test-merge-tools: create repo directory to free $TESTTMP for temporary files

tests: update py3 test since json fields are now sorted The fields have been sorted since 814151cd8c4a (logcmdutil: rewrite jsonchangeset printer to be backed by jsonformatter, 2018-04-13), and the test case has thus been failing since that commit. Differential Revision: https://phab.mercurial-scm.org/D3570

tests: test-parseindex.t works just fine with chg In 538e850ae737 I annotated tests that failed with chg with "#require no-chg", but did not investigate why the tests were failing. This test was failing for unrelated reasons (I forgot to rebuild hg) and so should not be marked as no-chg. Test Plan: make local pushd contrib/chg make clean; make popd cd tests for f in '' --with-chg=../contrib/chg/chg; do ./run-tests.py --local $f test-parseindex.t done Differential Revision: https://phab.mercurial-scm.org/D3571

dispatch: mask negative exit code recorded in blackbox log That's what we do for the exit code delivered to the environment.

dispatch: fix exit code of unhandled exception recorded in blackbox log Spotted by Martin von Zweigbergk. We might want to change the exit code to -1 (i.e. 255) because 1 means non-abort error in hg, but that's another issue.

tests: mark tests that fail when using chg as #require no-chg As far as I can tell, most of these failures are due to using $HGPORT, which it seems chg might be using itself? I don't know enough to debug these failures to fix them properly. Differential Revision: https://phab.mercurial-scm.org/D3562

export: add -B option to select a bookmark Just like `hg email -B`, `hg strip -B`, supports -B in export to select a list of changesets reachable from a bookmark.

packaging: move most packaging targets to own Makefile Since we're putting everything packaging under one roof, let's define the make targets related to packaging there as well. I didn't move the "osx" target because it is non-trivial. Some targets did change slightly as part of the move. But it was mostly around path normalization. Differential Revision: https://phab.mercurial-scm.org/D3552

packaging: move most of contrib/docker to contrib/packaging/docker contrib/ is kind of a dumping ground for all kinds of random things. Many of the files in contrib/ are related to packaging. But sorting out how everything is related is a lot of effort since it is all mixed together. This commit starts the process of refactoring everything related to packaging so it all lives under one roof. Most content from contrib/docker is simply moved to contrib/packaging/docker and all references are updated. Differential Revision: https://phab.mercurial-scm.org/D3541

setup: reformat options argument This makes things a bit more easier to manage IMO. Differential Revision: https://phab.mercurial-scm.org/D3540

contrib: remove fixpax.py This was used as part of bdist_mpkg. And we stopped using bdist_mpkg after db5084d27df5. Differential Revision: https://phab.mercurial-scm.org/D3539

push: continue without locking on lock failure other than EEXIST (issue5882) This code was added by 3f5e75c22585 "push: make locking of source optional (issue3684)", but EACCES isn't the only error that could be triggered by filesystem permission. I think catching LockUnavailable is more appropriate than testing errno value by caller.

revlog: handle errors from index_node() in nt_insert() and index_slice_del() Same idea as in a9d9802d577e (revlog: don't say "not found" on internal error, 2018-05-04). Differential Revision: https://phab.mercurial-scm.org/D3558

help: add new deprecated topic Add a deprecated topic which lists most of the commands and options that are not recommended anymore.

phabricator: split auth.url into the standard auth.schemes and auth.prefix It seems better to reuse the existing function to find the proper [auth] block, even if not all of the possible settings may be of interest. The other callers of readauthforuri() make a trip through the password database to fetch the user from the URI. But in the little experimenting I did here, the username always came back as None. Since readauthforuri() wants it to make sure that user@prefix matches user@url, it seems that parsing the URL and pulling out the user component should be equivalent.

phabricator: migrate [phabricator.auth] to [auth] This resurrects the warning mechanism removed in 20a4543e9a2b. I'm not worried about the copy/paste of the code for a brief transitional period.

dispatch: unify handling of None returned by a command function A command function may return None in place of 0 just for convenience, but dispatch() doesn't need to inherit that property. This patch makes it be friendly to callers.

dispatch: minor code refactor This hopefully makes things slightly easier to read. Differential Revision: https://phab.mercurial-scm.org/D3537

hgweb: drop unused argument 'tmpl' from webutil.compare()

hgweb: convert {comparison} to a mappinggenerator with named template No bare generator.

hgweb: rename 'context' argument of webutil.compare() to avoid name conflicts The meaning of 'context' depends on context. Here it is the number of the context lines in unified diff.

hgweb: convert comparison {lines} to a mappinggenerator with named template Bare generator can't be restarted.

hgweb: move getblock() closure out of compare() (Please use 'hg diff -w' to get readable diff from this patch.)

hgweb: move compline() closure out of compare()

hgweb: convert {diff} to a mappinggenerator with named template No more bare generator. Fortunately, this one is associated with a single template, so it can be a mappinggenerator.

hgweb: use template context to render {lines} of {diff} This is a preferred way to process nested templates.

hgweb: wrap {lines} of {diff} with mappedgenerator This can't be a mappinggenerator as it switches the templates conditionally.

hgweb: move prettyprintlines() closure out of diffs() This will be wrapped with mappedgenerator.

remotenames: enable the storage config option if extension is enabled Before this patch, the config option to store remotenames was set to False by default and remotenames extension does not set it True. So if you enable remotenames extension without setting 'experimental.remotenames=True', you won't get the remotenames. This patch makes remotenames enable the config option if then extension is enabled which makes sense. Differential Revision: https://phab.mercurial-scm.org/D3520

tests: clone the repo over ssh in tests/test-logexchange.t Cloning a local repo in tests, and normally too does not perform the actual clone, rather it copies the file contents. This makes remotenames information not being transferred. Let's clone over ssh so that we can test remotenames correctly. Differential Revision: https://phab.mercurial-scm.org/D3519

remotenames: check the remotepath with url containing user information too Current logic to match a remotepatch to a user defined path first removes the authentication information from the url and then tries to match it. However this is not true every time. If we clone a repo using ssh, the default path contains the user information too. Differential Revision: https://phab.mercurial-scm.org/D3518

bdiff: fix yet more fallout from xdiff long/int64 conversion (issue5885) "l" in Py_BuildValue's format string means long, so passing int64_t instead results in fireworks on 32bit architectures. Differential Revision: https://phab.mercurial-scm.org/D3538

revlog: handle error from node lookup I missed this in D3499. Thanks to Yuya for spotting it. Differential Revision: https://phab.mercurial-scm.org/D3530

debugextensions: process extensions loaded from the local repository too

phabricator: drop support for the deprecated `phabricator.token` config

help: load module doc of disabled extension in extensions.disabledcmd() This helps rewriting _finddisablecmd() to not load the module.

extensions: extract closure that looks for commands from disabled module I'll rewrite this function to not load disabled extensions.

extensions: drop dead code trying to exclude deprecated disabled commands Here 'ext' is a tuple, which means ext.__doc__ describes about the Python tuple type. Fixing this would break 'hg help glog', which currently shows some nice explanation, so this patch just removes the dead code. $ hg help glog 'glog' is provided by the following extension: graphlog command to view revision graphs from a shell (DEPRECATED) (use 'hg help extensions' for information on enabling extensions)

util: drop remainder of dateutil/procutil aliases (API)

shortest: move revnum-disambiguation out of revlog I want to be able to change how we disambiguate and I think having revlog.shortest() worry only about finding a prefix that's unambiguous among nodeids makes more sense. This slows down `hg log -T '{shortest(node,1)}\n'` from 4.0s to 4.1s. Differential Revision: https://phab.mercurial-scm.org/D3502

shortest: remove unnecessary check for revnum in isvalid() We now always disambiguating against revnums after we've found an otherwise valid prefix, so we can safely remove the early isrev() check in isvalid(). Differential Revision: https://phab.mercurial-scm.org/D3501

shortest: make pure code also disambigute against revnums at end This makes the pure code more similar to the native code in that it first finds a prefix that's unambiguous among nodeids and then adds hex digits until it no longer looks like a revnum. It will allow us to even better separate the disambiguation with revnums in a later patch. With this patch `hg log -r 0::50 -T '{shortest(node,1)}'` with no native code goes from 25s to 43s. It wasn't exactly usable to begin with, so I don't feel too bad about it. Differential Revision: https://phab.mercurial-scm.org/D3500

revlog: use node tree (native code) for shortest() calculation I want to rewrite revlog.shortest() to disambiguate only among hex nodeids and then disambiguate the result with revnums at a higher level (in scmutil). However, that would slow down `hg log -T '{shortest(node,1)}\n'` from 5.0s to 6.8s, which I wasn't sure would be acceptable. So this patch makes revlog.shortest() use the node tree for finding the length of the shortest prefix that's unambiguous among nodeids. Once that has been found, it makes it longer until it is also not ambiguous with a revnum. This speeds up `hg log -T '{shortest(node,1)}\n'` from 5.0s to 4.0s.

shelve: reduce scope of merge tool config override The config override seems to have a much greater scope than it needed to. I *think* it's only relevant in the while merging files. The rebase step also cares about the merge tool, but we seem to be explicitly passing it to rebase (around line 755). Differential Revision: https://phab.mercurial-scm.org/D3517

hgweb: remove unused argument 'tmpl' from listfilediffs()

hgweb: use template context to render {files} of changelist entries This is a preferred way to process nested templates.

hgweb: wrap {files} of changelist entries with mappedgenerator This also switches the associated templates conditionally, which can't be a mappinggenerator.

hgweb: use template context to render {files} of changesetentry() This is a preferred way to process nested templates.

hgweb: wrap {files} of changesetentry() with mappedgenerator This can't be easily adapted to mappinggenerator because the associated templates are switched per item.

hgweb: extract generator of {files} from changesetentry() This will be wrapped with mappedgenerator.

templatefilters: document the json filter I don't know the exact reason why it was undocumented, but that would be because unicode is difficult for humans. Since the json filter can now get localstr back to UTF-8 as long as it is unprocessed (i.e. {desc|json} works, but {desc|firstline|json} doesn't), it seems good enough to advertise the json filter.

encoding: introduce tagging type for non-lossy non-ASCII string This fixes the weird behavior of toutf8b(), which would convert a local string back to UTF-8 *only if* it was lossy in the system encoding. Before b7b26e54e37a "encoding: avoid localstr when a string can be encoded losslessly (issue2763)", all local strings were wrapped by the localstr class. I think this would justify the round-trip behavior of toutf8b(). ASCII strings are special-cased, so the cost of wrapping with safelocalstr is negligible. (with mercurial repo) $ export HGRCPATH=/dev/null HGPLAIN= HGENCODING=latin-1 $ hg log --time --config experimental.evolution=all > /dev/null (original) time: real 11.340 secs (user 11.290+0.000 sys 0.060+0.000) time: real 11.390 secs (user 11.300+0.000 sys 0.080+0.000) time: real 11.430 secs (user 11.360+0.000 sys 0.070+0.000) (this patch) time: real 11.200 secs (user 11.100+0.000 sys 0.100+0.000) time: real 11.370 secs (user 11.300+0.000 sys 0.070+0.000) time: real 11.190 secs (user 11.130+0.000 sys 0.060+0.000)

encoding: fix toutf8b() to resurrect lossy characters even if "\xed" in it If 's' is a localstr, 's._utf8' must be returned to get the original UTF-8 sequence back. Because of this, it was totally wrong to test if '"\xed" not in s', which should be either '"\xed" not in s._utf8' or just omitted. This patch moves the localstr handling to top as the validity of 's._utf8' should be pre-checked by encoding.tolocal().

sshserver: redirect stdin/stdout early and use duplicated streams This is what we achieved with hook.redirect(True) plus ui.fout = ui.ferr. The hook.redirect() function can't be completely removed yet since hgweb still depends on it. I'm not sure if it is necessary for WSGI servers. CGI needs it, but does WSGI communicate over stdin/stdout channels?

sshserver: do setbinary() by caller (API) In most cases, stdio should be set to binary mode by the dispatcher, so the sshserver does not have to take care of that. The only exception was hg-ssh, which is fixed by this patch. .. api:: ``sshserver()`` no longer sets stdin and stdout to binary mode.

test-ssh: add some flush() to make output deterministic We shouldn't rely on buffering mode/state of file handles.

stringutil: flip the default of pprint() to bprefix=False If we use pprint() as a drop-in replacement for repr(), bprefix=False is more appropriate. Let's make it the default to remove bprefix=False noise.

stringutil: make pprint() forward uninteresting object to b'%r' We appear to start using pprint() as a replacement for repr(), so it's probably safer to support any Python objects instead of complaining about that.

This patch moves the warning about the hidden changeset to after the update has happened. It changes the verb tense accordingly (and drops the "a" that I think it sounds better without). Of course, this means that the commit isn't actually hidden anymore when the message is printed. I think that's fine. Differential Revision: https://phab.mercurial-scm.org/D3479
