ValExtLinks: The 'I Just Broke All The Diff-Gazing' Commit. Revised file structure of the project and added the MIT license. Revised all documentation. HTTP and curl codes are now wiki-formatted and hosted online. In Val itself, I made these changes: Added --timeout argument to change default URL query timeout of 10 seconds. Revised the report header to be easier to read. Less advice is printed directly in the report and more is online at the location linked to under the Legend section.

[1139]1ValExtLinks uses the Unix tool 'curl' to query each link. These are the return values which can come from 'curl', taken from its man page. These codes appear in parentheses after the three-digit [[../HTTP codes|HTTP response code]] for each link (except EI and IW links).

3<pre>EXIT CODES
4 1 Unsupported protocol. This build of curl has no support for this
5 protocol.
6
7 2 Failed to initialize.
8
9 3 URL malformed. The syntax was not correct.
10
11 4 A feature or option that was needed to perform the desired
12 request was not enabled or was explicitly disabled at build-
13 time. To make curl able to do this, you probably need another
14 build of libcurl!
15
16 5 Couldn't resolve proxy. The given proxy host could not be
17 resolved.
18
19 6 Couldn't resolve host. The given remote host was not resolved.
20
21 7 Failed to connect to host.
22
23 8 Weird server reply. The server sent data curl couldn't parse.
24
25 9 FTP access denied. The server denied login or denied access to
26 the particular resource or directory you wanted to reach. Most
27 often you tried to change to a directory that doesn't exist on
28 the server.
29
30 10 FTP accept failed. While waiting for the server to connect back
31 when an active FTP session is used, an error code was sent over
32 the control connection or similar.
33
34 11 FTP weird PASS reply. Curl couldn't parse the reply sent to the
35 PASS request.
36
37 12 During an active FTP session while waiting for the server to
38 connect back to curl, the timeout expired.
39
40 13 FTP weird PASV reply, Curl couldn't parse the reply sent to the
41 PASV request.
42
43 14 FTP weird 227 format. Curl couldn't parse the 227-line the
44 server sent.
45
46 15 FTP can't get host. Couldn't resolve the host IP we got in the
47 227-line.
48
49 16 HTTP/2 error. A problem was detected in the HTTP2 framing layer.
50 This is somewhat generic and can be one out of several problems,
51 see the error message for details.
52
53 17 FTP couldn't set binary. Couldn't change transfer method to
54 binary.
55
56 18 Partial file. Only a part of the file was transferred.
57
58 19 FTP couldn't download/access the given file, the RETR (or simi-
59 lar) command failed.
60
61 21 FTP quote error. A quote command returned error from the server.
62
63 22 HTTP page not retrieved. The requested url was not found or
64 returned another error with the HTTP error code being 400 or
65 above. This return code only appears if -f, --fail is used.
66
67 23 Write error. Curl couldn't write data to a local filesystem or
68 similar.
69
70 25 FTP couldn't STOR file. The server denied the STOR operation,
71 used for FTP uploading.

76
77 28 Operation timeout. The specified time-out period was reached
78 according to the conditions.
79
80 30 FTP PORT failed. The PORT command failed. Not all FTP servers
81 support the PORT command, try doing a transfer using PASV
82 instead!
83
84 31 FTP couldn't use REST. The REST command failed. This command is
85 used for resumed FTP transfers.
86
87 33 HTTP range error. The range "command" didn't work.

113 mum amount.
