This improves the misleading error message
$ hg identify
abort: there is no Mercurial repository here (.hg not found)!
to the more explicit
$ hg identify
abort: requirement 'fake' not supported!
for all commands in commands.optionalrepo, which includes the identify
and serve commands in particular.
This is for the case when a new entry in .hg/requires will be defined
in a future Mercurial release.
Previously, when rolling back a transaction, some users could be confused
between the level to which the store is rolled back, and the new parents
of the working directory.
$ hg rollback
rolling back to revision 4 (undo commit)
With this change:
$ hg rollback
repository tip rolled back to tip revision 4 (undo commit)
working directory now based on revision 2 and 1
So now the user can realize that the store has been rolled back to an older
tip, but also that the working directory may not on the tip (here we are
rolling back the merge of the heads 2 and 1)
The default behaviour is to commit subrepositories with uncommitted changes. In
my experience this is usually undesirable:
- Changes to dependencies are often debugging leftovers
- Real changes should generally be applied on the source project directly,
tested then committed. This is not always possible, subversion subrepos may
include only a small part of the source project, without the tests.
Setting ui.commitsubrepos=no will now abort commits containing such modified
subrepositories like:
$ hg --config ui.commitsubrepos=no ci -m msg
abort: uncommitted changes in subrepo sub
I ruled out the hook solution because it does not easily take --include/exclude
options in account. Also, my main concern is whether this flag could cause
problems with extensions. If there are legitimate reasons for callers to
override this behaviour (I could not find any), they might either override at ui
level, or we could add an argument to localrepo.commit() later.
v2:
- Renamed ui.commitsubs to ui.commitsubrepos
- Mention the configuration entry in hg help subrepos
Add missing calls to close() to many places where files are
opened. Relying on reference counting to catch them soon-ish is not
portable and fails in environments with a proper GC, such as PyPy.
Defers updating the fncache file with newly added entries to the end of
the transaction (on e.g. pull), doing a single open call on the fncache
file, instead of opening and closing it each time a new entry is added
to the store.
Implemented by adding a new abstract write() function on store.basicstore
and registering it as a release function on the store lock in
localrepo.lock (compare with dirstate.write).
store.fncachestore overrides write() from basicstore and calls a new
write function on the fncache object, which writes all entries to the
fncache file if it's dirty.
store.fncache.add() now just marks itself as dirty if a new name is added.
Some extensions (e.g. hgsubversion) completely override push command. Because
extensions load order is unspecified, if hgsubversion loads before mq, mq
checks about not pushing applied patches will be bypassed. Short of finding a
way to fix load order, extracting the checking logic will allow
hgsubversion-like extensions to run the check themselves.
The generation of cache files like tags.cache and branchheads.cache is not an
actual reflection of things changing in the whole of the .hg directory (like eg
a commit or a rebase or something) but instead these cache files are just part
of bookkeeping. As such its convienant to allow various clients to ignore file
events to do with these cache files which would otherwise cause a double
refresh. Eg one refresh might occur after a commit, but the act of refreshing
after the commit would cause Mercurial to generate a new branchheads.cache which
would then cause a second refresh, for clients.
However if these cache files are moved into a directory like eg .hg/cache/ then
GUI clients on OSX (and possibly other platforms) can happily ignore file events
in this cache directory.
split can be more readable for longer lists like the list in
dirstate.invalidate. As dirstate.invalidate is used in wlock() and therefoe
used heavily, I think it's worth avoiding a split there too.
This patch avoids empty commit when .hgsubstate is dirty. Empty commit
was caused by .hgsubstate being updated back to the state of the
working copy parent when committing, if a user had changed it manually
and not made any changes in subrepositories.
The subrepository state from the working copies parent is compared
with the state calculated as a result of trying to commit the
subrepositories. If the two states are the same, then return None
otherwise the commit is just done.
The line: "committing subrepository x" will be written if there is
nothing committed, but .hgsubstate is dirty for x subrepository.
This uses the same strategy as progress for pulls, estimating manifests
based on changeset count and estimating file count by files list in
each changeset.
The opener already unlinks the filename before 'w'riting, for both
the symlink and the normal file case. It also now resets the flags
for normal files on 'w'rite, which makes this os.unlink call completely
redundant.
For Windows, removing this extra unlink call helps to avoid tripping
issue2524 (os.unlink followed by a write).
Previously, branch names were ideally manipulated as UTF-8 strings,
because they were stored as UTF-8 in the dirstate and the changelog
and could not be safely converted to the local encoding and back.
However, only about 80% of branch name code was actually using the
right encoding conventions. This patch uses the localstr addition to
allow working on branch names as local strings, which simplifies
handling so that the previously incorrect code becomes correct.
When issuing `hg pull -r REV` in a repo with no common ancestor with the
remote repo, the message 'requesting all changes' is printed, even though only
the changese that are ancestors of REV are actually requested. This can be
confusing for users (see
http://www.selenic.com/pipermail/mercurial/2010-October/035508.html).
This silences the message if (and only if) the '-r' option was passed.
- Mac OS X has problems with filenames starting with '._'
(e.g. '.FOO' -> '._f_o_o' is now encoded as '~2e_f_o_o')
- Explorer of Windows Vista and Windows 7 strip leading spaces of
path elements of filenames when copying trees
Above problems are avoided by encoding the first space (as '~20') or
period (as '~2e') of all path elements.
This introduces a new entry 'dotencode' in .hg/requires, that is,
a new repository filename layout (inside .hg/store).
Newly created repositories require 'dotencode' by default. Specifying
[format]
dotencode = False
in a config file will use the old format instead.
Prior Mercurial versions will abort with the message
abort: requirement 'dotencode' not supported!
when trying to access a local repository that requires 'dotencode'.
New 'dotencode' repositories can be converted to the previous
repository format with
hg --config format.dotencode=0 clone --pull repoA repoB
This patch fixes issues with stream cloning in the presense of parentdelta,
lwcopy and similar additions that change the interpretation of the revlog
format, or the format itself.
Currently, the stream capability is sent like this:
stream=<version of changelog>
But the client doesn't actually check the version number; also, it only checks
the changelog and it doesn't capture the interpretation-changes and
flag-changes in parentdelta and lwcopy.
This patch removes the 'stream' capability whenever we use a non-basic revlog
format, to prevent old clients from receiving incorrect data. In those cases,
a new capability called 'streamreqs' is added instead. Instead of a revlog
version, it comes with a list of revlog-format relevant requirements, which
are a subset of the repository requirements, excluding things that are not
relevant for stream.
New clients use this to determine whether or not they can stream. Old clients
only look for the 'stream' capability, as always. New servers will still send
this when serving old repositories.
