git log restricted to path doesn't show expected commit -


i noticed behavior of git don't understand in this repository. can cloned via:

git clone "git@github.com:skript-sicherheit/skript.git"

if navigate folder images in terminal , execute git log ., prints this:

commit b1703a7542ee226535a34bd3de9aed48a7f76a8d author: lukas beeck <meisterasrael@googelmail.com> date:   wed sep 7 10:37:39 2016 +0200      bild von mona lisa war verschwunden, ist wieder drin  commit 0e3ede155080a3005e6454d855e18dc0083ea01a author: lukas beeck <meisterasrael@googelmail.com> date:   fri sep 2 10:20:25 2016 +0200      erläuterung in grafik eingefügt  [...]

git show b1703a7542ee226535a34bd3de9aed48a7f76a8d prints:

commit b1703a7542ee226535a34bd3de9aed48a7f76a8d author: lukas beeck <meisterasrael@googelmail.com> date:   wed sep 7 10:37:39 2016 +0200      bild von mona lisa war verschwunden, ist wieder drin  diff --git a/images/mona-lisa.jpg b/images/mona-lisa.jpg new file mode 100644 index 0000000..f4f5583 binary files /dev/null , b/images/mona-lisa.jpg differ

the commit message german for: "image of mona lisa had vanished. in again."

so clearly, file mona-lisa.jpg changed b1703a7542ee226535a34bd3de9aed48a7f76a8d. file changed it.

but if execute git log mona-lisa.jpg, (entire) output:

commit 669b00871f3dba5c43ac7d53e44f317a61b177d0 merge: 921a31c 519cdae author: lukas beeck <meisterasrael@googelmail.com> date:   fri sep 2 15:39:00 2016 +0200      merge branch 'index'

why doesn't b1703a7542ee226535a34bd3de9aed48a7f76a8d appear in output of command?

more of comment satisfactory answer, looks strange sequence of events in repository. can, situation:

master             | .. -> -> b -> [e] (mona lisa) -> .. -> [h]                    |                 /                        / index              |     .. -> c -> d                        /                      |                                        / seitenkanalgriffe  |                .. -> f (mona lisa) -> g

it seems reason, mona lisa image added in merge commit e; guess maybe untracked image accidentally in directory @ time , added error.

the actual branch seems have been intentionally committed in, seitenkanalgriffe branch, not merged until h.

the git log documentation when specifying path states:

[--] <path>…​

show commits enough explain how files match specified paths came be. see history simplification below details , other simplification modes.

paths may need prefixed ‘`-- '’ separate them options or revision range, when confusion arises.

since important commit in terms of file history e, commit introduced image, , h made no changes file, see e when running git log mona-lisa.jpg. e commit "merge branch 'index'" comment mention in question.

to further confuse things, if use git log --follow images/mona-lisa.jpg, see commit h, because won't follow file in merges default. you'll have run git log --follow -m images/mona-lisa.jpg see commits e , h listed.

that @ least, understanding of going on here, there may else blame.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...
