that's an illogical thing to do, since "git show" is defined to be a

and wrong. The fact that we happily accept it (and then _only_ show
v1.5.0, which is the positive end of the range) is quite arguably not very
logical.
We should complain, and say that you can only do "no_walk" with positive
refs. Negative object refs really don't make any sense unless you walk
the obejct list (or you're "git diff" and know about ranges explicitly).

cvsserver: Make always-binary mode a config file option
The config option gitcvs.allbinary may be set to force all entries to
get the -kb flag.
In the future the gitattributes system will probably be a more
appropriate way of doing this, but that will easily slot in as the
entries lines sent to the CVS client now have their kopts set via the
function kopts_from_path().
In the interim it might be better to not just have a all-or-nothing
approach, but rather detect based on file extension (or file contents?).
That would slot in easily here as well. However, I personally prefer
everything to be binary-safe, so I just switch the switch.

cvsserver: Remove trailing "\n" from commithash in checkin function
The commithash for updating the ref is obtained from a call to
git-commit-tree. However, it was returned (and stored) with the
trailing newline. This meant that the later call to git-update-ref that
was trying to update to $commithash was including the newline in the
parameter - obviously that hash would never exist, and so git-update-ref
would always fail.
The solution is to chomp() the commithash as soon as it is returned by
git-commit-tree.

Make 'cvs ci' lockless in git-cvsserver by using git-update-ref
This makes "ci" codepath lockless by following the usual
"remember the tip, do your thing, then compare and swap at the
end" update pattern using update-ref. Incidentally, by updating
the code that reads where the tip of the head is to use
show-ref, it makes it safe to use in a repository whose refs are
pack-pruned.
I noticed that other parts of the program are not yet pack-refs
safe, but tried to keep the changes to the minimum.
This function is called only once in the whole source tree. Let's move
its code inline instead, which is also in the spirit of removing as much
object type char arrays as possible (not that this patch does anything for
that but at least it is now a local matter).

convert object type handling from a string to a number
We currently have two parallel notation for dealing with object types
in the code: a string and a numerical value. One of them is obviously
redundent, and the most used one requires more stack space and a bunch
of strcmp() all over the place.
This is an initial step for the removal of the version using a char array
found in object reading code paths. The patch is unfortunately large but
there is no sane way to split it in smaller parts without breaking the
system.

First there are too many offsets there and it is getting confusing.
So 'offset' is now 'curpos' to distinguish from other offsets like
'obj_offset'.
Then structures like x = foo(x, &y) are now done as y = foo(&x).
It looks more natural that the result y be returned directly and
x be passed as reference to be updated in place. This has the effect
of reducing some line length and removing a few, needing a bit less
stack space, and it even reduces the compiled code size.

Let's have hdr be a simple char pointer/array when possible, and let's
reduce its storage to 32 bytes. Especially for sha1_loose_object_info()
where 128 bytes is way excessive and wastes extra CPU cycles inflating.
The object type is already restricted to 10 bytes in parse_sha1_header()
and the size, even if it is 64 bits, will fit in 20 decimal numbers. So
32 bytes is plenty.

git-apply: do not fix whitespaces on context lines.
Internal function apply_line() is called to copy both context lines
and added lines to the output buffer, while possibly fixing the
whitespace breakages depending on --whitespace=strip settings.
However, it did its fix-up on both context lines and added lines.
This resulted in two symptoms:
(1) The number of lines reported to have been fixed up included
these context lines.
(2) However, the lines actually shown were limited to the added
lines that had whitespace breakages.
diff --cc: integer overflow given a 2GB-or-larger file
Few of us use git to compare or even version-control 2GB files,
but when we do, we'll want it to work.
Reading a recent patch, I noticed two lines like this:
int len = st.st_size;
Instead of "int", that should be "size_t". Otherwise, in the
non-symlink case, with 64-bit size_t, if the file's size is 2GB,
the following xmalloc will fail:
result = xmalloc(len + 1);
trying to allocate 2^64 - 2^31 + 1 bytes (assuming sign-extension
in the int-to-size_t promotion). And even if it didn't fail, the
subsequent "result[len] = 0;" would be equivalent to an unpleasant
"result[-2147483648] = 0;"
The other nearby "int"-declared size variable, sz, should also be of
type size_t, for the same reason. If sz ever wraps around and becomes
negative, xread will corrupt memory _before_ the "result" buffer.

It basically considers all the continuation lines to be lines of their

diff sets the exit status to 0 when no changes were found, to 1

We imitate this to be able to use "git diff" in the test scripts.
(Actually, keeping in line with the rest of git, -1 is returned
on error, which corresponds to an exit status 255).

diff --cc: fix display of symlink conflicts during a merge.

the correct mode information for the working tree down, and showed
bogus combined diff.
merge-recursive: fix longstanding bug in merging symlinks
Commit 3af244ca added unlink(2) before running symlink(2) to
update the working tree with the merge result, but it was
unlinking a wrong path. This resulted in loss of the path
pointed by a symlink.

Ancient commit e2b6a9d0 added code to pass "file modes" from
merge-index to merge-one-file, and then later commit 54dd99a1
wanted to make sure we do not end up creating a nonsense symlink
that points at a path whose name contains conflict markers.
However, nobody noticed that the code in merge-index added by e2b6a9d0 were stripping the S_IFMT bits and the code in 54dd99a1
was meaningless. This fixes it.

Allow arbitrary number of arguments to git-pack-objects
If a repository ever gets in a situation where there are too many
packs (more than 60 or so), perhaps because of frequent use of
git-fetch -k or incremental git-repack, then it becomes impossible to
fully repack the repository with git-repack -a. That command just
dies with the cryptic message
fatal: too many internal rev-list options
This message comes from git-pack-objects, which is passed one command
line option like --unpacked=pack-<SHA1>.pack for each pack file to be
repacked. However, the current code has a static limit of 64 command
line arguments and just aborts if more arguments are passed to it.
Fix this by dynamically allocating the array of command line
arguments, and doubling the size each time it overflows.

git-svn: fix some potential bugs with --follow-parent
When using do_switch:
We only need to ensure the index is clean and set to that of the
parent tree) we rely on being able to reconstruct full files
with deltas transferred over the network.
When using do_update:
We may safely unlink the index if we are fetching an entire
new tree with do_update. Having an old index (from a
previously deleted/abandoned directory) around can cause
irrelevant files to be mistakenly kept.
git-svn: fix reconnections to different paths of svn:// repositories
Clearing the pool of the previous SVN::Ra connection we have
seems to to fix mysterious connection dropping errors when
reconnecting to different paths of svn:// repositories hosted by
rubyforge.org.
Note: I'm not sure *why* this fixes things things,
but it does for me.
git-svn: don't consider SVN URL usernames significant when comparing
http://foo@blah.com/path is the same as http://blah.com/path, so
remove usernames from URLs before storing them in commits, and when
reading them from commits.
git-svn: ensure we're at the top-level and can access $GIT_DIR
If we are run inside a subdirectory of a working tree, we'll
chdir to the top first before touching anything. This also
prevents the accidental creation of .git directories inside
subdirectories since they need metadata.
git-svn: give show-ignore HEAD smarts, like dcommit and log
This allows the user to run git-svn show-ignore on there
current HEAD without needing to remember which branch/ref they
branched from with -i. Also, find_by_url should correctly
handle cases where the URL passed to it is not valid.
git-svn: allow metadata options to be specified with 'init' and 'clone'
Since the options that affect the way metadata is handled in
git-svn, should be consistently set/unset throughout history
imported by git-svn; it makes sense to allow the user to set
certain options from the command-line that will write to the
config file when initially creating the repository.
Also, fix some formatting issues while we're updating
documentation.
This documents the 'clone' and 'rebase' commands
of git-svn. Additionaly, examples are updated
to use them instead of the lower-level 'init' and
'fetch' commands.
These tests are very similar as the ones I used for useSvmProps
and expect the same results because both dumps were generated
from the same original repo.
git-svn: fix useSvmProps, hopefully for the last time
svm:mirror is not useful at all for us. Parts of the old unit
test were broken and based on my misunderstanding of the
svm:mirror property.
When we read svm:source; make sure we correctly handle the '!'
in it: it is used to separate the path of the repository root
from the virtual path within the repository. We don't need
to make that distinction, honestly!
We also ensure that subdirectories are also mirrored with the
correct URL if we're using useSvmProps.
We have a new test that uses dumped repo that was really
created using SVN::Mirror to avoid ambiguities and
mis-understandings about the svm: properties.
Note: trailing whitespace in the svm.dump file is unfortunately
a reality and required by SVN; so please ignore it when applying
this patch.
Also, ensure that the -R/--remote/--svn-remote flag is always
in effect if explicitly passed via the command-line. This
allows us to track logically different mirrors sharing the
same URL (probably common with SVN::Mirror/SVK users).
This is similar to useSvmProps, but far simpler in
implementation because svnsync retains a 1:1
between revision numbers and relative paths within
the repository
git-svn: allow overriding of the SVN repo root in metadata
This feature allows users to create repositories from alternate
URLs. For example, an administrator could run git-svn on the
server locally (accessing via file://) but wish to distribute
the repository with a public http:// or svn:// URL in the
metadata so users of it will see the public URL.
This works similarly to 'svn update' or 'git pull' except that
it preserves linear history with 'git rebase' instead of 'git
merge' for ease of dcommit-ing with git-svn.
While we're at it, put the working_head_info() logic
into its own function and allow --fetch-all/--all for
dcommit and rebase (which will fetch all refs in the
current [svn-remote] instead of just the working one).
Note that the '-a' switch (short for --fetch-all/--all) has been
removed as it conflicts with the non-svn 'git fetch'
On newly-created repositories, 'refs/heads/master' does not
point to anything. This can be confusing to new users; so we
update 'master' to point to the last imported ref after fetching
is done.
Once 'master' is valid; we assume HEAD points to it; and if
the repository is not bare, then checkout the files if the
working tree is clean and unused.
git-svn: allow dcommit for those who only fetch from SVM with useSvmProps
This allows users to use SVM (SVN::Mirror) to mirror a remote
repository to use dcommit to commit to the repository that SVM
was mirroring. When dcommit is used in this manner, the automatic
fetch + rebase/reset does not happen; in which case the user will
have to manually invoke svm/svk, run 'git svn fetch', and finally
'git rebase'.
git-svn: allow --log-window-size to be specified, default to 100
The newer default value should should lower memory usage for
large fetches and also help with fetching from less reliable
servers. Previously the value was 1000 and memory usage
got a bit high on some repositories and fetching became
less reliable in some cases.
git-svn: hopefully make 'fetch' more user-friendly
multi-fetch is deprecated, "fetch -a" is easier to type
By default, fetch will fetch everything from its default
[svn-remote]; if fetch [--all|-a] is specified, then it will
fetch from all svn remotes. Refspecs on the command-line
(like git-fetch) are not supported.
Also, enable -r/--revision arguments for fetch so
users can shoot themselves in the foot^W^W^W^W^W
skip some history and do the equivalent of a shallow
clone/fetch they're not interested in.
t910*: s/repo-config/config/g; poke around possible race conditions
Some of the repo-config => config renaming missed the git-svn
tests; so I'm just renaming them to be consisten with the
rest of the modern git.
Also, some of the newer tests didn't have 'poke' in them
to workaround race conditions on fast machines. This adds
places where they can _possibly_ occur; but I don't have
fast enough hardware to trigger them.
git-svn: usability fixes for the 'git svn log' command
Similar in spirit to the recent dcommit change, we now
look at 'HEAD' by default to look for a GIT_SVN_ID
so the user won't have to pass -i <GIT_SVN_ID> argument.
We are also more tolerant of of people passing bare remote names
as a result (just $GIT_SVN_ID without the -i)
* dcommit no longer requires the correct -i/GIT_SVN_ID option
passed to it. Since you're committing from HEAD (or another
commit that is a parent of HEAD), you'll be able to find
a commit with metadata information containing the SVN URL
that your HEAD was descended from anyways.
* I don't think dcommit ever worked for people using the
noMetadata option; so I don't think relying on metadata
is an issue.
* useSvmProps users shouldn't commit to SVN::Mirror created
repositories anyways, right?
* Users of globbing should automatically be able to commit
to paths that are not explicitly set in .git/config
A manual test that sets up a repository that looks like an SVK depot,
and then imports it to check that it looks like we mirrored the
'original' source.
There is also a minor modification to the git-svn test library shell
file which sets a variable for the subversion repository's filesystem
path.
[ew: made some of the tests stricter and more thorough]
git-svn: handle multi-init without --trunk, UseSvmProps fixes
multi-init did not write a svn-remote.<remote>.url config
entry without a --trunk argument.
Also, The svm:mirror property is used by SVN::Mirror to track
the path of the repository that we are mirroring. We need to
append that to the source (which is (presumably) just the URL of
the repository root).
Lastly, we now look harder for svm:(source|mirror|uuid) properties
in sub and parent directories. Since our relative path could
be tweaked.
git-svn: write the highest maxRex out for branches and tags
Even if nothing touched paths we care about in a fetch;
increment the maxRev like we do with rev_db since
we don't like having to run get_log on revisions we've
seen before.
