42639d2317 submodules: add the lib-submodule-update.sh test library
Add this test library to simplify covering all combinations of submodule
update scenarios without having to add those to a test of each work tree
manipulating command over and over again.

The functions test_submodule_switch() and test_submodule_forced_switch()
are intended to be called from a test script with a single argument. This
argument is either a work tree manipulating command (including any command
line options) or a function (when more than a single git command is needed
to switch work trees from the current HEAD to another commit). This
command (or function) is passed a target branch as argument. The two new
functions check that each submodule transition is handled as expected,
which currently means that submodule work trees are not affected until
"git submodule update" is called. The "forced" variant is for commands
using their '-f' or '--hard' option and expects them to overwrite local
modifications as a result. Each of these two functions contains 14
tests_expect_* calls.

Calling one of these test functions the first time creates a repository
named "submodule_update_repo". At first it contains two files, then a
single submodule is added in another commit followed by commits covering
all relevant submodule modifications. This repository is newly cloned into
the "submodule_update" for each test_expect_* to avoid interference
between different parts of the test functions (some to-be-tested commands
also manipulate refs along with the work tree, e.g. "git reset").

Follow-up commits will then call these two test functions for all work
tree manipulating commands (with a combination of all their options
relevant to what they do with the work tree) making sure they work as
expected. Later this test library will be extended to cover merges
resulting in conflicts too. Also it is intended to be easily extendable
for the recursive update functionality, where even more combinations of
submodule modifications have to be tested for.

This version documents two bugs in current Git with expected failures:

*) When a submodule is replaced with a tracked file of the same name the
   submodule work tree including any local modifications (and even the
   whole history if it uses a .git directory instead of a gitfile!) is
   silently removed.

*) Forced work tree updates happily manipulate files in the directory of a
   submodule that has just been removed in the superproject (but is of
   course still present in the work tree due to the way submodules are
   currently handled). This becomes dangerous when files in the submodule
   directory are overwritten by files from the new superproject commit, as
   any modifications to the submodule files will be lost) and is expected
   to also destroy history in the - admittedly unlikely case - the new
   commit adds a file named ".git" to the submodule directory.

00f6991d4b t/Makefile: always test all lint targets when running tests
Only the two targets "test-lint-duplicates" and "test-lint-executable" are
currently executed when running the test target. This was done on purpose
when the TEST_LINT variable was added in 81127d74 to avoid twisted shell
scripting by developers only to avoid false positives that might result
from the rather simple minded tests, e.g. test-lint-shell-syntax. But it
looks like it might be better to include all lint tests to help developers
to detect non portable shell constructs before the patch is sent to the
list and reviewed there.

Change the TEST_LINT variable to run all lint test unless the TEST_LINT
variable is overridden. If we hit false positives more often than helping
developers to avoid non-portable code (or add less accurate or slow tests
later) we could still fall back to exclude them like 81127d74 proposed.

cd78cea29d t/Makefile: check helper scripts for non-portable shell commands too
Currently only the "t[0-9][0-9][0-9][0-9]-*.sh" scripts are tested for
shell incompatibilities using the check-non-portable-shell.pl script. This
makes it easy to miss non-POSIX constructs added to one of the t/*lib*.sh
helper scripts, as they aren't automatically detected.

Fix that by adding a THELPERS variable containing all shell scripts that
aren't tests and add these to the "test-lint-shell-syntax" target too.

343151dcbd t0027: combinations of core.autocrlf, core.eol and text
Historically there are 3 different parameters controlling how line endings
are handled by Git:
- core.autocrlf
- core.eol
- the "text" attribute in .gitattributes

There are different types of content:
- (1) Files with only LF
- (2) Files with only CRLF
- (3) Files with mixed LF and CRLF
- (4) Files with LF and/or CRLF with CR not followed by LF
- (5) Files which are binary (e.g. have NUL bytes)

Recently the question came up, how files with mixed EOLs are handled by Git
(and libgit2) when they are checked out and core.autocrlf=true.

See
http://git.661346.n2.nabble.com/The-different-EOL-behavior-between-libgit2-based-software-and-official-Git-td7613670.html#a7613801

Add the EXPENSIVE t0027-auto-crlf.sh to test all combination of files
and parameters for both "git add/commit" and "git checkout".

After the renaming we can see easier that we may want more test cases
for 2 types of files:
- files which have mixed LF and CRLF line endings,
- files which have mixed LF and CR line endings.

See commit fd6cce9e, "Add per-repository eol normalization" and
"the new safer autocrlf handling" in convert.c

21711ca4b2 t5000, t5003: simplify commit
Add the whole directory of test files at once using git add instead of
calling git update-index on each of them and use git commit instead of
the plumbing commands write-tree, update-ref and commit-tree to build
the commit.  This simplifies the code considerably.

7b64d42d22 hashmap: add string interning API
Interning short strings with high probability of duplicates can reduce the
memory footprint and speed up comparisons.

Add strintern() and memintern() APIs that use a hashmap to manage the pool
of unique, interned strings.

Note: strintern(getenv()) could be used to sanitize git's use of getenv(),
in case we ever encounter a platform where a call to getenv() invalidates
previous getenv() results (which is allowed by POSIX).

45067fc973 t7300: repair filesystem permissions with test_when_finished
We create a directory that cannot be removed, confirm that
it cannot be removed, and then fix it like:

  chmod 0 foo &&
  test_must_fail git clean -d -f &&
  chmod 755 foo

If the middle step fails but leaves the directory (e.g., the
bug is that clean does not notice the failure), this
pollutes the test repo with an unremovable directory. Not
only does this cause further tests to fail, but it means
that "rm -rf" fails on the whole trash directory, and the
user has to intervene manually to even re-run the test script.

We can bump the "chmod 755" recovery to a test_when_finished
block to be sure that it always runs.

79bc4ef368 filter-branch: eliminate duplicate mapped parents
When multiple parents of a merge commit get mapped to the same
commit, filter-branch used to pass all instances of the parent
commit to the parent and commit filters and to "git commit-tree" or
"git_commit_non_empty_tree".

This can often happen when extracting a small project from a large
repository; merges can join history with no commits on any branch
which affect the paths being retained.  Once the intermediate
commits have been filtered out, all the immediate parents of the
merge commit can end up being mapped to the same commit - either the
original merge-base or an ancestor of it.

"git commit-tree" would display an error but write the commit with
the normalized parents in any case.  "git_commit_non_empty_tree"
would fail to notice that the commit being made was in fact a
non-merge commit and would retain it even if a further pass with
"--prune-empty" would discard the commit as empty.

Ensure that duplicate parents are pruned before the parent filter to
make "--prune-empty" idempotent, removing all empty non-merge
commits in a singe pass.

ba311807f8 git-merge-file: do not add LF at EOF while applying unrelated change
If 'current-file' does not contain LF at EOF, and change between
'base-file' and 'other-file' does not change any line close to EOF, the
3-way merge should not add LF to EOF.  This is what 'diff3 -m' does, and
seems to be a reasonable expectation.

The change which introduced the behavior is cd1d61c44f. It always calls
function xdl_recs_copy() for sides with add_nl == 1. In fact, it looks
like the only case when this is needed is when 2 files are being
union-merged, and they do not have LF at EOF (strictly speaking, the
first of them).

Add tests:
* "merge without conflict (missing LF at EOF, away from change in the
other file)" and "merge does not add LF away of change", to demonstrate
the changed behavior.
* "conflict at EOF without LF resolved by --union", to verify that the
union-merge at the end inerts newline between versions.
* some more tests which I felt like not covering the functionality well

6d49de414f t6023-merge-file.sh: fix and mark as broken invalid tests
Tests "merge without conflict (missing LF at EOF" and "merge result
added missing LF" are meaningless - the first one is identical to
"merge without conflict" and the second compares results of those
identical tests, which are always same.

This has been so since their addition in ba1f5f3537. Probably "new4.txt"
was meant to be used instead of "new2.txt". Unfortunately, the current
merge-file breaks with new4 - conflict is reported. They also fail at
that revision if fixed.

Fix the file reference to "new4.txt" and mark the tests as failing -
they look like legitimate expectations, just not satisfied at time
being.
