convert: when converting from Perforce use original local encoding by default On Windows Perforce command line client uses default system locale to encode output. Using 'latin_1' causes locale-specific characters to be replaced with question marks. With this patch we will use default locale by default whilst allowing to specify it explicity with 'convert.p4.encoding' config option. This is a potentially breaking change for any scripts relying on output treated as in 'latin_1' encoding. Also because hgext.convert.convcmd overwrites detected default system locale with UTF-8 we had to introduce an import cycle in hgext.convert.p4 to retrieve originally detected encoding from hgext.convert.convcmd.

convert: when getting file from Perforce concatenate data at the end As it turned out, even when getting relatively small files, concatenating string data every time when new chunk is received is very inefficient. Maintaining a string list of data chunks and concatenating everything in one go at the end seems much more efficient - in my testing it made getting 40 MB file 7 times faster, whilst converting of a particularly big changelist with some big files went down from 20 hours to 3 hours.

help: scripting help topic There are a lot of non-human consumers of Mercurial. And the challenges and considerations for machines consuming Mercurial is significantly different from what humans face. I think there are enough special considerations around how machines consume Mercurial that a dedicated help topic is warranted. I concede the audience for this topic is probably small compared to the general audience. However, lots of normal Mercurial users do things like create one-off shell scripts for common workflows that I think this is useful enough to be in the install (as opposed to, say, a wiki page - which most users will likely never find). This text is by no means perfect. But you have to start somewhere. I think I did cover the important parts, though.

transplant: restore dirstate correctly at unexpected failure Before this patch, transplant can't restore dirstate as expected at failure other than one while patching. This causes: - unexpected file status - dirstate refers already rollback-ed parent (only at failure of transplanting the 2nd or later revision) To restore dirstate correctly also at unexpected failure, this patch encloses scope of store lock and transaction by 'dirstateguard'. This is temporary fixing for stable branch. See DirstateTransactionPlan wiki page for detail about the future plan to treat dirstate consistently around scope boundary of transaction. https://mercurial.selenic.com/wiki/DirstateTransactionPlan This patch also adds 'if lock' examination for safety 'lock.release()', because creating 'dirstateguard' object may fail unexpectedly (e.g. IOError for saving dirstate). BTW, in the test script, putting section header '[extensions]' into '.hg/hgrc' is needed to fix incomplete disabling 'abort' extension at 4d1382fd96ff.

localrepo: make journal.dirstate contain in-memory changes before transaction Before this patch, in-memory dirstate changes aren't written out at opening transaction, even though 'journal.dirstate' is created directly from '.hg/dirstate'. Therefore, subsequent 'hg rollback' uses incomplete 'undo.dirstate' to restore dirstate, if dirstate is changed and isn't written out before opening transaction. In cases below, the condition "dirstate is changed and isn't written out before opening transaction" isn't satisfied and this problem doesn't appear: - "wlock scope" and "transaction scope" are almost equivalent e.g. 'commit --amend', 'import' and so on - dirstate changes are written out before opening transaction e.g. 'rebase' (via 'dirstateguard') and 'commit -A' (by separated wlock scopes) On the other hand, 'backout' may satisfy the condition above. To make 'journal.dirstate' contain in-memory changes before opening transaction, this patch explicitly invokes 'dirstate.write()' in 'localrepository.transaction()'. 'dirstate.write()' is placed before not "writing journal files out" but "invoking pretxnopen hooks" for visibility of dirstate changes to external hook processes. BTW, in the test script, 'touch -t 200001010000' and 'hg status' are invoked to make file 'c' surely clean in dirstate, because "clean but unsure" files indirectly cause 'dirstate.write()' at 'repo.status()' in 'repo.commit()' (see fe03f522dda9 for detail) and prevents from certainly reproducing the issue.

dirstate: ensure mv source is marked deleted when walking icasefs (issue4760) Previously, importing a case-only rename patch on a case insensitive filesystem caused the original file to be marked as '!' in status. The source was being forgotten properly in patch.workingbackend.close(), but the call it makes to scmutil.marktouched() then put the file back into the 'n' state (but it was still missing from the filesystem). The cause of this was scmutil._interestingfiles() would walk dirstate, and since dirstate was able to lstat() the old file via the new name, was treating this as a forgotten file, not a removed file. scmutil.marktouched() re-adds forgotten files, so dirstate got out of sync with the filesystem. This could be handled with less code in the "kind == regkind or kind == lnkkind" branch of dirstate._walkexplicit(), but this avoids filesystem accesses unless case collisions occur. _discoverpath() is used instead of normalize(), since the dirstate case is given first precedence, and the old file is still in it. What matters is the actual case in the filesystem.

extdiff: allow modifications in subrepos to be copied back This check was a legacy bit from when the file data was being fetched manually with 'ctx[wfn]', but archive() does that now. 49966b5ab16f seems to indicate that this avoided a problem where a merge adds a file to another branch, and that test still passes. Unfortunately, I don't see a way to create a test that modifies the file in the temporary directory before the command exits. I wonder if the os.lstat() call needs to be wrapped in an exception handler for the case where archive didn't create a file because the file didn't exist in that revision. But I wasn't able to trigger a problem without it on a real repository.

ignore: fix path concatenation of .hgignore on Windows Since 3de48ff62733, .hgignore is ignored on Windows because a pat may have a drive letter, but pathutil.join is posixpath.join. "z:\foo\bar/z:\foo\bar\.hgignore" Instead, this patch uses os.path.join() and util.localpath() to process both parts as file-system paths. Maybe we can remove os.path.join() at dirstate._ignore because 'include:' is resolved relative to repo root? It was introduced by a04c7b74b3d5.

repair: fix typo in warning message

monoblue: link to branches on summary page "Tags" and "Bookmarks" sections on this page already have the similar links, and so does the "Branches" on summary page in gitweb, so let's do the same in monoblue.

monoblue: fix branches link on help topics page

hgweb: show ages in repos' Last modified column in monoblue and gitweb Index page, which shows the list of available repositories, has a column where the last modification date for each repo is shown. paper, coal and spartan already show the dates in relative format (e.g. "2 weeks ago"), because these styles have the required process_dates() js function call in their footer templates, which are included on every page. But monoblue and gitweb styles have more things in the footer templates, such as repo name and its atom/rss links, so they don't include the footer on index page (as this page doesn't have a single repo context). Let's call process_dates() without including the footer.

ignore: fix include: rules depending on current directory (issue4759) When reading pattern files, we just call open(path), which is relative to the current directory. Let's fix this by resolving the paths before attempting to read the file.
