templater: fix check-code error

smtp: verify the certificate of the SMTP server for STARTTLS/SMTPS Before this patch, the certificate of the SMTP server for STARTTLS or SMTPS isn't verified. This may cause man-in-the-middle security problem (stealing authentication information), even though SMTP channel itself is encrypted by SSL. When "[smtp] tls" is configured as "smtps" or "starttls", this patch: - uses classes introduced by preceding patches instead of "SMTP" or "SMTP_SSL" of smtplib, and - verifies the certificate of the SMTP server, if "[smtp] verifycert" is configured as other than False "[smtp] verifycert" can be configured in 3 levels: - "strict": This verifies peer certificate, and aborts if: - peer certification is not valid, or - no configuration in "[hostfingerprints]" and "[web] cacerts" This is default value of "[smtp] verifycert" for security. - "loose": This verifies peer certificate, and aborts if peer certification is not valid. This just shows warning message ("certificate not verified"), if there is no configuration in "[hostfingerprints]" and "[web] cacerts". This is as same as verification for HTTPS connection. - False(no verification): Peer certificate is not verified. This is as same as the behavior before this patch series. "hg email --insecure" uses "loose" level, and ignores "[web] cacerts" as same as push/pull/etc... with --insecure. Ignoring "[web] cacerts" configuration for "hg email --insecure" is already done in "dispatch._dispatch()" by looking "insecure" up in the table of command options.

sslutil: abort if peer certificate is not verified for secure use Before this patch, "sslutil.validator" may returns successfully, even if peer certificate is not verified because there is no information in "[hostfingerprints]" and "[web] cacerts". To prevent from sending authentication credential to untrustable SMTP server, validation should be aborted if peer certificate is not verified. This patch introduces "strict" optional argument, and "sslutil.validator" will abort if it is True and peer certificate is not verified.

smtp: add the class to verify the certificate of the SMTP server for SMTPS Original "smtplib.SMTP_SSL" has no route to pass "ca_certs" and "cert_reqs" arguments to underlying SSL socket creation. This causes that "getpeercert()" on SSL socket returns empty dict, so the peer certificate for SMTPS can't be verified. This patch introduces the "SMTPS" class derived from "smtplib.SMTP" to pass "ca_certs" and "cert_reqs" arguments to underlying SSL socket creation. "SMTPS" class is derived directly from "smtplib.SMTP", because amount of "smtplib.SMTP_SSL" definition derived from "smtplib.SMTP" is as same as one needed to override it. This patch defines "SMTPS" class, only when "smtplib.SMTP" class has "_get_socket()" method, because this makes using SSL socket instead of normal socket easy. "smtplib.SMTP" class of Python 2.5.x or earlier doesn't have this method. Omitting SMTPS support for them is reasonable, because "smtplib.SMTP_SSL" is already unavailable for them before this patch. Almost all code of "SMTPS" class is imported from "smtplib.SMTP_SSL" of Python 2.7.3, but it differs from original code in point below: - "ssl.wrap_socket()" is replaced by "sslutil.ssl_wrap_socket()" for compatibility between Python versions

smtp: add the class to verify the certificate of the SMTP server for STARTTLS Original "smtplib.SMTP" has no route to pass "ca_certs" and "cert_reqs" arguments to underlying SSL socket creation. This causes that "getpeercert()" on SSL socket returns empty dict, so the peer certificate for STARTTLS can't be verified. This patch introduces the "STARTTLS" class derived from "smtplib.SMTP" to pass "ca_certs" and "cert_reqs" arguments to underlying SSL socket creation. Almost all code of "starttls()" in this class is imported from "smtplib.SMTP" of Python 2.7.3, but it differs from original code in points below: - "self.ehlo_or_helo_if_needed()" invocation is omitted, because: - "ehlo_or_helo_if_needed()" is available with Python 2.6 or later, and - "ehlo()" is explicitly invoked in "mercurial.mail._smtp()" - "if not _have_ssl:" check is omitted, because: - "_have_ssl" is available with Python 2.6 or later, and - same checking is done in "mercurial.sslutil.ssl_wrap_socket()" - "ssl.wrap_socket()" is replaced by "sslutil.ssl_wrap_socket()" for compatibility between Python versions - use "sock.recv()" also as "sock.read()", if "sock" doesn't have "read()" method with Python 2.5.x or earlier, "sslutil.ssl_wrap_socket()" returns "httplib.FakeSocket"-ed object, and it doesn't have "read()" method, which is invoked via "smtplib.SSLFakeFile".

sslutil: try harder to avoid getpeercert problems We wrap both calls to getpeercert in a try/except to make sure we catch its bogus AttributeError.

copies._forwardcopies: use set operations to find missing files This is a performance win for a number of reasons: - We don't iterate over contexts, which avoids a completely unnecessary sorted call + the O(number of files) abstraction cost of doing that. - We don't check membership in a context, which avoids another O(number of files) abstraction cost. - We iterate over the manifests in C instead of Python. For a large repo with 170,000 files, this improves perfpathcopies from 0.34 seconds to 0.07. Anything that uses pathcopies, such as rebase or diff --git between two revisions, benefits.

perf: add a command to test copies.pathcopies perf An upcoming patch will improve the performance of this function, and this command will be used to demonstrate that improvement.

scmutil.addremove: use iteritems on walk results Now that we no longer sort all the walk results, using iteritems becomes possible. This is a relatively minor speedup: on a large repository with 170,000 files, perfaddremove goes from 2.13 seconds to 2.10.

scmutil.addremove: stop sorting all walk results The only place where the order matters is in printing out added or removed files. We already sort that set. On a large repository with 170,000 files, this speeds up perfaddremove from 2.34 seconds to 2.13.

scmutil.addremove: pull ui.status printing out of the loop This will let us stop sorting all the results in an upcoming patch. This also permits future refactorings where the same code consumes dirstate.walk results but doesn't print anything out. An argument could be made that printing out results as we go along is more responsive UI-wise. However, at this point iterating through walk results is actually faster than sorting them, so once we stop sorting all the results the argument ceases to be valid.

scmutil.addremove: remove redundant directory and symlink checks dirstate.walk only does lstats and never returns stat objects for directories. On a large repository with 170,000 files, this speeds perfaddremove up from 2.40 seconds to 2.34.

commands: fix typo in debugobsolete docstring

duplicatecopies: do not mark items not in the dirstate as copies Consider the following repo: 0 -- 1 (renames a to b) \ - 2 If we're rebasing 2 onto 1, then duplicatecopies is called with arguments (2, 1). copies.pathcopies goes backwards from 1 to 0 and returns the pair dst = a, src = b. Of course, since we're working on top of 2, at this point a doesn't exist in the dirstate. Extra entries in the copymap are currently harmless because the copymap is only queried for items in the dirstate map. However, if the dirstate.copy method becomes one of the sources used to determine which files have changed, this will prove problematic. Note that we can't avoid going backwards in general -- consider this repo: 0 -- 1 (renames a to b) \ - 2 (renames a to c) Rebasing 2 onto 1 should produce a rename from b to c.

duplicatecopies: fix arg name and docstring While most callers do indeed use duplicatecopies with a rev and its parent, rebase doesn't.

pull: list bookmarks before pulling changesets (issue3873) Consider a bookmark B that exists both locally and remotely. If B is updated remotely, and then a pull is performed where the pull set contains the new location of B, the bookmark is updated locally. However, if remote B is updated in the middle of a pull to a location not in the pull set, the bookmark won't be updated locally at all. To fix this, list bookmarks before pulling in changesets, not after. This still leaves a race open if B gets moved in between listing bookmarks and pulling in changesets, but the race window is much smaller. Fixing the race properly would require a bundle format upgrade. test-hook.t's output changes because we no longer do two listkeys calls during pull, just one. test-pull-http.t's output changes because we now search for bookmarks before searching for changes.

test-hook.t: remove prelistkeys.forbid hook before moving on An upcoming patch will change the order of operations and perform a listkeys before a changegroup fetch. This will cause a few tests to print out the wrong error message.

bookmarks.updatefromremote: rename local rb to remotemarks This local will become a parameter in an upcoming patch, so give it a more descriptive name. The name stays similar to the existing localmarks.

check-code: extract windows glob warning message it will be used often

blackbox: defer opening a log file until needed (issue3869) Previously, we opened the log file when creating a repo object. This was inefficient (not all repo creation is going to result in a need to log something), but more importantly it broke subrepo updates when used on NFS. * perform an update in the master repo that triggers a subrepo clone * empty subrepo already exists, and has an open, empty blackbox.log file due to it being opened eagerly/prematurely * hg decides to blow away the skeletal subrepo (see use of shutil.rmtree in subrepo._get) * we crash, due to NFS treating a delete of an open file as really a rename to a hidden ".nfs" file Now that we open the blackbox log file on demand, no file exists at the time the empty subrepo is deleted, so the above problem does not occur.

patch: match 'diff --git a/' instead of 'diff --git' This reduces the likelihood of a traceback when trying to email a patch that happens to have 'diff --git' at the beginning of a line in the description, as this patch did: http://markmail.org/message/wxpgowxd7ucxygwe

hgweb: do not pass on repo.ui when recreating a repo Recreate the repo with the global configuration in repo.baseui. The repo configuration is reread anyway. And now deleted repo configuration is reset to the default value.

repo: repo isolation, do not pass on repo.ui for creating new repos A repo should not get the configuration from an other repo, so create it with the global configuration in repo.baseui. This is done too when recreating a repo. The repo configuration is reread anyway. And now deleted repo configuration does not persist.

manifestmerge: drop redundant flags calls

manifestmerge: use dicthelpers.diff and join This patch improves manifestmerge performance significantly. In a repository with 170,000 files, the following results were observed on a clean working directory. Revision '.' adds one file. hg perfmergecalculate -r . - before: 0.41 seconds - after: 0.13 seconds hg perfmergecalculate -r .^ - before: 0.53 seconds - after: 0.24 seconds Comparing against '.' is much faster than comparing against '.^' because with '.', the wctx and p2 manifest strings have the same identity, so comparisons are simply pointer equality. With '.^', the strings have different identities so we need to perform memcmps. Any operation that uses manifestmerge benefits. - hg update . goes from 2.04 seconds to 1.75 - hg update .^ goes from 2.52 seconds to 2.25 - hg rebase -r . -d .~6 (involves 4 merges) goes from 11.8 seconds to 10.8

manifestdict: add a method to diff _flags This will be used in an upcoming patch.

mercurial: implement diff and join for dicts Given two dicts, diff returns a dict containing all the keys that are present in one dict but not the other, or whose values are different between the dicts. The values are pairs of the values from the dicts, with missing values being represented as an optional argument, defaulting to None. Given two dicts, join performs what is known as an outer join in relational database land: it returns a dict containing all the keys across both dicts. The values are pairs as above, except they aren't compared to see if they're the same.

convert: add closesort algorithm to mercurial sources If you actively work with branches, sometimes you need to close old branches which last commited hundreds revisions ago. After close you will see long lines in graph visually spoiling history. This sort only moves closed revisions as close as possible to parents and does not increase storage size as datesort do.

manifestmerge: rename n to n1 and n2 An upcoming patch will combine the two loops into one, so it's important to distinguish between nodes in m1 and nodes in m2.

hgk: fix a pyflakes error

dirstate.walk: fast path none-seen + match-always case for step 3 This case is a common one -- e.g. `hg diff`. For a repository with 170,000 files, this speeds up perfstatus from 0.95 seconds to 0.88.

dirstate.walk: fast path match-always case during traversal This case is a common one -- e.g. `hg status`. For a repository with 170,000 files, this speeds up perfstatus --unknown from 2.15 seconds to 2.09.

largefiles: fix _always for match overrides Upcoming patches will speed dirstate.walk up by not filtering based on the match function when match.always() is True. For that to work, match.always() needs to be accurate. Previously it wasn't so for largefiles.

dirstate.walk: remove subrepo and .hg from results before step 3 An upcoming patch will speed dirstate.walk up by not querying the results dict when it is empty. This ensures it is in some common cases. This should be safe because subrepos and .hg aren't part of the dirstate.

blackbox: account for another source of errors

hgk: remove regsub, split on \r instead No need to regsub all \r\n's to \n's, we can just split on \r as well; this may produce extra empty elements in the list, but they won't match anyway.

hgk: simplify tags parser As when hg tags is being called without -v option, it returns lines with two elements in each, we can just interate them as if it were a usual Tcl list using foreach and two variables. Line endings and whitespace don't matter when doing so, so we may keep them as is. When we're processing the lines, tag variable is assigned a tag name, and rev is a string in form of revision:hash which we can split on colon. As Tcl8.4 lacks lassign command, and using lindex makes code a bit less readable, we use foreach to iterate over two-element list.

hgk: add support for phases Add support for phases. Update tests.

hgk: in popups, replace labels with window titles Replace labels with window titles. That also requires to change grid placement manager settings to compensate padding which used to be applied to now non-existent labels.

hgk: update backgroud colour when Ttk is available Ttk doesn't automatically set up Tk colour palette. Because of that, Ttk controls look differently when used together with old Tk controls. When we use Ttk controls, we first query if we have any setting for the client background, and if we do, we update Tk palette as well.

hgk: fix pop-up windows Create pop-up windows properly so they go to the floating layer in tiling window managers.

hgk: don't use fixed format for dates Don't pass -format with a date format string, use default instead so users can use their own preferences.

test-completion: test completion of tags

debugpathcomplete: satisfy the code checker

tests: test debugpathcomplete and debuglabelcomplete

tests: rename test-debugcomplete.t to test-completion.t

pathcomplete: complete directories more conservatively Suppose we want to perform a single-level completion (i.e. without --full) of "fi" in a repo containing "fee", "fie/dead", "fie/live", and "foe". If we give back "fie/" as the only answer, the shell will consider the completion to be unambiguous, and will append a space after the completion. We can't complete "fie/live" or "fie/dead" without first backspacing over that space. We used to thus create two fake names, "fie/a" and "fie/b", to force the shell to consider the completion to be ambiguous. It would then stop at "fie/" without appending a space, allowing us to hit tab again to complete "fie/live" or "fie/dead". The change here arises from realising that we only need to force the shell to consider a completion as ambiguous if we have exactly one directory and zero files as possible completions. This prevents spurious names from showing up as possible completions when they don't need to be invented in the first place.

sadclown: another test failure eluded me

bash_completion: recognize normal command abbreviations In many common cases, this eliminates a call to "hg help" to get a complete command name, thus improving responsiveness.

completion: selectively use debugpathcomplete in bash_completion The current bash_completion code can be very slow in a large working directory. It always uses "hg status" to generate possibly matching files, which checks the status of every file. We often don't care about status when completing, so that cost is very high. As the new debugpathcomplete command does not check the status of files, it offers much better performance for commands that only care about completing names.

completion: add a debugpathcomplete command The bash_completion code uses "hg status" to generate a list of possible completions for commands that operate on files in the working directory. In a large working directory, this can result in a single tab-completion being very slow (several seconds) as a result of checking the status of every file, even when there is no need to check status or no possible matches. The new debugpathcomplete command gains performance in a few simple ways: * Allow completion to operate on just a single directory. When used to complete the right commands, this considerably reduces the number of completions returned, at no loss in functionality. * Never check the status of files. For completions that really must know if a file is modified, it is faster to use status: hg status -nm 'glob:myprefix**' Performance: Here are the commands used by bash_completion to complete, run in the root of the mozilla-central working dir (~77,000 files) and another repo (~165,000 files): All "normal state" files (used by e.g. remove, revert): mozilla other status -nmcd 'glob:**' 1.77 4.10 sec debugpathcomplete -f -n 0.53 1.26 debugpathcomplete -n 0.17 0.41 ("-f" means "complete full paths", rather than the current directory) Tracked files matching "a": mozilla other status -nmcd 'glob:a**' 0.26 0.47 debugpathcomplete -f -n a 0.10 0.24 debugpathcomplete -n a 0.10 0.22 We should be able to further improve completion performance once the critbit work lands. Right now, our performance is limited by the need to iterate over all keys in the dirstate.

tests: add new command to test-debugcomplete

completion: add a debuglabelcomplete command When completing a "label" (a symbolic name for a commit), the bash_completion script currently has to invoke hg three times. For a large repository, the cost of starting up and loading all the necessary context over and over is very high. For instance, in mozilla-central: time (export HGPLAIN=1; hg tags -q; hg bookmarks -q; hg branches) >/dev/null 0.446 sec Compare with the debuglabelcomplete command that this commit adds: time hg debuglabelcomplete >/dev/null 0.148 sec This greatly helps responsiveness.

bash_completion: nuke a duplicated function

run-tests: only sort files when not given as argument os.listdir returns the files in any order. This has to be sorted. But when given as argument, the user should be allowed to set any order. This restores the behaviour before 9848a94e2a.

blackbox: use util.getuser for portability On Windows, our implementation is more robust than Python's version.

blackbox: prevent failed I/O from causing hg to abort Instead, we simply print a warning message if opening the blackbox log file fails, or if writing to it fails.

largefiles: don't query the dirstate for key None lfutil.splitstandin(f) can be None, and we query the dirstate for that without checking if it is. This will cause problems with the upcoming move to critbit- based dicts, since they only support strings as keys.

merge

bookmarks: moving the active bookmark deactivates it After this change, moving the active bookmark somewhere other than the current changeset (i.e., with --rev) deactivates it. Previously it would remain in .hg/bookmarks.current, which seems like a bug.

bookmarks: allow (re-)activating a bookmark on the current changeset Allow a bookmark that points to the current changeset to be made the active bookmark without requiring --force. Previously, this would've aborted with: abort: bookmark 'Z' already exists (use -f to force)

applyupdates: assign variable before we try to use it (issue3855) The variable 'fd' was getting used with a value left over from a prior iteration, causing a KeyError: '.hgsubstate'.

revset: don't abort when regex to tag() matches nothing (issue3850) This makes the tag("re:...") revset consistent with branch("re:...").

rebase: fix --collapse when a file was added then removed When a series of commits first adds a file and then removes it, hg rebase --collapse prompts whether to keep the file or delete it. This is due to it reusing the branch merge code. In a noninteractive terminal it defaults to keeping the file, which results in a collapsed commit that is has a file that should be deleted. This bug resulted in developers accidentally commiting unintentional changes to our repo twice today, so it's fairly important to get fixed. This change allows rebase --collapse to tell the merge code to accept the latest version every time without prompting. Adds a test as well.

hgweb: change manifest archive links to only archive the current directory When the web server shows the manifest for a single, non top directory, append the path to the directory to the archive links. This makes the web server generate archive files that only include the current directory (and its subdirectories). Note that archive links in other pages (e.g. changeset) or at the top of the manifest are unchanged. Directory archive links have an extra "/" at the end which does not impact the result of the archive operation. Keeping it there made the implementation of this feature simpler.

hgweb: teach archive how to download a specific directory or file The archive web command now takes into account the "file" request entry, if one is provided. The provided "file" is processed as a "path" corresponding to a directory or file that will be downloaded. With this change hgweb can to process requests such as: http://mercurial.selenic.com/hg/archive/tip.zip/mercurial/templates This will download all files on the mercurial/templates directory as a zip file. It is not possible to specify file patterns ('glob', 'relglob', 'path', 'relpath', 're', 'relre' nor 'set'). The server will reject those with a 403 HTTP error response. Note that this is a first step to add support for downloading directories from the web interface. A following patch will modify the archiveentry map entry on the different templates so that it adds the current folder path to the archive links.

test-archive: gracefully handle HTTPErrors on get-with-headers This avoids pritting out a traceback when a get-with-headers call causes hgweb to respond with an HTTPError code.

bash_completion: tell an editor what type of file this is

bash_completion: allow remove to complete normal files Previously, we only completed files that had already been manually deleted. That behaviour made no sense. We now complete unmodified, modified, and deleted files.

bash_completion: match more narrowly This greatly helps completion performance for most commands that deal with files. In a working dir with 150,000 files, where we want to complete the name of a modified file under a path beginning with "a", from the root of the working dir: (old) hg status -nm . 1.7 sec (new) hg status -nm "glob:a**" 0.3 Even "hg add" becomes a little faster, in spite of being the worst case (matching untracked files).

strip: make --keep option not set all dirstate times to 0 hg strip -k was using dirstate.rebuild() which reset all the dirstate entries timestamps to 0. This meant that the next time hg status was run every file was considered to be 'unsure', which caused it to do expensive read operations on every filelog. On a repo with >150,000 files it took 70 seconds when everything was in memory. From a cold cache it took several minutes. The fix is to only reset files that have changed between the working context and the destination context. For reference, --keep means the working directory is left alone during the strip. We have users wanting to use this operation to store their work-in-progress as a commit on a branch while they go work on another branch, then come back later and be able to uncommit that work and continue working. They currently use 'git reset HARD^' to accomplish this in git.

sshpeer: store subprocess so it cleans up correctly When running 'hg pull --rebase', I was seeing this exception 100% of the time as the python process was closing down: Exception TypeError: TypeError("'NoneType' object is not callable",) in <bound method Popen.__del__ of <subprocess.Popen object at 0x937c10>> ignored By storing the subprocess on the sshpeer, the subprocess seems to clean up correctly, and I no longer see the exception. I have no idea why this actually works, but I get a 0% repro if I store the subprocess in self.subprocess, and a 100% repro if I store None in self.subprocess. Possibly related to issue 2240.

blackbox: fix exception when logging commands with format characters When running commands like 'hg export -o mypatch-%N.patch', the blackbox would throw an exception because it tried to format %N. This change prevents it from trying to format the command string.

localrepo: always write the filtered phasecache when nodes are destroyed (issue3827) When the strip command is run, it calls repo.destroyed, which in turn checks if we read _phasecache, and if we did calls filterunknown on it and flushes the changes immediately. But in some cases, nothing causes _phasecache to be read, so we miss out on this and the file remains the same on-disk. Then a call to invalidate comes, which should refresh _phasecache if it changed, but it didn't, so it keeps using the old one with the stripped revision which causes an IndexError. Test written by Yuya Nishihara.

rebase: restore active bookmark after rebase --continue When a rebase has conflicts and the user uses rebase --continue, the previously active bookmark was not being made active once again. With this change that bookmark is made active again, just as if the rebase had never been interrupted. This changes the rebasestate file format, but should handle old formats correctly. Since the file is transient, this is even less of a problem. Adds a test to verify the new behavior. I manually tested continuing rebases with and without an active bookmark, and with and without being on the bookmark being rebased.

setup.py: ignore warnings from obsolete Fix version detection with recent hg versions.

setup.py: add metadata to register package to PyPI This allows updating PyPI with just 'setup.py register' (assuming the user is an owner or maintainer of the PyPI package).

httppeer: avoid large dumps when we don't see an hgweb repo When we don't get an hgweb protocol response, we dump the response to the user for diagnostic purposes (it might be a cgitb message, for instance). But if we try to clone a bundle, we don't want to show the entire bundle in the error message. Also, we don't want fetch the full bundle multiple times during fallback. So we only fetch 1k here.

httppeer: improve protocol check Pre-0.6c hgweb used text/plain for protocol responses. This meant that a web server could serve a static file and confuse a client into generating a nasty traceback. Now we insist that text/plain protocol responses not include a Content-Length, which older hgweb didn't generate but will typically be produced for static files.

util: add a timed function for use during development I often want to measure the cost of a function call before/after an optimization, where using top level "hg --time" timing introduces enough other noise that I can't tell if my efforts are having an effect. This decorator allows a developer to measure a function's cost with finer granularity.

largefiles: remove wrong comment on standin matcher and code for creating dirs The existence of these directories could not be relied on anyway and all dependencies on them should have been removed.

merge with stable

templatefilters: add missing import of _

largefiles: updatelfiles should use working dir standins, not standins from p1 This makes a difference when working directory is dirty, especially when merging with a revision for which we don't have largefiles.

largefiles: simplify cachelfiles - don't spend a lot of time checking hashes cachelfiles jumped through loops to handle merges and modified files ... but it did apparently no longer have a valid reason to do so. It should just always make sure that the largefiles referenced from the standins are present - no matter which actual largefile is stored in the working directory. If there is no standin then there is nothing to fetch. The old code usually verified the hash of all largefiles every time this function was invoked - for examply by 'update'. This change makes a trivial noop update 5-10 seconds faster on our repo (with the other 50% spent doing another unnecessary hashing of all largefiles).

largefiles: don't let update leave wrong largefiles in wd if fetch fails Situations where a largefile for some reason wasn't available sometimes caused wrong largefile content and state. It has mostly been seen when interrupting download of largefiles ... and when introducing programming errors. Instead we now make sure to delete the old and wrong largefile. A missing file is a well-known error condition and much more reasonable way to handle the situation.

largefiles: missing largefiles should not be committed as removed Largefiles can easily become missing - for example if it simply isn't available or the download fail. It might even be convenient to be able to work that way in some cases. But commiting missing largefiles as if they had been 'hg remove'd is plain wrong.

largefiles: don't assume that .hg/largefiles/ still exists It might not have been created and it might have been removed.

largefiles: getstandinmatcher should not depend on existence of directories Looking for a (potentially empty) directory was not reliable - both because it is a reasonable assumption that empty directories can be removed and because it wasn't created in all cases ... such as when pulling to an existing repository.

tests: don't rely on broken behaviour in test-largefiles-cache.t The test relied on the bug that 'pull largefiles from branchheads' didn't pull any largefiles from tip revision when it seemed like no largefiles had been checked out before.

largefiles: fix download of largefiles from an empty list of changesets The empty list was interpreted as all revisions - just like None is. The empty list is now handled explicitly.

largefiles: fix off-by-one error on pull --all-largefiles Test output is changed in a case where one revision was pulled, but because of the off-by-one error it thought that 0 revisions were pulled ... and because of another bug it thus (tried to) fetch largefiles for all revisions. After this change it no longer reports failure when it failed while trying to fetch largefiles it shouldn't fetch. Largefiles that it shouldn't fetch but managed to fetch anyway will now correctly be missing later on. This change thus resolves some of unexplained test output introduced in 1e4eb1faba6e.

match: more accurately report when we're always going to match This improves the performance of log --patch and --stat by about 20% for moderately large manifests (e.g. mozilla-central) for the common case of no -I/-X patterns.

scmutil: fix NameError on windows Forgot to import util in mercurial.scmwindows. Error was introduced in: changeset: 18862:4c6f7f0dadab user: Kevin Bullock <kbullock@ringworld.org> date: Tue Feb 12 11:36:21 2013 -0600 summary: scmutil: split platform-specific bits into their own modules

commands: exit from the log loop at the right time Previously, we'd run the iterator one more time than necessary, potentially doing a lot of extra work in the process.

cmdutil: use a small initial window with --limit In a large repo, running a command like "log -l1 -p" was expensive because it would always traverse 8 commits, as 8 was the initial window size. We now choose the lesser of 8 or the limit, speeding up the "log -l1 -p" case by a factor of 5.

worker: handle worker failures more aggressively We now wait for worker processes in a separate thread, so that we can spot failures in a timely way, wihout waiting for the progress pipe to drain. If a worker fails, we recover the pre-parallel-update behaviour of failing early by killing its peers before propagating the failure.

worker: fix a race in SIGINT handling This is almost impossible to trigger due to the tiny time window involved.

worker: on error, exit similarly to the first failing worker Previously, if a worker failed, we exited with status 1. We now exit with the correct exit code (killing ourselves if necessary).

largefiles: don't cache largefiles for pulled heads by default After discussion, we've agreed that largefiles for newly pulled heads should not be cached by default. The use case for this is using largefiles repos with multiple remote servers (and therefore multiple remote largefiles caches), where users will be pulling from non-default locations on a regular basis. We think this use case will be significantly less common than the use case where all largefiles are stored on the same central server, so the default should be no caching. The old behavior can be obtained by passing the --cache-largefiles flag to pull.

bundle: treat branches created newly on the local correctly (issue3828) Before this patch, "hg bundle --branch foo other" fails to create bundle file, if specified "foo" branch is created newly on the local repository. "hg bundle" uses "hg.addbranchrevs(repo, other, ...)" to look branch names up, even though other outgoing-like implementation uses "hg.addbranchrevs(repo, repo, ...)". In the former invocation, "other" repository recognizes such branches as unknown, so execution is aborted. This patch uses "hg.addbranchrevs(repo, repo, ..)" in "hg bundle" to bundle revisions on such branches correctly.

mergetools: refine vimdiff warning message We explicitly redraw before echoing the message so that it simply displays at the bottom of the window. Also simplifies the message printing by using 'echomsg' (which uses 'echohl' internally) and adds the names of the software involved for improved Googleability.

mergetools: vimdiff issue a warning explaining how to abort Adds a message displayed at each vimdiff invocation: merge conflict detected, type ":cq" to abort Vimdiff is very confusing for non-vim user (not to speak about vim user confused anyway.

dispatch: also a separate warning message on aliases with --config As mentioned in bug 2043, --config is also not supported in an alias. So report this the same way as the other "early" options. Example with alias.broken = stat --config a.config=1 Before: $ hg broken abort: Option --config may not be abbreviated! After: $ hg broken error in definition for alias 'broken': --config may only be given on the command line

extensions: remove erroneous comment We actually -do- use the 'ui' argument to print a debug statement.

blackbox: do not translate the log messages User 'timeless' in irc mentioned that having the blackbox be translated would result in logs that: - may be mixed language, if multiple users use the same repo - are not google searchable (since searching for english gives more results) - might not be readable by an admin if the employee is using hg in his native language And therefore we should log everything in english.

scmutil: split platform-specific bits into their own modules This parallels what's done for the util module, which imports either mercurial.posix or mercurial.windows as 'platform' and then slurps the appropriate functions into its own namespace.

backout: call cmdutil.commit directly instead of commands.commit This cleans up the messiness of having one command call another, and makes the backout command robust against changes to the commit command.

commit: factor out status printing into a helper function We create a new function commitstatus() in cmdutil that handles printing the status message(s) after a commit. This will allow other commit-like commands to use it, and in particular is step 2 towards removing backout's call to commands.commit.

backout: remove unnecessary dict copy This is step 1 to remove backout's call to commands.commit. We don't use the options again anywhere below except for backout's own purposes, specifically choosing a merge tool, so we just write the commit options in directly.

backout: remove unnecessary frobbing of addremove option There's no way for addremove to show up in backout's opts dictionary. It was being set manually because cmdutil.commit expected it to be there (and would throw an exception if it wasn't). This was fixed waaaaaaay back in: changeset: 5829:784073457a0f user: Kirill Smelkov <kirr@mns.spb.ru> date: Thu Jan 10 12:07:18 2008 +0300 summary: cmdutil.commit: extract 'addremove' from opts carefully

backout: use cmdutil.revert directly instead of commands.revert Before this change, backout would explicitly set the options it passed to commands.revert in order to fall thru most of its logic and call cmdutil.revert. This change makes it clearer what backup is trying to accomplish and makes it robust against changes to the revert command.

check-code: warn about line glob match with no glob character (?*/)

tests: remove glob from output lines containing no glob character

tests: inform on Windows about unnecessary glob lines When glob lines directly match on windows, "/" (and not "\") was output in the path on the line. No glob matching is necessary in this case. The test output will look like this (when 5 tests have passed and no 4 has an unnecessary glob): ... Info, unnecessary glob: info about some/thing (glob) ..

tests: quickly check if the glob line already matches the output This happens when a path with "/" as only glob char is matched on a non windows platform. (Currently one third of all glob matches.) The slowdown on windows and the speedup on other os are neglectable.

tests: append glob to filename output when required (windows) This lines were introduced in cd403d6d96ef and made the test fail on windows.

util: make ensuredirs safer against races

blackbox: only show new heads on incoming The blackbox was logging every head after every incoming group. Now we only log the heads that have changed. Added a test. Moved the hooks test to the bottom of the file since the hooks interfer with the tests after it.

blackbox: fix copyright

blackbox: fix a failing pyflakes test

blackbox: tests for the blackbox extension A few tests to cover the blackbox extension. Covers commands, hooks, and incoming changes.

blackbox: adds a 'blackbox' command for viewing recent logs Adds a 'hg blackbox' command for viewing the latest entries in the blackbox log. By default it shows the last 10 entries, but -l allows the user to specify.

blackbox: log incoming changes via ui.log() Logs incoming changes to a repo to ui.log(). Includes the number of changes and the hashes of the heads after the new changes. Example log line: 2013/02/09 08:35:19 durham> 1 incoming changes - new heads: cb9a9f314b8b Currently the blackbox logs the unix user that is performing the push/pull. It would be nice to log the http authorized user as well so it works with hgweb, but that's outside the scope of this commit.

blackbox: logs python and extension hooks via ui.log() Logs python and extension hooks to ui.log() for viewing in the blackbox. Example log lines: 2013/02/09 08:35:19 durham> pythonhook-preupdate: hgext.eol.preupdate finished in 0.01 seconds 2013/02/09 08:35:19 durham> exthook-update: echo hooked finished in 0.02 seconds

blackbox: log the commands that are run Uses ui.log to log which commands are run, their exit code, the time taken, and any unhandled exceptions thrown. Example log lines: 2013/02/09 08:35:19 durham> add foo 2013/02/09 08:35:19 durham> add exited 0 after 0.02 seconds Updates the progress tests because they use a mocked time.time() which these changes affect.

blackbox: adds a blackbox extension Adds a blackbox extension that listens to ui.log() and writes the messages to .hg/blackbox.log. Future commits will use ui.log() to log commands, unhandled exceptions, incoming changes, and hooks. The extension defaults to logging everything, but can be configured via blackbox.track to only log certain events. Log lines are of the format: "date time user> message" Example log line: 2013/02/09 08:35:19 durham> 1 incoming changes - new heads: d84ced58aaa

scmutil: create directories in a race-safe way during update With the new parallel update code, it is possible for multiple workers to try to create a hierarchy of directories at the same time. This is hard to trigger in general, but most likely during initial checkout. To deal with these races, we introduce a new ensuredirs function whose contract is to ensure that a directory hierarchy exists - it will ignore a failure that implies that the desired directory already exists.

test-atomictempfile: convert to unit test

tests: add a test runner utility that prints nothing when all tests pass This will be used to run tests through run-tests, which will expect no output for a unit test that passes successfully. The motivation for using unit tests instead of the current Python tests is that they don't require an output file for comparison and that they're easier to write because of the available tools from unittest (setup, asserts).

hgweb: consistent author name width Paper & coal use a sligtly shorter name length of 12em in the log view than gitweb's 15em. Names too long for 12em is not entirely unheard of, and hence increasing the length is appropriate; hgweb should remain usable on 1024x768.

dirstate: fix generator/list error when using python 2.7 util.statfiles returns a generator on python 2.7 with c extensions disabled. This caused util.statfiles(...) [0] to break in tests. Since we're only stat'ing one file, I just changed it to call lstat directly.

mq: comply with filtering when injecting fake tags (issue3812) mq was injecting fake tags whenever the revisions were accessible to the filtering level. This issue impacts hgweb since it's common to have "secret" mq patches. As secret changesets are filtered by hgweb, the tags computation could break.

commit: factor out post-commit cleanup into workingctx This pulls some of the logic for the cleanup that needs to happen after a commit has been made otu of localrepo.commit and into workingctx. This is part of a larger refactoring effort that will eventually allow us to perform some types of merges in-memory.

localrepo: use workingctx for validation in commit This changes localrepo.commit to use the workingctx it creates form the munged output of localrepo.status while running some precommit validation. Specifically, it uses functions that were already present on the workingctx. I believe this is a net readabilty improvement, and that this makes these lines consistent with the refactoring in a subsequent patch that pulls some of the validation logic into workingctx so that it can be reused elsewhere.

localrepo: create context used for actual commit earlier localrepo.commit creates a workingctx, calls self.status, does some munging on the changes status returns, does some validation on those changes, and then creates a new workingctx from the changes. This moves the creation of the new workginctx ahead of some validation, with the intention of refactoring some of that validation logic into the workingctx, so that it can be reused elsewhere.
