core.excludesfile clean-up

There are inconsistencies in the way commands currently handle
the core.excludesfile configuration variable.  The problem is
the variable is too new to be noticed by anything other than
git-add and git-status.

 * git-ls-files does not notice any of the "ignore" files by
   default, as it predates the standardized set of ignore files.
   The calling scripts established the convention to use
   .git/info/exclude, .gitignore, and later core.excludesfile.

 * git-add and git-status know about it because they call
   add_excludes_from_file() directly with their own notion of
   which standard set of ignore files to use.  This is just a
   stupid duplication of code that need to be updated every time
   the definition of the standard set of ignore files is
   changed.

 * git-read-tree takes --exclude-per-directory=<gitignore>,
   not because the flexibility was needed.  Again, this was
   because the option predates the standardization of the ignore
   files.

 * git-merge-recursive uses hardcoded per-directory .gitignore
   and nothing else.  git-clean (scripted version) does not
   honor core.* because its call to underlying ls-files does not
   know about it.  git-clean in C (parked in 'pu') doesn't either.

We probably could change git-ls-files to use the standard set
when no excludes are specified on the command line and ignore
processing was asked, or something like that, but that will be a
change in semantics and might break people's scripts in a subtle
way.  I am somewhat reluctant to make such a change.

On the other hand, I think it makes perfect sense to fix
git-read-tree, git-merge-recursive and git-clean to follow the
same rule as other commands.  I do not think of a valid use case
to give an exclude-per-directory that is nonstandard to
read-tree command, outside a "negative" test in the t1004 test
script.

This patch is the first step to untangle this mess.

The next step would be to teach read-tree, merge-recursive and
clean (in C) to use setup_standard_excludes().

(a reasonably common configuration in the Subversion world) then one

Björn Steinbrink identified the "auto-prop" feature as the cause

Brian Downing noticed fast-import can produce tree depths of up
to 6,035 objects and even deeper.  Long delta chains can create
very small packfiles but cause problems during repacking as git
needs to unpack each tree to count the reachable blobs.

What's happening here is the active branch cache isn't big enough.
We're swapping out the branch and thus recycling the tree information
(struct tree_content) back into the free pool.  When we later reload
the tree we set the delta_depth to 0 but we kept the tree we just
reloaded as a delta base.

So if the tree we reloaded was already at the maximum depth we
wouldn't know it and make the new tree a delta.  Multiply the
number of times the branch cache has to swap out the tree times
max_depth (10) and you get the maximum delta depth of a tree created

Fix memory leak in traverse_commit_list

If we were listing objects too then the objects were buffered in an
array only reachable from a stack allocated structure.  When this
function returns that array would be leaked as nobody would have
a reference to it anymore.

Historically this hasn't been a problem as the primary user of
traverse_commit_list() (the noble git-rev-list) would terminate
as soon as the function was finished, thus allowing the operating
system to cleanup memory.  However we have been leaking this data
in git-pack-objects ever since that program learned how to run the
revision listing internally, rather than relying on reading object
names from git-rev-list.

To better facilitate reuse of traverse_commit_list during other
builtin tools (such as git-fetch) we shouldn't leak temporary memory
like this and instead we need to clean up properly after ourselves.

Our revision number sent to SVN is set to the last revision we
committed if we've made any previous commits in a dcommit
invocation.

Although our SVN Editor code uses the delta of two (old) trees
to generate information to send upstream, it'll still send
complete resultant files upstream; even if the tree they're
based against is out-of-date.

The combination of sending a file that does not include the
latest changes, but set with a revision number of a commit we
just made will cause SVN to accept the resultant file even if it
was generated against an old tree.

More trouble was caused when fixing this because we were
rebasing uncessarily at times.  We used git-diff-tree to check
the imported SVN revision against our HEAD, not the last tree we
committed to SVN.  The unnecessary rebasing caused merge commits
upstream to SVN to fail.

Linus Torvalds [Sat, 20 Oct 2007 19:31:31 +0000 (12:31 -0700)]
Fix diffcore-break total breakage

Ok, so on the kernel list, some people noticed that "git log --follow"
doesn't work too well with some files in the x86 merge, because a lot of
files got renamed in very special ways.

In particular, there was a pattern of doing single commits with renames
that looked basically like

 - rename "filename.h" -> "filename_64.h"
 - create new "filename.c" that includes "filename_32.h" or
   "filename_64.h" depending on whether we're 32-bit or 64-bit.

which was preparatory for smushing the two trees together.

Now, there's two issues here:

 - "filename.c" *remained*. Yes, it was a rename, but there was a new file
   created with the old name in the same commit. This was important,
   because we wanted each commit to compile properly, so that it was
   bisectable, so splitting the rename into one commit and the "create
   helper file" into another was *not* an option.

   So we need to break associations where the contents change too much.
   Fine. We have the -B flag for that. When we break things up, then the
   rename detection will be able to figure out whether there are better
   alternatives.

 - "git log --follow" didn't with with -B.

Now, the second case was really simple: we use a different "diffopt"
structure for the rename detection than the basic one (which we use for
showing the diffs). So that second case is trivially fixed by a trivial
one-liner that just copies the break_opt values from the "real" diffopts
to the one used for rename following. So now "git log -B --follow" works
fine:

diff --git a/tree-diff.c b/tree-diff.c
index 26bdbdd..7c261fd 100644
--- a/tree-diff.c
+++ b/tree-diff.c

  diff_opts.detect_rename = DIFF_DETECT_RENAME;
  diff_opts.output_format = DIFF_FORMAT_NO_OUTPUT;
  diff_opts.single_follow = opt->paths[0];
+ diff_opts.break_opt = opt->break_opt;
  paths[0] = NULL;
  diff_tree_setup_paths(paths, &diff_opts);
  if (diff_setup_done(&diff_opts) < 0)

however, the end result does *not* work. Because our diffcore-break.c
logic is totally bogus!

In particular:

 - it used to do

if (base_size < MINIMUM_BREAK_SIZE)
return 0; /* we do not break too small filepair */

   which basically says "don't bother to break small files". But that
   "base_size" is the *smaller* of the two sizes, which means that if some
   large file was rewritten into one that just includes another file, we
   would look at the (small) result, and decide that it's smaller than the
   break size, so it cannot be worth it to break it up! Even if the other
   side was ten times bigger and looked *nothing* like the samell file!

   That's clearly bogus. I replaced "base_size" with "max_size", so that
   we compare the *bigger* of the filepair with the break size.

 - It calculated a "merge_score", which was the score needed to merge it
   back together if nothing else wanted it. But even if it was *so*
   different that we would never want to merge it back, we wouldn't
   consider it a break! That makes no sense. So I added

if (*merge_score_p > break_score)
return 1;

   to make it clear that if we wouldn't want to merge it at the end, it
   was *definitely* a break.

 - It compared the whole "extent of damage", counting all inserts and
   deletes, but it based this score on the "base_size", and generated the
   damage score with

delta_size = src_removed + literal_added;
damage_score = delta_size * MAX_SCORE / base_size;

   but that makes no sense either, since quite often, this will result in
   a number that is *bigger* than MAX_SCORE! Why? Because base_size is
   (again) the smaller of the two files we compare, and when you start out
   from a small file and add a lot (or start out from a large file and
   remove a lot), the base_size is going to be much smaller than the
   damage!

   Again, the fix was to replace "base_size" with "max_size", at which
   point the damage actually becomes a sane percentage of the whole.

With these changes in place, not only does "git log -B --follow" work for
the case that triggered this in the first place, ie now

git log -B --follow arch/x86/kernel/vmlinux_64.lds.S

actually gives reasonable results. But I also wanted to verify it in
general, by doing a full-history

git log --stat -B -C

on my kernel tree with the old code and the new code.

There's some tweaking to be done, but generally, the new code generates
much better results wrt breaking up files (and then finding better rename
candidates). Here's a few examples of the "--stat" output:

 - This:
include/asm-x86/Kbuild        |    2 -
include/asm-x86/debugreg.h    |   79 +++++++++++++++++++++++++++++++++++------
include/asm-x86/debugreg_32.h |   64 ---------------------------------
include/asm-x86/debugreg_64.h |   65 ---------------------------------
4 files changed, 68 insertions(+), 142 deletions(-)

      Becomes:

include/asm-x86/Kbuild                        |    2 -
include/asm-x86/{debugreg_64.h => debugreg.h} |    9 +++-
include/asm-x86/debugreg_32.h                 |   64 -------------------------
3 files changed, 7 insertions(+), 68 deletions(-)

 - This:
include/asm-x86/bug.h    |   41 +++++++++++++++++++++++++++++++++++++++--
include/asm-x86/bug_32.h |   37 -------------------------------------
include/asm-x86/bug_64.h |   34 ----------------------------------
3 files changed, 39 insertions(+), 73 deletions(-)

      Becomes

include/asm-x86/{bug_64.h => bug.h} |   20 +++++++++++++-----
include/asm-x86/bug_32.h            |   37 -----------------------------------
2 files changed, 14 insertions(+), 43 deletions(-)

Now, in some other cases, it does actually turn a rename into a real
"delete+create" pair, and then the diff is usually bigger, so truth in
advertizing: it doesn't always generate a nicer diff. But for what -B was
meant for, I think this is a big improvement, and I suspect those cases
where it generates a bigger diff are tweakable.

So I think this diff fixes a real bug, but we might still want to tweak
the default values and perhaps the exact rules for when a break happens.

That happened in the case of a pathname that was ignored, and we did
not ask for "dir->show_ignored". That test used to be *together*
with the "DTYPE(de) != DT_DIR", but splitting the two tests up
means that we can do that (common) test before we even bother to
calculate the real dtype.

Of course, that optimization only matters for systems that don't
have, or don't fill in DTYPE properly.

I also clarified the real relationship between "exclude" and
"dir->show_ignored". It used to do

if (exclude != dir->show_ignored) {
..

which wasn't exactly obvious, because it triggers for two different
cases:

 - the path is marked excluded, but we are not interested in ignored
   files: ignore it

 - the path is *not* excluded, but we *are* interested in ignored
   files: ignore it unless it's a directory, in which case we might
   have ignored files inside the directory and need to recurse
   into it).

so this splits them into those two cases, since the first case
doesn't even care about the type.

I also made a the DT_UNKNOWN case a separate helper function,

git-gui: Correctly report failures from git-write-tree

If git-write-tree fails (such as if the index file is currently
locked and it wants to write to it) we were not getting the error
message as $tree_id was always the empty string so we shortcut
through the catch and never got the output from stderr.

17 years agosend-pack: respect '+' on wildcard refspecs

send-pack: respect '+' on wildcard refspecs

When matching source and destination refs, we were failing
to pull the 'force' parameter from wildcard refspecs (but
not explicit ones) and attach it to the ref struct.

This adds a test for explicit and wildcard refspecs; the
latter fails without this patch.

Paper bag fix diff invocation in 'git stash show'

In 89d750bf6fa025edeb31ad258cdd09a27a5c02fa I got a little too
aggressive with changing "git diff" to "git diff-tree".  This is
shown to the user, who expects to see a full diff on their console,
and will want to see the output of their custom diff drivers (if
any) as the whole point of this call site is to show the diff to
the end-user.
