phabricator: warn if unable to amend, instead of aborting after posting...
phabricator: warn if unable to amend, instead of aborting after posting There was a divergence in behavior here between obsolete and strip based amending. I first noticed the abort when testing outside of the test harness, but then had trouble recreating it here after reverting the code changes. It turns out, strip based amend was successfully amending the public commit after it was posted! It looks like the protection is in the `commit --amend` command, not in the underlying code that it calls. I considered doing a preflight check and aborting. But the locks are only acquired at the end, if amending, and this is too large a section of code to be wrapped in a maybe-it's-held-or-not context manager for my tastes. Additionally, some people do post-push reviews, and amending is the default behavior, so they shouldn't see a misleading error message. The lack of a 'Differential Revision' entry in the commit message breaks a {phabreview} test, so it had to be partially conditionalized.

Error is handled reasonably. We override the phabtoken here so that
when you're developing changes to phabricator.py you can edit the
above config and have a real token in the test but not have to edit
this test.
$ hg phabread --config auth.hgphab.phabtoken=cli-notavalidtoken \
> --test-vcr "$VCR/phabread-conduit-error.json" D4480 | head
abort: Conduit Error (ERR-INVALID-AUTH): API token "cli-notavalidtoken" has the wrong length. API tokens should be 32 characters long.
Basic phabread:
$ hg phabread --test-vcr "$VCR/phabread-4480.json" D4480 | head
# HG changeset patch
exchangev2: start to implement pull with wire protocol v2
Wire protocol version 2 will take a substantially different
approach to exchange than version 1 (at least as far as pulling
is concerned).
This commit establishes a new exchangev2 module for holding
code related to exchange using wire protocol v2. I could have
added things to the existing exchange module. But it is already
phabupdate with an accept:
$ hg phabupdate --accept D4564 \
> -m 'I think I like where this is headed. Will read rest of series later.'\
> --test-vcr "$VCR/accept-4564.json"

The amend won't explode after posting a public commit. The local tag is left
behind to identify it.
$ echo 'public change' > beta
