Locked packages are basically like removable fixed packages, so we still
only load one version, but we do not require their installation unless
something the user needs requires their use. So they automatically get
removed if they are no longer needed on any update.
The only automatic conflict we have results from packages using the same name
either by literally having the same name and being different versions or they
replace the same name, so
- removed all types of obsolete rules
- simplified rule generation significantly
- got rid of provide filtering in the pool
- fixed some language in error handling
The only type of request job remaining was "install" which is really a
root requirement. The only other kind of input for the solver is now a
set of fixed packages.
Rules have been updated to account for only two kinds of former job
reason: FIXED or ROOT_REQUIRE. The job property has always been
redundant and has been removed, since reasonData suffices.
Problem reasons are always rules, so the unnecessary wrapping in an
array has been removed.
We now only ever generate a single rule per root require or fixed
package, so there is no need for the solver to special handle disabling
"jobs" anymore, the rule can just be disabled as usual.
For consistency special handling of rules for jobs in problems has been
integrated into the rule class like all other rule reasons. As part of
this change the error message for root requirements has been improved a
bit to make it clearer where the package installation request came from.
The word job has also been removed from operations, which are called
operations, not jobs.
- Introduce separate Lock and LocalRepo transactions, one for changes
to the lock file, one for changes to locally installed packages based
on lock file
- Remove various hacks to keep dev dependencies updated and
incorporated the functionality into the transaction classes
- Remove installed repo, there are now local repo, locked repo and
platform repo
- Remove access to local repo from solver, only supply locked packages
- Update can now be run to modify the lock file but not install packages
to local repo

Support identifying the HHVM version when not running with HHVM
hhvm-nightly (and next week's release) now report 4.x, so all the 3.x
constraints are now giving misleading error messages with this patch.
Before:
```
- facebook/fbexpect v2.3.0 requires hhvm ^3.28 -> you are running this with PHP and not HHVM.
```
After:
```
- facebook/fbexpect v2.3.0 requires hhvm ^3.28 -> your HHVM version (4.0.0-dev) does not satisfy that requirement.
```
Pool construction depends on the install request now, so only required
packages get loaded, add some structure for future asynchronously
loading composer repositories
According to type 2nd constructor-argument `$reasonData` can either be a Link or a PackageInterface. IDEs like PhpStorm won't be able to provide autocompletion since both classes are from a different namespace.
In order to provide better autocompletion for `$reasonData` and by extension `$this->reasonData` the use statements should be included or the type hint should use the fully qualified class name.
For the same reason I added the docblock on the protected method `formatePackagesUnique()`.
It is known that composer update takes a lot of memory: #5915, #5902,
I am playing with a profiler (@blackfireio) to make a demo in my local
PHP meetup (@phpvigo) and I found out a way to use less memory. These
are my first tests:
* Private project using PHP 5.6:
* Memory: from 1.31GB to 1.07GB
* Wall Time: from 2min 8s to 1min 33s
* symfony-demo using PHP 7.1 in my old mac book:
* Memory: from 667MB to 523MB
* Wall Time: from 5min 29s to 5min 28s
Not use an array inside conflict rules is this improvement main idea:
```php
<?php
//Memory 38MB
gc_collect_cycles();
gc_disable();
class Rule
{
public $literals;
public function __construct(array $literals)
{
$this->literals = $literals;
}
}
$rules = array();
$i = 0;
while ($i<80000){ //
$i++;
$array = array(-$i, $i);
$rule = new Rule($array);
$rules[] = $rule;
}
```
```php
<?php
//Memory 11.1MB
gc_collect_cycles();
gc_disable();
class Rule2Literals
{
public $literal1;
public $literal2;
public function __construct($literal1, $literal2)
{
$this->literal1 = $literal1;
$this->literal2 = $literal2;
}
}
$rules = array();
$i = 0;
while ($i<80000){ //
$i++;
$rule = new ConflictRule(-$i, $i);
$rules[] = $rule;
}
```
