13 years agodescribe: Refresh the index when run with --dirty
Allan Caffee [Mon, 1 Aug 2011 01:52:41 +0000 (21:52 -0400)]
describe: Refresh the index when run with --dirty

When running git describe --dirty the index should be refreshed.  Previously
the cached index would cause describe to think that the index was dirty when,
in reality, it was just stale.

The issue was exposed by python setuptools which hardlinks files into another
directory when building a distribution.

clone: clone from a repository with relative alternates

Cloning from a local repository blindly copies or hardlinks all the files
under objects/ hierarchy. This results in two issues:

 - If the repository cloned has an "objects/info/alternates" file, and the
   command line of clone specifies --reference, the ones specified on the
   command line get overwritten by the copy from the original repository.

 - An entry in a "objects/info/alternates" file can specify the object
   stores it borrows objects from as a path relative to the "objects/"
   directory. When cloning a repository with such an alternates file, if
   the new repository is not sitting next to the original repository, such
   relative paths needs to be adjusted so that they can be used in the new
   repository.

This updates add_to_alternates_file() to take the path to the alternate
object store, including the "/objects" part at the end (earlier, it was
taking the path to $GIT_DIR and was adding "/objects" itself), as it is
technically possible to specify in objects/info/alternates file the path
of a directory whose name does not end with "/objects".

helping smart-http/stateless-rpc fetch race

A request to fetch from a client over smart HTTP protocol is served in
multiple steps. In the first round, the server side shows the set of refs
it has and their values, and the client picks from them and sends "I want
to fetch the history leading to these commits".

When the server tries to respond to this second request, its refs may have
progressed by a push from elsewhere. By design, we do not allow fetching
objects that are not at the tip of an advertised ref, and the server
rejects such a request. The client needs to try again, which is not ideal
especially for a busy server.

Teach upload-pack (which is the workhorse driven by git-daemon and smart
http server interface) that it is OK for a smart-http client to ask for
commits that are not at the tip of any advertised ref, as long as they are
reachable from advertised refs.

filter-branch: Export variable `workdir' for --commit-filter

           ...
           You can use the _map_ convenience function in this filter,
           and other convenience functions, too...
           ...

However, it turns out that `map' hasn't been usable because it depends
on the variable `workdir', which is not propogated to the environment
of the shell that runs the commit-filter <command> because the
shell is created via a simple-command rather than a compound-command
subshell:

 @SHELL_PATH@ -c "$filter_commit" "git commit-tree" \
                 $(git write-tree) $parentstr < ../message > ../map/$commit ||
                         die "could not write rewritten commit"

One solution is simply to export `workdir'. However, it seems rather
heavy-handed to export `workdir' to the environments of all commands,
so instead this commit exports `workdir' for only the duration of the
shell command in question:

 workdir=$workdir @SHELL_PATH@ -c "$filter_commit" "git commit-tree" \
                 $(git write-tree) $parentstr < ../message > ../map/$commit ||

fast-export: quote paths in output

Many pathnames in a fast-import stream need to be quoted. In
particular:

  1. Pathnames at the end of an "M" or "D" line need quoting
     if they contain a LF or start with double-quote.

  2. Pathnames on a "C" or "R" line need quoting as above,
     but also if they contain spaces.

For (1), we weren't quoting at all. For (2), we put
double-quotes around the paths to handle spaces, but ignored
the possibility that they would need further quoting.

This patch checks whether each pathname needs c-style
quoting, and uses it. This is slightly overkill for (1),
which doesn't actually need to quote many characters that
vanilla c-style quoting does. However, it shouldn't hurt, as
any implementation needs to be ready to handle quoted
strings anyway.

In addition to adding a test, we have to tweak a test which
blindly assumed that case (2) would always use
double-quotes, whether it needed to or not.

notice error exit from pager

If the pager fails to run, git produces no output, e.g.:

 $ GIT_PAGER=not-a-command git log

The error reporting fails for two reasons:

 (1) start_command: There is a mechanism that detects errors during
     execvp introduced in 2b541bf8 (start_command: detect execvp
     failures early). The child writes one byte to a pipe only if
     execvp fails.  The parent waits for either EOF, when the
     successful execvp automatically closes the pipe (see
     FD_CLOEXEC in fcntl(1)), or it reads a single byte, in which
     case it knows that the execvp failed. This mechanism is
     incompatible with the workaround introduced in 35ce8622
     (pager: Work around window resizing bug in 'less'), which
     waits for input from the parent before the exec. Since both
     the parent and the child are waiting for input from each
     other, that would result in a deadlock. In order to avoid
     that, the mechanism is disabled by closing the child_notifier
     file descriptor.

 (2) finish_command: The parent correctly detects the 127 exit
     status from the child, but the error output goes nowhere,
     since by that time it is already being redirected to the
     child.

No simple solution for (1) comes to mind.

Number (2) can be solved by not sending error output to the pager.
Not redirecting error output to the pager can result in the pager
overwriting error output with standard output, however.

Since there is no reliable way to handle error reporting in the
parent, produce the output in the child instead.

t7400: fix bogus test failure with symlinked trash

One of the tests in t7400 fails if the trash directory has a
symlink anywhere in its path. E.g.:

  $ mkdir /tmp/git-test
  $ mkdir /tmp/git-test/real
  $ ln -s real /tmp/git-test/link

  $ ./t7400-submodule-basic --root=/tmp/git-test/real

  $ ./t7400-submodule-basic --root=/tmp/git-test/link
  ...
  not ok - 41 use superproject as upstream when path is relative and no url is set there

The failing test does:

  git submodule add ../repo relative &&
  ...
  git submodule sync relative &&
  test "$(git config submodule.relative.url)" = "$submodurl/repo"

where $submodurl comes from the $TRASH_DIRECTORY the user
gave us. However, git will resolve symlinks when converting
the relative path into an absolute one, leading them to be
textually different (even though they point to the same
directory).

Fix this by asking pwd to canonicalize the name of the trash
directory for us.

13 years agodoc/fast-import: clarify notemodify command
Dmitry Ivankov [Wed, 13 Jul 2011 17:10:53 +0000 (23:10 +0600)]
doc/fast-import: clarify notemodify command

The "notemodify" fast-import command was introduced in commit a8dd2e7
(fast-import: Add support for importing commit notes, 2009-10-09)
The commit log has slightly different description than the added
documentation. The latter is somewhat confusing. "notemodify" is a
subcommand of "commit" command used to add a note for some commit.
Does this note annotate the commit produced by the "commit" command
or a commit given by it's committish parameter? Which notes tree
does it write notes to?

The exact meaning could be deduced with old description and some
notes machinery knowledge. But let's make it more obvious. This
command is used in a context like "commit refs/notes/test" to
add or rewrite an annotation for a committish parameter. So the
advised way to add notes in a fast-import stream is:
1) import some commits (optional)
2) prepare a "commit" to the notes tree:
2.1) choose notes ref, committer, log message, etc.
2.2) create annotations with "notemodify", where each can refer to
a commit being annotated via a branch name, import mark reference,
sha1 and other expressions specified in the Documentation.
