simplemerge: let filemerge check for binary inputs This is similar to the previous patch, but here we put a specialized copy of `simplemerge._verifytext()` in the the `filemerge` module instead. Differential Revision: https://phab.mercurial-scm.org/D12147

simplemerge: let extension check for binary inputs (unless `--text`) The `simplemerge` module does too much UI-related things. This patch puts a specialized copy of `simplemerge._verifytext()` in the simplemerge extension. Differential Revision: https://phab.mercurial-scm.org/D12146

simplemerge: store input data in MergeInput I want to be able to update the file contents for support for partial conflict resolution. Having the text available (and later settable) on `MergeInput` will enable that. Differential Revision: https://phab.mercurial-scm.org/D12144

simplemerge: convert MergeInput to regular, non-attr.ib class I'm about to add more logic and state to it. Differential Revision: https://phab.mercurial-scm.org/D12145

simplemerge: replace `**opts` passed to `simplemerge()` by keyword arguments The `simplemerge` module is library code; it should not get an unmodified `opts` dict from the `simplemerge` extension. Differential Revision: https://phab.mercurial-scm.org/D12152

automation: use gp3 volume type This is a newer volume type. It offers a better baseline of performance by default and is ~10% cheaper. It doesn't offer burst credits. But its performance is guaranteed, unlike gp2, which had wonky performance behavior. Differential Revision: https://phab.mercurial-scm.org/D12132

automation: use m6i instances This instance type is much, much faster than t3 and can perform tasks much quicker. Differential Revision: https://phab.mercurial-scm.org/D12131

narrow: add support for merging add and remove outside of the tracked set This extend f1eb77dceb36 to test and support the remaining action. Or, at least, the simple incarnation of them. Differential Revision: https://phab.mercurial-scm.org/D12181

status: prefer relative paths in Rust code … when the repository root is under the current directory, so the kernel needs to traverse fewer directory in every call to `read_dir` or `symlink_metadata`. Better yet would be to use libc functions like `openat` and `fstatat` to remove such repeated traversals entirely, but the standard library does not provide APIs based on those. Maybe with a crate like https://crates.io/crates/openat instead? Benchmarks of `rhg status` show that this patch is neutral in some configurations, and makes the command up to ~20% faster in others. Below is semi-arbitrary subset of results. The four numeric columns are: time (in seconds) with this changeset’s parent, time with this changeset, time difference (negative is better), time ratio (less than 1 is better). ``` mercurial-dirstate-v1 | default-plain-clean.no-iu.pbr | 0.0061 -> 0.0059: -0.0002 (0.97) mercurial-dirstate-v2 | default-plain-clean.no-iu.pbr | 0.0029 -> 0.0028: -0.0001 (0.97) mozilla-dirstate-v1 | default-plain-clean.no-iu.pbr | 0.2110 -> 0.2102: -0.0007 (1.00) mozilla-dirstate-v2 | default-copies-clean.ignored.pbr | 0.0489 -> 0.0401: -0.0088 (0.82) mozilla-dirstate-v2 | default-copies-clean.no-iu.pbr | 0.0479 -> 0.0393: -0.0085 (0.82) mozilla-dirstate-v2 | default-copies-large.all.pbr | 0.1262 -> 0.1210: -0.0051 (0.96) mozilla-dirstate-v2 | default-copies-small.ignored-unknown.pbr | 0.1262 -> 0.1200: -0.0062 (0.95) mozilla-dirstate-v2 | default-copies-small.ignored.pbr | 0.0536 -> 0.0417: -0.0119 (0.78) mozilla-dirstate-v2 | default-copies-small.no-iu.pbr | 0.0482 -> 0.0393: -0.0089 (0.81) mozilla-dirstate-v2 | default-plain-clean.ignored.pbr | 0.0518 -> 0.0402: -0.0116 (0.78) mozilla-dirstate-v2 | default-plain-clean.no-iu.pbr | 0.0481 -> 0.0392: -0.0088 (0.82) mozilla-dirstate-v2 | default-plain-large.all.pbr | 0.1271 -> 0.1218: -0.0052 (0.96) mozilla-dirstate-v2 | default-plain-small.ignored-unknown.pbr | 0.1225 -> 0.1202: -0.0022 (0.98) mozilla-dirstate-v2 | default-plain-small.ignored.pbr | 0.0510 -> 0.0418: -0.0092 (0.82) mozilla-dirstate-v2 | default-plain-small.no-iu.pbr | 0.0480 -> 0.0394: -0.0086 (0.82) netbeans-dirstate-v1 | default-plain-clean.no-iu.pbr | 0.1442 -> 0.1422: -0.0020 (0.99) netbeans-dirstate-v2 | default-plain-clean.no-iu.pbr | 0.0325 -> 0.0282: -0.0043 (0.87) ``` Differential Revision: https://phab.mercurial-scm.org/D12175
