mercurial - File in repository after clone, but no history -

-

we have mercurial repository converted subversion while ago , have today noticed there files in repository have no history whatsoever.

one of sympomts of behaviour hg status reports file clean, while hg log reports no changesets same file:

> hg clone [repo] > hg st -c filewithmissinghistory.cs  c  filewithmissinghistory.cs  > hg blame filewithmissinghistory.cs filewithmissinghistory.cs: no such file in rev [...] > hg log filewithmissinghistory.cs > hg log filewithmissinghistory.cs -f abort: cannot follow nonexistent file: "filewithmissinghistory.cs"  > hg log -v | grep filewithmissinghistory.cs  [gives output, there arechangesets mentioning file]

obviously filenames have been changed in example. i've tried using hg verify, command reports repo fine. has experienced , there bring history "back life"? placing dummy history on files in question acceptable, suboptimal.

edit: i've done more investigation , noticed "filewithmissinghistory.cs" renamed filename (hg copy + delete) in revision 238. if hg update -r238 , hg log on file @ revision not history. doing hg log on original file reports history expected, seems history somehow lost during copy (again, file renamed using hg copy, , changeset indicates file has been copied).

sounds strange, impossible. try debug issue update different revisions , check @ revision file appears in working copy first time. if in binary search fashion (similar how bisect extension works), should find revision introduces file after few updates.

this not solve problem, may in tracking down source.

javascript - Enclosure Memory Copies -

function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
