Add a linter to identify the use of product name literals in "pht()" text.
The linter could fix these automatically, but it looks like there are fewer than 200 across both Arcanist and Phabricator and some sampling suggests that many are probably clearer when rewritten into generic language anyway.

In the update to D21716 the `str_starts_with` function was added which is only available in PHP 8. This changes it to use `strncmp()` which is compatible back to PHP 4.
Additionally fixed running into an error when trying to run `arc amend` on a commit which already matches the content known in Phabricator. Mercurial throws an error when running `amend` without file changes and using the exact same commit message it already has.
Test Plan:
I created a commit and revision then used `hg amend -e` to modify the commit message locally.
I used `arc amend` to update the commit message back to the appropriate message from Phabricator.
I ran `arc amend` again to verify that the command did not fail even though the commit message is unchanged.
I ran `arc inspect --explore -- 'commit(674492bb460)'` and verified it matched the appropriate commit, to verify the substring matching works properly.

Summary:
Ref T13666. Currently, "PhabricatorRepository->newConduitFuture()" sometimes returns a real "ConduitFuture" (when repository clustering is configured) and sometimes returns a degenerate "ImmediateFuture" (when repository clustering is not configured).
To populate the "ImmediateFuture", the Conduit method is called inline without any special exception handling. This means that the two pathways have significantly different exception behavior:
- On the "ImmediateFuture" pathway, the "newConduitFuture()" method itself may raise an exception related to resolving the call (e.g., invalid parameters).
- On the "ConduitFuture" pathway, exceptions are raised only once the future is "resolve()"'d.
The second behavior is the correct behavior (and the primary behavior of upstream test environments, since all my stuff and the Phacility stuff is clustered).
Prepare to put both pathways on the second behavior by introducing a "MethodCallFuture", which can move the `$conduit_call->execute()` call (and thus its exception handling) to future resolution time.
See also the followup diff in Phabricator to actually enact this change.

`arc liberate` has been broken for a while because the `log` function attempts to call `fwrite` (whose third argument is an integer length) instead of `fprintf`. I think maybe PHP 5 was more lenient about this? Anyway, this bug makes other development somewhat tricky.
The arcanist source in general seems to be split between `fwrite(STDERR, $message."\n")` and `fprintf(STDERR, "%\n", $message)`; I decided to go with the latter.
This is sort of a test balloon on submitting diffs to Phorge. Please feel free to let me know if there's anything you'd like done differently!

Summary:
Currently there are a number of `--config extensions.blah=` sprinkled throughout the Mercurial APIs which aren't pleasant to look at. Additionally it turns out the `rebase` command requires the `rebase` extension which is not turned on by default. Uses of `rebase` should also be including this flag to enable the extension when it's in use.
This adds `ArcanistMercurialAPI::buildMercurialExtensionCommand()` which allows running a Mercurial command that requires an extension just by naming the extension instead of providing the full `--config..` argument.
It can be used e.g.
```lang=php
$api->execxLocalWithExtension(
'strip',
'strip --rev %s --',
$rev);
$api->execxLocalWithExtension(
'arc-hg',
'arc-amend --logfile %s',
$tmp_file);
```
Which produces
```lang=console
$ hg --encoding utf-8 --config 'extensions.strip=' strip --rev 82567759e2d703e1e0497f5f41363de3a1500188 --

I also ran `arc land --onto-remote default` while `arc-hg.py` raised an exception for the "remote" case and verified that the error was caught by Arcanist and displayed the error and prevented further execution. I removed the error from `arc-hg.py` and re-ran the command and verified it succeeded.

Summary:
After `arc diff` creates a revision in Phabricator it amends the commit to include a link to the revision in the commit message. For Mercurial this is done with `hg commit --amend --logfile` however this will fail when trying to create a diff for a non-head commit.
This updates `ArcanistMercurialAPI::amendCommit()` to allow amending a non-head commit in two ways, depending on whether `evolve` is in use:
No evolve:
1. Rebasing the current commit onto the current commit's parent, using the new commit message
2. Rebasing all children + descendants of the current commit onto the new resulting commit
3. Stripping the original commit
With evolve:
1. Amend the commit with `hg amend --logfile`
2. Run `hg evolve` to tidy up all commits
Test Plan:
I created 6 commits in a row placing a bookmark at commits 2 `bookmark1`, 4 `bookmark2`, and 6 `bookmark3`, and ensured I had `arc:bookmark` in my base ruleset.
No evolve, non-head changeset:
1. I verified I did not have `evolve` enabled by running `hg debugextensions` and did not see `evolve` in the listed active extensions.
2. I updated to `bookmark1` and modified a file to leave a dirty working state.
3. I ran `arc diff` and when prompted to amend my changes I said "yes", and verified a phab revision was created properly.
4. I checked the status of my repository and verified it was still linear and the bookmarks pointed to the proper commits.
5. I ran `hg log -r bookmark1 --template {desc}` to view the full commit message and verified it contained both `Summary: ...` and `Differential Revision: https://...`.
6. I ran `hg diff -c bookmark1` and verified the changes for that commit included the changes I made in step 2.
No evolve, head changeset:
1. I updated to `bookmark3` which is the head commit and modified a file to leave a dirty working state.
2. I ran `arc diff` and when prompted to amend my changes I said "yes", and verified a phab revision was created properly.
3. I checked the status of my repository and verified it was still linear and all the bookmarks pointed to the proper commits.
4. I ran `hg log -r bookmark3 --template {desc}` to view the full commit message and verified it contained both `Summary: ...` and `Differential Revision: https://...`.
5. I ran `hg diff -c bookmar3` and verified the changes for that commit included the changes I made in step 1.
With evolve:
1. I enabled `evolve` and verified it was enabled by running `hg debugextensions` and saw `evolve` in the listed active extensions.
2. I updated to `bookmark2` and modified a file to leave a dirty working state.
3. I ran `arc diff` and when prompted to amend my changes I said "yes", and verified a phab revision was created properly.

Summary:
Refs T13546
**Behavior Changes**
1. Currently, after landing the `--onto` bookmark will not be advanced to the newly pushed commit(s)
- This updates so that after pushing commits upstream, onto-marker bookmarks are pulled back from the server to retrieve their updated state
2. Currently, after landing the working directory will typically be the old `--onto` commit
- This updates the behavior in the following ways
1. If the starting working state is a commit that is part of a revision being landed, the post-land state will be the newly published commit for that revision
2. If the starting working state is a commit for a tip revision being landed and there is only a single `--onto` target, the post-land state will be the newly published commit and the `--onto` bookmark will be activated, if applicable. If there are multiple `--onto` targets defined (uncommon) then the resulting working state will be the same behavior as before, as the desired behavior for this case is ambiguous.
3. If the starting working state is a commit that is not part of any revision being landed, then the post-land state will be that same commit, activating the same previous bookmark if applicable.
**Bugs Fixed**
1. When landing a diff that includes multiple commits, where the non-tip commit adds a file and later commit modifies that file, the land process would fail during rebasing.
2. When landing, the display of what commits are going to be landed only includes the commit hash but should include part of the commit message for easy identification.
3. If errors occur during a rebase while landing, the resulting state is an in-progress rebase. Users will typically not be able to resolve this in-progress rebase and possibly confuse them further as they have to first abort the rebase before trying to clean up. These rebases will now be aborted by arcanist before exiting.
4. If using evolve, landing a non-tip revision would leave behind orphaned commits.
Test Plan:
Bookmark test
- I created a diff with bookmark `test`, as a branch from before the `master` commit
- I updated working state to activate `test`
- I landed that diff
- I verified that the resulting working state was on the newly published `master` commit
Non-bookmark test
- I created a diff with bookmark `test`, as a branch from before the `master` commit
- I updated working state to be the new commit, but not activate `test` even though it points to that same commit
- I landed that diff
- I verified that the resulting working state was on the newly published `master` commit
Not-working state test
- I created a diff with bookmark `test`, as a branch from before the `master` commit
- I updated working state to an older commit not related to the one being landed
- I landed that diff
- I verified the ending resulting working state was on the older commit I was on prior to landing
Multiple commits test
- Using `test` bookmark I created a commit that added a new file, made a diff, made another new commit on top of it which modified that file, then updated the diff
- I updated my working state to the first commit for the diff (non-head)
- I ran `arc land test` to land the diff
- I verified that the resulting working state was on the newly published `master` commit
Landing while on `master`
- I created a diff with a bookmark `test`, as a branch from before the `master` commit
- I updated working state to the `master` bookmark
- I landed that diff
- I verified that the resulting working state was on the newly published `master` commit
Landing with no local `master` bookmark
- I created a diff consisting of two commits with bookmark `test`, as a branch from before the `master` commit
- I left working state on `test` and deleted my local `master` bookmark
- I landed that diff
- I verified that the resulting working state was on the newly published `master` commit and the `master` bookmark was pulled and active
Cascading diffs while on an earlier diff changeset
- I setup two diffs, each consisting of two commits, one depending on the other
- I put the working state onto a commit from the earlier diff
- I landed the later diff
- I verified that the resulting working state was on the newly published commit associated with the earlier diff, which is not the new `master` commit so there was no active bookmark
Cascading diffs while on the later diff changeset
- I setup two diffs, each consisting of two commits, one depending on the other
- I put the working state into a commit from the later diff
- I landed the later diff
- I verified that the resulting working state was on the newly published commit for the later diff which was `master` and `master` was active
Landing a non-tip revision, with evolve
- I setup three diffs, each consisting of two commits, creating a dependency chain
- I verified I had the evolve extension enabled via `hg debugextensions`
- I put the working state on a commit in the first revision
- I landed the second revision
- I verified that the resulting working state was clean, that revisions 1 and 2 were properly landed and published, and the resulting working state was on the published commit for the first revision.
Landing a non-tip revision, without evolve
- I setup three diffs, each consisting of two commits, creating a dependency chain
- I verified I did not have the evolve extension enabled via `hg debugextensions`
- I put the working state on a commit in the first revision
- I landed the second revision
- I verified that the resulting working state was clean, that revisions 1 and 2 were properly landed and published, and the resulting working state was on the published commit for the first revision.

Summary:
When non-ascii characters appear in revision titles/summaries the `patch` and `diff` (to update) commands will fail on Windows systems. This often occurs due to “smart quotes” or "em—dash" characters being inserted into commit messages by editors on "user-friendly" operating systems like macOS.
This can be worked around by forcing all mercurial commands to use the global option `--encoding utf-8` which applies for any mercurial command. This option was [[ https://www.mercurial-scm.org/repo/hg/rev/a88e02081a88 | added in ~2006 ]] so this should work across all supported versions of mercurial.
Refs T13649
Test Plan:
I created a diff on a mercurial repository using smart quotes in the "Title" and "Summary" fields as well as in the content of a file being changed. Then on macOS, Windows (PowerShell), and Windows (cmd.exe) I was able to `patch` down the revision, make a modification, and `diff` the change back up to Phabricator, as well as `land` the change. I verified the commit and content looked correct on macOS as well as on Windows by using `nvim` which seems to properly detect and render the encoding, whereas mercurial displays the smart quotes and em-dashes with odd characters instead.
I did a grep through Arcanist codebase to find other places where `--encoding` might be specified for mercurial commands and could not find any. In the event that somehow this argument is added elsewhere I verified that multiple specifications of `--encoding utf-8` does not cause any issues and the later specification of `--encoding` appears to "win".
```lang=console
$ hg --encoding utf-8 --encoding utf-8 log -r tip
# prints out results in UTF-8 without issue
$ hg --encoding utf-8 log --encoding latin-1 -r tip
# prints out results in latin-1 without issue

Summary:
Ref T13576. See that task for discussion.
When a user runs `arc land --pick A`, they may be selecting a range of commits ("X..Y") which have ancestors ("V..W") that should NOT land.
We must slice "X..Y" out of history before we can merge it, to avoid landing changes from "V..W".
When "X..Y" is simple and linear, we can rebase the range to pick our desired slice out of history.
When "X..Y" includes merge commits, we frequently can not, and I could not identify any simple alternative. The best alternative I came up with is this "reduce" operation:
- squash "into" onto Y, producing S, to guarantee there are no natural conflicts;
- squash S onto X^, producing T, to get rid of the merge commits;
- rebase T onto "into", producing R, to slice "X..Y" out of history;
- squash R onto "into", producing Q. (R and Q will be the same, but this simplies the code.)
This feels flimsy and fragile, but I can't immediately find a way to break it. See T13576 for more discussion.
Test Plan:
- Applied conflicting changes to `example.txt` in `master` and `feature1`.
- Ran `arc land`, got a merge conflict.
- Resolved the conflict with `git merge master`.
- Ran `arc land`.
- Before: merge conflict.
- After: `arc land` resolves the merge correctly.
- Stacked `feature2` on `feature1`, and made various mutations to `feature1` and `feature2`, then ran `arc land --pick feature2`. Changes made in `feature1` should not land, and they mostly do not. See T13576.

Summary:
PHP 8's sprintf raises a ValueError when encountering unknown format
specifiers (previously it would eat the argument and print nothing), so
linting format strings like %Ls dies with an uncaught ValueError.
Fix this by using a custom callback during linting to turn all format
specifiers into %s and replace the dummy null argument with the original
format specifier, ensuring we always end up providing valid input to the
sprintf at the end. This has the nice property that the output of the
call to xsprintf is the original format string, though any
transformation into valid input would do.

Summary:
See PHI1808. Currently, "arc land <some bookmark>" does not destroy the bookmark in Mercurial. There are three issues here:
- "hg rebase --keep --collapse" moves bookmarks to the rewritten commits;
- "hg strip" moves bookmarks backwards;
- "hg prune" moves bookmarks backwards.
To get around "hg rebase", save and restore bookmark state.
To get around "hg strip" and "hg prune", explicitly destroy bookmarks pointing at commits before we strip/prune those commits.
Test Plan:
- Ran "arc land <some bookmark> --trace". Saw arc reset the bookmark position after rebasing, and destroy the bookmark explicitly before stripping.
- When the workflow exited, saw no more bookmark (previously: bookmark existed and pointed at a possibly-intermediate state).

Summary:
Ref PHI1808. In Mercurial, we must save and restore bookmark state explicitly.
- Save and restore bookmarks.
- Clean up concepts in "arc-ls-markers" slightly, so we don't need separate "isCurrent" and "isActive" flags, hopefully.
I believe the totality of Mercurial state is:
- A (non-bare) working copy points at exactly one commit (which might be the empty/null commit, in an empty repository).
- A working copy has exactly one active branch.
- Each branch has zero or more heads.
- Each head may be closed.
- Each (non-null) commit belongs to exactly one branch.
- Note that the active branch may have zero heads and zero commits which belong to it!
- A working copy has zero or one active bookmark.
To capture this, we now emit:
- A list of branch heads. If a branch head is a working copy commit, that head is flagged as active.
- A list of bookmarks. If a bookmark is the current bookmark, that bookmark is flagged as active.
- A single "branch-state" virtual marker. This covers the case where you have run "hg branch X" to create X, but no objects in the working copy actually correspond to X yet. It also covers the case where you are on a concrete branch, but not any head of that branch.
- A single "commit-state" virtual marker. This always shows the current commit in the working copy.
Test Plan:
- Useful states to test are:
- Empty repository (not all commands currently work here).
- Normal repository, on a bookmark.
- Normal repository, no bookmark.
- "hg up 123" to update to somewhere in history.
- "hg branch X", to start a new branch with no commits.
- Ran "arc branches" and "arc bookmarks" in various states. Saw generally sensible output.

Summary:
See PHI1802. Currently, we can't raise a "you must login" error in a generic way at the beginning of a workflow because we don't know if a workflow needs credentials or not.
For example, "arc help" does not need credentials but "arc diff" does.
Additionally, some actual Conduit calls do not need credentials ("conduit.ping", "conduit.getcapabilities") and others do.
Although I'd like to simplify this eventually and move away from anonymous/unauthenticated "arc", this isn't trivial today. It's also possible for third-party code to add authenticated calls to "arc help", etc., so even if we could execute these tests upfront it's not obvious we'd want to.
So, for now, we raise "you must login" at runtime, when we receive an authentication error from Conduit.
This got implemented for Toolsets in a well-intentioned but not-so-great way somewhere in wilds/experimental, with an "ArcanistConduitCall" that behaves a bit like a future but is not really a future. This implementation made more sense when ConduitEngine was serving as a future engine, and FutureProxy could not rewrite exceptions.
After the Toolsets code was first written, ConduitEngine has stopped serving as a future engine (this is now in "HardpointEngine"). Since HardpointEngine needs a real future, this "show the user a login message" code gets bypassed. This results in user-visible raw authentication exceptions on some workflows:
```
[2020-06-30 21:39:53] EXCEPTION: (ConduitClientException) ERR-INVALID-SESSION: Session key is not present. at [<arcanist>/src/conduit/ConduitFuture.php:76]
```
To fix this:
- Allow FutureProxy to rewrite exceptions (see D21383).
- Implement "ArcanistConduitCall" as a FutureProxy, not a future-like object.
- Collapse the mixed-mode future/not-quite-a-future APIs into a single "real future" API.
Test Plan:
- Created a paste with "echo hi | arc paste --".
- Uploaded a file with "arc upload".
- Called a raw method with "echo {} | arc call-conduit conduit.ping --".
- Invoked hardpoint behavior with "arc branches".
- Grepped for calls to either "resolveCall()" method, found none.
- Grepped for calls to "newCall()", found none.
- Grepped for "ArcanistConduitCall", found no references.
Then:
- Removed my "~/.arcrc", ran "arc land", got a sensible and human-readable (but currently ugly) exception instead of a raw authentication stack trace.
Differential Revision: https://secure.phabricator.com/D21384
Summary:
See PHI1764. See PHI1802. Address two resolution behaviors for FutureProxy:
- FutureProxy may throw an exception directly from iteration via "FutureIterator" (see PHI1764). This is wrong: futures should throw only when resolved.
- FutureProxy can not change an exception into a result, or a result into an exception, or an exception into a different exception. Being able to proxy the full range of result and exception behavior is useful, particularly for Conduit (see PHI1802).
Make "FutureProxy" more robust in how it handles exceptions from proxied futures.
Test Plan:
Used this script to raise an exception during result processing:
```
<?php
require_once 'support/init/init-script.php';
final class ThrowingFutureProxy
extends FutureProxy {
protected function didReceiveResult($result) {
throw new Exception('!');
}
}
$future = new ImmediateFuture('quack');
$proxy = new ThrowingFutureProxy($future);
$iterator = new FutureIterator(array($proxy));
foreach ($iterator as $resolved) {
try {
$resolved->resolve();
} catch (Exception $ex) {
echo "Caught exception properly on resolution.\n";
}
}
```
Before this change, the exception is raised in the `foreach()` loop. After this change, the exception is raised at resolution time.

The "land" workflow also has a potentially dangerous behavior: if you have "master > A > B > C" and "arc land C", it will land A, B, and C. However, an updated version of A or B may exist elsewhere in the working copy. If it does, "arc land" will incorrectly land an out-of-date set of changes.
To find newer versions of "A" and "B", we need to search backwards from all local markers to the nearest outgoing marker, then compare the sets of changes we find to the sets of changes selected by "arc land".
This is also roughly the workflow that "arc branches", etc., need to show local markers as a tree, and starting in "arc branches" allows the process to be visualized.
As implemented here ,this rendering is still somewhat rough, and the selection of "outgoing markers" isn't good. In Mercurial, we may plausibly be able to use phase markers, but in Git we likely can't guess the right behavior automatically and probably need additional configuration.
Test Plan: Ran "arc branches" and "arc bookmarks" in Git and Mercurial.

Summary:
Ref T13546. When running "arc branches", we want to show all unpublished commits. This is often a different set of commits than "commits not present in any remote".
Attempt to identify published commits by using the permanent ref rules in Phabricator.
Test Plan: Ran "arc look published", saw sensible published commits in Git.

Summary:
Ref T13546. Query and associate known Phabricator repositories to working copy remotes by normalizing and comparing URIs.
This primarily gives us access to "permanentRefRules" so we can tell which branches have published changes.
Test Plan: Ran "arc look remotes" in Git and Mercurial working copies, saw repositories map properly.

Summary:
Ref T13546. Currently, "arc which" provides some amount of inspection but it generally isn't very helpful to users and is too limited and inflexible. "arc inspect" is an internal/debugging workflow.
The new "arc look" is much more aggressively unhelpful.
Test Plan: I'm not sure if this command should allow you to continue at night, because it's too dark.

Summary: Ref T13546. Expose remote refs for inspection via "arc inspect". For now, this only works in Mercurial.
Test Plan: Ran "arc inspect remote(default)" in Mercurial, got a ref out.

Summary: Ref T13546. Move toward smarter remote repository lookup by providing URI normalization code in Arcanist. This diff duplicates code from Phabricator; the next change will collapse it.
Test Plan: Ran unit tests.

Summary:
Ref T13546. Pull some small utility changes out of the deeper stack of "land/markers" changes.
"phutil_partition()" makes it easier to write code that loops over a list grouping elements, then acts on each group. This kind of code is not terribly common, but often feels awkward when implemented with raw primitives.
"msortv()" can support "natural" sorting, which sorts "feature1", "feature2", ..., "feature10" in a more human-readable order.
Test Plan: Ran unit tests, used new behaviors elsewhere in "arc markers" workflows.

Summary:
Ref T13546. In a future change, I'm providing a fancier version of "arc branches" that requires more sophisticated table rendering.
Implement a new view which can do some fancier things, like handle alignment of multi-line table cells.
Test Plan: See future changes.
