php - Local/Dev/Live deployment - best workflow -

-

situation

we our little company 3 people, each has localhost webserver , projects (previous , current) on 1 pc network shared disk. have virtual server, of our clients' sites , our site.

our standard workflow is:

coder pc → programmer localhost → dev domain (client.company.com)                                          ↓                                   live version (client.com)

it happens, there 2 or 3 guys working on same projects @ same time - 1 on dev version, 2 on localhost.

when finished, try synchronize files on dev version , ideally not mess (thanks ilmv:]) files, **knock knock* * doesn't happen often.

and 1 of deploys dev version on live webserver.

question

we looking way simplify workflow while updating websites - ideally sort of diff uploader or vcs (git/svn/vcs/...), not sure begin or way ideal, therefore ask you, fellow stackoverflowers experience website / application deployment , recommended workflow.

we need use mac in process, if won't problem, better.

thank you

edit: 1 of crucial parts moving website dev live after working update. edit: check maxvt's answer if no other appear :)

it involved question, there 3 major improvements need make improve processes.

use version control

if projects on shared disk, assume there's folder current state of each project. easy developers overwrite each other's changes, there's no history, , can't sure if project in consistent state or broken.

choose version system , start using it. it's less important 1 (of free ones - svn ok , more "centralized", git or mercurial great , allow greater flexibility), it's more important change, no matter how small, goes through version control.

simplify promotion, deployment , rollback

there sequence of steps needed move localhost dev, , dev production - synchronize files, restore database known state, configure server-specific settings... there may document describing needs done, or tribal knowledge. goal should begin simplifying , automating that, achieving single command or script work needed synchronize server (local, dev or production) revision of project in source control.

by automating deployment, can sure necessary actions done in proper order, , not have mistakes in deployment can happen when files correct configuration or command not run, breaking site.

introduce testing

how know revision you've deployed not compiles properly, works expected? each non-trivial project, should have tests verify important functionality (login, adding stuff, producing reports, etc.) make sure changes made developers left site operating properly.

there testing frameworks testing web apps (selenium comes mind). study them , apply them. ideally testing suite run part of one-liner deployment script.

once have done those, you've come long way having orderly, predictable, , resilient development process. clients , developers thank :)

javascript - Enclosure Memory Copies -

-
function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

php - Replacing tags in braces, even nested tags, with regex -

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
