This is the last step before supporting extdiff -S. It maintains the existing
behavior of diffing the largefile standins instead of the largefiles themselves.
Note however that the standins are not updated immediately upon modification, so
uncommitted largefile changes are ignored, as they previously were, even with
the diff command.
If revlog file is corrupted, it can have parent pointing to invalid revision.
So we should validate it before updating nothead[], phases[], seen[], etc.
Otherwise it would cause segfault at best.
We could use "rev" instead of "maxrev" as upper bound, but I think the explicit
"maxrev" can clarify that we just want to avoid possible buffer overflow
vulnerability.
Before this patch, we were stripping temporary commits at the end of a histedit
whether it was successful or not. If we can create obs markers, we should
create them instead of stripping because it is faster and safer.
Before this patch, censored file should be exactly "a path relative to
repository root" regardless of current working directory, because "hg
censor" passes "path" to "repo.file()" directly without any
preparations.
To make various path forms available like other Mercurial commands,
this patch gets a target file path in the way of "hg parents FILE".
Getting "wctx" is relocated to reuse "wctx" for efficiency.
A fix for issue2653 with f5abbf51a76e introduced a discrepancy how default
branch should be denoted when converting with branchmap from different SCM.
E.g. for Git and Mercurial you need to use 'default' whilst for Perforce and
SVN you had to use 'None'. This changeset unifies 'default' for such purposes
whilst falling back to 'None' when no 'default' mapping specified.
Before this patch, 'hg shelve -i' under non-interactive mode suggests
'use commit instead', and it obviously incorrect, because what user
wants to do isn't 'commit' but 'shelve'.
To omit incorrect 'commit' suggestion at 'hg shelve -i', this patch
specifies 'None' for 'cmdsuggest' argument of 'cmdutil.dorecord()'.
Before this patch, 'hg qrefresh -i' under non-interactive mode
suggests 'use qrefresh instead', and it obviously meaningless.
To omit meaningless 'qrefresh' suggestion at 'hg qrefresh -i', this
patch specifies 'None' for 'cmdsuggest' argument of 'cmdutil.dorecord()'.
Before this patch, 'hg qnew -i' under non-interactive mode suggests
'use qnew instead', and it obviously meaningless.
To omit meaningless 'qnew' suggestion at 'hg qnew -i', this patch adds
internal function '_qrecord()' and specifies 'cmdsuggest' for each of
'qrecord' and 'qnew' separately.
Before this patch, 'hg commit -i' under non-interactive mode suggests
'use commit instead', and it obviously meaningless.
This patch makes 'record.record'()' examine 'ui.interactive()' and
show suggestion by itself before calling 'commands.commit()'.
This allows 'commands.commit()' to specify 'None' for 'cmdsuggest'
argument of 'cmdutil.dorecord()' to omit meaningless 'commit'
suggestion at 'hg commit -i'.
Just to be consistent with log and shortlog links, graph links should have a
revision context too. And the same goes for the graph page, where it's log and
shortlog links that should have context.
Previously all git remotes were created as "remote/foo". This patch adds a
configuration option for deciding what the prefix should be. This is useful if
you want the bookmarks to be "origin/foo" like they are in git, or if you're
integrating with the remotenames extension and don't want the local remote/foo
bookmarks to overlap with the remote foo bookmarks.
Instead of re-parsing quoted strings as templates, the tokenizer can delegate
the parsing of nested template strings to the parser. It has two benefits:
1. syntax errors can be reported with absolute positions
2. nested template can use quotes just like shell: "{"{rev}"}"
It doesn't sound nice that the tokenizer recurses into the parser. We could
instead make the tokenize itself recursive, but it would be much more
complicated because we would have to adjust binding strengths carefully and
put dummy infix operators to concatenate template fragments.
Now "string" token without r"" never appears. It will be removed by the next
patch.
It's sometimes handy to, say, have a url always point to branch head, not just
at the current branch head by node hash. Previously, this was only possible by
manually editing url and replacing node hash with branch/tag/bookmark name. It
wasn't very convenient, or easy - in case the name contained special
characters that needed to be urlencoded.
Let's have /branches, /tags and /bookmarks pages in paper and coal style
provide links both to symbolic revisions and to node hashes.
This feature was wished for in issue3594.
It's possible to have a branch/tag/bookmark with all kinds of special
characters, such as {}/\!?. While not very conveniently, symbolic revisions
with such characters work from command line if user correctly quotes the
characters. These characters also work in hgweb, when they are properly
encoded, with one exception: '/' (forward slash, urlencoded as '%2F'), which
was getting decoded before hgweb could parse it as a part of PATH_INFO.
Because of that, hgweb was seeing it as any other forward slash, that is, as
just another url parts separator.
For example, if user wanted to see the content of dir/file at bookmark
'feature/eggs', url could be: '/file/feature%2Feggs/dir/file'. But hgweb tried
to find a revision 'feature' and get contents of 'eggs/dir/file'.
To fix this, let's assume forward slashes are doubly-urlencoded (%252F), so
CGI/WSGI server decodes it into %2F. Then we can decode %2F in the revision
part of the url into an actual '/' character.
Making hgweb produce such urls will be done in the next 2 patches.
Before this patch, backups to be discarded are decided by steps below
at 'hg unshelve' or so:
1. list '(st_mtime, filename)' tuples of each backups up
2. sort list of these tuples, and
3. discard backups other than 'maxbackups' ones at the end of list
This doesn't work well in the case below:
- "sort by name" order differs from actual backup-ing order, and
- some of backups have same timestamp
For example, 'test-shelve.t' satisfies the former condition:
- 'default-01' < 'default-1' in "sort by name" order
- 'default-1' < 'default-01' in actual backup-ing order
Then, 'default-01' is discarded instead of 'default-1' unexpectedly,
if they have same timestamp. This failure appears occasionally,
because the most important condition "same timestamp" is timing
critical.
To avoid such unexpected discarding, this patch keeps old backups if
timestamp can't decide exact order of them.
Timestamp of the border backup (= the oldest one of recent
'maxbackups' ones) as 'bordermtime' is used to examine whether
timestamp can decide exact order of backups.
This is the simplest way to handle wdir() revision in revset. None didn't
work well because revset heavily depends on integer operations such as min(),
max(), sorted(), x:y, etc.
One downside is that we cannot do "wctx.rev() in set" because wctx.rev() is
still None. We could wrap the result set by wdirproxyset that translates None
to wdirrev, but it seems overengineered at this point.
result = getset(repo, subset, tree)
if 'wdir' in funcsused(tree):
result = wdirproxyset(result)
Test cases need the '(all() + wdir()) &' hack because we have yet to fix the
bootstrapping issue of null and wdir.
Because we want to eliminate "if"s in the default template, it makes sense to
display wdirrev/wdirnode values for now. wdir() is still experimental, so the
output of "log -r'wdir()'" may change in future.
Many 3rd party consumers of Mercurial have created wrappers to
essentially perform clone+share as a single operation. This is
especially popular in automated processes like continuous integration
systems. The Jenkins CI software and Mozilla's Firefox release
automation infrastructure have both implemented custom code that
effectively perform clone+share. The common use case here is that
clients want to obtain N>1 checkouts while minimizing disk space and
network requirements. Furthermore, they often don't care that a clone
is an exact mirror of a remote: they are simply looking to obtain
checkouts of specific revisions.
When multiple third parties implement a similar feature, it's a good
sign that the feature is worth adding to the core product. This patch
adds support for an easy-to-use clone+share feature.
The internal "clone" function now accepts options to control auto
sharing during clone. When the auto share mode is active, a store will
be created/updated under the base directory specified and a new
repository pointing to the shared store will be created at the path
specified by the user.
The share extension has grown the ability to pass these options into
the clone command/function.
No command line options for this feature are added because we don't
feel the feature will be popular enough to warrant their existence.
There are two modes for auto share mode. In the default mode, the shared
repo is derived from the first changeset (rev 0) in the remote
repository. This enables related repositories existing at different URLs
to automatically use the same storage. In environments that operate
several repositories (separate repo for branch/head/bookmark or separate
repo per user), this has the potential to drastically reduce storage
and network requirements. In the other mode, the name is derived from the
remote's path/URL.
To detect change of a file without redundant comparison of file
content, dirstate recognizes a file as certainly clean, if:
(1) it is already known as "normal",
(2) dirstate entry for it has valid (= not "-1") timestamp, and
(3) mode, size and timestamp of it on the filesystem are as same as
ones expected in dirstate
This works as expected in many cases, but doesn't in the corner case
that changing a file keeps mode, size and timestamp of it on the
filesystem.
The timetable below shows steps in one of typical such situations:
---- ----------------------------------- ----------------
timestamp of "f"
----------------
dirstate file-
time action mem file system
---- ----------------------------------- ---- ----- -----
N *** ***
- change "f" N
- execute 'hg commit -i'
- backup "f" with timestamp N
- revert "f" by 'merge.update()' N
with 'partially'
- apply selected hunks N
by 'patch.patch()'
- 'repo.commit()'
- 'dirstate.normal("f")' N
N+1
- 'dirstate.write()' N N
- restore "f" N+1
- restore timestamp of "f" N
- 'hg status' shows "f" as "clean" N N N
---- ----------------------------------- ---- ----- -----
The most important point is that 'dirstate.write()' is executed at N+1
or later. This causes writing dirstate timestamp N of "f" out
successfully. If it is executed at N, 'parsers.pack_dirstate()'
replaces timestamp N with "-1" before actual writing dirstate out.
This issue can occur when 'hg commit -i' satisfies conditions below:
- the file is committed partially, and
- mode and size of the file aren't changed before and after committing
The root cause of this issue is that (maybe partially changed) files
are restored with original timestamp but dirstate isn't updated for
them.
To detect changes of files correctly, this patch applies
'dirstate.normallookup()' on restored files. Status check is needed
before 'dirstate.normallookup()', because status other than "n(ormal)"
should be kept at failure of committing.
This patch doesn't examine whether each files are committed fully or
partially, because interactive hunk selection makes it difficult.
After this change, timetable is changed as below:
---- ----------------------------------- ----------------
timestamp of "f"
----------------
dirstate file-
time action mem file system
---- ----------------------------------- ---- ----- -----
N *** ***
- change "f" N
- execute 'hg commit -i'
- backup "f" with timestamp N
- revert "f" by 'merge.update()' N
with 'partially'
- apply selected hunks N
by 'patch.internalpatch()'
- 'repo.commit()'
- 'dirstate.normal("f")' N
N+1
- 'dirstate.write()' N N
- restore "f" N+1
- restore timestamp of "f" N
----------------------------------- ---- ----- -----
- normallookup("f") -1
- release wlock
- 'dirstate.write()' -1 -1 N
----------------------------------- ---- ----- -----
- 'hg status' shows "f" as "clean" -1 -1 N
---- ----------------------------------- ---- ----- -----
To reproduce this issue in tests certainly, this patch emulates some
timing critical actions as below:
- change "f" at N
'touch -t 200001010000' before command invocation changes mtime of
"f" to "2000-01-01 00:00" (= N).
- apply selected hunks at N
'patch.internalpatch()' with 'fakepatchtime.py' explicitly changes
mtime of patched files to "2000-01-01 00:00" (= N).
- 'dirstate.write()' at N+1 (or "not at N")
'pack_dirstate()' uses actual timestamp at runtime as "now", and
it should be different from the "2000-01-01 00:00" of "f".
BTW, in 'test-commit-interactive.t', files are sometimes treated as
modified , even though they are just committed fully via 'hg commit
-i' and 'hg diff' shows nothing for them.
Enabling win32text causes EOL style mismatching below:
- files are changed in LF style EOL
=> files restored after committing uses LF style EOL (1)
- 'merge.update()' reverts files in CRLF style EOL
- 'patch.internalpatch()' changes files in CRLF style EOL
=> 'dirstate.normal()' via 'repo.commit()' uses the size of files
in CRLF style EOL (2)
Therefore, fully committed files are treated as "modified", because
'lstat()' returns size of (1) restored files in LF style EOL, but
dirstate expects size of (2) committed files in CRLF style EOL.
After this patch, 'dirstate.normallookup()' on committed files forces
subsequent 'hg status' to examine changes exactly, and fully committed
files are treated as clean as expected.
This is reason why this patch also does:
- add some 'hg status' checking status of fully committed files
- clear win32text configuration before size/timestamp sensitive examination
To detect change of a file without redundant comparison of file
content, dirstate recognizes a file as certainly clean, if:
(1) it is already known as "normal",
(2) dirstate entry for it has valid (= not "-1") timestamp, and

---- ----------------------------------- ---- ----- -----
The most important point is that 'dirstate.write()' is executed at N+1
or later. This causes writing dirstate timestamp N of "f" out
successfully. If it is executed at N, 'parsers.pack_dirstate()'
replaces timestamp N with "-1" before actual writing dirstate out.
This issue can occur when 'hg transplant' satisfies conditions below:
- multiple revisions to be transplanted change the same file
- those revisions don't change mode and size of the file, and
- the 2nd or later revision of them fails after changing the file
The root cause of this issue is that files are changed without
flushing in-memory dirstate changes via 'repo.commit()' (even though
omitting 'dirstate.normallookup()' on files changed by 'patch.patch()'
for efficiency also causes this issue).
To detect changes of files correctly, this patch writes in-memory
dirstate changes out explicitly after marking files as clean in
'committablectx.markcommitted()', which is invoked via
'repo.commit()'.
After this change, timetable is changed as below:
---- ----------------------------------- ----------------
timestamp of "f"

To reproduce this issue in tests certainly, this patch emulates some
timing critical actions as below:
- change "f" at N
'patch.patch()' with 'fakepatchtime.py' explicitly changes mtime
of patched files to "2000-01-01 00:00" (= N).
- 'dirstate.write()' via 'repo.commit()' at N
'fakedirstatewritetime.py' forces 'pack_dirstate()' to use
"2000-01-01 00:00" as "now", only if 'pack_dirstate()' is invoked
via 'committablectx.markcommitted()'.
- 'dirstate.write()' via releasing wlock at N+1 (or "not at N")
'pack_dirstate()' via releasing wlock uses actual timestamp at
runtime as "now", and it should be different from the "2000-01-01
00:00" of "f".
BTW, this patch doesn't test cases below, even though 'patch.patch()'
is used similarly in these cases:
1. failure of 'hg import' or 'hg qpush'
2. success of 'hg import', 'hg qpush' or 'hg transplant'
Case (1) above doesn't cause this kind of issue, because:
- if patching is aborted by conflicts, changed files are committed
changed files are marked as CLEAN, even though they are partially
patched.
- otherwise, dirstate are fully restored by 'dirstateguard'
For example in timetable above, timestamp of "f" in .hg/dirstate
is restored to -1 (or less than N), and subsequent 'hg status' can
detect changes correctly.
Case (2) always causes 'repo.status()' invocation via 'repo.commit()'
just after changing files inside same wlock scope.
---- ----------------------------------- ----------------
timestamp of "f"

dirstate file-
time action mem file system
---- ----------------------------------- ---- ----- -----
N *** ***
- make file "f" clean N
- execute 'hg foobar'

(e.g. via dirty check
or previous 'repo.commit()')
- change "f", but keep size N
- 'repo.status()' (*1)
(via 'repo.commit()')
---- ----------------------------------- ---- ----- -----
At a glance, 'repo.status()' at (*1) seems to cause similar issue (=
"changed files are treated as clean"), but actually doesn't.
'dirstate._lastnormaltime' should be N at (*1) above, because
'dirstate.normal()' via dirty check is finished at N.
Therefore, "f" changed at N (= 'dirstate._lastnormaltime') is forcibly
treated as "unsure" at (*1), and changes are detected as expected (see
'dirstate.status()' for detail).
If 'hg import' is executed with '--no-commit', 'repo.status()' isn't
invoked just after changing files inside same wlock scope.
But preceding 'dirstate.normal()' is invoked inside another wlock
scope via 'cmdutil.bailifchanged()', and in-memory changes should be
flushed at the end of that scope.
Therefore, timestamp N of clean "f" should be replaced by -1, if
'dirstate.write()' is invoked at N. It means that condition of this
issue isn't satisfied.
This extension fakes "mtime" of patched files to emulate invoking
'patch.internalpatch()' at the specific time.
This is useful to reproduce timing critical issues fixed in subsequent
patches.
To detect change of a file without redundant comparison of file
content, dirstate recognizes a file as certainly clean, if:
(1) it is already known as "normal",
(2) dirstate entry for it has valid (= not "-1") timestamp, and
(3) mode, size and timestamp of it on the filesystem are as same as
ones expected in dirstate
This works as expected in many cases, but doesn't in the corner case
that changing a file keeps mode, size and timestamp of it on the
filesystem.
The timetable below shows steps in one of typical such situations:

- make file "f" clean N

- change "f", but keep size N
N+1
- release wlock
- 'dirstate.write()' N N
- 'hg status' shows "f" as "clean" N N N
---- ----------------------------------- ---- ----- -----
The most important point is that 'dirstate.write()' is executed at N+1
or later. This causes writing dirstate timestamp N of "f" out
successfully. If it is executed at N, 'parsers.pack_dirstate()'
replaces timestamp N with "-1" before actual writing dirstate out.
Occasional test failure for unexpected file status is typical example
of this corner case. Batch execution with small working directory is
finished in no time, and rarely satisfies condition (2) above.
This issue can occur in cases below;
- 'hg revert --rev REV' for revisions other than the parent
- failure of 'merge.update()' before 'merge.recordupdates()'
The root cause of this issue is that files are changed without
flushing in-memory dirstate changes via 'repo.commit()' (even though
omitting 'dirstate.normallookup()' on changed files also causes this
issue).
To detect changes of files correctly, this patch writes in-memory
dirstate changes out explicitly after marking files as clean in
'workingctx._checklookup()', which is invoked via 'repo.status()'.
After this change, timetable is changed as below:

To reproduce this issue in tests certainly, this patch emulates some
timing critical actions as below:
- timestamp of "f" in '.hg/dirstate' is -1 at the beginning
'hg debugrebuildstate' before command invocation ensures it.
- make file "f" clean at N
- change "f" at N
'touch -t 200001010000' before and after command invocation
changes mtime of "f" to "2000-01-01 00:00" (= N).
- invoke 'dirstate.write()' via 'repo.status()' at N
'fakedirstatewritetime.py' forces 'pack_dirstate()' to use
"2000-01-01 00:00" as "now", only if 'pack_dirstate()' is invoked
via 'workingctx._checklookup()'.
- invoke 'dirstate.write()' via releasing wlock at N+1 (or "not at N")
'pack_dirstate()' via releasing wlock uses actual timestamp at
runtime as "now", and it should be different from the "2000-01-01
00:00" of "f".
BTW, this patch also changes 'test-largefiles-misc.t', because adding
'dirstate.write()' makes recent dirstate changes visible to external
process.
This extension fakes 'now' for 'parsers.pack_dirstate()' to emulate
invoking 'dirstate.write()' at the specific time, only when
'dirstate.write()' is invoked via functions below:
- 'workingctx._checklookup()' (= 'repo.status()')
- 'committablectx.markcommitted()'
This is useful to reproduce timing critical issues fixed in subsequent
patches.
This creates the convert.hg.sourcename config option which will embed a user
defined name into each commit created by the convert. This is useful when using
the convert extension to merge several repositories together and we want to
record where each commit came from.
Previously convert could only take one '--rev'. This change allows the user to
specify multiple --rev entries. For instance, this could allow converting
multiple branches (but not all branches) at once from git.
In this first patch, we disable support for this for all sources. Future
patches will enable it for select sources (like git).
For some time, bookmark can and should be moved in the transaction. This
changeset migrates the 'hg bookmarks' commands to use a transaction.
Tests regarding rollback and transaction hooks are impacted for
obvious reasons. Some have to be slightly updated to keep testing the
same things. Some can just be dropped because they do not make sense
anymore.
In some cases we do not want to convert tags from the source repo to be tags in
the target repo (for instance, in a large repository, hgtags cause scaling
issues so we want to avoid them). This adds a config option to disable
converting tags.
wdirrev/wdirnode identifiers are still experimental, but {node} is mapped to
wdirnode. So {rev} should do the same for consistency.
I'm not sure if templatekw can import scmutil. If not, we should move intrev()
to node module.
Because we defined the working-directory revision is INT_MAX, it makes sense
that "hg log -r 'wdir()'" displays the "parent:" field. This is the same for
two revisions that are semantically contiguous but the intermediate revisions
are hidden.
This will prevent crash by "hg log -r 'wdir()' -Tdefault". We could use the
pseudo ff... hash introduced by 187c3ec3d83f, but it isn't proven idea yet.
For now, I want to make "hg log" just works in order to test 'wdir()' revset.
Note that unlike its name, "{manifest}" is not a list of files in that
revision, but a pair of (manifestrev, manifestnode).
Before this patch, there is no way to add customized features to
`hghave` without changing `hghave` and `hghave.py` themselves.
This decreases reusability of `run-tests.py` framework for third party
tools, because they may want to examine custom features at runtime
(e.g. existence of some external tools).
To allow adding customized features at runtime, this patch makes
`hghave` import `hghaveaddon` module, only when `hghaveaddon.py` file
can be found in directories below:
- `TESTDIR` for invocation via `run-tests.py`
- `.` for invocation via command line
The path to the directory where `hghaveaddon.py` should be placed is
added to `sys.path` only while importing `hghaveaddon`, because:
- `.` may not be added to `PYTHONPATH`
- adding additional path to `sys.path` may change behavior of
subsequent `import` for other features
`hghave` is terminated with exit code '2' at failure of `import
hghaveaddon`, because exit code '2' terminates `run-tests.py`
immediately.
This is a one of preparations for issue4677.
Before this patch, `import-checker.py` exits with non-0 code, if no
error is detected. This is unusual as Unix command.
This change may be a one of preparations for issue4677, because this
can avoid extra explanation about unusual exit code of
`import-checker.py` for third party tool developers.
Before this patch, `RUNTESTDIR` is added to `PATH`, but `TESTDIR`
isn't.
This doesn't cause any problems, if `run-tests.py` runs in `tests`
directory of Mercurial source tree. In this case, `RUNTESTDIR` should
be equal to `TESTDIR`.
On the other hand, if `run-tests.py` runs in `tests` of third party
tools, commands in that directory should be executed with explicit
`$TESTDIR/` prefix in `*.t` test scripts. This isn't suitable for the
policy "drop explicit $TESTDIR from executables" of Mercurial itself
(see fcb1c7d8c36e).
BTW, fcb1c7d8c36e describes that "$TESTDIR is added to the path" even
though `TESTDIR` isn't added to `PATH` exactly speaking, because
`TESTDIR` and `RUNTESTDIR` weren't yet distinguished from each other
at that time.
This is a one of preparations for issue4677.
Before this patch, there is no way to refer files under `tests` or so
of Mercurial source tree, when `run-tests.py` runs in `tests` of third
party tools. In this case, `TESTDIR` refers the latter `tests`.
This prevents third party tools from using useful tools in Mercurial
source tree (e.g. `contrib/check-code.py`).
This patch adds `RUNTESTDIR` environment variable to refer `tests` of
Mercurial source tree, in which `run-tests.py` now running is
placed. For example, tests of third party tools can refer
`contrib/check-code.py` in Mercurial source tree as
`$RUNTESTDIR/../contrib/check-code.py`.
BTW, for similarity with `TESTDIR` referring `test*s*` directory,
newly added environment variable isn't named as `RUNTEST*S*DIR`. In
addition to it, the corresponded local variable is also named as
`runtestdir`.
This is a one of preparations for issue4677.
Before this patch, `run-tests.py` executes `hghave` by the path
relative to `TESTDIR` (= cwd of `run-tests.py` running).
This prevents third party tools for Mercurial from running
`run-tests.py`, which is placed in `tests` of Mercurial source tree,
in `tests` of own source tree. In such cases, `TESTDIR` refers the
latter `tests`, and `hghave` doesn't exist in it.
This is a one of preparations for issue4677.
This maintains the previous behavior of expanding {latesttag} to a string
containing all of the tags, joined by ':'. But now it also allows list type
operations.
I'm unsure if the plural handling is correct (i.e. it seems like it is usually
"{foos % '{foo}'}"), but I guess we are stuck with this because the singular
form previously existed.
Archive is putting a value with the same name in the metadata file, to count all
of the changes not covered by the latest tag, instead of just along the longest
path. It seems that this would be useful to have on the command line as well.
It might be nice for the name to start with 'latesttag' so that it is grouped
with the other tag keywords, but I can't think of a better name.
The initial version of this counted a clean wdir() and '.' as the same value,
and a dirty wdir() as the same value after it is committed. Yuya objected on
the grounds of consistency [1]. Since revsets can be used to conditionally
select a dirty wdir() or '.' when clean, I can build the version string I need
and will defer to him on this.

The output has apparently changed slightly since this version. Since they are
just commits without any obvious importance to the test, and I can't figure out
how to glob them away, silence them.

This will keep the backup directory from growing indefinitely. The number of
backups to keep can be set using the shelve.maxbackups config option (defaults
to 10 backups).
Instead of being deleted, shelve files are now moved into the .hg/shelve-backup
directory. This is designed similarly to how strip saves backups into
.ht/strip-backup. The goal is to prevent data loss especially when using
unshelve. There are cases in which a user can complete an unshelve but lose
some of the data that was shelved by, for example, resolving merge conflicts
incorrectly. Storing backups will allow the user to recover the data that was
shelved, at the expense of using more disk space over time.
