We could create a patch of such name, but it wouldn't be processed properly
by mq as parseseries() strips leading/trailing whitespace.
The test of default message (added by 063a2c623014) is no longer be useful
so removed.
This issue was reported as:

Since we are introducing obs-based shelve, we are no longer
stripping temporary nodes, we are obsoleting them. Therefore
it looks like stipnodes would be a misleading name, while
prune has a connotaion of "strip but with obsolescense", so
nodestoprune seems like a good rename.
Obsolescense-based shelve only needs metadata stored in .hg/shelved
and if feels that this metadata should be stored in a
simplekeyvaluefile format for potential extensibility purposes.
I want to avoid storing it in an unstructured text file where
order of lines determines their semantical meanings (as now
happens in .hg/shelvedstate. .hg/rebasestate and I suspect other
state files as well).
Not included in this series, I have ~30 commits, doubling test-shelve.t
in size and testing almost every tested shelve usecase for obs-shelve.
Here's the series for the curious now: http://pastebin.com/tGJKx0vM
I would like to send it to the mailing list and get accepted as well,
but:
1. it's big, so should I send like 6 patches a time or so?
2. instead of having a commit per test case, it more like
a commit per some amount of copy-pasted code. I tried to keep
it meaningful and named commits somewhat properly, but it is
far from this list standards IMO. Any advice on how to get it
in without turning it into a 100 commits and spending many
days writing descriptions?
3. it makes test-shelve.t run for twice as long (and it is already
a slow test). Newest test-shelve.r runs for ~1 minute.
Move "cleanupnode" (unsafe strip) into "safecleanupnode" so it's impossible
to call the unsafe function directly.
This helps reduce future programming errors.
The new method will decide between:
- cleanupnode, which calls the unsafe repair.strip
- create obsmarkers
Ideally, nobody calls "cleanupnode" directly except for "safecleanupnode".
Recently we switched rebases to run the entire rebase inside a single
transaction, which dramatically improved the speed of rebases in repos with
large working copies. Let's also move the dirstate into a single dirstateguard
to get the same benefits. This let's us avoid serializing the dirstate after
each commit.
In a large repo, rebasing 27 commits is sped up by about 20%.
I believe the test changes are because us touching the dirstate gave the
transaction something to actually rollback.
This adds an option (which defaults to False) to run entire histedits in a
single transaction. This results in 20-25% faster histedits in large repos where
transaction startup cost is expensive.
I didn't want to enable this by default because it has some unfortunate side
effects. For instance, if a pretxncommit hook throws midway through the
histedit, it will rollback the entire histedit and lose any progress the user
had made. Same if the user aborts editting a commit message. It's still worth
turning this on for large repos, but probably not for normal sized repos.
Long term, once we have inmemory merging, we could do the entire histedit in
memory, without a transaction, then we could selectively rollback just parts of
it in the event of an exception.
Tested it by running the tests with
`--extra-config-opt=histedit.singletransaction=True`. The only failure was
related to the hook rollback issue I mention above.
We only want to pop the action after the action is completed, since if the
action aborts part way through we want it to remain at the front of the list so
continue/abort will start with it.
Previously we relied on the fact that we only serialized the state file at the
beginning of the action, so the pop wasn't serialized until the next iteration
of the loop. In a future patch we will be adding a large transaction around this
area, which means if we pop the list early it might get serialized if the action
throws a user InterventionRequired error, at which point the action is not in
the list anymore. So let's only pop it once the action is really truly done.
Changeset 97936471dc8d removed the mutable default value, but did not explicitly

issue. We move to an explicit testing for None as recommended by PEP8:

This patch makes us respect pager.attend again if the extension is
enabled. It also brings back the default attend list, so e.g. summary
is not paged by default, just like it used to be before pager was
moved into core.
The named branch of the leaf changeset can be changed by updating to it,
setting the branch, and amending.
But previously, there was no good way to *just* change the branch of several
linear changes. If rebasing changes with another parent to '.', it would pick
up a pending branch change up. But when rebasing changes that have the same
parent, it would fail with 'nothing to rebase', even when the branch name was
set differently.
To fix this, allow rebasing to same parent when a branch has been set.
By including the working directory revision at the start of rebase in
the repo._rebaseset, we make sure it's not hidden when we update back
to it at the end of the rebase.
This feels like abusing the set a bit given its name (_rebaseset), but
I couldn't think of another name that's clearly better.
Now that the 'vfs' classes moved in their own module, lets use the new module
directly. We update code iteratively to help with possible bisect needs in the
future.

Previously, rebasing would open several transaction over the course of rebasing
several commits. Opening a transaction can have notable overhead (like copying
the dirstate) which can add up when rebasing many commits.
This patch adds a single large transaction around the actual commit rebase
operation, with a catch for intervention which serializes the current state if
we need to drop back to the terminal for user intervention. Amazingly, almost
all the tests seem to pass.
On large repos with large working copies, this can speed up rebasing 7 commits
by 25%. I'd expect the percentage to be a bit larger for rebasing even more
commits.
There are minor test changes because we're rolling back the entire transaction
during unexpected exceptions instead of just stopping mid-rebase, so there's no
more backup bundle. It also leave an unknown file in the working copy, since our
clean up 'hg update' doesn't delete unknown files.
Previously, if .hg/rebasestate existed but .hg/last-message.txt was missing, 'hg
rebase --abort' would say there's no rebase in progress but 'hg checkout foo'
would say 'abort: rebase in progress'. It turns out loading the collapse message
will throw a "no rebase in progress" error if the file doesn't exist, even
though .hg/rebasestate obviously indicates a rebase is in progress.
The fix is to only throw an exception if we're trying to --continue, and to just
eat the issues if we're doing --abort.
This issue is exposed by us writing the rebase state earlier in the process.
This will be used by later patches to ensure the user can appropriately 'hg
rebase --abort' if there's a crash before the first the first commit has
finished rebasing. Tests cover all of this. The only negative affect is we now
require a hg rebase --abort in a very specific exception case, as shown in the
test.
The rebaseruntime class already has the restorestatus function, so let's make it
own the store status function too. This get's rid of a lot of unnecessary
argument passing and will make a future patch cleaner that refactors storestatus
to support transactions.
Previously, rebase --abort would only call update if you were on a node that had
already been rebased. This meant that if the rebase failed during the rebase of
the first commit, the working copy would be left dirty (with a .hg/updatestate
file) and rebase --abort would not have update to clean it up.
The fix is to also perform an update if you're still on the target node or on
the original working copy node (since the working copy may be dirty, we still
need to do the update). We don't want to perform an update in all cases though
because of issue4009.
A subsequent patch makes this case much more common, since it causes the entire
rebase transaction to rollback during unexpected exceptions. This causes the
existing test-rebase-abort.t to cover this case.
This can be used to flag patches by branch or topic automatically. Flags
optionally given by --flag option are exported as {flags} template keyword,
so you can add --flag V2.
I want to move _getpatches() to _getpatchmsgs() to make sure each patch text
is tied with the corresponding revision number. This helps adding templater
support.
IIRC, the pbranch extension doesn't work with the recent Mercurial versions,
so the removal of this option wouldn't hurt.
Storing a relative path the source repository is useful when exporting
repositories over the network or when they're located on external
drives where the mountpoint isn't always fixed.
Currently, Mercurial interprets paths in `.hg/shared` relative to
$PWD. I suspect this is very much unintentional, and you have to
manually edit `.hg/shared` in order to trigger this behaviour.
However, on the off chance that someone might rely on it, I added a
new capability called 'relshared'. In addition, this makes earlier
versions of Mercurial fail with a graceful error.
I should note that I haven't tested this patch on Windows.
Now that the feature no longer lives in the extension, we document it in the
help of the core config. This include the new 'ui.color' option introduced in
the previous changesets.
As a result the color extensions can now be deprecated.
This is a documentation patch only; color is still disabled by default.
This is the last bits we needed to move out of the extensions. 'hgext/color.py'
now only contains logic to changes the default color behavior to 'auto'.
However, more cleanups are on the way and we need to document the new config
directly in core.
We've made chg utilize the common code path implemented in pager.py (by
e8fb65f5e551 and e97133c7a9dc), but the chg server does not always start
with a tty. Because of this, uisetup() of the pager extension could be
skipped on the chg server.
Kudos given to Sean Farley for dogfooding new chg and spotting this problem.
This patch makes it possible to unshelve while having missing files
in your repo as long as shelved changes don't touch those missing files.
It also makes error message better otherwise.
Before this patch, there was a single way to see multiple shelves using
`--patch --list` which show all the shelves. Doing `--patch s1 s2` returns an
error. This patch allows to show multiple shelves using `--patch` and `--stat`.
pycompat.getenv returns os.getenvb on py3 which is not available on Windows.
This patch replaces them with encoding.environ.get and checks to ensure no
new instances of os.getenv or os.setenv are introduced.
When converting a Git repository to Mercurial at Mozilla, I encountered
a scenario where I didn't want `hg convert` to automatically add the
"committer: <committer>" line to commit messages. While I can hack around
this by rewriting the Git commit before it is fed into `hg convert`,
I figured it would be a useful knob to control.
This patch introduces a config option that allows lots of control
over the committer value. I initially implemented this as a single
boolean flag to control whether to save the committer message. But
then there was feedback that it would be useful to save the committer
in extra data. While this patch doesn't implement support for saving
in extra data, it does add a mechanism for extending which actions
to take on the committer field. We should be able to easily add
actions to save in extra data.
Some of the implemented features weren't asked for. But I figured they
could be useful. If nothing else they demonstrate the extensibility
of this mechanism.
Detailed hint message is now provided when 'pull --rebase' operation detects
unclean working dir, for example:
abort: uncommitted changes
(cannot pull with rebase: please commit or shelve your changes first)
Added tests for uncommitted merge, and for subrepo support verifying that same
hint is also passed to subrepo state check.
Since chg has its own _runpager implementation, it's no longer necessary to
special-case chg in the pager extension. This will effectively enable the
new chg pager code path that runs inside runcommand.
Refuse to run 'hg pull --rebase' if there are uncommitted changes:
so that instead of going ahead with fetching changes and then suddenly aborting
the rebase, we can warn user of uncommitted changes (or unclean repo state)
right up front.
In tests, we create a 'histedit' session to verify that also an unfinished
state is detected and handled.
As discussed at [1], ui._runpager will be the new low-level API accepting a
pager command to actually run the pager. And ui.pager is the high-level API
which reads config directly from self.
This change is necessary for chgserver to override _runpager cleanly.

This dictionnary is affected by the content of the config, so we should have
one for each ui config.
We rename the global dict to '_baseterminfoparams' to make the situation
clearer.
This new option control whether or not color will be used. It mirror the behavior
of '--color'. I usually avoid adding new option to '[ui]' as the section is
already filled with many option. However, I feel like 'color' is central enough
to deserves a spot in this '[ui]' section.
For now the option is not documented so it is still marked as experimental. Once
it get documented and official, we should be able to deprecate the color
extensions.
There is more cleanup to do before that documentation is written, but we need
this option early to made them. Having that option will allow for more cleanup
of the initialisation process and proper separation between color
configuration.
We now run the color initialisation as part of the standard dispatch. This is
opening the way for multiple cleanups since we now have access to the multiple 'ui'
object and we'll be able to see difference between global and local config. This
cleanup will arrive in later changesets.
As a side effect, the '--color' flag is now working without the extension.
Since we now properly initialize color for each ui idependently, we get a
warning message twice.
If we want to be able to move the initialisation in core, we need core to be
aware of that '--color' flag at all time. So we now have the definition in core. That flag
is currently unprocessed without the extensions (will be fixed soon). In
addition the default value for this flag in core is 'never'. Enabling the
extensions change that default value to 'auto'.
If 'ui.plain()' is set we should not colorize. We move that logic into the
function that determine and setup the color mode. As all other code respect
the resulting mode this will be equivalent.
