4 How to configure a Phabricator development environment.
9 There are some options and workflows that may be useful if you are developing
10 or debugging Phabricator.
16 To adjust Phabricator for development:
18 - Enable `phabricator.developer-mode` to enable some options and show
19 more debugging information.
20 - Enable `phabricator.show-prototypes` to show all the incomplete
22 - See @{article: Using DarkConsole} for instructions on enabling the
29 Errors normally go to DarkConsole (if enabled) and the webserver error log,
30 which is often located somewhere like `/var/log/apache/error_log`. This file
31 often contains relevant information after you encounter an error.
33 When debugging, you can print information to the error log with `phlog(...)`.
34 You can `phlog(new Exception(...))` to get a stack trace.
36 You can print information to the UI with `throw new Exception(...)`,
37 `print_r(...)`, or `var_dump(...)`.
39 You can abort execution with `die(...)` if you want to make sure execution
40 does not make it past some point. Normally `throw` does this too, but callers
41 can `catch` exceptions; they can not catch `die(...)`.
47 After adding, renaming, or moving classes, run `arc liberate` to rebuild
51 phabricator/ $ arc liberate
54 Until you do this, Phabricator won't recognize your new, moved, or renamed
55 classes. You do not need to run this after modifying an existing class.
57 After any modifications to static resources (CSS / JS) but before sending
58 changes for review or pushing them to the remote, run `bin/celerity map`:
61 phabricator/ $ ./bin/celerity map
64 This rebuilds the static resource map.
66 If you forget to run these commands you'll normally be warned by unit tests,
67 but knowing about them may prevent confusion before you hit the warnings.
73 Almost every script supports a `--trace` flag, which prints out service
74 calls and more detailed error information. This is often the best way to get
75 started with debugging command-line scripts.
81 Although it is more user-focused than developer-focused, the
82 @{article:Troubleshooting Performance Problems} guide has useful information
83 on the tools available for diagnosing and understanding performance problems.
89 If you're working with applications that support custom domains (like Phurl or
90 Phame) you can normally test them by adding more entries to your webserver
91 configuration that look exactly like the primary entry (or expanding the
92 primary entry to match more domains).
94 Phabricator routes all requests based on host headers, so alternate domains
95 do not normally need any kind of special configuration.
97 You may also need to add `/etc/hosts` entries for the domains themselves.
103 You can create test objects with the "Lipsum" utility:
106 phabricator/ $ ./bin/lipsum help generate
107 phabricator/ $ ./bin/lipsum generate ...
110 Test data can make your local install feel a little more realistic. With
111 `--quickly`, you can generate a large amount of test data to help test issues
112 with performance or scale.
