1 | 1 | Repositories contain a file (``.hg/requires``) containing a list of |
|
2 | 2 | features/capabilities that are *required* for clients to interface |
|
3 | 3 | with the repository. This file has been present in Mercurial since |
|
4 | 4 | version 0.9.2 (released December 2006). |
|
5 | 5 | |
|
6 | 6 | One of the first things clients do when opening a repository is read |
|
7 | 7 | ``.hg/requires`` and verify that all listed requirements are supported, |
|
8 | 8 | aborting if not. Requirements are therefore a strong mechanism to |
|
9 | 9 | prevent incompatible clients from reading from unknown repository |
|
10 | 10 | formats or even corrupting them by writing to them. |
|
11 | 11 | |
|
12 | 12 | Extensions may add requirements. When they do this, clients not running |
|
13 | 13 | an extension will be unable to read from repositories. |
|
14 | 14 | |
|
15 | 15 | The following sections describe the requirements defined by the |
|
16 | 16 | Mercurial core distribution. |
|
17 | 17 | |
|
18 | 18 | revlogv1 |
|
19 | 19 | ======== |
|
20 | 20 | |
|
21 | 21 | When present, revlogs are version 1 (RevlogNG). RevlogNG was introduced |
|
22 | 22 | in 2006. The ``revlogv1`` requirement has been enabled by default |
|
23 | 23 | since the ``requires`` file was introduced in Mercurial 0.9.2. |
|
24 | 24 | |
|
25 | 25 | If this requirement is not present, version 0 revlogs are assumed. |
|
26 | 26 | |
|
27 | 27 | store |
|
28 | 28 | ===== |
|
29 | 29 | |
|
30 | 30 | The *store* repository layout should be used. |
|
31 | 31 | |
|
32 | 32 | This requirement has been enabled by default since the ``requires`` file |
|
33 | 33 | was introduced in Mercurial 0.9.2. |
|
34 | 34 | |
|
35 | 35 | fncache |
|
36 | 36 | ======= |
|
37 | 37 | |
|
38 | 38 | The *fncache* repository layout should be used. |
|
39 | 39 | |
|
40 | 40 | The *fncache* layout hash encodes filenames with long paths and |
|
41 | 41 | encodes reserved filenames. |
|
42 | 42 | |
|
43 | 43 | This requirement is enabled by default when the *store* requirement is |
|
44 | 44 | enabled (which is the default behavior). It was introduced in Mercurial |
|
45 | 45 | 1.1 (released December 2008). |
|
46 | 46 | |
|
47 | 47 | shared |
|
48 | 48 | ====== |
|
49 | 49 | |
|
50 | 50 | Denotes that the store for a repository is shared from another location |
|
51 | 51 | (defined by the ``.hg/sharedpath`` file). |
|
52 | 52 | |
|
53 | 53 | This requirement is set when a repository is created via :hg:`share`. |
|
54 | 54 | |
|
55 | 55 | The requirement was added in Mercurial 1.3 (released July 2009). |
|
56 | 56 | |
|
57 | 57 | relshared |
|
58 | 58 | ========= |
|
59 | 59 | |
|
60 | 60 | Derivative of ``shared``; the location of the store is relative to the |
|
61 | 61 | store of this repository. |
|
62 | 62 | |
|
63 | 63 | This requirement is set when a repository is created via :hg:`share` |
|
64 | 64 | using the ``--relative`` option. |
|
65 | 65 | |
|
66 | 66 | The requirement was added in Mercurial 4.2 (released May 2017). |
|
67 | 67 | |
|
68 | 68 | dotencode |
|
69 | 69 | ========= |
|
70 | 70 | |
|
71 | 71 | The *dotencode* repository layout should be used. |
|
72 | 72 | |
|
73 | 73 | The *dotencode* layout encodes the first period or space in filenames |
|
74 | 74 | to prevent issues on OS X and Windows. |
|
75 | 75 | |
|
76 | 76 | This requirement is enabled by default when the *store* requirement |
|
77 | 77 | is enabled (which is the default behavior). It was introduced in |
|
78 | 78 | Mercurial 1.7 (released November 2010). |
|
79 | 79 | |
|
80 | 80 | parentdelta |
|
81 | 81 | =========== |
|
82 | 82 | |
|
83 | 83 | Denotes a revlog delta encoding format that was experimental and |
|
84 | 84 | replaced by *generaldelta*. It should not be seen in the wild because |
|
85 | 85 | it was never enabled by default. |
|
86 | 86 | |
|
87 | 87 | This requirement was added in Mercurial 1.7 and removed in Mercurial |
|
88 | 88 | 1.9. |
|
89 | 89 | |
|
90 | 90 | generaldelta |
|
91 | 91 | ============ |
|
92 | 92 | |
|
93 | 93 | Revlogs should be created with the *generaldelta* flag enabled. The |
|
94 | 94 | generaldelta flag will cause deltas to be encoded against a parent |
|
95 | 95 | revision instead of the previous revision in the revlog. |
|
96 | 96 | |
|
97 | 97 | Support for this requirement was added in Mercurial 1.9 (released |
|
98 | 98 | July 2011). The requirement was disabled on new repositories by |
|
99 | 99 | default until Mercurial 3.7 (released February 2016). |
|
100 | 100 | |
|
101 | 101 | manifestv2 |
|
102 | 102 | ========== |
|
103 | 103 | |
|
104 | 104 | Denotes that version 2 of manifests are being used. |
|
105 | 105 | |
|
106 | 106 | Support for this requirement was added in Mercurial 3.4 (released |
|
107 | 107 | May 2015). The new format failed to meet expectations and support |
|
108 | 108 | for the format and requirement were removed in Mercurial 4.6 |
|
109 | 109 | (released May 2018) since the feature never graduated frome experiment |
|
110 | 110 | status. |
|
111 | 111 | |
|
112 | 112 | treemanifest |
|
113 | 113 | ============ |
|
114 | 114 | |
|
115 | 115 | Denotes that tree manifests are being used. Tree manifests are |
|
116 | 116 | one manifest per directory (as opposed to a single flat manifest). |
|
117 | 117 | |
|
118 | 118 | Support for this requirement was added in Mercurial 3.4 (released |
|
119 | 119 | August 2015). The requirement is currently experimental and is |
|
120 | 120 | disabled by default. |
|
121 | 121 | |
|
122 | 122 | exp-sparse |
|
123 | 123 | ========== |
|
124 | 124 | |
|
125 | 125 | The working directory is sparse (only contains a subset of files). |
|
126 | 126 | |
|
127 | 127 | Support for this requirement was added in Mercurial 4.3 (released |
|
128 | 128 | August 2017). This requirement and feature are experimental and may |
|
129 | 129 | disappear in a future Mercurial release. The requirement will only |
|
130 | 130 | be present on repositories that have opted in to a sparse working |
|
131 | 131 | directory. |
|
132 | 132 | |
|
133 | 133 | bookmarksinstore |
|
134 | 134 | ================== |
|
135 | 135 | |
|
136 | 136 | Bookmarks are stored in ``.hg/store/`` instead of directly in ``.hg/`` |
|
137 | 137 | where they used to be stored. The active bookmark is still stored |
|
138 | 138 | directly in ``.hg/``. This makes them always shared by ``hg share``, |
|
139 | 139 | whether or not ``-B`` was passed. |
|
140 | 140 | |
|
141 | 141 | Support for this requirement was added in Mercurial 5.1 (released |
|
142 | 142 | August 2019). The requirement will only be present on repositories |
|
143 | 143 | that have opted in to this format (by having |
|
144 | 144 | ``format.bookmarks-in-store=true`` set when they were created). |
|
145 | ||
|
146 | persistent-nodemap | |
|
147 | ================== | |
|
148 | ||
|
149 | The `nodemap` index (mapping nodeid to local revision number) is persisted on | |
|
150 | disk. This provides speed benefit (if the associated native code is used). The | |
|
151 | persistent nodemap is only used for two revlogs: the changelog and the | |
|
152 | manifestlog. | |
|
153 | ||
|
154 | Support for this requirement was added in Mercurial 5.5 (released August 2020). | |
|
155 | Note that as of 5.5, only installations compiled with the Rust extension will | |
|
156 | benefit from a speedup. The other installations will do the necessary work to | |
|
157 | keep the index up to date, but will suffer a slowdown. |
