identify: rename 'changed' keyword -> 'dirty' I meant to do this before sending the initial templater support, but forgot. I'm quite surprised that 'dirty' doesn't occur in more user facing contexts, but there are a few, like the help for blackbox. It also more obviously mirrors the '(clean)' state printed by the summary command. I also didn't like that it was just one letter off from {changes} in the {latesttags} sub-keywords, which has a totally different meaning.

dispatch: remove unused _loaded Now, there is no user for dispatch._loaded.

extensions: register functions always at loading extension (issue5601) Before this patch, functions defined in extensions are registered via extra loaders only in _dispatch(). Therefore, loading extensions in other code paths like below omits registration of functions. - WSGI service - operation across repositories (e.g. subrepo) - test-duplicateoptions.py, using extensions.loadall() directly To register functions always at loading new extension, this patch moves implementation for extra loading from dispatch._dispatch() to extensions.loadall(). AFAIK, only commands module causes cyclic dependency between extensions module, but this patch imports all related modules just before extra loading in loadall(), in order to centralize them. This patch makes extensions.py depend on many other modules, even though extensions.py itself doesn't. It should be avoided if possible, but I don't have any better idea. Some other places like below aren't reasonable for extra loading, IMHO. - specific function in newly added module: existing callers of extensions.loadall() should invoke it, too - hg.repository() or so: no-repo commands aren't covered by this. BTW, this patch removes _loaded.add(name) on relocation, because dispatch._loaded is used only for extraloaders (for similar reason, "exts" variable is removed, too).

identify: add template support This is based on a patch proposed last year by Mathias De Maré[1], with a few changes. - Tags and bookmarks are now formatted lists, for more flexible queries. - The templater is populated whether or not [-nibtB] is specified. (Plain output is unchanged.) This seems more consistent with other templated commands. - The 'id' property is a string, instead of a list. - The parents of 'wdir()' have their own list of attributes. I left 'id' as a string because it seems very useful for generating version info. It's also a bit strange because the value and meaning changes depending on whether or not --debug is passed (short vs full hash), whether the revision is a merge or not (one hash or two, separated by a '+'), the working directory or not (node vs p1node), and local or not (remote defaults to tip, and never has '+'). The equivalent string built with {rev} seems much less useful, and I couldn't think of a reasonable name, so I left it out. The discussion seemed to be pointing towards having a list of nodes, with more than one entry for a merge. It seems simpler to give the nodes a name, and use {node} for the actual commit probed, especially now that there is a virtual node for 'wdir()'. Yuya mentioned using fm.nested() in that thread, so I did for the parent nodes. I'm not sure if the plan is to fill in all of the context attributes in these items, or if these nested items should simply be made {p1node} and {p1rev}. I used ':' as the tag separator for consistency with {tags} in the log templater. Likewise, bookmarks are separated by a space for consistency with the corresponding log template.

show: show all namespaces in "work" view This commit addresses a number of deficiencies in `hg show work`'s output: * Failure to render tags (it just wasn't implemented) * Failure to render names associated with non-built-in namespaces (e.g. remotenames) * Color names were hardcoded instead of coming from the canonical source in the namespace This change has the intended effect of rendering tags and extra namespaces. It solves an immediate need at Mozilla of having names from a custom namespace printed, which is blocking us from switching from a custom `hg wip` revset/template combo to `hg show work`. Note that the order of branches and bookmarks changes. This is because bookmarks are registered before branches in namespaces.py. We may want to register them last, after tags and branches. Or we may want to added a weighted field to the namespace to control display order. Something to think about. I'm not a big fan of the complexity in the templating layer. There is a lot of code to basically filter out the special case of branch=='default' and tag=='tip'. Ideally, we would iterate over a data structure that had irrelevant/unwanted names pre-filtered. However, I wasn't sure how to best implement this. We probably want {namespaces} to emit everything (its current behavior). I was toying with the following: * {namespacesnondefaults} variation that filtered values * A filter function that operated on {namespaces} (I wasn't sure how to implement this since the filtering layer would see a "hybrid" instance as opposed to something that was definitely an iterable of namespaces.) * A namespaces(...) function where you could specify which values to return. I like this the most. But it really wants named arguments to control filtering and we only support named arguments on revsets, not templates. I figure perfect is the enemy of good and we can refine templating support for namespaces in the future. At least now we have a concrete example of a use case.

tests: add more tests for names rendering in `hg show work` This demonstrates some missing features. This will also help verify that a subsequent change has the intended effect.

namespaces: record and expose whether namespace is built-in Currently, the templating layer tends to treat each namespace as a one-off, with explicit usage of {bookmarks}, {tags}, {branch}, etc instead of using {namespaces}. It would be really useful if we could iterate over namespaces and operate on them generically. However, some consumers may wish to differentiate namespaces by whether they are built-in to core Mercurial or provided by extensions. Expected use cases include ignoring non-built-in namespaces or emitting a generic label for non-built-in namespaces. This commit introduces an attribute on namespace instances that says whether the namespace is "built-in" and then exposes this to the templating layer. As part of this, we implement a reusable extension for defining custom names on each changeset for testing. A second consumer will be introduced in a subsequent commit.

templatekw: expose color name in {namespaces} entries Templates make use of a "log.<namespace>" label. The <namespace> value here differs from the actual namespace name in that the namespace itself is plural but the label/color value is singular. Expose the color name to the templating layer so log.* labels can be emitted for {namespaces}. As part of this, we refactored the logic to eliminate a gnarly comprehension. We store color names in their own dict because the lookup can occur in tight loops and we shouldn't have to go to repo.names[ns] multiple times for every changeset.

show: construct changeset templater during dispatch Previously, we constructed a formatter from a specific template topic. Then from show() we reached into the internals of the formatter to resolve a template string to be used to construct a changeset templater. A downside to this approach was it limited us to having the entire template defined in a single entry in the map file. You couldn't reference other entries in the map file and this would lead to long templates and redundancy in the map file. This commit teaches @showview how to instantiate a changeset templater so we can construct a templater with full access to the map file. To prove it works, we've split "showwork" into components.

cmdutil: use named arguments for changeset_templater.__init__ This will make the API more extensible and easier to use.

bundle: inline applybundle1() We have now gotten rid of all but one caller, so let's inline it there.

bundle: make applybundle() delegate v1 bundles to applybundle1()

bundle: transpose transaction scope with bundle type switch This moves the transaction with-statements outside of the per-bundle-version switches, so the next patch will be a little simpler.

unbundle: move BundleUnknownFeatureError exception handling out This just moves the BundleUnknownFeatureError exception handling one level up so we collect the bundle2.applybundle{,1}() calls together. applybundle1() will never throw the exception, so it should have no functional consequence.

bundle: make applybundle1() return a bundleoperation See previous commit for motivation. It already lets us share a little bit more code in commands.py.

bundle: add a applybundle1() method This is one step towards removing a bunch of "if isinstance(gen, unbundle20)" by treating bundle1 and bundle2 more similarly. The name may sounds ironic for a method in the bundle2 module, but I didn't think it was worth it yet to create a new 'bundle' module that depends on the 'bundle2' module. Besides, we'll inline the method again later.

bundle: extract _processchangegroup() method The new method applies the changegroup and fills in op.records, sharing a little bit of code between the two callers. We'll add another caller soon.

bundle: make combinechangegroupresults() take a bundleoperation Both callers have a bundleoperation. Passing it in lets us share a bit more code.

bundle: move combineresults() from changegroup to bundle2 The results only need to be combined if they come from a bundle2. More importantly, we'll change its argument to a bundleoperation soon, and then it definitely will no longer belong in changegroup.py.

bundle: remove 'op' argument from applybundle() No callers pass in an operation.

test-rebase-conflicts: add a test case about turning obsstore on and off Turning obsstore and allowunstable on, rebase will skip the "can't remove original changesets with unrebased descendants" check. Then rebase could be interrupted (merge conflict), and the user has a chance to turn off obsstore. If rebase continues, the current code may strip irrelevant commits (in the test case added, "C" got stripped unexpectedly). The test case reproduces issue5606. It will be fixed by the "multidest" rebase refactoring being reviewed. The test case itself is relatively separate from the rebase refactoring, therefore sent separately hoping to reduce the number of patches of the main rebase series.

strip: include phases in bundle (BC) Before this patch, unbundling a stripped changeset would make it a draft (unless the parent was secret). This meant that one would lose phase information when stripping and unbundling secret changesets. The same thing was true for public changesets. While stripping public changesets is generally rare, it's done frequently by e.g. the narrowhg extension. We also include the phases in the temporary bundle, just in case stripping were to fail after that point, so the user can still restore the repo including phase information. Before this patch, the phases were left untouched during the bundling and unbundling of the temporary bundle. Only at the end of the transaction would phasecache.filterunknown() be called to remove phase roots that were no longer valid. We now need to call that also after the first stripping, i.e. before applying the temporary bundle. Otherwise unbundling the temporary bundle will cause a read of the phase cache which has stripped changesets in the cache and that fails. Like with obsmarkers, we unconditionally include the phases in the bundle when stripping (when using bundle2, such as when generaldelta is enabled). The reason for doing that for strip but not for bundle is that strip bundles are not meant to be shared outside the repo, so we don't care as much about compatibility.

bundle: add config option to include phases This adds an experimental.bundle-phases config option to include phase information in bundles. As with the recently added support for bundling obsmarkers, the support for bundling phases is hidden behind the config option until we decide to make a bundlespec v3 that includes phases (and obsmarkers and ...). We could perhaps use the listkeys format for this, but that's considered obsolete according to Pierre-Yves. Instead, we introduce a new "phase-heads" bundle part. The new part contains the phase heads among the set of bundled revisions. It does not include those in secret phase; any head in the bundle that is not mentioned in the phase-heads part is assumed to be secret. As a special case, an empty phase-heads part thus means that any changesets should be added in secret phase. (If we ever add a fourth phase, we'll include secret in the part and we'll add a version number.) For now, phases are only included by "hg bundle", and not by e.g. strip and rebase.

bundle2: record changegroup data in 'op.records' (API) When adding support for bundling and unbundling phases, it will be useful to have the list of added changesets. To do that, we return the list from changegroup.apply().

debugcommands: pass part, not read data, into _debugobsmarker() This matches how it's done for _debugchangegroup() and how we will soon do it for _debugphaseheads().

debugcommands: remove unused "all" argument from _debugobsmarkers

dagop: raise ProgrammingError if stopdepth < 0 revset.py should never send such a value.

make: add Debian 9 (Stretch) docker target

make: templatize Debian build target a la e63dfbbdbd07

make: add Ubuntu Zesty docker targets (.deb and ppa) Zesty Zapus was released on 2017-04-13 and will be supported until 2018-01.

docker: install less as a build-time dependency in deb-based distros It's needed since 387a76cac28e, otherwise dpkg-checkbuilddeps errors out.

py3: add utility to forward __str__() to __bytes__() It calls unifromlocal() instead of sysstr() because __bytes__() may contain locale-dependent values such as paths.

share: use dict literal instead of dict(key=value) check-code.py has the rule, but it isn't smart enough to catch this.

py3: use r'' to prevent conversion to bytes by transformer

py3: define __bytes__ for basefilectx class The implementation is shamely copied from the __str__ function

py3: check for bytes instead of str in isinstance

py3: convert kwargs' keys' to str using pycompat.strkwargs() On Python 3, we must have keys of keyword arguments as str.

py3: convert kwargs keys' back to bytes using pycompat.byteskwargs()

py3: use "%d" % val for int rather than pycompat.bytestr Earlier I used pycompat.bytestr() to convert integers to bytes, but we can do b"%d" % val to convert that int to bytes. b'' is already added by the transformer. Thanks to Yuya for suggesting this.

extensions: call afterloaded() with loaded=False for disabled extensions If an extension was loaded but disabled due to a minimumhgversion check it will be present in the _extensions map, but set to None. The rest of the extensions code treats the extension as if it were not present in this case, but the afterloaded() function called the callback with loaded=True.

fetch: remove shorthand of --edit colliding against -e/-ssh in remoteopts (BC) Before this patch, -e/--edit and -e/--ssh of fetch command collide against each other. This causes that -e is treated as shorthand of --edit but doesn't work as same as --edit. Therefore, -e works as neither --edit nor --ssh, in practice. This issue was introduced at 595a69a01129 (or 1.0), which renamed -f/--force-editor to -e/--edit. At that point, -e was already used as shorthand of --ssh. After this patch, -e is treated as shorthand of --ssh. This patch is marked as "(BC)", because -e as shorthand of --edit in existing scripts causes failure (or unexpected result) after this patch. This impact should be less enough, because --edit mainly focuses on interactive use. BTW, test-duplicateoptions.py (since 7d171c05a631 or 1.9) can't detect this kind of issues as expected, because direct invocation of extensions.loadall() doesn't involve registration of commands defined in extensions (this issue is fixed in subsequent patch).

releasenotes: improve parsing around bullet points Earlier, on parsing the bullet points from existing release notes the bullet points after the first one weren't written correctly to the notes file. This patch makes changes to parsereleasenotesfromfile() function that introduces a new bullet_points data structure that tracks the bullets and associated subparagraph. It also makes necessary changes to the tests related to merging of bullets.

bookmarks: factor method _printer out of for loop in printbookmarks This allows even further customization via extensions for printing bookmarks. For example, in hg-git this would allow printing remote refs by just modifying the 'bmarks' parameter instead of reimplementing the old commands.bookmarks method. Furthermore, there is another benefit: now multiple extensions can chain their custom data to bookmark printing. Previously, an extension could have conflicting bookmark output due to which loaded first and overrode commands.bookmarks. Now they can all play nicely together.

bookmarks: factor out bookmark printing from commands

commands: move activebookmarklabel to bookmarks module This is going to be used in an upcoming patch that moves more methods to bookmarks.py.

commands: replace locking code with a context manager Note that this means that we're unnecessarily creating a transaction in the pure "--inactive" (i.e. when deactivating the current bookmark), but that should be harmless.

bookmarks: factor out adding a list of bookmarks logic from commands We keep the lock in the caller so that future devs are aware of the locking implications.

bookmarks: factor out rename logic from commands We keep the lock in the caller so that future devs are aware of the locking implications.

bookmarks: factor out delete logic from commands We keep the lock in the caller so that future devs are aware of the locking implications.

revset: add startdepth limit to ancestors() as internal option This is necessary to implement the set{gen} (set subscript) operator. For example, set{-n} will be translated to ancestors(set, depth=n, startdepth=n). https://www.mercurial-scm.org/wiki/RevsetOperatorPlan#ideas_from_mpm The UI is undecided and I doubt if the startdepth option would be actually useful, so the option is hidden for now. 'depth' could be extended to take min:max range, in which case, integer depth should select a single generation. ancestors(set, depth=:y) # scan up to y-th generation ancestors(set, depth=x:) # skip until (x-1)-th generation ancestors(set, depth=x) # select only x-th generation Any ideas are welcomed. # reverse(ancestors(tip)) using hg repo 3) 0.075951 4) 0.076175

revset: add depth limit to ancestors() This is proposed by the issue5374, and will be a building block of set{gen} (set subscript) operator. https://www.mercurial-scm.org/wiki/RevsetOperatorPlan#ideas_from_mpm # reverse(ancestors(tip)) using hg repo 2) 0.075408 3) 0.075951

dagop: compute depth in revancestors() generator Surprisingly, this makes revset benchmark slightly faster. I don't know why, but it appears that wrapping -inputrev by tuple is the key. So I decided to just enable depth computation by default. # reverse(ancestors(tip)) using hg repo 1) 0.081051 2) 0.075408

dagop: just compare with the last value to deduplicate input of revancestors() Since we're using a max heap, the current rev should be a duplicate only if it equals to the previous one. We don't have to maintain the whole seen set. # reverse(ancestors(tip)) using hg repo 0) 0.086420 1) 0.081051

dagop: bulk rename variables in revancestors() generator - h -> pendingheap: "h" seems too short for variable of long lifetime - current -> currev: future patches will add current "depth" variable - parent -> prev or pctx: short lifetime, follows common naming rules

dagop: comment why revancestors() doesn't heapify input revs at once I wondered why we're doing this complicated stuff without noticing the input revs may be iterated lazily in descending order. c1f666e27345 showed why.

dagop: unnest inner generator of revancestors() This just moves iterate() to module-level function.

hgweb: plug followlines action in annotate view Add the followlines.js script and corresponding parameters as data attribute on <tbody class="sourcelines"> element. Extend CSS rules so that they also match the DOM structure of annotate view. As previously, only address paper and gitweb styles (other styles do not have followlines at all).

hgweb: parameterize the tag name of elements holding followlines selection While plugging followlines.js into "annotate" view, we'll need to walk a different DOM structure from that of "filerevision" view. In particular, the selectable source line element is a <tr> in annotate view (in contrast with a <span> in filerevision view). So make this tag name a parameter of followlines.js script by passing its value as a "selectabletag" data attribute of <pre class="sourcelines"> element. As <pre class="sourcelines"> tags are getting quite long in templates, rewrite them on several lines.

gitweb: wrap table rows of annotate view into a <tbody> element We will use this element to hook data attribute for the followlines.js script to be plugged in annotate view. Also this gets symmetrical with paper style which already has a <tbody> element.

tests: update regex check for fetch error in test-clonebundles.t On some systems, e.g. Docker container, the actual error may be: error fetching bundle: [Errno 99] Cannot assign requested address Update the regex to handle this case.

hgweb: use separate CSS class for navigation links in footer 2d93d2159e30 changed the styling of the "page_nav" CSS class to use flexbox to separate elements within the <div>. I didn't realize that this class was used outside of the links in the header. So this resulted in incorrectly formatting links in the footer of various pages. Fix that by introducing a new CSS class that preserves the old CSS behavior.

configitems: register 'ui.clonebundleprefers' as example for 'configlist' This exercise the default value handling in 'configlist'.

configitems: register 'patch.fuzz' as first example for 'configint' This exercise the default value handling in 'configint'.

configitems: issue a devel warning when overriding default config If the option is registered, there is already a default value available and passing a new one is at best redundant. So we issue a deprecation warning in this case. (note: there will be case were the default value will not be as simple as what is currently possible. We'll upgrade the configitems code to handle them in time.)

eol: fix 'error' parameter name in the commitctx wrapper Since its introduction in 9dfee83c93c8, the parameter has always been name "error". Yet the eol extension have been using 'haserror' as the argument name, breaking extensions with subclass passing 'error' as a keyword argument.

eol: import 'error' as 'errormod' We need the 'error' name available to fix another bug, so we rename the imported module.

configitems: register 'ui.quiet' as first example We now have a user and this works fine.

configitems: get default values from the central registry when available We do not have any registered config yet, but we are now ready to use them. For now we ignore this feature for config access with "alternates". On the long run, we expect alternates to be handled as "aliases" by the config item themself.

configitems: introduce a central registry for config option We now have the appropriate infrastructure to register config items. Usage will added in the next changeset.

configitems: add a basic class to hold config item information The goal of this class is allow explicit declaration for the available config option. This class will hold the data for one specific config item. To keep it simple we start centralizing the handling of the default config value. In the future we can expect more data to be carried on this class. For example: - documentation, - status (experimental, advanced, normal, deprecated), - aliases, - expected type, - etc...

run-tests: fix -i when "#testcases" is used in .t test The "#testcases" feature introduced by 7340465bd788 has issues with "-i" because "-i" uses "test.name.endswith('.t')" to test if a test is .t or not. test.name could now be something like "test-foo.t (caseA)" so the above endswith test is no longer valid. This patch changes the test to use "self.path" which won't have the issue.

run-tests: update .t reference output after reading the test The .t file is both test input and reference output. They should always match. However we have different code paths to read reference output (Test.__init__ -> Test.readrefout) and test input (TTest._run) so they might be inconsistent if somethings change the file between those two functions. This patch assigns "lines" read by "_run" back to "_refout" if "_refout" is not None (with --debug, see Test.readrefout) so reference output and test input will always match.

run-tests: do not prompt changes (-i) if a race condition is detected The race condition is like: 1. run-tests.py reads test-a.t as reference output, content A 2. run-tests.py runs the test (which could be content B, another race condition fixed by the next patch, but assume it's content A here) 3. something changes test-a.t to content C 4. run-tests.py compares test output (content D) with content A 5. with "-i", run-tests.py prompts diff(A, D), while the file has content C instead of A at this time This patch detects the above case and tell the user to rerun the test if they want to apply test changes.

patch: rewrite reversehunks (issue5337) The old reversehunks code accesses "crecord.uihunk._hunk", which is the raw recordhunk without crecord selection information, therefore "revert -i" cannot revert individual lines, aka. issue5337. The patch rewrites related logic to return the right reverse hunk for revert. Namely, 1. "fromline" and "toline" are correctly swapped [1] 2. crecord.uihunk generates a correct reverse hunk [2] Besides, reversehunks(hunks) will no longer modify its input "hunks", which is more expected. [1]: To explain why "fromline" and "toline" need to be swapped, take the following example: $ cat > a <<EOF > 1 > 2 > 3 > 4 > EOF $ cat > b <<EOF > 2 > 3 > 5 > EOF $ diff a b 1d0 <---- "1" is "fromline" and "0" is "toline" < 1 and they are swapped if diff from the reversed direction 4c3 | < 4 | --- | > 5 | | $ diff b a | 0a1 <---------+ > 1 3c4 <---- also "4c3" gets swapped to "3c4" < 5 --- > 4 [2]: This is a bit tricky. For example, given a file which is empty in working parent but has 3 lines in working copy, and the user selection: select hunk to discard [x] +1 [ ] +2 [x] +3 The user intent is to drop "1" and "3" in working copy but keep "2", so the reverse patch would be something like: -1 2 (2 is a "context line") -3 We cannot just take all selected lines and swap "-" and "+", which will be: -1 -3 That patch won't apply because of "2". So the correct way is to insert "2" as a "context line" by inserting it first then deleting it: -2 +2 Therefore, the correct revert patch is: -1 -2 +2 -3 It could be reordered to look more like a common diff hunk: -1 -2 -3 +2 Note: It's possible to return multiple hunks so there won't be lines like "-2", "+2". But the current implementation is much simpler. For deletions, like the working parent has "1\n2\n3\n" and it was changed to empty in working copy: select hunk to discard [x] -1 [ ] -2 [x] -3 The user intent is to drop the deletion of 1 and 3 (in other words, keep those lines), but still delete "2". The reverse patch is meant to be applied to working copy which is empty. So the patch would be: +1 +3 That is to say, there is no need to special handle the unselected "2" like the above insertion case.

profiling: cope with configwith default value handling changes Changeset 6ff6eb33f353 change 'configwith' behavior so that the default value is run through the conversion function. In parallel a new user of 'configwith' got introduced unaware of this coming behavior change. This broke profiling. We resolve the situation by having the new conversion function cope with a default value already using the right type.

py3: catch StopIteration from next() in generatorset IIUC, letting the StopIteration through would not cause any bugs, but not doing it makes the test-py3-commands.t pass. I have also diligently gone through all uses of next() in our code base. They either: * are not called from a generator * pass a default value to next() * catch StopException * work on infinite iterators * request a fixed number of items that matches the generated number * are about batching in wireproto which I didn't quite follow I'd appreciate if Augie or someone else could take a look at the wireproto batching and convince themselves that the next(batchable) calls there will not raise a StopIteration.

tests: adjust quoting to keep Windows happy with recent $PYTHON change I tried adding quotes to the $PYTHON variable, and also tried converting the path from the current 'c:/Python/python.exe' form to '/c/python/python.exe', but neither worked. I'm not sure why one of these needs '\"' around the variable and the other doesn't.

bundle2: don't use debug message "no-transaction" with transaction

py3: use pycompat.bytestr() in place of str()

py3: use r'' to access values from kwargs where keys are str These are the cases where either args is again passed as keyword argument or 1 or 2 elements are accessed. So it's better to add an r'' to prevent it converting to bytes rather than doing the conversion of args.

py3: convert keys of kwargs in template keywords functions to bytes This patch converts the args argument keys' to bytes wherever necessary as there are some places where either args is not used or using r'' is better or args is again passed as keyword arguments.

py3: make sure the commands name are bytes in test-devel-warnings.t

py3: replace str with bytes in isinstance() We were using str because on Python 2, str were bytes but now we have to use bytes. Otherwise the if conditions fails and we have weird results from commands on Python 3.

py3: catch binascii.Error raised from binascii.unhexlify Before Python 3, binsacii.unhexlify used to raise TypeError, now it raises binascii.Error.

shelve: allow unlimited shelved changes per name Previously, there is a 100 changes limit per name (bookmark or named branch). And the user will get "too many shelved changes named %s" when they are trying to shelve the 101th change. I hit that error message today. This limit was introduced by the shelve extension since the beginning. The function generating the names was called "gennames", under "getshelvename". There is another "gennames" under "backupfilename": def backupfilename(self): def gennames(base): yield base base, ext = base.rsplit('.', 1) for i in itertools.count(1): yield '%s-%d.%s' % (base, i, ext) "itertools.count" is an endless counter. Since the other "gennames" generates unlimited number of names, and the changeset introducing the limit (49d4919d21) does not say why the limit is useful. It seems safe to just remove the limit. The format "%02d" was kept intentionally so existing shelved changes won't break.

config: use the new '_unset' value for 'configsuboptions' This should let configsuboptions delegate all special processing of the default config value to the main 'config' method.

config: use the 'config' method in 'configsuboptions' There was unnecessary code duplication. It was getting in the way of the unification of the default value logic.

config: use the new '_unset' value for 'configpath' This should let 'configpath' delegate all special processing of the default config value to the main 'config' method.

config: use the new '_unset' value for 'configdate' This should let 'configdate' delegate all special processing of the default config value to the main 'config' method. The default value for date (None) is still enforced in this method if no other default were passed.

config: use the new '_unset' value for 'configlist' This should let 'configlist' delegate all special processing of the default config value to the main 'config' method. The default config value ([]) is still handled in this method.

config: use the new '_unset' value for 'configbytes' This should let 'configbytes' delegates all special processing of the default config value to the main 'config' method.

config: use the new '_unset' value for 'configint' This should let 'configint' delegates all special processing of the default config value to the main 'config' method.

config: use the new '_unset' value for 'configwith' This should let 'configwith' delegate all special processing of the default config value to the main 'config' method. This changeset introduce a small change in behavior since the default value is run through the 'convert' function. This does not seems harmful and no actual test break. This small change make the code simpler so I'm keeping it.

config: use the new '_unset' value for 'configbool' This should let 'configbool' delegate all special processing of the default config value to the main 'config' method. The default value for bool (False) is still enforced in this method if no other default were passed.

config: explicitly track the use of the standard default value We introduce a small object used to detect that no specific default value has been passed to 'ui.config'. We need this explicit special value since "None" is a valid and common default value. The end goal here is to make progress on a centralised and explicit declaration of the available config option. A first good usecase for this are "default" value. Before starting looking further down this alley we needs to rework the handling of default value in the 'ui' object to have all configxyz methods going through the same logic. This is the first changeset on this trek.

clonebundle: update hook arguments (BC) By calling applybundle() with 'clonebundles' and the url instead of calling processbundle(), the hooks will get different arguments: HG_SOURCE will be 'clonebundles' instead of 'bundle2' and HG_URL will be the url instead of 'bundle2'. This is consistent with the bundle1 behavior and seems like a bug fix, but I'm marking it BC anyway.

commands: move checkconflict to bookmarks module Again, commands.bookmark is getting too large. checkconflict already has a lot of state and putting it in the bmstore makes more sense than having it as a closure. This also allows extensions a place to override this behavior. While we're here, add a documentation string because, well, we should be documenting more of our methods.

commands: move checkformat to bookmarks module commands.bookmark has grown quite large with two closures already. Let's split this up (and in the process allow extensions to override the default behavior).

tests: tell pip not to check for a newer version pip will check to see if it's the latest version, and complain if it isn't. The --no-index flag implies the --disable-pip-version-check flag, and makes the warning (and any associated network activity) go away.

changeset_templater: backport parts map of [templates] section from formatter

formatter: add support for parts map of [templates] section Unlike a mapfile whose template is looked up by spec -> mapfile -> topic, [templates] section is global. We use :sub-section syntax to define parts per template.

changeset_templater: backport separator template from formatter As commented, this should be used with docheader and docfooter, not with header nor footer. That's one reason why no props are passed to templater when rendering a separator. (See map-cmdline.changelog to understand what the "header" is.)

formatter: add support for separator template This seems useful for writing JSON template.

formatter: add support for docheader and docfooter templates templatepartsmap() is a minimal copy of changeset_templater.__init__(). I tried to factor out a common function, but it was unnecessarily complicated.

formatter: extract helper function to render template

changeset_templater: do not enable verbosity postfix for [templates] section Since this postfix hack exists only for backward compatibility, we don't need it for new [templates] section. This isn't a BC as templates defined in [templates] section weren't loaded until recently.

changeset_templater: simplify handling of verbosity postfix

merge with stable

tests: don't touch the network when using virtualenv

tests: removed ReportedTest exception The only call site called addFailure before raising, which is exactly what the failure exception handler does. So this complexity is not needed. We have test coverage of this "server failed to start" scenario and nothing appeared to change.

tests: remove support for warned tests The previous changeset removed the last caller of addWarn(). So, we rip out that method and all the code related to tracking warned tests in the results system. There was even a comment saying we may want to fold warned tests into the "failed" state, which is what the previous changeset did.

contrib: add check-code rule to enforce non-use of `python` in tests

cleanup: use $PYTHON to run python in many more tests Spotted one of these, then wrote a check-code rule that caught them all. It will be the next change.

tests: enforce use of $PYTHON in tests

tests: use $PYTHON in #! so we always use the right Python

tests: sed away python #! in test-run-tests.t to avoid some upcoming insanity

tests: remove #! from primes.py in test-highlight.t It's about to be a source of trouble, but removing it changes a ton of test lines, so doing this change as a standalone commit.

keyword: use context manager for rollback locking
