mercurial: Changelog

changegroup: cg3 has two empty groups *after* manifests changegroup.getchunks() determines the end of the stream by looking for an empty chunk group (two consecutive empty chunks). It ignores empty groups in the first two groups. Changegroup 3 introduced an empty chunk between the manifests and the files, which confuses getchunks(). Since it comes after the first two, getchunks() will stop there. Fix by rewriting getchunks so it first counts two groups (empty or not) and then keeps antostarts counting empty groups. With this counting, changegroup 1 and 2 have exactly one empty group after the first two groups, while changegroup 3 has two (one for directories and one for files). It's a little hard to test this at this point, but I have verified that this patch fixes narrowhg (which was broken before this patch). Also, future patches will fix "hg strip" with treemanifests, and once that's done, getchunks() will be tested through tests of "hg strip".

mq: check for reserved patch name with qimport -r (issue5033) Fix regression from 143b52fce68e. Catching aborts might not be pretty but it works and is a small change.

mq: refactor makepatchname into class method

repoview: fix corrupted hiddencache crash Mercurial (issue5042) Before this patch if the hiddencache existed but was empty, it would crash mercurial. This patch adds exception handling when reading the hiddencache to avoid the issue. When encountering a corrupted cache file we print a devel warning. There would be no point in issuing a normal warning as the user wouldn't be able to do anything about the situation. The warning looks like: devel-warn: corrupted hidden cache, removing it at: /path/to/repoview.py

repoview: add missing newline character in debug prints

commandserver: drop tell() and seek() from channels (issue5049) These operations are obviously invalid for file-like channels because they will read or write protocol headers. This patch works around the issue that "hg archive" generates a corrupted zip file on Windows commandserver because of unusable tell() implementation. But the problem still occurs without using a commandserver. $ hg archive -R not-small-repo -t zip - | cat > invalid.zip So, this patch cannot fix the issue5049 completely.

crecord: edit during hg crecord should preserve cursor position (issue5041) This patch adds a variable to keep track of what hunk was selected before the edit. We use that variable to select the hunk or its replacement after the edit.

templates: use canvaswidth instead of fixed width for canvas (issue2683) Before this patch, template files for "graph" web page use fixed width size "480" for canvas element. This causes pruned lanes and invisible vertexes, if there are 16 or more vertical lanes at once. In such case, part of graph in right side area over 480 is invisible, even though corresponded summary text blocks are visible correctly. This limitation isn't reasonable for workflow using many branches at once (e.g. "one branch per issue" workflow). There were changes below related to width of canvas: - 7359cb753a54 (templates: widen the graph canvas (issue2683)), released as a part of Mercurial 1.8.2 According to the description, this assumed that 15 parallel branches was enough for ordinary workflow, and bumped width of canvas up from 224 to 480. - d490edc71146 (hgweb: make graph data suitable for template usage), released as a part of Mercurial 2.3 This introduced "canvaswidth" template keyword as a part of refactoring around graph rendering. But 'width="480"' of canvas element in template files wasn't replaced by 'width="{canvaswidth}"' in it (or subsequent one). This patch uses dynamic value "{canvaswidth}" instead of fixed width size "480" for canvas element. This is posted for "stable", because: - this is re-fixing issue2683 - this is simple enough for stable - using "{canvaswidth}" doesn't require any additional cost Calculation of canvaswidth is already implied as a part of "graph" web command.
