pytype: import typing directly First we no longer needs the pycompat layer, second having the types imported in all case will allow to use them more directly in type annotation, something important to upgrade the old "type comment" to proper type annotation. A lot a stupid assert are needed to keep pyflakes happy. We should be able to remove most of them once the type comment have been upgraded.

usage: configure uncompressed chunk cache through resource configuration Let's use this new concept for what it is meant for. This provides a sizable speed up for reading multiple revision for some complexe repositories. ### data-env-vars.name = pypy-2018-08-01-zstd-sparse-revlog # benchmark.name = hg.perf.read-revisions # benchmark.variants.order = reverse memory-medium: 1.892400 memory-high: 1.722934 (-8.61%) # benchmark.variants.order = default memory-medium: 1.751542 memory-high: 1.589340 (-9.49%)

usage: add configuration option to adjust resources usage They currently do nothing, but this open the way to actually use them.

usage: add a `usage.repository-role` config This config will be used for behavior and performance adjustment depending of the repository role.

common-pattern: cover "elapsed time" line These are perfect targets for the common-pattern matching.

bundle: do not detect --base argument that match nothing as lack of argument With the previous version of the code, if --base did not match anything, it will be handled as if no --base was provided and will fallback to using discovery with the default path. This has two issues : - The resulting bundle won't match what the user requested, - if not default path is configured, it will crash. We now properly distinct between the two cases and if the --base query does not find any changeset, we will assume that everything under --rev needs to be sent.
