travis: build with patched libcurl
Ubuntu trusty has a bug in curl when using NTLM credentials in a proxy,
dereferencing a null pointer and causing segmentation faults. Use a
custom-patched version of libcurl that avoids this issue.

config_file: refuse modifying included variables
Modifying variables pulled in by an included file currently succeeds,
but it doesn't actually do what one would expect, as refreshing the
configuration will cause the values to reappear. As we are currently not
really able to support this use case, we will instead just return an
error for deleting and setting variables which were included via an
include.

config_file: pass reader directly to callbacks
Previously, the callbacks passed to `config_parse` got the reader via a
pointer to a pointer. This allowed the callbacks to update the callers
`reader` variable when the array holding it has been reallocated. As the
array is no longer present, we can simply the code by making the reader
a simple pointer.

config_file: refactor include handling
Current code for configuration files uses the `reader` structure to
parse configuration files and store additional metadata like the file's
path and checksum. These structures are stored within an array in the
backend itself, which causes multiple problems.
First, it does not make sense to keep around the file's contents with
the backend itself. While this data is usually free'd before being added
to the backend, this brings along somewhat intricate lifecycle problems.
A better solution would be to store only the file paths as well as the
checksum of the currently parsed content only.
The second problem is that the `reader` structures are stored inside an
array. When re-parsing configuration files due to changed contents, we
may cause this array to be reallocated, requiring us to update pointers
hold by callers. Furthermore, we do not keep track of includes which
are already associated to a reader inside of this array. This causes us
to add readers multiple times to the backend, e.g. in the scenario of
refreshing configurations.
This commit fixes these shortcomings. We introduce a split between the
parsing data and the configuration file's metadata. The `reader` will
now only hold the file's contents and the parser state and the new
`config_file` structure holds the file's path and checksum. Furthermore,
the new structure is a recursive structure in that it will also hold
references to the files it directly includes. The diskfile is changed to
only store the top-level configuration file.
These changes allow us further refactorings and greatly simplify
understanding the code.

config_file: move reader into `config_read` only
Right now, we have multiple call sites which initialize a `reader`
structure. As the structure is only actually used inside of
`config_read`, we can instead just move the reader inside of the
`config_read` function. Instead, we can just pass in the configuration
file into `config_read`, which eases code readability.

config_file: refresh all files if includes were modified
Currently, we only re-parse the top-level configuration file when it has
changed itself. This can cause problems when an include is changed, as
we were not updating all values correctly.
Instead of conditionally reparsing only refreshed files, the logic
becomes much clearer and easier to follow if we always re-parse the
top-level configuration file when either the file itself or one of its
included configuration files has changed on disk. This commit implements
this logic.
Note that this might impact performance in some cases, as we need to
re-read all configuration files whenever any of the included files
changed. It could increase performance to just re-parse include files
which have actually changed, but this would compromise maintainability
of the code without much gain. The only case where we will gain anything
is when we actually use includes and when only these includes are
updated, which will probably be quite an unusual scenario to actually be
worthwhile to optimize.

signature: don't leave a dangling pointer to the strings on parse failure
If the signature is invalid but we detect that after allocating the strings, we
free them. We however leave that pointer dangling in the structure the caller
gave us, which can lead to double-free.
Set these pointers to `NULL` after freeing their memory to avoid this.

tests: config: fix missing declaration causing error
On systems where we pull in our distributed version of the regex
library, all tests in config::readonly fail. This error is actually
quite interesting: the test suite is unable to find the declaration of
`git_path_exists` and assumes it has a signature of `int
git_path_exists(const char *)`. But actually, it has a `bool` return
value. Due to this confusion, some wrong conversion is done by the
compiler and the `cl_assert(!git_path_exists("file"))` checks
erroneously fail, even when the function does in fact return the correct
value.
The error is actually introduced by 56893bb9a (cmake: consistently use
TARGET_INCLUDE_DIRECTORIES if available, 2017-06-28), unfortunately
introduced by myself. Due to the delayed addition of include
directories, we will now find the "config.h" header inside of the
"deps/regex" directory instead of inside the "src/" directory, where it
should be. As such, we are missing definitions for the
`git_config_file__ondisk` and `git_path_exists` symbols.
The correct fix here would be to fix the order in which include search
directories are added. But due to the current restructuring of
CMakeBuild.txt, I'm refraining from doing so and delay the proper fix a
bit. Instead, we paper over the issue by explicitly including "path.h"
to fix its prototype. This ignores the issue that
`git_config_file__ondisk` is undeclared, as its signature is correctly
identified by the compiler.

diff: implement function to calculate patch ID
The upstream git project provides the ability to calculate a so-called
patch ID. Quoting from git-patch-id(1):
A "patch ID" is nothing but a sum of SHA-1 of the file diffs
associated with a patch, with whitespace and line numbers ignored."
Patch IDs can be used to identify two patches which are probably the
same thing, e.g. when a patch has been cherry-picked to another branch.
This commit implements a new function `git_diff_patchid`, which gets a
patch and derives an OID from the diff. Note the different terminology
here: a patch in libgit2 are the differences in a single file and a diff
can contain multiple patches for different files. The implementation
matches the upstream implementation and should derive the same OID for
the same diff. In fact, some code has been directly derived from the
upstream implementation.
The upstream implementation has two different modes to calculate patch
IDs, which is the stable and unstable mode. The old way of calculating
the patch IDs was unstable in a sense that a different ordering the
diffs was leading to different results. This oversight was fixed in git
1.9, but as git tries hard to never break existing workflows, the old
and unstable way is still default. The newer and stable way does not
care for ordering of the diff hunks, and in fact it is the mode that
should probably be used today. So right now, we only implement the
stable way of generating the patch ID.

tests: refs::crashes: create sandbox for creating symref
The test `refs::crashes::double_free` operates on our in-source
"testrepo.git" repository without creating a copy first. As the test

to do a pure out-of-tree build with a read-only source tree.

cmake: generate clar.suite in binary directory

generate.py: generate clar cache in binary directory
The source directory should usually not be touched when using

breaking the builds. Fix this by also honoring the output directory for

generate.py: enable overriding path of generated clar.suite

generate.py: disallow generating test suites for multiple paths
Our generate.py script is used to extract and write test suite
declarations into the clar.suite file. As is, the script accepts
multiple directories on the command line and will generate this file for
each of these directories.
The generate.py script will always write the clar.suite file into the
directory which is about to be scanned. This actually breaks
out-of-tree builds with libgit2, as the file will be generated in the
source tree instead of in the build tree. This is noticed especially in
the case where the source tree is mounted read-only, rendering us unable
to build unit tests.
Due to us accepting multiple paths which are to be scanned, it is not
trivial to fix though. The first solution which comes into mind would be
to re-create the directory hierarchy at a given output path or use
unique names for the clar.suite files, but this is rather cumbersome and
magical. The second and cleaner solution would be to fold all
directories into a single clar.suite file, but this would probably break
some use-cases.
Seeing that we do not ever pass multiple directories to generate.py, we
will now simply retire support for this. This allows us to later on
introduce an additional option to specify the path where the clar.suite
file will be generated at, defaulting to "clar.suite" inside of the
scanned directory.

cmake: Permit disabling external http-parser
When attempting to build libgit2 as an isolated static lib, CMake
gleefully attempts to use the system http-parser. This is typically
seen on Linux systems which install header files with every package,
such as Gentoo.
Allow developers to forcibly disable using the system http-parser with
the config switch USE_EXT_HTTP_PARSER. Defaults to ON to maintain
previous behavior.

travis: upgrade container to Ubuntu 14.04
Ubuntu 12.04 (Precise Pangolin) reaches end of life on April 28th, 2017.
As such, we should update our build infrastructure to use the next
available LTS release, which is Ubuntu 14.04 LTS (Trusty Tahr). Note
that Trusty is still considered beta quality on Travis. But considering
we are able to correctly build and test libgit2, this seems to be a
non-issue for us.
Switch over our default distribution to Trusty. As Precise still has
extended support for paying customers, add an additional job which
compiles libgit2 on the old release.

travis: cibuild: set up our own sshd server
Some tests of ours require to be running against an SSH server.
Currently, we simply run against the SSH server provided and started by
Travis itself. As our Linux tests run in a sudo-less environment, we
have no control over its configuration and startup/shutdown procedure.
While this has been no problem until now, it will become a problem as
soon as we migrate over to newer Precise images, as the SSH server does
not have any host keys set up. Luckily, we can simply set up our own
unpriviledged SSH server. This has the benefit of us being able to
modify its configuration even in a sudo-less environment.
This commit sets up the unpriviledged SSH server on port 2222.

not running on the standard port, e.g. when it is running as a user.
Fix the issue by using the URL provided by the environment.

cmake: disable optimization on debug builds
While our debug builds on MSVC platforms already tune the code optimizer
to aid debugging code, all the other platforms still use the default
optimization level. This makes it hard for developers on these platforms
to actually debug code while maintaining his sanity due to optimizations
like inlined code, elided variables etc.
To help this common use case, we can simply follow the MSVC example and
turn off code optimization with "-O0" for debug builds. While it would
be preferable to instead use "-Og" supported by more modern compilers,
we cannot guarantee that this level is available on all supported
platforms.

cmake: set "-D_DEBUG" on non-Windows platforms
In our code base, we have some occasions where we use the "_DEBUG"
preprocessor macro to enable additional code which should not be part of
release builds. While we define this flag on MSVC platforms, it is
guarded by the conditional `WIN32 AND NOT CYGWIN` on other platforms
since 19be3f9e6 (Improve MSVC compiler, linker flags, 2013-02-13). While
this condition can be fulfilled by the MSVC platform, it is never
encountered due to being part of the `ELSE` part of `IF (MSVC)`.
The intention of the conditional was most likely to avoid the
preprocessor macro on Cygwin platforms, but to include it on everthing
else. As such, the correct condition here would be `IF (NOT CYGWIN)`
instead. But digging a bit further, the condition is only ever used in
two places:
1. To skip the test in "core::structinit", which should also work on
Cygwin.
2. In "src/win32/git2.rc", where it is used to set additional file
flags. As this file is included in MSVC builds only, it cannot cause
any harm to set "_DEBUG" on Cygwin here.
As such, we can simply drop the conditional and always set "-D_DEBUG" on
all platforms.

Disambiguate error values: return `GIT_ENOTFOUND` when the item cannot

otherwise not backed by a filesystem), return `-1` when there is a hard
failure.

tests: odb: add tests with multiple backends
Previous to pulling out and extending the fake backend, it was quite
cumbersome to write tests for very specific scenarios regarding
backends. But as we have made it more generic, it has become much easier
to do so. As such, this commit adds multiple tests for scenarios with
multiple backends for the ODB.
The changes also include a test for a very targeted scenario. When one
backend found a matching object via `read_prefix`, but the last backend
returns `GIT_ENOTFOUND` and when object hash verification is turned off,
we fail to reset the error code to `GIT_OK`. This causes us to segfault
later on, when doing a double-free on the returned object.

tests: odb: allow passing fake objects to the fake backend
Right now, the fake backend is quite restrained in the way how it
works: we pass it an OID which it is to return later as well as an error
code we want it to return. While this is sufficient for existing tests,
we can make the fake backend a little bit more generic in order to allow
us testing for additional scenarios.
To do so, we change the backend to not accept an error code and OID
which it is to return for queries, but instead a simple array of OIDs
with their respective blob contents. On each query, the fake backend
simply iterates through this array and returns the first matching
object.

tests: do not reuse OID from backend
In order to make the fake backend more useful, we want to enable it
holding multiple object references. To do so, we need to decouple it
from the single fake OID it currently holds, which we simply move up
into the calling tests.

tests: odb: move fake backend into its own file
The fake backend used by the test suite `odb::backend::nonrefreshing` is
useful to have some low-level tests for the ODB layer. As such, we move
the implementation into its own `backend_helpers` module.

odb_read_prefix: reset error in backends loop
When looking for an object by prefix, we query all the backends so that
we can ensure that there is no ambiguity. We need to reset the `error`
value between backends; otherwise the first backend may find an object
by prefix, but subsequent backends may not. If we do not reset the
`error` value then it will remain at `GIT_ENOTFOUND` and `read_prefix_1`
will fail, despite having actually found an object.

checkout: cope with untracked files in directory deletion
When deleting a directory during checkout, do not simply delete the
directory, since there may be untracked files. Instead, go into
the iterator and examine each file.
In the original code (the code with the faulty assumption), we look to
see if there's an index entry beneath the directory that we want to
remove. Eg, it looks to see if we have a workdir entry foo and an
index entry foo/bar.txt. If this is not the case, then the working
directory must have precious files in that directory. This part is okay.
The part that's not okay is if there is an index entry foo/bar.txt. It
just blows away the whole damned directory.
That's not cool.
Instead, by simply pushing the directory itself onto the stack and
iterating each entry, we will deal with the files one by one - whether
they're in the index (and can be force removed) or not (and are
precious).
The original code was a bad optimization, assuming that we didn't need
to git_iterator_advance_into if there was any index entry in the folder.
That's wrong - we could have optimized this iff all folder entries are
in the index.
Instead, we need to simply dig into the directory and analyze its
entries.

checkout: do not delete directories with untracked entries
If the `GIT_CHECKOUT_FORCE` flag is given to any of the `git_checkout`
invocations, we remove files which were previously staged. But while
doing so, we unfortunately also remove unstaged files in a directory
which contains at least one staged file, resulting in potential data
loss.
This commit adds two tests to verify behavior.

smart_protocol: fix parsing of server ACK responses
Fix ACK parsing in wait_while_ack() internal function. This patch
handles the case where multi_ack_detailed mode sends 'ready' ACKs. The
existing functionality would bail out too early, thus causing the
processing of the ensuing packfile to fail if/when 'ready' ACKs were
sent.

settings: rename `GIT_OPT_ENABLE_SYNCHRONOUS_OBJECT_CREATION`
Initially, the setting has been solely used to enable the use of
`fsync()` when creating objects. Since then, the use has been extended
to also cover references and index files. As the option is not yet part
of any release, we can still correct this by renaming the option to
something more sensible, indicating not only correlation to objects.
This commit renames the option to `GIT_OPT_ENABLE_FSYNC_GITDIR`. We also
move the variable from the object to repository source code.

buffer: use `git_buf_init` with length
The `git_buf_init` function has an optional length parameter, which will
cause the buffer to be initialized and allocated in one step. This can
be used instead of static initialization with `GIT_BUF_INIT` followed by
a `git_buf_grow`. This patch does so for two functions where it is
applicable.

buffer: return errors for `git_buf_init` and `git_buf_attach`
Both the `git_buf_init` and `git_buf_attach` functions may call
`git_buf_grow` in case they were given an allocation length as
parameter. As such, it is possible for these functions to fail when we
run out of memory. While it won't probably be used anytime soon, it does
indeed make sense to also record this fact by returning an error code
from both functions. As they belong to the internal API only, this
change does not break our interface.

buffer: consistently use `ENSURE_SIZE` to grow buffers on-demand
The `ENSURE_SIZE` macro can be used to grow a buffer if its currently
allocated size does not suffice a required target size. While most of
the code already uses this macro, the `git_buf_join` and `git_buf_join3`
functions do not yet use it. Due to the macro first checking whether we
have to grow the buffer at all, this has the benefit of saving a
function call when it is not needed. While this is nice to have, it will
probably not matter at all performance-wise -- instead, this only serves
for consistency across the code.

buffer: fix `ENSURE_SIZE` macro referencing wrong variable
While the `ENSURE_SIZE` macro gets a reference to both the buffer that
is to be resized and a new size, we were not consistently referencing
the passed buffer, but instead a variable `buf`, which is not passed in.
Funnily enough, we never noticed because our buffers seem to always be
named `buf` whenever the macro was being used.
Fix the macro by always using the passed-in buffer. While at it, add
braces around all mentions of passed-in variables as should be done with
macros to avoid subtle errors.

buffer: rely on `GITERR_OOM` set by `git_buf_try_grow`
The function `git_buf_try_grow` consistently calls `giterr_set_oom`
whenever growing the buffer fails due to insufficient memory being
available. So in fact, we do not have to do this ourselves when a call
to any buffer-growing function has failed due to an OOM situation. But
we still do so in two functions, which this patch cleans up.

sha1dc: do not use standard includes
The updated SHA1DC library allows us to use custom includes instead of
using standard includes. Due to requirements with cross-platform, we
provide some custom system includes files like for example the
"stdint.h" file on Win32. Because of this, we want to make sure to avoid
breaking cross-platform compatibility when SHA1DC is enabled.
To use the new mechanism, we can simply define
`SHA1DC_NO_STANDARD_INCLUDES`. Furthermore, we can specify custom
include files via two defines, which we now use to include our
"common.h" header.
