Monotone used '1' for close while core Mercurial use 1. Now, for consistency,
use the same value everywhere. It will be stored as a string anyway and the
change will not make any real difference.
(The actual value of 'close' doesn't matter as long as extras has such a key.)
All current callers supply some sort of prefix, so the issue was hidden. But if
no parameter was specified, a crash occurred in the write() closure when
concatenating 'prefix' and 'name'.
When there isn't lfdirstate file in cases below, "openlfdirstate()"
call "scmutil.match()" indirectly to build lfdirstate up.
- subrepos disabling largefiles locally
- lfdirstate file is missed accidentally
This causes infinite recursive call of "openlfdirstate()" in
"overriderevert()" (introduced by 25febe9568dd), because
"openlfdirstate()" is invoked from the function overriding
"scmutil.match()" itself.
To avoid infinite recursive call of "openlfdirstate()" in
"overriderevert()" in such cases, this patch passes "create=False"
argument to "openlfdirstate()".
"create=False" forcibly makes "openlfdirstate()" avoid code path to
build lfdirstate up.
Even if largefiles extension is enabled in a repository, "repo"

(4) update/revert with a subrepo disabling largefiles
In these cases, overridden functions cause accessing to largefiles
specific fields of not "largefiles.reposetup()"-ed "repo" object, and
execution is aborted.
- (1), (2), (4) cause accessing to "_lfstatuswriters" in
"getstatuswriter()" invoked via "updatelfiles()"
- (3) causes accessing to "_lfcommithooks" in "overriderebase()"
For safe accessing to these fields, this patch examines whether passed
"repo" object is "largefiles.reposetup()"-ed or not before accessing
to them.
This patch chooses examining existence of newly introduced
"_largefilesenabled" instead of "_lfcommithooks" and
"_lfstatuswriters" directly, because the former is better name for the
generic "largefiles is enabled in this repo" mark than the latter.
In the future, all other overridden functions should avoid largefiles
specific processing for efficiency, and "_largefilesenabled" is better
also for such purpose.
BTW, "lfstatus" can't be used for such purpose, because some code
paths set it forcibly regardless of existence of it in specified
"repo" object.
The previous code was adding standin files to the matcher's file list when
neither the standin file nor the original existed in the context. Somehow, this
was confusing the logging code into behaving differently from when the extension
wasn't loaded.
It seems that this was an attempt to support naming a directory that only
contains largefiles, as a test fails if the else clause is dropped entirely.
Therefore, only append the "standin" if it is a directory. This was found by
running the test suite with --config extensions.largefiles=.
The first added test used to log an additional cset that wasn't logged normally.
The only relation it had to file 'a' is that 'a' was the source of a move, but
it isn't clear why having '.hglf/a' in the list causes this change:

Note that there is still something fishy with the largefiles code, because when
using a glob pattern like this:
$ hg log 'glob:sub/*'
the pattern list would contain '.hglf/glob:sub/*'. None of the tests show this
(this test lives in test-largefiles.t at 1349), it was just something that I
noticed when the code was loaded up with print statements.
Convert will try to find references to revisions in commit messages and replace
them with references to the converted revision. It will take any string that
looks like a hash (and thus also decimal numbers) and look it up in the source
repo. If it finds anything, it will use that in the commit message instead.
It would do that for all hex digit sequences of 6 to 40 characters. That was
usually no problem for small repos where it was unlikely that there would be a
matching 6 'digit' hash prefix. It was also no problem on repos with less than
100000 changesets where numbers with 6 or more digits not would match any
revision number. With more than 100000 revisions random numbers in commit
messages would be replaced with a "random" hash. For example, 'handle 100000
requests' would be changed to to 'handle 9117c6 requests'. Convert could thus
not really be used on real repositories with more than 100000 changesets.
The default hash length shown by Mercurial is 12 'digits'. It is unexpected and
unwanted that convert by default tries to replace revision references that use
less than that amount of 'digits'.
To fix this, don't match strings that are less than the default hash size of 12
characters.
Before this changeset rebase was getting very confused if any revision in the
rebase set became hidden. This was fairly easy to achieve if a rebased revision
was made visible by the working copy location. The rebase process would update
somewhere else and the revision would become hidden.
To work around this issue, we ensure rebased revisions remain visible for the
whole process.
This is a simple change suitable for stable. More subtle usage of unfiltered
repository in rebase may solve this issue more cleanly.
b8552020f458 broke things ... and the following cleanups didn't fix all issues.
It didn't work with the diffargs shipped in mergetools.rc with explicit
quoting. Parameters would end up with being quoted twice - especially if they
really needed quoting.
To work around that, look for explicit quotes around the variables that will be
substituted with proper quoting. Also accept an additional prefix so we can
handle both
--foo='$parent'
and
'--foo=$parent'
It will however still fail if the user intentionally place the variable inside
a quoted string, as in
'parent $parent is on the left'
There is currently no good way to handle that, short of knowing exactly which
quoting mechanism will be used.
This effectively reverts 9fc565fa1621, which caused some normal file copies to
not be displayed as copies. Other normal file copies could be displayed- the
exact reason isn't clear. This also adds two tests that were failing prior to
this backout, so that this can be sorted out next cycle.
The difference between copy cases that worked and those that didn't seemed to be
in copies.pathcopies(). When largefiles isn't enabled for the changed test, or
lfstatus is not set in the commands.status() override, 'y.ancestor(x) == x'.
That wasn't true otherwise, which fell through to the _chain() method. In this
case, the copy is removed in the criss cross loop.
'y.ancestor(x)' returns a context.changectx type, while 'x' is a lfilesctx type
in the failing case. I tried adding the ancestor method to the lfilesctx class
to change the type of the ancestor context, however the context when printed as
a string then gains a '+'. This points to it being a context.committablectx,
which clearly isn't correct for an ancestor. Possibly the problem is the
lfilesctx needs to subclass context.committablectx in some cases, but
context.changectx in others, within the same invocation? I'm not sure how to
pull that off, and backing out this change is safer during the freeze.
As to the status changing when a path is specified, I haven't looked into it
yet.
We use -T consistently elsewhere to refer to the --template option.
The old -t option is now renamed to --oldtemplate so that -t still
works. This has the benign side effect of introducing and immediately
deprecating a new long option.
We also test with both -t and -T options.
Previously, when a largefile is forgotten and then reverted, a warning was
issued:
$ hg revert -R subrepo subrepo/large.txt
file not managed: subrepo/large.txt (glob)
This was purely cosmetic as the file itself actually was reverted.
The problem was even with all of the matcher patching, the largefile pattern
given on the command line wasn't converted to a standin because the standin was
neither in ctx nor wctx. This causes the named largefile to be added to the
'names' dict in cmdutil.revert() in the repo walk at line 2550. The warning was
printed out when the 'names' dict is iterated, because the file was specified
exactly.
Since core revert recurses into subrepos and largefiles only overrides the
revert method in commands.py, it doesn't work properly when reverting a subrepo.
However, it still will recurse into the subrepo and call the installed matcher
method, so lfdirstate is reopened for the current repo level to prevent any new
problems.
Previously, the histedit state object was being recreated during continue/abort.
This meant that the locks that were held on the original state object were not
available to actions, which meant actions could not release the lock on the
repository (like an 'exec' action would need to do).
This affected our internal extension that added the 'exec' action.
This is in line with the documentation on the base class method, and is related
to issue4496 (but doesn't fix the reporter's problem of not mangling other data
that matches a revision pattern). Now instead of aborting when there is an
ambiguous source rev, it simply won't update the commit comment. A warning
message might be nice, but a None return masks whether the problem was no
matching revision, or more than one.
The only other caller of this is the logic that converts tags, but those are
never ambiguous since they are always 40 characters.
A test isn't feasible because there simply aren't enough commits in the test
suite repos to have an ambiguous identifier that is at least 6 characters long,
and it would be too easy for the ambiguity to disappear when unrelated changes
are made. Instead, I simply ran 'hg --traceback log -r c' on the hg repo, and
handled the error it threw.
When a directory is named in the commit file list, the previous behavior was to
walk the list, and if no normal files in the directory were also named, add the
corresponding standin for each largefile in that directory. The directory is
then dropped from the list, so that committing a directory with no normal file
changes works. It then added the corresponding standin directory for the first
largefile seen, by prefixing it with '.hglf/'.
The latter is unnecessary since each affected largefile is explicitly referenced
by its standin in the list. It also caused an abort if there were no changed
largefiles in the directory, because none of its standins changed:
abort: .hglf/foo/bar: no match under directory!
This list of files is used to tweak a matcher in lfutil.updatestandinsbymatch(),
which is what is passed to commit().
The status() call that is ultimately done in the commit code with this matcher
seems to have some OS specific differences. It is not necessary to append '.'
for Windows to run the largefiles tests cleanly. But if '.' is not added to the
list, the match function isn't called on Linux, so status() would miss any
normal files that were also in a named directory. The commit then proceeds
without those normal files, or says "nothing changed" if there were no changed
largefiles in the directory. This is not filesystem specific, as VFAT on Linux
had the same behavior as when run on ext4. It is also not an issue with
lfilesrepo.status(), since that only calls the overridden implementation when
paths are passed to commit. I dont have access to an OS X machine ATM to test
there.
Maybe there's a better way to do this. But since the standin directory for the
first largefile was previously being added, and that caused the same walk in
status(), there's no preformance change to this. There is no danger of
erroneously committing files in '.', because the original match function is
called, and if it fails, the lfutil.updatestandinsbymatch() tweaked matcher only
indicates a match if the file is in the list of standins- and '.' never is. The
added tests confirm this.
The next diff will add support for writing bundle2 files to writebundle, but
the bundle2 generator wants access to a ui object. This changes the signature
and callsites to pass one in.
Standins are read before and after an update/merge, and all the standins that
changes are handed to updatelfiles for getting their corresponding largefiles
updated. updatelfiles would then hash the largefile and see if it already
matched the new expected hash. If so, it would skip the update. If different,
the largefile would be updated.
It would happen very rarely that the largefile happened to match the new hash
(and thus not the old one) and the hashing would thus be pointless ... and
hashing is not cheap.
Instead, when it is known that the standin hash changed (from an update), just
update the standin unconditionally. If the largefile was "unsure" before the
update, it was hashed at that point, so we know there is nothing to preserve.
(Also, the hashing in updatelfiles was not used to preserve changes, but only
to be lazy about updating the largefile, so nothing is lost by not doing this
extra hashing.)
There might be rare situations where we now will update largefiles that didn't
have to be updated, but in all relevant cases (?) this will improve
performance.
Updates on a repo with some big largefiles has been seen to go from 9.19 s to
6.8 s - that is 26% less painful.
The --large, --normal and --lfsize args couldn't be passed to a subrepo before,
and files in the subrepos would be added silently (if -v wasn't specified) as
normal files. As an added bonus, 'hg add --dry-run' no longer prints that
largefiles would also be added as normal files as well.
0e5f75a52c9d introduced a way to share bookmarks. When a repository share that
shares bookmarks was created, a .hg/bookmarks.shared file was created to mark
the repository share as one that shares its bookmarks.
We have plans to introduce other levels of sharing, including a "full share"
mode. Rather than creating a new ".shared" file for each new thing that we may
want to share It seems better to create a single "shared" file that will list
what is shared for a given shared repository. This should make it much easier
to get a list of everything that is shared by a given shared repository.
The shared file contains a list of shared "items" (such as bookmarks). Each
shared "item" is added as a new line in the file. For now the only possible
entry in the file is "bookmarks".

'hg update' would hash all 'unsure' largefiles before performing the merge. It
would update the standins but not detect the very common case where the
largefile never had been changed by the user but just had been marked with an
invalid dirstate mtime to make sure any changes done by the user in the same
second would be detected. The largefile would remain in that state and would
have to be hashed again next time even though it still not had been changed.
Sad trombone.
Instead, for largefiles listed as 'unsure' or 'modified', after updating the
standin with the actual hash, mark the largefile as normal if it turns out to
not be modified relative to the revision in the parent revision. That will
prevent it from being hashed again next time.
If resolving a merge conflict result in an empty changesets, we now properly
skip the changeset instead of crashing.
Original patch from Robert Collins <robertc@robertcollins.net>.
This will be used to exclude largefile candidates from the normal file matcher,
which will allow add and addremove dryruns to not print a file as both a normal
and a large file.
Core addremove prints the file relative to cwd only if patterns are provided to
the command. Core add always prints relative to cwd. Also, both methods print
the subrepo prefix when needed. The 'already a largefile' doesn't have an
analog in core, but follows the same rules for consistency.
Both cmdutil.remove() and scmutil.addremove() require verbose mode or an inexact
match to print the filename. Core addremove also prints the file relative to
cwd only if patterns are provided to the command. And finally, both methods
print the subrepo prefix when needed.
Currently, if the node no longer exists, the state object fails to load
and pukes with an exception. Changing the state object to only store the
node allows callers to handle these cases. For instance, in
bootstrapcontinue we can now detect that the node doesn't exist and exit
gracefully.
The alternative is to have the state object store something like None
when the node doesn't exist, but then outside callers won't be able to
access the old node for recovery (unless we store both the node and the
ctx, but why bother).
More importantly it allows us to detect this case when doing hg histedit
--abort. Currently this situation results in both --continue and
--abort being broken and the user has to rm .hg/histedit-state to unwedge
their repo.
(description by Durham Goode)
During histedit we don't want user to do any operation resulting in
stripping nodes needed to continue history editing. This patch
wraps the strip function to detect such situations.
MSYS on Windows has a terminal that supports the "win32" color mode
(which "auto" properly detects for us). However, a popularily configured
pager in that environment (GNU less) only supports the "ansi" color
mode.
This patch teaches color about a new config option: pagermode. It
behaves like "mode" but is only consulted when the pager is active for
the current command. MSYS users can now set "pagermode = ansi" and get a
colorful experience that just works. Previously, MSYS users would have
to live without color when using GNU less as the pager, would have to
manually configure the pager to attend every command, or would have
gibberish if "ansi" was used without the pager.
An upcoming patch will teach color to potentially act differently if the
pager is active. Since both extensions wrap the same function
(dispatch._runcommand) to change behavior, we must guarantee that
pager's wrapped function runs before color's so color may read the
breadcrumb left by pager.
A subsequent patch will teach the color extension to do different things
depending on whether a pager is active. This patch leaves a breadcrumb
on the ui instance to allow it do that that.
When cloning a repo that requires largefiles, the user had to either enable the
extension on the command line and then manually edit the local hgrc file after
the clone, or just enable it globally for the user. Since it is a feature of
last resort, and materially affects even repos without any largefiles when it is
enabled, we should make it easier to not have it enabled globally.
This simply adds the enabling statement to the local hgrc if the requires file
mandates its use (which only happens after the first largefile is committed).
That means that a user who works with a mix of largefile and normal repos can
always clone with '--config extensions.largefiles=', and the extension is
permanently enabled or not as appropriate.
The change in test-largefiles.t is simply because the order of loading rebase
and largefiles changed. The same change occurs if the order is flipped in the
hgrc file at the top of the test.
The current color mode detection on Windows assumes the presence of the
TERM environment variable assumes ANSI is supported. However, this isn't
always true. In MSYS (commonly found as part of MinGW), TERM is set to
"cygwin" and the auto resolved color mode of "ansi" results in escape
sequences getting printed literally to the terminal. The output is
very difficult to read and results in a bad user experience. A
workaround is to activate the pager and have it attend all commands (GNU
less in MSYS can render ANSI terminal sequences properly).
In Cygwin, TERM is set to "xterm." Furthermore, Cygwin supports
displaying these terminal sequences properly (unlike MSYS).
This patch changes the mode auto-detection logic on Windows to be more
conservative about selecting the "ansi" mode. We now only select the
"ansi" mode if TERM is set and it contains the string "xterm" or if
we were unable to talk to win32 APIs to determine the settings. There is
a chance this may take away "ansi" from a terminal that actually
supports it. The recourse for this would be to patch the detection to
act appropriately and to override color.mode until that patch has
landed. However, the author believes this regression is tolerable, since
it means MSYS users won't have gibberish printed by default.
Since MSYS's common pager (less) supports display of ANSI sequences,
there is room to patch the color extensions so it can select the ANSI
color mode if a pager is activated.
Mozilla (being an active user of MSYS) would really appreciate this
being part of the stable branch. However, since I believe it is BC, I
haven't explicitly requested application to stable since I figure that
request will be denied.
Adds a configuration setting for allowing users to specify the default behavior
of 'hg histedit' without arguments. This saves users from having to manually
figure out the bottom commit or a complicated revset. My current revset of
choice is "only(.) & draft() - ::merge()"
The commits that histedit can work with is usually quite limited, so if this
feature ends up working well, we may want to consider making "only(.) & draft()
- ::merge()" the default behavior for everyone.
The destination is validated by pathutil.canonpath() for illegal components, and
that it is in the repository. The logic for creating the standin directory tree
was calling this before cmdutil.copy(), but without the destination file name
component. The cmdutil.copy() logic also calls pathutil.canonpath(), but with
the file name component. By always calling the core logic first, the error
message is always consistent. Specifically, the old behavior for these tests
was to say '.hg' contains an illegal component, and '..' is not under root.
A user wasn't likely to notice the discrepancy, but this eliminates a needless
difference when running the test suite with --config extensions.largefiles=.
Previously histedit only stored the short version of the rule nodes in the
state. This meant that later we couldn't resolve a rule node to its full
form if the commit had been deleted from the repo.
Let's store the full form from the beginning.
This is consistent with addlargefiles(), and will make it easier to get the
paths that are printed correct when recursing into subrepos or invoking from
outside the repository. It also now restricts the path that the addremove is
performed on if a path is given, as is done with normal files.
The repo.status() call needs to exclude clean files when performing an
addremove, because the addremove override method calling this used to pass the
list of files to delete, which caused the matcher to only consider those files
in building the status list. Now the matcher is restricted only to the extent
that the caller requested- usually directories if at all. There's no reason for
addremove to care about clean files anyway- we don't want them deleted.
The code for picking a merge ancestor when rebasing merges had a long and
incorrect comment.
The comment would perhaps have been fine as commit message but does
not make the code more readable or maintainable and is a bad
substitute for correct and readable code.
The correct essense of the comment is quite trivial: a merge of an ancestor of
the rebase destination and an 'outside' revision can be rebased as if it was a
linear change, using 'destination ancestor parent' as base and pretty much
ignoring the 'outside' revision.
The code path where the comment is placed is however also used for other kinds
of merge rebases. The comment is thus not really correct and not helpful. I
think it would be better to drop the comment and rewrite the code.
The more aggressive synchronization of lfdirstate that was backed out in
4fe80f20ab06 masked the problem where lfdirstate would hold an 'R' for a
largefile that was added and then removed without a commit between. We could
just conditionally call lfdirstate.drop() or lfdirstate.remove() here, but this
also properly updates lfdirstate if the standin doesn't exist for the file
somehow (i.e. call drop instead of remove).
Without this change, the precommit status in the commit command immediately
after the test change lists the removed (and never committed) largefile as 'R'.
It can also lead to situations where the status command reports the same, long
after the commit [1].
[1] http://www.selenic.com/pipermail/mercurial-devel/2015-January/065153.html
d20af8be6a14 introduced a significant performance regression: All largefiles
were marked 'normallookup' by linear (or noop) updates and had to be rehashed
by the next command.
The previous change introduced a different solution to the problem d20af8be6a14
solved and we can thus back it out again.
This is an alternative solution to the problem addressed by d20af8be6a14. This
implementation has the advantage that it doesn't mark clean largefiles as
normallookup. We can thus avoid repeated rehashing of all largefiles when
d20af8be6a14 is backed out.
This implementation use the existing 'lfmr' actions that 4f7f7352d9d0
introduced for handling another part of the same cases.
If an uncommitted and deleted file was forgotten, a warning would be emitted,
even though the operation was successful. See the previous patch for
'remove -A' for the exact circumstances, and details about the cause.
The bug report doesn't mention largefiles, but the given recipe doesn't fail
unless the largefiles extension is loaded. The problem only affected normal
files, whether or not any largefiles are committed, and only files that have
not been committed yet. (Files with an 'a' state are dropped from dirstate,
not marked removed.) Further, if the named normal file never existed, the
warning would be printed out twice.
The problem is that the core implementation of remove() calls repo.status(),
which eventually triggers a dirstate.walk(). When the file isn't seen in the
filesystem during the walk, the exception handling finds the file in
dirstate, so it doesn't complain. However, the largefiles implementation
called status() again with all of the original files (including the normal
ones, just dropped). This time, the exception handler doesn't find the file
in dirstate and does complain. This simply excludes the normal files from
the second repo.status() call, which the largefiles extension has no interest
is processing anyway.
This is a copy/paste (with the necessary tweaks) of the composenormalfilematcher
method currently on default, which does the inverse- this trims the normal files
out of the matcher. It will be used in the next patch.
This is in the way of passing a matcher to removelargefiles(). This method is
called in exactly two places- first in overrides.addremove() (but only if the
pattern list passed to it is not empty), and second in the commands.remove()
override. But since the latter calls commands.remove() first, which also does
this check, it isn't needed here.
To reduce amount of changes for review-ability, previous patch uses
"args" as argument name of "dodiff()", even though "args" includes
also the name of command to be executed (or full-path of it).
This patch replaces "args" by more appropriate name "cmdline".
Before this patch, all command line arguments for external tools are
quoted by the combination of "shlex.split" and "util.shellquote". But
this causes some problems.
- some problematic commands can't work correctly with quoted arguments
For example, 'WinMerge /r ....' is OK, but 'WinMerge "/r" ....' is
NG. See also below for detail about this problem.
https://bitbucket.org/tortoisehg/thg/issue/3978/
- quoting itself may change semantics of arguments
For example, when the environment variable CONCAT="foo bar baz':
- mydiff $CONCAT => mydiff foo bar baz (taking 3 arguments)
- mydiff "$CONCAT" => mydiff "foo bar baz" (taking only 1 argument)
For another example, single quoting (= "util.shellquote") on POSIX
environment prevents shells from expanding environment variables,
tilde, and so on:
- mydiff "$HOME" => mydiff /home/foobar
- mydiff '$HOME' => mydiff $HOME
- "shlex.split" can't handle some special characters correctly
It just splits specified command line by whitespaces.
For example, "echo foo;echo bar" is split into ["echo",
"foo;echo", "bar"].
On the other hand, if quoting itself is omitted, users can't specify
options including space characters with "--option" at runtime.
The root cause of this issue is that "shlex.split + util.shellquote"
combination loses whether users really want to quote each command line
elements or not, even though these can be quoted arbitrarily in
configurations.
To resolve this problem, this patch does:
- prevent configurations from being processed by "shlex.split" and
"util.shellquote"
only (possibly) "findexe"-ed or "findexternaltool"-ed command path
is "util.shellquote", because it may contain whitespaces.
- quote options specified by "--option" via command line at runtime
This patch also makes "dodiff()" take only one "args" argument instead
of "diffcmd" and "diffopts. It also omits applying "util.shellquote"
on "args", because "args" should be already stringified in "extdiff()"
and "mydiff()".
The last hunk for "test-extdiff.t" replaces two whitespaces by single
whitespace, because change of "' '.join()" logic causes omitting
redundant whitespaces.
Up until now we compared the "path" and "sharedpath" repository properties to
check if a repository is shared. This was relying an implementation detail of
shared repositories. In order to make it possible to change the way shared
repositories are implemented, we encapsulate this check into its own localrepo
method, called shared.
This new method returns None if the repository is shared, and something else
(for now a string describing the short of share) otherwise.
The reason why I did not call this method "isshared" and made it return a
boolean is that I plan to introduce a new type of shared repository soon.
# NOTES:
This is the first patch in a series whose purpose is to add support for
creating "full repository shares", which are repositories that share everything
with the repository source except their current revision, branch and bookmark.
This series is RFC because I am not very sure of some of the solutions I took.
Comments are welcome!
The comment about status being buggy with a repo proxy seems to be that status
wasn't being redirected to testing the largefiles themselves- lfstatus was
always False, and so the original status method was being called instead of
doing the largefiles processing. This is because when the various largefile
command overrides call 'repo.lfstatus = True', __setattr__() in repoview is in
turn setting the value on the unfiltered repo, and the value in the filtered
repo remains False.
Explicitly looking at the attribute on the unfiltered repo keeps all views in
sync.
There is no --after for addremove, so the printing for addremove can be hoisted
out of the 'not after' check. The difference between the two remove messages
reflects the existing difference between core remove and core addremove styles
for printing the file.
There are still some pre-existing issues here. Core addremove only prints on
inexact matches or when verbose. But since the largefiles that are being
removed are passed to removelargefiles() as a pattern list, there is never an
inexact match, which would keep the largefiles from being printed at all unless
verbose is specified. Therefore, the output is a little more aggressive than
core. The addremove print style here is also inconsistent with core- it should
use matcher.uipath(f) instead of f. These can be fixed once a matcher is passed
in.
The function only adds the hash content of the file to the set to upload if the
file in the ctx is a standin. It is called by overrides.summaryremotehook(),
which is called in the summary method. The largefiles extension switches
'lfstatus' on in summary, so the standins shouldn't be visible when obtaining a
context there.
The reason this wasn't noticed before is that the 'lfstatus' attribute is only
being set on the unfiltered repo because of how repoview delegates attribute
assignment. Therefore any filtered view will return a context containing
standins, whether or not 'lfstatus' was set in the various overrides methods.
That will be fixed in the next patch. But without this change, the next patch
would have test failures for 'summary --large' stating there are no files to
upload.
When a directory was renamed and a new untracked file was added in the
new directory and the remote directory added a file by the same name
in the old directory, the local untracked file gets overwritten, as
demonstrated by the broken test case in test-rename-dir-merge.
Fix by checking for unknown files for 'dg' actions too. Since
_checkunknownfile() currently expects the same filename in both
contexts, we need to add a new parameter for the remote filename to
it.
This simplifies largefiles' overridecalculateupdates(), which no
longer has to do the conversion it started doing in 478d610ca1b0
(largefiles: rewrite merge code using dictionary with entry per file,
2014-12-09).
To keep this patch small, we'll leave the name 'actionbyfile' in
overrides.py. It will be renamed in the next patch.
The hack for method monkey patching on repoview has been ruled out as
fragile, so we are rolling it back. We'll expand the explanation in the next
changeset.
The stored path contains platform specific separators, so splitting on '/.hg'
returned the string unmodified on Windows. The source was then looked for in
$source/.hg/.hg, which obviously fails. This caused cascading errors in
test-share.t relating to the recent bookmark support.
Merged files are considered modified at commit time even if only 1 parent
differs. In this case we must use the change context of this parent for
expansion.
The issue went unnoticed for long because it is only apparent until the next
update to the merge revision - except in test-keyword where it was always
staring us in the face.
This patch adds the -B/--bookmarks option to the share command added by the
share extension. All it does for now is create a marker, 'bookmarks.shared',
that will be used by future code to implement the sharing functionality.
Unicode and Python's unicode.splitlines() treat several extra legacy
ASCII codepoints as linebreaks, even though the vast bulk of computing
and Python's own str.splitlines() do not. Rather than introduce line
numbering confusion, we filter them out when highlighting.
The state mapping also contains some magic negative values (detached
parent, ignored revision). Blindly reading the state thus lead to
unfortunate usage of the negative value as an update destination. We
now filter them out.
We do a minor alteration of the test to catch this.
Mq tried to insert headers in the right order. Sometimes it would stop
searching before checking all headers and it could thus duplicate a header
instead of replacing it.
Changeset 5b64e22ecd8e introduced the examination of exec bit of
largefiles in "hg status --rev REV" case, but it doesn't avoid it on
the platform being unaware of exec-bit (e.g. on NTFS of Windows).
Fix inconsistent handling of plain header separation in mq patcheader - and
contrary to 05acc6157816, do it in the direction of having an empty line
between header and description. Plain patches are like mails and should thus
have an empty line between headers and body in compliance with RFC 822 3.1.
The new rebase revset didn't check for the case when there are no common
ancestors. Now it does. The new behavior should be the same as the pre-3.2
behavior. Added a test.
