Before this patch, "rebase.concludenode()" uses "dirstate.invalidate()" as a kind of "restore .hg/dirstate to the original status" during a failure. But it just discards changes in memory, and doesn't actually restore ".hg/dirstate". Then, it can't work as expected, if "dirstate.write()" is executed while processing. This patch uses "dirstateguard" instead of "dirstate.invalidate()" to restore ".hg/dirstate" during a failure even if "dirstate.write()" is executed before a failure. This patch also removes "beginparentchage()" and "endparentchange()", because "dirstateguard" makes them useless. This is a part of preparations to fix the issue that the recent (in memory) dirstate isn't visible to external processes (e.g. "precommit" hook). After this patch, the changed dirstate becomes visible to external "precommit" hooks during "hg rebase" in "test-largefiles-misc.t", because "dirstateguard()" writes it out. But this content isn't yet correct, because: - "normal3" should be marked as "A"(dded) at committing It is newly added in the changeset being rebased. - but it is marked as "M"(odified) The result of "repo.setparents()" after "dirstateguard()" isn't yet written out before "precommit". So, merging is still in progress for "hg status" in it. This causes marking the file newly added on "other" branch as "A". This will be fixed by subsequent patch.

To fix the issue that the recent (in memory) dirstate isn't visible to external process (e.g. "precommit" hook), a subsequent patch makes "localrepository.commit()" invoke "dirstate.write()" in it. This change will make "beginparentchange()" and "endparentchange()" on dirstate in "cmdutil.tryimportone()" meaningless, because: - "dirstate.write()" writes changed data into ".hg/dirstate", but - aborting between "beginparentchange()" and "endparentchange()" doesn't cause any restoring ".hg/dirstate" it just discards changes in memory. This patch uses "dirstateguard" instead of "beginparentchange()" and "endparentchange()" in "cmdutil.tryimportone()" to restore ".hg/dirstate" during a failure even if "dirstate.write()" is executed before a failure. This patch uses "lockmod.release(dsguard)" instead of "dsguard.release()", because processing may be aborted before assignment to "dsguard" , and the "if dsguard" examination for safety is redundant.

Before this patch, releasing the store lock implies the actions below, when the transaction is aborted: 1. "commithook()" scheduled in "localrepository.commit()" is invoked 2. "changectx.__init__()" is invoked via "self.__contains__()" 3. specified ID is examined against "repo.dirstate.p1()" 4. validation function is invoked in "dirstate.p1()" In subsequent patches, "dirstate.invalidate()" invocations for discarding changes are replaced with "dirstateguard", but discarding changes by "dirstateguard" is executed after releasing the store lock: resources are acquired in "wlock => dirstateguard => store lock" order, and are released in reverse order. This may cause that "dirstate.p1()" still refers to the changeset to be rolled-back at (4) above: pushing multiple patches by "hg qpush" is a typical case. When releasing the store lock, such changesets are: - not contained in "repo.changelog", if it is reloaded from ".hg/00changelog.i", as that file was already truncated by "transaction.abort()" - still contained in it, otherwise (this "dirty read" problem is discussed in "Transaction Plan" http://mercurial.selenic.com/wiki/TransactionPlan) Validation function shows "unknown working parent" warning in the former case, but reloading "repo.changelog" depends on the timestamp of ".hg/00changelog.i". This causes occasional test failures. In the case of scheduled "commithook()", it just wants to examine whether "node ID" of committed changeset is still valid or not. Other examinations implied in "changectx.__init__()" are meaningless. To avoid showing the "unknown working parent" warning irregularly, this patch uses "changelog.hasnode()" instead of "node in self" to examine existence of committed changeset.

Before this patch, after "dirstate.write()" execution, there was no way to restore dirstate to the original status before "dirstate.write()". In some code paths, "dirstate.invalidate()" is used as a kind of "restore .hg/dirstate to the original status", but it just avoids writing changes in memory out, and doesn't actually restore the ".hg/dirstate" file. To fix the issue that the recent (in memory) dirstate isn't visible to external processes (e.g. "precommit" hooks), "dirstate.write()" should be invoked before invocation of external processes. But at the same time, ".hg/dirstate" should be restored to its content before "dirstate.write()" during an unexpected failure in some cases. This patch adds the class "dirstateguard" to easily restore ".hg/dirstate" during unexpected failures. Typical usecase of it is: # (1) build dirstate up .... # (2) write dirstate out, and backup ".hg/dirstate" dsguard = dirstateguard(repo, 'scopename') try: # (3) execute somethig to do: # this may imply making some additional changes on dirstate .... # (4) unlink backed-up dirstate file at the end of dsguard scope dsguard.close() finally: # (5) if execution is aborted before "dsguard.close()", # ".hg/dirstate" is restored from the backup dsguard.release() For this kind of issue, an "extending transaction" approach (in https://titanpad.com/mercurial32-sprint) seems to not be suitable, because: - transaction nesting occurs in some cases (e.g. "shelve => rebase"), and - "dirstate" may be already modified since the beginning of OUTER transaction scope, then - dirstate should be backed up into the file other than "dirstate.journal" at the beginning of INNER transaction scope, but - such alternative backup files are useless for transaction itself, and increases complication of its implementation "transaction" and "dirstateguard" differ from each other also in "what it should do for .hg/dirstate" in cases other than success. ============== ======= ======== ============= type success fail "hg rollback" ============== ======= ======== ============= transaction keep keep restore dirstateguard keep restore (not implied) ============== ======= ======== ============= Some collaboration between transaction and dirstate will probably be introduced in the future. But this layer is needed in all cases.

Previously this function accepted two optional parameters that were unused by any callers and complicated the function. Today, the terms 'active' and 'current' are interchangeably used throughout the codebase in reference to the active bookmark (the bookmark that will be updated with the next commit). This leads to confusion among developers and users. This patch is part of a series to standardize the usage to 'active' throughout the mercurial codebase and user interface.

The json code was changing the order of the time tuple for unclear reasons. We now use the same order as everywhere else.

We are about to record more complex time-related data, which will require repeated changes of every loop touching times data. That will also extend such lines to a point where things become too long. Instead, we iterate on each entry and expand values in the loops. We keep intermediate variables in most cases to preserve readability. The loop producing json data does a strange inversion for no obvious reason. We preserved that for now and will fix it in another changeset.

We are about to add more timing related information to each entry. Having a single place where the json entry is created is going to be much simpler.

We already have a _repo property on the packer, and we only access the changelog and manifest revlog in one place, so it's just as easy to get them from self._repo.

Future work will allow us to use docker to build debs. Right now this doesn't install any config files. I plan to do that as a followup, but getting something basic and working checked in seems like more of a priority than getting everything done in one big step. This also does not create a source deb yet. I haven't looked into that process. Note that this declares incompatibility with the `mercurial-common` package. It's typical for debian packages to be split between architecture-independent bits and native bits, meaning the python bits downstream live in mercurial-common and the c extension bits live in mercurial. We don't do that because we want to (ideally) give users a single deb file to install.

This allows me to build rpm packages using boot2docker on my Mac. It's probably a very fragile hack, but it seems to work well enough for now that I felt it was worth sharing.

I'm about to start interacting with docker for Debian packaging too, so it's time to centralize this so that any bugfixes I figure out apply to both codepaths.

db7463aa080f fixed the issue of double escapes, but it made the following template fail with syntax error because of <\">. Strictly speaking, <\"> appears to be invalid in non-string part, but we are likely to escape <"> if surrounded by quotes, and we are used to write such templates by trial and error. [templates] sl = "{tags % \"{ifeq(tag,'tip','',label('log.tag', ' {tag}'))}\"}" So, for backward compatibility between 2.8.1 and 3.4, a single backslash before quotation mark is stripped only in quoted template. We don't care for <\"> in string literal in quoted template, which never worked as expected before. template result --------- ------------------------ {\"\"} parse error "{""}" {""} -> <> "{\"\"}" {""} -> <> {"\""} {"\""} -> <"> '{"\""}' {"\""} -> <"> "{"\""}" parse error (don't care)

This methods is needed internally by utilities like __repr__. I do not see any harm in having it declared. Any actual attempt to use it to call a test would crash, but at least random debug print in the test runner will no longer crash. Another approach would have been to redefine the __repr__ function, but I think it a good thing to have some respect for the base class API.

If histedit failed after all the rules were complete (for instance, if there was an exception in the cleanup phase), you couldn't --continue because it was unable to pop a rule. Let's just skip the rule execution phase of --continue if there are no more rules.
