9 | * Phases have been reworked to improve their general performance | |||
|
|
10 | * revset: stop serializing node when using "%ln" | |||
|
|
11 | * phases: convert remote phase root to node while reading them | |||
|
|
12 | * phases: use revision number in new_heads | |||
|
|
13 | * phases: use revision number in analyze_remote_phases | |||
|
|
14 | * phases: stop using `repo.set` in `remotephasessummary` | |||
|
|
15 | * phases: move RemotePhasesSummary to revision number | |||
|
|
16 | * phases: use revision number in `_pushdiscoveryphase` | |||
|
|
17 | * phases: introduce a performant efficient way to access revision in a set | |||
|
|
18 | * phases: rework the logic of _pushdiscoveryphase to bound complexity | |||
|
|
19 | * The Rust working copy code is being used by more places now: | |||
|
|
20 | * matchers: support patternmatcher in rust | |||
|
|
21 | * dirstate: remove the python-side whitelist of allowed matchers | |||
|
|
22 | * stream-clone: disable gc for `_entries_walk` duration | |||
|
|
23 | * stream-clone: disable gc for the initial section for the v3 format | |||
|
|
24 | * postincoming: avoid computing branchhead if no report will be posted | |||
|
|
25 | * stream-clone: disable gc for the entry listing section for the v2 format | |||
|
|
26 | * perf: allow profiling of more than one run | |||
|
|
27 | * perf: run the gc before each run | |||
|
|
28 | * perf: start recording total time after warming | |||
|
|
29 | * perf: clear vfs audit_cache before each run | |||
|
|
30 | * outgoing: rework the handling of the `missingroots` case to be faster | |||
|
|
31 | * outgoing: add a simple fastpath when there is no common | |||
|
|
32 | * tags-cache: skip the filternode step if we are not going to use it | |||
|
|
33 | * tags-cache: directly operate on rev-num warming hgtagsfnodescache | |||
|
|
34 | * tags-cache: directly perform a monimal walk for hgtagsfnodescache warming | |||
|
|
35 | * exchange: improve computation of relevant markers for large repos | |||

|
|
40 | * Introduce a new experimental branch cache "v3": | |||
|
|
41 | * branchcache: add more test for the logic around obsolescence and branch heads | |||
|
|
42 | * branchcache: skip entries that are topological heads in the on disk file | |||
|
|
43 | * branchcache: add a "pure topological head" fast path | |||
|
|
44 | * branchcache: allow to detect "pure topological case" for branchmap | |||
|

|
50 | * perf-stream-locked-section: fix the call to the v3 generator | |||
|
|
51 | * perf-stream-locked-section: advertise the right version key in the help | |||
|
|
52 | * stream: in v3, skip the "size" fast path if the entries have some unknown size | |||
|
|
53 | * stream-clone: stop getting the file size of all file in v3 | |||
|
|
54 | * streamclone: stop listing files for entries that have no volatile files | |||
