TODO - some of these are out of date/done, needs pruning |
| 17 |
// On plugins restore, don't let UD over-write itself - because this usually means a down-grade. Since upgrades are db-compatible, there's no reason to downgrade. |
| 18 |
// Schedule a task to report on failure |
| 19 |
// Get user to confirm if they check both the search/replace and wp-config boxes |
| 20 |
// Apparently Google's console has changed again... |
| 21 |
// Auto-split. Helps on one.com. Check the log sent by #6292 |
| 22 |
// Tweak the display so that users seeing resumption messages don't think it's stuck |
| 23 |
// Store/show current Dropbox account |
| 24 |
// On restore, check for some 'standard' PHP modules (prevents support requests related to them) -e.g. GD, Curl |
| 25 |
// Recognise known huge non-core tables on restore, and postpone them to the end (AJAX method?) |
| 26 |
// Add a cart notice if people have DBSF=quantity1 |
| 27 |
// Pre-restore actually unpack the zips if they are not insanely big (to prevent the restore crashing at this stage if there's a problem) |
| 28 |
// Integrate jstree for a nice files-chooser; use https://wordpress.org/plugins/dropbox-photo-sideloader/ to see how it's done |
| 29 |
// Verify that attempting to bring back a MS backup on a non-MS install warns the user |
| 30 |
// Pre-schedule resumptions that we know will be scheduled later |
| 31 |
// Make SFTP chunked (there is a new stream wrapper) |
| 32 |
// If we're on the last resumption, zipping, and nothing's succeeded for a while, then auto-split |
| 33 |
// Change add-ons screen, to be less confusing for people who haven't yet updated but have connected |
| 34 |
// Change migrate window: 1) Retain link to article 2) Have selector to choose which backup set to migrate - or a fresh one 3) Have option for FTP/SFTP/SCP despatch 4) Have big "Go" button. Have some indication of what happens next. Test the login first. Have the remote site auto-scan its directory + pick up new sets. Have a way of querying the remote site for its UD-dir. Have a way of saving the settings as a 'profile'. Or just save the last set of settings (since mostly will be just one place to send to). Implement an HTTP/JSON method for sending files too. |
| 35 |
// Post restore, do an AJAX get for the site; if this results in a 500, then auto-turn-on WP_DEBUG |
| 36 |
// Place in maintenance mode during restore - ? |
| 37 |
// Test Azure: https://blogs.technet.com/b/blainbar/archive/2013/08/07/article-create-a-wordpress-site-using-windows-azure-read-on.aspx?Redirected=true |
| 38 |
// Seen during autobackup on 1.8.2: Warning: Invalid argument supplied for foreach() in /home/infinite/public_html/new/wp-content/plugins/updraftplus/updraftplus.php on line 1652 |
| 39 |
// Add some kind of automated scan for post content (e.g. images) that has the same URL base, but is not part of WP. There's an example of such a site in tmp-rich. |
| 40 |
// Free/premium comparison page |
| 41 |
// Complete the tweak to bring the delete-old-dirs within a dialog (just needed to deal wtih case of needing credentials more elegantly). |
| 42 |
// Add note to support page requesting that non-English be translated |
| 43 |
// More locking: lock the resumptions too (will need to manage keys to make sure junk data is not left behind) |
| 44 |
// See: ftp-logins.log - would help if we retry FTP logins after 10 second delay (not on testing), to lessen chances of 'too many users - try again later' being terminal. Also, can we log the login error? |
| 45 |
// Deal with missing plugins/themes/uploads directory when installing |
| 46 |
// Bring down interval if we are already in upload time (since zip delays are no longer possible). See: options-general-11-23.txt |
| 47 |
// Add FAQ - can I get it to save automatically to my computer? |
| 48 |
// Pruner assumes storage is same as current - ? |
| 49 |
// Include blog feed in basic email report |
| 50 |
// Detect, and show prominent error in admin area, if the slug is not updraftplus/updraftplus.php (one Mac user in the wild managed to upload as updraftplus-2). |
| 51 |
// Pre-schedule future resumptions that we know will be scheduled; helps deal with WP's dodgy scheduler skipping some. (Then need to un-schedule if job finishes). |
| 52 |
// Dates in the progress box are apparently untranslated |
| 53 |
// Add-on descriptions are not internationalised |
| 54 |
// Nicer in-dashboard log: show log + option to download; also (if 'reporting' add-on available) show the HTML report from that |
| 55 |
// Take a look at logfile-to-examine.txt (stored), and the pattern of detection of zipfile contents |
| 56 |
// http://www.phpclasses.org/package/8269-PHP-Send-MySQL-database-backup-files-to-Ubuntu-One.html |
| 57 |
// Put the -old directories in updraft_dir instead of present location. Prevents file perms issues, and also will be automatically excluded from backups. |
| 58 |
// Add feature in Backup Now to skip cloud despatch for this backup |
| 59 |
// Test restores via cloud service for small $??? (Relevant: http://browshot.com/features) (per-day? per-install?) |
| 60 |
// Warn/prevent if trying to migrate between sub-domain/sub-folder based multisites |
| 61 |
// Don't perform pruning when doing auto-backup? |
| 62 |
// Post-migrate, notify the user if on Apache but without mod_rewrite (has been seen in the wild) |
| 63 |
// Pre-check the search/replace box if migration detected |
| 64 |
// Can some tables be omitted from the search/replace on a migrate? i.e. Special knowledge? |
| 65 |
// Put a 'what do I get if I upgrade?' link into the mix |
| 66 |
// Add to admin bar (and make it something that can be turned off) |
| 67 |
// If migrated database from somewhere else, then add note about revising UD settings |
| 68 |
// Strategy for what to do if the updraft_dir contains untracked backups. Automatically rescan? |
| 69 |
// MySQL manual: See Section 8.2.2.1, Speed of INSERT Statements. |
| 70 |
// Exempt UD itself from a plugins restore? (will options be out-of-sync? exempt options too?) |
| 71 |
// Post restore/migrate, check updraft_dir, and reset if non-existent |
| 72 |
// Auto-empty caches post-restore/post-migration (prevent support requests from people with state/wrong cacheing data) |
| 73 |
// Show 'Migrate' instead of 'Restore' on the button if relevant |
| 74 |
// Test with: http://wordpress.org/plugins/wp-db-driver/ |
| 75 |
// Backup notes |
| 76 |
// Automatically re-count folder usage after doing a delete |
| 77 |
// Switch zip engines earlier if no progress - see log.cfd793337563_hostingfails.txt |
| 78 |
// The delete-em at the end needs to be made resumable. And to only run on last run-through (i.e. no errors, or no resumption) |
| 79 |
// Incremental - can leverage some of the multi-zip work??? |
| 80 |
// Put in a help link to explain what WordPress core (including any additions to your WordPress root directory) does (was asked for support) |
| 81 |
// More databases |
| 82 |
// Multiple files in more-files |
| 83 |
// On multisite, the settings should be in the network panel. Connection settings need migrating into site options. |
| 84 |
// On restore, raise a warning for ginormous zips |
| 85 |
// Detect double-compressed files when they are uploaded (need a way to detect gz compression in general) |
| 86 |
// Log migrations/restores, and have an option for auto-emailing the log |
| 87 |
# Email backup method should be able to force split limit down to something manageable - or at least, should make the option display. (Put it in email class. Tweak the storage dropdown to not hide stuff also in expert class if expert is shown). |
| 88 |
// What happens if you restore with a database that then changes the setting for updraft_dir ? Should be safe, as the setting is cached during a run: double-check. |
| 89 |
// Multi-site manager at updraftplus.com |
| 90 |
// Import/slurp backups from other sites. See: http://www.skyverge.com/blog/extending-the-wordpress-xml-rpc-api/ |
| 91 |
// More sophisticated options for retaining/deleting (e.g. 4/day for X days, then 7/week for Z weeks, then 1/month for Y months) |
| 92 |
// Unpack zips via AJAX? Do bit-by-bit to allow enormous opens a better chance? (have a huge one in Dropbox) |
| 93 |
// Put in a maintenance-mode detector |
| 94 |
// Add update warning if they've got an add-on but not connected account |
| 95 |
// Detect CloudFlare output in attempts to connect - detecting cloudflare.com should be sufficient |
| 96 |
// Bring multisite shop page up to date |
| 97 |
// Re-do pricing + support packages |
| 98 |
// More files: back up multiple directories, not just one |
| 99 |
// Give a help page to go with the message: A zip error occurred - check your log for more details (reduce support requests) |
| 100 |
// Exclude .git and .svn by default from wpcore |
| 101 |
// Add option to add, not just replace entities on restore/migrate |
| 102 |
// Add warning to backup run at beginning if -old dirs exist |
| 103 |
// Auto-alert if disk usage passes user-defined threshold / or an automatically computed one. Auto-alert if more backups are known than should be (usually a sign of incompleteness). Actually should just delete unknown backups over a certain age. |
| 104 |
// Generic S3 provider: add page to site. S3-compatible storage providers: http://www.dragondisk.com/s3-storage-providers.html |
| 105 |
// Importer - import backup sets from another WP site directly via HTTP |
| 106 |
// Option to create new user for self post-restore |
| 107 |
// Auto-disable certain cacheing/minifying plugins post-restore |
| 108 |
// Enhance Google Drive support to not require registration, and to allow offline auth |
| 109 |
// Add note post-DB backup: you will need to log in using details from newly-imported DB |
| 110 |
// Make search+replace two-pass to deal with moving between exotic non-default moved-directory setups |
| 111 |
// Get link - http://www.rackspace.com/knowledge_center/article/how-to-use-updraftplus-to-back-up-cloud-sites-to-cloud-files |
| 112 |
// 'Delete from your webserver' should trigger a rescan if the backup was local-only |
| 113 |
// Notify user only if backup fails |
| 114 |
// Encrypt archives - http://www.frostjedi.com/phpbb3/viewtopic.php?f=46&t=168508&p=391881&e=391881 |
| 115 |
// Option for additive restores - i.e. add content (themes, plugins,...) instead of replacing |
| 116 |
// Testing framework - automated testing of all file upload / download / deletion methods |
| 117 |
// Though Google Drive code users WP's native HTTP functions, it seems to not work if WP natively uses something other than curl |
| 118 |
// Ginormous tables - need to make sure we "touch" the being-written-out-file (and double-check that we check for that) every 15 seconds - https://friendpaste.com/697eKEcWib01o6zT1foFIn |
| 119 |
// With ginormous tables, log how many times they've been attempted: after 3rd attempt, log a warning and move on. But first, batch ginormous tables (resumable) |
| 120 |
// Import single site into a multisite: http://codex.wordpress.org/Migrating_Multiple_Blogs_into_WordPress_3.0_Multisite, http://wordpress.org/support/topic/single-sites-to-multisite?replies=5, http://wpmu.org/import-export-wordpress-sites-multisite/ |
| 121 |
// Selective restores - some resources |
| 122 |
// When you migrate/restore, if there is a .htaccess, warn/give option about it. |
| 123 |
// 'Show log' should be done in a nice pop-out, with a button to download the raw |
| 124 |
// delete_old_dirs() needs to use WP_Filesystem in a more user-friendly way when errors occur |
| 125 |
// Bulk download of entire set at once (not have to click 7 times). |
| 126 |
// Restoration should also clear all common cache locations (or just not back them up) |
| 127 |
// Deal with gigantic database tables - e.g. those over a million rows on cheap hosting. |
| 128 |
// When restoring core, need an option to retain database settings / exclude wp-config.php |
| 129 |
// If migrating, warn about consequences of over-writing wp-config.php |
| 130 |
// Produce a command-line version of the restorer (so that people with shell access are immune from server-enforced timeouts) |
| 131 |
// Restorations should be logged also |
| 132 |
// Log the restore operation |
| 133 |
// Migrator - list+download from remote, kick-off backup remotely |
| 134 |
// April 20, 2015: This is the date when the Google Documents API is likely to stop working (https://developers.google.com/google-apps/documents-list/terms) |
| 135 |
// Search for other TODO-s in the code |
| 136 |
// Opt-in non-personal stats + link to aggregated results |
| 137 |
// Stand-alone installer - take a look at this: http://wordpress.org/extend/plugins/duplicator/screenshots/ |
| 138 |
// More DB add-on (other non-WP tables; even other databases) |
| 139 |
// Unlimited customers should be auto-emailed each time they add a site (security) |
| 140 |
// Update all-features page at updraftplus.com (not updated after 1.5.5) |
| 141 |
// Save database encryption key inside backup history on per-db basis, so that if it changes we can still decrypt |
| 142 |
// Switch to Google Drive SDK. Google folders. https://developers.google.com/drive/folder |
| 143 |
// AJAX-ify restoration |
| 144 |
// Warn Premium users before de-activating not to update whilst inactive |
| 145 |
// Ability to re-scan existing cloud storage |
| 146 |
// Dropbox uses one mcrypt function - port to phpseclib for more portability |
| 147 |
// Store meta-data on which version of UD the backup was made with (will help if we ever introduce quirks that need ironing) |
| 148 |
// Send the user an email upon their first backup with tips on what to do (e.g. support/improve) (include legacy check to not bug existing users) |
| 149 |
// GoogleDrive +Rackspace folders |
| 150 |
//Do an automated test periodically for the success of loop-back connections |
| 151 |
//When a manual backup is run, use a timer to update the 'Download backups and logs' section, just like 'Last finished backup run'. Beware of over-writing anything that's in there from a resumable downloader. |
| 152 |
//Change DB encryption to not require whole gzip in memory (twice) |
| 153 |
//Add YouSendIt/Hightail, Copy.Com, Box.Net, SugarSync, Me.Ga support?? |
| 154 |
//Make it easier to find add-ons |
| 155 |
// On restore, move in data, not the whole directory (gives more flexibility on file permissions) |
| 156 |
// Move the inclusion, cloud and retention data into the backup job (i.e. don't read current config, make it an attribute of each job). In fact, everything should be. So audit all code for where get_option is called inside a backup run: it shouldn't happen. |
| 157 |
// Should we resume if the only errors were upon deletion (i.e. the backup itself was fine?) Presently we do, but it displays errors for the user to confuse them. Perhaps better to make pruning a separate scheuled task?? |
| 158 |
// Create a "Want Support?" button/console, that leads them through what is needed, and performs some basic tests... |
| 159 |
// Chunking + resuming on SFTP |
| 160 |
// Add-on to check integrity of backups |
| 161 |
// Add-on to manage all your backups from a single dashboard |
| 162 |
// Provide backup/restoration for UpdraftPlus's settings, to allow 'bootstrap' on a fresh WP install - some kind of single-use code which a remote UpdraftPlus can use to authenticate |
| 163 |
// Multiple schedules |
| 164 |
// Allow connecting to remote storage, scanning + populating backup history from it |
| 165 |
// GoogleDrive in-dashboard download resumption loads the whole archive into memory - should instead either chunk or directly stream fo the file handle |
| 166 |
// Multisite add-on should allow restoring of each blog individually |
| 167 |
// Remove the recurrence of admin notices when settings are saved due to _wp_referer |
| 168 |
|
| 169 |
Encrypt filesystem, if memory allows (and have option for abort if not) |
| 170 |
// New sub-module to verify that the backups are there, independently of backup thread |

/* Logs the given line, adding (relative) time stamp and newline |

Note these subtleties of log handling: |
| 639 |
- Messages at level 'error' are not logged to file - it is assumed that a separate call to log() at another level will take place. This is because at level 'error', messages are translated; whereas the log file is for developers who may not know the translated language. Messages at level 'error' are for the user. |
| 640 |
- Messages at level 'error' do not persist through the job (they are only saved with save_backup_history(), and never restored from there - so only the final save_backup_history() errors persist); we presume that either a) they will be cleared on the next attempt, or b) they will occur again on the final attempt (at which point they will go to the user). But... |
| 641 |
- ... messages at level 'warning' persist. These are conditions that are unlikely to be cleared, not-fatal, but the user should be informed about. The $uniq_id field (which should not be numeric) can then be used for warnings that should only be logged once |
| 642 |
$skip_dblog = true is suitable when there's a risk of excessive logging, and the information is not important for the user to see in the browser on the settings page |
