Subject: BF: allow for other section names which start with a string "remote"

by demanding a space after a word remote, and space is explicitly described as
a delimiter in man git-config:

otherwise e.g.

    for remote in self.repo.remotes:

-################
-Whats New in 0.3
-################
-GitPython 0.3 is the first step in creating a hybrid which uses a pure python implementations for all simple git features which can be implemented without significant performance penalties. Everything else is still performed using the git command, which is nicely integrated and easy to use.
-
-Its biggest strength, being the support for all git features through the git command itself, is a weakness as well considering the possibly vast amount of times the git command is being started up. Depending on the actual command being performed, the git repository will be initialized on many of these invocations, causing additional overhead for possibly tiny operations.
-
-Keeping as many major operations in the python world will result in improved caching benefits as certain data structures just have to be initialized once and can be reused multiple times. This mode of operation may improve performance when altering the git database on a low level, and is clearly beneficial on operating systems where command invocations are very slow.
-
-****************
-Object Databases
-****************
-An object database provides a simple interface to query object information or to write new object data. Objects are generally identified by their 20 byte binary sha1 value during query.
-
-GitPython uses the ``gitdb`` project to provide a pure-python implementation of the git database, which includes reading and writing loose objects, reading pack files and handling alternate repositories.
-
-The great thing about this is that ``Repo`` objects can use any object database, hence it easily supports different implementations with different performance characteristics. If you are thinking in extremes, you can implement your own database representation, which may be more efficient for what you want to do specifically, like handling big files more efficiently.
-
-************************
-Reduced Memory Footprint
-************************
-Objects, such as commits, tags, trees and blobs now use 20 byte sha1 signatures internally, reducing their memory demands by 20 bytes per object, allowing you to keep more objects in memory at the same time. 
-
-The internal caches of tree objects were improved to use less memory as well.

Subject: fix(index): improve LockedFD handling

Relying on the destructor will not work, even though
the code used to rely on it.

Now we handle failures more explicitly. Far from perfect,
but a good start for a fix.

Subject: src, #519: Improve daemon launch so Win does not stuck

+ Retrofit try...finally blocks to ensure killing the daemon - now
vulnerable also on Windows due to Popen() + CREATE_NEW_PROCESS_GROUP
- BUT `test_base.test_with_rw_remote_and_rw_repo()` TC fails in MINGW
due to invalid remote-URL in fetching-repo's config. Another day.
- NEXT FREEZE to solve: test-diff_interface() under MINGW!

Subject: Win, #519: FIX undead Git-daemon on Windows

+ On MINGW-git, daemon exists but if invoked as 'git daemon', DAEMON
CANNOT DIE!
+ So, launch `git-daemon` on Apveyor, but
- remote TCs fail due to paths problems.
+ Updated README instructions on Windows.
+ Restore disabled remote TCs on Windows.
+ Disable failures on daemon-tests only the last moment
  (raise SkipTest) so when ready, it will also pass.

Subject: Win, #519: Remove `git.cmd` failback - no longer exists.

+ Simplify call_process, no win-code case, no `make_call()` nested func.
+ Del needless WinError try..catch, in `_call_process()` already
converted as GitCommandNotFound by `execute()`.
+ pyism: kw-loop-->comprehension, facilitate debug-stepping

 ### REQUIREMENTS
 
-GitPython needs the `git` executable to be installed on the system and available in your `PATH` for most operations. If it is not in your `PATH`, you can help GitPython find it by setting the `GIT_PYTHON_GIT_EXECUTABLE=<path/to/git>` environment variable.

Subject: io, dif: #519: FIX DIFF freeze when reading from GIL

+ CAUSE: In Windows, Diffs freeze while reading Popen streams,
probably buffers smaller; good-thin(TM) in this case because reading a
Popen-proc from the launching-thread freezes GIL.  The alternative to
use `proc.communicate()` also relies on big buffers.
+ SOLUTION: Use `cmd.handle_process_output()` to consume Diff-proc
streams.
+ Retroffited `handle_process_output()` code to support also
byte-streams, both Threading(Windows) and Select/Poll (Posix) paths
updated.

- TODO: Unfortunately, `Diff._index_from_patch_format()` still slurps
input; need to re-phrase header-regexes linewise to resolve it.

Subject: Win, hook, #519: Consume Hook Popen-proc out of GIL

+ HookException thrown on Popen, and were missed on Windows.
+ No SHELL on Popen??
+ Minor fixes:
  + Try harder to delete trees - no remorses.
  + Simplify exception reprs.
  + Unittest-ize test_index assertions.

Subject: repo-TCs, #519: FIX config resource leaks

+ Modify lock/read-config-file code to ensure files closed.
+ Use `with GitConfigarser()` more systematically in TCs.
+ Clear any locks left hanging from prev Tcs.
+ Util: mark lock-files as SHORT_LIVED; save some SSDs...

Subject: Win, #519: FIX repo TCs.

+ FIX TestRepo.test_submodule_update():
  + submod: del `.git` file prior overwrite; Windows denied otherwise!
+ FIX TestRepo.test_untracked_files():
  + In the `git add <file>` case, it failed with unicode args on PY2.
Had to
encode them with `locale.getpreferredencoding()` AND use SHELL.
+ cmd: add `shell` into `execute()` kwds, for overriding USE_SHELL per
command.
+ repo: replace blocky `communicate()` in `_clone()` with thread-pumps.
+ test_repo.py: unittestize (almost  all) assertions.
+ Replace open --> with open for index (base and TC).
+ test_index.py: Enabled a dormant assertion.

 The special :class:`RootModule <git.objects.submodule.root.RootModule>` type allows you to treat your master repository as root of a hierarchy of submodules, which allows very convenient submodule handling. Its ``update(...)`` method is reimplemented to provide an advanced way of updating submodules as they change their values over time. The update method will track changes and make sure your working tree and submodule checkouts stay consistent, which is very useful in case submodules get deleted or added to name just two of the handled cases.
 
-Additionally, GitPython adds functionality to track a specific branch, instead of just a commit. Supported by customized update methods, you are able to automatically update submodules to the latest revision available in the remote repository, as well as to keep track of changes and movements of these submodules. To use it, set the name of the branch you want to track to the ``submodule.$name.branch`` option of the *.gitmodules*  file, and use GitPython update methods on the resulting repository with the ``to_latest_revision`` parameter turned on. In the latter case, the sha of your submodule will be ignored, instead a local tracking branch will be updated to the respective remote branch automatically, provided there are no local changes. The resulting behaviour is much like the one of svn::externals, which can be useful in times.
