As a part of migration to vfs, this patch uses "self.root", which can
be recognized as the path relative to "self.vfs", instead of "path"
argument.
This fix allows to make invocations of "util.makedirs()" and
"os.path.exists()" while ensuring repository directory in
"localrepository.__init__()" ones indirectly via vfs.
But this fix also raises issue 2528: "hg clone" with empty destination.
"path" argument is empty in many cases, so this issue can't be fixed
in the view of "localrepository.__init__()".
Before this patch, it is fixed by empty-ness check ("not name") of
exception handler in "util.makedirs()".
try:
os.mkdir(name)
except OSError, err:
if err.errno == errno.EEXIST:
return
if err.errno != errno.ENOENT or not name:
raise
This requires "localrepository.__init__()" to invoke "util.makedirs()"
with "path" instead of "self.root", because empty "path" is treated as
"current directory" and "self.root" becomes valid path.
But "hg clone" with empty destination can be detected also in
"hg.clone()" before "localrepository.__init__()" invocation, so this
patch re-fixes issue2528 by checking it in "hg.clone()".
As a part of migration to vfs, this patch uses "self.wvfs.join()"
instead of "os.path.join()", while initialization of fields in the
constructor of "localrepository" class.
As a part of migration to vfs, this patch moves path expansion API
invocations in the constructor of "localrepository" to the constructor
of "opener", because the root path to the repository is very important
to handle paths using non-ASCII characters correctly.
This patch also rearrange initialization order of "wvfs" field,
because it is required to initialize "self.root".
As a part of migration to vfs, this patch adds "vfs" fields to
"localrepository" class.
This allows new codes to access current "opener" objects related to
repositories via "vfs" fields, so patches referring to "vfs" will
replace referring to "opener" in time.
This patch also adds initializations for "vfs" fields to
"statichttprepository" class derived from it, because its constructor
doesn't invoke the constructor of "localrepository", so "vfs" fields
should be initialized explicitly as same as "opener" fields: it has no
working directory, so "wvfs" field is not added.
This speeds up status on a largefiles repo by synchronizing the largefiles dirstate to the
largefile's mtime upon update, preventing the files from coming back as "unsure" later,
requiring a check of the SHA1 sum.
Before this patch, MQ checks each subrepo synchronizations against the
working directory context, so ".hgsubstate" updating is not imported
into MQ revision correctly in cases below:
- qrefresh when current ".hgsubstate" is already synchronized with
each subrepos: you can reproduce this easily by just twice or more
qrefresh invocations
- qnew just after rollback of commit which updates ".hgsubstate"
This patch resolves this by checking subrepo states against:
- the parent of "qtop" for qrefresh, or
- the parent of working context otherwise
Even though the committed revision contains diff of ".hgsubstate", the
patch file created by qrefresh doesn't contain it, because:
- ".hgsubstate" is not listed up as one of target files of the patch
for reasons below, so diff of ".hgsubstate" is not imported into
patch file
- status of ".hgsubstate" in working directory is usually "clean"
- ".hgsubstate" is not specified explicitly by users
- the patch file is created before commit processing which updates
or creates ".hgsubstate" automatically, so there is no diff for it
at that time
This patch resolves this problem by:
- putting ".hgsubstate" into target list of the patch, if needed:
this allows "patch.diff()" to import diff of ".hgsubstate" into
patch file.
- creating the patch file after commit processing:
this updates ".hgsubstate" before "patch.diff()" invocation.
For the former fixing, this patch introduces "putsubstate2changes()"
to share same implementation with qnew. This is invoked only once per
qnew/qrefresh at most, so there is less performance impact.
This patch also omits "match" argument for "patch.diff()" invocation,
because "patch.diff()" ignores "match" if "changes" is specified.
If ".hgsubstate" is already listed up as one of commit targets, qnew
put diff of ".hgsubstate" twice into the patch file stored under
".hg/patches".
It causes rejections at applying such patches.
Other than the case like in added test script, this can also occur
when qnew is executed just after rolling back the committing updated
".hgsubstate".
This patch checks whether ".hgsubstate" is already listed up as one of
commit targets, and put it into the appropriate list only if it is not
listed up yet.
Plain 'hg help rollback' now looks like this:
$ hg help rollback
hg rollback
roll back the last transaction (dangerous)
This command should be used with care. There is only one level of
rollback, and there is no way to undo a rollback. It will also restore
the dirstate at the time of the last transaction, losing any dirstate
changes since that time. This command does not alter the working
directory.
Transactions are used to encapsulate the effects of all commands that
create new changesets or propagate existing changesets into a repository.
This command is not intended for use on public repositories. Once changes
are visible for pull by other users, rolling a transaction back locally
is ineffective (someone else may already have pulled the changes).
Furthermore, a race is possible with readers of the repository; for
example an in-progress pull from the repository may fail if a rollback is
performed.
Returns 0 on success, 1 if no rollback data is available.
options:
-n --dry-run do not perform actions, just print output
-f --force ignore safety measures
--mq operate on patch repository

The decision whether or not to store a full snapshot instead of a delta is done
based on the distance value calculated in _addrevision.builddelta(rev).
This calculation traditionally used the fact of deltas only using the previous
revision as base. Generaldelta mechanism is changing this, yet the calculation
still assumes that current-offset minus chainbase-offset equals chain-length.
This appears to be wrong.
This patch corrects the calculation by means of using the chainlength function
if Generaldelta is used.
Quite a few tests fail in noisy but meaningless ways when the test suite
is run with generaldelta enabled:
./run-tests.py --extra-config-opt=format.generaldelta=1
This reduces the amount of noise introduced by the debugindex command,
the main source of differences. In my environment, when testing with
generaldelta enabled, this change reduces the number of completely
failing tests from 21 to 8.
This gcc option has been deprecated since at least 2009 (gcc 4.4),
and it causes compilations to fail entirely with gcc 4.6.x.

Most uses of templates requires a trailing newline to get vertical output.
Graphlog with a template without trailing newline did however not just create
horisontal output like other commands would but truncated the output at the
last \n. Template values without any \n were ignored completely.
Graphlog will now only eat one trailing newline before it lets the flow of the
graph add the necessary vertical space.
Changeset detected as obsolete will be displayed as "x" instead of 'o':
o new rewritten changeset
|
| x old obsolete changeset
|/
|
o base
This will be useful even when some obsolete changeset will be "hidden" because
not all obsolete changeset can be hidden. If an obsolete changeset have
non-obsolete descendant we can't simply hide it. And having a clear visual hint
that the changeset is obsolete is useful.
The main reason to make this minor change right now is to:
1) introduce an officiel user of the `ctx.obsolete()` method that will detect
breakage earlier than third party code (mutable, hgview)
2) Do not display any vocabulary related to obsolete. Such vocabulary will
require discussion.
Since chmod isn't supported on Windows (or vfat), I'm importing a here-doc
instead (<<EOF ..).
Option --bypass on import of the here-doc is required on Windows (or vfat) to
bypass the working directory (see hg help import). Not using --bypass would
lose the mode changing bits.
I've had to insert a --bypass on the preexisting import call futher down in the
test, because importing a patch with --exact and mode changes will fail on
Windows (and vfat).
As the point of this test is not to test commit, I'm using the import
procedure for all platforms unconditionally, that is, I'm intentionally not
keeping the original sequence of hg and chmod calls for platforms that support
exec either, which saves us having to insert an #if exec ... #else ... #endif.
