t7406: Fix submodule init config tests
These tests have been broken since they were introduced in commits
ca2cedb (git-submodule: add support for --rebase., 2009-04-24) and
42b4917 (git-submodule: add support for --merge., 2009-06-03).
'git submodule init' expects the submodules to exist in the index.
In this case, the submodules don't exist and therefore looking for
the submodules will always fail. To make matters worse, git submodule
fails visibly to the user by saying:
error: pathspec 'rebasing' did not match any file(s) known to git.
Did you forget to 'git add'?
but doesn't return an error code. This allows the test to fail silently.
Fix it by adding the submodules first.

gitweb: Fix project-specific feature override behavior
This commit fixes a bug in processing project-specific override in
a situation when there is no project, e.g. for the projects list page.
When 'snapshot' feature had project specific config override enabled
by putting
$feature{'snapshot'}{'override'} = 1;
(or equivalent) in $GITWEB_CONFIG, and when viewing toplevel gitweb
page, which means the projects list page (to be more exact this
happens for any project-less action), gitweb would put the following
Perl warnings in error log:
gitweb.cgi: Use of uninitialized value $git_dir in concatenation (.) or string at gitweb.cgi line 2065.
fatal: error processing config file(s)
gitweb.cgi: Use of uninitialized value $git_dir in concatenation (.) or string at gitweb.cgi line 2221.
gitweb.cgi: Use of uninitialized value $git_dir in concatenation (.) or string at gitweb.cgi line 2218.
The problem is in the following fragment of code:
# path to the current git repository
our $git_dir;
$git_dir = "$projectroot/$project" if $project;
# list of supported snapshot formats
our @snapshot_fmts = gitweb_get_feature('snapshot');
@snapshot_fmts = filter_snapshot_fmts(@snapshot_fmts);
For the toplevel gitweb page, which is the list of projects, $project is not
defined, therefore neither is $git_dir. gitweb_get_feature() subroutine
calls git_get_project_config() if project specific override is turned
on... but we don't have project here.
Those errors mentioned above occur in the following fragment of code in
git_get_project_config():
# get config
if (!defined $config_file ||
$config_file ne "$git_dir/config") {
%config = git_parse_project_config('gitweb');
$config_file = "$git_dir/config";
}
git_parse_project_config() calls git_cmd() which has '--git-dir='.$git_dir
There are (at least) three possible solutions:
1. Harden gitweb_get_feature() so that it doesn't call
git_get_project_config() if $project (and therefore $git_dir) is not
defined; there is no project for project specific config.
2. Harden git_get_project_config() like you did in your fix, returning early
if $git_dir is not defined.
3. Harden git_cmd() so that it doesn't add "--git-dir=$git_dir" if $git_dir
is not defined, and change git_get_project_config() so that it doesn't
even try to access $git_dir if it is not defined.
This commit implements both 1.) and 2.), i.e. gitweb_get_feature() doesn't
call project-specific override if $git_dir is not defined (if there is no
project), and git_get_project_config() returns early if $git_dir is not
defined.
Add a test for this bug to t/t9500-gitweb-standalone-no-errors.sh test.

bisect: error out when passing bad path parameters
As reported by Mark Lodato, "git bisect", when it was started with
path parameters that match no commit was kind of working without
taking account of path parameters and was reporting something like:
Bisecting: -1 revisions left to test after this (roughly 0 steps)
It is more correct and safer to just error out in this case, before
displaying the revisions left, so this patch does just that.
Note that this bug is very old, it exists at least since v1.5.5.
And it is possible to detect that case earlier in the bisect
algorithm, but it is not clear that it would be an improvement to
error out earlier, on the contrary it may change the behavior of
"git rev-list --bisect-all" for example, which is currently correct.

tests: Fix race condition in t7006-pager
Pagers that do not consume their input are dangerous: for example,
$ GIT_PAGER=: git log
$ echo $?
141
$
The only reason these tests were able to work before was that
'git log' would write to the pipe (and not fill it) before the
pager had time to terminate and close the pipe.
Fix it by using a program that consumes its input, namely wc (as
suggested by Johannes).

sha1_file: be paranoid when creating loose objects
We don't want the data being deflated and stored into loose objects
to be different from what we expect. While the deflated data is
protected by a CRC which is good enough for safe data retrieval
operations, we still want to be doubly sure that the source data used
at object creation time is still what we expected once that data has
been deflated and its CRC32 computed.
The most plausible data corruption may occur if the source file is
modified while Git is deflating and writing it out in a loose object.
Or Git itself could have a bug causing memory corruption. Or even bad
RAM could cause trouble. So it is best to make sure everything is
coherent and checksum protected from beginning to end.
To do so we compute the SHA1 of the data being deflated _after_ the
deflate operation has consumed that data, and make sure it matches
with the expected SHA1. This way we can rely on the CRC32 checked by
the inflate operation to provide a good indication that the data is still
coherent with its SHA1 hash. One pathological case we ignore is when
the data is modified before (or during) deflate call, but changed back
before it is hashed.
There is some overhead of course. Using 'git add' on a set of large files:
Before:
real 0m25.210s
user 0m23.783s
sys 0m1.408s
After:
real 0m26.537s
user 0m25.175s
sys 0m1.358s
The overhead is around 5% for full data coherency guarantee.

the data out in small chunks reusing the same memory instead.

t7006-pager: if stdout is not a terminal, make a new one
Testing pagination requires (fake or real) access to a terminal so we
can see whether the pagination automatically kicks in, which makes it
hard to get good coverage when running tests without --verbose. There
are a number of ways to work around that:
- Replace all isatty calls with calls to a custom xisatty wrapper
that usually checks for a terminal but can be overridden for tests.
This would be workable, but it would require implementing xisatty
separately in three languages (C, shell, and perl) and making sure
that any code that is to be tested always uses the wrapper.
- Redirect stdout to /dev/tty. This would be problematic because
there might be no terminal available, and even if a terminal is
available, it might not be appropriate to spew output to it.
- Create a new pseudo-terminal on the fly and capture its output.
This patch implements the third approach.
The new test-terminal.perl helper uses IO::Pty from Expect.pm to create
a terminal and executes the program specified by its arguments with
that terminal as stdout. If the IO::Pty module is missing or not
working on a system, the test script will maintain its old behavior
(skipping most of its tests unless GIT_TEST_OPTS includes --verbose).

cherry_pick_list: quit early if one side is empty
The --cherry-pick logic starts by counting the commits on each side,
so that it can filter away commits on the bigger one. However, so
far it missed an opportunity for optimization: it doesn't need to do
any work if either side is empty.
This in particular helps the common use-case 'git rebase -i HEAD~$n':
it internally uses --cherry-pick, but since HEAD~$n is a direct

tests: Add tests for automatic use of pager
Git’s automatic pagination support has some subtleties. Add some
tests to make sure we don’t break:
- when git will use a pager by default;
- the effect of the --paginate and --no-pager options;
- the effect of pagination on use of color;
- how the choice of pager is configured.
This does not yet test:
- use of pager by scripted commands (git svn and git am);
- effect of the pager.* configuration variables;
- setting of the LESS variable.
Some features involve checking whether stdout is a terminal, so many
of these tests are skipped unless output is passed through to the
terminal (i.e., unless $GIT_TEST_OPTS includes --verbose).
The immediate purpose for these tests was to avoid making things worse
after the breakage from my jn/editor-pager series (see commit 376f39,
2009-11-20). Thanks to Sebastian Celis <sebastian@sebastiancelis.com>

utf8.c: speculatively assume utf-8 in strbuf_add_wrapped_text()
is_utf8() works by calling utf8_width() for each character at the
supplied location. In strbuf_add_wrapped_text(), we do that anyway
while wrapping the lines. So instead of checking the encoding
beforehand, optimistically assume that it's utf-8 and wrap along
until an invalid character is hit, and when that happens start over.
This pays off if the text consists only of valid utf-8 characters.
The following command was run against the Linux kernel repo with
git 1.7.0:
$ time git log --format='%b' v2.6.32 >/dev/null
real 0m2.679s
user 0m2.580s
sys 0m0.100s
$ time git log --format='%w(60,4,8)%b' >/dev/null

$ time git log --format='%w(60,4,8)%b' >/dev/null
real 0m3.741s

docs: don't talk about $GIT_DIR/refs/ everywhere
It is misleading to say that we pull refs from $GIT_DIR/refs/*, because we
may also consult the packed refs mechanism. These days we tend to treat
the "refs hierarchy" as more of an abstract namespace that happens to be
represented as $GIT_DIR/refs. At best, this is a minor inaccuracy, but at
worst it can confuse users who then look in $GIT_DIR/refs and find that it
is missing some of the refs they expected to see.
This patch drops most uses of "$GIT_DIR/refs/*", changing them into just
"refs/*", under the assumption that users can handle the concept of an
abstract refs namespace. There are a few things to note:
- most cases just dropped the $GIT_DIR/ portion. But for cases where
that left _just_ the word "refs", I changed it to "refs/" to help
indicate that it was a hierarchy. I didn't do the same for longer
paths (e.g., "refs/heads" remained, instead of becoming
"refs/heads/").
- in some cases, no change was made, as the text was explicitly about
unpacked refs (e.g., the discussion in git-pack-refs).
- In some cases it made sense instead to note the existence of packed
refs (e.g., in check-ref-format and rev-parse).

This let diff_delta() abort early if it is going to bust the given
size limit. Also, only objects larger than 20 bytes are considered

fast-import: make default pack size unlimited
Now that fast-import is creating packs with index version 2, there is
no point limiting the pack size by default. A pack split will still
happen if off_t is not sufficiently large to hold large offsets.
While updating the doc, let's remove the "packfiles fit on CDs"
suggestion. Pack files created by fast-import are still suboptimal and
a 'git repack -a -f -d' or even 'git gc --aggressive' would be a pretty
good idea before considering storage on CDs.

transport: add got_remote_refs flag
transport_get_remote_refs() in tranport.c checks transport->remote_refs
to determine whether transport->get_refs_list() should be invoked. The
logic is "if it is NULL, we haven't run ls-remote to find out yet".
However, transport->remote_refs could still be NULL while cloning from
an empty repository. This causes get_refs_list() to be run unnecessarily.
Introduce a flag, transport->got_remote_refs, to more explicitly record
if we have run transport->get_refs_list() already.

dwim_ref: fix dangling symref warning
If we encounter a symref that is dangling, in most cases we will warn
about it. The one exception is a dangling HEAD, as that indicates a
branch yet to be born.
However, the check in dwim_ref was not quite right. If we were fed
something like "HEAD^0" we would try to resolve "HEAD", see that it is
dangling, and then check whether the _original_ string we got was
"HEAD" (which it wasn't in this case). And that makes no sense; the
dangling thing we found was not "HEAD^0" but rather "HEAD".
Fixing this squelches a scary warning from "submodule summary HEAD" (and
consequently "git status" with status.submodulesummary set) in an empty
repo, as the submodule script calls "git rev-parse -q --verify HEAD^0".

stash pop: remove 'apply' options during 'drop' invocation
The 'git stash pop' option parsing used to remove the first argument
in --index mode. At the time this was implemented, this first
argument was always --index. However, since the invention of the -q
option in fcdd0e9 (stash: teach quiet option, 2009-06-17) you can
cause an internal invocation of
git stash drop --index
by running
git stash pop -q --index
which then of course fails because drop doesn't know --index.
To handle this, instead let 'git stash apply' decide what the future
argument to 'drop' should be.
Warning: this means that 'git stash apply' must parse all options that
'drop' can take, and deal with them in the same way. This is
currently true for its only option -q.

am: Fix launching of pager
The pagination functionality in git am has some problems:
- It does not check if stdout is a tty, so it always paginates.
- If $GIT_PAGER uses any environment variables, they are being
ignored, since it does not run $GIT_PAGER through eval.
- If $GIT_PAGER is set to the empty string, instead of passing
output through to stdout, it tries to run $dotest/patch.
Fix them. While at it, move the definition of git_pager() to
git-sh-setup so authors of other commands are not tempted to
reimplement it with the same mistakes.

git svn: Fix launching of pager
In commit dec543e (am -i, git-svn: use "git var GIT_PAGER"), I tried
to teach git svn to defer to git var on what pager to use. In the
process, I introduced two bugs:
- The value set for $pager in config_pager has local scope, so
run_pager never sees it;
- git var cannot tell whether git svn’s output is going to a
terminal, so the value chosen for $pager does not reflect that
information.

Make 'git var GIT_PAGER' always print the configured pager
Scripted commands that want to use git’s configured pager know better
than ‘git var’ does whether stdout is going to be a tty at the
appropriate time. Checking isatty(1) as git_pager() does now won’t
cut it, since the output of git var itself is almost never a terminal.
The symptom is that when used by humans, ‘git var GIT_PAGER’ behaves
as it should, but when used by scripts, it always returns ‘cat’!
So avoid tricks with isatty() and just always print the configured
pager.
This does not fix the callers to check isatty(1) themselves yet.
Nevertheless, this patch alone is enough to fix 'am --interactive'.
Thanks to Sebastian Celis for the report and Jeff King for the
analysis.
