7 | 7 | """remotefilelog causes Mercurial to lazilly fetch file contents (EXPERIMENTAL) |
|
8 | 8 | |
|
9 | 9 | This extension is HIGHLY EXPERIMENTAL. There are NO BACKWARDS COMPATIBILITY |
|
10 | 10 | GUARANTEES. This means that repositories created with this extension may |
|
11 | 11 | only be usable with the exact version of this extension/Mercurial that was |
|
12 | 12 | used. The extension attempts to enforce this in order to prevent repository |
|
13 | 13 | corruption. |
|
14 | 14 | |
|
15 | 15 | remotefilelog works by fetching file contents lazily and storing them |
|
16 | 16 | in a cache on the client rather than in revlogs. This allows enormous |
|
17 | 17 | histories to be transferred only partially, making them easier to |
|
18 | 18 | operate on. |
|
19 | 19 | |
|
20 | 20 | Configs: |
|
21 | 21 | |

|
51 | 51 | ``remotefilelog.data.generations`` list for specifying the lower bound of |
|
52 | 52 | each generation of the data pack files. For example, list ['100MB','1MB'] |

|
54 | 54 | 1MB, 100MB) and [100MB, infinity). |
|
55 | 55 | |
|
56 | 56 | ``remotefilelog.data.maxrepackpacks`` the maximum number of pack files to |

68 | 68 | |
|
69 | 69 | ``remotefilelog.history.generations`` list for specifying the lower bound of |
|
70 | 70 | each generation of the history pack files. For example, list [ |

|
72 | 72 | 0, 1MB), [1MB, 100MB) and [100MB, infinity). |
