rebase: do not raise an UnboundLocalError when called wrong (issue4106) When the base is not found, we should not raise a traceback about a not defined variable. This hides the real problem: the function rebasenode was (probably) called wrong. An AssertionError is raised to highlight that the caller of the function did something wrong. An alternative approach is to only assign None to the variable "base" and let the merge mechanism raise an abort message. This was the behaviour for this case before ad9db007656f. But the only known case for this problem is when an extension calls this function wrong. An AssertionError makes this clearer than an abort message. When a different case is detected, the behaviour can be improved then.

exchange: fix docs for pulloperation 'remote' is actually the remote, not the repo one is pulling into. This confused me quite a bit.

merge with stable

resolve: use "other" changeset from merge state (issue4163) We can use the "other" data from the recorded merge state instead of inferring what the other could be from working copy parent. This will allow resolve to fulfil its duty even when the second parent have been dropped. Most direct benefit is fixing a regression in backout.

merge: add "other" file node in the merge state file This data is mostly redundant with the "other" changeset node (+ other changeset file path). However, more data never hurt. The old format do not store it so this require some dancing to add and remove it on demand.

merge: infer the "other" changeset when falling back to v1 format When we have to fallback to the old version of the file, we infer the "other" from current working directory parent. The same way it is currently done in the resolve command. This is know to have shortcoming… but we cannot do better from the data contained in the old file format. This is actually the motivation to add this new file format.

merge: record the "other" node in merge state We need to record the merge we were merging with. This solve multiple bug with resolve when dropping the second parent after a merge. This happen a lot when doing special merge (overriding the ancestor). Backout, shelve, rebase, etc. can takes advantage of it. This changeset just add the information in the merge state. We'll use it in the resolve process in a later changeset.

merge: introduce new format for the state file This new format will allow us to address common bugs while doing special merge (graft, backout, rebase…) and record user choice during conflict resolution. The format is open so we can add more record for future usage. This file still store hexified version of node to help human willing to debug it by hand. The overhead or oversize are not expected be an issue. The old format is still used. It will be written to disk along side the newer format. And at parse time we detect if the data from old version of the mergestate are different from the one in the new version file. If its the same, both have most likely be written at the same time and you can trust the extra data from the new file. If it differs, the old file have been written by an older version of mercurial that did not knew about the new file. In that case we use the content of the old file.

merge: change the merge state serialisation to use a record based logic The format of the file is unchanged. But we are preparing a new file with a new format that would be record based. So we change all the read/write logic to handle a list of record until a very low level. This will allow simple plugging of the new format in the current code.

merge: move merge state file path into a constant We are about to change the format. Having the file path in a single place make it easier to update the filename for the new version.

revset: changed spanset __add__ implementation to work lazily $ time hg log -qr "first(0:tip or draft())" ... real 0m1.032s user 0m0.841s sys 0m0.179s $ time ./hg log -qr "first(0:tip or draft())" ... real 0m0.378s user 0m0.291s sys 0m0.085s

obsstore: add a __len__ method We can already use "for mark in store:" it make sense to allow "len(store)" too.

obsstore: `create` method return True if a marker is actually added The obsstore method now have a return value. This informs caller about the actual creation of a new markers. No new markers are created if it would have been a duplicate.

help: exclude deprecated extensions in the disabled part of 'help extensions'

test-help.t: add test for 'hg help extensions' This demonstrates the defect that deprecated extensions show up in the output. A followup patch will fix this defect.

coal: hgweb style adds extra blank line in file view (issue4136) Now hgweb style='coal' adds no extra blank in file view.

pull: close peer repo on completion (issue2491) (issue2797) When pulling changes from a compressed bundle Mercurial first uncompresses it to a temporary file in .hg directory. This file will not be deleted unless the bundlerepo (other) is explicitly closed. This is similar to cleanup that occurs after incoming.

hgweb: ensure isdirectory is None for repositories, replacing any True value Until now, repositories did not provide any value for isdirectory in rows produced for the index output, and thus isdirectory was generally evaluated as None for each index entry representing a repository. However, directories (visible when viewed with the descend and collapse settings enabled) did provide a value of True and this value appeared to persist in subsequent rows processed by the templater, causing isdirectory tests in templates to produce incorrect results for index entries appearing after directories. This patch asserts the None value for repositories, thus erasing any such persistent True values.

ui: suggest config --edit when no username is set

config: add example config file when -e called with no config

config: add initial implementation of --edit This launches the preferred editor on either: a) the first non-empty user rc file found b) the first user rc file in the search list

revert: extract actual revert in its own function With this small refactoring, the computation of the action to perform and the actual change to the disk happen in different function. This allows extension to wrap the later in case of need. The initial motivation is the `remotefilelog` extension that need to prefetch all the file content to be checked out.

config: move showconfig code and add config as primary alias Preparation for adding config --edit to launch an editor

purge: avoid duplicate output for --print (issue4092) Now "hg purge -p" commands avoids printiing duplication of filenames. Second patch is the test coverage of first patch which tells that '-p' does not depend on whether ui.verbose is configured or not,that means it is independent of '-v'.

revlog: introduce commonancestors method for getting all common ancestor heads

localrepo: commit: avoid calling expensive ancestor function when p1 is nullrev

ancestors: remove unnecessary handling of 'left' If one of the initial nodes also is an ancestor then that most be the only ancestor. There is no need for additional bookkeeping.

parsers: remove unreachable and invalid code in index_ancestors The function normally returns a list. Returning a single element instead of a list with one element would be weird.

cmdutil: implemented new lazy increasingwindows Now log can work in a lazy way and get results as soon as they are processed.

revset: added __nonzero__ method to lazyset Now it doesn't have to go through all the set and can return lazily as soon as it finds one element.

scmutil: changed revrange to return lazysets for new style revsets When there is an old style revset or both it will still return a baseset. This may be changed in later patches.

phases: make order of debug output 'removing unknown node' deterministic

comments: fix minor spelling issues found with spell checker

hooks: for python hooks, consistently use __name__ etc as name, not the repr There is no reason to expose unnecessary Python implementation details and memory locations, also not in debug mode. readablefunc was already creating a nice name - we move that functionality up and reuse it. We consider having a __call__ and being types.FunctionType sufficiently similar and unify these two to just using the existing check for __call__.

hooks: move logging of hook name to after we have found the hook We do not expect the finding process to take a significant amount of time - it is the execution time of the hook we care about.

rebase: show nice list instead of set repr for 'computed skipped revs' debug

rebase: fix 'rebase onto %d starting from %s' - show root instead of list repr The debug statement is already in a 'for root in roots' so it was probably the intention to show root instead of roots. Do that.

log: describe graph symbols in the help I wondered what 'x' meant and didn't find it described anywhere.

tests: backout a82de9dc4f77, debugstacktrace is now stable, drop workaround

util: debugstacktrace, flush before and after writing Close another stream (default stdout, which often is buffered) before writing to the primary stream (default stderr, which often is unbuffered). The primary stream is also flushed after writing (in case it is buffered). This fixes non-deterministic output order, especially on windows.

run-tests.py: work when --with-hg is set to system hg Previously we'd always assume that --with-hg is a script in a user directory, and would write out a 'python' symlink to the same location. That didn't work if --with-hg was set to a system installation of hg, e.g. /usr/bin/hg. Introduce a TMPBINDIR directory which is used to write out the python symlink.

revset: added cached generated list on generatorset This allows to iterate the generatorset more than once.

templater: shorten pure integers Originally, the addition of the 'shorten' template function in 9c6b86dd2ed2 would not consider pure integers for shortening. This patch considers two simple cases: when the integer starts with zero (which is parsed by Mercurial as a hash first) and when the integer is larger than the tip (obviously not a rev).

revset: fixed bug where log -f was taking too long to return
