Before this patch, filemerge slices byte sequence directly to trim
conflict markers, but this may cause:
- splitting at intermediate multi-byte sequence
- incorrect calculation of column width (length of byte sequence is
different from columns in display in many cases)
This patch uses 'util.ellipsis' to trim custom conflict markers
correctly, even if multi-byte characters are used in them.
Before this patch, with careless configuration (missing '|firstline'
filtering for '{desc}' keyword, for example), '[ui]
mergemarkertemplate' can make conflict markers multiple lines.
For ordinary users, advantage of allowing '[ui] mergemarkertemplate'
to generate multiple lines for customizing seems to be less than
advantage of disallowing it for safety.
This patch uses only the first line of the conflict marker generated
from '[ui] mergemarkertemplate' configuration for safety.
Before this patch, 'progress' extension applies 'len' on byte sequence
to get column width of it, but it causes incorrect result, when length
of byte sequence and columns in display are different from each other
in multi-byte characters.
This patch uses 'encoding.colwidth' to get column width of items in
output line correctly, even if it contains multi-byte characters.
Before this patch, 'progress' extension trims items in output line by
directly slicing byte sequence, but it may split at intermediate
multi-byte sequence.
This patch uses 'encoding.trim' to trim items in output line
correctly, even if it contains multi-byte characters.
Before this patch, 'progress' extension applies 'len' on byte sequence

This patch uses 'encoding.trim' to trim output line correctly, even if
it contains multi-byte characters.
"rm -f loop.pyc" before changing "loop.py" in "test-progress.t"
ensures that re-compilation of "loop.py", even if "loop.py" and
"loop.pyc" have same timestamp in seconds.
Before this patch, trimming description of each changesets in histedit
may split at intermediate multi-byte sequence.
This patch uses 'util.ellipsis' to trim description of each changesets
instead of directly slicing byte sequence.
Even though 'util.ellipsis' adds '...' as ellipsis when specified
string is trimmed (= this changes result of trimming), this patch uses
it, because:
- it can be used without any additional 'import', and
- ellipsis seems to be better than just trimming, for usability
This option had very limited utility and counterintuitive behavior and
collided unfortunately with the much later -B option.
Normally we would no-op such a feature so as to avoid annoying existing
scripts. However, we have to weigh that against the silent misbehavior
that results when users mistakenly intended to use -B: because -b
takes no arg, the bookmark gets interpreted as a normal revision, and
gets stripped without removing the associated bookmark, while also not
backing up the revision in question. A no-op behavior or warning would only
remove the latter half of the misadventure.
The only users I can find of this feature were using it in error and
have since stopped. The few (if any) remaining users of this feature
would be better served by --no-backup.
The defect was that copies were always duplicated against the target
revision, rather than the first parent of the revision being
rebased. This produced nominally correct results if changes were
rebased one at a time (or with --collapse), but was wrong if we
rebased a sequence of changesets which contained a sequence of copies.
This fixes a crash that may happen when using mercurial 3.0.x.
The _gethiddenblockers function assumed that the output of tags.readlocaltags()
was a dict mapping tags to of valid nodes. However this was not necessarily the
case. When a repository had obsolete revisions and had local tag pointing to a
non existing revision was found, many mercurial commands would crash.
This revision fixes the problem by removing any tags from the output of
tags.readlocaltags() which point to invalid nodes.
We may want to add a warning when this happens (although it might be
annoying to get that warning for every command, possibly even more than once per
command).
A test for this problem has been added to test-obsolete.t. Without this fix the
test would output:
$ hg tags
abort: 00changelog.i@3816541e5485: no node!
[255]
Instead of:
$ hg tags
tiptag 2:3816541e5485
tip 2:3816541e5485
visible 0:193e9254ce7e
Previously, a glob pattern of the form 'foo/**/bar' would match 'foo/a/bar' but
not 'foo/bar'. That was because the '**' in 'foo/**/bar' would be translated to
'.*', making the final regex pattern 'foo/.*/bar'. That pattern doesn't match
the string 'foo/bar'.
This is a bug because the '**/' glob matches the empty string in standard Unix
shells like bash and zsh.
Fix that by making the ending '/' optional if an empty string can be matched.
Before this patch, 'hg fetch' may cause unexpected conflict, if 'hg
fetch'-ed changes are located near lines in which keywords are
embedded, because keywords are substituted with other strings in the
working directory.
This patch suppresses keyword expansion while 'hg fetch' for internal
merge by adding 'fetch' to 'restricted' command list like 'merge'.
This patch uses 'hg import' to safely create the new head to be merged
at succeeding 'hg fetch', because:
- branch of revision #10 is different from one of #11 in 'Test'
repository, so just 'hg fetch -r 11' doesn't cause merging between
them
this means the new head should be created manually.
- 'hg import' is easier and safer than 'cat <<EOF' and 'hg commit'
to replay same changes including special characters like '$'
safeness of 'hg import' with keyword extension is already examined
in 'test-keyword.t'.
Before this patch, 'hg histedit' may cause unexpected conflict, if 'hg
histedit'-ed changes are located near lines in which keywords are
embedded, because keywords are substituted with other strings in the
working directory.
This patch suppresses keyword expansion while 'hg histedit' for
internal merge by adding 'histedit' to 'restricted' command list like
'merge'.
Test in this patch just swaps order of revision #13 and #14: this is
enough to cause internal merge.
Before this patch, 'hg backout' may cause unexpected conflict, if 'hg
backout'-ed changes are located near lines in which keywords are
embedded, because keywords are substituted with other strings in the
working directory.
This patch suppresses keyword expansion while 'hg backout' for
internal merge by adding 'backout' to 'restricted' command list like
'merge'.
Before this patch, 'hg graft' may cause unexpected conflict, if 'hg
graft'-ed changes are located near lines in which keywords are
embedded, because keywords are substituted with other strings in the
working directory.
This patch suppresses keyword expansion while 'hg graft' for internal
merge by adding 'graft' to 'restricted' command list like 'merge'.
Before this patch, 'hg rebase' may cause unexpected conflict, if 'hg
rebase'-ed changes are located near lines in which keywords are
embedded, because keywords are substituted with other strings in the
working directory.
This patch suppresses keyword expansion while 'hg rebase' for internal
merge by adding 'rebase' to 'restricted' command list like 'merge'.
This patch specifies '--keep' to 'hg rebase', because revision #10 is
useful also for tests in succeeding patches.
Before this patch, 'hg unshelve' may cause unexpected conflict, if 'hg
unshelve'-ed changes are located near lines in which keywords are
embedded, because keywords are substituted with other strings in the
working directory.
This patch suppresses keyword expansion while 'hg unshelve' for
internal merge by adding 'unshelve' to 'restricted' command list like
'merge'.
When bundle2 was enabled, if hg pull had no commits to pull, it would print
'no changes found' and then download the entire repository from the server. This
was caused by heads and common being set to None, which gets treated as
heads=cl.heads() and common=[nullid], which means download the entire repo.
Pulling bundles without a changegroup is a valid use case (like if we're just
updating bookmarks), so this modifes the bundle code to allow not adding
changegroups.
This is backport of 26ad3517a3a2.
No command should fail with ValueError just because there is unparseable
alias definition.
It returns 1 like other badalias handlers, but should be changed to 255 in
a later version because we use 255 for general command error.
Before this patch, "reporelpath()" uses "rstrip(os.sep)" to trim
"os.sep" at the end of "parent.root" path.
But it doesn't work correctly with some problematic encodings on
Windows, because some multi-byte characters in such encodings contain
'\\' (0x5c) as the tail byte of them.
In such cases, "reporelpath()" leaves unexpected '\\' at the beginning
of the path returned to callers.
"lcalrepository.root" seems not to have tail "os.sep", because it is
always normalized by "os.path.realpath()" in "vfs.__init__()", but in
fact it has tail "os.sep", if it is a root (of the drive): path
normalization trims tail "os.sep" off "/foo/bar/", but doesn't trim
one off "/".
So, just avoiding "rstrip(os.sep)" in "reporelpath()" causes
regression around issue3033 fixed by e3dfde137fa5.
This patch introduces "pathutil.normasprefix" to normalize specified
path in the specific way for problematic encodings without regression
around issue3033.
Before this patch, sanitizing ".hg/hgrc" scans directories and files
also in meta data area for non-hg subrepos: under ".svn" for
Subversion subrepo, for example.
This may cause not only performance impact (especially in large scale
subrepos) but also unexpected removing meta data files.
This patch avoids sanitizing ".hg/hgrc" in meta data area for non-hg
subrepos.
This patch stops checking "ignore" target at the first
(case-insensitive) appearance of it, because continuation of scanning
is meaningless in almost all cases.
Before this patch, "hg update" doesn't sanitize ".hg/hgrc" in non-hg
subrepos correctly, if "hg update" is executed not at the root of the
parent repository.
"_sanitize()" takes relative path to subrepo from the root of the
parent repository, and passes it to "os.walk()". In this case,
"os.walk()" expects CWD to be equal to the root of the parent
repository.
So, "os.walk()" can't find specified path (or may scan unexpected
path), if CWD isn't equal to the root of the parent repository.
Non-hg subrepo under nested hg-subrepos may cause same problem, too:
CWD may be equal to the root of the outer most repository, or so.
This patch makes "_sanitize()" take absolute path to the root of
subrepo to sanitize correctly in such cases.
This patch doesn't normalize the path to hostile files as the one
relative to CWD (or the root of the outer most repository), to fix the
problem in the simple way suitable for "stable".
Normalizing should be done in the future: maybe as a part of the
migration to vfs.
Before this patch, sanitizing ".hg/hgrc" in git subrepo doesn't work,
when the working directory is updated by "git merge --ff".
"_sanitize()" is not invoked after checking target revision out into
the working directory in this case, even though it is invoked
indirectly via "checkout" (or "rawcheckout") in other cases.
This patch invokes "_sanitize()" explicitly also after "git merge
--ff" execution.
"_sanitize()" was introduced by 5131f2755f60 on "stable" branch, but
it has done nothing for sanitizing since 5131f2755f60.
"_sanitize()" assumes "Visitor" design pattern:
"os.walk()" should invoke specified function ("v" in this case)
for each directory elements under specified path
but "os.walk()" assumes "Iterator" design pattern:
callers of it should drive loop to scan each directory elements
under specified path by themselves with the returned generator
object
Because of this mismatching, "_sanitize()" just discards the generator
object returned by "os.walk()" and does nothing for sanitizing.
This patch makes "_sanitize()" work.
This patch also changes the format of warning message to show each
unlinked files, for multiple appearances of "potentially hostile
.hg/hgrc".
This also includes test for shell aliases. It avoid using "false" command
because "man false" does not say "exit with 1" but "exit with a status code
indicating failure."
Python on Windows apparently use encoded stream by default. We use the same
trick than elsewhere in the code to make them binary.
This should fix the current buildbot failure on windows.
Previously the ifcontains revset was checking against the set using a pure
__contains__ check. It turns out the set was actually a list of
formatted strings meant for ui output, which meant the contains check failed if
the formatted string wasn't significantly different from the raw value.
This change makes it check against the raw data, prior to it being formatted.
The error only occured when Python didn't have curses - such as on Windows and
when Python was built without curses support.
No curses can also be emulated by (re)moving .../lib/python2.7/curses/ from the
Python installation.
It is left as an exercise to figure out exactly what changed in Mercurial that
triggered this error.
When invoked from another directory, the matchers m._cwd will be the absolute
path. The code for calculating relative path to .hglf did not consider that and
log would fail with weird errors and paths.
For now, just don't do any largefile magic when invoked from other directories.
Revset calls use to return a list. Graft use to mutate that list. We cannot do
this anymore leading to a crash when grafting multiple changeset with a revset.
File ".../mercurial/commands.py", line 3117, in graft
revs.remove(rev)
AttributeError: '_addset' object has no attribute 'remove'
We are late in code-freeze so we make the shortest possible fix by turning it
back to a list.
The documentation says we exit 1 if we have nothing to do, so avoid
breaking that contract when we're passed an empty revset.
This was changed in http://www.selenic.com/hg/rev/1d4f2abc281b to
improve the error message; keep the improved message, just not the
abort.
Command server is designed to use the channel protocol even if the server
process is accessible to tty, whereas vanilla hg should be able to read
password from tty in that case. So it isn't enough to swap sys.stdin:
# works only if the server process is detached from the console
sys.stdin = self.fin
getpass.getpass('')
sys.stdin = oldin
or test isatty:
# vanilla hg can't talk to tty if stdin is redirected
if self._isatty(self.fin):
return getpass.getpass('')
else:
...
Since ui.nontty flag is undocumented and command-server channels don't provide
isatty(), this change won't affect the other uses of ui._isatty().
issue3161 also suggests to provide some context of messages. I think it can
be implemented by using the generic templating function.
We make sure any exceptions raised during the whole span of handling bundle2
processing are decorated. This let us catch exceptions raised by hooks prior to
transaction commit.
Same drill again. We catch the PushRaced error, check if it cames from
a bundle2 processing, if so we turn it into a bundle2 with a part
transporting error information to be reraised client side.
If the heads on the server differ from the ones reported seen by the client at
bundle time, we raise a PushRaced exception. However, the part raising the
exception was broken.
To fix it, we move the PushRaced class in the error module so it can be
accessible everywhere without an import cycle.
A test is also added to prevent regression.
Same as for Abort error, we catch the error, encode it into a bundle2 reply
(expected by the client) and stream this reply. The client processing of the
error will raise the exception again.
Clients expect a bundle2 reply to their bundle2 submission. So we
catch the Abort error and turn it into a bundle2 containing a part
transporting the exception data. The unbundling of this reply will
raise the error again.
Bid merge is a new rarely used feature that the user explicitly enabled - we
should tell/warn when the user actually is using it, just like we tell when we
not are using it.
Give a message like
note: merging 3b08d01b0ab5+ and adfe50279922 using bids from ancestors 0f6b37dbe527 and 40663881a6dd
Most UTF-8 aware terminals convert multibyte sequences into a single displayed
characters. Because the first column is padded by counting bytes, the second
column is not perfectly aligned in the presence of non ASCII characters.
We highlight the fact that this is experimental by moving it to an "experimental"
section, and we match the config name with the server capability name
`bundle2-exp`.
All currently core parts are moved to a `bx2` namespace (for "bundle 2
experimental"). This should avoid conflicts between the final stable
format and the one about to be released.
The current implementation of bundle2 is still very experimental and the 3.0
freeze is yesterday. The current bundle2 format has never been field-tested, so
we rename the header to HG2X. This leaves the HG20 header available for real
usage as a stable format in Mercurial 3.1.
We won't guarantee that future mercurial versions will keep supporting this
`HG2X` format.
When a reply is built, the bundle processing will capture the output of each
handler and sends it to the client in a dedicated part.
As a side effect, this add a "remote: " prefix to destination output on local
push. This is considered okay for now as:
1. bundle2 is still experimental,
2. Matt said he could be okay to change output for bundle2,
3. This keeps the implementation simple.
This changeset does it for stdout only. stderr will be done in a future changeset.
The bundle2 processing does not create a bundle2 reply by default anymore. It
is only done if the client requests it with a `replycaps` part. This part is
called `replycaps` as it will eventually contain data about which bundle2
capabilities are supported by the client.
We have to add a flag to the test command to control whether a reply is
generated or not.
The basic idea is to do the merge planning with all the available ancestors,
consider the resulting actions as "bids", make an "auction" and
automatically pick the most favourable action for each file.
This implements the basic functionality and will only consider "keep" and
"get" actions. The heuristics for picking the best action can be tweaked later
on.
By default it will only pass ctx.ancestor as the single ancestor to
calculateupdates. The code path for merging with a single ancestor is not
changed.
Now that revsets work in a lazy way, log code can be changed to parse every
option into a revset and then evaluate it lazily.
Now expressions like
"hg log -b default -b ."
are converted into a revset using the same code as graphlog.
Multiple revisions can be specified in merge.preferancestor, separated by
whitespace. First match wins.
This makes it possible to overrule the default of picking the common ancestor
with the lowest hash value among the "best" (introduced in f19507e1bcf2).
This can for instance help with some merges where the 'wrong' ancestor is used.
There will thus be some overlap between this and the problems that can be
solved with a future 'consensus merge'.
Mercurial will show a note like
note: using 40663881a6dd as ancestor of 3b08d01b0ab5 and adfe50279922
alternatively, use --config merge.preferancestor=0f6b37dbe527
when the option is available, listing all the alternative ancestors.
Show a message like
note: using 0f6b37dbe527 as ancestor of adfe50279922 and cf89f02107e5
So far this is just a warning - there is nothing the user can do to select
another ancestor.
Before this patch, each log entries in "changelog" and "revisions"
pages of "spartan" style are not aligned by column, because:
- each log entries are separated "<table>" entries, and
- there are no fixed "width" information for each "<th>"/"<td>" entries
This patch aligns entries in "changelog" and "revisions" pages of
"spartan" style by:
- adding 'label' class to '<th>' for 'age' information, and
- setting 'width' of '<th class="label">' with fixed size
'class="age"' is not used for this purpose, because it is also used to
set "bold" font-weight
"16em" seems to be wide enough to show date information fully, when
web browser disables (or doesn't support) javascript.
Before this patch, revision numbers and hash values in "comparison"
page are gotten from not changelog but filelog.
Such filelog information is useful only for hgweb debugging, and may
confuse users.
This patch shows revision numbers and hash values gotten from
changelog in "comparison" page.
Before this patch, "parents" in pages for file doesn't show as same
parents as "hg parents -r REV FILE", when the specified file is not
modified in the specified revision.
For example, it is assumed that revision A, B and D change file "f".
changelog (A) ---> (B) ---> (C) ---> (D)
filelog "f" (x) ---> (y) ------------> (z)
"/file/D/f" invokes "webutil.parents()" with filectx(z) gotten from
changectx(D), and it returns changectx(B). This is as same result as
"hg parents -r D f".
In the other hand, "/file/C/f" invokes "webutil.parents()" with
filectx(y') gotten from changectx(C), and it returns changectx(A),
because filectx(y') is linked to changectx(B), and works like
filectx(y) in some cases.
In this case, revision B is hidden from users browsing file "f" in
revision C.
This patch shows as same parents as "hg parents -r REV FILE" in pages
for file, by making "webutil.parents()" return:
- "linkrev()"-ed revision only, if:
- specified context instance is "filectx" (because
"webutil.parents()" is invoked with changectx, too), and
- (1) the revision from which filectx is gotten and (2) the one to
which filectx is linked are different from each other
- revision gotten from "ctx.parents()", otherwise
Before this patch, "comparison" shows unexpected result, when the
specified file is not modified in the specified revision, even though
"diff" shows empty result.
When REV doesn't change specified FILE, "diff" shows:
"hg diff -c REV FILE"
but "comparison" shows:
"hg diff -c `hg parents -r REV FILE` FILE"
In other words, the former gets parent from changelog, but the latter
gets one from filelog.
This may confuse users browsing (and switching "diff" and
"comparison" of) files in the specified revision.
This patch makes "comparison" get parent from not filelog but
changelog, to show "hg diff -c REV FILE" in both "diff" and
"comparison" pages.
This patch also fixes same problem of "coal" style, because it re-uses
"filerevision.tmpl" of "paper" style.
"gitweb" and "monoblue" styles don't have such problems.
"spartan" style doesn't have "bookmarks" page definition itself.
In case we have revs to strip, delete the bookmark after the strip succeeds, not
beforehand as we might still abort due to dirty working directory, etc.
This function allows returning only the nth "word" from a string. By default
a string is split as by Python's split() function default, but an optional
third parameter can also override what string the string is split by.
Log for largefiles was failing for graph log since it was overriding match
instead of matchandpats.
[Mads Kiilerich modified this patch to address his review comments and ended up
rewriting/removing most of it.]
[Mads Kiilerich placed this patch before the patch that makes graphlog actually
work correctly for largefiles. As it is introduced here it just adds test
coverage and the actual bugfix patch will show the actual change.]
Before this patch, "contrib/check-code.py" can't detect "% inside _()"
correctly, when there are leading whitespaces before the format
string, like below:
_(
"format string %s" % v)
This patch adds regexp pattern "[ \t\n]*" before the pattern matching
against the format string.
"[\s\n]" can't be used in this purpose, because "\s" is automatically
replaced with "[ \t]" by "_preparepats()" and "\s" in "[]" causes
nested "[]" unexpectedly.
This function returns a string only if it starts with a given string.
It is particularly useful when combined with splitlines and/or used with
conditionals that fail when empty strings are passed in to take action
based on the contents of a line.
This is useful for applying changes to each line, and it's especially powerful
when used in conjunction with conditionals to modify lines based on content.
This change allows the origin() and destination() revsets to yield the same
results in the new and old repos after a conversion. Previously, nothing would
be listed for queries in the new repo.
Like the SHA1 updates to the commit messages, this is only operational when the
'convert.hg.saverev=True' option is specified. If the old reference cannot be
found, it is left as-is. It seems slightly better to leave stale evidence of
the graft/transplant/rebase than to eliminate it entirely.
Otherwise diff may get separated from the corresponding prompt by
other threads. This required moving the interactive prompting from one
helper method to another.
