templater: stop accepting a single style to stylemap() The code seems to have been for compatibility across d3dbdca92458 (hgweb: don't choke when an inexistent style is requested (issue1901), 2009-11-12). Differential Revision: https://phab.mercurial-scm.org/D8844

formatter: inline a variable assigned from `templater.templater.frommapfile` The variable doesn't get reused and it doesn't help formatting, so I don't see any reason for it. Differential Revision: https://phab.mercurial-scm.org/D8807

templater: don't normalize path separators to '/' when interacting with OS `_readmapfile()` is about reading a map file from the file system, so we shouldn't use our `util.normpath()`, which also normalizes `os.sep` to '/'. Differential Revision: https://phab.mercurial-scm.org/D8806

formatter: remove now-unnecessary check for file-ness `templater.templatepath()` now returns non-`None` only for files, so the caller doesn't have to check. Differential Revision: https://phab.mercurial-scm.org/D8805

templater: make templatepath() not return directory paths The previous patch added a test showing an unusal error message. This make it more like other error messages. Differential Revision: https://phab.mercurial-scm.org/D8804

tests: show unusual error message for `hg log --style coal` It turns out that we show the full path when the given style name matches a subdirectory of `mercurial/templates/`. Differential Revision: https://phab.mercurial-scm.org/D8803

config: remove now-unused `abs` argument from `include` callback Differential Revision: https://phab.mercurial-scm.org/D8796

config: re-calculate absolute %include path in `include` callback This removes the last user of the `abs` argument for the `include` callback. The next patch will remove the argument. Differential Revision: https://phab.mercurial-scm.org/D8795

subrepoutil: use relative path for looking up config `%include`s The code was already working with relative paths in practice, since it passed in a (repo-)relative path into its local `read()` function. So all that this patch actually does is to switch to rename variables so we use the same path by a different name. This gets us closer to removing the "absolute" path from the `include` callback. Differential Revision: https://phab.mercurial-scm.org/D8794

config: remove now-unused support for "includepaths" This effectively undoes 081b08e4ea13 (templater: look for mapfiles in template paths, 2015-05-15). Differential Revision: https://phab.mercurial-scm.org/D8793

dispatch: adjust ui.flush() timing to stabilize test-blackbox.t Without this change, dispatch.dispatch() could return before flushing all stdio data.

clonebundles: document REQUIREDRAM key This is a follow-up to 72feaeb510b3, which introduced the feature. The key should be documented as part of the format specification inside the extension docstring. Differential Revision: https://phab.mercurial-scm.org/D8838

commitctx: gather more code dealing with copy-in-extra Now that we have a function that deal with the copy-in-extra special case, we can gather more code meant to deal with this special case. Making the rest of the code simpler.

commitctx: rename files to touched in a couple of place This is a clearer word that we will use increasingly over this series. It also make the old variable name available to another usage :-)

commitctx: extract copy information encoding into extra into commit.py The encoding of copy information into extra has multiple subcases and become quite complicated (eg: empty list can be explicitly or implicitly stored for example). In addition, it is niche experimental feature since as it affect the hash, it is only suitable for user who don't mercurial for storage server side (ie: Google). Having this complexity part of the changelog will get in the way of further cleanup. We could have to either move more of that logic into the changelog or to move or extract more of the logic at the higher level. We take the second approach and start gather logic in dedicated function in commit.py.

commitctx: create the new extra dict on its own line A trivial move to make the next changeset easier to read.

commitctx: explicitly pass `manifest` to _commit_manifest As pointed out by Yuya Nishihara.

phabricator: unconditionally pop `test_vcr` to fix debugcallconduit 11592ce6a711 / D8525 accidentally broke debugcallconduit in non-test scenarios because it stopped popping `test_vcr` from `kwargs` unconditionally, so when `--test-vcr` isn't set the empty string still gets passed down as the value of `test_vcr` in `kwargs`. However unlike all the other commands debugcallconduit doesn't have an `**opts` argument to receive it, so it aborts because of invalid arguments. Differential Revision: https://phab.mercurial-scm.org/D8852

cleanup: fix bad formatting of state.py from D8811 `test-check-format.t` was failing for me. Do I just have the wrong version? Differential Revision: https://phab.mercurial-scm.org/D8841

dirstate: restore original estimation and update comment The former comment didn't reflect the content of the dirstate entries, the two nodes are a fixed header in the file and not per-entry. Split the documented entry into the path part and the fixed header. The heuristic itself is still valid, e.g. for the NetBSD src tree a maximum path size of 142 and an average of 49, resulting in 66 bytes per entry on average.

merge stable in default

commitctx: extract all the file preparation logic in a new function Before we actually start to create a new commit we have a large block of logic that do the necessary file and manifest commit and that determine which files are been affected by the commit (and how). This is a complex process on its own. It return a "simple" output that can be fed to the next step. The output itself is not that simple as we return a lot of individual items (files, added, removed, ...). My next step (and actual goal for this cleanup) will be to simplify the return by returning a richer object that will be more suited for the variation of data we want to store. After this changeset the `commitctx` is a collection of smaller function with limited scope. The largest one is still `_filecommit` without about 100 lines of code.

commitctx: gather more preparation code within the lock context This is a small change that exist mostly for clarification. I am about to move a large amount of code in its own function. having all that code next to each other will make the next changeset clearer.

commitctx: move a special case about files earlier Same logic as a changeset a bit earlier, the `writefilecopymeta` section is more a post processing details so we move the conditional about `files` value closer to the rest of the code computing `files` value.

commitctx: extract all the manual logic to process the files That branch of the if is significantly more complicated than the other two. Moving it to its own function make it simple to keep the scope limited and to read to the higher level function.

commitctx: treat `filesadded` more like `filesremoved` Accumulating the filename in a list will have a negligible cost and deal with the list of added files like the other ones will make is code cleaning simpler. The two variable with very close name is not great, but my plan is to split most of the code in a separated function which will make the "problem" go away by itself.

commitctx: move `writechangesetcopy` business at the end a code section This code is to handle a specific subcase so we move it a the end. This allow to gather the rest of the "core" code closer to the related logic.
