bisect: fix quoting TRIED revs when "bad" commit is also "skip"ped

When the "bad" commit was also "skip"ped and when more than one
commit was skipped, the "filter_skipped" function would have
printed something like:

    bisect_rev=<hash1>|<hash2>

(where <hash1> and <hash2> are hexadecimal sha1 hashes)

and this would have been evaled later as piping "bisect_rev=<hash1>"
into "<hash2>", which would have failed.

So this patch makes the "filter_skipped" function properly quote
what it outputs, so that it will print something like:

bisect_rev='<hash1>|<hash2>'

which will be properly evaled later.  The caller was not stopping
properly because the scriptlet this function returned to be evaled
was not strung together with && and because of this, an error in
an earlier part of the output was simply ignored.

A test case is added to the test suite.

And while at it, we also initialize the VARS, FOUND and TRIED
variables, so that we protect ourselves from environment variables

In a repository created with git older than f49fb35 (git-init-db: create

created as needed inside directories init-db creates, and back then,
packfiles were recent invention.

After the said commit, new codepaths started relying on the presense of
objects/pack/ directory in the repository.  This was exacerbated with
8b4eb6b (Do not perform cross-directory renames when creating packs,
2008-09-22) that moved the location temporary pack files are created from
objects/ directory to objects/pack/ directory, because moving temporary to
the final location was done carefully with lazy leading directory creation.

Many packfile related operations in such an old repository can fail
mysteriously because of this.

This commit introduces two helper functions to make things work better.

 - odb_mkstemp() is a specialized version of mkstemp() to refactor the
   code and teach it to create leading directories as needed;

 - odb_pack_keep() refactors the code to create a ".keep" file while

Make repack less likely to corrupt repository

Some platforms refuse to rename a file that is open.  When repacking an
already packed repository without adding any new object, the resulting
pack will contain the same set of objects as an existing pack, and on such
platforms, a newly created packfile cannot replace the existing one.

The logic detected this issue but did not try hard enough to recover from
it.  Especially because the files that needs renaming come in pairs, there
potentially are different failure modes that one can be renamed but the
others cannot.  Asking manual recovery to end users were error prone.

This patch tries to make it more robust by first making sure all the
existing files that need to be renamed have been renamed before
continuing, and attempts to roll back if some failed to rename.

instead of normalize_absolute_path() because the latter is about to be
removed.

The test cases in t0060 are adjusted in two regards:

- normalize_path_copy() more often leaves a trailing slash in the result.
  This has no negative side effects because the new user of this function,
  longest_ancester_length(), already accounts for this behavior.

- The function can fail.

The tests uncover a flaw in normalize_path_copy(): If there are
sufficiently many '..' path components so that the root is reached, such as
in "/d1/s1/../../d2", then the leading slash was lost. This manifested
itself that (assuming there is a repository at /tmp/foo)

  $ git add /d1/../tmp/foo/some-file

reported 'pathspec is outside repository'. This is now fixed.

Fix GIT_CEILING_DIRECTORIES on Windows

paths to start with a slash, while on Windows they can start with a drive

which can handle Windows-style paths just fine.

Secondly, the portability macro PATH_SEP is used instead of expecting
colons to be used as path list delimiter.

  WARNING: Ref 'refs/heads/branch' is unchanged
  fatal: This operation must be run in a work tree

Note that this fatal error message doesn't prevent git filter-branch from
exiting successfully. (Why doesn't git filter-branch actually exit with an
error when a shell command fails? I'm not sure why it was designed this
way.)

This error message is caused by the following section of code at the end of
git-filter-branch.sh:

  if [ "$(is_bare_repository)" = false ]; then
          unset GIT_DIR GIT_WORK_TREE GIT_INDEX_FILE
          test -z "$ORIG_GIT_DIR" || {
                  GIT_DIR="$ORIG_GIT_DIR" && export GIT_DIR
          }
          ... elided ...
          git read-tree -u -m HEAD
  fi

The problem is the call to $(is_bare_repository), which is made before
GIT_DIR and GIT_WORK_TREE are restored.  This call always returns "false",
even when we're running in a bare repository.  But this means that we will
attempt to call 'git read-tree' even in a bare repository, which will fail
and print an error.

This patch modifies git-filter-branch.sh to restore the original
environment variables before trying to call is_bare_repository.

The parameter n of unpack_callback() can have a value of up to
MAX_UNPACK_TREES.  The check at the top of unpack_trees() (its only
(indirect) caller) makes sure it cannot exceed this limit.

unpack_callback() passes it and the array src to unpack_nondirectories(),

o->merge can be 0 or 1, so unpack_nondirectories() potentially accesses

15 years agogit: use run_command() to execute dashed externals
Jeff King [Wed, 28 Jan 2009 07:38:14 +0000 (02:38 -0500)]
git: use run_command() to execute dashed externals

We used to simply try calling execvp(); if it succeeded, then we were done
and the new program was running. If it didn't, then we knew that it wasn't
a valid command.

Unfortunately, this interacted badly with the new pager handling. Now that
git remains the parent process and the pager is spawned, git has to hang
around until the pager is finished. We install an atexit handler to do
this, but that handler never gets called if we successfully run execvp.

You could see this behavior by running any dashed external using a pager
(e.g., "git -p stash list"). The command finishes running, but the pager
is still going. In the case of less, it then gets an error reading from
the terminal and exits, potentially leaving the terminal in a broken state
(and not showing the output).

This patch just uses run_command() to try running the dashed external. The
parent git process then waits for the external process to complete and
then handles the pager cleanup as it would for an internal command.

15 years agorun_command(): handle missing command errors more gracefully
Jeff King [Wed, 28 Jan 2009 07:35:33 +0000 (02:35 -0500)]
run_command(): handle missing command errors more gracefully

When run_command() was asked to run a non-existant command, its behavior
varied depending on the platform:

  - on POSIX systems, we would fork, and then after the execvp call
    failed, we could call die(), which prints a message to stderr and
    exits with code 128.

  - on Windows, we do a PATH lookup, realize the program isn't there, and
    then return ERR_RUN_COMMAND_FORK

The goal of this patch is to make it clear to callers that the specific
error was a missing command. To do this, we will return the error code
ERR_RUN_COMMAND_EXEC, which is already defined in run-command.h, checked
for in several places, but never actually gets set.

The new behavior is:

  - on POSIX systems, we exit the forked process with code 127 (the same
    as the shell uses to report missing commands). The parent process
    recognizes this code and returns an EXEC error. The stderr message is
    silenced, since the caller may be speculatively trying to run a
    command. Instead, we use trace_printf so that somebody interested in
    debugging can see the error that occured.

  - on Windows, we check errno, which is already set correctly by
    mingw_spawnvpe, and report an EXEC error instead of a FORK error

Thus it is safe to speculatively run a command:

  int r = run_command_v_opt(argv, 0);
  if (r == -ERR_RUN_COMMAND_EXEC)
  /* oops, it wasn't found; try something else */
  else
  /* we failed for some other reason, error is in r */
