SpiderMonkey was updated to mozjs24. If you want to build elinks
with ecmascript support, you must compile using g++ with -fpermissive .
There is a lot of warnings.
There are some memleaks in ecmascript code, especially related to JSAutoCompartment.
I don't know yet, where and how to free it.
Debian does not support mozjs24, so I'm going to gradually update SpiderMonkey version.
Weak points:
- alignof
- js problems
Todo:
- make js work with C++ and mozjs-17
- then mozjs-24
- then mozjs-52
- then mozjs-60
- decrease number of warnings

DELETED:
* dumb {b}, smart {bb, bb_fr_en, bb_en_fr}: Redirects to Microsoft
Translator, which I can't get to work without JavaScript. Deleted.
* dumb {pyhelp}, smart {py, pydev}: Deleted as recommended by the
author of the CGI script.
* dumb {pyvault, lyrics}, smart {pyvault}: Can't find a new URL for the
service. Deleted.
* smart {gd}: Google Directory has been shut down. Deleted.
* smart {sd, sdc, sdu, sdp, sdj, whatis}: These don't seem to work
without JavaScript. Deleted.
* smart {id, draft}: The search still exists but I can't get it to
take the words from the URL. Deleted.
UPDATED:
* dumb {cia}: Had changed its URL, and the service is down, but they
intend to restore it. Updated and kept.
* dumb {lua}: ELinks no longer supports Lua 4.0. Changed to 5.1 as
installed by Debian.
* smart {cliki, foldoc, gwho, gwhat, gwhere, gwhen, a, imdb, wn, fsd,
rfcs, cr}: Updated URLs.
Doxygen warned that <uri> is an unsupported xml/html tag.
It was not intended as a tag though; rather as a placeholder
akin to <var>uri</var>. Escape with a backslash.
In almost all calls to parse_header, the second argument is a string
literal: parse_header(head, "Charset", NULL) for example.
Of course, parse_header does not write to that string. Accordingly,
make the parameter point to const, so calls that use a variable rather
than a string literal can make that variable point to const too.
Leaving the other parameters non-const for now.
http_negotiate_parse_data passed &token->length as the int *outlen
parameter of base64_decode_bin, which stores an int at that location.
However, gss_buffer_desc::length is size_t in all implementations that
I checked: MIT Kerberos Version 5 Release 1.10, libgssglue 0.4, and
GNU GSS 1.0.2. This mismatch could cause the build to fail:
.../src/protocol/http/http_negotiate.c: In function ‘http_negotiate_parse_data’:
.../src/protocol/http/http_negotiate.c:173:2: error: passing argument 3 of ‘base64_decode_bin’ from incompatible pointer type [-Werror]
In file included from .../src/protocol/http/http_negotiate.c:30:0:
.../src/util/base64.h:8:16: note: expected ‘int *’ but argument is of type ‘size_t *’
On 64-bit big-endian hosts, it might also cause the GSSAPI
implementation to read too much data from memory and disclose it to
some network server, or crash ELinks.

INIT_OPTION used to initialize union option_value at compile time by
casting the default value to LIST_OF(struct option) *, which is the
type of the first member. On sparc64 and other big-endian systems
where sizeof(int) < sizeof(struct list_head *), this tended to leave
option->value.number as zero, thus messing up OPT_INT and OPT_BOOL
at least. OPT_LONG however tended to work right.
This would be easy to fix with C99 designated initializers,
but doc/hacking.txt says ELinks must be kept C89 compatible.
Another solution would be to make register_options() read the
value from option->value.tree (the first member), cast it back
to the right type, and write it to the appropriate member;
but that would still require somewhat dubious conversions
between integers, data pointers, and function pointers.
So here's a rather more invasive solution. Add struct option_init,
which is somewhat similar to struct option but has non-overlapping
members for different types of values, to ensure nothing is lost
in compile-time conversions. Move unsigned char *path from struct
option_info to struct option_init, and replace struct option_info
with a union that contains struct option_init and struct option.
Now, this union can be initialized with no portability problems,
and register_options() then moves the values from struct option_init
to their final places in struct option.
In my x86 ELinks build with plenty of options configured in, this
change bloated the text section by 340 bytes but compressed the data
section by 2784 bytes, presumably because union option_info is a
pointer smaller than struct option_info was.

Conflicts:
src/protocol/fsp/fsp.c: All options had been removed in 0.13.GIT.
src/protocol/smb/smb2.c: Ditto.
... and mention that URI rewriting rules may leak ELinks' identity
in the documentation of protocol.http.user_agent.
Originally requested at <https://bugzilla.redhat.com/856348>.
read_http_post_inline decodes two hexadecimal digits into one byte at
a time, and it asserts that each hexadecimal digit is valid; however,
both assertions print the first digit when they fail. Fix the assertion
on the second digit to print the second digit.
