Before this patch, external editor process for the commit log can't
view some in-memory changes (especially, of dirstate), because they
aren't written out until the end of transaction (or wlock).
This causes unexpected output of Mercurial commands spawned from that
editor process.
To make in-memory changes visible to external editor process, this
patch does:
- write (or schedule to write) in-memory dirstate changes, and
- set HG_PENDING environment variable, if:
- a transaction is running, and
- there are in-memory changes to be visible
"hg diff" spawned from external editor process for "hg qrefresh"
shows:
- "changes newly imported into the topmost" before ab68b153ce34(*)
- "all changes recorded in the topmost by refreshing" after this patch
(*) ab68b153ce34 changed steps invoking editor process
Even though backward compatibility may be broken, the latter behavior
looks reasonable, because "hg diff" spawned from the editor process
consistently shows "what changes new revision records" regardless of
invocation context.
In fact, issue4378 itself should be resolved by b46029eb5b29, which
made 'repo.transaction()' write in-memory dirstate changes out
explicitly before starting transaction. It also made "hg qrefresh"
imply 'dirstate.write()' before external editor invocation in call
chain below.
- mq.queue.refresh
- strip.strip
- repair.strip
- localrepository.transaction
- dirstate.write
- localrepository.commit
- invoke external editor
Though, this patch has '(issue4378)' in own summary line to indicate
that issues like issue4378 should be fixed by this.
BTW, this patch adds '-m' option to a 'hg ci --amend' execution in
'test-commit-amend.t', to avoid invoking external editor process.
In this case, "unsure" states may be changed to "clean" according to
timestamp or so on. These changes should be written into pending file,
if external editor invocation is required,
Then, writing dirstate changes out breaks stability of test, because
it shows "transaction abort!/rollback completed" occasionally.
Aborting after editor process invocation while commands below may
cause similar instability of tests, too (AFAIK, there is no more such
one, at this revision)
- commit --amend
- without --message/--logfile
- import
- without --message/--logfile,
- without --no-commit,
- without --bypass,
- one of below, and
- patch has no description text, or
- with --edit
- aborting at the 1st patch, which adds or removes file(s)
- if it only changes existing files, status is checked only for
changed files by 'scmutil.matchfiles()', and transition from
"unsure" to "normal" in dirstate doesn't occur (= dirstate
isn't changed, and written out)
- aborting at the 2nd or later patch implies other pending
changes (e.g. changelog), and always causes showing
"transaction abort!/rollback completed"
The current output for a failed merge with conflict markers looks something like:
merging foo
warning: conflicts during merge.
merging foo incomplete! (edit conflicts, then use 'hg resolve --mark')
merging bar
warning: conflicts during merge.
merging bar incomplete! (edit conflicts, then use 'hg resolve --mark')
We're going to change the way merges are done to perform all premerges before
all merges, so that the output above would look like:
merging foo
merging bar
warning: conflicts during merge.
merging foo incomplete! (edit conflicts, then use 'hg resolve --mark')
warning: conflicts during merge.
merging bar incomplete! (edit conflicts, then use 'hg resolve --mark')
The 'warning: conflicts during merge' line has no context, so is pretty
confusing.
This patch will change the future output to:
merging foo
merging bar
warning: conflicts while merging foo! (edit, then use 'hg resolve --mark')
warning: conflicts while merging bar! (edit, then use 'hg resolve --mark')
The hint on how to resolve the conflicts makes this a bit unwieldy, but solving
that is tricky because we already hint that people run 'hg resolve' to retry
unresolved merges. The 'hg resolve --mark' mostly applies to conflict marker
based resolution.
Before this patch, template keywords `{file_mods}`, `{file_adds}` and
`{file_dels}` use values gotten by `repo.status(ctx.p1().node(),
ctx.node())`.
But this doesn't work as expected if `ctx` is `memctx` or
`workingcommitctx`. Typical case of templating with these contexts is
customization of the text shown in the commit message editor by
`[committemplate]` configuration.
In this case, `ctx.node()` returns None and it causes comparison
between `ctx.p1()` and `workingctx`. `workingctx` lists up all changed
files in the working directory even at selective committing.
BTW, `{files}` uses `ctx.files()` and it works as expected.
To compare target context and its parent exactly, this patch passes
`ctx.p1()` and `ctx` without `node()`-nize. This avoids unexpected
comparison with `workingctx`.
This patch uses a little redundant template configurations in
`test-commit.t`, but they are needed to avoid regression around
problems fixed by 17e2fda16f58 and 2b999bc2d89a: accessing on `ctx`
may break `ctx._status` field.
The phase of the pending commit depends on the parent of the working directory
and on the phases.newcommit configuration.
First, this information rather depend on the commit line which describe the
pending commit.
Then, we only want to be advertised when the pending phase is going to be higher
than the default new commit phase.
So the format will change from
$ hg summary
parent: 2:ab91dfabc5ad
foo
parent: 3:24f1031ad244 tip
bar
branch: default
commit: 1 modified, 1 unknown, 1 unresolved (merge)
update: (current)
phases: 1 secret (secret)
to
parent: 2:ab91dfabc5ad
foo
parent: 3:24f1031ad244 tip
bar
branch: default
commit: 1 modified, 1 unknown, 1 unresolved (merge) (secret)
update: (current)
phases: 1 secret
This warning exists to prevent git users from prematurely polluting
their namespace when trying out Mercurial. But for repos that already
have multiple branches, understanding what branches are is not
optional so we should just shut up.
The number of draft and secret changesets are currently not summarized.
This is an important information because the number of drafts give some rough
idea of the number of outgoing changesets in typical workflows, without needing
to probe a remote repository. And a non-zero number of secrets means that
those changeset will not be pushed.
If the repository is "dirty" - some draft or secret changesets exists - then
summary will display a line like:
phases: X draft, Y secret (public)
The phase in parenthesis corresponds to the highest phase of the parents of
the working directory, i.e. the current phase.
By default, the line is not printed if the repository is "clean" - all
changesets are public - but if verbose is activated, it will display:
phases: (public)
On the other hand, nothing will be printed if quiet is in action.
A few tests have been added in test-phases.t to cover the -v and -q cases.
Before this change, amending a merge would lose the rename information for file
adding in the second parents and implicitly renamed into a new directory.
In case of the merge, we also look for directory rename data from the second
parent. This seems to fix the bug and does not show other issues from the test
suite.
Previously, a backup bundle could overwrite an existing bundle and cause user
data loss. For instance, if you have A<-B<-C and strip B, it produces backup
bundle B-backup.hg. If you then hg pull -r B B-backup.hg and strip it again, it
overwrites the existing B-backup.hg and C is lost.
The fix is to add a hash of all the nodes inside that bundle to the filename.
Fixed up existing tests and added a new test in test-strip.t
commitctx already showed notes with filenames but didn't provide any context.
It is just as relevant to know when manifest or changelog is committed.
So, in addition to filenames, also show headlines 'committing files:',
'committing manifest' and 'committing changelog'.
This is kind of similar to the debugbundle command but gives summarized actual
uncompressed number of bytes when creating the bundle. The numbers are as
usable as the bundle format is efficient. Hopefully bundle2 will make it a
better indicator of actual entropy.
This is useful when accepting pull requests to assess whether the repo size
increase seems reasonable for the diff before pushing stuff upstream, It has
helped me catching large files that should have been committed as largefiles
but was committed as regular files in intermediate changesets.
This output doesn't combine well with debug output so we only enable it when
verbose without debug.
Before this patch, "memctx._manifest" tries to get (and use normally)
filectx also for newly-removed files, even though "memctx.filectx()"
returns None for such files.
To calculate manifest correctly even with newly-removed files, this
patch does:
- replace "man.iteritems()" for the loop by "self._status.modified"
to avoid accessing itself to newly removed files
this also reduces loop cost for large manifest.
- remove files in "self._status.removed" from the manifest
In this patch, amending is confirmed twice to examine both (1) newly
removed files and (2) ones already removed in amended revision.
Before this patch, "memctx._manifest" calculates the manifest
according to the 1st parent. This causes the disappearance
of newly added files from the manifest.
For example, if newly added files aren't listed up in manifest of
memctx, they aren't listed up in "added" field of "status" returned by
"ctx.status()", and "{diff()}" (= "patch.diff") in "committemplate"
shows nothing for them.
To calculate manifest including newly added files correctly, this
patch puts newly added files (= ones in "self._status.added") into the
manifest.
Some details of changes for "test-commit-amend.t" in this patch:
- "touch foo" is replaced by "echo foo > foo", because newly added
empty file can't be shown in "diff()" output without "diff.git"
configuration
- amending is confirmed twice to examine both (1) newly added files
and (2) ones already added in amended revision
Before this patch, "memctx._status" is initialized by "(files, [], [],
[], [], [], [])" and this causes "memctx.modified" to include not
only modified files but also added and removed ones incorrectly.
This patch adds "_status" method to calculate exact status being
committed according to "files" specified at construction time.
Exact "_status" is useful to share/reuse logic of committablectx.
This patch is also preparation for issues fixed by subsequent patches.
Some details of changes for tests in this patch:
- some filename lines are omitted in "test-convert-svn-encoding.t",
because they are correctly listed up as "removed" files
those lines are written out in "localrepository.commitctx" for
"modified" and "added" files by "ui.note".
- "| fixbundle" filterring in "test-histedit-fold.t" is omitted to
check lines including "added" correctly
"fixbundle" discards all lines including "added".
Show status messages with first line of commit description and names, like
grafting 12:2647734878ef "fork" (tip)
This gives more context for the user when resolving conflicts.
This addresses the bug described in issue4405: when obsolescence markers are
enabled, amending a commit with a file move can lead to the copy information
being lost.
However, the bug is more general and can be reproduced without obsmarkers as
well, as demonstracted by Pierre-Yves and put into the updated test.
Specifically, graph topology divergences between the filelogs and the changelog
can cause copy information to be lost during amends.
This test actually used the obs.py file as part of the test, so we need to fix
up the test a little more than usual to work with the new obsolete option flags.
"editform" argument for "getcommiteditor" is decided according to the
format below:
COMMAND[.ROUTE]
- COMMAND: name of command
- ROUTE: name of route, if there are two or more routes in COMMAND
This patch uses "amend.normal" and "amend.merge" as ROUTE of
"editform" instead of "amend", to distinguish merge commits from other
in "hg commit --amend" case.
We already have a ":" after the user name to denote the start of the
description. The current usage of quotes around the description is
problematic as the truncation to 80 chars is likely to drop the
closing quote. This may confuse syntax coloration in some editors.
Adds a conflict marker formatter that can produce custom conflict marker
descriptions. It can be set via ui.mergemarkertemplate. The old behavior
can be used still by setting ui.mergemarkers=basic.
The default format is similar to:
{node|short} {tag} {branch} {bookmarks} - {author}: "{desc|firstline}"
And renders as:
contextblahblah

The recently introduced message was:
no unresolved files; you may continue your unfinished operation
This had three problems:
- looks a bit like an error message because it's not saying "we've
just resolved the last file"
- refers to "unfinished operation", which won't be the case with
"update" or "merge"
- introduces semicolons to error messages, which is stylistically
questionable
I've simplified this to:
no more unresolved files
In the future, if we want to prompt someone to continue a particular operation, we should use
a hint style:
no more unresolved files
(use 'hg graft --continue' to finish grafting)
When using resolve, users often have to consult with the output of |hg
resolve -l| to see if any unresolved files remain. This step is tedious
and adds overhead to resolving.
This patch will notify a user if there are no unresolved files remaining
after executing |hg resolve|::
no unresolved files; you may continue your unfinished operation
The patch stops short of telling the user exactly what command should be
executed to continue the unfinished operation. That is because this
information is not currently captured anywhere. This would make a
compelling follow-up feature.
1fc59036a99b introduces "--edit" option into "hg commit", but it
doesn't work for "hg commit --amend", because 1fc59036a99b prepares
for editor invocation only around "commitfunc()" internal function,
which is used only for temporary amend commit by "cmdutil.amend()".
Actual commit message editing is executed in "cmdutil.amend()".
This patch invokes editor forcibly when "--edit" option is specified
for "hg commit --amend", even if commit message is specified
explicitly by "--message" or "--logfile".
This patch also removes useless handling for commit message and editor
invocation around "commitfunc()" internal function.
Before this patch, commit message (may be manually edited) for "commit
--amend" is never saved into ".hg/last-message.txt", because it uses
"localrepository.commitctx()" instead of "localrepository.commit()":
saving into ".hg/last-message.txt" is executed only in the latter.
This patch saves commit message for "commit --amend" into
".hg/last-message.txt" just after user editing.
This is the simplest implementation to fix on stable. Editing and
saving commit message for memctx should be centralized into the
framework like "localrepository.commit()" with "editor" argument or so
in the future.
Before this patch, "hg commit --amend --secret" doesn't create new
amend changeset as secret, even though the internal function
"commitfunc()" passed to "cmdutil.amend()" make "phases.new-commit"
configuration as "secret" temporarily.
"cmdutil.amend()" uses specified "commitfunc" only for temporary amend
commit, and creates the final amend commit changeset by
"localrepository.commitctx()" directly with memctx.
This patch creates new amend changeset as secret correctly for
"--secret" option, by changing "phases.new-commit" configuration
temporarily before "localrepository.commitctx()".
You can't close a branch that hasn't got a head.
newbranch + commit --close-branch must fail
newbranch + commit + commit --amend --close-branch must fail
You must not be allowed to close a branch that is not defined.
The `ui.prevent-unstable` option never made it into core. It always behaves
this way when obsolescence feature is enabled.
See changesets caaf2a66c719, f111507ae88a and 51dfebaadebc for details.
The dispatch code now enables filtering of "hidden" changesets globally. The
filter is installed before command and extension invocation. The `--hidden`
switch is now global and disables this filtering for any command.
Code in log dedicated to changeset exclusion is removed as this global filtering
has the same effect.
The active bookmark were moved to the temporary commit. When the transaction
were rollbacked, the bookmark were lost.
We now temporarly disable the bookmark to prevent this effect.
The temporary commit created by amend update the dirstate. If the final commit
fails, we need to invalidate the change made to the dirstate, otherwise the
release of the wlock will write the dirstate created after the rollbacked
temporary commit.
This dirstate writing logic should probably be handled in the same object than
the transaction one. However such change are too big for stable.
Obsolescence marker can represent this situation just fine. The old
version is marked as precursor of the new changeset. All its
descendants become "unstable".
If obsolescence is not enabled we keep the current behavior of
aborting. This new behavior only applies when obsolete is
enabled and is subject to future discussion and changes.
Obsolescence cycle are bad and should be avoided as much as possible. The
current amend implemented touch changeset meta data as few as possible. This
make is easy for amend to result in the same node than a precursors. We add some
deterministic noise in extra to avoid this. In practice, the hex of the amended
changeset is stored in 'amend_source' extra key.
Before this changeset, the extra commit created during amend had
the same description as the final commit. This was a bit confusing
when trying to understand what that extra commit was about.
This changeset changes the description of such commit to:
temporary amend commit for <ammend-commit-hash>
The old behaviour was not a big deal, but would become more confusing
once we use obsolescence marker instead of stripping the precursors.
This also helps if the user restores a strip backup.
Some shells, e.g. ksh89, will emit \" in a here document as ",
while others will emit \". To be sure of getting \", we specify \\".
This gets test-commit-amend.t and test-largefiles.t working on AIX.
New commit from the amend process were created without any phase contraint. If
the amended changeset had a different phase from it's parent, the phases data
were lost.
The changeset ensure the new commit are created in the same phase than the
original changeset.
