help: clarify when `$HG_URL` and `$HG_SOURCE` are added in hooks Differential Revision: https://phab.mercurial-scm.org/D10400

nodemap: deal with data mmap error If the file is too small, the mmapread call would raise a ValueError. We catch that and ignore nodemap content (as we do without mmap). This make the repository slightly slower (until the next write) but usable. Unlike the current crash. Differential Revision: https://phab.mercurial-scm.org/D10458

nodemap: test various corruption scenario for the persistent nodemap Corruption can happens in the wild, either because some of our code is buggy or because repository were shared/transfered in a strange manners. Currently one of the corruption case (not enough data) lead to a crash. We add explicit tests for theses cases. Differential Revision: https://phab.mercurial-scm.org/D10457

cmdutil: fix an uninitialize variable usage in clearunfinished() I happened to notice that PyCharm flagged this while looking for something else. I'm pretty sure it meant to check the current state in the iteration, and not keep reusing the last one in the previous iteration. Differential Revision: https://phab.mercurial-scm.org/D10459

help: prepend environment variables used in hooks with "$" Most of them have "$" prefix but some don't, so adding it for consistency. Differential Revision: https://phab.mercurial-scm.org/D10398

revset: drop an outdated comment There is not `ui.expandpath` call there anymore. Differential Revision: https://phab.mercurial-scm.org/D10435

ui: deprecated `ui.expandpath` This function return a single path, something incompatible with the coming change to `[paths]` definition to allow multiple associated urls. Now that all user got migrated, we deprecate the function. Differential Revision: https://phab.mercurial-scm.org/D10432

urlutil: remove usage of `ui.expandpath` in `get_clone_path` We want to deprecate `ui.expandpath` and simplify the code before adding more complexity in the form of `[paths]` entry pointing to multiple url. So we inline the relevant bits. Differential Revision: https://phab.mercurial-scm.org/D10431

urlutil: remove usage of `ui.expandpath` in `get_unique_pull_path` We want to deprecate `ui.expandpath` and simplify the code before adding more complexity in the form of `[paths]` entry pointing to multiple url. So we inline the relevant bits. Differential Revision: https://phab.mercurial-scm.org/D10430

urlutil: remove usage of `ui.expandpath` in `get_pull_paths` We want to deprecate `ui.expandpath` and simplify the code before adding more complexity in the form of `[paths]` entry pointing to multiple url. So we inline the relevant bits. Differential Revision: https://phab.mercurial-scm.org/D10429

debugbackupbundle: use `get_unique_pull_path` This is the last known user of `ui.expandpath` outside of `urlutil`. Hooray. Differential Revision: https://phab.mercurial-scm.org/D10428

debugssl: use `get_unique_pull_path` Let's move this code to the new API. Differential Revision: https://phab.mercurial-scm.org/D10427

debugdiscovery: use `get_unique_pull_path` Lets move this code to the new API. Differential Revision: https://phab.mercurial-scm.org/D10426

profiling: use `util.expandpath` instead of `ui.expandpath` for output Given we are talking about the path to an output file, I am fairly certain that the initial author meant to expand `~` and the like and not to resolve entry from `[paths]`. Differential Revision: https://phab.mercurial-scm.org/D10425

dispatch: use the new API to resolve --repository An even weirder feature of Mercurial is the ability to use `[paths]` alias as value of `--repository`. The weird feature now use the new APIs. Differential Revision: https://phab.mercurial-scm.org/D10424

revset: use `get_unique_pull_path` for `remote(…)` This one is also resolving path. For now we restrict the feature to a single destination. This might change in the future. Differential Revision: https://phab.mercurial-scm.org/D10422

remotefilelog: use `get_unique_pull_path` in `getflogheads` Another command moved to the new API, hooray. Differential Revision: https://phab.mercurial-scm.org/D10421

summary: use the new APIs Summary can perform some incoming/outgoing queries (that should be common to the other command with the same needs, but that is another story). We now use the new APIs to do so. The current code behavior is a bit fishy, relying to the fact "default" will be picked as the destination in last resort. I did not altered that, but left various comment to highlight the issue. Differential Revision: https://phab.mercurial-scm.org/D10420

share: use `get_clone_path` Since `hg share` is mostly like clone, do the same changes there. Differential Revision: https://phab.mercurial-scm.org/D10419

init: use `get_clone_path` when suitable `hg init` has this weird feature were you can refer to `[paths]` entry select the path to initialize. We move that code to the new APIs. Differential Revision: https://phab.mercurial-scm.org/D10418

clone: use `get_clone_path` "Surprisingly", the new API is well suited for `hg clone` too. Differential Revision: https://phab.mercurial-scm.org/D10417

incoming: kill the `repo._subtoppath =` hack We do the same as for `hg outgoing`, instead of relying on implicit passing value by monkey punching them onto the repo object, we pass equivalent information by argument to the proper function. This is way cleaner. Differential Revision: https://phab.mercurial-scm.org/D10416

identify: use `get_unique_pull_path` The command only support a single destination. We use the associated API. Differential Revision: https://phab.mercurial-scm.org/D10415

bundle: support multiple destinations `hg outgoing` and `hg push` now support multiple destination. We do the same for `hg bundle`. Various other commands needs this kind of behavior and it would be create to factor this code out for their usage. However this is an adventure for another time. They are some minor change to the tests (in addition to the new test for the feature): * one because I updated a message to plurals, * another one because the error changed, and I actually find it clearer. Differential Revision: https://phab.mercurial-scm.org/D10414

lfs: use the new APIs The part of the lfs store that requires a destination cannot operate on multiple destination (yet). So we move them to the dedicated APIs. Differential Revision: https://phab.mercurial-scm.org/D10413

fastannotate: use `get_unique_pull_path` The code does not support multiple destination yet, so lets move it to the dedicated API. Differential Revision: https://phab.mercurial-scm.org/D10412

remotefilelog: use the right expandpath in to expand `~` Given the context where path is most likely a file system path, I suspect that the initial author confused ui.expandpath and util.expandpath (a proxy for os.path.expanduser and co) Differential Revision: https://phab.mercurial-scm.org/D10411

transplant: use `get_unique_pull_path` The command does not support multiple destination (yet). Differential Revision: https://phab.mercurial-scm.org/D10410

infinitepush: use `get_unique_pull_path` The extension does not support multiple destination (yet). Differential Revision: https://phab.mercurial-scm.org/D10456

relink: use `get_unique_pull_path` The code does not support multiple destination and will probably never do so. So lets use the dedicated API for this case. Differential Revision: https://phab.mercurial-scm.org/D10409

histedit: use `get_unique_push_path` Same as for `pathbomb`, this code does not support multiple destinations yet. It might in the future, probably with code put in common with patchwork, but for now lets use the dedicated API. Differential Revision: https://phab.mercurial-scm.org/D10408
