Jeff King [Thu, 9 Jul 2009 06:37:35 +0000 (02:37 -0400)]
Makefile: install 'git' in execdir

When a git command executes a subcommand, it uses the "git
foo" form, which relies on finding "git" in the PATH.
Normally this should not be a problem, since the same "git"
that was used to invoke git in the first place will be
found.  And if somebody invokes a "git" outside of the PATH
(e.g., by giving its absolute path), this case is already
covered: we put that absolute path onto the front of PATH.

However, if one is using "sudo", then sudo will execute the
"git" from the PATH, but pass along a restricted PATH that
may not contain the original "git" directory. In this case,
executing a subcommand will fail.

To solve this, we put the "git" wrapper itself into the
execdir; this directory is prepended to the PATH when git
starts, so the wrapper will always be found.

git.c: avoid allocating one-too-many elements for new argv array

When creating a new argv array from a configured alias and the supplied
command line arguments, the new argv was allocated with one element too
many.  Since the first element of the original argv array is skipped when
copying it to the new_argv, the number of elements that are allocated
should be reduced by one.  'count' is the number of elements that new_argv
contains, and *argcp is the number of elements in the original argv array.
So the total allocation (including the terminating NULL entry) for the
new_argv array should be:

  count + (*argcp - 1) + 1

Also, the explicit assignment of the NULL terminating entry can be avoided
by just copying it over from the original argv array.

how much 'real development'" kind of statistics). And you can do it with
some fairly straightforward scripting, ie

git rev-list --parents HEAD |
grep ' .* ' |
git diff-tree --always -s --pretty=oneline --stdin |
less -S

will do it.

But I finally got irritated with the fact that we can skip merges with
'--no-merges', but we can't do the trivial reverse operation.

So this just adds a '--merges' flag that _only_ shows merges. Now you can
do the above with just a

git log --merges --pretty=oneline

which is a lot simpler. It also means that we automatically get a lot of

15 years agogit svn: Support multiple branch and tag paths in the svn repository.
Marc Branchaud [Tue, 23 Jun 2009 17:02:08 +0000 (13:02 -0400)]
git svn: Support multiple branch and tag paths in the svn repository.

This enables git-svn.perl to read multiple 'branches' and 'tags' entries in
svn-remote config sections.  The init and clone subcommands also support
multiple --branches and --tags arguments.

The branch (and tag) subcommand gets a new argument: --destination (or -d).
This argument is required if there are multiple branches (or tags) entries
configured for the remote Subversion repository.  The argument's value
specifies which branch (or tag) path to use to create the branch (or tag).
The specified value must match the left side (without wildcards) of one of
the branches (or tags) refspecs in the svn-remote's config.

revisions to be re-fetched.  Ideally SVN revs would be immutable,

15 years agogit-svn: let 'dcommit $rev' work on $rev instead of HEAD

git-svn: let 'dcommit $rev' work on $rev instead of HEAD

'git svn dcommit' takes an optional revision argument, but the meaning
of it was rather scary.  It completely ignored the current state of
the HEAD, only looking at the revisions between SVN and $rev.  If HEAD
was attached to $branch, the branch lost all commits $rev..$branch in
the process.

Considering that 'git svn dcommit HEAD^' has the intuitive meaning
"dcommit all changes on my branch except the last one", we change the
meaning of the revision argument.  git-svn temporarily checks out $rev
for its work, meaning that

* if a branch is specified, that branch (_not_ the HEAD) is rebased as
  part of the dcommit,

* if some other revision is specified, as in the example, all work
  happens on a detached HEAD and no branch is affected.

receive-pack: do not send error details to the client

If the objects that a client pushes to the server cannot be processed for
any reason, an error is reported back to the client via the git protocol.
We used to send quite detailed information if a system call failed if
unpack-objects is run. This can be regarded as an information leak. Now we
do not send any error details like we already do in the case where
index-pack failed.

Errors in system calls as well as the exit code of unpack-objects and
index-pack are now reported to stderr; in the case of a local push or via
ssh these messages still go to the client, but that is OK since these forms
of access to the server assume that the client can be trusted. If
receive-pack is run from git-daemon, then the daemon should put the error
messages into the syslog.

With this reasoning a new status report is added for the post-update-hook;
untrusted (i.e. daemon's) clients cannot observe its status anyway, others
may want to know failure details.
