cykooz.recipe.patch 0.1

多个补丁

如果您要应用多个补丁

>>> write(sample_buildout, 'another.patch',
... """diff --git demo.py demo.py
... --- demo.py
... +++ demo.py
... @@ -1,2 +1 @@
... -# demo egg
...  # patching
... """)

更新您的buildout.cfg以列出新的补丁。在这种情况下，另一个.patch应在demo.patch之后应用

>>> write(sample_buildout, 'buildout.cfg',
... """
... [buildout]
... parts = demo-patch
... index = demo/dist/
...
... [demo-patch]
... recipe = cykooz.recipe.patch
... egg = demo==1.0
... patches =
...     demo.patch
...     another.patch
... """)

运行buildout会给我们

>>> rmdir(sample_buildout, 'develop-eggs', demoegg)
>>> remove(sample_buildout, '.installed.cfg')
>>> _ = system(buildout + ' setup demo bdist_egg')
>>> print_(system(buildout))

>>> cat(sample_buildout, 'develop-eggs', demoegg, 'demo.py')
# patching

修复安装在其他部分的egg

另一种可能性是使用zc.recipe.egg（或可能任何其他recipe）安装egg，然后对其进行修复。但是，必须解压缩安装egg，并且egg可能最终会出现在eggs文件夹而不是develop-eggs文件夹中。

>>> write(sample_buildout, 'buildout.cfg',
... """
... [buildout]
... parts = demo-egg demo-patch
... index = demo/dist/
...
... [demo-egg]
... recipe = zc.recipe.egg
... eggs = demo==1.0
...
... [demo-patch]
... recipe = cykooz.recipe.patch
... egg = ${demo-egg:eggs}
... patches = demo.patch
... """)

运行buildout会给我们

>>> rmdir(sample_buildout, 'develop-eggs', demoegg)
>>> remove(sample_buildout, '.installed.cfg')
>>> _ = system(buildout + ' setup demo bdist_egg')
>>> print_(system(buildout))

>>> ls(sample_buildout, 'eggs', demoegg)

>>> cat(sample_buildout, 'demo', 'demo.py')
# demo egg
>>> cat(sample_buildout, 'eggs', demoegg, 'demo.py')
# demo egg
# patching

损坏的补丁

如果其中一个补丁损坏

>>> write(sample_buildout, 'missing-file.patch',
... """diff --git missing-file.py missing-file.py
... --- missing-file.py
... +++ missing-file.py
... @@ -1,2 +0 @@

当您尝试应用多个补丁时，它将无法应用任何后续的补丁，让您修复问题
