cykooz.recipe.patch的Python项目详细描述


这是emencia.recipe.patch的叉。主要区别是：

  • 添加了Python3支持。

支持的选项

配方支持以下选项：

路径

定义应用修补程序的目录。为了 示例：

path = src/some/directory/
鸡蛋

定义应该修补的鸡蛋。您还可以固定到特定的 版本。例如：

egg = some.egg<=1.1.1
补丁

修补程序文件的路径。这些补丁是按顺序应用的。为了 示例：

patches = patches/my_very_sprecial.patch
          patches/another_loverly.patch

示例用法

我们将修补的演示包：

>>> mkdir(sample_buildout, 'demo')
>>> write(sample_buildout, 'demo', 'README.txt', " ")
>>> write(sample_buildout, 'demo', 'demo.py',
... """# demo egg
... """)
>>> write(sample_buildout, 'demo', 'setup.py',
... """
... from setuptools import setup
...
... setup(
...     name = "demo",
...     version='1.0',
...     py_modules=['demo']
...     )
... """)
>>> print_(system(buildout + ' setup demo bdist_egg')) # doctest: +ELLIPSIS
Running setup script 'demo/setup.py'.
...

创建我们的修补程序：

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

让我们写出buildout.cfg来修补我们的演示包：

>>> 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
... """)

我们最终的egg名称取决于当前的python版本：

>>> import sys
>>> demoegg = 'demo-1.0-py%d.%d.egg' % sys.version_info[:2]

运行构建会给我们带来：

>>> print_(system(buildout))
Installing demo-patch.
Getting distribution for 'demo==1.0'.
Got demo 1.0.
patch: reading patch .../demo.patch
...
patch: patching file demo.py
patch: successfully patched .../demo-1.0...
...

>>> ls(sample_buildout, 'develop-eggs', demoegg)
d  EGG-INFO
-  demo.py
-  demo.pyc
-  demo.pyo
>>> cat(sample_buildout, 'demo', 'demo.py')
# demo egg
>>> cat(sample_buildout, 'develop-eggs', demoegg, 'demo.py')
# demo egg
# patching

多个补丁

如果要应用多个修补程序：

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

更新buildout.cfg以列出新补丁。在这种情况下， 另一个.patch应在demo之后应用。patch:

>>> 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
... """)

运行构建会给我们带来：

>>> rmdir(sample_buildout, 'develop-eggs', demoegg)
>>> remove(sample_buildout, '.installed.cfg')
>>> _ = system(buildout + ' setup demo bdist_egg')
>>> print_(system(buildout))
Installing demo-patch.
Getting distribution for 'demo==1.0'.
Got demo 1.0.
patch: reading patch .../demo.patch
...
patch: patching file demo.py
patch: successfully patched .../demo-1.0...
patch: reading patch .../another.patch
...
patch: patching file demo.py
patch: successfully patched .../demo-1.0...
...

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

修补安装在另一部分的鸡蛋

另一种可能是安装一个带有zc.recipe.egg（或 可能还有其他配方）然后补上。然而，它是 必须将鸡蛋拉开拉链，鸡蛋可能会在 鸡蛋文件夹代替发展鸡蛋文件夹。

>>> 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
... """)

运行构建会给我们带来：

>>> rmdir(sample_buildout, 'develop-eggs', demoegg)
>>> remove(sample_buildout, '.installed.cfg')
>>> _ = system(buildout + ' setup demo bdist_egg')
>>> print_(system(buildout))
Installing demo-egg.
Getting distribution for 'demo==1.0'.
Got demo 1.0.
Installing demo-patch.
patch: reading patch .../demo.patch
...
patch: patching file demo.py
patch: successfully patched .../demo-1.0...

>>> ls(sample_buildout, 'eggs', demoegg)
d  EGG-INFO
-  demo.py
-  demo.pyc
-  demo.pyo
>>> cat(sample_buildout, 'demo', 'demo.py')
# demo egg
>>> cat(sample_buildout, 'eggs', demoegg, 'demo.py')
# demo egg
# patching

破损斑块

如果其中一个修补程序损坏：

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

当您尝试应用多个修补程序时，它将无法应用任何 后续修补程序，让您修复问题：

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

运行构建会给我们带来：

>>> rmdir(sample_buildout, 'eggs', demoegg)
>>> remove(sample_buildout, '.installed.cfg')
>>> _ = system(buildout + ' setup demo bdist_egg')
>>> print_(system(buildout))
Installing demo-patch.
Getting distribution for 'demo==1.0'.
Got demo 1.0.
patch: reading patch .../missing-file.patch
...
patch: The next patch would delete the file missing-file.py,
patch: which does not exist!  Skipping patch.
patch: patch: **** malformed patch at line 6:

While:

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