2014-07-15Rework permission handlingLukas Fleischer1-10/+1
Add a new function has_credential() that checks whether the currently logged in user is allowed to perform a given action. Moving all permission handling to this central place makes adding new user groups and adjusting permissions much more convenient. Signed-off-by: Lukas Fleischer <archlinux@cryptocrack.de>

2014-06-05Do not return "None" in user functionsLukas Fleischer1-20/+24
Return null instead of the string "None" in username_from_id(), uid_from_email() and uid_from_username(). Signed-off-by: Lukas Fleischer <archlinux@cryptocrack.de>

2014-05-03Fix parsing of array overridesLukas Fleischer1-4/+11
If a depends (makedepends, checkdepends, optdepends, conflicts, provides, replaces, license, groups, source) line appears in a package section, it replaces the corresponding array from the pkgbase section. If there is a single "depends = " line in the package section, the depends array of that package is considered empty. This partly reverts the behavior introduced in commit 137a9ae (Fix parsing of array overrides, 2014-05-03). Signed-off-by: Lukas Fleischer <archlinux@cryptocrack.de>
2014-04-19Handle pkgbase array overrides gracefullyLukas Fleischer1-0/+25
Instead of overwriting arrays, such as depends, from the pkgbase section, new entries should be appended. Replace array_merge() with a mixture of array_merge_recursive() and array_replace_recursive() that merges array fields and replaces non-array fields. Signed-off-by: Lukas Fleischer <archlinux@cryptocrack.de>
2014-04-05Do not allow for overwriting arbitrary packagesLukas Fleischer1-0/+19
A package should only be overwritten if it already belongs to the package base that is trying to overwrite it. Signed-off-by: Lukas Fleischer <archlinux@cryptocrack.de>
2014-04-05Add provisional support for package basesLukas Fleischer1-13/+2
This adds a PackageBases table to the database schema and moves the following fields from the Packages table to PackageBases: * CategoryID * NumVotes * OutOfDateTS * SubmittedTS * ModifiedTS * SubmitterUID * MaintainerUID It also fixes all database accesses to comply with the new layout. Having a separate PackageBases table is the first step to split package support. By now, we create one PackageBases entry per package (where the package base has the same name as the corresponding package). When adding full support for split packages later, the package base name will be derived from the pkgbase variable and a single package base will be shared amongst all packages built from one source package.

2013-02-10Remove checks before calling connection methodcanyonknight1-45/+15
Large amount of boilerplate code that checks if a database connection exists is useless now that the new connection method automatically does the same check. Signed-off-by: canyonknight <canyonknight@gmail.com> Signed-off-by: Lukas Fleischer <archlinux@cryptocrack.de>

2013-02-10Remove unnecessary database connection parameter from all functionscanyonknight1-17/+17
All functions now have a database connection method that will use the same database connection. This imitates the functionality of passing a database connection as an argument and makes it redundant.

2013-02-10Add database wrapper class and new connection methodcanyonknight1-33/+16
Uses the Singleton pattern to ensure all queries use the same database connection that is released upon script completion. All database connections should now be called with DB::connect() and not db_connect(). Signed-off-by: canyonknight <canyonknight@gmail.com> Signed-off-by: Lukas Fleischer <archlinux@cryptocrack.de>

2012-09-24aur.inc.php: Document all functions using PHPDoc formatcanyonknight1-40/+191

2012-09-18Migrate all DB code to use PDOcanyonknight1-101/+53
All DB code currently uses the quickly aging mysql_* functions. These functions are strongly discouraged and may eventually be deprecated. Transition all code to utilize the PDO data access abstraction layer. PDO allows for consistent query code across multiple databases. This could potentially allow for someone to use a database other than MySQL with minimal code changes. All functions and behaviors are reproduced as faithfully as possible with PDO equivalents and some changes in code.

2012-06-24Implement token system to fix CSRF vulnerabilitiescanyonknight1-0/+10
Specially crafted pages can force authenticated users to unknowingly perform actions on the AUR website despite being on an attacker's website. This cross-site request forgery (CSRF) vulnerability applies to all POST data on the AUR. Implement a token system using a double submit cookie. Have a hidden form value on every page containing POST forms. Use the newly added check_token() to verify the token sent via POST matches the "AURSID" cookie value. Random nature of the token limits potential for CSRF. Signed-off-by: canyonknight <canyonknight@gmail.com> Signed-off-by: Lukas Fleischer <archlinux@cryptocrack.de>

this can be used as an intermediate 'patch' util there is a validation system in place. the extra check is to verify that the domain part of a correctly formatted email address is existing and in use. this will not at all stop spammers since they can use bogus emails with valid domain parts Lukas: Minor formatting changes.

2011-11-02Add a new AUR_LOCATION settingDan McGee1-0/+1
This should be set to something like 'http://localhost' for development or 'https://aur.archlinux.org' in production. It ensures all links in the site stay in the development site and there is no sudden jump from development to production environments.

2011-10-25Escape wildcards in "LIKE" patternsLukas Fleischer1-0/+5
Percent signs ("%") and underscores ("_") are not escaped by mysql_real_escape_string() and are interpreted as wildcards if combined with "LIKE". Write a wrapper function db_escape_like() and use it where appropriate. Note that we already fixed this for the RPC interface in commit da2ebb667b7a332ddd8d905bf9b9a8694765fed6 but missed the other places. This patch should fix all remaining flaws reported in FS#26527.

Wrap mysql_real_escape_string() in a wrapper function db_escape_string() to ease porting to other databases, and as another step to pulling more of the database code into a central location.

2011-08-11aur.inc.php: allow all functions using DB to take handle as argDan McGee1-25/+49
This prevents needless calls to db_connect() if we already have a reference to a handle we can pass into a function. Although the current underlying implementation using mysql_connect() will return the same connection if all parameters are the same, this might not be true if we switch to a more modern (e.g. PDO) interface. In the face of safe transactions, it is extremely important all actions are being taken over the same connection to the database.

2011-06-25Simplify session ID generationLukas Fleischer1-10/+1
There was too much voodoo going on in new_sid(). Just use uniqid() with a random seed and the optional entropy parameter to generate MD5 input. Use the remote IP address as a salt to reduce the chance of two clients getting the same ID if they login at exactly the same time.
