perf: Avoid creating strings for file extension checks by znelson · Pull Request #1303 · crosspoint-reader/crosspoint-reader

znelson · 2026-03-03T19:13:38Z

Summary

What is the goal of this PR?

This change avoids the pattern of creating a std::string using .substr in order to compare against a file extension literal.

std::string path;
if (path.length() >= 4 && path.substr(path.length() - 4) == ".ext")

The checkFileExtension utility has moved from StringUtils to FsHelpers, to be available to code in lib/. The signature now accepts a std::string_view instead of std::string, which makes the single implementation reusable for Arduino String.

Added utility functions for commonly repeated extensions.

These changes save about 2 KB of flash (5,999,427 to 5,997,343).

📝 Walkthrough

Walkthrough

This PR refactors file extension checking by centralizing logic in FsHelpers. It introduces new namespace-scoped functions (hasJpgExtension, hasPngExtension, etc.), moves normalisePath from a class method to a namespace function, and replaces scattered StringUtils::checkFileExtension calls throughout the codebase with the new helpers, then removes the old StringUtils functions.

Changes

Cohort / File(s)	Summary
FsHelpers Core `lib/FsHelpers/FsHelpers.h`, `lib/FsHelpers/FsHelpers.cpp`	Migrated `normalisePath` from class static to namespace function. Added nine new extension-checking functions (`checkFileExtension`, `hasJpgExtension`, `hasPngExtension`, `hasBmpExtension`, `hasGifExtension`, `hasEpubExtension`, `hasXtcExtension`, `hasTxtExtension`, `hasMarkdownExtension`) with string_view overloads and inline String wrappers.
Image Converters `lib/Epub/Epub/converters/JpegToFramebufferConverter.cpp`, `lib/Epub/Epub/converters/PngToFramebufferConverter.cpp`	Replaced manual lowercase/substring extension checks with FsHelpers extension helpers; added FsHelpers.h includes.
EPUB Processing `lib/Epub/Epub.cpp`	Replaced manual substring-based image format detection (PNG/JPG/GIF) with FsHelpers extension checks in guide parsing and cover/thumb generation.
Archive & Text Format Handling `lib/Xtc/Xtc/XtcTypes.h`, `lib/Txt/Txt.cpp`	Removed `isXtcExtension` helper from xtc namespace; updated Txt.cpp to use FsHelpers extension checks for TXT, BMP, and JPG detection in title extraction and cover generation.
StringUtils Removal `src/util/StringUtils.h`, `src/util/StringUtils.cpp`	Removed `checkFileExtension` overloads and associated `<cstring>` include; retained `sanitizeFilename`.
Activity Layer - File Management `src/activities/home/FileBrowserActivity.cpp`, `src/activities/boot_sleep/SleepActivity.cpp`, `src/activities/reader/ReaderActivity.cpp`	Replaced StringUtils extension checks with FsHelpers equivalents (EPUB, XTC, TXT, Markdown, BMP); removed StringUtils includes; adjusted conditionals for file type filtering.
Activity Layer - Book Handling `src/activities/home/HomeActivity.cpp`, `src/activities/home/RecentBooksActivity.cpp`, `src/RecentBooksStore.cpp`	Replaced StringUtils-based EPUB/XTC/TXT/Markdown checks with FsHelpers helpers; removed StringUtils dependency.
UI & Network Components `src/components/UITheme.h`, `src/components/UITheme.cpp`, `src/network/CrossPointWebServer.cpp`, `src/network/WebDAVHandler.cpp`	Replaced StringUtils extension checks with FsHelpers; updated `UITheme::getFileIcon` signature to accept const reference instead of by-value; removed StringUtils includes.

Learning: Guideline: Strengthen serialization::readString to defend against unbounded growth when reading from disk data. Implement and enforce a maximum allowed length (e.g., a configured or reasonable constant) and validate the incoming length before resizing or allocating. Audit all call sites (e.g., BookMetadataCache, TextBlock, KOReaderCredentialStore, Section cache readers) to ensure they do not rely on unbounded len-based resizing. If the readString API must remain, add internal safeguards (bounds checks, length validation, and error handling) so per-call-site validations are not required. Ensure Section cache files remain versioned (SECTION_FILE_VERSION) and parameter mismatches invalidate caches, but do not rely on unsafe allocations; prefer safe, bounded reads with explicit errors on invalid data.

Learning: In this codebase, assertions are always enabled (no NDEBUG). Use assert() to crash on programmer errors and surface logic bugs during development and in production builds. Do not rely on asserts for runtime error handling; they should enforce invariants that must always hold. Keep asserts side-effect free and inexpensive, and avoid relying on them for user-visible failures. Include <cassert> where appropriate and document the invariant being tested.

Learning: In src/activities/reader/EpubReaderActivity.cpp, the navigateToHref() function uses a fixed-size mini-stack (MAX_FOOTNOTE_DEPTH = 3) for saved positions rather than a dynamic stack. This is intentional to minimize RAM usage on ESP32-C3, which has limited memory. The design accepts that failed navigation at max depth may decrement footnoteDepth even when no push occurred, as a tradeoff for memory efficiency. Users exit by pressing Back three times maximum.

🔇 Additional comments (20)

lib/FsHelpers/FsHelpers.cpp (2)

45-59: LGTM! Well-implemented case-insensitive extension check.

The implementation correctly:

Uses unsigned char cast with tolower to avoid undefined behavior with negative char values

Handles the case where filename is shorter than the extension

Uses std::string_view to avoid allocations as intended

61-79: Clean utility functions with appropriate extension coverage.

The helper functions correctly delegate to checkFileExtension and handle multi-extension formats (.jpg/.jpeg, .xtc/.xtch).

lib/FsHelpers/FsHelpers.h (1)

15-17: LGTM! Efficient inline wrapper pattern.

The String overloads efficiently construct a std::string_view from the Arduino String without copying, achieving the PR's goal of avoiding allocations.

lib/Epub/Epub/converters/PngToFramebufferConverter.cpp (1)

394-396: LGTM! Clean simplification.

Replacing manual extension checking with FsHelpers::hasPngExtension centralizes the logic and benefits from the case-insensitive comparison. The std::string parameter implicitly converts to std::string_view.

lib/Epub/Epub/converters/JpegToFramebufferConverter.cpp (1)

489-491: LGTM! Handles both .jpg and .jpeg variants.

The centralized hasJpgExtension properly checks for both JPEG extension variants, simplifying the converter's format detection.

src/RecentBooksStore.cpp (1)

73-86: LGTM! Extension checks correctly migrated.

The logic flow is preserved:

Check for EPUB → load Epub metadata

Check for XTC → load Xtc metadata

Check for TXT or Markdown → use filename as title

Fallback with empty metadata

All extension predicates properly handle the std::string parameter.

src/activities/boot_sleep/SleepActivity.cpp (2)

64-68: LGTM! BMP validation simplified.

The BMP extension check properly filters non-BMP files in the custom sleep screen directory scan.

231-276: LGTM! Cover sleep screen extension handling preserved.

The conditional chain correctly handles:

XTC files (including .xtch)

TXT files

EPUB files

Fallback to no-cover sleep screen

The logic order and behavior are preserved from the previous implementation.

src/activities/home/FileBrowserActivity.cpp (2)

94-99: LGTM! Efficient file filtering with string_view.

Creating std::string_view from the name buffer avoids allocation during the extension checks. The emplace_back(filename) correctly constructs a std::string in the vector from the string_view.

121-127: LGTM! Cache clearing restricted to EPUB files.

The extension check ensures cache clearing only occurs for .epub files, preserving the original behavior.

src/network/WebDAVHandler.cpp (2)

801-806: LGTM! EPUB cache clearing uses centralized check.

The hasEpubExtension inline wrapper for Arduino String is used correctly here.

808-823: LGTM! MIME type detection refactored cleanly.

The implementation appropriately uses:

Dedicated helpers for common formats (EPUB, TXT, JPG, PNG, GIF)

Generic checkFileExtension for less common formats (PDF, HTML, CSS, JS, JSON, XML, SVG, ZIP, GZ)

This balances convenience with avoiding helper function proliferation.

src/network/CrossPointWebServer.cpp (1)

46-46: LGTM!

The migration to FsHelpers::hasEpubExtension() is correct. Both call sites pass const String& which matches the inline overload in FsHelpers.h that forwards to the std::string_view implementation, avoiding heap allocations.

Also applies to: 393-393

src/activities/reader/ReaderActivity.cpp (1)

24-31: LGTM!

The extension checks correctly use the FsHelpers predicates. The std::string parameters implicitly convert to std::string_view, achieving the PR's goal of avoiding allocations. The logic is preserved:

hasXtcExtension handles both .xtc and .xtch

hasTxtExtension || hasMarkdownExtension correctly treats .md as text files

src/activities/home/HomeActivity.cpp (1)

64-64: LGTM!

The migration to FsHelpers::hasEpubExtension() and FsHelpers::hasXtcExtension() is correct. The book.path (std::string) implicitly converts to std::string_view, avoiding allocations while preserving the existing cover thumbnail generation logic.

Also applies to: 82-82

src/components/UITheme.h (1)

24-24: LGTM!

Changing the parameter from pass-by-value to const std::string& avoids an unnecessary copy when callers pass an lvalue, aligning with the PR's goal of reducing allocations.

lib/Epub/Epub.cpp (2)

106-110: LGTM!

Good use of std::string_view for the intermediate ref variable. The extension checks operate on the view without allocation, and the assignment to std::string imageRef only copies when a valid image reference is found.

541-541: LGTM!

The cover and thumbnail generation logic correctly uses FsHelpers::hasJpgExtension() and FsHelpers::hasPngExtension(). The predicates handle both .jpg and .jpeg extensions, preserving the original behavior while avoiding string allocations.

Also applies to: 574-574, 628-628, 664-664

lib/Txt/Txt.cpp (2)

44-46: LGTM!

The extension check correctly uses FsHelpers::hasTxtExtension(). Since this predicate only matches .txt (exactly 4 characters), the subsequent substr(0, filename.length() - 4) is correct.

115-157: LGTM!

The cover image handling correctly uses FsHelpers::hasBmpExtension() and FsHelpers::hasJpgExtension(). The latter handles both .jpg and .jpeg extensions, preserving the original behavior. The control flow is clear: BMP files are copied directly, JPG/JPEG files are converted, and unsupported formats are logged.

…ader#1303) ## Summary **What is the goal of this PR?** This change avoids the pattern of creating a `std::string` using `.substr` in order to compare against a file extension literal. ```c++ std::string path; if (path.length() >= 4 && path.substr(path.length() - 4) == ".ext") ``` The `checkFileExtension` utility has moved from StringUtils to FsHelpers, to be available to code in lib/. The signature now accepts a `std::string_view` instead of `std::string`, which makes the single implementation reusable for Arduino `String`. Added utility functions for commonly repeated extensions. These changes **save about 2 KB of flash (5,999,427 to 5,997,343)**. --- ### AI Usage While CrossPoint doesn't have restrictions on AI tools in contributing, please be transparent about their usage as it helps set the right context for reviewers.

## Summary It's been a little while since the last release, but the community has been incredibly busy. With 155 changes from 48 contributors (30 of which were new!), there was a lot to cover. Here are some of the highlights: **🔤 Kerning, Ligatures, and Font Improvements** Text rendering gets a significant upgrade with proper kerning and ligature support, fixed-point fractional x-advance for more accurate character placement, and font compression improvements that reduce flash usage. **📝 Footnotes** Footnote anchor navigation lets you select a footnote reference and jump to the footnote text, then jump back. Slim footnotes support is also available for books that use inline footnotes. **📖 EPUB Optimizer** A new integrated EPUB optimizer can clean up and reprocess books for better compatibility with the reader, directly from the device. **🔋 Battery Charging Indicator** You can now see when your device is actively charging, with a visual indicator on the battery icon. **💾 Crash Diagnostics** When something goes wrong, the firmware now dumps a crash report to the SD card — even without USB plugged in. This makes it much easier to report and diagnose issues. **🌐 New Languages** The community continues to expand language support. New in this release: Turkish, Danish, Finnish, Polish, Dutch, Belarusian, Italian, Ukrainian, Romanian, Catalan, Vietnamese, and Kazakh — along with significant improvements to existing translations. **📂 File Management** Multi-select file deletion, BMP image viewer in the file browser, hidden directory browsing, and long-click file deletion from the file browser. **⚡ Performance** Under the hood, text layout switched from `std::list` to `std::vector`, HTML entity lookups are now O(log(n)), font rendering is faster, image decode is 5-20% faster with per-pixel overhead eliminated, and multiple string allocation hot paths were eliminated. Pre-indexing of the next chapter also reduces page-turn latency at chapter boundaries. --- Along with all of the above, there are many other additions including **WebDAV support**, **auto page turn**, **QR code for current page**, **split status bar settings**, **screenshot capture**, **JSON-based settings migration**, **light/dark theme groundwork**, and a long list of stability fixes and translation improvements. ## What's Changed ### Features * feat: Support for kerning and ligatures by @znelson in #873 * feat: footnote anchor navigation by @Uri-Tauber in #1245 * feat: slim footnotes

@znelson

It's been a little while since the last release, but the community has been incredibly busy. With 155 changes from 48 contributors (30 of which were new!), there was a lot to cover. Here are some of the highlights: **🔤 Kerning, Ligatures, and Font Improvements** Text rendering gets a significant upgrade with proper kerning and ligature support, fixed-point fractional x-advance for more accurate character placement, and font compression improvements that reduce flash usage. **📝 Footnotes** Footnote anchor navigation lets you select a footnote reference and jump to the footnote text, then jump back. Slim footnotes support is also available for books that use inline footnotes. **📖 EPUB Optimizer** A new integrated EPUB optimizer can clean up and reprocess books for better compatibility with the reader, directly from the device. **🔋 Battery Charging Indicator** You can now see when your device is actively charging, with a visual indicator on the battery icon. **💾 Crash Diagnostics** When something goes wrong, the firmware now dumps a crash report to the SD card — even without USB plugged in. This makes it much easier to report and diagnose issues. **🌐 New Languages** The community continues to expand language support. New in this release: Turkish, Danish, Finnish, Polish, Dutch, Belarusian, Italian, Ukrainian, Romanian, Catalan, Vietnamese, and Kazakh — along with significant improvements to existing translations. **📂 File Management** Multi-select file deletion, BMP image viewer in the file browser, hidden directory browsing, and long-click file deletion from the file browser. **⚡ Performance** Under the hood, text layout switched from `std::list` to `std::vector`, HTML entity lookups are now O(log(n)), font rendering is faster, image decode is 5-20% faster with per-pixel overhead eliminated, and multiple string allocation hot paths were eliminated. Pre-indexing of the next chapter also reduces page-turn latency at chapter boundaries. --- Along with all of the above, there are many other additions including **WebDAV support**, **auto page turn**, **QR code for current page**, **split status bar settings**, **screenshot capture**, **JSON-based settings migration**, **light/dark theme groundwork**, and a long list of stability fixes and translation improvements. * feat: Support for kerning and ligatures by @znelson in crosspoint-reader#873 * feat: footnote anchor navigation by @Uri-Tauber in crosspoint-reader#1245 * feat: slim

## Summary It's been a little while since the last release, but the community has been incredibly busy. With 155 changes from 48 contributors (30 of which were new!), there was a lot to cover. Here are some of the highlights: **🔤 Kerning, Ligatures, and Font Improvements** Text rendering gets a significant upgrade with proper kerning and ligature support, fixed-point fractional x-advance for more accurate character placement, and font compression improvements that reduce flash usage. **📝 Footnotes** Footnote anchor navigation lets you select a footnote reference and jump to the footnote text, then jump back. Slim footnotes support is also available for books that use inline footnotes. **📖 EPUB Optimizer** A new integrated EPUB optimizer can clean up and reprocess books for better compatibility with the reader, directly from the device. **🔋 Battery Charging Indicator** You can now see when your device is actively charging, with a visual indicator on the battery icon. **💾 Crash Diagnostics** When something goes wrong, the firmware now dumps a crash report to the SD card — even without USB plugged in. This makes it much easier to report and diagnose issues. **🌐 New Languages** The community continues to expand language support. New in this release: Turkish, Danish, Finnish, Polish, Dutch, Belarusian, Italian, Ukrainian, Romanian, Catalan, Vietnamese, and Kazakh — along with significant improvements to existing translations. **📂 File Management** Multi-select file deletion, BMP image viewer in the file browser, hidden directory browsing, and long-click file deletion from the file browser. **⚡ Performance** Under the hood, text layout switched from `std::list` to `std::vector`, HTML entity lookups are now O(log(n)), font rendering is faster, image decode is 5-20% faster with per-pixel overhead eliminated, and multiple string allocation hot paths were eliminated. Pre-indexing of the next chapter also reduces page-turn latency at chapter boundaries. --- Along with all of the above, there are many other additions including **WebDAV support**, **auto page turn**, **QR code for current page**, **split status bar settings**, **screenshot capture**, **JSON-based settings migration**, **light/dark theme groundwork**, and a long list of stability fixes and translation improvements. ## What's Changed ### Features * feat: Support for kerning and ligatures by @znelson in crosspoint-reader#873 * feat: footnote anchor navigation by @Uri-Tauber in

## Summary It's been a little while since the last release, but the community has been incredibly busy. With 155 changes from 48 contributors (30 of which were new!), there was a lot to cover. Here are some of the highlights: **🔤 Kerning, Ligatures, and Font Improvements** Text rendering gets a significant upgrade with proper kerning and ligature support, fixed-point fractional x-advance for more accurate character placement, and font compression improvements that reduce flash usage. **📝 Footnotes** Footnote anchor navigation lets you select a footnote reference and jump to the footnote text, then jump back. Slim footnotes support is also available for books that use inline footnotes. **📖 EPUB Optimizer** A new integrated EPUB optimizer can clean up and reprocess books for better compatibility with the reader, directly from the device. **🔋 Battery Charging Indicator** You can now see when your device is actively charging, with a visual indicator on the battery icon. **💾 Crash Diagnostics** When something goes wrong, the firmware now dumps a crash report to the SD card — even without USB plugged in. This makes it much easier to report and diagnose issues. **🌐 New Languages** The community continues to expand language support. New in this release: Turkish, Danish, Finnish, Polish, Dutch, Belarusian, Italian, Ukrainian, Romanian, Catalan, Vietnamese, and Kazakh — along with significant improvements to existing translations. **📂 File Management** Multi-select file deletion, BMP image viewer in the file browser, hidden directory browsing, and long-click file deletion from the file browser. **⚡ Performance** Under the hood, text layout switched from `std::list` to `std::vector`, HTML entity lookups are now O(log(n)), font rendering is faster, image decode is 5-20% faster with per-pixel overhead eliminated, and multiple string allocation hot paths were eliminated. Pre-indexing of the next chapter also reduces page-turn latency at chapter boundaries. --- Along with all of the above, there are many other additions including **WebDAV support**, **auto page turn**, **QR code for current page**, **split status bar settings**, **screenshot capture**, **JSON-based settings migration**, **light/dark theme groundwork**, and a long list of stability fixes and translation improvements. ## What's Changed ### Features * feat: Support for kerning and ligatures by @znelson in crosspoint-reader#873 * feat: footnote anchor navigation by @Uri-Tauber in
