Git submodule update: reference is not a tree... but commit IS there -


first of all: yes, i've checked this thread inside out - situation different.

we have 3 modules here:

  • an application a
  • its base library b (a submodule of a)
  • a component c (a submodule of b)

when trying git clone --recursive https://url_of_a/, error when git attempts fetch c:

cloning 'path/of/c'... [...] checking connectivity... done fatal: reference not tree: 92405dd9027a2d55d9dd6f5b26494eee0009e297 unable checkout '92405dd9027a2d55d9dd6f5b26494eee0009e297'     in submodule path 'path/to/c'

but guess what, there's no error when git clone --recursive https://url_of_b/ - though the revision check out same:

cloning 'path/of/c'... checking connectivity... done submodule path 'path/to/c': checked out '92405dd9027a2d55d9dd6f5b26494eee0009e297'

... though remote pathes c same!

what's more puzzling: behavior observed @ windows 7/8 machines (so far, @ least). windows vista/xp machines somehow deep cloning same repositories without glitches - , wonder how's can platform-dependent.

that's case, questions: 1) there same problem, , 2) workarounds? note all components (a, b, , c) not under our control, 'switch git-tree' , stuff won't work, unfortunately.

as first (incomplete) answer, lot of submodule corrections went between git 1.8.4 , 1.8.5.2:

c:\users\vonc\prog\git\git>git log -ssubmodule v1.8.4..v1.8.5.2

it possible 1 of patches enhances robustness of submodule feature.
instance, msysgit issue you mention (issue 99) solved commit 4b054402833.

html - Sizing a high-res image (~8MB) to display entirely in a small div (circular, diameter 100px) -

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .

identifier - Is it possible for an html5 document to have two ids? -

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
