This is a followup to 12441ef4442f. Since there's no way to ensure that more
drive letters than C: exist, this seems like the only way to test it. This is
enough to catch the 12441ef4442f scenario, as well as CWD outside of the repo
when the path isn't prefixed with path/to/repo.
It wasn't easy to extend the pathauditor to check symlink traversal across
subrepos because pathauditor._checkfs() rejects a directory having ".hg"
directory. That's why I added the explicit islink() check.
No idea if this patch is necessary after we've fixed the issue5730 by
splitting submerge() into planning and execution phases.
os.path.relpath() exploded if the 'root' and 'cwd' directories had different
drive letters. I noticed this in TortoiseHg when typing a fileset into the
filter, and it kept complaining until the closing '()' was typed. This was
reproducible on the command line with:

The original condition was a bit harsh for extension authors since third-party
extensions need to preserve compatibility with older Mercurial versions, where
no defaults would be loaded from the configtable. So let's silence the warning
if the given default value matches, which should be harmless.
After a refactoring, _toolstr stopped having default="" as one of it's args,
therefore when called without a default it returns None and not "". This causes
concatenation to fail.
We've found a severe perf regression in `hg update` caused by the path conflict
checking code. The next patch will disable this by default.

When a dirstate backup is restored, it is possible that no actual changes to
the dirstate have been made. In this case, the backup is still a hardlink
to the original dirstate.
Unfortunately, `os.rename` silently fails (nothing happens, and no error
occurs) when `src` and `dst` are hardlinks to the same file. As a result,
the backup is left lying around. Over time, these files accumulate.
When restoring dirstate backups, check if the backup and the dirstate are
the same file, and if so, just delete the backup.

A recent refactor added a layer of abstraction to the dirstate which makes doing
things like 'foo in dirstate' now require some extra Python attribute lookups.
This is causing a 100ms slow down in hg status for mozilla-central.
The fix is to hoist the inner dict's functions onto the main class once the lazy
loading it complete, as well as store the actual functions before doing the
status loop (as is done for other such functions).
In my testing, it seems to address the performance regression, but we'll
need to see the perf run results to know for sure.

Before the recent refactor, we would not load the entire map until it was
accessed. As part of the refactor, that got lost and even just trying to load
the dirstate parents would load the whole map. This caused a perf regression
(issue5713) and a regression with static http serving (issue5717).
Making it lazy loaded again fixes both.

A future diff will move the lazy loading aspect of dirstate to the dirstatemap
class. This means it requires a slightly different strategy of clearing than
just reinstantiating the object (since just reinstantiating the object will
lazily load the on disk data again later instead of remaining permanently
empty).
So let's give it it's own clear function.

The same applies to '?' if --quiet is used (or any of the other states if some

clearly.
This seems a bit hacky, but works well. There should be no reason that
static-http repo had to load dirstate.
Initially I tried to proxy os.stat() call through vfs so that statichttpvfs
could hook it, but there wasn't a good error value which the statichttpvfs
could return to get around the util.filestat issue.
Right now, successorsetverb only needs successors to compute the verb. But we
will want use additional information (effect-flags and operation) in the near

Add the markers parameter now so extensions (like Evolve) could wrap the

As successorsetverb now takes both successorset and markers parameters, rename
it to obsfateverb, successorsetandmarkersverb was too long.

Previously, the caller was responsible for creating the directory structure of

And introduce a new "apply" operation verb for this case as suggested in
issue5096. This replaces the no longer used "revert" operation.
In interactive revert, when reverting to something else that the parent
revision, display an "apply this change" message with a diff that is not
reversed.
The rationale is that `hg revert -i -r REV` will show hunks of the diff from
the working directory to REV and prompt the user to select them for applying
(to working directory). This contradicts 79cc693b4406 in which it was
decided to have the "direction" of prompted hunks reversed. Later on
[1], there was a broad consensus (but no decision) towards the "as to
be applied direction". Now that --interactive is no longer experimental
(97d754ba45c4), it's time to switch and thus we drop no longer used
"experimental.revertalternateinteractivemode" configuration option.
[1]: https://www.mercurial-scm.org/pipermail/mercurial-devel/2016-November/090142.html
.. feature::
When interactive revert is run against a revision other than the working
directory parent, the diff shown is the diff to *apply* to the working directory,
rather than the diff to *discard* from the working copy. This is in line with
related user experiences with `git` and appears to be less confusing with
`ui.interface=curses`.
The short options "-c" and "-C" may be confusing for a novice reading the
documentation. Let's try to be more explicit, also mentioning the equivalent
long options ("--check" and "--clean") in the comments.
Currently, specifying both a line-range pattern and a bare file pattern
results in an AND operation whereas we probably want an OR so that bare file
patterns are like a line-range pattern with all lines specified.
So, until this works as expected, we disable this.
When a file is binary patch.trydiff() would yield None for 'hunkrange'. Handle
this case in the hunksfilter() callback.
Add tests with and without diff.git option as binary handling differs
depending on this option's value.

Yuja's comment on the original obsfate about how we would translate obsfate

changeset_printer.
It will be easier to understand for end-users, easier to translate and closer

An empty entry in the revlog may happen for two reasons:
- when the file is empty, and the revlog stores a snapshot;
- when there is a merge and both parents were identical.
`hg debugindex -m | awk '$3=="0"{print}' | wc -l` gives 1917 of such entries
in my clone of pypy, and 113 on my clone of mercurial.
These empty revision may be located at the end of a sparse chain, and in some

fsmonitor can significantly speed up operations on large working
directories. But fsmonitor isn't enabled by default, so naive users
may not realize there is a potential to make Mercurial faster.
This commit introduces a warning to working directory updates when
fsmonitor could be used.
The following conditions must be met:
* Working directory is previously empty
* New working directory adds >= N files (currently 50,000)
* Running on Linux or MacOS
* fsmonitor not enabled
* Warning not disabled via config override
Because of the empty working directory restriction, most users will
only see this warning during `hg clone` (assuming very few users
actually do an `hg up null`).
The addition of a warning may be considered a BC change. However, clone
has printed warnings before. Until recently, Mercurial printed a warning
with the server's certificate fingerprint when it wasn't explicitly
trusted for example. The warning goes to stderr. So it shouldn't
interfere with scripts parsing meaningful output.
The OS restriction was on the advice of Facebook engineers, who only
feel confident with watchman's stability on the supported platforms.

Since the ui objects can be created with the 'load' class method, it
is possible to lose the exit handlers information from the old ui instance. For
example, running 'test-bad-extension.t' leads to this situation where chg
creates a new ui instance which does not copy the exit handlers from the
earlier ui instance. For exit handlers, which are special cases anyways, it
probably makes sense to have a global state of the handlers. This would ensure
that the exit handlers registered once are definitely executed at the end of
the request.

Splitting at too small gaps might not be worthwhile. With this changeset,
we stop considering splitting on too small gaps. The threshold is configurable.
We arbitrarily pick 256K as a default value because it seems "okay".
Further testing on various repositories and setups will be needed to tune it.
The option name is 'experimental.sparse-read.min-gap-size`, and replaces
`experimental.sparse-read.min-block-size` which is not used any more.
The previous recursive approach was trying to optimise each read slice to have
a good density. It had the tendency to over-optimize smaller slices while
leaving larger hole in others.
The new approach focuses on improving the combined density of all the reads,
instead of the individual slices. It slices at the largest gaps first, as they
reduce the total amount of read data the most efficiently.
Another benefit of this approach is that we iterate over the delta chain only
once, reducing the overhead of slicing long delta chains.
On the repository we use for tests, the new approach shows similar or faster
performance than the current default linear full read.
The repository contains about 450,000 revisions with many concurrent
topological branches. Tests have been run on two versions of the repository:
one built with the current delta constraint, and the other with an unlimited
delta span (using 'experimental.maxdeltachainspan=0')
Below are timings for building 1% of all the revision in the manifest log using
'hg perfrevlogrevisions -m'. Times are given in seconds. They include the new
couple of follow-up changeset in this series.

I think there's a slight hole here in that a subrepo could be shared, removed
from .hgsub, and then it's not part of context.substate (so not iterated over).
But the push command has the same hole IIRC, and I think removing a subrepo is
an edge case.
The import hack is a copy/paste of subrepo.subrepo().
This will be used to setup unsharing subrepos. Usually cmdutil is used for
this purpose. But the implementation needs hg.copystore(), and the hg module
already imports cmdutil.
Before this changesets, a literal '.*:foo$' config would match a registered
'.*:foo$' generic. This is wrong since generic should be matched through
regular exception only. This changeset fixes this problem.
Thanks for to Yuya Nishihara for spotting the issue.
When the list of dates is empty, `min` and `max` would raises a ValueError.

This new debugcommand prints the capabilities of any remote in a human friendly

changesets.
We seem to have settled down on behavior changes here (nothing
matching revset `keyword(revert) and keyword(interactive)` since 4.2
was released), so let's go ahead and advertise this excellent feature.
.. feature:: revert --interactive
The revert command now accepts the flag --interactive to allow reverting
only some of the changes to the specified files.
We want a slightly weird format here so that it's easier to read, but
in order to preserve that we need to disable clang-format.
Differential Revision: https://phab.mercurial-scm.org/D1168
Now that all known options are declared, we setup a warning to make sure it will
stay this way.
We disable the warning in two tests checking other behavior with random options.
We add an experimental -L/--line-range option to 'hg log' taking file patterns
along with a line range using the (new) FILE,FROMLINE-TOLINE syntax where FILE
may be a pattern (matching exactly one file). The resulting history is similar
to what the "followlines" revset except that, if --patch is specified,
only diff hunks within specified line range are shown.
Basically, this brings the CLI on par with what currently only exists in hgweb
through line selection in "file" and "annotate" views resulting in a file log
with filtered patch to only display followed line range.
The option may be specified multiple times and can be combined with --rev and
regular file patterns to further restrict revisions. Usage of this option
requires --follow; revisions are shown in descending order and renames are
followed. Only the --graph option is currently not supported.
The UI is the result of a consensus from review feedback at:
https://www.mercurial-scm.org/pipermail/mercurial-devel/2017-October/106749.html
The implementation spreads between commands.log() and cmdutil module.
In commands.log(), the main loop may now use a "hunksfilter" factory (similar
to "filematcher") that, for a given "rev", produces a filtering function
for diff hunks for a given file context object.
The logic to build revisions from -L/--line-range options lives in
cmdutil.getloglinerangerevs() which produces "revs", "filematcher" and
"hunksfilter" information. Revisions obtained by following files' line range
are filtered if they do not match the revset specified by --rev option. If
regular FILE arguments are passed along with -L options, both filematchers are
combined into a new matcher.
.. feature::
Add an experimental -L/--line-range FILE,FROMLINE-TOLINE option to 'hg log'
command to follow the history of files by line range. In combination with
-p/--patch option, only diff hunks within specified line range will be
displayed. Feedback, especially on UX aspects, is welcome.
We add a 'hunksfilterfn' keyword argument in all functions of the call
stack from changeset_printer.show() to patch.diff(). This is a callable
that will be used to filter out hunks by line range and will be used in
the "-L/--line-range" option of "hg log" command introduced in the
following changesets.
We'll need the same logic in forthcoming changeset to handle --line-range
option in 'hg log' command.
The function lives in scmutil.py (rather than util.py) as it uses match and
pathutil modules.
Use the verbosity aware template keyword introduced earlier. It has the nice
property of being verbosity dependent but in order to customize the obsfate
part, users will need to replace the lobsfate definition from default mapfile
with the one using template functions (by copying the one from test-obsmarker-
template.t for example).
As it's a more advanced use-case, I'm more inclined to have the same code for
the {obsfate} keyword, in the changeset printer and in the default mapfile for
consistency.
But, the definition in default mapfile could be replaced with one based on
template filter to obsfate output customization if it is a big need for users.
Having an obsfate by default in log will be useful for users to understand why
they have obsolete and unstable changesets. Obsfate will only be shown for
obsolete changesets, which only happens if people opt-in to experimental feature.
But when obsolete changeset are visible, it is very useful to understand where
they are. Having it in log could be sufficient for most people, so they don't
have to learn a new command (like obslog which is itself useful in case of
divergences).
For example, when pulling and working directory parent become obsolete:
$ hg pull
...
working directory parent is obsolete! (f936c1697205)
This message comes from the Evolve extension.
Obsfate would comes handy:
$ hg log -G

Obsolescence is sometimes used only locally so the obs-marker users is always
the same. Showing the user in this case does not bring much values.
In the case where multiple users rewrite the commit, display the full list of

Introduce an obsfate printer that uses all helpers functions defined in
obsutil to get all the obsfate-related data and format a string according to
the current format in test-obsmarker-template.t.
Then, introduce an obsfate templatekw that uses the obsfateprinter to return a
list of strings.
The goal is not to replace existing obsfate template functions but to propose
a default, good-enough and easily usable obsfate definition for end-users that
don't want to customize it. Such output would ultimately get included in the
default log output.
Here are some output examples for a commit amended:
rewritten using amend as 5:a9b1f8652753 by test (at 1970-01-01 00:00 +0000)
Next patches will make the output dependent on the verbosity.
Exemple of use-cases:
For having the obsfate on a single-line between brackets:
{if(obsfate, " [{join(obsfate, "; ")}]")}
For having the obsfate in several lines:
{if(obsfate, "{obsfate % " Obsfate: {fate}\n"}")}
The heuristics algorithm find possible candidates for move/copy and then check

The part we are using for pull is now used for push too. As we no longer use
pushkey, pushkey hooks are no longer triggered. This is an obvious backward
incompatible change. We could artificially trigger the pushkey hook within the
bundle2 part, but this seemed too hacky to me.
An option would be to disable by default this new mechanism for a couple of
versions to help people migrate to `txnclose-phase`. I took the liberal and
optimistic path to just turn it on by default directly.

Push no longer triggers a pushkey hook when updating phases. Use the new

The shelve extensions import and call rebase content without loading the
extension. This is problematic as the config items rebase uses are not
declared and the default value are not set, etc...
The shelve extension should be using core utilities only and the necessary bit
should be moved from rebase into core. In the meantime, I'm taking a small
step to get config registration completed with minimal overhead. The rebase
extension is shipped with core so registering its config option within core is
not a big issue.
This is the last step needed before we can install a warning that enforces all
config to be registered.
We register the merge-tools config section (which has an arbitrary base config
value) and the possible sub-attribute. The sub-attribute has to be registered
first or at the same time otherwise the '.*' item would shadow them.
Merge tools could include "." in their name so we can't constrain any more
than just ".*".
Delta chains can become quite sparse if there is a lot of unrelated data between
relevant pieces. Right now, revlog always reads all the necessary data for the
delta chain in one single read. This can lead to a lot of unrelated data to be
read (see issue5482 for more details).
One can use the `experimental.maxdeltachainspan` option with a large value
(or -1) to easily produce a very sparse delta chain.
This change introduces the ability to slice the chunks retrieval into multiple
reads, skipping large sections of unrelated data. Preliminary testing shows
interesting results. For example the peak memory consumption to read a manifest
on a large repository is reduced from 600MB to 250MB (200MB without
maxdeltachainspan). However, the slicing itself and the multiple reads can have
an negative impact on performance. This is why the new feature is hidden behind
an experimental flag.
Future changesets will add various parameters to control the slicing heuristics.
We hope to experiment a wide variety of repositories during 4.4 and hopefully
turn the feature on by default in 4.5.
As a first try, the algorithm itself is prone to deep changes. However, we wish
to define APIs and have a baseline to work on.
When a merge commit creates an empty diff in the revlog, its offset may still
be quite far from the end of the previous chunk.
Skipping these empty chunks may reduce read size significantly.
In most cases, there is no gain, and in some cases, little gain.
On my clone of pypy, `hg manifest` reads 65% less bytes (96140 i/o 275943) for
revision 4260 by ignoring the only empty trailing diff.
For revision 2229, 35% (34557 i/o 53435)
Sadly, this is difficult to reproduce, as hg clone can make its own different
structure every time.
Move the logic to build bundle2 pushkey part into its dedicated function. It
will help to keep the logic clear when adding support for sending phases change
using 'phase-heads' part.
We are about to switch phase pushing from using pushkey to using a the new
dedicated binary part. We introduce the push race detection on its own to help
detect potential impact.
This part checks if revisions are still in the same phase as when the
bundle was generated. This is similar to what 'check:heads' or
'check:updated-heads' bundle2 part achieves for changesets.
We needs seems before we can move away from pushkey usage from phase since
pushkey has it own built-in push-race detection.

The on-disk file can contain draft root that are descendants of secret root.
The resulting phase computation is correct, but the phases root content is
not. I will send another series to introduce code that remove some of the
cases where this can happens, but we first need to damage control the existing
case.
After this changeset, we can no longer advertise secret changeset as draft
root.
Previously, only the top level repo was shared, and then any subrepos were
cloned on demand. This is problematic because commits to the parent repo would
write an updated .hgsubstate to the share source, but the corresponding subrepo
commit would be stuck in the local subrepo. That would prevent an update in the
source repo. We already go to great lengths to avoid having inconsistent repos
(e.g., `hg push -r rev` will push _everything_ in a subrepo, even if it isn't
referenced in one of the parent's outgoing commits). Therefore, this seems like
a bug fix, and there's no option to get the old behavior. I can't imagine the
previous behavior was useful to anybody.
There shouldn't be an issue with svn, since it is centralized. Maybe --git-dir
can be used for git subrepos, but I'll leave that to someone more familiar with
git.
An integer was previously being implicitly returned from commands.share(), which
caused dispatch() to start crashing when changing over to returning the shared
repo. All error paths appear to raise, so this can be hardcoded to success.
The clone command checks for 'is None' in a similar pattern, but since
hg.clone() always returns a tuple, that seems wrong?
.. fix:: Issue 5675
Creating a share of a repository with a Mercurial subrepository will now
share the subrepository.
and
.. bc::
Mercurial subrepositories are now shared instead of cloned when the parent
repository is shared. This prevents dangling subrepository references in the
share source. Previously shared repositories with cloned subrepositories
will continue to function unchanged.
__name__ is unicode, but we need bytes. For now, we'll make the
(mostly-safe) assumption that template filter names will be ascii.

Stops us from choking the templater on Python 3. With this patch
applied, much of hgweb works correctly in Python 3. The notable
exception is the graph page, which chokes because it gets node IDs as
str instead of bytes.

experimental.updatecheck was renamed into commands.update.check, use the
config system to provides the fallback on the old config name instead of
adding more code.

I may be a weird person for liking this style, but our C style is
historically nominally the Linux Kernel style, and when you configure
clang-format to be kernel-ish, this is what you get. If we want to
change it, we can do so by tweaking the formatter rules in the future.

Call the new _onfilemergefailure function when a merge tool reports failure
via a return code.

Depends on D931.
This patch introduces functions and a config option that will allow a user
to halt the merge if there are failures during a file merge. These functions
will be used in the next patch.

`commit --amend` and amend command in core and extensions rely on
cmdutil.amend() for amending a commit. So the logic to add a note to amend must
reside here. This patch assumes that note will be passed in opts dictionary to
the function and it will be passed to cleanupnodes and then createmarkers to
store the note in the obsmarker metadata.
After this patch, note can be stored on an amend changeset by passing notes as a
part of opts to cmdutil.amend().

This patch adds a metadata argument to cleanupnodes() which will be dict and can
be passed to obsmarker.createmarkers() and can be stored on the obsmarker.
In cases when obsolescence is not enabled, the metadata argument is useless.
This is a step towards storing a note in amend.

With in-memory merge, copy information needs to be stored in-memory, not in the
dirstate.
To make this transition easy, move the existing dirstate-based approach to
workingfilectx; that way, other implementations can choose to store it
somewhere else.

With in-memory merge, backup files might be overlayworkingfilectxs stored
in memory. But they could also be real files if the user's backup directory is
outside the working dir.
Rather than have two code paths everywhere, let's use arbitraryfilectx so they
can be consistent.

This patch adds support for storing the type of command which is going to run in
the func object. For this it does the following:
1) Add three possible values as attributes to the registrar.command class
2) Add a new argument to registrar.command._doregister function
3) Add a new attribute cmdtype to the func object
The type of command will be helpful in deciding what level of access on hidden
commits it can has.

That's more in line with what we want, and we know it's ASCII data
since that's all HTTP technically allows in headers anyway.

Rename 'devel.empty-changegroup' to 'devel.warn-empty- changegroup' in order
to clarify it controls a warning message.
No alias is installed since the previous configuration option was not
documented.
