Jeff King [Thu, 21 Oct 2010 14:45:44 +0000 (10:45 -0400)]
config: treat non-existent config files as empty

The git_config() function signals error by returning -1 in
two instances:

  1. An actual error occurs in opening a config file (parse
     errors cause an immediate die).

  2. Of the three possible config files, none was found.

However, this second case is often not an error at all; it
simply means that the user has no configuration (they are
outside a repo, and they have no ~/.gitconfig file). This
can lead to confusing errors, such as when the bash
completion calls "git config --list" outside of a repo. If
the user has a ~/.gitconfig, the command completes
succesfully; if they do not, it complains to stderr.

This patch allows callers of git_config to distinguish
between the two cases. Error is signaled by -1, and
otherwise the return value is the number of files parsed.
This means that the traditional "git_config(...) < 0" check
for error should work, but callers who want to know whether
we parsed any files or not can still do so.

Even worse, the outcome depends on whether stdout was already a

 - use the test_terminal script even when running with "-v".

 - skip tests that require a terminal when the test_terminal
   script is unusable because IO::Pty is not installed.

 - write the "need to declare TTY prerequisite" message to fd 4,

mailmap: fix use of freed memory

On an x86_64 system (F13-based), I ran these commands in an empty directory:

    git init
    printf '%s\n' \
      '<jdoe@example.com> <jdoe@example.COM>' \
      'John <jdoe@example.com>' > .mailmap
    git shortlog < /dev/null

Here's the result:

    (reading log message from standard input)
    *** glibc detected *** git: free(): invalid pointer: 0x0000000000f53730 ***
    ======= Backtrace: =========
    /lib64/libc.so.6[0x31ba875676]
    git[0x48c2a5]
    git[0x4b9858]
    ...
    zsh: abort (core dumped)  git shortlog

What happened?

Some .mailmap entry is of the <email1> <email2> form,
while a subsequent one looks like "User Name <Email2>,
and the two email addresses on the right are not identical
but are "equal" when using a case-insensitive comparator.

Then, when add_mapping is processing the latter line, new_email is NULL
and we free me->email, yet do not replace it with a new strdup'd string.
Thus, when later we attempt to use the buffer behind that ->email pointer,
we reference freed memory.

The solution is to free ->email and ->name only if we're about to replace them.

v1.7.3-rc0~75^2 (Teach fast-import to import subtrees named by tree id,

Extend this behaviour by allowing the root to be referenced as the
empty path, "".

For a command (like filter-branch --subdirectory-filter) that wants
to commit a lot of trees that already exist in the object db, writing
undeltified objects as loose files only to repack them later can
involve a significant amount of overhead.
(23% slow-down observed on Linux 2.6.35, worse on Mac OS X 10.6)

Fortunately we have fast-import (which is one of the only git commands
that will write to a pack directly) but there is not an advertised way
to tell fast-import to commit a given tree without unpacking it.

This patch changes that, by allowing

M 040000 <tree id> ""

as a filemodify line in a commit to reset to a particular tree without
any need to parse it.  For example,

M 040000 4b825dc642cb6eb9a060e54bf8d69288fbee4904 ""

gitweb: Fix bug in evaluate_path_info

There was bug in parsing "project/:/file" and "project/:/" path_info
URLs, with implicit HEAD as 'hash_base'.

For such URLs the refname is empty, and before this fix regexp for
parsing path_info fragment assumed that it is always non-empty.

Refname cannot contain ':', as per 'git check-ref-format'.
