This allows a remote helper using the 'export' protocol to specify that
it supports signed tags, changing the handing from 'warn-strip' to
'verbatim'.
Signed-off-by: John Keeping <john@keeping.me.uk>
Signed-off-by: Junio C Hamano <gitster@pobox.com>
Currently, attempting to push a signed tag to a remote helper which uses
fast-export results in the remote helper failing because the default
fast-export action for signed tags is "abort". This is not helpful for
users because there is no way to pass additional arguments to
fast-export here, either from the remote helper or from the command
line.
In general, the signature will be invalidated by whatever transformation
a remote helper performs on a tag to push it to a repository in a
different format so the correct behaviour is to strip the tag. Doing
this silently may surprise people, so use "warn-strip" to issue a
warning when a signed tag is encountered.

with another meaning: to add back all files in <paths> that are

The changes v1.7.12.1~2^2~4 (config: warn on inaccessible files,
2012-08-21) and v1.8.1.1~22^2~2 (config: treat user and xdg config
permission problems as errors, 2012-10-13) were intended to prevent
important configuration (think "[transfer] fsckobjects") from being
ignored when the configuration is unintentionally unreadable (for
example with EIO on a flaky filesystem, or with ENOMEM due to a DoS
attack). Usually ~/.gitconfig and ~/.config/git are readable by the
current user, and if they aren't then it would be easy to fix those
permissions, so the damage from adding this check should have been
minimal.
Unfortunately the access() check often trips when git is being run as
a server. A daemon (such as inetd or git-daemon) starts as "root",
creates a listening socket, and then drops privileges, meaning that
when git commands are invoked they cannot access $HOME and die with
fatal: unable to access '/root/.config/git/config': Permission denied
Any patch to fix this would have one of three problems:
1. We annoy sysadmins who need to take an extra step to handle HOME
when dropping privileges (the current behavior, or any other
proposal that they have to opt into).
2. We annoy sysadmins who want to set HOME when dropping privileges,
either by making what they want to do impossible, or making them
set an extra variable or option to accomplish what used to work
(e.g., a patch to git-daemon to set HOME when --user is passed).
3. We loosen the check, so some cases which might be noteworthy are
not caught.
This patch is of type (3).
Treat user and xdg configuration that are inaccessible due to
permissions (EACCES) as though no user configuration was provided at
all.
An alternative method would be to check if $HOME is readable, but that
would not help in cases where the user who dropped privileges had a
globally readable HOME with only .config or .gitconfig being private.
This does not change the behavior when /etc/gitconfig or .git/config
is unreadable (since those are more serious configuration errors),
nor when ~/.gitconfig or ~/.config/git is unreadable due to problems
other than permissions.

complete (remove_trash is set to $TRASH_DIRECTORY).

There is no point in calling a separate function that is only used
in one place. Especially considering that there's no need to call

and __gitcomp_1.
Let's squash the functions together, and traverse only once.
This improves performance. For N number of words:

The functionality we use from compgen is not much, we can do the same
manually, with drastic improvements in speed, especially when dealing
with only a few words.
This patch also has the sideffect that brekage reported by Jeroen Meijer
and SZEDER Gábor gets fixed because we no longer expand the resulting
words.
Here are some numbers filtering N amount of words:
== 1 ==
original: 0.002s
new: 0.000s
== 10 ==
original: 0.002s
new: 0.000s
== 100 ==
original: 0.003s
new: 0.002s
== 1000 ==
original: 0.012s
new: 0.011s
== 10000 ==
original: 0.056s
new: 0.066s
== 100000 ==
original: 2.669s
new: 0.622s
If the results are not narrowed:
== 1 ==
original: 0.002s
new: 0.000s
== 10 ==
original: 0.002s
new: 0.001s
== 100 ==
original: 0.004s
new: 0.004s
== 1000 ==
original: 0.020s
new: 0.015s

original: 0.101s
new: 0.355s
== 100000 ==
original: 2.850s
new: 31.941s
So, unless 'git checkout <tab>' usually gives you more than 10000
results, you'll get an improvement :)
Other possible solutions perform better after 1000 words, but worst if
less than that:
COMPREPLY=($(awk -v cur="$3" -v pre="$2" -v suf="$4"

When setting up a "half-auth" repository in which reads can
be done anonymously but writes require authentication, it is
best if the server can require authentication for both the
ref advertisement and the actual receive-pack POSTs. This
alleviates the need for the admin to set http.receivepack in
the repositories, and means that the client is challenged
for credentials immediately, instead of partway through the
push process (and git clients older than v1.7.11.7 had
trouble handling these challenges).
Since detecting a push during the ref advertisement requires
matching the query string, and this is non-trivial to do in
Apache, we have traditionally punted and instructed users to
just protect "/git-receive-pack$". This patch provides the
mod_rewrite recipe to actually match the ref advertisement,
which is preferred.
While we're at it, let's add the recipe to our test scripts
so that we can be sure that it works, and doesn't get broken
(either by our changes or by changes in Apache).

The "indegree" field in the commit object is only used while sorting
a list of commits in topological order, and wasting memory otherwise.
We would prefer to shrink the size of individual commit objects,
which we may have to hold thousands of in-core. We could eject
"indegree" field out from the commit object and represent it as a
dynamic table based on the decoration infrastructure, but the
decoration is meant for sparse annotation and is not a good match.
Instead, let's try a different approach.
- Assign an integer (commit->index) to each commit we keep in-core
(reuse the space of "indegree" field for it);
- When running the topological sort, allocate an array of integers
in bulk (called "slab"), use the commit->index as an index into
this array, and store the "indegree" information there.
This does _not_ reduce the memory footprint of a commit object, but
the commit->index can be used as the index to dynamically associate
commits with other kinds of information as needed.

line_log_data has held a diff_filespec* since the very early versions
of the code. However, the only place in the code where we actually
need the full filespec is parse_range_arg(); in all other cases, we
are only interested in the path, so there is hardly a reason to store
a filespec. Even worse, it causes a lot of redundant ->spec->path
pointer dereferencing.
And *even* worse, it caused the following bug. If you merge a rename
with a modification to the old filename, like so:
* Merge
| \
| * Modify foo
| |
* | Rename foo->bar
| /
* Create foo
we internally -- in process_ranges_merge_commit() -- scan all parents.
We are mainly looking for one that doesn't have any modifications, so
that we can assign all the blame to it and simplify away the merge.
In doing so, we run the normal machinery on all parents in a loop.
For each parent, we prepare a "working set" line_log_data by making a
copy with line_log_data_copy(), which does *not* make a copy of the
spec.
Now suppose the rename is the first parent. The diff machinery tells
us that the filepair is ('foo', 'bar'). We duly update the path we
are interested in:
rg->spec->path = xstrdup(pair->one->path);
But that 'struct spec' is shared between the output line_log_data and
the original input line_log_data. So we just wrecked the state of
process_ranges_merge_commit(). When we get around to the second
parent, the ranges tell us we are interested in a file 'foo' while the
commits touch 'bar'.
So most of this patch is just s/->spec->path/->path/ and associated
management changes. This implicitly fixes the bug because we removed
the shared parts between input and output of line_log_data_copy(); it
is now safe to overwrite the path in the copy.
There's one only somewhat related change: the comment in
process_all_files() explains the reasoning behind using 'range' there.
That bit of half-correct code had me sidetracked for a while.
