# Comment System
The current comment system (2023-02-24) was written from scratch by HPR
volunteers. It replaced a proprietary (and rather unsatisfactory) system.
It has been in use since 2017, has proved reliable and has needed very
little maintenance.
## Overview
There are three main components of the system:
1. A database table called `comments` which holds each comment with its
metadata.
2. PHP code which takes in each comment from the comment form (available on
every show page) and converts it to a JSON format which is available to
authorised people on the website and is emailed to the `admin` list and to
`comments@hackerpublicradio.org`.
3. The scripts stored in the `Comment_system` directory on the Gitea repo.
These are capable of decoding the email or or taking the JSON files and
offering them for approval. If approved the comment is added to the
database, otherwise it is not added. The incoming file is stored for future
access if needed. The scripts communicate the decision to the PHP code on
the server and the intermediate files are cleaned up there.
## Database
The `comments` table has the following structure:
```
+---------------------+----------+------+-----+---------------------+----------------+
| Field | Type | Null | Key | Default | Extra |
+---------------------+----------+------+-----+---------------------+----------------+
| id | int(5) | NO | PRI | NULL | auto_increment |
| eps_id | int(5) | NO | MUL | NULL | |
| comment_timestamp | datetime | NO | | NULL | |
| comment_author_name | text | YES | | NULL | |
| comment_title | text | YES | | NULL | |
| comment_text | text | YES | | NULL | |
| last_changed | datetime | NO | | current_timestamp() | |
+---------------------+----------+------+-----+---------------------+----------------+
```
- `id` is an incrementing primary key
- `eps_id` is the primary key (show number) of the `eps` table to which the comment is linked
- `comment_timestamp` contains the time that the comment was submitted
- `comment_author_name` holds the name of the comment author as submitted (there are no checks against know hosts)
- `comment_title` holds the title submitted by the comment author
- `comment_text` contains the body of the comment
- `last_changed` contains the timestamp of the last change made to the comment (this is managed by a trigger called `before_comments_update`)
**Note** It's possible to edit a comment in the database. There is a command-line tool under the [Database](Database) directory which enables this,
using Vim as the editor. It's not documented at the moment.
## Server code
TBA
## Local processing
The management of comments was designed to be a local command-line process using a Perl script. A connection with the HPR database is needed and this
is achieved using an SSH tunnel. The `Pdmenu` menu system is used used to streamline things, but that's just a personal preference (though the
`.pdmenurc` menu definition file can be made available if required).
### Modes of working
There are two modes of working:
- An email is sent to `comments@hackerpublicradio.org` (a limited distribution address list). The email contains a JSON attachment with the comment
details.
- A copy of the JSON attachment file is stored in the directory `~hpr/comments` on the main server.
A single script called `process_comments` can handle the two modes. It expects two spool areas, one for email messages and the other for JSON files.
Email messages are written to the spool area (`CommentDrop`) by the Thunderbird MUA which has the ability to make message copies using a plugin. (More
details to follow.)
```
/home/cendjm/HPR/CommentDrop/
├── banned
├── processed
└── rejected
```
The sub-directories are where `process_comments` places the messages after processing (explained later).
JSON files are copied from the `comments` directory on the server into the JSON spool area (imaginatively) called `json`:
```
json
├── banned
├── processed
└── rejected
```
The sub-directories are used for the same purpose as in `CommentDrop` (explained later).
The JSON mode is only used when there are mail problems. The files are collected using `Pdmenu` which uses `scp` to achieve this.
**NOTE** These spool directory locations are "baked into" the `process_comments` script and should be in a configuration file.
### The `process_comments` script
This a Perl script which contains internal documentation (in POD format). Information about how to run the script can be obtained with the `-help`
option, or the full documentation can be viewed with the option `-doc`. A copy of the internal documentation is available in manual page format by
following [this documentation link](process_comments).
TBA
**NOTE** The script documentation is in need of updates.
### Screenshots
- Image 1:
- Running `process_comments` with three comments in the mail spool area. This example uses the `-verbose` option so a report of what messages have
been found is produced. The files have strange names generated from the mail subject, courtesy of the Thunderbird plugin.
- The first comment is offered for approval using a template to display the contents of the JSON attachment
- The options are `approve`, `ban`, `reject` and `ignore`. In this case choice `a` is selected to approve this comment.
![Image 1](images/process_comments_1.png)
- Image 2:
- All three comments have been processed, with each one being approved. The script actions the choices at the end.
- The (`-verbose`) output lists the comments being added to the database (attached to the relevant shows).
- Each mail message is moved to the `processed` sub-directory.
- The script communicates with the server requesting the deletion of the original JSON files, and the success return (`200/OK`) shows that this
has been completed.

# Community News
## Overview
This directory contains various tools for managing the Community News shows:
- reserving Community News slots ahead of time
- making email to announce the upcoming Community News show recording
- managing the iCal calendar with Community News reservations in it
- making the show notes for the Community News shows (used for the recording and saved in the database)
## Functions
### Reserving Community News slots
The script used is called `reserve_cnews` and is capable of reserving a number of shows from a given date.
A copy of the internal documentation for this script (available through the `-help` option) is available in manual page format by following [this
documentation link](reserve_cnews).
#### Usage summary
```
$HOME/HPR/Community_News/reserve_cnews -config=$HOME/HPR/.hpr_livedb.cfg -from -count=1
```
The script is normally run with the live database configuration file, so the tunnel to the server must be open. The `-from` option can be used without
the date part which causes the script to find the reservation with the latest date and add more reservations beyond it. It is advised to use
`-count=1` because the default behaviour is to add 12 reservations which may be excessive.
At the time of writing (2023-04-10) 12 reservations are maintained, with one being added each month. This is done to help ensure hosts posting shows
into the future are less likely to clash with the first Monday of each month.
### Announcing the next Community News show
This function is managed by the script called `make_email`.
This script was written in 2013 with the intention that it would send out email to the *HPR* mailing list. This functionality was never implemented,
though it could probably be made to work now. The script has always been used to write the email to a file which is then copied into a message in an
email client and sent to this list.
A copy of the internal documentation for this script (available through the `-documentation` option) is available in manual page format by following
[this documentation link](make_email).
#### Usage summary
```
> $HOME/HPR/Community_News/mailer.testfile # Empty the default file
$HOME/HPR/Community_News/make_email -dbconf=$HOME/HPR/.hpr_livedb.cfg
xclip -i $HOME/HPR/Community_News/mailer.testfile
```
The first line empties the file `mailer.testfile` in the working directory (where the script exists). The `make_email` script is then run with the
live database configuration file (so the tunnel must be open) and every other option left in its default state. The `xclip` command can be used to
place the file in the clipboard so it can be pasted into the email.
### Refreshing the iCal calendar
TBA
### Community News show notes
The notes for the Community News shows released every month are built with a script, a `TT²` template and various files for inclusion.
#### `make_shownotes`
This is the main script and is written in Perl. It accesses the MySQL/MariaDB database to gather show, host and comment information. It writes the
notes for the selected show to the database. It needs the SSH tunnel to be set up before being run and to use this it requires the configuration file
set up for this purpose.
It's possible to select the required template but the default name used by the script is `shownote_template.tpl`. For convenience this is a symbolic
link to another file, and at the moment the target file is `shownote_template11.tpl`. Thus allowing the script to default the template name means the
latest version is used. This template generates HTML and embeds some CSS definitions that affect the layout of the notes.
TBA
A copy of the internal documentation for this script is available in manual page format by following [this documentation link](make_shownotes).
**NOTE** The script documentation is in need of updates.

# FAQ
## Overview
This is a test document implementing the idea of a list of questions and answers of the sort often encountered on HPR. The idea was to place them in a
searchable document (perhaps using CSS to allow the answers to revealed on demand). The reasoning was that finding answers to questions was often
difficult; this page would provide links to the definitive answers, each with some sort of preamble.
A draft document was produced in 2021 but the idea was not seen as desirable. The work undertaken to produce this document was retained in case it
ever became of interest in the future.

It's not clear whether an equivalent exists elsewhere.
- [InternetArchive](Internet-Archive):
- Tools for uploading HPR shows to the Internet Archive (IA).
- Link_Checker:
- Rudiments of a project to scan HPR shows looking for links which have
vanished. The intention was to identify these and attempt to find the
latest copies on the *Wayback Machine* and replace the faulty URLs with
links to the saved copies.
- PostgreSQL_Database:
- Work was done to design and build an alternative database to the
MySQL/MariaDB version incorporating improvements to the database design
(one-to-many and many-to-many linkages for hosts and shows, tags and
shows, etc), and to make use of the advanced features offered by
PostgreSQL.
- Abandoned because of:
- Problems finding a hosting site for this database system
- Concern that maintenance of a complex database like the one
envisaged would be difficult given the lack of DBA experience
amongst the volunteers.
- Show_Submission:
- Tools for processing new shows arriving via the submission form.
- Brief overview:
- Shows arrive from the form as JSON data, audio file(s) and assets of
various sorts
- The note formats accepted are many, form plain text, through various
markup formats to HTML5.
- The tools here assist with the processing of the notes by making a
local copy of the JSON data and any assets (not usually the audio).
The notes are assembled locally and the end product - an HTML
fragment for addition to the database, and any assets like pictures
and scripts, are sent to the server.
- The final stages of audio preparation and posting of the complete
show are performed elsewhere.

# How To Do Stuff
This is the TLDR part of the documentation
## Upload future shows to the IA
This task uses `future_upload`. It is best run in the morning in the UK/Europe
time zones since the IA servers are based on the west coast of the USA and it
will be the early hours of the morning there.
Sometimes the servers can be overloaded and attempts to upload will be met
with error messages and the uploader will retry. It is possible to check
whether an overload is likely by running the `ia` command, and this will be
added later.
Run the command:
```
./future_upload -d0
```
A lot of output will be generated because `make_metadata` is run in `verbose`
mode, and the `ia` command run to perform the uploads is naturally quite
verbose.
This script is documented elsewhere, but in brief, it does the following:
- Looks for all audio files in the holding area (`/data/IA/uploads`). These
will be called `hprDDDD.type` where `DDDD` is a four-digit number, and
`type` is an audio type such as `mp3` and `ogg`.
- Any shows found this way are checked to see if they are on the IA, and if
not they are queued for processing.
- Once the holding area has been scanned the queued shows are uploaded:
- Metadata is generated in the form of a CSV file by `make_metadata` with
instructions for uploading the show notes and audio files.
- A Bash script file is generated by `make_metadata` which contains
commands to upload non-audio files - if there are any.
- The CSV is fed to the `ia upload` command.
- The Bash script (if any) is run.
- It can take a few minutes to possibly hours for the shows to be fully loaded
and accessible on `archive.org`.
## Check the status of an upload
Once the upload has finished as far as the various scripts (like
`future_upload`) are concerned the IA software takes over on the various
servers. If you have the required authorisation (being an administrator of the
`HackerPublicRadio` collection) then it's possible to use the web page for a
given show to determine if all the IA tasks are complete.
Here is an example of what can be seen when the `History` link is activated:
![History for show hpr1462](images/IA_history_hpr1462.png)
## Refresh the show notes on the IA
If the notes in the database are changed on the HPR server it's necessary to
propagate the changes to the IA. At present this is done the *hard way* by
running `make_metadata` and then running `ia`.
When running `make_metadata` the mode chosen is just to generate the metadata
without downloading files for upload. The example below shows this being done
to correct the notes for show 3523. Note that the CSV file created is called
`metadata_3523.csv`.
The `ia` command just updates the IA metadata. It uses the bulk mode and reads
the CSV file created above, specified with `--spreadsheet` option.
What the warning messages returned by `ia` mean is unknown. These are not
always shown and the process always seems to work quite reliably.
```
$ ./make_metadata -from=3523 -out -meta -noassets
Output file: metadata_3523.csv
$ ia metadata --spreadsheet=metadata_3523.csv
hpr3523 - success: https://catalogd.archive.org/log/3114823140
hpr3523 - warning (400): no changes to _meta.xml
hpr3523 - warning (400): no changes to _meta.xml
hpr3523 - warning (400): no changes to _meta.xml
hpr3523 - warning (400): no changes to _meta.xml
hpr3523 - warning (400): no changes to _meta.xml
```
The `-noassets` option is important in case the item in question contains
*assets* - supplementary files such as photographs and examples. Without this
`make_metadata` will download any assets that there may be.
The `-out` option causes output to be written to a file where the name if
generated by the script. The `-meta` option means *metadata only* since we are
only changing metadata here.
To update multiple shows do as the following example which adds missing notes
to shows 3555 and 3568 (added on 2022-04-18):
```
$ ./make_metadata -list=3555,3568 -out -meta -noassets
Output file: metadata_3555-3568.csv
$ metadata=metadata_3555-3568.csv
$ ia metadata --spreadsheet=$metadata
hpr3555 - success: https://catalogd.archive.org/log/3231074147
hpr3568 - success: https://catalogd.archive.org/log/3231074213
```
## Delete a show from the IA
This occurs when a show needs to be removed from the HPR system and the IA.
Examples in the past have been:
- failure to get approval from a person or organisation to release the
content - perhaps delayed realisation that this is needed.
- show content that generates complaints or which might be legally dubious or
outright illegal.
The process described here is not true deletion, since when an IA identifier
(show in our case) has been created it cannot be deleted - except by IA
Administrators, who are usually very reluctant to do it.
What is done to the IA item is that it has all files removed and all of the
metadata is either removed or replaced by `Reserved`.
A script has been written to assist with this called `delete_ia_item` which
takes the episode identifier as an argument. By default it runs in *dry-run*
mode where no changes are made. The script checks that the item actually
exists on the IA, then it either reports what commands it will run (in
*dry-run* mode) or it performs the commands.
As of 2022-05-09 the live mode does not actually perform the commands, it
simply echoes them. This is because the script has not yet been fully tested
in a live situation. Once that has been done the commands will be made active.
The commands issued use the `ia` tool described elsewhere in the Wiki. It uses
`ia delete` to remove all the files then calls `ia metadata` a number of times
to change or remove metadata fields. In some cases the removal needs to know
what values to remove, so `ia metadata` is used to write all of the metadata
to a temporary file and the `jq` tool is used to parse out the required
values.
### TBA
- There is a way of hiding items on the IA, which it seems that an
administrator of a collection can implement. Not clear about this but it
warrants investigation.
## Deal with shows that are in the wrong collection
When a show is uploaded to the IA it should be assigned to the collection
called `'hackerpublicradio'`. Very rarely, it will be assigned to the default
collections: `'Community Audio'` and `'Community Collections'`, possibly
because the metadata (which specifies the collection) is faulty or isn't read
properly. This error has been quite rare over the history of uploading shows.
It was discovered on 2022-06-15 that show 2234 was in the wrong collections.
Tests were performed to see if any other shows had been wrongly assigned
without being noticed.
In case it ever happens again, here are the steps which were performed:
1. All of the identifiers in the `'hackerpublicradio'` collection were
downloaded with the command:\
`ia search "collection:hackerpublicradio" -f identifier -s 'identifier asc' > hackerpublicradio_collection.json`
1. This generates a file with JSON objects that look like:\
`{"identifier": "hpr3630"}`\
The list also contains the batches of shows uploaded before 2014.
1. An AWK script was written to find any gaps. The script is called
`check_IA_identifiers.awk`. See below for the script and how it was run.
1. The script was run against the JSON file, which had been filtered with `jq`
and it showed that the only missing show was 2243.
### AWK script `check_IA_identifiers.awk`
```awk
# check_IA_identifiers.awk, Dave Morriss, 2022-06-15
#
# Collect all 'hprxxxx' show identifiers into a hash

### Running the script `check_IA_identifiers.awk`
The way to run this is as follows:
```
$ awk -f check_IA_identifiers.awk < <(jq -r .identifier hackerpublicradio_collection.json | grep -E 'hpr[0-9]{4}')
>> hpr2243
```
The `jq` filter (in raw mode `-r`) outputs the value of the `identifier` key.
The `grep` excludes the older IA items uploaded before 2014.
The only show found was `hpr2243`.
### Correcting the collection(s) for a show
This can only be done by the IA staff. Send an email to `info@archive.org`
reporting the item and explaining the issue. The item should be in the
collections 'Hacker Public Radio' and 'Podcasts'.

# Internet Archive Workflow
## Overview
This section describes the processes used to upload Hacker Public Radio
episodes to the Internet Archive (`archive.org`).
**Note**: This text is taken from the Wiki built under GitLab several years
ago. It's in the process of being updated for the current practices developed
since then.
## History
We have been adding HPR shows to the Internet Archive since 2010 when shows
1-620 were uploaded as MP3 audio in blocks of 10.
There was a delay of four years before the current project began in 2014.
Since then shows have been uploaded individually, with show notes. The normal
cycle has been to upload the previous weeks' shows each weekend, and gradually
work through the older shows going back in time.
Originally in the current project, all that was uploaded was the WAV format
audio and the show notes. The WAV file was transcoded to other formats by the
Internet Archive software.
Towards the end of 2017 auxiliary files were uploaded for shows that have
them: files like pictures, examples, supplementary notes and so forth. Also,
in December 2017 we started pointing our feeds at the Internet Archive instead
of the HPR server, and, since the audio files transcoded on the Internet
Archive machines do not include audio tags, we began generating all the
formats ourselves, with tags, and uploaded them too. We also needed to upload
shows for the week ahead rather than the week just gone.
## Workflow
**Obsolete, needs work**
1. As part of the process of preparing a new show the audio is transcoded to a
variety of formats. The formats are: *flac*, *mp3*, *ogg*, *opus*, *spx*
and *wav*.
2. The audio files are copied to the Raspberry Pi `borg` in Ken's house from
the HPR server, and named `hpr<show>.<format>` as appropriate for the show
number and audio format (e.g. `hpr2481.wav`). They are stored in the
directory `/var/IA/uploads/`.
3. The upload process itself, uses the
[*internetarchive*](https://internetarchive.readthedocs.io/en/latest/installation.html)
tool. This provides the
[`ia`](https://internetarchive.readthedocs.io/en/latest/cli.html) command.
There is a bulk mode which the `ia` command offers, and this is what is
used. This takes a *comma separated variable* (CSV) file, which is
generated by an HPR tool called `make_metadata` which is currently run
under the account `perloid`.
4. The shows to be uploaded are checked for HTML errors. A script called
`clean_notes` is used which uses a Perl module called `HTML::Tidy` to check
for errors. Errors are corrected manually at this point. (TODO: explain in
more detail)
5. The `make_metadata` script generates data for a block of shows. It collects
any associated files and saves them in the `/var/IA/uploads/` directory. It
generates a CSV file which points to the various audio formats for each
show, as well as any associated files. Further details of what this tool
can do are provided in its [documentation](make_metadata).
6. During metadata creation the `make_metadata` script will halt if it finds
that a given show does not have a summary (extremely rare for new shows) or
tags (sadly fairly common). It is possible to override this step, but it is
preferable to supply the missing elements because they are of great use on
`archive.org`.
7. Having created the metadata in a CSV file this is processed with the `ia`
tool. This is run in *bulk upload* mode, it reads the CSV file and creates
an item on archive.org. It uploads any audio files listed in the CSV file
as well as any associated files. (TODO: add an example)
8. Once all uploads have completed the script
[`delete_uploaded`](delete_uploaded) is run to delete files in
`/var/IA/uploads` which have been uploaded. The VPS does not have much disk
space so deleting unnecessary files is important.
*To be continued*

# InternetArchive
## Overview
We upload all HPR shows to the Internet Archive (referred to as the *IA* here).
Each show is an IA *item* with an URL such as: `https://archive.org/details/hpr0144`. Here the number `0144` is the show number using 4 digits with
leading zeroes.
A show consists of a front page built from the HTML copied from the HPR database. Attached to the item are all the files associated with the show;
always the audio files and any other *assets* such as photographs, added text, scripts, etc. The intention is to make the copy of the show on the IA
stand-alone. For historical reasons, there were some shows where not all associated files had been uploaded. However, a project which ended in
December 2022 uploaded all of the missing assets.
In 2023 text transcripts of the audio of hpr shows are being generated. All of the older shows had their transcripts generated and placed on the HPR
server. At the time of writing (2023-02-26) the uploading of the transcripts to the IA has not taken place. New show transcripts are being added to IA
items, but this is not the case for the backlog of old shows.

## Overview
We upload all HPR shows to the Internet Archive (referred to as the *IA*
here).
Each show is an IA *item* with an URL such as:
`https://archive.org/details/hpr0144`. Here the number `0144` is the show

A show consists of a front page built from the HTML copied from the HPR

always the audio files and any other *assets* such as photographs, added text,
scripts, etc. The intention is to make the copy of the show on the IA
stand-alone. For historical reasons, there are some shows where not all
associated files have yet been uploaded. There should be a record of these,
but nothing has yet been done to add missing files.
### Status
- At the time of writing, 2022-03-05, most of the older shows in the range
1-870 have been uploaded (in reverse numerical order) but the last three
(1-3) have not, due to a naming clash.
- Update 2022-08-04: the naming clash mentioned above was cleared and all
shows have now been uploaded. The project to re-upload certain shows is
ongoing. This will ensure all *assets* are on the IA and that any metadata
is up to date.
## History
We have been adding HPR shows to the Internet Archive since 2010 when shows
1-620 were uploaded as MP3 audio in batches of 10. For example, the audio for
shows 121-130 exist as the batch:
<https://archive.org/details/Hackerpublicradio.org-archiveEp0121-Ep0130>
There was a delay of four years before the current project began in 2014.
Since then shows have been uploaded individually, with show notes. The original
cycle was to upload the previous weeks' shows each weekend, and gradually
work through the older shows going back in time.
The main tools used are [`make_metadata`](make_metadata) (a locally-developed
Perl script) and `ia` (a Python script created by IA programmers).
Originally in the current project, all that was uploaded was the WAV format
audio and the show notes. The WAV file was transcoded to other formats by the
Internet Archive software.
Towards the end of 2017 auxiliary files were uploaded for shows that have
them: files like pictures, examples, supplementary notes and so forth. Also,
in December 2017 we started pointing our RSS feeds at the Internet Archive instead
of the HPR server, and, since the audio files transcoded on the Internet
Archive machines do not include audio tags, we began generating all the
formats ourselves, with tags, and uploaded them too. We also needed to upload
shows for the week ahead rather than the week just gone. A script called
`weekly_upload` performed the necessary steps top preload shows. This is not
currently used.
In early 2021 the upload strategy was changed. A script called
[`future_upload`](future_upload) was written which determines if there are
shows to upload from the cacheing area on `borg`. It does this by consulting a
history file and by querying the IA itself. If shows are found they are
uploaded.
At around the same time, a script called [`past_upload`](past_upload) was
written to upload shows in the range 1-870. This collects the show audio from
the HPR server - which is just MP3 format - transcodes it into all of the
formats required on the IA, and uploads the results. This is run on a regular
basis from `borg`, processing five shows a day so as not to overload the IA
servers.
A SQLite database exists (called `ia.db`) which is used to hold information
about shows uploaded to the IA. This is useful to keep track of what has been
done, it is used when generating the monthly Community News show notes, and is
intended to be incorporated into the planned new HPR database design.
## Software and other components
This is an alphabetic list of scripts, for reference:
### archive_metadata
This Bash script adds metadata files (produced by `make_metadata` - see below)
to a compressed `tar` file (called `meta.tar.bz2`) and deletes the originals.
There is currently no mechanism for purging the oldest files stored in this
way.
### check_week
This Bash script is used to check what shows exist in the HPR database for a
particular week (by week number) and whether these shows have been uploaded to
the IA. It was created to prevent gaps from appearing in the sequence of shows
on the IA, caused by too infrequent runs of `future_upload`.
Documentation may be found [here](check_week).
### collect_show_data
This Bash script is used to collect data from the IA in JSON format for adding
to the SQLite database (`ia.db`). This is being done on a local workstation
rather than on `borg`, but the database is being kept on Gitea and a copy
stored on `borg:~perloid/InternetArchive/ia.db` which is synchronised daily.
### future_upload
This Bash script runs on `borg` where it performs show uploads by looking at
the cache of show files (`/var/IA/uploads`) and determining which have not yet
been uploaded to the IA. Since the checks interrogate the IA and are
expensive, the script maintains a history file in `.future_upload.dat` which
lists the shows that have been uploaded.
Documentation may be found [here](future_upload).
### make_metadata
This Perl script generates CSV metadata for driving the upload of HPR shows to
the Internet Archive. The script is mainly called from other scripts, because
its use is rather complex. The script itself contains its own documentation, a
copy of which is included [here](make_metadata).
### past_upload
A Bash script for uploading older shows to the IA on `borg`. Downloads the
audio (always `mp3` for older shows) and transcodes it to the formats used for
newer shows, maintaining id3 tags and so forth along the way. Generates CSV
metadata with `make_metadata` and uploads the shows with the `ia` tool.
Documentation may be found [here](past_upload).
## Dependencies
Aside from Perl modules (which are documented in the relevant POD sections in
the scripts), the various Bash scripts perform checks on pre-requisite files
and tools.
This is a list of these pre-requisites, starting with Bash and Perl scripts:
### ~/bin/close_tunnel
A Bash script to close down the SSH tunnel opened by `open_tunnel`
### ~/bin/function_lib.sh
A file of shared Bash functions.
### ~/bin/open_tunnel
A Bash script used to open an SSH tunnel to the HPR server so that scripts can
easily access the MariaDB database there.
### ~/bin/transfer_tags
A Perl script which transfers `id3` tags from a main file to a number of
subsidiary files.
### ~/bin/tunnel_is_open
A Bash script that tests whether the SSH tunnel is open.
### ia
A Python script from the Internet Archive used to interact with the IA
servers. This is used to interrogate the state of the collection on the IA and
to upload files.
The tool can be installed as described here: [installing
*internetarchive*](https://archive.org/services/docs/api/internetarchive/installation.html)
This provides the `ia` command.
### jq
The JSON parser used to manipulate JSON files imported from the IA.

## `future_upload`
### Description
This is a Bash script which uploads **all** shows which have not yet been
uploaded. It is not possible to skip any shows which are in the pending state.
It is possible to limit the number of shows uploaded in a run however - see
below.
The script can be found on `borg` at `~perloid/InternetArchive`. It examines
the directory `/data/IA/uploads`. It scans all the files it finds there which
conform to the (POSIX extended) regular expression `'hpr[0-9]4.*'`. It uses
these to recognise shows (every time the file name changes from `hpraaaa.*` to
`hprbbbb.*` it performs checks on show `hpraaaa`).
The script determines whether the show is already on the IA. Shows on the IA
have names (identifiers in IA terms) which conform to the pattern
`hpr<number>`. Because these searches of the IA are expensive, only newly
discovered shows are checked in this way. If a show is already on the IA the
identifier is stored in a cache file called `.future_upload.dat`.
The assumption is made that any show not already on the IA is eligible for
upload. With the advent of show state information available through a CMS
query, it is now possible to ignore shows which do not have the status
`MEDIA_TRANSCODED`. This addition has not been made as yet (dated 2022-05-11).
The script collects a list of all shows ready for upload up to a limit of 20.
The IA servers can become saturated by requests that are over a certain size,
so we limit the number of shows per run to help with this. There is currently
no way to change this upper limit without editing the script, but it is
possible to request a lower limit with the `-l` option.
A check is made on each show eligible for uploading to ensure that all of the
expected files are available. All of the transcoded audio formats are looked
for, and if any are missing the script aborts.
Next the script runs `make_metadata` - if it is in live mode. In dry-run mode
it simply reports what would have happened. It determines the names of the
output files itself; it uses the same algorithm as `make_metadata` to ensure
the calling script uses the correct names.
Note: It may be desirable to add a means whereby `make_metadata` could return
the file names it uses in a future release.
Calling `make_metadata` will cause the generation of a CSV file and a Bash
script. It the run is successful the CSV "spreadsheet" is passed to the
command `ia upload --spreadsheet=<name>` and if this is successful the Bash
script (if any) will be run.
Any errors will result in the upload process being aborted.
If the uploads are successful the IA identities (shows) are written to the
cache file.
## Help output
This is what is output when the command `./future_upload -h` is run.
```
future_upload - version: 0.0.5
Usage: ./future_upload [-h] [-v] [-D] [-d {0|1}] [-r] [-l cp]
Uploads HPR shows to the Internet Archive that haven't yet been uploaded. This
is as an alternative to uploading the next 5 shows each week for the coming
week.
Options:
-h Print this help
-v Run in verbose mode where more information is reported
-D Run in debug mode where a lot more information is
reported
-d 0|1 Dry run: -d 1 (the default) runs the script in dry-run
mode where nothing is uploaded but the actions that
will be taken are reported; -d 0 turns off dry-run
mode and the actions will be carried out.
-r Run in 'remote' mode, using the live database over an
(already established) SSH tunnel. Default is to run
against the local database.
-l N Control the number of shows that can be uploaded at
once. The range is 1 to 20.
Notes:
1. When running on 'borg' the method used is to run in faux 'local' mode.
This means we have an open tunnel to the HPR server (mostly left open) and
the default file .hpr_db.cfg points to the live database via this tunnel.
So we do not use the -r option here. This is a bit of a hack! Sorry!

make_email [-help] [-documentation] [-debug=N] [-month=DATE] [-[no]mail]
[-from=FROM_ADDRESS] [-to=TO_ADDRESS] [-date=DATE] [-start=START_TIME]
[-end=END_TIME] [-config=FILE] [-dbconfig=FILE]
./make_email -dbconf=$HOME/HPR/.hpr_livedb.cfg -date=2022-12-27
# OPTIONS
- **-help**
Prints a brief help message describing the usage of the program, and then exits.
- **-documentation** **-man**
Prints the entire embedded documentation for the program, then exits.
Another way to see the full documentation use:
**perldoc ./make\_email**
- **-debug=N**
Enables debugging mode when N > 0 (zero is the default, no debugging output).
The levels are:
Values are:
1. Reports all of the settings taken from the configuration file, the provided
command line options or their default values. The report is generated early on
in the processing of these values. Use **-debug=2** for information about the
next stages.
2. Reports the following (as well as the data for level 1):
- .
Details of the start date chosen
- .
Details of the year, name of month, readable date, and recording start and end
times.
- .
The subject line chosen for the email.
- .
The date of the show being searched for in the database.
- .
The number of the show found in the database.
- **-month=DATE**
Defines the month for which the email will be generated using a date in that
month. Normally (without this option) the current month is chosen and the date
of recording computed with in it. The month specified here is provided as
a ISO8601 date such as 2014-03-08 (meaning March 2014) or 1-Jan-2017 (meaning
January 2017). Only the year and month parts are used but a valid day must be
present.
- **-\[no\]mail**
\*\* NOTE \*\* The sending of mail does not work at present, and **-nomail** should
always be used.
Causes mail to be sent (**-mail**) or not sent (**-nomail**). If the mail is
sent then it is sent via the local MTA (in the assumption that there is one).
If this option is omitted, the default is **-nomail**, in which case the
message is appended to the file **mailer.testfile** in the current directory.
- **-from=FROM\_ADDRESS**
\*\* NOTE \*\* The sending of mail does not work at present.
This option defines the address from which the message is to be sent. This
address is used in the message header; the message envelope will contain the
_real_ sender.
- **-to=TO\_ADDRESS**
\*\* NOTE \*\* The sending of mail does not work at present.
This option defines the address to which the message is to be sent.
- **-date=DATE**
This is an option provides a non-default date for the recording. Normally the
script computes the next scheduled date based on the algorithm "Saturday
before the first Monday of the next month" starting from the current date or
the start of the month given in the **-month=DATE** option. If for any reason
a different date is required then this may be specified via this option.
The recording date should be given as an ISO8601 date (such as 2014-03-08).
- **-start=START\_TIME**
The default start time is defined in the configuration file, but if it is
necessary to change it, this option can be used to do it. The **START\_TIME**
value must be a valid **HH:MM** time specification.
- **-end=END\_TIME**
The default end time is defined in the configuration file, but if it is
necessary to change it, this option can be used to do it. The **END\_TIME**
value must be a valid **HH:MM** time specification.
- **-config=FILE**
This option defines a configuration file other than the default
**.make\_email.cfg**. The file must be formatted as described below in the
section _CONFIGURATION AND ENVIRONMENT_.
- **-dbconfig=FILE**
This option defines a database configuration file other than the default
**.hpr\_db.cfg**. The file must be formatted as described below in the section
_CONFIGURATION AND ENVIRONMENT_.
The default file is configured to open a local copy of the HPR database. An
alternative is **.hpr\_livedb.cfg** which assumes an SSH tunnel to the live
database and attempts to connect to it. Use the script _open\_tunnel_ to open
the SSH tunnel.
# DESCRIPTION
Makes and sends(\*) an invitation email for the next Community News with times per
timezone. The message is structured by a Template Toolkit template, so its
content can be adjusted without changing this script.
In normal operation the script computes the date of the next recording using
the algorithm "Saturday before the first Monday of the next month" starting
from the current date or the start of the month (and year) given in the
**-month=DATE** option.
It uses the recording date (**-date=DATE** option) to access the MySQL database
to find the date on which the show will be released. It does that so the notes
on that show can be viewed by the volunteers recording the show. These notes
are expanded to be usable during the recording, with comments relating to
earlier shows being displayed in full, and any comments missed in the last
recording highlighted. Comments made to shows during the past month can be
seen as the shows are visited and discussed.
The email generated by the script is sent to the HPR mailing list, usually on
the Monday prior to the weekend of the recording.
Notes:
\* Mail sending does not work at present.
# DIAGNOSTICS
- **Unable to find ...**
The configuration file specified in **-config=FILE** (or the default file)
could not be found.
- **Use only one of -month=MONTH or -date=DATE**
These options are mutually exclusive. See their specifications earlier in this
document.
- **Missing start/end time(s)**
One or both of the start and end times is missing, either from the configuration file or
from the command line options.
- **Missing template file ...**
The template file specified in the configuration file could not be found.
- **Various database messages**
The program can generate warning messages from the database.
- **Invalid -date=DATE option '...'**
An invalid date has been supplied via this option.
- **Date is in the past '...'**
The date specified in **-date=DATE** is in the past.
- **Invalid -month=DATE option '...'**
An invalid date has been supplied via this option.
- **Date is in the past '...'**
The month specified in **-month=DATE** is in the past.
- **Various Template Toolkit messages**
The program can generate warning messages from the Template.
- **Couldn't send message: ...**
The email mesage has been constructed but could not be sent. See the error
returned by the mail subsystem for more information.
# CONFIGURATION AND ENVIRONMENT
## EMAIL CONFIGURATION
The program obtains the settings it requires for preparing the email from
a configuration file, which by default is called **.make\_email.cfg**. This file
needs to contain the following data:
<email>
server = MUMBLE_SERVER_NAME
port = MUMBLE_PORT
room = NAME_OF_ROOM
starttime = 18:00:00
endtime = 20:00:00
template = NAME_OF_TEMPLATE
</email>
## DATABASE CONFIGURATION
The program obtains the credentials it requires for connecting to the HPR
database by loading them from a configuration file. The default file is called
**.hpr\_db.cfg** and should contain the following data:
<database>
host = 127.0.0.1
port = PORT
name = DBNAME
user = USER
password = PASSWORD
</database>
The file **.hpr\_livedb.cfg** should be available to allow access to the
database over an SSH tunnel which has been previously opened.

&lt;a> or &lt;img> tag the _uri_ value is shown, as is any fragment and the related
link. The original file is reported here.
Each call of the function _find\_links\_in\_file_ is reported. On finding an
&lt;a> or &lt;img> tag the _uri_ value is shown, as is any fragment and the related
link. The original file is reported here, and if a link is to be ignored this
is reported.
- **-from=NUMBER**
This option defines the starting episode number of a group. It is mandatory to
provide either the **-from=NUMBER** option or the **-list=LIST** option (see
below).
- **-to=NUMBER**
This option specifies the final episode number of a group. If not given the
script generates metadata for the single episode indicated by **-from**.
The value given here must be greater than or equal to that given in the
**-from** option. The option must not be present with the **-count** option.
The difference between the episode numbers given by the **-from** and **-to**
options must not be greater than 20.
- **-count=NUMBER**
This option specifies the number of episodes to process (starting from the
episode number specified by the **-from**) option. The option must not be
present with the **-to** option.
The number of episodes specified must not be greater than 20.
- **-list=LIST**
This option is an alternative to **-from=NUMBER** and its associated modifying
options. The **LIST** is a comma-separated list of not necessarily consecutive
episode numbers, and must consist of at least one and no more than 20 numbers.
This option is useful for the case when non-sequential episode numbers are to
be uploaded, and is particularly useful when repairing elements of particular
episodes (such as adding summary fields and tags) where they have already
been uploaded.
For example, the following shows have no summary and/or tags, but the shows
are already in the IA. The missing items have been provided, so we wish to
update the HTML part of the upload:
$ ./make_metadata -list='2022,2027,2028,2029,2030,2033' -out -meta
Output file: metadata_2022-2033.csv
- **-output\[=FILE\]**
This option specifies the file to receive the generated CSV data. If omitted
the output is written to **metadata.csv** in the current directory.
The file name may contain one or two instances of the characters '%d', with
a leading width specification if desired (such as '%04d'). These will be
substituted by the **-from=NUMBER** and **-to=NUMBER** values or if
**-from=NUMBER** and **-count=NUMBER** are used, the second number will be the
appropriate endpoint (adding the count to the starting number). If neither of
the **-to=NUMBER** and **-count=NUMBER** options are used then there should only
be one instance of '%d' or the script will abort.
If no value is provided to **-output** then a suitable template will be
generated. It will be 'metadata\_%04d.csv' if one episode is being processed, and
'metadata\_%04d-%04d.csv' if a range has been specified.
Example:
./make_metadata -from=1430 -out=metadata_%04d.csv
the output file name will be **metadata\_1430.csv**. The same effect can be
achieved with:
./make_metadata -from=1430 -out=
or
./make_metadata -from=1430 -out
- **-script\[=FILE\]**
This option specifies the file to receive commands required to upload certain
files relating to a show. If omitted the commands are written to **script.sh**
in the current directory.
The file name may contain one or two instances of the characters '%d', with
a leading width specification if desired (such as '%04d'). These will be
substituted by the **-from=NUMBER** and **-to=NUMBER** values or if
**-from=NUMBER** and **-count=NUMBER** are used, the second number will be the
appropriate endpoint (adding the count to the starting number). If neither of
the **-to=NUMBER** and **-count=NUMBER** options are used then there should only
be one instance of '%d' or the script will abort.
If no value is provided to **-script** then a suitable template will be
generated. It will be 'script\_%04d.sh' if one episode is being processed, and
'script\_%04d-%04d.sh' if a range has been specified.
Example:
./make_metadata -from=1430 -script=script_%04d.sh
the output file name will be **script\_1430.sh**. The same effect can be
achieved with:
./make_metadata -from=1430 -script=
or
./make_metadata -from=1430 -script
- **-\[no\]fetch**
This option controls whether the script attempts to fetch the MP3 audio file
from the HPR website should there be no WAV file in the upload area. The
default setting is **-fetch**.
Normally the script is run as part of the workflow to upload the metadata and
audio to archive.org. The audio is expected to be a WAV file and to be in the
location referenced in the configuration file under the 'uploads' label.
However, not all of the WAV files exist for older shows.
When the WAV file is missing and **-fetch** is selected or defaulted, the
script will attempt to download the MP3 version of the audio and will store it
in the 'uploads' area for the upload script (**ias3upload.pl** or **ia**) to
send to archive.org. If the MP3 file is not found then the script will abort.
If **-fetch** is specified (or defaulted) as well as **-nometa\_only** (see
below) then the audio file fetching process will not be carried out. This is
because it makes no sense to fetch this file if it's not going to be
referenced in the metadata.
- **-\[no\]assets**
This option controls the downloading of any assets that may be associated with
a show. Assets are the files held on the HPR server which are referenced by
the show. Examples might be photographs, scripts, and supplementary notes.
Normally all such assets are collected and stored in the upload area and are
then sent to the archive via the script. The notes sent to the archive are
adjusted to refer to these notes on archive.org, making the HPR episode
completely self-contained.
- **-\[no\]meta\_only** (alias **-\[no\]noaudio**)
This option controls whether the output file will contain a reference to the
audio file(s) or only the metadata. The default is **-nometa\_only** meaning that
the file reference(s) and the metadata are present.
Omitting the file(s) allows the metadata to be regenerated, perhaps due to
edits and corrections in the database, and the changes to be propagated to
archive.org. If the file reference(s) exist(s) in the metadata file then the
file(s) must be available at the time the uploader is run.
Note that making changes this way is highly preferable to editing the entry on
archive.org using the web-based editor. This is because there is a problem
with the way HTML entities are treated and this can cause the HTML to be
corrupted.
- **-\[no\]silent**
The option enables (**-silent**) and disables (**-nosilent**) _silent mode_.
When enabled the script reports nothing on STDOUT. If the script cannot find
the audio files and downloads the MP3 version from the HPR site for upload to
archive.org then the downloads are reported on STDERR. This cannot be
disabled, though the STDERR output could be redirected to a file or to
/dev/null.
If **-silent** is specified with **-verbose** then the latter "wins".
The script runs with silent mode disabled by default. When **-nosilent** is
used with **-noverbose** the script reports the output file name and nothing
else.
- **-\[no\]verbose**
This option enables (**-verbose**) and disables (**-noverbose**)
_verbose mode_. When enabled the script reports the metadata it has collected
from the database before writing it to the output file. The data is reported
in a more readable mode than examining the CSV file, although another script
**show\_metadata** is also available to help with this.
If **-verbose** is specified with **-silent** then the former "wins".
The script runs with verbose mode disabled by default.
- **-\[no\]ignore\_missing**
The script checks each episode to ensure it has a summary and tags. If either
of these fields is missing then a warning message is printed for that episode
(unless **-silent** has been chosen), and if any episodes are lacking this
information the script aborts without producing metadata. If the option
**-ignore\_missing** is selected then the warnings are produced (dependent on
**-silent**) but the script runs to completion.
The default setting is **-noignore\_missing**; the script checks and aborts if
any summaries or tags are missing.
- **-\[no\]test**
DO NOT USE!
This option enables (**-test**) and disables (**-notest**)
_test mode_. When enabled the script generates metadata containing various
test values.
In test mode the following changes are made:
- .
The item names, which normally contain 'hprnnnn', built from the episode
number, have 'test\_' prepended to them.
- .
The collection, which is normally a list containing 'hackerpublicradio' and
'podcasts', is changed to 'test\_collection'. Items in this collection are
normally deleted by Archive.org after 30 days.
- .
The contributor, which is normally 'HackerPublicRadio' is changed to
'perlist'.
**NOTE** The test mode only works for the author!
- **-config=FILE**
This option allows an alternative script configuration file to be used. This
file defines various settings relating to the running of the script - things
like the place to look for the files to be uploaded. It is rare to need to use
any other file than the default since these are specific to the environmewnt
in which the script runs. However, this has been added at the same time as an
alternative database configuration option was added.
See the CONFIGURATION AND ENVIRONMENT section below for the file format.
If the option is omitted the default file is used: **.make\_metadata.cfg**
- **-dbconfig=FILE**
This option allows an alternative database configuration file to be used. This
file defines the location of the database, its port, its name and the username
and password to be used to access it. This feature was added to allow the
script to access alternative databases or the live database over an SSH
tunnel.
See the CONFIGURATION AND ENVIRONMENT section below for the file format.
If the option is omitted the default file is used: **.hpr\_db.cfg**
# DESCRIPTION
This script generates metadata suitable for uploading Hacker Public Radio
episodes to the Internet Archive (archive.org).
The metadata is in comma-separated variable (CSV) format suitable for
processing with an upload script. The original upload script was called
**ias3upload.pl**, and could be obtained from
_https://github.com/kngenie/ias3upload_. This script is no longer supported
and **make\_metadata** no longer generates output suitable for it (though it is
simple to make it compatible if necessary). The replacement script is called
**internetarchive** which is a Python tool which can also be run from the
command line. It can be found at _https://github.com/jjjake/internetarchive_.
The **make\_metadata** script generates CSV from the HPR database. It looks up
details for each episode selected by the options, and performs various
conversions and concatenations. The goal is to prepare items for the Internet
Archive with as much detail as the format can support.
The resulting CSV file contains a header line listing the field names required
by archive.org followed by as many CSV lines of episode data as requested (up
to a limit of 20).
Since the upload method uses the HTTP protocol with fields stored in headers,
there are restrictions on the way HTML can be formatted in the **Details**
field. The script converts newlines, which are not allowed into _&lt;br/_> tags
where necessary.
HPR shows often have associated files, such as pictures, examples, long-form
notes and so forth. The script finds these and downloads them to the cache
area where the audio is kept and writes the necessary lines to the CSV file to
ensure they are uploaded with the show. It modifies any HTML which links to
these files to link to the archive.org copies in order to make the complete
show self-contained.
# DIAGNOSTICS
- **Configuration file ... not found**
One or more of the configuration files has not been found.
- **Path ... not found**
The path specified in the **uploads** definition in the configuration file
**.make\_metadata.cfg** does not exist. Check the configuration file.
- **Configuration data missing**
While checking the configuration file(s) the script has detected that settings
are missing. Check the details specified below and provide the missing
elements.
- **Mis-match between @fields and %dispatch!**
An internal error in the script has been detected where the elements of the
@fields array do not match the keys of the %dispatch hash. This is probably the
result of a failed attempt to edit either of these components.
Correct the error and run the script again.
- **Invalid list; no elements**
There are no list elements in the **-list=LIST** option.
- **Invalid list; too many elements**
There are more than the allowed 20 elements in the list specified by the
**-list=LIST** option.
- **Failed to parse -list=...**
A list was specified that did not contain a CSV list of numbers.
- **Invalid starting episode number (...)**
The value used in the **-from** option must be greater than 0.
- **Do not combine -to and -count**
Using both the **-to** and **-count** is not permitted (and makes no sense).
- **Invalid range; ... is greater than ...**
The **-from** episode number must be less than or equal to the **-to** number.
- **Invalid range; range is too big (>20)**
The difference between the starting and ending episode number is greater than
20.
- **Invalid - too many '%d' sequences in '...'**
There were more than two '%d' sequences in the the name of the output file if
a range of episodes is being processed, or more than one if a single episode
has been specified.
- **Invalid - too few '%d' sequences in '...'**
There were fewer than two '%d' sequences in the the name of the output file
when a range of episodes was being processed.
- **Unable to open ... for output: ...**
The script was unable to open the requested output file.
- **Unable to find or download ...**
The script has not found a _.WAV_ file in the cache area so has attempted to
download the _MP3_ copy of the audio from the HPR website. This process has
failed.
- **Failed to find requested episode**
An episode number could not be found in the database. This error is not fatal.
- **Nothing to do**
After processing the range of episodes specified the script could not find
anything to do. This is most often caused by all of the episodes in the range
being invalid.
- **Aborted due to missing summaries and/or tags**
One or more of the shows being processed does not have a summary or tags. The
script has been told not to ignore this so has aborted before generating
metadata.
- **HTML::TreeBuilder failed to parse notes: ...**
The script failed to parse the HTML in the notes of one of the episodes. This
indicates a serious problem with these notes and is fatal since these notes
need to be corrected before the episode is uploaded to the Internet Archive.
- **HTML::TreeBuilder failed to process ...: ...**
While parsing the HTML in a related file the parse has failed. The file being
parsed is reported as well as the error that was encountered. This is likely
due to bad HTML.
- **Unable to open ... for writing: ...**
The script is attempting to open an HTML file which it has downloaded to
write back edited HTML, yet the open has failed. The filename is in the error
message as is the cause of the error.
# CONFIGURATION AND ENVIRONMENT
This script reads two configuration files in **Config::General** format
(similar to Apache configuration files) for the path to the files to be
uploaded and for credentials to access the HPR database. Two files are used
because the database configuration file is used by several other scripts.
The general configuration file is **.make\_metadata.cfg** (although this can be
overridden through the **-config=FILE** option) and contains the following
lines:
uploads = "<path to files>"
filetemplate = "hpr%04d.%s"
baseURL = "http://hackerpublicradio.org"
URLtemplate = "http://hackerpublicradio.org/local/%s"
IAURLtemplate = "http://archive.org/download/%s/%s"
The _uploads_ line defines where the WAV files are to be found (currently
_/var/IA/uploads_ on the VPS). The same area is used to store downloaded MP3
files and any supplementary files associated with the episode.
The _filetemplate_ line defines the format of an audio file such as
_hpr1234.wav_. This should not be changed.
The _baseURL_ line defines the common base for download URLs. It is used when
parsing and standardising URLs relating to files on the HPR server.
The _URLtemplate_ line defines the format of the URL required to download the
MP3 audio. This should not be changed except in the unlikely event that the
location of audio files on the server changes.
The _IAURLtemplate_ line defines the format of URLs on archive.org which is
used when generating new links in HTML notes or supplementary files.
The database configuration file is **.hpr\_db.cfg** (although this can be
overridden through the **-dbconfig=FILE** option).
The layout of the file should be as follows:
<database>
host = 127.0.0.1
port = PORT
name = DATABASE
user = USERNAME
password = PASSWORD
</database>

# NAME
make\_shownotes - Make HTML show notes for the Hacker Public Radio Community News show
# VERSION
This documentation refers to **make\_shownotes** version 0.1.3
# USAGE
make_shownotes [-help] [-doc] [-from=DATE] [-[no]comments]
[-[no]markcomments] [-[no]ctext] [-lastrecording=DATETIME]
[-[no]silent] [-out=FILE] [-episode=[N|auto]] [-[no]overwrite]
[-mailnotes[=FILE]] [-anyotherbusiness=FILE] [-template=FILE]
[-config=FILE] [-interlock=PASSWORD]
# OPTIONS
- **-help**
Displays a brief help message describing the usage of the program, and then exits.
- **-doc**
Displays the entirety of the documentation (using a pager), and then exits. To
generate a PDF version use:
pod2pdf make_shownotes --out=make_shownotes.pdf
- **-from=DATE**
This option is used to indicate the month for which the shownotes are to be
generated. The script is able to parse a variety of date formats, but it is
recommended that ISO8601 YYYY-MM-DD format be used (for example 2014-06-30).
The day part of the date is ignored and only the month and year parts are
used.
If this option is omitted the current month is used.
- **-\[no\]comments**
This option controls whether the comments pertaining to the selected month are
included in the output. If the option is omitted then no comments are included
(**-nocomments**).
- **-\[no\]markcomments** or **-\[no\]mc**
This option controls whether certain comments are marked in the HTML. The
default is **-nomarkcomments**. The option can be abbreviated to **-mc** and
**-nomc**.
The scenario is that we want to use the notes the script is generating while
making a Community News recording and we also want them to be the show notes
in the database once the show has been released.
Certain comments relating to shows earlier than this month were already
discussed last month because they were made before that show was recorded. We
don't want to read them again during this show, so a means of marking them is
needed.
The script determines the date of the last recording (or it can be specified
with the **-lastrecording=DATETIME** option, or its abbreviation
**-lr=DATETIME**) and passes it to the template. The template can then compare
this date with the dates of the relevant comments and take action to highlight
those we don't want to re-read. It is up to the template to do what is
necessary to highlight them.
The idea is that we will turn off the marking before the notes are released
\- they are just for use by the people recording the episode.
Another action is taken during the processing of comments when this option is
on. On some months of the year the recording is made during the month itself
because the first Monday of the next month is in the first few days of that
month. For example, in March 2019 the date of recording is the 30th, and the
show is released on April 1st. Between the recording and the release of the
show there is time during which more comments could be submitted.
Such comments should be in the notes for March (and these can be regenerated
to make sure this is so) but they will not have been read on the March
recording. The **make\_shownotes** script detects this problem and, if
**-markcomments** is set (and comments enabled) will show a list of any
eligible comments in a red highlighted box. This is so that the volunteers
recording the show can ensure they read comments that have slipped through
this loophole. The display shows the entire comment including the contents,
but disappears when the notes are refreshed with **-nomarkcomments** (the
default).
In this mode the preamble warning about comments to be ignored used to be
included, but now it is skipped if there are no such comments. This means one
switch can serve two purposes.
- **-lastrecording=DATETIME** or **-lr=DATETIME**
As mentioned for **-markcomments**, the date of the last recording can be
computed in the assumption that it's on the Saturday before the first Monday
of the month at 18:00. However, on rare occasions it may be necessary to
record on an earlier date and time, which cannot be computed. This value can
be defined with this option.
The format can be an ISO 8601 date followed by a 24-hour time, such as
'2020-01-25 18:00'. If the time is omitted it defaults to 18:00.
- **-\[no\]ctext**
This option controls whether the comment text itself is listed with comments.
This is controlled by the template, but the current default template only
shows the text in the **Past shows** section of the output. The default
state is **-noctext** in which the comment texts are not written.
- **-\[no\]silent**
This option controls whether the script reports details of its progress
to STDERR. If the option is omitted the report is generated (**-nosilent**).
The script reports: the month it is working on, the name of the output file
(if appropriate) and details of the process of writing notes to the database
(if the **-episode=\[N|auto\]** option is selected).
- **-mailnotes\[=FILE\]**
If desired, the show notes may include a section about recent discussions on
the HPR mailing list. Obviously, this text will change every month, so this
option provides a way in which an external file can be included in the show
notes.
The filename may be omitted which is a way in which a **BLOCK** directive can
be placed in the template and used rather than the file. The **BLOCK** must be
named **default\_mail** because this is the name the script uses in this
circumstance. See **shownote\_template8.tpl** for an example of its use.
The template must contain instructions to include the file or block. The file
name is stored in a variable '**includefile**' in the template. Directives of
the following form may be added to achive this:
[%- IF includefile.defined %]
Constant header, preamble, etc
[%- INCLUDE $includefile %]
Other constant text or tags
[%- END %]
The first directive causes the whole block to be ignored if there is no
**-mailnotes** option. The use of the **INCLUDE** directive means that the
included file may contain Template directives itself if desired.
See existing templates for examples of how this is done.
- **-anyotherbusiness=FILE** or **-aob=FILE**
If desired the shownotes may contain an 'Any other business' section. This is
implemented in a template thus:
[% IF aob == 1 -%]
<h2>Any other business</h2>
[% INCLUDE $aobfile -%]
[%- END %]
The template variable **aob** is set to 1 if a (valid) file has been provided,
and the name of the file is in **aobfile**.
The included file is assumed to be HTML.
- **-out=FILE**
This option defines an output file to receive the show notes. If the option is
omitted the notes are written to STDOUT, allowing them to be redirected if
required.
The output file name may contain the characters '**%s**'. This denotes the point
at which the year and month in the format **YYYY-MM** are inserted. For example
if the script is being run for July 2014 the option:
-out=shownotes_%s.html
will cause the generation of the file:
shownotes_2014-07.html
- **-episode=\[N|auto\]**
This option provides a means of specifying an episode number in the database to
receive the show notes.
It either takes a number, or it takes the string '**auto**' which makes the
script find the correct show number.
First the episode number has to have been reserved in the database. This is
done by running the script '**reserve\_cnews**'. This makes a reservation with
the title "HPR Community News for &lt;monthname> &lt;year>". Normally Community News
slots are reserved several months in advance.
Close to the date of the Community News show recording this script can be run
to write show notes to the database. For example:
./make_shownotes -from=1-Dec-2014 -out=/dev/null \
-comm -tem=shownote_template5.tpl -ep=auto
This will search for the episode with the title "HPR Community News for
December 2014" and will add notes if the field is empty. Note that it is
necessary to direct the output to /dev/null since the script needs to write
a copy of the notes to STDOUT or to a file. In this case we request comments
to be added to the notes, and we use the template file
**shownote\_template5.tpl** which generates an HTML snippet suitable for the
database.
The writing of the notes to the database will fail if the field is not empty.
See the **-overwrite** option for how to force the notes to be written.
If the **-episode=\[N|auto\]** option is omitted no attempt is made to write to
the database.
- **-\[no\]overwrite**
This option is only relevant in conjunction with the **-episode=\[N|auto\]**
option. If **-overwrite** is chosen the new show notes will overwrite any notes
already in the database. If **-nooverwrite** is selected, or the option is
omitted, no over writing will take place - it will only be possible to write
notes to the database if the field is empty.
- **-template=FILE**
This option defines the template used to generate the notes. The template is
written using the **Template** toolkit language.
If the option is omitted then the script uses the file
**shownote\_template.tpl** in the same directory as the script. If this file
does not exist then the script will exit with an error message.
For convenience **shownote\_template.tpl** is a soft link which points to the
file which is the current default. This allows the development of versions
without changing the usual way this script is run.
- **-config=FILE**
This option allows an alternative configuration file to be used. This file
defines the location of the database, its port, its name and the username and
password to be used to access it. This feature was added to allow the script
to access alternative databases or the live database over an SSH tunnel.
See the CONFIGURATION AND ENVIRONMENT section below for the file format.
If the option is omitted the default file is used: **.hpr\_db.cfg**
- **-interlock=PASSWORD**
This option was added to handle the case where the notes for a Community News
episode have been posted after the show was recorded, but, since the recording
date was not the last day of the month further comments could be added after
upload. Logically these comments belong in the previous month's shownotes, so
we'd need to add them retrospecively.
Up until the addition of this option the script would not allow the
regeneration of the notes. This option requires a password to enable the
feature, but the password is in a constant inside the script. This means that
it's difficult to run in this mode by accident, but not particulary difficult
if it's really needed.
Take care not to run in this mode if the notes have been edited after they
were generated!
# DESCRIPTION
## Overview
This script generates notes for the next Hacker Public Radio _Community News_
show. It does this by collecting various details of activity from the HPR
database and passing them to a template. The default template is called
**shownote\_template.tpl** and this generates HTML, but any suitable textual
format could be generated if required, by using a different template.
## Data Gathering
Four types of information are collected by the script:
- -
Details of new hosts who have released new shows in the selected month
- -
Details of shows which have been released in the selected month
- -
Details of topics on the mailing list in the past month can be included. This
is only done if the **-mailnotes=FILE** option is used. This option must
reference a file of HTML, which may contain Template directives if required.
- -
Comments which have been submitted to the HPR website in the selected month.
These need to be related to shows in the current period or in the past.
Comments made about shows which have not yet been released (but are visible on
the website) are not included even though they are made in the current month.
Comments are only gathered if the **-comments** option is selected.
## Report Generation
The four components listed above are formatted in the following way by the
default template.
- **New Hosts**
These are formatted as a list of links to the hostid with the host's name.
- **Shows**
These are formatted into an HTML table containing the show number, title and
host name. The show title is a link to the show page on the HPR website. The
host name is a link to the host page on the website.
- **Mailing list discussions**
If there have been significant topics on the mailing list in the month in
question then these can be summarised in this section. This is done by
preparing an external HTML file and referring to it with the
**-mailnotes=FILE** option. If this is done then the file is included into the
template.
See the explanation of the **-mailnotes** option for more details.
- **Comments**
These are formatted with &lt;article> tags separated by horizontal lines.
A &lt;header> shows the author name and title and a &lt;footer> displays a link to
the show and the show's host and the show title is also included. The body of
the article contains the comment text with line breaks.
## Variable, Field and Hash names
If you wish to write your own template refer to the following lists for the
names of items. Also refer to the default template **shownote\_template.tpl**
for the techniques used there. (Note that **shownote\_template.tpl** is a link
to the current default template, such as **shownote\_template8.tpl**).
The hash and field names available to the template are as follows
- **Global variables**
Variable Name Details
------------- -------
review_month The month name of the report date
review_year The year of the report date
comment_count The number of comments in total
past_count The number of comments on old shows
skip_comments Set when -comments is omitted
mark_comments Set when -markcomments is used
ctext Set when the comment bodies in the 'Past shows'
section are to be shown
last_recording The date the last recording was made
(computed if -markcomments is selected) in
Unixtime format
last_month The month prior to the month for which the notes are
being generated (computed if -markcomments is
selected) in 'YYYY-MM' format
- **New Hosts**
The name of the hash in the template is **hosts**. The hash might be empty if
there are no new hosts in the month. See the default template for how to
handle this.
Field Name Details
---------- -------
host Name of host
hostid Host id number
- **Show Details**
The name of the hash in the template is **shows**. Note that there are more
fields available than are used in the default template. Note also that certain
field names are aliases to avoid clashes (e.g. eps\_hostid and ho\_hostid).
Field Name Details
---------- -------
eps_id Episode number
date Episode date
title Episode title
length Episode duration
summary Episode summary
notes Episode show notes
eps_hostid The numerical host id from the 'eps' table
series The series number from the 'eps' table
explicit The explicit marker for the show
eps_license The license for the show
tags The show's tags as a comma-delimited string
version ?Obsolete?
eps_valid The valid value from the 'eps' table
ho_hostid The host id number form the 'hosts' table
ho_host The host name
email The hosts's email address (true address - caution)
profile The host's profile
ho_license The default license for the host
ho_valid The valid value from the 'hosts' table
- **Mailing List Notes**
The variable **includefile** contains the path to the file (which may only be
located in the same directory as the script).
- **Comment Details**
Two hashes are created for comments. The hash named **past** contains comments
to shows before the current month, and **current** contains comments to this
month's shows. Note that these hashes are only populated if the **-comments**
option is provided. Both hashes have the same structure.
Field Name Details
---------- -------
episode Episode number
identifier_url Full show URL
title Episode title
date Episode date
host Host name
hostid Host id number
timestamp Comment timestamp in ISO8601 format
comment_author_name Name of the commenter
comment_title Title of comment
comment_text Text of the comment
comment_timestamp_ut Comment timestamp in Unixtime format
in_range Boolean (0/1) denoting whether the comment was made
in the target month
index The numerical index of the comment for a given show
The purpose of the **in\_range** value is to denote whether a comment was made
in the target month. This is used in the script to split the comments into the
**past** and **current** hashes. It is therefore of little use in the template,
but is retained in case it might be useful. The **index** value can be used in
the template to refer to the comment, make linking URLs etc. It is generated
by the script (unfortunately it couldn't be done in the SQL).
## Filters
A filter called **decode\_entities** is available to the template. The reason
for creating this was when the HTML of a comment is being listed as text
(Unicode actually). Since comment text is stored in the database as HTML with
entities when appropriate this is needed to prevent the plain text showing
_&amp;amp;_ and the like verbatim. It is currently used in **comments\_only.tpl**.
# DIAGNOSTICS
- **Unable to find configuration file ...**
The nominated configuration file in **-config=FILE** (or the default file)
cannot be found.
- **Episode number must be greater than zero**
The **-episode=N** option must use a positive number.
- **Episode must be a number or 'auto'**
The **-episode=** option must be followed by a number or the word 'auto'
- **Error: Unable to find includefile ...**
The include file referred to in the error message is missing.
- **Error: Unable to find template ...**
The template file referred to in the error message is missing.
- **Invalid -from=DATE option '...'**
The date provided through the **-from=DATE** option is invalid. Use an ISO8601
date in the format YYYY-MM-DD.
- **Unable to open ... for writing: ...**
The file specified in the **-out=FILE** option cannot be written to. This may
be because you do not have permission to write to the file or directory.
Further information about why this failed should be included in the message.
- **Unable to initialise for writing: ...**
The script was unable to open STDOUT for writing the report. Further
information about why this failed should be included in the message.
- **Error: wrong show selected**
The **-episode=N** option has been selected and the script is checking the
numbered show but has not found a Community News title.
- **Error: show ... has a date in the past**
The **-episode=** option has been selected and a Community News show entry has
been found in the database. However, this entry is for today's show or is in
the past, which is not permitted. It is possible to override this restriction
by using the **-interlock=PASSWORD** option. See the relevant documentation for
details.
- **Error: show ... already has notes**
The **-episode=** option has been selected and a Community News show entry has
been found in the database. However, this entry already has notes associated
with it and the **-overwrite** option has not been specified.
- **Error: episode ... does not exist in the database**
The **-episode=N** option has been selected but the script cannot find this
episode number in the database.
- **Error: Unable to find an episode for this month's notes**
The **-episode=auto** option has been selected but the script cannot find the
episode for the month being processed.
Possible reasons for this are that the show has not been reserved in the
database or that the title is not as expected. Use **reserve\_cnews** to reserve
the slot. The title should be "HPR Community News for &lt;monthname> &lt;year>".
# CONFIGURATION AND ENVIRONMENT
The script obtains the credentials it requires to open the HPR database from
a configuration file. The name of the file it expects is **.hpr\_db.cfg** in the
directory holding the script. To change this will require changing the script.
The configuration file format is as follows:
<database>
host = 127.0.0.1
port = PORT
name = DATABASE
user = USERNAME
password = PASSWORD
</database>

```
past_upload - version: 0.0.6
Usage: ./past_upload [-h] [-r] [-v] [-d {0|1}] start [count]
Generates the necessary metadata and script and uses them to upload HPR audio
and other show-related files held on the VPS to the Internet Archive. This
script is similar to 'weekly_upload' but it's for dealing with older shows
where we only have the MP3 audio.
Options:
-h Print this help
-v Run in verbose mode where more information is reported
-d 0|1 Dry run: -d 1 (the default) runs the script in dry-run
mode where nothing is changed but the actions that
will be taken are reported; -d 0 turns off dry-run
mode and the actions will be carried out.
-r Run in 'remote' mode, using the live database over an
(already established) SSH tunnel. Default is to run
against the local database.
-Y Answer 'Y' to the confirmation question (really don't
ask at all)
Arguments:
start the starting show number to be uploaded
count (optional, default 1) the number of shows to be
uploaded; cannot exceed 20
Notes:
1. When running on 'borg' the method used is to run in faux 'local' mode.
This means we have an open tunnel to the HPR server (mostly left open) and
the default file .hpr_db.cfg points to the live database via this tunnel.
So we do not use the -r option here. This is a bit of a hack! Sorry!
TODO: Needs fix!
2. There are potential problems when a show has no tags which haven't been
fully resolved. The make_metadata script fails in default mode when it
finds such a show, but this (weekly_upload) script can continue on and run
the generated script which uploads the source audio files. This can mean
the IA items end up as books! In this mode the description is not stored
and so there are no show notes.

# OPTIONS
- **-help**
Prints a brief help message describing the usage of the program, and then exits.
- **-doc**
Prints the entire embedded documentation for the program, then exits.
- **-debug=N**
Enables debugging mode when N > 0 (zero is the default). The levels are:
- **1**
N/A
- **2**
N/A
- **3**
Prints all of the information described at the previous levels.
Prints the files found in the mail spool area.
Prints the internal details of the email, listing the MIME parts (if there are any).
Prints the length of the MIME part matching the desired type, in lines.
Prints the entirety of the internal structure holding details of the mail file
and the comment it contains. This follows the moderation pass.
Prints the SQL that has been constructed to update the database.
- **-\[no\]dry-run**
Controls the program's _dry-run_ mode. It is off by default. In dry-run mode
the program reports what it would do but makes no changes. When off the
program makes all the changes it is designed to perform.
- **-verbose**
This option may be repeated. For each repetition the level of verbosity is
increased. By default no verbosity is in effect and the program prints out the
minimal amount of information.
Verbosity levels:
- **1**
Prints the name of each mail (or JSON) file as it's processed.
Prints any error messages during message validation, which are also being
logged (unless in dry-run mode) and saved for reporting later.
Prints a notification if the comment is added to the database (or that this
would have happened in dry-run mode).
Prints messages about the moving of each mail (or JSON) file from the
processing area, along with any errors accumulated for that file. In dry-run
mode simply indicates what would have happened.
Prints the response code received from the server when invoking the interface
for updating comment files there. If in dry-run mode the message produced
merely indicates what would have happened.
If validation failed earlier on then further information is produced about the
final actions taken on these files.
- **2**
Prints the addresses each mail message is being sent to (unless in JSON mode).
- **3**
Prints the JSON contents of each mail message (or of each JSON file).
- **-\[no\]delay**
This option controls whether the script imposes a delay on comments. The idea
is that if comments are used to rant on a subject or to pass misinformation
delaying them will help to defuse the situation.
The default state is **-nodelay**; a delay is not imposed. Selecting **-delay**
means that comments have to be at least 24 hours old before they are
processed. The length of the delay cannot currently be changed without
altering the script.
- **-\[no\]live**
This option determines whether the program runs in live mode or not. The
default varies depending on which system it is being run on.
IT SHOULD NOT USUALLY BE NECESSARY TO USE THIS!
In live mode the program makes changes to the live database and sends messages
to the live web interface when a comment has been processed. With live mode
off the program assumes it is writing to a clone of the database and it does
not inform the webserver that a comment has been processed.
The default for the copy of the program on the VPS is that live mode is ON.
Otherwise the default is that live mode is OFF. The setting is determined by
the sed script called **fixup.sed** on the VPS. This needs to be run whenever
a new version of the program is released. This is done as follows:
sed -i -f fixup.sed process_comments
- **-\[no\]json**
This option selects JSON mode, which makes the script behave in a different
way from the default mode (**-nojson** or MAIL mode) where it processes email
containing comments.
In JSON mode the script looks in a sub-directory called _json/_ where it
expects to find JSON files. The normal way in which these files arrive in this
directory is by using _scp_ to copy them from the HPR server (the directory
is _/home/hpr/comments_). This is a provision in case the normal route of
sending out email messages has failed for some reason. It also saves the user
from setting up the mail handling infrastructure that would otherwise be
needed.
In JSON mode the mail handling logic is not invoked, files are searched for in
the _json/_ directory and each file is processed, moderation is requested and
the comment is added to the database. In \`**-live**\` mode the server is informed
that the comment has been processed.
The _json/_ directory needs to have three sub-directories: _processed_,
_banned_ and _rejected_. The script will place the processed files into
these sub-directories according to the moderation choice made. This makes it
easier to see what actions were taken and helps avoid repeated processing of
the same comment.
- **-config=FILE**
This option defines a configuration file other than the default
_.hpr\_db.cfg_. The file must be formatted as described below in the section
_CONFIGURATION AND ENVIRONMENT_.
# DESCRIPTION
A script to process new comments, moderate them and add them to the HPR
database.
In the new HPR comment system (released September 2017) a new web form is
presented in association with each show. The form can be used to submit
a comment on the show in question and takes some standard fields: the name of
the commenter, the title of the comment and the body of the comment itself.
Once the comment has been submitted its contents are formatted as a JSON
object and are sent as a mail attachment to the address
_comments@hackerpublicradio.org_.
Recipients of these mail messages can then perform actions on these comments
to cause them to be added to the HPR database. These actions are: approve the
comment, block it (because it is inappropriate or some form of Spam and we
want to prevent any further messages from the associated IP address), or
reject it (delete it). There is also an ignore option which skips the current
comment in this run of the script.
This script can process an entire email message which has been saved to a file
or a file containing the JSON object (as in the email attachment). When
processing email it is expected that it will be found in a maildrop directory,
and when finished the messages will be placed in sub-directories according to
what actions were carried out. A similar logic is used for JSON files; they
are expected to be in a drop area and are moved to sub-directroies after
processing.
## MAIL HANDLING
One way of handling incoming mail is to use a mail client which is capable of
saving messages sent to the above address in the spool area mentioned earlier.
For example, Thunderbird can do this by use of a filter and a plugin. Other
MUA's will have similar capabilities.
When this script is run on the mail spool area it will process all of the
files it finds. For each file it will check its validity in various ways,
display the comment then offer a moderation menu. The moderation options are
described below.
### APPROVE
If a comment is approved then it will be added to the database, the associated
mail file will be moved to a sub-directory (by default called '_processed_'),
and the HPR server will be notified of this action.
### BAN
If a comment is banned then it will not be added to the database. The mail
file will be moved to the sub-directory '_banned_' and the HPR server will be
informed that the IP address associated with the comment should be placed on
a black list.
### REJECT
If a comment is rejected it is not written to the database, the mail file is
moved to the sub-directory '_rejected_' and the HPR server informed that the
comment can be deleted.
### IGNORE
If a comment is ignored it is simply left in the mail spool and no further
processing done on it. It will be eligible for processing again when the
script is next run.
## JSON FILE HANDLING
As described under the description of the **-\[no\]json** option, the script
allows the processing of a multiple JSON files each containing a single
comment. The JSON is checked and all of the comment fields are verified, then
the moderation process is begun.
Moderation in this case consists of the same steps as described above except
that no mail file actions are taken and the JSON file is moved to
a sub-directory after processing.
# DIAGNOSTICS
- **Unable to find configuration file ...**
Type: fatal
The nominated configuration file referenced in **-config=FILE** was not found.
- **No mail found; nothing to do**
Type: fatal
No mail files were found in the mail spool area requiring processing.
- **No JSON files found; nothing to do**
Type: fatal
No JSON files were found in the JSON spool area requiring processing.
- **Failed to read JSON file '...' ...**
Type: fatal
A JSON file in the spool area could not be read with a JSON parser.
- **Failed to parse comment timestamp ...**
Type: fatal
The timestamp must be converted to a format compatible with MySQL/MariaDB but
during this process the parse failed.
- **Failed to open input file '...' ...**
Type: fatal
A mail file in the spool area could not be opened.
- **Failed to move ...**
Type: warning
A mail file could not be moved to the relevant sub-directory.
- **Failed to close input file '...' ...**
Type: warning
A mail file in the spool area could not be closed.
- **Various error messages from the database subsystem**
Type: fatal, warning
An action on the database has been flagged as an error.
- **Various error messages from the Template toolkit**
Type: fatal
An action relating to the template used for the display of the comment has
been flagged as an error.
- **Invalid call to 'call\_back' subroutine; missing key**
Type: warning
The routine 'call\_back' was called incorrectly. The key was missing.
- **Invalid call to 'call\_back' subroutine; invalid action**
Type: warning
The routine 'call\_back' was called incorrectly. The action was invalid.
- **Error from remote server indicating failure**
Type: warning
While attempting to send an action to the remote server with the 'call\_back'
subroutine an error message was received.
# CONFIGURATION AND ENVIRONMENT
## CONFIGURATION
The script obtains the credentials it requires to open the HPR database from
a configuration file. The name of the file it expects is **.hpr\_db.cfg** in the
directory holding the script. This can be changed through the **-config=FILE**
option if required, though the alternative file must conform to the format
below.
The configuration file format is as follows:
<database>
host = 127.0.0.1
port = PORT
name = DATABASE
user = USERNAME
password = PASSWORD
</database>
These settings can be used to connect to an SSH tunnel which has been
connected from a remote system (like the VPS) to the live database. Assuming
the port chosen for this is 3307 something like the following could be used:
<database>
host = 127.0.0.1
port = 3307
name = hpr_hpr
user = hpr_hpr
password = "**censored**"
</database>
A typical Bash script for opening a tunnel might be:
#!/bin/bash
SSHPORT=22
LOCALPORT=3307
REMOTEPORT=3306
ssh -p ${SSHPORT} -f -N -L localhost:${LOCALPORT}:localhost:${REMOTEPORT} hpr@hackerpublicradio.org
## TEMPLATE
The program displays the comment that is currently being processed for
moderation. It uses a template along with the Perl **Template** module to do
this. By default this template is called **process\_comments.tpl**. This can
currently be changed only by changing the program itself.
The template is provided with the following data:
file a scalar containing the name of the file being processed
db a hash containing the details of the show to which the
comment relates, returned from a database query:
id the episode number
date the date of the episode
title the episode title
host the host name
comment a hash containing the fields from the comment:
eps_id the episode number
comment_timestamp date and time of the comment
comment_author_name comment author
comment_title comment title
comment_text comment text
justification justification for posting (if
relevant)
key unique comment key

(e.g. 12-06-2014) or **YYYY-MM-DD** (e.g. 2014-06-12).
If this option is omitted the current date is used.
If the **DATE** part is omitted the script will search the database for the
reservation with the latest date and will use it as the starting point to
generate **-count=COUNT** (or the default 12) reservations.
- **-count=COUNT**
This option defines the number of slots to reserve.
If this option is omitted then 12 slots are reserved.
- **-\[no\]dry-run**
This option in the form **-dry-run** causes the program omit the step of adding
reservations to the database. In the form **-nodry-run** or if omitted, the
program will perform the update(s).
- **-\[no\]silent**
This option in the form **-silent** causes the program omit the reporting of
what it has done. In the form **-nosilent** or if omitted, the program will
report what it is doing.
- **-config=FILE**
This option defines a configuration file other than the default
_.hpr\_db.cfg_. The file must be formatted as described below in the section
_CONFIGURATION AND ENVIRONMENT_.
- **-debug=N**

Values are:
1. Produces details of some of the built-in values used.
2. Produces any output defined for lower levels as well as details of the values
taken from the database for use when reserving the show(s).
3. Produces any output defined for lower levels as well as:
- .
Details of how the \`-from\` date is being interpreted: default, computed from
the database or explicit. The actual date being used is reported.
- .
Details of all dates chosen and their associated sho numbers using the
algorithm "first Monday of the month".
- .
The show title chosen for each reservation is displayed as well as the summary.
# DESCRIPTION
Hacker Public Radio produces a Community News show every month. The show is
recorded on the Saturday before the first Monday of the month, and should be
released as soon as possible afterwards.
This program reserves future slots in the database for upcoming shows. It
computes the date of the first Monday of all of the months in the requested
sequence then determines which show number matches that date. It writes rows
into the _reservations_ table containing the episode number, the host
identifier ('HPR Admins') and the reason for the reservation.
It is possible that an HPR host has already requested the slot that this
program determines it should reserve. When this happens the program increments
the episode number and checks again, and repeats this process until a free
slot is discovered.
It is also possible that a reservation has previously been made in the
_reservations_ table. When this case occurs the program ignores this
particular reservation.
# DIAGNOSTICS
- **Invalid date ...**
The date element of the **-from=DATE** option is not valid. See the description
of this option for details of what formats are acceptable.
- **Various database messages**
The program can generate warning messages from the database.
- **Unable to find host '...' - cannot continue**
The script needs to find the id number relating to the host that will be used
for Community News episodes. It does this by looking in the hosts table for
the name "HPR Volunteers". If this cannot be found, perhaps because it has
been changed, then the script cannot continue. The remedy is to change the
variable $hostname to match the new name.
- **Unable to find series '...' - cannot continue**
The script needs to find the id number relating to the series that will be
used for Community News episodes. It does this by looking in the miniseries
table for the name "HPR Community News". If this cannot be found, perhaps
because it has been changed, then the script cannot continue. The remedy is to
change the variable $seriesname to match the new name.
# CONFIGURATION AND ENVIRONMENT

database by loading them from a configuration file. The file is called
**.hpr\_db.cfg** and should contain the following data:
<database>
host = 127.0.0.1
port = PORT
name = DBNAME
user = USER
password = PASSWORD
</database>
