|
1 | == New Features == | |
|
|
2 | ||
|
|
3 | * `hg config` now has a `--source` option to show where each | |
|
|
4 | configuration value comes from. | |
|
|
5 | * Introduced a command (debug-repair-issue6533) to repair repositories affected | |
|
|
6 | by issue6528 where certain files would show up as modified even if they were | |
|
|
7 | clean due to an issue in the copy-tracing code. | |
|
|
8 | ||
|
|
9 | == Default Format Change == | |
|
|
10 | ||
|
|
11 | These changes affect newly created repositories (or new clone) done with | |
|
|
12 | Mercurial 5.9. | |
|
|
13 | ||
|
|
14 | ||
|
|
15 | == New Experimental Features == | |
|
|
16 | ||
|
|
17 | * A `changelogv2` format has been introduced. It is not ready for use yet, but | |
|
|
18 | will be used later to address some of the weaknesses of the current revlog | |
|
|
19 | format. | |
|
|
20 | * Initial experiment and support for `dirstatev2`, a new dirstate format that | |
|
|
21 | addresses some of the weaknesses of the current dirstate format. Python + C | |
|
|
22 | and Rust support are being implemented, but the Rust solution is the one | |
|
|
23 | currently getting the attention for performance. | |
|
|
24 | * Initial support for `rhg status`. `rhg` is the Rust wrapper executable for hg | |
|
|
25 | that shortcuts some commands for faster execution speed. | |
|
|
26 | ||
|
|
27 | == Bug Fixes == | |
|
|
28 | ||
|
|
29 | * Fixed a regression (in 5.9.1) introduced in 5.9 when cloning repos with | |
|
|
30 | deep filenames | |
|
|
31 | * Fixed detection of directories becoming symlinks, but only when using the | |
|
|
32 | Rust extensions. | |
|
|
33 | * Fixed ignore and include not composing in the Rust status | |
|
|
34 | * `hg commit --interactive` now handles deselecting edits of a rename | |
|
|
35 | * Fixed a case where `hg evolve` gives different results when interrupted | |
|
|
36 | * Fixed a memory leak in phases computation | |
|
|
37 | * `histedit` and `shelve` don't swallow errors when updating the working copy | |
|
|
38 | anymore | |
|
|
39 | * Improve error message when detecting content-divergence with a hidden | |
|
|
40 | common predecessor | |
|
|
41 | * No longer re-order parents in filelog, see issue6533 | |
|
|
42 | * Fix revisions affected by issue6533 on the fly during exchange | |
|
|
43 | * Many Windows fixes for stability and py3 compatibility improvements | |
|
|
44 | * Many other miscellaneous fixes | |
|

46 | == Backwards Compatibility Changes == | |
|
|
47 | ||
|
|
48 | ||
|
|
49 | == Internal API Changes == | |
|
|
50 | ||
|
|
51 | The Dirstate API have been updated as the previous function leaked some | |
|
|
52 | internal details and did not distinguish between two important cases: "We are | |
|
|
53 | changing parent and need to adjust the dirstate" and "some command is changing | |
|
|
54 | which file is tracked". To clarify the situation: | |
|
|
55 | ||
|
|
56 | * the following functions have been deprecated, | |
|
|
57 | ||
|
|
58 | - `dirstate.add`, | |
|
|
59 | - `dirstate.normal`, | |
|
|
60 | - `dirstate.normallookup`, | |
|
|
61 | - `dirstate.merge`, | |
|
|
62 | - `dirstate.otherparent`, | |
|
|
63 | - `dirstate.remove`, | |
|
|
64 | - `dirstate.drop`, | |
|
|
65 | - `dirstateitem.__getitem__`, | |
|
|
66 | ||
|
|
67 | * these new functions are added for the "adjusting parents" use-case: | |
|
|
68 | ||
|
|
69 | - `dirstate.update_file`, | |
|
|
70 | - `dirstate.update_file_p1`, | |
|
|
71 | ||
|
|
72 | * these new function are added for the "adjusting wc file" use-case": | |
|
|
73 | ||
|
|
74 | - `dirstate.set_tracked`, | |
|
|
75 | - `dirstate.set_untracked`, | |
|
|
76 | - `dirstate.set_clean`, | |
|
|
77 | - `dirstate.set_possibly_dirty`, | |
|
|
78 | ||
|
|
79 | See inline documentation of the new functions for details. | |
|
|
80 | ||
|
|
81 | * Additionally, the following have been deprecated: | |
|
|
82 | - `urlutil.getpath` function | |
|
|
83 | - `localrepository.updatecaches`' `full` argument | |
|
|
84 | ||
|
|
85 | * The following have been removed: | |
|
|
86 | - `revlog.revlogio` has been removed | |
