changegroup: wrap some ** expansions in strkwargs

obsolete: reuse _fm1metapair for computing _fm1metapairsize It's evaluated at import time, so it seems silly to not reuse the constant name.

evolution: rename unstable to orphan Rename unstable to orphan in all external user-facing output. Only update user-facing output for the moment, variables names, templates keyword and potentially configuration would be done in later series. The renaming is done according to https://www.mercurial-scm.org/wiki/CEDVocabulary. Differential Revision: https://phab.mercurial-scm.org/D214

bundle2: load hookargs from bundleoperation into transaction when started one When a transaction is started, we must load the hookargs from the bundleoperation object to the transaction so that they can be used in the transaction. Also this patch makes sure no more hookargs are added to the bundleoperation object once the transaction starts. This is a part of porting fb extension bundle2hooks to core. Differential Revision: https://phab.mercurial-scm.org/D209

bundle2: add the capability to store hookargs on bundle operation object There are extensions like pushrebase, pushvars which run hooks on a server before taking the lock. Since the lock is not taken, transaction is not there, so the hookargs can't be stored on the transaction. Adding hooksargs to bundle operation object will help in running hooks before taking the lock. This is a part of moving fb's extension bundle2hooks to core.

rebase: use one dirstateguard for when using rebase.singletransaction This was previously landed as 2519994d25ca but backed out in b63351f6a2 because it broke hooks mid-rebase and caused conflict resolution data loss in the event of unexpected exceptions. This new version adds the behavior back but behind a config flag, since the performance improvement is notable in large repositories. The old commit message was: Recently we switched rebases to run the entire rebase inside a single transaction, which dramatically improved the speed of rebases in repos with large working copies. Let's also move the dirstate into a single dirstateguard to get the same benefits. This let's us avoid serializing the dirstate after each commit. In a large repo, rebasing 27 commits is sped up by about 20%. I believe the test changes are because us touching the dirstate gave the transaction something to actually rollback.

tests: invoke run-tests.py in test-hghave using $PYTHON (issue5697) Some platforms (notably pkgsrc on NetBSD) only provide versioned Python interpreters (eg `python2.7` exists, but `python` does not), which exposes this error. We want to be running run-tests.py with the python given in $PYTHON, since that might be `pypy` or `python3`.

rebase: move bookmarks with --keep (issue5682) This is a regression caused by 3b7cb3d17137. We have documented the behavior in rebase help: Rebase will destroy original commits unless you use "--keep". It will also move your bookmarks (even if you do). So let's restore the old behavior. It is done by changing `scmutil.cleanupnodes` to accept more information so a node could have different "movement destination" from "successors". It also helps simplifying the callsite as a side effect - the special bookmark movement logic in rebase is removed. Differential Revision: https://phab.mercurial-scm.org/D727

cleanupnodes: rename "mapping" to "replacements" The next patch will pass in overrides for bookmark moves, which is a mapping itself, so let's rename "mapping" to "replacements" to distinguish them better. Differential Revision: https://phab.mercurial-scm.org/D749

cleanupnodes: separate out bookmark destination calculation from actual update We will soon want to pass in overrides for bookmark movements and this will make that patch simpler. I also think this makes the code easier to follow regardless of the later patch. Differential Revision: https://phab.mercurial-scm.org/D748

ui: check for progress singleton when clearing progress bar (issue5684) A combination of wrapping `ui` and progress bars interrupted by exceptions can lead to the progress bar not being cleared when the exception error is printed. This results in corrupted-looking output like this: ``` updating [===============================> ] 1/2u nresolved conflicts (see hg resolve, then hg rebase --continue) ``` This is because in `ui._progclear`, we only check the local reference to the progress bar, not whether or not there is an instance of the singleton. When a progress bar is interrupted by an exception, the exception printing in `scmutil.callcatch` uses the original instance of the `ui` object, not the wrapped copy that has `_progbar` set. When consider whether or not to clear the progress bar, check for the existence of the singleton, rather than just whether or not we have a local reference to it.

hgwebdir: read 'web.template' untrusted The 'hgweb_mod.py' version of this read it untrusted. For consistency we align the two versions of this code.

ssh: fix flakey ssh errors on BSD systems This is a trivial backport of c037fd655b47 performed by augie@google.com, but the change is still really Durham's not mine, so I [augie] am leaving him as the author.

repair: preserve phase also when not using generaldelta (issue5678) It seems like we used to pick the oldest possible version of the changegroup to use for bundles created by the repair module (used e.g. by "hg strip" and for temporary bundles by "hg rebase"). I tried to preserve that behavior when I created the changegroup.safeversion() method in 3b2ac2115464 (changegroup: introduce safeversion(), 2016-01-19). However, we have recently chagned our minds and decided that these commands are only used locally and downgrades are unlikely. That decicion allowed us to start adding obsmarker and phase information to these bundles. However, as the bug report shows, it means we get different behavior e.g. when generaldelta is not enabled (because when it was enabled, it forced us to use bundle2). The commit that actually caused the reported bug was 8e3021fd1a44 (strip: include phases in bundle (BC), 2017-06-15). So, since we now depend on having more information in the bundles, let's make sure we instead pick the newest possible changegroup version. Differential Revision: https://phab.mercurial-scm.org/D715

tests: add test for issue5678 In addition to a test case for the direct problem described in the bug report, this also adds a test case showing how obsmarkers can also get lost when not using generaldelta. Differential Revision: https://phab.mercurial-scm.org/D714

mq: create non-lossy patches, also with custom global diff configuration Users with custom [diff] configuration most certainly didn't intend it to make mq lose changes. It could: * git is handled perfectly fine. * nobinary could make mq leave some files out from the patches. * noprefix could make mq itself (and probably also other tools) fail to apply patches without the usual a/b prefix. * ignorews, ignorewsamount, or ignoreblanklines could create patches with missing whitespace that could fail to apply correctly. Thus, when refreshing patches, use patch.difffeatureopts, optionally with git as before, but without the config options for whitespace and format changing that most likely will cause loss or problems. (patch.diffopts is just patch.difffeatureopts with all options enabled and can be replaced with that.)

debugssl: allow a URL to be specified without a local repository This was the original intent, but I bungled the logic. Otherwise if there is a certificate chain issue, the repository can't be cloned in order for there to be a repo object. I think I missed this case because I was inside of a Mercurial clone as I was originally developing and testing this.

record: fix revert -i for lines without newline (issue5651) This is a regression caused by 66117dae87f9. Code prior to 66117dae87f9 seems to miss the "\ No newline at end of file" line. Differential Revision: https://phab.mercurial-scm.org/D528

templatekw: choose {latesttag} by len(changes), not date (issue5659) As Augie reported in the bug, the current heuristic of choosing the best tag of a merge commit by taking the one with newest tag (in terms of tagging date) currently fails in the Mercurial repo itself. Copying the example from Yuya: $ hg glog -T '{node|short} {latesttag}+{latesttagdistance}\n' \ -r '4.2.3: & (merge() + parents(merge()) + tag())' o 02a745c20121 4.2.3+5 |\ | o 86aca74a063b 4.2.3+4 | |\ | | o e6d8ee3c9ec3 4.3-rc+109 | | | | | ~ o | a3ce07e2dde5 4.3.1+2 : | o | 3fee7f7d2da0 4.3.1+0 |/ o 98e990bb7330 4.2.3+3 |\ | ~ o 506d7e48fbe6 4.2.3+2 : o 943c91326b23 4.2.3+0 | ~ It seems to me like the best choice is the tag with the smallest number of changes since it (across all paths, not the longest single path). So that's what this patch does, even though it's costly. Best-of-5 timings for Yuya's command above shows a slowdown from 1.293s to 1.610s. We can optimize it later.

ui: restore behavior to ignore some I/O errors (issue5658) e9646ff34d55 and 1bfb9a63b98e refactored ui methods to no longer silently swallow some IOError instances. This is arguably the correct thing to do. However, it had the unfortunate side-effect of causing StdioError to bubble up to sensitive code like transaction aborts, leading to an uncaught exceptions and failures to e.g. roll back a transaction. This could occur when a remote HTTP or SSH client connection dropped. The new behavior is resulting in semi-frequent "abandonded transaction" errors on multiple high-volume repositories at Mozilla. This commit effectively reverts e9646ff34d55 and 1bfb9a63b98e to restore the old behavior. I agree with the principle that I/O errors shouldn't be ignored. That makes this change... unfortunate. However, our hands are tied for what to do on stable. I think the proper solution is for the ui's behavior to be configurable (possibly via a context manager). During critical sections like transaction rollback and abort, it should be possible to suppress errors. But this feature would not be appropriate on stable.
