Rework of util::which

The new version deals now correctly with absolute paths,

where just the extensions are added, and it is checked

whether the program is executable.

Extended regression test to deal with optional and required

external dependencies. Missing optional external programs

produce warnings.

Reduced redundancy

call text_templates::create_pdf_from_html from

text_templates::create_pdf_content instead of replicating logic

removed code, which was commented out since ages.

Cleanup of external binaries: always use "util::which" to resolve binaries

deprecate unused command cr_check_orphaned_files

reduced number of external dependencies

fixed typo

Improved consistency with external programs

Since "unzip" is used as well on various other places,

use it as well in the file storage. This means that

the parameter "UnzipBinary" for the file-storage package

is now obsolete.

Cleanup of external binaries: always use "util::which" to resolve binaries

Background: it is important to always use the same binaries of some

programs. This is important for security reasons, consistency, and

configurability (some operating systems have read-only file systems,

which might be on the path and should be avoided for some operations).

Use GNU grep when available

GNU grep is now used for the lookup of message keys using the

"--include=" parameter. This improves the speed of the command

significantly and reduces the number of external dependencies (no

"find", or "xargs" needed).

Removed obsolete files www/admin/lookups-include.tcl

The file www/admin/lookups-include.tcl was replaced some time ago by

www/admin/message-usage-include.tcl but as it looks, not removed from

the repository.

Furthermore, this change makes the handling of "identify" consistent

with "convert". Before, the parameter "ImageMagickIdentifyBinary"

could not be modified via the parameter settings, only

"ImageMagickConvertBinary" was defined.

Bump version number to 5.10.1b3 to pick up additional parameter.

Improve test:

whether the html filter will accept or not a script tag is configuration-dependent. We now enforce that the outcome is consistent with the security check for HTML used in the filter itself.

Fix method signature

Flush the whole key pattern, now that the key can end either in true or false

Fixes locale__test_lang_conn_browser_locale automated test

Manually replace the ":" entity to prevent attempts at disguising "javascript:" links

Replicate injection attempt by penetration tools

Fixed unreviewed commit, which might lead to hard-to-spot errors

The last change assumed that "nls_language" can be hard-wired to

contain most 5 characters. While this not backed by the OpenACS data

model, the standard (RFC 5646) explicitly states that there is no

upper limit on the size of language tags. The tree letter language

codes have been standard since 2001 (RFC 4646).

The change accepts now all defined locales. When the specified locale

is not enabled, it provides a log notice, when the locale is not

defined at all, it provides a warning and falls back to "en_US".

page filters with NUL value

Prefer "string first" over "regexp" since this is twice as fast.

Fixed implementation of value checker dbtext

The old version was not persistent in the blueprints.

Furthermore, the new version is more than 2x faster by

avoiding regular expressions.

bootstrap5 theme: prettify appearance for "ad_form -mode display"

The previous change was already a big improvement. The change makes

it easier to distinguish the field labels from the field content.

security::validated_host_header: Made acceptance of configured vhosts the first check

Under certain conditions (such as running in a container, or reverse

proxy situations) the admin of a server wants to specify accepted host

names. This can be achieved in the "*/servers" section of a network

driver. These values are used now first for accepting host header

fields. This change avoids unexpected redirects to, e.g., internal

server addresses.

bugfix: fixed test test_ad_register_proc when running in a container

When runnig in a container, one cannot use util_current_localtion, which refers

to the URL to reach the server from the container host. To address the server

inside the container, acs::test::url should be used.

This change does not matter for non-containerized applications

Provide facilities to validate against invalid SQL strings

We introduce a new page contract filter and nsf validator called "dbtext". They implement enforcing of a value to be useable in an SQL query. Currently, this means that the value should not contain the NUL character, but the definition may change in the future or become database-specific.

The html contract filter has also be extended to reject the NUL character.

The test suite has been updated/extended to reflect the changes.

Separate form widgets from label and help-text vertically by wrapping them in a div, render form labels in a larger font for better visibility
