How can I use "git describe --match" sensibly in combination with a shallow clone? -

-

i using git describe driver versioning in application @ build time. looks like: git describe --always --dirty --match version*

i tag versions pattern version.1.2.3 , build figures out version of application based off last commit tagged version.* was. if haven't tagged given commit, version number ends version.1.14.3-24-ged66bf5, based of recent tag, how many commits since tag , git commit id.

this works me personally, i'm having problem doing builds off of shallow clone on ci server.

when using "shallow clone" option on git build in jenkins (i'm guessing it's doing "--depth=1"), "git describe" command no longer doing want do. version number ends being commit id - guess because there no tagged versions in shallow clone, --always parameter describe command ends spitting out commit id.

i can deal moment not doing shallow clone.

but driving versioning off of git describe - how can keep using shallow clones? think need able specify @ time of shallow clone, want depth "from tip of branch latest version has tag matching version.*".

is thing can git?

you can't: shallow clone missing tag objects , commits tag.

more precisely, depends on depth of clone , how far 1 must go in history find appropriate tags. making shallow clone --depth 1000 might suffice, instance. precise number depends on how many commits have between1 tags care about.

you correct if git provided "deepen until tagged", trick, git doesn't, , worse, deepening shallow clone not automatically bring on tags.

(it possible write script uses git ls-remote , git fetch --depth keep deepening clone until tagged commit(s) appear, have script apply tags manually, were. take few dozen lines of python or shell code, instance, depending on how robust wanted it. it's not included git itself.)

1the notion of "between" bit iffy in non-linear graph, general idea should clear enough here, think.

java - Copying object fields -

what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
