This PR just addresses some places where quotes need to be used to avoid word splitting in case the referenced file, or path to the file, contains space characters.
The previous fix did not work if testssl.sh was found via `$PATH`. This seems to work in all cases. If testssl.sh is found via `$PATH` or if the command line includes a path, then `which` returns a non-empty response; otherwise, `$0` does not include any path, but one needs to be provided, so `$RUN_DIR/$PROG_NAME` is used.
Using "$0" as the name of the executable seems to work as long as "$0" contains a directory name (e.g, "workingfiles/testssl.sh"), but not if it is just the name of the executable (e.g., "testssl.sh"). Specifying "$RUN_DIR/$PROG_NAME" seems to work in both cases, since if "$0" doesn't contain any path information, `$RUN_DIR` is `.`
Use the suggestion "If you want to print the argument list as close as possible to what the user probably entered" from http://stackoverflow.com/questions/10835933/preserve-quotes-in-bash-arguments to create `$CMDLINE` and to print the command lines in `run_mass_testing()` and `run_mass_testing_parallel()`.
This PR addresses issue #702. Rather than create the command line for each child process in `run_mass_testing()` as a string, it creates it as an array, with each argument being a separate element in the array. This was done based on http://mywiki.wooledge.org/BashFAQ/050.
The printing of each child's command line done based on http://stackoverflow.com/questions/10835933/preserve-quotes-in-bash-arguments.
The `$CMDLINE` string remains unchanged, even though it isn't entirely "correct," since http://jsonlint.com/ complains if the "Invocation:" string contains backslashes.
I was doing some testing on my extended_tls_sockets branch and discovered that it was not fully working since the `TLS13_KEY_SHARES` array was empty. According to https://lists.gnu.org/archive/html/bug-bash/2012-06/msg00068.html, there is an issue when trying to initialize a global array inside a function. (The current code initializes `TLS12_CIPHER`, `TLS_CIPHER`, and `TLS13_KEY_SHARES` within `get_install_dir()`, since tls_data.txt is read in that function.) In fact, according to http://stackoverflow.com/questions/10806357/associative-arrays-are-local-by-default, in order to initialize a global variable in a function, one needs to provide the `-g` option, which was only added in Bash 4.2.
This PR seems to fix the problem by moving the reading of tls_data.txt to the main body of the code rather than reading it within the `get_install_dir()` function.
If I understand correctly how `run_hpkp()` should be displaying the list of Backups, the problem shown in the photo attached to #696 occurred because the dangling SPKIs should have been printed on the next line. This PR fixes this by changing the code that prints out the "good" backups to include a newline after printing the CA's name.
Another problem this PR fixes is that `tm_italic()` is being called instead of `pr_italic()`, meaning that the italicized text is being printed to the terminal, but is not being included in the HTML output.
Finally, this PR fixes errors in the definitions of `tmln_italic()` and `prln_italic()`. `tmln_italic()` calls `outln()` and `prln_italic()` calls `tmln_out()` instead of the reverse.
This PR fixes issue #695 by changing the call to `out_row_aligned_max_width()` so that the length of the flag is considered in determining the length of the first line of the output.
This PR fixes two issues with HTML generation that were introduced by a commit on March 31, 2016, "[count_ciphers is now un-sed'ed, minor improvements](a480e5f699)."
The first is that in `std_cipherlists()`, `[[ $DEBUG -ge 1 ]] && outln " -- $1" || outln` was changed to `[[ $DEBUG -ge 1 ]] && outln " -- $1" || outln`. The result being that in the HTML output, all of the tests from `run_std_cipherlists()` appear on the same line. This PR changes the line to:
```
[[ $DEBUG -ge 1 ]] && tm_out " -- $1"
outln
``
so that the line break is added to the HTML output, but the debugging information is not.
The second problem is that the commit on March 31 moved the call in main to `html_header()` until after the calls to `get_install_dir()`, `find_openssl_binary()`, `mybanner()`, `check4openssl_oldfarts()`, and `check_bsd_mount()`. The problem is that each of these functions may call an output function that will call `html_out()`.
If `html_out()` is called before `html_header()` and the command line contains `--htmlfile <htmlfile>`, then "htmlfile" will be written to before `html_header()` is called and then `html_header()` will warn that "htmlfile" already exists and then exit the program.
If `html_out()` is called before `html_header()` and the command line contains `--html`, then anything send to `html_out()` before `html_header()` is called (such as the banner) will not appear in the HTML file.
