during merge commit creation. if change not staged , left outside merge commit.(this happen, , happens lot when doesn't quite known he's doing, blindly type mystery commands. or due misclick on gui git tool.[they non-technician, tried teach them, failed. let them use git can update files , keep date.]) change gone. merge commit won't have this change undoed msg. doesn't appear in merge commit. commit made change has info change. after merge change undoed without trace. this horrifying, can't rely on merge commit info tell has been changed/undoed. in fact there's no easy way tell. one approach solve limit ability merge onto master trustworthy maintainers.but fast developing mini group, add burden maintainer , slow down. i'm wondering there enforce merge commit include info changes reverted not recorded? or can ban merge operation completely, allow rebase make sure changes recorded explicitly? no automated source tool can totally foolpro

i've noticed recently, since installing rails 5 local_time gem doesn't work on pages link internal (through turbolinks). if link page external or browser refreshed, or turbolinks disabled, local_time works properly. does know how use these together? i needed initialize local time on turbolinks load. event provides chance things have run @ document ready. javascript is: document.addeventlistener("turbolinks:load", function() { localtime.run(); });

so creating huffman tree, , having hard time overriding function, , believe due covariance issue. here hierarchy having hard time in code: class treeinterface { public: treeinterface() {} virtual ~treeinterface() {} virtual nodeinterface * getrootnode() const = 0; }; class tree : treeinterface { public: tree() {} virtual ~tree() {} node* getrootnode() { return treeroot; } private: node* treeroot; }; those work fine, next block has issues. class huffmaninterface{ public: huffmaninterface() {} virtual ~huffmaninterface() {} virtual bool createtree(string filename) = 0; virtual string encodemessage(string toencode) = 0; virtual treeinterface * gettree() = 0; virtual map<char, string> getencodings() = 0; }; class huffman : huffmaninterface{ public: huffman() {} ~huffman() {} bool huffman::createtree(string filename){ } string huffman::encodemessage(string toencode){ } str

i have tcl utility makes easy ensure snippet of code run @ time control flow leaves current scope (of proc ). crashes in tcl 8.6.6, i'm wondering if there "better" way implement functionality in tcl 8.6? an example usage is: proc test {file} { set fh [open $file] ::util::defer [list close $fh] # ... bunch of stuff # , if hit error # [close $fh] evaluated return # proc } it's worked great in tcl 8.4, , use on code. as i'm still coming speed on functionality available in tcl 8.6, i'm asking how should ::util::defer proc written best take advantage of tcl 8.6? here 8.4 implementation: namespace eval ::util {} proc ::util::defer_impl {cmd args} { uplevel 1 $cmd } proc ::util::defer {cmd} { set vname _u_defer_var # unique variable name while {[uplevel 1 [list info vars $vname]] != ""} { set vname ${vname}_ } uplevel 1 [list set $vname $cmd] # when variable unset, trigger call command uplevel 1 [list

i have been working on first project using databases using mysql. woke morning unable login localhost. able enter root no password , none of databases there. should do? in theory root should have access databases. if haven't deleted them, it's possible lost access them. remember mysql host-sensitive when logging in. root@% , root@localhost , root@10.0.0.1 , etc... may assigned different permissions. you can try skip-grant-table in my.ini , explained in answer: regaining access lost mysql password phpmyadmin on wamp with can reset root password , try again. if not yield effect, sql history , see if haven't accidentally deleted them?
