fix: ignore fixer tool configurations that are missing patterns
This is to prevent a crash under the same circumstances.
This is also to avoid data loss due to accidental application of a fixer tool
to all files, if the matching logic somehow changed to that effect. Affecting
all files until otherwise configured would be dangerous, and not very useful.
We shouldn't abort because there may be other fixers, and it may still be
useful to run them without having to adjust configuration. A user might not
feel confident in changing configs, for example.

py: error out if a "skip" character was given with non-dict to util.dirs()
util.dirs() keeps track of the directories in its input collection. If
a "skip" character is given to it, it will assume the input is a
dirstate map and it will skip entries that are in the given "skip"
state. I think this is used only for skipping removed entries ("r") in
the dirtate. The C implementation of util.dirs() errors out if it was
given a skip character and a non-dict was passed. The pure
implementation simply ignored the request skip state. Let's make it
easier to discover bugs here by erroring out in the pure
implementation too. Let's also switch to checking for the dict-ness,
to make the C implementation (since that's clearly been sufficient for
many years). This last change makes test-
issue660.t pass on py3 in
pure mode, since the old check was for existence of iteritems(), which

commit: improve the files field of changelog for merges
Currently, the files list of merge commits repeats all the deletions
(either actual deletions, or files that got renamed) that happened
between base and p2 of the merge. If p2 is the main branch, the list
can easily be much bigger than the change being merged.
This results in various problems worth improving:
- changelog is bigger than necessary
- `hg log directory` lists many unrelated merge commits, and `hg log
-v -r commit` frequently fills multiple screens worth of files
- it possibly slows down adjustlinkrev, by forcing it to read more
manifests, and that function can certainly be a bottleneck
- the server side of pulls can waste a lot of time simply opening the
filelogs for pointless files (the constant factors for opening even
a tiny filelog is apparently pretty bad)
So stop listing such files as described in the code. Impacted merge
commits and their descendants get a different hash than they would
have without this. This doesn't seem problematic, except for
convert. The previous commit helped with that in the hg->hg case (but
if you do svn->hg twice from scratch, hashes can still change).
The rest of the description is numbers. I don't have much to report,
because recreating the files list of existing repositories is not
easy:
- debugupgradeformat and bundle/unbundle don't recreate the list
- export/import tends to choke quickly applying patches or on
description that contain diffs,
- merge commits from the convert extension don't have the right files
list for reasons orthogonal to the current commit
- replaying the merge with hg update/hg merge/hg revert --all/hg
commit can end up failing in hg revert
- I wasn't sure that using debugsetparents + debugrebuilddirstate
would really build the right thing
I measured commit time before and after this change, in a case with no
files filtered out, several files filtered out (no difference) and 5k
files filtered out (+1% time).
Recreating the 100 more recent merges in a private repo, the
concatenated uncompressed files lists goes from 1.12MB to
0.52MB. Excluding 3 merges that are not representative, then the size
goes from 570k to 15k.
I converted part of mozilla-central, and observed file list shrinking
quite a bit too, starting at the very first merge,
733641d9feaf, going
from 550 files to 10 files (although they have relatively few merges,
so they probably wouldn't care).

convert: add a config option to help doing identity hg->hg conversion
I want to change the computation of the list of files modified by a
commit. In principle, this would simply change a cache. But since this
information is stored in commits rather than a cache, changing it
means changing commit hashes (going forward).
Some users rely on the convert extension from hg to hg not changing
hashes when nothing changes (usually). Allow these users to preserve
hashes despite changes to the changelog files computation by reusing
these files lists when the manifest is unchanged (since these files
list are derived from the manifest).

tests: show the files fields of changelogs for many merges
I don't think there's coverage for many of the subtle cases, and I
found it hard to understand what the code is doing by reading it. The
test takes 40s to run on a laptop, or 9s with --chg.
I have yet to find a description of what the files field is supposed
to be for merges. I thought it could be one of:
1. the files added/modified/removed relative to p1 (wouldn't seem
useful, but `hg diff -c -r mergerev` has this behavior)
2. the files with filelog nodes not in either parent (i.e., what is
needed to create a bundle out of a commit)
3. the files added/removed/modified files by merge itself [1]
It's clearly not 1, because file contents merges are symmetric. It's
clearly not 2 because removed files and exec bit changes are
listed. It's also not 3 but I think it's intended to be 3 and the
differences are bugs.
Assuming 3, the test shows that, for merges, the list of files both
overapproximates and underapproximates. All the cases involve file
changes not in the filelog but in the manifest (existence of file
at revision, exec bit and file vs symlink).
I didn't look at all underapproximations, but they looked minor. The
two overapproximations are problematic though because they both cause
potentially long lists of files when merging cleanly.
[1] even what it means for the merge commit itself to change a file is
not completely trivial. A file in the merge being the same as in one
of the parent is too lax as it would consider that merges change
nothing when they revert all the changes done on one side. The
criteria used in the test and in the next commit for "merge didn't
touch a file" is:
- the parents and the merge all have the same file
- or, one parent didn't touch the file and the other parent contains
the same file as the merge

phabricator: handle local:commits time being string or int
When setting local:commits arcanist has different behaviour depending on
whether the repo is git or hg. With hg it sets the time as a number, since it
calls PHP's strtotime on the value, but with git it sets it as a string.
Normally this wouldn't be an issue since phabread wouldn't be interacting with
Phabricator Revisions for git repos, but Mozilla has a secondary workflow for
git users that uses the git-cinnabar tool to interact with their hg repos. When
a git-cinnabar user uses the moz-phab tool to submit patches for mozilla-central
it makes use of Mozilla's fork of arcanist, which works with their local git
version of m-c, and thus sets the local:commit time as a string, and then
translates the commit hashes.
Currently when encountering such DREVS phabread dies with "TypeError: %d format:
a number is required, not str".
phabsend also used to set it as a string but wouldn't have encountered the
issue with its own DREVs since it would read hg:meta first.

continue: added logic for hg continue
This is part of GSoC19 project `Implement abort and
continue commands`. This patch is part of the continue plan.
This adds the basic logic for hg continue. This command
aborts an multistep operation like graft, histedit, rebase,
transplant and unshelve if they are in an unfinished state.
The first part of the logic is determining the unfinished
operation from the state detection API under statemod.
This API is extended to support hg continue by adding a method
to register the abort logic as a function (here continuefunc).
Once the unfinished operation is determined the registered
logic is used to resume the command in case it is interrupted.
The benefit of this kind of framework is that any new extension
developed can support hg continue by registering the command
and logic under statedetection API.
hg continue currently supports --dry-run/-n flag only.
It is used to dry run hg abort

rust: switch hg-core and hg-cpython to rust 2018 edition
Many interesting changes have happened in Rust since the Oxidation Plan was
introduced, like the 2018 edition and procedural macros:
- Opting in to the 2018 edition is a clear benefit in terms of future
proofing, new (nice to have) syntactical sugar notwithstanding. It
also has a new non-lexical, non-AST based borrow checker that has
fewer bugs(!) and allows us to write correct code that in some cases
would have been rejected by the old one.
- Procedural macros allow us to use the PyO3 crate which maintainers have
expressed the clear goal of compiling on stable, which would help in
code maintainability compared to rust-cpython.
In this patch are the following changes:
- Removing most `extern crate` uses
- Updating `use` clauses (`crate` keyword, nested `use`)
- Removing `mod.rs` in favor of an aptly named module file
Like discussed in the mailing list (
https://www.mercurial-scm.org/pipermail/mercurial-devel/2019-July/132316.html
), until Rust integration in Mercurial is considered to be out of the
experimental phase, the maximum version of Rust allowed is whatever the latest

py3: source-transform only call-sites of iteritems(), not definitions
branchmap.branchcache, among other classes, defines a
iteritems(). That currently gets replaced by items() by the source
transformer. That makes it harder for extensions to work with both py2
and py3, since they have to call either items() or iteritems() on
branchcache. Let's not replace definitions of iteritems() (and
itervalues()) and only replace the call-sites. We need to also add an
items() alias to branchcache (etc) so our transformer call-sites will
find it.

automation: correct the path separator in LIBPATH on Windows
I haven't tried building the x86 installer, but happened to notice this when
working on the thg installer. Experimenting in PowerShell seems to show that
LIBPATH was expanded at the end, but with ':' between, it effectively corrupted
`${root}\WinSDK\Lib` and the first path in LIBPATH.

abort: added support for merge
This adds support of `hg merge --abort` to `hg abort` plan.
This involves refactoring `hg.merge` into two different
functions removing the abort logic of `merge` from `hg.merge`
and then creating a seperate `hg.abortmerge` to handle the
abort logic so that the abortion of merge can be called
independently.
`hg.abortmerge` is then registered as `abortfunc` for the
state detection API so that `commands.abort` can use it to
deal with an unfinished merge operation.
Results are shown as tests.

This patch adds the support for shelve in `hg abort` plan.
For this the logic to load a `shelvedstate` and the error
handling for it had been shifted to a seperate function
`_loadunshelvedstate()`. This returns a tuple with `state` file
and `opts.`
`hgabortunshelve()` has been created for independent calls.
In case abortion of `unshelve` is called via `hg abort` the
`shelvedstate` needs to be loaded seperately. This has been
ensured by `_loadunshelvedstate()`
`hgabortunshelve()` is then registered as `abortfunc` for state
detection API.

copies: follow copies across merge base without source file (
issue6163)
As in the previous patch, consider these two histories:
@ 4 'rename x to y'
|
o 3 'add x again'
|
o 2 'remove x'
|
| o 1 'modify x'
|/
o 0 'add x'
@ 4 'rename x to y'
|
o 3 'add x again'
|
| o 2 'modify x'
| |
| o 1 'add x'
|/
o 0 'base'
We trace copies from the 'modify x' commit to commit 4 by going via
the merge base (commit 0). When tracing file 'y' (_tracefile()) in the
first case, we immediately find the rename from 'x'. We check to see
if 'x' exists in the merge base, which it does, so we consider it a
valid copy. In the second case, 'x' does not exist in the merge base,
so it's not considered a valid copy. As a workaround, this patch makes
it so we also attempt the check in mergecopies's base commit (commit 1
in the second case). That feels pretty ugly to me, but I don't have
any better ideas.
Note that we actually also check not only that the filename matches,
but also that the file's nodeid matches. I don't know why we do that,
but it was like that already before I rewrote mergecopies(). That
means that the rebase will still fail in cases like this (again, it
already failed before my rewrite):
@ 4 'rename x to y'
|
o 3 'add x again with content X2'
|
o 2 'remove x'
|
| o 1 'modify x to content X2'
|/
o 1 'modify x to content X1'
|
o 0 'add x with content X0'

copies: filter invalid copies only at end of pathcopies() (
issue6163)
copies._filter() filters out copies whose source file does not exist
in the start commit or whose target file does not exist in the end
commit. We do that after chaining copies with dirstate copies or
backward renames from another branch. We also do at the end of the
changeset-centric copy tracing. The filtering means that we will
remove copies to/from files that did not exist in some intermediate
commit. That is inconsistent with what we do if a file has been
deleted and then re-added (we allow updating across that).
Copying the two first examples from
issue6163:
@ 4 'rename x to y'
|
o 3 'add x again'
|
o 2 'remove x'
|
| o 1 'modify x'
|/
o 0 'add x'
@ 4 'rename x to y'
|
o 3 'add x again'
|
| o 2 'modify x'
| |
| o 1 'add x'
|/
o 0 'base'
When doing `hg rebase -r 1 -d 4` in the first case, it succeeds, but
`hg rebase -r 2 -d 4` in the second case does not. That's because we
chain and filter via commit 0, which does not have file 'x' in the
second case. IMO, that's clearly inconsistent. So this patch removes
the filtering step so it only happens at the end. If a file was
temporarily removed, whether via a merge base or not, it will now
still be considered the same file. That fixes
issue6163 for the
changeset-centric case.

copies: move short-circuiting of dirstate copies out of _forwardcopies()
I'd like to move the filtering of copies we do after chaining to the
end of all chaining (in a single place in pathcopies()). One problem
that came up when trying that was that we allow things like `hg cp -f
<file> <existing file>` so the user can later amend that in. Filtering
at the end would mean that we remove those copies. That would break
`hg st -C`. This patch therefore moves the short-circuiting of
dirstate copies into pathcopies() so we can more easily handle the
dirstate-only case differently.
I initially thought this might change some behavior when the user does
`hg status --rev 'wdir()' --rev .` during an uncommitted merge, since
_backwardrenames() would reverse the copies in that case. However, I
couldn't come up with a test case where it made a difference.

tests: add more tests of copy tracing with removed and re-added files
We had a test where the destination of a copy was removed and then
added back. This patch adds similar cases where the break in history
instead happens to the source file. There are three versions of this:
1. The break happens before the rename.
2. The break happens on a branch parallel to the rename (where copy
tracing is done via the merge base)
3. The source is added on each side of the merge base. The break in
history is thus in the form of a deletion when going backwards to
the merge base and the re-add happens on the other branch.
I've also added calls to `hg graft` in these cases to show the
breakage in issue 6163.
Another factor in these cases is matching nodeid (checked in
copies._tracefile()). I've made two copies each of the cases to show
the impact of that. One of these is the same as a test in
test-rename-merge1.t, so I also deleted that test from there.
Some of these tests currently fail, where "fail" is based on my
current thinking of how things should work. I had initially thought
that we should be more strict about not tracing copies across commits
where the file did not exist, but issue 6163 made me reconsider.
The only test case here that behaved differently in 4.9 is the
exact case reported in issue 6163.

abort: added logic for of hg abort
This is part of `GSoC19` project `Implement abort and
continue commands`. This patch is part of the `abort plan`.
This adds the basic logic for `hg abort`. This command
aborts an multistep operation like graft, histedit, rebase,
merge and unshelve if they are in an unfinished state.
The first part of the logic is determining the unfinished
operation from the state detection API under `statemod`.
This API is extended to support `hg abort` by adding a method
to register the abort logic as a function (here `abortfunc`).
Once the unfinished operation is determined the registered
logic is used to abort the command. The benefit of this kind
of framework is that any new extension developed can support
`hg abort` by registering the command and logic under
statedetection API.
`hg abort` currently supports `--dry-run/-n` flag only.
It is used to dry run `hg abort`
Further patches sequentially add support for `graft`, `rebase`,
`unshelve`, `histedit` and `merge`.

py3: don't run source transformer on hgext3rd (extensions)
It's unclear why the source transformer runs on hgext3rd. It's been
like that since it was introduced in
1c22400db72d (mercurial:
implement a source transforming module loader on Python 3,
2016-07-04), and that commit didn't say anything about it (but it says
that it doesn't have "support [...] for extensions").
I find that the current handling of hgext3rd just makes it harder to
convert extensions to Python 3. It makes you convert a bunch of
strings passed to getattr() and kwargs[] to r'' that could otherwise
have been left alone. It's also really confusing that the source
transformer runs when you import the extension as "extensions.foo=",
but not as "extension.foo=/some/path".
I suppose there is small number of (very simple) extensions that would
have worked without this patch that would now be broken. It seems okay
to me to break those.

filemerge: make last line of prompts <40 english chars (
issue6158)
I've chosen <40 as the target so that other languages that may have a 2x blowup
in character count can still have a chance to fit into an 80 column screen.
Previously, we would show a prompt like:
```
keep (l)ocal [dest], take (o)ther [source], or leave (u)nresolved for some/potentially/really/long/path?
```
On at least some systems, if readline was in use then the last line of the
prompt would be wrapped strangely if it couldn't fit entirely on one line. This
strange wrapping may be just a carriage return without a line feed, overwriting
the beginning of the line; example (100 columns wide, 65 character filename, and
yes there's 10 spaces on the end, I assume this is to handle the user inputting
longest word we provide as an option, "unresolved"):
```
ng/dir/name/that/does/not/work/well/with/readline/file.txt? ave (u)nresolved for some/lon
```
In some cases it may partially wrap onto the next line, but still be missing
earlier parts in the line, such as below (60 columns wide, 65 character
filename):
```
rev], or leave (u)nresolved for some/long/dir/name/that/do
s/not/work/well/with/readline/file.txt?
```
With this fix, this looks like this on a 60 column screen:
```
tool vim_with_markers (for pattern some/long/dir/name/that/d
oes/not/work/well/with/readline/file.txt) can't handle binar
y
tool meld can't handle binary
tool vim_with_markers can't handle binary
tool internal:merge3 can't handle binary

/well/with/readline/file.txt
file 'some/long/dir/name/that/does/not/work/well/with/readli

You can keep (l)ocal [working copy], take (o)ther [merge rev

posix: always seek to EOF when opening a file in append mode
Python 3 already does this, so skip it there.
Consider the program:
#include <stdio.h>
int main() {
FILE *f = fopen("narf", "w");
fprintf(f, "narf\n");
fclose(f);
f = fopen("narf", "a");
printf("%ld\n", ftell(f));
fprintf(f, "troz\n");
printf("%ld\n", ftell(f));
return 0;
}
on macOS, FreeBSD, and Linux with glibc, this program prints
5
10
but on musl libc (Alpine Linux and probably others) this prints
0
10
By my reading of
https://pubs.opengroup.org/onlinepubs/
009695399/functions/fopen.html
this is technically correct, specifically:
> Opening a file with append mode (a as the first character in the
> mode argument) shall cause all subsequent writes to the file to be
> forced to the then current end-of-file, regardless of intervening
> calls to fseek().
in other words, the file position doesn't really matter in append-mode
files, and we can't depend on it being at all meaningful unless we
perform a seek() before tell() after open(..., 'a'). Experimentally
after a .write() we can do a .tell() and it'll always be reasonable,
but I'm unclear from reading the specification if that's a smart thing
to rely on. This matches what we do on Windows and what Python 3 does
for free, so let's just be consistent. Thanks to Yuya for the idea.

update: fix spurious unclean status bug shown by previous commit
The crux of the problem is:
- the dirstate is corrupted (the sizes/dates are assigned to the wrong files)
- because when worker.worker is used with a return value (batchget in
merge.py here), the return value when worker.worker effectively parallelizes
is permuted
- this is because worker.worker's partition of input and combination of output
values are not inverses of one another: it split [1,2,3,4,5,6] into
[[1,3,5],[2,4,6]], but combines that into [1,3,5,2,4,6].
Given that worker.worker doesn't call its function argument on contiguous
chunks on the input arguments, sticking with lists means we'd need to
know the relation between the inputs of worker.worker function argument
(for instance, requiring that every input element is mapped to exactly
one output element). It seems better to instead switch return values to
dicts, which can combined reliably with a straighforward restriction.

getting all the copies for a changeset. This patch introduces such a
function. It uses it in the {file_copies} template to show that it
works. It relies on the existing scmutil.getrenamedfn() for caching in

copies: don't filter out copy targets created on other side of merge commit
If file X is copied to Y on one side of merge and the other side
creates Y (no copy), we would not mark that as copy. In the
changeset-centric pathcopies() version, that was done by checking if
the copy target existed on the other branch. Even though merge commits
are pretty uncommon, it still turned out to be too expensive to load
the manifest of the parents of merge commits. In a repo of
mozilla-unified converted to storing copies in changesets, about 2m30s
of `hg debugpathcopies FIREFOX_BETA_59_END FIREFOX_BETA_60_BASE` is
spent on this check of merge commits.
I tried to think of a way of storing more information in the
changesets in order to cheaply detect these cases, but I couldn't
think of a solution. So this patch simply removes those checks.
For reference, these extra copies are reported from the aforementioned
command after this patch:
browser/base/content/sanitize.js -> browser/modules/Sanitizer.jsm
testing/mozbase/mozprocess/tests/process_normal_finish_python.ini -> testing/mozbase/mozprocess/tests/process_normal_finish.ini
testing/mozbase/mozprocess/tests/process_waittimeout_python.ini -> testing/mozbase/mozprocess/tests/process_waittimeout.ini
testing/mozbase/mozprocess/tests/process_waittimeout_10s_python.ini -> testing/mozbase/mozprocess/tests/process_waittimeout_10s.ini
Since these copies were created on one side of some merge, it still
seems reasonable to include them, so I'm not even sure it's worse than
filelog pathcopies(), just different.

copies: do full filtering at end of _changesetforwardcopies()
As mentioned earlier, pathcopies() is very slow when copies are stored
in the changeset. Most of the cost comes from calling _chain() for
every changeset, which is slow because it needs to read manifests. It
needs to read manifests to be able to filter out copies that are were
created in one commit and then deleted. (It also filters out copies
that were created from a file that didn't exist in the starting
revision, but that's a fixed revision across calls to _chain(), so
it's much cheaper.)
This patch changes from _chainandfilter() to just _chain() in the main
loop in _changesetforwardcopies(). It instead removes copies that have
subsequently been removed by using ctx.filesremoved(). We thus rely on
that to be fast.
It timed this command in mozilla-unified:
hg debugpathcopies FIREFOX_59_0b3_BUILD2 FIREFOX_BETA_59_END
It took 18s before and 1.1s after. It's still faster when copy
information is stored in filelogs: 0.70s. It also still gets slow when
there are merge commits involved, because we read manifests there
too. We'll deal with that later.

revlog: add the option to track the expected compression upper bound
There are various optimization we can do if we can estimate the size of delta
before actually spending CPU compressing them. So we add a attributed dedicated
to tracking that.
We only use it on Manifest because (1) it structure is quite stable across all
Mercurial repository so its compression ratio is fairly universal. This is the
revlog with most extreme delta (cf the sparse-revlog optimization).
This will be put to use in later changesets.
Right now the compression upper bound is set to 10. This is a fairly
conservative value (observed value is more around 3), but I prefer to be safe
while introducing the optimization principles. We can tune the optimization
threshold later.

merge: fix race that could cause wrong size in dirstate
The problem is that hg merge/update/etc work the following way:
1. figure out what files to update
2. apply the update to disk
3. apply the update to in-memory dirstate
4. write dirstate
where step3 looks at the filesystem and assumes it sees the result of
step2. If a file is changed between step2 and step3, step3 will record
incorrect information in the dirstate.
I avoid this by passing the size step3 needs directly from step2, for
the common path (not implemented for change/delete conflicts for
instance).
I didn't fix the same race for the exec bit for now, because it's less
likely to be problematic and I had trouble due to the fact that the
dirstate stores the permissions differently from the manifest (st_mode
vs '' 'l' 'x'), in combination with tests that pretend that symlinks
are not supported.
However, I moved the lstat from step3 to step2, which should tighten
the race window markedly, both for the exec bit and for the mtime.

rust: new rust options in setup.py
The --rust global option turns on usage (and by default compilation)
of the rust-cpython based mercurial.rustext.
Similarly to what's previously done for zstd, there is a --no-rust
option for the build_ext subcommand in order not to build
mercurial.rustext, allowing for an OS distribution to prebuild it.
The HGWITHRUSTEXT environment variable is still honored, and has
the same effect as before, but now it works mostly by making
the --rust global option defaulting to True, with some special
cases for the direct-ffi case (see more about that below)
Coincidentally, the --rust flag can also be passed from the make
commands, like actually all global options, in the PURE variable
make local PURE=--rust
This feels inappropriate, though, and we should follow up with
a proper make variable for that case.
Although the direct-ffi bindings aren't directly useful any more, we
keep them at this stage because
- they provide a short prototyping path for experiments in which a C extension
module has to call into a Rust extension. The proper way of doing that would
be to use capsules, and it's best to wait for our pull request onto
rust-cpython for that: https://github.com/dgrunwald/rust-cpython/pull/169
- Build support for capsules defined in Rust will probably need to reuse
some of what's currently in use for direct-ffi.

rust: using policy.importrust from Python callers
This commit converts all current Python callers of
mercurial.rustext to the new policy.importrust system.
After this point, going through policy.importrust
or policy.importmod (in some more distant future)
is mandatory for callers of Rust code outside of
Python tests.
We felt it to be appropriate to keep Rust-specific tests
run inconditionally if the Rust extensions are present.
Georges Racinet <georges.racinet@octobus.net> [Wed, 29 May 2019 13:27:56 +0200] rev 42451
rust: module policy with importrust
We introduce two rust+c module policies and a new
`policy.importrust()` that makes use of them.
This simple approach provides runtime switching of
implementations, which is crucial for the performance
measurements such as those Octobus does with ASV.
It can also be useful for bug analysis.
It also has the advantage of making conditionals in
Rust callers more uniform, in particular
abstracting over specifics like `demandimport`
At this point, the build stays unchanged, with the rust-cpython based
`rustext` module being built if HGWITHRUSTEXT=cpython.
More transparency for the callers, i.e., just using
`policy.importmod` would be a much longer term and riskier
effort for the following reasons:
1. It would require to define common module boundaries
for the three or four cases (pure, c, rust+ext, cffi) and that
is premature with the Rust extension currently under heavy
development in areas that are outside the scope of the C extensions.
2. It would imply internal API changes that are not currently wished,
as the case of ancestors demonstrates.
3. The lack of data or property-like attributes (tp_member
and tp_getset) in current `rust-cpython` makes it impossible to
achieve direct transparent replacement of pure Python classes by
Rust extension code, meaning that the caller sometimes has to be able
to make adjustments or provide additional wrapping.

phabricator: add --blocker argument to phabsend to specify blocking reviewers
The way to signal to Conduit that a reviewer is considered blocking is just to
wrap their PHID in "blocking()" when including it in the list of PHIDs passed
to `reviewers.add`.
arc doesn't have a --blocker, instead one is supposed to append a '!' to the
end of reviewer names (I think reviewers are usually added in an editor rather
than the command line, where '!'s can be more hazardous).
moz-phab (Mozilla's arcanist wrapper) does have a --blocker argument, and being
explicit like this is also more discoverable. Even `arc diff`'s help doesn't
seem to mention the reviewer! syntax.
