This patch adds the support for `ushelve` in `hg continue` plan. `hgcontinueunshelve()` has been created for independent calls. In case an interrupted unshelve is resumed via hg continue the shelvedstate needs to be loaded seperately. This has been ensured by `_loadunshelvedstate()` `hgcontinueunshelve()` is then registered as `continuefunc` for state detection API. Results are shown as tests.

This is part of GSoC19 project `Implement abort and continue commands`. This patch is part of the continue plan. This adds the basic logic for hg continue. This command aborts an multistep operation like graft, histedit, rebase, transplant and unshelve if they are in an unfinished state. The first part of the logic is determining the unfinished operation from the state detection API under statemod. This API is extended to support hg continue by adding a method to register the abort logic as a function (here continuefunc). Once the unfinished operation is determined the registered logic is used to resume the command in case it is interrupted. The benefit of this kind of framework is that any new extension developed can support hg continue by registering the command and logic under statedetection API. hg continue currently supports --dry-run/-n flag only. It is used to dry run hg abort Differential Revision: https://phab.mercurial-scm.org/D6645

Many interesting changes have happened in Rust since the Oxidation Plan was introduced, like the 2018 edition and procedural macros: - Opting in to the 2018 edition is a clear benefit in terms of future proofing, new (nice to have) syntactical sugar notwithstanding. It also has a new non-lexical, non-AST based borrow checker that has fewer bugs(!) and allows us to write correct code that in some cases would have been rejected by the old one. - Procedural macros allow us to use the PyO3 crate which maintainers have expressed the clear goal of compiling on stable, which would help in code maintainability compared to rust-cpython. In this patch are the following changes: - Removing most `extern crate` uses - Updating `use` clauses (`crate` keyword, nested `use`) - Removing `mod.rs` in favor of an aptly named module file Like discussed in the mailing list ( https://www.mercurial-scm.org/pipermail/mercurial-devel/2019-July/132316.html ), until Rust integration in Mercurial is considered to be out of the experimental phase, the maximum version of Rust allowed is whatever the latest version Debian packages.

branchmap.branchcache, among other classes, defines a iteritems(). That currently gets replaced by items() by the source transformer. That makes it harder for extensions to work with both py2 and py3, since they have to call either items() or iteritems() on branchcache. Let's not replace definitions of iteritems() (and itervalues()) and only replace the call-sites. We need to also add an items() alias to branchcache (etc) so our transformer call-sites will find it.

This adds support of `hg merge --abort` to `hg abort` plan. This involves refactoring `hg.merge` into two different functions removing the abort logic of `merge` from `hg.merge` and then creating a seperate `hg.abortmerge` to handle the abort logic so that the abortion of merge can be called independently. `hg.abortmerge` is then registered as `abortfunc` for the state detection API so that `commands.abort` can use it to deal with an unfinished merge operation.

This patch adds the support for shelve in `hg abort` plan. For this the logic to load a `shelvedstate` and the error handling for it had been shifted to a seperate function `_loadunshelvedstate()`. This returns a tuple with `state` file and `opts.` `hgabortunshelve()` has been created for independent calls. In case abortion of `unshelve` is called via `hg abort` the `shelvedstate` needs to be loaded seperately.

As in the previous patch, consider these two histories: @ 4 'rename x to y' | o 3 'add x again' | o 2 'remove x' | | o 1 'modify x' |/ o 0 'add x' @ 4 'rename x to y' | o 3 'add x again' | | o 2 'modify x' | | | o 1 'add x' |/ o 0 'base' We trace copies from the 'modify x' commit to commit 4 by going via the merge base (commit 0). When tracing file 'y' (_tracefile()) in the first case, we immediately find the rename from 'x'. We check to see if 'x' exists in the merge base, which it does, so we consider it a valid copy. In the second case, 'x' does not exist in the merge base, so it's not considered a valid copy. As a workaround, this patch makes it so we also attempt the check in mergecopies's base commit (commit 1 in the second case). That feels pretty ugly to me, but I don't have any better ideas. Note that we actually also check not only that the filename matches, but also that the file's nodeid matches. I don't know why we do that, but it was like that already before I rewrote mergecopies(). That means that the rebase will still fail in cases like this (again, it already failed before my rewrite): @ 4 'rename x to y' | o 3 'add x again with content X2' | o 2 'remove x' | | o 1 'modify x to content X2' |/ o 1 'modify x to content X1' | o 0 'add x with content X0' Differential Revision: https://phab.mercurial-scm.org/D6604

copies._filter() filters out copies whose source file does not exist in the start commit or whose target file does not exist in the end commit. We do that after chaining copies with dirstate copies or backward renames from another branch. We also do at the end of the changeset-centric copy tracing. The filtering means that we will remove copies to/from files that did not exist in some intermediate commit. That is inconsistent with what we do if a file has been deleted and then re-added (we allow updating across that). Copying the two first examples from issue6163: @ 4 'rename x to y' | o 3 'add x again' | o 2 'remove x' | | o 1 'modify x' |/ o 0 'add x' @ 4 'rename x to y' | o 3 'add x again' | | o 2 'modify x' | | | o 1 'add x' |/ o 0 'base' When doing `hg rebase -r 1 -d 4` in the first case, it succeeds, but `hg rebase -r 2 -d 4` in the second case does not. That's because we chain and filter via commit 0, which does not have file 'x' in the second case. IMO, that's clearly inconsistent. So this patch removes the filtering step so it only happens at the end. If a file was temporarily removed, whether via a merge base or not, it will now still be considered the same file. That fixes issue6163 for the changeset-centric case. Differential Revision: https://phab.mercurial-scm.org/D6603

I'd like to move the filtering of copies we do after chaining to the end of all chaining (in a single place in pathcopies()). One problem that came up when trying that was that we allow things like `hg cp -f <file> <existing file>` so the user can later amend that in. Filtering at the end would mean that we remove those copies. That would break `hg st -C`. This patch therefore moves the short-circuiting of dirstate copies into pathcopies() so we can more easily handle the dirstate-only case differently. I initially thought this might change some behavior when the user does `hg status --rev 'wdir()' --rev .` during an uncommitted merge, since _backwardrenames() would reverse the copies in that case. However, I couldn't come up with a test case where it made a difference. Differential Revision: https://phab.mercurial-scm.org/D6600

We had a test where the destination of a copy was removed and then added back. This patch adds similar cases where the break in history instead happens to the source file. There are three versions of this: 1. The break happens before the rename. 2. The break happens on a branch parallel to the rename (where copy tracing is done via the merge base) 3. The source is added on each side of the merge base. The break in history is thus in the form of a deletion when going backwards to the merge base and the re-add happens on the other branch. I've also added calls to `hg graft` in these cases to show the breakage in issue 6163. Another factor in these cases is matching nodeid (checked in copies._tracefile()). I've made two copies each of the cases to show the impact of that. One of these is the same as a test in test-rename-merge1.t, so I also deleted that test from there. Some of these tests currently fail, where "fail" is based on my current thinking of how things should work. I had initially thought that we should be more strict about not tracing copies across commits where the file did not exist, but issue 6163 made me reconsider. The only test case here that behaved differently in 4.9 is the exact case reported in issue 6163. Differential Revision: https://phab.mercurial-scm.org/D6599
