open source - Updating Self-Installed PHP files? -

-

i in final stages of completing project (vizulium - open-source photography cms). have 1 final remaining stumbling block: updating software.

my idea wanting implement this:

  1. check newest version @ vizulium website (page displays current stable version).
  2. if newer version exists, , user requests it:
    a. zip updated files on vizulium server
    b. download files user's server
    c. unzip contents

i have tracking system in place keeps track of updates (datetime) push. have not began step 2. in php , mysql.

is typical implementation of problem? need clarify anything?

i not using ftp since self-install , assume user programming-illiterate.

your solution valid, needs few considerations.

you should connect server via https , certificate verification query , fetch available updates.

you should sign updates private key , have client verify updates authentic before applying them.

if need remove obsolete file install, unzipping not this, perhaps have "upgrade.php" script in each upgrade executed perform necessary steps.

your upgrade script should backup web directory , database before performing upgrade, , retain backup until user requests remove it.

make upgrades incremental, upgraded 1 -> 3, need upgrade version 2 first. of-course transparent user, ensure upgrades between versions complete , database updates/modifications applied in correct order.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
