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).

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).

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>

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.

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.
Fix them.

The --paginate option is meant to negate the effect of an explicit or
implicit pager.<cmd> = false setting. Thus it turns the pager on if
output is going to a terminal rather than unconditionally.

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.

When 921177f (Documentation: improve "add", "pull" and "format-patch"
examples, 2008-05-07) converted this from enumeration header to displayed

In displayed text, backslash is shown verbatim, while in enumeration
header, we need to double it.
We have a similar construct in git-rm.txt documentation, and need to be
careful when somebody wants to update it to match the style of the "git

The code to guess an output archive's format consumed any --format
options and built a new one. Jonathan noticed that it does so in an
unsafe way, risking to overflow the static buffer fmt_opt.
Change the code to keep the existing --format options intact and to only
add a new one if a format could be guessed based on the output file name.
The new option is added as the first one, allowing the existing ones to
overrule it, i.e. explicit --format options given on the command line win
over format guesses, as before.
To simplify the code further, format_from_name() is changed to return the
full --format option, thus no potentially dangerous sprintf() calls are
needed any more.

This function did not work on strings that were not NUL-terminated. It
reads through a length-bounded string, searching for characters in need of
quoting. After we find one, we output the quoted character, then advance
our pointer to find the next one. However, we never decremented the
length, meaning we ended up looking at whatever random junk was stored
after the string.
This bug was not found by the existing tests because most code paths feed
a NUL-terminated string. The notable exception is a directory name being
fed by ls-tree.

the max-load-limit codepath produces results cleanly, when gitweb is

method.
The code to check for load returns 0 if it doesn't know how to find
load. It also checks to see if the current load is higher than the
max load. So to force the script to quit early by setting the maxload
variable negative which should work for systems where we can detect
load (which should be a positive number) and systems where we can't
(where detected load is 0)
