I'm not sure if the test is actually needed, so feel free to drop it/ask me to.

You should probably run hg mv -A hgext/shelve.py mercurial/shelve.py and amend and re-send to preserve history.

Is it worth adding a test using histedit, or is the use in existing tests enough?

Doctor repo name in the recordings that I'd missed before

While the .t test can't directly show this, now that we have a VCR matcher for the body we can test the output. In action: https://phabricator-dev.allizom.org/D1253

Switch to comparing sets.

@mharbison72 thanks for tips on adding test. Will add tests in next iteration.
I found that Differentials do have a branch field, maybe we can use that? https://secure.phabricator.com/source/phabricator/browse/master/src/applications/differential/customfield/DifferentialBranchField.php

Seems worth a shot. I don’t know anything about it, but presumably this would be rendered specially in the web UI, like the test plan, etc. That sounds better than as a follow up comment. It also seems natural enough that maybe it can be done unconditionally, instead of needing the argument.

Yeah, it shows in the Diff Detail pane, like here. Unfortunately I think it can be only set when using the creatediff endpoint, which is what I had to change my fork to do (though I could be wrong, the conduit docs are too sparse to be sure).

Last night I tried different endpoints and looks like creatediff is the only one which can be used to set the branch. I have asked on their discourse https://discourse.phabricator-community.org/t/conduit-api-to-set-branch-of-a-differential/2521.
Talking about creatediff, can it be used instead of createrawdiff? It it's possible can you paste the changes you did your fork, maybe we need the exact same changes.

Make compatible with Py3.5, separate comments about json functions so they are more readable.

Switch to using pycompat.byteskwargs.

It's probably better to apply iterbytestr() to view[pos:] so ch is
always a byte string.

pycompat.byteskwargs() can be used instead.

Perhaps, the input data has to be converted to unicode. IIRC old Python 3
versions don't accept bytes.

Ah, yeah you're right, it only started accepting bytes in 3.6.

Maybe we can use templatefilters.json() to dump internal (i.e. no unicode)
dict.

Ah, we can indeed (thanks for the pointer), with one caveat: the formatting.
The existing output is nicely formatted for human readability, with each entry on a new line and indented appropriately. templatefilters.json() isn't capable of that.
Do we mind losing that? It's also tested for in test-phabricator.t. Compare before:

{
  "cursor": {
    "after": null,
    "before": null,
    "limit": 100,
    "order": null
  },
  "data": [],
  "maps": {},
  "query": {
    "queryKey": null
  }
}

After:

{"cursor": {"after": null, "before": null, "limit": 100, "order": null}, "data": [], "maps": {}, "query": {"queryKey": null}}
