Previously `hg phabsend` was imitating `hg email` and won't mutate
changesets. That works fine with reviewer-push workflow, reviewers run
`phabread`, `import`.
However, it does not work well with author-push workflow. Namely, the author
needs to run extra commands to get the right commit message, and remove the
local tag after push.
This patch solves those issues by adding the `--amend` option, so local
changesets will have the right commit message, and tags become unnecessary.
Test Plan:
Given the following DAG:
o 17
o 16
| o 15
| @ 14
|/
o 13
o 12
Run `hg phabsend '(13::)-17' --amend`, check the new DAG looks like:
o 21
| o 20
| @ 19
|/
o 18
| o 17
| x 16
| x 13
|/
o 12
And commit messages are updated to contain the `Differential Revision` lines.
Use `phabread` to make sure Phabricator has the amended node recorded.
Also check `phabsend .` followed by a `phabsend . --amend`, the commit
message will be updated and the tag will be removed.

This is a quick fix to make `hg phabread D189` work.
It seems we might want to replace all `r''` to `u''`, and add more
`encoding.*to*` to be more explicit when interacting with `json` module.

If you're shipping prerelease or rc packages using Munki, you'll
eventually discover that Munki's version comparison logic is not as
good as pip's. In theory we should be able to fix Munki, but it seems
entirely reasonable to produce version strings that sort reasonably
under these conditions. Since the requried logic not brief, add a new
script and some tests of that logic.
A followup change will wire this into the Makefile.
5ba3f753c9b1 introduced a use of 'hg revert --no-backup' which is
currently broken. Rather than try and do a fix on the (complicated)
revert code during the freeze, let's just give up on this test under
Python 3 until later. Once we do fix things, the test ratchet script
will re-enable it.
I used this to more quickly track down a failing test-check-config.t issue
in another repo. I thought it might be useful more generally, so I'm sending
it out in case others think it's a worthwhile change.
Previously, we trust Differential Revision in commit message blindly. This
patch adds sanity check so a host name change will be detected and the
commit message will be ignored.

The diff property contains metadata like "HG Node". Previously we skip
uploading a new diff if we are sure that the old patch and new patch have a
same content. That has issues when a pusher adds an obsmarker using the old
"HG Node" stored in the old diff.
This patch adds logic to update the diff property so "HG Node" gets updated
to prevent that issue.

This makes it more strict when checking whether or not we should update a
Differential Revision. For example,
a) Alice updates D1 to content 1.
b) Bob updates D1 to content 2.
c) Alice tries to update D1 to content 1.
Previously, `c)` will do nothing because `phabsend` detects the patch is not
changed. A more correct behavior is to override Bob's update here, hence the
patch.
This also makes it possible to return a reaonsable "last node" when there is
no tags but only `Differential Revision` commit messages.
Test Plan:
```
for i in A B C; do echo $i > $i; hg ci -m $i -A $i; done
hg phabsend 0::
# D40: created
# D41: created
# D42: created
echo 3 >> C; hg amend; hg phabsend .
# D42: updated
hg tag --local --hidden -r 2 -f D42
# move tag to the previous version
hg phabsend .
# D42: skipped (previously it would be "updated")
rm -rf .hg; hg init
hg phabread --stack D42 | hg import -
hg phabsend .
# D42: updated
hg tag --local --remove D42
hg commit --amend
hg phabsend .
# D42: updated (no new diff uploaded, previously it will upload a new diff)
```
The old diff object is now returned, which could be useful in the next
patch.

This adds a --confirm flag similar to the confirm flag of `hg email` using which
one can confirm the changesets before they get emailed. The confirm flag will
show the changesets and ask for confirmation before sending them.

For example, if "hg log" was defined as an alias:
# /etc/mercurial/hgrc
[alias]
log = log --graph
the buildrpm script would be surprised by log messages formatted in
unexpected ways, and bail out.
This patch sets HGPLAIN, effectively resetting all the user configs,
including log output, to a common state, making the build more
predictable across all the possible environments.
I'm not sure if there's a reason chg is not added by default.
If not, I would like to propose adding in this patch.

Sometimes people want to specify reviewer explicitly for a stack. The
webpage only allows changing reviewer for one revision at a time. This patch
adds a `--reviewer` flag to make it easier to specify reviewers.
Test Plan:
On a test Phabricator instance, enable `differential.allow-self-accept`,
assign myself as a reviewer and make sure it works. Also try an invalid
username and make sure it raises.

Previously we trust local tags blindly and that could cause wrong
Differential Revision to be updated, when people switch between Phabricator
instances.
This patch adds verification logic to detect such issue and remove
problematic tags. For example, a tag "D19" was on node "X", the code will
fetch all diffs attached to D19, and check if nodes server-side overlaps
with nodes in precursors. If they do not overlap, create a new Differential
Revision.
Test Plan:
Use a test Phabricator instance, send patches using `hg phabsend`, then
change the local tag manually to a wrong Differential Revision number.
Amend the patch and send again. Make sure the tag gets ignored and deleted.
Differential Revision: https://phab.mercurial-scm.org/D36
This allows us to do extra sanity checks using batch APIs to prevent
updating a wrong revision, which could happen when people switch Phabricator
instances and having stale tags living in the repo.

Previously we only respect hg:meta sent by phabsend. This patch makes it
respect local:commits sent by arc as well. This avoids issues where phabread
could lose the author information.
Test Plan:
Commit using a customized user, send the patch using arc to a test
Phabricator instance, and then read the patch using phabread. Make sure it
preserves the user information.

This was meant as a substitute for Python's "with" with multiple
context managers before we moved to Python 2.7. We're now on 2.7, so
we should have no reason to keep ctxmanager. "hg grep --all
ctxmanager" says that it was never used anyway.

When using the 'import' command running ZSH together with its
Mercurial-specific completions the flag '--partial' (introduced in Mercurial
3.1, 2014-08-01) is not offered as completion option.
This patch adds it to the list of completions for the 'import' command.
I'm still cleaning this up, but it's easier to do in bite-size chunks
like this than all at once. The negative lookahead avoids one false
positive category from some output related to finding Subversion
bindings.

It's possible to set up non-linear dependencies in Phabricator like:
o D4
|\
| o D3
| |
o | D2
|/
o D1
The old `phabread` code will print D1 twice. This patch adds de-duplication
to prevent that.
Test Plan:
Construct the above dependencies in a Phabricator test instance and make
sure the old code prints D1 twice while the new code won't.
Previously, we read Differential Revisions one by one by calling
`differential.query`.
Fetching them one by one is suboptimal. Unfortunately, there is no Conduit
API that allows us to get a stack of diffids using a single API call.
This patch tries to be smarter using a simple heuristic: when fetching D59
as a stack, previous IDs like D51, D52, D53, ..., D58 are likely belonging
to a same stack so just fetch them as well. Since `differential.query` only
returns cheap metadata without expensive diff content, it shouldn't be a big
problem for the server.
Using a test Phabricator instance, this patch reduces `phabread` reading a
10 patch stack from about 13 to 30 seconds to 8 seconds.
Previously, we call differential.getcommitmessage API to get commit
messages. Now we read that from "Differential Revision" object fetched
via "differential.query" API.
This removes one API call per patch.
This patch reworked phabread a bit so it fetches the lightweight
"Differential Revision" metadata for a stack first. Then read other data.
This allows the code to:
a) send 1 request to get all `hg:meta` data instead of N requests
b) patches are read in desired order, no need to buffer the output
"b)" reduces the memory usage from O(N^2) to O(N) since we no longer keep
old patch contents in memory.
The above `N` means the number of patches in the stack.
Previously we didn't abort. Now we abort if revs is empty. This is
consistent with "hg export" behavior. Maybe "return 1" is also a reasonable
behavior, but that's inconsistent with the existing "hg export".
Previously, `phabsend` uploads new diffs as long as the commit hash changes.
That's suboptimal because sometimes the diff is exactly the same as before,
the commit hash change is caused by a parent hash change, or commit message
change which do not affect diff content.
This patch adds a check examining actual diff contents to skip uploading new
diffs in that case.
The "hg:meta" property is for extra metadata to reconstruct the patch.
Previously it does not have node or parent information since I think by
reading the patch again, the commit message will be mangled (like, added the
"Differential Revision" line) and we cannot preserve the commit hash.
However, the "parent" information could be useful. It could be helpful to
locate the "base revision" so in case of a conflict applying the patch
directly, we might be able to use 3-way merge to resolve it correctly.
Note: "local:commits" is an existing "property" used by Phabricator that has
the node and parent information. However, it lacks of timezone information
and requires "author" and "authorEmail" to be separated. So we are using a
different "property" - "hg:meta" to be distinguished from "local:commits".
Previously, only tags can "associate" a changeset to a Differential
Revision. But the usual pattern (arc patch or hg phabread) is to put the
Differential Revision URL in commit message.
This patch makes the code read commit message to find associated
Differential Revision if associated tags are not found.
This makes some workflows possible. For example, if the author loses their
repo, or switch to another computer, they can continue download their own
patches from Phabricator and update them without needing to manually create
tags.
This patch adds a `phabread` command generating plain-text patches from
Phabricator, suitable for `hg import`. It respects `hg:meta` so user and
date information might be preserved. And it removes `Summary:` field name
which makes the commit message a bit tidier.
To support stacked diffs, a `--stack` flag was added to read dependent
patches recursively.
The `phabsend` command is intended to provide `hg email`-like experience -
sending a stack, setup dependency information and do not amend existing
changesets.
It uses differential.createrawdiff and differential.revision.edit Conduit
API to create or update a Differential Revision.
Local tags like `D123` are written indicating certain changesets were sent
to Phabricator. The `phabsend` command will use obsstore and tags
information to decide whether to update or create Differential Revisions.
The default Phabricator client arcanist is not friendly to send a stack of
changesets. It works better when a feature branch is reviewed as a single
review unit. However, we want multiple revisions per feature branch.
To be able to have an `hg email`-like UX to send and receive a stack of
commits easily, it seems we have to re-invent things. This patch adds
`phabricator.py` speaking Conduit API [1] in `contrib` as the first step.
This may also be an option for people who don't want to run PHP.
Config could be done in `hgrc` (instead of `arcrc` or `arcconfig`):
[phabricator]
# API token. Get it from https://phab.mercurial-scm.org/conduit/login/
token = cli-xxxxxxxxxxxxxxxxxxxxxxxxxxxx
url = https://phab.mercurial-scm.org/
# callsign is used by the next patch
callsign = HG
This patch only adds a single command: `debugcallconduit` to keep the patch
size small. To test it, having the above config, and run:
$ hg debugcallconduit diffusion.repository.search <<EOF
> {"constraints": {"callsigns": ["HG"]}}
> EOF
The result will be printed in prettified JSON format.
[1]: Conduit APIs are listed at https://phab.mercurial-scm.org/conduit/
The ignore regular expression has been updated to detect
"inconsistent config." If present, we track which configs have
that set and we suppress the conflicting defaults error for those
options.
I also added named groups to the regexp to aid readability.
A comment was added to profiling.py to make a desired inconsistent
value error go away.
For builds that run on hermetic environments, it's possible that the "less"
package is not installed by default, yet it's needed for tests to pass after
revision ca1519568a93 (which sets less as the fallback pager).
When trying to create a zstd bundle, the MSI based install said:
abort: compression engine zstd could not be loaded
The Inno installer is unaffected. The name will need to be updated to include
'cext' when merging into default.
