push-dests: move the code around missing default dest inside `get_push_paths` This function has a clear semantic and moving the code dealing with this inside it will help reduce duplication. Differential Revision: https://phab.mercurial-scm.org/D10385

push-dests: rework the handling of default value This new core is more straightforward and doing this early will make the next changeset simpler. Differential Revision: https://phab.mercurial-scm.org/D10384

outgoing: merge the code handling --graph with the main one The --graph code had its own copy of the logic. With the previous reorganisation of the code, we can now merge it with the main code, reducing fragile complication. As a side effect, `hg out --graph` now use the right return code when they are nothing outgoing. This explain the change to output in `tests/test-largefiles-misc.t`.

outgoing: move filtering logic in its own function This move code dedicated to a single purpose together and make the main code simpler. Right when we are getting ready to make it more complex :-D Differential Revision: https://phab.mercurial-scm.org/D10382

outgoing: make `recurse` a real function If we want to use this in a loop, we need to be able to pass argument. Differential Revision: https://phab.mercurial-scm.org/D10381

outgoing: remove some early return Since 066b8d8f75b8, the push command accept multiple destination. However `hg outgoing` does not. On the way to fix this, we need to clean up the outgoing code. We start with removing some early return to make the code ready to house more changes. Differential Revision: https://phab.mercurial-scm.org/D10380

infinitepush: use the new function to determine push destination Since 066b8d8f75b8, the push command accept multiple destination. `infinitepush` was not aware of that. We now use the new `urlutil.get_push_paths` function to determine the push destination, fixing the issue. This will also make future evolution of that logic transparent for infinitepush We still disallow push to multiple destinations if infinite push is enabled because I don't know what this means for infinite push. However user will now get a clear error message instead of a crash. Differential Revision: https://phab.mercurial-scm.org/D10379

urlutil: add a `get_pull_paths` to perform the pull destination logic As is this changeset does not change anything. However having an official empty point will help unifying the logic and encapsulate the details and update the logic to support path definition pointing to multiple other path.

urlutil: extract `parseurl` from `hg` into the new module The new module is well fitting for this new code. And this will be useful to make the gathered code collaborate more later. Differential Revision: https://phab.mercurial-scm.org/D10375
