Faster git-fat for cygwin

Faster git-fat for cygwin

= Usage =

Copy all files (git-fat.{exe,py,pyc}) somewhere where your cygwin shell finds it ($PATH).

It runs only on cygwin (choose platform!). Msys requires other binaries are needed.

= How it works ? =

git-fat.exe is an simplified "python" executor which i executes python file directly via CPython C API. It takes it's executable PATH c:/tools/git-fat.exe and searches for

• c:/tools/git-fat.pyc
• c:/tools/git-fat.py and executes the first that is found.

There is no synchronization and/or automatic compilation .py -> .pyc. If you change .py, then either remove .pyc or recompile.pyc:

$ python -m compileall git-fat.py

= Changes =

v0.2 2015-02-11:

• fixed minor bugs
• readme is shown if 'git-fat.{py,pyc}' file is missing
• cygwin64 & cygwin32 binaries provided

v0.1s 2015-02-03:

• same, but with sources

v0.1 2015-02-03:

• initial version
• git-fat.exe starts git-fat.pyc or git-fat.py
• git-fat.py improvements:
  • don't start 2 git subprocesses on startup (GitFat constructor)
  • when doing checkout, pass 100 files to git checkout-index
• gives 2-3x performance speedup in some cases (git-fat initial pull, checkout etc ...)

= Source =

Sources (git-repos are here:)

• Patched git-fat: src/git-fat-zbigg
• win-py-spawner: src/win-py-spawner

= jenkins =

For now, to test how it behaves on jenkins, use:

rem Git-Fat optimization hack set PATH=d:\zzg_takietam\git-fat-cygwin;%PATH% bash -c "which git-fat"
