_adjustlinkrev: reuse ancestors set during rename detection (issue4514) The new linkrev adjustement mechanism makes rename detection very slow, because each file rewalks the ancestor dag. To mitigate the issue in Mercurial 3.3, we introduce a simplistic way to share the ancestors computation for the linkrev validation phase. We can reuse the ancestors in that case because we do not care about sub-branching in the ancestors graph. The cached set will be use to check if the linkrev is valid in the search context. This is the vast majority of the ancestors usage during copies search since the uncached one will only be used when linkrev is invalid, which is hopefully rare.

filectx: move _adjustlinkrev to a method We are going to introduce some wider caching mechanisms during linkrev adjustment. As there is no specific reason to not be a method and some reasons to be a method, let's make it a method.

revset: raise RepoLookupError to make present() predicate continue the query Before this patch, "bookmark()", "named()" and "tag()" predicates raise "Abort", when the specified pattern doesn't match against existing ones. This prevents "present()" predicate from continuing the query, because it only catches "RepoLookupError". This patch raises "RepoLookupError" instead of "Abort", to make "present()" predicate continue the query, even if "bookmark()", "named()" or "tag()" in the sub-query of it are aborted. This patch doesn't contain raising "RepoLookupError" for "re:" pattern in "tag()", because "tag()" treats it differently from others. Actions of each predicates at failure of pattern matching can be summarized as below: predicate "literal:" "re:" ---------- ----------- ------------ bookmark abort abort named abort abort tag abort continue (*1) branch abort continue (*2) ---------- ----------- ------------ "tag()" may have to abort in the (*1) case for similarity, but this change may break backward compatibility of existing revset queries. It seems to have to be changed on "default" branch (with "BC" ?). On the other hand, (*2) seems to be reasonable, even though it breaks similarity, because "branch()" in this case doesn't check exact existence of branches, but does pick up revisions of which branch matches against the pattern. This patch also adds tests for "branch()" to clarify behavior around "present()" of similar predicates, even though this patch doesn't change "branch()".

templatekw: re-add showtags() to list tags keyword up in online help Changeset d69a7fc68ad5 removed "showtags()" definition for "tags" template keyword from "templatekw.py", because "namespaces" puts a helper function for it into template keyword map automatically. This works correctly from the point of view of templating functionality. But on the other hand, it removed "tags" template keyword from "hg help templates" unexpectedly, because online help text is built before "namespaces" puts a helper function for "tags" into template keyword map. This patch is a kind of backing d69a7fc68ad5 out, but this implements "showtags()" with newly introduced "shownames()" instead of originally used "showlist()".

largefiles: don't interfere with logging normal files The previous code was adding standin files to the matcher's file list when neither the standin file nor the original existed in the context. Somehow, this was confusing the logging code into behaving differently from when the extension wasn't loaded. It seems that this was an attempt to support naming a directory that only contains largefiles, as a test fails if the else clause is dropped entirely. Therefore, only append the "standin" if it is a directory. This was found by running the test suite with --config extensions.largefiles=. The first added test used to log an additional cset that wasn't logged normally. The only relation it had to file 'a' is that 'a' was the source of a move, but it isn't clear why having '.hglf/a' in the list causes this change: @@ -47,6 +47,11 @@ Make sure largefiles doesn't interfere with logging a regular file $ hg log a --config extensions.largefiles= + changeset: 3:2ca5ba701980 + user: test + date: Thu Jan 01 00:00:04 1970 +0000 + summary: d + changeset: 0:9161b9aeaf16 user: test date: Thu Jan 01 00:00:01 1970 +0000 The second added test used to complain about a file not being in the parent revision: @@ -1638,10 +1643,8 @@ Ensure that largefiles doesn't intefere with following a normal file $ hg --config extensions.largefiles= log -f d -T '{desc}' -G - @ c - | - o a - + abort: cannot follow file not in parent revision: ".hglf/d" + [255] $ hg log -f d/a -T '{desc}' -G @ c | Note that there is still something fishy with the largefiles code, because when using a glob pattern like this: $ hg log 'glob:sub/*' the pattern list would contain '.hglf/glob:sub/*'. None of the tests show this (this test lives in test-largefiles.t at 1349), it was just something that I noticed when the code was loaded up with print statements.

discovery: properly exclude locally known but filtered heads The conditional was a bit too narrow and produced buggy result when a node was present in both common and heads (because it pleased the discovery) and it was locally known but filtered. This resulted in buggy getbundle request and server side crash.
