sslutil: abort when ssl module is needed but not found It is apparently possible to compile Python without SSL support or leave it out when installing precompiled binaries. Mercurial on such Pythons would crash if the user tried to use https. Now it will be reported as "abort: Python SSL support not found" instead.

merge with stable

patch: correctly handle non-tabular Subject: line The line content of continued Subject: lines was yet joined via str.replace('\n\t', ' '), which does not handle continuation via spaces. So expan the regular expression instead to handle all allowed forms of mail header line continuation.

util: fix crash converting an invalid future date to string Post-2038 timestamps cannot be handled on 32-bit architectures. Clamp such dates to the maximum 32-bit timestamp.

styles: add new 'bisect' style that prints the bisection status The style is based on the 'default' style, but adds the bisection status of the changesets. Example output for a changeset in range: $ hg log --style bisect -r 15:16 changeset: 15:857b178a7cf3 bisect: bad parent: 13:b0a32c86eb31 parent: 10:429fcd26f52d user: test date: Thu Jan 01 00:00:15 1970 +0000 summary: merge 10,13 changeset: 16:609d82a7ebae bisect: bad (implicit) user: test date: Thu Jan 01 00:00:16 1970 +0000 summary: 16 $ hg log --quiet --style bisect 18:d42e18c7bc9b B 17:228c06deef46 B 16:609d82a7ebae B 15:857b178a7cf3 14:faa450606157 G 13:b0a32c86eb31 G 12:9f259202bbe7 G 11:82ca6f06eccd U 10:429fcd26f52d S 9:3c77083deb4a G 8:dab8161ac8fc 7:50c76098bbf2 I 6:a214d5d3811a I 5:385a529b6670 I 4:5c668c22234f I 3:0950834f0a9c I 2:051e12f87bf1 1:4ca5088da217 0:33b1f9bc8bc5 Signed-off-by: "Yann E.

templates: add 'bisect' keyword to return a cset's bisect status This new 'bisect' template expands to a cset's bisection status (good, bad and so on...). There is also a new 'shortbisect' filter that yields a single char representing the cset's bisection status. It uses the two recently-added hbisect.label() and .shortlabel() functions. Example output using the repository in test-bisect2.t, and some made-up state of the 'end at merge' test (with graphlog, it's so explicit): $ hg glog --template '{rev}:{node|short} {bisect}\n' \ -r 'bisect(range)|bisect(ignored)' o 17:228c06deef46: bad | o 16:609d82a7ebae: bad (implicit) | o 15:857b178a7cf3: bad |\ | o 13:b0a32c86eb31: good | | | o 12:9f259202bbe7: good (implicit) | | | o 11:82ca6f06eccd: good | | @ | 10:429fcd26f52d: untested |\ \ | o | 9:3c77083deb4a: skipped | |/ | o 8:dab8161ac8fc: good | | o | 6:a214d5d3811a: ignored |\ \ | o | 5:385a529b6670: ignored | | | o | | 4:5c668c22234f: ignored | | | o | | 3:0950834f0a9c: ignored |/ / o / 2:051e12f87bf1: ignored |/ And now the same with the short label: $ hg log --template '{bisect|shortbisect} {rev}:{node|short}\n' 18:d42e18c7bc9b B 17:228c06deef46 B 16:609d82a7ebae B 15:857b178a7cf3 14:faa450606157 G 13:b0a32c86eb31 G 12:9f259202bbe7 G 11:82ca6f06eccd U 10:429fcd26f52d S 9:3c77083deb4a G 8:dab8161ac8fc 7:50c76098bbf2 I 6:a214d5d3811a I 5:385a529b6670 I 4:5c668c22234f I 3:0950834f0a9c I 2:051e12f87bf1 1:4ca5088da217 0:33b1f9bc8bc5 Signed-off-by: "Yann E.

hbisect: add functions to return a label for a cset bisection status Add two new functions that return a string containing the bisection status of the node passed in parameter: - .label(node): return a multi-char string representing the status of node - .shortlabel(node): return a single-char string representing the status of node, usually the initial of the label bisection status .label() .shortlabel() ---------------------------------------------------------- good 'good' 'G' good (implicit) 'good (implicit)' 'G' bad 'bad' 'B' bad (implicit) 'bad (implicit)' 'B' skipped 'skip' 'S' untested 'untested' 'U' ignored 'ignored' 'I' (others) None None There is no point in returning 'range' or 'pruned', as these get covered by another, more meaningful status in the table above. In case the node is not being bisected, the functions return None to leave it up to the caller to decide what to print (nothing, an empty space, or whatever else suits). Signed-off-by: "Yann E.

hbisect: add two new revset descriptions: 'goods' and 'bads' This patch adds two new revset descriptions: - 'goods': the list of topologicaly-good csets: - if good csets are topologically before bad csets, yields '::good' - else, yields 'good::' - and conversely for 'bads' Signed-off-by: "Yann E.

http: handle push of bundles > 2 GB again (issue3017) It was very elegant that httpsendfile implemented __len__ like a string. It was however also dangerous because that protocol can't handle sizes bigger than 2 GB. Mercurial tried to work around that, but it turned out to be too easy to introduce new errors in this area. With this change __len__ is no longer implemented at all and the code will work the same way for short and long posts.

building: build inotify for sys.platform='linux*' If Python interpreter was built under Linux 3.x kernel, it reports sys.platform to be 'linux3' (it is fixed for Python 3, but not for 2.x). This cancels building inotify extension, which was built only for 'linux2' platform. Improved test checks if sys.platform begins with 'linux', and together with test for kernel version to be greater than 2.6 it seems to cover all known cases.

subrepo: try remapping subpaths using the "final" path Before, the right-hand side of a .hgsub entry was used, as is, to match the left-hand side of a subpaths entry. This turned out to be less useful than expected since a .hgsub file with src/foo = src/foo has little context to do remapping on. The new idea is therefore to prefix the parent repo path *before* the remapping takes place. If the parent repository path (as defined by _abssource) is http://example.net/parent then the remapping for the above .hgsub entry will be done on the expanded path: http://example.net/parent/src/foo If this expanded path is not changed by the remapping, then we remap src/foo alone. This is the old behavior where the right-hand side is remapped without context.

subrepo: refactor state function

mq.strip: allow -r option, optionally Other commands let -r to be used for revisions, so just for syntactic consistency, it's nice to have it for strip as well

revset.bisect: add 'ignored' set to the bisect keyword The 'ignored' changesets are outside the bisection range, but are changesets that may have an impact on the outcome of the bisection. For example, in case there's a merge between the good and bad csets, but the branch-point is out of the bisection range, and the issue originates from this branch, the branch will not be visited by bisect and bisect will find that the culprit cset is the merge. So, the 'ignored' set is equivalent to: ( ( ::bisect(bad) - ::bisect(good) ) | ( ::bisect(good) - ::bisect(bad) ) ) - bisect(range) - all ancestors of bad csets that are not ancestors of good csets, or - all ancestors of good csets that are not ancestors of bad csets - but that are not in the bisection range.

hbisect.get: use simpler code with repo.set(), fix 'pruned' set Use repo.set() wherever possible, instead of locally trying to reproduce complex graph computations. 'pruned' now means 'all csets that will no longer be visited by the bisection'. The change is done is this very patch instead of its own dedicated one becasue the code changes all over the place, and the previous 'pruned' code was totally rewritten by the cleanup, so it was easier to just change the behavior at the same time. The previous series went in too fast for this cleanup pass to be included, so here it is. ;-) Signed-off-by: "Yann E. MORIN" <yann.morin.1998@anciens.enib.fr>

mdiff: speed up showfunc for large diffs This addresses the following issues with showfunc: - Silly usage of regular expressions. - Doing str.rstrip() needlessly in an inner loop. - Doing catastrophic backtracking when trying to find a function line. Finding function text is now at worst O(n lines in the old file), and at best close to O(n hunks).
