for a merge commit, because the commits reachable from one parent can be reachable from another parent, you cannot just add the parents' counts up plus one for the commit itself; that would overcount ancestors that are reachable from more than one parents. The algorithm used in the patch runs count_distance() on merge commits, and uses the util field of commit objects to remember them. After that, the number of commits reachable from each of the remaining commits is counted by finding a commit whose count is not yet known but the count for its (sole) parent is known, and adding one to the parent's count, until we assign numbers to everybody. Another small optimization is whenever we find a half-way commit (that is, a commit that can reach exactly half of the commits), we stop giving counts to remaining commits, as we will not find any better commit than we just found. The performance to bisect between v1.0.0 and v1.5.0 in git.git repository was improved by saying good and bad in turns from 3.68 seconds down to 1.26 seconds. Bisecting the kernel between v2.6.18 and v2.6.20 was sped up from 21.84 seconds down to 4.22 seconds. Signed-off-by: Junio C Hamano <junkio@cox.net>

2006-09-05Teach rev-list an option to read revs from the standard input.Libravatar Junio C Hamano1-0/+25
When --stdin option is given, in addition to the <rev>s listed on the command line, the command can read one rev parameter per line from the standard input. The list of revs ends at the first empty line or EOF. Note that you still have to give all the flags from the command line; only rev arguments (including A..B, A...B, and A^@ notations) can be give from the standard input.

2006-09-02Replace uses of strdup with xstrdup.Libravatar Shawn Pearce1-2/+2
Like xmalloc and xrealloc xstrdup dies with a useful message if the native strdup() implementation returns NULL rather than a valid pointer. I just tried to use xstrdup in new code and found it to be missing. However I expected it to be present as xmalloc and xrealloc are already commonly used throughout the code. [jc: removed the part that deals with last_XXX, which I am finding more and more dubious these days.] Signed-off-by: Shawn O.

2006-08-27free(NULL) is perfectly valid.Libravatar Junio C Hamano1-4/+2
Jonas noticed some places say "if (X) free(X)" which is totally unnecessary. Signed-off-by: Junio C Hamano <junkio@cox.net>

[jc: I needed to hand merge the changes to the updated codebase, so the result needs to be checked.] Signed-off-by: David Rientjes <rientjes@google.com> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-07-29Call setup_git_directory() much earlierLibravatar Linus Torvalds1-2/+2
This changes the calling convention of built-in commands and passes the "prefix" (i.e. pathname of $PWD relative to the project root level) down to them. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
