pack_dirstate: only invalidate mtime for files written in the last second Previously we'd place files written in the last second in the lookup set. This can lead to pathological cases where a file always remains in the lookup set if it gets modified before the next time status is run. With this patch, only the mtime of those files is invalidated. This means that if a file's size or mode changes, we can immediately declare it as modified without needing to compare file contents.

dirstate.status: don't ignore symlink placeholders in the normal set On Windows, there are two ways symlinks can manifest themselves: 1. As placeholders: text files containing the symlink's target. This is what usually happens with fresh clones on Windows. 2. With their dereferenced contents. This happens with clones accessed over NFS or Samba. In order to handle case 2, ca6cebd8734e made dirstate.status ignore all symlink placeholders on Windows. It doesn't ignore symlinks in the lookup set, though, since those don't have the link bit set. This is problematic because it violates the invariant that `hg status` with every file in the normal set produces the same output as `hg status` with every file in the lookup set. With this change, symlink placeholders in the normal set are no longer ignored. We instead rely on code in localrepo.status that uses heuristics to look for suspect placeholders. An upcoming patch will test this out by no longer adding files written in the last second of an update to the lookup set.

localrepo.status: ignore empty symlink placeholders A symlink's target should never be empty in normal use. Solaris and some BSDs do allow empty symlinks to be created (with varying semantics on dereference), but a symlink placeholder that started off as empty is either - going to be empty, in which case ignoring it is fine, since it's unchanged, or - going to not be empty, in which case this check is irrelevant.

Added signature for changeset 335a558f81dc

Added tag 2.7.1 for changeset 335a558f81dc

tags: write tag overwriting history also into tag cache file (issue3911) Before this patch, tag overwriting history is not written into tag cache file ".hg/cache/tags". This may give higher priority to local tag than global one, even if the former is overwritten by the latter, because tag overwriting history is used to compare priorities of them (as "rank"). In such cases, "hg tags" invocations using tag cache file shows incorrect tag information. This patch writes tag overwriting history also into tag cache file.

histedit: add description about "histedit --outgoing" to command help Before this patch, there is no explicit description that argument is treated as the URL of the destination repository when "--outgoing" is specified. This patch adds description about "histedit --outgoing" to command help of it.

histedit: add description about basic histedit function to command help Before this patch, there is no explicit description that histedit edits changesets between specified ancestor and the parent of the working directory: users may notice it by error message "REV is not an ancestor of working directory". This patch adds description about basic histedit function to command help of it. This patch uses term "ancestor" instead of "parent", because it seems to be more suitable, and almost all (error) messages already use it.

rebase: handle bookmarks matching revset function names (issue3950) We handled these correctly with all rev-specifying options except, somehow, -r/--rev.

dispatch: add ability to specify a custom pdb module as a debugger This adds the ability to specify a config option, ui.debugger, to a custom pdb module, such as ipdb, and have mercurial use that as its debugger. As long as the value of ui.debugger is a loadable module with the set_trace and post_mortem functions, then dispatch will be able to use the custom module. Debugging _parseconfig is still available in the case of an error since it will be caught with a default the value of pdb.post_mortem.

dispatch: move command line --config argument parsing to _runcatch() Previously, command line parsing of --config arguments was done in _dispatch. This means that it takes place after activating the debugger. In an upcoming patch, we will add a ui.debugger setting so we need to have this parsing done before _runcatch.

mq: update subrepos when applying / unapplying patches that change .hgsubstate Up until now applying or unapplying a patch that modified .hgsubstate would not work as expected because it would not update the subrepos according to the .hgsubstate change. This made it very easy to lose subrepo changes when using mq. This revision also changes the test-mq-subrepo test so that on the qpop / qpush tests. We no longer use the debugsub command to check the state of the subrepos after the qpop and qpush operations. Instead we directly run the id command on the subrepos that we want to check. The reason is that using the debugsub command is misleading because it does not really check the state of the subrepos on the working directory (it just returns what the change that is specified on a given revision). Because of this the tests did not detect the problem that this revision fixes (i.e. that applying a patch did not update the subrepos to the corresponding revisions). # HG changeset patch # User Angel Ezquerra <angel.ezquerra@gmail.com> # Date 1376350710 -7200 # Tue Aug 13 01:38:30 2013 +0200 # Node ID 60897e264858cdcd46f89e27a702086f08adca02 # Parent 2defb5453f223c3027eb2f7788fbddd52bbb3352 mq: update subrepos when applying / unapplying patches that change .hgsubstate Up until now applying or unapplying a patch that modified .hgsubstate would not work as expected because it would not update the subrepos according to the .hgsubstate change.

subrepo: make submerge() return the merged substate This will be useful when reusing submerge() to improve the handling of subrepos on mq. # HG changeset patch # User Angel Ezquerra <angel.ezquerra@gmail.com> # Date 1377117244 -7200 # Wed Aug 21 22:34:04 2013 +0200 # Node ID 2defb5453f223c3027eb2f7788fbddd52bbb3352 # Parent a5c90acff5e61aae714ba6c9457d766c54b4f124 subrepo: make submerge() return the merged substate This will be useful when reusing submerge() to improve the handling of subrepos on mq.

mq: look for modified subrepos when checking for local changes It was possible to apply, unapply, fold, patches (etc) with modified subrepos, which resulted in surprising behavior. For example it was easy to apply a patch with a modified subrepo, and then the refresh it and accidentally end up including the modified subrepo on the refreshed patch. A test has been added to verify this new check. # HG changeset patch # User Angel Ezquerra <angel.ezquerra@gmail.com> # Date 1375742979 -7200 # Tue Aug 06 00:49:39 2013 +0200 # Node ID a5c90acff5e61aae714ba6c9457d766c54b4f124 # Parent 6ac206fb6f27492a98f46bbff090407ee1b1de72 mq: look for modified subrepos when checking for local changes It was possible to apply, unapply, fold, patches (etc) with modified subrepos, which resulted in surprising behavior.

localrepo: get value from the unfiltered caches should check if the attribute existed. If the attribute existed already, it should be returned by getattr(). Otherwise, it will be evaluated again.

hgweb: always run search when a query is entered (bc) This changes the behavior for queries which point at a revision directly, now the output is consistent to other cases: it results in only this matched revision shown, not the log starting with it. A new test checks this behaviour and fails for the old one.

hgweb: search() function supports direct pointing to revision This doesn't change the behavior, as queries directly pointing to revisions are not delegated to the search() function now.

hgweb: pass arguments which a function depends on explicitly in search This changes makes clearer which arguments can a function depend on. Now all the modified functions depend on the 'query' argument only, but future additions will change it.

hgweb: add dynamic search function selection, depending on the query This allows adding other specific search functions, in addition to current keyword search.

unionrevlog: extract 'baserevision' and 'baserevdiff' methods This makes possible to use unionrevlog class with subclasses of revlog that override revlog's 'revision' and 'revdiff' methods. In particular this change is necessary to implement manifest compression, as it allows extension to replace manifest class and override 'revision' amd 'revdiff' methods there.

bundlerevlog: extract 'baserevision' method This makes possible to use bundlerevlog class with subclasses of revlog that override revlog's 'revision' method. In particular this change is necessary to implement manifest compression, as it allows extension to replace manifest class and override 'revision' method there.

solaris: tests can't use tail -n Solaris tail doesn't recognize the -n option. Replace the one use of it with some inline python code, and add a test case to check-code.py.

solaris: sed doesn't recognize a line without a newline

solaris: test cases can't use grep -a The -a option to GNU grep isn't available when using Solaris grep. Replace the one use of grep -a in the testsuite with some in-line Python that does the equivalent, and add a check for grep -a in check-code.py.

revlog: pass node as an argument of addrevision This change will allow revlog subclasses that override 'checkhash' method to use custom strategy of computing nodeids without overriding 'addrevision' method. In particular this change is necessary to implement manifest compression.

revlog: extract 'checkhash' method Extract method that decides whether nodeid is correct for paricular revision text and parent nodes. Having this method extracted will allow revlog subclasses to implement custom way of computing nodes. In particular this change is necessary to implement manifest compression.

histedit: discard meaningless comment about 'hexlify node' Refactoring in 26b41a902195 made this comment meaningless. The node gotten by "discovery.findcommonoutgoing()" is hexlified in "between()" by "repo.set('%n::%n', old, new)".
