On Windows, use the directory in which the binary resides as the
directory in which global data files are stored. If an installed binary
is being run, that's the correct directory for them; if a build-tree
binary is being run, the "manuf" file will be there, and you can put
other data files there as well, if necessary.
Do the same with plugins, except that, if there's no
"plugins\\{version}" subdirectory of that directory, fall back on the
default installation directory, so you at least have a place where you
can put plugins for use by build-tree binaries. (Should we, instead,
have the Windows build procedure create a subdirectory of the "plugins"
source directory, with the plugin version number as its name, and copy
the plugins there, so you'd use the build-tree plugin binaries?)
Move "test_for_directory()" out of "util.c" and into
"epan/filesystem.c", with the other file system access portability
wrappers and convenience routines. Fix "util.h" not to declare it - or
other routines moved to "epan/filesystem.c" a while ago.

On Windows, use the directory in which the binary resides as the
directory in which global data files are stored. If an installed binary
is being run, that's the correct directory for them; if a build-tree
binary is being run, the "manuf" file will be there, and you can put
other data files there as well, if necessary.
Do the same with plugins, except that, if there's no
"plugins\\{version}" subdirectory of that directory, fall back on the
default installation directory, so you at least have a place where you
can put plugins for use by build-tree binaries. (Should we, instead,
have the Windows build procedure create a subdirectory of the "plugins"
source directory, with the plugin version number as its name, and copy
the plugins there, so you'd use the build-tree plugin binaries?)
Move "test_for_directory()" out of "util.c" and into
"epan/filesystem.c", with the other file system access portability
wrappers and convenience routines. Fix "util.h" not to declare it - or
other routines moved to "epan/filesystem.c" a while ago.

Add a routine to attempt to get the absolute pathname of the executable
file, strip off the last component to get the pathname of the directory
containing the executable file, and save it for future use. On Windows,
you can get that from the OS, but, on UN*X, you have to look at argv[0]
and derive the absolute path from that (argv[0] is not guaranteed to be
an absolute path, or even a path at all). (In addition, if you're
running from the build directory, you might have to strip off a ".libs/"
added to argv[0] as an artifact of the libtoolizing script.)
Use that in the About dialog, and use it to construct the path of
dumpcap.
Don't put quotes into the path of dumpcap; you don't have to quote
strings with spaces in them when handing them to execvp and, in fact,
you *mustn't* quote them, as the quotes will be treated as part of the
pathname.

|
|
|
|
*
|

* so if we were to ship with any frameworks (e.g. Qt) we should

|

|
|

*
|
|
|
|
* Contains loadable bundles that extend the basic features of your

|
|
* application. You use this directory to include code modules that

|
|
|
|
* executables.
|
|
|
|
*
|
|
|
|
* Our plugins are just raw .so/.dylib files; I don't know whether by
|
|
|
|
* "bundles" they mean application bundles (i.e., directory hierarchies)
|
|
|
|
* or just "bundles" in the Mach-O sense (which are an image type that

|

|
* are, I think, built as dylibs and can be loaded either way).

|
*
|

|
|
* Contains additional non-critical resources that do not impact the

|
|
|
* ability of the application to run. You might use this directory to
|
|
|
|
* include things like document templates, clip art, and tutorials
|

* that your application expects to be present but that do not affect

|

|
|
|
|
*
|
|
|
|
* I don't think I'd put the files that currently go under Resources/share
|
|
|
|
* into that category; they're not, for example, sample Lua scripts that
|
|
|
|
* don't actually get run by Wireshark, they're configuration/data files

* for Wireshark whose absence might not prevent Wireshark from running

On Windows, use the directory in which the binary resides as the
directory in which global data files are stored. If an installed binary
is being run, that's the correct directory for them; if a build-tree
binary is being run, the "manuf" file will be there, and you can put
other data files there as well, if necessary.
Do the same with plugins, except that, if there's no
"plugins\\{version}" subdirectory of that directory, fall back on the
default installation directory, so you at least have a place where you
can put plugins for use by build-tree binaries. (Should we, instead,
have the Windows build procedure create a subdirectory of the "plugins"
source directory, with the plugin version number as its name, and copy
the plugins there, so you'd use the build-tree plugin binaries?)
Move "test_for_directory()" out of "util.c" and into
"epan/filesystem.c", with the other file system access portability
wrappers and convenience routines. Fix "util.h" not to declare it - or
other routines moved to "epan/filesystem.c" a while ago.

Use that in the About dialog, and use it to construct the path of
dumpcap.
Don't put quotes into the path of dumpcap; you don't have to quote
strings with spaces in them when handing them to execvp and, in fact,
you *mustn't* quote them, as the quotes will be treated as part of the

default installation directory, so you at least have a place where you
can put plugins for use by build-tree binaries. (Should we, instead,

the plugins there, so you'd use the build-tree plugin binaries?)
Move "test_for_directory()" out of "util.c" and into
"epan/filesystem.c", with the other file system access portability

On Windows, use the directory in which the binary resides as the
directory in which global data files are stored. If an installed binary
is being run, that's the correct directory for them; if a build-tree
binary is being run, the "manuf" file will be there, and you can put
other data files there as well, if necessary.
Do the same with plugins, except that, if there's no
"plugins\\{version}" subdirectory of that directory, fall back on the
default installation directory, so you at least have a place where you
can put plugins for use by build-tree binaries. (Should we, instead,
have the Windows build procedure create a subdirectory of the "plugins"
source directory, with the plugin version number as its name, and copy
the plugins there, so you'd use the build-tree plugin binaries?)
Move "test_for_directory()" out of "util.c" and into
"epan/filesystem.c", with the other file system access portability
wrappers and convenience routines. Fix "util.h" not to declare it - or
other routines moved to "epan/filesystem.c" a while ago.

Add a routine to attempt to get the absolute pathname of the executable
file, strip off the last component to get the pathname of the directory
containing the executable file, and save it for future use. On Windows,
you can get that from the OS, but, on UN*X, you have to look at argv[0]
and derive the absolute path from that (argv[0] is not guaranteed to be
an absolute path, or even a path at all). (In addition, if you're
running from the build directory, you might have to strip off a ".libs/"
added to argv[0] as an artifact of the libtoolizing script.)
Use that in the About dialog, and use it to construct the path of
dumpcap.
Don't put quotes into the path of dumpcap; you don't have to quote
strings with spaces in them when handing them to execvp and, in fact,
you *mustn't* quote them, as the quotes will be treated as part of the
pathname.
