tests: get access to thirdparty.cbor without requiring it to be installed This makes the test a noop when run from a tarball, but in return we can stop shipping a library we don't use. Differential Revision: https://phab.mercurial-scm.org/D5523

tests: add simplestorerepo to test-check-interfaces.py I'm not thrilled with this, but it'll help avoid future bitrot. Differential Revision: https://phab.mercurial-scm.org/D5521

simplestorerepo: migrate to in-hg CBOR code This is the only use of thirdparty.cbor outside of a test-* file, so it felt worthwhile to clean it up. Differential Revision: https://phab.mercurial-scm.org/D5520

simplestorerepo: minimal changes required to get this mostly working again I was going to change this code's use of CBOR to use our in-house CBOR code, but discovered it's been broken for a while. This messy change gets it back to a point where it mostly works, I think roughly as well as it ever did. Should we keep this and fix it up the rest of the way, or dump it in favor of the sqlite store? Would this be a good jumping-off point for some sort of union store that could facilitate a cleanup in remotefilelog? Differential Revision: https://phab.mercurial-scm.org/D5519

merge: make local file storage in the .hg/merge directory extensible This is similar to remotefilelog's 'getlocalkey' method, which must be overridden by systems which rely on full path names for access control purposes. Differential Revision: https://phab.mercurial-scm.org/D5534

context: schedule file prefetch before comparing for cleanliness When using a system like remotefilelog, we can occasionally run into scenarios where the local content cache does not have the data we need to perform these comparisons. These will be fetched on-demand, but individually; if the remotefilelog server isn't extremely low latency, the runtime of the command becomes dominated by the multiple getfile requests for individual files. By performing the prefetch, we can download these files in bulk, and save server resources and many network roundtrips. Differential Revision: https://phab.mercurial-scm.org/D5532

manifest: convert a recursive function to iterative one using stacks I am debugging a memory issue from yesterday where `hg update` goes upto taking 22GB of memory on our internal treemanifest repository. This is an interesting function and I saw memory consumption increasing while this function was running. It's sometimes hard to understand a recursive function and also the profile won't show you actual operations which took time, rather it will show you the function again and again in profile. I am yet to notice any memory consumption decrease with this patch, but I believe this will help like in making this a generator. Differential Revision: https://phab.mercurial-scm.org/D5413

obsutil: fix the issue5686 While traversing the obsolescence graph to find the successors sets of csets: In its 4th case (read comments of obsutil.successorssets to see all 4 cases) where we know successors sets of all direct successors of CURRENT, we were just missing a condition to filter out the case when a cset is pruned. And without this condition (that this patch added) it was making a whole successor set to [] just because of one pruned marker. For e.g:if following is the successors set of a cset A: A -> [a, b, c] if we prune c, we expect A's successors set to be [a, b] but you would get: A -> [] So this patch make sure that we calculate the right successorsset of csets considering the pruned cset (in split case).

histedit: add user input to warning message on editing tagged commits This is a follow-up patch to D5489. Now, the user will be able to input yes/no(default) on the warning message. Initially, it was the sleep of 1s and histedit window opens. Changes were made as suggested by @mharbison72 and @yuja. Differential Revision: https://phab.mercurial-scm.org/D5494

sparse: fix debugrebuilddirsate when narrow extension is enabled dirstate wrapping in narrow extension converts the manifest object to a list. So let's assume we get a list of files in sparse extension. Differential Revision: https://phab.mercurial-scm.org/D5481

tests: show that debugrebuilddirstate is broken with narrow+sparse This adds a test to show that debugrebuildirstate is broken when both narrow and sparse extensions are enabled. Differential Revision: https://phab.mercurial-scm.org/D5480

sparse: don't enable on clone if it was a narrow clone When both sparse and narrow extensions are enabled and we do a narrow clone, sparse enables itself because it reads --include flag and thinks that user is trying to do a sparse clone. This patch changes that behavior, and now if both extensions are enabled and user passes `--narrow`, then the includes and excludes won't be considered as part of sparse profile. Differential Revision: https://phab.mercurial-scm.org/D5479

tests: add tests for narrow clone when both sparse and narrow are enabled This patch adds tests for doing a narrow clone when client has both sparse and narrow enabled. As shown by this patch, we can see that the narrow clone has sparse enabled which we does not want here. Upcoming patch will fix this. Also while writing tests, I realized we don't have a flag to list the current sparse profile. Differential Revision: https://phab.mercurial-scm.org/D5478
